A family of cole- opterous insects, belonging to the section Pentamera, and to the sub-section Lamellicornes, forming a por- tion of the great Linnaean genus Scarabceus, and corresponding with the section Melitophila of the Regne Animal. The body is depressed, generally oval, and gaily coloured ; the head and thorax seldom cornuted ; the thorax ovate-quadrate, or suborbi- The Rose-chaffer in its different shapes, cular ; a corneous plate (forming portion of the sides of the meso-thorax, greatly developed,) occupies the space between the posterior and lateral margins of the thorax, and the external base of the elytra. The elytra are generally shorter than the body, the extremity of which is consequently exposed ; the sternum is often prolonged into a point, thus resem- bling the Buprestidce; the scutellum is generally distinct, and the tarsi are provided with equal sized simple claws ; the antennae are ten jointed, the club being composed of three joints. The structure of the mouth, which affords so complete an idea of the nature of the food of insects, is here remarkable. The upper lip and jaws, instead of being horny, as in the majority of beetles, are reduced to thin membranous plates, incapable of gnawing ; the maxilhp are also terminated by a very hairy lobe, in the shape of a pencil, without horny teeth, and are only furnished with a single palpus. Now, on comparing this description with the figure of the under jaw of a pre- dacious beetle, given in our article CARABID^., the difference will be perceived to be very striking. In NAT. HIST. — Vol.. II. the latter, the structure indicates strong biting and lacerating powers ; but in the Cetonia:, the formation will serve only for lapping up vegetable juices, and we accordingly find that some of the species prefer the sap which flows from the wounds of trees, whilst others sip, with evident delight, the nectar of flowers. These insects are distinguished from the family of cock-chaffers (Melolonthida:}, by the maxillae not being terminated by several robust teeth as in the latter, by the upper lip being concealed by the clypeus, and by the antennae, which are terminated only by a three- jointed fan. The green rose-chaffer ( Cetonia auratd) is one of the commonest, as well as one of the most beautiful, of our British beetles. It is found, very abundantly, during the summer months, especially in gardens, and frequenting the flowers of the rose, elder, peonv, &(•„ We have also noticed that it is extremely partial to the privet, having observed a hedge of that tree, in the neighbourhood of Fulham, completely swarming with them. They fly well, with a consider- able humming noise, during the hottest part of the day. Tliis species is of a fine golden green colour, very shining above, and of a bright copper colour beneath ; the wing covers are ornamented, near the tips, with numerous transverse narrow white markings. Ac- cording to Latreille, these insects do not attack the essential parts of flowers, contenting themselves with merely sucking the honey from the bottom of the corolla. However, this may be, it appears that another species of the genus, (the Cetonia hirtd), is very injurious to the flowers of the apricot in Malta — an account of its ravages having been published by M. St. John, in the Magazine of Natural History, No. XXIII. Of this insect, which the Maltese call Bouzuff, and the English inhabitants the Botany Bay, this author observes, " After he has filled himself, he retires under ground till the March apricot blossoms, when he emerges, and I am, for two months, obliged to have people employed solely to pick him off the blossoms, of which he readily eats the nectary, and having eaten one he goes to the next ; he is very active, and flies like a bee. When the roses are in blossom, these beasts are so fond of them, that you may take twenty out of one flower, and in ten minutes as many more — a dark-coloured flower they never touch." Upon the commencement of this passage we would, however, observe, that it would therefrom be naturally inferred, that the writer sup- posed either that the animal maintained the same form on emerging in March, as it possessed on retiring under ground, or, at least, that the grub of the cetonia A CEYLONITE — CHvETODON. had filled itself (it is not stated with what) in an exposed manner above ground, then retired into the earth, from whence it emerged in the perfect state in March. Neither of these ideas would, however, be correct, because the perfect cetouia only appears above ground for a short time in spring and summer, retiring thither again tor the purpose alone of deposit- ing her eggs, which is"the last act of her existence. Moreover, the grubs of the cetonia do not feed above ground, but in rotten timber and wood ; and, indeed, it is remarkable that the larva and pupa of the com- mon rose-chatfer are often found under ground in ants' nests, where, it would seem, they support themselves by feeding upon the bits of wood of which the nests are composed, and without being attacked by their hostile hosts. From this circumstance they are called, ui some countries, the king of the ants. After remain- ing two or three years in the larva state, they may be considered as full grown, when the larva makes a cocoon of bits of sticks, giuten, &c., in whir*" it becomes an inactive pupa, and from which, in the following summer, it emerges. Some difference of opinion exists as to the food of the larva of these insects ; some authors supposing that they feed upon the earth in which they live, whilst others state that they attack the roots of living plants ; and by some it is affirmed, that in this state they scarcely do ai>" mischief to plants, feeding upon putrescent wood. This family, which corresponds with Latreille's section Mcliiophili, is divisible into three sections. First, the Trie/rides, having the sternum not produced into a point, the thoracic lateral scales not developed, and the lower jaws not concealed by the chin. Here belong the British genera Trichius, Gnorimus, and Valgus,w\& some others proposed by Mr. Kirby in the Zoological Journal, and by Messrs. Gory and Per- cheron in their very beautiful Monographic des Cetoines, now in course of publication. In this first section we possess but four British species, which have been until recently placed in the genus Tiichius, but the diversity of their habits sufficiently warrants their separation. Thus the beautiful Trichius fasdatus is always found upon flowers, whilst the Gnorimus variabilis not only passes its larva state within the bodies of decayed oak trees, but is found, on arriving at the perfect state, on the trunks of such trees. The Valgus hemipterus, on the contrary, is commonly found on the ground, where it creeps but slowly. This, and some North American species, are dis- ! tinguished by the horny spear-shaped ovipositor at the extremity of the body, which evidently is employed by them to bore a hole in the earth for the reception of their eggs. The second section, Go/iatfudes, is distinguished ; from the preceding by the large size of the mentum ' which conceals the lower jaws. Here belong various exotic genera, of whose habits nothing is known, including, however, some of the largest and most beautiful species of lamellicorn insects. The third section, Cetoniides, have the sternum pointed, and the lateral thoracic plates developed. Here Belongs the British genus Cetonia (containing two British species) and various other exotic genera. CEYLONITE. A mineral which derives its name from Ceylon, to which island it was originally supposed to be exclusively confined. It is now, however, found in considerable quantities in the rocky beds of the Rhine, and in several volcanic districts. This mineral is distinguished from SPINEL, which see, by its semi-metallic lustre, inferior hard- ness, greater specific gravity,and inferior transparency. When it occurs in grains, it is apt to be confounded with tourmaline ; but its semi-metallic lustre, greater specific gravity, and its not becoming electric by heating, distinguish it from that mineral. CH^EROPOTAMUS. A name given by Cuvier to a genus of fossil pachydermata found in the gypsum in the neighbourhood of Paris, where it accompanies the remains of the anoplotheria and palaeotheria, but is of much rarer occurrence than either of these. But little of this animal has been found, excepting the teeth and some parts of the head. The incisors (if there were any) have not hitherto been discovered. The canine tooth in the lower jaw is pointed, and tolerably large, and an j empty space occurs between it and the first rnolar- tooth, which is conical, pointed, and slightly com- pressed, but by no means trenchant ; it has two thick roots, which separate as they enter the alveolus. The second molar is rather more compressed, having also two roots ; and behind its points, which are blunt, are two other points much lower, and scarcely projecting, which form a second lobe. Two teeth follow, which are tuberculated, having four principal tubercles on the coronal, which is nearly rectangular ; two smaller tubercles occur in the middle of the others, and there are some other inequalities about their bases. These teeth resemble very closely the third and fourth molar teeth of the babyroussa, and, generally speaking, teeth of this description indicate an animal of the swine family ; but no known animal of this kind has the first molar of this conical form, and the pecari alone has a canine tooth as small as the chaeropotamus, and besides is a much smaller animal than this appears to have been. From these and other fragments, Cuvier was led to the conclusion, that the plaster quarries contain the remains of an animal approximating more nearly to the genus Porcus, than either the anoplothetium, or the palaeotherium, which however differed in many particulars from any species of swine now existing. He offers as a conjecture, that the dichobunes, whose feet so nearly resemble those of swine, approached very nearly to this new genus, and possibly formed the link between it and the anoplotheria, properly so called. But one species (the Parisiensis) has hitherto been noticed. CH^ETODON— bristle-tooth. A genus of spinous finned fishes, belonging to Cuvier's sixth family of the division, or those with scales on the fins. They obtain their name from the very peculiar form of the teeth, which are long, slender, and bristle shaped, ranged in several rows, and bearing some resemblance to brushes. Their mouth is very small ; their dorsal and anal fins are covered with scales, not easily dis- tinguishable from those on the back. They are exceedingly numerous in the warm seas, and many of them are so gay in their colours, that they are sought after with some avidity by collectors, as cabinet fish. Their intestines are long and large, with numerous long but slender caeca. The air-bladder is very large. They are usually found near reefs and rocky shores ; La Cepede has enumerated forty-two species. Their flesh is excellent food, and they are much sought after by the sailors. They are remarkable for their form, and the brilliancy and variety of their colours. The limits by which the different species are separated are ill C H M T O D O N. defined, so that much confusion prevails in their nomenclature. They ;ill inhabit ihe seas of tropical countries, and were unknown or disregarded by the ancients. The skeletons of some species have been found, along1 with other ruiiio of the animal kingdom, in the strata at Mount l.ulca. La Cepede particularly mentions the remains of the C. vespcrtilio and term. The (,'. wargiiKthtii appears to prefer the mouths of rivers, is very common at the Antilles, and its rlesh is good. The flesh of the C. macrnlepidotus, a native of the East indies, i's said, in point of delicacy, to resem- ble the sole. But the most extraordinary species is the C. roxtmtns, a native of the fresh waters of India. Dr. Shaw, after informing us that its prey consists of the smaller kinds of insects, says, " When it observes one of these, either hovering over the water or seated on some aquatic plant, it shoots against it from its tuberous snout a drop of water, with so sure an aim, as generally to lay it dead, or at least stupified, on the surface. In shooting at a sitting insect, it is commonly observed to approach within the distance of from six to four inches, before it c:;plodes the water. When kept in a state of confinement in a large vessel of water, it is said to afford high entertainment by its dexterity in this exercise ; since, if a fly or other insect be fastened to the edge of the vessel, the fish immediately perceives it, and continues to shoot at it with such admirable skill, as very rarely to miss the mark." In whatever part of the world they are found, these fishes are equally remarkable for their singular forms, their brilliant colours, and their great activity. They are so remarkable in these respects, that they have sometimes been described as occupying a similar place in the tropical seas to that which the parrots occupy in the tropical forests ; and though, as is the case with all fishes, their colours fade much more after death than those of birds ; they perhaps excel the parrots in brilliancy while they are alive. All their colours ha>e a metallic lustre, and though some of them are of one very intense colour, as for instance golden yellow, ultra-marine blue, or rich bronze, when the ' *h is at rest, yet, when it moves, they are all iride- scent and sparkle with a gem-like lustre. They are also exceedingly numerous, both in species and indi- viduals, and as they keep near the surface, anc frequently spring into the air, they have a very brilliant effect. The variety of them is, indeed, so great, tnat they have hitherto set description at defiance and a mere list of them would occupy too much space in a work of this kind. Cuvier divides them into several sub-genera, of which, and one or two of the leading species, we shall give very short notices. I. CH^TODONS properly called. These have the body more or less elliptic, the spmous and soft rays o the fins are continued in a curve which is not very uniform ; the muzzle is differently produced in differ ent species ; and in some of them the gill-flap is armec with a small tooth. The spines of the dorsal are sometimes very much produced. Most of the species of this sub-genus inhabit the eastern tropical seas The following are some of the principal genera : — Chtetodon stria I us, this species is sometimes callec the zebra, on account of its stripes. It has the heac and gill-cover armed with the same scales as the back two openings to each nostril, the vent much nearer the head than the tail, the caudal fin is rounded. Its general colours are : — the ground a beautiful yellow with four or five transverse bands of brown on the sides, and the pectoral fins black. It is one of the argest species, and also plentiful ; and its flesh, which s white, firm, and well flavoured, is much sought after. Choi todou nnimucidatiis. This species is sometimes called the black spot ; its distinguishing characters are, he tail forked, a black band crossing the nape, inclini- ng the eyes, and extending down to the gill-covers, and a single large spot on each side of the back. It s found principally in the North Pacific, toward the Japan and Philippean islands. Chcetodon capistratm. This species has the tail rounded, the black band on the head straighter, and the black spots on the back surrounded with white. It is found in the same seas with the former species. Those which we have mentioned are but a very few of the species or varieties of this abundant and in- teresting sub-genus ; but the differences, though con- spicuous enough, are not very important, as they are almost wholly differences of colour only. II. CHKLMONS. This sub-genus has been separated by Cuvier from the chsetodons properly so called, in consequence of the peculiar form of the muzzle, which is slender, very much elongated, and has some resem- blance to a whistle. The known species are inhabitants close in shore, and are understood to subsist chiefly upon air insects. ChcEtodon rostratus. This is a very beautiful species, the ground colour being golden and silvery in alternate bands, with an ocellated spot, black in the middle and surrounded with white, immediately in the rear of the dorsal fin; this is the species formerly alluded to as being dexterous in shooting flies. In consequence of the beauty of its colours, and the liveliness of its action, it is often kept in vases by the people of the east, in the same manner as gold fishes are kept in this country. Another species with the muzzle still more elongated, and of a lemon yellow colour with some black spots, has been described as 'inhabiting the South Sea. III. HENIOCHUS — Coachmen. This sub-genus get their common name from one long filament proceeding from the dorsal fin, and sometimes extending to twice the length of the body. The form of this filament is not unlike that of the cord of a coachman's whip. The following is one of the principal species : — Cheetodon macrolepidotus. This is a large species, being sometimes met with of the weight of twenty-five pounds. Its flesh is very much esteemed ; and its colours are brilliant, being very splendent, silvery in the greater part of the body, arid crossed by two brown bands on each side. Several other species of this sub-genus are mentioned by systematic writers, but the accounts of them are not a little confused. IV. EPHIPPUS — Horsemen. The principal charac- ter of these is a deep notch between the spinous and soft parts of the dorsal fin. The spinous part is without scales. This division is found both on the American coast and the east, and the species are very numerous. V. HOI.OCANTHUS. The leading character of these is a large spine on the angle of the gill-flap, the edge of which is also toothed. Like the preceding sub- genus, they are found both in the Atlantic and Pacific. The species is very numerous, their colours are beauti- fully arranged, and they are much esteemed as food. VI. POMACANTHUS. These have the body more elevated, and their dorsal fin rises higher than in most of the species. They have been met with only on the American shores. VII. PLATAX. These have their teeth closely set, the first row being trenchant, and each consisting of three points. Their bodies are very much compressed A -2 C H A F F E R — C H A L C I D I D M. or flattened sideways (hence their name). Their fins are very much elevated and covered with scales, so like the rest of the body, that they seem a continuation of it. There are a few small spines on the anterior edge of the dorsal, and the ventral fins are very long. The height of the fish, seen sideways, exceeds the length. There are several species of them, all natives of the Indian seas ; and they are called sea-bats, and other fanciful names by the sailors. Some of them are found in the Red Sea. CHAFFER. The common English name whereby various species of beetles are called, evidently adopted from the German Kafer, which is, however, employed as synonymous with the whole of the coleopterous insects to which we have applied the name of beetle. In Germany, however, from the great richness of the language, a distinct name is applied to every species of coleoptera ; but in England, owing to the poverty of our tongue, and the small degree of attention hitherto paid to the subject, but very few insects have obtained vernacular names ; and amongst these we find the term chaffer almost exclusively applied to beetles belonging to the Linnaean genus Scnrabceus. Thus the Melolontha vulgaris (Scar abacus vulgaris of Linnaeus) is commonly called the cock-chaffer, whilst the Cetonia aurata (Scarabceus auratus, Linnaeus) has received the name of the rose-chaffer, &c. Of these, the first-named insect is by far the most obnoxious, from its destructive powers, whilst in the larva state, to grass, &c., devouring the roots. As, however, the name chaffer is not exclusively applied to this insect, it will be more convenient to defer its account until we arrive at its systematic place, under the article MELOLONTHID.'E. See also COLEOPTEUA. CHAILLETIACEJ3. A natural order of dico- tyledonous plants, allied to TerebinthacecE, Rosacea, and AquilarinecE, containing three genera, and seven known species. Its essential botanical characters are : calyx persistent, five-cleft, coloured within, with an imbricated aestivation ; petals five, alternate with the segments of the calyx, and arising from the bottom of it ; stamens five, alternate wiih the petals ; anthers roundish ; ovary free, hairy, from two to three-celled ; styles two or three, short, free or coalescing ; fruit dry, two or three-celled drupes ; seeds solitary, without albumen ; embryo thick, with a short, superior radicle, and fleshy cotyledons. The plants belonging to this order are trees or shrubs, with alternate, stipulate, ovate leaves, and axillary white Mowers. They are natives of tropical regions, and are found in South America, and in the islands of Madagascar and Timor. The genera of the order are ChaUlctia, Lciicosia, and Tapura. Chailletia Toxicaria, or rat-bane, is a branching shrub, from six to twelve feet high, which grows on the mountains near Sierra Leone. It bears small white flowers, and yields a fruit the size of a pigeon's egg, which possesses poisonous properties. The kernel is used by the negroes for poisoning rats and mice. In other respects the properties of the order are not known. CHALCEDONY. A mineral much in request in ancient times, and which appears to have derived its name from Chalcedon, a miner who first disco- vered it. Its basis is usually of a semi-opaque character ; and if we may judge from the descriptions given by Pliny and some other of the early authors, it would rather appear that the gems they describe under this name were of a mare beautiful character than those we now employ. There are four woll- known forms of the chalcedony ; the first resembling a common flint, and is usually found in masses of two or three inches in diameter. Under this head we may place the oriental chalcedonies, which are the only ones of any value. They are found in vast numbers on the banks of the rivers in all parts of the East Indies. The second form is of a milky colour, and is of little value. It is principally found in South America. The third form is exceedingly dark and cloudy, and was known to the ancients by the name of smoky jasper. It is at the present time much used in Germany, and worked into the handles of knives. The fourth kind is usually of a yellow or red colour. It comes from the East Indies, and the Italians employ great quantities in the manufacture of their rosaries. The dendritic chalcedonies, or rnocko gems, are much prized as ornamental stones. The arborisations are black, red, brown, or green. The black are the most common, and most distinct ; the red, on the contrary, are rarer, and are less distinct, and are named corallines, from the resemblance of the den- dritic delineations to coral ; and the green are rare, and much esteemed. These arborisations appear in some cases to be owing to iron, in others to man- ganese and iron. Dutens, Von Moll, Daubenton, Blumenbach, and Dr. Maculloch, maintain that many of them are of a true vegetal >le nature. Dutens says, that if the plants contained in chalcedony are extracted, and the fragments thrown on burning charcoal, a bituminous smell is exhaled ; and Von Moll maintains, that chalcedony sometimes contains brown and green moss. Lenz affirms, that the chalcedony found in the amygdaloid of Deuxponts, contains musci of different kinds, such as lichen rangiferinus, confervas, and byssi. And Bliirncnbach says, in a letter to Baron Von Moll, that though he had hitherto disbelieved ;he occurrence of vegetable bodies in the dendritic variety of chalcedony, named mocko-stone, yet he must now admit that it does sometimes contain 3lants, apparently of the nature of conferva. He observed these in specimens from Iceland and Catherinenburg. The same celebrated naturalist maintains, that he found, in the interior of an agate, the fructification of an unknown plant, somewhat resembling the Sparganium erectnm, CHALCIDIDjE. A family of very minute ivmenopterous insects, belonging to the section Pupivora of Latreille, and forming Liunaeus's section Ichnenmones minuti. This family is distinguished )y the wings being almost entirely destitute of nervures, and the antennas, which are strongly ;lbo\ved at the extremity of the long basal joint, are hort, and composed of not more than thirteen joints. These minute creatures are amongst the most erlective agents to be found amongst the insect tribes employed n the parasitic destruction of their larger brethren, he females being unceasingly employed in searching or and depositing their eggs in the bodies of other nsects, almost every order being alike subject to their attacks. It is, however, to the destruction of the arvse of lepidopterous insects that their labours are or the most part devoted. A very common instance of their proceedings may be observed in the chrysalis of the nettle-toitoiseshell butterfly (Vanessa urtica-), which is often to be seen, as it were, bored through with numerous small holes, whence, instead of the CHALK. perfect butterfly, an infinity of minute and beautiful little creatures have escaped. This circumstance seems not a little to have perplexed the old naturalists. How a creature, which ordinarily produced a beauti- ful butterfly, should, at certain times, produce myriads of other smaller insects, was one of those hidden secrets of the creation which they knew not how to fathom ; and we find even the great Swammerdam mentioning it as " a thing very wonderful, that 545 flies of the same species were produced from the chrysalides of four butterflies, so that the life and motion of these four creatures seems to have transmi- grated into those of the 545 others ;" and even the philosophical Ray at first thought that it arose from some defect or weakness in the caterpillar which would prevent the perfect development of the but- terfly ; and therefore, in order that the maxim, " Natura nihil frustra fecit," should not be defeated, she stopped short, and formed them into more im- perfect animals. And in the argument which he sub- sequently used in his admirable work, " The Wisdom of God in the Creation," against the doctrine of equivocal generation, we find the same learned author thus expressing himself: — " You will say, How conies this to pass? Must we not here necessarily have recourse to a spontaneous generation? I answer, No. The most that can be inferred from hence is a transmutation of species. One insect may, instead of generating another of its own kind, beget one of a different. But I can by no means grant this. I do believe that these flies do either cast their eggs upon the very bodies of the fore-mentioned caterpillars, or upon the leaves, upon which they feed, all in a string, while those hatching eat their way into the body, where they are nourished till they are come to their full growth. Or it may be, the fly may, with the hollow and sharp tube of her womb, punch and per- forate the very skin of the ercua, and cast her eggs into its body. The discovery of the manner of the generation of these sorts of insects I earnestly recom- mend to all ingenious naturalists as a matter of great moment. For, if this point be but cleared, and it be demonstrated that all creatures are generated unequi- vocally of parents of their own kind, and that there is no such thing as spontaneous generation in the world, one main prop and support of Atheism is taken away, and their strongest hold demolished, they cannot then exemplify their foolish hypothesis of the generation of man and other animals at first, by the like of frogs and insects at this present day." In what a striking point of view do the arguments of this good man appear, now that it is known that the suppositions upon which some of them were founded so completely correspond with what takes place in nature ; the only part of them not being found to be strictly correct being the idea, that these parasites laid their eggs on leaves which might be frequented by the caterpillars, an idea evidently derived from the general and incorrect principles to which the pre- sence of blight is usually attributed, and to which we have alrea.dy alluded in our article upon that subject. These little animals, of which we probably possess 1500 British species, are highly beautiful in their form, and their colours vie with those of the humming birds. We find gold and purple, copper and green, intermingled in the most elegant order, thus forming exquisite microscopic objects, whilst many of them are highly singular in their appearance. In fact, they appear to be the counterparts of the cercopides amongst the homoptera, possessing, like them, the power of leaping to a very great distance, although their legs are very seldom incrassated. This, how- ever, is the case in the typical genus Chalcis, of which we possess several British species, but which, singularly enough, do not possess saltatorial powers, although their posterior femora are very large. The genera, of which the investigation has been greatly neglected until recently, are very numerous. CHALK. This universally diffused substance is too well known to need any particular description of its external characteristics. We have manifest proofs, in our own country, that this deposit must have experienced very considerable changes in its geolo- gical arrangement by the action of water ; for the vast beds of gravel which are still employed in the formation of roads, &c., have evidently been rounded by attrition, after their separation from the chalk by which they were originally surrounded. In England, chalk ex- tends with little interruption from the coast of York- shire to that of Devonshire, while a series of hills extends from Wiltshire to the coast of Kent ; and a branch from the centre of the latter ranges to the Sussex coast near Brighton. The Isle of Wight basin comprehends the district between Newport and that island on the north, Brighton on the east, and Dor- chester on the west. In Europe, the chalk extends through France and Poland into Russia, and thence to the south of Sweden, is said to occur near the mouth of the Elbe, thence to Flamborough Head in Yorkshire, and thus completing a circuit which may be termed the chalk basin of Europe. Chalk forms, by its extent and distinctive cha- racters, one of the most remarkable mineral features of England. It would seem as if a considerable inter- val of time had elapsed between the completion of the original chalk beds and the deposit of others upon it ; for the surface of the chalk at its boundary with the superincumbent layers, bears marks of having under- gone, during that period, a partial destruction after it was consolidated. There is spread over it a stratum of debris, consisting chiefly of flints washed out of its mass. Moreover, the surface is irregularly worn into numerous cavities, of which many are deep and filled up with the same debris. At the junction of the chalk with the sand and gravel of the plastic clay formation, deep indentations are observed on its sur- face, which are sections of long furrows and cavities, apparently produced by the action of agitated water before it was protected by the covering of clay. The enormous quantity of chalk flint pebbles, completely | rolled and rounded, which are found in the plastic | clay to the south of London, show that the chalk I itself must have been consolidated before that partial | wasting of its upper strata by water. To this hydraulic • action, Cuvier and Brongniart ascribe the irregular 1 furrows and ridges on the surface of the French chalk, j and the Mucdon breccia. The immense scale on ; which this destruction was carried forward may be | inferred from the vast extent of the English pebble | beds. That a long period of time probably intervened between the deposition of the chalk and of its clay coating is rendered probable also by the total differ- ! ence of the organic remains found in the two strata.. The band of chalk which stretches across the east- ern and southern counties of England, from Yorkshire to Dorsetshire, is to be regarded merely as the west- ern edge of a most extensive tract of this formation. Stretching from the Thames to the Don, the chalk C H A M A — C H A M O R C H I S. occupies the interior area of the great central basin of Europe. This concavity is bounded on the north by the primitive mountain districts of Russian Fin- land, Sweden, Norway, and Scotland ; on the west bv the transition and primitive chains of Cumberland, Wales, Devonshire, and Britany ; on the south by the primitive mountains branching from the Cevennes in the centre of France, the Alps, with the various grand groups of Germany, as the Black Forest, the Rhingau and the Vosges, the Bohemian, Thuringian, Saxon, Silesian, and Carpathian mountains ; on the east by the Ural chain and its branches. The chalk does not rest on the mountains themselves, but within the area which they circumscribe at a certain distance from them, an interior area may be traced, over which the substratum of chalk is believed to extend. Cuvier and Bronerniart represent the chalk deposit as forming a sterile soil, and adduce Champagne as a proof of its being in some cases uninhabitable. In our own country the population of the chalk district is certainly less dense than that of many other parts, but it is usually habitable, and to a certain extent productive. Indeed we may say that the chalk valleys are often in this country extremely fertile, of which the Kent and Surrey hop grounds, and the downs for pasturing sheep, afford examples. Beech is the tree best fitted for a chalky soil. The Chiltern Hills, in Oxfordshire, were anciently covered with woods and thickets of beech, which afforded harbour to banditti. The lower beds of the chalk formation are, with few exceptions, filled with water, which percolating from above is arrested by the subsoil of blue clay. Thus are formed the springs and rivulets which issue near the foot of almost every chalk hill. It is remarkable that America, both South and North, seems to be destitute of chalk, Mr. Maclure asserting positively that it does not exist on that continent. Chalk is well known to have an earthy dull fracture, but it occasionally concretes into a hard limestone. This compact chalk has been used in building. As tins formation is composed throughout of a series of homogeneous beds of a tender earthy limestone, it does not admit of stratiform sub- divisions. But the numerous beds of nodular flints, which lie alternately distributed through the greater part of its mass, form one of its most curious and essential fea- tures. They are constantly present in all the upper portions of the formation, but are frequently absent in the lower ; affording a criterion by which the two may be distinguished. Hence the meaning of the terms upper and lower chalk. The uses of this mineral are various. The more compact kinds are employed as building-stones, when they are used either in a rough state, or are sawn into blocks of the requisite size and shape ; it is burnt into quicklime, and used for mortar in different countries ; it is also employed in great quantities in the polishing of glass and metals, and whitening the roofs of rooms in the state of whitening ; in constructing moulds to cast metal in ; by carpenters and other artisans to mark with. When perfectly purified, and mixed with vegetable colours, it forms a kind of pastil colour ; thus, with litmus, turmeric, saffron, and sap-green, it forms durable colours. The Vienna white known to artists is perfectly purified chalk. It is also used by starch-makers and chemists to dry precipitates on, for which it is peculiarly qualified, on account of the remarkable facility with which it absorbs water. CHAM A. Lamarck, in constituting this gcuus, has separated from the Linnaean arrangement al.1 such shells as have only a thick oblique transverse tooth, resembling a lengthened callosity, in general crenulated or grooved, fitting into a corresponding cavity in the lower valve. The shell is inequivalve, irregular, heavy, rough, scaly, or spinous, having the faculty of affixing itself to other bodies, or to each other in groups, by means of its lower valves. The apices are unequal and recurved ; valves with two distinct distant lateral muscular impressions; ligament external and inserted. The characters of these shells, in some respects, ally them to the genus Die-eras, and in others to the genus Etkerut. They are, most of them, elegant shells, some with delicate waved or foliaceous valves, some with spines, and pleasingly coloured with yellow, pink, and brown. The animal possesses a suborbicular body, terminated on the upper side with a sort of hook-mantle slightly opened, the foot terminated at its extremity by a portion much narrower than the base ; the superior lobes of the branchia very short. The following subdivision of this genus, though not exactly in unison with those of Lamarck, appear to us natural and well defined : — 1st, The species that are irregular, inequivalve, with- out lunulae, adhering by the left and largest valve-, the two summits turning more or less in a spiral form, the left summit more prolonged than the right, as in the Chama Lazarus, and in the same division, those whose summits are prolonged nearly equally, as in the C. gryptundes. 2nd, The species subequivalve, sub- regular, with a distinct lunula, the summits but slightly spiral, adhering by either valve, as in the C. arcinella. 3rd, The species which are subregular, half-heart shaped, very inequivalved, the right valve much excavated, the left valve operculated, one conical cardinal tooth, smooth on one side, and fitting into a deep groove on the other valve ; ligament as if double, the internal portion much thicker than the external, the muscular impression anterior and very long, as in the Chama hemicardium. This genus is extremely difficult to characterise by any system of teeth or hinge, for each species presents a particular modification, nevertheless, the last division named is so peculiarly different from the others, that without any reference to the animal, it might well form a distinct genus. These shells are found in all the seas but those of the north ; in the southern seas they are more numer- ous than elsewhere. Eight or ten species are known in a fossil state. They are classed in the third class, Acephalopftora ; third order, Lamcllibranchiata ; seventh family, Camacea. CHAMvEROPS (Linnaeus). A genus of palms, commonly called the fan-palm. Linntean class and order Polygamia Diaecia; natural order Palnue. (ie- neric character : flowers polygamous ; spatha double, leathery, interior side bursting obliquely ; florest sitting and bractiate; calyx three-cleft; corolla of three petals ; filaments dilated at the base, and con- nected; stigma three, awl-shaped ; berries three, one- seeded. This palm thrives best in sandv loam, and requires moist heat. It is found in the south of Europe, and all warm countries. CHAMORCHIS (Richard). A single plant forming a new genus, formerly called Opkrys Alpina by Linnaeus. Like other orchises it has tuberous roots, which are liable to be lost if not planted in turf, and kept in a station like their natural one. CHAMPACA — CHARADRUS. CHAMPACA. The specific, as well as the Malayan name of the Michdia, found at Malacca ;md other places in that part of India. It is a lofty ti in her tree, and highly ornamental from its numerous yellow flowers, with which the spray is covered in autumn. It belongs to Magnoliacece. CHARACEAE— Chara family. A natural order of acotyledonous or cellular plants, containing one or two genera, and upwards of twenty species. They are aquatic, leafless, submersed plants, consisting of a central axis, from which proceed numerous whorled branches. The axis is composed of parallel tubes, which are either transparent and flexible, or encrusted with calcareous matter, so as to become opaque and fragile. The branches, or leaves, as they used to be called, are smaller tubes of a similar nature. The organs of reproduction in this family of plants are very obscure, but, according to the most recent observations, they appear to be of two kinds. 1. Globules, of a reddish or orange colour, the coats of which are composed of triangular scales, which are at first nicely fitted to each other, and afterwards separate, when the plant reaches maturity. On the margin these scales consist of numerous parallel, colourless, hollow tubes, containing minute orange-coloured bodies, analogous to the sporules of other cryptogamic plants, which are easily dispersed whenever the globules are in any way injured. It ie to these little bodies that the globules owe their colour. 2. Minute, sessile, spirally striated, ovate nucules, which are enveloped in a membrane, have frequently five projecting points at the apex, and are filled with minute granular bodies at first distinct, but afterwards coalescing, and giving rise, when they germinate, only to a single plant. These two sets of organs, the globules and nucules, which are found either upon the same or different plants, were long looked upon, even by botanists of the first eminence, such as Linnajus, Jussieu, Decan- dolle, and Brown, as being true stamens and pistils. Hence the plants were placed in the phaenogamic or vascular division of vegetables, and were referred to the classes Monandria and Atoncecia. The structure and habits of the characea?, however, seemed to differ so much from those of the true flowering plants, that doubts were for a long time entertained as to the propriety of referring them to that division of the vegetable kingdom ; and a more careful examination has led most botanists to believe that they ought to be considered a distinct order of cellular vegetables. In consequence, however, of the peculiarity of their organisation, it is not easy to trace their affinity to other cryptogamic tribes, and considerable difference of opinion at present exists on the subject. Professor Lindley considers them as allied to Conferva;, but has placed them amongst the Musmidece, or moss-like plants ; while Dr. Hooker, has placed them beside the Alga or sea-weed. The chara tribe are remarkable on account, of many of the species emitting a very disagreeable fetid odour, which does not seem to be dependent on the water in which they grow. They are generally of a dull greenish colour, and have roots, which are usually attached to the bottom of stagnant pools of fresh or salt water. Their stems are delicate, slender, and sometimes jointed. They are frequently rendered hard and britilc by encrusta- tions of carbonate of lime, which are funned >n tin- outside of the central tube, and are covered by a fine transparent membrane. These encrustations are not mere accidental deposits, depending upon the presence of some extraneous matter in the water in which the plants grow, but are formed by the vital energies of the plant, and probably perform an important office in the processes of vegetable life. The particles ot calcareous matter, when carefully examined under a high magnifying power, exhibit various beautiful arrangements, at one time extending in the form of parallel lines along the stem, and at other times forming oval groups, which are attached to each other like the beads of a necklace. While examining these in the Chara vu/garis and hispida, Sir David Brewster found that the plants became phosphorescent when placed on heated iron, so as to display their entire outline in the dark. He also ascertained that each mass of calcareous matter consisted of minute particles, which possessed double refraction, and had regular neutral and depolarising axes. An important and highly interesting physiological phenomenon has been noticed in some of the chara family by Professors Amici and Blainville. On examining the steins of some of the species, more especially the Chara vu/garis, they observed two liquid currents, one ascending, the other descending, cir- culating in the same tube, without being separated by any partition which could insulate them. The reality of this phenomenon was completely confirmed, by their observing distinctly that certain molecules of one of the currents, being attracted by the other moving in an opposite directing, were sometimes carried along with it. The rate of motion is stated to be about two lines in a minute. The motion is stopped by pressure, laceration of the tube, or by the application of a drop or two of brandy. The characeae are met with in all regions of the globe, in Europe, Asia, Africa, and America, but they are most abundant in temperate countries. Some of the species found in Iceland are said to grow even in the hot springs of that island. Nucules of charas, under the name of Gyrogomits, are found in the marl deposits of the Forfarshire j lakes, and in the chalk of Montmartre. From these i fossil remains, it would appear that the characeae were formed more recently than the ferns and palms. Trout are said to thrive well in water where charas ' grow, probably on account of these plants attracting a great number of insects. The characea3 do not possess any particular known properties which would render them useful either in a medical or economical point of view. The only genera of the order are Chara and Nitclla. The latter genus is said to differ from chara in being always transparent, and free from calcareous matter, in having a single-jointed stem, and the globules and nucules on separate plants. These characters are, however, by most botanists not con- sidered sufficiently constant, and the two genera are therefore generally described under the common name of chara. There are eight species natives of Britain, and of these Chara transluccns is the largest and brightest coloured. Chara vulgaris, from its roughness, is used, like some species of equisetum, for scouring or polishing. CHARADR1US — Plover. A very interesting genus of birds, belonging to the order GralMae, of which the details will be found under the article PLOVEK. 8 CHARICLEA— CHEESE-HOPPER. CHARICLEA (Stephens). A beautiful genus of lepidopterous insects belonging to the family JVbc- tuidte, and having for its type the rare peach blossom moth of British collectors, Noctua Delphinii of Lin- naeus. The anterior legs are armed at the extremity of the shanks with two shining horny spines ; the wings are very gaily ornamented with purple markings, and are about an inch and a quarter in expanse. CHARLOCK is the English name of the Sinapu arvensis of Linnseus. It is a tetradynarnous annual, and belongs to the natural order Cruciferee. No weed, except the thistle perhaps, gives the English farmer more trouble, nor causes more injury to his crops, than this. It springs up with, and ripens seed before the corn ; consequently much seed is scattered on the ground by the sithe and sickle in gathering the crop. Although an annual, it is not easily extir- pated, as the seed will lie uninjured in the soil for years ; and when the farmer has lost sight of it for several consecutive seasons, it will at last come up so abundantly, that the crop of corn will be choked by the plant, and covered with the yellow flowers of the charlock. CHARLWOODIA (Sweet). A genus of orna- mental trees, natives of New Holland and New Zealand, named in honour of G. Charlvvood, F.L.S., an intelligent English botanist. Linnaean class and order Hexandria Monogynia; natural order AsphodelecE. Generic character : calyx bell-shaped, regularly six- cleft, withering ; stamens inserted in the throat of the corolla ; filaments awl-shaped, smooth ; anthers versatile, cleft at the base ; style filiform ; stigma three-lobed ; berry globular, three-celled ; cells full of seeds. There are four species described ; two are common in our collections, "one with pale purple, another with blue flowers ; they should be kept in a very warm greenhouse, as they are tender, or in a cool part of a stove, and may be increased by cuttings of the young side shoots. The cuttings must not be deprived of their leaves, but put into pots filled with an equal mixture of light loam, moor earth, and sand ; which compost is also the best soil to grow them in." Sweet. CHAR^EAS (Stephens). A genus of lepido- [>terous insects belonging to the family Noctuidce, laving the wings more or less notched ; the palpi are very short, and the antenna; of the males more or less comb-shaped. The genus includes five British species which vary considerably in structure, amongst which the Pkalcena bombyx graminis, Linnaeus, or the antler moth, is placed. This insect is exceedingly destructive in pastures, feeding upon grass ; and it is recorded that in Sweden, towards the middle of the last century, its ravages were so extensive that whole meadows appeared white and dry, as though a fire had passed over them. In England also, at various but uncertain periods, different parts of the country, especially the northern counties, have suffered from its ravages, " spots of a mile square were totally covered by them, and the grass devoured to the root." Mr. Wailes has recently published some interesting observations upon this insect in the Ento- mological Magazine, noticed upon Skiddaw : at least fifty acres of which were so completely devastated and the line of devastation so clearly marked, that even from the town of Keswick the progress of the larvae down the mountain could be distinctly noted. Vast quantities of rooks flocked to the spot to feed upon the delicious repast afforded by these caterpil- lars ; but so greatly was the vegetation destroyed, that even several years afterwards the extent of their ravages was distinctly visible. " Of course." adds Mr. Wailes, " the qnality of the newly-grown herbage was materially improved, thus affording another in- stance of indirect advantages derived irom insects ;'' and Mr. Haworth in like manner observes, " Perhaps this apparently destructive scourge of the Swedish pastures (though happily not of our English ones) is of more use in the great economy of nature than we are aware of, by preventing the almost total suffoca- tion and consequent destruction of the flowering plants, in giving them an occasional season in which they may recover themselves to become the food, the necessary food perhaps, of many insects, &c., which would perish whenever that became extinct." The caterpillar is of a brown colour with yellowish streaks on the sides and back. In the month of June it changes to a shining brown chrysalis, and the moth appears in about a fortnight, being of a brown colour, and having a long pale line along the upper wings united to two large pale spots in front, and branching behind into three oblique teeth. We have, however, met with it later in the year, having captured it at the middle of August, both upon the Wrekin in Shrop- shire and Snowdon. It seems indeed to frequent mountainous districts, and contrary to the general habits of the family, we noticed it flying with great velocity in the middle of the day. We mention this because Mr. Wailes has stated some curious facts to which it is opposed. He noticed these insects one morning, about eight o'clock, flying in swarms over old pastures ; on returning to the spot, a couple oi' hours afterwards, with his fly-net, not one was to be seen. The next morning, however, he was early on the spot, but then also not a solitary moth was to be seen ; at half past seven he was about to return, " when suddenly the whole field, as far as the eye could reach, was once more the scene of their gam- bols, the eye became bewildered with their motions, they were lost in the mazes of their evolutions. Sudden, however, as their appearance had been, their disappearance was equally so, as with one general consent at about half past eight they again settled, and their flight for the morning being over, scarce a soli- tary specimen was any where to be seen. The moths flew about three or four inches from the ground, and apparently very seldom alighted, but threaded their way most dexterously amongst the long culms of the grasses." CHAULIODUS. A genus of soft finned fishes with abdominal fins, belonging to the pike family. There is only one known species, an inhabitant of the waters of America, it is of a bright green colour, and about a foot and a half long, the muzzle is very short, but the gape extends as far as the eyes, and the teeth are strong and powerful, especially two crooked ones in each jaw ; its habits, and, indeed, its characters are very imperfectly known. CHEESE-HOPPER or CHEESE MITE. A small white fleshy grub of an elongated form, ofim found in decayed cheese, and which is the larva of a pretty two-winged fly known by the systematic name of Piophila (Tyr&phaga, K.) casei. Of this insect the immortal Swammerdam has left us an interesting account, and although to unthinking persons it may appear to be a frivolous subject of inquiry, we find this illustrious philosopher affirming " that the limbs and other parts of this worm are so uncommon and C H E I L O D A C T Y L E S — C H E 1 R O P T E R A. elegant, and contrived with so much art and design, that it is impossible not to acknowledge them the work of infinite power and wisdom to which nothing- is hid, nothing impossible." It has been a common error that these insects were bred spontaneously from the cheese, and epicures accordingly do not hesitate to eat them with great goiit, thinking them formed from the best part of the cheese, whereas they are produced from eggs deposited therein by the parent lly. These larvae are long, cylindrical, and composed of twelve rings, the first of which is furnished with two small bent hooks of a black colour, which serve not only as teeth, but for feet also, the insect having no other organs employed as legs. The terminal segment of the body is covered with a variety of pro- minent tubercles and little cavities like wrinkles, of which we shall presently see the use. In our article CERCOPID.* we have alluded to the leaping power of this insect, and our figure will give an idea of the manner in which it prepares to make a spring. 1, the cheese-hopper preparing to spring. •2, the insect's natural size. 3. 4, the fly to which it is transformed : natural size and magnified. When this larva prepares to leap it first erects itself on its anus, in doing which it is greatly aided by the prominent tubercles of the terminal ring, which enable it to maintain an equilibrium. It then bends itself into a circle, and having brought the head towards the tail it stretches out the two hooks of the mouth, fixing them into the two cavities at the extremity of the body. It then contracts the body from a circular to an oblong figure, the contraction extending in a manner to every part of the body. It now suddenly and with very great violence lets go its hold, the noise produced by its hooks being very perceptible, and in this manner the leap is effected, being in fact similar to the mode employed by the salmon when they wish to pass over a cataract or salmon leap, as it is termed. Swammerdam saw one, whose length did not exceed a quarter of an inch in length, leap out of a box six inches deep, that is to a height more than twenty-four times greater than the length of its own body, but they will leap much higher. Here we cannot but admire the powers given by nature to j different creatures, and their limitations, to answer different purposes, and not for mischief to mankind. If for instance a power of motion, proportionally equal to that possessed by this insect, had been given to the serpent tribes, how much more terrible would they not have been rendered then, than they are with their present capabilities? A viper would throw itself nearly a hundred feet upon the traveller, and the rattle-snake several hundred. Swammerdam, after giving a minute account of the external and internal anatomy of this creature, observes, " Now let the sharpest geniuses, and men of the greatest pene- tiation and learning, judge if a creature on the fabric of which there plainly appears so much art, order, contrivance, and wisdom, nay, in which is seen the hand itself of the Omnipotent God, could possibly be the production of chance or rottenness." The female fly is provided at the extremity of the body with a very fine retractile borer wherewith she pierces the cheese, and is thereby enabled to deposit her eggs in the wound thus made. Shortly after \\hich the grubs are hatched, and feeding upon the cheese cause it to decay ; the fine powder which we perceive, and which is so highly prized by the gourmand, being nothing else but the excrement of these grubs, which, when they have acquired their full size, desert the cheese, and in three or four days they lose all motion, grow stiff, become hard, and contract their bodies into an oval mass not more than half their previous length, within which the real pupa is inclosed, this insect undergoing the coarctate kind of metamorphosis, like the majority of dipterous insects. Alter remaining some time in this state, the chrysalis becomes of a black colour, and the inclosed nyrnph breaks that part of the outer covering \\ hich defends its head into two parts, and at the same time throws off from every part of the body a thin and slight membrane which it leaves within the old case. At first the wings are scarcely perceivable, the insect, however, runs about very quickly, and shortly afterwards the wings are by degrees extended until they assume their full size, when the insect is fitted for pursuing its duties, which almost entirely consist in the reproduction of the species. The fly is about the size of the common domestic fly, of a shining blackish green colour, the wings transparent and shining, and the legs varied with ochreous and black. CHEILODACTYLES. A genus of spitious finned fishes, belonging to Cuvier's third family Scein- o'ides, and bearing some resemblance to the perch family. They have the body oblong, the mouth small, numerous spinous rays in the dorsal fin, and the infe- rior rays of the pectorals continued in a membrane. There are several species, the greater number of which are inhabitants of the eastern seas. CHEILODIPTERA. A genus of spinous finned fishes, belonging to the perch family. They are all of very small size, and found in the warmer seas of the east. CHEIMATOBIA (Stephens). A genus of lepi- donlerons insects, belonging to the family Gcometridfe, and remarkable for their appearance in the winged state in the depth of winter. Of these the type is the Phal. geom. brumata of Linnaeus, an insect of very plain appearance, measuring about an inch in expanse, of an ashy brown colour, with nearly obsolete darker waves. It is very common in the neighbour- hood of London, and may be seen flitting about the leafless hedges at dusk or by lamp-light, in moderate weather. CHEIROPTERA— winged hands. The first family, or sub-order, of Cuvier's groat order Carnaxsiert, or mammalia, which feed upon animal matter. Their most remarkable characters, and the one from which they obtain their name, is that ot'having the extremities, the arms especially, furnished with membranes, by means of which the animals are enabled to fiy ; although, in a manner much more awkward than that of birds. A particular account of the action of those singular creatures, as well as of the habits of the lead- ing species, has already been given in the article BATS. Hence it will be necessary, in this phw, to 10 C H E L I F E 11 1 D K — C H E L O N E. give only a synoptic table, for the sake of reference to the different genera. There are two tribes in the family, the bats properly so called, and the Hying bats and the first admits of sub-division into two groups. FIRST TRIBE. — Bats properly so called. First group, chiefly animal feeders. Genus 1, Vampires. Teeth; incisors £, canines \ grinders f. Canines in lower jaw angular, roots touching. Genus 2, Phyllostoma.

In the above tabular statement, the whole of the incisive and canine teeth arc mentioned, but only half the grinders, or. those on one side of each jaw, the upper number referring, in all the statements, to the upper jaw, anu the under number to the lower. CHELIFERIDiE. A family of small annulose animals, belonging to the class Arachnida, and to our order Adelarthrosomata, having very much the ap- pearance of minute scorpions destitute of tails, the body being oval, depressed, and narrowed in front ; the palpi as long or longer than the body, in the form of arms, each terminated by a double claw ; the logs are of equal size, and shoit, being terminated by two hook?, and the eyes (two or four in number) are placed at the sides of the tliorax ; the breast is not furnished with the remarkable toothed appendages to be observed in the scorpions. These animal*, brinii destitute of lungs, breathe by means of lateral trachea; or spiracles along the sides of the body. By Linnuiiis the only species of the family known to him, was at first arranged with the rnites (Acarus), and afterwards with the harvest-men (Phalanghan), from all of which however it is abundantly distinguished, and accord- ingly Geoffroy established for its reception the genus C/iclifer, whilst Fabricius placed it amongst the scorpions. Illiger again, neglecting the step taken previously by Geoffroy, formed the genus Obisium for this group ; and still more recently Dr. Leach has not only adopted the genus Chelifer of Geoffroy, but also that of Obisium for several of the species which differ from the true chclifers in some respects, a step which appears to us to have been improperly taken, as it is evident that Illiger's genus was strictly synonymous with Geoft'roy's, both having the Cliclifer cnncroidcs for the type. As a family, these little animals are highly inter- esting in respect to the general distribution of the class to which they belong, exhibiting, as they do, the appearance of one group, whilst they in reality belong to another quite distinct. They are found, in general, in moist situations in moss under stones, flower-pots in gardens, and in unfrequented parts of buildings ; they also get into old books, herbariums, &c., where they feed upon other more minute insects, such as Atropos lignarius, acari, and occasionally even venturing to attack the domestic fly, of which circum- stance various notices will be found in the Magazine of Natural History. We have likewise captured the largest species, which we have hitherto seen of the group, under the bark of trees in Windsor forest, in the act of devouring even the hard-cased beetle (Bitoma cretiata}, Goetze also has fed them with aphides. According to Linneeus, these animals occasionally introduce themselves beneath the skin, producing a painful swelling, and on the information of Dr. Bcrgius, he states that a peasant had his thigh pierced during the night by one of these insects, which formed by the morning a pustule of the size of a nut, which was very painful. These insects creep rather quickly, and will, when disturbed, run sideways like a crab. Roesel states that the female lays small eggs, of a greenish-white colour, which she forms into a mass side by side, and, according to the elder Hermann, she carries this mass about with her be- neath the body, like some spiders. The family comprises only the two genera men- tioned above, of each of which there are various British species. The type of the family, Phalangium cancroides of Linnaeus, seldom exceeds one-eighth of an inch in length. CHELONE (Linnaeus). A genus of American ornamental perennial herbs, of late years introduced into our flower gardens. Linnaeaa class and order Didytiamw. angiospermia ; natural order Scrophularia. Generic character: calyx five-parted, persisting; corolla bell-shaped, bellying, limb two-lipped, the upper one two, and the lower three-fobed ; sta- mens, rudiments of five, smooth or bearded ; anthers ncumbent and oblong ; style bearing a headed or bilamcllated stigma; capsule two-celled, two- valvcd ; margins of the valves inflexed ; seeds mar- rinated or naked. The chelones are pretty showy C H E L O N I A. plants, and all grow freely in any f course assists them in making their way through he water. This genus contains seven or eight known pecies, of which we shall mention only some of the more important. CHELONIA MYDAS, common green Turtle, or eat- ible turtle. Of all the chelonian reptiles, this is de- ervedly held in the highest esteem, from the very lourishing and palatable food which it affords to the luman race. It is also one of the largest of these ribes, and it is not less interesting from its habits and manners, than from its utility as an article of diet. A full-grown turtle often measures six or seven eet in length, from the nose to the tip of its short ail, three or four feet in breadth, and nearly as much n thickness at the middle of the body. It sometimes weighs eight hundred pounds. The body appears of an oval form, and the head is of considerable size in proportion to the body. The tail is short and thick. The feet are long, and much better adapted to the iction of swimming than that of walking. The head, feet, and tails, are covered with scales. The breast ilate is shorter than the shield, and has twenty-three r twenty-four plates disposed in four rows. The prevailing colour of this turtle's shell, when in its usual situation, is bright brown, with spots of a yellow colour, and when the shell becomes dry, the brown sumes a darker hue. This species frequents the coasts both of the islands and continents of the inter-tropical regions, and is found in great abundance both in the East and West Indies. It sometimes enters the months of large rivers, and occasionally goes to some distance from the shore, into the sheltered woody parts of the coun- try. It swims with great facility, keeping its head and part of its shell above the surface of the water ; but when it fears the approach of danger, or seeks its prey among the rocks, it dives to the bottom, and may be seen browsing at its ease among the weeds. It is said, however, that it does not dive very readily, as the specific gravity of its body but little exceeds that of the salt water. When it quits the water, its motion on the land is rather a scramble than a walk, and resembles that of seals and walruses among quadrupeds, except that it is much slower. The great purpose for which turtles go on shore is to deposit their eggs in the sand. This process is generally begun in the month of April, and takes up several week?, as the eggs are laid at intervals of about fourteen days. When preparing to lay her eggs, the female turtle digs a hole about two feet deep, a little above high-water mark, and into this cavity she drops about a hundred eggs at one time. Wrhile thus employed, her attention is so completely taken up with the business for which she has come on shore, that a person may easily approach her from behind and catch the eggs as they are let fall ; but if disturbed before she begins to lay, she quits the place, and seeks a more secluded spot. After having depo- sited all the eggs which she is to lay at one time, she scratches the sand over them, and leaves them to be hatched by the heat of the sun. The eggs of this species are round, about the size of a tennis ball, and covered with a white skin resembling parchment. It is said that that part of turtles' eggs, which is analo- It C II E LO N I A gous to the albumen or white in the eggs of birds, does not coagulate by the heat of boiling water. As the female turtle lays her eggs at three or four times, with intervals of about a fortnight, the young are of course hatched at different periods, the eggs of each laying require about three weeks before the young are ready for extrusion. The little animals are of the same shape with their parent, but have only a soft covering instead of a shell. As soon as they are released from their confinement, they make directly for the water ; and though this be sometimes at a considerable distance, they shape their course to- wards it in a straight direction. But a small propor- tion of them, however, in general reach their natura habitation, Great numbers of them are seized by various predacious animals, especially cormorants and other large birds, which hover about the shore from Mav to September, for the purpose of seizing such a desirable prize. The individuals of this species are often found col- lected into numerous groups, though it does not appear that they have much enjoyment ot'a social intercourse, but are rather attracted to tlnj saint; place by the abun- dance of their natural food which it alFords. During the coupling season the male and female seem warmly attached to each other, and are said to continue together for near a fortnight. To what age the green turtle is capable of living, were it to remain unmolested, cannot be ascertained ; but it is conjectured, by those naturalists who suppose the age of an animal to depend upon its size, and the number of years required for attaining its full growth, that this species must live for at least a century. We shall see hereafter that this is no uncommon age for species of a much more diminutive size. Even in the time of Pliny, the taking of turtles for the tables of the great was practised in the East Indies ; and if we may credit the accounts of ^Elian and Diodorus Siculus, the barbarous nations of the East were accustomed to employ the shields of the largest individuals as canoes. It is believed that it is only within these hundred and twenty years that turtles have been imported into Europe for the purposes of food. Various methods are resorted to in different countries for catching turtles. A very common mode is, to watch them as they go on shore or return during the season of laying their eggs, when they are easily arrested, and, by the united force of several persons, are turned on their backs, a position from which they find it extremely difficult to escape. Several individuals are thus turned, and when a sufficient number has been thus partly secured, they are dragged away by ropes, and carried in boats to their place of destination. This is the method prac- tised by the inhabitants of the Bahama islands, and is often employed with success by sailors while touching at the islands between the tropics during their long voyages. Turtles are also taken while swimming in the sea. Some fishers of great dexterity dive for such as they see at the bottom in the shallows, and, getting on their backs, press down the hind part, and raise the fore part of their body, so as to compel them to rise to the surface, wrun an assistant is ready to slip a noose over the head, and thus secure the captured animal. The most common mode, however, of catching turtles out at sea, is by means of a kind of spear, or harpoon, with a long wooden shaft, to which the head of the spear is but loosely attached. This kind of fishing, as it is termed, is generally carried on by two men in a small light boat or canoe. One of those persons manages the boat, while the other stands ready to dart the spear into the back of his destined victim. It is not long before a turtle is seen either swimming at the surface, or, what is more usual, feeding at the bottom, when the water is about a fathom deep. Sometimes the animal discovers the approach of his enemies, and endeavours to escape, but the men paddle after him, and generally contrive to tire him out in about half an hour's chace. The spearman then hurls his weapon, the head of which, from the peculiar con- struction of the instrument, generally sticks fast in the shell, while its attachment to the shaft is secured by a long string. The animal, thus wounded, again makes oft', unless he has been so much fatigued in the chace as to be incapable of further exertion. In either case he soon becomes an easy prey to his pursuers. It is only for its flesh that this species is so much esteemed, its shell being of no use. In many of the West Indian islands turtles are exposed in the open market, and a turtle-steak is there as common as a beef-steak in Britain. The flesh of the turtle is extremely nutritious, and is considered an excellent restorative in cases of debility and emaciation. Green turtle are perhaps the most delicate, and certainly the mildest in their manners of the whole genus. They are, strictly speaking, inter-tropical animals, being rarely, if ever, found beyond the 20th degree of latitude in either hemisphere. Within their range, however, they are very plentiful, and afford an abundant supply of food to even the rudest tribes. The New Hollanders, in the northern parts of that island, which lie within the turtle latitudes, are very dexterous in the capture of them. For this purpose they make use of barbed pegs of very hard wood, which are loosely placed on the end of a pole of light wood of considerable length. This poie is made a little thick at the end, over which a loop of string is passed, the other end of which is firmly attached to the peg. This they throw as a spear, in the use of which they are extremely dexterous, and the peg, taking effect in the cartilaginous covering of the turtle, remains firm there, while the long handle disengages from the peg, but remains attached by the thread, and acts as a float which keeps the turtle close at the surface, so that they can paddle after it till it is completely exhausted, and so capture it with very little trouble. On the north-west coast of he same island, where the land is almost, or alto- gether barren, and no inhabitants have hitherto been seen, turtle come to the banks in great numbers for the purpose of depositing their eggs, and are cap- tured by turning them on their backs, in the same manner as is practised at Ascension, in the South Atlantic, and at the Gallipagos islands, on the west :oast of America. It should seem that volcanic formations, and also oral reefs, have some peculiar attractions for these animals ; and it is natural to suppose that they should, inasmuch as these are the elements of much greater fertility for those marine plants upon which .urtle feed, in both of these, than those are in more earthy formations. Volcanic matter always contains a considerable proportion of salts or alkalis, and there s a good deal of animal matter in the substance of C H E L O N I A. 1A :he coral reef. These substances not only act us i the Atlantic coasts of America, but is said not to he manures to the sea-weeds, but they serve to combine the earthy particles more firmly together, and thus a firmer hold is given to the vegetation. This is so remarkable, mote especially on the reefs, that, after the lapse of a year or two, substantial rock, with thick vegetation upon it, may be found in places where the deep sea line could previously find no bottom. met with in the South Sea. Though so much smaller than the green turtle, the hawk's-bill possesses considerable strength ; and when attacked, defends itself with much ferocity, giving very severe and painful bites. It is also more difficult to secure, as its shield is more convex, and its feet longer than those of the first species ; so that when turned on its back, it more readily regains its natural position. The female begins to lay her eggs in May, and continues, with intervals, till July. She is said not to deposit, them in fine sand, but in gravel mixed with shells. The young of this species very nearly resembles those of the former. The eggs of the hawk's-bill turtle are esteemed very delicious ; but its flesh is unwholesome, and affects those who eat of it with fever and dysentery. It is almost entirely for the plates of tortoiseshell that it is made an object of search. The use of tortoiseshell was known to the ancients, but it is only in modern times that the manufacture of it has been brought to perfection. In selecting the dnced, sharp at the terminations, and incurvated so as plates, those are preferred which are thick, clear, and to have some slight resemblance to the bills of birds transparent, and variegated with dark brown, golden of prcv, and it is called, par excellence, the tortoiseshell j yellow, red, and white. In preparing them for use, • , • P . 1 ' _ ! j.1 iil CM. A I . I 1. /• 1* 1.1 Chcltmia caretta, the hawk's-bill, or tortoiseshell turtle. The name of hawk's-bill is given to this species from the form of the jaws, which are pro- turtle, because it is from this species that the fine tortoiseshell used for so many ornamental purposes in the arts is obtained. The plates or shells of some the plates are softened in warm water, and then re- duced to the desired shape, by pressing them in warm iron moulds. After they are cooled, they are taken till cool and dry. It is usual to place below them metallic leaves of such a colour as it is wished should appear through the transparent part of the shell. In the Indian and Chinese seas the hawk's-bill turtle others are occasionally used, but they are very infe- ', from the mould, smoothed and polished. For the rior both in colour and lustre, and thus they are purposes of inlaying in cabinet work, the moistened employed only as veneers, through which a coloured plates are pressed perfectly flat, and kept in that state ground may be si-en. The hawk's-bill turtle, though of considerable si/e, is much less than the preceding, tin- largest indivi- duals seldom weighing more than three or four hun- dred pounds. The shield is of an oval, and almost ! ;s very plentiful ; and it forms one of the principal heart-shaped form, slightly sinuated before, and narrowest behind. The disk is covered with thirteen plates, that are two or three lines thick, of a smooth surface, nearly transparent, lying over each other like tiles upon a roof. The five vertebral plates are of unequal si/.e and figure, though each is ridged longitudinally in the middle. That nearest the head is very large and quadrangular, with a semi-circular margin anteriorly. The three next plates are hex- objects of the Malay fishery, which is carried on through all the eastern archipelago, and along the north-east coast of Australia. As this species is valuable only on account of its shell, it is not sought alter except by nations which carry on trade ; and, indeed, the capture of it requires a little more dex- terity than that of the eatable turtle. It. is also very abundant in many parts of the AVest Indian seas, moie especially in the gulf of Honduras, where great nuin- agonal, and have their greatest length across the \ bers are captured. It is sometimes said, that the shell body. The fifth is pentagonal, with one angle directed is inferior in the western world to what it is in the backwards, and a little prolonged towards the tail, eastern; but it does not appear that there is much The eight lateral plates are very large, and of an irregular pentagonal figure. There are twenty-five marginal plates, which are so much imbricated as to give the sides of the animal a serrated appearance. The colour of all these plates is generally black, with irregular transparent shades of red or yellow — all of them together sometimes weigh from four to eight pounds. We have been thus particular in describing the plates of this species, because they constitute its most valuable product. They form what in Europe is denominated " tortoiseshell," but which, by the in- habitants of the West Indies, is more properly called " turtleshell." The head and neck of the caret turtle are considerably longer than those of the green turtle, and the upper mandible projects so much over the lower, as to give the snout a distant resemblance to the bill of a bird of prey, whence English sailors havo given it, the name of hawk's-bill. This species is found in the Asiatic seas, and on truth in the saying. Chclonia Caouanna, the loggerhead turtle. This species is much more discursive than either of the two former, and also occurs in higher latitudes. Its colour is more or less of a reddish brown ; five plates in the middle of the shield have an elevated crest in the centre ; the point of the upper jaw is curved ; and the legs are much longer and straighter than in either of the two former species. It is a powerful animal, and very energetical in all its actions. It is a large species, and is said sometimes to ex- ceed the green turtle in size. Its head is much larger in proportion than that of either of the former species. The mouth, and especially the upper mandible, is also of considerable size. The neck is thick, and covered with a loose wrinkled skin, thinly beset with horny scales. The shield is of an oval form, narrowest liehind. It is of a yellow colour, with black spots. The legs, especially the fore legs, are proponion- ably longer than in many other species ; and both C H E L O N I A. the fore and hind feet are furnished with two sharp claws. The individuals of this species are most abundant in the tropical seas, especially about the West India islands ; but they are also found in the Mediterranean particularly on the coasts of Sicily and Sardinia. In its manners, this is one of the fiercest of the chelonian tribe ; it defends itself with great courage and activity, both with its mouth arid claws, and has been known to snap a moderate-sized walking-stick with a single stroke of its jaws. It appears to be the most predacious of all the turtles, not only feeding on shell fish of considerable size, the habitations of which it easily breaks with its strong mandibles, but attack- ing the young crocodiles, seizing them by the tail as they retire backwards into the water. Thus these annuals instinctively perform an act of retributive justice. The older crocodiles make a prey of the eggs and young of those turtles which inhabit the shores to which they resort, and the turtles in return seize on the young crocodiles while they are too weak to defend themselves. The loggerhead turtle wanders very far from land. It has been seen apparently sleeping on the surface of the ocean, about midway between the Azores and Bahama islands, at a distance of many hundred miles from land. The female lays her eggs in the sand. The flesh of this species is coarse and rank, and eaten only by the lowest classes of the people. Its body, however, affords a considerable quantity of oil, which is used for burning in lamps, and dressing leather. The plates of its shell are too thin for most purposes, but have been employed in cabinet work. Chelonia coriacea, the leather-coat tortoise. There are several varieties of this specios, all inhabitants of the sea, and some of them found at least occasionally in the Mediterranean. Their shield, even on the back, is flexible and leathery, and they have no plates even on the under part. Their flesh is not eaten, neither is there any part of them used in the arts ; but it is necessary to attend to them with some care, as they have been confounded with some of the fresh- water tortoises. GENUS II. TORTOISES (Testudo). These admit of division into several genera or sub-genera, according to their appearance and habits ; and the species are very numerous, so much so, indeed, that we shall not attempt even to give a list of them. There are at least between fifty and eighty species, about thirty-six of which live generally in the fresh water, and the remainder generally upon land ; but both of them hybernate in the mud or earth. The fresh-water tortoises have all the toes sepa- rated, and generally a crooked claw upon each, though they are generally more or less webbed, or united by loose membranes. They have five toes on the fore feet, and four on the hind ; and the feet are adapted both for swimming and walking. Their principal food consists of insects, small aquatic animals and fishes, and some of them eat voraciously, though all are capable of long abstinence. Some of them have the shell more and some less consistent. European fresh-water Tortoise (Testudo Europeea). — This species is very common rn the south and east of Europe, and is found as far to the northward as Prussia. It grows to the length of about ten inches. Its shield is oval, not much convex, nearly smooth, of a blackish ground colour, and spotted over with yellow points disposed in rays. Its flesh is eatable, and it is some- times fed with bread and green leaves, but it also eats insects, common slugs, and small fishes. It is some- times made use of for clearing gardens of molluscous pests ; but it does not thrive unless the garden con- tains a pond of water, and if there are fish in the pond, it is very apt to lay them under contribution. Its general progressive motion is very slow, but its ; neck admits of rapid motion, and, indeed, the neck is the grand organ of motion in the whole order. The other fresh-water tortoises are chiefly met with in the warmer regions of the world, though they have more range in latitude than the sea turtle. Some of them have no scaly plates either on the j shield or the breast-plate, but are supported entirely I by the bones. They have in general their ribs pro- duced on the margins of their covering, so as to form i a border which is partially moveable, and of conside- rable assistance to them when they swim, which they ' do in shallow waters and among aquatic plants, where it is more difficult to make way than in the haunts of the sea turtle. They are also among the most active of the order ; and though they have not the strong protection of the horny shell, they are endowed with a degree of activity and courage, which much more than compensates. They are all inhabi- tants of the fresh waters ; and, with the exception of those in the sea, they are the largest animals of the order. We shall mention only the two principal ones. Soft Turtle of the Nile (Testudo triunguis). This species is found principally in that river from which it derives its common name. Its colour is green, spotted with white, and the shield on its back is a little convex. It is an active animal, preying on young crocodiles, of which it destroys great numbers It sometimes attains the length of three feet or upwards. Fierce Tortoise (Testudo ferox). This is the most formidable of all the tribe ; and as it has been con- founded by some writers with the coriaceous turtle, it is necessary to attend to the distinction between them. The coriaceous turtle has an oblong body, covered immediately with a bony shell ; but that shell is invested with a tough membranous coat resembling leather, plaited longitudinally, and the shield terminates behind in an acute point, over- hanging the tail. The body of the fierce tortoise is rounder and more convex, and the middle part of the shield is hard ; but its margin, especially towards the tail, is soft and pliable, resembling thin sole leather, and the hind part is rounded. The tail of the first species is long, and very thick at the root ; that of the second very short and small. The head of the former is small, round, and terminates in a beak, resembling the bill of a bird ; that of the "latter is proportionally larger and longer, with a long ta- pering cylindrical snout, having some resemblance to that of the mole. The coriaceous turtle is an inhabitant of the sea, is frequently found in the Mediterranean, and has been seen even on the coast of Britain. The fierce tortoise has yet been found otdy in the rivers and fresh-water lakes of America, especially in Florida and Carolina. The former is a large species, often measuring above seven feet in length ; the latter seldom weighs above seventy pounds. The fierce tortoise frequents lakes and muddy rivers, and hides itself among the water plants that C H E L O N I A. 17 grow at the bottom, from which it is said to spring suddenly on its prey. This consists of small water animals, and in some places, more particularly of young crocodiles, of which this species is extremely fond. They seize their prey by suddenly darting forward their long and strong neck, which they do with great celerity. This species is among the strongest and most active of its tribe, and as its trivial name implies, is possessed of ferocity and courage. When attacked, it boldly defends itself, rising on its hind legs, and leaping forward to seize on its assailant ; and if once it fixes with its jaws on any part, it is scarcely made to let go its hold without cutting off its head. Though the fierce tortoise does not form so exten- sive an article of commerce as the green turtle ; and perhaps on account of its activity, does not accumu- late the soft and luscious green fat which epicures prize so much, yet its flesh is wholesome and is eaten with avidity, especially by the Indians in those parts of America where it is most abundant. The Mud Tortoise (Testudo lutaria). The mud tortoise is the smallest of the fresh-water tortoises ; its whole length, .from the snout to the tip of the tail, seldom exceeding eight inches, while in breadth it is not more than three or four. It is of a blackish or dark brown colour. Its tail is nearly half the length of the shield, and is stretched out when the animal walks. Hence the mud tortoise has been sometimes called by the ancients mus aquatilis, or water rat. This is a very frequent inhabitant of lakes and muddy rivers in the south of Europe, and in many parts of Asia. It is very plentiful in France, espe- cially in the provinces of Languedoc and Provence. It lives almost entirely in the water, only going on land to lay its eggs, which it covers with mould. It moves with a quicker pace on land than many of this tribe ; when disturbed it utters a kind of inter- rupted hissing sound. It feeds on fish, snails, and worms, and often proves a troublesome inmate in fish ponds, killing many of the fish, and biting others till they are nearly exhausted from loss of blood. It has been proposed to employ the mud tortoise for destroying vermin in gardens ; but it is necessary to have a pond or large vessel of water for its ordi- nary residence. With such a convenience, it may be rendered tame and domestic. The young of this species, when first hatched, are not an inch in diameter. They continue to grow for a long time, and are known to live for many years. There are many other species of tortoise, which inhabit the fresh water, of which we shall only men- tion the Painted Tortoise ( Testudo picta), which is an American, and a very handsome species, at least in so far as colour is concerned. It is smooth, of a brown colour, and each of the scales is surrounded by a yellow band, which is broader at the anterior edge than any where else. It is found in North America chielly, and is more active than many of the others, often climbing rocks, and even trees, in search of insects, which constitute the principal part of its food ; but the moment that it is observed, it drops into the water, and so escapes. The land tortoises have in general the shell harder, and thicker in proportion to their size than any of the aquatic ones. In this way they follow a very general law of all animals, part of which inhabit the land, and another part the water ; for even the bones NAT. HIST.— VOL. II. of aquatic animals contain a much smaller portion of salts of lime than those of the most nearly allied species which dwell upon land. The land tortoises have the shield on the back supported by a frame-work of bones, which is united into one solid structure, so as to admit of little or no motion in the several parts ; and the sides of it are in great part firmly soldered to those of the breast-plate, the whole forming a complete sheath of immense strength. The legs arc very short, and so are the toes, which have five on the fore-feet and four on the hind. The nails or claws are strong and conical, and well adapted for digging ; but their motion is exceed- ingly slow. They can, however, move under the load of a much greater weight, in proportion to their size, than any other known animals. They are capa- ble of living for a long time without food ; and, in- deed, they are the very models of animal endurance. They are inoffensive in their mariners, and seldom or never attack any animal, except those insects, mol- lusca, and worms on which they feed, and many of them eat green vegetable matter. The greater num- ber of them, and perhaps the whole, spend part of the year in a state of hibernation, and bury themselves in the earth for this purpose. They do not construct a burrow with an entrance, as is done by the burrow- ing mammalia, but fairly sink down the body, throw- ing the earth on the back as they descend. This process is performed very slowly, but the progress of it is abundantly sure. In the course of their digging the head and tail are drawn within the shell, for all of them have the capacity of bringing both these and the feet within that covering. Their ascent to the surface is rather a more curious matter, and one which cannot be so well observed, but it may be pre- sumed to be performed by bringing the earth gra- dually under the feet, and forcing upwards the strong and convex shield, with that powerful action which enables them to bear so great a weight. Some of them have the power of enclosing all the moveable parts of the body entirely within the shell, by draw- ing firmly moveable pieces of the anterior and poste- rior parts of the breast-plate against the correspond- ing portions of the shield. Those which can do this are called box tortoises ; and they shut their box with as much firmness as the whole race are capable of shutting their jaws. There are a good many species, but we must restrict our notice to one or two. The Common Land Tortoise ( Testudo Grcsca). This species seldom attains a foot in length. It is of an oval form, with a very convex shield, broader behind than before. The breast-plate is nearly of equal size with the shield, and is of a pale yellow colour, with a broad dark stripe down each side, while the middle part of the shield is of a blackish brown mixed with yellow. The head is small, and covered on its upper part with irregular scales ; the mouth is small, the legs short, and the feet pretty broad, and covered with strong ovate scales. The tail is very short, scaly, and terminated at its extremity with a curved horny process. It seldom weighs above three pounds. This species is entirely confined to the land, and prefers elevated woody situations. It is found in Europe, Asia, and Africa, and is very common on all the coasts of the Mediterranean sea, especially in Sardinia, Barbary, and probably in Egypt. It is not a little curious that, even in the warmer climates, this species regularly retires to its subterranean quarters during the winter months ; thus proving, what we 18 C H E L O S T O M A. have before remarked, that the hibernation of these animals does not depend solely on the degree of cold. It begins to bury itself in October, and usually makes a hole about two feet below the surface, where it continues till April. The males of this species are in summer tolerably active, and very fierce towards each other. The fe- male lays her eggs towards the end of June, deposit- ing them in a hole, and covering them with sand or mould. They seldom exceed five in number at one time, and are of a white colour, and about the size of those of a pigeon. They are hatched towards the end of September, and the young, when first ex- truded, are scarcely bigger than walnut shells. The individuals "of this species live on roots, fruits, worms, and insects, the shells of which latter they easily break with their strong jaws. It" has sometimes been alleged that land tortoises do not drink ; but this is not correct : they are, no doubt, abstemious in their drinking, as well as in their eating, but it is well authenticated that they drink water, and that they are even partial to milk. They are very long-lived creatures ; and some of them, even when removed to a colder latitude than that of which thev are natives, have remained healthy for upwards of a century. Their flesh is eatable, and forms an article of human food in Greece ; and the Italians eat the eggs, though not the animals them- selves, at least not generally. Several varieties of this species are described by systematic writers ; but they differ little from each other, except in the mark- ings of the shell. The Indian tortoise is a large species, of which in- dividuals have lived, at least for some time, in Bri- tain. One species, presented to the Zoological So- ciety of London, in 1833, measured along the curve of the back four feet four and a half inches ; the length of its sternum two feet eight ; the breadth of the same two feet one ; its total weight two hundred and eighty-five pounds. This individual had lived seventy-seven years at Port Louis in the Island of Mauritius. A large specimen from Bengal, which had died at the gardens of the Society some time previously, enabled a more careful examination to be made of its anatomical structure; but the details of these are not exactly adapted for a popular work. The Geometrical Tortoise (Testudo geometrica). This is a very beautiful small species. The shell is black, and the plates, though of considerable thick- ness, are flattened into regular discs, which are beau- tifully marked with yellow rays proceeding regularly from centres. CHELOSTOMA (Latreille). A genus of hymen- opterous insects, belonging to the section comprising the bees, Mcllifera, family Apidcs, and sub-family Dasygastres, of Latreille, having the body very long, narrow, and nearly cylindric, with the mandibles advanced, narrowed, curved and notched at the tip ; the labial palpi are composed of a single joint, and the maxillary palpi are three-jointed ; the marginal cell of the upper wings is not narrow at its extremity, and the second abdominal segment of the males is furnished beneath with a curious horny tubercle, answer- ing to which is a singular cavity, covered with satiny down near the anus ; like the division to which it belongs, the belly is amply furnished with a coat of down in the females, which serves for carrying the pollen gathered by the insect, destined for the sup- port of her progeny. These insects, when asleep, roll themselves up somewhat like the wood-lice, the ventral horn fitting into the anal cavity above men- tioned ; they usually take their luxurious repose in the middle of a flower, whence the type of the genu§ has obtained the specific name of Apis Jlorisomnis. An interesting account of the habits of this insect is given in the Entomological Magazine by Mr. Double- day, of which the following condensed statement will not prove uninteresting to our readers. Although the male is a perfect sybarite, a mere voluptuary, the female is the very model of maternal industry, her whole life being spent in providing for her family. Here we may observe, that in this, as in numerous other wild bees, there are no neuters, upon which depend the whole labour of the community; indeed here no community exists, each bee is solitary, and each female has to undergo the task of forming and provisioning its own nest with a sufficient supply of food for its young when hatched, which does not take place until the life of the parent has ceased, so that the young are deprived of that constant attendance, which the hive bees bestow on their progeny. The female chelostoma carefully selects a spot in the posts of trellice, or other out-door wood-work, pre- ferring the sunny side of those parts which are quite dry and going a little to decay ; she there pierces a hole nearly horizontally, about an inch in depth, then changing the direction, she proceeds perpendicularly, her powerful jaws being the only tools wherewith she gnaws her passage through the wood, kicking the saw-dust out of the hole, passing it from one pair of feet to the next. This burrow is nearly a foot long, and in it, when completed, she commences the con- struction of about twenty cells, which are to be filled with pollen paste, and in each of which a single egg is to be placed. As however in the construction of these cells, and the deposition of an egg in each, the bee must work upwards, it is evident that the lowest egg will be deposited first, and will consequently first arrive at the perfect state ; and unless provision were made for this circumstance, the first-born bee would either be compelled to remain a prisoner, in its cell until its upper brethren had taken their departure, or it must make its way through the cells placed above it, which could not be done without detriment to the inhabitants. Now the bee, exhibiting as striking an instance of that principle which we call instinct, as is to be found in any animal whatever, pursues a plan, not indeed by the operation of any thinking foresight, and still less being the result of education, which amply provides against this emergency, by again changing the direction of her burrow, at the bottom of the perpendicular part, so as to emerge again out of the paling. She then closes the hole just above the lower bend by a partition of fine sand, firmly glued together by means of a viscid saliva, with which she is copiously furnished ; then laying at the foot of the enclosed part a sufficient quantity of pollen mixed with honey from the nectaries of flowers, for the support of one larva, in the midst of which she places a single egg, and closes the cell in the same manner as she found its bottom. In this manner she proceeds till she has reached the top of the perpen- dicular part. The two orifices of the burrow are then closed up, the lower one with a mixture similar to that employed in the division of the cells, offering of course but little resistance to the force of the bees when arrived at the perfect state. The upper one, however, being more exposed to danger From rain CHENOLOBIA — CHENOPODE^. 19 which might enter, and getting into the nest, destroy the young larva?, is first closed in the same manner as the bottom one, to which is added a layer of much larger grains of sand, glued together in a similar manner, each being tixed in the most convenient place by the assistance of the mandibles. Notwith- standing all her care, however, various parasitic insects contrive to deposit their own eggs in the cells in the absence of the parent bee, the progeny of which, of course destroys that of their fosterer, amongst which the Chrysis ci/nnea, the Ichneumon manifestator, and the Ftenus jaculator, have been observed by various authors. The insect whose proceedings we have here described, varies in length from one-third to half an inch. It is not uncommon, and is of a black colour, with ashy hairs; the female, which is the Apis maxillosa of Linnaeus, has the seg- ments of the abdomen margined with white. CHENOLOBIA (Leach). A genus united to that of Coronuln. CHENOPODE^E— Goosefoot family. A natural order of dicotyledonous plants, containing nearly thirty genera, and upwards of two hundred species. It is so closely allied to Amarantacece that, although the orders are quite different in general habit and appearance, still, it is not easy to get any constant distinguishing characters. Professor Lindley justly declares, that though he is unable to give any good artificial distinctions, he at the same time cannot hesitate to keep asunder orders which nature has obviously divided. This order, which was denomi- nated by Jussieu Atripliccs, has also an affinity to Phytolacece, from which it is separated by the stamens never exceeding the segments of the calyx, and being opposite to them. The essential characters of the order are : perianth monophyllous, deeply divided, sometimes tubular at the base, persistent, with an imbricated aestivation ; stamens inserted into the bottom of the perianth, and opposite to its segments, equal to them in number or fewer ; ovary single, free, rarely cohering to the tube of the perianth ; one ovule fixed to the bottom of the cavity of the ovary ; style two to four cleft, rarely simple ; stigmas undivided ; fruit membranous, some- times berried ; embryo curved round a mealy albumen, or spiral, or doubled together, without albumen ; radicle next the hilum. The plants belonging to the order are herbs or low shrubs, with alternate, sometimes opposite, leaves, with- out stipules, and small, occasionally polygamous flowers. They are generally distributed over the globe, more particularly in extra-tropical temperate regions, and are found abundantly in the northern parts of Europe and Asia. In general they are weeds which are not remark- able for their beauty, and are not esteemed as orna- mental plants ; several of them are avoided on account of the disagreeable odour which they emit. Nevertheless, many of the species are highly useful to man, some being cultivated as pot-herbs and articles of food, others being used medicinally on account of their tonic properties, and others again being valuable in a commercial point of view, on account of the alkaline substance which they furnish. They are propagated by cuttings, divisions and seeds. Some of the chief genera of the order are, Ckenopo- dium, Atriplex, Basella, Beta, Salsola, Salicomia, Blitum, Spinacea, and Camphorosma. The genus Chenopodium, goosefoot, whence the name of the order is derived, furnishes nearly sixty species, thirteen of which are natives of Britain. They are succulent weeds, the leaves of which are usually covered with powdery granules. Chenopodium Bonus Henricus, good King Henry, wild spinach, mercury goosefoot, grows abundantly in waste places and by way sides all over Britain. It is a hardy plant, of early growth, flowering in August, and is cultivated in some parts of England, more particularly in Lincolnshire, instead of spinach. The young shoots, after being peeled and boiled, are eaten as asparagus, and possess laxative qualities. The leaves are sometimes applied to wounds, and are used for cleansing old ulcers. Chenopodium album, white goosefoot, is perhaps the most common British species of the genus. The whole plant is covered with a white, mealy, unctuous substances which, by age, becomes dry and chaffy. In a young state, it is sometimes boiled in place of greens, and is known by the name of fat ken in some parts of Norfolk. Cheno- podium rubrum, red goosefoot, is another British species, which is found in waste ground, and often in low muddy situations. A considerable quantity of saline matter exists in the juice of this plant, which sometimes crystallizes on the surface of the stem. In exposed situations, the whole plant assumes a red colour. The plant is said to be poisonous to swine. Chenopodium maritimum, annual sea-side goosefoot, has been used as a pot-herb, and is burned in order to yield carbonate of soda. Chenopodium olidum, or valvaria, stinking goosefoot, is found in waste places, and under walls, especially near the sea in many parts of Britain. The whole plant exhales ammonia, or hartshorn, and when recent it has a nauseous taste and a strong offensive smell, resembling putrid salt fish. The odour remains long on the hands after the plant has been touched, in consequence of the greasy pulverulent substance found on the leaves adhering to them. The medical properties of this plant are to be attributed to its fetor. It was formerly used as a powerful antispasmodic, more especially in hysterical affections. It loses its properties by drying, and consequently must always be employed in a recent state. The presence of ammonia, a com- pound of hydrogen and nitrogen, in this and a few other individuals of the vegetable kingdom, is a circumstance well deserving of attention. Cheno- podium botrys, or Jerusalem oak, a native of the south of Europe, is filled with a resinous viscous juice, which stains the hands. The leaves when bruised emit a strong odour, and were formerly pre- scribed in the form of a decoction in some pectoral complaints, such as asthma and catarrh. This species, as well as Chenopodium ambrosioides, yield an essential oil, possessing stimulant, tonic, and antispasmodic qualities. The latter species, which is a native of Mexico, has sometimes been called the Mexican tea plant, in consequence of an infusion of it having been formerly used in place of the Chinese beverage. A decoction of the plant has been recommended in palsy. Chenopodium quinoa, a native of Chili, is very generally cultivated in Peru, its leaves being eaten as spinach or sorrel, and its seeds as rice. It is also used in the preparation of a kind of beer. Dombey, on his return from Peru, endeavoured to introduce the plant as a culinary vegetable into France, but his attempts were not followed with success. Chenopodium anthelminti- cum yields an essential oil, known in North America by the name of worm-seed oil, which possesses B2 C H E N O P O D E JE. powerful anthelmintic properties. Similar qualities are attributed to the seeds of this plant. Of the genus Atriplex, or Orache, there are upwards of forty species, seven of which are natives of Britain. Atriplex horlensis, garden orache or mountain spinach, is a native of Tartary, and has been used as a pot- herb. There are several varieties of the plant, more or less tinged with red and purple. The seeds are emetic, and also cause painful diarrhoea. Atriplex halimus grows on the sea coast in the south of Europe, and in this country, its silver coloured foliage adds to the beauty of our shrubberies. Spinacia olcracea furnishes the true garden spinach. There are numerous sorts of spinach, which vary in the shape and size of the leaves, arid the greater or less pinkiness of the seeds. The broadest and thickest-leaved varities are the most esteemed. The seeds are sown in spring and autumn, and grow readilv in any kind of soil. The prickly sort are the best tor winter crops, and the round for summer. Basella rubra and cordifolia are two species of Malabar night-shade which are found in the East Indies, Amboyna, and Japan. They bear spinous berries of a very dark red colour, which are used for staining calicoes in India. The leaves are eaten as spinach by the Chinese, and the plants are sometimes culti- vated as culinary vegetables in the neighbourhood of Paris. Seta vulgaris yields the culinary root, well known by the name of garden beet, which is so extensively used as a salad or pickle, and from which sugar is sometimes prepared on a large scale. There are several varieties of the plant in cultivation ; but the two chief are the red or purple, and the white with red bands. Those most esteemed for salad are the small red and castelnaudary, while the green-topped are the best adapted for yielding sugar. The larger and deeper coloured the roots are the better. The seeds of the beet are sown in March or April, in deep, well-comminuted soil, and when two or three proper leaves appear, they are thinned in such a way as to allow a square foot of surface for each. By the months of September or October the roots are fit for use, and they are then taken up and preserved in sand. Beet-root, when taken in large quantity, acts as a laxative, but sometimes it proves injurious to the stomach. The juice of the root and leaves causes sneezing. Sugar has been obtained in very large quantities from the beet-root. The plant was for- merly extensively cultivated in Germany and France for this purpose, and it is still reared in considerable quantities. During the late wars, when the sugar from the British colonies was not allowed to be exported to France, the beet-root was the only source from which sugar could be procured, and consequently its cultivation became an object of national interest and importance. The usual way in which the sugar is obtained is as follows : — The roots, after being washed and cleaned, are sliced and grated down, and afterwards bruised in successive portions of water, until all the saccharine matter is dissolved. The iluid is then filtered and evaporated, and ultimately purified and crystallised. Besides sugar, the roots contain water, fibrous matter, mucilage, starch, and colouring matter. In general they yield from two to five per cent, of sugar. M. Achard computed that a German square mile, which is equal to sixteen English square miles, would produce boet sufficient to furnish sugar to the whole Prussian dominions. Sugar, however, cannot be advantageously obtained from this source, inasmuch, as the expense" attending its preparation is too great when compared with the quantity produced. A considerable quantity of beet sugar is, nevertheless, annually prepared in France. Beet-roots, when deprived of their juice by pressure and afterwards dried, may be used in place of malt in brewing. The beer made from them is said to be pleasant and wholesome. The leaves of the beet, when reared in a rich, well manured soil, yield a considerable quantity of nitre or saltpetre. Beta cicla, a name corrupted from Sicula, meaning Sicilian beet, produces a root, not by any means so large as that of the common beet. The leaves serve as a substitute for spinach, and the young shoots and mid rib of the leaves are eaten like asparagus. The plant grows in great quantity in the south of Germany and in Switzerland. A large variety has been intro- duced from abroad, under the name of mangel wurzcL This variety, on account of the large size of the roots, is now extensively cultivated in this country. It is much used for feeding cattle during the winter. In cultivating this variety, more room is required than in the case of the common beet, on account of the size of the root and leaves. The roots are some- times applied externally as a poultice to ulcers. The only British species is Beta maritima, a sea beet which, when boiled, is esteemed a wholesome article of food. Most of the species of Salicornia, another genus of this order, abound on the shores of the Mediterranean, and two of them are natives of Britain. Salicornia herbacea, the most common British species, is gathered when in flower, and pickled in salt and vinegar like samphire. The whole plant has a saltish taste, and is eagerly eaten by cattle. Salsola kali, or prickly salt-wort, is common on the sandy sea coasts of Britain, and has also been used as a pickle. Salsola fruiicosa, found on the shores of the southern counties of England, deserves a place in gardens as being a hardy evergreen. The Salicornias, Saholas, various species of Atriplex and Anabasis, as well as the Cheiw- podiums found in salt marshes, as well as several other plants belonging to the same natural family, growing in the south of Europe and north of Africa, yield, when burnt, a vast quantity of the substance called barilla, an impure carbonate of soda, which is used in making glass and soap. The English name of g/asswort, applied to Salicornia, is derived from this circumstance. Salsola soda is cultivated extensively in Languedoc and Spain, for the preparation of barilla, which is usually exported to Italy and Sicily, but it is looked .upon as inferior to the Salsola sativa which grows on the Spanish shores of the Mediter- ranean. The latter species supplies the Alicant or Spanish barilla, which is the best that is consumed in Europe. The production of soda depends solely on the proximity of the plants to the sea, for it is from this great saline reservoir that the alkaline matter is derived. The same plants, when cultivated in the interior and far from the shore, yield totally different products. The maritime plants employed in the preparation of soda, differ in different countries, and the quantity of alkali obtained is very various. Thus, while some kinds of barilla yield from twenty-five to thirty per cent, of alkali, others only yield twelve or fifteen ; and the coarser substance called kelp, obtained C H E N O P O D I U M — C H E R R Y. 21 from sea weeds, yields only two or three per cent. The preparation of barilla is carried on to a great extent on the shores of the Mediterranean, and there the seeds of various maritime Chenopodece, are regu- larly sown in places near the sea. In the month of September, when the plants have attained sufficient maturity, they are pulled up by the roots and exposed to dry, so that the seeds may be collected ; they are then gathered into heaps, and afterwards burned in holes made in the ground, or in ovens constructed for the purpose ; the ashes are constantly stirred, while hot, with long poles, and a hard mass ultimately remains, which, when broken into pieces, constitutes the barilla of commerce. The best sort of Spanish barilla has a dark bluish colour, is verv heavy and dry, has no offensive smell, and is covered externallv with numerous small depressions. That which is mixed with small stones, and gives out a disagreeable smell in solution, and is deliquescent, ought to be rejected as bad. From barilla, carbonate of soda is easily obtained by lixiviation in boiling water, and subsequent evaporation. Carbonate of soda is of great use in the arts and manufactures, more especially in the formation of glass, and in the preparation of various kinds of soap. Glass is formed by mixing soda or potass with sand in certain proportions, and exposing the mixture to a strong heat, until the materials are fused ; It is then moulded into different forms under the name of flint, crown, plate, and bottle glass. Bottle glass is the coarsest kind, and is made from river sand, which contains iron and other impurities, and the common impure alkali. Crown glass, for windows, requires fine sand, free from iron, and a pure alkali; white plate glass, for mirrors, is made from the purest materials. To the glass commonly called flint glass, some oxide of lead and manganese is added. Soap is prepared by mixing different kinds of oil, in a greater or less degree of purity, with carbonate of potass or soda; the former alkali being employed in the preparation of soft, and the latter in the formation of hard soap. The soap ordered in medicine for internal use, is formed from the finest olive oil and pure carbonate of soda. . The purest barilla, though well fitted for ordinary manufactures, does not serve for chemical purposes, on account of the mixture of the sulphates and muriates of potass and soda. A carbonate of soda, considerably purer, is easily got by exposing sulphate of soda, or Glauber's salt, with saw-dust and lime, to the action of a reverberatory furnace, and after- ward-: lixiviating and crystallising. lilitnm is another genus of this order, furnishing several species, one of which Blitum capitatum, berry- headed strawberry blite, is a native of Austria. In this species, after the flowers are faded, the heads swell to the size of wood-strawberries, and when ripe, have the same colour and appearance. They are succulent and stain the hands, and were formerly used by cooks for colouring puddings. Another 'genus •jihorosma, receives its name from emitting a smell of camphor. From the above account of the Chenopodcr which this tree is so suitable for underwood. Here the greater number of stems which rise at once from the root, not only increase the value of the pro- duce, but improve the form of the poles, by inducing a more upright and straight growth. From the circumstance of many of the principal timbers in the roofs of our cathedrals being found to be chestnut, it has been surmised by several writers, that this tree was once plentiful and of great size in this country. The only argument against the probability of this idea is, the present scarcity of this tree in our parks and natural forests ; for, if they were at any former period natives, why should this kind of tree have so suddenly disappeared. The greater probability is, that when a cathedral was about to be built, all Christendom was called on to assist, especially when the Pope could issue imperative commands on such occasions. And it is most likely, that the beams and rafters of Westminster and other cathedrals, were from the forests of Spain and Italy. As a fruit tree, the chestnut is of little value in England, it being only in very favourable seasons that the nuts come to perfection. As an ornamental and timber tree, however, it deserves the first notice of the planter ; and as it has been pretty extensively planted within these last four-score years, another generation, perhaps, may see chestnut timber as plentiful as the best oak is at the present time. Sweet chestnut underwood, judiciously planted on light loamy soil, and carefully managed, proves a profitable possession ; the produce being usually fit to cut every eight or ten years, and sells at high prices. Hop growers prefer chestnut poles, as well for their regular form as durability ; and the stools yield great numbers of stakes and headers for fencing. CHICK PEA is the Cicer arietinum of Tournefort. This plant is cultivated in the south of Europe, where it is indigenous, and is an article of diet among the poor, but is chiefly used for feeding poultry. CHIGOE, or, as the English residents in the West Indies have corrupted the name, Jigger. A species of insect belonging to the family of fleas, PulicidcE, but considered by Latreille as probably forming a distinct genus. The names Nigua, Tungua, and Pique, have also been applied to this insect, but Latreille has considered that the first and third belong to the Acarus Americanus, whilst he gives the Chigoe as another species of Acarus. Mr. Mac Leay, however, who, from his residence at the Havannah, must be con- sidered a more competent authority, states that the Spanish name for the troublesome Pulex penetrans is .A%w6r,and the British West India name Chigoe or Jigger. The habits of this insect are very different from those of the common flea. According to Stedman it gets in between the skin and the flesh without being felt, generally under the nails of the toes, where, while it feeds, it keeps growing till it (or rather its habitation) becomes of the size of a pea, causing no further pain than a disagreeable itching. It will, however, attack any exposed part of the body ; indeed an instance has been recorded where it got into the hand. In process of time its operation appears in the form of a small bladder, in which are deposited thousands of eggs or nits, and which, if it breaks, produce so many young chigoes, which in the course of time create running ulcers, often of very dangerous consequence to the patient, so that at times the soles of the feet are even obliged to be cut away before the patient can recover, and some men have lost their limbs by amputation, nay, even their lives, by having neglected to eradicate these abominable vermin. The moment, therefore, that a redness and itching more than usual are perceived, it is time to extract the chigoe which produces them. This is done with a sharp pointed 24 CHILOCHLOA— CHILOGNATHA. needle, taking care not to occasion unnecessary pain and to prevent the chigoe from breaking in the wound The female slaves are often employed to extract these pests, which they do with uncommon dexterity, Tobacco ashes are put into the orifice, by which in a short time the wound is healed. Here, however, as in the attacks of most other tormenting insects, we find that cleanliness is the best preservative, person who take care to wash their feet often, being but little subject to annoyance. It is likewise found that rub- bing the feet over with bruised tobacco leaves is a preventive against them. Great uncertainty pre- vailed as to the real nature of this insect until Swartz investigated its history, and published a short paper upon it in the Stockholm Transactions, proving that it belongs to the flea family. He has, however represented it with a long porrected proboscis. CHILOCHLOA (Beauvois). This is a genus o: grasses, formerly known and included under the genus Phleum. They are mostly annuals, and of no value as agricultural plants. CHILOGLOTTIS (R. Brown). A curious tuberous rooted orchideous plant from New Holland introduced into our collections about 1823. This is a pretty hardy plant, and is usually kept in a frame, planted in turfy moor-earth, or " in the open border if care be taken to defend it from frost." — Sweet. CHILOGNATHA (Latreille, MacLeay). An order of wingless insects, corresponding with the apterous genus lulus of Linnaeus, and distinguished by having the body long, crustaceous, and often cylindric, and the antennae seven jointed, and forming, in the system of Latreille, one of the two families of which the order Myriapoda is composed, the other being formed of the Centipedes, Chilopoda, or the Linnaean genus Scolojjcndra. These two groups have many characters in common ; they are equally pos- sessed of a very great number of legs ; the abdominal are not distinguished from the thoracic segments, as they are in true insects. The body, destitute of wings, is composed of an extensive series of segments, of equal size, and bearing, with the exception of the anterior, two pairs of legs, as noticed in our article on the Centipedes. The Myriapoda somewhat resem- ble small serpents or nereides, having the legs fixed close together throughout the whole length of the body. The antennae are two in number; the eyes are composed of an union of ocelli, and if, in some species, these organs offer a faceted cornea, each of the lenses is much larger and more distinct than in the true reticulated eyes of insects ; the number of the legs, as well as of the segments of the body, increases with the age of the animal. These animals live, and continue to increase in size for a much greater period of time than insects; and, according to M. Savi, two years are required before the organs of generation become at all apparent. Hence we may conclude, that they approach, in some respects, to the Crustacea and Arac/mida, and in others to the true insects ; but, from the consideration of the presence, the form and the direction of the tracheae, they must be considered rather as belonging to the latter. Mr. MacLeay has united them with the Anoplura (lice), Tkysanoura ^sugar lice, &c.), and some apterous vermes into a class, to which he has applied the term Ametabola. In addition to the characters first above mentioned as distinguishing the Chilognatha, it may be mentioned that the legs are very short, terminated by a single claw ; two short antennae ; the mandibles are crus- taceous, without palpi, and three jointed ; but the more distinguishing character of the Chilognatha is the position of the sexual organs near the anterior part, and not the extremity of the body ; those of the male being placed behind the seventh pair of legs, and those of the female behind those of the second pair. These animals walk but slowly, and with an undulat- ing motion, produced by the progressive action of the numerous legs ; the majority of them, when disturbed, roll themselves up into a ball. They feed upon animal and vegetable substances in a state of decay, and lay a very considerable number of eggs in the earth. From these eggs the young are produced, at first without any appendages to the body; eighteen days afterwards, however (in the genus lulus, accord- ing to M. Suvi of Bologna, who has made these insects the subjects of two valuable memoirs), the skin is cast, when they appear with twenty-two seg- ments, and twenty-six pairs of legs, of which, the first eighteen serve for locomotion ; at the second moulting the animal has acquired thirty-six legs, and at the third forty-three ; the body being then composed of thirty segments ; and in the adult state, the male has thirty- nine, and the female sixty- four. A very small species of this group attacks the strawberry, another the endive, others are found in moist places, under the bark of trees, &c. There are numerous species belonging to this order, some of those from South America acquiring a large size — the lulus maximus being seven inches long. Of the British species, Dr. Leach has given a very good Monograph in the Zoological Miscellany. This order is divided by Latreille, in his last work, into three families : — 1st. The Omsciformet, having the body of a crustaceous texture and of an oval-oblong form, without pencil-shaped appendages, and capable of being contracted into a ball ; the under side of the body being concave. The number of legs is thirty- two in the males, and thirty-four in the females. This family comprises but a single genus, Glomcris, Latreille, the species of which are found under stones, especially in mountainous and woody districts. This group is highly interesting to the naturalist, from the remarkable anology which it presents to certain crustaceous animals, to which the name of wood lice has been given. Indeed, so strong is the relationship, not only in form, size, and general appearance, but also in habits, that it is no wonder that, by the majority of British naturalists, who have, in general, cared too little for more than the outward appearance of things, the Glomeris marginatus, belonging to the ametabolous order Chilognatha, should have been regarded as a mere variety of the Armadillo vulgaris, aelonging to the crustaceous order Isopoda. We :rust that better times are dawning on natural history, as a science, in its legitimate sense, in this country. For the purpose of comparison we have represented the two animals above mentioned, from which it will be seen how close is the proximity between the two groups. 2nd. The Anguiformes of Latreille, having the body of a crustaceous texture, but of a long and narrow brm, and unprovided with pencil-shaped appendages. Here belong the genera lulus and Craspedosoma, laving the eyes distinct, and Poludesmus in which hey are obsolete. 3rd, The Pcnicillata of Latreille, having the body soft, oblong, and furnished behind with small pencil- C H I L O P O D A— CHINCHILLID^;. like brushes. The legs are twenty-four in number. The genus Polyxemts, Latreille, belongs to this family. The type is found in profusion beneath the bark of trees. 1, Glomeris marginatus. 2, Armadillo viilgaris. . CHILOPODA (Latreille; Syngnatlia, Leach). An order of wingless insects, corresponding with the Linnasan genus Scolojiendra, and distinguished by having the body of a leathery-tike texture, and depressed, and the antennae composed of fourteen or more joints. See CENTIPEDES and CUILOGNATHA. Having, in the former of these articles, given an account of the structure and habits of the animals of which this order is composed, it only remains for us, in this place, to give a short sketch of their classifica- tion. Dr. Leach, in the Supplement to the Encyclopaedia Brittanica, has divided this order into three families. 1st, The Ccrmntada: (Inccqnipedes of Latreille's Cours d' Eutouiologie), having the body proportion- ably short, with the upper surface protected by eight plates, and with the under divided into fifteen semi- segments, each bearing a pair of legs, terminated by a very long and multi-articulate tarsus. This family, which is composed of the single genus Cermatia, is formed of exotic insects, frequently found in houses under beams or joists of the wood work, running with great velocity, and often losing many of its legs when seized. '2nd, The Scolopendridts^JEquipedes, Latreille), hav- ing the body, divided both in its upper and under surface, into an equal number of segments ; the legs short and of nearly equal size, the posterior pairs being but little longer than the anterior. Here belong the true Centipedes, Sco/o/xndra, and the genera Cryplops and Lithobius, of each of which there are British species. 3rd, The Geojrfiilidce (united with the latter by Latreille), and having a very great number of equal sized legs, the body being narrow and almost filiform, each segment bearing two pairs of legs. Some species are luminous, as the Gcophi/ut elect ricus. Figures ol Geophilus longkvrnis, and of Lit/uAiiis forcipatus, two British species, serving as types of those two families, will be found in our article CENTIPEDES. CHIMONANTHUS (Lindley). A fine orna- mental flowering shrub, a native of China and Japan ; Linn&an class and order Icosandria Polygynia ; natural order Rosacea:. Generic character : perianth scaled; outer lobes like bractas, inner lobes resem- bling petals; corolla, none; stamens inserted in the fleshy throat of the perianthe ; exterior ones perfect and small ; anthers adnate and two-celled, interior like threads and downy ; styles several and filiform. This plant, on its first introduction into Europe, was called Calycanthus prcecojc ; afterwards described as Mcralia, by Loiseleur Deslongchamps, in his Flora Gallica ; but finally named by Lindley in the Botani- cal Register. 25 This plant is greatly esteemed by the Chinese, not only for its early flowering and fragrance, but for some medical extract obtained from it, and which is parti- cularly available in counteracting the virulence of the small-pox, so much dreaded by that smooth-faced people. It is almost hardy enough to bear the open air in this country ; but as it flowers in winter, and as Frost tarnishes the blossoms, the best way to see it in beauty, is to give it a place in the conservatory, or against a south wall in the flower garden. Mr. Sweet states that there are three varieties or species in the London collections, all of which thrive in any kind of garden soil. The plants are usually raised from layers, or by young cuttings planted in sand under a lass, and placed in hotbed heat. Seeds sometimes ripen in this country, whence seedlings are easily raised. CH1NCHILLIDJE. The chinchilla family, an exceedingly interesting, and, in so far as individuals are concerned, a remarkably numerous group of rodentia, or gnawing animals, inhabiting the southern parts chiefly of South America. The fur of one species (lanigera), has been known and highly prized for a considerable number of years ; but it is not very long since much was known in Europe, either of the animals themselves, or even of the country of which they -.vere natives. It has now, however, been tolerably well ascertained that there are three distinct species, if, indeed, they ought not rather to be, as they sometimes have been considered as separate genera. They all belong to the herbivorous division of gnaw- ing animals, and their teeth are adapted for bruising the hard and dry vegetation upon which, from the peculiarity of their native regions, they are sometimes obliged to subsist, as well as on the more succulent leaves which they can procure in the season of growth. They are all gentle and inoffensive animals, spending great part of their time in their burrows under ground, though in many parts of the plains their burrows are so very numerous, that the horses of travellers and hunters are in constant danger of stepping into them, and throwing their riders, and fracturing their legs. At one time they were confounded with the hamsters (cricetia"), to which they have a good many points of resemblance ; but still, in their appearance their structure, and their locality, they are fully entitled to rank as a distinct family, and a family which gave no small portion of its original character to the zoology of the district in which they are found, Nor is it a little remarkable, that two portions of the world, which, from the geographical antipodes to each other, at least, as nearly as any two portions of land of considerable extent should have a remarkable coincidence in their mammalia, even although in climate, as well as in local position, they differ very much. Siberia, especially the southern parts of the steppes, which lie near the bases of the Altaian moun- tains, have, in many respects, a structural resemblance to the pampas or plains which lie between the Rio- de-la-Plata, and the southern Andes. Both arc flat, and composed in great part of sand. Both are, in many places, burnt up at one season of the year, and covered with rich herbage at another, and both are but thinly inhabited, in consequence of the paucity of their productions as serviceable to man ; but both contain an immense number of herbivorous rodentia. In respect of its fur animals, Siberia is, indeed, a sort 26 CHINCHILLID^E. of union of the two ends of the American continent ; the woods furnishing animals not very dissimilar to those which are found, in such vast numbers, to the north westward of Canada, while the open and arid- places present us with those of Paraguay, or rather with animals resembling these in their general habits. But still there is a great difference in the climates of the two places ; for, though the southern Andes, on the parallel alluded to, are subjected to more violent storms than any part of Siberia, the plains have a much greater uniformity of temperature, so much so, that up to the very southern extremity of the American continent, vegetation retains a tropical character. We might, therefore, be prepared to expect a considerable difference between the appearance aud covering of the animals which perform the same part in the economy of nature in each of the two. And, accord- ingly, we find the fur upon the American animals much more delicate, and not nearly so well adapted for throwing off snow as that of the Siberians. They are also more gentle animals ; and they probably more habitually burrow in the ground. The characters of the chinchillidae are,— two simple incisive teeth in each jaw, and four grinders in each side of both jaws. The grinders, as is general in all the herbivorous part of the order, have no roots, and are not produced in the substance of the gum, but grow, adhering to its surface ; and, as is the case with all teeth that grow in this manner, they continue grow- ing during the whole life of the animal. Animals of this tribe have all to subsist on very hard food at some eason or other ; and therefore, this constant growth >f the teeth is a very wise provision for them. The eeth of the family under consideration have parallel •lates of enamel and osseous matter ; and their bruis- ug crowns act directly against each other. There are three genera, Lagostomus, on the east art they reside, and in which they change to pupae. An anecdote is recorded respecting these blood- C H I R O T E S. worms, which is quite sufficient to prove that, in this case at least, even a little knowledge of natural history would not have been a dangerous thing. A medical gentleman having observed these larvae very numer- ous in the water of a well, in the neighbourhood of Cork, considered them to be the true origin of the common small thread-worm (Qxyuanu vermtcvlofii) occasionally found in the human intestines, the former differing only from the latter in colour. Had he, however, but placed some of these worms in water of a temperature equal to the human body, he would soon have discovered that they were not long able to bear the increased heat of their native element. Reaumur found the larva? of one of the species in small brown paper-like cases, attached to various leaves which had fallen into the water in the Bois de Boulogne ; the cases were of a flattish spindle-shape, somewhat resembling an oblong seed, they were chiefly composed of silk, but Reaumur could not ascertain whether fragments of leaves might not also be employed in their composition. We are unable to decide as to the precise species observed by this author, but from his description it seems nearly akin to the C. plumosus. The fore legs are much longer than the others, and generally carried in an elevated position by this insect, so that they might easily be mistaken for antennaj ; moreover, they are generally kept in continual motion, now elevated, now depressed, whence the origin of the generic name, signifying a kind of gesticulation with the hands. The pupa has the head and thorax united into an oval mass, with the abdomen long and cylindric ; from each side of the thorax arises an elegant apparatus composed of five long finely feathered rays disposed in the form of a star ; the tail is also ornamented at its extremity with a fine brush of hair. The fore legs, from their general length, are inclosed in cases which, instead of folding upon the breast in the same way as the shorter hind legs, project from each side of the thorax in a very peculiar manner. Messrs. Kirby and Spence have given a very interesting account of the manner in which the insect, upon arriving at its perfect state, in which it is destined to pass its life in the air, effects its escape from the puparium, or skin of the pupa, the natural clement of which is the water. For the extrication of the imago it is necessary that it should remain quietly suspended at the surface, and more- over that the thorax in which the opening for its exit is to be made should be at least level with it, and this is precisely what takes place. By a most singu- lar and beautiful contrivance, not only is the pupa which is specifically heavier than water enabled to suspend itself without motion at the surface, but its thorax which is the heaviest end is kept uppermost. This is effected by the property which the centre of the thorax has of repelling water, hence as soon as the pupa has once forced this part of the body above the surface, the water is seen to retreat from it on all sides, leaving an oval space in the disk which is quite dry, hence the attraction of the air to the dry part ol the thorax is sufficient to overbalance the specific gravity of the pupa. If, however, when the pupa is suspended at the surface, a drop of water be let fall upon the dry portion of the thorax, it instantly sink to the bottom, the thorax which belongs to the heaviest half being the lowest, but if the pupa be again brought to the surface so that the fluid is repelled from its disk, it remains suspended there without effort as before. Just previous to the exclusion of the fly, th< dry part of the thorax is seen to split in the middle. The air enters and forms a brilliant stratum resetn- jling quicksilver between the body of the insect and its puparium, and the former, pushing forth its head and fore legs, like the gnat, rests the latter upon the water, and in a few seconds extricates itself wholly Larva, pupa, and perfect Chironomus. from the puparium. A more recent author has en- deavoured to throw some doubt upon the mode of solution of the manner in which the suspension is effected, asking in reference to that part of Messrs. Kirby and Spence's statement, which he quotes entire, which relates to the sinking of the insect when a drop of water is let fall upon it. " If so, we may ask what becomes of the power of the thorax to repel water?" We answer that, although the thorax may possess the power to repel the water immediately surrounding it in a quiet and undisturbed state, it does not follow, and indeed it would be absurd to suppose that it pos- sessed a power of repulsion sufficiently strong to resist the increased force of a drop of water let fall upon the heaviest portion of its body, especially at a period when the feeble creature is just as it vvere upon the point of bursting into life ; indeed in support of this opinion, we again find the same author adopting another idea of Messrs. Kirby and Spence, namely, that these midges fly unwetted in a heavy shower of rain, owing to their quickness of vision, since if the drops, bigger than their own bodies, fell upon them, they must be dashed to the ground, although he im- mediately takes up the idea of repulsion which he had before thrown down, and " unless it may be that the drops glide off their wings as they do off the fea- thers of a duck." — Insect Transformations, 319, 367. There are nearly a hundred British species of this genus, some of which are remarkable for the elegance of their colouring. Many of them form beautiful subjects for the microscope. CHI ROTES. A genus of saurian reptiles, which may be considered as intermediate between the lizards properly so called and those serpents which have rudimcntal bones of the extremities. From the cir- cumstance of having only two feet, this genus, or we may say, this species, for there is but. one, has been rather absurdly called lihitana ; but as that is the proper distinctive name of the human race in natural history, and as no animal but man is possessed of what can properly be called a hand, the extremities of apes and monkeys being merely grasping feet, it is of course improper to apply the term bimana to any species but the human race. This animal is the Lacerta lumbricoidcs of Shaw, but it cannot, strictly speaking, be considered as a lizard, and it has uo resemblance whatever to an earth-worm (lumbricits) in any one respect, except colour. It is one of those singular animals of which two or three are met with i'.i Mexico, and which have always puzzled the syste- 30 CHISMOBRANCHIAT A— CHITON. matists where to place them. The characters are : the head round, blunt at the muzzle, distinguished from the body by a simple fold, and covered with polygonal scales, which are large for the size of the animal but few in number ; the nostrils and eyes are not very conspicuous ; the jaws are of nearly equal length ; the body is long, cylindrical, covered with rather large four-sided scales, which are similar both on the back and the belly, and are verticillate or placed in whirls round the body ; there are only two feet which are very near the head, well developed, and each containing five toes with distinct claws ; and the tail is blunt. There is only one species, C. Mexicanut, which is about eight or ten inches long, and as thick as the little finger. It is marked with about two hundred and twenty rings of scales, which form a half ring on the upper part of the body, and another on the under, meeting each other at two lateral lines, which are very straight and very definite. There are two lines of pores on the under part of the body ; the tongue is a little extensible, and terminates in two small horny points ; its ears are covered with the skin, and consequently not visible externally. It is of a flesh colour, and in this, in its general appearance, and its being possessed of only one large lung, it approaches in character to amphisbo3na among the serpents, but in its skeleton it is very different. The bones of its two feet are well developed, having distinct blade- bones, and being supported by clavicles butting against a small sternum. Thus it can use its two feet with great dexterity in walking, in climbing, and in grasping. Altogether this is one of the most sin- gular animals with which we are acquainted, and the different parts of its organisation would lead to the placing of it in very different parts of the system. The bones are understood, though this point has not been very well ascertained, to resemble, m their gene- ral texture, the bones of warm-blooded animals more than those of reptiles, while the general external cha- racters bear at least some resemblance to those of the lizards, and respiratory system to that of the serpents. This animal is understood to be entirely insectivorous, and it is perfectly innocuous. CHISMOBRANCHIATA (Blainville). Second order of the second class of molluscs, Paracephalo- phora. The animals of this order possess aquatic organs of respiration, branchial or pectinated, placed at the anterior part of the back, in a large cavity, communicating with the ambient fluid by a large oblique, anterior slit. Mouth without teeth, but the lower part furnished with a lingual muscle ; some are without shells, some are interior or external, very flat, aperture very large, entire, and without a colu- mella. This order includes the genera Coriocella, Sigaretus, Cryptostoma, Oxinoe, Soumatella, and Vc- lutina. The order is composed of shells, all of which are marine, and the animal probably herbivorous. CHITON (Linnaeus, Cuvier, &c.) This singular mollusc has undergone no change by the arrangement of modern naturalists; its characters are so well defined, and possess so few variations, that it cannot by any possible chance become blended with other genera. It is a genus perfectly distinct from all other of the animal series ; they seem to form the transition from molluscs to insects. The separation of this genus into small natural groups is attended with much difficulty ; it may, however, be ultimately accomplished by careful study of the animal and its covering. The only certain guide hitherto pursued, are the sides of the valves, and the number of tooth- like processes each presents, when detached from the membranous substance which surrounds them ; the striae, granulations, punctures, and other external markings, also assist in classing the species. Lamarck observes respecting this well known but singular mollusc, that it seems more like an univalve than a multivalve, and should only be considered an elon- . gated shell, with the testaceous portions of it trans- versely broken by nature, at its first formation, into a number of distinct moveable parts, in order to faci- litate the animal's motion. These valves or testaceous portions may be considered never to vary in charac- teristic marks, beyond eight in number, though instances have been met with of specimens with only seven. These are inserted at the lateral extremities by certain toothed processes above alluded to, into a tough ligament surrounding the outer margin, firmly uniting them together in their proper position ; this ligament is sometimes fleshy, coriaceous, smooth, wrinkled, covered with scales, or beset with tufts of hair ; and in one species Chiton spinosus, it has nume- rous tubular, slightly curved, long thin black spines ; a tough internal membrane connects the under part of the valves or portions, allowing the animal to con- tract its shell in a globular form or fully to expand it. When these valves are all united on the animal's back, they form an elliptical shell, the centre part of which is more elevated than the rest; the valves slightly overlap each other, and each succeeding one is less convex towards the margin. One species has callous adhesions longitudinally placed on the back of the valves; some are elegantly marked by the arrangement of their striae, granulations, &c. The interior of the valves is generally white, but some are green, and one species a bright rose-colour; they adhere to rocks covered by the sea, to the backs of tortoises, fishes, or other marine objects, and so fast do they retain their position by exhausting the air beneath their bodies, that it requires a strong lever to detach them, frequently breaking tne shell before the animal can be forced from its position. The name chiton, is derived from the Greek, and means a coat of mail. The animal in its structure is not less sin- gular than the shell; its body is more or less lengthened, depressed, or sub-cylindrical, obtuse equally at both ends ; the abdomen provided with a muscular disc or foot, adapted to climbing, but most particularly to adhesion ; the back is sub-articulated, and corresponds with the different valves ; the mouth is anterior, and beneath, in the middle of a conside- rable mass; it has neither eyes, tentacula, or jaws, but it has a sort of straight tongue in the buccal cavity, bristled with denticules. The organs of respiration are branchial, and formed by a succession of small branchiae beneath the turned edge of the mantle, particularly at its back part. De Blainville places the chiton in the second class Polyplajciphora, of his sub-type of Malentozoaria, and he subdivides the genus into the following well-defined species: — 1st, Such as are depressed with large valves, carinated, much imbricated, the intermediate ones present- ing well marked lateral areas, the limb of the mantle regularly scaly, without hairy or silky tufts, as in the C, squamosus here figured. 2ndly, The sub-depressed species, with valves not carinated, much imbricated, and without marked areas, the lateral portions of the mantle covered with a species CHITON E LL U S — CHLENACE^. of hair or calcareous tubercles, as in the C. marmo- ratus. 3rdly, The species, whose form are similar to the preceding, the valves generally smaller, all the terminal ones much imbricated, without marked areas ; the lateral portion of the mantle either quite naked, or as if coriaceous, as in the C. piccus. 4thly, The species more or less cylindrical, vermiform, nearly naked ; the foot very narrow, as if articulated ; the branchia in the posterior half of the body only ; the valves very small, often separated or not imbri- cated, and always visible, as in the C. lacvis, consti- tuting Lamarck's Oscabrclla. 5thly, The species with the valves narrower, imbricated, without distinct areas, the lateral parts of the skin naked or hairy, but always furnished with tufts of silk or hair, arranged in pairs, as in the C.fascicularis ; and lastly, Such spe- cies as are more or less cylindrical, vermiform, nearly naked, the valves of the shell very small, almost entirely concealed beneath the skin, with tufts similar to the preceding section, as in the C. larveeformis, which constitutes Lamarck's genus Chitoncllus. These shells sometimes attain a large size, measuring four inches in length ; but they usually do not exceed two inches. They are found in every sea, the larger ones in warm latitudes ; but the shells of the last division have only as yet been found in Australia. One of a small size is found on the British coast. Fossil species are rare, but detached valves are sometimes met with in the calcareous sand formation, in the neighbourhood of Paris. CH1TONELLUS (Lamarck). A species of mollusc, forming one of the divisions of the genus Chiton, of De Blainville's system (which see). It inhabits the coast of New Holland, and from its external valves never being interlocked, it has the power of moving laterally as well as forward. CHITONIA (D. Don). Handsome shrubs and trees, natives of South America and the West Indies. Linnoean class and order, Decandria Monogyma ; natural order, MelastomacecE. Generic character : calyx of four parts, deciduous ; petals orbicular ; stigma pellate and hemispheric ; seed vessel four- celled, four-valved ; seeds two in each cell ; arillo fleshy and banded. The plants of this genus were formerly included in the genus Mclastoma, but have been separated by Mr. D. Don. CHIVES. A diminutive species of the onion tribe, called by botanists Allium sckcenoprasitm. It is not bulbous ; but grows in thick tufts, producing an abundance of slender delicate leaves, having the true onion flavour, and very useful in dressed salads, when small green plants of the common onion are not to be had. There is, or always should be, a small bed of chives in the herb border, the leaves being often useful in cookery, as well for garnish- ing as for salads. There should also be a few pots of chives kept in every garden, in order to be placed in a hot-bed or hot-house, to afford a supply during winter. In the open ground they require to be frequently cut off, to induce a fresh growth of leaves. Chives are propagated by divisions of the root, and like a shady situation. CHL^ENIUS (Bonelli). A very extensive genus of Coleopterous insects, belonging to the section Pen- tamera, family Carabidcc, and sub-family Harpalldes, and to that subdivision in which the anterior tarsi alone of the males are dilated, the basal joints being large, square, or rounded, or the Patellimancs of Dejean. The palpi are rather long, with the terminal 31 joint slightly oval, squared off at the tip ; the tooth at the middle of the chin is bifid, and the three basal joints of the males are dilated. These insects are amongst the most elegant species of the family, being- ordinarily of a fine opaque green colour, and clothed with a down, whence their generic name ; some few species have, however, the body smooth and shining. They appear to be distributed over the whole surface of the globe ; none, however, are yet recorded to have been found in New Holland. They emit a very powerful and disagreeable alkaline odour. The Count Dejean has described sixty-six species in his " Species General," but in his new catalogue there are llo belonging to this genus. There are seven or eight British species, of which the Carabus marginatris, Linnaeus, ( Vestitus, Fabricius,) is the most abundantly met with. Their habits do not materially differ from the other allied genera. CHLAMYPHORUS. A genus of mammalia belonging to the order Edentata; and nearly allied to the armadillos, though different from them in many respects. The characters are : ten teeth of uniform size ; five toes on each of the feet, with nails on the fore feet very strong, crooked, compressed laterally, and forming very powerful weapons either for digging or for defence. The back is covered with a succes- sion of scaly pieces ranged transversely ; but there is no shell either at the anterior or the posterior part, as is the case with the armadillos. These pieces are attached to the spine only. The animal is not above five or six inches long ; like the rest of the tribe it is found in the interior of South America, and it spends the greater part of its time under ground, for bur- rowing in which its powerful claws on the fore feet are well adapted. CHLAMYS (Knoch). A genus of coleopterous insects, belonging to the section Tetramcra, and fa- mily ChrysomelideB, comprising a considerable number of minute but curious species from Brazil, having the body short and very irregular above, the head verti- cal, the antennae short and serrated, and the labial palpi furcate. Two excellent monographs of this in- teresting genus have been given by Messrs. Kollar and Klug ; some of the species have the appearance of morsels of rough precious stones, being of a rich metallic colour. In their habits they are, probablv, herbivorous, like the majority of the family to which they belong. CHLENACE^E. A natural order of dicotyledo- nous plants, containing five genera and eleven known species. Many authors consider this order as allied to the mallow tribe, on accountof its involucrated flowers, and monadelphous stamens. Jussieu however thinks that, in consequence of its petals coalescing at the base, and its seeds being albuminous, it bears an afti- nity to Ebenacece, or the ebony family. The plants of the order do not seem to be sufficiently well known to enable botanists to determine their exact position in the natural system. The essential characters of this order, as given by Decandolle, are : involucre one to two-flowered, persistent, varying in form and texture; sepals three, small; petals five to six, hypo- gynous, broad, and sometimes slightly coalescing at the base; stamens sometimes numerous, at other times only ten ; filaments somewhat combined into a tube at the base, or adnate with the tube of the petals ; anthers two-celled, roundish, adnate or free ; ovary single, three-celled ; style one, filiform , stigma triple; capsule three-celled, or by imperfection only CHLID AN THUS-CHL ORION. one-celled ; seeds solitary or numerous, fixed to the centre ; albumen fleshy or horny ; embryo green, central ; cotyledons fbliaceous, waved. The plants belonging to this order are small trees _or shrubs, with alternate, stipulated, entire leaves, and paniculate or racemose flowers. They are almost all natives of the Island of Madagascar. The genera of the order are Saccolcena, Leptoleena, Schizoltena, and Rhodokena. To these Decandolle has added the East Indian and Mauritian genus Hugonia, which he considers allied to the order Chlenacece, but differing from it in being destitute of an involucrum to the flower. This genus is also allied to Malvacece and Syttneriacece, but is distinguished from them in having an imbricated, not a valvate, calyx. Very little is known in regard to the properties of the plants of this order. Lcptoltena mult'iflora, and the species of Schizolcena, are handsome small trees with fine flowers, while Rhodol&na altivola is a climbing shrub, with large purple flowers. The genus Hugonia was named by Linnaeus in honour of Dr. Augustus John Hugo, of Hanover, who was a great friend of Haller. Hugonia mystax, a native of Ceylon and Malabar, is a slender shrub twelve feet high, with numerous short leafy branches, each of which bears about its middle a pair of remarkable revolute spines. The resemblance of these to a pair of moustaches, is said to have given origin to the specific name mystax. The plant bears yellow flowers, and a shining fruit, containing a red tasteless pulp. The wood has a reddish -brown colour, and possesses an aromatic odour. The root has been applied exter- nally to inflammatory swellings, and also to the bites of the hooded snake (coluber nnja]. Internally it has been recommended in worms and the febrile diseases to which children are liable. CHLIDANTHUS (Herbers). An ornamental and highly fragrant bulbous plant, introduced from South America in 1820. Linnaean class and order Hexandria Monogynia; natural order Amaryllidece. Mr. Sweet observes of this plant, that it requires no water when not in a growing state ; and if planted in the open borders in spring it will flower in the sum- mer, but must be taken up in autumn, and kept dry through the winter ; or if left in the ground requires covering from frost. CHLORA (Linnaeus). A genus of two annual plants, one of which, C. pcrfoliata, is a native of Britain. They belong to the natural order Gentianeee. CHLORANTHE^I. A natural order of dicoty- ledonous plants, containing three or four genera, and a few species. It is nearly allied to Piperaccce and LaunnccE, but differs from these orders in the absence of a sac to the embryo, and in having a pendulous ovule, and opposite leaves with intermediate stipules. The following are the botanical characters of the order: flowers naked, spiked, perfect or unisexual, subtended by a scale ; stamens lateral, if more than one, connate, definite ; anthers one-celled, bursting longitudinally ; filaments slightly adhering to the one- celled ovary; stigma simple, sessile; ovule pendu- lous ; fruit a drupe, indehiscent ; embryo minute, placed at the apex of a fleshy albumen, with an inferior radicle. The plants belonging to this order are herbs or under shrubs, with jointed stems, opposite simple leaves and terminal green flowers. They are incon- spicuous, and are not considered as ornamental in gardens. They are found in tropical regions, and inhabit the hot parts of both the East and West Indies, as well as South America. They have ge- nerally an aromatic taste, arid possess stimulant properties. The chief genera of the order are Chloranthus, Hedyosmum, and Ascarina, Chloranthus is the genus which gives name to the order. The whole plant of Chloranthus oj/icinalis has a fragrant aromatic odour, which is lost by drying. The roots of the plants however retain, even when dry, a smell like camphor, and have a bitter aromatic flavour. They possess heating and stimulant pro- perties, and may be used in place of snake-root in promoting the action of the skin and kidneys. The root of Chloranthus inconspicuus has the odour of seneka root, and is said to possess similar qualities. The leaves of the plant are used in decoction, for the cure of intermittent fever. CHLORANTHUS (Swartz). A genus of three Chinese herbs and under shrubs, bearing green- coloured inconspicuous flowers, but having an agree- able scent, for which they are kept in stoves and propagated by cuttings. CHLORION (Latreille). A beautiful genus of hymenopterous insects, belonging to the division Fos- sorcs, and to the family Sphcgidae, or sand-wasps. The body is rather long, highly polished, and me- tallic ; the head broader than the thorax ; the an- tenna? inserted close to the mouth, and the second submarginal cell narrow, especially near its union with the marginal cell ; the tarsal claws have a tooth near the middle. These splendid insects are above the middle size, and owe their generic name to the brilliant metallic green colour with which they are adorned. The habits of one of the species of this genus, Sphcx lobata, Fabricius, were observed by M. Cossigni, who states that it is a rare insect in the" Isle Bourbon, although very common in the Isle of France ; it flies with rapidity, entering the houses, flying about the window-curtains, and creeping into their folds ; when settled it is easily caught : but great caution must be used, as it is provided with a sting even more power- ful than that of the bee, this fly protruding its weapon to a greater distance than the bees ordinarily do. In the Isle of France the domestic bees are not observed, although they abound in the woods of the Isle Bour- bon ; their rarity in the former instance being attri- buted to the presence of the chlorions, which drive them away. M. Cossigni observed an encounter be- tween a cockroach and a chlorion. After regarding each other for a moment, the latter pounced upon the blatta, seizing its head with its jaws, and curving its body so as to sting the belly of the cockroach. When it had effected this, it dismounted, quitted its victim until the poison which it had introduced into the wound should have begun to operate, when it re- turned, seized it by the head, and, dragging it along backwards, deposited it in a hole in the wall. When its prey is too large to enter the aperture, the chlorion deliberately clips off its wings and wing-cases, and even its legs, so as to enable it to force it into the bur- row. The object of this slaughter is the laying up of a sufficient supply of food for the future progeny of the chlorion ; hence, as is generally the case in in- sects, the task devolves upon the females, and, indeed, it is this sex alone which is provided with the powerful sting which is so important an instrument in the ope- ration. We have detailed a somewhat similar course of proceeding in the CEHCJSRIDES. See our article upon this group. CHLOROPS — CHOANITES. 83 CHLOROPS (Me-igen). Osciiiis, Latreille. A genus of dipterous insects, belong-in": to the section Athcric/'ra, and family Muscidce. The head is nearly spherical ; the legs are of moderate size and thick- ness, and the body short and not filiform ; the an- tennae are short, and have the seta not branched. These insects, which are of small size, are amongst the most obnoxious of the diptera, attacking various kinds of corn, and almost equalling in their ravages the Cecidomyue. They are of small size, smooth, po- lished, and of a black colour more or less variegated with yellow. To this genus belong the Musca Frit of Linnaeus, and the Musca pumilionis of Bierkander, t>»xjiher with upwards of twenty other British spe- cies. The first of these insects, although stated by Messrs. Kirby and Spence not to have been disco- vered in Britain, is doubtingly introduced by Mr. Stephens into his Catalogue of British Insects. This fly, according to Linnaeus, occasionally destroys in Sweden not less than a tenth part of the crops of bar- ley, the loss being estimated at 100,000 golden ducats. The mischief is effected by the insect getting into the ears. An in cresting account of the chlorops pumi- lionis is given by Mr. Markwick, with additional ob- servations by Mr. Marsham, in the second volume of the Linnaean Transactions. This insect was at first considered as the Hessian fly, and no small alarm was produced in consequence thereof ; but the latter author, by pursuing a series of observations by which the real species was determined, proved the incorrect- ness of such a supposition. Early sown wheats are especially liable to the attacks of this fly, the grub of which feeds within the principal stem, just above the root, thereby entirely destroying it ; the root, how- ever, throws out side shoots, so that the injury is not so great as it was at first supposed that it would have been. The perfect flies, as we have stated in our article on the Cecidomyiae, abound in the autumnal months*, swarming in our apartments, so that, from the short-lived existence of dipterous insects in the per- fect state, it seems necessary that, as the flies are pro- duced from the early sown wheat in May, there should be an intermediate generation to produce the autumnal brood ; direct observation is, however, required upon this point. This insect is under a quarter of an inch in length, the thorax having two lateral yellow lines. The maggot is white and fleshy. It is at the period when the wheat is about six or eight inches above the ground (as we learn from a friend who has lately reared some of those destructive insects), that the chief injury is committed. CHLOROXYLON (Dccandolle). A lofty East Indian tree, called Siuictenia cldoro.vylon by Roxburgh. It is the green mahogany of the east, and as useful timber is estimable for many purposes of buildinsr. Chloroxylon is also the specific name of one of the West Indian laurels. CHOANITES. A name given by Mr. Mantell, in his Geology of Sussex, to a genus of fossil zoo- phytes, which are very numerous, and appear to hold an intermediate place between the Alcyonia, properly so called, and the Ventriculites. They are distin- guished from the former by their having a central cavity in their upper part, and, from the latter, by their being without an external reticulated integu- * During the autumn of 1834, they literally swarmed ii mpa tments. even in the immediate environs of London. NAT. HIST. — VOL. II. ment, &c., and possessing a very slight degree of contractile power. Their forms are various, being enerally either funnel-shaped, spherical, globular, or subcylindrical, having a central opening in their superior part, and appearing to have been originally composed of a parenchymatous substance, capable of imbibing moisture, and of contraction in a slight degree. The base was fixed. The Alcijonimii Jicus of Linnceus may be considered as the type of this genus. Parkinson, in his Organic Remains, describes this zoophyte as follows : — " It is of the form of a fig, being attached to rocks by branches proceeding from its smaller end ; the upper part is a little flattened, and has a cavity in the centre. Its colour resembles that of tobacco, and its parenchymatous substance cannot be compared to any thing better than to nut-galls when well dried." Org. Rem., vol. ii., p. 96. The remains of this genus, which were formerly indiscriminately placed among the A/cyonia,\\ere first noticed by M. Guettard, at Verest, and at Mont Richard, in Touraine, and were described by him in a paper published in the Memoirs of the Academy of Sciences of Paris, 1757. He observes that they are of a globular form, having in many examples the base elongated into a pedicle. In the centre of the superior part is a circular opening, generally filled with the substance in which the fossils are embedded. The cavity is larger in its upper part than in the lower, and is con- tinued almost to the pedicle, in some specimens ap- pearing even to pass through it. From the circum- ference of the opening, lines may be traced that not only pass over the whole of the spherical part (where they form striae more or less distinct), but also pene- trate the substance of the zoophyte. There is seldom more than one opening, but instances have occurred in which three have been found. Very accurate representations of these fossils are given in Parkin- son's Organic Remains, vol. ii., pi. 9, figs. 1, 3, 4, 6, 8, and pi. 11, fig. 8. Three species are described by Mantell. The first of these, the Subrotundus, is that generally termed by collectors the Ficoid alcyonite, from its supposed resemblance to the fig. The surface is smooth, and entirely without markings, and the cavity nearly circular. The second, the Flexuosus, is cup-shaped, the margin of the central depression being marked with flexuous indentations. The radical processes are all long and fibrous. This species is very rare, and, as well as the former one, is found in the Upper Chalk, near Lewes in Sussex. The Konigil is the third, and is described as " inversely conical, externally marked with irregular fibres, some of which penetrate into the substance of the fossil, and terminate in openings on the inner surface. The central cavity is cylindrical, deep, and narrow, and the base fixed by the radical processes." This spe- cies is generally enveloped in large irregular flints, which exhibit but slight traces, externally, of the body which they inclose. The superior part pre- sents a convex surface, with a cylindrical body in the centre, whence interrupted fibres ramify in a radiating manner towards the margin. Numerous perforations may also be observed at the base, which, without doubt, afforded a passage for the radical processes. They are found in abundance in the loose flints beneath the turf, near Lewes race-course, and appear to have been of frequent occurrence in the upper beds 0 CHOCOLATE NUT-CHONDROPTERYGII. of the chalk, although they are now very rarely found in the quarries in that neighbourhood. CHOCOLATE NUT is the Ttieobroma cacao o! Linnaeus. See THEOBUOMA. CHOLEVA (Latreille). A genus of coleopterous insects, belonging to the section Pcjitamcra, and family Silphidtc. This genus, together with those of C'a- tops, Ptomaphagus and Myl&chus, form a small group, distinguished by their small size, and great agility ; the antennae with the club five-jointed, the eighth joint being very minute, and the elytra rounded at the tips. Mr. Spence has published a monograph upon the group in the Linncean Transactions. The insects are of dark and obscure colours, frequenting dry bones, putrid fungi, and vegetable matter in a state of decay. There are numerous British species. CHOMELIA (Jacquin). West Indian shrubs, formerly culled Lrora by Lambert and Swartz. Lin- naean class and order, Tctrandria Mbnogynia ; natural order, Rubiacea;. Generic character : calyx tubular, limb four-cleft, recurved ; corolla tube long, cylindri- cal, limb in four divisions, spreading points of the divisions acute ; stamens with short filaments inserted in the tube ; anthers linear, and somewhat prominent ; style filiform ; stigma in two spreading processes ; drupe oval, containing a four-furrowed two-celled nut, each cell one-seeded. This genus being nearly allied to the ixoras, also partakes of their ornamental character. CHORAGUS (Kirby). A minute genius of British coleopterous insects, of whose family ento- mologists are at variance. It is of an ovate form, with the head deflexed, the antennas long and termi- nated by a club ; the legs are short and of a moderate thickness, nevertheless the insect possesses the power of leaping in a remarkable degree. Mr. Kirby, by whom it was first described, thought it allied both to Cri/ptocephalus (from the length of the antennae and form of the body), and Cis (from the former being clubbed). Mr. Stephens places it amongst the PlinidcE, whilst M. Robert has recently figured it as an Aiithribus, a genus allied to the Bruchidce. It is found amongst grass and low herbage, but is very rare. CHORIZEMA (Labillardiere). A genus of beautiful shrubs, natives of New' Holland. Linnaean class and order, Dccandria Monogi/nin ; natural order, Leguminoscc. Generic character : calyx two-lipped, upper one cleft, lower one trifid ; corolla keel belly- ing, wings short, style short ; pod swollen, many- seeded, nearly sitting. These are extremely neat greenhouse plants. The C. Henchmannii deserves a place in every collection. They are propagated by cuttings. CHRISTMAS ROSE is the Hellebonu niger of Linnaeus. One of a herbaceous family of plants in- digenous to Europe, and long introduced into gardens on account of their early flowering. The whole of the hellebores are said to contain poisonous principles in a greater or less degree, though some of them are very fragrant. The flowers generally appear before the* leaves, and are some of the first gems of the spring. They are propagated either by dividing the root or by seeds. CHRIST'S THORN is the Zyziphiu spina Christi of Willdenow. It is a native of Egypt, and is culti- vated in our greenhouses, and easily increased by cuttings. CHROMIS. A genus of spinous-finned fishes belonging to the family Labroidrs. Their general characters are : their lips and intermaxillary bone* contracted ; a single dorsal fin with two produced filaments, teeth set like those of a card on the jaw bones and the palate, their lateral ones intercepted, the ventral fins produced in long threads. There are numerous species, several of which are occasionally found in the British seas. They are not of large size, but they are esteemed as food. For some detail of them, the reader is referred to the article LABROIDES. CHONDROPTERYGII (CARTILAGINOUS FISH- ES), An order or rather sub-class of fishes which differ so very much in many of their essential characters from the rest of the finny tribes, that naturalists have sometimes described them under the name of reptiles rather than fishes. But still, how much soever they may differ from the other inhabitants of the waters, they are decidedly fishes, only it is not easy to trace a gradation either from them to the others, or from the others to them. In some parts of their organisa- tion they are no doubt inferior to the bony fishos, but there are some others in which they are decidedly superior. They differ greatly in the several divisions of the sub-class ; but they all possess that general cartilagi- nous texture of the bones, on account of which the name has been given them. This character varies much however in the different genera, so that it is not possible to frame a general description, so that it shall be strictly applicable to any one species. In general, we may say that they have some resemblance to that division of the soft-firmed fishes, to which Cuvier very accurately applies the name cf p/eclog- nathes or " soldered jaws" — because these fishes have the bones of the mouth united to each other, and consequently comparatively little motion of that organ. There is another approximation in that family to the sub-class now under consideration, namely, a tendency to produce upon the skin, not scales as in the other bony fishes, but grains or tubercles of osseous matter. The chondropterygii have all the bones, forming the cranium or cavity containing the brain, united into a single piece, but still there are markings which indicate portions resembling those that are united by sutures in other fishes, though in some these mark- ings are almost entirely obliterated, and the whole skull consists of one case of flexible bone. The vertebral column may be said generally to consist of one single flexible piece, though in this also there are differences, some having articulations marked throughout its length, and even tolerably distinct apart, while in others, as in some of the cyclostoma, "round mouths," or suckers, there is scarcely any indication of a joint even by a simple marking ; so that these may be regarded as, in their skeleton at least, being at the very bottom of the scale of verte- brated animals, and connecting them with some of the most simply formed tribes in the whole animal kingdom, the myxine or hag being as much like a slug or leech as a fish, although it has still the gene- ral character and economy of a vertebrated animal. But it is in the general texture of the bone, rather than its form, that the distinguishing character of these fishes consists. In all other vertebrated animals the bones are made up of plates, and these plates of fibres, which extend in the direction of the length of the bone, so that the bone is much more easily split in length than broken across, whereas in the chon- CHONDROPTERYGII. 35 dropterygii, whatever of osseous matter, or earthy salts, is funned in the cartilaginous matter, forms in grains, which are detached from each other without any appearance of being organised in any direction. The bones, even of those animals which have the skeleton hardest and most perfect when mature, are cartilaginous when they are young, and they ossify gradually, requiring a longer or shorter time in dif- ferent races of animals ; but, when ossification begins, always begins at points, and proceeds from those points as centres, in lines of definite arrangement, the characters of which are worthy of more attention than they have hitherto received. Thus there is in the cartilage of these animals, a principle by means of which it can organise the earthy parts of the bone, as well as produce them, whereas, in the fishes under con- sideration, this principle seems to be entirely wanting ; and therefore, though the general cartilaginous basis of the bone may be considered as a product of organi- sation, the hard matter which may afterwards be imbedded in it, is not so imbedded in consequence of any particular law of organisation. In this respect therefore, we may with perfect correctness say, that these fishes are a stage lower in the structure of their bones than any other verteb rated animals. It seems also that their cartilage is differently formed. The car- tilage of the others is to a considerable extent fibrous, though the fibres are not easily perceptible, in conse- quence of the closeness of their union ; and we may suppose that the reason why the bony matter in this sub-class of fishes is not organically arranged, is the absence of this structure in the cartilaginous basis. Therefore, though the term "cartilaginous" answers very well for distinguishing them from other fishes, we must not suppose that they have the same kind of cartilage as the others only without the bony mat- ter in it ; for their cartilage is not only really but necessarily different. If it were the same in substance and in arrangement, it would be impossible not to suppose that it would ultimately ossify into the very same kind of bone. If we were not to conclude that the same preparing substance would, and must, under the same circumstances, produce the very same result, then we could come to no conclusion what- ever, and there would be an end to natural history as a science. Imperfect as the bony structure of these fishes thus seems, it has its advantages. They move more freely than animals with stiff bones ; they are much less liable to injury ; and so far as we know, they are exempted from old age, from decay, and probably from death, except by casualty. In all cases where the bones of the vertebral co- lumn are stiff, the motion of the joints is confined to certain directions only ; and though some vertebrated portions, as in the necks of many birds, and more especially in the chelonia, which have hard shells, have very beautifully formed joints, and admit of a wonderful degree of flexure, yet in them the flexure is produced by every different joint being bent in a different direction, there being as many centres of motion as there are joints, and consequently a very complicated apparatus of muscles for moving them. The bones of the true serpents (we are of course speaking of the vertebral column only), and those of bony fishes, afford instances of motion which is more free and more general in its direction ; but still the principal motion is referable to a definite plane in the clody of the animal. That of the serpents is vertical, passing through the middle of the back and the belly, and there is generally a distinct mesial line along one or both. The bony fishes again are articulated, so as to have their principal motion in the horizontal plane passing through the middle of the sides, which are generally marked by lateral lines. The joints in these are without processes, upon which a particular motion can be performed as on a centre, for they consist of two hollow conical cups, with their lips applied to each other, and their cavi- ties filled with cartilaginous substance, so that each of them may be considered more or less as a universal joint, though this is modified in different species, in such a manner as best adapts them to their habits ; a bone of this kind is obedient to the action of the general muscular mass in which it is embodied, and does not need detached muscles for the motion of every single joint, attached at each extremity to one of the bones which meet at the joint, in the same manner as in animals which have the bones articu- lated upon each other by means of processes and cavities. The muscles of fishes act between the bone and the skin, as their two principal points of inser- tion ; and as the skin is supported externally by the weight of the element in which the fish moves, much less muscular exertion is required to produce motion, than in animals which have the bones with regular joints. In the cartilaginous fishes, this facility of motion is communicated to the whole of the vertebral column, so that they can move with still less of muscular effort than the true fishes. Thus they have great command of themselves in the water, without much exhaustion of their system ; and as there is at the same time no positive limit to the growth of their bones, they are exempted from old age and decay. This leads us to another peculiarity of their struc- ture, their respiratory system. The quantity is proportionately less than that of bony fishes, and their breathing apparatus is of more simple structure. In consequence of this, the whole functions of life in them are carried on with less exhaustion of the sys- tem than those of the other fishes ; and thus, while their body is less worn by the operation of living, it requires less renovation, the principle of life in it is more durable, they can bear abstinence for a greater length of time, can feed more voraciously when they do feed, and more of the substance of their food can go to the increase of their size. These particulars vary much in the different divisions or orders into which they may be divided, and also in the subdivi- sions, but still they, to some extent, apply to the whole. There is this further to be remarked on them gene- rally, that their organs and manner of reproduction are much more perfect than those of the other fishes, that in these respects they bear a considerable resem- blance to reptiles ; and some of them have even a physiological, though not a structural, resemblance to the marsupial mammalia. In describing them according to their feeding apparatus, which, however, is much less satisfactory in the case of fishes than in that of any other vertebrated animals, the most re- markable circumstances are the absence of maxillary and intermaxillary bones for supporting the teeth. But the teeth, though they are without bony sup- ports, are not the less powerful ; for some of these fishes, as the shark for instance, have more formidable mouths than any other animals. The teeth are . C a CHRYSALIS. moveable; and as they are generally in several rows, they can hold on with one part, and cut and tear with another ; and if we except those fishes which feed upon Crustacea or sea-weed, they are per- haps the only ones which divide their food by the action of the mouth. The skin is a very important part of the structure of these fishes, and may be said to contribute almost as much to support them in their motions as the bony part of their structure. Indeed the skin is almost the only part in which any substance approaching to the character of bone is formed. Some of them pro- duce large plates as in the sturgeons (see the article ACCIPENSER), others hooks and spines, some of which are very formidable weapons, and others tubercles of various forms and sizes. The various species of sha- green which is used for covering boxes and various other articles are the skins of sharks. These bony appendages are exceedingly hard in their consistency ; but whatever may be their form, they partake of the general character, which \ve have already alluded to as distinguishing the internal bones — they do not exhibit a fibrous structure, but are uniform throughout; and though it is difficult to divide them in any parti- cular direction, they are equally divisible in all. These fishes are divided into two sub-orders, those which have the gills fixed, and those which have the gills free. WITH FIXED GILLS. In these the gills adhere to the skin, or rather to the integument of the sac in which they are contained, instead of being loose at their posterior edges, as is the case with other fishes. The water does not therefore pass through the gills of these fishes as it does through those of others; neither have they any gill-lid, or operculum, by the action of which they carry on the operation of breathing. They have between every two fringes or leaves of the gills, an opening for the admission of water, and the outer edge of each gill is supported by a cartilaginous arch imbedded ia the flesh, between the openings ; and it is by means of the muscles acting on this arch, that the process of breathing, which is a very slow one, is carried on. The genera and species of this order are much more numerous than those with free gills. They consist of two families, PLAGIOSTOMUS, "oblique mouth," or "cross mouth," the mouth being in the form of a slit under the snout, which generally projects a considerable way in front of the opening, arid the mouth, from the absence of jaw-bones, admits of a great deal of motion; and CYCLOSTOMUS, "round mouth," from the mouth being in the form of a sucker, or capable of turning backwards so as to be on the same plane all round. Some notice of each of these families will be given under its name in the order of the alphabet. WITH FREE GILLS. These have their gills free at the one extremity, as is the case in ordinary fishes, and they have only a single gill opening, for allowing the water to escape. This opening is furnished with a gill lid; but without any flap. This sub-order consists of four genera, though all these may be in- cluded in one family, the sturgeon family. See STURIONID^:. Of these two orders or sub-orders, those with fixed gills may be considered as the most typical ; but both stand so distinct from the rest of fishes, that, with the exception of the partial resemblance to plectog- nathes above alluded to, they must be considered as forming, not a subdivision of fishes considered as one class of animals, but as a distinct class of fishes, which hold a very peculiar place in the structural system of animals, and also from their numbers perform an im- portant part in the living economy of the waters. We must not suppose that there is any thing out ot nature, in there thus being two distinct classes of vertebrated inhabitants of the waters, any more than that there should be different species ; for we have a similar division of mammalia ; the marsupial animals being as distinct from the other mammalia, as the chondropterygii are from the other fishes. We have mentioned that there are some points of relation be- tween those second classes of mammalia and of fishes, and one would be almost led to believe that they are portions of a different creation from the other classes, which they resemble in their common eco- nomy and habits. It is exceedingly difficult, however, to trace the analogies between sea and land animals, not only from the great ignorance in which we must for ever remain as to the details of what goes on in the deep, but because many links in the chain are wanting. CHRYSALIS or AURELIA. Under these terms is designated the pupa state of lepidopterous insects. Having already, in our article AURELIA, given some account of the cause of the application of these terms to this state, and in one article, BUTTERFLY, detailed the peculiarities of the chrysalides of the Papilumida>, we shall here briefly notice some general circum- stances relative to chrysalides in general, and to those of moths and hawk-moths in particular, reserv- ing to the article COCOON our account of the con- struction of those curious envelopes in which the insect is often in this state inclosed. The pupa) of lepidopterous insects entirely differ from those of every other order of insects, a circum- stance of some interest as well as peculiarity, since in other instances we find the pupae of several orders exhibiting the same general form. In the Lepido- ptera, however, the various organs of motion of the future insect are laid along the breast and sides, but. are folded up under a hard skin, whence they are much less distinctly perceptible than in the pupae of other insects. Linnaeus has termed this an obtected pupa. In general lepidopterous chrysalides are of an oblong-oval form, obtuse at the head, and gra- dually becoming narrow towards the tail ; but in some moihs, as in the Hornby* luna, the form is shorter, and obtuse at each end. Under this form the insect appears neither to have legs nor wings, it seems even destitute of life, taking no nourishment and appearing like an unorganised mass, the only sign of life being a slight occasional twitching of the hind part of the body. The outer covering appears of a cartilaginous nature ; it is commonly smooth, but in some few instances it is hairy. From the blunt extremity of the body are to be observed various small and narrow compartments, arranged like the bands of a mummy. These are the coverings of the legs and antenna?, disposed along the breast, the part from whence they seem to arise is the head, which is covered by a piece termed the Ccphalothcca. On the outside of these narrow bands are to be observed two broader scales, which, covering the wings, are termed Pterotheca, arising from the opposite side to the breast, and which is the covering of the thorax, or Cytotheca. This is followed by the abdomen-case, Gastrotheca. The chrysalis, upon quitting the exuvia of the caterpillar, is soft and tender ; by degrees, however, its external envelope becomes hard and friable. Moreover the surface of the body is at first moist- ened with a viscid fluid which exudes from beneath the wings, and the other parts which are inclosed between these organs, and which becomes thickened and hardens rapidly, and in so doing glues together the contiguous parts, which are consequently now inclosed in an additional envelope, this taking place within twenty-four hours after the change ; at the same time also this fluid not only loses its transpa- rency, but also acquires a colour. Previous to the hardening of this fluid it is easy to observe as well as to separate the various external organs of which the future butterfly is composed, as the anteniiie, legs, wings, &c. there is this difference, however, between the chrysalis and the imago, at least of the butterflies ; in the former state one pair of wings, the upper, are alone to be observed, the second,°or inferior pair, being hidden beneath them, the inter- mediate space in the pupa being filled with this gummy matter, by which they are at length glued together; whereas in the butterfly (but not in the moths, except during flight) the lower pair of wings are exposed, even when the butterfly is at rest upon the bosom of a flower. Reaumur has divided chrysalides in general into two great divisions, namely, those which, from having various angular projections upon the body, he has termed angular chrysalides, and those in which the body is smooth and unfurnished with these projec- tions, and which may be termed conical chrysalides, but which Reaumur calls " feves ;" and it is a curi- ous circumstance, that all angulated chrysalides produce butterflies, whilst from the conical chrysa- lides, with a few exceptions, the various tribes of moths and hawk-moths are produced ; these excep- tions being confined to the small butterflies, belonging to the family Lycamida:. Moreover the chrysalis of the orange-tip butterfly (Mancipium car da mine's) seems intermediate between the two groups, having the body boat-shaped, with a spindle-formed process arising from the head, as well as the tail. There is a great difference in the situation of the prominences and angulated projections, upon the body of the chrysalides belonging to the first of these divisions, and in some of the old works of natural histurv, we find the representations of them fancifully converted into the singular profile of the human face, the dorsal prominence forming the nose ! Amongst the conical chrysalides, there are also various differences to be observed ; we shall, however, only notice those offered by the sphinx family, in which the tongue, which in the perfect state is exceedingly long, is inclosed in a thickened cylindric proboscis, which stands off from the breast, and within which the tongue is curled up ; whilst, in the genus Calophosia, Stephens, a provision of a different kind is made for the unusual k'ngth of the organ, by the tongue-case being recurved upon the breast, in which respect it ap- proaches the shark moths, Cucullia;. In our article BUTTERFLY, we have alluded to the incorrectness of the fanciful notions entertained by the old naturalists, that insects in their progress to tiie perfect state underwent a series of real meta- morphoses. In like manner we may notice, as conveying' an equally incorrect idea, that the bursting forth of the butterfly has been adopted as an illus- tration, fitting to convey a token of one of the profoundest mysteries of our Holy Religion. CHRYSANTHEMUM. 37 Oh, start not ! on thy closing eyes Another day shall still unfold, A sun of milder radiance rise ; A happier age of joys unfold. Shall the poor worm that shocks thy sight, The humblest form in nature's train • Thus rise in new-born lustre bright, ' And yet the emblem teach in vain ? The idea is highly poetical, but the simile is not correct when the changes undergone by " the poor worm" have had all of the marvellous stripped from them by the assistance of direct observation ; and yet these changes are not, on that account, the less wonder- ful. To them, indeed, may well be applied the cele- brated words of the poet—" Truth is stranger than fiction." The body of the caterpillar consists of twelve segments, exclusive of the head and anus, and on each side of the 1st, 4th, 5th, 6th, 7th, 8th, 9th, 10th, and 1 1th of these segments, a small oval spiracle or breathing pore is to be observed, making together eighteen. In the pupa, notwithstanding the great alteration which has taken place in the size and dis position of the segments, we notice, besides the head, first, a small, nearly square, piece, being the remains of the first segment, having, on each side, a small breathing pore ; next, a large dorsal piece, giving rise to the large anterior wings, which is the second seg- ment; then a short dorsal piece, giving1 rise to the second wings, being the third segment ; after which, follows another short segment, of which the spiracles are not observable, which is succeeded by seven spi- raculiferous rings; then comes another ring, with- out spiracles, and the body is terminated by a plate covering the anal organs. This description is taken from a living male Chrysalis, of the splendid large Emperor moth, Paconia major, an inhabitant of France. The Chrysalides of various moths exhibit a singular circumstance not hitherto satisfactorily accounted for, but which present an interesting instance of that parental care, " which nature so conspicuouslv mani- fests towards the most insignificant (if any'can be called such) of her productions." The small Eggar moth, Eriogaster lanestris, is one of the most remark- able of these species, — doomed to a regular appear- ance, in the winged state, at the termination of the cold and nngenial month of February, nature (that it may not fail and become extinct) reserves a small portion of it annually, in the pupa state, until the February following that of its pupation, and some- times even until the third occurrence of that frigid month, denying their emancipation all the intermediate time, and thus effectually securing, by these unusual means, the safety and perpetuation of an animal, small it is true, but whose annual existence, at that incle- ment season, in the winged state, is probably of more consequence in the intricacy of its great Creator's plans than we are at present aware of, although He constantly exposes it to the dangerous vicissitudes of winter; for Each shell, each crawling insect, holds a rank, Important in the plan of Him who framed This scale of beings, holds a rank, which lost, Would break the chain, and leave behind a gap, Which nature's sell' would rue."—Lepiduptera. Britannica. CHRYSANTHEMUM (Linnaeus). An extensive genus of herbaceous perennial and annual plants, valued for their large showy flowers. LinnEeari class and order, Syngcncsia superflw, natural order, Coin- 88 CHRYSIDID^E. Generic character : anthodium hemisphe- lical, scaly ; scales with scarious margins ; receptacle plain and naked ; seeds oblong and angular. The geographical distribution of this genus extends over all the northern hemisphere, from the British isles to Kamschatka, and from Siberia to Asia Minor. One of the British species, C. scgetum, was formerly a troublesome weed in corn, insomuch that land subject to it was lower rented than that where the yellow weed was unknown. By careful hand-weeding, how- ever, the plant is now almost banished from all well cultivated fields. Several are admitted into the flower garden ; and since the introduction of the Chinese half shrubby species, every greenhouse, garden, and court-yard, are ornamented with them. Few plants have engaged the attention of florists more than this, and they are now as much admired, and as much cul- tivated in England, as they are in China. Two monographs have been published of the C. Sincnse, the first by J. Sabine, Esq., S.H.S. of London, and the second by the late A. H. Haworth, Esq. Ac- cording to Mr. H., there are above fifty different species or varieties, all of them handsome, and some of them splendid flowering plants. They are what are called half-hardy, that is, if planted in the open ground, their stems, like those of other perennials, are killed down to the ground in winter ; but the aggregated roots survive with but a very slight pro- tection, whence the flowering stems of the next summer are produced. There are various methods of cultivating the chrysanthemum. The easiest, perhaps, is to plant them close under a wall, to which the stems are trained during their growth. They may also be planted singly in the flower borders, and the shoots kept tied to a stake as they advance in height. But, as the plants flower very late in the season, a circum- stance for which they are much prized, they require assistance from heat, either reflected from a wall, or applied in some other way, in order that the flowers may be sufficiently forsvard to blow before the frosts set in. Young shoots separated from the old stool, or cuttings made of the earliest shoots, are soon esta- blished as individuals, and in this state grow much more luxuriantly tlian if they had been left on the parent stool. These young individuals, being more robust in habit, produce larger flowers, and these in greater abundance. As the flowers are terminal, that is, produced on the points of the shoots, they cannot appear until the stem has gained its full height, which is sometimes, when trained to a wall, six or eight feet ; and when allowed to grow so tall, and kept in pots, are very inconvenient in a greenhouse. To counteract this tendency to run up, and to have low bushy plants and a plentiful bloom, a judicious practice has been had recourse to by some florists with the best effect. This is by layering the strongest shoots, in the months of June and July, into pots of light rich com- post, plunged in the ground at a proper distance round the stool, and in a shady place. The point of the layered shoot is thus furnished with a new system of active roots, which are competent to perfect the further elongation of the shoot, with its terminal bouquet of flowers ; and these, though quite perfect as to form and colours, are never quite so large as would have been borne by the shoot if it had not been layered at all. Each stem bears a branched head of flowers ; and if a few only are wished to be as large as possible, they may be thinned by cutting off all the inferiors before they are too far advanced. There are other ways of dwarfing the chrysan- themum besides layering them as above described. Starving them in poor sandy soil, in diminutive pots, and allowing but short supplies of water, will chock luxuriance ; but this is always at the expense of the beauty and size of the flowers. CHRYSIDID.E (Leach). A family of hymeno- pterous insects, belonging to the section Pupivora, and distinguished, not only by the exceeding brilliancy of the colours of the insects of which it is composed (whence the origin of the name which signifies golden flies), but also by the antennae having thirteen joints in both sexes, the basal joint being the longest, so as to form, at its extremity, an elbow with the remaining joints ; the mandibles are narrow, curved, and pointed ; the lower wings are destitute of nervures, and the abdomen of the females is terminated by an articulated retractile ovipositor, composed of several of the apical segments of the body, the abdomen itself appearing to be composed of only three or four segments. The under surface of this part of the body- is concave ; so then, when the insect is alarmed, it contracts itself into a ball, like a wood louse, leaving the wings only exposed. These insects are adorned with the richest colours, the thorax being generally of a fine blue colour, and the abdomen of a polished coppery flame colour ; they fly, in the hottest sun- shine, about old walls and palings exposed to the sun, with very great agility, seeking entrance into the burrows of other insects, in the nests of which they deposit their own eggs, in the manner of the cuckoo- bees. See CuculhuE. M. St. Fargeau has observed the proceedings of the female of the species Hcdychrum rcgium, which, in general, selects the nests of Mega- chile muraria, a wild mason bee. Having entered one of the nests of this bee, head foremost, it drew back and turned itself round for the purpose of introducing the hind part of its body into the nest, walking back- wards. The bee, however, arrived at this critical juncture with a supply of pollen paste, no sooner, however, did she perceive her enemy than she pounced on it and seized it with her jaws ; like the ChrysuMtE in general, however, it immediately rolled itself into a ball, so that the jaws df the bee, although very power- ful, were not able to affect the least wound upon the polished cuirass of the Hedychrum ; she, however, cut off the four wings of the latter which were undefended, and then let it fall to the ground. She then visited her cell with some inquietude, deposited her store of provision, and retutned to the fields for a further supply. No sooner, however, was she gone than the Hedychrum, which had, during the interval, remained rolled up, unrolled itself, crept up the wall, and quietly deposited its eggs in the cell, from which it had just previously been precipitated, placing them in the midst of the paste against the walls of the cell, which prevented the Megachile from perceiving it. De Geer found the Chrysts vricans, in the resinous ll of the pine, whence he surmised that its larva had been nourished upon the larva which had been previously inclosed therein, having observed at the aottom of the cell of the gall, an empty cocoon, com- posed of loose silk, which the Chrysts had pierced in order to make its escape. This family comprises the genera Parnopes, Chrysis, Stilbum, Euchrceus, Pyria, Hcdychrum, Elawpus, and CHRYSIPHIALA— CHR YSOCHLORIS. Cleples. The genus Ckrysis has the mandibles with one small tooth, the labium rounded and entire, the maxillary palpi much longer than the labial, and the thorax not narrowed in front. There are about thirty-five species of this beautiful family found in this country, two-thirds of which belong to the last mentioned genus, of which the Chrysis iqnita of Linnaeus is the type. CHRYSIPHIALA (Ker). A Peruvian family of bulbous herbs, introduced within the last fifteen years. Linnaean class and order, Hcxandria Mono- gynia ; natural order, AmaryUideas. Generic charac- ter : perianth tubular, tube contracted in the middle, limb erect, and expanded like a funnel in six divi- sions ; corolla shortened interiorly, toothed, and bearing the stamens ; filaments awl-shaped and erect ; anthers incumbent ; style thickly spindle-shaped be- low ; stigma club-shaped ; capsule three-celled, three- valved, and many-seeded. This genus was called Stenomison by Herbert, and Pancratium by Ruiz and Pavon. CHRYSOBALANE^E. The cocoa-plum family. A natural order of dicotyledonous plants, containing nine genera and upwards of thirty known species. By some botanists the order is considered as a section of Rosaceai, to which it is undoubtedly allied. It has also an obvious affinity to Amygdalece, but differs in having irregular petals and stamens, and a style proceeding from the base of the ovary. By the former of these characters, as well as by the cohesion which exists between the ovary and the calyx, the order may be said to approach Leguminoscc, but the position of the styles and ovula, and the relation which the odd lobes of the calyx bear to the axis of inflorescence, are sufficient to distinguish the two . orders. The following are the botanical characters of Chrysobalanccs : calyx five-lobed ; petals more or less irregular, either five or none ; stamens definite or indefinite, irregular in size or position ; ovary soli- tary, free, its stalk cohering on one side to the tube of the calyx ; ovules two, erect ; style single, arising from the base ; stigma simple ; fruit, a drupe one or two-celled ; seeds usually solitary, erect ; embryo with fleshy cotyledons, and no albumen. The plants referred to this order are trees or shrubs, with simple alternate stipulate leaves, and flowers in racemes, panicles, or corymbs. They grow in tropical countries, and are found chiefly in the warm regions of Africa and America. A few species are supposed to exist in Equinoctial Asia, and one is said to be found as far north as the pine-barrens of Georgia, in America. In the latter country, however, it is to be remarked, that the climate is much warmer than in most countries lying in the same parallel of latitude. The order furnishes some esculent fruits, but none of the plants appear to be possessed of any particular medicinal properties. The genera are, Chrysobalanus, Moquilia, Corcepia. Acioa, Parinarium, Grangeria, Licania, Thclyra, and Hirtella. Chrysobalanus Jcaco is an irregular shrub, eight or ten feet high, which grows iu South America and in the West Indies, in situations not far from the sea. It bears small whitish flowers, and yields a fruit the size of a plum, which is sometimes of a white, at other times of a yellow, red, or purple colour, and is eaten in the \Vt-st Indies under the name of cocoa- plum. It has little odour, and a sweetish taste. The 39 root of the plant is astringent, and has been used as such medicinally. Chrysobalanus hdcus resembles the lemon-tree, and is found in the maritime parts of Sierra Leone. It yields an esculent fruit the size of a plum, which is sold in the markets. Parinarium cxcclsum, found on the mountains of Sierra Leone, supplies an insipid fruit, eaten by the negroes under the name of the rough-skinned or grey plum. The kernel of the fruit of P. campestre and montanum is said to be sweet and edible. Grangeria Bourbonia is a tree the size of an oak, with entire leaves and small flowers, found on the Isle of Bourbon. Hirtella Americana. A tree twenty-five feet high found in Cayenne and Guiana, is furnished with a reddish bark, and has its branches covered with fine hair. Some of the species of this genus are tall trees of the tropics, which support themselves on other plants. CHRYSOBALANUS (Linnteus). This is a West Indian fruit tree, called the cocoa-plum. It belongs to the class Icosandria Di Pentagynia, and to the natural order Hosaccte. CHRYSOBERYL. A very beautiful mineral, of a yellowish-green tint, which derives its name from a Greek word, indicative of its peculiar hue. It sometimes exhibits a milk-white opalescence, which appears in general to radiate from the interior of the mineral, and reflects much light. It is seldom found crystallised ; but the primitive form is a prism of 104°. 41'. The most frequent secondary forms are those Fig. I. Chrysoberyl. in the accompanying figures. Fig. 1, is a short and broad six-sided prism, or ihick table; fig. 2, a very short and broad six-sided prism, acuminated on both ends with six planes, set on the lateral planes, and the orifices truncated. This mineral occurs in Brazil, in alluvial soil with the topaz, or in sand-stone with the diamond. Some are also procured from the United States. The beds of the rivers in Ceylon occasionally present this mineral ; it is there sometimes found in conjunction with sapphires, rubies, and tourmalines. The finest specimens of the chrysoberyl employed in this country for the purposes of the jeweller, are those imported from South America. CHRYSOCHLORIS-Golden-green Mole. A genus of carnivorous mammalia, belonging to the division which feed on insects. The generic characters are : two incisive teeth in the upper jaw and four in the under, the cheek teeth stand high, arc separate from each other, arid have the form of triangular prisms. Their muzzle is short and turned up ; their fore feet have only three claws, of which the exterior one is 40 CHRYSOCOLLA— CHRYSOMELID.E. very large, pointed, and crooked, and serves them for digging their way rapidly under ground ; the hind feet have five claws on each, which are of moderate size. Their habits are similar to those of the common mole ; but their organisation is very different. The clavicle is much more slender than in the mole, while the first rib is on the contrary much thicker and very long. The blade bone is also large, arid the humerus is nearly three times the length of that of the mole. The fore arm is also supported by an additional bone. Indeed there is no animal in which the shoulder is better articulated for powerful motion than in this genus, small as are the animals. There is but one species which is well established, the golden mole of Southern Africa (C. Capensis), but this one has occasioned no small trouble to those naturalists who make colour a principal character, and describe animals from museum sepcimens. This species is a very small animal, considerably less than the common mole of Europe ; in consequence of its subterraneous habits it is not very frequently seen ; and in respect of colour it is as perplexing as the cameleon. We believe that the real colour, that is the colour as seen in light which is not refracted, is brown ; but, different from all other mammalia, this small animal has the same metallic reflections in its fur which are observable in the feathers of many birds, the range of these colours being from a deep golden yellow, or rather a sort of bronze red, to a bronze green ; and as all animals which have the metallic reflections lose them when dead and dried, the stuffed skin of this one conveys no idea of what the living animal is like. Hence it has been described as if of different colours and has been attributed to different parts of the world, as to America and Siberia. There are many districts of these parts of the world which are still very imperfectly known, and the habits of those small burrowing mammalia render it very difficult to ascertain what are their numbers ; and therefore the subject is one upon which mistakes are unavoidable, as there may be many species in those unexplored countries of which no individual has been seen. This animal has no apparent tail, no external concha to its ears, and no visible eyes, until they are forced open by direct experiment. Its snout is formed with a movcable citrtilaginous rim, and by means of this and its powerful fore-paws it gets along the ground with considerable celerity. In Southern Africa it is nearly as troublesome in rooting up gardens with its subterranean passages as the common mole is with us. Its time and manner of breeding, and its general habits, farther than that it is a dweller in the earth, are little known ; but it is ascertained that the female has two mammae situated in the groin. This species has sometimes been confounded with those animals which are properly styled rat-moles on account of their having the habits of moles, at least in so far as burrowing is concerned, while they are rodent or gnawing animals in their general structure. Those which have this compound character may be considered as in so far omnivorous, eating indiscrimi- nately small animals and succulent vegetable matter, whereas the cheek teeth of this genus are wholly or chiefly of an insectivorous character ; and therefore it only disfigures those grounds in which it makes its runs, and does not eat the fibres of vegetable roots. Though a small and obscure animal, this is remark- able for its beauty, if it were possible to preserve that beautv iu the dried skin. Its colours have already been mentioned, and we may add that the texture of its fur is more delicately soft, and also more beautiful in its lustre than that of the mole. It is worthy of remark, that these small burrowing animals are neither soiled by mud nor readily wetted bv water. CHRYSOCOLLA. A genus of molluscs esta- blished by De Montfort, but united with the genus Polystome/la, of which it forms one of the divisions. CHRYSOCOMA (Linnaeus). A genus of yellow flowering shrubs from the Cape of Good Hope, and herbs, natives of Europe and North America. These plants are the goldylocks of our gardens, and belong to the natural order Composites, propagated by cuttings and division of the root. CHRYSOLITE. This mineral is characterised by its pistachio green colour. It is brought to Europe from the Levant, and is said to occur in upper Egypt, on the shores of the Red Sea, and in the Isle of Bourbon. The chrysolite has a considerable degree of lustre and transparency ; but it is one of the softest of the precious stones, hence jewels of it be- come dull on the surface, if the slightest attrition be employed. CHRYSOMELID^ (Leach). A very extensive family of coleopterous 'insects, belonging to the sec- tion Tetramera, and sub-section Cyclica of Latreille, which latter group is almost identical with the Lin- naean genus Chrysomela, but which, from the amazing number of additions made thereto since the days of the great Swede, it has been considered necessary to separate into three divisions, namely, the Galerucicke (Galerucitte, Latreille); Ckrysomelidce (Chrysomel'mes, Latreille); and CassuHdee (Cassidarice, Latreille. See CASSIDA). These groups are conjointly characterised by having the body of a small or but moderate size, and of an oval or rounded form, being seldom elon- gated. The antennae are seldom so long as the body, and filiform or gradually thickened towards the tips ; the thorax is sometimes as wide behind as the base of the elytra ; the three basal joints of the tarsi are dilated and spongy beneath, forming a kind of cushion; the legs are of a moderate length, but rather thickened, especially in the part termed the femur or thigh, which in the hind legs is sometimes greatly incrassated, as in the turnip beetles (Halticce) and some others. Generally speaking, these insects are of sluggish habits, frequenting plants and vege- tables, upon the leaves of which they feed both in the perfect and larva state ; being during the latter period of their lives of a soft fleshy consistence, with six legs, and emitting a viscid secretion, which serves to affix them to the objects upon which they are placed. It is here also they are transformed into pupie, the posterior part of the body being affixed to the leaves, &c., and surrounded by the cast skin of the larva. In both these preparatory stages, the body of the insect is ornamented with various colours, and in the perfect state we find nearly the whole group distinguished by their highly polished and metallic tints, whence the origin of their name, which signifies golden beetles. When disturbed, they im- mediately fall to the ground, folding their legs and antennae along the sides of the body. It is, however, in tropical climates, where vegetation reaches its greatest luxuriance, that these herbivorous insects abound; and to so great an extent, that from the state of our collections, we should feel inclined to average the Linnaean chrysomelae at, at least, one- eighth of the whole order of beetles. CHRYSOPHRIS — CHRYSOTOSUS. 41 Lalrcille has arranged the groups of which this division (Cyclica) is composed, from a consideration of the various habits of the larvie, as follows: — 1st, those which cover themselves with their own excre- ments (Cassidce}. 2nd, those which reside in portable cases (Clytkra, &c.). 3rd, naked larva;. 4th, larvae living' in the interior of leaves, feeding upon the parenchyma (Haltica) : but it is to be borne in mind, that this mode of distribution must be cautiously regarded, since the Galerucidcc, to which the Halticce are referable, are naked, and it is by no means de- cided that the larvae of the latter are internal feeders. The three divisions or families above mentioned, may be readily distinguished by the following cha- racters : — 1. Cassidid(E. Antennae arising close together, con- cealed at the base by the thorax. 2. Chrysomclidce. Antennae remote from each other at the base. 8. Galcracidce. Antennae close together at the base, and not concealed by the thorax. The family Chrysomelidu; have the body oval, more or less tending to a globular or an oblong shape ; the antennie are generally slightly thickened towards the tips, and the legs are nearly of an equal size. These beetles, notwithstanding their small or but moderate size, are amongst the most beautiful of coleopterous insects ; they are highly polished, and their colours are greatly variegated, green and gold, bine, purple, and crimson, being very conspicuous in the majority. Some of the species are social, as that found upon the leaves of the willow (C. vitellince}, the larvae of which feed in regular rows along the leaves. These larvae have the body thick and fleshy, and terminated by a fleshy tubercle, which is employed as an addi- tional seventh leg. The larvae of one of the largest British, species (C. populi}, emits a disagreeable scent, a yellow oily fluid being discharged from the limbs when the insect is disturbed. Some of the larvae undergo their transformations under ground. The pupaj, which does not present any peculiar cha- racters, is of an oval form, and affixed by its posterior extremity to the leaves, the perfect insect making its appearance at the end of several weeks, or occasion- ally in a few days. The family comprises two very distinct sections. 1st. Those having the head but slightly deflexed and exposed to view, the antennae seldom exceeding half the length of the body, and slightly thickened to the tips, with the body of an oval form. Here belon^ the genera Phaedon, Melasoma, Ckrysomcla, Helodes, and Timarcha, all of which are British ; and Coltupit, Podontia, Phyllocharis, Doryphora, Paropsis, Trocha- lonota, Cyrtonus, which are exotic. The genus Chrysomda, as restricted in the latest works, is distinguished by having the palpi somewhat hatchet-shaped, the thorax transverse, the elytra se- parated, and the body furnished with wings. The tibia> also have a tooth or tubercle on the outside near the extremity, fringed with hairs. There are nearly thirty British species of this elegant genus, ol which the Clirysomela sanguinolenta of Linnaeus is one of the most common examples; it is about one-third of an inch long, of a blue-black colour, with the elytra widely margined with red. The second section of this family comprises those species which have the head vertically immersed into the frontal cavityof the thorax, so that the body form a kind of thickened cylinder, having the anterior part cut oil' perpendicularly. The antennae in the majority an; almost as long as the body, and slender to the tips. Here belong the genera Cryptoccpkulus, Eumolpus, Colaspis, and Clythra, all of which are British, toge- ther with Cklamys, Lamprosoma and Euryopc, exotic jenera. The second genus comprises the Emffotput itis, Fabricius, a species which has become distin- guished by its ravages upon the vines in the wine countries of Europe ; its larva appearing in the spring, and devouring the leaves of this plant, as well as the young buds, as soon as they appear on the stems ; it also gnaws the footstalk of the bunch of grapes as soon as it is exposed, causing it to droop and die ; sometimes however the shoot is sufficiently strong to survive the injury, but the grapes in these bunches are of small size on that part which cor- responds with the injury, in consequence of. their receiving but a small portion of sap. The perl'ect insect is of a black colour, and pubescent, with the elytra, the base of the antennae and tibiae, of a reddish- brown. The genus Clythra has the antenna; very short and serrated ; the larva; reside in tubular ense.^ of a leather-like texture, which they bear about with them. There are several British species. CHRYSOPHRIS. A genus of spinous-finned fishes, belonging to the gilt-head family SPAROID^E, under which some notice of the genera composing that family will be found. CHRYSOPHYLLUM (Linnzeus). West Indian fruit trees of large size, yielding useful fruit called the star apple. Linnaean class and order Pcntandria Monogynia ; natural order Sapotca:. Generic charac- ter : calyx five parted ; corolla bell-shaped and rotate ; limb divided into five spreading petals ; stamens inserted in the tube of the corolla ; stigma almost sitting, peltate, and of ten lobes ; fruit, a round apple of from five to ten cells, each containing one seed covered with a bony shell. The foliage of these trees is beautiful, for which they have a place in our hot-houses ; but they never arrive at that amplitude to produce their fruit. They are increased by cuttings like other stove plants. CHRYSOSPLENIUM (Linnjeus). A genus of three species of plants, two of them British, and frequently found on wet boggy ground, and known by the trivial name of golden saxifrage. They belong to the tenth class of Linnaeus, and to the natural order Saxifragcce. CHRYSOTOSUS. A genus of spinous fishes, belonging to the mackarel family, of which the characters are : a total absence of teeth, a single dorsal fin furnished with spines, the body compressed, the scales remarkably small, and the eyes placed late- rally, with the exception of the coryphenes to which they are nearly allied, this genus is one of the most beautiful that inhabits the ocean. There is one spe- cies which is occasionally met with in our seas, though it is a ranging fish, and therefore is but rarely caught. When a specimen is met with, its beauty draws a considerable degree of attention, and therefore it has had many names bestowed upon it. It is the ophah of Pennant, the Zeus imperialis of Shaw, and the moon- fish of other writers. It is a fish of considerable size, and so much compressed, that when seen laterally its figure is nearly round. Its caudal fin is white, and very much forked ; its dorsal fin is very elevated and sithe-shaped ; its ventral fins are very long ; and all the fins excepting the caudal are bright red. The ground colour of the bodv is a beautiful violet, 42 CHTHAMALUS — CICADA. marked with white spots; but the colours vary a good .deal with the light in which the fish is seen. The b.tck, as turned away from the light, appears a beau- tiful blue with silvery spots, while the rest of the body reflects an endless variety of brilliant colours. Its habits, further than that it is a very discursive fish, are very little known, and we believe not more than a single specimen has been met with at one time. CHTHAMALUS (Ranzani). The shells of this genus are extremely flat; the coronary part with its sides much thicker at their base and formed of six pieces, as in the Balani, areas nearly equal ; the internal division short, a membranous stem or support ; the opening tetragonal, with nearly equal sides, surrounded by a membrane to which is attached horizontally, an operculum, composed of four pieces, slightly pyramidal. Only two species are known of this shell ; they inhabit the Mediterranean sea, and are classed in the family Balaiudea. They appear an intermediate genus between the Balanidcs with pyra- midal opercula, and those with horizontal opercula. CIBICIDES(De Blainville). A species of shell of which only one species has yet been described. The C. refulgent, nevertheless, is so strongly charac- terised, that it merits the rank of being considered a genus. Shell trocho'ide, very much flattened, and umbilicated with the chambers visible and radiating from the centre on one side, conical but not spiral on the other ; the aperture linear, through the height of that side. 1st class Cephalophora ; 3rd order Poly- ikalaniacea ; 6th family Turbinacea. CICADA (Linnaeus; Cicadariae, Latreille). A group of insects, which, in the 1, inna.au system, formed the genus Cicada, but which, from the great increase in the number of the species, and the great variations in structure which they exhibit, has been formed, by modern entomologists, into several distinct families, each consisting of numerous genera. They are characterised as a division of the order Hemiptera, and sub-order Homopterita (Kirby), by the minute size of the antennae, which are of a conical form and terminated generally by a fine bristle, and these organs have never more than six or seven joints ; the tarsi have only three joints ; the wings are concealed by a pair of hemelytra or wing covers which, however, during flight, perform the offices of wings, being of a similar consistence throughout their whole extent, in which respect they differ from the Cimicidtz or bug tribes, in which the wing-covers are composed of two distinct kinds of membrane, or rather of corium and membrane ; the proboscis, which is employed in wounding and sucking the juices of plants, arises from the under side of the head, near the fore legs ; the hind legs are adapted for leaping ; and the females are furnished with an apparatus well fitted for depo- siting their eggs, being composed of two saw-like organs, somewhat similar to those of the true saw- flies, Tentkredinidte. These insects, which from their saltatorial powers have acquired the name of tree-hoppers, are amongst the most celebrated of the lower animals. They were known to the Greeks, who were accustomed to keep them in cages for the sake of their song, under the name of Tetrix, and they form a favourite theme in the verses of every Grecian bard from Homer to Anacreon. " Sweet prophet of the summer," says the latter, addressing one of these insects, "the muses love thee, Phoebus loves thee, and has given thee a shrill song, old age does not wear thee out, thou art wise, earth-born, musical, impassive, without blood, thou art almost like a god!" The hiero- glyphics of Egypt, in like manner, give evidence of the attention with which these insects hud been observed ; and in which, from their organs of sound, which were supposed to be placed upon the back and not at the moutli, they were emblematically represented as the ministers of religion. Aristotle, who named these insects Tetrix, says that that they have no mouth, but a kind of tongue placed beneath the breast, and serving to suck up the dew. He likewise distin- guishes two kinds of tetrix, the larger which sing, which he calls " achetes," and the smaller, which arc silent " tettigonion or tettigonia ;" cicadrasta; in Latin. The eyes were supposed to be very weak, for Pliny adds, that if the finger be placed close to them, they will creep upon it as though it were a leaf; this however is certainly incorrect, for it is well known that when they are approached, they use both their wings in flying and legs in leaping, in order to get out of harm's way. The female, says Pliny, is pro- vided with a pointed instrument or auger, which pierces the earth, reeds, stems of the vine, &c., when the insect wishes to deposit her eggs. The pupae of these insects have very little the appearance of the perfect flies ; the body is thick and heavy, and the fore legs very large, with the anterior thighs greatly incrassated and toothed. They were called by the Greeks Tetligometrte, or the mother of the cicadas. Diodorus informs us that these insects do not exist in the district of Locres, because Hercules, annoyed by their chirping, prayed the gods to deliver the country from their noise, whereupon his prayers were heard. Several Eastern nations eat these in- sects ; the males before coupling, and the females after impregnation, are most relished. Isidore of Seville, doubtless misled by the frothy matter in which the larva of the Cicada (aphroplwm] spumaria is found, says that the Cigales or cicadse spring from the saliva of the cuckoo. " Cuculorum nascuntur sputo," Orig. lib. xxii. cap. 8. The organs by which the chirping of the cicadae is produced, have been well described by Reaumur. They are placed on the under side of the body, between the base of the hind legs and the abdomen, and consist externally of a pair of large flattened plates of a horny texture, varying in form in the different species. When raised, they are found to conceal a large cavity par- tially covered with membrane of a much more delicate nature than the external covering, with a horny plate in the middle, placed horizontally along the bottom ; the sound is, however, produced by a bundle of mus- cles still more internally, and when these strings are pulled and suddenly let go, even in a dead specimen, the sound is produced as well as though the insect were still alive , the sound issuing through an opening contrived on purpose, somewhat analogous to the sound hole of a violin. It is to be observed however, that it is only the male insects which are provided with this apparatus, the opposite sex being destitute thereof, and consequently silent ; hence the couplet of the Rhodian bard, Xenarchus, not over-famed for his gallantry to the fair sex, Happy the cicada lives Since they all have voiceless wives. Great diversity of opinion has been entertained of the music of the tetrix or cicada ; this however may CICHORACEjE — CICINDELID^E. perhaps be accounted for, from the circumstance of several distinct species having been comprehended under the same name, varying in their powers of song: thus a cicada sitting upon a harp was the usual emblem of music, which appears to have had its rise from the following legend. Two rival musi- cians contending upon the harp, a cicada settled upon the instrument of one of the artists, and supplied the place of a broken string, and so secured him the victory ; and in Surinam these insects are also called harpers or lyre-men. By others, however, they have been held in less estimation ; thus Virgil tells us that they burst the very shrubs with their noise. Some of our translators have indeed adopted the very com- mon error, that they were insects of a very different family. Thus Dryden (Georgic iii. p. 510) sings — When creaking grasshoppers on shrubs complain, although from Virgil's words Et cantu querelac rumpent arbusta Cicada, Georgic iii. p. 328, it is evident that the insects now under consideration were alluded to. In like manner Dr. Shaw tells us, that the " cicada is perpetually dunning our ears with its most excessively shrill and ungrateful noise." The curious apparatus with which the females are provided, for enabling them to make slits in the branches of trees for the purpose of depositing their eggs therein, has somewhat the appearance of two long narrow files, pointed at the end, moving with a separate or alternate motion, and supported by a broader back entire piece. This apparatus in the larger species is about half an inch long, and is ordi- narily concealed within the terminal rings of the abdomen on its lower surface. The situations upon the twigs on which the eggs are placed, are easily recognised by the little inequalities upon the surface, placed one after the other. Each hole contains from five to eight eggs. The preceding observations have reference to that portion of the Linnaean genus which were termed Mannifera, and comprises the modern family CicadicUe. The divisions established at the expense of the for- mer group (together with that of the Linnsean Fulgorce, which are so intimately allied to the former, that some of the Linnsean cicadae are now placed in the family of which Fulgora is the type) are as fol- lows: 1st, the Cicadidee, having the antennae six or seven-jointed, and the ocelli three in number. This family corresponds with the genus Tettigonia of Fabricius, and comprises only a single genus, for which the Linnsean name cicada has been retained. Latreille, in several of his recent works, proposed several other generic divisions, but they have not been adopted. We possess in England only one species belonging to this family, which has been supposed to be the C. hcematodes, but which Mr. Curtis has figured under the name of C. Anglica. It is met with in the New Forest. 2nd, the Fulgoridee, having the antenna; three-jointed, and inserted close beneath the eyes, with a long terminal bristle ; TWO ocelli ; legs formed for leaping ; no musical drums ; the head is often produced in front into a nose. See FULGORID^:. 3rd, the CermpidtB, having the an- tennae of similar form as in the second family, but inserted between the eyes and the head, which is not rostrated. See CERCOPIDJE. CICHORACE.E. See COMPOSITE. CICHORIUM (Linnaeus), is the succory of 43 English authors ; a common plant, found by the sides of fields and highways, and is sometimes cultivated for sheep food. It has large bright blue flowers, — • belongs to the class Syngenesia ol Lintneus, and to the natural order Composites. There are several annual species, one of which, a native of India, is the well known salad plant called Endive (for the cultiva- tion of which see ENDIVE), long cultivated in gardens everywhere. In some places on the continent of Europe, the roots of the succory C. intybus, are, when full grown, taken up, cut in small pieces, dried in an oven, and afterwards ground and used instead of coffee. CICINDELID.E (Leach). A family of coleo- pterous insects, belonging to the section Pentamera and tribe Adcphaga (Gcodcphaga, see CAIIABIDA:) being placed by modern authors at the head of the Coleoptej-a, from the circumstance of the external lobe of the maxillae being converted into an additional pair of feelers, forming the internal maxillary palpi. The jaws are very powerful and horny, with several strong teeth ; the maxillae are terminated by a move- able spur ; the lower lip is hidden by the chin, and the eyes are very large and prominent ; the legs long and slender, and the wings generally developed. This family comprises nearly twenty genera, one only of which is found in England, namely, Cicindela, the remainder being in fact extra European, and consequently very little being known respecting their habits. Of these insects, which, from their ferocious habits, as well as from the spots and markings with which they are ornamented, have obtained the name of tiger beetles, there are only six or seven British species, although the genus comprises more than one hundred and twenty. Of these British species the most common is the C. campestris, an elegant insect, having the body of a fine green colour, with several white spots on the wing covers. Nothing can exceed the metallic brilliancy exhibited by these insects, when on the wing in the hot sunshine. They appear early in the spring (we have seen them flying this morning, April 8th, in the Horticultural Gardens) ; on approaching them they immediately take wing, exposing the upper surface of the abdomen, which is highly polished, and ornamented with the most beau- tiful colours. Their flight is however but of short duration ; they, however, rise again immediately as you again approach them. The great rapidity of their motions, renders escape impossible to any luck- less insect which they may attack. We have noticed that this insect emits a fine rose-like scent. Some of the species seern to make but little use of their wings, as in the British species, C. Gcrmanica. The female of the C. campeslris is distinguished by a small black spot on each elytron, not far from the base, and near to the sutural line. The most complete account hitherto published relative to the transformations of these insects, is contained in the Annales des Sciences Naturelles. The larva? reside in cylindric burrows of great depth, which they excavate in sandy situations, at the mouth of which they generally station themselves, the head of the larva occupying the mouth of the burrow. They are about an inch long, rather depressed and narrow, composed of twelve rings exclusive of the head, and the anal segment. The head is furnished, like the perfect insect, with a pair of very powerful hooked jaws ; the legs are six in number, and com- paratively strong. The reader will smile with us at C I C 0 N I A. the following account given of one of these larvae described by Dr. Kidd " with an eye to science." " Oh such a beauty ! the Parcae, sweet creatures, the Eumenides, gentle turtle doves, were lovely in comparison. Aspect vicious ; temper ferocious ; eye infernal ; jaws diabolical, stuck on the wrong way like a h'gure-head shipped looking aft; head big; back humped ; the hump adorned with two hooks." — Rustictis, in Ent. Mag. The description given ol the jaws is correct, and affords a curious instance ol adaptation of means to an end, of which insects exhibit such numberless examples. One cannot at first but wonder what can be the cause of these jaws being so singularly stuck on the head, being in fact turned upwards, instead of downwards as is the ordinary custom in insects ; but when we consider the habits of the insect in conjunction with the peculiarities of its structure, our wonder ceases ; the insect takes its station at the mouth of a cylindrical burrow, in the hope of seizing upon the stray beetles and flies; now if the jaws were in the ordinary position, the insect would be compelled to throw back its head to a dis- tance beyond its powers, were it to attempt to snap at its prey when creeping over or near the mouth of the burrow ; but as the jaws are placed, it is enabled to effect this without the least difficulty. The two hooks upon the back of the eighth segment of the body are also especially worthy of notice, as it is by their assistance that the insect climbs up and retains its situation at the mouth of its cell. The amusing author above quoted turned up one of these larvae, in order to watch its proceedings. " When first un- earthed he was monstrous sulky, and lay twisted in a kind of half kink, for all the world like a pot-hook ; but he soon found the inconvenience of this, and set to work to make another hole, for which he used his feet and jaws, loosening the sand with his feet, and fetching it out with his jaws," (he might have added that the back of the head being rather concave, is employed as a basket for carrying up the loosened particles) ; " in this way he got down about half an inch, and then adroitly hanging himself to the edge of the hole by the hook (hooks) in his back, he con- tinued his labours in this droll position ; at last he got quite out of sight, and as he did not come up again, I concluded he was taking a nap after his labour, and so I would not again disturb him." The perfect insects are very common in most sandy districts. They abound in the neighbourhood of London, and the circular orifices of their burrows may be seen in all directions, on the sunny sides of gravel pits, &c. CICONI A — STORK. A genus of birds belonging to the Cultrirostral division of Cuvier's order of Echas&iers, which answers nearly to the Grallce of other naturalists; for the relations see the article BlRD. The storks are a very interesting race, whether we regard their size or their habits; and in those coun- tries where the rains are periodical, much of the country laid under water for a time, and numerous animals remain left by the subsiding waters, which would taint the air if they remained and were decom- posed there, they perform a very important office in the general economy of nature. They are all more or less migratory, and, with the exception of the colder latitudes, are found on the low grounds in almost every part of the world, though the true storks are mostlv confined to the eastern emit incut. The characters are : bill long, straight, stout, even, cylindrical, in the form of a lengthened cone, acute, cutting ridge, rounded, of equal height with the head ; the under mandible slightly bent up; nostrils longi- tudinally clel't in the horny substance, and placed in a groove ; eyes surrounded with a naked space which does not communicate with the beak ; legs long, and furnished with four toes, of which the three anterior are connected at the base by a membrane, and the hind has its first joint resting on the ground ; wings of moderate size. Storks live in marshy situations, and feed principally on reptiles, frogs and their spawn, as well as on fish, small mammiferous animals, and birds. In many countries they are a privileged race, being cherished and protected, on account of the noxious animals which they destroy. They mou'.t in autumn, migrate in large bodies, and are easily tamed. The youny of the first year do not very materially differ in appear- ance from the full grown birds ; but they may still be recognised, on their return in spring, by the dull black and white of their plumage. The sexes are not dissimilar in appearance. Storks have no voice, properly so called, though when they are irritated, or otherwise strongly excited, they contrive to make a clanking noise, by beating the edges of their mandibles, which are very hard and strong, against each other; when they do this they place the head in rather a singular position ; they recurve it backwards, until it is nearly parallel with the back, and leaning on it. In this position the upper mandible is undermost, and held firm by the posture of the neck, while the under, which is now uppermost, beats much more easily and forcibly against the other than if the bill were in its natural position, as in this case the weight of the mandible aids the stroke, while it acts against it in the other. It does not appear that the muscles which move the under mandible, strong as they are, would be capable of performing this singular sort of cymbal playing, if the weight of the organ were not brought to their assistance ; for as the bird brings its head back to the natural position, the sound gets lower, and when it snaps with the bill in the natural way, no sound is produced. Storks are birds of long flight and powerful wing, and they rise high and proceed gracefully upon their long aerial journeys ; on the ground their march is rather slow but stately, their steps being long and measured. As is the case with most birds of the order, they carry the foot forward simultaneously with the leg, and this sort of locomotion is owing to a peculiar system of articulation. To the same mecha- nism the storks are indebted for the faculty of sleeping upon one leg, holding the other bent, and often even suspended rectangularly. The pleasant story told by Boccaccio, of the gentleman and his cook, affords an agreeable illustration of this habit of the stork : a roasted stork had been ordered for dinner, and the egs of this bird being the most substantial as well as he most juicy parts of it, the master was of course anxious to have them for his own use. But there was another claimant : the cook had a sweetheart, and she was so urgent for a leg of this stork that the gal- ant cook was constrained to cut it off and give it ier; when the mutilated stork made its appearance on the table, the master, in a great rage, sent for the uok, and charged him with having purloined the leg. Storks have but one leg, sir,"said the cook with the ut- C I C O N I A. 45 most composure ; " and if you will condescend to repair with me to the bank of the river to-morrow morning, I will convince you of the fact." Morning came, the river was visted, and sure enough there was a number of storks, all of which appeared to have but one leg. " There they are, sir," said the cook, " and you see there are no more legs than storks." " Hoo ! " said the muster, upon which every stork displayed his other leg. " Now," said the master, " have not I convinced you what a cheat you are ?" "I beg your pardon, sir," said the cook, " not one of these storks put down his other leg till you cried ' hoo,' and of course if you had cried ' hoo' to the stork yesterday, he would have put down his other leg too." We shall now give some account of some of the principal species. WHITE STORK (Ciconia alba). White, with the orbits naked and crimson ; quills and upper tail- coverts dusky green. The irides are brown ; and the feathers on the breast long and pendulous. Length about three feet and a half; extent of wing upwards of six feet ; size about that of a turkey. The young have the black of the wings tinged with brown, and the bill of a dusky red. A pure white variety, called Sterchi by the Bulgarians, is found in the valley of the lower Danube. From the familiarity of their disposition, and its other moral habits, the stork is one of the most popular of littoral birds, and has been generally regarded as the friend of man, attached to his dwellings, nestling on roofs and chimneys, catering on the banks of the most frequented rivers, in cultivated fields, and almost in gardens, not even shrinking from the bustle of crowded cities, taking up its abode in towers, and everywhere respected and welcomed. In Holland it is protected, because it checks the multiplication of reptiles in the marshes and humid flats ; the Vau- dois cherish and venerate it for its friendly offices; the Arabs, in like manner, treat it with the most hos- pitable regard ; and the Turks and eastern tribes consider it as a sacred bird, which they are forbidden to kill. At Constantinople, accordingly, the storks build their nests in the streets ; but in other countries they generally prefer a lofty situation. A mussulman cannot patiently bear to see one of them molested; and the ancient Thessalians made the killing of them a capital crime. The Moors, too, religiously abstain from offering violence to them ; and hence the valley of Monkazem appears to be the resort of all the storks of Barbary, which, in this district, are more numerous than the inhabitants. The white stork is of gentle manners, easily tamed, and manifests a sense of cleanliness. Although it has a pensive and even melancholy air, it occasionally indulges in gaiety and pastime, associating even with children, and partaking of their amusements. " I saw in a garden," says Dr. Hermann, " iu which the chil- dren were playing at hide and seek, a tame stork join the party, run its turn when touched, and distinguish the child who was to pursue the rest so well as, along with the others, to be on its guard." Among the engaging attributes of these birds have been justly reckoned gratitude, conjugal fidelity, and filial anc parental affection. They seem in fact to be very sensible of kind treatment saluting, with a noisy flap ping of their wings, the houses whose inmates hac given them a friendly reception during the preceding season, and repeating the same ceremony on taking leave. With wonderful constancy the same pai eturn to the same haunts, and join in mutual and ond caresses after their long voyage. The tender affection which the stork manifests towards her young, las been proverbial even from remote antiquity. She eeds them for a considerable period, nor quits them ill they are strong enough to defend themselves, and o provide for their own subsistence. When they )egin to flutter about the nest, she bears them on icr wings, and protects them from danger ; and she las been known rather to perish along with them han abandon them to their fate, an affecting instance of which was exhibited in the town of Delft, in 1636, vhen a fire broke out iu a house that had a stork's lest on it, containing young that were then unable to ly. The old stork, returning with some meat for hem, and seeing the danger in which they were exposed, the fire having almost reached the nest, nade several attempts to save them, but, finding all n vain, she at last spread her wings over them, and n that endearing attitude expired with them in the lames. Young storks have also often been observed to lavish the most affectionate and assiduous cares on their aged and infirm parents ; and the ancient Greeks, observant of this striking instinct, enacted a aw to compel children to support the authors of their xistence, and the guardians of their infant years. The stork is capable of sustaining a lofty flight, and of performing long journeys even in tempestuous weather. When on wing it pushes its head straight forward, with the feet extended backward. It returns to Alsace about the end of February, to Switzerland in the course of March, and to Germany early in May, but it rarely visits this country. If a pair on their return find their former nest deranged or demo- lished, they repair it with sticks, rushes, and other plants that grow in moist situations. It is usually placed on high roofs, the battlements of towers, and sometimes on the tops of tall trees, on the brinks of streams, or on the projection of a precipitous rock. In France it was formerly customary to lay wheels on the roofs of houses to induce them to build on them, a practice which still exists in some places. In Holland boxes are placed on the roofs of houses for the same purpose. The hatch consists of two, three, or four eggs of a yellowish sordid white, larger than those of the goose, but not so thick. The male sits on them while the female is abroad for food. The young make their appearance in the course of a month, when the parents diligently search for and carry to them the proper aliment, which they disgorge from their gullet or stomach. Both parents never leave the young at the same time, but while the one is ranging in quest of food, the other keeps watch, standing on one leg in the manner above described, and with its eye steadily fixed on its charge. When the young first break the shell, they are covered with brownish dosvn ; and their legs are so weak that they are not able to move in the nest in any other way than by shuffling about upon their knees. Wrhen their wings begin to acquire strength, their mothers accompany them in easy flights, though it is rather too much to assert, as is sometimes done, that they literally tench them to fly. There is no teaching, in the ordinary sense of the word, among animals of any kind, either in motion or in voice. The supposed teaching in walking or flight is merely the old ones keeping company instinctively with the young ; and the teaching of music is simply rivalry in that impulse which occasions the song. 46 C I M B E X. In some places storks nestle very thickly together, but they always live in the greatest harmony. At Bagdad there are hundreds of nests, on the houses, the walls, and the trees ; and among the ruins of Persepolis, there is a stork's nest on the top of every nodding fragment and mouldering column. About the month of August they begin to move from their more northerly haunts ; and they move sooner in moist and cold seasons than in dry and warm ones. Previous to their departure they assemble in very numerous flocks upon some plain, and hold a conversation in that peculiar clanking of their bills of which we have taken notice. The motion of the mandible while this is performing is very rapid, and the clattering which they make is considerable. Sometimes they meet, break up, and meet again, before they take their final departure. When they do move off, it is done in perfect silence, and often during the night ; and they also arrive in silence, so that neither the beginning nor the end of their jour- neys is often noticed. They rise rapidly to a great height, and as they utter no sound when on the wing, they are seldom observed when passing over the plains. But on the mountains they are more easily seen ; and the flocks of them which are observed from such points of view are often very numerous. Shaw, the traveller, mentions having seen flights of them passing over Mount Carmel in their flight northward from Egypt, a mile in breadth, and taking three hours before they all passed over the point of observation. In Asia and the east of Europe they are very numerous, ranging into Siberia, into Russia, and even into Sweden ; and they do not seem to be much affected by the cold. Those which breed in the north, in the early part of the season, generally have another brood in Egypt and the other southern countries ; but they do not all quit these southern latitudes ; and some of them are stationary in the east of Asia, and in some of the Asiatic islands, as well as in the north of Africa. In all their characters and habits they are very interesting birds ; they may be said to be almost tame in a state of nature ; and they live in confinement without any apparent incon- venience, or even much reluctance ; but confinement 3s obviously contrary to their habits, as they do not breed in that state, and whenever animals cease to obey this, the strongest impulse of nature, we may safely conclude that the state is not one for which nature designed them. It is also worthy of remark, that, generally speaking, these animals, which will jiot breed in confinement, and therefore cannot pro- perly be domesticated, are never of so much use to man as those which breed freely. Notwithstanding the tale of Boccaccio, the stork is very far from being a bonny Jiawke, even to the most perverted epicure ; for its flesh is not very nutritious, and it is at the same time far from being savoury ; therefore, there is but little temptation for taking the bird out of that state of nature in which it has so many interesting points. THE BLACK STORK (Ciconia nigra). The black stork measures about three feet in length. The upper part is blackish, with metallic reflections ; and the lower part of the breast and the belly white. The naked space round the eyes, and that on the neck, and also the bill, are crimson : and the feet are deep red. The colours of the young are different, the upper part being blackish-brown, with reflections ; the feathers on the head and neck brown, with red- dish borders ; and the naked skin round the eyes and on the neck, and also the feet, are olive green. In consequence of this difference of colour, the young birds have sometimes been described as a different species, under the name of the brown stork. Though these two birds agree in their general characters, the habits of the black one are, in many respects, the reverse of the white. Like that it is a ranging and migrant kind ; but, instead of resorting to towns and inhabited places, it seeks those which are lonely and sequestered. Its haunts are the remote and inaccessible marshes, and the borders of lakes which are seldom visited. It is found in considera- ble numbers in the more sequestered parts of the Alps, always on the borders of the waters, where it subsists, at least in part, by fishing. It hovers over the surface, and occasionally plunges down to snatch its prey. It occurs in Poland and Prussia, and par- tially in Germany, also in some parts of France ; but it is very rare in Holland where the white species is very plentiful. Indeed it seems to shun not only the peculiar haunts, but the countries which are most frequented by its congener. In Britain it has occurred .only as a very rare straggler. It builds in trees, in the depth of the forests ; and, as is the case with several others of the larger birds of this division of the order, it appears to prefer fruit to any other trees, no doubt because it can stand on the horizontal branches which these send out, much better than on the sprays of deciduous trees. The eggs are from two to four, of a dull greenish white, with some blotches of brown, which do not appear to be constant. Though these birds sometimes fish, fishing is not their peculiar, or even their principal, resource. They feed upon reptiles, mollusca, insects, the smaller ground mammalia, and also upon any animal remains or offal which they can procure. They are voracious birds and appear to migrate after their food rather than in consequence of any other instinct. On their long journeys they are birds of very lofty flight ascending upwards till, notwith- standing their large size, they are barely, if at all, visible. They may be partially tamed ; but there is little inducement to tame them, as they have not the interesting manners of the white storks, and their flesh is even less palatable. THE AMERICAN STORK (Ciconia magnari) is de- scribed as differing from the white stork of the eastern continent chiefly in having the bill of an ash colour. It is white, with the wings and upper tail-coverts black ; the irides white, and the feet red. It is about three feet in length. Its principal locality is said to be to the eastward of La Plata in the uninhabited part of the pampas. Some of the accounts state that it breeds in confinement, but this is contrary to the general habit of the genus. A few more species and varieties have been men- tioned, such as the small black stork of Northern Africa, and the purple stork of India ; but the ac- counts of them are a little confused. Some notice of the great stork of India, which is an allied species, will be found under the article ADJUTANT ; and the Jaribus will be noticed in the article MYCTERIA. CIMBEX (Olivier : Crabo, Geoff.> A genus of hymenopterous insects belonging to the section Securifera, and family Tenthredinidce, and forming together with the several sub-genera which have been separated from it by Dr. Leach, (Zareza, triJtiosoma, Abia, clavettaria\ a section in that family distinguished C I M E X- C I N C H O N A C E .E. 47 by having the antennae short and knobbed at the tip, and composed of only four, five, or six joints ; the wings are large, with the costal and sub-costal nerves of the upper pair soldered together ; the spurs of the tibia; are blunt, and the joints of the tarsi are provided beneath with spongy cushions. These insects are amongst the largest species of the saw-Hies, whose curious economy in the formation of the eells for the reception of their eggs and the apparatus with which they are furnished for forming these cells will be sub- sequently related. They are produced from large fleshy larvae which greatly resemble the caterpillars of lepidoptera, whence they have been termed by the French entomologists "fausses chenilles," but they are provided with a greater number of legs, the true cater- pillars not having more than sixteen, whilst the larvae of cimbex have twenty-two, the eleventh segment of the body being alone destitute of these organs. It is acurious circumstance that larva1 so closely resembling eaeh other, as those of cimbex and some of the moths belonging to the family Noctnidcc, should produce insects so totally different. In their former state they both feed upon the leaves of the same tree, and their whole appearance is so similar that it would be impos- sible for a person unused to entomological pursuits to conceive which of the two would produce the moth, whilst in their perfect state no two insects would be found more unlike, in characters, habits, appearance and structure. The transformation of two of the largest species, Chnbcx lutca and ni/lvanim. have been observed by Lyonnet, whose excellent figures, pub- lished in his posthumous researches, represent the entire structure of the insects in great detail. The larva- of the former, having obtained their full growth, descend into the earth in the month of July, where they form cocoons of a very firm consistence, in which they undergo their change to the pupa state, the rlies making their appearance shortly afterwards. CIMEX (Linnaeus). A group of insects of very considerable extent, forming in the Linnaean system a single genus under this name, belonging to the order Hcmiptera. In the modern system of entomo- logy, this group has been divided into numerous distinct families, each comprising various genera and sub-genera, and the whole has been raised, under the name of Geocorisa, or land bugs, to the rank of one of the three divisions of the heteropterous portion of the order Hcmiptera, the two other divisions havin for their types the genera Ncpa and Notonecta of Linnaeus. As a group, therefore, the Gcocorisa, of Linnsean cimex, is distinguished by the antennas being exposed, longer than the head, composed of four or five joints and inserted between the eyes, near to their inner margins. The tarsi are three- jointed, the basal joint being often very small, the body is of an oval or oblong form, the legs are formed for running, the wings are membrana- ceous, not longitudinally folded, and covered, when at rest, by a pair of wing-covers, of which the basal portion is of a leather-like consistence and opaque, whilst the extremity is membranaceous and more transparent, the thorax or rather the prothoracic segment is of a large size and performs the office of a thoracic shield as in the coleoptera, whereas in the homopterous division of the order it is small ; the wings and wing-covers when at rest are horizontal or at least bv.t slightly inclined — sometimes, as in the bed-bug, they are entirely wanting. The mouth con- sists of an elongated and articulated proboscis, includ- ing several fine setae which are employed in wound- ing vegetable or other substances upon which these insects feed. Latreille has divided this group into various families, or rather sub-families, to which the following names have been applied : 1st. The Pentntomidcc, having the antennae five- jointed, the rostrum four-jointed, the labrum or upper lip long and transversely striated. 2nd. The Core/dee, having the antennae four-jointed, the rostrum four-jointed, the second joint longer than the third, the ocelli at the same distance from each other as from the eyes. 3rd. The Lygceidce, differing from the latter in having the second joint of the rostrum shorter than the third, with the ocelli placed near the eyes. The species are of small size and obscure colours, and are generally found in the ground. 4th. The Capridee, being destitute of ocelli, and having the terminal joint of the antennas very slender and the rostrum four-jointed. 5th. The Cimicidae (Membranacece, Latreille), having the rostrum very short, and only two or three jointed, the labrum short and not striated. 6th. The Reduviidcc, having- the rostrum very short, but exposed, curved, and of considerable strength, and the head is narrowed behind into a neck. 7th. The Acantkiid more agreeable ornament than an orange tree, while in flower, placed in the entrance hall of a mansion. The shaddock, or pommelmoc, as it is called by the Portuguese, is the largest, both as to size of tree and fruit, of any of the tribe. In India, when seen loaded with fruit nearly ripe, it is certainly a magnificent object : the deep green glossy foliage, forming a dense background to the large bright yellow fruit scattered over the exterior of the branches. A full-sized fruit is not less than five inches in diameter ; and, though less juicy and more acid than the orange, it is much sweeter and less acid than either the lemon or the lime. The shaddock is a dessert fruit ; and so loosely are the vesicles composing the pulp attached to each other, that they are separated by the fingers, and may be eaten singly like grapes. Their qualities are con- sidered anti-scorbutic ; and homeward-bound Eu- ropean ships usually lay in a store of them with which to proceed on the voyage ; they, however, require to be suspended singly in net bags, as they do not keep long if laid together in a locker. The lime in its wild state is, when young, a very prickly, rigid look- in •_' ^hrnb; but becomes almost or wholly spineless when old, or when domesticated. Its juice, however, is, perhaps, superior to all others for medical and culinary purposes. The Chinese, who may be called a nation of gar- deners, possess many varieties of the citrus, and especially some excellent oranges. Their mandarin variety is a very superior fruit, and has the singular property of discharging the rind from the-pulp when fully ripe. These oranges are very plentiful, and may be purchased very cheap in the streets of Can- ton in the season (spring), provided the seller be allowed to strip the fruit and retain the rinds, of which they make some specific use. There are also several varieties, differing in the size and flavour of fruit, manner of growth, size of leaves, &c., many of which are already in European collections. CIVET — Viverra. A genus of carnivorous mam- malia, placed by Cuvier last in that division of digitigrade carnivora, of which the dog may be regarded as the type ; and intermediate between the foxes and hyaenas in the system. They have three false grinders on each side of the upper jaw and four in the under, the front ones of which are sometimes shed. There are two moderately large tuberculous grinders above, only one below, and two projecting tubercles on the interior side of their foremost car- nivorous tooth below. All the rest of the grinders have their crowns more or less tuberculous. The tongue is beset with horny papillae, harder and more pointed than in the hyaMias, but not so much so as in the cats. With the exception of one of the sub- genera, there are five toes on all the feet, the claws on which are sharp and more or less retractile, but they are not very crooked. The legs are generally short in proportion to the length of the body ; and the greater number use the elasticity of the arched spine to aid them in springing on their prey. Under the tail there is a scent bag, which secretes an unctuous matter, which is, in some of the species, rather abundant, has a strong musky scent, is much valued as a perfume by the Orientals, and once formed an article in the materia medica of Europe, under the name of civet. It is now excluded from the list of medicines ; and it got a place in that list formerly, probably for no better reason than the old dogma, that " whatever seemed to have active qualities, and for which no other use could be found, must have been intended for curing some disease." In addition to this matter, of which the scent, when it has any, is generally musky, there are, at least in some of the species, two smaller openings, situated in the same part of the body, from which a dark-coloured fluid of a very disagreeable scent is discharged. When we consider the appearance, the structure, and the habits of these animals, we find it somewhat difficult to determine to which of the other families they have the nearest resemblance. In their general form, their style of walking, and also in the posses- sion of the anal scent bag, they bear no inconsiderable resemblance to the pole-cat or martin family ; many of them have also much of the air and not a little of the manners of the hyaenas ; some of them also have slightly the appearance, and all have a good deal of the manners of the smaller cats ; they also, in their form, the feet excepted, bear some slight resemblance to the badgers ; nor is it impossible to trace points of resemblance between them and the dogs. But still they have a distinctive character of their own ; and though the different sub-genera and species vary a good deal from each other, it is easy to trace a family likeness among them all. But it is much more easy to trace this likeness than to say in words in 58 CIVET. vvhat it consists, because it is a likeness of the whol character of the animals as made up of structure disposition, and habit, rather than of any one of th elements which form that character. They are all nocturnal animals ; their eyes close to a vertical line in the pupil, like those of th Common cat, and, as is the case with that animal they all glisten in dull light. Some account of thi: glistening of the eyes of nocturnal animals may b( found in the article CAT ; and we may here add, tha the reason why the eyes of the same animals do noi glisten in bright daylight, is the necessary contraction of the aperture of the pupil by the action of the light upon it. In this case, the quantity of light which gets admission to the eye is very small ; and there- fore the portion of it which the eye reflects, is noi equal to that reflected by objects illuminated in the common way ; but when the animal is under the shade, if that shade is moderately obscure, the eyes glisten just as much during the day as during the night. Animals of this genus are not entirely carnivorous, but can, when necessity urges them to it, feed upon vegetable matter, of which they prefer sweet and succulent fruits. Their proper food, however, may be regarded as being animal much more than vegetable, because the carnivorous character not only predominates in their teeth, but is more strongly marked in them than in any animals except the hyaenas and cats. They are very expert in catching birds, upon which they spring much in the same manner as cats do ; they also catch mice and other small animals with much dexterity, and in some parts of the world some of the species are kept in houses for this purpose. They have, however, other habits in their feeding, different from those of cats, for they are great destroyers of eggs. During the day, the greater number of them are exceedingly indolent, and sleep almost the whole of their time. Others, however, are more of diurnal animals, and follow at least some of their prey by coursing. They are all animals of tropical countries, or at least of countries bordering on the tropics ; they are wholly natives of the eastern continent and the adjacent islands. There is not above one species met with in any part of Europe, and that species is confined to the warmer parts of the south, and is far from being numerous there. Africa, India, and the Oriental isles, more especially the latter, are their head quarters, and it does not appear that a single species has been met with in Australia, or in the remote isles of the Pacific. From their indolent habits, and their short legs, they cannot be expected to migrate far in quest of food, and therefore they need hardly be looked for in places which are subject to seasonal barrenness. They are not aquatic animals, however, but frequent the banks of streams, the wood-lands, or the open glades, preying generally upon the smaller reptiles and the eggs of the larger in the first of those places, on birds and small quadrupeds in the second, and on the smaller lizards in the third. They are usually divided into three sub-genera — Civets, Gennets, and Ichneumons, and perhaps there are some other sub- genera which may be added. CIVETS. These have the scent bag large and deep, divided into two cavities, and producing abundantly the unctuous substance, which has a more musky scent in this genus than in perhaps any other. There are at least two principal species, the civet and the zibeth, which names have, however, exactly the same meaning, though the animals differ. The civet is found chiefly in Africa, and in the south- west of Asia ; the other species in the south-east ; and it is probable that there are several varieties of the latter, Civet. This animal is often in common language styled " the civet cat" but the name is of course inapplicable, except in some slight resemblance in the manners, in the fur on the body, and in the form of the tail. Civet. This species measures about two feet three or two Feet four from the muzzle to the tail, and it stands from ten inches to a foot in height at the shoulder. Its muzzle is produced and pointed, but not quite so much so as the fox ; the ears are short and round ; the hair on the body is long and coarse, and that which ranges along the line of the back and the upper part of the tail, forms a sort of crest, which is turned back towards the neck ; the ground colour is bright jrownish grey, with various spots and bands of jlackish brown, and the dorsal crest of the same colour ; the head is whitish, with the exception of a spot round the eyes ; the cheeks and chin are brown ; he naked part of their nose is black ; the legs and inder part of the tail are brown, the hair on the brmer especially being much shorter than that on he body ; the tail on the upper part is partially annulated. The most remarkable peculiarity in the anatomy of the civet, is the organisation of the bag containing ts peculiar scent. It opens externally by a narrow :left, situated between the anus and the parts of generation, and is exactly similar in both sexes, rt'hich renders their apparent difference but trifling. This cleft conducts into two cavities, which might sach of them contain an almond. Their internal urface is slightly covered with fine hair, and pierced ivith many holes, each of which conducts into an >val follicle of very slight depth, the concave surface f which is again pierced with innumerable pores. The odoriferous substance comes from these pores, "t fills the follicle, and when this is compressed, it iroceeds from it something in form like vermicelli, nd enters the larger bag. All these follicles are nveloped by a membranous tunic, which receives uuiy of the sanguineous vessels ; and this tunic, in ts turn, is covered by a muscle which comes from the ubis, and has the power of compressing all the ollicles, and with them the entire bag to which they CIVET. are attached. By means of this compression, the animal gets rid of the superfluous part of its perfume. Besides this odoriferous matter, there is another secreted, which assumes the form of stiff' silken threads, and is mingled with the first. The civet has besides a small hole on each side of the anus, from which a blackish and very foetid liquid issues. The odoriferous substance produced by the civet, and to which the animal owes its common name, forms, especially in the east, an object of considerable commerce. Its virtues are greatly vaunted, accord- to Baron Cuvier, among- the French, though, as we have already said, its medicinal reputation is now wholly exploded. The tail of the civet is composed of twenty-five vertebrae, which forms a difference between it and the zibeth, which has only twenty-two. We must not con- found the sluggishness of this animal during the day, with incapacity of motion, at those times when its habits require it to move ; for this sluggishness by day is common to all animals which prey by night ; and those which pursue their prey with the greatest ardour and success, are generally the most quiet dur- ing the periods of their repose. The civet is lithe and agile, and capable either of springing like a cat, or of coursing its prey like a dog, and it indiscrimi- nately catches birds and small quadrupeds. Failing these, it attacks fruits, and also the fleshy roots of plants. They inhabit plains and hills which are rather dry, and seldom drink. In many places of Africa they are kept and bred in a domestic state for the sake of their perfume, which still forms a consi- derable article of trade. The female has four mammae, but seldom produces more than two or three young. The period of gestation has not been well ascertained. Zihctli. This species is much smaller in size than the civet, and smoother in its covering ; but it is longer on the legs. Its length is about fifteen inches exclusive of the tail, and its height about a foot. It has no crest of prominent hairs along the ridge of the back ; the ground colour of its fur is yellowish grey, marked with numerous black spots, which sometimes run so much into c;tch other, as to form nearly con- tinuous lines along the sides. The tail is black above throughout its whole length, and pale grey on the under side, which is also the colour of the belly. The sides of the tail are marked with cross bars of black and grey ; the throat and breast are white, and so are the ears, a small spot in front of the eye, and the sides of the upper lip. The throat and breast arc whitish, but marked on the sides with a very conspicuous arch of black, proceeding from the hind part of the ear, and returning to the breast, but not meeting there, so as to form a complete collar. Within the arch there is a spot in the shape of the letter V, with its point directed towards the ear. This animal is most plentiful in the Eastern islands, where it is often kept in a domestic state, in the same manner as the civet is in Africa. When fed properly it is a very peaceful animal ; though it is strongly made and very active when in a state of nature. It is probable that two distinct varieties, if not species, of these animals, both natives of the Eastern islands, have been mixed up in the descriptions of this one. This species is called Taitggahmg by the Malays, and the other is called Rasse, the latter being by far the more slender of the two, and having the line on the forehead straight, the muzzle more pointed, the head and neck much smaller, and the ears much nearer to each other. It is a very active animal, very difficult to be tamed ; will not breed in confine- ment, and therefore, in order to procure its perfume, which is highly prized in the east, it has to be captured and confined in a cage. It is probable that there arc other varieties, or even species, besides these, but their history is obscure ; and, as the colours are known to be variable in the same species, and as they all have the same structure, and nearly the same habits, the distinctions of them are of minor importance. GENNETS. These have the sac in which the scented matter is produced much smaller than the civets, and though they have the musky smell, there is no visible secretion, at least in any sensible quantity. The pupil of their eyes contracts more completely to a vertical line in the light than that of the civets, and their claws are more retractile, nearly as much so, in fact, as those of the cats, only they are not so much crooked, and the paw is not so well adapted for being either a striking or a clutching weapon. Common Gi'nnct. In its general appearance, the gennet bears no inconsiderable resemblance to the common pole cat, only it is rather longer and stouter, has the line of the forehead straighter, the muzzle much thinner, the ears larger and more naked, the feet stouter and the tail longer. It is covered with two sorts of hair, the longest about half an inch in length on the body, and a whole inch on the tail. The tips of the hairs are, in some places, black, others grey, and others reddish, and the tail is marked with fifteen rings, alternately white and black, with some cloudings of red. This is a western animal, having a very consider- able range in latitude, namely, from the south of France to the extremity of Africa. They sleep, or doze in indolence, during the greater part of the day, but are particularly alive during the night. They have many of the habits of cats, and are sometimes employed as substitutes. They breed in confinement, and the period of gestation is understood to be about four months. Many other species of this sub-genus have been described, and it is probable that the Rasse of the Eastern isles should have been included in the num- ber ; but the history of the greater part of them is perfectly obscure, and therefore, not adapted for popular purposes. ICHNEUMONS. These have the anal bag large and simple, with the anus in the middle of it. They have the hair short on the head and the feet, the toes semi- palmated, and they are generally found near the banks of rivers. Common Ichneumon. Many marvellous stories have been told of the blessing which the ichneumon bestows upon Egypt, in the destruction of crocodiles and serpents on the banks of the Nile. A little more accurate information has, however, taught us to believe that the crocodile is by no means a dangerous neighbour to the human inhabitants of Egypt, neither are the serpents on the banks of the Egyptian river very remarkable for their deadly qualities ; and, there- fore, the ichneumon has lost much of its celebrity ; and in the service which it renders to man, it must take its station below the domestic cat, though it is sometimes used as a substitute for that animal. The ichneumon is rather of a timid disposition, except against mice and small lizards ; and, though it attacks the eggs of the crocodile and of other large reptiles with great courage, or, at any rate, avidity, there is no 60 CLARKIA -CLASSIFICATION. authenticated instance of its having ventured within reach of the jaws of the crocodile. The ichneumon is not so indolent during the day as the other sub- genera, and therefore it has more attraction as a domestic quadruped. It is easily tamed, remains willingly in a state of domestication, and not only obeys the call, but readily follows the footsteps of those who are kind to it. It is rather a small animal, about fifteen inches in length and eight in height. Its colour is deep brown, so mottled with dull white, and sometimes with grey, that it is not easily described. There are five toes on each foot, the thumb is very short and apparently useless. All these toes are armed with strong and crooked claws. The sole is naked and covered with a very fine delicate skin. The eye has a long trans- versal pupil, but no other particular character. The nose passes the lower jaw, but is not moveable. When the overflowing of the Nile drives the wild ichneumons from the banks, they sometimes resort to the towns and villages, to levy contributions on the poultry yards and pigeon houses (pigeons are exceed- ingly abundant all along the banks of the Nile), or to join in the labours of scavengership with the foxes and hyaenas ; but these animals not only take the lion's share of the offal, but very frequently include the ichneumon .itself in that devoted portion. The described members of this sub-genus are still more numerous than those of the former, but they are subject to the same uncertainty. Their haunts and habits are all so nearly alike, that any one of them serves to tell the tale of the others in every respect, save in external appearance and in locality. The places which they frequent, are, in all parts of the world, those in which there are periodical floodings of water ; and the principal office which they appear to perform in the economy of nature, is that of destroying the eggs of aquatic reptiles, which are, in general, so very numerous, that if they were all to be hatched the young could not possibly find food. CLARKIA (Pursh). A beautiful little annual, lately introduced into our flower gardens from North America. Linnajan class and order Octandria Mono- gynia ; and natural order Onagrarice. Generic cha- racter : calyx tubular, limb four-cleft, three of them often cohering ; petals inserted in the calyx, claws with one tooth on each side, limb of three lobes ; stamens alternately sterile and fertile, the latter op- posite the gashes of the calyx ; anthers linear, two- celled ; style filiform ; stigma of four lobes, somewhat like petals ; capsule cylindrical, furrowed, and four- celled. This plant was hailed on its first appearance, not only as a stranger, but for the elegant laciniated figure and position of its petals. It readily ripens seed, which only requires to be sowed in the open borders with other hardy annuals in the spring. The original plants had purple flowers ; but we have already a variety with white or very pale purple blossoms. CLARY. Is the Salvia sclarca of Linnaeus. This is a biennial, and cultivated for seasoning soups, &c. There are two other species of clary, viz. Horminum, of which there are two varieties, namely — the red and purple-topped, and Verbcnaca the vervain-clary. CLASSIFICATION. The productions of nature are so numerous, and the progress which the combined and continued efforts which men of all nations and in all ages have made in the knowledge of them, is so small, compared with what we are compelled to be- lieve still remains to be known, that the life of man, measured against all that has to be learned in order to obtain even a superficial knowledge of the works of nature, appears more disproportionate than measuring a single moment against a thousand years. Knowledge, of whatever kind it is, in order to be true and therefore useful, must begin as we ourselves begin, that is at the point of absolute ignorance ; and therefore, if we go to the details, and attempt to know the single subjects one by one, our lives would be spent before we had mastered all which is to be met with upon a single acre of ground in a state of nature. All appears in a state of confusion to our untutored observation ; and therefore we, in that state, abandon the study as hopeless, and fall back upon our merely animal appetites as our only means of enjoyment. This we find to be the state of mankind in all coun- tries where the light of science has never came ; ami yet in the few matters which they do understand, we find that these men of limited information are superior rather than inferior to ourselves. The senses of the savage are always more acute than those of men who are civilised and informed ; but there is no principle of progression in them — they do not advance ; and we have no reason to suppose that the inhabitants of any scienceless country were one jot better informed at the time when they were first visited by European adventurers than they had been in the hundredth generation previous to that event. Not only this, but it does not appear that there is any general tendency in them to profit by the ex- ample of their more scientific visiters, unless there has been a beginning made before the arrival of them. No doubt there are some rude people, to whom the intercourse of civilised men has given an impulse, and we cannot, perhaps, cite a more striking instance of this, than the case of the New Zealanders ; but they were begun — had taken some steps — rude no doubt, but still in the way of improvement — before they were visited by Europeans. On the other hand, where there has been no beginning, the savage is consumed before the march of civilisation, instead of being aroused and instructed by it. The Indians of North America have faded to a remnant much faster than can be accounted for by any direct oppression with which they have met — though that has no doubt been severe enough in many instances. When we turn our attention to other parts of the world, be those parts what they may, we find that there is no exception to this ; but that the longer these rude tribes have been in the neighbourhood of civilised men, the more have they fallen off in character, and declined in numbers. There is much information involved in these truths, simple as they are ; for they show that the ignorant cannot arrive at knowledge of any kind by the means and the process by which that knowledge has been originally accumulated ; and also, that the way of obtaining possession of the knowledge which has been already acquired must be different from that whereby additions are made to the stock. The record of knowledge is the index, as it were, while the original discovery is the labour of the book ; and every one must have felt the advantage that there is in consulting a book by the help of a well-arranged index. An index to the words of any one book is most convenient for consultation, when it is arranged in alphabetical order ; but an index to the productions of nature requires a different form, because each of CLASSIFICATION. 61 these singly has a story to tell, to which story, until it lias been known, no name or other word can be any guide. In this case the best, and indeed the only index that can be of use is, an inde.v of relations, — not an index to the individual facts or subjects, but one which shall, from the knowledge of one fact or sub- ject, guide us to a second, from that second to a third, and so on. These relations apply equally to n~hnt exists and to what happen*, and they are the means of knowledge, and not knowledge itself — the instru- ment, not the end. For knowledge, like every thing else, must be of the same kind with its beginning, and be stable or unstable according to the foundation on which it rests. Whether we seek to be informed, relative to the productions of nature simply as they exist, or the phenomena or changes which they dis- play in the course of time, we must have a beginning in addition to our index of relations. Our progress, to use a homely expression, is by means of a bridge, of which facts are the piers, and relations the arches ; and though we cannot pass over by means of the piers without the arches, yet the arches can have no sup- port but the piers. There are two sets of persons, each of which are in possession of one of these elements of knowledge without the other ; and for this reason they may be both said to be ignorant. Common observers have the piers of the bridge without the arches ;-and men who have studied the systems in the books have the materials of the arches, but want the piers for support- ing them ; and thus, to them, the arches are no arches at all. Their case is much more hopeless than that of the former class ; because, just as piers can exist without arches, while arches cannot exist without piers ; so facts, accurately observed, are sound know- ledge in the exact proportion of their accuracy and to the full extent of their number, whether the pos- sessor of them know the relations between them or not. But still, the piers, notwithstanding all their stability, will not carry one across the river, uidess they are brought so near to each other as to become stepping stones, which can be the case only in the thallows. Thus, though the matter-of-fact man is not so utterly ignorant as the mere theorist, he is still not in a condition to make advances in knowledge by means of the knowledge he already possesses ; and it is the capacity of converting the knowledge which we h.ive into the means, and the certain means, of obtaining more, which is most valuable. Clauificaiion, m the natural history sense of the term, always has reference to beings or existences, and not to phenomena or appearances ; though appearances are used as the means of classification ; and any clas- sification is valuable in proportion to the kind of appearance, or character as it is called, which is made the basis of it. The doing of this must depend upon the knowledge and judgment of him who makes the classification ; and as the classification is the real instrument in the acquiring of knowledge, it is essential that the man who attempts to make or to alter a classification, should possess the most extensive information, and the most sound and scrutinising judgment, upon this very simple and obvious prin- ciple, that he who does not intimately know, and justly and impartially estimate all the characters (that is the known characters) of every individual which the class includes, is riot prepared for giving a useful or even an honest judgment, as to what should be the common character of the class. This applies to all classifications, and to all the paits, primary, intermediate, or subordinate, of which they are made up ; and in the subordinate parts, those which come as near as possible to the specific distinctions, in which we consider things as identical in their natures, and differing only as individual ex- istences, it is necessary to be more accurate, and to see farther than in the grand and primary divisions. In these cases, no man has a title to alter any classifi- cation, unless he is fully prepared to justify his altera- tion through every step and stage upward to the simplest division which can be made of natural sub- stances, or even up to the simple fact of existence. And it is especially necessary to impress this truth upon all who are only beginning the study of nature, or who have made but little progress in it. The beginnings of science, though mere molehills in reality, seem mountains in the eyes of the com- mencing student ; and they seem the more so, the more earnestly and even the more honestly that he enters on the study. If we may use the expression, the eye of the mind begins the study of any thing with microscopic power, which magnifies to a very great extent ; but as the quantity of knowledge accumulates, the magnifying power diminishes, and after a long life spent in scientific pursuits, individual objects sink down in their importance, and appear insignificant in comparison with the number and mag- nitude of the whole. Hence it is, that those men who are the best qualified, and therefore the best en- titled to make or to alter classifications, always set about making such alterations with the greatest caution and reluctance. And, paradoxical though it may seem, it is nevertheless true, that all the war of systems, and all the wranglings about classifications, which have so often disturbed, and we fear we may add demented, the scientific world, especially natural- ists, have really been waged by parties, not altogether dissimilar to those who are said to have fought the first pitched battles recorded by the poets of antiquity, "the frogs and the mice, the pigmies and the cranes." With the desire of impressing this truth fully be- fore us, we shall not venture to suggest any particular classification, or any modification of one which exists, but shall confine ourselves to a very simple outline of the meaning of the term, and of the advantages which are derivable from the right use of it. Nature is so wide a field, that no one science can be made to embrace the whole of it with any thing like precision ; and therefore when we speak of natu- ral history in the proper sense of the words, we mean little else than a catalogue raisonne of a considerable number of sciences, with some slight sketch of their relations to each other. This may be considered as one primary step of classification, the beginning, as it were ; and under it we are not called upon to do much more than to explain clearly what we mean by subject or being, and what by appearance or pheno- menon. Some view of this, as it applies to the sub- jects to be known, will be found in the Introduction to this work ; and all that remains would be to men- tion the names of the different branches of science, as applied to the knowledge of those subjects. This is, however, unnecessary, because it would be impossible, without occupying more space than we can devote to it, to make it the vehicle of much meaning. The three primary subjects are, matter which neither grows nor lives, growing matter, and living matter. The first is a very extensive subject, 62 CLAUSILIA — CLAVIJA. and stretches in range beyond all but the very simplest and most elementary observation. It goes to the sun. to the planets, and it speculates to the stars ; and in all those regions which form so mighty a volume, that the earth is but a point in its humblest page, all that we can know is distance, magnitude, mass, motion, and mutual influence of one of those bodies upon another. From this vast height, in the extreme of which we are lost in the infinitude of great- ness, we descend downward to air, and water, and solid matter, whether in larger or smaller masses, and to every thing, in short, which goes to the composi- tion of our earth, and which is not immediately under the influence of vegetable growth or animal life. Nay, our inquiry into mere matter includes the sub- stance of which all plants and all animals are formed : and we can and do speak about the component parts of them, while they are entire, and growing, and living, just as though these component parts were separate portions of dead matter. Nor do our in- quiries stop even here, for it is the province and the business of the student of dead nature, to extend his observation, and apply his reasoning, from the most distant mass to which the line in the balance can be applied, down to the very verge of the primary atom, the smallness of which makes it as inscrutable to our knowledge as it does the magnitude of the other ex- treme. Within these boundaries there are situated all the sciences which are physical, including chemi- cal science among the number ; and in this grand division, the name of natural history is not generally applied to any thing but to the description of those individual masses of matter which can be distinguished from each other by their peculiar characters. But still this humble portion has its use in the system, though taken singly that use is very limited. Vegetables and animals are less extensive in their scope, because we find them only on the surface of the earth or in the waters ; and their situations are generally such as that we can go all round them and examine them, and study their progressive histories in time as well as their momentary appearances. Therefore we have many more characters in the case of them, and thus it is here chiefly that classification becomes of the greatest value, and where the abuse or the captious use of it is calculated to do the most mischief. Accordingly much time has been devoted to the classifying of plants and animals ; and the result of this labour, though of course, from the very nature of the case, not altogether or even nearly perfect, has made so much progress as to be highly valuable to the student, by being to him an instrument by the skilful application of which he can acquire more knowledge in a few days than he could without its assistance acquire in a life-time. The individual classifications applying to both of these departments will be found in the notices, gene- ral and particular, of the subjects themselves ; and as it would be contrary to the nature and object of a popular work to teach system-making, being the very subject which people should specially avoid attempt- ing, we do not feel that more words are necessary. CLAUSILIA (Lamarck). This characteristic name was, in the first instance, given to shells in which the entrance of the opening was closed at a certain depth by a moveable ovate testaceous lid, performing the office of an operculum, and supported by a thin elastic pedicle inserted in the columella. This lid closes upon the animal when it retreats within its dwelling, by means of the pedicle acting as a spring. Lamarck has not been able to ascertain that all the examples he has given of this genus are so provided, but naturally concludes they should be, and has constituted the genus from the other constant and similar characters to be observed in them, the most remarkable of which is that of the termination of the last whorl being quite detached from the base of the shell. The aperture is ovate or rounded, its edge entire, and the margin reflected outwards. These shells are all of them terrestrial, fusiform, slender, and the summit rather obtuse, to which may be added, though not mentioned by Lamarck, that the opening is occasionally dentated The structure of the animal is similar to that of the helix, but having the first pair of tentacula very short. About twelve recent species are known, the greater number of which are European, and found particularly on the borders of the Mediterranean. Several are also known from the American archipelago. Second class, Para- cephalophora ; first order, Pulmobranchutta : third family, Limacinea. CLAVAGELLA (Lamarck). This genus of shells was unknown to Lamarck in a recent state. He considered it an intermediate species between the Aspergillum and the Fistulana, differing from the former by having only one external fixed valve, the other free and internal, and from the latter, which has no perforations at the larger extremity ; this shell has also an appearance of small projecting tubes at one extremity round the disk, similar to those of the Aspergillum. Sowerby, in his Genera of Shells, No. 13, has described the only recent species of this genus supposed to be known. It is classed bv Lamarck between the genera Aspergillum and Fistulana. CLAVATULA (Lamarck). A mollusc, united to the genus Pleurotoma by De Blainville, as being no other than a species of that genus. CLAVIGER (Preysler). An extraordinary genus of coleopterous insects, nearly allied to the family Pselaphidce, having the elytra shorter than the ab- domen, and truncate ; the antenna? thick and six- jointed ; the eyes are wanting ; the maxillary palpi very minute, and apparently without articulations ; and the tarsi are three-jointed, the last joint being furnished with a single claw. These curious little insects are not above one-eighth of an inch in length, and are found under stones in dry situations ; they are likewise often met with in the nests of ants. M. Muller has published a good monograph upon this genus in the third volume of Germar's Maguzin der Entomologie, as has also M. Aube, more recently, in M. Guerin's Magazin de Zoologie. M. Dalman has described another genus, even more remarkable than the foregoing (to which, however, it is intimately allied), under the name of Articcrus, and which was discovered by him embedded in the substance so often mistaken for amber, namely, gum ammo*. The antennae are composed of a single long cylindrical joint. CLAVIJA (Ruiz and Favon). A South American tree, which, when cultivated in a dwarfed slate in our hothouses, forms a very healthy ornamental plant. Linnaean class and order, Pentandria Moiwgi/nia ; and natural order, Myrsmcce. Generic character : calyx five-toothed ; corolla bell-shaped, limb in five lobes ; stamens shorter than the corolla, on a cup round the seed-vessel ; berry having a free central placenta. CLAYTONIA — CLETHRA. 63 This plant was called Theophratta by Linn&us and other botanists. It flowers frequently, though the little purple racemes produced from the stem are not very showy. The foliage, however, is handsome. CLAYTONIA (Willdenow). A genus of tube- rous rooted perennials and curious annuals from North America. They belong to the fifth class of Limucus, and to the natural order Portulacece. The annual and perennial species are sowed or planted in the open air, and thrive best on borders of moor- earth. CLEAVERS. A very common British plant, the Galiuii/ aparinc of botanists. It receives its name from its seeds, leaves, and slender stalks, being armed with honked hairs, which cling or cleave to every- thing. It is, moreover, called goose-grass, from gos- lings being particularly fond of the leaves soon as they are hatched. It is a troublesome weed to the farmer, it being difficult to separate the seeds from the samples of corn. When these seeds are seen among corn, they are called burrs by the millers. CLEM ATIS( Linnaeus.) Herbaceous and shrubby climbers, found in manydifferent parts of the world. Lin- nasan class and order, PolyandriaPolygynia; and natural order, Ranuncnlacca:. Generic character : calyx of four to six sepals ; nectary, none ; stamens fixed below the gerrnen ; filaments, dilated at the apex ; anthers, two-celled ; style persisting, downy ; cary- opses tailed. The clematis, or virgin's bower, or traveller's joy, is a well-known European plant. It is this plant which covers our hedges in the autumn with that grey feathery substance, by which it has also gained the name of " old man's beard." It is most abundant, and grows with great vigour, in chalky districts. The presence of chalk at a great depth under the surface is often pointed out by the exist- ence and growth of the clematis. It is an embower- ing plant, and soon takes possession of the whole head of any plant it can lay hold of; the petioles of the leaves acting like tendrils, by curling round the twigs of the plant which lends support. Almost the whole tribe are attractive one way or other ; and some from the easy flowing position of their branches, and elegant tassel-like flowers are much and deserv- edly admired. The C. florida, single and double ; the vilict'lla, and crtmpanijtora, are fine plants, and merit a place in every flower garden. The hot-house species require plenty of space to flower well. CLEODORA (Lamarck, CLIO PYUAMIDATA ; Lin- naeus). A molluscous animal, but the posterior end of its body is covered by a firm, somewhat cartilaginous, straight, and transparent shell, like an in verted pyramid, or in the form of a spear, truncated and open at the upper part, of a distinct shape in different species, and not opened laterally, or at the posterior end, as in the genus Hyalcea. The body of the animal is length- ened, conical, more or less depressed, divided into two parts, as in the Hyalcva; two tentacula, two eyes, and two swimming organs at the anterior part ; the posterior conical. It differs but little from the J/i/a/cea, next to which it stands in the first order, Aporobranchiata ; first family, Thecosmnata. CLEOME (Willdenow). A genus of undershrubs, perennial and annual herbs, mostly natives of Ame- rica. Linntean class, Tetradynamia ; and natural order, Capparidtw. Generic character -. calyx of four sepals, the fourth inferior ; petals unequal, ascending, three nectariferous glands at the base ; sta- mens man}', but only a few fertile ; filaments inserted in the calyx, declining ; anthers, ovate and erect ; style, simple ; stigma, headed ; pod, slipitate or sit- ting, one-celled, and two-valved. These plants flower and ripen seeds readily ; they are easy of management, potted in light rich soil, and may be increased bj cuttings when they fail to produce seeds. CLERIDjE(Nob. ; TILLID^E, Leach). A family of coleopterous insects belonging to the section Pentamera, and sub-section Serricornes, distinguished by the dilated tarsi ; hatchet-shaped palpi, toothed jaws ; the antennae are more or less serrated, and often thickened at the tips ; the eyes are notched inter- nally, and the thorax is generally narrower than the elytra ; the body is elongate, sub-cylindric, and of a firm consistence. These insects, in the perfect state, are often found upon flowers ; many of the species, however, are only met with under the bark of rotten trees, where they have resided in the larva state. They are of a moderate size, and are gene- rally handsome insects, being much variegated in their colours. The larvae, which have hitherto been observed, are carnivorous in their habits. The genera are Clcrus, Geoffrey (Trichodes, Fabr.) ; Cylidrm, Tillus, Prio- cera, Axina, Eurypus, Thanasimiisopihis, Clerus, Nc- crobia, Corynctcs, and Enoplium. The first-mentioned genus is distinguished by hav- ing the labial palpi terminated by a hatchet-shaped joint ; the basal joint of the tarsi is nearly as large as the following, and the antennae are terminated by a three-jointed club, the last joint of which is alone ter- minally produced intoanangle. There aretwo British species belonging to this handsome genus, namely, the Attelabus apiarins of Linnaeus, which is blue, the elytra red with blue bands, the extremity being also blue. The larva of this insect is found in the hive of the common bee, where it devours the larvae of this useful insect, and thus occasions much injury to the hive. It is, however, very rare in this country. The other is the Trichodes alvearius, Fabr., very much resembling the preceding ; but the region of the scutellum is blue, and the extremity of the elytra red. Its lame resides in the nests of the mason bees (Otmia) feeding upon the grubs of these insects. CLERODENDRUM (Limueus). Shrubs and a few climbers, mostly natives of eastern Asia. Linnsean class and order Didynamia Angiospermia, and natural order Verbenacca:. Generic character : calyx five- toothed ; corolla, tube elongated, graceful, limb spread- ing, of five equal lobes ; stamens protruding, widely parted ; anthers incumbent, bursting transversely ; style long, filiform ; stigma acute, and cleft ; drupe tetrapyrene, embraced by the calyx, one-seeded. Some of this genus are splendid flowering plants, and all are more or less ornamental. They are all easy of propagation by young cuttings, or pieces of the roots. Some of the species increase themselves by suckers. CLETHRA (Linnanis). A genus of handsome hardy shrubs, natives of North America, and a few greenhouse species from Madeira. Linna^an class and order Dccandria Monogynia, and natural order Ericecc. Generic character : calyx five-parted, persisting ; petals five, spatnlate, concave, longer than the calyx ; stamens inserted in the receptacle ; fila- ments like hairs ; anthers inversely egg-shaped, opening at the apex ; capsule invested with the calyx, three celled, cells full of seeds. The hardy clethras 64 CLIDEMIA— C are usually planted in light loam, mixed with two- thirds moor earth, and are very suitable shrubs for the flower garden, and are increased by seeds or layers. C. arborea is too tender to bear the open air of this country, and is usually treated as a greenhouse or conservatory plant. The other species, from the same island (Madeira), require similar treatment, and mav all be propagated by cuttings. CLIDEMIA (D. Don). A genus of tropical shrubs, separated from the genus Melastoma, to which they are nearly related, though not so fine flowering plants as some others of that fine natural order. The clidernias are remarkable for hairiness over their leaves and stems. CLIFFORTIA (Linnseus). A genus of shrubs from the Cape of Good Hope, some of which have been long cultivated in British collections. They are Dicecious, and belong to the natural order Rosacece. They are cultivated more for the variety of foliage they give to the collection than for their flowers, which are not attractive. Young shoots strike root readily under the ordinary management. CLIO (Lamarck). A naked molluscous animal, of which only three species are named. The charac- ters of this animal are not sufficiently well known to be described with certainty ; it belongs, however, to the family of Gymnosomata. The species here figured is the Clio bnrealis. CLISIOCAMPA (Curtis). A genus of lepidop- terous insects, belonging to the family BombycidcB, distinguished by its robust thick-set bodvi short but powerful wings, which are rather acute, and its short curved antennae; the palpi are of very small size, and the spiral tongue is entirely wanting. These insects are known to collectors by the name of Lackey Moths, a name which they have gained from the gaudy stripes of various colours, with which the caterpillars are ornamented. The perfect insects are of moderate size, seldom exceeding two inches in expanse. " The larvae of C. neustria" observes Mr. Haworth, " are one of the greatest pests our fruit trees labour under. They are sometimes quite defo- liated by these voracious caterpillars, and covered over with their noisome webs. The female moth, when she deposits her eggs in autumn, agglutinates them in the neatest manner imaginable, all in close and symmetrical contact, round a twig of about one year's growth. These, hatching a little after the foliation of the tree in spring, do not separate, but live in one society, and form themselves one common web, which they enlarge from time to time, as they find necessary to accommodate their increasing sizes, communicating at length to the almost defoliated tree, a very sickly and disagreeable appearance. The best way of destroying them, and all other tree feeding caterpillars, is to shake the branches violently either with the hand or a pole with a hook to it ; L I S I O C A M P A this brings them quickly to the ground, where they are easily destroyed. Poultry, if admitted, will pick them up with avidity." — Lepidoptera Britannica, p. 129. This insect is of a reddish-ochre colour, having a darker band across the middle of the anterior wings, margined on each side with a paler colour. It is very abundant, appearing in July and August. In certain seasons, however, from some unknown cause, it is much more rarely to be observed. It likewise attacks other trees. Thus Mr. Jenyns says of it, " The pest of our hedges, which in some seasons are entirely stripped of their leaves by the larvae, and laid as bare as in the depth of winter." The oak, sweetbriar, sloe and hazel, are also subject to its attacks. The precise manner in which the eggs are so symmetrically deposited by the parent moth, has not been observed, but the form of the eggs them- selves are admirably adapted for their spiral position, being in the form of a funnel-shaped wine-glass with- out a stand, so that when they are placed together in an arched form, they fit as precisely as the arch stones of a bridge, and the cement with which they are covered is so hard, that we have repeatedly slipped them off the branch without breaking the coil. We have also noticed that, although the out- side of the eggs is of a dark colour, occasioned by exposure to the atmosphere, smoke, &c., yet the partition between each egg is beautifully iridescent. It may also be mentioned, that as this cement is neither soluble in water, " nor in any other liquor, " says Swammerdam, "which I have tried," they are well defended, in their exposed situations, against the wintry blasts and rains. The curious motions of these caterpillars have attracted considerable attention amongst the obser- vers of nature. Bonnet, who noticed a nest of caterpillars, evidently of the lackey moths, observes, " I remarked that the sound of my voice appeared to incommode them, for when I spoke they briskly agitated, with repeated jerks, the fore part of the body." He is disposed, nevertheless, to suppose thu it was not by any power of hearing, but by the deli- cacy of their touch, that the sound of the voice was communicated to them. On the other hand, the author of Insect Miscellanies has suggested that this jerking motion was for the purpose of producing a rent in the skin near the head "as it was more remarkable just before their moulting than at any other time. This also, as it happens, was the very period when Bonnet made his observations, as he expressly says, ' some of them had undergone, and others were about to undergo, their first moult.'" Mr. Stephens, however, seems to refer their jerkings to atmospheric causes. "In changeable weather, I have observed," says he " that all the individuals which happen to be resting on the outside of the nest, simultaneously and repeatedly elevate the an- terior part of their body." For our own parts, we feel inclined to refer these motions to another causo ; it will be seen that it is the larvae on the outside of the nest which thus jerk themselves about ; we would therefore suggest that it is for the purpose of defend- ing themselves from the attacks of, and driving away any wandering Ichneumon fly, that they thus keep themselves in constant motion. The other British species, Bombyx caslrensis, is much more rare than the preceding, which it nearly resembles. It is figured by Mr. Curtis in his British Entomology, plate 229. CLISIPHONTE — CLOVE. CLISIPHONTE. A genus of shells constituted by De Montfort, and united by De Bluinville with the genus Lenticulina. It is only known in a fossil state, and is a microscopic shell. CLITHON. A genus of shells established by De Montfort, and now united to the genus Nerita, of which it forms a subdivision. CLITORIA (Linnaeus). A tropical genus of leguminous climbers, with pretty little papilionaceous flowers, which are produced abundantly if the plants are allowed heat enough. They sometimes ripen seed, from which young plants are raised ; or in default of them, they may be renewed by cuttings. CLIVEA (Lindley). A lately introduced hexan- drious plant from the Cape of Good Hope, named in honour of the present Duchess of Northumberland. Generic character : flowers in an umbel ; perianth tubular, six-parted, deciduous, parts connivent, the exterior shortest ; stamens inserted in the tube, equal with each other, and with the tube ; anthers versatile ; style filiform ; stigma trifid ; berry of one seed. This plant has some resemblance to CyrtantJuu; but differs from that genus in having versatile anthers, and a one-seeded berry. The bottom of the stem is but very moderately bulbous ; grows best in rich loam, and requires a temperate part of the stove to flower in. As it has already ripened seeds in this country it will no doubt soon be in every collection. It was called Imatophyllum by Dr. Hooker till it flowered, and was described by Dr. Lindley. CLIVINA (Latreille). A genus of coleopterous insects, belonging to the section Pcntamcra, family CarabidcB, and sub-family Scaritides. These insects are of small size, narrow form, with the thorax sepa- rated from the elytra by a narrow peduncle ; the fore legs are pal mated, and formed for burrowing. They are found under stones, at the roots of trees, in damp situations, beneath rejectamenta of floods, &c. There are two British species, one of which, the Tcncbrio fossor, Linnaeus, is about a quarter oi an inch long, and of a black pitchy colour. By the French entomologists, the genus Dyschirius o Panzer, &c. is united with the preceding; it is however, distinguished by the globose form of the thorax, and some other characters. There are about a dozen British species ; of the latter, some of whicl are amongst the smallest insects belonging to the CarabidcE ; they are found on the sea-coast, the banks of streams, &c. Their habits are very voracious preying upon other insects. CLOTHO (De Faujus). A fossil shell of an ova form, subregular, longitudinally striped, equivalve subequilateral hinge, formed by one bifid tooth, hook shaped, rather larger on one valve than the other the ligament external. CLOUDBERRY is the Rubus chamcemorus o Linnaeus. This plant is found on the mountains i the north of England and Scotland, and is a lov bramble-looking undershrub. It belongs to the na tural order RosaceLLLLLk L- ^ttlSfSsc H^fei^S^^. I The mode in which the ridges of this cocoon are formed with perfect regularity, is indeed inconceiv- able. Some idea may however be obtained of it from the twa following figures. Here M, i, E, represent three longitudinal ridget, and MI, IE, the intermediate space; the caterpillar commencing at E, extends a thread to H, from H to i forming an angle, from i it then proceeds to K, and from K to H, forming another acute angle, and then from H to T, and T to i, forming another obtuse angle. It then proceeds in the same manner from I coc to M, as it had from E to i, and in this manner pro- ceeds until it has nearly formed half its case, when turning round, it begins at the other end, and at length unites the two halves together, " thus inclosing itself," as Lyonnet says, "en une jolie cage" of net- work, which occupies only half an hour in the con- struction, but which is subsequently rendered much more firm by a strong layer of silk within. The other instance which we propose to notice, is that of another small moth (Microsetia ruficapitelln), the larva of which forms the curious lines of a brown colour, often to be noticed upon rose leaves, by eating away the internal fleshy part of the leaf, leaving the two surfaces entire. When full grown it eats its way out of the leaf, and crawls down the branches and stem, until it has found a convenient place to fix its cocoon, which is formed by stretching out its body, and attaching a thread to the branch ; it then crosses its body to the other side, and there fastens it. By proceeding thus on all sides, keeping the hinder part of the body fixed, it forms the upper part of the cocoon, or that exposed to the weather, which is convex, and generally circular; the under part is oblong-shaped to hold the pupa, and much smaller than the upper, which projects considerably beyond it on all sides, so as to form a defence against the rain, somewhat after the fashion of a parasol. At one end the threads are not interwoven, and leave a space through which the pupa can force a passage. This remarkable cocoon is very flat, and at first of a pure white, but soon assumes a dark colour. It is formed towards the end of October, and the moth appears in the middle of the following May. It is an elegant little creature, the upper wings being gold coloured, with the extremity purple, and the head red. The expansion of the wings is nearly a quarter of an inch. E. W. Lewis in Entom. Mag., vol. i. COC OS (Linnaeus). A genus of palms, and cer- tainly the most useful of all of them to the inhabitants of the countries where the trees naturally grow. Linnaean class and order Monaecia Hexandria, and natural order Palmcc. Generic character : flowers androgynous, that is, male and female are on the same plant ; calyx of three sepals ; corolla of three petals ; stigmas sitting ; drupe fibrous, shell with three pores at the base ; kernel equal in thickness, and hollow ; embryo within the pores at the base. This magnificent tree gives a peculiar character to the scenery of the country to which it is indigenous. The vast number of the trefcs crowded together, the height and equal diameter of their branchless stems, the spreading tuft of fronds which crown the head like an immense umbrella, together with the bunches of fruit suspended from among the footstalks of the fronds, forms altogether a spectacle the most imposing. The coast of the beautiful island of Ceylon, and that of Coromandel from Cape Comorin to Balasore at the mouth of the Ganges, is embellished with groves of cocoa-nut trees at shorter or longer distances from each other. To the voyager along these shores, the tree under notice is certainly the most prominent feature, and when he lands and enters a grove of them he feels astonished at their numbers and height. The tree serves many purposes of the inhabitants. The regular form of the stem makes it easily convert- ible to the purposes of building, fencing, or the like ; and though the grain is exceedingly porous and coarse, the wood is notwithstanding very durable. The leaves or fronds make excellent thatch for their OS. 75 huts ; the outer covering- of the nnt, after being macerated or soaked in water long enough to dissolve the pulpy cellular matter, leaves the mass of fibres, after some further preparation, fit for spinning into cordage, coarse wrappers for packing, and many other purposes. The shells are easily manufactured into various sorts of cups, &c., and converted into button- moulds, for which last purpose the substance is suit- able, except that it discharges a brown colour when used on white or light coloured garments. When the nut is quite ripe, by opening one or two of the bottom pores, a fine pleasant flavoured fluid issues which is called " milk," and when the nut is split, a part not so fluid as the milk, nor so solid as the kernel, and easily scraped off with a spoon, is called the "cream," accounted a delicacy. Next follows the kernel, serving for more substantial food, and which many partake of as diet. But the principal use of the tree to the inhabitants of India is the refreshing beverage drawn from it. and after fermentation drank under the name of " toddy.1' To obtain this, a part or the whole of the raceme of fruit is sacrificed. Soon after the fructification appears and begins to bend downwards below the fronds, the point is cut off, and to the stump is slung a pitcher- like vessel to receive the flow of sap from the wound. When one vessel is full it is replaced by an empty one, and this is continued so long as the sap flows freely. The place where this drink is manufactured is called by the English " a Toddy Tap," and where any one may be supplied with a draught on very low terms. The labourers who attend the bleeding of the trees have perhaps a score or two under the operation at the same time, so that considerable quantities are got together in a large vessel to be fermented at once. This drink is most suitable for labourers and tra- vellers in such a warm climate, for while it allays thirst it does not inebriate, a circumstance of no small advantage to the tippler, as almost all are inclined to be in that thirsty land. But here the art of the dis- tiller is brought into action : an ardent spirit may be drawn from the toddy, which serves for other and far less sanatory purposes than merely quenching thirst. Another valuable extract is procured from the cocoa-nut, namely, an useful oil, which is manufactured and sold at a reasonable price. The Cingalese, it is said, have a mode of extracting some nutritious mat- ter resembling sago from the heart of the stems, but the process has not as yet been clearly detailed. The cocoa-nut has the property of keeping sound for a long period ; it has consequently been readily transmitted to every clime where it has a chance of succeeding. Already the West Indies and other warm parts of America possess the cocoa-nut in abundance, and from thence and other places Europe is supplied with the nuts in great plenty. It may here be asked, how do the almost naked natives manage to climb those lofty and branchless trees so readily? This is a very simple though expert ma- noeuvre. The climber first binds his ankles together with a soft bandage, the toes turned outwards, so that the hollow of each foot may cling to the circular sur- face of the tree. His head and upper part of his body is raised through a strong collar of rope which surrounds both the body of the tree and that of the man. This collar is rather slack and held on each side by the hands, the body being sustained by that part of the rope which passes round the climbers 76 CCELIOXYS- loins. The first movement is leaning back on the collar and lifting the feet one step upwards, next by a sudden spring of the body towards the tree he jerks up with his hands at the same instant that part of the collar on the opposite side of the stem, by which he gains a higher hold. These alternate movements enables the climber to raise himself to the height of forty or fifty feet or more in a few minutes. The empty vessel which is slung at his back while he ascends is exchanged for the full one at top, and the last brought down to be emptied. The climber de- scends by reversing the movements he employed in ascending with considerable celerity and in perfect security. Without this mode of climbing it would be impossible to get either toddv or the nuts when wanted, applying ladders to such lofty trees is totally out of the question, for they could not be used in such woods. The cocoa-nut plant is raised from the nut and kept in hothouses, but requiring much room are in- convenient in such collections. CCELIOXYS (LatreilleV A germs of hymenop- terous insects, belonging the division Aculeata, sub- division Mellifera, and family of the bees, having the scutellum bidentate, the wings with only two complete sub-marginal cells, and the body destitute of pollini- gerous organs ; the abdomen, moreover, is of a conical shape (whence the derivation from the Greek of the generic name) ; in the males, also the extremity of this part of the body is toothed, and in the females it is cleft and gaping. From the want of organs for col- lecting pollen, these insects are evidently parasitic ; indeed the Count St. Fargeau states, that it is chiefly in the nests of several of the woolly-bellied bees, Megachile, Anthidium, Osmia, &c., that, cuckoo-like, they lay their eggs. The genus, although containing not more than a dozen species, is distributed over the different parts of the world. They are often to be found on flowers. There are three or four British species, including the type, Apis conica of Linnaeus, the female of which differs so much from the male, that it was considered by that author, as well as Fabricius, as a distinct species. It is of a black colour, with the abdominal segments margined with white. CCELOGYNE (Lindley). An orchideous genus from the East Indies. Linnaean class and order Gynandna Monandria; and natural order Orchidece. Generic character : sepals distinct, spreading, the exterior ones oblongly egg-shaped, interior linear ; labellum hollow, three-lobed, fringed, double crested, and articulated with the column ; column kneed and winged ; stigma two-lipped. This, like its congeners, has curious flowers, grows well in loose turfy moor earth, and does better in a frame or pit than in a house. It may be increased by division of the root. COFFEA (Linnams), is the tree which yields the fruit, of which the favourite beverage, coffee, is made. Linnaean class and order Pentandna Monogynia; natural order Rubiacece. Generic character : calyx small and five-toothed ; corolla funnel-shaped ; throat naked ; stamens protruding ; stigma divided ; berry two-seeded. This celebrated plant is named from a place where it grows spontaneously, namely, near the town of Caffa, in Arabia. It is now extensively cultivated in many of the European colonies, both in the East and West Indies; and indeed in every climate suitable to its growth. The tree is middle sized, of a light regularly branched habit, COLEOPTERA. and formal outline. The berries are collected by hand, dried, and manufactured till fit for use. The coffee plant thrives well in our stoves, and if allowed plenty of pot-room and water, with the necessary temperature, flowers and fruits abundantly. It is increased by cuttings, which, according to Mr. Sweet, come into flower sooner than seedlings. COLCH1CUM (Linnaeus), is the meadow saffron of English writers. It belongs to the sixth class and third order of the sexual system, and to the natural order Melanthacece. The meadow saffron or colchi- cum are bulbous rooted plants, and found in many parts of Europe. Their flowers have a strong external resemblance to those of the crocus, though they differ much in botanical character. One is a native of Britain, producing the flower in autumn, and followed by its large foliage in the spring. They are chiefly met with in meadows of diluvial soil ; but are not esteemed by farmers as a pasture plant, from the supposition that the leaves are injurious to dairy cows. A powerful medicine is prepared from the bulbs. The garden varieties and species are increased by seeds or offsets. COLEOPTERA (Aristotle, Linnaeus; ELEUTHE- RATA, Fabricius). An order of insects of very great extent, having the wings inclosed in a case, composed of a pair of scaly pieces, meeting along the back in a straight line. The wings themselves are of a large size, and of a membranaceous texture, and when un- employed are shut up in several transverse folds, the first of which occurs beyond the middle, These scales are termed elytra, and shutting upon the back, they conceal the upper surface of the abdomen, as well as the wings, from view. The insects themselves are for the most part known by the name of beetles, although the term is not exclusively applied to them. Thus The blister-fly (Cantharis) is a coleopterous in- sect, as well as the turnip-fly (Haltica nemorum). If we examine a butterfly, a bee, or a dragon-fly, we shall at once perceive that the elytra of the latter do not exist as such, but that their place is occupied by a pair of large wings, of similar consistence with the following, and being equally with the latter destitute of folds. Comparing these insects with any coleop- terous insect, as for instance a cockchaffer, it will be easy to perceive the latter distinguished by the following character. Wings two, membranaceous, folded transversely beneath tivo horny elytra, which character precisely corresponds with the Greek name Coteoptera, and the Latin one of Vaginipennes, given by the Latin naturalists to these insects. As, however, we attend to more minute differences of structure, we perceive the necessity of still more rigorously fixing the limits of our groups, by the employment of other characters, without which we should confound the locust, the grasshopper, the cicada, and the cimex, with the coicoptera ; and indeed in the early works of the great Swede, Linnaeus united the two former insects, together with the generality of those which form the modern order of Orthoptcra, with the beetles. And even in his last work, we still find the earwig united with them, although the others were separated to form the ill-assorted order of Hemiptera, which order Linnaeus had at first well defined, to comprise only those species which have an elongated tubular rostrum, articulated and bent beneath the breast. Now the coleoptera, as well as the orthoptera, differ from these in having the mouth formed of jaws and other organs for mastication. If therefore to the COLEOPTERA. 77 above character we add, mouth with jaivs, all doubt as to the admission of the hemiptera is removed. An attentive comparison of the wings and wing covers, Would unquestionably have led to the same result; but that now mentioned is not only much more simple and uniformly existent, but is also evidently dependent upon much more important considerations than the form of the wings and elytra. In like man- ner the differences existing between the oral organs of the coleoptera and the orthoptera might be resorted to, but another and more important character is at hand. Thus the orthoptera, in their passage to the perfect state, undergo no other change than the casting of the outer skin, and the gradual develop- ment of organs of flight, whilst in the coleoptera the metamorphosis is complete, and the pupa state quite inactive. Hence by the addition of the character, jutantorpkans, <>•• raihcr pupa, incomplete, we have three leading characters, which will not only separate the coleoptera from the fly, the butterfly, the cimex, &c., but also from those insects which have been by some authors united therewith. It is to be observed, how- ever, that the first of the above characters does not exist throughout the entire order ; thus in certain, although few instances, both wings and elytra are entirely wanting, as in the glow-worm and the female drilus; in others the elytra, though existent, are soldered together without any wings being concealed by them, as in many of the Carabidce, Klapsidte, and other terrestrial darkling beetles, which have no use for wings. There are in like manner to be found ex- ceptions to the transverse folding of the wings, in the Buprestldce and some of the longicorn beetles, whilst in Meloe one elytron partly laps over the •other, and in Sitaris, Rijnpliorus, &c., the suture is not straight, the elytra not shutting together, whilst in Atrctctocerus, Molorchm, &c., the wings are not covered by the wing covers, from the reduced size of the latter. Still there are sufficiently strong indi- cations of direct affinity between all these insects, and others belonging strictly to the order, so that it is impossible not to perceive that they equally belong to it, although -they form exceptions to one out of several of its leading characters. Scarcely any branch of natural history has been so much investigated as this order of insects ; indeed many students, as well as amateurs, have exclusively •devoted themselves to this group. The amazing variety of form ; the richness or agreeable disposition in their colours ; the great number of modifications which their external organisation presents to our view, and which consequently afford so many addi- tional aids towards their classification; the circum- stance that these animals generally surpass in size the remainder of the class to which they belong, and the ease with which they are preserved, owing to the greater consistence of the outer covering, all tend to render the coleoptera interesting to the student ; but to these circumstances may be added the vast extent as regards the number of species contained in the order. It would, indeed, be difficult correctly to judge of the number of these insects, distributed over the surface of the globe, each arrival from foreign climes bringing hosts of novelties to our cabinets and not only is it from the little frequented countries either of the old or new world that these importations arc derived, but every year adds considerably to the lists of our indigenous species, by the discovery o: umlcscribed beetles. Many persons have hence been nduced to believe, that a new creation was constantly *oing forward, or that from the admixture of species, ivbrids were produced. The latter is a difficult question to solve, but analogy, derived from well authenticated and long known species, induce us to object to such an idea. In order to account for this ntroduction of novelties, it is to be noticed, not only that the number of actual collectors of insects is wonderfully increased, as well as the modes of col- lecting greatly improved ; moreover, in all our large maritime and commercial towns, the productions of foreign climes are to be found in great abundance, and with them are evidently introduced an immense number of wood, plant, or grain-feeding insects, which in favourable circumstances multiply and become acclimated amongst us ; hence it happens that the vicinity of large towns exhibits a richer list of species than more thinly peopled districts. It is however unquestionable, that the coleoptera exceeds in point of number of species, any other order of insects, although the diptera and hymen- optera, now that more attention is being bestowed upon the minute species, are not far behind the beetles in point of numbers. The French collections are estimated to contain not fewer than 30,000 dis- tinct species of coleoptera, and it is by no means improbable that at least '20,000 more are contained in the cabinets of other countries, wanting in the former. Thus 50,000 species may be considered as actually existing in our collections ; and when it is known that immense tracts of country in Asia, Africa, North and South America, New Holland, and the Islands of the Southern ocean exist, from which not a single insect has been received, we may without exaggeration conclude that there are from 100,000 to 150,000 species of beetles in existence. This number, however, will scarcely be considered over- rated, when it is further mentioned that in our own little island upwards of 3,500 native species have been actually described. In the series of insects the coleoptera also seem to possess a certain degree of superiority, which places them in the foremost ranks of the class to which they belong. An eminent French naturalist, M. Marcel de Serres, has not indeed adopted this opinion ; the orthoptera, whose anatomy he has pro- foundly investigated, being in his ideas entitled to be placed at the head of the class, his opinion being founded upon a consideration of the superior develop- ment of the locomotive organs. Latreille however has considered that too much weight has been given to this character, and has suggested, from a general consideration of their comparative anatomy, that the coleoptera are the most perfectly organised of insects, and consequently as being entitled to the highest rank. We will now proceed to give a rapid sketch of the external anatomy of these insects. The body consists of the head, a large segment which has been generally termed the thorax, two short inconspicuous segments which support the wing covers and wings, and the two posterior pairs of legs, and which form a portion of the true thorax ; and lastly, a continuous series of rings which compose the abdomen, and which are not furnished with locomotive organs. The head is generally of a rounded form, furnished with a pair of antennre, extremely varied in their form in the differ- ent familes, but which in the majority consist of only eleven articulations; they often differ in the sexes. COLEOPTERA. those of the males being larger, longer, or laterally more developed than in the other sex, The eyes, which are always composite and facetted, are gene- rally larger and globular in the carnivorous species, as well as in those which, from the slowness of their habits, have great need of defence against their enemies. Some species have been asserted to possess the simple eyes (ocelli'), observed in the hymenoptera, &c. ; but Latreille does not consider that any species possesses these organs ; and indeed, as he is induced to suppose from a comparative examination of the eyes of insects, that the presence of these ocelli is an indication of optical weakness, their non-existence in the coleoptera seems to confirm his opinion of the superiority of these over other insects. The mouth consists, as in all masticating insects, of an upper lip (labrum, «), a pair of horny jaws moving horizontally (mandibles, b), two other jaws (maxilles, c) of a less firm consistence, but more complex in their organi- sation, bearing a palpus (rf) or feeler, and furnished moreover with a lateral lobe, which occasionally assumes the appearance of an additional palpus, and lastly a lower lip (labium, e), furnished with a pair of palpi (/), and implanted upon a broad horny basal piece, which is termed the chin or mentum (g). The thorax, as usual, consists of three segments, but the first of them, or the prothorax, is so much developed at the expense of the second and third, that the only conspicuous part in the meso-thorax (or second segment), is the part usually termed the scutellurn, whilst the meta-thorax (or third segment) is reduced to a short and almost obsolete ring, giving support to the pair of wings and the third pair of legs. The legs articulate with the posterior extremity of the segments, to which they are attached beneath, by means of a short piece termed the trochanter, which in the hind legs is more voluminous, forming indeed, occasionally, a large plate, sometimes moveable, but at others soldered to the segment, of which it appears to form a part ; indeed in the water beetles, the large trochanters of the hind legs have been mistaken by some of our first entomologists for the sternum ; this piece is followed by another email joint, the coxa, which is succeeded by the femur or thigh, which is the strongest part of the leg, and the tibia or shank, a piece generally of nearly equal length with, but more slender than, the preceding, the last portion of the leg consisting in an articulated piece called the tarsus, the number of articulations of which varies from three to five. The abdomen is attached to the meso-thorax by its entire breadth, its inferior portion or the belly being always more solid in its consistence than the upper surface, owing to the latter being defended by the wing covers; it is moreover pro- vided on the under side with only six segments, whPst on the upper seven or eight are visible. In gome insects, however, as the rove beetles (Brack- elytra), which have the abdomen for the most part exposed, the upper surface is as firm as the lower. The additional segments of the body, two or three in number, which are to be observed in the body of the larva, compose, in the perfect beetle, the organs of generation. The metamorphosis of the coleoptera, or rather its character, as derived from the state of the pupa;, is termed incomplete. The larva resembles a soft fleshy worm, having the head and upper surface of the tho- racic segments scaly, and provided with six legs, attached in pairs to the three anterior segments of the body. The head of the larva exhibits, in an un- developed manner, nearly all the parts of the mouth of the perfect insect. In the place of the facetted eyes, are to be seen a number of small granular tubercles, which somewhat resemble the ocelli of the hymenoptera, &c., being often six in number on each side of the head. The jaws are much more developed than the other parts of the mouth, which is doubtless owing to the circumstance, that it is in the larva state that the greatest supply of nourishment is taken by the insect. The antennae are very small and conical, and generally only four-jointed. The more inactive and concealed these larvae are, the more they exhibit the appearance of a worm ; those of the more carnivorous species are generally more alert, and in the rove beetles we have seen that they exhibit very much of the appearance of the perfect insect. The extremity of the body of these larvae is often furnished with a fleshy retractile tubercle on its under side, which is employed as a seventh leg. When the larva has attained its full size, it generally burrows into the earth, where it hollows out an oval cell, within which it is transformed into an inactive pupa, of an uniform whitish colour, with the wings and legs folded upon the breast. The pupae of some of the species are, however, naked, as in the Chrysomelidce, whilst others, as Clythra, pass this state within the case which had served for their abode whilst larvae. The duration of these transformations, the habitations and economy both of the larvae and perfect insect, varies, as may well be supposed, in so extensive a group, in the different families and genera. Arrived at their last state, they possess their full degree of development, and now the reproduction of their kind is their chief employment. Compared, however, with many other tribes of insects, as for instance the bees, ants, wasps, ant-lions, &c., none or but very few beetles present in their habits any of those extraordinary traits of instinct which have so much engaged the attention of obser- vers in every age and country ; still, however, even in this respect they are not without interest, as we have already seen in the articles CICINDELID^E, COCCINEL- LID.K, CERAMBYCID^E, &c., and as we shall have to show in many other instances. Hardly any coleopterous insect has been employed in the arts, but it is questionable whether some of the species might not be rendered useful. The meloe and the coccinella emit from the mouth and eyes a gummy fluid of a fine yellow colour, which might be employed in painting. The former insect is of a large size, and sufficiently abundant for experiment, if some of our celebrated chemists would not think the subject beneath their notice. In like manner tho Mylabris, Cantharis, or Carabus, might furnish an use • ful extract of a fine colour. We have already in our articles upon these insects given an account of their COLIAS — COLIUS. 79 medicinal properties. It is not improbable that many other species possess similar powers. Less useful but highly ornamental, the metallic coverings of many species may be and indeed have been employed in decorating various kinds of trinkets, giving an effect equal to that of gold or precious stones of every shade. By the Indians they are employed to deco- rate the head-dresses and necklaces, as well as for earrings, fee. ; and we have seen, in a large \varehouses in London, entire dresses decorated with the elytra of the Suprcstis chrysis. The larvae of the Coccincllidte are eminently serviceable in checking the swarms of Aphides, whilst the Stiphida: and many other insects, by feeding upon decaying vegetable and animal matter, are active agents in keeping up the regular succession of changes in the creation. The coleoptera have been divided in different manners by various authors. By Linnasus the con- struction of the antennae formed the character upon which the sections were established, but the distribu- tion more generally adopted by modern authors is founded upon the number of joints in the tarsi, as follows : — Sect. 1. Pentamera, all the tarsi having five joints. Sect. 2. Hetcromera, the four anterior tarsi having five, and the two posterior having only four joints. Sect. 3. Tetramera of the French authors, having apparently only four joints in each tarsus. Sect. 4. Trimera of the French authors, having apparently only three joints in each tarsus. It is to be observed, however, with respect to the two latter groups, that there is a minute rudimental joint at the base of the terminal joint which has been overlooked, and which renders the names Tetramera and Trimera incorrect ; still the general structure of the tarsus in these two groups is so well marked that we have not hesitated to adopt them ; and, secondly, that the section Dimera founded upon an incorrect examination of insects supposed to have only two joints (the Pselap/iidce, see BRACHELYTRA) is equally incorrect, and consequently rejected. COLIAS (Fabricius). A genus of lepidopterous insects belonging to the section D'mrna and family PapUionidce, or true butterflies, having the hinder wings extended beneath the abdomen, so as to form a kind of canal on which this part of the body rests, the claws of the feet are small and bifid, each having two equal sized hooks ; the palpi are short and very much compressed ; and the antenna; are terminated by an elongated conical club, gradually increasing to the tip. The anterior legs, which in some of the butter- flies are of a small rudimental size, are here fully de- veloped. The caterpillars are fleshy and cylindrical, without either tubercles or the fleshy forked tentaculae which arm the neck of the larva? of the genus Papilio. These butterflies, which formed portion of the Lin- naean section Danai candidi, are more gaily coloured than the allied insects composing the genus Pontia, including the common white butterflies, being espe- cially distinguished by the bright yellow or orange colour, which in a remarkable degree pervades the whole group, thus evidencing the curious fact of the prevalence of peculiar colours in peculiar groups of animals. The genus is likewise interesting on account of another peculiarity. " Several papilionaceous insects," observes Mr. Stephens, " are remarkable for their periodical or irregular appearance, and none more conspicuously so than the insects of this genus. The cause of this interesting phenomenon appears inexplicable, its solution has baflled the inquiries of entomologists, and several speculative opinions have been advanced thereon. By some persons their sudden increase has been attributed to the previous failure of their natural enemies, the ichneumons and the soft-billed birds ; by others to an increased tem- perature ; others again suppose that their eggs lie dormant till called into life and vigour by some extra- ordinary latent coincidences. But all these opinions are mere conjectures, and they do not sufficiently clear up the difficulty, which is rendered more obscure from the fact that several of the insects, especially Cynthia cardui, appear constantly in some parts and periodically in others." — Illust. Brit. Ent. vol. i. p. 10. The genus is a very extensive one, as regards the exotic species, but great confusion has occurred respecting the English ones. Thus whilst Stephens gives four, Curtis admits only two. We will not enter into the points involved in the determination of these questions at issue, further than to mention that, besides several other minor points of inquiry, the limits of specific variation, as well as the geographical range of insects (two most interesting subjects), are both included therein. COLIUS — Coly. A genus of birds, regarded as being wholly or chiefly granivorous, and as such ranged by Cuvier in the conirostral division of his great order Passeres. All the known species are African birds dwelling chiefly in bushes and thickets, and we are but little acquainted with their manners. The name signifies " little crow." The characters are : the bill thick, short, stout, convex above, flat below, a little compressed towards the point, upper mandible lapping over the edges of the lower one ; nostrils small, basal, lateral, round, partly covered with feathers, and pierced in the horny substance ; feet of mean size, with four toes, three to the front, united to the first joint, external toe longer than the tarsus, the hind toe short and reversable, and the claws very crooked ; the wings very short, the first quill merely rudimental, the second shorter than the third which is the longest in the wing. These birds are confined to the tropical regions of the old continent, though they, or others very much resembling them, are also met with in Australia. Being bad fliers, and capable of only short flight, these birds seldom venture out of the shade of the trees, but prefer running along the branches, which they do with great dexterity. They are said to eat buds and fruits, and to refuse insects ; and therefore they are very annoying to various kinds of cultivated fruits, and are attacked with great avidity by cultivators. From the weakness of their wings, these birds are incapable of making long migrations, or proceeding to any considerable distance from the woods in which they have their principal residence and where they build their nests, as the structure of their feet is not well adapted for walking, any more than their wings are for flight. They live in societies, and every bush contains a considerable number of families which build their nests close to each other in the very centre of the bush, which is done to protect their young from birds of prey. The eggs are three or four in number, in each more of a reddish or brownish colour according to the species. When it is not nesting time, these birds repose perching ; and it has been said that, in order to sleep the more soundly, they suspend themselves by their claws with their head 80 COLLET ES— COLOUR. downwards, the descent of the blood to which stupifie them so much that against morning- they are easily captured. It does not appear that there is muc truth in this ; for the vascular system of those animal which repose in an inverted position is always s contrived that they can bear that position withou any injury. As many as eight species of these bird have been described, varying in length from about foot to half that measure, and differing considerabl; in colours ; but the particulars of them are too imper fectly known to be of much interest to the genera reader. COLLETES (Latreille). A genus of hymeno- pterous insects belonging to the section Aculeata, sub- section Mellifera or bees, and the family Andrenidc or short-tongued bees. The insects composing thi genus do not live in society, and consequently then are no neuters ; the basal portion of the lower part o mouth (nientuni) is long, but the fleshy part at its extremity is short and bilobed, having two latera fleshy and slender appendages ; the upper wings have three complete submarginal cells, of which the second and third are of nearly equal size, each receiving a recurrent nerve, and the body is hairy This genus of bees, of which there are three or four British species (including Apis succincta, Linna?us, the type of thp genus), presents several interesting pecu- liarities both of structure and habits. In our first volume (see pp. 361, 862) the mouth of the hive bee is figured, the terminal parts of which will be seen to be of a very elongated form ; but in the genus of bees now under consideration these parts are so very short that in this respect it much more nearly approaches the wasps than it does the bees, and accordingly Mr. Kirby places it at the commencement of the family. And here we may take the opportunity of correcting an error which unavoidably occurred relative to the figures above referred to. At p. 362 three views of the mouth of the bee are given in the progress of gradual extension. These should have been suc- ceeded by the figures of the " bee's mouth " in p. 361, which represent the same organs still more completely extended, but which were accidentally misplaced, so as apparently to illustrate the structure of the mouth of the larva, after the description of which they are placed. In the left hand figure of the two last men- tioned, the tongue and its various parts are more protruded than in figure 3, the different organs on the left side of the figure being laterally extended, whilst the right hand figure represents the mouth at its greatest possible extension. The peculiarity above noticed in the structure of the mouth of the colletes, seems calculated, as Mr. •Kirby well observes, in his invaluable monograph upon the English bees, to assist it in the construction of the membranaceous cells, which the wise Author of nature has instructed it to form for the reception of its eggs ; an account of which, from the work of Reaumur, he introduced into his monograph, without, however, having been himself fortunate enough to meet with the nests. The author of this article has been more successful than Mr. Kirby, having more than once discovered the nests, and reared the colletes, and can therefore testify to the correctness of Reaumur's account. Our nests were, however, found in hot sandy banks, thus differing (perhaps from a difference in the species) from those observed by Reaumur. They make their nests, as the latter author informs us, in the earth that fills the vacuities of certain stone walls ; some of them choose a northern aspect sheltered by trees ; these nests are cylindrical, and consist of from two to four cells, placed end to end, each of which is shaped like a thimble, the end of the second fitting into the mouth of the first ; the cells are not all of an equal length, some being five, others only four lines long ; their diameter is about two lines. The cylinder usually runs in a horizontal direction ; but sometimes, from the intervention of a stone or other obstacle, it takes a different course, so that the last cell or cells form an angle with the first; it is distinguished by transverse bands of different colours. The cells are composed of many layers of a very thin and transparent mem- brane ; the red colour arises from the substance with which they are replenished, this is sometimes nearly liquid, at others it is merely a paste made of pollen and honey. After the larva is hatched, it soon im- bibes all that is liquid, and when arrived at its full dimensions, it quite fills its cell ; it resembles the larva of the hive bee. Whence these bees procure the membrane with which they form their cells, our author could riot ascertain, but he conjectures it to be a secretion of the insect, analogous to that used by many others for similar purposes. Grew, in his Book of Rarities, gives the history of a bee supposed to belong to this genus, from the similar nature of the cells, which he says are admirably placed for warmth and safety, &c., lengthways one after another, in the middle of the pith of an old elder branch, with a thin boundary betwixt each bag ; whilst Willoughby seems to have noticed their nests in similar situations to those which we have found, namely, in sand banks ; where he says they burrow, making holes like worm holes. COLLINSIA (Nuttal). A genus of handsome annuals, natives of America. Linnaaan class and order Didynamia Angiospcrmia, and natural order Scrophularintz. Generic character : calyx bell-shaped, five-cleft, persisting ; corolla personate, back of the tube gibbous; upper lip erect and cleft, the lower one trifid, the middle division forming a hollow keel ; stamens bent downwards, in the hollow of the corolla ; anthers placed parallel ; style two-lobed ; capsule two-celled, four-seeded, and four-valved. These are elegant plants, and if seeds are procured may be treated like hardy annuals. If sown in the autumn, hey will flower early and ripen seeds in the following ummer. COLLINSONIA (Linnaeus). A genus of tall growing herbaceous plants, belonging to Diandria Monogynia, and to the natural order Labiate. Being lardy, they grow in any common garden soil, affect- ng a moist situation, and are increased by dividing he root. COLOCASIA. The specific name of a large Igyptian arum, cultivated in that country for its uberous roots. It is common in our hothouses as an rnamental plant, the leaves being large and hand- ome. COLOUR is one of the external characters, by which all objects, whether animate or inanimate, may >e distinguished; therefore in every department of atural history, it is an important element in classifi- ation and description. In zoology the species and varieties of many animals re principally determined by the colour or colours vhich they exhibit ; in botany, notwithstanding the nfluence of climate, change of seasons, soil, situation, and other incidental circumstances, every species of COLOUR. 81 plant has naturally determinate colours, by which it may be recognised ; and in mineralogy, each species of mineral presents a particular colour or suite of colours, by which it may also be identified. In meteorology, the aerial tints, the meteors, and the atmospherical phenomena peculiar to certain coun- tries, can only be appreciated by a correct perception of the different colours which characterise their ap- pearance ; while in hydrography, a similar power of discrimination is necessary, to describe the varieties of colour which occur in the seas, lakes, and rivers, which adorn while they fertilise the surface of the earth. Hence every naturalist should be well ac- quainted with the philosophy of colours; he should be able to discriminate them accurately ; he should know the effects which their several combinations will produce ; and should understand the circum- stances by which they may be modified or entirely changed. The colour of all natural bodies, whether we con- template the gorgeous hues of sunrise or sunset, the iridescent plumage of a bird, or the tints that varie- gate the petals of a flower, must be derived either from the light of the sun, or else be inherent, like any other property of matter, in the substance of the bodies themselves, the light in that case being only the passive medium through which their effect is communicated. The majority of philosophers concur in ascribing their origin to some change in the con- stitution or condition of light, yet their opinion concerning the manner in which this change takes place, must depend entirely on the views they enter- tain concerning the nature and properties of light. On this subject two theories are at present very ably maintained by their respective advocates ; the one termed the Newtonian or molecular; the other the undulatory theory of light; each of which is signally ingenious and beautiful in detail, ancP alike supported by men of the profoundest mathematical skill. According to the Newtonian or molecular doctrine, light is presumed to consist of an infinite number of very minute particles of matter, which proceed in a continuous stream from the sun, or any other luminous body, and which, impinging on the nervous filaments of the retina, with such rapidity, as to allow of no sensible intermission of the impression they excite, induce the sense of vision. On the other hand, according to the undnlatory hypothesis, light is supposed to consist simply in the undulations of an exquisitely subtile and elastic medium or ether, which pervades the whole universe. The waves of this medium, according to the impulse communicated to them by the action of what are called luminous bodies, reach the nerves of the eye and excite the sensation of sight, in the same manner as the sensation of sound is excited in the nerves of the ear by the vibra- tions of air. In the history of science, never perhaps were two theories proposed to explain the same pheno- mena, in which the evidence in favour of each appears to be so fairly balanced ; yet to understand how either may be applied to explain the origin of colours, we must revert to certain properties of light which are immediately connected with this interesting investi- gation. Whether the molecular or undulatory theory be adopted, light is observed to move in straight fines, until intercepted in its progress by passing from a medium of one density into a medium of another density; or until interrupted by impinging against NAT. HIST. — VOL. II. some semi-transparent or opaque body. In passing1 from air into water, the rays of light on entering the fluid are observed to deviate from their previous rec- tilinear direction ; they appear to become bent, and this deviation from the straight line is called the refraction of light. Hence when an oar is immersed in water, it appears distorted on account of the rays of light by which it is seen being refracted or bent, on emerging from the water. The extent, however, to which the light deviates from the rectilinear direc- tion varies in different media ; thus, as the atmosphere which surrounds the earth, is denser in its lower than in its upper regions, the light of the sun, in passing from the rarer into the denser strata, becomes more and more bent or refracted ; so that it descends to us in a vertical curved line, for which reason the moon and stars appear to us at a greater altitude than they really are; for which, in astronomical and trigonometrical observations, allowance is always made. The rays of light, however, are not refracted if they fall perpendicularly on the denser medium ; hence the refraction becomes less as the sun ap- proaches to the zenith, and increases as it descends towards the horizon ; accordingly, in the blaze of noon the sun's rays are reflected with silvery and dazzling whiteness from the surface of the waters, w-hereas towards evening, as the sun gradually sets its rays, falling obliquely upon the waters, the waves become illuminated with all the beautiful prismatic colours of the refracted light. Again, when light impinges upon any solid body, it is either almost entirely transmitted through it, in which case the body is transparent, or it is reflected or driven back at a certain angle, just as a marble after striking against a wall is reflected, or driven off again ; and this is what is termed the reflection of light. The surface of metals which are highly polished, or glass quick- silvered at the back to prevent the transmission of the rays, are the best reflectors ; as are also all white surfaces. When the earth is covered with snow, and all objects are shrouded in the same wintry gar- ment, the snowy crystals reflect the sun's light so vividly in all directions, as to excite acute pain iu the eye, an inconvenience much complained of by navigators, who have endeavoured to explore the dreary solitudes of the Polar Regions. Even the Esquimaux, and other natives of those snowy wilder- nesses, are obliged to protect their eyes from this reflection of the solar rays, by a sort of wooden shade which is commonly worn among them. To these two properties — refraction and reflection — we owe the uniform diffusion of light through the atmosphere ; indeed, had the atmosphere, instead of possessing regions of different density, consisted of an unlimited homogeneous medium, the sun, the moon, and the fixed stars, would have appeared to shine in a firma- ment of darkness ; so exquisitely adapted is the air we breathe, and the sunbeam which illumines our path, to the general economy and beauty of the universe. There is yet, however, connected with air, water, and other media through which light may be transmitted, a curious property to be noticed ; viz. when they are sufficiently dense, they absorb a great quantity of the light which enters into them ; in other words, the light which falls upon such trans- parent media, is greater than the quantity which is either refracted or reflected, so that a portion in some way or other becomes suppressed or lost. For this reason, owing to the absorption of the refracted light, F 82 COLOUR. objects become quite invisible at a certain depth below the surface of water. So also on the top of the Andes or Alps, many more stars are visible to the naked eye, than in the vallej's or plains below ; because their rays having to pass through a smaller «xtent of air, less of the light which they impart becomes absorbed. These facts are recognised, and different explanations of them proposed by the sup- porters both of the molecular and undulatory theory of light, and require to be remembered in studying the colours which different natural bodies assume. It was known to the ancients, that the light of the •SUB might be so acted upon by different objects, as to exhibit a variety of colours ; thus Aristotle ascribed the appearance of the rainbow to the reflection of the sun's rays on the falling drops of rain ; and Seneca states, that if the sun shine through a triangular piece •of glass, the colours of the rainbow will be displayed. Indeed the exhibition of colours by the prism had often been made previous to the time of Sir Isaac Newton; it remained, however, for that illustrious philosopher to examine the phenomena more criti- cally, and deduce from his analysis, more definite and important inferences than had been previously at- tempted. His method of proceeding was simple, and may be readily understood. In the first place he darkened a room, admitting through a hole in the window-shutter only a small quantity of light, which was reflected upon the opposite wall. He then, taking the triangular piece of glass or prism, inter- posed it in the course of the sunbeam, and observed, that instead of being simply directed out of its course, and forming the same circular image which it had previously done upon the wall, an oblong image of the sun appeared, presenting seven different colours. This surprised him, and he states that it " excited in him a more than ordinary curiosity to examine from •whence it might proceed ;" accordingly, apprehensive that some unevenness in the glass or other incidental circumstance might have occasioned a deception, he repeated the experiment in a variety of ways, yet always with a similar result. He then began to think, that what appeared to be white light must in reality be composed of these seven different colours; to determine this more satisfactorily, he took another prism, and so adjusted it as to refract the light in a contrary direction, so that the primary or different coloured rays were again blended together, upon which the white light was reproduced. Hence he inferred, that what seems to be homogeneous white light, is a combination of seven different coloured rays, — red, orange, yellow, green, blue, indigo, and violet; and he then proceeded to examine these different colours separately. In so doing, he allowed each particular colour to fall on a second prism, and observed that when refracted it was not, as before, drawn into an oblong image, nor into any other colour, wherefore he concluded that each of the seven primary rays of light possessed a specific degree of refrangibility, and that there is an immutable corre- spondence between the refrangibility of each ray, and the colour it possesses. This comprehends what is meant by the different refrangibilities of the rays of light ; for it was observed that the red was less re- frangible than the orange; the orange than the yellow ; the yellow than the green ; the blue than the indigo ; and that the violet was the most refran- gible of them all. The different colours so exhibited form what is described as the solar spectrum ; but it is to be observed, that by Sir Isaac Newton's analysis no lines or boundaries between the different colours were perceptible ; the colours appearing to be shaded off by imperceptible gradations into one another, and he determined their relative proportions by the individual length or spaces they occupied. It has since been ascertained by Dr. Wollaston, aided by Fraunhofer, that when the prism is perfect, and the light admitted through a very small aperture, the spectrum received on a sheet of white paper will exhibit the prismatic colours, divided by an indefinite number of dark and sometimes black lines, which in all spectra formed by solar light, preserve the same intensity and relative positions, so that they may be esteemed fixed points for ascertaining the refractive powers of different media. It is worthy however of observation, that they differ with the species of light employed, the spectra of the moon and brighter fixed stars, exhibiting lines peculiar to themselves. Further- more, it appears that Sir Isaac Newton erred, in not observing that the relations of the coloured spaces must be considerably modified by the angular magni- tude of the sun, or luminous body, or the aperture from which his spectrum was obtained; hence his proposition, " that to the same degree of refrangibility ever belongs the same colour, and to the same colour ever belongs the same refrangibility," proves to have been incorrect. The researches of Sir David Brew- ster have indeed effected a still further analysis of the solar spectrum. Taking advantage of the property which certain coloured media have, of absorbing one or more of the primary rays, this accomplished philo- sopher has succeeded in reducing the colours of the spectrum to three, viz. red, yellow, and blue; the orange in the spectrum of Sir Isaac Newton, he found to be occasioned by the mixture of the red and yellow rays ; the green bv the mixture of the blue with the yellow rays. His investigations appeal* to have established the following facts concerning the composition of the solar spectrum. 1. White light consists of three simple colours, red, yellow, and blue, by the combinations of which all other colours may be formed. 2. The solar spectrum consists of three spectra of equal length, beginning and terminating at the same points, viz., a red spectrum, a yellow spec- trum, and a blue spectrum ; all other colours in the spectrum are compound colours, each consisting of red, blue, and yellow light, in different proportions. 3. A certain quantity of white light, incapable of being decomposed by the prism, in consequence of all its component rays having the same refrangibility, exists at every point of the spectrum, and may in some points be exhibited in an isolated state. However the number of colours in the solar spec- trum may be thus reduced, the variety of effect pro- duced by their blending with each other can scarcely be brought down to analytical computation. Hence Professor Powell observes, " That a question often asked as to the number of primary colours can only be answered with reference to the sense in which it is asked. If it be meant to apply to the number of tints distinguished in the spectrum, this will be a matter of individual judgment to different eyes. Newton distinguished seven, others four, others three, but perhaps most observers would admit that it is impossible to fix on any number, since the light ap- pears to go through every possible shade of colour between the deep red and faint violet. If we under- stand the question as applying to the number of COLOUR. 83 definite points or rays, to each of which a different refrangibility belongs, their number must be considered as infinite. The general view now given of the con- stitution of light, according to the molecular theory, will enable us to understand the explanation it assigns for the different colours observed in nature. The principle on which all bodies are supposed to derive their colour is briefly this, that the particles of which they are composed" absorb some, and reflect other of the primary and different coloured rays which enter into the composition of white light. The red petal of a rose is presumed to absorb the six other coloured rays, and reflect only the red ray; the blue flower of the harebell to absorb the six other and reflect only the blue ray ; and so on with all objects that reflect the different primary rays disco- verable in the solar spectrum. Those bodies which reflect several of such rays appear of various colours ; those which reflect them all appear white, while those which absorb them all appear black ; and the absorp- tion and reflection of the different coloured rays depends, according to the hypothesis of Sir Isaac Newton, on the magnitude of the particles of which the body is composed. Thus the azure colour of the sky is caused by the particles being very small ; the green colour of vegetables depends on their being somewhat larger ; " the green of vegetables," says Pemberton, one of the most perspicuous of Newton's commentators, " our author judges to be of the third order, partly from the changes they suffer when they wither, turning at first into a greenish or more perfect yellow, and afterwards some of them into an orange or red, which changes seem to be effected by their tinging particles growing denser by the exhalation of their moisture." The change of colour, therefore, which any plant, mineral, or other substance, may undergo, either from the action of light, heat,, or vital or chemical changes, is presumed to depend on some alteration which takes place in the size of its compo- nent particles, which causes other of the primary rays to be reflected. Instead, however, of the mere size of the particles determining the inflection of one or more of the coloured rays, Sir David Brewster supposes that the particles of bodies, solid, fluid, or aeriform, have a specific attraction for the particles of light ; if they exercise a simultaneous and proportional action over all the simple rays, then the body is colourless or transparent ; if they exercise a specific attraction only over some of the simple rays, then the body exhibits a determinate colour from the reflection of the other rays, whether blue, yellow, or red. The colours pro- duced by the refraction and reflection of these primary rays are especially observable in the rainbow, in solar or lunar halos, in the glaciers that, crown the summits of the mountains in Switzerland, and at sunrise or sunset upon the surface of the ocean. Hence too the colour of the sky, the blue and violet rays being most refrangible are more copiously distributed through the atmosphere than the other rays, while the red rays being the least refrangible are not so frequently transmitted ; on account, indeed, of their diminished refrangibility, the most favourable con- dition of the atmosphere for their refraction is obvi- ously when the least vapour or moisture is suspended in it, and accordingly it is a popular observation that a red sky at sunset is a sign of fine weather the next day. In accordance too with what has been noticed concerning the disposition of certain media to absorb light, the air or vapours suspended in it are observed often to absorb the red rays ; hence the fiery aspect of the sky at sunrise or sunset, and the flame-coloured masses of clouds which are often seen dispersed even to the zenith. But this is not all, for, independent of the colours of natural bodies thus arising Irom the absorption and reflection of the primary rays, Sir Isaac Newton referred the colours of the feathers of birds, the wings of insects, the scales of fishes, &c., to the same cause as the colours exhibited by thin plates. It was ascertained by Boyle, and afterwards by Dr. Hooke, that when substances which appear to be opaque are reduced into very thin layers they display the most beautiful colours. This may be familiarly exemplified by the bubbles of the essential oils, spirit of wine, tur- pentine, or soap and water, which, as they become gradually thin, exhibit the most varied and brilliant tints. So also is it with solid substances. Glass may be blown so thin, or mica split into such fine films, as to display the same lively colours ; and on the same principle, the delicate filaments of a feather, the exquisitely fine membrane of an insect's wing, or very thin scales, exhibit similar radiant hues. The colours, however, of the plates vary according as the rays of light fall upon them ; when viewed obliquely, they are not the same as when viewed direct, for which reason the colours in the peacock's tail change as the bird changes the posture of its tail in respect to sight. Hence also the delicate plumage of the little humming bird displays the most exquisitely varied rainbow hues, so that when numbers of them are seen together flitting about a flower, or wantonly describing eccentric gyrations in the sunny air, the perpetual shifting of the colours, as the position of the bird varies, has a most dazzling and brilliant effect. The beautiful colours in the interior of shells are referrible to the same cause, as are also the colours of mother-of-pearl, which, when examined under a powerful microscope, presents a surface covered with minute stria? and parallel waving lines. The explanation of this phenomenon, given by Sir Isaac Newton, was this, that a portion of light is reflected from the upper surface of the thin plate, whether of glass or any other substance ; and that the coloured rays are refracted from the adjacent under surface. According, however, to the modern theory, which ascribes the effect to the doctrine of interference, the light reflected from the second surface of the plate interferes with the light reflected from the first, and as these two pencils of light come from different points of space, they must reach the eye with different lengths of paths ; and the resulting tint arises from the combination of the pencils. The Newtonian molecular theory of light, therefore, refers the origin of colours, first, to the decomposition of white light, and the absorption of some, and refrac- tion and reflection of one or more of the primary or different coloured simple rays ; second, to the inter- ference of light by very thin plates or fringes, the light in both cases consisting of subtle material particles emitted by luminous bodies. According to the undulatory theory of light, a very different explanation is given concerning the origin and nature of colours ; yet before stating the doctrine it inculcates, we may observe that all the properties and phenomena of light above referred to, its refrac- tion, reflection, and absorption, are upon the undu- latory hypothesis satisfactorily explained. As the undulations of the ether are propagated in a rectilinear F2 84 COLOUR. direction, on reaching a solid body, part of the undula- tions must proceed forward into the interstices of the body, and part, as from a new centre of motion, are transmitted back into the air; in the former case they are refracted, and the amount of refraction depends entirely on the diminished velocity of the propagation of the undulations within the refracting medium ; in the latter they are reflected ; furthermore, when light is absorbed, the ethereal waves are presumed to be broken and scattered in dispersed undulations through the interior of the body (Herschel) ; hence the ordi- nary properties of light may by either theory be explained ; there are, however, certain phenomena, or appearances which light may be brought to exhibit, which are explicable only upon the undulatory theory, one in particular already adverted to is what is termed the interference of light, It was shown by Arago and Fresnel, that when two diverging beams are made to cross at a very small angle, instead of giving rise to a double illumination at the point where they mix, they exhibit a space striped with alternate black and bright bands. Here, therefore, we have the paradoxical result of two con- spiring rays of light, producing absolute darkness, which is inexplicable by the molecular or Newtonian theory ; but which is a direct consequence of the theory of undulations, according to which it is obvious that when two waves, propagated from different origins, meet in such a manner that the hollow of the one coincides with the elevation of the other, and the elevation of the one with the hollow of the other, the two waves must obliterate or destroy one another. Accordingly, the point remaining at rest, where the antagonism occurs must appear dark, the agitation of the ethereal medium being necessary to affect our visual organs with the sense of light and colour. Upon this interference of light the beautiful phenomena of pe- riodical colours, or those exhibited by thin plates, appear also to be dependent. In this case a new divergence is given to some of the waves, while others pass on unaltered. According, therefore, to the undulatory theory, colour is an effect produced by the vibrations of the ethereal medium, which affects us when in undulation with the sense of light, and the difference of the colours so produced depends on the greater or lesser frequency of the vibrations, the whole scale of colours from violet to crimson lying between vibrations which are four hundred and fifty-eight million millions, and seven hundred and twenty-seven million millions in a second ; a proportion it may be observed smaller than the ratio of undulations which takes place in the production of perceptible sounds. As in sound the pitch or note is determined by the frequency of the aerial pulses, so according to the undulatory theory the colour is determined by the frequency of the ethereal pulses. 1. WHIT*. 1.

Purplish white (snow white, with the slightest tinge of crimson red and Berlin blue, and a very minute portion Whichever of these theories be adopted, the natu- ralist should acquire the power of discriminating with accuracy the distinction between every variety of colour, however blended, otherwise his descriptions, whether of animals, vegetables, or minerals, will be imperfect. It is true, that the majority of mankind readily distinguish the more obvious colours, red, yellow, blue ; but the combinations these may assume are so numerous, and the tints so delicate, that they cannot be adequately appreciated excepting by a practised eye. Hence an artist will perceive beauties in a landscape which escape the notice of an ordinary observer. It is desirable therefore that the naturalist should commence his studies by learning to distin- guish accurately the different colours of natural bodies ; he should apply to each of these a definite and correct term, expressing even the very shade it may present ; and he should know how the simple and elementary colours may be so combined as to produce the suc- cession of tints observable in shells and minerals, in the plumage of birds, the petals of flowers, and which bathe with beauty at sunrise or sunset the earth, the ocean, and the heavens. He will find that the colours which adorn the face of nature pass in suites into one another ; nor can any thing be more exquisite than the effect produced by their blending together in mutual harmony. The eminent Werner directed his attention to forming a nomenclature of colour, which has been adopted by Professor Jamieson, and adapted to the study of botany, zoology, and meteorology, bv Mr. Syme. The original suite of colours was by- Werner fixed at seventy-nine ; but finding the num- ber defective when applied in the study of zoology and botany, it was extended by Mr. Syme to a hundred and ten. " The method of classification adopted by Werner was," says Professor Jamieson, " simple and elegant. He placed together all those varieties which contained the same principal colours in a preponderating quan- tity, and he then arranged them in such a manner that the transition of the one variety into the other, and of the principal into the neighbouring colours was preserved, so that by mere ocular inspection any person, accustomed to discriminate colours correctly, can analyse the different varieties of colour which occur in the mineral kingdom." In this system as improved by Syme, there are ten principal colours, each of which contains one that is called the charac- teristic colour ; thus snow is the characteristic colour of white, velvet-black of black, Berlin-blue of blue, emerald-green of green, &c., and this characteristic colour is so placed in the scale that, ascending or descending from it, we may trace the colours which are connected by transition. The following is the mproved nomenclature of the Wernerian system by Syme ; it explains how the gradations of colour are produced, and illustrates them individually by refer- snce to some animal, vegetable, or mineral *. of ash grey).

The colours which may be thus recognised in the animal, vegetable, and mineral kingdoms, are liable to undergo many changes which appear determined by the influence of light, heat, change of seasons, climate, age, food, soil, and certain chemical actions to which all inert matter is constantly liable. It appears to be a provisionary law that animals, sub- jected to be preyed upon by other animals, assume the colour of the soil or medium by which they are surrounded. Thus rabbits appear of the colour of the soil in which they burrow, arid the colours of the scales of fish vary according to the colour of the river beds over which they swim. It has been shown by an intelligent naturalist that when perch, gudgeon, or minnows, are confined in water, the bottom of which rests upon different coloured soils, the scales of the fish gradually change their colour, and assimilate to that of the soil (Stark, in Jamieson's Journal, vol. ix. p. 329, 1830). A still more remarkable exemplifica- tion of this provisionary law may be observed in the colour of the eggs of birds. Those birds whose nests and eggs are more exposed to the view of their ene- mies than other animals, lay eggs which are of the colour of the objects by which they are surrounded ; thus the partridge, pheasant, and other birds which lay their eggs among grass without any regular nest, present us with eggs of a greenish colour, so that they escape the detection of rapacious birds ; while those which nestle in holes, as the woodpeckers' wrynecks, water ousels, and swifts, present us with eggs of a pure white, which, if exposed, would be immedi- ately perceived by their enemies (Ibid, vol. viii. p. 130, 1829). The most curious fact, however, which the naturalist observes is the change of colour which plants and animals, under various circumstances, undergo. These too are often of singular contrast ; thus the flower of the blue crocus frequently changes into yellow, the blue columbine to red, the blue violet to white. The changes too during inflorescence are often very remarkable ; thus the flower-buds of the scorpion grass (Myosotis palustris] are delicate rose colour, but they turn to a bright blue as they open. It is well known that the plumage of birds, and the hair of quadrupeds, are subject to remarkable changes of colour, determined obviously by the influence of season, climate, age, food, and other incidental cir- cumstances. As winter approaches, the ptarmigan begins to change colour, and gradually, about the month of February, becomes perfectly white. As the summer, however, returns, black spots appear upon the feathers, which gradually expand into a reddish brown until, in summer, the bird resumes its mottled brownish colour. The change of the human hair from a dark colour to grey or white is a matter of daily obser- vation, and known to be caused by grief, and also by old age. The hair of the unfortunate Louis XVI. of France became quite grey during the night previous to his execution ; so also, on the authority of Madame de Campan, did that of the unfortunate Marie Antoinette the night previous to her unhappy death. And to what are these changes of colour referrible ? the explanation will depend entirely on the theory of CO LTS'-FOOT— COLUBER. /»lour adopted. If we accept the Newtonian o molecular theory, we must conclude that some change takes place in the size of the particles of the bodies whether hair, feathers, or flower petals, which causes an alteration in the absorption and transmission o the primary rays ; thus in the case of the autumna leaf, when no longer nourished by the usual circula tion of the sap, its particles undergo a change which cause it to absorb the green rays which were before reflected, and reflect the red, orange, or red rays which were before absorbed. To this theory, how- ever, Sir David Brewster does not assent ; he con- siders it probable that these tints are caused by two different juices on each side the plant, which exert a different affinity over the primary rays. " The colours of vegetable life," he observes, "and those of various kinds of solids, arise, we are persuaded, from a specific attraction which the particles of these bodies exercise over the different coloured rays of light." As au- tumn therefore advances, we are to presume that the juices of the leaf change; there is a difference in the secretion, and consequently in the attraction of the primary rays. It must, however, be confessed that this is a mere hypothesis, it is overturning one theory by another equally undemonstrable, for where is the proof that any such affinity exists as is here supposed ? Lastly, if we adopt the undulatory theory, we must conclude that the change of seasons, age, climate, &c. causes such a change in the particles of bodies as induces a greater or lesser frequency in the undulations of the etherial medium, now producing the violet and now the crimson colour. However veiled in obscurity may be the laws of light and colour, the different colours which irradiate the world, are of eminent importance in the general economy of nature. The colour of different soils influences their fertility, the darker soils absorb, and the light reflect the solar rays. The varied shades of green presented by grass, herbs, and the foliage of trees, relieves the surface of the earth from a monotony which otherwise would have been painful to the eye. The gaudy plumage of birds in tropical climates pro- tects them from the direct heat of the sun's rays, wnich are reflected from their feathers in brilliant rainbow hues. Animals, which are guided principally by the sense of sight, are attracted to their prey by the colour which now exposes and now conceals them from their view. The vulture perceives chiefly by its colour its prey at an almost incredible distance; and whales are attracted by their colour to the molluscae on which they feed. The disposition, therefore, of the colours of natural bodies is in strict unison with that harmony of design which is manifested throughout the universe, and which reveals itself, especially to the naturalist, in every path he is tempted to explore. COLT'S-FOOT is the Tussilago farfara of Lin- naeus. It is a medicinal herb, and a very troublesome weed to the farmer of damp clayey land. The flowers come forth early in the year, and long before the large roundish leaves. Deep and repeated ploughings in the spring months is the only method of destroying the roots and preventing it spreading. COLUBER, a genus of ophidian reptiles, belong- ing to the division of true serpents which are not venomous ; and exceeding in number any other genus of the order, and, indeed, every genus of reptiles. They are of course without fangs or moveable teeth adapted for inserting poison into wounds ; and, there- fore, they are either simply swallowing serpents, or crushing serpents, according to their size and strength- They have large plates on the belly, and a double row of plates on the under side of the tail, by which they are readily distinguished from the poisonous serpents ; but the number of species in the genus itself is so great, and the distinctions between some of them are so slight, that they can hardly be brought into any intelligible order without a degree of minuteness of detail, which is quite incompatible with the nature of a popular work ; and which, though it could be accom- plished, would be of little value to any but those who make this very difficult class of animals a particular study. In disposition and habits they all very nearly re- semble each other ; but they differ greatly in size, in strength, and consequently in the sort of prey on which they live. Their head is generally flattened, of an elongated oval form, having the muzzle blunt and beset with a few tubercles ; the head is covered with large plates, about nine in number. Their tongue is forked, and they move it with great celerity ; and from this probably has arisen the vulgar notion of the tongues of serpents being darts with which they can inflict envenomed wounds ; which notion, though it has found its way pretty largely into figurative writ- ing, is of course wholly without foundation. The lips of these serpents are usually covered with scales rather larger than those on the body. The teeth in the jaws are numerous, and generally much hooked, and they assist in the process of swallowing. In some of the smaller species the skin is very tender, but in the larger ones it is correspondingly strong. That of the head and throat, in particular, admits of great exten- sion ; but when the scales are removed, and it is tanned into leather, it is compact and thick, and very durable. The scales upon them all are imbricated, and generally speaking they are lozenge-shaped, and the marks of them give a very peculiar appearance to the tanned skin. The whole of the genus are oviparous, and most of them deposit their eggs in the ground to be hatched by the heat of the sun. Those eggs are elongated ovals, with the ends of equal thickness, and covered with a whitish membrane about the consistency of parchment, which is flexible at first, but which hard- ens by exposure to the air. The young, while in the egg, floats in an albuminous fluid, something similar to that which surrounds a chick in the egg ; and it is Furnished with a true umbilical cord, which is attached to the belly a little in advance of the vent. All the species of this genus are understood to change their skins as is the general habit of serpents. Both from their form, and the power and vora- city of some of the larger species, these animals lie under the general denunciation which the civilised world appears to have pronounced upon the whole serpent tribe. Whether this arises from the meta- )horical allusion to the serpent, as the symbol of temp- ation in the book of Genesis, it is of little consequence o inquire ; neither is it worth while to go into a brmal refutation of the vulgar notion that serpents walked on feet, before the catastrophe above alluded o ; and that, in consequence of their deceitful con- luct, they were subsequently doomed to crawl on heir belly. We may just remark that a serpent is no more a mutilated creature than any other member of he animal kingdom ; and that, all footless as they are, heir powers of locomotion are, especially in many members of this genus, very efficient and also very COLUBER. graceful. If we were to take the degradation of the serpent, in point of shape, in a literal sense, we would also require to take its feeding in the same. Now, the metaphorical denunciation against the serpent is, that it shall "eat dust" as well as crawl on its belly ; and we know from observation, that there is no ser- pent whatever which subsists upon this species of aliment. By far the greater majority of serpents prey upon live animals of some description or other ; and the part which they thus perform in wild nature is a very important one, especially in warm regions, where the production of small life is so abundant and so rapid, that, were it not for some such a race of beings as the serpents, the system of nature could hardly be carried on. It may not be amiss, as tending in part to remove the obloquy under which this order of animals lies, and the horror which the vulgar have in general of them, to mention very shortly the meaning of the word " ser- pent" in the passage above alluded to. It means " self conceit," or a following of one's own appetites not only without any regard to right and wrong, but with a knowledge that the gratification of the appetite is not right ; and the denunciation is directed not against any species of ophidian reptile, but against this figu- rative serpent — the corruption of the human heart, or the perverseness of human actions. " Upon thy belly shall thou go," is the declaration of what we perceive every day to be true ; namely, that they who once break through the laws of justness and propriety in the gratification of their bodily appetites, lose their intellectual character, and become the slaves of their own animal propensities, for the whole of which the belly is often used as a figurative and certainly a very appropriate expression. So also the eating of dust means nothing more than that those who thus degrade their intellectual nature, and become mere animals in habit, can have no possession, and no feeling of the value of any possession, except what is connected with gross material indulgences, the figurative name for which, is very often the dust of the ground ; and this dust, in the sense in which it is thus used, is a very appropriate name — it means vegetable mould, or that species of earth which is most favourable to the growth of plants ; and we need not add that this mould is the primary element in the support both of animals and of vegetables, the only substances which can gratify the appetites of man. These remarks are not foreign to the subject in hand, because the genus coluber contains those ser- pents which are more generally distributed over the world, most numerous, most beautiful in their colours, and most disposed to remain near the habitations of man, and we may almost say absolutely court human society. Though they belong to different classes of animals, differ much in their forms, in their mode of production, and in their way of life, yet, if we take those differences along with us, we shall find that there is a considerable analogy between those serpents and the cats. They inhabit different kinds of places no doubt ; and, generally speaking, they are better swimmers, and much more aquatic in their habits than the feline race, but they resemble these in the facility with which they glide through tangled places, and the certainty with which they capture small quadrupeds, birds, and other little animals, especially different kinds of mollusca, which would not leave a single green leaf in the more humid brakes of the warm latitudes, if it were not for the labours of these ser- pents. Those places are very generally so close and tangled, that nothing but a serpent can penetrate them ; and thus, though there are many large birds which ply diligently as scavengers in the tropical countries, they can only prey in places which are comparatively open ; and thus, though they might and do pick up the dead bodies of those small ani- mals, which are subject to casualties during the vio- lence of the season, and also catch a good number of strays, they leave what may be considered as the nurseries of small animals wholly untouched ; and thus the serpents become the true regulators of their numbers. When we compare the species of this genus with each other, and take along with them the boas, which though they have distinctive characters in the systems of natural history yet very much resemble the colu- bers in their habits, we find that though there is not, strictly speaking, a polar race, as there is in the cat tribe, yet there is, as in these, an increase, both in numbers and in size and strength, as we approach those regions of the world where the action of life, both animal and vegetable, is at a maximum. A very little reflection will suffice to convince the reader that there can be no species of serpent well adapted for inhabiting the land in the extremes of the polar countries. Serpents are covered with scales, which, even admitting that they are composed of the same materials as fur or feathers, are, from the very fact of their being in solid plates, while the others are loose and flocculent, much better conductors of heat. The consequence is, that serpents are capable of en- during only a limited range of temperature, in which respect they bear no inconsiderable resemblance to scaly fishes, and no attempted domestication would probably succeed in enabling a serpent to accommo- date itself to difference of climates, or of seasons, to any extent at all comparable with that of which furred and feathered animals are capable ; neither would it, perhaps, be possible to preserve them in a state of activity during those seasons of the year at which they are naturally dormant. We shall, however, be better able to notice those physiological characters of ser- pents which adapt them to different latitudes, and to peculiar localities, when we have the whole class be- fore us in the general article OPHIDIA ; therefore we shall only farther remark that in the north-west of Europe, the species of coluber are very rare, that they increase as we proceed southward and eastward, and probably extend farther into Siberia than they do in- to corresponding climates into western Europe. In those northerly places, however, the individuals are of small size ; but in the Oriental Archipelago, they rival if they do not exceed the Boas of the American continent ; and, though many of the stories told of them must be considered as exaggerated, yet it is cer- tain that in Java, and the adjacent islands, they are very formidable animals capable of crushing deer and goats to death in their folds, and of swallowing an animal several times the diameter of their own body. All the members of the genus are, indeed, remark- able for their capacity in swallowing. Their jaws, of which nearly a corresponding description will be found in the article BOA, are capable not only of opening till the whole gape is a plane, but of considerably more distension both ways, by means of the elastic cartilage which unites the different bones of the jaws. The smaller species subsist upon frogs, small lizards, mollusca, mice, and other little animals. And in COLUBER. situations where they abound, and are not destroyed in consequence of the superstitious prejudice there is against them, they are useful in clearing the vicinities of houses of many troublesome creatures. They are also generally expert in climbing trees, and almost all of them are excellent swimmers. They are not abso- lutely aquatic, but they prefer moist situations ; and the very large ones are seldom found at a great dis- tance from the water. There are some idle stories believed by the coun- try people of those places where serpents of this genus are common, such as that they suck the milk of cows, whose mammae they reach by twiningup theirhindlegs, and that by holding on with their teeth while they suck, they occasion disagreeable wounds. Jt does not, how- ever, appear that there is any truth in these stories, any more than there is in the other allegations, that they are apt to creep into the mouths of persons who sleep in the open air near their haunts, and if they do not choke them by sticking in the throat, prove very disagreeable inmates of the stomach. This prejudice is a very old one, and we find it continued to the pre- sent day; and it has not always been confined to the mere vulgar, but was eagerly laid hold of by empirical practitioners in pretended medicine, during those periods of the history of that most extraordinary art, when it was not deemed necessary that the doings of the doctor should have any connexion whatever with physiology or with common sense, but that he had the better chance of success the more he was opposed to both. That these animals are fond of creeping into holes is certainly true ; but the mouth of a warm-blooded living animal is not the most likely lodging-place for them ; first, because the temperature would be too high for them ; and, secondly, because the gullet of an animal is the gate of death to everything which enters ; and if it were possible to imagine that a savage could once get a tiger or a boa constrictor fairly down his throat, indigestion apart, he would feel no more trouble from it than from any dead substance. There neither is nor can be any living creature in the sto- mach of an animal, but such as can naturally breed there ; and of parasitical animals (Entozoa) which are found in the alimentary vessels of other animals, the majority, if not the whole are found in the intestinal canal farther down than the true digestive stomach. In temperate countries none of the colubers attain a very large size ; but they are often very beautiful in their colours, and very lively and graceful in their motions. The sound of all their voices is a sort of hiss, sometimes very sharp, but varying considerably in tone in the different species. When the weather begins to get cold, they retire to their holes, where they remain dormant till the spring ; and they are not much seen abroad even in the warmer months. In the warmer part of the season, indeed, they seem to re- quire a good deal of exposure to the sun before they recover from their torpor ; for then they are abroad and active in proportion as the weather is hot and sunny ; but it should seem that, beyond a certain de- gree, the heat of the sun is not so favourable to them. This must, however, in no small degree, depend upon the nature of the climate, and the consequent adapta- tion of the species. The number of species, and even of sub-genera, into which these reptiles have been divided, are so many, and have been so differently arranged by dif- ferent authors, that the details of them would 'convey no popular information. The simplest view that can be given of them is a division into four sub-genera : Python, Hurria,JDipsas and Coluber, properly so called, and it is the last of the sub-genera of which the species are so numerous, and many of which are natives of temperate climates. PYTHON. This sub-genus very closely resembles the boa, except that the plates on the under-side of the tail are double, whereas those in the true boas are single. The largest species of this genus is the great coluber of the Sunda Isles (Coluber Javanicm], which is called " Ular sawa, or the water serpent," by the Malays. It does not appear, however, to be exclu- sively an inhabitant of the waters, though it is gener- ally found near the rivers, or in marshy or humid places. It is a large species, sometimes attaining the length of thirty feet ; it kills its prey by crushing, and is the boa constrictor of the eastern world. There are one or two other species of this sub-genus, named by systematic writers, and both described as being much smaller than this one ; but it does not appear that, unless in so far as size and strength are concerned, they differ much in their manners ; and, from the long life, slow growth, and annual change of skin, and many other circumstances, together with our general igno- rance of the habits of the more powerful serpents, it is no very easy matter to say what is a species, and what is not. HUKRIA. This sub-genus is altogether doubtful, being probably founded upon an imperfectly formed species of the other; and its specific distinction, which is that of having the scales at the root of the tail single as in the boas, but those toward the point double as in the colubers, is not of much importance. DIPSAS. This name, which is given to an Indian serpent, which is black marked with white rings, is not a very happy one, in as much as dipsas was the Greek name for a fabulous serpent (or one that we may presume to have been fabulous), the bite of which occasioned death by thirst in the person bitten. This species, which is quite harmless, has been confounded with a species of viper of the same country, which is poisonous. The body of this serpent is compressed, not so thick as the head ; and the scales along the back are larger than those on the sides, and form a sort of elevated crest. COLUBER. Of this sub-genus there are about 147 species mentioned by the systematic writers on Ophio- logy (or the natural history of serpents considered as a class), and many more are named and probably exist, at the same time it is not impossible that two or three names may, owing to accidental differences of appear- ance, have been given to the same species. The his- tory of so many species, none of which differ very murff in their manners, could hardly be treated in a popular manner, even if the particulars were all well known. But that is far from being the case ; so that we must content ourselves with brief notices of a few, both of the European species and of those which are met with in other parts of the world. Common Snake (Coluber natrix, Natrix torquata), this is the most generally distributed, and on that ac- count the best known, of all the European species. — It is also the only one, or at least the principal one, which is found in Britain, not unfrequently in England, but much more rarely in Scotland. It grows to the length of three or four feet : its back is of a dusky- brown colour, with two stripes formed of a succession of black spots, running the whole of its length ; and COLUBER. 91 these are crossed by irregular spots of the same colour which are very numerous. The belly is dusky with a tinge of blue ; and there is a spot of yellow, with a three-cornered one on each side of the neck. These last-mentioned spots compose the collar, from which the species gets the name of torquata, or ringed. The head is flattened, and the muzzle rounded ; and the head has four rows of large scales, two in the first row, two in the second, three in the third, and four in the fourth. There are seventeen scales in each jaw : the scales on the sides are very small and smooth, without any keel or projection in the middle. There are about 120 plates on the belly, and from fifty to sixty pairs on the under part of the tail. The eggs, which are about eighteen or twenty in number, are deposited in dunghills, hotbeds, and other places where they have the advantage of heat from the fermenta- tion of vegetable or animal matter. This species is chiefly found in humid places, near the margins of waters, and it takes readily to the water, and is rather an expert swimmer. Its food consists of mice, frogs, insects, and molluscous ani- mals. It is a harmless and even gentle creature, and capable of being tamed, in which state it shows not a little attachment and affection ; and gives evidence that it was intended for some useful domestic purpose , for it is a law, and a very beautiful one, in the animal king- dom, that every animal, of whatever race it may be, and whether an inhabitant of the land or the water, which courts the society of man, or even shows no positive reluctance and desire to escape, is in some i way or other useful to man, or might be rendered so, if man would study its nature, and attend to the func- tions which it is capable of performing. But the harmless nature, and the gentle manners, and even the 'Usefulness of this animal, have not been sufficient to iprotect it from a full share of that very unfounded prejudice which people generally have against the whole of the race. Even the Bard of Avon, who is, generally speaking, as superior as a naturalist as he is is a poet, has helped to perpetuate the animosity with which this gentle creature is attacked. This is the ;'' water" or "ten" snake, which formed one of the ingredients of the "cauldron of diablerie," prepared ,Dy the witches, in order to shake the soul of the »tern Macbeth, and torment him before his time : Fillet of a fenny snake. In the cauldron boil and bake. This species of serpent is delicate in its nature, and ! lot found in the colder or more elevated parts of the •Country. In Scotland, it is very rare, and confined .0 some of the warmer districts of the south ; and ilthough there is a Scotch name for it, there is not a 3aelic one, so that it never can have been common, t>r even known in the Highlands of Scotland, where here is a name for the poisonous viper. But although t has not been found in the eastern parts of the riighlands, there is some reason to believe that it is ty no means rare in Argyleshire, and in some of the nore southerly of the Hebrides, where the climate is nild and humid. It is also said to be rather common a many parts of Ayrshire, near the coast, especially bout the hills of Dundonald. But as, in Scotland specially, where snakes of any kind are of rare occur- ence, and in many places of which, the people will ot eat eels because of their snake-like form, every one hat can be discovered is instantly killed, and killed •ith the stigma attached to it that it is a poisonous viper, or adder, as it is called in that part of the island. One specimen, differing in its characters from the common species, is mentioned as having been dis- covered in the south of Scotland, near Dumfries, the plates on the belly of which are stated at 162, and those on the tail eighty. The colours were at the same time paler than those of the common snake, and the dorsal scales without any mesial crest as they have in that species. But the specimen was a very small one, not above five inches in length, and no mention is made of any other instance of its occur- rence within the island ; so that it is impossible to form any positive conclusion respecting it. The hisr tory of British reptiles is a subject which stands in need of far more extensive and more careful investi- gation than it has hitherto met with ; but from the peculiar haunts, the retiring habits, and the long hybernations of most of these animals, the study of them is attended with peculiar difficulties. Coluber coronella. This species is not uncommon in the northern parts of France, and seems to resemble the Dumfries-shire specimen rather more than the Austrian snake does, with which Dr. Fleming, in his account of British animals seems disposed to class it. This one is represented as being of small size, and with all its scales perfectly smooth ; the upper part of the body bluish, with two rows of lenticular black spots ; the flanks are of a pale reddish colour, clouded in some places with darker ; and there are two triangular spots of yellow at the back of the head, which is of an oval form, and covered with very large scales for the size of the animal. Coluber viridiflavus. The green and yellow snake is a very beautiful species, very abundant in the south of France, and especially in the country around Bor- deaux. The size varies from two to five feet in length ; its head is large, its under part is of a delicate lemon yellow, and the scales on the upper part are alternately intense black and very brilliant green, variously marked in different specimens, but always very rich and beautiful. The tail is longitudinafiy marked with black and yellow. This species is very expert in climbing trees, and in capturing small birds, and plundering their nests ; it is a very delicate crea- ture, and killed by the slightest blow on the back. Coluber Austriaca. Though this species was first discovered ia Austria, and named after that country, it is, perhaps, more abundant in the south of France, in Spain, and in some parts of Italy, than it is any where to the northward of the Alps. The upper part has the ground colour of a reddish grey, marked with five small lines behind the eyes, a bar across the back of the head, and two rows of alternating spots along the back, which are brown and blackish. The lower part is iron grey, clouded with darker. Its scales are entirely smooth, and the upper part has a shining lustre. It is but a small species. Coluber viper'mm. This species is found in the south of France, in Spain, and in Italy. It is of a brownish-grey colour above, marked with a zig-zag line of spots down the back, which are yellow in the centre, and black at the extremities ; there is also a row of very small spots along each side. The under part is mottled with black and grey. Coluber tclragonus. This species, as its name indicates, has the section of the body of a quadran- gular form. It is small, rarely attaining a foot m length, and is not so common as many of the other COL UM BELL A. species, though it is met with in some parts of France. It is a shining serpent, with smooth scales, greenish grey on the upper part, with a row of black dots along the dorsal line, and two parallel ones on the sides. The lower part is yellowish. Coluber quadrilineatus, the four-striped snake. The Coluber elaphis of Shaw is the largest of all the Euro- pean serpents, and is generally understood to be the boa of the ancients. It is yellow on the upper part, marked with four longitudinal lines of brown, or black, and this part of the body has a soft velvety appearance ; the under part is black, and glistens with a lustre resembling polished steel. The scales on the back are carinated, but those on the flanks are smooth. Coluber flavescens. This is the Esculapian ser- pent, Coluber Esculapii of Shaw, but not the Escu- lapian serpent of Linnaeus. The species to which he gave that name is a native of America, and of course could not by any possibility be known to the ancient Greeks. This species is very common in Greece, in Italy, and not rare in some parts of France. It is thicker in proportion to its length than any of the European species, and its hiss is much stronger and louder. It is an active animal, and preys equally on the land and in the water, gorging itself while success- ful, until it is unable to move. Jacquin mentions one that was killed while in the state of semi-dormance, in the stomach of which there were five small birds, a common lizard, and a mullet, which, substituting turtle for lizard, formed three courses worthy of an alder- man ; and in procuring which we must naturally sup- pose that this rapacious serpent had laid the air, the earth, and the waters, under contribution within a very short space of time. The colour of the upper part is of an earthen grey, with a longitudinal band of a darker shade on each side ; the scales nearest the abdominal plates are white, with black borders on their under edges. The belly is whitish mottled with grey. Coluber meridionalis. This species is found in Provence and the adjoining parts of the South of France. The ground colour above is greyish, with large ash coloured spots on the top of the head behind the eyes, and with four lines of smaller ones along the sides. The spots on the back run into each other two and two ; but those on the sides are all separate. The extremity of the transverse plates is black, the middle white, marked with black spots. This is a very small species, and not so common as some of the others. Coluber Girondicus is greyish, with smooth scales, the sides of which form brown bars across ; the belly is damasked with yellow and black ; the head is compressed, and there is a cross mark on the top of the head. This species has been observed on the banks of the Gironde, where it attains rather more than two feet in length. Coluber sanguinolenta. This species has also been observed on the banks of the Gironde. It bears some resemblance to the Esculapian serpent, but it is smaller, and its colours are differently marked. It is brownish ash, mottled with round spots of reddish brown with black centres, which give it the appear- ance of being spotted all over with blood, hence its specific name. Its scales are carinated, and its head is large and broad. The preceding list is considerable, and yet we have no reason to suppose that it includes more than a fraction of even the European species, of this very extensive genus. In various places of the South, ana even in the central parts of the country, colubers arc mentioned, differing much both in their forms and their markings, from any of those which we have noticed ; but the accounts of them are very vague ; and so little is known of the habits of the animals, and the changes of appearance, from age, season, and sex, to which they are subject, and also of the varie- ties, climatal or otherwise, into which they are apt to run, that we must speak of them with great caution and shall only farther observe of this genus, as European, that it offers a very wide, and far from an uninteresting field of inquiry, to those who are fond of natural history, and who have the means of scruti- nising with due attention those wild and semi-aquatic placest|in which members of the genus are most likely to be found. In other parts of the world the species are still more numerous than they are in Europe, and some of them attain a larger size. They may all, however, be considered as swallowing serpents, rather than as killing their prey by crushing it to death, though many of them have considerable strength in their folds. They are all perfectly harmless to man, and, generally speaking, of very great service to him, both in the protection of his growing crops, and his maga- zines of grain. In warm countries the depredations committed by birds, are beyond any extent of which we, of these mild latitudes, have any idea. They come, one hardly knows whence, in flocks which absolutely darken the air, and are quite sufficient to consume the whole crop on a large plantation in the course of an hour or two. In many parts of India, indeed, and in other tropical countries, one of the severest species of field labour which the people are called upon to perform, is that of protecting their crops from the birds. In such countries stages are erected by the sides of all the little cultivated patches, and the youth are kept continually on the alert, hallooing and shouting to scare away the winged plunderers, which are to a verv great extent noise proof. In those countries, at least in places where part of the land is under crop, and kept irrigated, so that there is a succession of insects from the supply of water, birds nestle and breed at all seasons ; and were it not thai there is some means of keeping down their constantly augmenting numbers, they would very speedily obtain the mastery of all nature; for we have evidence in various parts of the animal kingdom, that individual strength is of no avail whatever against combined numbers, be the indivi- duals as weak as they may. We have proof that the antelope, the buffalo, nay even the lion himself in wild nature, may be starved to death by the invasion of the locust ; and we sometimes feel in our own country, that the checking of vegetable action for a few days, and the consequent tendency to a saccha- rine state of the juices, will destroy the crop of our orchards in very brief space. Now when we consider that birds are individually much more voracious than locusts, although the latter ply a very willing tooth, yet we must admit that those means by which the excess of the smaller feathered creatures is kept down in tropical countries, is among the most beneficial to man ; and this is a labour which snakes of this genus are incessantly arid successfully performing. COLUMBELLA (Lamarck ; VOLUTA, Linnaeus). These shells were classed by Linnaeus with the genus COLUMBINE — COM BRETACE^. Valuta, from which they are, however, very distinct, having the interior part of the right lip or margin gibbous or thickened, rendering the aperture narrow and waved, and by having also a very small thin ellip- tical operculum, which latter circumstance, Sowerby observes, allies this genus to that of Ricinula. The shells of this genus are short, small, rather thick, often striated transversely, and much varied in colour ; in some respects they appear allied to the genus Mitra. There are plaits on the columbella, it is more or less notched, and without a canal. The animal is not completely known, it is of the second class Parace- phalophora, first order Siphonobranchiata, first family Siphonottamata. These shells inhabit the seas of hot countries ; about eighteen species are enumerated by Lamarck, and one fossil by De France. COLUMBINE is the Aqttilegia vulgaris of Lin- naeus. It is a native of Britain, but has a good many foreign associates. Their flowers are of very re- markable structure and bright colours, for which they have (bund their way into every flower garden. COLUMELLI ACE.E. A natural order of dico- tyledonous plants, which has been formed by Mr. Don, and which contains only a few genera as species. It is allied to Jasminea, and corresponds with that order in the structure and aestivation of its corolla, in its bilocular ovary, and in the structure and dehiscence of its capsule ; but it differs in having an adherent ovary, a perigynous disk, an undivided stigma, and an inferior capsule with many-seeded cells. The essential characters, as given by Don, are : calyx turbinate, superior, many toothed ; corolla rotate, five to eight partite, with a convolute aestivation ; stamens two ; anthers linear, one to two celled ; ovary inferior two celled, with an indefinite number of ovules ; style simple, declinate ; stigma capitate ; disk perigynous fruit, a two celled, many seeded capsule ; seeds ascending. The plants belonging to this order are shrubs, trees or herbs, with opposite entire leaves, and solitary yellow flowers. They grow in Mexico and Peru Their properties are as yet unknown. The chie genera of the order are, Columellia and Menodora. COLUMNEA (Limweus). A genus of under- shrubs and climbers, natives of the West Indies Linnaean class and order Didynamia Angiospcrmia, am natural order Scrophularince. Generic character calyx in five parts ; corolla tubular, limb erect, am two lipped ; upper lip hollow, elongated, and gibbou above the base, with acute reflexed segments on eacl side ; lower lip spreading, and entire ; stamens unde i the upper lip ; anthers two celled, and placed clos together ; fruit a two celled, many seeded, berry I These are pretty flowering plants, and easily propa I gated by cuttings struck in sand ; they are, however I easily lost if over watered or kept in a damp part o the stove. COLUTEA (Linnaeus). A genus of ornamenta ' shrubs, natives of the south of Europe. They belon to Diadclphia Dccandria, and natural order Legum \ nosee. Generic character : calyx of five teeth ; stan dard furnished with two callosities at the base ; kee obtuse ; stigma on the side and under the apex of crooked style ; pod on a footstalk, inflated, mem branaceous. This plant is called bladder-senna i English lists, and is a favourite shrubbery genus, •< they flower abundantly, and ripen seeds, by whic .j they are propagated. COL YMBETES (Clairville). An extensive genus coleopterous insects belonging to the section 'entamera subsection Adephaga, and family of the ater beetles, Dytiscidce. The species are of an inter- icdiate size, and oval form. They frequent ponds, rooks, and other standing as well as running water ; ley are found throughout the year, but are most bundant in the spring and summer months ; they wim with great agility, and may often be seen in hot reather to quit their native element and rise to a onsiderable height in the air with the assistance of leir large wings. There are upwards of thirty British pecies, including the type Dytiscus striatus, Linnaeus ; tiey are generally distinguished by having the tarsi omposed of fivejoints, the four anterior in the males are iilated into an oblong plate, the antennae are as long s the head and thorax, and the scutellum is distinct. COM ARUM (Linnaeus). A British plant found m most bogs, commonly called marsh-cinquefoil. It •elongs to Icosandria Polygynia, and to the natural )rder Rosacea. This plant was called Potentilla vmarum bv Scopoli, an Italian botanist. COMBRETACE^E, the myrobalanse family. A natural order of dicotyledonous plants, containing eigh- een genera, and upwards of one hundred species. It s allied to Myrtacea and Onagrarice, agreeing with .hose orders in the structure of the embryo and flower- It also bears a strong affinity to Santalaceae and El in which the florets of the disk or centre are hermaphrodite or perfect, and those of the ray or margin are furnished with pistils only, but all pro- ducing perfect seed. The third section is Polygamia rustranca, in which the florets of the disk are perfect, while those of the margin are neuter or destitute of pistils, as well as stamens, and the fourth section is Polygamia necessaria, in which the florets of the disk have stamens only, while those of the ray have pistils only, so that both are necessary for the production of perfect seed. Jussieu, in his natural arangement, has divided the Compositse into three sections ; I. CynarocephaletB, or the artichoke tribe, in which all the florets are NAT. HIST. — VOL. II. flosculous or tubular ; II. Cichoracca:, the succory tribe, in which the florets are all ligulate or strap- shaped ; III. Corymbiferce, the corymbiferous tube, in which the florets of the centre are tubular, while those of the circumference are ligulate. Cassini, Lessing, and Brown, have devoted parti- cular attention to this order, and have divided it into a great number of sections. As these divisions are too minute to be interesting to the general reader, we conceive that it is unnecessary to enter into any details with regard to them. In the observation's which we propose to make on the order we shall adopt Jussieu's division, which is the most simple, and the best adapted for a work like the present. Composite plants are found abundantly in all parts of the world, and are said to constitute almost one- twelfth of the known vegetable productions of our globe. In different countries, the proportion which the Composite bear to the other pha:nogamic plants varies considerably. Humboldt states that they con- stitute one-seventh of the flowering plants of France, one-eighth of those of Germany, a fifteenth of those of Lapland, a sixth of the North-American Flora, and one-half of those of America within the tropics. They form only a sixteenth part of the Flora of jNew Hoi- land, and the same proportion of the Flora of Mel- ville Island. In their relative increase and decrease, they do not appear to follow any general law of cli- mate. It may be stated generally that the Cicho- racece are chiefly found in cold, and the Corymbiferce in warm regions. The Composite are herbaceous in the colder quarters of the globe, and become shrubby as we approach the equator. If we examine attentively the plants belonging to this vast family, we shall find that they are not only naturally grouped together by their structure, but that they also agree remarkably in the medical properties with which they are endowed. They are all more or less tonic and stimulating ; they contain a bitter, extractive, milky principle, and a volatile oil which is often solid and concrete, and has a strong resem- blance to camphor. Each of the Jussieuan subdivi- sions of the family present some distinguishing pecu- liarities in their properties, and we shall therefore notice them separately. I. CYNAUOCEPHALE^E. The plants in this sub- division of the order possess intensely bitter proper- ties, owing to the presence of much extractive matter, and they act chiefly as tonics. By cultivation, how- ever, this bitterness is much lessened, and the plants in some cases become edible. The volatile oil, cha- racteristic of the family, is not very abundant in this division. Under this division are included the genera, Cynara, the artichoke and cardoon, Carduus, Cnicus, Onopordum, Carthamus, Arctium, Carlina, Ccntaurea, &c. Cynara Cardunculus, common cardoon, was origi- nally a native of the south of Europe and north of Africa, but is now found in various parts of the world. It bears the climate of Britain veil, and is said to have been cultivated at Holyrood palace so early as the year 1683. It is an ornamental plant in a shrub- bery or large garden. It abounds in the vast plains or pampas of the Cordillera, in South America, and its growth in that part of the world is said to be very rapid. It is stated by a recent traveller in South America, that on the pampas, cardoons shoot up to the height of ten or eleven feet, and come into full flower in the course of a single month. The road G 98 COMPOSITE. and view become completely obstructed by them, and their prickly stems form a barrier of a most impene- trable nature. The same traveller remarks that, though it would be an unusual misfortune in military history, yet it is really possible that an invading army, unacquainted with that country) might be imprisoned by these plants before it had time lo escape from them. There are several varieties of cardoon which are cultivated as culinary vegetables. The seeds are sown in a deep light soil about the middle of April, and by the end of October the plants have attained their full size, and are ready for blanching. This operation is performed by binding the leaves close together with a wreath of hay or straw, and covering them with earth for a month or six weeks. The stems and m,id-ribs of the leaves are stewed, or eaten as a salad. They are also boiled in soups. The florets of the cardoon are used in Buenos Ayres and in France instead of rennet, for coagulating milk. Cynara scolymus, the common artichoke, has been considered by some as merely a variety of the car- doon, depending on the cultivation. This opinion requires confirmation, and as yet we have not sufficient data to enable us to come to a satisfactory conclusion. The artichoke differs from the cardoon in its broad spineless leaves, its humble growth, and its large fleshy heads. The plant comes originally from the south of Europe, and was cultivated in England so early as the year 1580. It is capable of sustaining great and long-continued drought. In the hot season of 1825, it was almost the only vegetable to be got in the neighbourhood of Paris for three or four weeks in the months of July and August. Once in the seventeenth century, and again about 1739, most of the artichokes in England were destroyed by frost, and recourse was had to France for a new supply. There are several varieties of artichoke in cultivation, the chief of which are the green or French. The globe and dwarf globe artichokes are propagated by suckers, in the months of March and April- They require a light well-ma- nured soil, and are planted in rows four feet distant, and two feet apart in the rows. They produce a few heads the h'rst season, and a full crop the next ; and, if well manured, they will last for five or six years. In winter, the plants are covered with dung about a foot thick, which is removed in March and April when the ground is dressed. The artichoke, in its wild state, is more downy and spinous than when cul- tivated in the kitchen garden ; the heads also are much smaller. The heads of the artichoke are gathered in the un- ripe state before the flower expands, and are boiled in salt and water until all the parts are soft which are capable of becoming so. The scales are then taken off one by one, and their lower part being dipped in a mixture of butter and pepper, all the fleshy part is sucked off. Very little is obtained in the way of solid food, the butter forming the chief part of the dish. After the scales are taken off, there remains the re- ceptacle or bottom, with a mass of unexpanded florets and bristles, called the choke. The latter being re- moved, there remains the proper receptacle or cul which is the most valuable part of the artichoke. Many people are very fond of artichokes. In France and Italy they are much more used than in this coun- try, and they are often eaten in those countries in a raw state. Artichokes contain little nourishment, but they are easily digested, and hence are sometimes useful for convalescents. They possess diuretic and diaphoretic properties. The root is bitter, and is considered by the Arabians as laxative, while the gum which it fur- nishes is classed by them among the emetics. The receptacles of the artichoke may be preserved during the winter, by being blanched in hot water, and care- fully dried. The genera Cnicns and Carduus include most of the thistle tribe. These two genera are distinguished from each other by the pappus being feathery in the one, and only rough in the other. Thistles are propagated with amazing rapidity, on account of the down at- tached to their seeds, by means of which they are easily carried by the winds in all directions. They are a very troublesome set of plants, and prove a great annoyance to the farmer. Ever since the time that the Almighty pronounced this sentence on the earth, " Thorns also and thistles shall it bring forth tothee," these weeds have continued to infest the ground, and man has been forced to eat bread in the sweat of his brow. The Cnicus amensis, or creeping thistle, is one of the most difficult to extirpate, in consequence of the numerous deep roots which it puts forth. These noxious weeds, however, although at first sight they might appear to be of no use, have important pur- poses in the economy of nature, affording by their seeds and leaves nourishment to numerous tribes of birds and insects with which the earth is peopled. Some of the thistle tribe are also turned by man to useful account : the footstalks of their leaves, and their receptacles, being used by him as food. The flowers of several of the species ate used in Europe for curdling milk. The handsomest native species of thistle are, Car- duus nutans, Cnicus eriophorum, and heterophyllus. The first of these is said to smell powerfully of musk in warm weather, more especially in the evening, and hence it has been called musk thistle. Cnicus erio- phorum, woolly-headed thistle, is so named on account of the large quantity of woolly matter which is inter- woven with the scales of the involucre. Carduus Man- anus has been denominated milk thistle, on account of the milky veins on its leaves. The root and leaves are very bitter, and the expressed juice was formerly used in dropsy, jaundice, chronic rheumatism, and intermittent fever. Qrwpordum acant/iium, common cotton thistle, although not belonging to the true thistle tribe, and but rarely found in Scotland, is still commonly cultivated as the true Scotch thistle. Its seeds are much eaten by birds, and are not so liable to be blown about as those of the other thistles al- ready noticed. Carthamus tinctonus, safflower, is a native of Egypt and eastern countries, and is cultivated in many parts of Europe and the Levant, on account of its flowers, which are dried and exported in large quantities, in order to furnish a deep yellow dye, like saffron. The flowers furnish two colouring principles very important in dyeing ; one soluble in alkalis, presenting various shades of red, and another soluble in water, of a yel- low colour. The first is employed particularly by the Chinese, to give different red tints to silk, and bears the name of Carthamitc. When mixed with finely powdered talc, it is used by the Parisian ladies as a cosmetic rouge, under the name of vegetable rouge, or lake of Carthamus. The plant was introduced into England in the year 1551, and in 1683, twenty-five acres of ground in Gloucestershire were sown with its seeds. In Spain it is grown in gardens for the pur- COM P OSI 99 pose of colouring soups, and the Jews in Poland em- ploy it much in their viands. The seeds are purga- tive, and have been recommended in dropsy. Though bitter, they are eaten by birds, especially by parrots, and hence they are sometimes called parrot grains. Carthannts lanafus is used by the women in the south of France and Spain for distaffs, and hence it is denominated distaft' thistle. Arctium lappa, common burdock, and Arctium Bar- cfowa.which seems to be merely a variety with a downy calyx, are well known on account of the hooked scales of their involucre, by means of which the heads fasten themselves most pertinaciously to clothes and the coats of animals. The seeds are oily and bitter, and the whole plant possesses diuretic, diaphoretic and aperient qualities. The root contains carbonate and nitrate of potass ; and a decoction of it has been used as a substitute for sarsaparilla, and administered in cutaneous and rheumatic affections. The juice of the leaves mixed with oil forms a liniment which has been used in dressing wounds and ulcers. Contoured benedicta, blessed thistle, a native of the Grecian islands,is accounted a stomachic, and its seeds are used to produce perspiration. An extract from the plant has been recommended in the catarrh of children. Centaurea calcicrapa,commoi\ star-thistle, pos- sesses febrifuge virtues. Its roots were formerly con- sidered useful in calculous complaints, and its leaves and flowers were prescribed in ague. Centaurea cyanus, corn blue-bottle, has been sometimes employed medi- cinally. The juice of its flowers is used as a kind of ink, and stains linen of a blue colour. Carlina acanthifolia is a wholesome article of diet. Carlina acaulis has black woody routs, an inch in thickness, the upper part of which, as well as the re- ceptacle of the flowers, may be eaten. The flowers of Ech'niops strigosus'Ave used in Spain for tinder. II. CICHORACE.*. Most of the plants of this tribe yield a milky juice, which is bitter, astringent, and slightly narcotic. To this juice they owe their medical properties ; and, when it exists in great quantity, the plants may be looked upon with some degree of sus- picion. Many of the CtchoracecE are employed as arti- cles of food, either in a young state, Before the bitter narcotic juice is fully formed, or in a more advanced state, after being blanched. By cultivation a great change is often effected in their qualities. The chief genera included in this sub-division of composite plants are, Cichorium, the succory and en- dive ; Lactuca, the Lettuce ; Smtchus, Leontodon, Scor- sonera/fragopogon, Hicracium, Apargia, Lrtpsana, &c. Cic/ioriitm intybus, common wild succory, is met with chiefly on gravelly and chalky soil, in several parts of Britain, and is very abundant on the con- tinent. It bears numerous large bright but pale blue flowers, which close during the night, but expand on the first approach of morn. The plant was eaten by the Ptomans, and is still used as an article of food in France. The seeds are sown in July, and the plants are allowed to grow six inches apart. In winter the roots are takeu up and packed in a warm cellar among earth, the upper portion being the only part exposed. In this situation, young leaves are quickly produced, in a blanched state, fit for being used as a salad. The leaves and root are very bitter in a wild state, less so when cultivated. The juice of the fresh leaves acts as a tonic, and a stomachic syrup is prepared from them. The root, when dried and roasted, has an agree- able bitter flavor, and is used on the continent as a substitute for coffee. At one time when the latter article bore a high price in the market, succory was much used in France, and it is still employed in that country, although it certainly wants the fine aroma of the Arabian grain. The herb in a luxuriant cultivated state, is an excellent early fodder for cattle. Cichorium endivia, common endive, is a native of Japan and China, and is cultivated in gardens for the purpose ot furnishing the salad which bears its name. The genus Lactuca, lettuce, furnishes several spe- cies, three of which, Lactuca virosa, strong-scented lettuce ; scariola, prickly lettuce ; and saligna, least lettuce, are natives of Britain. Lactuca virosa, wild or strong-scented lettuce, yields a milky juice, having a disagreeable and well-marked narcotic odour. In its medical properties and effects, it bears a considerable resemblance to many of the SolanecB. An extract is prepared from it, which is used as a substitute for opium. A large quantity of this plant was cultivated about a year ago in the neighbourhood of Edinburgh, by a celebrated druggist of that town, and the con- crete juice procured from it was sold extensively in the London market. Lactuca sativa, common lettuce, is another species of the genus. This plant has been cultivated in gar- dens, almost from time immemorial, and its native country is not known. There are several varieties of cultivated lettuce. The leaves of all have a 1'resh, watery, and somewhat bitter flavour, and are used much as a salad. Lettuce thrives well both in tem- perate and warm regions. The inspissated juice of this, as well as the former species, is called lactucarium, and was first introduced into notice by Dr. Duncan of Edinburgh. This sub- stance is called by the French physicians thridace, from the Greek word for lettuce. Although lactu- carium is procured from both species of lactuca, still the lactuca virosa yields it in greatest quantity. The juice, which exists chiefly in the vessels immediately under the cuticle, ought to be collected at the time when the plant is in flower, and the mode of procedure is as follows : — Transverse incisions are made succes- sively in the stems of the plants, and the white or , rnilky juice, which exudes copiously, is scraped off. It j is then put into glass or porcelain vessels, and allowed to concrete by exposure to the air. It thus assumes a brown colour. The thridace of the French is pro- cured by expressing the juice, and consequently it is not so pure as the British lactucarium. Lactucarium varies much in purity, according to the season, as well as the mode of its preparation. It. often contains a great quantity of caoutchouc, which, of course, interferes much with its properties. It lias much of the taste and odour of opium, and exerts a soothing anodyne effect upon the system. Duncan, Young, Scudamore, Bidaut, and Francis, have used it extensively in the cure of diseases. It may be adminis- tered in most cases where the use of opium is indicated in doses of five, ten, or even twenty grains. It would seem not to produce the prejudicial effects which often attend the use of opium. The narcotic principle of lactucarium has not yet been procured in a separate state. No morphia could be obtained from it. Lac- tucarium has also been used as a diuretic in cases of dropsy and water in the chest. The soporific effects of lettuce have been long known. Galen is said to have used it much in the decline of his life, on account of constant wakcfulncss. G2 100 COMPOSITE. The seeds of the lettuce also possess narcotic quali- ties, and the leaves when boiled in water have been used as soothing poultices. Lactuca quercinu, Palmata and Intybacea are culti- vated by the French as salads. Sonchus oleraceus, common sow-thistle, possesses diuretic and laxative properties. The young tender leaves of this plant, as well as those of Sonckus arven- sis and palustris,a.Te eaten as greens in some countries. In Rome and Florence, Sonchus tencrimus is used as a salad. Swine are said to be fond of these plants, and hence the English name soiu-thistlc, which has been applied to them. Sonchus Alpinus bears numerous large blue flowers, and is the rarest British species. It is found only in one or two stations in the Gram- pian range. Leontodon taraxacum receives the names of Dent de Lion, Dandelion, lion's tooth, from the deep tooth- like divisions of its leaves. The plant has a con- siderable degree of bitterness, but when blanched like endive, it may be used as a salad. The tender young leaves, in consequence of being less bitter, are often used for this purpose. The root resembles a carrot, and yields a bitter milky juice, which loses its bitter- ness by drying. When roasted, it is used by the com- mon people in some parts of Germany as a substitute for coffee. Medically dandelion acts as a tonic and diuretic. The expressed juice of the leaves is said to be useful in chronic cutaneous diseases, and in abdo- minal obstructions. In jaundice and diseases of the liver it has also been frequently employed. The plant is a troublesome weed, and is extirpated with great difficulty. The genus Scorzonera derives its name from the Catalonian word for a viper, the plant being consi- dered in Spain to be a remedy for the bite of that reptile. The root of Scorzonera Hispanica, garden or Spanish viper's-grass, is carrot-shaped, about the thick- ness of a finger, and bears some resemblance to the body of a viper. When deprived of its outer skin, and boiled or stewed, it forms an agreeable article of food. The plant is said to possess diuretic, stimulant, and sudorific qualities. The ge.nusTragopogon, goat's- beard, furnishes several species, three of which are natives of Britain. Tragopogon pratensis, common goat's-beard, bears yellow flowers, which close every day before noon. Tragopogon porrifolius, salsify or purple goat's-beard, has a long, fleshy, white root, possessing a mild sweetish flavour, which was formerly used in Britain as an article of food. The plant bears large purple flowers, which close before noon, or in rainy weather. Several of the plants belonging to this section of the Composites, act as horological flowers, their petals expanding and shutting regularly at particular hours in the day. We have examples in the common goat's- beard, the common succory, the common sow-thistle, dandelion, and various species of Hieracium or hawk- weed. These plants act thus as silent monitors, warn- ing us of time's rapid flight. To use the poet's lan- guage— " In every copse and sheltered dell, Unveiled to the observant eye, Are faithful monitors who tell How pass the hours and seasons by. " The green -robed children of the spring Will mark the periods as they pass, Mingle with leaves Time's feathered wing, And bind with flowers his silent glass. " See Hieracium's various tribe Of plumy seed and radiate flowers, The course of time their blooms describe, And wake or sleep appointed hours. " Broad o'er its imbricated cup The Gou.tsbe.ard spreads its golden rays. But shuts its cautious petals up, Retreating from the noontide blaze. " On upland shores, the shepherd marks The hour when, as the dial true, Cichorium to the towering lark Lifts her soft eyes serenely blue. " Thus in each flower and simple bell, That in our path betrodden lie. Are sweet remembrancers who tell How fast their winged moments fly." III. CORYMBIFEIUE. The plants belonging to this subdivision are in general very active in their qualities, and supply various therapeutical agents. Like the other Composite, they contain a bitter principle , and in the composition of many of them we find large quantities of volatile oil and camphor. To the existence of these substances we trace the powerful aromatic odour which many of them emit, as well as their stimulating medical properties. The principal genera included in this section are, Anthemis, ehamo- rnile ; AchillaEa, Helianthus, Absinthium ; Artemisia, wormwood; Tanacetum, tansy ; Balsamita, Matricaria ; Calendula, marigold ; Arnica, Inula, Tussilago, Gna- phalium, Senecio, Dahlia, Bellis, &c. Anthemis nobilis, common chamomile, is a perennial plant, found native in the southern counties of Britain. It is cultivated in gardens for the sake of its flowers, which are easily rendered double, and are used medi- cinally. The plant diffuses a highly aromatic and agreeable odour owing to the presence of a blue volatile oil, which may be procured by distillation. Besides this oil it contains camphor, gum, resin, and a small quantity of tannin. An infusion of the flowers is used as a tonic, stimulating, diaphoretic drink. It is also employed as a febrifuge, and has been admi- nistered with success in slight agues. It produces vomiting, and is useful in aiding the effect of other emetics. Chamomile is used as a remedy in spas- modic diseases* such as hysteria and colic. The flowers are applied externally as a discutient and emollient. Anthemis cotula, stinking chamomile, is another British species, which is found in waste places, in corn-fields, and by way-sides. The whole plant emits a very disagreeable fetid smell, and is said to blister the hands of those who gather it. On examination with the microscope, it is found to be covered with small glands, which probably contain an acrid fluid. The plant is a stimulant, antispasmodic, and is used in nervous diseases. Anthemis pyrethrum, pellitory of Spain, is a native of Spain, Barbary, and other warm countries, but bears the ordinary winters of this country well. The root, when pulled up and applied to the hand, com- municates a peculiarly cold sensation. When chewed it produces a copious secretion of saliva, and a prick- ing sensation in the tongue. It is used in toothach, headach, and palsy of the tongue. It contains vola- tile oil, gum, and muriate of lime. Anthemis tinctoria, ox-eye xihamomile, supplies a beautiful yellow colour, and is used in dyeing. AchilltEa millefolium, common yarrow or milfoil, is found abundantly in pastures and by way-sides in this country. From its astringency it is used in the COMPOSITE. 101 Highlands for the purpose of healing wounds. The root has been proposed as a substitute for snake-root. AckillaEa ptarmica, sneezewort yarrow, when dried and powdered, is employed as an errhine. The root, when chewed, produces salivation. Achillfsa nana, and several other species, are used by the inhabitants of the Alps to give an aromatic flavour to vinegar. Helianthus annuus, common sunflower, is a well known border annual, which receives its name from the popular supposition that its large heads of flowers follow the sun in its course. The plant is common in gardens, and was originally brought from Peru. The whole plant, but especially the flower, gives out a thin resin resembling Venice turpentine. The seeds, when roasted, are used as a substitute for coffee, and an edible oil is procured from them. Helianthus tuberosus, Jerusalem artichoke, is a native of Brazil, but has been naturalised in most countries of Europe, and is cultivated on account of its use in rural and domestic economy. The root of the plant consists of oblong tubers, which are used as a substi- tute for potatoes, and form a wholesome and agreeable article of diet. The roots are very productive. Be- tween seventy and eighty tons of tubers are said to have been obtained in one season from a single acre of ground. When boiled, the roots have a sweet taste similar to the artichoke. The plant may be reared on very poor soil with advantage, but its roots are not so much employed as the potato, on account of the latter containing more nutritive matter in its composition. Chemical analysis has shown that a peculiar principle, similar to that which is found in the dahlia, exists in the root of the Jerusalem arti- choke. The roots when subjected to fermentation yield a spirituous liquor. Absinthium officinale or Artemisia absinthium, com- mon wormwood, is an aromatic bitter plant, common in Great Britain. It contains a large quantity of a green volatile oil. The plant possesses tonic and stimulating qualities, and is used to increase the action of the stomach, as well as for the cure of inter- mittent fever. It is frequently given to expel worms. It is administered in the form of powder, in doses of one or two scruples, also in infusion, and as a wine and a tincture. The green liquor called, in France, ran ot, varyin; somewhat in form, which is its onl v organ of locomotion. All the animals of this family live concealed in the sand or mud, at a greater or lesser depth, but they have the faculty, and sometimes quit that situation; this is effected by contracting the foot, which then acts as a spring, arid they are propelled forward. Their natural position is with the valves downwards when concealed in the sand, and they then move forward by slow degrees, in which operation the foot acts as a lever to assist their march. Under the respective names of the genera composing this family, the parti- cular description of each species will be found. CONCHOLEPAS (Lamarck); PATELLA LEPAS (Linnaeus). By many naturalists, this singular shell has been considered a Patella, wilh which it was classed by Linnaeus, from which it is most widely different, by many characteristics, and particularly by two distinctions, that of having a spire and being an ojiercnlated shell. This error may, hi some degree, he itr'.;iacle,but not possessing Roman stomachs, or perhaps from the want of classical cooks, we confess they appeared anything but eatable to our vulgar taste. As baits to catch fish, many species of shells are used ; we have, ourselves, captured many a bright mackerel and whiting with no other lure than a small piece of mother-o'-pearl suspended from the hook. The amphibious mammalia, sea-birds, and even many fishes, derive a large portion of their sus- tenance from shell fish, which tends to check, with- out destroying altogether, the innumerable broods hourly brought into existence. Except as food, shell- fish contribute but little to supply the other wants of mankind. The Pinna marina does, it is true, furnish with its byssus, or beard as it is commonly called, a silky filament, in sufficient abundance to be fabricated into gloves, stockings, and some few other articles of wearing apparel, but not in such quantities as to render them articles of general use, or commercial speculation, beyond the value attached to them as museum rarities. The Janthina, Buccinum, and other shells, indicate the presence of a strong colour- ing matter, and a species of Purpura produced the highly valued Tyrian purple dye, which formed a very costly article in the catalogue of Roman extravagance ; but the same colour being now ob- tained by the chemical effects of mineral or vegetable matter, at a trifling expense, has, of course, superseded its use. In early treatises on medicine, shells ranked as useful agents ; they, however, now form no part of the pharmacopoeia, common chalk being equally effica- cious. In countries where the manufacture of glass is either unknown or too expensive to be generally used, a shell of the genus P lacuna is substituted to the present day, its extremely thin valves permitting the rays of light to pass partially through them. With these, in China and Japan, the windows may be said to be glazed. As a commercial circulating medium, shells have been employed on the coast of Africa, where sealed bags of the Cyprea monela (money cowry) form tallies for certain sums ; thus exchanging hands in the trading operations of uncivilised nations, as an equivalent for coin, and redeemable by the party issu- ing them with the same good faith that notes are honoured by the firm on which they are drawn. As articles of luxury and decoration, shells, from the most remote period of history, have afforded personal ornaments, in various ways, lo civilised and savage people. With some they are distinctive marks of rank, arid in the idolatrous worship of India, some species are consecrated to ignorant superstition, by those " who sit in darkness and who see no light." The Avicula margaritifera, commonly called the mother- of-pearl oyster, is universally well known as yielding that beautiful iridescent substance, from which num- berless elegant and useful trinkets are fashioned by skilful workmen. It must be observed, however, that the beautiful colours, like those of the Opal, which they resemble, are not the effect of any pig- ment or colouring matter, but occasioned by the mechanical arrangement of the molecules, or atoms of matter, constituting the lamellar substance of the shell, being so distributed as to become capable of decomposing the rays of light, and reflecting the exquisite prismatic hues which all pearly or nacreous shells exhibit. On this subject the philosophical experiments of Brewster and others are highly interesting. It is the animal of this shell, or a dis- eased condition of it, which produces that modest but highly coveted jewel, the Oriental pearl, the pride of Europe's fairest daughters, or Afric's sable children — the gem that decks a monarchs brow, or graces native innocence. In sacred writing, pearls are frequently named as things of inestimable value. " No mention shall be made of coral or of pearls, for the price of wis- dom is above rubies ;" and in Matthew,our Saviour said, " The kingdom of heaven is like a merchantman seek- ing goodly pearls, who, when he had found one pearl of great price, went and sold all he had and bought it." Poets of every nation, but particularly those of the eastern nations, have compared the objects of their dearest affections to pearls, as the most invalu- able things known, its Persian name Mervarid, or globe of light, being constantly used in the hyper- bolical language of oriental poetry. Our native poets have also frequently alluded to pearls ; upon the latin name of which (Margarita), Drumrnond, in his poems, 1656, classically puns in the following lines — In shells and gold, pearles are not kept alone, A Margaret here lies beneathe a stone ; A Margaret that did excel! in worthe, All those bright gems the Indies dothe send forthe. Several other species of shells, both marine and 110 C O N C H O L O G Y. fresh water, also produce pearls — the Pinna marina, Tridaciia gigas, Unia, Mussel, &c. ; they are, however, far inferior in beauty and value, though Suetonius in- forms us that the pearls found in Britain were so highly extolled at Rome, that they mainly influenced Caesar's ' invasion of our sea-girt isle, and though his ambitious j views were only in part realised by the attempt, he ! did not lose sight of one of the inducements which ! led to it, and a buckler, richly decorated with British ' pearls, was placed on his return, in the gorgeous ! temple dedicated to Venus Genetrix, as a trophy of ' his mad ambition, and an imperial offering worthy the sea-born goddess. The rivers and seas of Ireland, Wales, and Scotland still yield pearls ; even to a late date fisheries of them have been established, but the i produce is comparatively of so little value that it no ' longer repays the speculator. A remarkably fine Welsh pearl is said to have been presented by Sir Richard Wynne, of Gwyder, to Catharine, Queen of Charles II., and still to hold its place in the regal crown of England. In the alphabetical arrangement of this work, pearls will be more amply described, and an account of the Oriental pearl fisheries given. Having enumerated some of the known benefits mankind derive from shells, whether as food, ornament, or otherwise, it will be proper to point out such as are injurious, or so considered in certain points of view, that is, so far as their habits tend to defeat the industry or ingenuity of man ; but here, as in the instance of the common snail, we feel called upon to enter a philosophical protest against treating them indiscriminately as destructives and enemies. The evil they commit is certainly manifest, but it is con- fined to a very limited circle— it may be everywhere checked, or prevented by care or art — while the good they perform, being unseen and extended over an immense space, passes unheeded, and, in the present stage of our knowledge of natural history, is not appreciated as it should be ; let it, however, be remembered, that there is an eternal fitness of things which requires that the decrease of various portions of creation should, in some degree, keep pace with their otherwise superabundant growth, thus balan- cing the account of nature's dealings, and regulating the expense of life. Extensive mischief is doubtless committed by that insidious little animal the Teredo, which recklessly wends its way in ten thousand tortu- ous paths, through the hardest oak, or toughest teak, rendering them like sponge, and destroying their texture as supports to submarine erections, occasion- ing, in certain localities, dangerous consequences ; piles, jetties, piers, and vessels, long stationed in some climates, are subject to their ravages, from which fatal accidents have resulted. It is not in human nature thus to witness the destruction of the noblest \vorks of our ingenuity, without condemning the agents that have effected it ; but these are no more than additional illustrations of the fact, that it is for man's ultimate benefit such occurrences should take place — they give a stimulus to his industry — set his wits to work — teach him to counteract the evil com- mitted against his immediate interest or convenience, and often create a far greater eventual benefit than he could at first sight discover. The wise man only becomes so by not despising the humblest information, he is constantly examining, inquiring, or reasoning on everything around him ; and some of the greatest efforts of genius have been perfected from the indica- tions furnished from apparently trivial causes, over- looked at first from their insignificance. Another of the number of shells but little loved by mariners, is the Balanus or Barnacle, whose numerous broods spread themselves in thick congregations, sometimes as it were incrusting the bottoms of ships, and their sides below the water mark, to such an extent, that her progress through the pathless sea becomes seri- ously impeded : the watchful sailor baffled in his best exertions, and the wealthy speculator disappointed in his nicely calculated hope of gain. To conclude our list of commonly called destructives in conchology, we shall add the Photos, and other of the penetrating genera of shells, whose habitations are formed in calcareous, and even stony matter, wood, &c., there performing either good or evil according to the par- ticular circumstances of their situation and the pur- poses of their being, which are, if well considered, probably more beneficial than prejudicial to mankind. Shells are abundantly distributed over ever}* part of the globe, from the polar regions to the torrid and inter-tropical zones, increasing in number, size and colour, as they recede from the one and approximate the other, a fact equally to be observed in the other works of creation. Heat and light, as we shall here- after explain, possess such a prodigious influence on these productions, that the most beautiful, whether marine or terrestrial, are those inhabiting tropical climates. It may be said, that no part of the world is divested of shells, either terrestrial, marine, or fluviatile, and the number of their species is always proportioned to the extent of their peculiar location or habitat ; we may also ascertain that nearly all the families exist in the different zones of the globe, though the genera and species of some are far more numerous in one zone than in the other. To attempt a detailed account of the geographical localities of the different genera, would not only be extremely difficult, if not totally impracticable, but would occupy a larger space than can conveniently be allotted to the subject in a work like the present one; we will, nevertheless, point out a few leading facts with regard to the habitat of shells, which will serve as a general illustration of the localities of their congeners. In the high northern latitudes shells are not numerous, and the species most usually found are of the genera Terebratula, Mya, Pandora, and some of the Solens ; they are not, however, equally abundant in all the northern seas. The Ostrea, Avicula, Orbicitla, Crania Terebratula, Haliolis, Pecten, Patella, Area, l.'nua Mactra, Pholas, Salanus, Cardium, Teredo, and Helix are everywhere found in greater or smaller numbers as the degree of latitude varies ; the Clavagella Aspergillum, and Fistulana, appear confined to the equatorial zones ; the Vulsella, Perna, Chama, Crc- natula, Trigonia, and some of the Cardia, inhabit the southern zones ; the Harpa, Tcrebra, Cassis, Plcuro- toma, Mactra, Strombus, Conus, Oliva, Ovjila, Cypra'a, &e., principally inhabit the inter-tropical regions ; the Tridacna has not yet been met with anywhere than in the Indian archipelago: the Argonauta, Nautilus, and Spirula, mostly dwell in the torrid zone. With respect to terrestrial species of shells, it may be observed generally, that they are more numerous — higher coloured, and of a larger growth, in the southern and eastern regions, than in the northern and inter-tropical. Our Helix ncmoralis, field snail, is, however, a remarkable exception, as its colours vie with those of its congeners in any other country, and C O N C H O L O G Y. Ill in point of size, some species of European Helix ex- ceed those of the warmer latitudes ; the Tcstacclla may be said to live almost underground ; and hot springs, and the bituminous waters of the Dead Sea, are not without testaceous inhabitants. Extremely interest- ing conclusions will, sooner or later, be drawn, as the science of malacology becomes better understood ; respecting the diminution of species, the limits of their variations, and to what extent the individuals are modified by local circumstances in the places they inhabit. Many shells are of a very large size, while others are invisible to the eye. In the formation and arrangement of collections of shells, merely as objects of natural beauty, they cede to no portion of nature's productions ; and, unlike every other branch, they possess this immense superiority, that with a very moderate degree of care, they may be preserved comparatively uninjured for centuries, losing nothing of their substance, and but little of their colour. How truly the naturalist, Pliny, says — " What can be more wonderful than to view nature in all her irregularities and sports in her variety of shells ; such a difference of colour and of figure do they form, flat, concave, long, lunated, drawn round in a circle, the orbit cut in two ; some are seen with a rising on the back, some smooth, some wrinkled, toothed, striated, the point variously intorted, the mouth pointed like a dagger, folded back, bent inwards ! All these creatures, and many more, furnish at once novelty, elegance, and speculation. While I thus contem- plated nature, she wrought in me a persuasion that I should look upon nothing as incredible that related to her." What, indeed, can surpass the freaks and vagaries exhibited by nature in this portion of the creation ? For, whether we admire the graceful symmetry of some, or the grotesque deformity of others, the delicate sculpture, or the rude furrows, the exquisite pencilling and vivid tints, or the bold marking and sombre hue of shells, we are lost in admiration, and the contemplative mind is roused to adore the infinite wisdom that has called all these creatures into existence, and the interest they excite induces us to attempt in some degree to account for their uses. Thus conchology is raised to a more important rank in the march of intellect than it has hitherto occupied in public estimation. We hourly begin to develope new features in its study leading to philosophical results never before contemplated ; and though our progress is so much restricted by circumstances, it will be rendered the more secure from being progressive, and founded upon repeated observation ; we are involuntarily led to assign causes for the effects, and some insight is gained into phenomena that at a first glance appeared most marvellous. Marvellous in truth they must always remain as regards the power and wisdom that gave them life, and invested them with given functions in the scheme of creation. It is, however, to their mechanical structure, if we may be allowed the expression, that our remark applies. In this the exercise of that most invaluable of all gifts, common sense, combined with the tolerably accurate observa- tion of our visual organs, is all that is necessary to those who have not had the additional advantages of an education directed to the improvement of these observations upon anatomical data. This is, how- ever, of the less importance in conchology, treating it, as we now do, as a separate science, and solely applicable to shells, in which point of view nine-tenths of our readers will value it, if they value it at all ; but they must not forget that, as a science, it is most incomplete, imperfect, and artificial ; if the animals themselves are not to be studied in connexion with their coverings, for they ought not, and cannot pro- perly be separated., without violating every principle of natural history, and rendering this branch no more than a classification of differently-shaped pieces of carbonate of lime. It being demonstrable that shells are formed on the model or naked body of the animal construct- ing them, every portion or inequalty of surface these bodies present must necessarily cause either depres- sions or protuberances on the exterior of their shells corresponding with them ; whereas, in the simple snail, these do not exist, or in other shells which have only little elevated knobs, or regular grooves, bands, &c., we easily may conceive how the surface of the shell corresponds with the exterior of the animal's body : and when we examine shells constructed like the Scalaria preliosa (Wentletrap), or the Harpa (Harp), and others of a similar character, we observe the cover- ing of an animal whose periodical increase is distinctly marked by the lip or termination of each addition to its original size. This forms what may, for the sake of description, be termed ribs, when placed longitudinally from the apex to the base, as in the Harpa, or rings, as in the Scalaria ; and here we only want the opportunity of ascertaining the time occupied in constructing each of these additional portion?, to determine the age of the shell. This remark also applies both to bivalve and univalve shells. But when we examine a shell set with spines, or foliated processes, we for a moment hesitate to believe that such was formed in the animal's body ; and here the exercise of common sense is necessary to explain, in the absence of the animal, that which appears inconsistent with the theory laid down ; our reasoning faculties are called into action, and we observe, that in the early stage of growth, many species of shells differ widely from their mature formation, many instances of which may be named in the genera Strombns, Ptcroceras, Ranellrt, CuprcEa, &c., not to mention numerous bivalve shells whose valves are variously provided with spines, arched scales, &c. When such are met with, it is obvious that their formation has been caused by the necessity the animal feels of having certain corre- sponding organs protected, either wholly or partially. In the first period of growth, these organs, not having reached the full term of their development, the shelly matter extended no further than was required, for nature, in her operations, never squanders the mate- rials she employs to cany them into effect ; she always adopts the shortest way of going to work, having no ulterior object to guide her course than necessity ; but that hard taskmaster never drives her from an uniform progress. Combined with the strictest economy both of time and matter, everything in creation hastens on, by regular stages, to iis utmost state of perfection or maturity — there stops — ever after sinking into gradual decay. The purposes of its animal existence daily become more feeble, till they are altogether extinguished by death. Thus, in the genera we have just named, the claws, spiny processes, or terminal bands, could not have been formed from a calcareous deposit on the body of the animal, properly so called ; but we can easily account for their formation, particularly if we have the advan- tage of examining the young and the adult shell at 112 CONCHOLOGY. the same time. In the Pteroceras, here figured, for example, the young shell, instead of the elongated Young Shell. Adult Shell. PTKROCKRAS SCORPIO. points, has open, waved prolongations, which, as the organs they then covered increase in length, become lengthened, and finally closed altogether, as the animal, after attaining its maturity, finds it no longer necessary to go on building, but then retreats into its dwelling, and the very organs most serviceable to complete it not being any longer in constant action, Murex tenuispina. rra«e to grow, and, on the contrary, diminish in size, and very frequently disappear altogether. In other genera, the Murex, &c., we see regularly-formed sets' of spines, or foliations, at given intervals, round the spiral form of the shell. Each of these, it is quite clear, formed previous terminations, and became successively closed as the increased size of the animal required more room. These additions go on with the greatest regularity, and correspond accurately in all the species, with the exception of some few, which may be considered sports of nature, and not generic distinctions. By counting these periodical additions, we come to the same conclusion regarding their age as with the Wentletrap. We can indeed say that such a shell is not an adult one, by counting the number of varices, but it has not yet been determined what period of time is necessary to complete the standard measure. Helices, and their congeners, never form a thickened lip until their full growth is attained. Double-lipped shells have been described, but they are extremely rare. We shall point out the mode adopted by nature in forming the snail shell, in which it will be seen, as before stated, that it ia formed on the animal's body. It is equally certain, though not so easily proved by observation, that those shells which have claws, as they are termed, such as the Pteroceras present, or foliations and spines, as the Murices exhibit, must depend wholly on the form of the skin of the mantle and its age, by means of which these were formed, its lobes, prolongations of portions of the mantle, the organs of respiration, the head, oviduct, &c. ; each producing, by their habitual uses, the spines, claws, canals, and other parts of the ex- ternal covering of the animal. If the edges of the mantle of the animal are even, the termination of the shell is the same ; if waved, so is the external edge. Where digitations of the mantle exist, they are equally protected, and become, as we have stated, claws or spines ; tubular in their early growth, but rendered solid by repeated deposits of testaceous matter, exuding from the mantle in certain propor- tions, till the period of its full maturity. The animal then declines ; its dwelling is sufficient for the pro- tection of its body ; the wants of its life in seeking food, or in moving from one spot to another, during the completion of its growth, require an extension of those parts, at first but slightly defined, and they are not in the full exercise of their adult functions ; but these extended organs in youth are much greater in proportion, and frequently more numerous, than they are in the stage of decrepitude, when they begin to disappear, and the activity of their offices gra- dually decline, being no longer required to complete most of their destined operations. As a general deduction, we repeat, it appears quite certain that the spines, tubercles, and claws of shells, however solid they may be met with, have all of them, at first, been channelled or grooved, to defend certain ex- posed organs in those which have the canal or slit on the under side, and they are by far the most numerous, having been produced by the digitations of the mantle ; while those which have the slit on the upper side, as in the Purpura and Venus Dione, (Linnaeus) appear, on the contrary, to have been produced by the concavity of an appendage to the mantle, which projected on the outside. Nothing certain appears known of the age of shells, though we have just remarked that certain stages of growth are marked by signs of the shell being then finished ; their growth probably in many species, under favourable circumstances of climate CONCH O LOGY. 113 and food, continues for a definite period ; with regard to the animal, whose increase of bulk requires increased accommodation in its shell, as would appear particularly in the genera we have already named, and in all the other genera whose varices, whether spinous or foliaceous, seem placed at stated intervals, some being found at the half turn of the whole circumference of the shell, others at a quarter, some one third, and some perpendicular to the base ; others at the sides of the shell, giving it a flattened or ventricose appearance, according to the position of these previous terminations, which, it must be again observed, are formed of the vitreous, and not lamellar substance. In bivalve shells, also, the period of growth may be traced by their striae, and they seem also to have a limited extent of increase, as, generally speaking, the various genera attain a tole- rably uniform size. Their age is, however, more strongly marked by the thickness of the valves, and the internal muscular impressions, than any other guide. The valves of shells having a continual tendency to fly open, in consequence of the elastic ligament situated at the side of the hinge, which operates as a muscle, it was necessary that the animal inclosed should have the power of closing them at pleasure. There are, therefore, according to the different genera, alwa3rs one or two muscles fitted for this purpose. In the oyster there is only one muscle of this kind, situated near the centre of the shell, behind the liver, and in the middle of the cloak. It is inserted into both valves, and by its contraction brings them together with an astonishing force, equal to the pressure of many hundred pounds weight. The same mechanism prevails in the 1'er-na, Avicula, and Spondylus. In young shells these muscles leave a fainter impression than in old ones, in which the increased substance of the valves render them deeper. They are, as it were, always advancing more towards the edge of the valves, not that these muscles are ever displaced entirely, but new portions of them are formed as the animal finds it necessary to occupy a convenient position in its dwelling ; the posterior parts of the muscle become inactive, and die away, whilst others replace them on the anterior part, and so on during the life of the animal. These muscular impressions also afford an excellent guide to the genus of animal to which a shell belongs, where no other opportunity presents itself of judging. The difference which exists ia the size of shells of the same species, particularly in such as have not the strongly marked lip, or other final termination, is very remarkable. It does not appear easily accounted for, but a similar anomaly exists in every branch of natural history ; and it may therefore be attributed chiefly to the strength and constitution of the ani- ;mal, being always proportioned to the favourable or unfavourable situation of its habitat, and the goodness of its nourishment in peculiar situations. Another extraordinary occurrence is, the elongation of the spires of some univalve shells, in which the whorls do not touch each other, but appear drawn out like a coiled spring. The Scalaria and Helix are those in which that lusus has been observed, though it is very rare ; but the greatest monstrosity of all, the most inexplicable freak of nature, is dis- played in such shells as are sinister or heterostrophe, that is, having their whorls turned to the left instead of the right. This can only be accounted for by the viscera of the animal presenting a change in their • NAT, HIST.— VOL. II. position, which of course is followed in the formation of the shell, this is to be understood, but the former baffles inquiry. Such a phenomenon might therefore occur in every species of mollusc, and does so in numerous instances ; but some of the genera, parti- cularly of terrestrial shells, are more commonly left- handed than on the contrary. These, however, do not, in the opinion of the author of this article, con- stitute anything beyond a variety or sport of nature, though constantly occurring in some genera. The probable number of shells in a recent state, can only be guessed at ; as, in addition to the species already known,, naturalists and travellers are con- tinually increasing the amount by new researches ; but judging, which may fairly be done, from the immense beds of the vestiges of former testaceous animals, we may conclude, that living examples exist in countless myriads. The mode of production is various ; some of these creatures are viviparous, or bring forth their young alive, as is the case with most of those which inhabit bivalve shells, multivalves, and even some of the uni- valves, while others, which form by far the greater portion of such as are known, are oviparous, or produce their young from eggs. The animals con- structing shells, do not, generally speaking, exhibit any known affection towards their progeny, though many possess that wisdom termed instinct, in deposit- ing them not only in secure places, but especially where food, the first want of nature, will be amply supplied, without much trouble to obtain it. Adarison mentions that the female of the Voluta gondola of the Linnaean school, collects its young for some time together in the fold of its foot, 'and the female of the oviparous Paludina also carries its young some days on its shell. Species of the Succinum, Purpura, and probably many other genera, whose eggs are pe- dunculated, or having a stem, are. attached, at their exclusion, to the neighbouring substances. The Janthina, which is always found floating, surrounds its shell with eggs ; the snail and others of its congeners conceal their eggs in the hollow of trees, beneath stones, in damp places protected from the sun ; the Ocythoe, of the Argonauta, appears to place its eggs at the bottom of the shell it inhabits ; muscles attach their youna: by means of their channelled foot ; and Balani do ihe same with the long tube which terminates their oviduct. Most other molluscs lay their eggs as chance directs ; and it is possible, from the viscous matter that surrounds them, they are enabled to adhere to marine substances, where, at the period of their development, they find themselves the most advantageously placed according to their future wants and habits. By far the greater number of eggs produced by molluscous animals are mucous ; some are horny, and some are covered with a calcareous coating, resembling those of birds, as is the case with one or more species of Achatina and Bulinus. In one fact all naturalists agree, that whatsoever the mode of production, whether from an egg or otherwise, the shell is formed on the body of the young animal proportioned to its then bulk ; the increase this shortly requires, and the consequent necessity of enlarging its shelly dwelling, we will now explain. For this purpose the common snail shall be our preceptor ; its example holds good with all shells, being formed of spiral convolutions, whether they are aquatic or terrestrial. The princi- pal use of shells is, doubtless, to cover the animal entirely when in want of such a protection, or merely H 114 CONCHOLOGY. to defend certain delicate organs most subjected to injury. Some writers have considered them analogous to the bones of other animals, although its formation and growth arc widely different, since it serves as a base or support to the muscles which are attached to its internal surface. Reaumur, to whom we are indebted for numberless interesting and accurate observations of the pheno- mena of nature, thus describes the increase of shell which takes place after the development of the animal and its progress of growth : — " The enlargement of shells after this period is owing to successive additions of calcareous and animal matter, independent of any organised structure. When a testaceous animal is about to enlarge its shell, the common snail for instance, and its body has become too large to be covered securely, it projects a portion of its body from the opening ; it then attaches itself to a wall or other solid substance, and the naked part is soon covered with the fluids which are excreted from its surface ; the pellicle, or covering, which they produce, when the fluid dries, is, at first, thin and elastic, but gradu- ally assumes more consistence, and becomes at last similar to the whole part of the shell. If, in this stage of the process, a bit of the shell is broken off and removed without injuring the body of the animal, the skin of the snail is soon covered with a fluid which gradually thickens and becomes solid. In about twenty-four hours after the operation a fine crust may be observed, which constitutes the first and external layer for repairing the breach that was made ; at the end of some days this layer becomes thicker, and in ten or twelve days, under favourable circumstances, the new piece of shell has acquired the same thick- ness as that which was removed, but it never unites in the same way, being only as it were a plug. If, after the broken piece has been removed, particularly if the fracture is made near the edge of the opening, the animal is not supplied with a sufficient quantity of nourishment, its bulk is soon diminished, and now finding what is left of the shell equal to com- pletely cover its lessened body, no exertion takes place for the production of a new portion. It is obvious, snails, &c., cannot enlarge in volume but by the augmentation of the whorls, and that each previ- ous turn of the spire remains the same in length ; these make a great difference in the size of the shell, by the last and additional one, each being calculated to contain nearly double that of the preceding one ; but in many shells, both marine and river, the last whorls of the spire, compared with the preceding ones, greatly exceed this proportion. In some, the external opening is twelve times greater, or from eight to twelve : this depends entirely on the increase of the animal's body, and the duration of that increase. Those testaceous animals which have only a few turns in the spire of the shell are of this description ; to the former belong such as have a greater number of turns ; the growth of shells, being proportioned to that of the inhabitant, proceeds almost imperceptibly. In most shells this, however, is marked on the convex side with lines, more or less fine, giving the shell a fibrous appearance ; these are called striae, which may be traced through the whole of the shell, in bivalves and in the longitudinal direction of those which have a spiral form ; they cannot receive any addition without that progress being discovered on a minute examina- tion. These inequalities must become visible, for the smallest addition of testaceous matter which is made, must be attached to the old part of the shell, and con- sequently, must be more elevated than the former ; whatever be its thickness, the increase, or rather the interruption of the growth is thus distinctly marked; and they have some degree of analogy with the different shoots of trees, checked by the cold of winter or advanced by the heat of summejr, as is remarked in such shells which live on the land, or inhabit rivers in temperate regions ; in these the shell is not enlarged during those seasons ; it is otherwise, however, with regard to its thickness, for that is con- tinually going on, from the constant exudation of small quantities of fluid from the animal's body ; this addition is generally marked also by a fresh coloured stripe or band, darker than the present one." That which appears certain is, that the growth of shells is extremely slow, and that their inhabitants are able to exist a very long period without food, parti- cularly such as can screen themselves entirely from exterior circumstances, as is the case with the Helix. This is the more remarkable as the animal has not a stock of fat to exist upon as in some hybernating animals ; that substance never existing in molluscs. Numberless instances of this could be adduced, and among others proving the tenacity of life in snails, the writer has received some of their species closely packed with marine shells from the Mauritius, which the day after their being unpacked were discovered wandering about, apparently uninjured by their con- finement. Some lived ten days, but a want of proper food, or more probably an uncongenial climate, then killed them. Another instance is recorded in the Philosophical Transactions, of snails having resumed their wonted habits, after having been imprisoned in a cabinet fifteen years ; this is not, however, vouched for by the writer of this article. These remarks are so easily corroborated by every day's observation, that they need not be enlarged upon, and those who are disposed to examine some of nature's interesting operations, will do well to begin with such as are not attended with philosophic cruelty ; and as the formation of the snail's shell illustrates the growth of all similarly constructed habitations, a more attainable object cannot well be pointed out. Having, as we think, explained the mode of increase adopted by the animals of a large proportion of the various genera of shells, we will now shortly describe a difference which exists in another very extensive division, called, by some naturalists, porcelain shells, on account of their smooth surfaces and high polish, resembling china-ware, in these there are two sets of colours, disposed in a parallel direction to each other. The external range of these colours is owing to a peculiarity of structure in the animals which inhabit them, different from that of other testaceous animals, and to an operation which does not take place in other shells. In these shells the colouring matter seems to be always deposited in two different ways, and at two distinct periods. In the first process, when the body of the shell is formed, the colouring matter is excreted from the glands in the body of the animal, and it is arranged according to the disposition of those glands. At this period the shell is only of a very moderate thickness, much less than it after- wards acquires when completely formed. On -the external surface of the shell thus formed, another layer is deposited, which is more compact than the former, in some places thicker than in others, and usually variegated with different colours ; the external shell CONCHOLOGY. 115 being thus completely covered with the second layer the original colours are concealed, and if the same shell were examined at the different periods of its growth or increase, it would appear like two distinct species. In the genus Cyprcea (common cowry), this is strikingly visible ; the young shell is thin ; the spire formed by its convolutions very distinctly marked, and the toothed, or grooved aperture, not at all indicated : in this stage it closely resembles some species of cones, and by early writers on concliology has been so classed. As the external deposition of matter continues, the thickness of the shell increases, the spire becomes less and less, till it is altogether obliterated, and an indentation is formed on the part it occupied, by the repeated coverings it has received ; the matter also undergoes a change of quality ; becomes more glassy or transparent, for it is to be remarked, that when a shell has attained the largest growth it is susceptible of, the skin of the animal appears to produce a greater quantity of calcareous, and less of the gelatinous matter ; the atoms com- posing it are no longer in regular layers or leafy, they have become extremely compressed and neaped together, their structure vitreous, and assuming a i? Shell. Adult Shell. RJBA EXANTHEMA, brilliant polish, from the continual friction of the parts of the mantle, as they pass constantly over the surface of the shell during the life of the animal ; this is observable in all univalve shells, most particularly so in the cowry and its congeners ; each addition to the rolled form of the shell is rendered thicker, and, when it has reached its full period of maturity, the lips of the opening are become extremely thick, and with those grooves which admit certain portions of the animal's body to pass through. Thus, the different modes of increase may readily be understood, and it is plainly quite distinct, from that which we have described as taking place in the snail and similarly constructed shells, in the one, a shell may familiarly be termed built by small additions of matter to its first formation, placed as it were in lines, edge to edge, as any thin substance would be rendered wider by care- fully laying a coat of varnish on its edge, adding various others in succession, as each previous one becomes hardened ; while in the porcelanous shells, the depo- sition of matter is layer upon layer, over the whole surface of its broadest expanse, or in more scientific terms, stratum super-stratum. The lamellar structure of shells may easily be dis- covered by exposing the common oysters, and such as are so constructed, to the action of heat, when the animal matter which cemented the calcareous layers is destroyed, and they are shown in a foliaceous form. The fracture of the shell is another fact illustrative ot' its formation ; an oyster never breaks short off, but in thin scales or portions, while the snail and bivalve shells break short off in the direction of their additions to the edge of the shell, some more readily than others, according to the density of the matter com- posing them. In the matchless Museum of the Royal College of Surgeons, there are some beautiful prepar- ations of shells and madrepores, in which the calcare- ous portion of matter has been absorbed by a chemical process, not affecting the animal matter, which remains exhibiting the precise form of the shell, by far the greater proportion of which it constituted. The chemical analysis of shells has been carefully made, and its general result proves them to be formed of a gelatinous matter hardened by a calcareous salt. The species which contain the largest portion of animal matter, appear to be those of a fibrous and pearly structure, in these exist sub-carbonate of lime and coagulated albumine. Mother-of-pearl itself is com- posed of sixty-six parts of the first and thirty-four of the latter. The shells of oysters contain much less animal matter, and that which does exist, more resembles a gelatinous substance ; Vauqueline dis- covered in it sub-carbonate of lime and phosphate of of lime, with sub-carbonate of magnesia and oxide of iron. The Patella (limpet), which is formed of an ex- tremely compact lamellar structure, approximates the most, in its chemical composition, those shells, which are, in general, vitreous, or, as it is termed Porcellanic ; these contain only a small proportion of animal matter, but a very large one of sub-carbonate of lime, without any traces of phosphate or sulphate of lime. Human chemistry has brought to light many wonderful pheno- mena, and has gone some length in elucidating them ; but great as these discoveries have been, they are no more than as distant planets in the wide-spread firma- ment, when compared to the operations incessantly performing in nature's laboratory. By the aid of chemistry we may, indeed, decompose nearly every substance in nature — dissolve some of them into air — collect the gases again, and prove, by the test of the most accurate weights, that no portion of the original bulk is lost, though rendered invisible to the eye ; it is therefore, almost demonstrable, that the globe weighs no more at this moment than it did at its first creation, the destruction of some portions of it con- tributing to the formation of others, nothing being lost. But here, human science stops ; we cannot take the elementary atoms and fashion them into a rude oyster or rough pebble ; in this the master touch is wanted, all the accumulated wisdom of ages past, or of generations to come, can do no more, can go no farther, than to approach nearer and nearer, by slow degrees, the impenetrable barrier eternally fixed be- tween omnipotent wisdom and finite judgment. Another constituent portion of many shells is an external covering called the epidermis, the precise use of which does not appear satisfactorily explained ; it is evidently the epidermis of the animal's skin beneath which the shelly matter has been deposited 116 CONCHOLOGY. This epidermis is formed of a dried mucus, or horny matter, forming1 a covering more or less thick — in some shells it is more or less united, in others thick like fur, or disposed in ridges. In bivalves this part is formed of the same substance as the ligament, and sometimes totally envelopes the valves, as in the Mt/a, Solen, &c. Its growth keeps pace with the increase of the shell, whether it afterwards remains upon it or not. The opercula of shells, though not absolutely a portion of them, nevertheless belong to the animal possessing them, and which, in the modern arrange- ment of Malacology, must be studied with their cover- ings ; these interesting parts have been scientifically treated by Mr. Gray, F.R.S. ; they tend greatly to assist in the classification of molluscs, to point out their structure, peculiar habits, and to form an admir- able guide to localities, otherwise without positive indications. The colouring matter of shells may be said not properly to belong to them : it is always extremely superficial, and is produced by the coloured pigment secreted on the surface of some portion of the animal's body ; these are coloured atoms, deposited above the calcareous matter, and are of a different nature, since they form no necessary portion of the shell's strength, disappearing under circumstances of age, injury by artificial heat, the application of acids or other causes. The colours are always more vivid in young animals, and the recent portions produced by them. Anatomists have proved, that it is only the limb or anterior edge of the animal's mantle which produces these colouring molecules, for, if a hole is made in any other part of the shell than at its edge, the reparation is made with matter quite colourless, and forms a white spot. In the snail (Helir ncmoralis'), which is so elegantly zoned with bands of black upon a yellow ground, it may easily be seen that the portion of the animal's body corresponding with these, presents a tinge of that colour, so that a fracture made there, on the extreme edge of the shell, is restored by a similarly coloured portion to that injured or removed, provided the broken part is altogether removed, otherwise, we see in the snail, inhumanly crushed to a shapeless mass, repeated proofs of the reparations made by the animal being perfectly colourless, every where but at the lip of the shell ; in this state examples may occasionally be met with, so industriously mended after what was deemed a total destruction of the animal, that its shell appeared made up of numberless patches, as variously disposed as Harlequin's jacket. Though we have no certain proof that all other shells, whose coloured zones run spirally from the summits, are similarly formed, analogous reasoning authorises us to draw that conclusion ; but with species whose colouring matter is externally deposited in oval, square or irregularly formed spots, and parti- cularly where the transverse bands, or stripes, are in the direction of the additions to the shell's growth, that is, perpendicular from the summit to the base, the analogy is not so evident-; without we subscribe to the doctrine of some naturalists, that there is a change, a displacement, either regular or not, in the colouring parts of the animal's mantle, under peculiar circumstances of structure, constant and undeviating as any other of nature's laws. These phenomena admit, however, of much speculation, arid can only be explained by a long series of accurate observa- tions of the animals themselves in the different stages of their growth, a thing so difficult to come at, and requiring a particular train of study to benefit from, when within our reach, that we must content ourselves with well-grounded supposition, in the absence of positive proof. We have just, said that the coloration of shells is constantly superficial ; this, however, must be qualified when speaking of such shells as we have described under the name of porcelanic, the cowry, and some species of olive. The formation of the cowry hav- ing been explained, it is obvious that, during the animal's young state, the colouring matter is external, and proceeds from the same causes as in other shells. This coloration is due to the edges of the mantle, and is gradually made as the animal increases in size ; but, probably at a later period, when it has attained its complete maturity, the cutaneous append- ages on each side of the animal's body, when it climbs, are elevated on the bick of the shell, depositing that vitreous or glassy ivory coating, which gradually thickens it, and at the same time leaves a colouring matter, constantly presenting a different disposition to the first. It must then be admitted, that the upper part of these cutaneous lobes possess intervals where the pigment is coloured, imbuing the cretaceous matter exhaled from them ; and, as it is very unlikely, indeed almost impossible, that these spaces or inter- vals in the development of the lobes, should exactly cover the part on which the colour is deposited a second time, it is easily to be conceived that the markings are necessarily irregular, and can never exhibit either bands or any other running design. An examination of the leopard cowry, in its adult state, will render this subject easily understood, and in the map cowry, though a more rare shell to meet with, it is yet more strikingly illustrated ; in this, the space not touched, or totally covered, by the cutaneous lobes of the animal's body, is distinctly marked by well-defined lines, distributed in various curves like the face of a map, from whence its appropriate name. This is visible in the common and other cowries, but not so strongly marked. We must also remark, that the colouring matter of some shells is occasionally on the internal surface, of bivalves in particular. In these exceptions to the general rule, the effect may be attributed, we think, to the matter deposited, and it appears to be produced by an impregnation of colour, gradually extending in depth as well as surface, occasioned probably by some humour of the animal's body, produced in any organ, the immediate contact 6f which with the shell, tinges it of the colour of that secreted fluid. This appears to apply to the yellow and brown interior of some univalve shells, which certainly is caused by the liver of the animal being in contact with them ; the JantMna is also coloured by similar causes. It may, however, be generally asserted, that it is extremely rare to find the component strata of shells otherwise than white ; they are, however, sometimes, as has been stated, both externally and internally, tinged with colouring matter. We said that light and heat exercise a prodigious influence in the colouration of shells, as well as it does in the other portions of creation. All such as are inclosed in the interior of the animal, in holes of wood, chalk, or in other situations from whence they never emerge, are constantly white; but another more striking example may be adduced from certain bivalve shells, which being fixed more or less h^rf- CONCHOLOGY. 117 rontally, even where one valve is not attached to any substance permanently, the lower side is always colourless ; the Spondylus, many Pectens, and some other genera, fully illustrate this fact. Shells inclosed in sponge, or other foreign bodies, are invariably colourless. It must, therefore, be admitted that one lobe of the animal's mantle not receiving the exciting action of light, produces no colouring pigment, and the contrary with regard to the other ; or perhaps the pigment itself only becomes coloured by the action of light on the fluids of the animal's circulation, so that if the shells were removed from the place of their habi- tation, and their position reversed, there would be a consequent change in the coloration of their valves, which is exhibited in some species of the Pleuronecta. It may generally be remarked, that those shells the most exposed to the action of light and heat, are invariably the most brilliantly coloured. The Helices, which are terrestrial animals, in fact, vary the most in colour, and have them of the most vivid tints ; but when they inhabit the umbrageous shades of the forest, they become paler, and less distinctly marked, than the same species living in open situations ; the coloured portions of the shell itself are more intense than those partially concealed of the samfe hue. Almost every colour of the rainbow is to be met with in shells, varying in their degree of intensity ; the most common, however, are the brown and fawn ; green is incomparably the most rare, the peculiar markings of these colours depending upon the ana- tomical structure of the animal secreting them, cannot so clearly be understood as we could wish ; indeed, the causes are as yet very incompletely known, but they are infinite in their combinations and variety, and baffle the skill of man to imitate. What can exceed the beautiful pencilling of the Cones and Volutes, or the vivid hue of their colours, and those of many other genera too numerous to be here named. It being understood that shells are the protecting coverings of the animals formingand inhabiting them, that they are of various forms, corresponding with the naked body of the animal ; more or less thick, ths fracture either short or lamellar, and constantly at- tached to the body of the animal ; we shall now pro- ceed to explain some of the technical considerations connected with the study of the science of Tcstace- ology, without any reference to its enlarged view, which will be entered upon under Malacology. In the first place, considering these bodies in a general point of view with regard to their structure, the first divisions of shells may be considered between those that are called true or false. A false shell (pseudotcsta*) is that not belonging to a molluscous animal, or rather a shell composed of small polygons, placed side by side, the whole forming a hard, brittle, calcareous envelop, as in the Echini. A true shell is that which is formed by laminae or strata, each one placed beneath the previous one, the most recent and considerable being the last internally deposited, the smallest in substance and the oldest in formation being the exter- nal ; this applies to every species of shell, whatever may be its form, or the number of pieces composing it. A general study of that form occasions another divi- sion between such as are tubular or not, but little explanation is necessary to point these out, as every one will easily recognise them from such as are spi- rally formed. The nontubular shells are divided into such as consist of one piece— these are the univalves ; the sub-bivalves are those consisting of a principal and an accessory part ; bivalves are all those consisting of no more than two pieces ; tubivalves are such shells as have two principal pieces, with an accessory one ; and the multivalves are such as have a greater number of portions or pieces. A valve is therefore a calcare- ous portion of shell, varying greatly in point of form, either concealed within the animal's skin, or protect- ing a greater or smaller portion of the animal s body. Multivalve shells are of three descriptions ; those that are composed of transverse pieces, as in the Chiton ; those that are formed of five valves, or more, symme- trically arranged to the right or to the left hand, some- times placed in the form of scales united together by means of the animal's skin ; these form a division established by De Montfort, under the title of dissi- valvcs, as occurs in the genus Anatifera; ; and, lastly, those shells in which the pieces or valves are placed in a circular manner, as in the genus Halamts and its congeners, which form Lamarck's sub-coronals. Tubi- valve shells are those composed of two principal valves, as in bivalves, properly so called, but sur- rounded or enveloped by another piece in the form of a tube, which, nevertheless, cannot be considered as another valve ; this is observed in the genera Teredo, Fistulana, &c. Bivalve shells are such as their name indicates, formed of two pieces, these two pieces notwithstanding being only one cover or dwell- ing for the animal inhabiting it; they are nearly in every instance placed on the sides of the animal, and connected with each other, inasmuch as the functions of the animal are double, and those which apply to one valve apply equally to the other. Where the valves are not entirely similar in their configuration much error has been occasioned ; and Linnaeus considered the Lingu/a an univalve, having seen only one valve, in the genera Orlncula, Cliama, and some others ; the dissimilarity of the valves, were they not well known to naturalists, might lead to similar false conclusions. Sub-bivalve shells are those in which, besides a piece analogous to that which constitutes the univalve shells, there is a second more or less perfect— cal- careous or otherwise*, closing more or le*s completely the aperture of the shell, which piece is called the operculum. Univalve shells merely present one constituted piece, no matter what its form, or how differently it may be modified in the different species ; it altogether forms an asylum for the animal in cases of repose or danger, or, as we have already stated, protects such organs of delicate sensibility at are the most exposed to accident. An univalve shell may be completely tubular, or entirely concealed in the animal's skin. Having drawn these distinctions, we will proceed to examine each of these species of shells, commencing with the most simple, and going on to the most com- plicated structure ; but, in the first instance, we will define the terms derived from the analogous habits of each, which consequently apply equally to univalves as well as to bivalves. Shells, no matter what num- ber of pieces compose them, must be considered as alike in various circumstances common to till, which we will rapidly examine. From the situation in which Molluscs are found, they have been distinguished into terrestrial ; rluviatile, or those inhabiting fresh water ; and marine, or those dwelling in salt water. Terrestrial are such as are found on land, and are so organised as not to be able to exist in a tluid ; they breathe air only. 118 CONCHOLOGY. Such only are known in the division of univalves and sub-bivalves, as it is quite impossible that bi- valves or multivalves, which are tenanted by aquatic animals, breathing water, should be found on land. Terrestrial shells are generally very thin ; their exterior surface usually smooth, presenting no other inequalities than the striae, indicating the different stages of growth, sometimes with pilifonn prolonga- tions of the epidermis, but never with spines, or other protuberances properly so called ; their internal or external surface is never pearly ; their aperture is always entire, particularly in the adult state, with the right side of the lip thickened into a ridge more or less turned outwards. Fluviatile shells comprehend all those that live in fresh water, whether stagnant or current ; some of them are found in the three first divisions of shells, •viz. the univalves, sub-bivalves, and bivalves, but none are yet known in the multivalves ; the number of fluviatile shells is considerable compared with the others, and is confined to a very few families. So amongst univalves, the greater number known have the aperture entire, either operculated or not, but above all in the last group. One or two genera, at the most, have it grooved, though very slightly, as in the Melanopsis, and there is perhaps only one genus in which it is patelliform, like a Limpet. The bivalves of this section only belong to three or four families ; the only ones known are those of the Mytilus, Sub- mytilus, Chama, &c., and even then it is often a single genus, or a solitary species. Fresh water univalves and sub-bivalves arera'general thin, since they belong to swimming animals ; their external surface in gene- ral finely striated, without bands or varices, but some- times with spines ; and when there is an epidermis, it is always very thin. One of their general characters is that of having their aperture entire, but the Mela- nopsis forms an exception to the rule, not only in that respect, but as being often of a considerable thick- ness : thus the distinction between fresh water uni- valves and sub-bivalves is less easy than in the terrestrial. Fluviatile bivalves are nearly in the same case ; it has, nevertheless, been remarked, that whe- ther the substance be thick or thin, they have nearly always a rather thick epidermis, the valves shut completely, they are more or less pearly within, and the summits decorticated in most species. Marine shells may be said to exist of all families, except those of the snail, and other of their congeners, and of the first section of the Submytilus among the bivalves. Their characters are opposed to those of the two first sections. Thus the univalves, and even the sub-bivalves, are in general much thicker, and more frequently marked with ridges, varices, and spines. Their aperture also differs from the preceding, by being very frequently channelled, and bordered on the right side by a simple or complex ridge. They are sometimes pearly on the inside ; the epidermis is often scaly, piliform, and, generally speaking, totally different from either the fluviatile or terrestrial species. Marine bivalves are in general more rough on their exterior, with more strongly defined striae, grooves, and rays ; their epidermis is less smooth, even thinner, and usually of a very different form from that of the fluviatile shells. With regard to the parts of rivers, lakes, and seas, in which molluscous animals live, they are sub-divided into littoral and pelagic shells ; the littoral are those, either univalves, sub-bivalves, bivalves, or multivalves, which inhabit more or less constantly the sides or banks of rivers, lakes and seas ; the pelagic are, on the contrary, those molluscs always inhabiting the deepest parts of the sea, in consequence of which they are the most difficult to come at, and but generally only known through accidental circumstances. There is not, however, any permanent distinguishing character for these shells, so as to enable the naturalist to decide, by an examination of the shell only, to what habitat it belongs. A moderate degree of experience will, nevertheless, give certain rules going far to establish the fact, without any knowledge of the animal. There is not, either, any indications on the shells themselves to point out such of them as are found embedded (in some instances it is difficult to say how) in wood, stone, &c. As a general defini- tion, these are called (Terebrantes) borers or piercers, and distinguished from each other, as Petricolce, or Lithodom<£, when found in calcareous substances, of a more or less hard texture, as with the Pholodes, &c. ; Xylodomce, or Lignivorce, when they have established their habitations in wood, as is the case with the Teredo: Arenicoke, when they inhabit the sand ; Lutricol<£, when buried in the mud of rivers, ponds, &c. -An observation may, however, be here made with respect to such of the penetrating molluscs which inhabit hard bodies. They are only to be met with in some families of bivalves, and a tolerably uniform indication may be discovered in the larger and more rounded form of their anterior extremity. It is also pretty easy to distinguish, by certain marks, such molluscs as are more or less fixed in their local habits. These shells may be divided, in consequence, into those being (Natantcs) floating, that is, inhabited by swimming animals. They are then wisely con- structed of a very thin light substance, which is beautifully exemplified in the Argonauta, Janthina, Sulla, and others. The Libcrce, or free shells, are such as are more solidly constructed, and presenting no sign of ad- herence, or power of attaching themselves to sub- marine or other bodies. This is the case with the greater proportion of shells. Adluzrentes, or adhering, when they are altogether immovable, or only possessing the power of moving in a very limited space. To the extent of their attachment, these are denominated FixtE, or fixed, when their attachment is by means of the adhesion of the substance of the shell itself, as is the case in univalves with the Hipponix ; in the bivalves with the Spondylus, Oyster, Chamae ; and in the Balani among the multivalves. Radicate, rooted, when the adhesion is effected by means of a tendinous part, as is the case with the Terebratula and Lingula in bivalve shells ; the Atiatifce in multivalves. This Linnxus improperly designated intestinum, an error perpetuated by Bru- gniere, who translates it intestine. This adhering portion is often marked in the shell, but it is some- times indicated by a hole or groove in one of the valves ; and lastly, molluscs are called Obtecta, or hidden, when they are concealed at a certain depth in a distinct tube, to which they adhere, or remain loose, enveloping the animal altogether, as in the genus Fistulana and its congeners. We will here describe the position of the shell as viewed by modern naturalists, in describing the various names ascribed to its differen^ parts. In this a well-marked and C O N C H O L O G Y. 119 extremely rational change has taken place Since the revision of the Limuean school ; and it is now the more useful, as it tends to facilitate naturally the connection we deem inseparable of the animal and its dwelling, which forms the leading feature of the science of Malacology. Our present object is, how- ever, confined, as we have already premised, to the shells themselves, as detached portions ; and before we proceed to the nomenclature of the science, the following easy guide should be well retained in the student's memory. It will be the more readily understood by an examination of the accompanying descriptive figure ; or we may at any time observe the march of our garden snail as a living guide to the subject. In uniAlve shells, it is easily conceived that they must have had a point or portion from whence they progressed in growth, a base which is its actual termination in its final stages of increase, or in its adult state of maturity, with an intermediate state between these, which may be called the body of the shell. This portion sometimes possesses an almost imperceptible cavity in such as are extremely depressed, or altogether flat, in which they partake greatly of the character of one valve of a bivalve mollusc. PLRITROTOMA BABTLONICA— a, the canal j 6, the nearly closed umbilica; c, the left or intestinal edge or lip; d, the right or external lip; e, the notch or slit; /, the sinus ; g, the belly; h, the turns or whorls of the spire ; i, the sutures. Linnaeus, of the old, and Lamarck, of the modern school, placed the shell they were about to describe on the opposite extremity to the summit, its only natural position when separated from the animal, but with the aperture fronting the spectator. Modern naturalists, on the contrary, place the shell as it is found on the animal when proceeding on its march, that is, with the spire towards the observer, the summit consequently upwards and behind, and the opposite portion, or the base, as it is generally called, in front and beneath. In this mode of examining a shell, it is clear that the right and left side app.y equally ; but the one so called by Linnaeus is now, by reversing the position of the shell, exactly the contrary of modern authors. The right of the old system is the left of the modern, and vice versa. The terms, inferior siid xttpcrior, in the description of the aperture and its edges, are necessarily replaced by the terms, anterior for the first, and posterior for the second. The apex, or summit, is that part from whence the shell first proceeds, or, more properly, it is the commencement of the spire. This portion may be altogether flat, or very salient, straight or vertical, or directly leaning backward, to the right or to the left, or even forward. It may be pointed, mamillated, entire or carious, and even sometimes hollow, as in the Bulla. Thus the summit is altogether planus, or flat, as in the Chinese limpet ; peracuttts, or very salient, as in the Vermetus ; verticalis or vertical, as in the Patella or limpet, whence Linnaeus has called it (vertex;) narginalis, and sub-marginalis, as in the Crepidula ; rctroversus, depressed backward, as in the Navicella ; aiitcversus, the converse to the latter position, as in certain species of Patella, and, above all, in the Emargiiwla ; sinistralis, or left-handed, as in the Ancylut ; dextralis, as in the Capulus ; acutus, pointed, as in a great number of shells ; mamillaris, mamillated, or rounded, as in the Volutes ; integer, or entire, as in the greater portion of shells ; cariosus, eroded, or carious, as in the Bulinus ihiara ; tnmcattts, or decollatus, as in the truncated Bitlinus, and several other species of turriculated mojluscs ; umbilicatus, utnbilicated, hollowed, sunk in, as with the Ihtlhi and their congeners, as also with certain species of Ammonites and Planorbis, but then the «pex is lateral ; tcrcbratus, pierced, as in the Dentulium. Basis, or the base of a shell, is that part which is usually opposed to the summit, and in which the aperture is formed. Under this name, however, \ve do not understand that which Linntcus and his disciples have designated as the base of a shell ; for in fact, accord- ing to their view, it is the extremity, pointed or not, which is opposite to the summit, and they made it so, because, according to their method of designating the different parts of shells, they placed this one ver- tically, the summit above and the aperture behind. In the present school, the base comprehends all that part which rests more or less obliquely on the back of the animal. Sometimes this base is very large and round, amp/a, rotunda, as in the Trochus, which gives them the form of a reversed one ; sometimes it is parva, small, as in the Tcrebra, Subula, &c. It may be extremely elongated, elongata, as in the Cyprcea, &c. ; and it is formed entirely by the aperture, as in the Pate/la sigaretus ; but many other molluscs more frequently have their base formed by a portion of the last turn of the spire. The direction of the base, which is usually in that of the opening, also offers some considerations deserving notice ; it is altogether perpendicular to the imaginary axis of the shell in the Patella, Solarium, &c. ; it is almost entirely in that of the aperture in the Oliva, Cyprcca, &c. ; in other shells, it is more or less intermediate. That portion of shells termed the body occupies the whole space between the summit and the base. It is most frequently hollow, and not only serves as a covering, but also contains the whole, or a part of the animal's body. 120 CONCHOLOGY Sometimes the name of disc (discus] is given to the base of shells, as in the Haliotldea, but it is then only the last turn of the spire which is comprehended under that name. In a certain number of shells, the body part is not inclined in any direction, either to the left or right, forward or backward, and it is not at all excavated ; the shell is then truly a flat shell, symmetrical in the Sepia, &c., and not symmetrical as in Pate/la Sinensis. It frequently occurs that the base and the summit are united by a portion not curved in any direction, but more or less excavated. These we have already designated as shells covering the body of the animal altogether. This occurs in the Patella, Emarginula, and particularly in the Dentalium ; most frequently, however, the body of the shell is formed by its con- volutions in their various directions, whence they are properly called spirivalve (spirivalvee). To illustrate this familiarly, suppose all univalve shells to be of a conical form, more or less elongated, the Dentalium, for instance, and imagine it flexible ; if this be rolled up, or curved from the posterior part forward, and I'rorn the top to the bottom, positively in the same vertical plane, the result would be a discoid shell, compressed from the right to the left, the summit of which can only be visible in the same direction, and the axis of which is everywhere equally transversal. Such shells may be called rolled up (revolutce). An example strictly in point may be found in the Argonauta and its congeners ; but the Planorbes, though in some respects analogous, are in fact only sub-revolutce. The principal distinctions, and the various modes in which shells are rolled, consist in their greater or less degree of perfection. They are called arched (arcuata) when the shell presents only a slight curve, as in certain species of lielemnite, and as in the Dentalium. Curved (curvata), as in the Ammonocera- tiles, the shell presenting a much more circular curve. Half-coiled (semi^revolttta), when the shell is so curved as that the turns of the spire do not touch, which occurs in the Spirula, presenting a spiral coil on a plane. Coiled (revoluta), when the turns touch each other, as is the case with the true Ammonites (per-revolutcc'), when the spiral turns penetrate each other in such a way that the last conceals all the others ; which is illustrated by the Nautilus. If, on the contrary, the revolutions of the spiral cone are formed tranversely from left to right, as placed on the animal, such shells are termed invo- luted (involute), or, as Linnaeus calls them, convoluted, convoluted. In these species the base is nearly the whole length of the shell, as well as the aperture, and the axis of revolution is necessarily longitudinal. In fact, shells are scarcely ever completely involuted. Those which the nearest approximate that form are the Ovulae and Cyprece. Sometimes the shell does not form a complete turn, as in the Sulla, and then the aperture is as large and as long as the shell itself. The greater proportion of univalve shells are, however, intermediate with the two above-described formations ; that is to say, the body of the shell is the result of an oblique revolution from right to left, and from the lower to the upper part, if we proceed from the bottom to the top ; or, on the contrary, which is more natural, if we view the shell according to its progress of growth. Such are the true spiri-valve, or turbinated shells. The name of spire (clavicula) is given to all that portion of the shell which is formed by the revolution of the spiral cone. Sometimes the last turn of the spire, which is usually the largest, is distinguished by the name of body (corpus) ; the part corresponding with the aperture is the belly (venter) ; that which is opposed to it is the back (dorsuni) : to all the other parts of the shell the term clavicula applies. By far the greater number of molluscs terminate on the right side of the animal ; some, however, which we have pointed out, terminate to the left ; and this circumstance distinguishes the sinister from the dex- tral shells, dextrae and sinistrorsce. Having thus pointed out some of the leading distinctions which characterise the plan of formation presented by shells, we shall briefly enumerate the scientific terms applied to the position of the shell with regard to its inhabitant, leaving the general nomenclature to an alphabetical arrangement. Dorsal (dorsalis) shells are such as are placed on the back of the animal. Of these there are only examples to be met with in the univalves and sub- bivalves ; and in the Chiton among the multivalves. Ventral (ventralis) applies to shells placed beneath the animal's belly. The genus Ombrella may be supposed so situated. Dorso-ventral (dorso-vcntralis) are shells composed of two pieces, the one on the back, the other beneath the belly, as in the Terebratitla, Lingula, &c., and others of the class Palliobranchiata. Bilateral (bilateralis) are those of which the com- ponent parts are, one on the right, and the other on the left of the animal, as in the Ostrea and its con- geners, which occurs in all the class of the Lamelli- branchiata. Perisomatic (perisomatica), when the pieces forming the shell beyond the number of two, surround the body of the animal, as occurs in the Balanus, Anatifa, and their congeners, constituting the class Nenia- topodes. External or internal shells have been so called from anatomical investigation of their position with regard to the animal. External is applied to nearly all shells which cover the skin of the animal, and it is so obvious, that no further explanation is requisite. Internal shells are those in contradistinction to the generality, which are partially covered by some portion of the animal's skin, more or less thick. The shell is then, for the most part, very thin, flat, or only slightly revolved. It is constantly of a pale colour, and does not ever possess an epidermis. No ex- amples of these are found out of the order Poly- thalamacea, or many chambered shells, as also of the single chambered, or Monothalamacea order. Cer- tain species of Mya may also be presumed so situated as to be properly termed internal shells. The terms applicable to the structure of shells depend upon the solidity and arrangement of matter composing them. Thus shells are called solid (solida) when they are heavy and capable of resisting con- siderable violence, such as the Mitres and Olives in univalves, and the Spondylus, Crassatina, Pectina, and other of the bivalves ; fragile (fragilis), when on the contrary. Thick (crassa), generally understood to apply to the valves rather than to the whole shell. Thin, papyraceous (tenuis, papyracea), when the shell is excessively thin. Transparent (translucida), when such thin shells CONCHOLOGY. 121 permit of the rays of light to pass partially through them, as is the case with the Carinaria, Anatina, &c. Lamellar (lamellosa) or foliaceous (foliacea), when the strata of matter are not compact and solid, par- ticularly towards the edge of the shell, as in the Oyster. Fibrous ( fibrosa), when the shell fractures in a per- pendicular direction, from its summit to the base, as in the Pinna. Nudu, or naked, as in shells whose surfaces appear highly varnished : the Olives, Cowries, &c. Corticated (corticata). or epidermata, when the edges (of the stria of increased growth) form on the surface of the shell, an envelope more or less thick, the appearance of which occasions their being distin- guished as furry or scaly. The chemical composition of shells separates the species into such as are sandy (arenacete), in which the calcareous molecules are not united with each other, so that they may easily be reduced to small portions or grains, as in the grey snail. Cretaceous (cretacece) or chalky, when the super- abundance of calcareous matter, renders the shell extremely friable, as in the Tubicola. Horny or membranaceous (membranosce') when, on the contrary, the mucous matter constitutes nearly the whole of their substance, as in the Apfysia. The colours of shells, as of everything else, does not admit of any misunderstanding, and must be ap- plied according to the ideas each one forms of their degree of intensity. They are infinite in their com- binations, though not a very important consideration, as they do not affect any peculiar arrangement ; they may, therefore, be noticed under two heads. Super- ficial (snperficialis] as in shells, externally coloured, as most species are ; or imbued (imbvtui) as in shells, where the colouring matter penetrates the substance, such as the Janthina and others. The system of coloration, or as it is more familiarly termed, the marking of shells, gives rise to the follow- ing generally used distinctions. It is uniform (uni- formis) when equally distributed over the whole surface of the shell ; or variegated (variegala), on the contrary, when the colouring matter is variously ar- ranged, and these differences of marking are called fasctated, ribboned (fasciata], when the zones or bands are of a different colour from the groundwork ; it may be fasciated longitudinally, when they run from the summit to the base, folio wing the direction of the whole of the spire. In bivalves this is distinguished by radiated or rayed (radiata) ; or, if in the direction of the stria', which mark the shell's growth, they are termed transverse (transversalis) ; lineated (lineata) when the coloured bands are closely placed, like hair lines, as in the B ulla physa ; lettered (scripta), when the bands are more or less waved or broken, resem- bling Arabic characters, as occurs in some of the volutes. Tesselated (tettelata), when the system of colouration presents large spots.or other shaped marks, comparable to inlaid marble or mosaic work. When these markings are round, or nearly so, they are called spotted (maculatd), and when the spots are dis- posed in bands, the shell is said to be ribbon-spotted (fascio-macnlata); when the spots are very small, re- sembling rly-marks, they term it dotted (punctata), and fatcio-puttctata, when these minute dots are dis- posed in bands. Of the general form of Univalve and Sub-Bivalve Shells. — In considering the general form of Univalve shells, without paying attention to the distinction of their uarts, certain terms are used which, although rather vague, must necessarily be known. The first distinction regards the equality or inequality of the two sides of a shell of any form whatever, separated by a fictitious axis drawn from the summit to the base, or from one extremity to the other. A symmetrical shell is one whose valves are perfectly equal, and a non-symmetrical shell, such as has its valves unequal, thus the shell of the Argonauta, the Lippet, &c., are symmetrical ; the Sigaretus, and many others, are non- symmetrical. A flat shell (plana,) is that which has no cavity ; tubular (tubulosa), that of which the diameter is con- siderably less than its length, as in the Dentalium ; recovering (aperient), that which is conical, and with- out a spire, properly so called, and so placed on the animal as to be easily taken off, as with the Limpet ; spiral (spiralis], that which is more or less twisted in various fashions, as we shall more fully explain here- after ; but for the moment we will continue to define some terms belonging to the shell examined as a whole. It is called discoid (discoided), when it resem- bles a disc, and which, considering the manner in which the spire is evolved, we call rolled up, as occurs in the Ammonites; depressed (depressd], such as are oval, or rounded very flat, the spire very short, as the Sigaretus. The same name is sometimes employed to designate certain shells whose last whorl, or the body of the shell, enlarged by lateral bands, appears flat- tened from the top to the bottom, as in the Ranella ; globular (globosa or ampullacea), that in which the diameters are nearly equal, occasioned by the great development of the last whorl of the spire, which is much larger than that which preceded it, as in the Ampullaria, &c. ; oval (ovalis), when the longi- tudinal diameter is rather longer than the trans- verse, as in the Cowries, Olives, and many others ; bordered (marginata), when the edges are of a greaer thickness than the rest of the body, as in some species of Cowry, &c. ; navicular (navicularis), some shells which, reversed on the back with the aperture up- wards, have some resemblance to a little boat, as in the Argonauta ; pyriform, when one of the extremities is inflated and rounded, and the other pointed in the form of a short tail, as in the Pyrula. Claviform, club-shaped (clavata), when the body of the shell is short and inflated, and the anterior part narrow and lengthened, as in the Murex haustellum (Linnaeus). Beaked (ro$trata\ when it is terminated at its two extremities by a prolongation of the form of a beak, as in the Ovula birostris (Lamarck). Conical (conica), when one of its enlarged extremities is as if it were cut square, the other being pointed and form- ing the summit; when it is the summit itself of the shell which forms the summit of the cone, it is then called a turbinated shell, as in the Trochus, and the Turbinella ; and it is called conical or conoid, when, on the contrary, the summit of the cone is at the an- terior part of the aperture, as in Cones, properly so called. Cylindrical (cylindrica), when the shell is lengthened, and nearly of the same size throughout, as occurs in most of the involuted shells, such as the Olives, &c. Fusiform, spindle-shaped (fusiformis), such as are swollen in the centre, and pointed more or less at the two extremities, as in the Fiisus. Turriculated (turriculata), those that are very much elongated, that is, whose longitudinal diameter is much greater than the transverse, which depends on the manner in which the spire is formed, as in Turritella. After this short explanation, univalve shells may be considered with regard to the distinction of each of their parts. A con- 122 CONCHOLOGY. ^deration of the different terms applied to the spire, and other parts of univalve shells, would lead into a description of terms generally used in every element- ary treatise on conchology ; but as it would occupy a larger space than can be devoted to the subject in a work of this kind, we will proceed to point out some of the leading characteristics of bivalve shells, as we have already done with the univalves. And here, as with them, we will first of all point out the established position from which the relative terms are taken, which is here figured. Fig. 1. Fig. 2. Fig. 3. Fig. t, a, b, length of the shell; e, d, height; e, lunula, above which is the summit; rf, the ventral or inferior edge. Fig. 2, the line across marks the thickness of bivalves. Fig. 3, a, anterior extremity ; b, posterior; c, d,e,f, muscular impressions; g, lower edge of the left valve. Viewing, therefore, a bivalve shell, composed as it were of one piece, we shall explain that which is un- derstood by long, elongated, cylindrical, transverse, thick, compressed, or very thin. We have already assumed as a point from which we shall invariably depart, that we suppose the shell covering the animal and walking away from the observer (although in fact many of these molluscous animals do not move from the place in which they were born) ; some others, it is true, assume positions in which the head even is down- wards, when the shell would be placed on its edge, in such a way that the summits would be nearly always upwards, and very rarely forward, with the ligament between the summit and the observer. In this posi- tion the part opposed to the summits will be inferior, and the two extremities of the diameter perpendicular to this direction, will be one anterior and the other posterior. Linnaeus, Brugniere, Lamarck, Bosc, and many other naturalists, have described shells alto- gether imagined in an opposite position, that is to My, resting on their summits, the aperture upwards, and the ligament forward. According to this position, the height of a shell will be taken from the vertical dia- meter extending from the summits, or from the liga- ment to the inferior or abdominal edge, supposed to touch the place on which the shell rests ; that is the length with Linnaeus and others. The thickness, (crassitude), will be indicated by the transverse dia- meter of the most inflated part of the two valves, whence the right valve will really be that which cor- responds with the right side of the animal, and the same with the left. We should then name the back of the shell, or the superior margin, that which in fact corresponds with the back of the animal in which or- dinarily the summit is placed, but still more frequently the ligament. The opposite side will be the abdomi- nal side, or inferior margin, that is its real base. In this light Cuvier and others have viewed the position of bivalves, but it is the reverse with Linnaeus, Lamarck, and many other naturalists. The circumference of the shell, or the line which unites the four points just mentioned, forms the margins of the shell ; in this position it would be easy to understand what is meant by a long bivalve, &c. It is long (longa) when the horizontal diameter is much greater than the vertical, as in the Pholas, Mya, &c. ; it is a transverse shell of the Linnaean school. Height(«#a),in a contrary sense, as in the Vulsella. Oval (ovalis), when one of the diameters is but a little longer than the other, as in the Venus. Round (rotundata), when the two diameters are nearly equal, as in the Pectens. Thick (crassa), when the transverse diameter is as great as the others, upon which depends the depth of the valves, as in the Cardium. Compressed, thin, very thin (compre&sa), when this diameter is more or less small in proportion to the others, as in the Tellina. Cylindrical (cylindrica), when the longi- tudinal diameter being very great, the two others are nearly equal, as in some species of the Solen. Navi- cular (navicularis), when the diameter, antero-posterior, being evidently much larger than the two others, the latter are nearly equal, which gives the shell a fancied resemblance to the hull of a ship, particularly when the dorsal margin is straight, as in the Arks. Cordiform, heart-shaped, (cordiformis), when seen from behind, in front, or at the side, it offers some resemblance to the received form of a heart, as in the Isocardia, &c. Triangular (triquetra), when the shell is as if truncated at its anterior extremity, but much more frequently at its posterior, so that a horizontal section, made of the whole shell, would form a triangle, this is illustrated in the Trigoida, Donor, &c. Tongue-shaped (lingui- formis), when it resembles the form of a tongue, as in the Vulsella. Rostrated, beaked (rostrata), when the posterior extremity is much narrower than the anterior, as in several species of Tellens. Truncated (truncata), when it is, positively, as if one of its extremities were cut off, as in several species of Donor. Eared (aun- culata), when the margins of the shell, towards the summit, are more or less dilated into certain portions, termed ears. Inauriculated, when only one of these appendages occurs. These ears are equal, or unequal, when of the same size, or differing from each other in size ; they are spiny, when their inferior margin appears toothed ; obliterated, when they are but slightly angular, as in the Lima. The valves may be regular or irregular ; they are regular when they present an uniform shape, totally independent of all exterior bodies, as is the case with CONCHOLOGY. 123 most bivalve shells ; on the contrary, the valves are irregular when they assume the shape of the substance to which they adhere, such as the oysters — Anomia, &c. This occurs with both valves in some instances, as the form of the upper is necessarily modified by that of the lower valve : whether the valves are thick or thin, is so obvious, that no particular term is necessary. The valves are plaited (uiflexa), when they form an angle or fold projecting a*, their inferior part, as in the Tellens. Each valve, regular or otherwise, may really be compared to an univalve shell, in general very flat and covering the animal, but instead of being placed on the back of the animal is situated at its $ides ; there must, therefore, exist a summit and a base, an external convex, and a concave internal surface. The summit of a bivalve shell is termed the beak, or tip (apex), and it is from that point the growth of the shell commences. Considering its general position, always bearing in mind the animal which it cover*, it is oral or buccal (oralis), when it is at the anterior extremity of the valve, which is rarely the case ; an exam pie, however,is exhibited in thespondylus, oyster, &c., and this is commonly called the spur or heel. It is dorsal (dorsalis), when it corresponds with the back of the animal or the superior margin of the shell, which is ordinarily the case with shells in general ; in this case it may be antero-dorsal, when placed more forward than backward in the length of the valve ; mediii-dorsaL, when in the middle ; and postcro-dorsal, when mure backward than forward ; anal or posterior when situated at the opposite extremity to the mouth, as in the Terebratula, Lingula, &c. It is also from the relative position of the summit of the bivalve shells, that the characters are indicated by equilateral, sub-equilateral, or in-equilateral. A valve is said to be equilateral when the cephalic sum- mit is exactly in the middle of the side on which itis placed, so that a perpendicular line drawn through would sub-divide it in equal portions, as is seen in the Pfctcns. Sub-equilateral, when there is only a slight difference in its position, either backward or forward, In-equilateral, when the difference between the two sides is more considerable, and consequently the summit becomes either antero-dorsal or postero-dorsal. The direction of the summit offers also some character designated by particular terms ; it is the most frequently a little curved or inclined forward, but it is also some- times entirely vertical, or in the direction of the diameter of which it forms one extremity, and it i more rarely inclined backward ; and in some species the summit has a tendency to assume a spiral form, as in univalves. It is variously named in scientific terms according to its being — ear-shaped, spiral, recurved entire, callous, &c., for which, as before, we refer to the treatises on this subject. The external face of the valves offers several characters important to know, it is either convex or flat, which needs no explanation it is full (plena), as in the Tridacna ; bordered (mar- ginata), when furnished with a projecting rim ; toothec or serrated (dentata), when the circumference is furnished with what may be here termed teeth, as in the tridacna, cordiform, crescent-shaped, lanceolate oval, oblong, superficial, &c., according to its resem- blance to a heart, as in some of the species of Venus, The internal surface of the valves presents also many characters deserving attentive consideration, but not easily described without illustrations, that would here occupy too great a space. The valves are right hanc or left, according to the position of the animal as we lave already placed it ; they are equivalve,when exact- y corresponding in size, depth, and general form, as exists in most of the bivalves ; sub-equivalve, when he difference between the two valves is not very con- siderable, as in certain species ofPcctens; in-equivalve, when there is a very visible difference, either in the ibrm, size, or other particulars. Linnaeus has named ;he smallest and flattest valve the operculated one, as m the Gryphcea; but, for the reasons we have stated, it is mis-applied. The valves of bivalve shells, placed in opposition to each other, often touch at every point of their circumference, in which case they are termed closed (clausa), when not thus everywhere united, they are said to gape (hians). In the first instance, the closing of the valves may be simple by approximation, or they may be shut by the insertion of the opposite notches, grooves, teeth, &c., with which many are furnished. In bivalves having a partial opening in the circumference of the valves, more or less considerable, it is, for the most part, only posterior, or both anterior and posterior to a certain extent, as in the Solens, the Pliolas, and many other species ; sometimes it is inferior, and more or less anterior or medial, as in the Arks, Muscles, &c., and it is some- times anterior, and superior, as in the young examples of the Tridacna. Another point ot view, perhaps more important than most of those which we have described, is the peculiar mode in which the valves of shells are united to each other ; these are three in number, one belongs exclusively to the animal, depending upon the use of certain muscles or bundles of muscular and elastic fibres, which are carried trans- versely from one valve to the other ; these leave an impression on the internal surface of the valve, the study of which has been pointed out as important in deciding the genus of a mollusc, without any previous knowledge of the animal. The second mode of union also belongs properly to the animal alone, and although much less than the first, it leaves also its indices, or traces, very perceptible in the excavations of different forms in which it is attached, this is named the ligament (ligamentum) ; it consists of a mass, more or less considerable, of horny fibres, elastic, and covered with an epidermis, carried from side to side of the valves. Some bivalve shells are met with entirely without a ligament, properly so called, as in the Orbicula, Pholas, and others, in which it is not distinct from the general epidermis, as in the Pinna, but most frequently bivalves possess a liga- ment ; this is simple (simplex) when there is only one, as in the Venus ; and the greater number of bivalves, double (duplex), when there are two ligamental pro- cesses, the one posterior, as in certain Tellens, w hence they are called amphidesma, or when there exists one external, the other internal, as in the Mactra. Mul- tiple (multiplex), when there is a series more or less considerable, as in the Perna, and, perhaps, even in an inverse position, in the Arks. The position of the ligament, with regard to the summits, is thus defined : anterior, when placed in front of them as in the Donax; medial, when immediately beneath the apices ; posterior, which is the most usual, when behind the summit ; antero-posterior, when both backward and forward, occupying an extended space, as in the Arks and their congeners. The position of the ligament, as it is externally visible or not, distinguishes it into external (externum), when visible, which occurs with most bivalves ; deep (profundum), when it is so deeply placed, that it is scarcely perceptible on the outside; 124 CONCHOLOGY. as in the Venus, zig-zag ; internal, when it is positively altogether concealed, as in the Mactra, Crassalclln, and to a certain extent in the oyster. As to its being flat, round, short, long, &c., it speaks for itself. The last mode of connexion between the valves of shells is called the hinge (cardo), which may be de- fined as a particular arrangement of differently formed prominences, or cavities on each valve corresponding reciprocally with each other. Authors call that the thickest portion of the circumference of the valve in which most frequently these cavities or teeth are situated ; this is the cardinal margin (margo cardinalis) ; the cardinal blade or ridge (disscpimentum cardinalis) is that portion of the edge which exhibits the teeth. Examining shells with regard to this arrangement, they are called toothless (acardis) when no trace exists of cavities, projections, or ligament, but of these, perhaps, only one example can be offered, it is the Lingula, When there is only one protuberance on the part termed the hinge, more or less elongated and irregular, it is called callus (callosa). When the cardinal ledge, instead of being vertically placed, as is in most instances the case, is horizontally enlarged by a projection fitting into a corresponding cavity, placed beneath the summit of the other valve, or under a similar projection, Linnaeus called it dens vacuus or depressns ; but erroneously, not being a true tooth, and only serving for the insertion of the liga- ment. In all other shells provided with a true hinge, it is necessary to observe if it is exactly similar on each valve, in the first instance, it is termed therefore similar (similis), and in the second dissimilar. The position of the hinge, generally considered, also re- quires some particular denominations, which are nearly the same as applied to the summits ; oval, dorsal, anal, &c., as they may be situated on the back, posterior, anterior, &c. In the different portions of the hinge it is formed complete by means of eminences and cavities, the one called teeth, the other indentations (fossula) ; when the hinge is formed by one tooth or protuberant portion, as in the Mya, it is called the Sinus by Linnaeus. These eminences or correspond- ing cavities with relation to the summit may generally be denominated in the same manner as the entire hinge. The cardinal teeth (denies cardinales) are those placed immediately beneath the summits, and are usually the principal ones. The lateral teeth (denies laterales) are, on the contrary, those of less importance, and more or less separated either before or behind the summit ; those placed nearest to the lamella are called dens anticus; and the dens posticiis are those on the side of the ligament or shield, thus reversing the Linnaean position. The direction in which these teeth are placed distinguishes them into vertical, ob- lique, longitudinal, divergent, or convergent. In the Lyrena they are nearly vertical, oblique in the Venus, longitudinal in the Cardita, divergent or convergent, according to the point of view taken from the summit, as in the Mactra. The mode of junction of these teeth establishes the terms inserted (intrans}, which is where one penetrates between two others. Alter- nate (alternus), that which crosses another obliquely, as in the Cardium; articulated (inscrtus), when the hinge formed by them is produced from a reciprocal arrangement inverse on each valve, as exists in the greater number of bivalves. The particular form of the teeth is expressed by lamellar (lamellosa) or lon- gitudinal when they are very long ; and much com- pressed if short or thick ; when on the contrary, straight or curved, simple or bifid, smooth or striated, accord- ing to circumstances, too obvious to need further explanation. The number of teeth is sometimes important to observe, though they are not always uniform in the same species of molluscs. In multi- valve shells, according to the modern system of clas- sification, such as were included by Linnaeus from being more or less complete tubes, which might accompany or even entirely envelope the two valves of a bivalve mollusc, were by him sometimes called accessory pieces, have been excluded, and only those completely visible are so called. Multivalve shells are constantly produced by animals which may be called intermediate between the mollusca and the entomozoria, while those of the Pholas, Teredo, &c., are true malacozoaria. They are also very few in number, and it is scarcely necessary to dwell particularly on the denominations of their parts, as the greater portion of them are the same as those of bivalve shells ; they may be called with regard to the position of their parts or valves, articulated, lateral, ante or post lateral, dorsal or ven- tral, but one group established by Lamarck, under the name of coronal or sub-coronal molluscs, requires a more particular notice. In these the portions consti- tuting the shell being disposed regularly round a com- mon axis, are firmly knit together by their margins, so as to form a complete cavity or space in the centre, closed or open inferiorly, and shut superiorly, by a small number of pieces of various forms, the total of which is called their operculum, or lid ; the form and number of principal pieces, as well as those thus termed the operculum, varies so much that they merit distinct terms to designate them. The support (basis) is always monotomous, and may be simply membran- ous, irregular, or patelliform, in which case it may easily be confounded with the Limpet. The terminal or operculated portion is at least ditomous, because it is always in pairs and symmetrical, but then each lateral piece is most frequently divided into two valves, the one dorsal, the other ventral, according as they correspond to the analogous coronal pieces. This operculum is called articulated, when it evidently touches the coronal portion ; it is inarticulated when entirely surrounded by the membranous portion of the aperture. The principal portions of these shells have occasioned their being called coronal, because they form a sort of crown round the body of the ani- mal. The number of pieces forming what is termed the operculum usually amount to six, but they vary much sometimes, being only four in the usual state of these valves ; each is divided on its surface into two triangular areas, the one in relief, the other hollow. And in the interior of these it is found that they are doubled in their superior or anal half by a vertical plate or separation, the extent and form of which is very important in distinguishing this singular species of shell. A reference to the article Balanus will also point out some other peculiarities not yet satisfactorily explained. Upon this subject, as well as many others connected intimately with the study of the science of conchology, we have been constantly tempted to en- large ; but a want of space must preclude us from dwelling longer, as a volume might be written, filled with ingenious hypotheses, and well-grounded deduc- tions ; our object, as has been more than once stated, being to induce a deeper research in others, raihor, than to broach our own opinions, or to write a volumin- ous treatise on the subject. So numerous are the pub- CONCHOLOGY. 125 Hcations adapted to every stage of the study, that those who have leisure to pursue it may take it up in any part of its progress. We flatter ourselves that we have, as concisely as the nature of science will admit, given an outline likely to prove serviceable to the student, without entering abstrusely into that portion of it which can only be interesting to the more finish- ed naturalist. Having, in this place, confined our- selves more particularly to shells, as objects detached from their parents, much more remains to be said of them as properly connected with the animals; and this will be attempted under the articles MOLLUSCA and MALACOLOGY. We will now proceed to give a rapid sketch of the history of the science, or at least that part of it which includes the arrangement of shells alone, without any or very little reference to the animals. In which point of view, nearly all the naturalists of former times have written, and it may not be found useless or uninteresting to name the most celebrated authors, beginning from a very remote period of time down to that at which the science has assumed a new and higher order of claim to the attention of man- kind. That the study of natural history, and Conchology as a part of it, was not deemed beneath the notice of philosophers and statesmen in the enlightened ages of Greece and Rome, is proved by the valuable works still extant, the earliest of which is that of Aristotle, who flourished 322 years before the birth of Christ. It may be deemed a precious monument of accurate observation, and justly entitles him to the immortal name of the father of natural history. Like every other of his writings, this branch exhibits profound wisdom, and, even to the present day, his outlines of a systematic arrangement have been fol- lowed, and many of the genera of shells retained by succeeding authors. He first established the two great natural orders of univalves and bivalves, viewing shells, precisely as they are now considered, to be testaceous bodies, consisting of so many pieces or parts. The first were therefore termed Monothyra, the second Dithyra. To these he added a third order, in which were included the turbinated shells. Of these three orders he commenced a generic arrangement, dis- tinguishing between their terrestrial or aquatic habitats, and even the immobility or locomotive power of the different species. These he separated into the ciiietica or acineta. When we consider the period at which this great man existed, and the isolated nature of his labours, comparing them with I the information he possessed in natural history, we may be truly astonished at his sagacity and wisdom. Though the acquirement of human knowledge is slow and progressive, Aristotle's Ostracodermata pre- sents a valuable scheme of shells, and the sound well defined basis of all subsequent systems. Nor was the Macedonian philosopher the only great man of anti- quity whose mind was alive to the study of natural listory, and whose more important labours were liversified by its inviting charms. Pliny, -(Elian, A.theniuus, and Cicero, were each of them enthusiastic laturalists, and have left valuable proofs of their iccurate observation of nature's productions, particu- arly in that branch we are now treating of. But this I tudy, like all other liberal pursuits, was neglected in he darker era that succeeded, at least no evidence o the contrary has survived to this period ; but in fter ages, when the mists of Gothic ignorance, which lad so long obscured the western horizon, dispersed, the light of science dawned, and Conchology not only revived, but was encouraged by men eminent "or learning and a superiority of mental acquirement, the admiration and envy of past centuries. Pliny, who lived in times more favourable to the cultivation of science (A.D. 80.), added but little to the informa- tion he derived from the writings of Aristotle. He certainly has added considerably to the number of species at that period described. The shores of the Roman empire, the Mediterranean, and Red Sea, presenting a rich field for the enterprising concholo- jist, he described, with great fidelity, the form and external aspect of shells, in which he has been followed by succeeding naturalists. But his arrange- ment was unphilosophical — his descriptions unsatis- factory— and he discovered but little matter import- ant to the science beyond that which had long before been pointed out by Aristotle. Passing over the dark ages succeeding Roman greatness, in which science was degraded and ignorance deified, we find, to the end of the fifteenth century, little to instruct or interest us on this subject. Vicentius, in 1494, treats of the genera Murex, Ostrea, and some S'dices, but without any systematic arrangement ; and he has done no more than borrow from his pre- decessors, adding most largely from the superstitious absurdities of his days. In the sixteenth century, Belen, Rondeletius, and other authors, added some- thing more to the information transmitted from the earlier ages. Their works, however, merely described new species, or pointed out what they considered a more natural arrangement of shells, many of them, however, venturing upon a general systematic classi- fication materially different from the first outline sketched by Aristotle. We will therefore come to that period when Daniel Major may be considered as the first author who really occupied himself with a distribution of shells into a systematic form. This will be found in an Appendix to a Treatise on the Genus Purpura, by F. Columna, in the German language, under the title of Ostracologia in Ordinem Redactn, printed at Kiel in 1675. This appendix contains synoptic tables pointing out a natural asso- ciation of genera established on the species observed by Columna, and consequently very few in number. To Major we are indebted for the division of uni- valves and multivalves, among which he places the bivalves. In 1681, our countryman, Grew, in his Museum llegium, a descriptive catalogue of the Royal Society's collection, has published a systematic and synoptic table of the genera of shells, in which he includes all the testaceous envelopes of animals, and, without posi- tively employing the present received terms of the science, established divisions of the single, double, and multiple shells, corresponding with our univalve, bivalve, and multivalve genera. In the first, he separates such as are rolled on a fictitious axis from those not so constructed ; these are again divided into the species whose spires are visible or not, as in the Nautilus, Cowry, &c. By this arrangement it is obvious that Grew distinctly pointed out those clear indications of animal structure forming the greater number of our present genera. Sibbald, in 1684, in his Scotia Illustrata, goes back nearly to the divisions of Aristotle, principally con- sidering the habitat of the shells, dividing them into terrestrial and aquatic, and the latter into marine and fluviatile species. 126 CONCHOLOGY. Lister, in 1685, still followed a similar arrange- ment ; but, having the advantage of examining a far greater number of shells, his treatise is conse- quently more complete. His work, Historue sive Synopsis Methodica Conchyliorum libri quatuor, ap- peared in parts, and continued down to 1688. It contains, besides, a great number of plates, faithfully drawn and engraved b)' his daughters, the intro. duction of a distinction between the equality or inequality of the valves. He also appears the first to have attached a proper importance to the con- sideration of the hinges of bivalves. Tournefort, an eminent French botanist, who died in I 708, attempted to facilitate the study of shells, which he designated under the general name of Testacea, defining them as the envelopes of certain animals possessing the hardness of a tile, or baked earthen vessel ; but his method was only known for the first time by a work of Gualtier's, published in 1748. Tournefort substituted the names of Monotonia, Ditama, and Polytoma, for those of the present day. Among the Monotonies he established the distinction between the univalves, properly so called, and the spirivalves and fistulivalves, and his generic charac- ters are considerably guided by the form of the aperture. In his class Ditoma he is said to have been the first to establish a division between the bivalves that closed perfectly (Clausa) and those which partially gaped (Hiantes). He also paid atten- tion to the position of the hinge. In his Polytoma he, however, confounds the Echini and Balani, Rumphius, in 171 1, described a considerable num- ber of shells from the Indian seas, but he did not add much to the science of Conchology. He did not even separate the bivalves from the multivalves ; and with respect to the univalves, he considered them simple or turbinated, as distinguished by Aristotle. He, nevertheless, indicated some well-defined divisions, such as the Strombus, Foluta,and the porcelanic genera. Lang, in 1722, proposed a new but partial con- chological distribution, merely treating of marine shells ; but notwithstanding the pompous enuncia- tion of his work, which is too long to be here inserted, he added very little to Lister's arrangement beyond examining the equality or inequality of the valves, arid the relative positions of the summits. He also paid rather more attention to the form of the apertures in univalves, and of the summits of bivalves, in these he likewise established a division of anoma- lous species. J. Ernest Hebenstreit, in 1791, published a disser- tation, entitled, De ordinibus Conckyfiorum Methodica Ratione instituendls, in which there are but few impor- tant novelties. He, nevertheless, among the univalves, pays more attention to the spine than his predeces- sors had done ; and in the bivalves, his first division is characterised by the presence or the absence of the hinge, as then considered. Phillip Breyn, in 1830, first drew the attention of conchologists to a distinctive character of shells, up to that period overlooked, this was the number of cells or separations in univalves, whence proceed the names polythalamia and monothalamia. Gualtieri, an Italian author, in 1742, published a work which still possesses some degree of reputation, from the great number of shells figured. They are, however, but indifferently executed, and fall far short of modern illustrations. As a work of scientific refer- ence, it includes all, or nearly so, that his predeces- sors had introduced in the way of classification, with- out adding much improvement or novelty; we shall not, therefore, dwell upon it, but merely observe, that though he indicates many generic divisions, they are not established on a solid basis, and have afforded but little to guide subsequent writers. D'Argenville, in the same year, published in France the first edition of his work, De rH'istoirc Naturellc eclairde dans Deux de ces Parties Principales, la Litho- logie et la Conchyliologie, a work like that of Gualtieri's, much admired for its plates, but containing little scien- tific improvement to recommend it. In nearly all he has done, Lister's system was his guide, and when he ceased to consult or follow that authority, he has invariably made matters more obscure, though he is most unjustly critical in his observations on that author. Klein, immediately after D'Argenville, published a work entirely systematic, but without the advantage of good illustrations. His object appears to have been that of overturning and changing all Linnams attempt- ed to establish ; this being unsupported by the reasons of subsequent writers, render his work a mass of confu- sion and little worthy of reference. He certainly pro- posed, rather than established, a great number of genera since adopted ; but the characters assigned to them were so vague, and so badly circumscribed, that his writings have nearly fallen into oblivion. His clas- sification of the Echini, however, merits praise as being the first attempt, though extremely deficient in exe- cution. Adanson, in 1757, published his voyage to Sene- gal, and, although the first editions of Linnaeus' Sys- tema Naturee had already appeared, we place his information in a point of priority, because it appears quite evident that great naturalist must have derived a considerable portion of his general fixed principles of conchology from Adanson ; he also may, more properly, be considered a writer on malacology, since he examines shells, with their animal architects. By this much innovation was introduced into the science of conchology, properly or abstractedly so called in this article. Thus, besides an elaborate study of each of the parts of shells, and a description of the charac- ters, he may be said to have formed a distinct system for each. Among other novelties in conf.rmation of this he divides bivalve shells according to the number of their muscles, or their attachments ; and above all, he has introduced the consideration of the operculum, an important feature of the science, up to his time alto- gether neglected, or nearly so, by subsequent authors. From this consideration, he established in the Helices two marked sections : the first, univalve snails ; the second, operculated species, which he considered, though very erroneously, as forming the gradation to bivalves. He appears also to have been the first who classed the Patella, with the Chiton, his section of mul- ti valve conchs containing only the Pholas and the Teredo. Linnaeus, in his first edition of the Systema Naturee, proved that he was not master of this part of natural history ; but in the edition following Adanson's work, he exhibited the possibility of applying the same principles which he had discovered and so advanta- geously employed in botany. He, nevertheless.created no very novel consideration in the first divisions; nor, indeed, in the secondary ones, since he divides shells into multivalves, with which he begins, and in which he places the Chiton; bivalves and univalves, after- CONCHOLOGY. wards sub-divided into turbinated or not turbinated ; but he has the lasting merit of having introduced, in the description of their characters, in their circumscrip- tion, and in the creation of a conchological language, that brevity and clearness which will ever entitle him to be considered the model and master of systematic naturalists, from which nothing can obviously detract, except the bad taste and unaccountable feeling which but too frequently marks his nomenclature — setting modesty at defiance, and making greybeards blush. About this period Martini commenced his gigantic book, which was continued and completed by Chem- nitz in 1788. This we consider rather as a collection of the figures of shells, than as a true system of con- chology, the arrangement partaking of Gesner and Lister's plans, with regard to the first divisions ; and the others formed from the habitat of the animals, he nearly follows the Linna:an system, and his great divisions may be considered simple, and not breaking their natural gradations in any very remarkable de- gree. As a work containing a greater number, and, generally speaking, more correctly drawn illustrations of shells, nothing combining these united advantages has ever yet appeared ; its great price, however, will ever render it a work of luxury more than utility. Dacosta, in 1776, published an original, and, it may be said, true system, under the title of Elements of Conchology. It differs evidently but little from that of Linnaeus, though he attaches more importance to the predominant characters drawn from the form of the aperture in turbinated univalves, and the hinge of bivalves ; he is the first writer who suggested the pro- priety of changing many of those terms used by Lin- naaus, of which we have already pointed out the inde- cency; he has also considerably augmented the number of genera of that naturalist, each of which are illustrat- ed by tolerable figures ; but though his work may be deemed highly instructive, he has not introduced into the science any very strikingly new consideration. We pass over in silence several authors, such as Mu'ller, Born, and others, who have added little or nothing to the science of conchology, in our present view of it. Those of them who have examined shells with reference to the animal, will be noticed hereafter, and we then come to the French School of Concho- logy, in which it appears to us more has been done than in any other, towards raising the study of this interesting portion of creation into its well-merited rank of natural sciences ; and we must be permitted a slight digression from the immediate article under consideration, to state, that although we are not wed- ded to the system of any one author, blind to the faults of all, or insensible to the improvements of time, we must, nevertheless, adopt some rule of conduct, some guide for our opinions, and we do not hesitate in preferring a system, matured as it now is upon the admirable model furnished by Cuvier, and other great naturalists, his disciples: like every human effort it is incomplete, often erroneous, but as a whole, the most perfect yet constructed ; and, from being founded on the broad basis of truth and common sense, will last to the end of time, becoming more confirmed by every day's experience of its correctness. Brugniere, in 1792, is the first author we shall name, as having taken the lead in forming the modern science of Conchology. We must all along be under- stood to allude to it, more particularly as relative to the consideration of shells as isolated bodies, the view we have confined ourselves to in this article. Brugniere closely followed Linnceus, but it is dm; to him to acknowledge that he has much more clearly characterised and circumscribed the genera, which has necessarily led to considerable increase of their number. Death having deprived the world of the benefit that would have resulted from his labours early in the commencement of his scientific career, the small number of genera he lived to describe will prove the justness of his reasoning. His characters were well defined, clearly explained, and, what is extremely im- portant in this as well as every other study, they are perfectly consistent with each other. He may be con- sidered the first naturalist who has introduced into conchology that exact precision of detail so necessary to be observed, particularly with reference to those minute indications required in a comparison between recent and fossil shells ; in other respects he does not claim much praise as having introduced any very marked improvement in the Linngean system. De Lamarck improved upon his friend Brugniere's method considerably, not only by considering the shell as a part of the animal constructing it, according to the opinions of Guettard, Adanson, Geoffrey, Miiller, Poll, Cuvier, De Ferussac (father and son), De Blain- ville, and others, but by the great number of new generic divisions, a more rigorous terminology ; and by the introduction of the muscular impressions in bivalve shells, as the base of one of their prin- cipal divisions, which, in 1810, was adopted by Ocken. Lamarck, nevertheless, fell into the error of classing the Chiton with the Patella. In general it may be observed that he has entirely departed from the divisions of previous conchologists, established upon the number of pieces composing the shell ; and that it is rather the combined form of the shell which he examines, to establish his four first divisions into sub-spiral, cardiniferous, sub-coronal, and vermicular ; and, in fact, he could no longer admit the univalves, bivalves, and multivalves, since he places the Chiton amongst the sub-spirals, which certainly no one wishing to arrange a collection of shells would have thought of. In this arrangement, Lamarck has, if possible, placed shells too closely in scientific connexion with their animal inhabitant, which, though it renders the subject far more interesting to the philosopher and anatomist, occasions the science to become more dif- ficult to those who have the same motive for studying it, and merely look at it as a mental relaxation from other worldly pursuits. During the period that was occupied, in bringing to perfection and publishing Lamarck's system, other conchologists followed Bru- gniere's extended view of the Linnsean system, and Donovan, Montagu, Bosc, &c., published their arrange- ments. Denys de Montfort, in 1808, brought before the public his Systematic Conchology, including only the univalve shells ; but he carried his generic subdivisions to a ridiculous excess, by wishing too narrowly to define extremely minute characters ; this, doubtless, arose from his having been the first author who thought science demanded the description of microscopic shells ; but though his work, were it generally useful, might easily be modified, it is not considered an authority at this time. Many of his genera are, nevertheless, adopted. De Blainville, a French naturalist, and an excellent anatomist of Cuvier's school, published his first clas- sification of shells in a memoir read at the Philomatic Society in 1812. This was founded on a reference to 128 C O N D Y L U R A. the animals, and not their simple coverings; but he has the merit of having, for the first time, introduced a consideration of shells in a new point of view, that of forming the essential protection of the organs of respiration, from whence followed, to a certain extent, the general form and position of them ; and thus, by combining as it were the double function of the shell and the animal, to be able to pass easily from the one to the other, by calling the attention to the indi- cations of a new character, founded on the symmetry or non-symmetry of univalve shells, with regard to the respiratory organs. He also replaced the Chiton with the univalves, and in many other instances has ad- duced very satisfactory reasons for having re-united many of the genera of Lamarck and other naturalists, improperly and needlessly sub-divided by them. This brief sketch of the progress of conchological study, as a science, must be considered extremely in- complete, since we have professedly named only a small portion of the labourers in that field, and only such .as have in some degree attempted a new system- atic arrangement of shells alone: to have enumerated each new idea, each novel alteration in the progress of time since the days of Aristotle, would have occu- pied space allotted to more interesting matter, and could not have conveyed any useful information, par- ticularly to the scholar ; to have given a mere catalogue of authors, and the various views they have taken on the subject, for the same reason is useless, and as Con- chology in future must be combined with a reference to the animals constructing shells, the system will be described moreamply under the article MALACOLOGY. The object of this work is to point out briefly all that may be deemed solid information on every branch of natural history, and not to enter into controversial points of opinion, or to wage war against those with whom we may have the misfortune to differ. Every man has, doubtless, a right to his own set of ideas, but it is deeply to be regretted, when his ignorance, or its offspring, vanity, induces him to question with acrimony another's different view of the same subject ; to split hairs with cannon balls, and to write all men down as asses, who presume to differ with him in opinion. This, unhappily, but too frequently is exhibited by modern naturalists, and it is the more remarkable, since the study of natural history should lead to every good feeling of human nature — unite mankind in one common cause, and contribute to one great end — that of adoring the Author of all these marvellous produc- tions ; the least of which, if properly received, would humble the pride of the most arrogant of mortals ; by proving to him, that the ingenuity of ages can only produce clumsy imitations of anything bearing the imprint of Almighty wisdom. CONDYLURA. A genus of mammalia, belong- ing to the insectivorous division of the order Car- nassier, and, in general habits, bearing some resem- blance to the moles, but differing from them in many particulars. The most, striking of the external pecu- liarities is their tail, from the appearance of which the genus has obtained its name. It is formed with a series of nodes or enlarged round protuberances (condyles], which give it some resemblance to a neck- lace of beads. The characters are : six incisive teeth in the upper jaw, of which the two in the middle are very large, bent into a sort of spoon-shape on their inner sides, and with their cutting edges a little oblique ; the two external incisors, in this jaw, are conical, and bear some resemblance to canines. There are four incisors in the under jaw, which project forward with a curve, and give a sort of spoon-shape to the exterior part of that jaw ; also, to each side of the upper jaw there are three false molars formed, each of two plates of enamel, and having pointed tubercles on their inner edges, and a groove on their outer. There are four false molars in each side of the lower jaw. The canines in the upper jaw are large and strong for the size of the animal, but those in the lower are very small. They have no appearance of external ears, and their eyes are remarkably small ; their fore-feet are short and broad, with five toes upon each, furnished with claws well adapted for digging in the ground. The hind-feet, which are longer and more slender, are also each provided with four toes. This genus of animals is understood to be peculiar to North America, and in its habits to bear a very considerable resemblance to the moles of the eastern world, that is to say, they spend the greater part of their time under ground, and are understood to sub- sist chiefly upon earth worms, earth insects, and larva. Two or three species have been mentioned, but only one is known with certainty, and of its manners we know but little. Star-nosed Condi/lure (Condyhtra cristata). This is the Sorex cristatus of Linnaeus, but it is more nearly allied to the moles than to the shrews, and therefore, the name is inapplicable. The knots on the tail and also the very remarkable form of the termination of the muzzle, readily distinguishes this from any other animal. The muzzle is very long, supported in the centre by an axis of bone, in the same manner as the snout of a pig, and like that, it has the nostrils central in the extremity, so that we may conclude that its sense of smelling is of considerable service to it in the finding of its food ; but the extremity of the snout is very different from that of any other animal. It is in the form of a star, consisting of cartilaginous rays which are rose-coloured, have their surfaces granu- lated, and are about twenty in number ; two on the middle of the upper part and four on the under, are much longer than the rest. All the points of which this star-like rose is composed, are moveable at the pleasure of the animal ; but from the peculiarity of their form, we may naturally suppose, that this description of digging instrument, though it may make its way faster than the entire snouts of other digging animals, cannot force its way so readily through compact mould, and thus, the animal is adapted to those alluvial deposits in the American forests, which are formed rapidly, consist in great part of leaves, and are very spongy in their texture. It is possible that some of the elongated filaments may assist the animal in feeling for its food under- ground : but we are not so well informed of its habits as to be able to decide upon particulars. The feet bear some resemblance to small hands, they are broad, naked, and covered with scales ; and the'nails, though longer than those of the mole, are more slender and not so trenchant on their under sides, which farther shows that this animal is adapted for making its way through softer soil than that with which our moles have to contend. This is still farther indicated by the structure of the hind feet, which are long and slender, differing in form from those of most other of the smaller burrowing animals, whether of Europe or any other part of the world. All the phalanges of the hind toes are free, so that the sole of CONDOR—CONIFERS. 129 these leet consists of the metatarsal bones only. This structure of foot enables the animal to spread out its hind toes till they are as wide apart from each other as those of a free-toed bird ; but whether the animal uses the extensive resistance which it can obtain by this means, in pushing through soft earth or through tangled vegetables, has not been ascertained. The tail is remarkable i'or having transverse folds of the skin, corresponding to the different vertebrae, and in the intervals, between those folds, there are long hairs more thinly set than in any other part of the body. The colouring of the fur upon the body is nearly the same as that of the common mole, and it is glossy, and difficult to be soiled or wetted while the animal is alive ; but its texture is not so delicate as that of the fur of the European mole. The whiskers do not spread out to the sides as in most small animals, but project forward. On the feet there is a large mem- branous scale on the inner surface, and a few scattered hairs on the outer. In its general form this animal indicates more activity in motion, though probably less strength in proportion than the mole ; but its manners are so imperfectly known, that no very good account of its economy can be obtained. It is not large, being about four inches long in the body, and with a tail about half that length. Condylura longicaudata. This species is still less known than the former; it inhabits the northern parts of America, but whether exactly the same kind of places as the other is not said. It is without the nasal crest; the tail is rather longer than half the body ; the fore feet are similarly formed to those of the moles, but the hind feet are long and slender. The feet are scaly, thus indicating a digger in the ground, an inhabitant of watery places, or both. The time of pairing, the period of gestation, the number of young, the state in which they first appear, the length of time that they are suckled, their age at maturity, the length of their lives, and all of what may be termed their domestic history, is entirely unknown ; neither are we able to tell, with any certainty, what is their principal function, or the importance of that function in the general economy of nature. CONDOR. See VULTURE. CONIA (Blainville), Asemus (Ranz), a genus of mollusc, separated from the family balanides in con- sequence of a particular combination of the number of pieces forming the tube. The shell is conical, de- pressed, the coronary part formed of four pieces only, more or less distinct, nearly equal, and usually striated from the summit to the base, with or without distinct areas. The support is flat, very thin, or altogether membranous. The operculum articulated, pyramidal, composed, as in the balani, of two pieces on each side, moveable, or as it were soldered to each other. The genus has been subdivided into the species whose valves are pectiniform, with the areas and the divisions very distinctly marked. The second divi- sion includes all those in which the valves are but little or not at all distinct, and without any traces of areas. The animal is precisely the same as that of the balanus. CONIFERJE. The fir family. A natural order of dicotyledonous plants, containing twenty or thirty genera, and nearly two hundred known species. Considerable discrepancy of opinion existed for a long time among botanists in regard to the structure of the conifers; ; but the researches of Richard and Brown have dispelled all difficulty on the subject, NAT. HIST. — VOL. II. and have enabled us to comprehend fully the organi- sation of this most interesting family. The order oc- cupies a place intermediate between the cellular and vascular plants. To the former it is connected by means of Lycopodiaceae, with which it agrees in the aspect of the stem and leaves, and in the nearly total absence of spiral vessels ; while it is connected with the latter through the intervention of the oak, willow, and birch tribes, with which it agrees in having an amen- taceous inflorescence. It bears a very strong affinity to Cycadccc, resembling this family in the form of its naked ovula, in its mode of inflorescence, in the ar- rangement of the veins of the leaves, in the imperfect formation of the spiral vessels, and in having the vessels of the wood perforated by numerous holes. The name Coniferce is derived from the fruit, which is in the form of a cone. The essential characters of the order are : Flowers, monoecious or dioecious : Sterile flowers, monandrous or monadelphous, each floret consisting of a single stamen, or of a few united, collected in a deciduous catkin about a common rachis ; anthers two or many-lobed ; pollen large : Fer- tile flowers, generally in cones, sometimes solitary ; ovary in the cones spread open, and having the ap- pearance of a flat scale destitute of style or stigma, and arising from the axil of a membranous bractca ; ovules naked, in the cones in pairs on the face of the ovary, having an inverted position, in the solitary flowers erect ; fruit consisting either of a solitary naked seed or a cone ; seeds with a hard, crustaceous covering ; embryo in the midst of a fleshy and oily albumen, with two or many opposite cotyledons. The plants belonging to this order are resinous trees or shrubs with branched trunks, and linear, rigid, entire leaves, furnished with parallel veins, and some- times sheathed at the base. They are found in va- j rious and very different parts of the globe ; some in- habiting the cold regions of the north, and others growing in the hottest parts of the Indian Archi- pelago. They abound in the temperate climates of Europe, Asia, and America, and many species are furnished by the Australian continent. The order has been divided into three sections : I. AbictinecE, the pine tribe, including the genera Abies, fir or spruce ; Pinus, pine ; Larix, larch ; Cedrus, cedar ; Cumiinghamia, Dammara, Araucaria, &c. II. Cupressincce, the cypress tribe, comprehending the genera Cuprcssus, cypress, Junipcrus, juniper, Thuja, &c. III. Taxincee, the yew tribe, including Taxus, yew, Ephedra, Podocarpus, &c. All the species of this extensive family are raised from seeds. The cones are gathered in winter and exposed to the sun, or the gentle heat of a fire or kiln. In this manner the scales are opened, and the seeds easily taken out. The cones of the Scotch pine, the common spruce and larch, require kiln heat ; while those of the Weymouth pine, silver fir, and balm of Gilead fir, give out their seeds easily without the aid of artificial heat. So long as the cones are kept close ! the seeds remain uninjured, and they ought not be opened long before the seeds are sown, otherwise germination is apt to be prevented. The seeds are sown in the months of March and April, in soft rich soil. They ought at first to be screened from \ the sun and protected from birds. They require a covering of earth, varying from one-fifth of an inch to an inch and a half. For the spruce fir one inch is required, for the silver fir, and balm of Gilead fir, the depth of soil varies from one-half to three- 130 CONIFERS. quarters of an inch, while for the American species one-fifth only is requisite. The seeds of most of them, except the stone pine and a few others, come up very soon. They are thinned and put in rows at the distance of four or five inches, and three or four in the row. After being a your in these rows, they are removed to others two feet distant from each other. After being two years in the seed-bed, and having at- tained the height of six or seven feet, they are finally planted out, and great care is requisite in the removal not to allow the roots to be long exposed, for though the plants are hardy when grown up, they are very tender when young. Fir plantations should be regu- larly thinned from the time the trees are six or seven feet high, until they attain the height of twenty or thirty feet. At this time the trees, if they are Scotch, spruce, or silver firs, ought to be at least twenty feet distant from each other. Larch firs require more shelter, and ought to be. a little closer. Firs, in gene- ral, require plenty of room, in order that their branches may expand fully. They cannot be pruned, on ac- count of the large quantity of sap which they contain, and which flows freely from the slightest incision, weakening the tree much, and sometimes stopping its growth for several years. Various resinous products are furnished by the fir, pine, and larch tribe. They may be divided into — 1, those which are yielded by spontaneous exudation, such as Briancon manna, &c. ; 2, those which are got by making wounds into the wood through the bark, as the various kinds of turpentine ; 3, those obtained by decoction, as the essence of spruce, and 4, those procured by lire, as tar and pitch. The common oil of turpentine of the pharmaco- poeias is procured by distillation, and is the product of several species of pine. It is a transparent, limpid, volatile fluid, having a hot pungent taste, and a pow- erful odour. It is highly inflammable, and is lighter than water. Its propenies, in general, are of a sti- mulating nature, and it is much used in medicine. It acts upon the bowels, and increases the secretion of urine, imparting to it a smell of violets. In large doses it is particularly beneficial in tape-worm. It is also used in epilepsy and in inflammation of the bowels. When given in large doses, it produces temporary intoxication. Externally it is employed in palsy, nervous pains and spasms, and in burns. It is also said to be useful in checking bleeding. It has been lately employed, with great success, in the pro- cess of boring or cutting glass, as it is said that a common awl may be forced through a plate of glass, provided oil of turpentine is kept constantly applied. The residuum of the distillation of oil of turpentine receives different names according to the mode in which it is conducted. When the distillation is per- formed without addition, and continued till all the essential oil is driven off, then there remain colophony ; but if water is added to the mass while fluid, or thoroughly blended with the rosin by agitation, then we procure yellow rosin. In procuring tar, a conical cavity is dug in the earth which communicates with a reservoir at the bottom and billets of fir are then placed so as to fill the cavity and form a cone above it. The mass is then kindlec at the top, and covered over with turf. In this way the combustion goes on slowly, and all the liquefiec tar accumulates at the bottom. By boiling the tar for a long time, all the volatile matter is driven oft' and a substance called pitch is left. Tar or pitch ointment is applied externally in ring- worm and various cutaneous diseases. Tar water has )een recommended as a diuretic and sudorific. Tar umigation has been considered beneficial in consump- ion, by promoting expectoration. Cedrus Libani, cedar of Lebanon, (Pinits Cedrus of Linnaeus,) is a native of the coldest parts of the moun- :ains of Libanus, Ainanus, and Taurus. In these places the tree formerly grew in large quantities. The i'orest of Lebanon was famous in the days of Solo- mon ; and in his time cedars were said to be " as tho sycamores that are in the vale for abundance." Now- a-days, however, cedars are by no means common in Palestine. A few still exist, some of them nine feet in diameter. The cedar is a large, wide-spreading tree, not so lofty as is frequently represented, and as Milton would make us believe, when he says — Over head upgrcw, Insuperable height of loftiest shade, Cedar, aiid pine, or fir, or branching palm. The timber of the cedar is very indestructible, and was anciently much used in the decoration of temples. In the temple of Apollo, at Utica, some beams of Numidian cedar are said to have been 1200 years old. This wood was also employed in forming sta- tues ; and it is supposed that the famous statue of Diana at Ephesus was constructed of it. The wood was also used in embalming and in preventing putre- faction. The tree yields a saccharine resinous sub- stance. The cedar was introduced into Britain in 1683; and in some parts of England, as at Witton Park and Zion House, it thrives well. In the Garden of Plants at Paris, there is a fine specimen of the tree which was planted by Jussieu. The cones of cedar must be kept for a year before the seeds are taken out, on account of the softness of the seeds and the resinous matter with which they are surrounded. The cones are imported from the Le- vant, and the seeds retain their vegetating powers for many years. Cedrus dcodara, sacred Indian cedar, grows on the high mountains of Nepaul and Thibet, at an elevation of 10 or 12,000 feet above the level of the sea. It is regarded with veneration by the Hindoos, and fur- nishes durable and valuable timber. Juniperus communis, common juniper, is common in many parts of Europe. A dwarf trailing variety of it is found on the mountains of Wales, Scotland, and Ireland. It is an evergreen shrub, furnishing a hard, reddish wood, which serves for veneering. Its bark is made into ropes. Its berries are imported in con- siderable quantities from Holland and Italy. They have a strong, disagreeable smell, and a warm, pun- gent, bitterish taste. They consist of essential oil and sweet mucilaginous matter. This oil, which is of a green colour, is separated by distillation, and give.-, the peculiar flavour and properties to Hollands. Gin was formerly made in imitation of Hollands, by the addition of juniper ; but it is now made from whiskey rectified on turpentine. Both the berries and the tops of the juniper are used medicinally. They possess tonic, stimulant, and diuretic properties. These qualities are owing to the essential oil which they contain. An infusion of the tops has been used in dropsy. The juniper is the badge of the clan Murray in Scotland. Juniperus sabina, common sa\ ine, is a low evergreen CONIFERS. 131 shrub, found native in the south of Europe, and fre- quently met with in gardens. Its leaves have an acrid bitter taste and a strong smell, and the whole plant yields an essential oil, which possesses very active qualities. The general properties of the plant are stimulant and diuretic. It is prescribed sometimes in cases of worms and gout. An ointment prepared from the leaves, of a green colour, and having the odour of the plant, is used as an issue to promote the discharge from blistered surfaces. Juniper us Virginiana, red or Virginian cedar, is a tree of great size and beauty. It sometimes grows to the height of forty i'eet, and furnishes valuable timber, which is used for parts of buildings, and other im- portant purposes. It is found in North America and the West Indies. The heartwood is of a red colour, and moderately soft, and is used in the formation of common cedar pencils. Jiinipcrii.i o.i' ./red ms, sharp cedar, or brown-berried juniper, is a native of Spain, the south of France, and the Levant, and was used in ancient times in the for- mation of statues. Its wood furnishes, by distillation, an empyreumatic oil, called cedar oil, which is used as a vermifuge, and as an article of veterinary medi- cine. Juniperus lycia yields a gum-resin, similar to oli- banum. All the junipers are raised from seeds, which ought to be sown in a light soil as soon as they arc ripe. Another important genus of this extensive order is Cuprcssus, or cypress. Cupressm xcmpcrvircns, common, evergreen or fune- real cypress, is a native of Cyprus and Crete, and grows on Mount Ida. It is common in old gardens, and is often planted in clumps of evergreens. In consequence of the gloomy hue of the leaves, branches of it were formerly placed before the doors of the deceased, and were used at funerals. It furnishes a valuable and durable wood, which resists the attacks of insects, and is used in Crete, Malta, and the Levant for the purposes of building. The tree was planted by the Moors round their palaces, and by the ancient and modern Romans in their villa gardens. The doors of St. Peter's, which lasted from the time of Constantine, for a period of 1 100 years, were made of cypress wood. This is supposed to be the wood of which the ark was made, and called in the scrip- tures Gopher or Shittim wood. Cypress wood was used by the Greeks in the time of Thucydides for the coffins of their eminent warriors, and we find the chests of the Egyptian mummies sometimes made of it. Cuprexsus thyoides, white cedar, is a middle-sized evergreen, found native in North America and China. In the United States it occupies large tracts of coun- try, denominated cedar swamps. Its wood is soft, of a red colour, and diffuses an aromatic odour. TfU'tis baccata, common yew, is a native of Britain, the northern parts of Europe, and North America. It is frequently cultivated in pleasure grounds, and used to be clipped and fashioned in a most fantastic and remarkable manner. From being considered a lasting emblem of immortality, it was frequently planted in churchyards, and the sight of it is conse- quently apt to excite gloomy and melancholy ideas. Pennant mentions a yew in a churchyard in the High- lands of Scotland, at the entrance of Glen Lyon, the remains of which measured fifty-six feet and a half in circumference. In Wales and Ireland twigs of the yew-tree are often carried at funerals. The yew was formerly looked upon as possessing poisonous and deleterious properties, and was said to prove fatal to an\' one who slept under its shade. Hence it acquired the appellation of " deadly yew." These notions, however, are now found to be totally erroneous. The berries of the yew, which are of a red colour, are quite innocuous, and do not possess the poisonous qualities formerly attributed to them. The leaves, however, are found to possess slight nar- cotic properties. The wood of the tree is red, hard, and beautifully veined. It is used by cabinet-makers, and was in early times imported in large quantity for the purpose of making bows. It was in those days planted extensively to furnish bows to our warlike ancestors, Who drew, And almost joined the horns of the tough yew. In later times, since archery is less practised, the cultivation of the yew is less attended to. The tree is propagated by seeds. It is well known as the badge of the clan Fraser. Thuja occidcntalix is the common arbor vitac of our gardens. It is a native of Canada and Siberia, and sometimes acquires the height of thirty or forty feet. The first specimen of the tree brought to Europe, was planted in the royal garden at Fontarableau. in the reign of Francis the First. The wood is used in the formation of boats and inclosures, as well as in the construction of houses. In England it is fre- quently used by turners. The leaves are said to have bec:i pre.-i'riljed in rheumatism. Another species, Thuja orienlalis, is found in China. Thuja ar licit I at a, or jointed thuga, yields a yellow brittle resinous substance, having an acrid aromatic taste, to which the name of sandarach is applied. It is employed as a varnish. This resin is stated by some authors to be a product of the common juniper. The coniferous or cone-bearing plants found in Australasia are chiefly included under the genera, Araucaria, Dammar a, Dacrydium, Cunninghaima, and AKiiigin. Araitcaria. or Altingia excelsa, Norfolk Island pine, is an immense tree, which sometimes attains the height of two hundred feet, with a circumference of thirty feet. The wood which it yields is not valuable, on account of its want of durability and solidity. Its bark yields a resinous substance. It does not thrive well in the open air in this country. Species of the genus araucaria, similar to this, would appear, by the researches of fossil botanists, to have existed formerly in Britain. Araucaria Dom- beyi or imbricafa, is a South American species, the wood of which is valuable, and its seeds are eaten as articles of food when fresh. Dammara oncntalis, Dammar pine (PI mis Dant- mara of Lambert), is a native of Amboyna, and fur- nishes a peculiar resinous matter. Some say that liquid storax is procured from it. Dammara Australis, Cowdie pine, or Kawic-tree of New Zealand, attains the height of two hundred feet, and yields a light compact wood, free from knots. Dacrydium ta.vifoliinti, or Kakaterro, another New Zealand pine, is said to equal the Cowdie pine in height. The branches of this pine yield spruce. We have thus endeavoured to describe some of the plants contained in this extensive order. They are of great interest and importance to man, both on ac- count of the valuable timber which they furnish, and 12 132 the useful secretions which are procured from them. Woods and forests, both in cultivated and savage countries, consist in most instances of trees belonging to this family. They are remarkable for their size, the rapidity with which they grow, and the majestic appearance which they present. They are almost invariably natives of the northern, although occa- sionally found in the southern hemisphere, and may be said to supply, by their dense persistent leaves, the place occupied by the evergreens of warmer climates. CONIROSTRA, one of the divisions into which Cuvier arranges his great order of Passerine birds, and which expresses generally that the bills of such birds are more or less of a conical form, that is, thick at the base, and tapering to the point. For a more particular account of the propriety of using the name, and of the place which the birds hold in the system, see the article BIRD. CONIUM (Linnaeus). Is the well-known and dreaded hemlock. The spotted hemlock of this coun- try is accounted highly poisonous, though it is useful in some cases when applied outwardly. Two of the South American species, namely, the C. arracacha and the C. moschatum, are both cultivated there for the sake of their large parsnep-like roots, which are useful articles of diet among the natives. The arra- cacha is now under a trial of naturalisation in this country, with the expectation that, if hardy enough for our climate, it will prove an important addition to our stock of culinary vegetables. CONNARACE^E. A natural order of dicotyle- donous or exogenous plants, containing five or six genera, and between twenty and thirty known species. This family is by some authors looked upon as a dis- tinct order, while by others it is considered merely as a section of Terebinthacece. It is nearly allied to Legu- minoscc, from which it is distinguished by the radicle being at the extremity most remote from the hilum. From Burseracece, Cassuviece, and other terebintha- ceous orders, it differs in the total want of resinous juice. Considered as a separate order, its essential cha- racters are : Flowers hermaphrodite, rarely unisexual ; calyx five-partite, regular, persistent; petals five, in- serted on the calyx, with an imbricated, rarely valvate aestivation ; stamens ten ; filaments usually monadel- phous; carpels five, one-styled, distinct, sometimes solitary by imperfection ; seeds erect, from the bottom of the cell, in pairs or solitary, with or without albu- men, often axillate ; radicle superior, at the extremity opposite the hilum ; cotyledons thick and fleshy in the seeds without albumen, foliaceous in those with albumen. The plants belonging to this order are trees ,or shrubs, with terminal and axillary flowers, in racemes or panicles, and compound alternate leaves, without dots or stipules. They are found in the tropical regions of Asia, Africa, and America. Little is known in regard to their properties. The chief genera of the order are : Contiarus, Om- phalobium, and Cnestis. CONOCARPUS (Jacquin). A genus of shrubs and trees, natives of the West Indies and South America. Linnaean class and order Pentandr'ui Monogynia, and natural order CombretacecE. Generic character : flowers in a head ; calyx pitcher-shaped, five-cleft, and deciduous ; stamens five (ten), inserted in the calyx ; anthers heart-shaped, two-celled, burst- ing lengthwise ; style and stigmas simple, scaly, CONIROSTRA— CON OP I D jE. corky, one-seeded. This is called the button-tree in Jamaica, and has been many years in European collections. It thrives in a mixture of loam and moor earth, and is propagated by cuttings. CONOCEPHALUS (Thunberg). An exotic- genus of orthopterous insects, belonging to the section Sallatoria, and family of Gryllula; (Leach), or grass- hopper, with long slender antenna?. CONOLITES (Lamarck). A fossil genus ot molluscs. The shell is nearly straight, or only slightly curved, the sides very thin, the cavity filled, through its whole length, by a succession of simple chambers, increasing from the first to the last, which is at a great distance from the opening ; the siphon is central or marginal. The genus is subdivided into four species, but the distinctions are extremely minute, and considerable doubts exist as to the propriety of separating it from some others of the family Ortho- cerata. Authors have variously named the species, which confirms the difficulty of distinguishing them. De Montfort calls one Acheloite, another Amimomius, and a third Tluilamnhts. CONOPID^E (Leach). A family of dipterous in- sects, belonging to the section Athericera, having for its type the genus Conops of Linnaeus, and distin- guished by the mouth being elongated into a slender, pointed, and elbowed proboscis. The nerving of the wings is very simple, and resembles that of the do- mestic fly. The family comprises the genera Cephcnes, Conops, Zodion,and Myopa, having the body long and narrow ; and Buccntcs, Proscna, and Stomoxys (form- ing the family Stomoxyda: of Meigen and Stephens), having the body short, and very much resembling the common fly. The structure of these different genera are very diversified, as are also the habits of such as we are acquainted with. The larvae of conops are stated to reside in the abdominal cavity of the humble bee (Bombm}, and St. Fargeau states, that he had noticed the conopides introducing themselves into the nests of wasps, so that he supposes that the larvae of the former, in all probability, subsist upon those of the latter. Latreille also says, that Conops rujipcs has been observed in a recently developed state, with the w ings still soft, to come out of the body of a bombus. An apod larva found in the body of the stone humble bee (Bombus lapidaria], and considered by Latreille and others to have been that of the same species of conops, has been made the subject of a valuable memoir by Messrs. Audouin and Lachat, contained in the first volume of the Memoirs of the Natural History Society of Paris. The conops, when arrived at the perfect state, frequent flowers, as do also the zodions and myopic. M. Robincau Desvoidy has informed M. St. Fargeau, that a larva which he had found in the body of a caterpillar produced a fly of the latter genus. — In like manner the larvae of Bucentes, observed by De Geer, had been reared in the chrysalis of a moth, although the perfect insect, as well as the prosenae, live upon flowers. The genus Stomoxys comprises that tormenting insect which is so often mistaken for the domestic fly, and which does not cease its irritating attacks until the first frosts of winter. The name of the genus indicates the cause of this irritation, being derived from the Greek, and signify- ing sharp mouth ; the proboscis being very acute and horny, so as to enable it to puncture not only the skin of man, but also the tougher coats of the ox and horse. After it has filled itself with its sanguinary repast, the CONOSPERMUM-CONUS. wound docs not at once close, but continues to bleed for a time. The common species (Stomoxyt calcitrans) is most abundant in autumn, hence the origin of the common error that at this period of the year the do- mestic fly is most tormenting. Some individuals of this species (probably impregnated females) hide them- selves during the winter, becoming torpid, sometimes its many as a score may be found packed closely to- gether in the stumps of old trees, especially in situa- tions where a moisture has exuded which has probably served for their food, or upon which they will feed when they regain their activity. M. Desvoidy has united the Stomoxydce with'the Muscidce, and has formed the Stomoxys irritam into the genus Heema- tobut. CONOSPERMUM (R. Brown). New Holland ornamental ever-green shrubs, belonging to Tetrandria monogynia, and to the natural order Proteaccae. Generic character : calyx tubular, gaping ; upper segment hollow at the base ; anthers three, side one halved, the upper two lobed ; stigma free ; nut inversely cone-shaped, crowned with rigid hairs. These plants have narrow heath or yew-like leaves, and therefore add variety to the green-house collec- tion. CONOVULUS (Lamarck ; a Volute of Linnteus). One of its species has also been classed, by Lamarck, with the genus Tornatella ; both of them are now, however, placed with the Pcdipes, in the second family AuriculaceJt rare and beautiful known, but amongst the most common numbers exist, which, if equally rare, would rival them in elegance of form, colouring, and pencilling. In the records of conchological extravagance, it is stated that some examples of rare cones have been so strongly competed for by amateur collectors, that one hundred pounds have been given for them ; it is, indeed, within our own knowledge, that twenty pounds have been paid for a fine specimen of the cedonulli and aurisiacus cones ; and even at the present period they could not probably be bought under half that amount. Th« somewhat trite adage of a " fool and his money being soon parted," does not, how- ever, in this instance, more particularly apply, than in a thousand others ; from the earliest ages of history mankind have been often known to sacrifice, not only immense sums, but every moral duty towards their fellow creatures, to acquire possession of an object not attainable to others on the score of riches or vanity. To a certain extent, wealth must ever command an indulgence of this or any other bad passion ; but, happily, the satisfaction of doing good so much pre- ponderates, that instances of selfish extravagance are hourly becoming less conspicuous. The blind gifts of fortune are dispensed with a liberal, discriminating judgment, by those who enjoy a superfluity of them, and are blessed with minds so constituted, as to appreciate the sacred duties which rank or wealth impose upon them, by alleviating the sufferings of beings less fortunately placed in the scale of worldly enjoyment than themselves. CONVALLARIA (Linnaeus). The C. majali* is a British plant, and one of the most valued of the British flora, under the name of Lily of the Valley. Linnsean class and order, Hcxandria Monogynia; and natural order Smilacete. Generic character : corolla tubular, limb six-cleft ; stamens joined to the tube ; filaments awl-shaped ; anthers erect, and somewhat egg or heart-shaped ; style columnar ; stigma headed. Berry of three cells, each containing several seeds. C O N V O L V U L A C E JE. 135 The simple beauty of the smooth fresh green leaves, surrounding and serving as a background to the ele- gant racemes of pure white nodding flowers, is a con- trast which enhances the value of both. Those who are the least sensible of the beauty of flowers, appear charmed with the simple elegance of the lily of the valley. So much has it been cultivated in every gar- den, that two varieties have been already obtained, namely, the red flowering and the double ; all of which are easily increased by division, and will thrive in any shady place. CONVOLVULACE.E. The bindweed family. A natural order of dicotyledonous plants, containing upwards of twenty genera, and between two and three hundred known species. Its plaited corolla, and climbing habit, are the characters by which this order is best distinguished from all others. It bears an affinity to Cordificfic- in its shrivelled coulcdons, and it is also allied to /'<,•/, nd IIydn>l< Its essential chancters are : calyx with five divisions, persistent ; corolla mqnopetalou?, hypogy- nous, regular, the limb five-cleft, generally plaited and deciduous ; stamens live, inserted at the bottom of the corolla, and alternate with its segment? ; ovary single, two to four-celled, rarely one-celled, some- times in two or four divisions, with few definite erect ovules ; style one, often divided at the apex, some- times as far as the base ; stigmas obtuse or acute ; capsule one to four-celled, the valves corresponding to the angles of a free dissepiment, bearing the seeds at its base, sometimes without valves, or opening transversely; seeds with a small quantity of mucilagin- ous albumen ; embryo curved ; cotyledons wrinkled ; radicle inferior. The plants belonging to this order are herbs or shrubs, which are usual! v climbing, milky, smooth, or with a simple pubescence. Their leaves are alternate undivided or lobed, without stipules, and their in- florescence terminal or axillary. They have fre- quently showy flowers, which expand beneath the influence of bright sunshine. They are found twining round other phmts, or creeping among weeds on the sea-shore in the tropical regions of the globe, and are by no means abundant in cold climates. Their roots abound in an acrid milky resinous juice, possessing purgative qualities. Some of them are employed as articles of food. The chief genera of the order are, Convolvulus, (W;/.s/Viw, Ipomcea, Cuscuta, Evolvulus, Argyreia, Falkia, and Rftzia. Convolvulut, bindweed, is a very extensive genus, and includes some species which are prized on account of their beauty, or the valuable products which they furnish. Convolvulus, or Ipomcea jalapa, is a climbing peren- nial plant, found near Xalappa, a town of Mexico. It was first brought to Europe in 1610. The root of the plant furnishes (he medicinal jalap. It is a tuberous egir-shaped root, which, when fresh, is white and lactescent, but, as imported, is generally covered with a blackish wrinkled bark. It is sometimes brought to this country in the form of thin transverse slices, having a greyish colour internally. The tubers, when sound, are compact, hard, and heavy, and break with a resinous fracture. They have a nauseous taste and smell, and seldom exceed a few ounces in weight, with a diameter of two or three inches. When powdered, jalap has a yellowish grey colour. The roots of common bryony, the marvel of Peru (MirabJ&s jalapa), and of other species of convol- vulus, are often mixed with those of the true jalap. Jalap has been ascertained by analysis to consist of resin, extractive matter, starch, vegetable albumen, woody fibre, and various salts. A substance has lately )een obtained from jalap possessing powerful purga- ivo properties, and which, from being considered its active principle, has been denominated Jalapine. The observations made in regard to it however, are not as yet satisfactory. The properties of jalap reside chiefly in the resin. When administered in small doses, of ten or fifteen grains, this medicine is an effectual, safe, and mild purgative ; but when given in large doses it produces griping, watery evacuations, and may even excite inflammatory action. Camphor is one of the best substances for preventing its griping effects. It is frequently prescribed in combination with calomel and cream of tartar. When mixed with two parts of the latter salt, it constitutes the compound jalap powder of the Edinburgh Pharmacopoeia. The watery extract of jalap possesses the proper- ties of the root in a weak degree. The resin, by itself, produces distressing symptoms, without much eii'eet in evacuating the bowels. Diluted alcohol, or proof spirit, dissolves almost all the active ingredients of jalap. The root of Convolvulus pan.dural.us is used in the United States as a substitute for jalap. Convolvulus team-mania (scammony), is another climbing species of bindweed, found in the Levant, Syria, and Turkey, and growing abundantly on the mountains between Aleppo and Latakia. The roots of this plant are three or four feet long, and nine or twelve inches in circumference, and when cut yield a milky juice, which concretes, and forms the gum- resin known in medicine by the name of scammony. The following is the mode in which the gum-resin is collected : — The earth being removed from the upper part of the root about the month of June, an incision is made obliquely across it, and the milky juice which exudes is allowed to flow into a shell or cup placed at the lower end of the cut. Afcer the vessel has been left for twelve hours, it is removed, and the concrete juice is taken out. Each root yields only a few drachms. The produce of several routs is then collected, and put into packages or drums, as they are called, which weigh from 75 to 125 pounds. The best scammony is brought from Aleppo. An inferior sort is exported from Smyrna in the form of cakes, like wax, packed in chests. This would appear to be the produce of another plant, Pcriploca scammonium. Scammony is frequently adulterated with sand, ashes, and the juice of other plants, such as ci/nanclnim, monspeliacum, &c. The Smyrna scammony is said to be sometimes an entirely artificial compound, con- taining no real scammony whatever. Pure Aleppo scammony occurs in the form of light, spongy, friable masses, having a heavy di-- a»reeable smell, a bitter acrid taste, and a blackish cr dark grey colour. When broken, it exhibits a smooth somewhat shining fracture, and when powdered is of a light grey, or whitish colour. Scammony consists of resin, gum, and extractive matter. It possesses powerful purgative qualities, which reside in the resin, of which it is chiefly composed. It is ad- ministered in doses of five or ten grains, and is frequently prescribed in combination with calomel, 136 CONVOLVULUS— COPPER jalap, cream of tartar, and sulphate of potass. It is sometimes triturated with sugar or almonds, and is then said to be mild in its operation. It is often used in cases of dropsy and worms. Both scammony and jalap, when rubbed externally oil the skin, produce purgative effects. Convolvulus arvensis, small bindweed, is common in corn-fields and by the sides of hedges in Britain. Its flowers are small and rose-coloured, and it has a white-jointed root, which runs deep into the ground, and is difficult of extirpation. It twines round wheat and other kinds of grain, and is a troublesome weed in cultivated grounds. Its presence is said to indi- cate in general a dry soil. Its juice is slightly purgacive, and its blossoms give to water a deep yellow colour, which is increased by the addition of alum and alkaline substances. Convolvulus, or Calystegia septum, great bindweed, is another indigenous species, which is much larger than the preceding, and produces showy white flowers. The inspissated juice, in doses of twenty or thirty grains, is said to be purgative. Convolvulus, or Calystegia Soldanella, sea-side bind- weed, is the only other British species. It is common on sandy places by the sea-shore. Its root is long and creeping, and its flowers few, large, and rose- coloured. Convolvulus batatas, skirrets of Peru, Spanish potatoes, or the common sweet potato of Europe, is a native of the East and West Indies and of China. It was first brought to Spain from the West Indies, and its root used to be imported into this country as an article of food. Its root is the potato of Shak- speare, and the writers of his day, at which time our present potato (Solatium tuberosum) was scarcely known in Europe. In tropical countries it is still cultivated like the potato. Not only its tubers, but also its young leaves and shoots, are boiled and eaten. The root of Convolvulus edulis is also fre- quently used as food. The roots of Convolvulus Jloridus and scnparius produce sneezing. The wood of the latter species, which grows in the Canary Islands, is remarkable for its fine rose-like odour. Convolvulus repens is em- ployed as a pot-herb in the East Indies and China. Convolvulus turpethum (turbith or turpetli), is a native of the East Indies, and furnishes a root which has been used medicinally as a cathartic. A resinous matter is obtained from it. Convolvulus Malabaricus, a native of the Malabar coast and Cochin-China, is considered in India a valuable horse-medicine. The genus Ipomcea consists of twining stove plants, which are easily cultivated, and flower very readily. Up- wards of one hundred species are described by botanists. They are remarkable for the beauty of their flowers, which, though they are individually short-lived, yet they are succeeded so rapidly by others, that there are few more showy ornaments of the forests in warm countries, or of stoves in our own. Ipomcea tuberosa is a plant of great beauty and frag- rance. In Jamaica it is evergreen. It is thickly covered with leaves and large flowers, and is a beautiful ornament of arbours. It yields a milky juice, which, when concrete, resembles scanimony. Ipomcea inamoclit is a beautiful annual. Its root is used as a sternutatory. Cwtcuta — dodder, a genus of leafless plants, which, after germinating in the ground and deriving nourish- ment from it, become parasitical, and attach them- selves to some plants in the neighbourhood. Tiiei'r stalks twine round these plants, contrary to the sun's apparent motion, or from right to left, sending out from their inner sides little papillae or tubercles, which attach themselves to the bark of the supporting plant, and finally become firmly and intimately united with it. They then derive their support and nourish- ment from the plant to which they become attached. Cuscuta Europeea, great dodder, is found in Britain on nettles, flax, &c., and produces flowers of a pale yellowish rose-colour. Cuscuta epithymam, lesser dodder, another British species, is found on furze, heath, and thyme. It is distinguished from the pro- ceding species by having a scale at the base of each stamen. CONVOLVULUS (Linnaeus), is the very sig- nificant generic name of all that family of plants called bindweed. They belong to the fifth class and first order of Linnaeus, and, as we have already stated in the previous article, give a title to an order in the natural system. This genus is spread over every part of the known world, and appears in every degree of bulk and beauty, and of every grade as to duration ; some are annuals which embellish our flower borders for a few months.and then disappear; somearc biennials, but the great majority are perennials. They are nearly all either creepers, twiners, or climbers ; many are trou- blesome weeds, though the flowers of all are »no,wy. They are all easy of cultivation, and thrive in almost any kind of soil. This genus, though still very nume- rous, was formerly much more so, many of the species having been separated, and added to the two con- •enerous genera of Ipomcea and Calyttegia, CONYZA (Linnaeus). A genus of shrubs and herbaceous plants found in many and distant parts of ;he world, and known by the common name of flea- sane. Linnsean class and order Syngenesia supcrflua, and natural order Composite. Generic character : anthodium scaly ; receptacle naked ; florets of the ray trifid, or somewhat two-lipped. The fleabane is a British biennial of no great beauty ; the foreign are mostly of like character. Some of the shrubby species are kept in greenhouses, where they are easily increased by cuttings treated in the usual way. COOKIA (Sonnerat). A genus of fruit tree indi- genous to China and the neighbouring countries, and called by the natives wampee. Linnaean class and order Decandria monogynia, and natural order Auran- tiacetE. Generic characters : calyx in five parts ; petals five, white, and villous ; stamens filaments linear; anthers roundish, apple imperfectly two-celled, one seed in each. The tree has been long in our collections, and grows well in a large pot, in loamy soil. From what we have experienced of other Chinese plants, such as the tea-plant, camellia, and others, it may be expected that the wampee may bear our winters if planted against a south wall, and be allowed sufficient protection against frost. COOT. See FULICA. COPPER. The mineralised ores of this metal are very numerous, and it is found in a native state in many parts of the world. Native copper occurs in a variety of forms, massive, dendritic, granular, and crystallised in cubes, octohedra, &c. This mine- ral is accompanied by several other substances, as the ores of zinc, and occasionally of lead ; sometimes of tin, silver, and arsenic, with quartz and fluate of lime, and calcareous spar in abundance. It is met with in Cornwall, the Hartz, Saxony, Sweden, and COPRIS— CORIARIE.E. 18? in America, but the native coppers of Japan and 15razil are usually alloyed by gold. It is commonly accompanied by quartz, heavy spar, and calcareous spar, except in Cornwall. Mineralised by a certain proportion of oxygen, it forms a beautiful mineral, called the red oxide of copper, which assumes a great variety of forms, all of which may be traced into the regular octahedra ; but with an increased proportion of oxygen, it assumes a black hue, and is mostly pulverulent. The foliated and compact red copper ore occurs in different veins in the mine of Huel Gorland, in Corn- wall. All the veins traverse granite, and three of them, viz. the North Lode, the Great Gossan Lode, and the Muttrel Lode, afford the red copper ore. In the North Lode it is associated with fluor spar. In the Great Gossan Lode it occurs in considerable quantity, and is occasionally intermixed with native copper ; higher up in the same vein there is abun- dance of fluor spar, sometimes intermixed with arsenical pyrites, and copper pyrites. In the Muttrel Lode the copper ore is occasionally accompanied with '•opper glance, or vitreous copper ore, black oxide of copper, olivenite, arsenical pyrites, quartz, and fluor spar. It is also found in several other mines. Small portions of this ore occurs, along with native copper, in the trap-rocks of Nalsoe, one of the Faroe Islands : also in the mine of Aardal in Norway, and Garpa in East Gothland, in Sweden. It occurs but sparingly, and along with native copper, in the Kemmclsberg, in the Hartz ; near Freyberg, along with native copper, ochry-brown iron ore, lamellar, heavy spar, and quartz. In Asia this ore of copper occurs in the Uralian chain of mountains, and also in the mines of Kolywan. In America it is principally found in Chili and Peru. Both the blue and green carbonate of copper are found in a native state, the latter under the name ot MALACHITE, which see. COPRIS (Geoffroy). A very extensive genus ol coleopterous insects belong to the section Pentamera and sub-section Lamctticornes, and family Scarabidae having the body large and thick ; the antenna? termi- nated by a three-jointed fan-like club ; the head anc thorax often armed with powerful horns, especially ia the males j the scutellum appears entirely wantin and the four posterior tibia; arc strongly dilated anc obliquely truncate at the extremity. The Coun De Jean enumerates eighty-four species of this genus which are for the most part inhabitants of the warme quarters of the globe, especially frequenting Africs and the East Indies, where they are important agents in the economy of nature, the eggs being buried in the excrement of various animals, within which the larvae feed and the beetles are perfected. The species which we have figured in our plate of beetles, from the collection of the Rev. F. W. Hope, is the Copris isidis of Savigny, one of the largest insects in the genus, of a black colour (as indeed are all the species' with reddish hairs in front of the thorax ; it is fron Egypt. There is only one British species, the Scara bains tunaris of Linnaeus (the Scarabasm emarginatu of Fabricius being merely the female). It is of ; black colour, with the single upright horn in th middle of the head in the male. It is nearly an inch long, and may be occasionally found emerging frorr holes made in the ground beneath cow-dung, am taking flight towards sunset. CORALLIFERA, a numerous order of marine animals belonging to the class POLYPI, which see. CORDIACEyE. A natural order of dicoty.e- lonous plants, containing six or eight genera, and ipwards of fifty species. It is closely allied to BoraginecE, and by many authors is looked upon as a section of that order. It is distinguished, however, )y its general habit, its plaited cotyledons and dicho- omous style. It bears an affinity also to Convolvu- lacece, from which it differs in its inverted embryo and drupaceous fruit. The essential characters of the order are : calyx nferior, five-toothed : corolla monopetalous, with the imb in five divisions ; stamens alternate with the segments of the corolla, out of which they arise ; ovary superior, four celled, with a pendulous ovule in :ach cell ; fruit a four-celled drupe ; embryo inverted ; :otyledons plaited or shrivelled longitudinally ; seeds without albumen. The plants belonging to the order are trees with panicled, bracteate flowers, and alternate rough leaves without stipules. They are found in tropical regions in both hemispheres. They generally yield emollient and mucilaginous fruit, but little is known in regard to their properties. The chief genera of the order are : Cordia, Varronia, Gcraschanthus, Ccrdana, Cordiopsis, and Mffnmsi Cordia mi/xa is a large tree, growing in the East Indies, and yielding a yellow-coloured fruit the size of a cherry, which is eaten by the natives. The bark of the tree is tonic, and is used in Java in cases of fever. Its wood is tough and solid, and is employed to pro- cure fire by friction. The leaves are bruised with those of Dxiura mctcl, and applied to the forehead in headach. A kind of glue is prepared from the fruit. Cordia aebestcnn is a very ornamental tree, on account of its large tubular scarlet flowers. Its wood is odoriferous when burnt ; a small bit of it put on a pan of heated coals will perfume a whole house. From the juice of the leaves, with that of a species of fig, the inhabitants of Otaheite procure a fine red colour, with which they dye their clothes. The fruit of this and the last-mentioned species are commonly known by the name of sebesten plums. These are occasionally brought to Europe in a dried state, and their pulp is said to act as a laxative. Cordia collococca is called in India clammy cherry or Turkey berry tree. Its leaves are used in that country to feed poultry. CORIARIEJS. A natural order of dicotyle- donous plants, containing only one known genus and seven species. It is allied to Ochnaceee, but differs in. having no style, and in its stigmata being long, linear and distinct. It also resembles Rutacea; the rue family, and has some affinity with Connaraccce. The- essential characters of the order are : flowers either hermaphrodite, monoecious or dioecious ; calyx five partite ; petals five, fleshy, with an elevated keel in the inside ; stamens ten, of which five arise between the lobes of the calyx and angles of the ovary, and other five between the petals and the furrows of the ovary ; filaments thread like ; anthers oblong, two- celled ; ovary on a fleshy disc, five-angled and five- celled ; no style ; five long awl-shaped stigmas ; five carpels which are one-seeded, and close together when ripe ; seed pendulous, without albumen ; embryo straight ; radicle superior ; cotyledons fleshy. The plants belonging to this order are : shrubs with opposite square branches, opposite entire leaves, scaly buds, and terminal racemes, which arc leafy at the base. They are found in various parts of the 138 CORMORANT. world ; in the south of Europe, in Peru, New Zealand, and Mexico. Coriaria is the only genus of the order. Coriaria myrtifolia grows in hedges, and thickest in the southern parts of Europe and in the north of Africa. Its leaves and young branches are astringent, and are used in dyeing black and in tanning. The plant yields a poisonous fruit, which has proved fatal on some occasions. Several soldiers of the French army, in Catalonia, were stupefied by eating it, and some died from its effects. its leaves are said to be sometimes mixed with those of senna. According to M. Guibourt, this adulteration is detected by the infusion with hot water, having a pale yellow colour and astringent taste, by a white precipitate being thrown down by gelatin, a blue by sulphate of iron, a black by nitrate of silver and nitro-muriate of gold, and a gelatinous compound by caustic potass, CORMORANT (Phalacrocorax], a genus of sea- birds belonging to the family of Totipalma:, or those which have the hind toe included in the web of the foot, as well as the three front ones. The structure and action of a foot of this kind will be found noticed in the article BIRD ; so that we need not repeat it here. In their general characters, this genus is nearly allied to the pelicans, and were included in the same genus by Linnaeus and his followers ; but Cuvier has very properly separated them, as they are so dif- ferent both in structure and in their general economy, that the same description will not apply to them, and when that is the case there ought always to be a separation of genera. Cormorants are sometimes called sea ravens, or sea crows, and they have nearly the same voracity as the land ravens, though their prey and manner of catch- ing it are both very different. Cormorants generally fish near the shores, and are more frequently on the wing over the water than at rest upon the rocks. When they pursue their prey in the sea, they do not hesitate in coming near inhabited places ; but when they fish in the fresh waters they choose more lonely haunts. They catch their prey, which consists wholly or chiefly of fish, by the middle with the bill ; and as they cannot easily swallow it from this position, or in- deed if it is presented to the gullet in any other way than head foremost, they throw it into the air and seize it with great dexterity as it falls. All birds which fish along the surface of the water, and indeed all animals which swallow their prey without masti- cating or dividing it with the teeth, are dexterous at this mode of turning a fish. This is one of the most remarkable instances of adaptation with which we meet in nature, and ought to teach us to look for the intelligence "of the creature somewhere else than in the creature itself, is the fact that the action performed in this perfect manner by the organised animal is not the result of the organisation, neither is the organisation the result of the action. A cormorant does not catch fish by dashing into the water, and following them to a greater or less depth, as may be neces- sary, because its feet, its wings, its bill, and all the other parts of its organisation are fitted for such pur- poses, any more than it throws the fish up into the air, because it has a knowledge that the fish will come down in a more manageable posture for swallowing than that in which it is seized by the bill. As little can we say that the bill has or can have any controul over what its organisation shall be, for the organisa- tion precedes the action in the order of nature. The instinct follows the race, and is true to it ; which we find is not the case cilher in knowledge or in action with us. Therefore, when we examine the UK in- curious functions which are performed by the low- r animals (as we term them), we meet with far morn striking evidences of Almighty wisdom ami power than we do in the case of human conduct. There arc- no productions which assist us more in the forming of these general views than those birds which seek their food in the waters ; and as the cormorants find their food by skill and energy, not by craft, there are few sea birds better worthy our attention. The characters of the genus are as follows : — The bill long, or of mean length, compressed, rounded in the culrnen, straight for the greater part of its length, but much hooked at the tip of the upper mandible, and having the extremity of the lower one truncated, so as to act against the hook. The base of the bill has a small cere, and the naked skin is continued on the throat, and partially also on the face. The nos- trils are at the brow of the bill, in the form of longi- tudinal slits, and barely visible. The legs are stout, the tarsi short, and rather inclined toward ends other. The hind toes are turned inward, and included in the web of the feet ; the outer toe is the longest and strongest in the foot ; the claws are not large for the size of the foot,and that on the middle tre i< looihed on the edge. The wings ate of rather more thctn mean length, and they arc rather pointed, the second quill being the longest. They are not, however, formed for whirling and turning rapidly in the air ; and the rounded extremity of the tail further shows, that whirling in the air is not one of the principal actions of the bird. There are several species : — P. carbo, the common cormorant, or great cormo- rant. This species is common on the British shores, and in some places it moves inland to the lakes which are near the sea, or to the larger rivers, which have long tideways. In these last situations, it is often CORMORANT. found standing or nestling on trees; but as a sea-bird, its place of repose and nestling is the rocks. This is a large bird: three feet in length, nearly five feet in the extent of the wings, and weighing as much as seven pounds ; but this must be considered as the dimensions of a lartre specimen, and the sizes are apt to vary. Length of the bill about five inches, and of a dusky colour for the greater part of its length, but with the cere yellow ; tarsi, toes, and webs sooty black ; irides bright green. The plumage varies a little with the season. General colour, greenish black, with black margins to the feathers on the back, and a line of ash colour on the scapulars. In the breeding season, the neck and thighs are mottled with small white feathers, and there is a crest of long green feathers on the back of the head. In winter these feathers fall oft', and the general tint of the upper part becomes rusty. There is also a white gorget on the neck, which becomes much duller in the colour during winter. Though these birds are generally found in remote and inaccessible places for their nests, such as high trees and detached rocks, they are social with each other, and many nests are often found in the near vicinity of each other. The eggs are three or four in number, of about two ounces in weight, greenish white, and with the surface of the shell rather rough. Though cormorants are industrious and successful fishers, and as such thin the waters of their finny in- habitants to a considerable extent, yet they pursue their fishing with peace and good order, and never interfere with or annoy any other birds. It can be tamed very readily ; and a detailed account of one in a domesticated state may be found in Montagu's Ornithological Dictionary. The common cormorant extends to the very coldest parts of the northern hemisphere, being found in Greenland. Wherever, indeed, there is an open sea, and high rocks to afford the resting place which the birds most affect, there is never any want of cormo- rants, though in such places they are forced to shift their quarters with the season. They are driven not merely by being frozen out, but by the unusual departure from the coast of those fish on which they feed ; so that, if the movements of cormorants and other fishing birds were properly attended to.it would throw very considerable light, not only on the natural history of the inhabitants of the waters, but on the seasons at which fishing for the different kinds of the finny race can be carried on with the greatest success, and where every species should be sought for, when it disappears from any particular spot. All oviparous fishes, and they comprise the kinds which are most valuable to man as food, spawn on the banks or shores, or in the estuaries of rivers ; and the young remain for a considerable time near the shore before they betake themselves to the deep water. Much of the spawn is detached and brought to the surface, or washed to the water line on the shore, where it forms a very considerable part of the food of terns and other skimming birds, and also of those birds which pick up their food, by running along the sands. Therefore, we find these birds on the shore, and in the full ac- tivity of breeding and nest building where the spawn is deposited. Cormorants and other fishing birds come later, after the fry have attained a considerable size, and their breeding time comes on when the numbers and size of the young fish on the coast are a maxi- mum as taken together. When the spawn is gone, and the young fishes have attained considerable size, the skimrning birds which, by this time, have reared their broods, find it necessary to disperse themselves over the ocean. The fishing birds, properly so called, have then the shores in a great measure to themselves, arid, as the weather suits, they may be seen driving about with great activity. But their time for dispersing comes in the end, and they scatter more widely along the shores than the skimmers, as they are larger birds, and individually consume more food ; and it is on such occasions as this that the cormorants, which are perhaps the most voracious of the whole, betake themselves to the fresh waters, though, where these waters are large, and abound with fish, cormorants sometimes choose their breeding places on the trees near such waters, in the manner that has been described already. When they nestle on the rocks, or even when on trees, they do not, as is the case with many other birds, return to the same rocks, but shift about from one to another. When they are not employed in fishing, and espe- cially when they have fished to the full expansion of their wide and swelling stomachs, they sit down in a state of very dismal repose, and at other times they may be seen by dozens together, drying themselves on the rocks, with their wings spread out as flat and as motionless as if they were dead carcases which had been placed there by human art. As food, the cormorant, though a large bird, is of little or no value ; the smell of it is very rank and offensive, and the flesh, dressed in any of the common ways, would suffice to turn the stomach of a Green- lander or an Esquimaux. But, in some of the northern islands, the young are eaten, and even relished as a sort of dainty, after having been buried for twenty- four hours in the earth, which is said to remove the bad flavour of the flesh, and also to make it tender. Soup made of them in this manner is said to taste soniel/ting like hare-soup ; but we should be a little sceptical of the fact, though good soup may be made with ant/ thing in it as one ingredient, which is not of so positively offensive a nature as to spoil the rest. When regal amusements consisted more of field sports than they do in these days, there was an office of the royal household of England, known by the style and title of " Master of the King's Cormorant.*;.'' Whether such an office may not still exist, and be exercised under another name, is not a point which writers on natural history are called upon to settle ; but it is certain that, in those comparatively rude and primitive times, cormorants were trained to catch fish, and prevented from swallowing what they did catch by a tight collar of leather put round the neck. They were not difficult to train, were expert in then labour, and docile and easily managed. P. graculiis (ihc Shag, smaller cormorant, or smaller sea-crow). This species is much smaller than the former, and it is also more lightly made, and more active, found at more places of the coast, and more constantly there. The action of the shag upon the water, on a fine breezy day, when the smaller fishes are near the surface, is very amusing, and even graceful. It floats with wonderful buoyancy in the air, twitches down to the water with the rapidity of lightning, and sometimes passes clean through the unbroken surge, and appears upon the wing on the other side. The shag is subject to considerable varieties in size ; and, as the young are without the crest, and 140 CORNER— CORVUS. the old ones lose it in winter, we generally find the shag1 and the crested shag described in the books as different species. There is, however, every proba- bility that they are the same. Besides size and colour, the most remarkable difference between the shag and the cormorant consists in the number of feathers in the tail, which are only twelve in the shag, and fourteen in the cormorant. The tail of the shag is also larger, more wedge-shaped in the general outline of the end ; it is also more graduated (ctugee\ that is, the ends of the feathers appear like a succession of steps, as they do in the tail of the magpie. The size, as we have said, varies, but the longest of them that have been measured is about two feet six inches in length, three feet eight inches in extent of wing, and weighs nearly four pounds. The shag is very abundant in the regions of the arctic circles, and* is a bird of passage in the eastern countries of Europe. It has much the appearance and manners of the preceding, although the two species are not observed to consort. But they are alike greedy and voracious, and after having overgorged themselves, they are often found on shore in a drowsy and torpid state ; but when the torpor is over, they appear again on the water, where they are extremely alert, and not easily shot, as they dive the moment that they perceive the flash of a gun, and take care afterwards to keep out of its reach. In swimming they carry their head very erect, while the body seems nearly submerged. From the circum- stance of their feathers being not quite impervious to water, they do not remain on that element very long at a time, but are frequently seen flying about, or sitting on the shore, flapping the moisture from their wings, or keeping them for some time expanded, to dry in the sun and the wind. They nestle in the clifts of rocks, or in trees, the female laying two or three whitish eggs, much elongated, and of nearly equal dimensions at both ends P. Sinensis (the Chinese Cormorant). The tail of this species consists of twelve feathers, like that of the shag, and it is described as being intermediate between that bird and the common cormorant. It is blackish brown on the upper part, whitish, and spotted with brown, beneath, and the throat white. The irides are blue, the bill yellow, and the feet blackish. This is the Leut-ze of the Chinese, who instruct it in the art of supplying its owner with fish. On a large lake, Sir George Staunton and his party saw thousands of small boats and rafts, on each of which were ten or a dozen of these birds, which, at a signal from the owner, plunged into the water, and returned with fish of a large size. They appeared to be so well trained, that it did not require either ring or cord about their throats to prevent them from swallowing any portion of their prey, except what the master was pleased to return to them for encourage- ment and food. There are many species or varieties of cormorants in different parts of the world, especially in the south, but their habits are everywhere nearly the same. CORNER— The cornel family. "A natural order of dicotyledonous plants, containing five genera and twenty-six known species. It is closely allied to CaprifoliaceeE, and is by many botanists considered as belonging to one of the sections of that order. It differs, however, in its valvate aestivation, the number of its stamens, its single style, its drupaceous fruit, and its fleshy albumen. By the same characters it is dis- tinguished from the order IlamamclidctE, to which also it bears an affinity. Its essential characters are : tube of the calyx adnate with the ovary, limb four-lobed ; petals four, oblong, broad at the base, inserted on the top of the tube of the calyx, regular, with a valvate aestivation ; stamens four, inserted along with the petals, and alternate with them ; anthers ovato-oblong, two-celled ; style filiform ; stigma simple ; drupe baccate, crowned with the limb of the calyx ; seed pendulous and soli- tary ; albumen fleshy. The plants belonging to the order arc : trees or shrubs, rarely herbs, with opposite, entire or toothed leaves, and capitate, umbellate, or corymbose flowers. They are found both in the cold and warm regions of Europe, Asia, and America. The genera of the order are : Cornm, Aucuba, &c. Cornux sanguined, wild cornel tree, dogwood, grows commonly in Europe and in the northern parts of Asia. It is likewise found native in Britain. It bears greenish white flowers having an unpleasant smell. Its berries arc of a dark purple colour, and like every other part of the plant are very bitter. An oil has been obtained from them which has been used for lamps. The bark of the older branches is dark-red, and the leaves assume this colour before they fall. The wood is hard, and makes good mill- cogs, bobbins for lace, tooth-picks, &c. It also furnishes excellent charcoal which is used in the pre- paration of gunpowder. Cornus florida, American or Virginian dogwood, generally attains the height of twenty feet, with a diameter of four or five inches. The flowers arc small, of a yellowish colour, and are surrounded by a large involucre, composed of four white floral leaves. This involucre constitutes all the beauty of the flowers. The wood of the tree is hard, compact ami heavy, and is susceptible of a fine polish. It is used by carpenters. The inner bark of this arid another species, Cornus sericea, is bitter, and is often used in North America as a tonic. In the United States, these barks are frequently prescribed for the cure of intermittent fevers. The young branches of the former species, when stripped of their bark, and rubbed with their ends against the teeth, render them extremely white. A good scarlet colour is obtained from the bark of the more fibrous roots. Cornvs Succica, dwarf-cornel, is found in Europe, the northern regions of Asia, Kamtschatka, Greenland, Lapland, and North America. It in also met with abundantly in mountainous pastures in Scotland and the North of England. It is a herbaceous plant, from four to six inches high, bearing an umbel of dark purple flowers. Its fruit has a red colour and a sweetish taste, and is used in the Highlands to create an appetite. The other genera of this order do not require to be particularly noticed. CORVUS (Crow, or perhaps, in the more ex- tended sense, Corvido!, the crow family), a very numerous, widely extended, and well-known tribe of birds, belonging to Cuvier's conirostral division of Passeres, and in the natural classification, or that which is founded upon the general habit in feeding, and not the mere structure of the feeding apparatus, to the order of Onimvora, or birds which are indis- criminate in their food, subsisting upon animal or vegetable matter, recent or putrid, according to circumstances, and thus being fitted for inhabiting almost every latitude on the face of the earth. C O R V U S. MI The general characters are : the bill short, more or less compressed or flattened on the sides, sharp and trenchant in the cutting edges, slightly curved towards the point, stout in its whole structure, and, though not a tearing instrument, like the beaks of birds of prey, generally very efficient both as a thrusting and a cutting one ; the nostrils are at the base of the bill, of an oval form, open, and defended by bristly hairs or stiff feathers, which project a little way forward over the base of the bill ; the feet have four toes, three directed to the front, the middle one shorter than the tarsus, the whole three divided to their base*, and one toe behind. The tarsi and toes are in general stout, and in some of the species they are provided with powerful claws, which are crooked, and serve for seizing and wounding their j prey. The wings are in general long and pointed; the second and third quills are, however, shorter than the fourth one, so that the wings are not of that form which is best adapted for turning readily in the air, and preying on the wing in that element. Cuvier, following the general organisation, both external and internal, was induced to include in the crow family three races of birds, the crows properly so called, the birds of paradise, and the rollers. Some account of the second of these will be found in the article BIRD OF PARADISE, and we shall give some notice of the last in the article ROLLER ; so that the present article will be restricted to the crows properly so called, though strict systematists divide them into several genera, more certainly than are required for popular services, and probably more than strict science would warrant. There is no question that Cuvier's union of the three races which have been mentioned into one group is warranted by the general organisation ; and it is equally true, that those who form arrangements upon external differences, without any regard whether these differences go farther than the mere surface or not, may make many subdivisions of a race so numerous, so widely distributed, and subjected to so many differences of food and climate as the crows unquestionably are. But, if we are to view the pro- ductions of nature in a popular sense, that is, in that sense in which they are calculated, with the least labour on our part, to throw light upon the natural usefulness of each other, we must adopt something like a middle course, so as neither to group too largely, nor to subdivide too minutely. Now, when we look at the three great divisions of which Cuvier forms the group, we find that each of them has, as it were, a different place in nature, is regulated by, or under, the controul ot circumstances different from those which regulate the others, although we cannot always say distinctly what those circumstances are, or how they operate. We find, however, that the birds of paradise are confined to a very peculiar situation on the globe, namely, the isles to the south-east of Asia, which have their climate, their seasons, and the greater part of their natural productions, peculiar to themselves, and not to be met with in any other part of the world. The rollers are not so confined or peculiar in their geographical distribution, but still they are found only in temperate latitudes, and in places which are well wooded and rich. Neither of them is, therefore, a race of birds which we can take along with us in our general tour of the world, or rather, which we do not need to take along with us, as in one or another of their species we find them in every clime \vhich we can visit. They are in the extreme north, in the middle latitudes, and also in the extreme south, and they are thus generally distributed always in propor- tion as they are more decidedly typical of the order. It is possible for a European to go where he can claim acquaintance with hardly one vegetable production, with few mammalia, few birds, and few fishes, and even where his own species seems, in appearance, in language, and in manners, more strange to him than any other inhabitant of the earth, even where the greater part are comparatively new. But a crow, and especially a raven, is instantly recognised as an acquaintance wherever it is met with, so that its appearance puts man in mind of his home, even though it is at the Antipodes ; and, if there were no other charm about the birds than this universal memory which they afford, it would be sufficient to recommend them to our grateful notice and our careful study. Generally speaking, the genus Corvus are all sober, and even sombre in their attire, but there are a few exceptions ; and even in the most dull garbed ones there is a beautiful compactness in the plumage. Their feathers appear to be better tempered to the elements than those of almost any birds, and thus they are enabled to keep very constantly stirring and beating about on the wing ; so that, though many of them are remarkably social in their habits, firmly attached to the same places, and returners to their habitual dwellings every night, yet, taking them altogether, they range more in search of their food than almost any other birds ; and, as they are more generally distributed over the globe than most birds, so they are more spread over individual countries, notwithstanding that there is a certain kind of locality which each species appears to prefer to every other. It is not a very easy matter to judge of the relative degrees of what we call sagacity or wisdom in birds, neither is it very easy to speak upon the subject without some chance of falling into error, because the inexperienced animal is just about as wise as the experienced one, and thus their wisdom, or whatever else we may call it, has a different origin, and is of a different nature, from that which is accounted wisdom in us. But still we cannot help comparing the degrees of this animal's sagacity as they display themselves in different animals ; and it is not the less valuable to make these comparisons, that we do not know the nature and origin of that which we thus compare. The fact is, that this comparison of one degree with another, without any primary standard, is far more general than its op- posite. When we say degrees of heat, of light, of moisture, of growth, or even of magnitude, we do not speak in terms of an absolute standard — we merely mention observed differences ; and if we do this in the case of mere physical existence and its attributes, we cannot reasonably hope to be better informed, and more at home, when not merely life, but the degree of sagacity connected with life, is the subject of inquiry. Estimating them in this way, we may say, with no small degree of confidence, that the crow tribe are the most intelligent of birds ; and when we consider that they are, in one or other of their species, cast upon the world generally for their means of support, instead of being confined to those places where a peculiar food for them is produced, we 14-2 C O R V U S. illicit expect them to be possessed of this kind of sagacity. Great acutencss of senses, and what, as compared with birds which are made fur one place only, we may consider as remarkable habits of attention and observation, are necessary for this purpose ; and accordingly, we find that these are possessed to an extent of which we have very few instances in birds, and of which it is not very easy for us sometimes to discover the nse. There is certainly a perception of brilliancy of colour in these birds, and they make an election between substance and substance upon this principle alone, for which it is difficult to account upon any notion that we have of the supplying of their animal wants. Thus, for instance, if there are two little pieces of potter's ware, of the same size, shape, and consistency, and if the one side of them, as is often the case in coarse brown ware, be white and glazed, and the other not, if they are left in a magpie's way, one with the glazed side upward, and the other with the unglazed, the chance is, that the magpie will carry off the glazed and shining one, but certainly no: the other; so also, if a shilling and a halfpenny are left in the way of the same bird, the shilling will likely be carried off, and the halfpenny left. If we were to argue this last election upon the principle of experience, or cause and effect, as those principles regulate our conduct, we should be apt to conclude that the magpie is not only fond of money, but a judge of the value of it. This cannot, however, be the case, inasmuch as, in times of her greatest famine, the magpie never thinks of fetching from her store of cash, or other valuables, wherewithal to purchase food, but beats the bushes with the same assiduity as if her coffers were empty. The fact is, that these birds have a very strong habit of what we must call not merely observation, but curiosity in observation — a means, though it is impossible for us to say in what it consists of, judging of the appearance of things, and selecting one in preference to another on account of appearance only, and without any reference to intermediate usefulness in the supplying of any present want. Wild or tame, we find that animals of this family are always prying about, and that they not only perceive what is immediately beside them, but have no inconsiderable degree of knowledge of what is going on in the world around them ; and though this vigilance renders them very wary of real danger, and very expert in the avoiding of it, it gives them a degree of self- possession much greater than that of most birds, and this seems to be one of the principal grounds upon which the whole race are so much more easily tamed, than from their cautious and wary dispositions we might be led to expect. In the case of most birds we require arts of taming, and in many the birds cannot be kept without the confinement of cages ; but in the case of almost any species of this genus, we have only to feed them well, and they not only feel at home, but tender us their services in doing what they can to drive off other intruders. Another remarkable quality of this, and some of the allied genera, is the great readiness with which they can be made to articulate, that is, to imitate the sounds of the human voice. This is so well known, that many people keep the birds in con- sequence of the habit they have acquired of repeating words ; and a foolish piece of ignorance is sometimes productive of a good deal of crueltv in this particular case. It is a vulgar belief, that they speak more plainly when their tongues are split, and much pain and annoyance is often occasioned to them by the performing of this operation. Now, there cannot be a piece of more gratuitous cruelty ; for every one who knows anything about the structure of birds is perfecily aware that their tongues have nothing to do in the production or the modulation of those sounds which they utter, whether natural or acquired. The organ of voice in birds is at the bronchial end of the windpipe, and whatever of articulation they give forth is generated there, though the wind-pipe and mouth may act as a sort of trumpet in increasing the volume of sound, or otherwise changing the pitch of it. Birds of this genus acquire a very considerable de- gree of interest, when we come to reflect on the part of their character now stated ; and also when we lake their usefulness into the account. Some of them at some seasons commit depredations upon the property of man, arid destroy numbers of the eggs and young of bird?, and aiso of the young of some matumalia, upon which man sets a value; but these arc nothing to the good which they do in return ; and it is doubt- ful wliethtM1, without the labours of birds of this genus, any country could lie profitably cultivated, not only in so far as concerns plants which are reared for the sake of their seeds or grains, but also as concerns the meadows which are to be grazed. In some districts of Britain it has been felt by experience that the ex- termination of rooks is any thing but a prudent mea- sure ; and, although in many districts a price is set upon the head of the raven, it is questionable whether there be much more wisdom in that. The raven is, in a state of nature, one of the most retiring of the genus, because his habits arc different from those of many of the rest ; and, therefore, as is the case with the more powerful and predatory creatures of all classes, the raven retires naturally from those places where he is not immediately wanted. In the rich agricultural districts, and the wholesome and abun- dant sheep-walks, where all the stock is in good condi- tion and free from disease, the raven levies no contri- bution, except upon such members of wild nature as do not fully participate in the benefit of man's culti- vation, and, indeed, he seldom makes his appearance at all. It is generally said, in places where ravens are abundant, and where their manners should be best known, that among domestic animals, even in their young and helpless state, the raven scents no- thing but disease. Now, it is well-known that in countries which are poor, badly cultivated, and sub- ject to great variations of winter weather and winter feeding for domestic animals, those animals are not only liable to become diseased in the spring mom Is, but many of their diseases very speedily infect the rest, till mortality becomes very general. These dis- eases, when they come to the infectious stage, are generally diseases of the alimentary canal, and before they come to this stage, the muscular strength is gene- rally so far subdued that if they are out of doors at pasture, the diseased ones are not able to accompany the healthy, or even to rise up when they have lain down. It is in this stage that both sheep and cattle in exposed situations become ravens' food ; and, in- deed, in which they attract the notice of these birds ; and when they attack calves or lambs, it will gene- rally be found to be those that have been dropped by weakly mothers which are incapable of rearing them. C O R V U S. 143 Thus, it will be found upon examination, that in most cases where there is a raven's portion, and a raven to take it, there is more advantage to what remains in its being so taken, than if it were left. We might easily go over the whole list of these Corcidte, of which the habits are known with any degree of certainty, and show in a similar manner that, in a natural point of view, and even in reference to man's artificial modes of culture, they all do good, and not evil ; but the limits within which we must confine this part of the subject, forbid us from saying any more, however in- teresting it might be to follow up the details. We shall, therefore, only farther mention the leading cha- racters of a few of the principal species, taking those first which are best known in our own country, and commencing with the more powerful ones. Connts corax (the raven) is the largest and most powerful of all the species, measuring fully two feet in length, at least four feet in the stretch of the wings, and having the tail very firmly feathered, and equal in length to half the body. The plumage over the whole body is black, but glossed with blue reflections, which in certain lights give a very peculiar colour, which is known by the name of raven-grey ; and in the extreme north the tint is apt to become paler than it is in warmer climates, and sometimes occasions the description of the bird as two species, whereas all over the world it appears to be the same, without any thing that can be regarded even as a variety. The raven lives in the wilds rather than in the woods, though it nestles in the latter, and builds at a very considerable elevation ; and even on the ground, when it does not find other places which are better suited to its habits. When it has a proper choice, however, it prefers the ledges and clefts of rocks, not so high up. or in general in so exposed situations as those in which the eagle builds her eyrie, but rather on the margin of the cultivated grounds, or at all events in places where the vicinity affords plenty of food for it and iis brood, which are very clamorous for their meals, and very voracious in the devouring of them. The gape of a young raven is very ample. The nest is funned externally of sticks, and lined with various matter?, such as wool or hair. The eggs vary in number, rarely exceeding five, and being very often not more than two. They are of a sort of oil-green colour, with some markings of brownish ash. Ravens are very attentive to their young and the old ones, which are understood to pair for life, that is, while both live — for no birds remain in widowhood, but pair again (if they can) when the season conies round — are very much attached to each other ; they are never far apart, and if danger overtakes the one the other gene- rally makes its appearance, and is not slow at giving assistance. The wariness of the raven makes it very rarely a prey to the stoop of the eagle, or the stroke of the more powerful falcons ; and, at close quarters, these are not more than a match for the raven, if, indeed, they are as much. In some cases which have come within the knowledge of the writer of this article, a trained falcon (a peregrine, not a jer) has struck at and clutched a raven, but the raven so returned the clutch that, if assistance had not been given, the falcon would never have struck another bird ; for, between the two, it appeared to be very equally " claw for claw," as the saying is, and it is doubtful whether, if human aid had not come to the falcon, the two would not have been found dead together. In former times ravens were by no means rare birds, in many, indeed in most parts of the British islands, and in various parts of the country, there was an alle- gorical saying, " every rock has its raven," but they are now comparatively rare in England and in the south of Scotland, though there are some in even the eastern parts of the highlands, and more in the west highlands and the isles, where, in consequence of the greater abundance of humidity, and the consequent superiority of growth and abundance of life, they are by no means rare. From the first ridges of secondary hills at the south side of the base of the Grampians, there is, indeed, no want of ravens in most of the waste places, except in the more bleak and uninteresting moors, where there are no spots within many miles properly adapted for being their nesting places. In that part of the country they seldom if ever build in trees, because the principal woods there consist of pines, in which there is not much game suitable for the raven. But in the high and rugged rocks, espe- cially when they have a southerly exposure, and copses and rich patches of land at the base, they are never wanting. In ravens' weather, that is, when the sky lowers and portends storms, or after the storm has just passed, they may be seen upon the more open parts of the woods, sitting on a dark mass of stone and eyeing the desolation around them with keen and cautious glance ; and they sometimes vault up to a considerable height, and scan the wide and wild land- scape from the top of the sky. They are not the most abundant of the crow tribe which we meet with in these lonely places, and they are not so social or so lively in their manners as most of the others ; neither do they, in all probability, commit so many depreda- tions on the nests and young of those birds which breed in the heaths and upland morasses as some of the others. But when you pass near those rocky places which are their favourite haunts and hiding places, it so happens that though you do not always see the raven, the raven always sees yon; and he will steal along, by the side of your route, in the tractless desert for many miles, though when you get a sight of him, he appears always to be leaving you, and hop- ping away to a place in which he himself may be safe. This is done most readily and habitually when there is no sun, and the whole scene wears the dusky hue of the raven. And, though he appears to be always on the retreat, if you sit down vou will soon find him H4 C O R V U S. perched on some stone, with his tail towards you, but with the head turned back, and attending with the ut- most watchfulness as to whether you are or are not in motion. If you make any demonstration against him, he will get on the wing with much apparent pain and difficulty, and seem as if he were marching off; but he has a curious way of "sideling" on the wing, by means of which he moves in the lateral direction, and gains on you at the end of his flight, even although he has seemed to be retreating all the time. If you wish to watch his manoeuvres in the most perfect man- ner, or to tempt him within the distance of a shot, the best way is to lie down at full length on your back, and remain motionless. In such a case, if he is at a long distance when you take up your position, he will gain considerably on the wing, by more bold and de- rided flight than if you are merely sitting. But under no circumstances will he use the wing for the full ex- tent of his reconnoissance ; he will alight at a consi- derable distance, and even if you are so motionless that he feels confident of making a prey of you, he will still approach you in perfect conformity with the tactics of a siege, never upon the direct line, but at an angle, working by traverses more and more oblique as he comes nearer, so that when you observe him in motion, he is always as if he were passing by and re- garding you with a mixture of fear and wonder. When he turns at the end of his traverse he stands for a short time as if he were irresolute, and at a loss which way to go, and seems studiously to avoid any appearance of design in his movements. But if you remain quite motionless, he will come very near ; and should you allow yourself to doze during his crafty approach, the chance would be that your awaking might cost you an eye ; and thus it is better for you to " have an eye" upon him. If you are provided with fire arms, and are inclined to add the useless carcass of a raven to the museum on the barn wall or the stable-yard at the inn, you may, if you have patience enough, make sure game of him ; but if you fire and miss him, or if you start up when he is very near you, he mounts the sky, soon clears your horizon, and though you wait ever so long you see him no more. The raven, when taken young, and the young, in consequence of their clamour, are easily discovered and procured if the nest is accessible (and when it is not, they often fall headlong and are found yelping in their discordant tone among the bushes), is easily tamed, and may be turned to account both as a scavenger and a watchman about tan-yards and other places where there is offal calculated to attract strangers. When these approach, the raven "gives tongue," or rather throat, and if they venture upon his ground, he appears to hop away with one of his legs crippled ; but, watching his opportunity, he contrives to jerk himself, like a dart, at the enemy, and as his bill is both strong and sharp, a blow of it will send off a large cur howling. These tame ravens take fancies to, and against, persons, and other animals, for which it is by no means easy to account. Without any apparent difference of treatment received by them- selves, they will welcome one party, appear to play with them, and never offer any violence ; while there are others that they will strike and bite with great bitterness, even when they are fondled, Ravens, though so voracious, that their name has been generally applied to all who are greedy of food or of any thing else, and not over nice as to the means by which they procure it, are capable of bear- ing hunger for a very long time. They are so hardy that even in the wildest places, and those where they are most abundant, a dead raven, unless one which has been killed by man, is a very rare sight. They are also understood to be very long-lived, but the number of years is not ascertained. They must, how- ever, be subject to some casualty, as the increase in numbers, in proportion to that of the eggs, is very small. There are ravens in most quarters of the world, if the state of the country is suitable to them, and there is little climatal difference, further than that those which are found in the high polar latitudes are pale in the colour. We may farther mention as distinguishing features of this species, that the tail is very much rounded ; that the feathers on the throat are narrow, sharp pointed, and raised ; that those on the back part of the neck are soft and silky ; that the bill and feet are black, and that the irides of the eyes consist of two circles of colour, the outer brownish, and the inner pale smoke grey. Corvus coronc, the carrion crow, or common black crow. This species is much smaller than the raven, being only about twenty inches in length, twenty-six in the extent of the wings, and eighteen ounces in weight ; and as birds, to be equally well winged, should have the wings in the proportion of the cube-roots of their weights, it is not, in proportion, a bird of so powerful flight as the raven. The plumage of this species is entirely black, with few or no metallic reflections, or with them, of a dull green colour; the feathers on the throat being small and narrow, and the webs, toward | their points, loose and flocculent ; and the tail not so t much rounded as that of the raven. Still, the bird I has more the air of the raven than that of any other ' of the family, so that it may, except in colour, pass i fora miniature of that bird, with the exception of the I gloss of blue on the upper part of the true raven. The carrion crow, as its name imports, is a foul and miscellaneous feeder. No garbage comes amiss j to it, however rank ; and it is by no means shy in the i search of the offal of all sorts. For these reasons it is sometimes called the "dung-hill" crow, and, in Scotland, the "midden" crow; and it is the crow, throughout England. It is very generally distributed ; but as the individuals are not in the habit either of flocking on their pastures, or of assembling in numbers to the same herding places, they do not make the same appearance as some of the other members of the genus. Carrion-crows nestle in trees, generally in more retired places, and farther apart from each other than rooks. They generally pass the summer in extensive forests, from which they occasionally emerge to pro- cure subsistence for themselves and their infant brood. They feed on flesh, eggs, worms, insects, and various kinds of grains; but they are particularly fond of carrion. In spring, they greedily devour the eggs of partriges and quails, and are so dexterous as to pierce them and carry them on the point of their bill to their young ; even fish and fruit are not unsuitable to their palate. They often attack the eyes of dying animals, destroy weakly lambs, and, when pressed with hunger, will even pursue birds on the wing. They are noto- rious for the havoc which they occasion among game and poultry, and in rabbit warrens, where they kill and devour the young. When hens lay their eggs in hedge bottoms, or farm-yards, crows are often caught in the act of devouring them ; but when they happen C O It V U S. 145 to be satiated, they will frequently hide their food till hunger becomes more urgent. They have been observed to ascend with a crab to a considerable height and let it fall on a rock to break the shell, and then instantly pounce down upon it and bear it away for immediate consumption. In like manner, a friend of the late Dr. Darwin saw, on the northern coast of Ireland, above a hundred crows preying at once on mussels which they despatched by a similar process. Near the Cape of "Good Hope they have been seen to dispose in the same way of land tortoises. We read too of an ill-starred philosopher, in ancient times, who was killed by an oyster impinging on his bald •pate,, which a crow had mistaken for a block of stone. During the winter, these birds consort with the rooks and hooded crows, and sometimes intermingle with the latter, so as to give rise to a hybrid race. In this season, numerous flights of various species of the first genus assemble about our dwellings, keeping much on the ground, sauntering much about the flocks and shepherds, hovering near the tracks of thelabourers, and sometimes hopping on the backs of pigs and sheep, with such apparent familiarity, that they might, be mistaken for domestic birds. At night, they retire into the forests to lodge among the large trees, resort- ing to the general rendezvous from every quarter, sometimes from the distance of nine miles all around, whence they again sally out in the morning in quest of subsistence. As long as this association lasts, the hooded and carrion crows nre observed to grow very fat, while the rooks continue always lean. To- wards the close of winter, the latter also remove into other regions, whereas the carrion crows resort to the nearest large forests, where they pair, and seem to divide their territory into districts of about three quarters of a mile in diameter, each of which is allotted to the maintenance of its appropriate family, an arrangement which is said to subsist inviolate during the lives of the separate parties. The female lays from four to six eggs, of a bluish green, and marked with large and black spots, of cinereous grey and olivaceous , and weighing about five drachms each. She sits about three weeks, during which time the male supplies her with food. The carrion crow often wages war with the lesser species of hawks ; but it is especially courageous in the breeding season ; nor will it suffer the kite, buzzard, or raven, to approach its nest with impunity. The young do not finally break off connexion with the parents till the commencement of a new brood. As they naturally attack small game, when wounded or exhausted, they have, in some countries, been bred for falconry, as in Turkey, where gentry of inferior quality paint them of different colours, carry them on their right hand, and call them back by the frequent, repetition of the syllable hoob. Although their flight is neither easy nor rapid, they generally mount to a very great height, and indulge much in a whirling motion. Their croaking in the morning is said to indicate fine weather. As they are exceedingly cunning, have an acute scent, and commonly fly in large flocks, it is difficult to get near them, and still more so to decoy them into snares. Some of them, however, are caught by imitating the screech of the owl, and placing limed twigs on the high branches of a tree ; or they are drawn within gun shot by means of an eagle-owl, or such other nocturnal bird, raised on perches, in an open spot. They are destroyed too, by throwing to them garden beans in NAT. HIST.— VOL. II. which rusty needles are concealed. They arc like- wise caught by cones of paper, baited with raw flesh. As the crow introduces his head to devour the bait, which is near the bottom, the paper, being besmeared with bird lime, sticks to the feathers of the neck, and he remains hooded ; unable to rid his eyes of the bandage, he rises almost perpendicularly in the air, the better to avoid striking against any thing, until, quite exhausted, he sinks down, always near the spot from which he mounted. These, and other modes of ensnaring crows, are chiefly practised in the winter season, when the ground is covered with snow or bound up in frost, for then they more readily approach human habitations, and seek to pick up some subsist- ence from the dung of animals that have passed along the highways. But many of them are killed, at all seasons, in various parts of the continent, by strewing overthe grounds which they frequent, pellets of minced meat, mixed with the powder of nux vomica. The carrion crow appears to combine the disposi- tions of two or three other species of the genus. In form, in colours, and in its predatory habits, it resem- bles the raven , in restlessness and disposition to hoard, it has considerable analogy to the jack-daw ; and in the last of these particulars, as well as in its general cunning, it has some traits of the magpie. It follows the general habit of the whole race in being easily tamed, and taught to repeat words without much difficulty. But still, it has peculiar characters, and belongs to a certain description, or a certain state of countries. It is not a bird of the perfect wilderness, an inhabitant of the open moor or the cliff; neither is it most favourable to those places which are in a high state of improvement. Wooded tracts, which arc rather warm and fertile, but somewhat in a state of nature, are the localities in which it is most abundant; and if we are *o assign it a topographical position, we may say, that its locality is intermediate between that of the raven and that of the rook. The raven, the carrion crow, the hooded crow, and the rook, may be considered as the typical crows, at least in Europe , and their localities are, the hooded crow, the raven, the carrion crow, and the rook, gradually approaching nearer the cultivated grounds. Corvus comix, the hooded crow, or, in some parts of the country, the " hoody." This species is con- siderably larger than the black crow ; being about twenty inches long, forty in the stretch of the wings, and upwards of twenty ounces in weight, so that, with the exception of the raven, it is the largest of the crow tribe found in the British islands. Its localities are more peculiar than those of many of the others, but it is very generally distributed over the globe, and in some places of almost all latitudes it is the crow. In England, with the exception of some of the moors in the north, it is a winter visitant, not making its appearance before October, and departing in the spring. But in the north it is much more common, and continues all the year round. In the Lowlands of Scotland it is rather rare, though not quite unknown in any district ; but in the Highlands, beyond the line of regular cultivation, it is almost the only crow that is known, with the exception of the raven. It is a strong bird and a powerful flier, and ranges over the moors and mountain bogs, levying very heavy contributions on the nests and young of ground birds, which breed in those places ; and when the snow is on the ground, so that it finds but little food irdand, it resorts to the shores of the sea m.d K C O R V U S. picks up whatever it can find in that all-producti\<> locality. It is easily known by its colour, which is smoke grey, with the exception of the head, throat, wings, and tail, which are black, with reflections of a green colour, but more inclining' to blue than those of the black crow It is the contrast of the black on the head with the grey on the back which procures for this species the name of the hooded crow. The hood is not so conspicuous in the female as in the male, because the black is not so deep nor the grey so pale ; but the common opinion that the female is without the grey is not correct. The bill is black, but rather paler at the tip, strong and arched in the culmen, bearing a considerable resemblance to that of the raven. The feet are also black, the skin of the tarsi being plated. In the grey parts the shafts of the feathers are black, and the grey is subject to considerable varieties of shade, depending, in part at least, on the latitude and the season ; and albinos, or at all events, specimens in which only the shafts of the principal feathers are black, are occasionally to be met with. Though this species appears in England only in the winter, it is not to be considered as a regular climatal migrant retiring from the northern latitudes during the winter ; for it winters as far to the north as the Faroe Islands, and the isles on the coast of Norway, where the shores remain clear of ice during the winter. Those which resort to England and other champaign countries of Europe, where they do not remain during the summer to breed, must there- fore be considered as driven from the wilds of Lap- land bv the want of food. The resort of ground building birds to these wilds during the summer is very great, and hooded crows find an ample supply of provisions in the eggs and callow young ; but when the snow falls, or there is not scope and food for them all on the sea-coast, numbers seek their way to more southerly climates. But it must not, on the other hand, be considered that these birds have any partiality for northern lati- tudes, other than that they find food plentiful there in the summer season ; for they are very generally distributed in all places where there is food for them ; and they are the common, or at all events the most frequently seen species of crow in many parts of India, especially in the wild districts near the Runn of Cutch ; and we may remark that, generally speak- ing, where hooded crows remain in large numbers to breed, in whatever latitude it may be, carrion crows and rooks are rarely to be met with. The absence of timber, in such collections as to admit of rookeries, and of such closeness as to hide the nest of the carrion crow, may be partly the reason of this ; but still it is doubtful whether it will account for the whole differ- ence. The hooded crow is, for instance, the only crow known in the Shetland and Orkney Islands, and in those wild districts both of the highlands of Scotland and of Ireland, where there are no timber trees ; but there are also well wooded districts in the highlands, in which, though hooded crows are abun- dant, not a single rook or carrion crow is to be seen, though in the lowland districts, distant only a few miles, rooks are abundant, and hooded crows appear only as stragglers. A person passing for the first time from the land of rooks to that of hooded crows, which is nearly synonymous with passing from the country of lowland Scotch to the country of Gaelic, is apt to imagine that tne crows speak a new language a< \\ (-11 as the people ; for the sound of the ruuk, if not musical, is at least loud and clear, while that of the hooded crow is at once hoarse and feeble, as if it were a jackdaw attempting to mock the croak of a raven. Where opportunities offer, the hooded crow breeds in the pines and other large trees, in default of which it nestles in the cavities of rocks. The female, which is rather smaller than the male, and of less lively hues, usually lays four, five, or six eggs, of a greenish blue, marked with many spots of blackish brown. It pairs during the whole of the breeding season, and both parents are much attached to their offspring. They are remarked for their double cry, of which one is hollow and well known, and the other shrill and somewhat resembling the crowing of a cock. When other food is wanting, they will eat cranberries and other mountain fruits ; in open fertile countries, they live much on grain, worms, and carrion ; but they often resort to the sea shores/and prey on the various animal matters thrown up by the tide. Frisch observes that they are expert at picking fish bones, and that when water is discharged from ponds they quickly perceive the fish which are left in them, and lose no time in darting on them. They not only attack the eyes of lambs and diseased sheep, but of horses that have got entangled in bogs. In the Faroe Isles, where they abound, they are particularly mis- chievous, picking the seed from the fields, digging up the newly-planted potatoes, destroying the barlev before it is ripe, and carrying off goslings and duck- lings, or the fish which is hung up to dry, to their young. Corvus frugilegus (the Rook). This species, which is to the inhabitants of well cultivated countries the most interesting of the whole genus, is about the same length as the hooded crow ; but it is lighter made, and, when full grown, rather longer in the wings. Its bill too is of a character entirely different, being nearly straight, and having much less of the predatory character than that of any of the three species which have been mentioned. Its bill is bluish black, with a portion of the skin at the base bare of feathers in the full-grown birds, and covered with a scaly scurf of a whitish colour; but in the younir birds this portion is covered with feathers, which an; projected a little way over the base of the bill. The whole of the plumage is black, but glossed with re- flections of purple, violet, and blue, which are very rich and beautiful when the bird is in good condition. The legs and claws are also generally of a black colour. Sometimes, however, but not very often, these birds are subject to variations, not only in the plumage, but in the bill, the claws, and the naked skin. Some are pure white, others piebald, others yellowish, and in these cases the bill, feet, and claws, are generally of a flesh red, but there is always a trace of darker colour in the principal feathers of the wings and the feathers of the tail. Specimens which have these varieties of colour cannot be considered as permanent varieties, and they do not perpetuate their colours in their proareny, neither is it known whether they breed, though it is presumed that they do not. These variations are very rare, compared with the numbers of the birds; and their cause is altogether unknown. The rook is a native of most of the temperate regions of Europe, but is not found much farther north than the south of Sweden, where it breeds, but from which C O R V U S. 147 it is driven by the severity of the winter. In Russia and the tf est of Siberia, it is far from rare, emigrating- early in March to the environs of Woronetz, and mingling- with the common crows. In England they are stationary, but in France, Silesia, and many other countries, most of them are birds of passage. In France they are the forerunners of winter, whereas in Siberia they announce the summer. Their flights are sometimes so dense as to darken the air, being frequently joined, not only by the common crow and jackdaw, but also by troops of starlings. Every spring they resort to breed on the same trees, prefer- ring the loftier branches, and building sometimes ten or twelve nests, which are one above another on the same tree, whilst a great many trees thus furnished occur in the same forest, or rather in the same district. They seek not retirement and solitude, but rather settle near our dwellings. When a pair are employed in constructing the nest, one remains to guard it, while the other is procuring the suitable materials ; for otherwise the structure would, it is alleged, be instantly pillaged by the other rooks which have fixed on the same tree, each carrying oft' a twig to its own dwelling. Rookeries are sometimes scenes of violent contests between the old and the new inhabitants, whether the intruders be of the same or of different species. A pair which had in vain attempted to establish themselves in a rookery at no great distance from the Exchange of Newcastle-upon-Tyne. having been compelled to abandon their purpose, took refuge on the spire of that building ; and though con- stantlv interrupted by others of their own species, succeeded in completing their nest at the top of the i vane, and reared their young, apparently regardless of the noise of the people underneath. The nest and its inhabitants were in course turned round by every change of wind, and yet the parents persevered in maintaining the same position for ten years, when the spire was taken down. As soon as rooks have finished their nest, and before they lay, the male besrins to feed the females, which receive their bounty with a fondling tremulous voice, fluttering wings, and all the little blandishments that are expected by the young while in a helpless state. This gallant deport- ment of the males is continued through the whole season of incubation. The female lays four or five eggs, which are smaller than those of the raven, but marked with broader spots, especially at the large end. After the young have taken wing there is a general deserting of the nest trees, but the families return again to them in October to roost, and to repair their dwellings. On the approach of winter, however, they usually seek some more sheltered situation at night, but generally assemble first in the usual place, and then fly oft' together. Their autumnal exercises of departing on their foraging excursions in the morning, and returning in the evening, are familiar to ordinary observation, and have been well described by White and others. Though the forest may be said to be their winter habitation, they generally visit ilicir nurseries every day, preserving the idea of a family, for which they begin to make provision early in spring, the business of nidification being usually accomplished in the month of March. The rook has but two or three notes, and makes no great figure in a solo ; but when he performs in con- cert, which is his chief delight, these notes, though rough in themselves, being intermixed with those of tue multitude, have, as it were, their ragged edges worn oft', and oecome harmonious, especially when softened in the distant air. So marked is their dread of a fowling-piece, that the country people allege they even smell gunpowder ; but, if the gun be carefully concealed from their view, a person with his pockets full of gunpowder may approach very near them. Among the favourite articles of their food is the grub of the chafer, or beetle, which, if allowed to multi- ply unchecked, would lay waste whole meadows and cornfields. It must not be dissembled, however, that rooks themselves are sometimes very injurious to new sown wheat, just when it begins to germinate. The severity of winter, when accompanied by a heavy fall of snow, sometimes drives them down to the sea-shore, where they are observed to feed on small shell-fish, particularly the common periwinkle. Having raised these last into the air, to about the height of fifty feet, they let them fall among stones, stooping instantly after their prey. If the shell is unbroken, they lift it again and again ; and when the wind happens to carry it out of the perpendicular direction, they toil much and gain little. Frauds in the mode of procuring their livelihood, as well as in that of building their nests, are sometimes attempted among them, but which, when discovered, meet with instant and condign punishment. Indeed we can scarcely doubt that these sagacious birds have ideas of property, unknown to many of the inferior animals, as each pair, year after year, assert their claim to the same nest ; and an at- tempt to invade them, on the part of others, would, as often happens, be punished not merely by the ag- grieved individuals, but by the combined efforts of the society, which clearly proves that they consider it as an offence against the community. When tamed they evince both confidence and attachment. The young of this species are, by some, reckoned good for the table, but those habituated to better fare will probably esteem them somewhat coarse. In order to be at all edible, they must be skinned, and, even then, they are exceedingly bitter, and not very nourish- ing ; but the abundance in which they may be had where there are extensive rookeries, renders the shoot- ing of them when they are " branched," that is, when they have left the nest but not taken to the wing, rather a favourite exploit with the more humble de- scription of sportsmen. The sport is, however, both cowardly and cruel, not greatly superior to that of shooting pigeons from a trap ; and the lamentations which the parent birds make over their slain progeny are not only painful to hear, but have a very strong expression of reproach in them ; and the feelings thereby produced are not lessened when we consider the perfect confidence with which rooks congregate near human habitations, and the great services which they render to the cultivator. Corvus monedu/a, (the Jackdaw), or steeple crow, called in Scotland the kae, which is very nearly the sound of its natural voice. It is about fourteen inches in length, twice as much in the stretch of the wings, and weighs about nine ounces. The head is black, the nape of the neck is smoke grey, the back greyish black ; the wing-coverts and secondary quills black, with violet reflections ; the under part bluish black ; the bill and legs also black, and the i rides whitish grey. This species is noisy, and, when tamed, it is mischieT vous ; but in its general habits it resembles the rook, in rarely plundering the nests of other birds, but rather feeding upon insects,worms, and various sorts of se,ed<«. The jackdaw, though it affects peculiar localities, K2 148 C O R V U S. and chiefly towers in cliffs, is not absolutely confined to such places, even in its nest-building. It is also very generally distributed over Europe, stationary in some countries, but migrant in others, without any uniform regard to difference of latitude. On the extreme north of Europe it is indeed only a summer visitant, there being no food for it in the winter. In Sweden it is found pretty far to the north. It winters about Upsal, and passes the night in large flocks in ruined towers, especially those of the old town. It is common all over Russia and Western Siberia. In the south of Russia, and in Great Britain, it is stationary throughout the year ; but in France, some parts of Germany, and other places, it is at least partially migratory, though a number of them continue in these countries during summer. Such of them as migrate form themselves into large bodies, like the rooks and hooded crows, whose phalanxes they sometimes join, continually chattering as they fly. Yet they observe not the same periods in France and in Germany, for they leave the latter in autumn, and appear not again till the spring, after having wintered in France. In general they frequent old towers, ruined buildings, and high cliffs, but they also occasionally breed in the holes, and even on the branches of trees, especially if in the neighbourhood of a rookery. In some parts of Hampshire, owing, probably, to the want of towers and steeple?, they frequently build in the burrows of a rabbit-warren ; and in the Isle of Ely, from a similar cause, they take up their abode in chimneys. Their nest is made of sticks, and lined with wool and other soft materials, and the eggs are generally five or six, smaller and paler than those of the crows, of a bluish or greenish ground, spotted with black or brown. After the young are hatched, the female watches, feeds, and rears them with an affection which the male seems eager to share. Some authors affirm that they have two broods in the year, but this, we have reason to believe, is by no means uniformly the case. During the season of courtship they prattle inces- santly, woo each other's society, and even kiss. Even in captivity they refrain not from these marks of tender attachment. Many pairs usually nestle in the same neighbourhood. They feed principally upon worms and the larvae of insects, and are very fond of cherries. Their voice is shriller than that of the rook or crow, and appears to be capable of different inflexions. They are easily tamed, and seem so fond of domestication as seldom to attempt their escape. They may be fed on insects, fruit, grain, and even small pieces of meat. With no great difficulty they may be taught to articulate several words ; but they are mischievous and tricky, and will secrete not only portions of their food, but pieces of money and jewels. Corvus pica, or Pica melanoleuca (the Magpie). This is a species with lively colours, the peculiar attitudes, the prying disposition, and the familiar manners of which every body is acquainted with. Its length is about eighteen inches, but great part is taken up by the tail, and the body is rather short and round ; the extent of the wings is about two feet, and they are broad and rounded, and better adapted for ascending and descending than for long flights, upon which the bird flies with rapid movements of the wings, and apparently with difficulty. The weight is about nine ounces ; the bill and legs are black ; and the irides deep and bright brown, which gives very considerable expression to the eye. This is altogether one of the most beautiful of British birds, and if it were not so common it would be very much admired Its colours are black, with purple and green rciitr tions ; the scapulars, breast, belly, and inside of the wing-feathers, white ; tail lengthened and wedge- shaped ; the black, especially on the feathers of the wings and tail, exhibits, in certain dispositions of the light, very fine reflections of green, blue, purple, and violet, a circumstance of which superficial observers are little aware ; nor can he who has only examined a dirty specimen, in confinement, form any adequate notion of the native beauties of the bird. It is about eighteen inches long, twenty-four in extent of wing, and weighs between eight and nine ounces. The female differs from the other sex only in being somewhat less, and having a shorter tail. Among the more remarkable varieties to which it is occa- sionally liable, we may notice that of whiteness almost pure, cream or buff colour, and white streaked with black. The magpie is generally diffused in England, France, Germany, Sweden, and most of the countries of Europe ; and it also occurs in Asia as far as Japan, in China, as well as in Siberia, Kamschatka, and the adjacent islands, whence it has possibly passed into the northern parts of America, for it is seen, though rarely, in Hudson's Bay, and on the borders of the Mississippi. In Europe it is found as far north as Wardlines, and as far south as Italy ; but it sel- dom abounds in hilly regions. Being smaller than the rook, and with wings proportionally shorter, its flight is neither so lofty nor so well supported ; neither does it undertake long journeys, but only flies from tree to tree, at moderate distances ; yet it is seldom at rest for any length of time, but skips and hops about, and shakes its long tail almost incessantly. Though naturally shy and distrustful, yet it is seldom found remote from human habitations. Magpies generally continue in pairs throughout the year ; and if they sometimes unite into small flocks, it is only for some temporary purpose. They are clamour- ous and mischievous, reject hardly any species of animal food or fruits, and devour grain when nothing else is within their reach. They will prey on birds caught in snares, on nestlings, rats, field-mice, young poultry, leverets, feathered game, carrion, fish, and insects. Lambs, and even weakly sheep, they attempt to destroy, by first plucking out their eyes. They are notorious pilferers and hoarders, and will conceal either provisions, or any glittering objects, with great address, pushing them into holes until they are no longer visible. Their winter store of food is usually collected in the middle of a field, and is sometimes indicated by two of the species contending for the hoard. Though crafty, they arc also familiar ; and though naturally addicted to chatter, they are still more so when tamed and attached ; so that, especially when taken young, they may be taught to pronounce words, and even short sentences, and will imitate any singular noise. In their natural state they proclaim aloud any apparent danger, insomuch that no fox, or wild animal, can appear without being noticed and haunted ; and thus even the fowler is frequently de- prived of his sport, for all birds seem to know the mag- pie's alarming chatter. The nest, which is placed on the top of a tree, in a thick bnsh or hedge, and some- times at no great distance from the ground, bespeaks much skill and artifice. The male and female work at it C O R V U S. conjointly, or alternately, beginning in February, and usually continuing their labours for six weeks or two months. It is, for the most part, constructed on a fork, or on a junction of branches, and composed of twigs, young shoots of trees, and a thick covering of leaves, strengthened outwardly with long and flexible sticks, plastered over with mud, the upper part being covered with thorny branches, closely matted, so as to secure a retreat from other birds intruding, a hole being left at the side scarcely large enough for the admission and egress of the parent birds. The inside is furnished with a sort of mattress, composed of the fibres of roots, wool, and other soft materials, being only six inches in diameter, whereas the whole edifice measures at least two feet in every direction. Should the eggs be destroyed, the female abandons a con- struction which had cost her and her partner so much trouble, and will lay a second, and even sometimes a third time, if again disturbed, the number of eggs diminishing at each hatch. On these occasions she does not build a new nest, but takes possession of, and refits, an unoccupied one that has belonged to a rook, or else finishes one of those imperfect structures which are occasionally to be found in her neighbour- hood, as if purposely reserved fur cases of emergency. But, if unmolested, there is but one brood, which generally consists of seven or eight. The eggs are of a bluish or pale green, spotted with brown, and cinereous. The male and female incubate alternately, and in the course of about fourteen days the young are brought forth blind, and continue so for some •days. The parents rear them with great solicitude, and for a considerable length of time. During winter nights, magpies assemble in great numbers in some coppice or thicket to roost, but they separate again in the day-time. When the young are taken from the nest for training, they may be red with bread, curdled milk, or new cheese. Their flesh is considerably inferior to that of the young rook. In almost every country, the appearance of the magpie is, in the minds of the vulgar, associated with superstitious and ominous notions. The prying, pilfering-, and nest-plundering propen- sities of the magpie, sometimes subject it to a little temporary inconvenience at tiie hand? of boys, especially where it has young in a thick tree near the house. An egg is emptied of its contents by blowing, and then filled with bird-lime, and laid in some place where it may be seen by the mag-pie ; and as li Madge" has all her eyes about her, and knows most of what is within the range of her observation, the exposure of the egg out of doors is as easy a matter as the concealing of it. She soon approaches, watchful of any one who may be observing her, but intent upon the egg. After a hop or two in various directions, to see that all is safe, she dashes her bill into the egg, in the usual way of carrying the larger kinds of eirsrs to her brood ; but as the shell is already broken, the bill penetrates up to the eyes, and the shell adheres, and acts as a blind. She takes flight, however ; but, as she cannot see her way, she iiie> bumping against the twigs, and often cuts a very- ridiculous tig-ure before she can so disentangle herself from the shell and the bird-lime as to be able to see her way. When magpies are holding those councils, or " folkmotes," for which they are so remarkable, a scene of great consternation ensues among them it one of the more powerful hawks come in sight, or if a falcon is flown over them. All chattering and hop- ping is instantly at an end, unless there are bushes into which they can creep ; and when they are within reach of no such shelter, they remain motionless on the ground ; though, in places where large hawks frequently appear, they select their rendezvous in some spot which is closely surrounded by broom or furze, or some other»cover. As long as the hawk or falcon remains in sight, the whole powers of the mag- pies seem to be absorbed in the dread of it; for they may be knocked down with a stick with little attempt to escape, or taken with the hand without offering any resistance. But we must close our notice, for there is really no end of the stories that might be told of this very curious bird. Corvus glandariiis (the Jay). In some rospects the jay stands nearly in the same relation to the magpie that the carrion crow does to the rook. It is a wood- land bird, never found in open and treeless places, and very seldom near houses. In the woods it chooses the thickest shades ; and though its chatter is often heard, it is less frequently seen than almost any other bird of the same size and equally numerous. It occurs in all parts of the British islands where there is cover for it, and it has an original name both in Welsh and Gaelic, both of which have the same meaning, " wood-screecher," or " wood-screamer;" and some systematists have made it the type of a separate genus, under the name Garrulus. The jay varies a good deal in size with the nature of its haunts, being much smaller in Scotland than in England. Its mean dimensions may be taken at about a foot in length, eighteen or nineteen inches in the stretch of the wings, and about seven or eight ounces in weight. The bill of the jay is' dusky, the legs brown, and the hides of a glistening pearl grey, which gives a sharp and irritable expression to the eye. The head is whitish, with black streaks, and the "feathers on the top of the head are loose, and form a crest which is erectible at pleasure. The body is wine buff, or a mixtuie of yellow, red, and brown, so melted into each other, that the whole effect is not easily described. The lesser coverts of the wings are pale bay ; the greater coverts are marked with traces of black and rich blue. The secondary quills next the body are bay, with black tips, the next two are entirely black, and the remaining ones are black, tinged with blue, and having white on their outer necks, near the base. The rump and tail coverts, both upper and under, are white, and the tail feathers black. These birds, though they keep in the cover of the woods, are very active and very voracious. They are omnivorous, consuming great quantities of nuts, mast, wild cherries, peas, and other products of the wood and its vicinity ; they are also great robbers of the nests of smaller birds, and they sometimes kill and eat the birds themselves, and also mice, and the larger insects. They are in fact always prying about in the warm season, and very often eating. It is usually said that they are in the habit of hoarding their vegetable food against the season of want ; and it may be true, for there are a good many more birds which form magazines than we are usually in the habit of giving credit for being so provident. But, in the case of the jay, this is not easily established by actual observation, as it is by no means easy to see what they do ; and though they are found making free with a store, it cannot, on 150 C O R V U S. account of their habits, be thence inferred that this store is their own. In confinement they do conceal their surplus provisions, but they at the same time pilfer and hide substances which can be of no use to them as food ; so that no certain conclusion can thence- be drawn of what they may do in a state of nature ; and magpies and jackdaws both hoard and steal when in a domesticated state, and yet we do not hear of their stores of provisions being met with when they are in the wild state. In winter, too, at least in the colder parts of the country, jays are understood to be, for the greater part of their time, in holes of trees, or other places of concealment, in a state nearly dormant. It is not supposed that they actually hybernate, but they are rarely seen at that season when there are no leaves on the trees to conceal them ; and when they do make their appearance in winter, it is only on very mild days. When any danger appears, the jays set up a screaming, and as their chattering is loud, and they all take up the note, they alarm the whole tenants of the wood, and thus, by acting the part of sentinels, make some sort of return to other birds for the depredations which they commit on their nests. On some parts of the continent they are partially migrant, and where this is the case they partially flock, though their flocks can hardly be called societies. In Britain they are more stationary, generally remaining in the same places, and rearing two broods in the course of the season. They choose the most close and con- cealed parts of the trees for their nests ; and, both for general habitation and nesting, they prefer young woods, in which the trees are branched down nearly to the ground, to those which have tall and clean boles. Rooks and jays may be found in the same forest, but not in the same part of it. The nest is not so elaborate a structure as that of the magpie. It is broad, and rather firm, as well as carefully concealed ; but it has no dome, and is shallow, and without any very soft matters in the lining. The etrgs vary from four to seven, are smaller than those of the pigeon, of a greenish-grey colour, with olive spots. The time of the incubation is understood to last about two weeks. When the jay has grown to maturity in the wild state, it is very shy as well as cunning, and can hardly be reconciled to confinement by any means ; but when it is taken voung, it is very easily tamed, and very docile, though even then it appears at times to be very impatient of the confinement of the cage, against which it breaks its feathers, and often does itself more serious injury. But it articulates readily, can be taught a number of tricks, and therefore, in many parts of the world it is kept with much attention. Its voice is flexible, and it is capable not only of articulating words, but of imitating the voices both of other birds and of several of the mammalia. For food it is of little value, as it is both tough and of bad flavour ; but on some parts of the continent it is eaten, after having undergone the double culinary process of being first boiled and then roasted. Even if it were good, the labour of obtaining it in Britain would be far more than its value ; but on the continent it is more easily obtained ; and though it is not in request for the table under its own name, it is said to be sometimes double-cooked, as above-men- tioned, and then introduced as a thrush. Corvus graculus ( Chough). This species, which is the Cornish crow, the red-legged crow, and various other names, is an inhabitant of peculiar localities, but these localities are situated in many latitudes, and they are sometimes on the sea-coast, and sometimes inland. In all places, however, it appears to be a rock-bird, though not an inhabitant of all rocks indiscriminately, or even of all rocks which ap- pear to be in themselves of nearly the same character. In Britain the chough is found only on, or very near, the coast, and on those coasts only which are washed by the Atlantic and the Channel, and not upon these, if there are not rocks or lofty ruins to serve it for nesting-places. Dover and Cornwall, some parts of Wales, and a few spots on the west coast of Scotland and the Hebrides, are the British localities of the chough. It occurs as far to the north as Norway, and in the rocky mountains of central and southern Europe, in the Alps, the Pyrenees, &c. It is also found, at least at some seasons of the year, in places where there are few or no rocks, being par- ticularly abundant along the banks of the Nile in Egypt, when the inundations begin to subside, and the supply of reptile food becomes abundant ; but it does not breed on the banks of that river. The chough is black, with a tinge of violet ; and the bill and legs are red. The irides are hazel. The bill is differently shaped from that of any of the previously mentioned species of the genus, being longer in proportion, more slender, and bent for nearly the whole length, though only slightly. It is also much weaker, being brittle, and therefore not adapted for the hard labour to which the bills of some of the others are subjected. Of course it is used for different purposes, and the form and texture of the bill, together with the character of the haunts in which it is chiefly found, may help to guide us to the particular nature of its food, and consequently to the part which it performs in the economy of nature. The character of the feet is also of some importance ; they are very stout, or at least clean made for the size of the bird, and the claws are crooked and sharp, partaking a little of the prehensile character. Chough. Thus the bill of the enough is not adapted for digging into the ground, or for pushing and breaking hard substances, like the bills of most, others of the genus, nor are its feet adapted lor scraping ; it must therefore be a surface feeder, and its food animal or soft vegetable matter, or both. There are many small animals on the bank of the river which has been inundated, for the mud in such places, if the C O R V U S. 151 climate or even the weather for the time is hot, becomes absolutely alive ; and there are many similar creatures on the ocean strand, where the ebbing and flowing of the tide occasions something like an inundation, and its departure twice every day. Besides the animal food which it finds in those places, the chough is said to be very fond of those wild berries which are gene- rally abundant in the humid or marshy parts of the uplands, and these furnish it with at least a seasonal supply. Scopoli mentions that choughs feed much upon juniper berries, which, as they take a long time in growing, and are in several successions upon the bushes at the same time, continue ripening for a longer period, and are ripe more in the dry season than the annual crops ; and they are followed by the vacciniums and other berries of swifter growth and shorter harvest. In this the chough follows the same practice as the crows in the mountainous parts of our own country, which may be seen in the mountain marshes and other places which abound with berries after the nesting is all over, and there is little for them to plunder in the more dry and heathy parts of the moors. Choughs take a good deal of care in the construc- tion of their nests. These are usually formed in the crannies of the rock, about midway up the cliff, so as to be out of the reach of danger both from below and from above. There are a good many materials used, sticks to form the frame-work, and then a copious lining of wool, hair, or other soft matters, as may happen to be within the reach of the birds. The eggs are usually about four or five in number, rather larger than those of the jackdaw, of a dull white colour, with spots of ash colour and pale brown, which are most abundant at the larger end. Choughs seldom come abroad in stormy weather, but they are much on the wing when it is fine, flying high to and from their feeding grounds, and often uttering their cries, which are more shrill and wailing than those of jackdaws. They are very easily tamed, and get familiar and even attached to those with whose appearance they are familiar ; but they are not fond of strangers. The difference of their notes to those they know and those they do not are worthy of attention to their acquaintances. Their tones of address are soft and even coaxing ; but they utter a very harsh alarm note when any one whom they do not know approaches them. As is the case with all the race, they are very apt to steal and secrete pieces of money and other shining substances ; and in cot- tages, where sticks are burnt, they are apt sometimes to seize little pieces which are on fire at one end, and fly about with them in a way not altogether safe. CorvuA cart/ocatactes(t\ie SpottedCroworNutcracker.) This species is not uncommon on the continent of Europe, and it generally appears there in flocks ; but in Britain it occurs only in straggling specimens, and that very rarely. It is a very handsome bird, about the size of u magpie, or about thirteen inches long, and a foot and a half in the stretch of the wings. The general colour of the body is dusky brown, all marked over with triangular white spots. The crown of the head, the wings, and the tail, are blackish, the latter marked with white at the tip, and the middle feathers with the ends of their webs ragged and in- complete. There are some points of resemblance between the nutcracker and both the magpie and the jay; but the bill is of a different shape, the mandibles Icing straighter, blunter at the point, and of unequal length- Its attachment to localities is also different. It comes not near houses, like the magpie, neither does it d-vell in thick woods and copses on the rich grounds. It is more of a mountaineer, seeking the forests upon the elevated slopes, nestling in holes, and finding the chief part of its food in the kernels of trees, nuts, acorns, beech mast, the seeds of the coniferae, and other vegetable substances, which, in consequence of the hardness of their envelopes, remain on the ground as a store for nearly the whole season. The hardest of these it can readily break, and it is for this reason that it is called the nutcracker. From the retired nature of its habits in keeping to the wild woods at that season when the knowledge of it would be most interesting, very little is known of the domestic eco- nomy of the nutcracker ; and all that is known in Britain, save the mere appearance and colour of the bird, judged of from a casual straggler or a museum specimen, is at second hand. It is alleged by Klein, and some other of the continental describers, that there are two varieties, or even species, in the Alpine forests of central Europe — one with the bill strong and angular, and the tongue long, and forked ; and another with the bill rounder and weaker, and the tongue also divided at the tip, but much shorter than that of the former. It is further said that the one with the angular bill and the long tongue fairly breaks the shells of the nuts, while the other merely pierces them and extracts the kernel through the opening. Their nests are in the holes of trees ; and when they do not meet with these to suit their purposes, they are said to make them, or at all events to work them to the desired shape ; but, as we have already noticed, their habits are imperfectly known. The eggs are said to be about five or six in number, of a greyish fawn colour, and marked with spots of clear brown. The nutcracker is not understood to have so much cunning, or to be so much of a thief, as the magpie or the jay, though it is described as still retaining the omnivorous character, and sometimes varying its food by making a meal of another bird, the skull of which it very quickly hammers te pieces with its powerful bill. Adult birds of this species are said not to be tameable, as they obstinately refuse to take food ; but young ones can be tamed with nearly the same facility as others of the genus. In confinement they are said to be given to hoard and pilfer like the rest of the tribe, but whether they have this habit when in a state of nature is not known. On the continent this species is very generally distributed, being found not only on the wooded mountains of Europe, but in Siberia, as far as Kamts- chatka. Seasonally they leave the woods, and appear in considerable flocks, and in the flocking season they are often seen both in Germany and France. There are very many foreign species, either be- longing to this genus or very nearly allied to it, in almost every part of the world ; but we have not room for even a mere catalogue of the whole ; and their manners, in so far as they differ from those of the species already noticed, are so little known that they could not easily be made interesting to the general reader. We shall therefore close this very iinpei feet sketch by a mere notice of one or two of the most remarkable species. Cirri'its cristutus — Garrulus cristatus of Cuvier (the Blue Jay of America). This is a very beautiful spe- cies, resembling, in manv of its habits, the common 152 C O R V U S. jay of Europe. It is very generally distributed over at least the more temperate parts of North America ; and we cannot bring it so well before the reader as in the language of that prince of all ornithologists, Alexander Wilson. " This elegant bird," says this eloquent child and worshipper of wild nature, " which, as far as I can learn, is peculiar to North America, is distinguished as a sort of beau among the feathered tenants of our woods by the brilliancy of his dress ; and like most other coxcombs, makes himself still more conspicuous by his loquacity and the oddness of his tones and gestures. The jay measures eleven inches in length ; the head is ornamented with a crest of light blue or purple feathers, which he can elevate or depress at pleasure ; a narrow line of black runs along the frontlet, rising on each side higher than the eye, but not passing over it ; back and upper part of the neck a fine light purple, in which the blue predominates ; a collar of black, proceeding from the hind head, passes with a graceful curve down each side of the neck to the upper part of the breast, where it forms a crescent ; chin, cheeks, throat, and belly, white, the three former slightly tinged with blue ; greater wing- coverts, a rich blue ; exterior sides of the primaries, light blue, those of the secondaries a deep purple, except the three feathers next the body, which are of a splendid light blue ; all these, except the primaries, are beautifully barred with crescents of black, and tipt with white ; the interior sides of the wing-feathers are dusky black ; tail long and cuneiform, composed of twelve feathers of a glossy light blue, marked at half inches with transverse curves of black, each feather being tipt with white, except the two middle ones, which deepen into a dark purple at the extre- mities. Breast and sides under the wings a dirty white, faintly stained with purple ; inside of the mouth, the tongue, bill, legs, and claws, black ; iris of the eye hazel. " The blue jay is an almost universal inhabitant of the woods, frequenting the thickest settlements as well as the deepest recesses of the forest, where his squalling voice often alarms the deer, to the disap- pointment and mortification of the hunter ; one of whom informed me, he made it a point, in summer, to kill every jay he could meet with. In the charming season of spring, when every thicket pours forth har- mony, the part performed by the jay always catches the ear. He appears to be among his fellow musi- cians what the trumpeter is in a band, some of his notes having no distant resemblance to the tones of that instrument. These he has the faculty of changing through a great variety of modulations, according to the particular humour he happens to be in. When disposed for ridicule, there is scarce a bird whose peculiarities of song he cannot tune his notes to. When engaged in the blandishments of love, they resemble the soft.chatterings of a duck, and while he nestles among the thick branches of the cedar, are scarce heard at a few paces distance ; but he no sooner discovers your approach than he sets up a sudden and vehement outcry, flying- off, and screaming with all his might, as if he called the whole feathered tribes of the neighbourhood to witness some out- rageous usage he had received. When he hops undisturbed among the high branches of the oak and hickory, they become soft and musical ; and his call of the female a stranger would readily mistake for the repeated screakings of an ungreased wheel- barrow. All these he accompanies with various nods, jerks, and other gesticulations, for which the who e tribe of jays are so remarkable, that with some otaer peculiarities they might have very well justified the great Swedish naturalist in forming them into a separate genus by themselves. " The blue jay builds a large nest, frequently in the cedar, sometimes on an apple tree, lines it with dry fibrous roots, and lays five eggs of a dull olive, spotted with brown. The male is particularly care- ful of not being heard near the place, making his visits as silently and secretly as possible. His favourite food is chestnuts, acorns, and Indian corn. He occasionally feeds on bugs, caterpillars, and sometimes pays a plundering visit to the orchard, cherry rows and potato patch ; and has been known in times of scarcity to venture into the barn, through openings between the weather boards. In these cases he is extremely active and silent, and, if surprised in the fact, make his escape with precipitation, but without noise, as if conscious of his criminality. "Of all birds he is the most bitter enemy to the owl. No sooner has he discovered the retreat of one of these, than he summons the whole feathered fraternity to his assistance, who surround the glimmering solitaire and attack him from all sides, raising such a shout as may be heard in a still day more than half a mile off. When in my hunting excursions, I have passed near this scene ot tumult, I have imagined to myself that I heard the insulting party venting their respective charges with all the virulency of a Billingsgate mob ; the owl meanwhile returning every compliment with a broad goggling stare. The war becomes louder and louder, and the owl at length, forced to betake himself to flight, is followed by his whole train of persecutors, until driven beyond the boundaries of their jurisdiction. " But the blue jay himself is not guiltless of similar depredations with the owl, and becomes in his turn the very tyrant he detested, when he sneaks through the woods, as he frequently does, and among the thickets and hedge rows, plundering every nest he can find of its eggs, tearing up the callow young by piecemeal, and spreading alarm and sorrow around him. The cries of the distressed parents soon bring together a number of interested spectators (for birds in such circumstances seem truly to sympathise with each other), and he is sometimes attacked with such spirit as to be under the necessity of making a speedy retreat." Corvus Canadensis (the Canada jay) is by no means so showy a bird as the former. It is described as being " eleven inches long, and fifteen in the extent of the wings ; back, wings, and tail, a dull leaden grey, the latter long, cuneiform, and tipt with dirty white ; interior vanes of the wings brown, and also partly tipt with white ; plumage of the head low and pro- minent ; the forehead and feathers covering the nostrils, as well as the whole lower parts, a dirty brownish white, which also passes round the bottom of the neck like a collar ; part of the crown, and hind head black ; bill and legs, also black ; eye dark hazel. The whole plumage on the back is long, loose, unwebbed, and in great abundance, as if to protect it from the rigours of the regions it inhabits. "A gentleman of observation, who resided for many years near the North River, not far from Hudson, in the state of New York, informs me that he has parti- cularly observed this bird to arrive there at the CORYPH.ENA. 153 commencement of cold weather; he has often re- marked its solitary habits; it seemed to seek the most unfrequented shaded retreats, keeping almost con- stantly on the ground, yet would sometimes, towards the evening, mount to the top of a tree, and repeat its notes (which a little resemble those of the baltimore,) for a quarter of a hour together ; and this it generally did immediately before snow or falling weather." Corvus ossifragus (the fishing crow). This is another North American species, which is worthy of notice on account of the peculiarity of its habits. They are wholly aquatic birds ; and are scavengers upon the numerous and productive waters of that part of the world, especially of those which are near the coast. They are birds of powerful wing for their size, and furnished with large and crooked claws. They hover along over the surface of the waters, and are ever and anon twitching down to seize in their claws any dead fish or other garbage that may be floating. They are most abundant in the southern part of the States, where the waters are more pro- ductive ; they are understood to perch and nestle in high trees near the waters ; and they are very com- mon about fishing villages and fishing stations. It does not. appear that they depend much on the land for their food, or in any way injure its cultivated produce. The following is the description : — they are sixteen inches in length, and thirty-three in the stretch of the wings ; black all over, with reflections of steel blue and purple ; the chin is bare of feathers around the base of the lower mandible. Upper mandible notched near the tip, the edges of each turned in- wards about the middle ; eye very small, placed near the corner of the mouth, and of a dark hazel colour ; recumbent hair or bristles, large and long ; ear feathers, prominent ; first primary little more than half the length, fourth the longest ; wings when shul h within two inches of the tip of the tail ; tai rounded and seven inches long from its insertion thighs, very long; legs, stout; claws sharp, long am hooked, hind one the largest, all jot black. Male anc female much alike. besides those which \vc have noticed there are many species or varieties in different parts of the world ; but the manners of them all arc very similar ; and it is exceedingly probable the climata varieties of those which are common with us, have been described as different species. CORYPH^ENA Coryphene; the dolphin of the ancients. A genus of spinotis-finned fishes, with ab dominal fins, situated immediately under the pectorals and thus referrible to the thoracic fishes of the Lin mean system ; but included in the mackerel family (Soofnber6idce) in Cuvier's structural arrangement They are numerous, and vary much in size, in colour and in several other of their external appearances but their generic characters are well made out, am there is a good deal of similarity in the habits of then all. The leading characters are : — The body corn pressed, elongated, and covered with very small scales the head short, and truncated on the upper part ; th gill-lids smooth, and with seven rays in the gill-flap the dorsal fin beginning immediately behind the head and ranging the whole length of the back, its ray of nearly the same flexibility throughout the whoL length, but. those of the anterior part have no articu l;ti'n>:i. All the members of this genus arc pelagi fishes, enjoying free range of the wide sea, in the dee] water rather than over the banks, remaining an eeding near the surface. They arc generally splcn- iid in their appearance ; and in point of colour, at east, they are among the most beautiful inhabitants the deep. The brilliancy of their colours vanishes n death ; so that it is impossible to form any idea of hem from museum specimens, how carefully soever hese may be prepared and preserved. This holds, indeed, with regard to all the more splendid fishes; and, as the tints and lustres which they display, have a transparency about them, which does lot belong to even the finest colours of land animals, so they have an evanescence, which renders it impos- sible to form any idea of them, unless when they are seen alive and in health. Those of this species, in particular, pass through a number of beautiful rainbow ;ints, while they are in the agonies of death ; and this was one of the reasons why the luxurious Romans were so very fond of having coryphenes at their sumptuous entertainments ; they did not, however, serve up these fishes, at least in the first instance, in the style in which fishes are served up at the tables of modern epicures. The}' brought them to table alive, so that the company might enjoy the luxury of seeing them die. After this they were withdrawn, cooked, and brought back again as an article of food. Coryphenes are most abundant in the tropical seas, though some of them are found in the Mediterranean, but there are none in the polar seas, or, indeed, in very high latitudes, though it is probable that they extend farther into the southern hemisphere than the northern. They are remarkable for energy of life ; and the radiant and finely varying tints which they display are living lustres, and add greatly to the beauty of the wide soas. When they are coursing over the sea in shoals, which they generally do, though the shoal is never of wearisome extent, and the bright sun of the tropi- cal sky is beating on them through a thin and con- tinuallv varying stratum of water, and when they themselves are shooting along with the rapidity of flashes of lightning, they form an exhibition, than which there are few more beautiful in nature. Indeed, gorgeous as are many of the flowers in tropical coun- tries, and gay as are many of the birds, their colours do not refract, and decompose, and reflect the light and return it in such an endless variety of tints, all liquid, as if they were molten in the element in which the creatures live, as is done by the fishes. The sublimity of the wide sea, and the steady trade wind soon palls upon the sense ; and, as there is little to be done on board ship in such places, and the heat is relaxing to Europeans, a passage there would be a very dreary matter, were it not for the sporting of the fishes, and of the long-winged birds, which rival the coryphenes in seeking their prey over the extensive ocean. In such situations a shoal of coryphenes presents a rich treat to the spectator ; nor is it by any means a passing glory, like a meteor in the sky, to be viewed only for a moment, and talked of afterwards as a thing of memory. They keep company with the ship for days, and even for weeks, ranging along for hundreds of miles ; and, though the rate of sailing is consider- able, it is in fine weather nothing at all to the speed of swimming in the coryphenes. They play round and round the ship, now shooting a-head, now getting astern, on the starboard at one time, and on the lar- board at another. In every position of themselves and the light they are brilliant ; but in no two posi- 154 CORYPHvENA. tions of eitner one or the other are they exactly the same. At one time they are gold, at a second eme- rald, at a third sapphire, at a fourth amethyst ; then they are carbuncle and ruby, and so on through every imaginable colour, named or unnamed ; and in all they have that radiance which we have mentioned as.among living creatures, belonging only to the inhabitants of the deep. Nor are these uniform changes of the whole shoal ; for as they do not all maintain the same posture, the same attitude, or the same depth in the water, the whole of this variety is given to the eye at once, so that it seems as if every varied beam into which the utmost radiance of a tropical sun can be divided were in continual play over them. Then there is another part of the accompaniment which, though it has not all the innocence of this beautiful display of varied colours, is not without in- terest in its own way. These fishes cannot perform their rapid motions, so much exposed to the action of the sun, without considerable waste of their system ; for it is a law of nature, that powerful action, of what- ever kind it may be, requires support and renewal of substance in proportion to its energy. Hence the coryphenes are exceedingly voracious, and it is their voracity which makes them follow the ship with such persevering assiduity. Not, of course, that they ex- pect to eat the ship ; though they are not very par- ticular as to the quality of what they swallow ; but there is always some sort of fat thrown overboard, and this forms the chief attraction which ships have for those fishes that follow them. It is singular how such an opinion of the acuteness of smell in fishes could have originated, as the parties have evidence of its falsehood constantly before their eyes. Every one knows that there is nothing pecu- liarly tempting to the olfactory nerves of a trout, in an artificial fly or an artificial minnow, and yet, when skilfully managed, these are as successful as real baits. The very fishes in question too, and indeed the whole mackerel family, seem to hesitate so short a time about smells, that a bit of scarlet rag, tin plate, bright shell or brass button, is taken by them just as readily as any other bait. Even in some of the soft-finned fishes wh'ich seem to have the olfactory nerves a little more developed, there appears to be an equal incapacity of distinguishing between what is food and what is not. When the workmen were occupied in erecting the light-house on the Bell- rock, they found the water over some parts of that rock so thick of whitings that they literally concealed the bottom for an extent of many yards"; and they were as voracious as they were numerous, and as heedless as either; for the men had only to tie a crooked brass pin to the end of a bit of string, and so draw up whitings in any quantity they chose. But to return to the coryphenes. All that these fishes can glean from the refuse thrown overboard from a ship would, of course, not support the millionth part of their number ; and consequently they must be provided with other food, otherwise they could not exist in nature. One staple article with them is the flying fishes (see EXOCETUS), which they pursue with nearly the same assiduity as the porpoise pursues salmon, but with much greater success and more splendid effect ; and, if any comparison could be instituted between land predatory animals and sea ones, one might say that the porpoise more resembles a bear on the pursuit, and the coryphene more a leo- pard ; for the porpoise is ugly in its colour, and lum- bering in its motions, while the coryphene is swift and beautiful. In both cases the prey, when the case becomes one of extremity, attempts to escape by leap- ing out of the water ; and, though the salmon falls instantly, and, generally speaking, into the mouth of its pursuer, while the flying-fish can keep in the air a little, as if it were supported on wings, yet its flight is short, and it not only increases the chance of being captured bv the coryphene, but also subjects itself to as great danger from another enemy, the albatross or some other pelagic bird. Thus, it appears, that the flying-fish has rather an under share of piscine enjoy- ment. It is usually said that fishes, exempted from the burden of themselves in the air, and also from the vicissitudes of that element, have really nothing to do but enjoy one continual feast by eating one an- other ; for which feast their amazing fertility affords a plentiful supply, in which all that man takes for his use is not missed. It is not supposed that the flesh of any species of corypheno is poisonous; but, from the fleetness of their motions it is hard, dry, and tasteless, yet that of many of the species is eaten. Cuvier divides the genus into several sub-genera, which we shall barely notice : — CORYPHENES, properly so called. These have tlio body compressed, the head very much raised, the pro- file arched, the outline descending very rapidly to the muzzle, the eyes situated very low down, teeth on the palate as well as the jaws, and they are of larger size than the others. Their dorsal fin, which is very hand- some, extends all the way from the nape to the tail ; the caudal fin is forked in some, straight in others, and in others again rounded or pointed. Coryph&ne hippuris — common coryphene. This is the largest species of the whole, attaining the length of at least five feet. It occurs in the Mediterranean, and also in the oceans near the tropics. Its dorsal fin is long, with its edge nearly parallel to the line of the body, and the fork in the tail is deep. The back is bright sea-green, mottled with small orange spots ; the belly is silvery ; the lateral line yellow, the dorsal fin bright sky-blue, with gold coloured rays ; the caudal fin greenish ; and all the remaining fins yellow. This species is the dolphin of the ancient fables. Three or more species have been enumerated by systematic writers, as belonging to the forked-tail subdivision of true coryphenes ; but it is exceedingly difficult to determine what is a species, and what is not, in fishes which are so active and so highly co- loured ; and, as the difference between the one and the other does not appear to relate much either to structure or to manners, it is comparatively of little importance. The statement usually made is, that those species which occur to the south-eastward of Asia are brighter in colours, smaller in size, and even more rapid in their motions, than those which occur in the Mediterranean and the Atlantic ; but their mo- tions are so flat, and they are so seldom seen, that we cannot come to any positive conclusions respecting them. We may, however, just mention one or two of the most beautiful of this species. Coryphcena aurata (the golden coryphene). This species is found in the Indian seas, is very rare, and has not been met with of so large a size as the cory- phene of the Mediterranean. Its dorsal fin is shorter, and all blue without the gold-coloured rays. The tail is deeply forked, and all over of the colour of polished gold. The body consists of an endless variety of brilliant colours, which it is not possible to describe. C O T I N G A. 1*5 Coryphana Boryi. Tliis species is described as inhabiting- the intertropical part of the Atlantic, and as differing in its shape from both the former, it being enlarged at the middle, so as to approach the form of the rlat fishes. It has not been found more than two feet in length ; and it is reported as affording more savoury food than the others. It is described as being the most beautiful of all the h'shes. The dorsal fin is high at the fore part, and gradually diminishes to the tail. It is of the most brilliant ultra-marine blue, marked with bright lines of rich indigo blue. The upper part of the head is a rich brown, passing through very fine tints of omerald green on the back into golden yellow on the sides and tail. The margin of the yellow is delicately marked with greyish ; and the belly is silvery. All the fins, except the caudal and the dorsal are yellow. The caudal is deeply divided, or rather it consists of two separate fins attached to the extremity of the animal. CoryphcEiia chrysurus — golden-tailed coryphene. This species is found in the south sea. Its body is very elongated. Its tail is of a remarkably brilliant gold colour, the back azure, the dorsal fin blue, spot- ted with yellow, the under part silvery, and all along the upper part marked with lenticular spots of deep blue, very numerous, and placed irregularly. Coryplicpna lutea — yellow coryphene. This species is described as being an inhabitant of the Indian seas, chiefly yellow on the upper part, and silvery on the under. Both this and the species immediately pre- ceding, are described as being most assiduous in cap- turing the different species of flying fishes. The species with the tails straight or rounded, or lancet- shaped, have chiefly been observed in the eastern yens ; and it is probable that they ought not to be in- cluded in this sub-genus, and some of them not in this genus at all. CENTKOLOPUS. This division of the genus have two spinous prominences in front of the dorsal fin, but the spines are so short that they can be felt only by pressing the finger pretty strongly against the skin. Their bodies are compressed, their scales small, their head longer than that of the true coryphenes, but ob- tuse at the muzzle. One species of this division has acquired some celebrity, at least it possessed some in ancient times on account of its attendance upon vessels. This is, Coryph&na pumpilux, so called as it forms part of the cortege or train of the ship. It is about a foot in length, diminishing in thickness towards the tail, feels greasy to the touch ; its back is marked with yellow bands, and there are golden yellow stripes above the eyes resembling eyebrows. This species is found both in the Mediterranean and the Atlantic. LEPTOPODES. This division, like the former, has dorsal prominences barely discoverable by the finger ; but it differs in having the dorsal and anal fins run- ning into each other, so as to form a pointed tail. — There is only one known species (Leptopodes Ater), which is a little fish, feeble, and timid. It is found in the Mediterranean, in the deep water, during the greater part of the year, but approaches the shore about the month of August for the purpose of spawn- ing. It is about six inches in length ; the general colour is deep black, with violet reflections. Its muz- zle is rounded, its eyes small, with golden irides. In the spawning season it might be taken in any quan- tity, but its flesh is soft and insipid, and good for nothing. There are many important particulars to be learned from the careful study of those pelagic fishes which range far and wide over the sea ; and no species of them are calculated to afford us more information in this respect than the mackerel family ; because they live more exposed than almost any other fishes, and, therefore, they serve better as indexes to the general economy of nature in the sea. But in proportion as their manners and the influence of varying seasons upon them are important, they are difficult to be studied ; because the sea is a wide surface, of which man can see but a small part at once, and we do not meet with the same inhabitants, or even the same water, when we twice visit the same spot. CoSSUS. A genus of lepidopterous insects, belonging to the family HEFIATIDA:, which see. COT1NGA — Ampelis. A genus of American birds, belonging to the fly-catching tribe of the dentirostral division of Cuvier's great order Passeres, and ranged between the fly-catchers properly so called and the bee-eaters. These birds were ranged by the elder ornithologists, along with many others, in a very extensive genus, but they have been since subdivided. The cotingas, properly so called, all inhabit the rich and humid forests of America. They are conspicuous for the rich colours of their plumage, in which purple and blue are the prevailing tints. The characters are : (,he bill of mean length, a little depressed, higher than wide, three cornered at its base, flattened at its point, moderately hard ; upper mandible convex, with a ridge on the culmen,. and notched towards the point, which is curved ; the inferior mandible a little flattened on the under side ; nostrils at the sides of the base, round, half closed with membrane and by some silky feathers ; feet of mean size, three toes to the front, one behind ; the two outside, in front, united to the second ; and the hind toe the same length as the outer one ; wings rather short, the first quill shorter than the second, which is the longest in the wing. As restricted by Cuvier, the genus Cotinga is a very peculiar one, and does not contain a very great number of species. The birds which compose it are all of a wild and retiring character, shy and silent, having nothing in their conduct or their sounds at all corresponding to the brightness of their covering. They are found only at those parts of America which have a strictly tropical climate, and even in these, they are confined to moist and shady situations which abound with insects, though they are also understood to live, in part, upon soft and sugary fruits. They are not, however, so destructive to plantations as many other birds that have the same mode of feeding ; but though they are retiring, and also confined within geographical limits, they are not absolutely stationary ; yet, the only object of their little voyage is, to arrive in certain places at the epoch in which the fruits they subsist on are mature. In Guiana, the spots in which they most delight, in those seasons when they are seen near habitations, are humid places. It is an error to suppose that they are destructive to the rice grounds. From the peculiar conformation and absence of solidity in their bill, it is impossible that they can be granivorous birds. According to Sonnini, the inhabitants do not eat their flesh, and if the stuffed specimens often arrive in Europe in a bad state, this is not the reason ; it is rather, because the feathers not being very adherent, the tender skin requires a degree of care in its preparation, which is not always 156 C O T T U S. bestowed upon it in America. The size of the cotinga varies from that of the raven to that of the song thrush. The colours of the females are, in general, much less rich than those of the males ; their plumage is, indeed, frequently dull and dusky. The habits of these birds, and the facts concerning their reproduction, are very imperfectly known ; many species, however, are known to make their nests on the loftiest trees, and lay four or five eggs. As the same parts of the forests in which these birds nestle, are inhabited by climbing quadrupeds, which are much disposed to plunder both eggs and young, the birds take the precaution of building at heights, and under circumstances of concealment, which make their broods pretty safe, not only from quadruped enemies, but from nest-plundering birds, of which there are many species in the luxurious forests of tropical America. Thus, the cotingas, in their quiet way, contrive to get on as well in their domestic economy as the most noisy tenants of the forest. Their general history is a short one : they live in the very richest places of the world, feed well, wear handsome clothing, dwell in secure habitations, and take as little fatigue as they possibly can. We shall just mention one or two of the species. Blue Cotinga. — Plumage bright azure, with the exception of the head, neck, and breast, which are rich purple ; the quills and coverts, and also the bill and feel, are black. These are the colours of the male bird , and the length is about eight inches and a half. The female is of a blackish brown with purple reflections on the under part, and each feather slightly bordered with white. Head and under tail- covert red. The young, while in their nest, in plumage resemble the female. This species is found in Guiana. Brazil Cotinga or Blue Riband. — This is a very beautiful species, rather smaller than the former. Its upper part is exceedingly bright azure blue ; the under part rich violet purple, with a band of black crossing the breast, the quills, and the coverts. The bill and feet are black. The young have the under part marked with small flame-coloured spots. There are three or four species more, which appear to be tolerably well defined and established, and there are some others which are doubtful ; but, as we have already sard, there is not much of interest in the manners of the birds, nor would there be more to the general reader in merely running over changes or markings of colour, however beautiful. COTTON, is the name of the plant, as well as of the filaceous substance produced by the Gossypium, Herbarium, Vitifolium, &c., of botanists. Linnsean class and order, Monadetphia Polyandria, and natural order, Maloacea:. Generic character : involucrum large, three-cleft, persisting, segments heart-shaped , calyx goblet-shaped, five-toothed ; petals inversely heart-shaped ; stamens united in a cylinder ; anthers kidney-shaped ; style columnar ; stigmas three or five ; seed-vessel three-celled and three-valved ; seeds enveloped in wool. It is almost unnecessary to ob- sewe, that this is one of the most useful plants known, and not only to the warmer parts of Asia, where it is cultivated, but to every other part of the civilised world, whether favourable to its culture or not. As an article of commerce and manufacture, it rivals the fleeces of the northern latitudes, and perhaps employs as much, or more capital, than any other branch of trade whatever. For further particulars, see MAL- VACEAE. COTTUS (Bull-head). A genus of spinous-finned fishes, belonging to Cuvier's division of Jouet cuirassees, or fishes with hard plates on the cheeks, and which he ranks immediately after the perch family. The relations of the family will be pointed out shortly in the article HARD CHEEKS, and more at length in the general article FISH, so that we shall only, in this article, have to notice the generic characters, adding some short notice of the species, particularly of such as are British. The most general description which can be given of this genus of fish is, — that they are all very small and very ugly, and, at the same time, of little or no use to man ; but, from their very general distribution, they must answer some important purpose in the eco- nomy of nature, and there is little doubt that they are also of much indirect importance to the human race, in affording food to larger and more valuable fishes. The generic characters are : the head large and depressed, furnished with hard plates on the cheeks, which are variously armed with spines and tubercles : two dorsal fins ; teeth in the advanced part of the vomer, but none in the palatal bones ; six rays in the gills, and three or four only in the ventral fins. They have no air bladder. The head is disproportionately large, flattened, and has the eyes turned upward, which gives them an unhandsome appearance ; their colours also are very dull, and their skin is, in general, covered with a mucous secretion, so that they slide through the fingers of those who offer to catch them. They are found both in the fresh waters and in the sea, but the greater number are inhabitants of the fresh waters, and these have the head always smooth and only one spine on the gill-lid. They are, though small, lively and active fishes, lurking under stones and in small holes of the banks and bottoms, from which they issue with great rapidity, and seize fry-worms, the larvae of aquatic insects ; but as some of them inhabit fresh water and others salt, and as the ones that have these different haunts have also necessarily different manners, it will be desirable to treat each species by itself. Of the enumerated species, at least five are natives of Britain ; and as, though they are not of much value in an economical point of view, they are of some curiosity as subjects of natural history, we shall give some notice of each of them. Coitus gobio, the river bull-head, miller's thumb, tommy logge, and various other names. This species seldom exceeds four inches or four and a half in length ; its head, though flattened, is broad, but its body is very slender. It is pretty generally distri- buted over Europe, being Tound in most of the small streams of fresh water from Italy to Russia ; but it is found only in gravelly places, or, at least, where the water is not impregnated with peat, and, for this reason, it is not general in Scotland or in Ireland, except in the north-east part of the country, where there are no peat bogs. Its flattened head and hard cheeks enable it to poke itself under stones ; and thus, as its motions. are veryquick.it is not seen without some difficulty. Those who are curious in tracing the origin of popular names, suppose it is called the bull-head in consequence of the size of its head, though it probably receives this appellation as much from its wrinkled front. " The miller's thumb" has given rise to various other speculations. Some have said that the thumb of a miller derives a parti- cular shape, resembling that of the head of this fish, C O T T U S. 157 from his thumbing the meal to try if it is properly ground. But it is prohable that the mere i'act of the fish being found preity generally in mill-streams may have given origin to the name ; tor the head of the fish is more like the thumb of a cobbler than that of a miller. As this species is greasy to the feel and insipid to the taste, and as it contains little flesh, good or bad, it is not eaten in this country; but it is said to be eaten in Italy ; and that, in some parts of the north of Europe, it is hung up, exactly balanced, in order that by the direction of its head it may tell how the wind sets, which, of course, it does not do unless exposed to the wind. The particular characters of this species are : the mouth wide, the jaws of nearly equal length, with numerous pointed teeth in both jaws, and also on the anterior part of the vomer ; the head spinous ; pupils of the eyes dark blue, irides yellow; gills ending in a flattened point ; a membrane between the two dorsal fins ; rays of all the fins spotted ; upper part blackish brown ; sides lighter, spotted with black, under part white. This species deposits its spawn in summer. Coitus bubalis (father-lasher, long spined-cottus). This is a very formidable looking fish, and from its shape, its numerous spines, and a variety of other peculiarities in its appearance, it is a fish of some interest. It belongs to the cold seas rather than to the warm ; and though it is rarely met with on the British shores of more than from six to nine inches in length, it grows much larger in the extreme north, and the natives of Greenland are said to make a sort of soup of it, similar to that which is made of the haddock in Scotland. In ordinary cases the father- lasher expires the moment it is taken out of salt water and put into fresh, but by gradually passing through the brackish water it is said to be able to ascend the estuaries for the purpose of depositing its spawn, which it does about the month of January. It is by no means uncommon on the British shores, and is frequently left, at low water, in small pools among the rocks, and when it is attempted to be caught by the hand it puts on rather a formidable appearance, by distending its gill-covers, erecting the spines, and making motions as if it were disposed to strike right and left at any one who might attempt to seize it. We know not what may be the cause, but there are many parts of the east coast of Scotland where this fish is more fequently found dead on the beach than any other species; and as we have generally met with its body upon gravelly beaches where the current runs strong, it may be that it gets entangled iimong the stones and stranded, or that the want of an air-bladder may prevent it from managing itself well in turbulent water. Notwithstanding the frequency of the dead body of this fish on the places of the coast that have been alluded to, it is by no means a delicate fish, but on the other hand remarkably tenacious of life. It is well observed by Mr. Yarrell, in his work on British fishes, now in course of publication, that the large- ness of the gill-openings of fishes, cannot be the only cause why they die soon when taken out of the water. All fishes which have the gill-lid armed with erectible spines, have more power over it than those which possess no such armature ; and we may naturally conclude, that they are able to move these with less derangement to the fibres of the gills when 'these are not supported in water. The head of the father-lasner has some resem- blance to that of a lurking predatory quadruped, with its ears laid backwards against its neck, and prowling for prey. The eyes are very near to each other, and the sight directed vertically, their colour, black pupils with yellow irides, gives them a little the air of those of a wild beast ; and this is further heightened by the elevation and straightness of the frontal ridges. These ridges are continued quite to the nape, where they end in two spines ; there are also four spines upon the pre-operculum, of which the upper one is of considerable length ; one on the scapula, and a clavi- cular one on each side, and two on the nose. The colour on the upper part is dark brown, mottled with red brown, the under part is white. There has been some confusion between this and another marine species, although in appearance there is a good deal of difference between them. This other species is — Coitus scorpius (the sea scorpion, or short-spined cottus). This is also an inhabitant of seas far to the north, and understood to grow to a larger size in cold latitudes than in those which are more temperate ; and though it is not very likely, still it is possible that it may seek the more southerly haunts for the purpose of spawning. With us it is about the same size as the other, and it is found abundantly in many parts of the shore. In its general appearance it holds a sort of middle place between the river bull-head and the father-lasher. The head is large, more elevated than that of the bull-head, with a prominent ridge between the eyes and the snout, and a spine on each side of it. There are no spines on the nape, but there are three short ones on the pre-operculum, and two on the operculum itself. The colour is nearly the same as that of the former species, but the shape of the fins is different, and the ventral fins are attached, posteriorly, to the belly of the fish by a membrane. It is understood that this species spawns much later in the year than the father-lasher, which latter species spawns in January. Cottus quadricornus. This is also a northern species* being much more frequent on the northern shores of Europe than in the temperate countries, though it is by no means rare on some parts of the east coast of Britain ; and it is understood that this is about the last fish that is met with in the extreme north. There are four horned tubercles on the upper part of the head, from which it gets the name of four horned. It has three spines on the pre-operculum, and one only on the operculum. The body of it is more elongated than that of the other species ; the head is brown, with some red on the gill-covers, the sides yellowish, and the belly white ; the fins are finely clouded and mottled. It grows to be a little larger than any of the others, at least it grows longer ; but it is seldom used unless as a bait for other fish. This species comes much more rarely on the British shores, so as to be taken in the pools at low water, than any of the former; but it is not unfre- quently met with by the fishers for sprats. All the marine species of this genus are under- stood to be voracious, and to feed chiefly upon the fry of other fish, and upon small crustaceous animals, which last they catch in great numbers among the sea weed. They cannot be considered as giving any very striking character to the places which they inhabit, inasmuch as they arc but of diminutive size, do not crowd in numerous shoals, and are of little value. They have, however, a distinct geographical 168 COW-UUNTING. locality, and therefore, they -must, in so far, form an index to the general economy of nature in that locality, if we could but once become acquainted with their manners. The allied tribes which used to be included in the same genus, but are now separated from it, differ in some of their characters ; but it may not be amiss here to mention one of them which is still popularly, at least, considered as a bull-head. This is, Aspedorus Europceus, the armed bull-head or pogge, the characters of which are : the body eight cornered, covered with scaly plates, and tapering toward the tail. The head thicker than the body, snout with red coloured spines, and teeth in both jaws, but none on the vomer. Two distinct dorsal fins, but smaller than those of the former species. This is a northerly fish also ; but in summer it is found in most of the sandy bays, near the mouths of rivers on the east coasts of Britain : it is small, not above six inches in length, but its flesh is described as being firmer and better than that of the true cotta. COW-BUNTING, or CATTLE-BIRD (Molo- thrus pecoris, Swainson). " There is one striking peculiarity in the works of the great Creator," observes Wilson, the historian of the birds of the United States, " which becomes more amazing the more we reflect on it, namely, that he has formed no species of animals so minute, or obscure, that are not invested with certain powers and peculiarities, both of outward con- formation and internal faculties, exactly suited to their pursuits, sufficient to distinguish them from all others; and forming for them a character, solely and exclusively their own. This is particularly so among the feathered race. If there be any case where these •characteristic features are not evident, it is owing to •our want of observation ; to our little intercourse with .that particular tribe ; or to that contempt for inferior Animals, and all their habitudes, vvhich is but too general, and which bespeaks a morose, unfeeling, and unreflecting mind. These peculiarities are often sur- prising, always instructive when understood, and, (as in the subject of the present article,) at least amusing, and worthy of being farther investigated." "The American cattle-bird, the subject of the present memoir, is a small bird, about the size of the European sky-lark, and belongs to the natural family Sturnidte, or starling tribe ; forming one of the many connecting links between that family and the Fringillidce, or finches. It is closely allied to the troopials (Aglaius}, or the genus to which the common red-winged black- bird (as it is locally called) of North America belongs ; but is even more finch-like, or rather bunting-like, in its form, and so very peculiar and remarkable in its habits and history, that it cannot exactly be classed in the same division with any other known species. The form of the bill is very nearly that of the true bunting (Emberiza), but straighter, and more starling- like in its outline ; and the general shape of the body is about the same as that of the troopials, only rather more finch-like ; its length is about seven inches, and extent of the wings eleven inches. The head and neck are of a very deep silky drab, and the upper part of the breast a dark changeable violet ; the rest of the bird black, with a considerable gloss of green when exposed to a good light. Tail, slightly forked ; legs and claws glossy black, strong and muscular ; iris of the eye dark hazel. The female is, all over, of a brown colour, somewhat paler underneath, and the young male birds are, at first, altogether brown, and, | for a month or more, are naked of feathers round th« eye and mouth ; the breast is also spotted like that of a thrush, with light drab and darker streaks. IB about two months after they leave the nest, the black commences at the shoulders of the wings, and gradually increases along each side as the young feathers come out, until the bird appears mottled on the back and breast with deep black and light drab. At three months the colours of the plumage are complete, and, except in moulting, are subject to no periodical change. The sexes also are alike in size, and do not exhibit, in this respect, the remarkable disparity which is observed in all the troopials. " The most remarkable trait in the character of this species is, the unaccountable practice it has of dropping its eggs into the nests of other birds, instead of building and hatching for itself, and thus entirely abandoning its progeny to the care of strangers. More than two thousand years ago, it was well known, in those countries where the bird inhabits, that the cuckoo of Europe (Cucu/us canurus'j" — See CUCKOO — " never built herself a nest, but dropt her eggs in the nests of other birds ; but, among the thousands of different species that spread over that and other parts of the globe, no other instance of the same uniform habit has been found to exist," (save, however, in one or two other species of L'HCHI'US,) " until discovered in the bird now before us. Of the reality of the former there is no doubt ; it is known to every school-boy in Britain ; of the truth of the latter I can, myself, speak with confidence, from personal observation, and from the testimony of gentlemen, unknown to each other, and residing in different and distant parts of the United States." These are the words of Wilson ; and, as those of an original observer are always far better than any abstract that can be made of them, we will here copy his description of the habits of this singular species at some length, intending also to give a rather detailed account of those of the European cuckoo ; the pecu- liarities of the one being found to throw not a little light upon those of the other. " The circumstances," he continues, " by which I became first acquainted with this peculiar habit of the bird are as follow : — ' I had, in numerous instances, found, in the nests of three or four particular species of birds, one egg much larger, and differently marked from those beside it ; I had remarked, that these odd-looking eggs were all of the same colour, and marked nearly in the same manner, in whatever nest they lay, though frequently the eggs beside them were of a quite different tint ; and I had also been told, in a vague way, that the cow-bird laid in other birds' nests. At length I detectfd the female of this very bird in the nest of the red-eyed fly-catcher, which nest is very small, and very singularly constructed ;" (a neat pensile nest, hung by the two upper edges, and very firm and durable). " Suspecting her purpose, I cautiously withdrew without disturbing her, and had the satisfaction to find, on rny return, that the egg which she had just dropt, corresponded as nearly as eggs of the same species usually do, in its size, tint, and markings, to those formerly taken notice of. Since that time, I have found the young cow-bunting, in many instances, in the nests of one or other of these small birds. I have seen these last followed by the young cow-bird, calling out clamorously for food, and often engaged in feeding it ; and I have now. in a cage before me, a very fine one, which, six months CO W-B U N TI NG. 159 ;vtro, I took from the nest of the Maryland yellow tliroat, &c. * * * I claim, however, no merit for a discovery not originally my own, these singular habits having' long been known to people of observation resident in the country, whose informa- tion, in this case, has preceded that of all our school philosophers and closet naturalists, to whom the matter ha?, till now, been totally unknown. " About the twenty-fifth of March, or early in April, the cow-pen bird makes its first appearance in Pennsylvania from the South, sometimes in company with the red-winged blackbird," (or troopial, Aglains pheeniceus,) " more frequently in detached parties, resting, early in tiie morning, an hour at a time, on the tops of trees near streams of water, appearing solitary, silent, and fatigued. They continue to be occasionally seen, in small solitary parties, particu- larly along creeks and banks of rivers, so late as the middle of June ; after which we see no more of them until about the beginning or middle of October, when they re-appear in much larger rlocks, generally accom- panied by numbers of the red-wing*" (troopials) ; " between whom and the present species there is a considerable similarity of manners, dialect, and pcr- .sonal resemblance. In these aerial voyages, like other experienced navigators, they take advantage of the direction of the wind, and always set out with a favourable gale. # # * # • " From the early period at which these birds pass in the spring, it is highly probable that their migra- tions extend very far north. Those which pass in the months of March and April, can have no oppor- tunity of depositing their eggs here," (in the United States,) " there being not more than one or two of our small birds which build so early. Those that pass in M-.iy and June are frequently observed loitering about solitary thickets, reconnoitering, no doubt, for proper nurses, to whose care they may commit the hatching of their eggs and the care of their helpless orphans. Among the birds selected for this duty are the following. * * * The bluebird" (Sialia Wilsonii}, " which builds in a hollow tree; the chipping sparrow" ( Emberizoides socialis], "in a cedar bush ; the golden-crowned thrush-pipit" (Scturus auri- i-aj)illns\ "on the ground, in the shape of an oven ; the red-eyed fly-catcher" (lrirct> olivacetis), "a neat pensile nest, hung by the two upper edges on a small sapling or drooping branch; the yellow-bird" (or American gold-finch, Carduclis luteus], " in the fork of an elder ; the Maryland yellow-throat" (Triclias per- sonntus, a little bird somewhat allied to the European hedge chanter), " on the ground, at the roots of brier bushes; the white-eyed fly-catcher" (flreo Noveboracetuit), " a pensile nest, on the bending of a vine; and the small blue-grey fly-catcher" ( Culicivora cterulcn), " also a pensile nest, fastened to the slender twigs of a tree, sometimes at the height of fifty or sixty feet from the ground. There are, no doubt, others to whom the same charge is committed ; but all these I have myself met with acting in that capacity. " Among these, the yellow-throat and the red-eyed fly-catcher appear to be particular favourites, and the kindness and affectionate attention which these two little birds seem to pay to their nurslings, fully justify the partiality of the parents. " It is well known to those who have paid attention lo the manners of birds, that, after their nest is fully finished, a day or two generally elapses before the female begins to lay. This delay is, in most cases, necessary to give firmness to the yet damp materials, and allow them time to dry. In this state it is some- times met with, and laid in by the cow-bunting ; the result of which, I have invariably found, to be the desertion of the nest by its rightful owner, and the consequent loss of the egg thus dropt in it by the intruder. But when the owner herself has begun to lay, and there are one or two more eggs in the nest before the cow-bunting deposits hers, the attachment of the proprietor is secured, and remains unshaken until incubation is fully performed, and the little stranger is able to provide for itself." There is a little here at variance with the habit of the cuckoo of Europe, which is, always to destroy whatever other eggs there may be in a nest into which she introduces her own ; any eggs, therefore, which are ever found together with that of the cuckoo, have usually not been laid till after its deposition ; never, in fact, but in cases where the cuckoo had been disturbed, as she sometimes is by the proper owners of the nest, before she had had time to finish her operations ; an instance of which was once observed by the writer of this. — See CUCKOO. " The well known practice of the young cuckoo of Europe," continues Wilson, " in turning out all the eggs" (?) " and young which it feels around it, almost as soon as it is hatched, has been detailed in a very satisfactory and amusing manner by the amiable Dr. Jenner *, who has since risen to immortal celebrity in a much nobler pursuit, and to whose genius and humanity the whole human race are under everlasting obligations. In our cow-bunting, though no such habit has been observed, yet still there is something mysterious in the disappearance of the nurse's own eggs soon after the foundling is hatched, which happens regularly before all the rest. From twelve to fourteen days is the usual time of incubation of our small birds ; but although I cannot exactly fix the precise period requisite for the egg of the cow- bunting, I think I can say almost positively, that it is a day or two less than the shortest of the above- mentioned species ! In this singular circumstance we see a striking provision of the Deity ; for, did this egg require a day or two more, instead of so much less, than those smaller eggs among which it has been dropped, the young it contained would, in every instance, most inevitably perish ; and thus, in a few years, the whole species must become extinct. On the first appearance of the young cow-bunting, the parent being frequently obliged to leave the nest to provide sustenance for the foundling, the business of incubation is thus necessarily interrupted ; the dis- position to continue it abates ; nature has now given a new direction to the zeal of the parent, and the remaining eggs, within a day or two at most, generally disappear. In some instances, indeed, they have been found on the ground near, or below, the nest ; but this is rarely the case. " I have never known more than one egg of the cow-bunting dropped into the same nest. This egg is somewhat larger than that of the blue-bird" (that is to say, about the size of that of the yellow-bunting of Europe), " thickly sprinkled with grains of pale brown on a dirty w hite ground — it is of a size propor- « See Philosophical Transactions for 1788. Part 11. 1(30 COW- BUNTING. tionahle to that of the bird" — the European cuckoo's is not. " So'extraordinary and unaccountable is this habit, that I have sometimes thought it might not be general among the whole of this species in every situation, that the extreme heat of our summers, though suitable enough for their young, might be too much for the comfortable residence of their parents ; that, therefore, in their way to the north, through our climate, they were induced to secure suitable places for their progeny ; and that, in the regions where they more generally pass the summer, they might, perhaps, build nests for themselves, and rear their own young, like every other species around them. On the other hand, when I consider that many of them tarry here so late as the middle of June, drop- ping their eggs, from time to time, into every con- venient receptacle ; that in the States of Virginia, Maryland, Delaware, New Jersey, and Pennsylvania, they uniformly retain the same habits ; and, in short, that in all these places I have never yet seen or heard of their nests, — reasoning from these facts, I think I may safely conclude, that they never build one ; and that in those remote northern regions their manners are the same as we find them here. " What reason nature may have for this extra- ordinary deviation from the general practice, is, I confess, altogether beyond my comprehension. There is nothing singular to be observed in the anatomical structure of the bird that would seem to prevent or render it incapable of incubation" (nor is there in that of the European cuckoo). " The extreme heat of our climate is probably one reason why, in the months of July and August, they are rarely to be seen here ; yet we have many other migratory birds that regularly pass through P&insylvania to the north, leaving a few residents behind them, which, without exception, build their own nests and rear their own young. This part of the country also abounds with suitable food, such as they usually subsist on. Many conjectures, indeed, might be formed as to the probable cause, but all of them that have occurred to me are unsatisfactory and incon- sistent. Future and more numerous observations, made with care, particularly in those countries where they most usually pass the summer, may throw more light on this matter, till then, we can only rest satis- fied with the reality of the fact. " This species winters regularly in the lower parts of North and South Carolina and Georgia ; I have also met with them near Williamsburgh, and in several other parts of Virginia. In January, 1809, I observed strings of them for sale in the market of Charlestown, South Carolina. They often frequent com and rice fields, in company with the red-winged troopials, but are more commonly found accompany- ing the cattle, feeding on the seeds, worms, &c., which they pick up amongst the fodder and from the excre- ments of the cattle, which they scratch up for this purpose"; which, be it remarked, is often the habit of the European starling (Sturuus vulgaris). " Hence they have pretty generally obtained the name of Cow -pen-birds, Cow-Mrds, or Cow-blackbirds. By the naturalists of Europe they have hitherto been classed with the finches, though improperly, as they have no family resemblance to that tribe sufficient to justify that arrangement," &c. " Respecting this extraordinary bird," says Wilson, " I have received communications from various quarters, all corroborative of the foregoing particulars. Among these is a letter from Dr. Potter of Baltimore, which, as it contains some new and interesting facts, and several amusing incidents, I shall, with pleasure, lay before the reader, apologising to the obliging- writer for a few unimportant omissions which have been anticipated in the preceding pages." The limits, however, of this Cyclopaedia will not. allow us to transcribe the whole of this highly interesting com- munication ; we will select only a few of the more important facts, but we heartily recommend the reader to peruse the original, the details of which evince a habit of patient investigation, and a degree of philo- sophic caution, which naturalists in general would do well to imitate. " The cow-pen finch differs, moreover," says the writer, "in another respect, from all the birds with which I am acquainted. After an observance of many years, I could never discover anything like pairing or a mutual attachment between the sexes. Even in the season of love, when other birds are separated into pairs, and occupied in the endearing office of providing a receptacle for their offspring, these birds arc seen feeding in odd as well as even numbers, from one to twenty, and discovering no more disposition towards perpetuating their species than birds of any other species at other seasons, excepting a promiscu- ous concubinage which pervades the whole tribe." The same obtains in the European cuckoo. " When the female separates from the company, her departure is not noticed ; no gallant partner accompanies her, nor manifests any solicitude in her absence ; nor is her return greeted with that congratulatory tender- ness that so eminently characterises the males of other birds. The male proffers the suine civilities to any female indiscriminately, and they are reciprocated accordingly, without exciting either resentment or jealousy in any of the party. This want of sexual attachment is not inconsistent with the general eco- nomy of this singular bird ; for, as they are neither their own architects nor nurse of their own young, the degree of attachment thut governs others would be superfluous. * " By a minute attention to a number of these birds when they feed in a particular field in the laying season, the deportment of the female, when the time of laying draws near, becomes particularly interesting. She deserts her associates, assumes a drooping, sickly aspect, and perches upon some eminence where she can reconnoitre the operations of other birds in the process of nidification. If a discovery suitable to her purpose cannot be made from her stand, she becomes more restless, and is seen flitting from tree to tree, till a place of deposit can be found. I once had an opportunity of witnessing a scene of this sort, which I cannot forbear to relate : — Seeing a female prying into a bunch of bushes in search of a nest, I deter- mined to see the result, if practicable ; and knowing how easily they are disconcerted by the near approach of man, I mounted my horse and proceeded slowly, sometimes seeing and sometimes losing sight of her, till I had travelled nearly two miles along the margin of a creek. She entered every thick place, prying with the utmost scrutiny into places where the small birds usually build, and at last darted suddenly into a thick copse of alders and briers, where she remained five or six minutes, when she returned, soaring above the underwood, to the company she had left feeding in the field. Upon entering the covert, I found the COW- BUNTING. 161 nest of a yellow-tnroat" (Tr'n-has jwrwiuitus}, " with an egg of each. * * * In the progress of the cow-bird along the creek's side, she entered the thick boughs of a small cedar, and returned several times before she could prevail on herself to quit the place ; and upon examination, I found a" species of "sparrow sitting on its nest, into which she no doubt would have stolen in the absence of its owner." We may have occasion to refer to these observations when we give the natural history of the European cuckoo. "'The deportment of the yellow-throat on this occasion is not to be omitted. She returned while I waited near the spot, and darted into her nest, but returned immediately and perched upon a bough near the place, remained a minute or two and entered it, again, returned and disappeared. In ten minutes she returned with the male. They chattered with great agitation for half an hour, seeming to participate in (he affront, and then left the place. I believe all the birds thus intruded upon, manifest more or less concern at finding the egg of a stranger in their own nests. Among these, the sparrow* is particularly punctilious, for she sometimes chirps her complaints for a day or two, and often deserts the premises alto- gether, even after she has deposited one or more egg.<." Many small birds will indeed eject an alien egg from (lie nest. " The following anecdote will show, not onlv that the cowpen finch insinuates herself slily into ihe nests of other birds, but that even the most pacific of them will resent the insult. A blue- robin had built for three successive seasons in the cavity of a mulberry tree near my dwelling. One day, when the nest was nearly finished, I discovered a female cow-bird perched upon a fence stake near it, with her eyes apparently fixed upon the spot, while the bulkier was busy in adjusting her nest. The moment she left it, the intruder darted into it, and in five minutes returned and sailed off to her companions with seeming delight, which she expressed by her gestures and notes. The blue-bird soon returned and entered the nest, but instantaneously fluttered back with much apparent hesitation, and perched upon the highest branch of the tree, uttering a rapidly repeated note of complaint and resentment, which soon brought the male, who reciprocated her feelings by every demonstration of the most vindictive resent- ment. They entered the nest together, and returned several times uttering their uninterrupted complaints for ten or fifteen minutes. The male then darted away to the neighbouring trees, as if in quest of the offender, and fell upon a cat-bird," (Orpheus felivox,) " which he chastised severely, and then turned to an innocent sparrow that was chanting its ditty in a peach tree. Notwithstanding the insult was so passionately re- sented, I found the blue-bird had laid an egg the next day. Perhaps a tenant less attached to a favourite spot would have acted more fastidiously, by deserting the premises altogether." We know, indeed, from direct experiments, that when the egg of a stranger is placed into a nest before any of the owner's eggs had been deposited, the nest is most usually forsaken. Some interesting observations follow, upon the nature and disposition of the various birds into whose nests the cow-bird's egg is commonly deposited, with some remarks on the curious fact, that the eggs of the owner of the nest are never hatched, as those always are which accompany the cuckoo's egg. We need * A very different bird from the sparrow of northern Europe. NAT. HIST. — VOL. II. not here transcribe all the detail of facts that is given, but will come at once to the writer's conclusion. " How do the eggs get out of the nest ? Is it by the size and nestling of the young cow-bird ? This can- not always be the case ; because, in the instance of the blue-bird's nest in the hollow stump, the cavity was a foot deep, the nest at the bottom, and the ascent perpendicular ; nevertheless the eggs were removed, although rilled with young ones ; moreover a young cowpen finch is as helpless as any other young bird, and, so far from having the power of ejecting others from the nest, or even the eggs, that they are some- times found on the ground under the nest, especially where the nest happens to be very small. 1 will not assert that the eggs of the builder of (he nest are never hatched ; but I can assert, that I have never been able to find one instance to prove the affirmative. If all the eggs of both birds were to be hatched, in some cases the nest would not hold haJf of them ; for instance, those of the sparrow, or yellow-bird. I will not assert that the supposititious egg is brought to perfection in less time than those of the bird to which the nest belongs , but, from the facts stated, 1 am inclined to adopt such an opinion. How are the eggs removed after the accouchement of the spurious occupant? By the proprietor of the nest unquestionably ; for this is consistent with the rest of her economy. After the power of hatching then is taken away by her attention to the young stranger, the eggs would be only an incumbrance, and therefore instinct prompts her to remove them. I might add, that I have sometimes found the egg of the sparrow, in which were miniatured young ones, lying near the nest containing a cow-bird, and there- fore I cannot resist this, conclusion. Would the foster parent feed two species of young at the same time ? I believe not. I have never seen an instance of any bird feeding the young of another, unless im- mediately after losing her own. I should think the sooty looking stranger would scarcely interest a mother, while the cries of her own offspring, always intelligible, were to be heard. Should such a com- petition ever take place, I judge the stranger would be the sufferer, and probably the species soon become extinct. Why the lex natitra; (•(jnxcrcalrijc should decide in favour of the surreptitious progeny is not for me to determine." It will be seen upon a reference to our article CUCKOO, that the ingenious writer was wrong in some of these suppositions. We need not, however, here forestall our account of the various facts which we have to give concerning that interesting bird ; but proceed now to copy Wilson's description of a cow- bunting,which he reared in confinement, and must then conclude our long account of this very singular species. " In the month of July, I took from the nest of the Maryland yellow-throat, which was built among the dry leaves at the root of a brier bush, a young male cow-bunting, which filled and occupied the w hole nest. J had previously watched the motions of the foster parents for more than an hour, in order to ascertain whether any more of their young were lurking about, or not ; and was fully satisfied that there were none. Thev had, in all probability, perished in the manner before mentioned. I took this bird home with me, and placed it in the same cage with a Red-bird," (or Cardinal grosbeak, Guanca cardinatis,) " who, at first, and for several minutes after, examined it closely, and seemingly with great curiosity. It soon became cla- 162 COW- PARSNEP — CRAB. morous for food, and from that moment the red-bird seemed to adopt it as his own, feeding it with all the assiduity and tenderness of the most affectionate nurse. When he found that the grasshopper which he had brought it was too large for it to swallow, he took the insect from it, broke it in small portions, chewed them a little to soften them, and with all the gentleness and delicacy imaginable, put them separately into its mouth. He often spent several minutes in looking at it, and examining it all over, and in picking off any particles of dirt that he observed on its plumage. In teaching and encouraging it to learn to eat of itself, he often reminded me of the lines of Goldsmith — " 'He tried each art, reproved each dull delay, Allur'd to 'fav'rite food,' and led the way.' " The sight, however, of a young helpless nestling operates wonderfully upon the instinctive feelings of most birds, however dissimilar may be the species, of which a very striking instance has been already given in our article BOTTLETIT. " This cow-bird," continues Wilson, '• is now six months old ; is in complete plumage ; and repays the affectionate services of his foster-parent, with a fre- quent display of all the musical talents with which .nature has gifted him. These, it must be confessed, are far from being ravishing ; yet, from their singu- larity, are worthy of notice. He spreads his wings, swells his body into a globular form, bristling every feather in the manner of a turkey coek, and, with great seeming difficulty, utters a few low spluttering notes, as if proceeding from his belly; always, on these oc- casions, strutting in front of the spectator with great consequential affectation. " To see the red-bird, himself so excellent a per- former, silently listening to all this guttural splendour, reminds me of the great Handel contemplating a wretched catgut-scraper. Perhaps, however, these may be meant for the notes of love and gratitude, which are sweeter to the ear, and dearer to the heart, than all the artificial solos or concertos on this side heaven." Here we cannot but remark that the males of nearly all sorts of polygamous birds exhibit some sort of curious display in uttering their notes. Thus, the grouse (Tetrao), spread their tails and strut, whilst the nearly allied, but monogamous, ptarmigan (Lago- pus\ do nothing of the kind. Almost all birds that spread out their plumage, like the peacock and turkey, are polygamous. Indeed, birds that never pair are generally distinguished by supernumerary feathers, or by having particular parts of their plumage unusually produced. Thus, the Ruff (Machetes pugnax] is the only known species of the sand piper and plover tribes which is polygamous; and it is the only one which is distinguished in summer by a remarkable develop- ment of feathers about the head and neck. So the bitterns are the only known polygamous birds of the heron kind, and these are similarly distinguished. The bustards also are polygamous, and the males of these have accessory plumage in summer ; and common poultry are polygamous, the males of which have many feathers of their much produced. But the rule does not invariably obtain : many pheasants and polyga- mous species of ducks exhibit no kind of display, and the monogamous partridges are not thus to be distin- guished from the polygamous quails ; and inversely, in certain humming-birds and others, which are known to pair, the males have a very splendid display. The rule, however, is sufficiently general to allow of its being worthy of remark. COW-PARSNEP is the Herackum sjihondyUum of Linnaeus. This is one of our largest herbaceous plants, and known by the provincial name of kex or kexes. It is very common in damp meadows, and as its seeds are always shed when hay is made, it is liable to usurp too much room in the turf. Grazing the meadow for a few consecutive years is the .best way to get rid of it, because the leafy point of the stems is nibbled off by the sheep as soon as they shoot up. It is a very coarse plant in hay, though it docs not, appear to be ungrateful to cattle. Cow-parsley is another Heracleum, but which is a native of Siberia. COWSLIP is the Primula verts and vu/garis of Linnaeus. If any one plant is better known than another it is this; every child knows the cowslip ; and notwithstanding its being so common, and in favour- able spots in such great profusion, it is always welcomed and admired. There are several unnoticed varieties of this plant; and it is allied to a numerous family, of which the auricula, polyanthus, and primrose are the chief; all which are described under the proper names, and in that of the natural order to which they belong. A kind of wine is made from the flowers of the cow- slip, which, it is said, is particularly efficacious as a febrifuge. CRAB. The ordinary English name by which many of the larger species of the Crustacea are dis- tinguished, and to which in the Linnaoan system the name of Cancer was applied. The term however is not exactly synonymous with the latter name, as the lobster, cray-fish, shrimp, prawn, &c., formed portions of the LinnsDan genus. Since the time of Linmvus, however, the study of these animals has greatly in- creased, so that the two Linna^an genera, Cancer and Monoculus, have been raised to the rank of a distinct class composed of several orders, one of which, the Decapoda, or ten footed Crustacea, comprises two principal divisions, the Brachyura, or those of a broader form and with short tails, and the Macronra, having an elongated form and a more developed abdomen. In the former division, the animals known by the ordinary name of crabs are placed, whilst the latter comprises the other species above mentioned ; still, as if to show the total disagreement of the ordi- nary terms in natural history with their scientific limits, the king crab of the tropical seas belongs to a totally different order of Crustacea than either of those above mentioned, whilst even the hermit crab belongs to the macroura. Crabs are for the most part marine animals, fre- quenting the rocky shores of the ocean, and having the body generally broader than long, although in a very few instances the reverse takes place. As, however, the general structure of the crabs will be found detailed under the article BKACHYDRA, we shall here confine ourselves to a few general observa- tions upon the habits of the order. We regret their paucity, owing as it is to the very slight attention which has been paid to the habits of marine animals. This class of animals, as compared with that of the true insects, is very limited in its extent, but many of the species far exceed in size any of the great division of annulose or ringed animals, whilst some of them are very minute. They are found in all latitudes, but are more abundant in the warm and temperate climates than in more northern regions. Some genera, as Ocypode, Gecarcinus, Uca, Grapsus, &c., frequent more southern regions, being found in nearly equal latitudes in the different parts of the old and new CRABRO— C R AM BE. work'.. Others, as the true crabs, Partunns, &c, are more generally distributed, extending from the equator to the polar circles. The local habitations of these animals are, however, very varied. Some few species of crabs penetrate to a considerable distance inland, but are compelled to return to the sea at the period of coupling and ovipo- sition. Other species, although having the form of the marine crabs, do not, emit the fresh water, as in the Tflphusff. Again, amongst the marine species, the majority do not quit the shores, whilst others are found at great distances in the high seas, where they can rest only on the floating banks of sea-weeds so abun- dant in the tropics. And even in those species which frequent the coasts, the same situations arc not con- genial to them all; some, as the Dorippe and Inachi, reside at great depths of the sea, from two to four hundred feet, whilst others keep continually at the surface of the waters, passing a great part of their existence upon the shores continually washed by the waves. Some species, again, frequent only the rocky parts of the coast, abounding in madrepores and diffi- cult of access, whilst others prefer sandy shoals, in which they bury themselves. Amongst the land crabs some species, as the Ocypodc^ make deep burrows, at the mouth of which they ordinarily take their station after the fashion of sentinels, whilst some, as the Raniiuc, prefer more elevated places, and sometimes even mount the roofs of the huts of the Indians. The crabs are, moreover, the most active animals of the class with reference to their powers of walking, although the Maaroura cer- tainly excel them in swimming. In those crabs which run fastest the eight hind legs are alone employed, and arc terminated by strong pointed hooks. They walk with the same facility, forwards, backwards, and from side to side, indeed in all possible oblique direc- tions. They will also ascend inclined planes, and even almost perpendicular surfaces, provided these planes be not quite smooth. Many, as the Ocypode and (irrarrini, are noted for their rapidity in running; indeed it is said that a. man at full speed would be unable to overtake them. Many species of crabs walk with much less agility than the others, being more decidedly aquatic. They are therefore provided with dilated legs, having the margins furnished with rows of hairs, which are thence converted into natural oars, and by the assistance of which these species are able to perform the same motions in the water as the others do on the shore, and in equally varied direc- tions. Such are the Podophlhalmi, ^'lututcc, Portuni, &c., which have hence acquired the name of shuttle crabs, Cancer vocans. Crabs are in general very courageous, and when their retreat is cut off they stretch out their claws, and endeavour to nip with them, which they do with much force, owing to the size of these parts. Some species, in shutting these claws with violence and rapidity, produce a strong sound ; and as they hold their claws in the air with which they make this noise, they have fancifully obtained the name ol Calling Crabs. Crabs, fcs well as the generality of the class Crus- tacea, feed upon animal matter, especially when in a state of decomposition. Dead bodies, floating upon the surface of the waves, or cast upon the shore by them, are immediately covered with these animals, and there is every reason to suppose that they are attracted by their powers of scent, although the seat of this sense is not known. Some of the carnivorous crabs even attack living prey, and fight fiercely in order to procure it. In these combats they often lose their claws, which are however soon reproduced, but they never attain the same size as previously. This reproduction of the limbs is one of the most curious circumstances connected with the class, and respect- ing which we shall give further details in our obser- vations upon the class. In like manner \v.: shall reserve the account of the transformations which these animals have recently been asserted to undergo by Mr. J. V. Thompson, in his valuable Zoological Researches, as well as an account of the periodical moulting undergone by them. CRABRO (Geoffrey). A genus of hymenopterous insects synonymous with CIMBEX. CRABRONIDjE (Leach). A family, or perhaps rather a sub-family, of hymenopterous insects belong- ing to the section Aculcata and subsection Fossores or false wasps. The head is large and nearlv square, seen from above; the antennae often gradually thickened at the tips ; the abdomen oval or elliptic, broadest at the middle, or narrowed at the base into a peduncle. The insects introduced into this family may be divided into two distinct sections with refer- ence to their natural habits,which are verv interesting : first, the true burrowers, which form their own nests, either in the sand or in decayed rotten posts, and similar situations ; these have the fore-legs in gene- ral armed with strong spurs to enable them to perform their laborious operations in the construction of their nests ; and, secondly, the species which are destitute of these spurs, and which consequently being unable to make their own nests, deposit their eggs in the nests of the other species, and in which the parent fly has already deposited a supply of food consisting of other insects, upon the bodies of which, as well as also (in all probability, although the point has not yet been decided) upon the real inhabitant of the cell, the larvae hatched from the eggs thus surreptitiously introduced into the cells feed. The genera are, Try- poxylon, Latreille, which provisions its nest with small spiders ; Gorytes, which are considered para- sites ; Crabro, which generally burrow in wood, and provision their nests with the caterpillars of small moths found upon the oak, as well as with dipterous flies*. Some of the male have the anterior tarsi dilated into a curious circular plate ; Stigmus and Pemphrcdon, which burrow in sand, one of the species of the latter burying numbers of plant lice for the food of her future progeny ; Mellintis, All/son, Psen, Philanthus, the larva of which is supplied with bees ; and Cer- ceres (which see for a more detailed account of the habits of the last two genera). CRAMBE (Linnaeus). A genus of herbaceous perennials, one of them a native of Britain, and known by the name of sea-kale. These plants belong to the class Tctradynamia, and natural order Cruciferae. Sea-kale is found wild on sandy shores, and as it rises with large succulent shoots and unexpanded leaves early in the spring, had been long used as a substitute for young cabbage by the country people in those places where it was plentiful. Near four- score years back it was brought, though partially, into garden culture ; but was in little esteem till about * We liave just noticed one of the species of this genus flying rilont; with a crane fly, larger than itself, the legs ol' which It had previously cut off. L -2 164 CRAMBUS — CRANBERRY. 1794, when being then found to be no bad substitute for forced asparagus, particularly at the best tables in the city oi' Bath, it came suddenly into high repute, and consequently has been extensively cultivated ever since as well in public as in private gardens. The ease and certainty with which it may be forced, so as to have a regular supply throughout the winter, is an additional recommendation, and especially, as it is found to be a suitable supper dish for persons of weak constitutions, and who cannot, at that meal, partake of any kind of animal food. The plant may be grown luxuriantly in any soil, provided it is loose enough ; but its excellence, as a condiment, depends not on its bulk, but on its mild flavour, and therefore means must be taken to grow it in the poorest soil, even pure sand, in order that the naturally rank cabbage flavour may be corrected. Sea-kale is usually cultivated on beds or borders in any open part of the garden. The body of the bed may be composed chiefly of sea or river sand, to the depth of twelve or fifteen inches. The surface of the bed may be four or five inches lower than the general level of the ground when the seeds are sown or when roots are planted, and then covered with an inch of pure sand. When seeds are used, they are dropped along the middle of the bed in patches, two feet from each other, three or four good seeds together. If they all rise, reduce to two or three at each place, and in the future management, it should be endeavoured to keep the crowns of the plants always as low and near together as possible, for the purpose of covering them with pots or otherwise, when necessary. The roots, particularly on the upper parts, are thickly studded with buds, so that, notwithstanding the annual loss of the crowns, other shoots are soon afterwards produced from below. This peculiar pro- perty of the roots rentiers a new plantation of sea kale easily made, and which will come as soon into use as if seed had been sown. Either method may, there- fore, be followed ; and before the winter sets in, the plants will have arrived at a considerable size. All the shoots have a tendency to rise, and the crowns which are to be relied on for the following year's crop, will remain an inch or two 'higher than the surface after the leaves are shed. This circumstance requires that the crowns be covered with an additional layer of sand, through which the young eatable shoots will protrude in the spring of the following year. If it be wished to have any strong stools, refrain from cutting any in the second year; but if the plants have grown vigorously the first year, a few dishes may be taken without injury. Many schemes have been practised to induce an early growth of the shoots, because, if the kale do not come in before asparagus.it will be but little esteemed. Deep coverings of pure sand, of coal culm, of decayed light dung or leaves of forest trees, to the depth of a foot or more, have all been used with various success. One of the most common modes is covering the crowns with large garden flower pots, and heap- ing around and upon these, a ridge of hot stable dung that has been previously prepared by frequent turnings to dissipate the rank steam and heat. The heat im- parted from the covering excites the plants into action, and by this means sea-kale may be had in any of the winter or spring months, provided the beating substance be applied seven weeks before the hale is wanted. Other and equally efficient plans for forcing the crop have been executed. Single rows of plants are put in along the middle of two-feet-wide beds, having two-feet-wide alleys between. The alleys are dug out to the depth of eighteen inches, and the sides of the beds are kept up by open or pigeon-holed brick- work. Six or seven weeks before the kale is wanted, any required length of the beds have the alleys filled with hot dung, and the crowns being covered with pots, hand glasses, or wooden troughs, made for the purpose, and covered over the crowns with additional coverings of mats in severe weather, brings up the shoots expeditiously and in their purest state, neither tainted by the effluvia of the dung, nor discoloured or soiled by any matter in contact with them. Neither air or light are necessary to the shoots ; perfect blanching not only improves its appearance when dressed, but its flavour also in a considerable degree. It may be repeated, that its excellence entirely depends on the poverty of the soil in which it is grown, and its perfect etiolation. Sea-kale may be raised on very rich soil and of very great size ; but few ladies could sit at the table on which it is served up. But this plant may be conveniently forced in pots, either in a hot-house, hot-bed, or even in any warm corner of a kitchen. Large pots are filled with stout roots among light earth or sand ; another pot of the same size is inverted over the first ; in this dark prison the shoots are produced, equal in delicacy, though not in quantity, as they can be by arty other means. The proper temperature for sea-kale experi- ence has taught is about 55° of Fahrenheit. CRAMBUS (Fabricius). An extensive genus of small lepidopterous insects, respecting the family of which there is some uncertainty, Mr. Stephens placing them in the Tineidce, Mr. Curtis in the Pyralidte, and Latreille forming them into a family termed Crambitcs. They are very active, abounding in pastures, and amongst grass, upon the stalks of which they generally rest with their heads downwards and their wings very closely applied, in a convoluted manner, to their bodies,so that they were originally termed close-winged moths, their appearance being nearly that of a cylinder. They take flight very readily at our approach, but soon settle again. The upper wings are long and narrow, their antennae simple, the labial palpi are stretched forwards, the maxillary spiral tongue is long and slender, and the maxillary palpi very distinct and raised in front. There are nearly forty British species, including the type Phalcenn Pascuella, Linnaeus. Some of them are so exceedingly abundant that scores are disturbed in certain situations at every step. We do not remember ever to have met with them in such abundance as in the month of August on the exposed sides of the Hill of St. Catherine, at the back of the Isle of Wight. Their colours are pale, and they are often ornamented with silvery markings. CRANBERRY, is the Oxycoccus Palustm of Persoon, and the Vaccinium Oxycoccus of Linnseus, a common British plant, found on turfy bogs. The fruit of this plant is very generally employed as a kitchen article for tarts. Both the British and American long-fruited cranberries are gathered for sale, and large quantities are annually imported from North America. The late Sir Joseph Banks advised the garden culture of the American species, and several gardeners have been extremely successful in the attempt. Much CRANE FLY— CRASSATELLA. 165 depends on the possession of a suitable site to grow the cranberry. A piece of turfy bog-, by the side of a pond, is the natural situation ; or an artificial border of bog-earth may be formed, on which there may be no fear of the plant succeeding. This latter project, however, can only be justitied by comparing the cost of home-growth with that charged by the retailers of the fruit in this country. CRANE FLY, one of the names by which the larger species of the dipterous insects belonging to the family Tipitliclat are generally termed ; they are also called daddy long legs, tailors, &c. They are very abundant in pastures, especially at certain sea- sons of the year, as at the end of the summer, when they rise in swarms on being approached. Their long le ith members of the Cephalopoda, and always found they were driven from their society, and obliged to congregate in a different part of the same space to which they were confined ; observing also, that when one of these intruders presented itself, or had wan- dered outoi'its assigned limits, the Common Cuttlefish particularly, exhibited, as it were, immediate signs of uneasiness. That peculiar breathing kind of motion, which resembles the exhaustion and filling of their bladder-formed bodies, became more rapid ; their ten- tacular appendages much agitated ; and, in a few seconds, the whole of the family were in motion, oc- cupied in driving the stranger from amongst them, all united as it were in a common cause against the sup- posed enemy. Their movements, however, upon thi /occasion were by no means rapid ; on the contrary, they seemed guided by a regularity of purpose gene- rally understood to themselves, and it might almost be imagined directed by a recognised commander — they never assailed the intruder, each after his own fashion surrounding it promiscuously, but clearing a passage, left ample space for retreat ; and then, from the nearest to the most distant point, they closed in and prevented its intrusion. In this movement much purpose was exhibited, for the Sepia: did not form them- selves into a solid mass, but each of them appearing to have a place allotted to it, moved nearer to the sphere of action, with something like regularity; each one pre- pared and in motion, but not going far from the spo in which it had been reposing : the impulse of alarm appeared general, but rather to excite caution thar anger, though the result invariably was the same, tha of precluding the stranger from entering into thei congregation. These observations were made on i part of the Dutch coast, where some acres of marsh land were overflowed each tide ; and the situation being, doubtless, favourable to these creatures, their numbers were countless — the whole space exhibiting a palpitating moving mass of creatures, in some parts so closely packed as to have the appearance of form- ing but one animal. Professor Kops, of Amsterdam, visited the spot in the summer of 1816 ; and his inte- esting remarks on this occurrence form a paper read it an academic meeting in Holland. The following ?ear, however, the same spot was deserted, and not a ingle sepia to be seen there. The body of the animals of this order are enveloped and partly free, in a very thick mantle, expanding into a wide opening at its anterior side ; the edges free, and detached all round, looking like a sack or opened Bladder, without any trace of muscular abdominal disc, or of a foot ; this body is most generally naked, either unprovided with solid internal parts, or inclosing a shell or other hard substance ; sometimes provided with an external substance or testaceous portion, co- vering or sheathed in the body. This is never com- posed of two opposite valves, its shape is extremely various ; it is placed dorsally, and serves as a shield or protection to some of the more delicate organs. The animal is completely inarticulate, provided with a very large head, more or less projecting ; this presents ibur or five pairs of conical tentacular appendages at- tached at their base to a kind of skull which envelops the brain, and are furnished with suckers used for prehension : these arms are disposed in a circular order, in the form of a coronet. The mouth is alto- gether anterior, elongated or tubular ; armed with a large pair of horny teeth in the form of a parrot's beak, acting vertically against each other. The mantle is diversified ; the gills or organs of respiration various ; rarely symmetrical, lateral, and concealed in the sac ; the circulation is double, one particular, the other general ; the heart unilocular, sometimes with the au- ricles divided, and very distant ; no medullary cord along the body, but provided with a few scattered nerves and ganglions. This oxler includes the genera Octopus in the first family, and the second family Dccacera, contains the Lvligo and Sepia. They are abundantly found in the seas of all countries, and probably larger and more numerous in those of warm latitudes, where marvel- lous stories are related of their gigantic structure ; they, however, are so much involved in ignorance and mystery, resting only on the uncorroborated testimony of incompetent judges, that though we are not in a position to contradict them positively, we are unwil- ling to receive them as well-established facts. Not that we absolutely reject the possibility of much we have heard respecting them being true, for every in- stant of our existence brings to light new discoveries in the animal kingdom, elucidating the phenomena of nature ; and we have constantly had occasion to re- mark, that marvellous as many of the tales of olden times at first appeared, they more or less have origin- ated in a simple matter of fact, distorted or magnified by subsequent narrators, and disguised at all times by ignorant credulity, which eagerly adopts that which cannot easily be disproved. We are, however, as we have just stated, cautious without being incredulous ; never forgetting that Bruce's Abyssinian beefsteaks drove him from society, and broke his heart by slow degrees. We have also the assertion before our eyes of a recent delightful writer, who says he is really 188 CRYPTOCEPHALUS — CUCKOO. fearful that his truth would be doubted if he were to relate some of the scenes he had witnessed ; and he has actually confided his information to such only as know his integrity, leaving future travellers to conHrrn his assertions. We can fully appreciate this feeling, and honour it ; but were all mankind to be actuated by similar delicacy, no progress would be made in elucidating the phenomena of nature — science must cease to advance, and ignorance become perpetu- ated. First impressions are readily received, and fre- quently remain deeply impressedi but a well consti- tuted mind hesitates to admit them, without having minutely weighed the mass of evidence for or against them, and exercising a sound discretion as to its worth. It would be travelling far out of our prescribed path, to enumerate the thousand instances we might easily adduce, in which a description of nature and her operations would be treated at first sight as the idle dream of a disturbed imagination, or a tale of poetic fancy. This applies to every portion of crea- tion, but to none more universally than to entomo- logy; in which the insect transformations, their habits, and their ordained purposes, have become additional proofs of omnipotent wisdom, through the laborious investigations of a host of eloquent writers on the sub- ject, from an early period, down to those of the vene- rable Kirby and others of our own time. With such examples, we dare not reject any thing as impossible to the Architect of nature ; but we are slow to give implicit credence to all we hear, unsupported by the clearest concurring testimony. Cephalopoda — the name given to these animals by Lamarck, Cuvier, and other modern naturalists — is de- rived from two Greek words.implying the feet socalled, being placed on the head. Cryptodibranchiata means the animal's two branchiae being concealed. Ceplialopod is, however, the commonly received term, and is more expressive, as indicating a character which readily strikes the senses, without requiring any additional information from anatomical examination, to guide the first step towards a system of classification. CRYPTOCEPHALUS (Geoffrey). A genus of coleopterous insects of considerable extent, belonging to the family CHRYSOMELID*:, which see," having the antennae long and slender, head small' and vertical, the body short, thick, and cylindric, and legs formed for walking. They are of a small size, seldom reach- ing half an inch in length. Their form is not elegant, but they are compensated by the beautiful colours and markings with which they are adorned. They are found upon flowers in the hot sunshine, and feed, both in the larva and perfect state, upon vegetable matters ; destroying the young buds, they do not cut, but macerate, and occasion them to dry up" arid fall. When disturbed they have recourse to artifice by folding their antennae and legs close to the body, and counterfeiting-death. At a late meeting of the Entomological Society of France a larva found in an ants' nest, enclosed in a solid case, was described, and which was considered to be that of a species of this genus. M. Gene of Turin has also published some interesting observations upon the larva? of the Crypto- cephalus. Dejean, fourteen years ago, enumerated seventy species, since which the number has greatly increased. There are about twenty inhabitants of this country, amongst which the type, Chrysomela sericea of Linnaeus, is one of the prettiest species, being of a fine silky golden green colour with black antenna? ; it is about one-third of an inch long, '.nd it found upon umbelliferous plants in June. CRYPTOSTEGIA(R. Brown) is an East Indian genus belonging to Penlundna Digi/nia, and to the natural order Apocynea:, according to Sweet and Sprengel, but to Asclepiade disproportionately small, the young cuckoo grows very rapidly in the nest, and its diminutive foster parents are obliged to labour hard and perseveringly to satisfy its increasing voracity ; it requires even to be tended for a longer period than any other birc with which we are acquainted, remaining five or six weeks in the nest ; and even long after it has flown its assiduous nurses may be seen to follow it with food ; and in confinement it will very rarely feed o: itself till it is two or three months old ; at all times indeed, even when able to pick up its own food, prefer- ring to be fed by those to whom it is accustomed. In a wild state, the young cuckoo that has begun to fly, however it may seek to hide itself, may generally be traced by a concourse of numerous small birds chat- tering around it, among which the swallow kind are mostly very conspicuous, seemingly endeavouring, to the utmost of their power, to annoy it ; amidst all which turmoil the pair that have brought it up con- tinue constantly to bring it caterpillars and other insects. A writer observes of one, in the Magazine of Natural History, that " it was seen again on June 12th, on the top of a wall near to the nest ; and, while it was sitting here, an amusing and instructive sight presented itself. A thrush, which probably had a nest close by, in an adjoining garden, evinced the most passionate and marked antipathy toward the young cuckoo, by approaching it with feathers ruffled, beak open, and uttering an earnest cry ; some small birds too drew near, as if to exhibit their dislike, and abet the thrush. This is indeed quite an ordinary fact ; small birds seem to consider the young cuckoo as an enemy, and they persecute it with the same unremitting hostility, and chatter round it with the same unwearied pertinacity which they exhibit toward a weasel or an owl. This is the more singular, as these very birds may, in their turn, themselves become the nurses of a young cuckoo. The same animosity is shown by the different swallows towards the old bird, which they frequently attack and buffet as it flies along. The cuckoo's food consists principally of insects, chiefly however the larger caterpillars, whether smooth or hairy ; these it first kills, by shaking and knocking them violently against the bough on which it is perched, and then renders them perfectly pliant by passing them several times through the bill, before it swallows them. In confinement it seems very fond of the common house-fly, which it will readily take from the hand of a person it is accustomed to. It also feeds largely in spring upon the common may chaffer (Melolontha vulgaris), and has been seen to capture dragon flies on the wing. As the summer advances it will attack various kinds of^fruit, as cher- ries and currants. Most probably also, as has already been mentioned, it devours birds' eggs ; but cater- pillars are its principal and main food, the exuviae of which it casts up in the manner of a hawk, in pellets, about the size of a sparrow's egg. It is in search of these that the cuckoo is so often seen about fruit trees, to which it doubtless renders an efficient ser- vice, as it not only preys upon those which have grown to some size, but also, in the spring, may be frequently seen deliberately picking out the newly hatched larva? from their webs ; an operation which has strangely enough been construed by many gar- deners and others into " sucking the blossoms," if any meaning can be attached to this phrase. Whilst feeding upon a tree, the cuckoo leans very forward upon the bough on which it is sitting, as it examines the foliage for caterpillars, its tail being generally raised ; and it frequently takes very consi- derable leaps from bough to bough, considering the shortness of its legs. The writer of this has never seen it climb in any sort of way, nor walk up a branch, using its feet alternately ; but conceives that the only use of its having two toes on each foot placed back- ward, is to enable it more firmly to grasp its perch whilst leaning so very forward. " The tree cuckoos," observes Sir W. Jardine, " though often found near woods, and in richly clothed countries, are fond of open and extensive heaths or commons, studded or fringed with brush and forest : here they may expect an abundant supply of the foster parent to their young. Their gliding and turning motion, when flying in a thicket, is simi- lar to that of the American Coccyzus. Like them, also, they are seldom on the ground ; but when obliged to be near it, alight on some hillock or twig, where they will continue for a considerable time, swinging round their body in a rather ludicrous manner, with .lowered wings and expanded tail, and uttering a rather low monotonous sound, resembling the kowe of the American bird — ' Turning round and round with cutty-coos " When suddenly surprised or disturbed from their roost at night, they utter a short tremulous whistle, three or four times repeated ; and it is only on their first arrival, during the early part of incubation, when in search of a mate, that their well-known and wel- come note is heard : by the first of July all is silent." It is not, however, very often that an opportunity occurs of studying this bird's habits so very minutely; all are acquainted with its note, and there are few persons residing in the country, but must have often observed it, as, somewhat in the manner of a pigeon, but less steadily, it wings its way from tree to tree ; but the bird is so vigilant and shy, that very few even of those who try to study its habits, can ever get to notice it more particularly, excepting, perhaps, by mere accident, once or twice only in their lives. When first taken from the nest, the young cuckoo is extremely savage and voracious, buffeting and spar- ring with its wings like a gamecock, and uttering all the time a shrill cry. They are easily enough reared upon raw meat, but are difficult to keep through the winter, being very tender about the moulting period, which usually takes place about January. In the ourse of a little time, they mostly become tolerably attached to those they know, but are generally very before strangers. Buffon, indeed, says, " though cunning and solitary, the cuckoo may be given some sort of education. Several persons of my acquaint- ance have reared and tamed them. They feea them on minced meat, either dressed or raw, insects, eggs, soaked bread, and fruit. One of these tamed cuckoos mew its master, came at his call, followed him to .he chace, perched on his gun, and if it found a cherry tree in its way it would fly to it, and not return till it had eaten plentifully ; sometimes it tvould not return to its master for a whole day, but bllowed him at a distance, flying from tree to tree." The writer of this article has seen a pair that were CUCKOO. 195 tolerably tame, that were allowed the free range of a large kitchen, where they commonly used to sit upon the fender, warming themselves by the fire. They are apt in confinement to suffer very much from ex- cess of the migratory feeling, which not unfrequently causes the death of those that are prevented from following this natural impulse. Upon the whole this species exhibits, when in a state of confinement, a greater degree of attachment to its feeder than we should be prepared to expect. Its brain, we may remark, is very small, scarcely weighing twenty grains, which only exceeds the weight of one of its eyes by a grain and a half. The old cuckoos are always the very first of our summer migrants to leave the country, as the majority of them retire southward in the first week in July. Woodmen and others say that they congregate, be- fore taking their departure, in flocks of twenty or thirty ; and the writer of this is likewise informed, upon very good authority, of a flock of sixteen young ones being seen, in September, in the north of Scot- land, flying in a south-easterly direction towards the German ocean, which, at the place of observation, was distant about half a mile. It is probably only in the less populous districts that this can ever be ob- served. Where the mass of them spend the winter has never been specifically ascertained, though speci- mens have been received from Egypt. " Naturalists," says Mr. Selby, " have been puzzled to account for this bird not performing the office of incubation, but as their researches have principally been directed to the anatomical structure, in which point it does not essentially differ from many others that perform this office, we arrive by these means at nothing satisfactory. The above peculiarity of this remarkable genus must not probably be looked for in any principle of conformation, but must be explained from their habits and economy. " Let it be remembered these birds are migratory, and that he period during which the adults remain with us if very short ; but the propagation of the species rcust be effected during that period. Now, as their arrival does not take place before the month of April, and the egg is seldom ready for incubation before trie middle of May, there would not be a suffi- cient length of time for the young to be hatched, or (making every allowance) sufficiently fledged to ac- company the old birds at the period of their departure, which seldom or never extends," in the north of England, " beyond the first week in July." This perhaps is about as good an explanation of the cuckoo's peculiarities as has hitherto been offered, but it fails, like all the rest, in being quite inapplica- ble to the case of the North American cow-bunting. The true cause (whatever that may be) of this extra- ordinary deviation must, we are persuaded, be the same in both ; nor can we at present consider any explanation as satisfactory that will not alike apply to either. That the old cuckoos, however, should retire southward in the very hottest part of the sum- mer is certainly a very curious matter, and the cause of this requires further investigation. It cannot be for want of food, for they are then always in prime condition ; and caterpillars, their main subsistence, are then much more abundant than when they arrive in spring. No observations, however, have as yet been made upon the cuckoo in its winter quarters, and till this has been done it is of little use attempting to theorise upon the subject. The natural history ol this remarkable bird still offers a wide field for inves- tigation, and it will probably be a long time yet before our knowledge of it can be any thing like complete. It is, without exception, the most extraordinary bird ;hat occurs on the European continent, and as such ;t merits peculiar and close attention from all who take an interest in natural history. Observations upon it must be multiplied, both at home and abroad, and a great deal must yet be elicited, before a variety of points can be cleared up on which at present we have little more than conjecture. Of the genus Cuculus, a considerable number of species are enumerated, inhabiting different parts of the eastern continent, but chiefly Africa, and varying in size from double that of our bird to less than half. We know, however, very little of their habits, and nothing but what is in entire accordance with those of the species which inhabits Europe. Like it, they are all understood to deposit their eggs in the nests of other birds, but the fact, we believe, has not been ascertained in more than one or two, and even in these rests as yet on the authority of a single observer. Instead, therefore, of entering here into a long detail of colours and proportions, which are very little inte- resting to the general reader, we will pass on at once to give a brief account of their American representa- tives, the members of the genus Coccyzus, which, with one or two exceptions in Africa, are all confined to the western division of the globe ; and we do this the rather, as our account of the European cuckoo has been extended to a very considerable length. The Coccyzi, as a group, are mostly rather smaller than the true cuckoos, which in their general appear- ance they much resemble. The bill is, however, rather larger in proportion, and the tarsi longer, and bare of feathers. Their plumage is generally rufous on the upper parts, white beneath, and more or less marked, with white upon the tail ; and, unlike the cuckoos, the young much resemble the adults. They are rather more confined to the interior of woods than the true cuckoos, and they build their own nests, and rear their young. Several beautiful species are found in South America, and two in the northern division of that continent, one of which has been already mentioned as an occasional straggler to the British islands. This bird, the Coccyzus Carolinensis, is thirteen inches long, and sixteen in extent of wing, the whole upper parts are of a dark glossy drab, or what is commonly called a quaker colour, with greenish silky reflections ; inner vanes of the wings bright reddish cinnamon. Tail long, composed of twelve feathers, the two middle ones being the same colour as the back, the others, which gradually shorten to the ex- terior ones, are black, largely tipped with white ; the two outer ones scarcely half the length of the middle ones. All the under parts pure white, the feathers covering the thighs (tibia}) being long, as in the hawk tribe. Legs and feet light blue. Bill dusky black above, and yellow below. Irides hazel, with the eyelids bright yellow. The female much resembles the other sex, but has four of the middle tail feathers like the back, and her white is not quite so pure. " A stranger," says Wilson, " who visits the United States for the purpose of examining their natural pro- ductions, and passes through our woods in the month of May or June, will sometimes hear, as he traverses the borders of deep, retired, high timbered hollows, an uncouth guttural sound or note, resembling the syllables koiue, fcowe, fcowe-kowc-fcowc, beginning N 2 19G CUCKOO. slowly, but ending so rapidly that the notes seem to run into each other, and vice versa ; lie will hear this frequently without being able to discover the bird or animal from which it proceeds, as it is both shy and solitary, seeking always the thickest foliage for con- cealment ;" a trait in its character, by the way, closely reminding us of the European cuckoo. " This," con- tinues Wilson, " is the yellow billed cuckoo (Coccyzus], the subject of the present account. From the imita- tive sound of its note, it is known in many parts by the name of the Cow-bird; it is also called in Virginia the Rain-crow, being observed to be most clamorous immediately before rain. " This species arrives in Pennsylvania from the south about the 22nd of April, and spreads over the coun- try, as far at least as Lake Ontario ; it is numerous in the Chickasaw and Choctaw nations, and also breeds in the upper parts of Georgia ; preferring in all these places the borders of solitary swamps and apple orchards. It leaves us, on its return southward, about the middle of September." Mr. Audubon adds, that " in their migrations northward they move singly, but when removing again to a warmer latitude they appear to be gregarious, flying high in the air, and in loose flocks." This tends analogically to confirm what we have already advanced concerning the European cuckoo's migration. That species seems also to arrive singly, and to depart southward in small flocks. " Early in May," says Wilson, " they begin to pair, when obstinate battles take place among the males. About the 10th of that month they commence build- ing. The nest is usually fixed among the horizontal branches of an apple tree ; sometimes in a solitary thorn, crab, or cedar, in some retired part of the woods. It is constructed with little art, and scarcely any concavity, of small sticks and twigs, intermixed with green weeds, and blossoms of the common maple. On this almost flat bed the eggs, usually three or four in number, are placed ; these are of a uniform green- ish blue colour, and of a size proportionable to that of the bird. While the feirfale is sitting the male is generally not far distant, and gives the alarm, by his notes, when any person is approaching. The female sits so close that you may almost reach her with your hand, and then precipitates herself to the ground, feigning lameness, to draw you away from the spot, fluttering, trailing her wings, and tumbling over, in the manner of the partridge, woodcock, and many other specie*." We cannot but contrast this affec- tionate display of parental feeling with the conduct of the European cuckoo. Some writers, however, as Dr. Darwin and others, even state of that species, that it sometimes builds a nest and rears its own progeny ; but the instances they mention clearly show thai they had mistaken a very different bird, the nightjar, for a cuckoo ; the accounts which they furnish accord entirely with the nidification of that species, which indeed in the nest bears no inconsider- able resemblance to it ; and the writer of this has himself known an instance of a young nightjar being mistaken for a cuckoo. Still it would be interesting, before we entirely divest the European cuckoo of 'all parental affection, to try whether an old caged one would take any notice of a nestling of its own species that was placed along with it ; to see whether it would be moved, like other birds, by its helpless cries, and ever place food into its mouth. We should imagine, however, that it would not. " Both parents," continues Wilson, "of the Carolina Coccyzus unite in providing food for the young. This consists, for the most part, of caterpillars, partirulariv such as infest apple trees. The same insects consti- tute the chief part of their own sustenance. They are accused, and with some justice, of sucking the eggs of other birds, like the crow, the blue jay, and other pillagers. They also occasionally eat vuiiuiis kinds of berries. But, from the circumstance of de- stroying such numbers of very noxious larvae, they prove themselves the friends of the farmer, end are highly deserving of his protection. " In examining this bird by dissection, the inner membrane of the gizzard, which in many other species is so hard and muscular, in this is extremely lax and soft, capable of great distension ; and, what is remarkable, is covered with a growth of fine down or hair, of a light fawn colour. It is difficult to ascertain the particular purpose which nature intends by this excrescence ; perhaps it may serve to shield the tender parts from the irritating effects produced by the hairs of certain caterpillars, some of which are said to be almost equal to the sting of a nettle." The same has also been said, first probably by some com- piler who had read Wilson's article and who thought he might safely enough infer it from analogy, of the stomach of the European cnckoo, but the writer of this has dissected several, and never observed any thing of the kind. The cuckoo's stomach is, how- ever, lax and membranous, like that of the American bird. Black billed Coccyzus(C.erythrophlhalmm'). "This species," according to Wilson, " is nearly as numerous as the former, * * * its peculiar markings, how- ever, and some of its habits, sufficiently characterise it as a distinct species. Its general colour above is nearly that of the former, inclining more to a pale ash on the cheeks and front; it is about an inch less in length ; the tail is of a uniform dark silky drab, except at the tip, where each feather is marked with a spot of white, bordered with a slight touch of dull black ; the bill is wholly black, and much smaller than that of the preceding, and it wants the bright cinnamon on the Avings. But what constitutes its most distinguishing trait is a hare wrinkled skin of a deep red colour, that surrounds the eye," whence the species have, though not very accurately, been named erythropkthalmits, or red-eyed. " The black-billed Coccyzus is particularly fond of the sides of creeks, feeding on small shell-fish, snails, &c. I have also found broken pieces of oyster-shell in its gizzard, which, like that of the other, is covered with fine downy hair." Audubon found in the stomach of this bird, in addition to shells and water insects, "a small black frog, which appears after a summer shower." The sustenance, therefore, of this species is rather anomalous, and peculiar for a member of the cuckoo family. " Its nest is commonly built in a cedar, much in the same manner and of nearly the same materials as that of the other ; but the eggs are smaller, usually four or five in number, and of a rather deeper greenish blue." There is nothing known of the peculiar habits of the other species of this division, so it would be here little interesting to detail their colours and propor- tions. A notice of other birds allied to the cuckoo will be found in the articles LEPTOSOMUS, INDICATOR, and PHOSNICOPTERUS. CUCKOO F L O W E R - C U C U L L I A. r CUCKOO FLOWER is the Lychnis _ LinncEus, a common British plant found in moist meadows. It belongs to the tenth class and fifth order of the sexual system, and to the natural order Caryophyllca:. The Cardamine pratcnsis, another com- mon plant in moist meadows, is also called cuckoo flower, but the plants are in no way connected except in habitat. CUCUJID.E (Stephens; PLATYSOMA, Latreille). A family of coleopterous insects of small extent and iignivorous habits, placed between the Xylophaga and the Longicorncs, having the tarsal joints entire and not bilobed; the antennae are of an equal thickness, or slender at the tips ; in some species, however, the three terminal joints are incrassated ; the jaws are robust and exserted, and the body very much depressed and of an oblong form. These insects are of small size, and are found beneath. the bark of trees, where also the larva? reside. Their situation appears to be much nearer to some of the Necrophagous Pentamera, such as Ips, than to the Longicorn Tctramcra. The genera are Cuciijns, Dendrophagus and Ulcoiota, to which Mr. Stephens has added that of Trogosita of Fabricius. The typical genus has the antenna? shorter than the body, with the basal joint shorter than the head. There are several British species, but their synonymy is very confused. The males of Ulcoiota Jlavipcs have the mandibles armed with a remarkable curved horn. CUCULIN/E (Latreille). A subdivision of the insects composing the family Apidte, or true long- tongued bees, distinguished by the non-possession of organs for the gathering of pollen, and consequently compelled to resort to the ne?ts of other bees for the deposition of their ecgs. Hence, like the cuckoo, they may be regarded as a kind of parasite. The iarva? of all bees are nourished by a paste formed of pollen and honey, but in nearly one-third of the genera of th, d, and pi. 41, fie:. 4. d. C U L L U M I A — C U P A N I A. see), ' SjrfuEromias, and Corclhra, Meigcn. The latter genus is distinguished from C/iironomns, by having the antennoB composed of fourteen oval joints in both sexes, the terminal ones being but little different from those at the base of these organs. The wings, when at rest, are laid horizontally upon the back. The type of the genus (which comprises but very few species; is the Tipula citlicifurmis of De Geer, by whom the history of this species has been traced through its different stages. Reaumur likewise found the larvs of another straw-coloured species (C. jrfumi- cornw, in July and August, in standing water. Its body is crystalline and transparent, long, nearly cylindric, and rather thickened at its anterior part ; the head is furnished in front with two recurved jointed hooks ; and the tail is armed beneath with an oval plunied apparatus, for swimming or respiration, and at the tip with two hooks. The nearer this crystalline larva (which is a beautiful microscopic object) is to its transformation, the more distinctly four kidney-shaped bodies are perceived, two in the front part of the second, and two in the ninth seg- ments of the body. It has been stated, in the Insect Transformations, that the latter perhaps serve to inclose the taii-.ins of the pupa, and the former the horns of the pupa, which again encase the antennae of the gnat (midge), both which statements appear to us quite untenable ; because the tail-fins of the pupa, being attached to its terminal segment, would neces- sarily be covered by the terminal segment of the iarva), whilst the antennae are laid along the breast, the " antennae cases," as they are miscalled, arising from the thorax. It is more probable that the arr- terior pair of these bodies may, as De Geer con- jectures (vol. vi. ]>. 39j), be air-reservoirs, which, when the insect assumes the pupa state, become external, and are transformed into the horns in front of its body. Moreover, analogy induces us to adopt this opinion, as the same organs are found employed in respiration in the pupa of the gnat. Like most larvae, the one which we are now describing sheds its skin. In like manner, it seems clour, from the statement of Reaumur, that the skin is also cast on assuming the pupa state, as he found exuviae at the bottom of the glass in which he kept them. The pupa is oblong, with the thorax bulging out, and having (wo small horns placed upon the front of the back ; the head is closely applied to the front of the breast, with the antennae lying behind the eyi-s, and the legs placed along the breast, enclosed in short cases. The tail is long, and gradually tapering to the tip, which is furnished with two elliptic-shaped plates employed in swimming. In this state it is very active, jerking about with great agility, especially when the time for assuming the perfect state ap- proaches. It, however, usually keeps close to the surface of the water, so as to be able to project the thoracic horns above it, so that they are exposed to the air, an eviden-t proof of their being employed as organs of respiration. The insect remains in this state ten or twelve days, when it assumes the perfect winded state. CULLUMIA (R. Brown). A genus of orna- mental shrubs from the Cape of Good Hope, belong- ing to the order Composites. Generic characters : anthodium of one leaf, thickly set with scales. Re- ceptacle favose, seeds smooth ; pappus none. This plant is curious, and easily kept and propagated in green-houses under ordinary management. CULTRIROSTRA, a sub-order of stilt birds, characterised by the bill being long, strong, and knife- shaped. It includes the cranes, storks, herons, and some of the allied g-enera. See BIRD. CUMMINGIA^ (U. Don). An elegant, bulbous- stemmed plant, introduced into this country from Chili. Linnaean class and order Hcxandria Mono- gynia, and natural order AsphodcletjE. Generic cha- racter : calyx, bell-shaped, six-cleft, nearly regular, spreading ; stamens inserted in the base of the corolla ; filaments very short, united in a ring ; an- thers forming a cone, with cleft processes at top ; style awl-shaped ; capsule three-celled, three-valved, with many seeds. This is the Conanthera campamdata of Ruiz and Pavon, and of several other authors. Three species are already known, and they succeed when managed like other tender bulbs, that is, planted in a frame or pit, or on a warm border ; the bulbs to be taken up before winter, and planted again in February. They are increased by seeds and offsets. CUMINIUM (Limucus). An odoriferous plant, cultivated for its peculiar qualities as seasoning in cookery, and as a medicine. It belongs to the natural order UmbellifcrcB. In this country it only requires sowing in the open ground, with other an- nual herbs. CUNNINGHAMIA (R. Brown). A fine orna- mental forest tree, introduced from China, It belongs to the class Moncecia of Linnaeus, and to the natural order Conifercs. This is the Pinus Innceolata of Lam- bert, and the Sells jaculifolia of Salisbury. CUNONIACE^E. A natural order" of dicotyle- donous plants, containing eight genera and forty-four known species. It is closely allied to Saxifrages, and by many botanists is considered merely a section of that order. It differs, however, in its shrubby habit and its remarkable interpetiolar stipules. It bears also an affinity to Baueraccce, from which it is distin- guished by its definite stamens and the presence of stipules. The characters of the order are : calyx four or five- cleft, half superior ; petals four or five, occasionally- wanting ; stamens eight to ten, perigynous and defi- nite ; ovary two-celled, the cells having two or many seeds ; styles one or two ; fruit two-celled, capsular or indehiscent ; embryo in the axis of fleshy albumen. The plants belonging to the order are trees or shrubs with opposite, compound, or simple leaves, interpe- tiolary stipules, and white or red Bowers. They are found at the Cape of Good Hope, in South America, the East and West Indies, and New Holland. Little is known in regard to their properties. The chief genera of the order are : Cimonia, Wcinmannia, Callicoma, Dicterica, Ccratopctalum, and Arnoldia. Of the genus Weinmannia, there are thirty-one known species, most of which possess astringent qua- lities : one of the species is used in Peru for tanning leather, and its bark is employed to adulterate Peru- vian bark. CUPANIA (Linnaeus). A genus of lofty tropi- cal trees, belonging to the eighth class and first order of the sexual system, and to the natural order Sapin- dacecE. Generic character : calyx of five sepals ; petals cupped or flattish ; filaments awl-shaped ; sometimes long, but frequently very short ; anthers incumbent ; style trifid ; stigma obtuse ; capsule leathery, and three-celled, three-valved ; cells one or two seeded, seeds winged. This tree is cultivated 206 CUPHEA— CUPULIFER^E. in our stoves, is grown in loam and moor-earth, and is propagated by ripened cuttings struck in sand, and a Httle heat. CUPHEA (R. Brown). A genus of greenhouse, annuals, and hothouse under-shrubs, natives of the West Indies. Linnaean class and order Dodecan- dria Monogynia, and natural order Salicarice. Generic character : calyx tubular, swollen at the base ; limb from six to twelve-toothed, the upper tooth broad ; petals six, inserted in the calyx ; stamens from ten to fourteen, fixed to the throat of the calyx, unequal ; anthers two-celled ; style filiform ; stigma simple or two-lobed, bottom of the ovarium glandular ; capsule covered by the calyx, one-celled ; seeds like lentils. The annual species may be sown in the open ground, like other annuals ; and the biennial sorts should be raised on heat, put into pots, and kept in the green- house or stove. CUPRESSUS (Linnaeus). A genus ofornamental evergreen trees, commonly called cypress. They belong to the twenty-first class of Linnaeus, and to the natural order Coniferce. A few of this genus are kept and propagated and managed like other green- house plants. The hardy sorts are raised from seeds, and nursed in pots till fit to be planted on lawns or other parts of ornamented ground. When young they are tender, and liable to be killed by severe frost ; but in favourable situations, as in the south of England, and in all warmer countries, they gain a considerable height, and are very conspicuous trees. They were anciently, as well as at present, in south- eastern Europe, chosen as memorials of the dead ; and still are the principal ornaments of cemeteries in Greece and over all the Ottoman empire. CUPULIFERjE— The oak family. A natural order of dicotyledonous plants, containing five or six genera, and numerous important species. It is allied to the willow and birch families, but is distinguished from the former by the veining of its leaves, and from the latter by the presence of a calyx. It bears also an affinity to UrticefE, but differs in its many-celled ovary, pendulous ovules, and superior calyx. By many .botanists this order is considered merely as a section of Amentacece. The name Cupulifereee is derived from the peculiar husk, or cup (cupule), in which the fruit is enclosed. The essential characters are : flowers unisexual ; male ones amentaceous, with from five to twenty stamens, which are generally distinct, and are inserted into the base of the scales, or perianth ; female ones aggregate, or amentaceous ; ovaries crowned by the rudiments of a superior calyx, seated within a coria- ceous involucre, variously formed, and with several cells and ovules, the greater number of which are abortive ; ovules twin, or solitary, pendulous ; stigmas several, nearly sessile, distinct ; fruit, a horny, or coriaceous, one-celled nut, more or less enclosed in the enlarged involucre (cupule) ; seeds solitary, two to three, pendulous ; embryo large, with plano-convex, fleshy cotyledons, and a minute superior radicle. The plants belonging to this order are trees or shrubs, having alternate simple stipulate leaves, with veins proceeding straight from the midrib to the margin. They inhabit chiefly the temperate parts of the northern hemisphere, and form extensive forests both in the old and new world. They are common in Europe, Asia, and North America, and they are also found in some parts of South America, and in the northern parts of Africa. They are said to be totally unknown at the Cape of Good Hope. Some of the species grow on the high lands of tropical regions. The order furnishes many trees which are highly valued on account of their timber. Its medicinal properties in general may be said to be astringent and tonic, and it includes some plants which are used in the arts, and others which are employed as articles of materia medica. The chief genera are, Quercus, or oak ; Castanea, or chestnut ; Fagus, or beech ; and Corylus, or hazel nut. The genus Quercus, or oak, belongs to the class Monaeria, order Polyandria of the Linnaean system, and is well known as supplying many important species of forest trees. According to Michaux, there are at least forty-four species of the genus in America, confined entirely to the northern hemisphwe, ex- tending from the 48th to the 20th degree of latitude ; while in the old world there are upwards of thirty species, which grow both in the northern and southern parts, from the 60th degree of north latitude. The species have been divided by him into separate sections, according as the fructification is annual or biennial ; and the different forms of the leaves have furnished him with a means of further subdivision. Of all the species, the Quercus robur, or pedunculata, of some foreign authors, the common British oak demands our first attention, whether we consider the dignity of its stature, or the variety of uses to which it is applied. It is the king of our forests, excelling all other trees in the beauty of its growth, the thickness of its trunk, and the hardness and solidity of its wood. It constitutes the greatest part of the European forests, extending from the 60th to the 35th degree of latitude. It is indigenous in our island, and grows well in almost any soil, and even in the most exposed situations. It delights in rich deep earth, but the finest grained timber is said to be produced in sandy soils. It is found both in forests and hedgerows, but succeeds best in the former. The flowers appear in spring, but the exact time at which the leaves and flowers expand varies much, accord- ing to the situation and soil in which the tree grows. Sometimes we notice one oak in full leaf, and another, not far from it, without any such appearance, owing to the coldness or barrenness of the soil in which it has been planted. The leaves are generally put forth at a later period than those of other trees, but they continue longer green. The oak is usually raised from its seeds, which are ripened in October, and well known by the name of acorns. These may be either sown at once in the place where the oaks are to remain, or in a nursery, and the young trees subsequently planted out. They are sown in the spring or autumn, in loamy well prepared soil, and the young plants generally appear above ground in the course of six weeks. If reared in a nursery, they may be planted out in the course of two years, and considerable care is necessary in keeping the ground clean, and free from weeds. The plants, in the first instance, are set in rows, four feet asunder, and two feet distant in the rows, and after twelve or fourteen years, every second plant is taken out, and sold for hoops, or small poles. After seven or eight years more, another thinning may be prac- tised, the" strongest and most vigorous trees being left to form timber at the distance of twenty or thirty feet from each 'Hher. The plantations should be CUPULIFER^:. 207 sheltered by means of Scotch fir, or other hardy quick-growing trees. On the judicious thinning and clearing of a young wood, as well as protecting it from the severity of the climate, depends much of a planter's success and profit. The oak might be culti- vated very profitably on many waste lands situated near rivers or navigable canals. When the acorns are sown in a field, and the trees allowed to grow naturally, we secure the best timber for the use of the carpenter and ship-builder, and in a much shorter time than if the plants are first raised in a nursery, and then transplanted. The oak attains a great age, and is said not to reach maturity till it is one hundred years old. Some of the aboriginal oaks of this country have been known to exist for a thousand years. The oak against which the arrow of Walter Tyrrel glanced, before it killed William Rufus, was in existence less than a century ago ; and there is still seen at Torwood, in Stirlingshire, the oak under which the famous Wallace convened his followers. The oak sumeumcs ^-quires the height of 100 feet, more especially when planted in woods. Its trunk also attains a great degree of thickness. The trunk of an oak growing in 1764 iu Broomfield wood, Shropshire, was sixty-eight feet in circumference and twenty-three feet in length. The tree was estimated to contain 1455 feet of thick timber. The circum- ference of the green dale oak, near Welbeck, at eleven feet from the ground, was thirty-eight feet, and one growing near Wetherly, in Yorkshire, mea- sured seventy-eight feet close to the ground. Dr. Thomson mentions that an oak was felled at Whitby Park, Shropshire, in 1697, which was nine feet in diameter without the bark ; its branches spread 144 feet, and twenty-eight tons of timber were contained in the body of the tree. Dr. Plott mentions an oak, at Norbury, which was forty-five feet in circumference, and when it was felled and lying on the ground, a horseman on one side of the trunk was completely concealed from one on the other side. While the tree thus attains a hreat height and thickness, it also sends its roots deeply into the ground, and is thus enabled to resist the shocks of tempests and the war of elements. As o'er the aerial Alps, sublimely spread Some aged oak uprears his reverend head, This way and that the furious tempests blow, To lay the monarch of the mountain low ; Th' imperial plant, though nodding: at the sound, Though all his scattered honours strew the ground, Safe in his strength, and seated on the rock, In naked majesty defies the shock ; High as the head shoots towering to the skies, So deep the root in earth's foundation lies. The oak is a very valuable forest tree, and is much cultivated on account of the timber and bark which it furnishes. Houses and ships, cities and navies, are formed of it. To it we are indebted not only for our maritime glory and commercial prosperity, but also for many of the ordinary comforts of life. From a small acorn see the oak arise, Supremely tall and towering to the skies ! Queen of the groves, her stately head she rears, Her bulk increasing with increasing years! Now moves in pomp majestic o'er the deep, While in her womb Britannia's thunders sleep ; With fame and conquest graces Albion's shore, And guards the island where she grew before. The oak was held sacred by the Greeks and Romans as well as the ancient Britons. By the Romans it was dedicated to Jupiter, and in former times Druidical ceremonies were frequently performed under its shade. The fruit of the oak was used in the early ages of the world as an article of food, and the failure of the acorn crop was considered as a cause of famine. Now-a-days acorns are given as food to hogs, squirrels, and the larger gallinaceous birds, and are said to have a great effect in fattening them. The root of the oak is beautifully grained, and is employed for many useful and ornamental purposes. All the parts of the oak are astringent, but the bark possesses this property in a remarkable degree, and is on this account used officinally. Oak bark is covered with a bluish-grey epidermis, and within is of a red colour. It is peeled in spring, when it is more astringent than in the later part of the season. Its astringency is owing to the presence of gallic acid and tannin, which exist in great quantity in the inner part of the bark. As a powerful astrin- gent, it is given internally in powder, in doses of from two to six drachms. It may be used as a substitute for cinchona bark in the cure of ague, and has been ad- ministered to stop internal haemorrhages and bleed- ing from the nose and mouth. The decoction of the bark is used as a gargle in relaxed sore throats, and as a lotion to indolent ulcers. An extract of the bark is also prepared tor medicinal use. The use of the bark in tanning leather is familiar to all, and its employment in the construction of hot- beds is also well known. The saw-dust of the oak is used in dyeing all the varieties of drab and the differ- ent shades of brown. An infusion of the bark with a small quantity of sulphate of iron is employed by com- mon people to dye woollen stuffs of a purplish colour. Acorns and their cups when roasted are adminis- tered either in the form of powder or infusion in cases of bowel complaint and passive haemorrhages. The only other British species of the genus is Quercus sessiliflora. The specific name is apt to mis- lead, inasmuch as the flowers in both species are ses- sile. In the common oak, however, the catkin is on a long footstalk, while in the present species it is nearly sessile. The timber of this species is generally considered inferior to that of the Quercus robur. Quercus suber, the cork tree, is a tree about forty feet high, which grows in the south of France, in Spain, Portugal, Italy, and the north of Africa, be- tween the thirty-fifth and forty-fourth degrees of lati- tude. Its leaves continue green till the middle of May, when they generally fall just before the new leaves appear. It yields oval acorns like those of the common oak, which are eaten by hogs with avidity. Its timber is heavy, hard, and compact, but not very durable. The tree is chiefly valuable on account of its bark, the external layer of which fur- nishes the light, elastic, and impermeable substance called Cork, which is applied to so many important uses. The bark is taken off every eight or ten years, and the trees will often live for 150 years, even though the process of removing their bark is repeated regularly. When young, the tree does not yield good cork, and the two first peelings are in general not fit for use. It is only when the trees are about forty years old that the bark becomes valuable. The stripping of the bark takes place in the months of July and August. Two incisions are made parallel to each other along the whole length of the tree, and then two others are made transversely at the extre- mities. The outer bark is then removed, care being £08 CUPUL1FER.E. taken not to injure the inner cortical layer, otherwise iio new bark would be produced. After being taken olF, the bark is flattened by exposing its convex sur- face to heat and pressure. It is also charred on both sides, so as to close the transverse pores before being sold. The carbonised surfaces are seen in bungs and taps, but not in ordinary corks which are cut length- wise. The bark gathered in France has been esti- mated as sufficient to form 1 19,000,000 or 120,000,000 of corks eighteen lines long. Cork was used by the Greeks for sandals, and is occasionally employed now-a-days for lining the soles of shoes. It is also employed to form surgical instru- ments and apparatus, and is essential to the cabinet of the entomologist. The charcoal got from it, when mixed with lard, has been recommended in piles. It contains a pecu- liar principle called Subcrin, and an acid called Suberic acid. Quercus tinctoria is an American tree which attains the height of eighty or ninety feet with a diameter of four or five feet." It supplies useful timber, and its bark is used for tanning leather. The cellular part of the bark furnishes quercitron, a substance used for dyeing wool and silk of a yellow colour. It is said to be superior to woad. The decoction of quercitron has a brownish yellow colour, which is rendered deeper by alkalies. Quercus cocci/era, the kermes oak, grows plentifully in Spain, Provence, Languedoc, and along the coast of the Mediterranean. It is a tree of small growth, being in general not more than twelve feet high. Its acorns are smaller than those of the 'common oak. From this tree is gathered the vegetable kermes, an insect with which the ancients used to dye their gar- ments of a beautiful pink colour. Since the discovery of America, the coccus cacti, or cochineal insect, has supplied the place of the kermes. Kermes is met with in commerce in the form of little red globular grains torn on the side where the animal adhered to the leaves or young branches of the oak. According to analysis it consists of yellow fatty matter, red colouring matter analogous to car- mine ; coccine, a peculiar animal matter, and various phosphates and muriates. The colour obtained from the kermes is said to be more fixed than that got from the Mexican insect. Quercus esculus, cut-leaved Italian oak, is the small oak or phagus of the Greeks, and the Esculiis of Pliny. It is a native of Spain and Italy, and was used by the Romans to form their civic crowns. Its acorns are sweet, and are frequently eaten by the poor in the South of France, who, in times of scarcity, grind them and make bread with the flour. Quercus rubra, red oak, is a native of Virginia and other parts of North America. It extends far north, and grows to the height of eighty feet. It yields large acorns, which are eaten by wild animals, as well as by horses, cows and hogs. Its bark is employed for tanning, but its wood is not much used in building. Quercus alba. White oak, so called on account of the whiteness of its bark ; is a native of North Ame- rica, where it reaches the height of seventy or eighty feet, with a diameter of six or seven feet. Its wood is considered in America preferable to any other sort for building, on account of its strength and durability. The wooden bridge which joins Cambridge and Bos- ton, and which is nearly 3000 feet long, is supported by posts of white oak from fourteen to fifty feet long. Its bark contains a considerable quantity of tannin, and an infusion of it has been known to cure ague. Its acorns are large, oval, and sweet. Quercus virens. Live oak, found in Carolina and Virginia ; yields small acorns, which are eaten by the Indians, and are used by them to furnish a sort of oil. The acorns of Quercus ilex, evergreen oak, are mild and nutritive, and serve for food. The acorns of Quercus cegilops, a native of Spain and the Levant, where it is called Velonia, are imported as a dye-stuft'. Many other species of oak might be noticed, such as black oak, scarlet oak, willow oak, chestnut oak, laurel oak, dwarf oak, water oak, &c., most of which are cultivated either on account of their wood or bark ; but it appears unnecessary to dwell longer on the subject, inasmuch as the properties of the oak tribe have been already sufficiently illustrated by the ex- amples which have been adduced. Before, however, proceeding to treat of another genus, we shall make a few remarks on a disease to which the oak is sub- ject, in consequence of the attacks of insects. The leaves, flowers, and fruit of almost all vegeta- bles are liable to be attacked by the insect tribe ; The flowery leaf Wants not its soft inhabitant. Secure Within its winding citadel the stove Holds multitudes. But chief the forest boughs That dance unnumher'd to the playful breeze, The downy orchard and the melting pulp Of mellow fruit, the nameless nations feed Of evanescent insects. In some cases their attack is followed by the production of a peculiar substance, which is turned to useful account in a medical or economical point of view, and of this we have an excellent, illustration in the genus now under consideration. Upon the leaves of all the species of oak there are tound globular bodies, to which the name of galls, or gall-nuts, has been given. They are produced by various small four- winged insects, denominated Cynips quercusfolu, or Diplolepis gallce tinctorice, £c. The adult female insect is furnished with a long slender spiral sting, with which it punctures the stalk of the oak-leaf, and at the same time deposits a minute egg, and probably some irritating fluid. In consequence of the irritation, which is produced by this wound, the sap is deter- mined to the part, and the extravasated juice flowing around the egg soon forms a soft excrescence, which serves both for the shelter and food of the young insect. The tumour increases very rapidly, until a perfect gall is formed. The larva afterwards issues from the egg, assumes the pupa state, and then escapes as the perfect fly, by perforating the walls of the chamber in which it is inclosed. The best galls are those which are gathered before the insect has escaped, and are denominated black, blue, or green galls, on account of their colours. There is of course no perforation in them, and on opening them we find perfect specimens of the fly. Those galls, on the contrary, which are collected after the fly has escaped, are called white galls, and are not so much esteemed, containing less astringent principle than the entire galls in the proportion of two to three. The oak on which the finest galls are found is described by Olivier, in his Travels in the Ottoman Empire, as the Quercus infectoria, a small tree grow- ing in Asia Minor. The galls are collected by the poorer inhabitants, and are exported from Smyrna, Aleppo, and vari as parts of the Levant. C U P U L I F E R JE. 209 Oak-galls have a round globular form, and vary in size from that of a pea to that of a hazel nut. They contain, according to Sir Humphrey Davy, tannin, gallic acid, mucilage, saline, and earthy matter. A remarkable difference exists between the chemical properties of the oak-bark and nut-galls, the latter precipitating tartar emetic and infusion of cinchona, which are not acted on by the former. Water dissolves all the active matter of galls. The solution for medicinal use ought to be prepared by simply infusing the galls in distilled water at the temperature of about 180°. In this way we procure all the gallic acid and tannin in solution, without a mixture of extractive, £e. Galls are used in medicine, both externally and internally, as astringents. They are prescribed in the form of powder, infusion, tincture, or ointment. When adn 'ully, they are often mixed with aromatics, so as to render them more agreeable to the stomach. In this way they are used in India for the cure of intermittent fevers. The infusion is employed as a gargle for relaxed sore throats, and as an astringent lotion for ulcers, while the gall ointment is applied as a remedy for piles. The powder, in doses of ten or twenty grains, is perhaps the best form of administering this medicine. Some prepara- tions made from galls are used as styptics, to stop bleeding from wounds, leech-bites, &c. Galls are also employed in dyeing, and in the pre- paration of common ink. In allusion to the latter circumstance, it has been well remarked — " How infinitely we are indebted to this little creature (the gall-fly), which at once enables us to converse with our absent friends and connexions, be their distance from us ever so great, and supplies the means by which, to use the poet's language, we can Give to airy nothing A local habitation and a name ! When any salt of iron is added to an infusion of galls, a black colour is immediately produced, and it is upon this principle that ink is manufactured, this valuable liquid being merely a decoction of galls, sulphate of iron or green vitriol, and logwood, with a little gum, which is added to give it a consistence. The galls formed on the common oak, qucrcus ccmx, and other species, are small, and smooth and reddish, and arc riot applied to use. The next cupuliferous genus to which we shall allude is Castanea, chestnut. Castanea vulgaris, or vcscn, formerly Fagus castanea, the sweet, or Spanish chestnut, is a beautiful tree, the trunk of which often acquires a great size. It is stately and majestic, rivalling the oak in magnitude and duration. It is common both in this country and on the continent. Its flowers appear in long spikes about the month of June, and its fruit, which is enveloped in a husk defended by prickles, is ripened in September or October. The nuts which it yields are familiar to every one under the name of chestnuts. The bark of the tree is remarkable for its deep and wide clefts, which seem to have furnished ideas for some of the ornaments in Gothic archi- tecture. The chestnut is not so picturesque as the oak, but it is sometimes introduced into the paintings of the old masters, more particularly those of Salvator Rosa. Chestnut trees are remarkable for the age and size which they sometimes attain. At Tortworth, in NAT. HIST. — VOL. II. Gloucestershire, a chestnut tree grew in 1766, which was said to be upwards of one thousand years old. It was fifty-two feet in circumference, and was known to have served for a boundary-mark in the reign of King John, at which time it was five hundred years old. On Mount ^Etna, in what is denominated the third, or woody region, there is a gigantic chestnut tree, known by the name of Castagno de cento cavalli, or chestnut of a hundred horse, because it was said to be capable of sheltering one hundred horses under its boughs, It is believed to be some thousand years old. It seems to consist of five large, and two small trunks, which, in all probability, formed only- one originally, inasmuch as there is no bark on the inside of the trunks, nor on the sides that are opposite to one another. The largest trunk is thirty-eight feet in circumference, and the whole five taken toge- ther measure one hundred and ninety-six feet round. Although the interior is entirely decayed, and there is a wide public road through it, still the tree bears foliage, and even produces fruit. A hut is built within the trunk for the habitation of those who are engaged gathering and preserving the fruit. Several other large chestnut trees grow on the sides of Mount -ZEtna. Chestnut wood was formerly in great repute for building. Evelyn mentions, that most of the ancient houses in London were built of it, and that a large forest of chestnuts existed in old times in the neigh- bourhood of that city. The church of St. Nicholas, at Great Yarmouth, erected in the reign of William Rufus, is roofed with chestnut. The wood serves also for various economical purposes. It is used for palisades, and props for vines and hops, as well as for water-works. Pipes bored of it, and lying constantly under ground, are said to be very durable. The Italians make casks and tuns for wine from this wood. Chestnuts are mentioned by Virgil and Pliny as excellent articles of food. They are constantly used as such in the south of Europe at this day. Dr. Hooker states, that in some parts of France he has had them served up for breakfast boiled in milk. They are farinaceous, and when boiled have a sweet and agreeable taste. They consist of fecula, gluten, very analogous to that found in grasses, and a saccha- rine principle. They are used for whitening linen cloth, and for making starch. They are much relished by deer and swine. There are several varieties of chestnut in cultiva- tion. One of these, with striped leaves, is considered very ornamental. The trees are raised from the nuts, which are carefully selected, and placed in seed- beds in the month of February. In these they are allowed to remain for two years, and are then planted in rows, two or three feet apart, and a foot and a half distant in the rows. In the course of four or five years they may be planted out. This treatment is adopted when it is wished to produce fruit in abun- dance. If, however, the trees are intended for timber, they ought to remain in the spot where the seeds were originally sown, being merely thinned out, and kept free from weeds. Some, however, disap- prove of this method, and think transplanting the best mode of rearing the tree, whether fruit or timber be desired. The chestnut succeeds well in almost any soil, but thrives best in rich loamy land. Castanea pumila, the Chinquapin, or dwarf Virgi- nian chestnut, is another species common in the O 210 CURASSOW. American wood?, and attains a height of twelve or fourteen feet. It is a hardy tree, and produces abundance of nuts. It is sometimes cultivated in Britain. The next genus for consideration is Fergus, or beech. Fagus sylvatica, the common beech-tree, is abundant in forests in the south of England, but is rarely found wild in Scotland. It is a handsome and •valuable forest tree, putting forth green leaves, many of which, more especially when the tree has been clipped, remain during the winter, and assume a brown colour — The red leaf Seared in autumn's breath, yet wearing well A garb to hail the coming winter in. The leaves, after they fall, do not readily decay, and are used by the country people in France in place of straw for their beds. The tree is either planted in woods or hedgerows, and sometimes attains a considerable height. Beech woods are peculiarly dry, and agreeable for walking, and are eagerly sought by the botanist, on account of the many rare orchideous plants which they contain. The leaves of the beech appear in April, and the flowers are produced in May. They are succeeded by an angular fruit, the size of a filbert, commonly called beech-mast, which is ripened in autumn. There are two varieties of beech, the one with dark red, the other with cut leaves. The wood of the beech is hard and brittle, and is employed by cabinet-makers, turners, and wheel- wrights. Carpenters' planes are made of it, and when split into thin layers, it forms scabbards for swords. The ancient shepherds carved their love verses on the green bark of the tree, and they used the wood for the manufacture of bowls. No wars did men molest, When only beechen bowls were in request. Beech nuts are sweet and agreeable, and have been used for food. When dried and powdered, they have been made into wholesome bread. They enabled the inhabitants of the island of Chios to endure a me- morable siege. When roasted, they are sometimes used as a substitute for coffee. By expression, they yield a thick oil, which may be kept many years without becoming rancid. This oil is used for seasoning in some parts of France ; and in Silesia the poor people make use of it in place of butter. Swine are driven in autumn into beech forests to feed upon the mast. The beech tree is propagated from seeds, and is treated in the same way as the oak and chest- nut. It delights in a chalky and stony soil, and, when fully grown, affords an agreeable shade, as is beautifully noticed by Virgil in his First Eclogue. (For further particulars iu regard to the cultivation of this tree, see article BEECH.) Another genus, which is sometimes included under this order, is Corylus, or hazel. Corylus ave/lana, common hazel nut, grows abundantly in hedges and copses in all parts of Britain. It flowers early in spring, and ripens its fruit in September. The nuts, which are known by the name of filberts, are sweet, agreeable, and nutritive, and are common at our tables. Of the several varieties, the frizzled filbert is the best. The nuts contain a thick fixed oil, and are sometimes made into emulsions. The wood is used for various domestic and agricultural purposes. It forms good charcoal for drawing The young forked twigs of the tree constitute the celebrated divining rod, which, in the ancient days of superstition, was employed to indicate the part of the soil in which metals and springs of water existed. The hazel is generally raised from seed, and, in order to produce fruit abundantly, it is regularly pruned, and not allowed to attain a great height. The name hazel-nut is derived from two Anglo-Saxon words, hascl, a cap, and knutu, a nut. (We have already given a short notice of this tree under the article BETULINE^, in which order it is included by some authors.) The members of this family bear a very strong resemblance to each other, both in their botanical characters and medical properties. In all of them the bark is bitter and astringent, and is used for dye- ing, tanning, or for medical purposes. The wood is, in general, employed as a durable timber for building. While, in a few instances, the fruit is bitter and disagreeable, in the greater number it is farinaceous, and frequently contains an oily matter used in do- mestic economy. There are no poisonous plants in this family. CURASSOW, or HOCCO— Crax. A genus of gallinaceous birds belonging to the family ALEC- TORiDjE, under which some account of the characters of that family, and a list of the genera which compose it, will be found. The generic characters of the present genus are : the bill strong, of mean length, compressed, higher than broad at the base ; the upper mandible elevated, arched, curved from its origin, which is enveloped with a membrane ; nostrils basal, lateral, and partly closed with membrane ; head ornamented with a crest composed of feathers which are erect, but recurved at their points ; tarsi long and without any spur ; three toes to the front united at their bases by a small membrane, and one toe to the rear which reaches the ground in walking ; wings short, concave, and rounded ; the sixth quill being the longest ; tail composed of twelve large feathers. The AlectondcB occupy the same place in the natu- ral history of tropical America, which the Gallinae do in that of tropical Asia ; and among them the genus Crax answers to the genus gallus, or common domestic poultry. They are found only in the rich forests of South America, and are more equatorial in their habits than the turkeys, though in their localities the two genera border upon each other, and, of course, to a certain extent occupy the confines of each other's ground. Like the jungle fowl of the east, the Curas- sows (Hoccos is the preferable name, for Curassow is the trivial name of -only one variety, and it is not a very happy one, being derived from the island of Cura9oa,in which we believe the birds are not found) are all perchers ; though they all seek their food upon the ground. Like these, too, they are very im- patient of rain, and their plumage is soon wetted ; in fact there is in their whole economy a very great resemblance to the fowl of the east. That the principal ground-feeding birds of the two most fertile regions of the world, which have nearly the same latitude, but are almost the antipodes of each other in point of longitude, should correspond so nearly in their general habits and economy, is an important point in natural history ; because it esta- blishes the connection which there is between the region and the inhabitants. It also lets us see wny the gallinaceous birds of those rich tropical countries C U R A S S O W. 211 which have strongly marked varieties of seasons, J should be different from those of more temperate ' climates, and also of the more elevated and exposed places of the same climates. The gallinaceous birds which are indigenous to the latter situations, gene- rally squat and nestle on the ground during the night as well as in nesting time ; while those of the tropical forests are invariably perchcrs, have their wings short, broad, hollow, and rounded at the extremities, and their tails large and strong ; so that, though they are not adapted for long flight, there are no birds which get more quickly or more easily on the wing, or fly more nearly in the perpendicular. This is necessary, in consequence of the greater abundance of enemies which these birds have on the ground than the birds of open places ; and it is also necessary that they should perch, because during the rains the ground is often laid under water for several days. In a wild state the curassows inhabit the most remote places of the forests, carefully shunning the settlements of the colonists and the huts of the natives ; but though they are retired they are so far from being shy, that they fall an easy prey to the sportsman. There are, comparatively speaking, few birds of prey, in those close places, because there is no scope for their wings ; and therefore the usual safety of the curassow is gaining a branch. Thus when the sportsman comes before a pack of them, for they are sociable and live in considerable packs, he can shoot as many as he chooses. Like the corresponding races of the east, these birds seem to tell man in as plain language as nature can speak to him, that the phices which they inhabit were made for him to cultivate, and that they them- selves were made to live with him in a state of domes- tication. For, as soon as they are brought into the farm-yard, they become as confiding as they are timid when in a state of nature. They breed freely, have no disposition to wander, fatten well, and are very valu- able for the table, as well for the quality as the quan- tity of their flesh. When in a state of nature, they are not nearly so prolific as our domestic poultry, the esrgs in a hatch being only from four to six ; but we believe that in all the species there are two broods in the vear. There are, however, no animals, the ferti- lity "of which is so much affected by treatment as domestic birds, more especially poultry; and the number of eggs which a domestic hen will lay, even in the cold countries of Europe, is far greater than that which a wild hen of the very same species will lay in the jungles of South-eastern Asia. As house- hold poultry the present genus of birds are very successfully cultivated in South America ; but the attempts which have been made in Europe have not been so successful ; so that the birds are rarely seen except in single specimens in the collections ot exhi- bitors. What the cause of the failure may be is not very well known ; and it is rather singular that the cultivation of them should fail, while the pullet and pea-fowl of Asia, the Guinea-fowl of Africa, and the Turkey of America, all thrive so well. We believe, however, that there is something in the quickness of the transition ; for the Asiatic and African birds have come gradually, and were centuries on their march from their native localities to the west of Europe. The Turkey, though a much more northerly bird, was at first exceedingly difficult to rear ; and, we believe, that it is still the most tender chick in the poultry- yard ; and it is natural to suppose that if a bird of the comparatively temperate parts of America is thus delicate, one of the tropical parts must be much more so. It is also probable that as, hitherto at least, those who have visited the native abodes of these birds, have had neither taste nor skill in natural history, we may be ignorant of some circumstances which pre- vent this very valuable addition from being made to the birds of our farm-yards. The principal disease which these birds have displayed in the attempts to rear them in Europe, has been a sort of mortifica- tion in the feet ; but whether that has been caused by food or by locality has not been ascertained. In a state of nature, the birds are found on ground both hard and soft ; and they make their nests indiscrimi- nately on or under hillocks, in rifts of the rocks, and on the forks of thick branches of trees ; so that it is not easy to draw any conclusion as to what sort of locality would suit them best. Their history deserves to be studied much more carefully than it has been, and more with a view to domestic economy than to mere systematic natural history. There are several species, of the leading ones of which we shall give a list ; and as each of them has either two or three English names, or none, we shall give precedence to the systematic ones. CRAX CARUNCULATA — Wattled Curassow. This species is found in Brazil. It is a large bird, from two feet and a half to three feet in length. The upper part black with green reflections, the belly brownish, and the bill and feet black. The upper mandible of the bill is much elevated, and furnished at the base with a red membrane, which descends at each side a little below the under line of the lower mandible. It is from this that the bird gets its name. CRAX RUBRA — Red Curassow. This is also a ; Mexican species, if, indeed, it be a species, and not a mere variety of the other. It is nearly of the same size as the former, and almost the only difference between them is in colour. The upper parts and the breast are of a red colour, marked with darker spots of the same ; the head and neck are white, with a round black spot at the point of each feather ; the feathers which form the crest are white with black borders ; the under parts reddish ; and the bill and Kea dy assov. feet blackish ash. The young are mottied with white ! and black, and reddish, and have the black and the white on the head and neck reversed ; the feathers of the crest straight, and the quills margined with white. CRAX ALECTOR— Crested Curassow. This is the I species which is generally referred to as beine typical 02 C U R A T E L 1; A — C U II C U L I O N 1 D JE. of the genus; but it is not go any mure than the others ; and it is not more crested than they are, only its crest consists of feathers which are straight or nearly so, and broad at the tips, while in most of the other species those of the old birds are frizzled. We may remark, en passant, that the use of the crest to these birds seems to be to protect their eyes from the beams of a nearly vertical sun, which otherwise would prevent them from finding their food. The upper part of this species is streaked with white and reddish ; the breast, the belly, and the thighs are bright russet-red, crossed by black bands ; and the 'rest of the under parts entirely russet; the bill is whitish, and the feet reddish ash. These are the colours of the young birds before they attain their full size. The native birds are entirely black on the upper part, with iridiscent reflections ; pure white on the belly and under tail coverts ; but the colours are subject to variation. The bill and feet are blackish, the membrane of the bill and the naked space round the eyes blackish yellow. The size is rather less than the former species, though as domesticated there are great differences. CIIA.X GLOBICERA — Lumped Curassow. The dis- tinguishing character of this species is, a round protu- berant or nob on the upper mandible, immediately in front of the membrane. The upper part, and indeed the whole plumage with the exception of the belly, the lower tail coverts, and the tips of the wing coverts, all of which are pure white, is black, with various reflections. The membrane at the base of the bill yellow, the bill and feet black. The young have the prominence on the upper mandible very small, and streaked and mottled with black and white. Such are the leading species or varieties, as usually noticed by naturalists ; but it is doubtful whether these be any more than mere climatal varieties ; for we believe that they all breed readily with each other ; they are all nearly of the same size, and their manners are exactly similar. CURATELLA (Linnaeus). So called because its rough leaves are used in Guiana for polishing wood. The genus belongs to Polyandria Digynia, and to the natural order D'dleniacccE. Generic character : calyx of four or five sepals, persisting, sepals roundish, unequal ; petals rounded, hollow ; stamens inserted in the receptacle : filaments like threads ; anthers roundish, bursting inwardly. Style filiform ; stigmas headed ; capsules two, of two valves, hairy, one-seeded ; seeds oblong and naked. This plant is met with in our stoves ; is grown in sandy loam, and propagated by ripened cuttings. CURCULIGO (Gaertner). A genus of tropical herbs, belonging to Hejcandria Monogynia, and to the natural order Hypoxideec. Generic character : flowers bundled, somewhat spiked, and bracteate. Corollas with tube slender, to which the styles are united, limb regularly six-parted, spreading ; stamens fixed to the corolla ; filaments slender, erect ; anthers oblongly linear ; style cylindrical ; stigma a three- lobed head ; berry longish. These plants thrive in loam and moor earth, and are increased by suckers, which rise from the root. CURCULIONID.E (Leach). A very extensive family of coleopterous insects, belonging to the section Tetramsra, and sub-section Rhyncophora, being gene- rally known by the English name of .weevils, and corresponding, for the most part, with the Linnaean genus Curcidio. The frontal elongation of the head into a snout, or rostrum, at once enables us to dis- tinguish them from all other beetles. The Bruchidae. it is true, have this part of the body produced in front, but it is very short in these insects, and c;innot indeed be called a rostrum ; moreover, the parts of the mouth are very distinct in the Bruchida;, and their antenna; are filiform, or thickened ; whereas, in the weevils, the mouth is exceedingly minute, and placed at the extremity of the rostrum, with the palpi scarcely visible, and of a conical form. From some of the wood-boring insects (Xylophagn, Bostrwlndce, and especially Scolytus), the less cylindrical form of the body, and the greater elongation of the rostrum, will serve to distinguish the curculionidae. When we consider " what dire events from trifling causes spring," and find the truth of this line con- firmed in a thousand different ways by the agency of the minute objects of the creation, we may perhaps be not greatly surprised that the weevils (although furnished with a mouth, the various organs of which are so exceedingly minute, as to be apparently in- capable of causing much detriment) are amongst the greatest enemies to the vegetable stores of mankind found amongst insects. Hence, there are no species so interesting in their economy, and so well worthy of being investigated in their different states, as some of those under consideration, since it is evident that it can only be by a positive acquaintance with the various times and places in which these creatures pass through their various states that we can ever hope to arrive at certain remedies against their attacks. We have already, in our article CALANDRA, given an account of the ravages of one of the most destructive insects in the family, viz., the corn weevil, and shall not therefore, in the present instance, enter further into the details of the habits of that particular group. The great extent of this family, together with the minuteness of many of the species, render it very difficult to arrive at a knowledge of the various individuals of which it is composed. In the former respect, this group offers another curious instance of the great increase in our knowledge of the insect world, in addition to those which we have mentioned in former articles. At the beginning of the present century, Latrcille stated that the family contained 800 or 900 species; Dejean, in 1821, gave 1073; and Scho3nherr, in 1833, 3544 ; since which many others have been discovered ; so that, in twelve years, the number of species has been more than tripled. The European species of this family are, for the most part, of small size. Amongst these may be mentioned the genus APION (which see) ; but the Indian and Brazilian species not only acquire a very considerable size, but are adorned with the most splendid colours. The diamond beetle (Enlinms imperialis) may be cited as the best known example. This insect is of very common occurrence in the country which it inhabits, and is brought to Europe in great numbers ; but opticians and others, who prize it for its splendid appearance, often demand nigh prices for large specimens. We have observed, that the most brilliant mode of examining this insect is to hold it near a candle, the light being between it and the eye, and then look at it with a lens of about three or four inch focus, when the effect is inconceivably rich and metallic. The insects of this family are found in all climes ; but the same cause which induces an increase of size C U R C U L I O N I D JE. in the tropical species, operates also in producing1 a much greater extent in the number of species. This cause is found in the nature of the vegetation of those regions where, from its continued growth and vast luxuriance, the herbivorous insects are more nume- rously called into existence to support the regular operations of nature. Many of these insects are also singularly formed, and of very varied colours ; the latter character is, however, of a transient nature, depending on the presence of minute scales or powder, with which the body is covered. Of these, very common examples may be observed in the splendid little green species found so abundantly in the spring on the nettles. The slightest touch, however, removes these beautiful ornaments ; so that, unless the entomologist secures them soon after their appearance in their beetle form, all their beauty will have vanished. Hence it has been fancifully said that the curculionidae are the lepidoptera of scale- winged insects. Like the lepi- doptera, also, their rostrum is tubular, elongated, and capable of being placed in a groove or cavity for its reception on the underside of the front of the body. The larvue of both also feed on vegetables, and these larva; in both are of a totally different form from that of the perfect insects, so that we may regard this as an instance of one of those curious rules which .seem to exist throughout the animated kingdom, which Latreille thus stated more than thirty years ago : — " Nature, in general, has a certain number of models which she re-exhibits (' reproduit '), with certain modifications, in all the classes, and even in the different orders of beings." This principle, which some of our leading naturalists of the present day have held forth, at very great length, as a novel idea, is certainly an interesting mode of viewing nature, even should we not feel inclined to regard it as entitled to so much weight in regulating our classifi- cations of the animal kingdom as some of these authors have been induced to give to it. We will, however, defer to some more convenient opportunity our observations upon the nature of those affinities and analogies which unquestionably exist throughout nature. In their habits, the curculionids exhibit all the symptoms of natural weakness. Of all beetles, tney are provided with the least available means oi defence, and are consequently the most fearful, avoiding both the light and noise ; even the diurnal species are generally to be seen in a state ol inactivity, their colours, resembling those of the substances upon which they are often found, also favouring their security. Unlike the majority oi insects, if they are attempted to be seized, instead ol Unfolding their wings and -lying away, they merely fold up their legs and antennas, counterfeiting death, and falling to the ground. A few of the smallest species (forming the genus Orchcstcs) are more active, the large size of their hind legs enabling them to escape, by leaping to a very considerable distance, in a manner similar to that of the turnip beetle, and other species of the genus Haltica. It is not often that these insects make use of their wings ; indeed, many of the species are destitute oi these organs, their wing-covers being in such cases soldered together. They also creep but slowly, but the underside of their tarsi is furnished with a kind oi cushion, enabling them to retain their hold upon different objects in all positions. It is in the larva state that the curculionidse arc the most obnoxious to mankind ; in the perfect state tney an take but little food, and their chief care is, then, the propagation of their race. Their larvce, like those of the Ccrambi/cidcc, are fleshy, with their legs rudi- mental, or entirely wanting ; but those of the Cur- culwrndcc have the body more or less eylindric, with the extremities somewhat narrowed, so as slightly to resemble a spindle. The head is horny, and furnished with a pair of powerful jaws, and other organs of a fleshy nature. The nutriment taken by these larvae is very diversified, those whose organs of nutrition are most robust attacking the harder parts of vege- tables ; thus the larva, which is termed the palmiste, being the immature state of Calandra pa/iiiaruni, gnaws the trunk of the palms. Other larvae, whose mouths are less powerfully constructed, feed upon the farinaceous matter of various seeds, or the pith of various plants, while others devour the leaves and flowers. A few of the more minute sorts are miners, eating only the parenchyma of leaves. And here we may mention a circumstance, tending to show the incorrectness of the opinion, that those species of insects which feed upon imported plants are not indigenous to this country. The hollyhocks in our garden hafve, for several years, been much injured by the small grubs of one of these insects, which we have ascertained, by rearing them, to produce the Apion radio/uni, a species ordinarily nourished upon the mallow, but which, in this instance, has preferred the hollyhock, probably from its larger size, although mallows were growing within a very short distance from the hollyhocks. The instinct of the parent insect induces her to deposit her eggs in such situa- tions that the larvae, as soon as hatched, find them- selves in the midst of their natural food. We must refer to our articles upon APION, BALA- NINUS, CALANDRA, and other genera, for addi- tional observations upon the natural history of these insects. The beautiful Rhynchites Bacchus (termed by the French agriculturists La beche) does great injury in the vineyards, appearing in June, and devouring the young and tender shoots, extracting the sap by means of its long tubular proboscis. This causes the leaves to roll and shrivel up, and in the midst of these rolled-up leaves, surrounded by a silken covering, the eggs are deposited, from which are produced the larvae, which also devour the leaves. An ingenious mode of destroying these insects has been adopted in France, which we think might be employed with much success in our own country in killing various obnoxious insects, especially those which attack trained plants. The insect, when disturbed, adopts the general mode of defence pursued by its tribe, folding up its legs, and falling to the earth, so that, by holding a small gutter of paper beneath the branch, and then shaking the latter, the insects, being at the time on the point of depositing their eggs, drop into the paper gutter, and are easily destroyed. Another species of this family, Lixus paraplccticm, attacks the- Phcllandrium aquaticum, the larva boring into the stems ; and it is asserted by some authors that horses, which feed upon the infected plants, are subject to a violent disease, which the Swedes term stakra. The thistle, Carduus spinosissimus, nourishes another weevil, whose virtues were highly praised in past times as a specific against the toothach. This insect, accord- ingly, acquired the name of Ciircuho a?itiodonlalgictit; CURRANT. and it was said that, if fifteen larvre of this species, or fifteen of the weevils, immediately after their arrivu at the perfect state, were rubbed between the fingers till all the moisture was gone, these fingers wouk acquire the power of causing a cessation of pain, or touching the affected teeth, for a period of twelve months, notwithstanding all the washing which they might undergo. Truly, our forefathers were not a whit less gullible than their posterity of the present day. When full grown, many of these larvae enclose themselves in cocoons of silk, which, in some species, closely resemble net-work, with open meshes. The great Linnaran genus, Citrculio, has been from time to time divided, by different authors, into various other generic groups, into the details of which it would scarcely be thought profitable were we to enter. This may be conceived, when it is stated that Schuenherr has increased their number to 288. We shall, therefore, content ourselves with giving slight sketch of the distribution of the chief subdivi- sions into which the group is arranged, taking it in its extended limits, and embracing the Attelabides, Bren- lides, and Bruchides, which, together, constitute the sub-section Rhyncophora. 1. Antennae not elbowed at the extremity of the basal joint ; rostrum without lateral gutters, for the reception of the basal joint of the antennae (ORTHOCERI). * Upper lip distinct ; palpi filiform, or thickened at the tips. a Antennae thickened at the tips (Anthribides). b Antennae filiform ; rostrum broad (Bruchides). * * Upper lip not visible ; palpi short, conical. a Antennae filiform, with the last joint alone form- ing a mass (B rent/tides). b Antennae, with the three or four last joints, forming a mass (Attelabides).* 2. Antennae elbowed at the extremity of the basal joint, which is generally received in a gutter at the sides of the rostrum (GONOCERI). * Rostrum short ; antennae inserted near its extre- mity (Brachycerus, Curculio, Hypera, Liparus, and a very great number of other generic divisions). * * Rostrum long, with the antennae inserted near the middle of this rostrum. This division nearly corresponds with the genera Lixus Rync/Keniu, and Calandra of Fabricius, from which a great number of generic and sub- generic divisions have been detached. CURRANT, is the Ribes rubrum, &c. of bota- nists. It is a native of Britain, and has been long cultivated in gardens, and no domesticated plant repays the care and trouble bestowed on it more than this. It is not only a most agreeable and wholesome table fruit, but its pulp and juice are convertible into many excellent confections, and sparkling wine, little if at all inferior to many sorts manufactured from the grape itself. The currant, like all its alliances, are usually and easily propagated by cuttings. These should be chosen from among the most healthy and moderate- sized shoots of the previous summer ; not those rankly luxuriant ones which sometimes rise from the root, nor the slender, dangling growths of the top. * We have altered Latreille's arrangement, by bringing the Attelabides into connection with the Gunoceri, the interposition o( the Brenthidei not appearing to us to be so natural as that given above. The regular form of the future tree depends much on the proper choice and preparation of the cuttings. They should be from twelve to fifteen inches in length, after the knobbed part of the base.and slender points are cut off. All the buds on the lower part of the cutting should be carefully pruned off, leaving only four or five at the top, and which are destined to form the first branches. The cutting thus prepared is dibbed firmly into the ground, about five or six inches deep, as will allow as much for a clear stem, surmounted by the branches, at a due height above the surface of the ground. The cuttings may be planted either in autumn or in early spring, at a foot distance from each other, and on a rather shady spot of rich soil. Here they will not fail to prosper, sel- dom miscarrying, except from extreme drought, or by insects which destroy the foliage and points of the shoots. The young plants will require no care during the first summer, nor till they want pruning in the follow- ing winter. At this first pruning some little skill is necessary in using the knife, in order to get the tree into good form. If the cutting has produced five shoots, the centre one had better be entirely removed , the four remaining (or if there be only three) will be enough of principal branches whence other shoots will be produced to form a head. The most desi- rable form is that of a cup ; the middle being vacant, and surrounded by the fruit-bearing branches at about nine inches apart from each other. This is to be understood of the tree when it has arrived at its required height ; because this form is gradually attained by the assistance of the pruner, in the follow- ing manner : — The first shoots are at the first pruning cut down to one-third of their length ; these in the following summer produce a number of other shoots, some of which are reserved to fill up and complete the form, and the rest are pruned down to about an inch, to serve henceforth as a fruit-bearing spur. Thus the tree becomes annually enlarged till it has arrived at its full size, by which time all the primary and secondary branches will be also furnished with spurs. These spurs yield the fruit and also a birth of shoots every year, which latter are spurred down at the winter pruning. This treatment is, or may be continued for half a score of years, if necessary ; only occasionally cutting away old or worn-out branches, and training up young ones in their places. But there is another way of pruning currant-trees which may be described in a few words : — no spurs are allowed to remain on the old branches, but instead of them a select number of summer shoots are re- served ; and which, in consequence of their fewness, grow strongly. These at the winter pruning are re- duced only one-third of their length ; and the fruit aroduced from these shoots are invariably larger and aner than those produced from spurs. This last- mentioned method of pruning is eligible where quality is chiefly regarded ; and the spurring mode where quantity is the object. It has been a question whether or not it be expe- dient to divest the trees of their summer shoots while the fruit is swelling. Those who practise this process assert, that it assists to enlarge both the bunches, and berries, and also, by admitting the sun's rays, leightens the flavour. This is quite feasible, as the same thing is practised on the grape-vine; but a martial application of the knife in this case is always iroductive of the best results. The best varieties of the currant arc the large Dutch C U RR U C A. 215 white, the common white, large red, long-clustered red, the large Champagne, and the white crystal. They all delight in rich loamy soil ; but will succeed any where if the ground be deep, moderately manured, and somewhat sheltered. The black currant is a distinct species, and also a native of Britain. It is cultivated and increased by cuttings, as are the foregoing ; but the method of pruning is somewhat different. Young plants are permitted to throw out ten or twelve branches from the top of the stem : these are allowed to rise to the height of three or four feet without cutting back. From the lower parts of these many shoots are pro- duced annually : these bear the fruit and only require thinning, none of the young shoots ever being topped. As a constant succession of fruit-bearing shoots rise from below, the topmost ones which have risen too high, are cut out to allow the lower shoots room, and by this means the tree acquires its due form and requisite height. All the currants may be trained to walls or as espa- liers : in which situations they are most conveniently covered from birds and insects, and preserved for table a month or two after the regular season of such fruit. CURRUCA (Auctorum), Warbler. A genus of small fruit-eating and insectivorous birds, belonging to the Dentirostral order, and Sylviadoe, or pettychaps family, and of which the common blackcap (already described in its alphabetical situation) may be cited as a typical example. The bill, in the more charac- teristic species, is ruthe.r stoutish, at least for birds of this family, and is somewhat compressed : the gape almost smooth ; the nostrils basal, lateral, oval, and exposed ; wings with the first quill-feulher very short, the second inferior to the fifth, and the third and fourth generally the longest ; legs having the tarsi longer than the middle toe ; toes short, and formed for perching ; hind toe strong ; the sole dilated and broad ; claws much curved, grooved at the sides, and very sharp, that upon the hind toe strongest, and of greatest length. This is one of the numerous and very distinct natural divisions which were formerly brought to- gether and included in the immense Linnaean genus Motacilla, a huge and incongruous division, which was first reduced by Dr. Latham, who restricted that term to the wagtails, properly so called, but who again confounded, in his most comprehensive genus Sylvia, every small bird of a certain size which agreed in possessing a comparatively small and slender bill, however in other respects dissimilar. That designa- tion also, in its turn, has now been limited to a particular group, the members of which exhibit some degree of resemblance in all their characters, and which therefore forms a most natural division ; and the nightingales, the wheatear, the redstarts, the accentors, the aquatic warblers, wrens, goldcrests, and a host of others equally dissimilar (including the present group), all of which were formerly arranged together under the one name Sylvia, are now distri- buted into various independent genera, each known by a separate name, and distinguishable by well- marked and obvious characters. There are three principal divisions of European warblers, that is to say, of small, soft-billed, mostly migratory, insectivorous birds, which chiefly seek their food about the foliage of trees and bushes ; for the term warbler, as usually and technically applied in works on natural history, has little or no reference to the vocal powers of these birds, a few species wii*ch excel in song having imparted this name to the whole group of which they are members. If we set aside, in the first place, the different wagtails and pipits ; secondly, the robin and wheatear tribe ; and thirdly, I he different titmice and allied genera, each of which forms a very natural sub-family of the Sylviance, we have still, apart from the flycatchers and other tribes which usually take their insect food upon the wing, three leading subdivisions of small, migratory, ar- boreal, and insectivorous European birds, each of which contains a considerable number of species, and which, together, constitute what is called the Sylviadee, or typical sub-family of the Sylviadce. The first of them, comprising what are commonly called the different " willow-wrens," a number of little delicate birds with green plumage, and peculiar in their form and characters, will be fully described in the article SYLVIA ; the members of the second, which are inhabitants of aquatic situations, breeding among the reeds, willows, and sedges, and which are in other respects very different from the rest, will be men- tioned under the generic head SALICAIUA ; and the third, the Sylvan, or fruit-eating warblers, as they are appositely termed, a most natural group, now gene- rally recognised under the name CUKRUCA, are the birds we are now about to speak of. These three generic divisions, with one or two exceptions only, comprise the whole of the European species, which, in books on natural history, are usually denominated " warblers." We would restrict the term altogether to the last mentioned genus. The most typical of the fruit-eating warblers are inhabitants chiefly of woods and thickets, orchards and gardens, some of which are less so, however, being found more along the hedges. They are all songsters, and most of them warble for a long time continuously, raising their voice as they proceed, and some of them invariably terminate with a loud and liquid flow of pleasing melody. They are mostly migratory birds, some of them being found in summer as far north as Lapland ; but none are known to occur in winter, even in the most southern of the European countries, except as stragglers ; a few of them, however, in the north of Africa, are more stationary. They feed upon various insects (more or less, according to the species) ; and they are very expert at capturing the winged ones as they fly by, but they never dart after insects like flycatchers, following them upon the wing, though this is some- times done by all the Sylvias and Salicarice. The writer of this has kept all the British species in confinement, and when tame, and suffered to fly loose about a room where there were plenty of flies, of which they are all extremely fond, he has often had occasion to observe, that, however quick they were at catching all that flew within their reach, they had not the slightest notion of following them into the air, as a willow-wren or redstart would have done. They invariably refuse earth-worms, and many sorts of caterpillars, but some they are extremely fond of; this, however, depends much upon the species, the garden warbler devouring several which are rejected by the whitethroat, and vice versa. In autumn they subsist more upon fruit, and various berries, of which they are very great devourers ; some of them, indeed, feeding on little else during their whole stay with us, ivy and privet berries, and the like, supplying the 216 C U 11 R U C A. place of garden fruit during the spring. They all frequently erect the feathers upon the crown of the head and throat, and whilst doing so, not unusually emit a sort of check, or tchut, which varies a little in the different species, and much resembles the sound produced by tapping two pebbles together. This note must be familiar to most persons residing in the country. It sometimes indicates suspicion, or fear, as it is uttered whenever they espy an enemy, but is also expressive of various other emotions. They are mostly shy and hidling in their habits, concealing themselves amidst the thickest foliage. Their colours are chaste and unobtrusive, and they would in general be very little noticed, were it not for the almost incessant warbling of the males. They chiefly nidi- ficate in low bushes ; the blackcap and the garden warbler, however, often build in a forked branch, at four or five feet from the ground, and the lesser whitethroat sometimes at the height of nine or ten feet, but all of them most commonly near the ground. The nest is of rather flimsy construction, but firmly put together, composed chiefly of the dry withered stems of catch-weed or goose-grass (Galium aparinc), woven into a kind of basket-work ; in some species always with a little green moss on the outside, and lined with fine dry grass and horse-hair, with the addition, in some species, of small fibrous roots. There is not a more remarkable fact, nor one more indicative of the entire and absolute distinct- ness of our different small birds, than that every separate species invariably constructs its nest in a manner so peculiarly its own, that a practised eye would never mistake it for the nest of any other species ; the materials, perhaps, may vary a little according to the locality, though even this is seldom the case, and never in any very remarkable degree yet the mode of construction is always so precisely similar in different individuals of the same species that there is never much difficulty in identifying the nest of any one of them. Still, however, notwith- standing this distinctness, there is always a great generic similitude in the nests of different birds of the same natural genus, similar to that which obtains in the birds themselves ; and the more the birds approxi- mate, the more closely (as the term is) they are allied, so in the same ratio the more do their nests resemble ; each, however, still preserving some pecu- liar distinctive characters by which it may be always known. Indeed, if we trace also the various inter mediate links, which almost imperceptibly connec the most dissimilar forms together, we may almos always observe a regular gradation in the nests, simi lar and corresponding to that which prevails in th< birds. The same gradation is likewise very often observable, even in the very notes and songs of birds in the nature and disposition of their colours an markings, and in the colours and markings of thei eggs. A practised, ear will at once distinguish ever separate species by its peculiar notes ; as in the genu Currucn, the subject of the present article, those of al the different species of a natural genus may have a very strong generic similitude, yet each is alway readily distinguishable from all the others. As we meet with no mule productions in a state of nature no intermediate specimens, so we find no interme diate nests, nor hear intermediate notes ; each pre serves in every respect its specific characters. I will be conceded that the most remarkable generi resemblances are those of the nests ; yet so truly doe bis obtain, that, in many instances, both generic and pecific divisions may almost as safely be deduced rom an examination of these as from the study of the )irds themselves. In the present instance we have not entured to give a generic description of the nests of all the species of Curruca, although that of each eparate species presents invariably certain marked )eculiarities, by which it may always be at once dis- inguished from those of any of its congeners, how- ver, on a superficial view, these may resemble it. A common species of Curruca in the south of England is THE GARDEN WARBLER (C. hortensis), one of the most delightful songsters of this or any country, but which, notwithanding, is most wonderfully little known to people in general. In size and form it very closely resembles the black-cap, indeed so much so, that an albino or white specimen of either could not very readily be distinguished. It is, however, somewhat shorter than that bird, and rather more thickly made ; all over of an almost uniform olive-brown colour, rather paler about the throat, and inclining to white upon the belly, and usually having a dash of grey upon the sides of the neck. This is one of the latest of our summer migrants to arrive in spring, and also one of the first to depart, in this respect differing widely from the black-cap, which is always one of the first of the summer birds to make its appearance, and one of the very last to leave us ; a difference, by the way, which is singularly enough observable in several migrant birds, that are nearly allied to each other. The garden warbler is never abundant in this country till the trees are in full leaf, but its presence is always soon announced hy the delightful flow of soft and pleasing melody which it pours forth, often from the top of some tall pear-tree, or, if not in a garden, generally from amid the branches of an elm. Sometimes he commences with some low twittering notes, not much unlike the song of the swallow, and raising his voice by degrees,through a series of charm- ing and most delightful flute-like modulations, he ends with the full rich whistle of the blackbird, but delivered in a more hurried cadence. He usually continues singing about three or four minutes, when he stops as if to take breath, and almost immediately commences again ; deep, rich, and mellow, his lovely warble is heard nearly throughout the day, and occasionally even after sunset, singing nearly throughout the sum- mer, and as the season advances often both beginning and ending with the same loud blackbird notes. As in all other birds, some individuals are much finer songsters than others. The garden warbler does not appear to be quite so generally dispersed over the country as the blackcap, though it may be more so than is commonly sup- posed, as it is often confounded with that bird. It is certainly very abundant in many parts of the south of England, and particularly near the metropolis ; and Mr. Selby states that it is found " throughout the greater part of Scotland, particularly where the wooded districts margin the lakes and rivers." Mon- tagu traced it through the greater part of England. Both this species and the blackcap frequently com- mence singing a few seconds before they settle, as they fly from tree to tree, continuing their song unin- terruptedly after they have alighted. Indeed, these two species resemble each other most closely in their general habits, and the history of the latter, as given in the article BLACKCAP, applies in almost every respect to that of the garden warbler. They are both great C U R R U C A. 217 devourers of fruit, which they prefer to insect food ; insomuch that, in confinement, when they first begin to get a little tame, they will frequently descend from their perch to eat fruit from the hand, when a buz- zing fly has no attraction for them. In some of the species, as the white-throat and babillard, the reverse is the case, as, though extremely fond of fruit, these will sooner come down to a fly. The garden warbler is, perhaps, a greater devourer of caterpillars than any of the others, and in confinement will eat seven or eight in succession, of the caterpillars of the large white cabbage butterfly (Pontia brassier), which the others will not even touch. Its most favourite fruit seems to be the Kentish cherry. Allied to this bird and the blackcap (C. atricapilla), there are several continental species, most of which have the outer tail feathers white. One of these, the C. sarda, chiefly inhabiting Italy and Spain, is said to be a charming songster. Another, the C. mclanoce- phala, has very little melody to boast of. The C. Ruppellli is a beautiful species, the male of which has the head and throat black, divided by a white line ; this chiefly inhabits Barbary, and occurs, but only as a straggler, in the south of Europe. Further south we have the C. Heinekia, which, with the common C. atricapilla, is resident throughout the year in Madeira, and is said to be a fine songster. The C. nisoria is a European species, remarkable for its curiously spotted plumage ; and the C. orpkea, an inhabitant of the south of France, is a very pleasing songster, resem- bling in its habits the common whitethroat ; this bird also has the crown of the head black, and is remark- able for generally nesting in society. The two last- mentioned species are of larger size than the rest. ' AH account of the babillard or lesser whitethroat (C. garrula) has been given in its alphabetical situation (see BABILLARD) ; closely allied to it are the C. pas- senna and C. Icucopigon, both European birds. These three are of smaller size, and more restlessly active than the others. Their habits are intermediate be- tween those of the blackcap and whitethroat. The last-mentioned bird (C. cinerea) is exceedingly com- mon throughout the British islands, arriving in the southern counties about the middle of April, and frequenting hedgerows and commons that are covered with furze or brushwood. It is more a bush bird than any ',i the others, and frequently rises singing a little aw,iy into the air, a habit which is peculiar to it and perhaps the spectacle whitethroat (C. compi- cillat t), a smaller but very nearly allied Italian species. Th se too have the bill shaped somewhat differently from the typical or blackcap form, approaching more a a miniature of that of the blackbird ; in this, and in the habit of singing upon the wing, approaching to the Dartford warbler or furze wren, a species we shall presently describe, and which belongs to a separate subgenus. The whitethroat is an extremely lively :iiid active little bird, almost perpetually singing, and ever erecting the feathers upon the throat and crown of the head, together with the tail, which gives it a characteristic appearance. The adult male has the irides yellow, the crown and region of the eyes dark grey ; the whole upper parts reddish brown, tinged with grey ; and the wing coverts and tertiaries broadly margined with mahogany. The throat is white, and the breast faintly tinged with rose colour, the latter hue being wanting in the female, which all over inclines more to reddish brown ; tail rather long, the exterior feather being a little shorter than the rest, and having its outer web and tip white. All the birds of this genus may be readily known, as soon as hatched, from the other tribes of warblers, by their having the inside of the mouth and gape invariably red ; they leave the nest before they are half fledged, and skulk about the bushes, being only for a short time fed by the parents, who very soon commence again the work of nidification, and commonly rear three broods in a summer. The whitethroat, like the rest of the genus, frequents gardens and orchards in the fruit season, being a great devourer of cherries, currants, and the other smaller fruits. It appears to be a very long-lived bird ; for Mr. Sweet kept one in confinement for fifteen or sixteen years, at the end of which time it is described to be as active and lively as at first, to sing as merrily, and to show no sign of old age. They are very tame and familiar, and rather a hardy bird in confinement, and very amusing from their liveliness, singing with great spirit and energy against any other bird ; but, like the rest of the genus, they are very subject to a partial loss of feather during the winter. This species is exceedingly abundant upon open commons and furze-brakes, where its habits closely resemble those of the FURZE WHEN or DARTFORD WARBLER, as it is generally but not very appropriately called (C. meli- gophilus provincialis). This species was separated from the others by Dr. Leach ; it is of small size, with a bill like that of the whitethroat, but longer in proportion ; the tarsi also are rather longer than in the typical Currucae, the tail is much elongated, and the wings are short and rounded ; in all which respects it approximates to the genus Malurm, an African group of warblers ; it does not, however, construct a domed nest like those birds, but in its nidification and eggs closely resembles the whitethroat and other currucae. This curious little bird was first discovered in England, near Dartford, in Kent, whence it has been usually denominated the Dartford warbler. It is rare however in that neighbourhood, although generally speaking, wherever it is found, it occurs in abundance. It is plentiful enough upon some of the commons in the southern counties, inhabiting only the very thick- est furzes, where its habits are so very shy and hiding that a person might traverse for months various situa- tions where it literally abounds, without being once aware of its presence. It has consequently been usually considered a very rare bird, though it certainly is an extremely local one. Perhaps it is no where more abundant than in the adjoining districts of Surrey and Sussex. This bird is a little larger than the common wren, but much longer including the tail, its total length being about five inches and a half, of which the tail measures almost half. Its weight is about two drachms and a half. The eyelids are yellow, inclining to orange ; irides reddish yellow, whence in Sussex they are provincially called " Red-eyes." The bill almost black ; base of the upper mandible whitish. The whole upper parts dusky brown ; cheeks dark asii colour ; two outer tail feathers tipped, and the outer one also edged with white. The throat, neck, and breast, dark cochineal red, inclining to purplish red ; in the young of the year, the feathers of these parts have each a fine streak of white. Legs and toes yel- lowish brown. This bird, when flying, has a very dark appearance, seeming to be almost black. It differs from the other species in being resident in this 218 CURSOR1US — CUSTARD APPLE. country throughout the year ; and, perhaps, the best time to see it is upon a line frosty morning, at which time it appears extremely active and lively ; it is constantly in motion ; erecting the crest and tail, and uttering a low note, resembling cha, cha, cha; it also sings prettily, sitting on the topmost branches of the furze, but the song wants variety, being always the very same over and over again. Sometimes it mounts singing a little way into the air, or suspends itself over the furze ; but at the least alarm it will descend into the covert, and it will be a long time before you can get another sight of it. It trusts entirely to conceal- ment for protection, threading the intricacies of the thickest bush with great rapidity ; and if in a solitary detached bush, you may knock about for ever without bringing it out ; it will sooner suffer itself to be taken by the hand. Both nest and eggs of this bird are very like those of the whitethroat, and the young quit the nest in the same manner, before they are half fledged : at this time the artifices of the parents to draw an intruder off are very amusing ; they make the same harsh sound as the whitethroat, and will almost suffer the hand to touch them, and then, perhaps, will fall from the spray, and tumble along the ground, as if fluttering in the last struggle for existence. In confinement its habits resemble those of the whitethroat and its congeners, and it feeds on the same food ; this it will frequently take while suspended to the wires with its head downward. It will also sometimes climb along the wires, a habit which, among the British warblers, is peculiar to this species and the lesser whitethroat. Both these little birds, also, in the cage, frequently perform somersets in the air, throwing themselves over backward ; and both of them, at times, will utter a singular sort of rattling note peculiar to themselves. The furze wren is found in some parts of Germany, and is very common in the south of France ; from its abundance upon the com- mons in Provence, it has received the trivial name of Provincial^. Buffbn was the first to describe it, which he did under the name of " Ic Pilchou de Provence." CURSORIUS— Swift-foot, a genus belonging to the pressirostral division of Echassiers,w stilt-birds, of which the generic characters are as follow : bill slen- der, conical throughout, and with a moderate gape ; wings very short, or of mean length, second quill the longest, the coverts as long as the quills ; tarsi long and slender ; toes three, all horned to the point, and without any web. These birds form a sort of intermediate link be- tween the ostriches and the plovers, they are birds of the deserts, shy and retired in their manners.and found only in the warm parts of the eastern continent ; but one of the species, at least, is discursive over a great range of surface, and makes a dash into the southern parts of Europe, and even into England. They are, perhaps, the fleetest footed of birds ; and, if they are not come upon by surprise, or in places which are new to them, and in which they get bewildered and entangled among bushes, they are out of the reach of fire-arms in no brief space, so that very few of them are found. Of their time and manner of nesting, number of young, and other points of their economy in their native wilds, we are altogether ignorant. Three species, at least, are known. CURSORIUS ISABELLICUS — common Swift-foot. A native of the northern parts of Africa: Isabelle yellow, or reddish cream colour, on the upper part, white on the uader ; top of the head red ; two black rays over each eye, separated by a patch of white ; wing coverti bordered with ash colour, quills black ; bill black ; legs ash colour, length between nine and ten inches.— Sometimes, but very rarely, straggles into England. CURSORIUS BICINCTUS — two collared Swift-foot. Also a native of Africa. Upper part brownish ash, each feather margined with reddish white ; middle coverts of the wings reddish, quills black ; rump white, under parts reddish ; a narrow black collar on the lower part of the neck, and a broader one on the breast ; rather larger than the former. CURSORIUS ASIATICUS — Coromandel Swift-foot. A native of India. Brown on the upper part ; top of the head, back of the neck, and breast, maroon red ; lower belly and quills black ; coverts of the wings ash-coloured, with white tips, and a black spot near the tip ; thighs and coverts, and feathers of the tail, also white ; bill black ; feet yellow. This species is rather the small- est of the three ; but there is no great difference in size between any of them. The last two have not been seen in the west of Europe. CURTISIA (Hortus Kewensis). This is a tree from the Cape of Good Hope, named in honour of W. Curtis, founder of the Botanical Magazine, and other works relative to plants. It belongs to the natural order Cclastrinece, is treated as a greenhouse plant, but had never flowered in this country before 1831 ; according to the late Mr. Sweet, at the Cape it is called the Hassagay Tree. CUSCUTA (Limueus). This genus is one of the most curious vegetable parasites known. Two species are indigenous in Britain, and there are six or seven foreign species. It belongs to Pentandria Digynia, and to the natural order Convolvulacets. Generic cha- racter : calyx of four or five lobes. Corolla some- what globular, persisting, four or five cleft, and having scales at the base : stamens growing to the tube of the corolla ; capsule two-celled, opening at the base ; cells two-seeded. The dodder, as it is called in Eng- land, rises from its seed like any other dicotyledonous plant, and is supported by its own roots until its stems can lay hold of some other plant. This it holds in a firm embrace, inserting small fibres or suckers into the bark of its supporter, whence it draws nourishment after its own roots are dead. The nurse often dies under the burthen and exhaustion caused by the para- site, which is not very nice in its choice of a foster parent ; heath, furze, broom, or thistles are equally relished by the incumbent ; and, if introduced into the greenhouse by accident, riots among the plants there as unceremoniously as if it were on its native com- mon. The dodder is sometimes raised as a curiosity ; seeds are sown in pots, and when the seedlings are strong enough, they are placed close to the side of some soft-wooded, worthless plant, which they soon lay hold of and cover, extending a considerable dis- tance around, if not prevented. The plants flower abundantly, and some of the species are fragrant. CUSTARD APPLE. (The fruit of a genus found in the East and West Indies, called Anona by Linnaeus, because so named by the inhabitants of the Island of Banda, where some of the species are found. Indeed these fruit-trees are cultivated in gardens all over India, on the continent as well as on the Islands in the Indian Sea. In value and quality the fruit may be compared to some of our common pears, but with a less firm pulp, so soft, indeed, as to be easily sucked out of the skin. The Anona cherimolia, a native of South America, is said to be a fruit of very CUTANEOUS SYSTEM. 2i9 prsat excellence, and by some preferred to all ouiers. The sour and sweet sops of the West Indies are the muriated and squamose fruited custard apples ; and are found useful even in that region of tine fruit- Some of the species have fruited in our stoves ; and no doubt were their culture more attended to, by working the plants, and allowing space for their roots and branches, the fruit may be brought to a conside- rable degree of perfection. These plants require a rich loamy soil, and are propagated by ripe cuttings struck in sand. CUTANEOUS SYSTEM, comprehends the J skin and its appendages, hair, wool, bristles, spines, horn, hoofs, feathers, shells, crusts, scales, and other analogous structures. Tiie skin is composed of three layers of integu- ments viz., the Epidermis, or cuticle ; the Rcte witwfium, or mucous web ; and the Cutis vera, or true skin. The epidermis, or cuticle, which is the external layer, is a dense semi-transparent, partially elastic membrane, which is common to all animal and vegetable bodies. It is everywhere continuous in its course, being reflected inwards into the mouth, nostrils, windpipe, gullet, and other open passages. By Dr. Munro, it was traced down as far as the cardiac region (upper portion) of the stomach of a horse, and by many physiologists it is supposed to line the whole tract of the alimentary canal. It invests the roots, stems, leaves, and flowers of all plants, forming an external covering, which protects them from the action of fluids, and from the extraneous effluvia which are constantly floating in the atmo- sphere. In thickness and texture, both in animals and vegetables, it varies exceedingly. It is very thin in birds, and along the mesial abdominal line of fish. In some animals, however, as the elephant and rhinoceros, it is so thick and impenetrable, that it constitutes an urmour of defence which resists the assault of arrows, swords, javelins, and even musket- balls. It is thinnest in the human body around the lips, at the tip of the tongue, and at the extremities of the ringers ; hence the sense of touch is most ex- quisite in these parts. It is thickest in the palms of the hand and in the soles of the feet, where, from repeated pressure, it is often converted into a dense horny substance. This thickness, however, is not altogether the result of pressure ; for, even in the new-born infant, the cuticle in the palms of the hands and the soles of the feet is thicker than in any other part of the body. Its thickness, in like manner, varies in different plants. In the leaves of the pearly aloe it is very thin and delicate ; around the trunk of the plane-tree very thick and coarse. Although insensible, this integument is still to be regarded as a part of the living system, for it is constantly under- going decay and renovation. From the human body it continually exfoliates in small scales, and in some persons in very large patches, especially after sick- ness, on account of the vessels, which may be regarded as the connecting link between it and the subjacent layer, having become debilitated. At certain seasons of the year some animals, as serpents and caterpillars, cast their skin in an entire sheath. It is the same with plants. From the birch and currant tree the cuticle peals off constantly in small scales ; from the elm it is detached in large flakes. The connexion between the cuticle and the subjacent layer of skin is very close ; it is, however, readily separated by blisters and by heat. Alcohol alflo loosens it in many of the inferior animals, as may bo observed by immersing worms in this liquid. When the cuticle of the blistered surface has been thus destroyed, it is very speedily renewed — more speedily, indeed, than any other tissue of the body. The skin, being the outer covering of the body, and affording it a surface of protection, does not readily absorb extraneous matters ; yet, when the epidermis or cuticle is removed, and the subjacent layer laid bare, then absorption takes .place very rapidly ; hence, in order that the operation of inoculation or vaccination shall take effect, the virus must be introducod below the cuticle. This has been a subject of some contention ; for, although the cuticle does obviously permit the trausudation of sensible perspiration, the pores through which it passes are certainly not perceptible. The fact of cuti- cular absorption (says Dr. Milligan, after reviewing the experiments of many philosophers) may be thus stated : — The cuticle has no absorbing orifices open- ing on its surface, and the substances supposed to be taken up by these really make their way into the body by the action of the absorbing vessels of the lungs and subjacent cutis vera; yet, from the imbib- ing faculty common to the cuticle with dead or unor- ganised matter, many substances may, by long macer- ation or exiernal violence, find a passage through it without any laceration being visible. It may be pro- per, however, to observe, that pores running in a spiral direction have been discovered in the cuticle of the whale ; and, arguing from analogy, it may perhaps be inferred that similar spiral pores exist in the human cuticle, although so minute as to escape demonstration. The eminent Amici has, by the aid of his powerful microscope, shown that oval orifices, or stomata, as they are called, exist in the cuticle of plants, especially of those which have a green colour. No such stomata have, however, been detected in aquatic plants ; their use, it is presumed, is to exhale water and absorb air. There are many provisions in animals to preserve the cuticle in a healthy state, which consist principally in secretions of an* oily or viscid nature. In fish and mollusca it is defended from the action of the water by a viscid or glutinous secretion, which is continually poured out on the surface. This secretion keeps the skin of whales soft and smooth, like oiled silk, and enables them and other aquatic animals to emerge from the water with the cuticle dry. It is in some cases glairy and adhesive, as in the common slug ; or mucous and slippery, as in the common eel. The cuticle of animals is, in the living body, readily distended, as may be observed by its extension in tumours, or swellings of subjacent parts. It is, however, less elastic in plants. When overtight, it causes contrac- tion of the stem, as may be often seen in the plum or cherry-tree ; and when subjected to pressure from unnatural excrescences, it is frequently ruptured ; so also, when the trunk of a tree, as the oak or the elm, has attained a certain size, the surrounding cuticle cracks, and the surface of the trunk becomes rugous. Immediately below the cuticle, and intermediate be- tween it and the cutis vera, is the second layer of the skin, which was supposed by Malpighi to be formed of a peculiar mucus, wherefore it was called the RETE, or CORPUS MUCOSUM. Other authors regard it as a vascular net-work ; and M. Gall supposed that, it consists of matter similar to the brown matter which 2-20 CUTANEOUS SYSTEM. exists in the brain. It may be described as a thin extended puJpy layer. It is the seat of colour, being white in the European, copper-coloured in the American, and black in the negro. Haller, Camper, and Blumenbach, doubted its existence in very fair persons. It is certainly not seen distinctly excepting in the negro. The different complexion or colour of mankind, in different regions of the globe, has, it is notorious, given rise to various opinions and speculations ; by some, being referred to a difference in original or- ganisation ; by others, being ascribed to the influence of climate, food, and other secondary causes. That this rete mucosum is, however, really the seat of colour, there appears to be no doubt ; and the following ingenious theory in explanation has been proposed by Blumenbach : — The human body, it is well known, throws off a vast quantity of carbonic acid ; that is, carbon in combination with oxygen gas. He supposes, then, that this carbonic acid is in this mucous layer decomposed, the oxygen is set free, and the carbon or colouring matter deposited on the mucus, which combines with it. This decomposition is presumed to be determined by the intense light and heat of a tropical climate ; those parts of the body, therefore, which are protected from the light and heat of the sun, are not so dark as those which are more exposed. The palms of the hand, and the soles of the feet, are not in the negro so black as the face, neck, and back of the hand. African ladies, •who live in the shade, have a much paler complexion than those who are much occupied in the open fields. It is darker in some parts of the body than in others, as in the eyelids and arm-pits. According to Cuvier, the shell of molluscous animals, the crust of the lobster, and other Crustacea, occupy the place of this layer. It also degenerates into the thick dense horny substance, which form the beaks and claws of birds, and the claws of other animals. Under the cuticle of plants, the corpus mucosum is also found, and is described as the cellular integument (envelope ccllulaire). It is very obvious, in mosses and ferns, and is in plants also the seat of colour, being green in young stems, and white in those which are colourless. Mirbel remarks, that leaves consist almost entirely of this substance, covered on each side with cuticle. The stems and branches of both annual and perennial plants are invested with it ; but in woody parts it is dried up and re-produced continually, such parts only having that reproductive power. The old layers remain, are pushed outwards by the new ones, and form at length the rugged dry dead covering of the old trunks of trees. In the Quercus suber, a species of oak abounding in dry mountainous districts in the south of France, and in Spain, Portugal, Italy, and Barbary, this herbaceous envelope is remarkably thick, light, and .porous, and constitutes what is well known as the cork of commerce, a substance which was well known to the Greeks and Romans, who used it as stoppers for vessels (Pliny,Hist. Nat., lib. xvi. cap. 8.), although it was not extensively applied to this pur- pose until glass-bottles were introduced, which was generally done in the fifteenth century. In this part of the plant the principal changes of the sap take place, and an operation is effected which is of vast importance in the economy of nature. Already it has been stated, that the human body throws off continually a certain quantity of carbonic acid gas ; by the respiration alone about a pound of carbon is got rid of daily ; mammalia, and inferior animate, likewise expire it ; as do also plants when in the shade. This being a very noxious, indeed poisonous gas, it may reasonably be asked, how the atmosphere is purified from it, and the earth rendered fit for the abode of living beings ? Herein the wisdom of creative Providence is beautifully illustrated. Car- bonic acid is composed, it has been said, of carbon and oxygen ; the carbon is the basis of vegetable bodies, the characteristic ingredient of all kinds of charcoal. When the sun shines upon a plant, its leaves absorb the carbonic acid from the atmosphere, and decompose it ; and this takes place in the herba- ceous envelope ; here the oxygen is set free, and the carbon left to be appropriated to the basis of the plant. The vegetable creation, therefore, is con- stantly purifying the atmosphere, yielding for every volume of carbonic acid which it absorbs an equal volume of pure oxygen. Upon this principle, some have supposed that, in the beginning of the world, plants were created before animals, and gradually purified the atmosphere, so as to render it fit for their abode. Be this as it may, the provision is exceed- ingly interesting, and calculated to excite the admi- ration of every reflecting mind. Underneath this mucous layer, or rete mucosum, is the cutis vera, or true skin, which exists in all animals; but is less distinct in mollusca and Crustacea. In quadrupeds it appears to consist of solid fibres, which cross each other in every direction ; in fish it seems an homogenous and continuous membrane. Over this integument, an infinite number of blood vessels, and the extremities of nerves are distributed ; so that it is properly speaking, the seat of the sense of touch. It is provided also with a vast number of little eminences or papillae, which were discovered by Malpighi in the foot of a pig, in each of which the extremity of a nerve is supposed to terminate. These papillae are particu- larly conspicuous in the parts most appropriated to the sense of touch ; as the tips of the fingers, the point of the tongue, and the lips. They are also well seen in the bills of aquatic birds, as the swan, goose, and duck, and doubtless enable these birds to find the food concealed in the mud. They are also larger upon the lips of fish ; on the toes of birds which, like those of the parrot kind, use their feet as organs of prehension; and round the lips of the shrew, the mole, and animals that burrow under ground. The vessels of this true skin throw off the watery part of the bloou in the form of insensible and sensible perspiration ; the former escapes imperceptibly, the latter percep- tibly. By some it is considered doubtful whether the vessels of insensible are the same as those of sensible perspiration ; the fact that the dog perspires insen- sibly, but does not perceptibly, favours the idea of the two kinds of perspiration being dependent on a dif- ferent set of vessels. The cutaneous perspiration serves several important purposes in the animal economy ; it keeps the outer skin or cuticle moist and supple ; it favours the exercise of taste and touch ; and regulates by its evaporation the temperature of the body. The cutis vera is also supplied with a number of little organs called follicles, which secrete an unctuous and sometimes sebaceous matter, varying in consistence, odour, and other qualities in different animals, arid which, as already premised, preserve the skin in a healthy state. The vessels also of the true skin secrete carbonic acid, which is discharged from the surface of CUTANEOUS SYSTEM. '2-21 the body : so that, besides being the organ of touch the function of the skin is vicarious with that of the lungs, serving to remove the superfluous carbon from the system. It serves the same purpose even with fish ; for Spallanzani and Provencal found that the skins of fish produced carbonic acid as well as their gills. Although in plants an epidermis or cuticle, and envelope analogous to the rete mncosum, is found to exist, they do not appear to possess any integuir.ent analogous to the cutis vera, which, in descending the scale of organisation, may be said to terminate with the Crustacea. The skin then of animals is found to consist of these three layers, which, when chemically examined, are discovered to be composed almost en- tirely of gelatine, an animal principle which united with tannin, forms the remarkable substance leather. When the skins, therefore, of animals are macerated in bark, the tannin of the bark, uniting chemically with the gelatine of the skins, forms this compound, which is insoluble in water, resists putrefaction, and becomes hard and tough when dry. The cutaneous system of animals and vegetables comprehends also, as already mentioned, the appen- dages to the skin ; such as hair, wool, horn, feathers, shells, &c. HAIR is common to all mammalia, whales not excepted ; it also occurs, mixed with feathers, round the head and neck of certain birds ; it is, how- ever, absent in reptiles, fish, and mollusca, although found to exist in many annulose animals, and even zoophytes. Every individual hair may be described as consisting of a hollow tube proceeding from a root or bulb below the cuticle, and terminating in a very fine point. The bulb is of an ovoidal shape, and con- sists of an external and internal covering — the former b*ing composed of condensed cellular tissue; the latter being a simple membrane which lines the interior of the tube. The cuticle introduces itself into the bulb, and having become attached to the hair at its root, is reflected back again ; hence the hair holds firmly to the skin. The tube arising from the bulb is filled with a soft matter called the medulla or pith of the hair, which is the seat of a kind of imbibition whereby the colouring matter secreted by the vessels of the bulb is raised so as to give an uniform colour to each individual hair. The human hair is generally either black, brown, auburn, yellow, or red ; besides which a white variety characterises the race of people termed Albinos. When the vessels which secrete this colour- ing matter, and which also nourish the hair, become debilitated — or when the secretion is interrupted by any violent, mental emotion, the hair turns grey, or becomes purely white. This happened, it is well known, to the unfortunate Louis XVI. of France, the nijjht previous to his execution ; — also to Marie Antoinette, the queen of France, whose hair became white during the period of her journey fromVarennes to Paris. It also occurred to the unhappy queen Mary ; and many other cases of a similar description are on record. Sometimes even after the hair has turned grey during a period of affliction, it will after- wards recover its natural colour — and this loss and recovery of colour has occurred to some persons in a verv short space of time. Black hair has been gene- rally considered significant of a vigorous constitution ; white, on the contrary, was called by Lord Bacon the " colour of defect," and is regarded as a sign of de- bility. Hence, horses with white feet, are thought to be more tender and susceptible of disease than those of a more uniform dark colour. When the ves- sels which nourish the roots of the hair become debili- tated, as in extreme old age or after sickness, the bulb collapses, its attachment to the skin is destroyed, and the hair is shed. This sometimes occurs irresnlarly and in patches : sometimes the disease is universal, and not a hair remains on the surface of the body. This occurred to the chevalier D'Eperney, who, after four months' studious application, and without any illness, lost his beard, eyebrows, eyelashes, and all the hair of his head and body. Certain kinds of diet, especially a fish diet, is said to produce baldness. In the Shetland islands, so common was baldness formerly, that it was a common saying that "there was not a hair between them and heaven." Tournefort relates, that in the island of Mycene the inhabitants seldom arrive at the age of twenty- one without becoming so. There are some races of people that have little or no hair on the surface of the body. The Mongolian, Chinese, and American have little or none upon the chin or chest. Hair varies considerably in shape, texture, and in all its mechanical properties. Instead of being cylindri- cal, it is sometimes flattened, striated, and deeply grooved, or even beaded. It also varies much in length, firmness, tenacity, and disposition to curl ; all which varieties depend on some corresponding differ- ence in the relative action of the vessels at the bull) or root. The human hair which is most esteemed in commerce, is about twenty-five inches in length ; and the more it falls short of this, the less value it bears. Its length and quantity is, in all animals, much inliti- enced by change of season and climate. Previous to» winter, the hair increases in length and quantity, and this increase bears a ratio with the temperature ; hence cattle and horses in farms near the level of the sea, have a shorter and thinner hair than those in higher elevations, where the temperature of the air is lower. The fur of animals, which is sought as an article of commerce, is thin, and would be less valuable if ob- tained during the summer than during the winter sea- son. The influence of climate is still more obvious. The dogs of Guinea, and African and Indian sheep* possess so little hair on the body, that they may be- almost said to be naked ; — the Siberian dog and Ice- and sheep are, however, protected by a very long and thick covering. The fleece of sheep in England is, entirely wool ; the Zetland and Iceland sheep, how- ever, in addition to wool, have intermixed with it a quantity of coarse and shaggy hair. In warm coun- tries the elephant and rhinoceros have scarce any lair ; on the contrary, the carcases of those discovered n the ice of Siberia, are found covered with a sort of wool mixed with long thick hair, very similar to the oat of the Iceland sheep. To accommodate them- selves to this change of season and climate, animals :ast and renew their hair, just as birds moult, or as lerpents and caterpillars cast their skin. Moles cast heir winter clothing generally before the end of June. The fleece of sheep, if allowed to fall, is generally cast Before the end of July. In some cases the nerves which supply the roots of the hair serve to extend the sense of touch ; thus the hairs which form the whiskers of the lion, tiger, and cat, being supplied with pretty large nerves at their roots, the slightest impression is com- municated from their joint to their base. It is the same with the whiskers of the seal. The hairs of he whiskers are moved freely at the will or pleasure jf these animals, which is not the case with the hairs ot the rest of the body, although under certain vio- 222 CUTANEOUS SYSTEM. lent emotions, fear, fright, or anger, they are observed to become erect. This is caused by a muscular web, which lies below the skin, and is called the panni- culus carnosiis, the fibres of which in contracting force the hair into an erect position. It is well seen in dogs and cats. It commands, also, the erection of the quills of the porcupine, and the spines of the hedge- hog. The colour of the hair of many quadrupeds, like the plumage of birds, changes at certain seasons of the year. The summer dress of the Alpine hare (Lepus variabilis] is of a tawny grey colour ; as winter approaches, it gradually changes until it becomes snow white. The ermine, which frequents the out- skirts of woods and thickets during summer, is of a pale reddish brown colour ; in August it becomes clouded with pale yellow, and in November it is snow white. As spring returns the white becomes mottled with brown spots, and in the month of May its sum- mer garb is resumed. The hair even of the human body is somewhat lighter in winter than in summer. WOOL is a cutaneous appendage which differs in no respect chemically from hair ; it is, indeed, gene- rally described as hair short and crisped. It differs, however, from hair, in being finer in texture and in growing more uniformly. Each filament of wool grows at equal distances, and if not shorn, all the fila- ments separate nearly at the same time from the skin, for the wool completes its growth in twelve months, and is then shed. Another peculiarity is the diffe- rent degree of thickness which prevails in the wool on various parts of the same animal, besides the fila- ments are closer at their extremities or points than at their roots. Furthermore, the fleece which grows during winter is of much finer quality than that which is produced during summer. The physical qualities, however, of wool, are considerably affected by the soil on which sheep feed. It has been shown by Mr. Bakewell that the herbage of each district derives from the difference of soil peculiar properties, which when taken as food, have the power of affecting that process of the animal economy by which wool is pro- duced. Accordingly, the wool of sheep pastured on chalk districts, or light calcareous soils, is hard and harsh to the touch ; the wool of those pastured on rich loamy argillaceous soils, is always distinguished by its softness. The soils most favourable to the soft quality are, first, the argillaceous, and next, the sili- ceous ; the calcareous, whether limestone or chalk, produces wools of a contrary quality ; so that in pro- portion as these earths preponderate in a loose state near the surface of different soils, their effect may be detected, whatever be the breed of sheep from which the wool is shorn. If the weather be fine, sheep in this country are shorn in the month of June, although some farmers delay the operation until July. The wool in the state first shorn is called fleece, and each fleece is usually separated into three sorts : 1, mother wool, or that of the back and neck ; 2, the wool of the tails and legs ; 3, that of the breast and under the belly. This classification corresponds with the Spa- nish method of sorting into rafinos, or prime ; finos, or second best, and terccras, or inferior sort. Till within a few years, the finest wool was imported from Spain ; but next to Spanish sheep, the Ej^lish yield the finest wool that can be introduced into the market. BRISTLES and SPINES are modifications of hair ; in the former the hair is stiff, in the latter inflexible. The bristles growing upon the back of the hog and wild boar form a considerable article of commerce, being extensively used by brushmakers, shoemakers, saddlers, &c. They are imported into this country from Russia ; those of Ukraine being held in the highest estimation. HORN is a substance analogous to hair, and has, indeed, been identified with it. When the horn of an ox is examined, it is found to consist of fibres which run parallel with each other from the root to the point of the horn, sweeping along the course of whatever curvature it may describe. Their disposition, how- ever, varies. Instead of being straight and sweeping, these fibres in the horn of the ram present a waved or undulated appearance. Hence the substance of horn appears to be made up of a conglomeration of hairs ; but this is not always the case, for the horns of the camelopard arid stag are truly osseous. It would appear, indeed, that horn differs from bone in this, that horn is composed principally of animal matter intermixed with very little phosphate of lime or other earthy matter, while bone consists principally of phos- phate of lime with very little animal matter. The density and compactness, therefore, of the horn, de- pends on the quantity of earth or animal matter en- 1 tering into its composition. The horn of the rhino- ceros is purely a cartilaginous or horny substance ; here the animal matter predominates ; the horn of deer is purely osseous, in this case the earthy matter predominates. Horns are in most animals to be re- garded as weapons of attack and defence ; and as such they are instinctively used ; hence young cattle are observed butting with their head months before their horns appear. The manner in which the horn is developed is as follows : immediately below the skin, and over the frontal bone, two tubercles may be seen in the young calf. These gradually become more callous, and en- large in size, shooting out conically. This growing horn consists of three parts, an external sheath or prolongation of the cuticle, a vascular investment, and an internal osseous substance. The vascular mem- brane has two different powers of production at each surface ; the internal supplies the phosphate of lime ; the external deposits layers of horny substance. When three years old, the horn is smooth and hand- some ; afterwards its annual growth is marked by a circle or wrinkle at the base ; and, according to the number of these, the age of the animal may be deter- mined. Horns, however, do not always grow from the frontal bone ; in the rhinoceros they proceed from the nasal bone, and in many other animals they arise immediately over the ridge of the occipital bone. In some species, as the stag, the male only has horns ; and, generally speaking, as in the case of the goat, where both male and female have horns, the female are smaller than those of the male. The horns, how- ever, of the bull are shorter and denser than those of the cow. Between the size of the horn and bulk of the animal there is no correspondence ; some small breeds of cattle have very large horns, while some good-sized cattle, as the Yorkshire-polled cattle-, have no horns at all. Horns vary remarkably in shape and size. The horns of the goat are rough, angular, and bent retrally ; those of the red deer are branched, round, and recurved. The roe possesses horns which are round and erect ; the fallow deer horns pal mated at the top. The length of the horn varies conside- rably. Cattle with long horns are said to excel in their hide, hair, and the quality of beef; those with short horns in the quantity of the beef, tallow, and CUTANEOUS SYSTEM. 223 milk they yield. The antlers of the stag, after re- maining nearly a year, are cast off and soon replaced. Immediately before this occurs the carotid artery is seen to throb, and all the vessels of the skin are turgid, the heat of the parts being much augmented. A tubercle is then observed below the skin, which gradually increases in size, as it becomes converted into bone. The cartilage being ossified, shoots up- ward in the form of a lengthened cylinder, which soon divides into branches. The skin being carried along with and investing the horn, forms what is called its velvet coat, but when fully formed, it shrivels and peels off, and the antler presents then a smooth and bare surface. The rapidity with which the vessels form the antler is remarkable ; an antler weighing thirty pounds is sometimes completely formed in the space of fourteen days. After being fully developed, the vessels at the base continue to deposit additional osseous matter, which is called the burr. The accu- mulation of this substance at length encroaches on the arteries, and by diminishing their capacity for con- taining blood, gradually cuts off the supply of nourish- ment. The antler is then nourished only by its own internal vessels. These at length shrink and become obliterated, and the horn then adheres to the head only as a foreign body. In the mean time the absorbent vessels under the base of the horn, scoop a. groove between the living and the dead matter, so that the antler, deprived of support, falls upon the slightest concussion. Thus are these graceful appen- dages to the figure of this animal annually cast and reproduced. BEAKS, NAILS, CLAWS, SPURS and HOOFS, are of the same composition as horn, consisting principally sf gelatine with only a trace of earthy matter. The horny substance of the beak differs from horn in its colour not being so fixed. The colour of the bills of many birds varies with the season, and changes also after death : the colour of the horns of cattle is per- manent. Nails differ from horn only in not being tubular, but deposited in flat plates. They occur in the toes of quadrupeds, birds, reptiles, and pass into claws. Spurs occur chiefly in gallinaceous birds ; they are softened by heat, and may be easily bent into particular shapes. Hoofs are peculiar to herbi- vorous animals, forming a solid base and protection to the foot. FEATHERS, which are the characteristic appendages to the cutaneous system of birds, form a covering which not only protects them from the inclemencies of the weather, but winch, when large, as in the wings and tail, serve as instruments of motion. The struc- ture of a feather is exceedingly curious. Each feather consists of a tube or barrel, from which proceeds the shaft or stock, on each side of which are affixed barbs or flat filaments tapering to a point. The tube or barrel takes its rise like hair in the tissue immediately below the cutis vtra, and passes by a tubular opening through the other layers of the skin, which are so folded downwards and inwards as to form a sheath, which invests the bulb or vascular part of the feather. The tube or barrel is a hollow, horny, transparent cylinder, consisting of two layers, an external and an internal. The external is a circular plate, exhibit- ing linear impressions which run round the barrel in a transverse direction ; the internal consists of fibres running longitudinally. It is largest in anserme and gallinaceous birds, as the turkey, swan, goose, &c., for which reason the quills of these birds are best adapted for making pens. By being formed into a hollow cylinder, the barrel of the feather is rendered stronger, lighter, and more capable of resisting flexion, than it otherwise would be. Its cavity indeed in some birds of flight, as the condor, eagle, and hawk, is continued some way into the shaft, and is, like the bones of the skeleton, filled with air, which enters into it during respiration through a minute orifice at the extreme point or end of the quill. Within the barrel is a dry jointed membranous substance, which is the remains of the vascular pulp which originally contributed to the growth and nourishment of the feather. The shaft which is prolonged from the barrel consists of a cuticular layer, disposed likewise in a circular and longitudinal direction, the central portion of which is filled with a pithy substance like cork. Its outer surface is slightly convex, its inner nearly flat, with a groove running along the middle. From each side of the shaft proceed the barbs, which are placed with their flat sides towards each other, whereby a power of resistance is derived which enables them when flying to encounter the impulse and pressure of the atmosphere. They derive this power of resistance, says Dr. Roget, from the flattened shape of these filaments, which allows them to bend less easily in the direction of their flat surfaces than in any other, in the same way that a slip of card cannot easily be bent by a force acting in its own plane, though it easily yields to one at right angles to it. Now it is exactly in the direction in which they do not bend that the filaments of the feather have to encounter the greater resistance and impulse of the air; it is here that strength is wanted, and it is here that strength has been bestowed. But this is not all : in birds of flight and water birds, the barbs are.by their adhesion to each other, rendered firm, and this is effected by a very curious mechanism. When viewed under the microscope, a number of minute fibrils or processes are seen arranged along the margin of the laminae, so curved as to interlace with or clasp one another whenever they are brought within a certain distance. Those fibrils which pro- ceed along the side of the laminae in the direction from the quill and to the extremity of the feather are long, flexible, and bent downwards ; those which proceed from the adjacent lamina, from the extremity of the feather towards the quill end, are shorter, firmer, and turn upwards, so that when the long fibrils are forced far enough over the short ones, their crooked parts fall into the cavity made by the crooked parts of the other, just as the latch that is fastened to a door enters into the cavity of the catch fixed to the door-post, and there hooking itself fastens the door. These little teeth, like processes or barbules, are wanting in feathers not intended for flight ; hence they are not found in the feathers of the ostrich, nor do they interclasp each other in the manner above described in the feathers of the peacock's tail, nor in those placed around the ear of the owl. The feathers of nocturnal birds of prey have the barbs covered with long silky down, whence, it has been observed, arises the slow and silent flight of these birds. The mode in which feathers grow or become deve- loped has been attentively examined by several natu- ralists, especially by M. Cuvier, whose memoir in the Memoires du Museum, torn, xiii., comprehends almost all that is known on this intricate subject. On quit- ting the egg, the body of every bird is found covered, excepting the under part of the belly, with a sort '224 CUTANEOUS SYSTEM. of down consisting of minute filaments collected in tufts, which are implanted in a bulb or follicle which contains the sheath of the feather. When the sheath protrudes through the skin it has the appearance of a thorn or little cone, within which may be observed the medulla or that central gelatinous cord which may be considered to form the different parts of the feather. Upon its protrusion the tufts just described generally fall off, excepting in the eagle, vulture, and other rapacious birds, to the feathers of which it re- mains attached for a considerable time resembling fine down. From the medulla or pith the barbs are first discovered proceeding from it in very delicate and thin filaments ; then the shaft or stalk of the feather makes its appearance, to which they soon become attached ; the whole being enclosed within the sheath, the barrel end of which is filled with a glairy fluid. In proportion as this fluid becomes converted into the barbs and shaft, the central cord withers and corrugates. The sheath is at length burst open, and the medulla appears encircled by the barbs and shaft. These parts being formed, the re- maining part of the medulla becomes enveloped with the matter of the quill which is a continuation from the shaft. The quill therefore is the last part formed, and continues to increase in length for some time after the full growth of the barbs and shaft. When feathers have reached their full growth they become dry, and only the tuber or medulla within it continues to absorb moisture at its termination or bulb. It gradually, however, ceases to receive this nourish- ment ; its attachment to the skin then becomes loosened ; and the feather is cast, and again in the manner described renewed. This periodical change of plumage is termed moulting-, during which period inrds generally become sickly and much debilitated. Immediately below the feathers of aquatic birds, in the region especially of the chest, other small and very delicate feathers are found which are called down, which serves to protect the body from the action of the water, and which, not being good con- ductors of heat, likewise preserve the temperature of the body. The down of the eider duck is esteemed the most, valuable. These birds pluck it from their breasts to line their nests with it. So elastic is it that a quantity weighing only three quarters of an ounce will spread over a larger surface than the crown of the greatest hat. That found in the nest, which is termed live down, is much more elastic than that plucked from the dead bird, and is more highly esteemed. The colour of the plumage of birds varies exceed- ingly, being in many species, especially in tropical climates, of dazzling brilliancy. The iridescence of the plumage is referable to the same cause as the colours of very thin plates, which has been explained in the article COLOUR. It is, however, remarkable that the colour of the plumage of certain birds under- goes a change at different seasons of the year. Among aquatic birds, the black guillemot ( Una Grylle] is of a sooty black in summer, with a patch of white on each wing ; as winter approaches, the black gra- dually disappears, until the plumage becomes white, mottled with ash-coloured spots. Again, the ptarmi- gan or mountain grouse (Tetrao lagopus) has an ash coloured plumage, which, however, changes in winter to a snow-white ; a providential change, says Mon- tagu, for, were the surface of the ground not consonant with their colour, few would escape the searching eye of the falcon or the eagle in the lofty and exposed situations they are found to inhabit. It has therefore been wisely ordained that the young first appear, like their parents, in a mottled plumage, similar to the lichen-covered rocks they frequent, and continue in this dress till the approacii of winter, when old and young become equally white as the surrounding snow. In the Scottish Highlands this change commences about the month of September ; large patches of white appear on the feathers of the wings and back ; these extend, and in the month of January the bird is of a pure white. The return of colour commences by the appearance of black spots, which enlarge ; they become of a brownish hue, until the colour and the summer plumage is com- pletely resumed. This change of colour is, however, sometimes limited to a certain part of the body. Thus the cheeks and throat of the little auk (Ak-a alle) are black in summer, and become of a dirty white in winter ; the head of the black-headed gull (Larus ridibundus}, as the name indicates, is black in winter, and becomes white in summer. SHELLS and CRUSTS are a part of the cutaneous system of the Crustacea, besides which they occur to several of the annelides, as the serpulaand dcntalium. They consist simply of layers of earthy matter inter- posed between membranes of animal matter. This deposition takes place between the epidermis or cuticle and the cutis vera or true skin. It occupies the place of the rete mucosum above described. Crusts differ from shells only in being more brittle, in consequence of being composed of a greater quantity of earthy matter. In shells the carbonate of lime predominates ; in crusts there is also a considerable portion of phosphate of lime. The size, texture, shape, and colour of shells, display an infinite variety. The shield of the snail is semi-transparent and elastic, the shell of the volutes opaque and hard as marble. River shells are not so diversified in form and colour as land and sea shells ; but so numerous and varied are the characters of shells, that their study and classification constitutes, under the term CONCHOLOGY, a complete department of natural history. The crusts of the Crustacea like the hair of quad- rupeds, or feathers of birds, are cast periodically, and when injured or destroyed are easily renewed. When this change occurs in the lobster, his shell grows soft, the sutures open, and the claws burst at the joints. Thus loosened, the animal, by a trembling motion, or sort of spasm casts off his case, and then retires in a state of nakedness to the hollow of rocks. The re- leased body then makes a sudden growth, and in about eight and forty hours a fresh concretion of humour is deposited over the whole surface of the body, which soon hardens into a crust, which is adapted in every part to the increased size of the animal. This change takes place annually. Besides in the Crustacea, pro- perly so called, crusts occur in certain insects, echino- dermata or sea urchins, and starfish. Lastly. SCALES are the cutaneous appendages or covering proper to fish ; they are found also in every part of the body of certain reptiles, and also upon the feet of birds. They are composed of the same matter as the cuticle which extends over them ; and they vary considerably in size, form, colour, and relative position. Such are the appendages, which constitute a part of the cutaneous system of the different classes of animals which inhabit the earth, the air, and the waters ; and which afford a protection adapted in the C Y A M U S — C Y C A D E JE. 1225 best possible manner to their different and individual exigencies. CYAMUS (Latreille). A genus of crustaceous animals belonging to the section Edriophthalma and order Lasmodipoda, and having for its type a curious species, which is found upon the bodies of living whales, being the Oniscus ceti of Linnaeus. This genus consti- tutes a distinct division in the order to which it belongs, to which Latreille has given the name of Ovafia, oval bodied, in order to distinguish it from the other divi- sion of which CAPRELLA (which see) is the type, and which is remarkable for the long and slender form of the body. These animals were considered by M. Savigny as being nearly allied to the Pi/cnogonida, and forming with them the passage between the crus- tacea and arachnida. The body is composed of a small somewhat oval-formed head and six transverse segments, the abdomen being very minute and rudi- mental. The head is furnished with two moderate sized and two minute antenna?, with an oral apparatus, concerning the various organs of which authors are somewhat at variance. At the base of each of the smaller antennae is a small depressed cup-like spot covered with a membranous substance, and which has been regarded as the organ of the sense of hear- ing. The eyes are two in number and granulated, although Savigny calls them " yeux lissees," whilst the yeux composees, which he mentions between the antennae, are not discernible. The legs, or the limbs representing those organs, are of varied form, the first pair being slender and terminated by a claw and a moveable ringer, the second, fifth, sixth, and seventh pairs are greatly dilated and terminated by a large joint, and a moveable recurved finger ; but the most ' curious portions of the animal are the organs repre- senting the third and fourth pairs of legs, and which consist in two or four pairs of long and slender ap- pendages, which have been considered to be organs of respiration ; these are, moreover, furnished on the underside of the body of the females with four large plates serving as a pouch for the reception of the eggs. We are indebted to M. Rousse! de Vanzeme (whose memoir upon another whale parasite, Cetochilus australis, we have in an article upon that genus noticed,) for the most complete account hitherto published of this curious group of parasites, and which were ob- served by him in his voyage to the whale fisheries in the Southern Ocean. Previous to the publication of his memoir in the Annales des Sciences Naturelles for May 1834, one species only had been described, although Latreille in the Regne Animal had men- tioned the existence of two other species inhabiting the Indian seas and the ocean near the Cape of Good Hope. M. Roussel, however, not only distinctly de- scribed three species living upon the whales of the Southern Ocean, but also observed their respective habits. Sometimes these creatures are so abundant upon the whales, that the infested animals can be easily recognised at a very considerable distance by the white colour which they impart to the whale, and which is visible when it rises to the surface. When these parasites are removed the surface of the body is found to be deprived of the epidermis, and as it were corroded. They are ovoviviparous, producing eggs which are received into and hatched within the pouch- iike plates on the undersides of the centre of the body, at times eggs alone, at others both eggs and young, and at others young only being observable in NAT. HIST. — VOL. II. the pouch. Cyamus ovalis and gracilis are stationary, being found in great numbers agglomerated upon the corneous eminences of the SaUena mysticetus. C. erraticus is, however, organised for its wandering habits, being of a slender form and with stronger legs serving for prehension. The young ones appear with all the characters of their kind, only the head is rather large, and the supposed branchial appendages instead of being long and slender are short and some- what globose ; the females of C. ovalis cover their young with their bodies, whilst those of C. eiraticus abandon their young conformably to their own mode of life ; and in C. gracilis the females, males, and young are all found mingled together. CYANELLA (Linnaeus). A bulbous genus from the Cape of Good Hope. Linnaean class and order : Hexandria Monogynia, and natural order Asphodelcee. Generic character : corolla of six-spreading unequal petals, inner ones longest : stamens below the ger- men ; filaments united on a fleshy cup at the base ; anthers erect, five are equal, bursting at vertical pores ; the sixth twice the size, and oblong. Style declining ; capsule three-celled, three-valved, and many seeded. The flowers of this genus are of various colours, handsome and sweet-scented. The plants are kept in a pit or frame, or may be planted in front of a hothouse, where they will succeed if defended from frost. CYANITE, a mineral which derives its name from a Greek word, indicative of its sky-blue colour. When pure, it is idio-electric, as some crystals by rubbing acquire negative electricity, — and others with a similar surface positive electricity : hence the name disthene, given by Hauy to this mineral on account of its double electrical powers. It occurs massive, and disseminated ; and is sometimes regularly crys- tallised. The primitive figure is an oblique, four-sided prism. It is found in various parts of Europe, Asia, and America. The Shetland Islands produce some very beautiful specimens, and it is readily distin guished from actynolite by its cleavage and infusi- bility. CYANUS. Is the Centaurea cyanus of botanists a common plant in corn-fields, provincially called blue-bottle. CYATHEA (Smith). A West-India fern, of tree- like stature, and highly ornamental. It was described as a SpJuBroptcris by Bernhardi and Wallich, and Peranema by Don. C YBI (JM, a genus of spinous-finned fishes, belong- ing to the mackarel family, SCOMBKROID^E, which see. CYC ADE^,— the Cycas family. A natural order of dicotyledonous monochlamydeous plants, contain- ing two genera, and nearly thirty known species. Much difference of opinion has existed among bota- nists as to the particular situation which this order ought to occupy in the natural system. By some it has been included in the monocotyledonous or endo- genous class of vegetables. In so doing these authors have laboured under an obvious misapprehension as to the real structure of the cycadeae. The order may be said to have a nearly equal relation to the flower- ing or flowerless plants ; agreeing with the former in the presence of the sexes and the completeness of the vascular tissue, and with some of the latter, such as ferns, in the peculiar gyrate vernatim of the leaves, and the imperfection of the spiral vessels. By Lind- ley, Cycadcce are included along with Con/feres under a section of vascular plants, to which he has applied 226 C Y C H R U S. the name Gymnosperma:, and which are distinguished by the seeds being naked, and the vessels of the wood having large apparent perforations, to which nothing similar is seen elsewhere. This order was by some botanists in former times included under the fern tribe, in consequence chiefly of the mode in which the leaves are developed. Lin- naeus originally considered it as belonging to the palm tribe, to which it appears at first sight to have an affinity in its large 'pinnated leaves, and simple cylindrical stem. It differs, however, totally from palms, in being dicotyledonous, and in having an essentially exogenous stem, a gyrate vernatim and naked seeds, which grow on the margin of a contracted leaf. The order to which Cycadece bears the closest resemblance is Coniferts, or the pine tribe. With this order it agrees in the structure of its seeds, the form of its inflorescence, the arrangement of the veins of the leaves, the imperfect development of spiral ves- sels, and the apparent perforation of the vessels of the wood. The essential characters by which the order is dis- tinguished and separated from all others are : Flowers naked, dioecious, terminal ; sterile flowers monan- drous, collected into cones, each floret consisting of a single scale or anther, bearing the pollen on its under surface in two-celled cases ; fertile flowers, either col- lected into cones or surrounding the central bud in the form of contracted leaves without pinna;, bearing the ovules on their margin ; ovules solitary, naked, with no other pericarp or covering than the scales or contracted leaves upon which they are situated ; seed with a horny integument; albumen Hesav. solid; embryo inverted, the radicle being next the apex of the seed, from which it hangs by a long1 stalk or funi- culus with which it 1ms an organic connection. The plants belonging to the order are trees with a cylindrical undivided trunk, increasing by the deve- lopment of a single terminal bud, ancl covered with the scaly bases of the leaves, which are pinnated, with a gyrate vernatim and parallel veins. They are na- tives of tropical regions, and are found in America and Asia. They also grow at the Cape of Good Hope, 'and in Madagascar. In general they possess mucilaginous properties. The genera ol the order are cycasand Zamia. Cycas circinalis, broad-leaved cycas, is a native of the East Indies, especially the Molucca Islands, where it attains a height of fifteen or twenty feet. The tree is called Indu by the natives. Its trunk is covered with the scars whence the old leaves have fallen, and from the top of the stem grows a crown of most beautiful foliage. It bears a drupaceous, smooth, reddish, orange fruit about the size ot a walnut. The outer pulpy portion is about half an inch thick, and surrounds the inner horny Coat, which covers a beau- tiful membranaceous lining of a rich brown colour. The tree was introduced into Britain by the Earl of Clarendon in the year 1700. It is very ornamental in our green-houses, but requires much space for the full display of its leaves. The fruit of the tree, is used in India as an article of food. From the soft centre of the stem a fari- naceous substance is procured in many respects simi- lar to the sago obtained from the sago palm. In preparing this substance, the stem is cut into pieces, several feet long, which are afterwards split longitu- dinally, so as to expose the pith ; this is taken out, mixed with cold water, and then beaten with a wooden pestle in a large mortar or trough. The mixture, after being allowed to stand for some time, gradually deposits 'a sediment, which is easily separated by decantation. This substance which may be denomi- nated spurious sago, is merely the starch contained in the pith. The nuts after being dried for a month in the sun, are beaten in a mortar, so as to separate the kernels, which are afterwards made into a kind of flour : much used by poor people in India as a nutritious article of diet, and called by them Indum podi. In some Catholic countries the leaves or this plant are carried in procession, and used to adorn temples on Palm Sunday, in place of those of the date palm. Cycas rcvoluta, revolute-leaved cycas, is a native of China and Japan, where it attains the height of five or six feet. It produces leaves four or five feet in length, which crown the trunk and form a magnificent basin ten or twelve feet broad at the base. The tree produces an orange-coloured drupe, nearly as large aa an apricot, containing much white transparent muci- lage, and enclosing an oval-shaped nut. The fruit has a mealy sweetish taste, and is eaten by the Ja- panese. From the pith of the young stem of this species also, a kind of sago is procured, which is highly esteemed in the countries where the tree grows. The plant is cultivated in stoves in this country, into which it was introduced in 1799. Cycas inermis is another species found wild in China, where it is also much cultivated for its beauty. Its trunk is five feet high, and it bears an egg-shaped fruit of a red colour. In Tonquin, a valuable sago is made from the pith. The genus Zamia resembles the last in many re- spects. It includes upwards of twenty species. Zamia spiralis, yields large nuts, which are said to be eaten roasted by the natives of New South Wales. Zamia cycadis, bread-tree Zamia, is a native of South- ern Africa. By the Caffres and Hottentots the pith of the tree after being buried in the earth for some time, is made into cakes which are used for food. CYCHRUS (Fabricius). A genus of coleopterous insects belonging to the section Pentamera and family CdrabidfE. These insects are of a moderate size, having the body robust and destitute of wings, the upper lip notched, the upper jaws long and rather slender, the maxillary and labial palpi with the last joint large and spoon shaped, the tarsi are alike in both sexes, and the body is much narrowed in front. They are generally of a black colour, and are found under the bark of decaying trees, and beneath moss and dry leaves lying at their roots, more especially in mountainous regions. They appear exclusively to inhabit Europe, Asiatic Russia, and North America. Dejean describes nine species, but there is only one indigenous to this country, namely, the Ro&tratus of Linnasus, a species having so much resemblance to some of the darkling beetles (Melasoma] that Linri&us' was misled as to its true relationship with the Carabi, and placed it in the genus Tenebrio. The robust structure of the mouth, however, and especially the great development of the palpi, prove that its habits are not less ravenous than the remainder of the family to which it belongs. It is found not uncommonly in the spring under dead leaves in the woods and com- mons near London, and is about three quarters of an inch long, and of a black colour, the elytra having a granulated appearance. It owes its specific name to CYCHLA— CYCLOPS. '227 the front of the head being elongated into a kind of beak. Two other species, C. elongatus and attenuatus, have been mentioned as inhabitants of this country, but without sufficient authority. CYCHLA, a genus ofspinous-finned fishes, belong- ing to the family LABROID^E, which see. CYCLAMEN (Linnaeus). A genus of European tuberous rooted herbs, cultivated for the beauty of their flowers. The genus belongs to Pentandrin Monogynia, and to the natural order Primulacecc. Generic character : calyx bell-shaped, divided half way down into five parts ; corolla base swollen, throat a little prominent, segments of the limb reflexed ; stamens borne on small filaments inserted in the tube ; anthers connivent and arrow-shaped ; style filiform and protruding ; seed-vessel a berry, but opening at last into five parts ; seeds seated in the pulp. These plants were called sow-bread by the ancients, in allu- sion to the tubers being sought for and eaten by hogs. The Persian is the only greenhouse species, but all deserve to be kept in pots, and placed where they may be seen to most advantage. They yield abund- ance of seeds by which they are easily increased, provided the seed is sown soon as it is ripe. CYC LAS (Lamarck), TELLINA (Linnaeus). This genus of molluscs has been separated from the genus Tcllina, in consequence of certain well-defined distinc- tion: these, nevertheless, though sufficient to separate them from that genus, have led to some speculation on the part of modern malacologists ; and we find in tho French school that the genus Cyrena of Lamarck, the genus Cornea and Corbicula of Megerle, and the Galaihea of Cuvier, are all considered as subdivisions .of the genus Cyclas ,• and though we do not advocate an useless multiplication of genera, we cannot alto- gether agree with that arrangement ; however, as the general habits of these molluscs, as well as their organisation, nearly correspond, we give the following description in accordance to the French school : — The shells of this genus are small, of a very convex oval form ; valves very thin, and always without three primary teeth on either of them ; apices never eroded or decorticated ; some species are so thin and fragile as to be transparent ; the valves smooth or transversely striated ; shell transverse, equivalve, apices protuberant ; primary teelh very small, almost obsolete, sometimes two on each valve, of which one is plaited in the middle of the one valve, and some- times two plaited or folded teeth on the other. These constitute Lamarck's genus Cyclas. Such species as have a suborbicular form, the cardinal teeth rather variable, and always very small, if not altogether ob- solete, with the apices not eroded, form the genus Cornea of Megerle. The species of a subtrigonal, or an elongated oval shape, having the apices eroded, and more anterior, with three cardinal teeth, the two posterior of which are bifid, constitute Lamarck's genus Cyrena, and those having the lateral teeth dentated, but corresponding in other respects, form the genus Corbicula of Megerle. The species of a subtrigonal form, with two-grooved cardinal teeth on one valve, three on the other, the middle one being larger and callous, form Lamarck's genus, Galathca. All these molluscs inhabit fresh water, generally buried in the mud ; the two last sections only are known in Europe : the greater number of the others being from the Indian rivers, but every part of the world presents species of the first division; the shells are generally provided with an epidermal coat. The animal has its body of an oval form, the edges of the mantle plain, the tubes short and united, the foot large, compressed at its base, and terminated by a species of foot, or appendage answering that pur- pose. This genus is classed in the third class Ace- phalophora, third order Lamellibranchiata, eighth family Conchacea. CYCLICA (Latreille). An extensive division of coleopterous insects belonging to the' section Tetrn- mera, distinguished by the generally short and rounded form of the body. They differ from the Rkyncophora or weevils, in not having the head produced into a rostrum ; from the Xyhphaga, by having the antennae not clavate ; from the Platysoma, by the body not being flattened ; from the Longicornes, in the antenna; being shorter than the body ; and from the Eitpoda, in having the hinder part of the thorax as wide as the base of the elytra. For the particular characters of this division as well as for an account of the families of which it is composed, we must refer to our article headed CHRY- SOMELID.^, where, in consequence of this division nearly corresponding with the Linnaean genus Chry- somela, we have thought it more convenient to give a description of this group. CYCLOBRANCHIATA is the name given to an order of molluscs having the organs of respira- tion branchial, in the form of tufts, more or less deve- loped, symmetrically arranged near the vent, which is situated in the median line of the posterior part of the animal's body. The skin is naked, though some- times intercalated. This order includes the genera Don's, Onchidoris, and Peronia ; of the second class, Paracephalophora. they will be described in their respective places. CYCLOPS (Muller). A genus of minute aquatic crustaceous animals, considered by M. Edwards as entitled to the rank of an order, to which he has given the name of Copepodd. These little creatures, which abound in fresh and standing waters, are seldom more than one-eighth of an inch long, and may constantly be observed jerking about by the assistance of their long tails. In their forms they somewhat resemble a lobster in miniature, the thoracic part of the body being of an oval form, furnished with a single eye in front (whence the generic name of the group). This part of the body is divided at its hinder part into several segments, which are succeeded by an articu- lated tail or abdomen, from the base of which in the females depends on each side a large membranous bag containing the eggs. The abdomen is forked at its extremity, each division being furnished with strong setae ; the upper antennas are very long and multiarticulate, but the inferior are short and four- jointed. The legs, which are very short, consist of five pairs, each leg being divided into two cylindrical branches. From their curious forms, great agility, and odd motions, these little insects form conspicuous objects in the exhibitions of the solar microscope, with which instrument so much instruction and amuse- ment is capable of being produced. The upper and long antennae perform the offices of legs, and the lower pair of these organs, from their being kept in a continual rapid motion, produce a kind of whirlpool, which brings into its vortex the minute particles upon which they feed. At the period of coupling the males are extremely active. The eggs which are of a brown, blue or green colour, varying according to their age, become transparent when nearly readv to P'2 228 C Y C L O P T E R U S — C Y C L O S T O M A. produce the young ; and it is an extremely curious circumstance, which has been well confirmed, that a single act of impregnation is sufficient for several successive generations, A female cyclops in the space of three months gives birth to not less than ten distinct broods ; and if we calculate only eight broods, each having only forty young, it will be seen how immense must be the increase of these creatures. The duration of the egg state varies from two to ten days, according to circumstances, such as the degree of temperature, the period of the year, &c. When hatched, the young have only four legs, with the body of a rounded form, and destitute of tail. Muller, the celebrated Danish writer upon these and other allied animals, not knowing them to be the young of the cyclops, formed them into a distinct genus with the name of Amynionic. Shortly afterwards they acquire an additional pair of legs, and these for the same reason were formed by the same author into the genus JVauplius. After the first shedding of their skin they are said to possess all the organs of their perfect form, but of a diminished size, especially as regards the antenna; and legs ; and that after the third moulting they become adult ; but in this manner of reckoning it will follow that two pairs of legs must be developed without a corresponding moulting having taken place, and this is so contrary to what is observed amongst the invertebrated animals that the correctness of such observation may perhaps be questioned. The chief food of these animals consists of minute particles of animal matter floating in the water, but in default of this they will feed upon vegetable substances in a decaying state. When one of the antennae is cut oif no change at first takes place, but at the following moulting the loss is repaired by the production of a new antenna. There are numerous species belonging to this group, of which the Monoculus (juadricornis of Linnreus (a name improperly changed by Dr. Leach to C. vulgaris) is the type ; it is very variable in its colours, being sometimes reddish, at others green, bluish, or whitish. It is a very common species. Some of the species (forming the genus Calanus of Dr. Leach, including the C.finmarchianus of Muller,) have the inferior antennae obsolete, whilst others (forming our genus Cunthocampus, having for its type the C. sta- jihylinus,} have the abdomen of the females recurved with a spine beneath at the base, and in some there is but a single egg-pouch (forming our genus Diapto- mus\ and of which the C. caslor is the type. CYCLOPTERUS, a genus of soft-tinned fishes, belonging to the order with the ventral fins under the pectorals, and to the third family of the order Disco- hales, and including the lump-fish and some others. The following are their most remarkable generic characters : — The rays of the ventral fins are dispersed all round the lower part of the thorax, and united by a single membrane of considerable strength into a concave oval disc, which the fish employs as a sucker for attaching itself to the rocks. This is their most remarkable character ; and it is from it that they get the name of Cyclopterus, or fin all round. Their other characters in brief are : the mouth very large, with small pointed teeth in both jaws, and also in the pha- rynx ; their gill lids small, their gill flaps with six fays ; their pectorals very large and united below the throat so as to unite with the disc formed by the ven- trals ; their skeleton is soft and very imperfectly ossi- fied ; and their skin viscous and without scales, but powdered over with small hard grains. Their stomach is large with numerous caeca ; their intestine and air bladder of mean size. They are usually divided into two sub-genera, the chief distinction being the form of the dorsal fin. '1. LUMP FISHES. These have a first dorsal fin more or less visible, but always very low and with simple rays ; the second dorsal has the rays articu- lated, and is placed immediately over the anal fin , the body of these fishes is very thick and clumsy, and also very soft, and not very manageable in the water ; but they are enabled to hold on upon the rock* by means of the ventral disc, and thus catch the food which is brought to them by the current of the water, and the}' are much less liable to be injured by the current beating them against the rocks than if their bodies were of firmer texture. COMMON LUMP FISH (Cyclopterus lumpus). This species is common on all the coasts of the British islands, and in most parts of the North Seas. The back is sharp and raised, the belly flat, the body of the fish deep, the dorsal and anal tins short, and the sides marked with rows of osseous tubercles. The length is usually about eighteen inches ; the colours — dusky on the back, and rerifice at the side of the gall. These gall insects are nuch subject to the attacks of a parasitic group o. lies, of nearly the same size, belonging to the family ,'halcidida;, and having the ovipositor long and ex- erted, their colours being highly metallic and beau- iful ; they compose the genus CaU'mimne. One of the species of this genus is employed in Greece in a very serviceable manner for hastening he maturity of the fig. This species, which is the Cynips pseties, deposits its eggs in the seed vessel of his plant, and the inhabitants place a quantity of the ;arly figs which had been attacked in the neighbour- iood of the more tardy ones ; so that the insects when quitting the former, covered with the fecunda- ory dust, introduce themselves into the latter, so as :o cause the more speedy ripening of the fruit. This irocess is termed caprification. Hitherto all the species of this family have been :onsidered as inhabiting galls, but in a memoir which he author of this article has lately published in the Mdgazine of Natural History, we have given the history of a species which we discovered to be parasitic upon the aphides of the rose, in which respects it forms an interesting point of connection between such of the IcIi)winin>nidiE,zs the Ap/iidius,(sec BRACONID^E,J and the true gall-flies. Oak-apple gall and Cynips qnercusfolri. The family comprises the genera Cyrtvps, F'>gitcs, Ibaiut, Anncharix, and a few others, which we have proposed in the memoir above referred to ; these genera rest chiefly upon structural differences. The typical genus, Cynips, has the abdomen compressed and the antennae filiform ; the submarginai cells are three in number. The oak-apples are produced from one of the species of this genus, Cynips quernts- folii, and the bedeguar, (which see,) is the result of (he wounds of the Cynips roscc, a species of moderate size, of black colour, having the legs and abdomen, except, at the tip, red. CYNOGLOSSUM (Linnaeus). A genus of herbaceous herbs, mostly biennials, and natives of Europe. Two of the species are British, and called, from the shape of the leaves HauniFs-tongne. It be- longs to the fifth class and first order of Linnaeus, and to the natural order Boragincce. The cynoglossums are used as open border flowering plants, but do not possess much beauty. They are increased by seeds. 282 CYNOSURUS-CYPERACE^E. CYNOSURUS (Linnaeus) is the dog's-tail grass of British farmers, and a useful grass both in meadows and pastures, and when prevalent enhances the value of hay. CYNTHIA, (Fabricius). A handsome genus of lepidopterous insects, belonging to the section Diurna, and family NymphalidcE, having the wings scalloped, the anterior triangular, and somewhat hooked ; the antennae have an abrupt, short, terminal club ; the larva is spinose, and the chrysalis orna- mented with golden spots, and of an angulated form. The only British species is the Papilio cardui of Linnaeus, termed the painted lady ; it is of a rosy buff colour, with black and white markings, the lower •wings being marbled beneath, with four eyelets ; the larva feeds solitarily upon various kinds of thistles, nettles, &c. beneath a silken web ; the chrysalis is of a greyish colour. It appears in the spring, and again in August, but its appearance is very irregular, several seasons intervening before it is again met with. This is one of those species which with certain trifling alterations are met with in almost every quarter of the globe, CYPELLA (Herbert). A bulbous-stemmed her- baceous perennial, introduced into this country from Buenos Ayres. It belongs to Iridece. This bulb requires to be planted in a warm border, where it flowers and ripens seed in summer, but should be protected from frost in winter. CYPERACEjE— the sedge family. A natural order of monocotyledonous or endogenous plants containing nearly thirty genera, and between four and five hundred known species. It bears a strong affinity to Graminece or grasses, and by superficial observers would at once be referred to this family. It differs, however, in its solid and angular stem, in the absence of a diaphragm at the articulations, in the flowers being covered by a single bractea, and in the embryo lying at one end of the albumen, within which its cotyledonary extremity is included. In its general habit this order is also allied to Junceee and Restiacece. Its essential characters are : flowers hermaphrodite or unisexual, each with a glume or chaffy scale ; perianth either wanting or resembling bristles, rarely membranaceous ; stamens hypogynous, definite, generally three ; anthers fixed by their base, entire, two-celled ; ovary one-seeded, often surrounded by bristles ; ovule erect ; style single, trifid, or bifid ; stigmas undivided, occasionally bifid ; fruit a crusta- ceous or hard nut ; albumen of the same figure as the seed ; embryo lenticular, undivided, enclosed within the base of the albumen ; plumule incon- spicuous. The plants belonging to the order are herbs with fibrous roots, angular stems generally without joints, sheathing leaves, the sheath being entire, and spirate glumes, the lowermost of which are sometimes empty and sterile. They are extensively distributed all over the globe, and are found growing in marshes, ditches, and streams, in woods and meadows, on the sands of the sea-shore, and on the tops of mountains. In the northern regions, cyperacese are numerous, and bear nearly an equal proportion to the true grasses, but as we approach the equator the number of the species diminishes much, and at the same time the character of the genera becomes changed. By some authors the order has been divided into four sections : — I. The true Cyperacea;; II. Scripea;; III. Sclcrina: ; IV. Caricincc. The chief genera are, Cyperus, Scirpus, Sclerina, Carex, Uncinia, Schcenus, Rhynchospora, Eleocharis, Cladium, Mariscus, Erio* p/torum, and Kyllinga. The plants of this order possess in general mucila- ginous and demulcent properties, but they are not much used in medicine. They are not celebrated for their nutritive qualities, and are scarcely eaten by cattle. In these respects a wide difference exists between them and the grasses. They are by no means ornamental, and are not used in agriculture. In some sandy districts they are useful in binding the soil. Of the genus Cyperus, whence the name of the order is derived, there are 287 species already de- scribed, and of these only two are natives of Britain. Most of the species are tropical, and their number gradually diminishes as we recede from the tropics. Some of them yield tubers which are esculent. The root of Cyperus longus, sweet cyperus or English galingale, has an agreeable aromatic odour and an astringent bitter taste, and has been used as a tonic and stomachic. Cyperus rotundits, a native of the south of Europe and Asia, produces bitter tuber- ous roots about the size of a nut, which are said to be employed successfully by the Hindoos in cases of cholera. On account of their fragrance they are used in Greece to keep away insects from clothes. The tubers of C. perennis, after being dried and powdered, are used by the Indian ladies for scouring and per- fuming their hair. The root of C. odoratm has a fragrant odour and a warm aromatic taste. C. hydra is a troublesome weed in sugar plantations in the West Indies. The tubers of C. esculcnhts have an agreeable sweet taste, and are eaten in Spain, Italy, and Egypt. They consist of starch, fixed oil, sugar, albumen, gum, malic acid, vegeto-animal matter, and a substance analogous to tannin, various salts of potash and lime, and some oxide of iron. The starchy matter constitutes the chief portion of the root. The fixed oil which has an amber colour, and a slightly aromatic taste, forms a sixth part of it. In Germany the tubers when roasted are used as a substitute for coffee. C. papyrus is interesting on account of being the plant which yielded the papyrus of the Egyptians, whence the English word paper is derived. This plant is now rare in Egypt, and is not cultivated as in former times, when it constituted a source of riches to the inhabitants of the borders of the ancient lakes of Meuzaleh and Bourlos. It is still found growing in marshy places in some of the countries bordering on the Mediterranean. The papyrus or paper of the ancients was made from the cellular substance or inner rind of the stem, thin slices of which were laid over each other transversely, moistened and subjected to considerable pressure. They were afterwards exposed to the rays of the sun, so as to acquire a sufficient degree of dryness, and were ultimately sized. The slices cohered together by means of the mucilaginous matter which enters into their composition. This paper was formerly made on a large scale at Alexan- dria and other Egyptian cities, and yielded a con- siderable revenue both to the manufacturers and the government. The mode in which it was prepared was for a long time lost, and has been only recently discovered by some Egyptian travellers. This plant was used by the Egyptians as medicine, food, and fuel. Sugar was procured from it, and its fibres were manufactured into canvas and ropes. The top of the stalk, with th« umbel of flowers, CYPHONID^E— CYPRINOID^E. 233 adorned the temples and crowned the statues of the gods. Boats were made from the plant, and its root was frequently chewed. Scir})iia is another genus of the order, some of the species of which are applied to economical uses. Scirpus laciwtris, lake club-rush or bull-rush, is frequent on the margins of lakes and ponds in Britain. Its stems constitute a considerable article of trade in consequence of being used for mats, chair-bottoms, &c. They are employed by coopers to fill up the spaces between the seams of casks. Scirpus mantimus, another British species, is eaten by cattle. Its roots have been ground and used instead of flour in times of scarcity. Scirpus tuberosus, the water-chestnut of the Chinese, yields tubers which are eaten either boiled or raw. Many other species of the genus are used for domestic purposes, such as stuffing cushions, and forming the wicks of candles. Eleocharis ccespitosus, scaly-stalked spike-rush, is abundant in moist heaths in this country. It is called Dfert.-hair in the Highlands, and in spring yields an abundant food to sheep on the mountains. The genus Carex furnishes numerous species which grow in swamps, bogs, fens, and marshes, and which are often with great difficulty distinguished by bota- nists. The known British species amount to sixty- three. With the exception of a few species, they are of little use or beauty. In Kent the larger species are used for tying hops to the poles. In Italy they are put between the staves of wine casks, and are used for the purpose of covering Florence flasks. The roots of Carex arenaria, disticha, hirta, are slightly aromatic, and possess diaphoretic and demulcent properties. They are used as a substitute for sar- saparilla, and are commonly known by the name of German sarsaparilla. The first of these species is common on the shores of Britain, and is useful in binding together the loose sand. Carex sylvatica, when carded and dressed, is used by the Laplanders to protect their feet from cold. Carex Fraseri is the handsomest species of the genus, resembling at a short distance, when in flower, some of the lily tribe. The various species of Eriophrium receive the name of cotton grass, on account of the silky tufts of a wool-like substance which cover their seeds, and which render some of them peculiarly conspicuous in almost all marshy grounds in this country. CYPHONID^E. A sub-family of coleopterous insects. See CABRIONID^:. CYPRESS. See CUPRESSUS. CYPRICARDIA (Lamarck), CHAMA (Gmelin). This genus of shells has been separated from the CharruE, by Lamarck ; it nearly approximates to the genus Cardita in form, but may be easily distinguished from it by having three teeth beneath the apices, like those of the C. Venus, in addition to the callous lengthened tooth or ridge ; the ligament is very long, but slightly or not at all projecting, the abdominal impression sometimes placed anteriorly. The animal, according to Poli, is nearly similar to that of the Car- dita, in consequence of which modern authors have made this genus a sub-division of the genus Carditn. The species appear to inhabit rocks, only occasionally covered by the influx of the tides, in the warm lati- tudes. The genus is placed in the third class, Ace- phalophora, second order Rudista, sixth family Sub- mytilacea. CYPRINA (Lamarck), VENUS (Linnaeus). This f$enus of molluscs appears intermediate with the genera Cyclas and Venus. The Cyprince are, in gene- ral, of a large size, much resembling the Vcneres. but are distinguished from them by having one impressed lateral tooth on the front side, sometimes obsolete, the callosities of the hinge are large, arched, terminated near the apices by a cavity, sometimes very deep ; the ligament is external, partly fixed beneath the apices. From the molluscs of this genus possessing a lateral tooth, though it is sometimes obsolete, and their being covered with an epidermis, they may be conjectured to inhabit rivers at their junction with the sea. The form of the shell is regular, longi- tudinally substriated, equivalve, inequilateral, the summits very much recurved forward and often con- tiguous ; the muscular impressions sub-circular, very distant, united by a straight ligula, marginal, and a little sinuous towards the anterior ; the impression of the retractor muscle, anterior to the foot, very large and united to that of the adductor muscle ; the shell possesses an epidermis, and in substance it is thick and heavy. The animal has been described by Fa- bricius, but it requires a further knowledge of its organisation to enable us to adopt his definition, which is very obscure ; it is, however, by analogous reasoning placed in the third class Acephalop/iora, second order Rudista, eighth family Conchacea, Not more than two or three recent species are known, and about seven fossil. It inhabits northern climates, and one species is a native of Iceland. CYPRINOID^E— The Carp family. The first of the five families into which Cuvier divides his first order of soft-finned fishes, or those which have abdominal fins, that is, which have the ventral fins attached to the abdomen behind the pectorals, and unconnected with the bone of the shoulder. This family have the mouth small, the jaws feeble, with little opening, and very often without teeth, but with teeth on the pharynx, which compensate a little for their absence from the jaws. Their bodies are scaly, and they have not the soft dorsal fin which is found in the salmon family. They are the least carnivorous of all the finny tribes. They are all inhabitants of the fresh water, and there is such resemblance among them, that it is often difficult to distinguish the one from the other. Most of them are esculent, but their flesh is not of the first quality. Cuvier divides them into eight genera : Ciprinus, the carp; Cobitis, loche ; Anableps ; Pacilia; Labias ; Fundulus ; Molinesia; and Cyprinodon ; some short account of each of which will be given in its place in the alphabetical order of this work. The genus Cyprinus is farther divided into eleven sub-genera: Carp, properly so called, which is the typical sub-genus ; Barbus, the barbel, of which an account will be found in the article BARBEL ; Gobio, the gudgeon : Tinea, the tench ; Cirrhinus ; Abrama, the bream ; Lubes ; Catastomus ; Leuciscus • and Gonorhynchus. Some account of such of these as have any interest for the general reader, will also be found, either under their generic names, or their English ones, where they have any ; and, therefore, the remainder of this short notice may be restricted to a very brief mention of carp, properly so called. CARP (Cyprinus). These have the dorsal fin longer than the other, with a toothed spine for the second ray of the dorsal and caudal fin. Some have fleshy beards, or filaments at the angles of the upper jaw, and others are without. COMMON CAHP (Cyjmnm carjrid). This species 1234 C Y P R I P E D I U M - C Y R T A N D R A C E X.. has four beards to the mouth, the lateral line a little bent, and the tail forked. It is not understood to be a native of England, but to have been introduced as a pond-fish about the latter part of the fifteenth century. It is found native in the lakes and ponds of the south of Europe, and it is much more common in France and in Germany than in this country. Its flesh is tolerably good, and it is serviceable as a pond-fish, because it is remarkably tenacious of life, and therefore can be carried over land from one place to another. Instances are mentioned of its having been carried alive from Straslmrg to Paris, by keeping a little humid moss in contact with the gill-lids ; and, indeed, it will live a long time without even that simple operation. Carp is not a fish of the troubled waters, and its motions are as restrained as those of the element in which it lives. Placid streams, which creep along without anv perceptible current, the moats and trenches of* ruined castles, shaded and mantling ponds, which are left to the operations of nature, and in which aquatic plants accumulate, are the favourite localities of carp. It feeds quietly upon those sub- merged vegetables ; and from the quietness of its Jiabits, and the little fatigue which it undergoes, it lives to a great age, not less, it is said, than a hundred years, by which time its back is understood to get entirely white. It is not timid, but rather fond of society, and capable of being so far educated, as to come and be fed at stated hours, on being whistled to by its master. The stilly part of the Rhine, near Strasburg, contains immense numbers of carp, in which a considerable trade is carried on with Paris ; and it is found as far to the eastward as Persia ; but it is understood to prefer more temperate climate?, and does not grow to so large a size in very warm countries. Specimens have been mentioned of nearly four feet in length, but it is rare to meet with one more than two. Though the carp feeds a good deal upon vegetable matter, it also eats worms and aquatic insects, and, as is sometimes said, it swallows the mud at the bottom of .its haunts for the sake of the larvae, and seeds which are contained in that. Hence the flavour of its flesh varies, much depending on the nature of its food. Carps spawn in June, and are very prolific. Besides the common carp, there are mentioned, the King of the Carps (Rex cyprinorum], but it is doubtful whether this is a species ; yet its scales are remarkably large, often an inch in length, and it appears to be more northerly than the other ; also, the Ann-Carolina Carp, of Lacepede, a Chinese spe- cies, very handsome and beautifully coloured ; and the Green-violet, of the same author ; but little is known respecting them. Of those which are without beards to the jaw, the most celebrated is — The GOLDEN CARP (Cyprinus auratus'). This is the well-known gold fish from China, and needs no description. A silver fish from Asia is also men- tioned, but it is possible that this may be nothing more than the former discoloured by age. CYPRIPEDIUM (Linnaeus), is one of the most interesting of the Orchidetz. The C. calceolus is a native of Britain, and one of the most curious of her productions. Generic character : sepals patulate and distinct, the upper ones often united like a helmet, the two lateral ones divaricating ; labellum inflated ; upper part of the column trifid, lateral lobes bearing anthers, middle one sterile and glandular ; pollen granular. This, as well as the American species, should be planted in moor earth, in a frame or shady border, and defended from severe frost and heavy rain. They sometimes ripen seeds, by which they may be increased. CYPRIS (Muller). A genus of minute crusta- ceous animals belonging to the sub-class Enlonuistracn and order Branchiupoda (which see). These little creatures swim about with great velocity in standing and fresh waters, their bodies being inclosed in a kind of bivalve case united by a hinge, which enables them to close their shells on the approach of danger. They have only six legs, and the antennae are terminated by a whorl of hairs like a pencil ; the body is with- out distinct articulation, terminated posteriorly by a soft tail. According to Jurine, who has observed these insects with much attention, the antennas are employed in swimming, and the two fore legs are used when the animal creeps upon the surface of aquatic plants. He says that the second pair of legs are employed in establishing a motion in the fluid, whereby small particles of food are directed to the mouth ; the tail is divided by two fillets, which are folded together when coming out of the shell ; the eggs are enclosed in two large bags at the sides of the body beneath the shell : the female is occupied for about twelve hours in depositing them upou aquatic plants. As in the Cyclops, J urine observed that several generations are capable of being pro- duced without more than a single coupling having previously taken place. There are numerous species, inhabitants of our standing waters. The allied genus, Cythera of Muller, has eight legs, and the antenna.' are not terminated by a brush ; the species of this genus are confined to the salt water of tho ocean. CY11ENA, (Lamarck). A genus of shells, united to the genus Cyclas by de Bluinville, of which he makes it a subdivision with considerable propriety. These shells are iound in rapid rivers and streams ; they are thick and .solid, shells, sometimes of great size ; the apices eroded or carious, covered with a green or brownish epidermis, and admirably constructed to endure the rough treatment they experience from their peculiar habitations ; their classification will be seen under the article Cyclas. CYRTAN BRACED, a natural order of dicoty- ledonous plants, containing only a few genera and species. By Don and some other botanists it is denominated Didy»wcarpe vcllow hue. '286 DAHLIA-DAPHNE. DAHLIA (Cavanilles). A large south American tuberous-rooted herbaceous plant, introduced via Spain in 1789. It belongs to the class and order Syngencsia superflua of the sexual system, and to the natural order Composite. This plant is now so com- mon as to need no specific description. It is met with everywhere, in the garden of every cottage as well as of every palace, and among cultivators, in sach quantities that it is truly astonishing to conceive where a vent can be had for them. No plant has been more extensively cultivated than the dahlia, and no plant has repaid the labour and care bestowed on it with more varied forms and colours than this. In form and stature it is a Proteus ; in tints it is a vegetable prism. Neither is the form nor colours constant in the same individual. The first flowers will be single, and of one colour, and the last double, and of another hue ; and such is the versatility of the self-colour of a parent, that its seedlings will be edged, or striped, or blotched, and altogether as unlike the mother as change of colour can make them. The dahlia partakes very much of the nature of the potato ; they are natives of the same quarter of the world, flourish with us during our summer, and, being both tuberous-rooted plants, liable to suffer from frost, require to be taken from the ground and winter-stored in the same secure manner. There are many different plans resorted to in grow- ing the dahlia. Every cultivator aims at having plants of diminutive tature, bearing numerous, large, and richly-coloured flowers. For this purpose, the follow- ing rules are laid down by the most successful growers : About the 20th of February, the tubers ate taken out of the dry sand, or from off the shelves in and on which they have been stored for the winter, and partly buried in the bark-bed of a hothouse, or the dry soil of a mild hotbed made up for the purpose. Here they very quickly produce shoots. When these are about four inches long, slip them off, and pot them singly in proper compost, replunge them in the bed, where they may remain till the season allows of them being turned out into the borders. The young plants can seldom be placed out of doors with safety till after the middle of May ; and if, at planting time, they be tall or slender, they should be staked, to prevent injury from wind ; and as they gain height and volume in the course of the summer very strong staking will be necessary. They should not have too rich soil to grow in ; dung should never be used, because this only en- courages luxuriance of stems and foliage, without either expediting flowering, or causing an increase of size or beauty of the blossoms. The following com- post is much used and approved of: — One-fourth mellow loam, one-fourth leaf mould, one-fourth fresh turf soil, and a like quantity of pit or river sand of pure quality and white colour. A very extensive and successful cultivator was asked the other day whether or not the dahlia-fancy was nearly over ? He replied, it was only beginning ! for, notwithstanding the vast number of magnificent varieties now in cultivation, they would soon give way to other various tinted kinds which are every year raised from seeds. All are endeavouring to raise a blue variety — an object, according to Professor Decandolle, which is never likely to be seen. DAHOON, is the specific name of a species of holly found in Carolina, and introduced into our gardens a? far back as 1726. DAISY, is the IBellis pere nnis of Linnaeus, and one of our most common British pasture plants. Its humble growth, and pretty little composite flowers, are one of the principal spring ornaments of every piece of turf. There are three garden varieties of it, viz. the large double, the double quilled, and the proli- ferous, or hen-and-chicken daisy, all common in (lower borders, and sometimes planted as edgings to them. DALBERGIA (Roxburgh> A genus of stately trees and twining shrubs, natives of the East Indies. Linnsean class and order, Diadelphia Decandria, and natural order Leguminosce. Generic character : calyx bell-shaped, five-toothed ; keel split at the base ; pod on a membraneous footstalk, not opening, and con- taining from one to three seeds. These plants grow well in sandy loam, and are propagated by cuttings struck in sand. DALE A (Linnaeus). A geniis of annual and perennial herbs, natives of central America. They belong to Monadelphia Decandria, and to the natural order Leguminosce. This genus is allied to Psoralia and Galega. Several species of it are kept in our greenhouses, and propagated by cuttings, but which, if exposed to much humidity, are liable to drop off. DALECHAMPIA (Linnaeus). A climbing tropi- cal genus of plants, natives of Brazil, belonging toJDoj?- cia Diandria, and natural order EiiphorbiacccE. These are seen in stove collections, and are grown in loam and moor-earth, and are easily propagated by cuttings. DAMMARA (Rumphius). A genus of lofty- growing forest trees, of the Pinus family, found at Amboyna and in New Zealand. This was called Pinus dammara by Lambert, Agathis loranthifolia by Salisbury, but now a separate genus as above. Rooted plants grow freely in sandy loam and moor- earth, but are very difficult to strike from cuttings. DAMPIERA'(Robert Brown). A New Holland genus named in honour of Captain W. Dampier, a celebrated navigator and botanist. It belongs to Pentandria Monogynia, and to the natural order Goodenoviae. It is easily propagated by cuttings. DANDELION, is the Leontodon taraxacum of botanists, and one of our most common and conspi- cuous British weeds. It annoys both the farmer on his arable land, and the gardener among his crops ; to the latter it is a disgrace, if suffered to flower. Nature has done much for this plant, even the smallest portion of its root, forms a new plant, and its seeds, being furnished with a most elegant flying appendage, are transported far and wide by the wind. On the continent, the leaves, when blanched, are preferred to endive ; and it is said that, when the roots are oven-dried and ground to powder, they are no bad substitute for coffee. Goats, sheep, hares, and rabbits, are fond of the leaves ; but it is by no means a desirable plant either in meadows or pastures. DAPHNE (Linnaeus). A rather extensive genus of highly ornamental shrubs, natives of many different countries, though chiefly European. Linnajan class and order Octandria Monogyiiia, and natural order Thymelete. Generic character : calyx corolla-like, funnel-shaped, withering without dropping off, four- cleft ; stamens inserted in a double series on the tube ; anthers roundish ; style very short ; stigma headed : drupe many-seeded. There are above twenty species of the genus, and many varieties, some of them exceedingly ornamental. Some are stove, others reenhouse, and the greater number hardy. A few D A P H N I A. 237 are propagated by layers and cuttings, but most are increased by grafting' on the common wood-laurel (D. laureola], or on the mezereum. Some of the smaller sorts grow well in moor-earthy soil, prepared for American plants, but most of them thrive in any light soil. DAPHNIA (Miiller ; MONOCULUS, Linnaeus). A genus of small crustaceous animals belonging to the sub-class Entomottraca, order Branchiopoda, and sec- tion Lophyropoda. The body is of an oblong oval, and compressed form, evidently enclosed in a bivalve shell, attached to the skin, having its aperture beneath the body, and its hinge above the back. The head is distinct, and produced beneath into a kind of snout, furnished with a single central small eye. From each side of the head arises a large antenna-like organ, having a long basal joint, at the extremity of which each antenna is divided into two long articulated branches, each of which supports a number of long bristles. The functions of these organs in swimming, being, in fact, the only external apparatus employed in this motion, has induced M. Straus to regard them as forelegs, although it is evident, as Midler and Jurine observed, that they represent the upper antenna; of the typical crabs. And here we may take occasion to notice the great difficulty existing in the determina- tion of the nomenclature of these and other organs, in groups of animals which recede so entirely from those which, by common consent, are considered as the types or normal divisions of the class — and, indeed, the remark is applicable in every other branch of the creation. We mention this subject because Dr. Johnston, the celebrated naturalist of Berwick-upon- ,Tweed, has recently published some observations bearing upon this view of the question in the Maga- zine of Natural History, which deserve attention. — Speaking of one of the species of the shark parasite, Pandarus alntus, he says : " The student who is anxious to see how ingeniously the few and simple organs of this creature can be analysed and resolved into parts corresponding with the complex organs of the crab \ ami lobster, must consult the interesting memoir of j Milne Edwards (in the Dictionnaire des Sciences j Naturelles, vol. 28). I must acknowledge that the analogies seem not a little imaginary, and the nomen- clature derived from them is at least faulty, in so far that it gives, or is apt to give erroneous ideas relative to function ; the feet-jaws are not subservient to man- ducation in any way ; the animal is suctorial, and requires no jaws, and these organs are used solely to obtain fixedness of place, while the thoracic feet again are not organs to walk or creep on, but are only cal- culated for swimming, which, we can conceive, it may often have occasion to do." Although we admit to its full extent the soundness of Dr. Johnston's remarks, in examining an animal per se ; we certainly do feel, when investigating the same animal with reference to the structure of the remainder of its class, that the great difficulty with which the subject is surrounded ought to make us hesitate before we condemn a series of names which the strictest analogy has proved to be correct. Let us, however, look at the matter with reference to some of the better known examples of the class. Examine a lobster and a crab, and the mouth is found to be externally composed of several pairs of flattened organs, having a transverse motion, and evidently acting as jaws, whilst the large pair of fore legs is terminated by great and powerful claws. Now, examine a spiny lobster (which is not uncom- monly to be met with in the fishmonger's shop, belong- ing to the genus Palm urns], and the claws are no longer to be seen ; in their stead a pair of limbs are found, having indeed the same number of joints as claw-legs, but formed like the following legs, and evidently being employed in locomotion. But will it be said that the least stretch is, given to our fancy when we assert that the leg of the Palinurus is the claw of the lobster in a modified state of development, or that the former analogically represents the latter ? Should we incur the chance of ridicule if we describe the claw of the lobster as a leg, although it be em- ployed only in prehension, and not in locomotion ? — Let us, however, now examine one of the little leap- ing shrimps, so common on the sea coast, and of which one species abounds in fresh water (Gannnarvs pulex\ and we find the mouth deficient in a certain number of pairs of organs, but that the legs have obtained an increase of the same number of pairs ; whilst the examination of such genera as Sergcstes, Sicyonia, &c., clearly demonstrate the transition of structure and function from mouth organs to legs. Will it be said that we are adopting a faulty nomenclature, because we employ a term for these thus transitory organs, which indicates that they are liable to this singular kind of transition ? We are aware that, by the un- thinking, and by those who would lead the unthinking by the employment of arguments resting upon general and, as we may say, vulgar observation, rather than upon accurate but difficult analysis, we should be ridiculed in asserting that the sucker of the butterfly, and the under-jaws of a beetle, are the same organs in a different state of development, and in applying to both the same term ; but we contend that the argu- ments which we have above brought forward are applicable to one case as well as the other; that there is no fanciful theory to be built upon this strict appli- cation of the rules of analysis and its consequent an- alogy, and that when, by the application of the former, and the adoption of the latter, we arrive with certainty (and here, as we said in the outset, lies the great diffi- culty) at the conclusion that a certain organ in one animal is the representative of an organ in another ani- mal, we are at liberty in a strictly philosophic view of the subject to apply to both the same name, although in common parlance it is necessary, perhaps, to use different terms indicating the precise functions of each organ. Within the shell of the Dnphnia are to be observed ten small leg-like organs, having the second joint vesicular, the eight anterior ones being terminated by a dilated joint, margined with hairs, and serving as oars, the anterior pair appears, however, to be em- ployed more especially in prehension ; the posterior pair of legs is differently constructed. By a curious provision the eggs are deposited in a dorsal kind of pouch beneath the shell within which they are hatched ; at the end of the fifth day the young have acquired sufficient power to take care of themselves, and are expelled by the female. These animals, of which there are numerous species, are found in fresh and standing water, where they swim about with very great agility, their large branch- ing antennae giving them a curious appearance, hence they form interesting objects for the microscope. — Their history has been traced, notwithstanding their minute size, by several eminent observers, the works of Messrs. Schaeffer, Ramdohr, Straus, and the elder .lurine may be especially mentioned. By Swammer- 238 dam, also, they were noticed under the name of Putex aquations nrborescens, the latter name being given to them in allusion to their branching antennae. It has been observed as a remarkable circumstance, of which but few instances occur in nature, that a single impreg- nation is sufficient for several (six or more) genera- tions. An analogous law occurs amongst the plant lice (APHIDES, which see). Occasionally these insects abound in stagnant water to such a degree as to im- part to it their own tint ; and as one of the species is of a red colour, the colour thus imparted to the water has been supposed to have been caused by blood. The type of the genus is the species above men- tioned, or the Monoculus pulcx (Linnseus). It is about one-twelfth of an inch long, and in spring is of a red colour, which towards the summer becomes rosy; but at other seasons it becomes of a greenish white colour. It is very abundant. DARNEL, is the Lolium temulentum of Linnaeus, a species of grass too often found in autumn-sowed crops of corn. If its seeds, which are nearly as large as those of rye, are mixed with wheat, and made into Hour therewith, it renders the bread bitter and un- wholesome. Indeed, the plant is the dread of farmers, and the seeds are detested by the miller ; nor is there any easy way of ridding the wheat of it, if thrashed together. Hand-picking the sheaves, as they pass through the hands of the binder and thrasher, is most effectual, because neither sieve, nor skreen nor fanners, can separate the darnel from the wheat ; and if a single grain of the former be seen in the sack at market, the value of the latter is very much reduced. There are two old popular errors relative to this plant which are not entirely discredited at this day. The first is, that it is the plant whence the cultivated wheat was originally obtained, and that wheat may be grown till it all turns again to darnel ! This is truly ridiculous ; for, except being in the same natural order, no two plants can be more unlike in quality than the Lolium temulentum and the Triticum hyber- nmn, or common wheat. It is said to be sometimes used in the manufacture of low wines, for the purposes of the compounder of strong liquors ; but this requires confirmation, as it is «o strongly poisonous. There is another grass which is sometimes con- founded with darnel, because it is sown and reaped, and appears in the sample along with true darnel. This is the Bromus secalinum, a plant yielding seeds little inferior to small oats, and of fully as good quality. This last is called ray, and the other is called by its right name, darnel, though they are often mistaken for each other. The one is sweet and wholesome, the other bitter and stupifying. DARTER — Anhinga. — A genus of web-footed birds belonging to the pelican family, and in many of their appearances and habits nearly allied to the cormorants. The species are not very well made out ; but as the nearly allied genus of the cormorants is subject to considerable varieties of colour, both with age and with season, it is probable that the birds which have been noticed as differing a little from each other are all of (he same species. The species which is best known, if not the only species, is the white billed anhinga (Plotus melano- gaster), which is found in the humid parts by the rivers, pools, and lagunes near the snores in the southern part of the United States, in Brazil, and DARNEL— DARTER. other parts of South America ; and also on the humid parts of the west coast of Africa to the south of the desert. Darter. The length is about two feet ten inches ; the wings long ; the tail very long, the head and neck slender ; the bill long and perfectly straight ; the mandibles enlarged at the base, tapering to points at the tip, and finely serrated in the tomia ; the upper mandible slightly channelled on each side ; the nostrils linear in the channels, and concealed by a membrane ; the tarsi short, but very thick and strong ; all the toes webbed, the web of the hind toe joining the inner one as in the cormorant and all the birds which dash into the water for fish ; the toes armed with crooked claws. The head is smooth, the colour of the belly white, all the other parts raven black, except a few mantlings of white on the tail. It reposes on trees, where it also nestles, finds its food in the waters, and is rarely seen on the ground. When in a state of repose, the long neck is folded back upon the shoulders, and the bird stands upon the top of the tree rather than perches. Its perch or nest is seldom far from the water ; and when the weather is very sultry, it may be often seen standing on a branch which projects over the water, and ex- panding and moving its wings and tail, as if producing a current of air to cool it. On these occasions it is said to contemplate its own image in the stream, but that wants confirmation, though many birds are known to be much interested with looking-glasses. If disturbed while thus fanning itself, it drops head foremost into the water as if shot, or rather struck by lightning, and instantly disappears, producing very little rippling, as its pointed bill, slender head and neck, and finely tapered shoulders, divide the water with the greatest ease. After a little time it ascends and shoots out of the water like an arrow at a con- siderable distance from the place at which it dived. At other times they fly high over the waters, and with powerful wing, darting down occasionally and capturing fish, which they do with great rapidity and certainty. They are social birds, always found in packs, and sometimes in pretty numerous flocks ; and though they are thus numerous in the same locality, they are generally fat, as they resort only to those places where they find plenty of food. They frequent only the perennial waters ; they do not need to fatigue themselves by migrating from place to place. Their nests are rudely formed of sticks in the tops of the DARWINIA—DASYURUS. trees, in a manner resembling those of the cormorants but as the places in which they build (often in the mangroves) are not very accessible on account of their swampiness, and as they are besides not a little pestilent, the family habits of the birds are not very well known. They are birds, however, which form a feature of the peculiar localities which they inhabit. They are not much disturbed, as their flesh is rank and bad. DARWINIA (Rudge). A genus of two orna- mental shrubs from New Holland. Linnae;m class and order Decandria Monogynia, and natural order Rhamnece. Generic character : — calyx like a tubular coralla, limb five cleft ; corolla none ; stamens very short, in a double series on the throat of the calyx ; anthers oblong ; style long and protruding. Easily propagated by cuttings. DASYCHIRA (Hiibner). A genus of lepidopter- ous insects, belonging to the family of Moths, Arctiidce, having the wings rather long, and the palpi very short and hairy. The spiral tongue is obliterated, and the fore legs very hairy ; the caterpillars are very hairy, being furnished with pale tufts of hairs, which render them very conspicuous, and from which they have obtained the name of tussocks ; the cocoon is of a close texture, having the hairs of which these tufts are composed worked into its meshes. There are two British species, the dark tussock (Borqbyx fascelina, Linngeus), about two inches in expanse ; and the pale tussock (B. pudibundn, Linnceus), a common species in the neighbourhood of London, rather larger than the preceding, having the wings of a •whitish ash colour, the anterior pair having a central lunate spot, and three waved streaks of a brown colour. In Kent, the caterpillars are found in the hop gardens, and are called hop dogs. DASYPODA (Latreille). A genus of hymen- opterous insects, belonging to the section Mettifera, and family Andrenida;, or short -tongued bees. The species are of moderate size ; the hind legs, especially in the females, are, as the generic name implies, very hairy, the basal joint of the tarsi being very long, and furnished with a complete brush of hairs ; the wings have two complete sub-marginal cells ; and the tongue is lance-shaped, and folded back upon the upper surface of the horny mentum. There is only one British species of this genus, and which was dedicated to Swammerdam by Mr. Kirby, in his History of the English Bees, in which work we find the following account of the habits of this pretty and interesting species : — " No person, at first sight, would take the male and the female of M. Swammer- dnmdla for the same species, so widely do they differ in most particulars ; nor should I have suspected that there was any connection between them, had I not discovered their retreat. In the month of August, 1797, I saw a female take her flight from a grassy declivity of a southern aspect, which was much entangled with roots and shrubs. Upon ex- amining this spot more narrowly, I discovered a number of small burrows, each of which had a little heap of sand, which had been excavated from it, lying before it. In some of these burrows I saw our melitta (Swammcrdamellci) sitting, with her head at the mouth, enjoying the sunshine. At the same time I observed many other insects flying about the spot. Upon my attempting to take them, they disappeared, but they soon returned to their amusement. With some difficulty I at length succeeded in taking one, and it proved to be the male." — Vol. i. p. 176. The body is of a black colour, clothed with pale fulvous or ochreous hairs, the abdomen of the female with three whitish belts, and the hind legs with orange hairs. It is rather a rare species, although occasionally met with in certain localities in some quantities. The food of the larvae consists of pollen paste, stored up in cells by the female, which prefers the pollen ot such flowers, as Crepu, Hceracium and Leontodon. DASYPOGON (Meigen). A genus of dipterous insects, belonging to the section Tanystoma and family AsilidcE. The body is long and thickened, often woolly ; the antennae are shorter than the head, with the terminal style distinct and conical, not terminated by a bristle, and the proboscis is straight. This is an extensive exotic and European genus, forty-four European species having been described by Meigen ; two only have, however, been found in this country'; namely, D. punctatm (Fabricius), which is exceedingly rare ; and D. brcvirostris, forming the type of Mr. Stephens' genus Lcptarthrus, established upon the very slender form of the posterior tarsi in the males. This species is of a black colour, with the four posterior tibiae red at the base. We have met with it in the beginning of July, in some abun- dance, amongst grass, in the Devil's Ditch, on New- market Heath. DASYTES (Paykull). A genus of coleopterous insects belonging to the section Pcntamera, subsection Seiricornes, and family Mdyridce, having the antennae' as long as the head and thorax, the body narrow and sometimes linear, the claws of the tarsi generally fur- nished with a membranous appendage, palpi filiform, and body destitute of the vesicular lobes visible in the Malachii. The name of the genus is of Greek extrac- tion, and is given to these insects in consequence of the numerous hairs with which they are clothed. But little is known of the early history of these insects, which, in the perfect state, are generally found upon grass and umbelliferous flowers, in hedges, trees, &c; The species are numerous, and often prettily varie- gated in their colours ; the indigenous species are of small size. Dejean, in his new Catalogue, gives seventy-four species, the majority of which are Euro- pean and Brazilian. Stephens gives eight British species, of which the D. cceruJeus of Fabricius is one of the prettiest, being of a bright blue colour. It is about a quarter of an inch long, and is found on the southern coast. Some of the other species present various curious peculiarities of structure, such as the legs spined and twisted, the body quite linear, &c. DASYURUS (rough and hairy tail) a genus of marsupial mammalia, peculiar to Australia, and in some of the species peculiar to the larger island, New Holland, and in others to Van Diemen's Land. It is worthy of inquiry what geological epoch of a country requires the presence of the marsupial or pouched mammalia in it ; but the reasonable conjec- ture, from the fact of at least one marsupial animal being found in a fossil state in Europe, while within the period of history there has not been a living one found native nearer than America, would lead to the supposition that they are adapted for rather an early, age, as respects the formation of the peculiar locality, if, according to what appears to be the most rational theory on the subject, we are to suppose that coun- tries like their productions have a beginning, a dura- tion, and an end ; and that as they in all probability outlive races of animals, just as races outlive genera- 240 D AS Y U RUS. tions, the earth will be able to produce country after country, for a succession of changes, of the term of whose performance we can frame no conjecture, before the powers of the globe become unfit for the produc- tion of another new land ; and so the ages of its duration are at last numbered, and it is by some great power, which is still an instrument in the hands of its maker, scattered in viewless atoms through the regions of space. This is a subject of great interest as well as curiosity, to which we shall briefly revert in the article Marsupiata, and more at large in the general article Mammalia, so that we must in the mean time confine ourselves to a very short notice of the genus, of which the systematic name stands at the head of this article. The animals of this genus, some of which are how- ever but imperfectly known, are almost, if not alto- gether, the only carnivorous mammalia of the exten- sive countries in which alone they are found ; for there is little doubt that the dingo, or wild dog, (which, however, may be said to be in a state of domestica- tion, bearing the same relation to the domestication of the dog in Europe, as the state of the native of Australia bears to European civilisation), the dingo is, probably, nay certainly, an importation by the Malays, •which have long resorted to the north-eastern parts of New Holland to fish for trepang (Holothuria), for the supply of the Chinese market, It is a remarkable fact that the carnivorous animals of Australia should be more so than the marsupial animals of other countries, while animals that are wholly herbivorous are also in the same country furnished with similar appendages. But though the fact is striking, we are not in the present state of our knowledge able to deduce from it any conclusion which enables us to connect any thing in the physical geography of Australia, which peculiarly adapts it to the habits of those pouched animals. We cannot let slip this first opportunity which has occurred in the order of alphabetical arrangement of noticing these singular animals, which unite indications of a physio- logical nature more than any other class of animals, without mentioning how desirable it would be to pay somewhat more attention than is usually paid to those circumstances, of a nature bearing upon both (of course) which link peculiar animals to their peculiar localities. In many instances, there is no doubt that the abundance of its most favourite food which the locality affords, has a very considerable influence in determining the animal towards that locality ; but this can hold true only in the case of migrant animals, and will not apply to such genera as that under conside- ration, which have uo means of crossing the sea by which their country is surrounded. The genus Dasy- urus must be a native of Australia ; and what is more, as there are some which are met with in the smaller island only, and some only in the greater, and as the differences between these are of too decided a character for our admitting the possibility of the one being a climatal variety of the other ; and, further, as there has been no artificial training calculated in the least to change either one or other of them, the question becomes one of still greater interest to every one who would wish to obtain a solution of the most interesting problem in the whole range of national history — why animals should, in their physiological structure, differ from each other ? — why should almost the whole of the native mammalia of Australia bring forward their young by a double gestation, the one in an internal uterus, and the other in an abdominal pouch, while in Southern Africa, the latitude of which is the same and the climate not very dissimilar, there is not a single animal having even a fundamental ves- tige of this double gestation. The genus Dasyurus has been, by various natural- ist.*, divided into several genera; but as there are very strong resemblances between them all, we shall in- clude our brief notices of them all in one article. In- deed, there is a characteristic physiognomy which runs through the whole of the marsupial animals, what- ever may be the character of their food, their habits, their size, and even the forms of their bodies, which shows them to be a race actually belonging to a dif- ferent system, and apparently a different epoch, from the common placental mammalia, of one internal gestation. "Whether their fur be rough or smooth, it does not appear of the same texture as that of our mammalia ; and there is, generally speaking, a rug- gedness in their appearance, and a want of specula- tion in their expression, which makes them look as if they were not at home in the present period of the world's history, and did not form an appropriate part of its economy. Their generic characters are : six grinders or cheek teeth in each jaw, of which the two anterior ones are compressed and trenchant, and the remaining four tuberculous, resembling those of insectivorous mam- malia ; their incisive teeth are small in size, eight in the upper jaw, and six in the under ; and they are furnished with four canines ; but the teeth altogether have a ragged appearance compared with those of the placental carnivora, and at the same time there is an apparent want of vigour in the jaws. They have on all the feet five toes, which are long, and very dis- tinct in their phalanges, and armed with crooked claws, with the exception of the thumbs on the hind feet, which are little else than rudimental, and without any claws. The last phalange of the hind toes is furnished with a tuft of long hair, which extends for- wards, and covers the claws. Sexually, the male agree with the opossums in the bifurcation of the organ, and in some other particulars, and there is that air of correspondence which we have remarked, as being characteristic of all the marsupiata ; but they are without the climbing feet of the opossums, which, from the reversed thumb, are enabled to take hold of branches much in the same manner as the ai-ai. The ears are rather short and covered with hair ; the tail is long and hairy, generally thick at its insertion, and in some of the species it is compressed laterally ; but it is not prehensile in any of the species, neither areany of themcapableof climbing for their food. They live much in concealment, and resemble in their habits the fox and the polecat, more than they do any other of the mammalia of Europe. They are all ravenous in proportion to their size ; but their food vaiies consi- derably. The structure of their cheek teeth shows that they all can subsist upon insects ; and it is probable that these constitute the principal food of the smaller ones. But those which are ot more formidable size prey upon the smaller kangaroos, the ornithorhynchus, and bats, which are very numerous in some parts of the country. They also prey along the shores, eat- ing indiscriminately mollusca, fish, and any carrion or garbage however putrid. They are also said to plun- der the poultry yards of the colonists in waste places, and also to destroy lambs. Their dispositions are bad, but even the largest of them have not courage in pro- D A S Y U R U S. 241 portion to their strength, and it is doubtful it' they ever incline to attack the large kangaroo, or even the emu, unless they can ccuno upon it by stealth ; the colonists have given them the names of those Euro- pean and other animals to which they fancied they had the greatest resemblance, such as cats, wolves, hyaenas, leopards, and other names ; but there does not appear to be a single native animal, or any one of those genera, in the whole of Australia. There are at least eight species of the genus, three of which are natives of Van Diemen's Land, and the other h've of New Holland ; but it is probable that as the latter country becomes better known, more species may be discovered. Dasyurus cynocephahts. This species is of Van Diemen's Land, and it differs so much from the others in some of its characters, that it has been made a separate genus under the name ofT/iylncimis. It is an animal of considerable size, being about three feet and a half in length, exclusive of the tail, which measures about two feet. It stands one foot one at the shoul- der, and one foot eleven at the rump, — the marsupial animals being almost, without exception, higher and more stoutly made in their hinder parts than forwards, which forms a very distinguishing character between them and the generality of animals which are not marsupial. The tail of this species is very peculiar, and dif- ferent from that of all the others of the genus, being compressed or flattened sideways. The covering of the animal is smooth and short, of a dull yellowish brown in the ground colour, paler on the under part, and mixed with grey on the back ; and across the loins and rump there are six or seven transverse bands of black, two of which extend down the thighs. This animal squats on its hams in the attitude of a dog, but its expression is dull and stupid, and it has neither the sagacity nor the activity of the predatory animals of Europe. It is generally found near the shores, and lodges in deep caverns and clefts of the rocks, so that it is not often seen in proportion to its numbers. Dasyurus ursinus. This is also a native of Van Diemen's Land, and not found, so far as is known, in the larger island. It is smaller than the former species, and different in all its characters and habits, so that the generic distinctions between them appear to be correct; and it is probable that, when they come to be better understood, it may be necessary to sub- divide them into more than two genera, though they will still require to be kept together as a very natural group. The present species is about two feet and a half long, and the tail about nine inches, and unlike that of the last species, it is naked on the under side, and slightly prehensile. The whole body and upper part of the tail are covered with shaggy black hair, marked on the back with a few obscure white blotches. It is in consequence of this rough covering that it gets the name of the bear ; and its peculiarly repulsive aspect has procured it from the woodsmen of Van Diemen's Land, who are not over chary in their vocabulary, the name of "the Devil." Its manners, like those of most of the genus, are very little known : it lives in obscu- rity, and though, from the character of its teeth, which are the same as those of the former, it in all proba- bility feeds a good deal upon insects, reptiles, and its fellow-lodgers the bats, yet it is said to range more extensively, to be more fierce and daring, and to com- mit greater depredations upon poultry and lambs than NAT. HIST. — VOL. II. the former one ; still, however, when seen, for that is not often, as it is in the depths of caves during the day, it is near the shore, and very generally close by the margin of the waters. It is worthy of a passing remark, as throwing some light upon the natural state of Australia, and this is a subject to which much attention should be paid, be- cause we are in possession of its history, clearly and fully from the very first time that a sod of it was broken by the spade, that both the human inhabitants and the predatory animals of this part of the world were found only on the margin of the waters, chiefly on the sea-shore, but also, at least seasonally, on the banks of the rivers, and that the chief subsistence of both was fish, and at some seasons of the year shelled mollusca. This may, perhaps, account for the very small number of even these species of predatory animals in regions so extensive, and also for the extir- pation of them from the larger island, supposing them once to have been found there, at least it is a remark- able instance of man and the predatory animals being rivals for the very same food in the very same locali- ties ; and we may naturally suppose that rude as were the aborigines of these countries they would exert themselves to extirpate the dasyuri with the same assiduity that the wolf and the fox have been hunted down in Europe, and the former extirpated in many parts of it. The wars of wild men against wild ani- mals, would not only be an exceedingly curious sub- ject in itself, but if it were properly studied it would throw considerable light upon the progressive his- tory, at least, of the predatory part of the animal kingdom. Dasyurus minimus. This is also described as a native of Van Diemen's Land, and has been much more readily met with than either of the other two. It is a very small animal, not above four inches in length, and the tail short, with very short hair, the fur on the body is soft to the touch, and reddish at the points. Its head is conical, and its muzzle very small. Altogether it has fully as much resemblance to the opossum as to the other members of this group. Very little, however, is known of its history. Dasyurus macrourns. This species is found in New Holland, and was for some time described as belong- ing to the weasel family, and named as such by Shaw who was long employed in the naming of beasts, though sometimes not very happily ; but then the fault was not his, as he had only the skin to name them from, and of course had no means of judging of their structure, or assigning them a place in the system, in accordance with their nature. This species is styled the spotted marten, and sometimes the wild cat by the colonists, which has led those who make up works from popular sayings, without having the means of ascertaining their truth, to include the cat among the native animals of Australia, though there is no reason to believe that there is a single individual of the feline group indigenous to the country. This species is about a foot and a half long, with a tail nearly the same length. Its fur is very thick, and soft to the touch, the colour otter brown, relieved with spots of pure white, which are very small on the back, but yet larger on the sides, and the belly is entirely white. The head is maroon red, and the feet yel- lowish. The two incisive teeth in the middle are more produced than the others, which gives the mouth of the animal a ragged appearance. This is a nocturnal animal, Q 242 DATE P A L M — D A U C U S. There is some obscurity about the distinctions of the other species, as it is doubtful whether some of them which have been described from single specimens may not be the young of the one under consideration. The investigation of those disputed points could have little interest for the general reader, and therefore we must refer such as are anxious to be belter acquainted with the carnivorous mammalia of Australia, to the systematic works ; and, from the zeal and ability of many of those who are now investigating the natural history of the colony in all its departments, we have no doubt that information w ill soon be obtained which will be highly satisfactory ; and, therefore, it would be ill-judged on our part to hazard conjecture while in expectation of the truth. DATE PALM is the Phcenlv dactylifera of Linnaeus. This is one of the most useful of the palms, it yielding every year great crops of fine rich fruit, forming not only a valuable part of the food of the lower orders of society, but a vast surplus for exportation to other countries. Persia, Palestine, and the northern states of Africa appear to be the most congenial climates for the successful culture and growth of the date tree. In some of those countries there are extensive groves of them, furnishing employment and wealth to the generally indolent natives. The stem is not so lofty as some of the other palms, but it is comparatively much thicker and very rugged from the persisting bases of the fallen fronds. When the fruit are ripe, they are shaken from the pendent spadix by one man, while others hold a cloth, extended below, to receive the falling fruit. These are afterwards sorted and prepared for packing in jars or boxes for sale. Young date trees may be raised from the stones of the imported fruit ; and as they have much divided and persisting foliage, they add an interesting variety to the stove collection. If planted in a tropical con- servatory, and allowed time and space, there is no doubt but they would flower and fruit in this country, which would, at least, be a great curiosity to British botanists. DATISCE^E. A natural order of dicotyledonous plants containing only a few genera and species. In its habit ami the structure of its fruit, it bears a close resemblance to Acxedaccfe, and seems to be a con- necting link between that order and Urticece. Its essential characters are : flowers dioecious ; perianth of the male flowers divided into several pieces, that of the females free, toothed ; stamens several; anthers two-celled, membranous, linear, bursting longitudi- nally ; ovary one-celled, with polyspermous parietal placentas ; stigmas equal in number to the placentas, recurved ; fruit capsular, opening at the top, one- celled, with polyspermous parietal placentas ; seeds enveloped in a membranous, finely reticulated integu- ment ; embryo straight, without albumen, its radicle turned towards the hilum. The plants belonging to this order are strong hardy herbs, with alternate compound leaves without stipules, and axillary racemose flowers. From their resem- blance to hemp, some of them receive the name of bastard hemp. They are found in the northern parts of America and Asia, as well as in the Indian Archipelago, and the southern countries of Europe. Their properties, so far as known, are bitter and tonic. The chief genera are Datisca and Tetrameles. DATURA (Linnaeus). A genus of herbaceous annuals, natives of many foreign countries, one of which the 1). stramonium has become naturalised and grows wild in England. They generally bear large white or purple flowers, but are of a short duration. They belong to the fifth class of Linnaeus, and to the natural order Solanece. Seeds. DAUBENTON I A (Decandolle). South American evergreen shrubs, belonging to Diadelpkia Decnndria, and natural order LegummoscE, Generic character : — calyx bell-shaped, five-toothed ; keel obtuse ; pod on a footstalk ; linear, with four longitudinal wings ; pod contracted between the seeds. This genus has been consecutivaly called Pisridia, Robinirr, Aschyno- mene, till settled by Decandolle as above. These plants thrive in loam and moor-earth, and are easily propagated by cuttings in the usual manner. DAUCUS (Linnaeus). Is the generic name given to the family to which the common carrot belongs. The genus ranks in the fifth class and second order of the sexual system, and in the natural order Umbel- lifercE. Some few are annuals, but they are mostly biennials : of all our cultivated culinary vegetables, no one shows the effects of domestication more deci- dedly than the carrot. It is found wild on every dry hedge-bank, every where in Britain, as well as on the continent. In its wild state, it is a diminutive plant, with an underground stein, no bigger than a small radish. In former times the daucus was held in high estimation as a medicine ; a decoction of it being considered useful as a diuretic, or solvent of the human calculus. It might be at first introduced into the garden of the herbalist for its medical properties only, and there showing a tendency to incn ase in bulk, might be in the course of time removed from the simpler's shop to the green larder of the cook. The improvement of the plant in bulk must have been gradually accomplished. It is unreasonable to suppose that a wild plant would suddenly, in any season or in any place, swell from a mere stick to a portly tuber at once. How or when it became a culinary plant is, per- haps, not now known ; but looking at the wild one on its native bank, and on the full-grown Altringham variety on the green grocer's stall, we are compelled to acknowledge that there is not a stronger proof of the ameliorating effects of culture exemplified in the whole range of vegetation. And it is not only an improved bulk of the common wild plant that has been the only result of skill and industry, many varieties have been originated by attentive cultivators ; so that there are large and late sorts for feeding cattle, and small, early, and more delicately flavoured sorts for the table ; in all fif- teen varieties, differing in size, colour, shape, or earli- ness. Cultivation. As carrots may be used at any stage of their growth, and as they are most tender when young, seed is sown at many different seasons. The first sowing may be made about the twentieth of February ; but this sowing should occupy only one or two narrow beds on a dry, finely-digged, south border. Here the seedlings may be forwarded and protected from the keen winds of March by a tliin covering of dry fern leaves or pea-straw ; and in order that such covering may not harbour slugs, snails, and worms, it should be from time to time dusted with hot lime, which will save the seedlings from destruc- tion. Carrots are also sowed about the same time on D A V I E S I A— D E A T H ' S - II E A D M () T H. slight hotbeds and under glazed frames, to get them ready for table as early in the year as possible. The principal crop of carrots either in the garden or fields may be sowed any time between the twen- tieth day of March and the tenth of April ; and suc- cessive sowings should be made in every month till September. This is, however, only necessary where young carrots are constantly required in every month of the year. The seed requires to be prepared for sowing by being well rubbed between the hands until divested of the fringe of little hooks with which they are in- vested when gathered ; otherwise they cling to each other so closely, that they cannot be equally distri- buted by the sower. When prepared, the seeds may be sowed either in shallow drills one foot apart, or broad-cast on beds three and a half feet wide with alleys between. Whichever way the seeds are sown the plants will require to be thinned to eight-inch distances apart either by hand or hoe. This thinning is usually performed in dry weather, and when the plants are two or three inches high. When this is done the crop only requires to be kept free from weeds during summer, and until fit to be taken up for storing. Carrots are usually taken from the ground about the end of October. A dry day is most suitable, because the tubers are easier freed from the earth ; and being sorted and topped, and quite dry, are then stored in sand in a dry shed or hovel for winter and spring use. Carrots thrive best in deep sandy loam, and are larger or smaller, according as this is rich or poor. Their form indicates that a deep loose soil is requi- site ; and, therefore, deep digging or trenching the ground intended for carrots is indispensably neces- sary. It is not customary to dung for this crop ; because if not trenched in very deep, the tubers are liable to be deformed, becoming forked rather than straight. The roots are liable to be disfigured by the larva of an insect which eats into the rind ; this de- fect occurs mostly in old garden ground ; and more especially to the crops sowed in March. If sowed on fresh loamy land they suffer less from the worm ; and the sowings made in April and May are not eaten so much as the early crops. The garden varieties of carrot are as follow : — Early Horn, Long Orauge, Fine Surrey, Scarlet Horn, Short Orange, Altringhatn. There are also three or four other varieties named from places where they are most successfully culti- vated. But the early horn is always chosen for the first crops, whether on hot beds, or in the open ground, and also for the last sowings in August and September ; and which latter, if they gain any useable size, require covering from frost. For principal crops in gardens or fields, the long orange and Altringham are preferred, because of their larger growth and fit- ness tor farming purposes. Some cottagers, and even professional gardeners who are situate on stiff-clayed soils, are obliged to have recourse to a peculiar mode of culture, in order to procure large and handsome carrots. On the ground intended for them, ranks of holes are made by line with an iron-shod taper dibber, fifteen inches in length ; the holes are filled with fine rich compost, and on the surface of each two or three seeds are dropped and slightly covered. When the plants have risen out of harm's way, one only is left in eiifh hole to grow to perfection. The leading radicle finds a tree course downwards, and the whole root neces- sarily receives a fine form, and arrives at considerable magnitude. DAVIESIA (Smith). A genus of New Holland evergreen shrubs, Linnaean class and order Decandria Monogyiaa, and natural order Leguminoses. Generic character : calyx bracteate, bell-turbinate, tm-- toothed. Corolla, vexillum inversely-heart-shaped, erectly rerlexed. Keel having short wings. Style straight and persisting. Pod compressed, one-seeded, lower suture dilated, and somewhat trapezium-shaped. These pretty plants thrive well in our green-houses potted in loam and moor-earth, and are propagated by cuttings struck in sand under a hand-glass and without bottom heat. DAY LILY. Is the genus Hemcrocallis of Lin- naeus and other botanists. They (the four species) are hardy, herbaceous plants of rank growth, and suit- able for borders of shrubberies, and among plants of tall growth. DEADLY CARROT. Is the Thapsia villosa of Linnaeus, an umbelliferous genus, found in the south of Europe, two species of which are considered highly poisonous. DEADLY NIGHTSHADE. Is the Atropa Belladonna of Linnaeus. It belongs to Pentandria Monogynia, and to the natural order Solanece. It is a strong growing plant, with large ovate leaves, purple bell-shaped flowers, succeeded by dark-red coloured berries, as large as small cherries. The plant is often found growing in rubbish of old buildings, and on waste ground about farm-houses. DEAD NETTLK. Is the Galeobdolon luteum of Smith, a common British plant found in moist, shady places : it receives its name from its resem- blance to a nettle, but without its stinging property. DEATH'S-HEAD MOTH. The largest species of lepidopterous insects found in England, and syste- matically known by the name of Acherontia atropos. By Linnaeus, indeed, it was placed in the genus Sphinx, but as it differs in several material points from the majority of the insects of which that genus is composed, Ochsenheimer, a German lepidopterist, separated it under the generic, or rather, perhaps, subgeneric name of Acherontia. The specific name Atropos (the third of the fates in the heathen mythology, who was supposed to cut the thread of life,) is given to it in reference to the very peculiar markings upon the back of the thorax, which, as the English name indicates, very closely re- sembles a skull or death's-head. And here we "may be allowed to notice the admirable plan introduced bv Liniurus of giving to each distinct species of animal, a name, consisting of a single word, whereby in gene- ral, some peculiarity of the creature is indicated. Before the introduction of this system it was neces- sary, in mentioning any animal, to give a short de- scription of it, as for instance, of the insect in ques- tion, it would have been necessary to speak of the •' Acherontia atrofws" as " a large moth having a skull marked upon the back." Whereas by the con- cise and elegant terms invented by Linnasus, all this circumlocution is avoided, and by the employment of a generic and a single specific word, the animal is known through the whole of the scientific world. The Death's-head moth measures from four to five inches in expanse, the fore wings are of a dark brown colour, variegated with grey, brown, and black, with a white central spot ; the bind \\n-xs are clay-Coloured Q2 244 D E A T H WAT C H. with two deutiite black fascia ; the abdomen, which is very robust, is also clay-coloured with black bands, and a black central dorsal line. The thorax is blackish grey, with a large central, pale, irregular Death's head Moth. patch, in which are two round black spots. " This grand species," observes Mr. Haworth, Lepidoptera Britannica, p. 56, " is at once the largest and the only one as yet discovered of this order of insects which is endowed with the powers of voice, almost every individual of the insect world, the hymenopte- rous part excepted, is mute. My tutor in entomology once had a male and female of A. atropos brought him alive in the winged state, both of which, when he had occasion to destroy them, uttered plaintive sounds, which he compared to the squeaking of a mouse." He then proceeds to give an account of the various sounds produced by insects, all of which we may observe are not caused, as in the vertebrated animals, by the aid of air which is respired, but by some ex- ternal apparatus designed for such particular purpose. The cry of the Death's-head moth does not appear however (as Messrs. Kirby and Spence observe) to be produced by the wings, for when they as well as the thorax and abdomen are held down, the cries of the insect become still louder ; according to Schrceter, the noise is accompanied by the rubbing of the tongue against the head, — whilst Roesel considers that it is produced by the faction of the head and thorax. Reaumur, however, thought it was caused by the friction of the tongue against the palpi, as he found that it ceased when the tongue was unfolded by the assistance of a pin ; as was also the case when the palpi were prevented from touching it : so also, on cutting off one of the palpi, the noise became more feeble. M. Passerini, however, has lately investigated the subject anatomically, and traced the origin of the sound to the interior of the head, in which he disco- vered a cavity at the passage into which the muscles are placed for impelling and expelling air : the cause, as he thinks, of the sound in question. M. Dumeril has since discovered a sort of tympanum stretched over the cavity, like, as he says, to the head of a drum (tendue comme la peau d'un tambour). Other opinions have been given by Messrs. Lorrey and Duponchel, for which we must refer to Mr. Stephens' invaluable work, vol. 1, p. 117. The caterpillar of this insect, also, if alanned, draws suddenly back, making at the same time a rather loud noise, some- what like the crack of an electric spark. Our readers will not require to bib reminded of the numerous instances in which the accidental appear- ance of insects in more than ordinary numbers has been regarded by the vulgar with astonishment and alarm : hence it is not surprising that the sudden visitation of the Death's-head moth should be regarded as ominous and as the forerunner of death. Latreille, (Hist. Nat. 14, 128,) tells us that it appeared one year in Briltany in great numbers, and as at this period an epidemic malady was niging with much violence, the mortality was attributed by the ignorant to the harmless moth. Another peculiarity connected with the history of this moth, consists in its attacking bee-hives, ravaging the honey, and dispersing the inhabitants. It is sin- gular that a creature, with only the advantage of size, hould dare, without sting or shield, singly to attack in their strongholds a people so numerous and so well armed with means of defence ; and still more singular that, amongst so many thousands of bees, it should always contend victoriously. Huber, who first noticed this circumstance, thus reasons upon the subject. — " A moth is the dread of superstitious people, may it not also exercise a secret influence over insects, and liave the faculty either by sound or some other means of paralyzing their courage. May not such sounds as inspire the vulgar with dread, be also the dread of bees." The same author states, that he was eye-wit- ness of the curious fact that the bees, as if expecting their enemy had barricaded themselves by means of a thick wall of propolis and wax, completely obstruct- ing the entrance of the hive, but penetrated by pass- ages for one or two workers at a time, thus securing themselves, by an admirable sagacity, against the in- efficiency of their weapons and their courage. " The art of warfare amongst bees," he adds, " is, therefore, not restricted to attacking their enemies ; they know also how to construct ramparts as shelter from thoir enterprises, from the part of simple soldiers they pass to engineers," instructing us that at the season when the moth appears, when too wasps and bees attack the hive, it is advantageous to narrow the entrances to the hive, so as to prevent the depredations of these obnoxious insects. The moth appears in the winged state at the close of the autumn, the caterpillar being full fed at the end of September, and a very few weeks only being re- quired to bring the moth to perfection. The cater- pillar is very large and handsome, being of a pale greenish yellow colour spotted with black, with seve- ral lateral oblique stripes of beautiful blue and green. It feeds upon the potato, as well as occasionally on the jasmine, artfully concealing itself in the day time on such parts of the stems of the plants as are best covered with overshadowing leaves, but although they feed well, and complete their transformation to chry- salis, it is difficult to obtain them in the winged state, generally dying during their pupation. " Perhaps," observes Mr. Haworth, " in a state of nature they perform their extraordinary metamorphoses deeper in the ground, and consequently in a moister and more equal temperature than most other species of Lepidoptera; and, if so, the cause of their perishing in our breeding cages is, undoubtedly, owing to their having in these cages too scanty and too dry a soil." We have known specimens obtained in the winged state, by placing them upon potatoes growing in pots in the open air, plunged into the earth, and the plant covered with gauze. The caterpillar has a curious horn upon the back, near the extremity of the body. DEATH WATCH. A small coleopterous insect belonging to the section Pentamera, family Ptinidte, and genus Anobium, which lives in timber and wood- work, and makes a slight noise, somewhat like the ticking of a watch. As in the Death's-head moth, we have here an instance of that lamentable pronene?s amongst the vulgar and uneducated, for investing tlie D E C A C E R A — D E C A P O I) A. '245 most simple and harmless objects with the most fea ful powers. Swammerdam, speaking of this insec says, " I have likewise the small beetle, which bavin firmly and strongly fixed its foremost legs, and bet and put its head through the space between their makes a continued noise in old pieces of wood, wali and ceilings, which is sometimes so loud that upo bearing it people have been persuaded that nocturna hobgoblins, ghosts and fairies wandered about then I think that this may be properly called Sonicephalui or the noisy-headed beetle." Hereon we may observ that Swammerdam's countrymen, the Dutch, do no from his account appear to be so far gone in super stition as the English, by whom this noise is con sidered ominous of death. Thus Gay, in one of hi pastoral dirges, says — The wether's bell Before the drooping flock toll'd forth her knell, Ihe solemn death-watch clicked the hour she died. And S\"ift thus satirically alluded to the same insect A wood worm, ' That lies in old wood, like a hare in her form, With ttcth or with ci:iws it will bite or will scratch, And chambermaids christen this v-.nn a Death-watch i Hccause, like a watch, it always cries click ; 'Ihen woe be to those in the hini-e who are sick, For sure as a frun they will five- up the ^host, If the maggot cries click when it .scratches the post. The insect, generally considered as the real death- watch, and of which various figures have been pub- lished in popular works upon natural history, is the Anobium tcsselatum, having the wing-covers of a dark brown colour, spotted with tesselated markings. Tliis species, however, is found in old standing trees ; whereas it is evident that the insect in question must be one which feeds in-doors upon timber worked up into articles of furniture. At the present time (the beginning of July), clicking is to be distinctly heard upon the ceiling and window-frames of houses in the country produced by various specimens of this insect (which we have figured from living specimens), and which is of a much smaller size, and more uniform colour than the preceding, being the Anobium striatum. This noise has been considered to be the call or signal by which the sexes are mutually attracted to each other, and as analogous to the call of birds. The general number of successive distinct strokes is from nine to eleven, given in pretty quick succession, and repeated at uncertain intervals ; and in old houses, where the insects are numerous, they may be heard during the warm weather almost ever}' hour of the day. The noise exactly resembles that made by beating moderately hard with the finger on a table, or rather, we should say, to scratching the top of a chip-box with the point of a pin. Mr. Stackhouse long ago observed the manner in which the noise is produced. The insect raises itself upon its hinder legs, and, with the body somewhat inclined, beats its head with great force and agility against the place on which it stands. On disturbing it, the head is drawn close to the front of the thorax, so as to have the forehead quite perpendicular ; the legs are folded up, and the antennas lodged in recesses between the head and thorax, so as to be quite imperceptible. From these, and other recorded observations, it is evident that, in its perfect state, the insect makes this ticking noise, and also that the noise is produced when (he insect is at large. We have, however, more constantly heard the noise in the interior of wood-work, and it has hence ap- peared more than probable that the noise (and it is now frequently to be heard within the wood, when the insects are arriving at their beetle state) is caused by the newly -hatched beetle eating its way through the wood to arrive at the daylight. The metamorphosis of the anobia take place near the surface, the larva taking the precaution of making its way so close to the surface, that only a very little space remains for the perfect anobia to bore through. Hence we infer that the noise is pro- duced by the action of the jaws of the beetle upon the wood, and in this manner only can we account for the fact of the ticking being heard (see Mag. Nat. History, September, 1834) throughout the winter, at a time when the insect is in the larva state, the larva itself also producing the same noise by the similar action of its powerful jaws, in gnawing away the wood, so as to leave but a feeble barrier through which the perfect insect can pierce with facility. Olivier indeed supposes that it is for the purpose of ascertaining the thickness of this barrier that the noise is occasioned. We, however, would refer it to the simple action of gnawing, which, of course, is applicable both to the larva and perfect states. There are not fewer than eleven species of beetles described by Stephens as belonging to the onus Anobium, and it is probable that the majority possess the same powers of making the licking noise above described ; but it is evident that the true death-watch must be that species which resides in old wood furniture, and which we have figured jeneath. Death Watch, natural size and magnified. There is also another insect common in old wood urniture, books, &c., both sexes of which have the ower of making a ticking noise, but not so loud as he others. This is the Atropos ttgnariut, for an account of which see our article ATKOPOS. DECACERA. In the arrangement of modern malacology constituted the second family of the first rder CryptodibrancMata ; first class, Cephalophora, in- luding the genera Loligo and Sepia. DECAPODA— Ten-legged. An order of crus- aceous animals, comprising all the larger species of ic class, and well characterised in having ten legs ; le head intimately united with the thorax, and covered y a large shell or shield ; a month, consisting of umerous pairs of organs, of which the outer pairs, in ome of the species are elongated ; but the most cha- acteristic trait consists in the existence of gills or ranchia1, more or less numerous, fixed in a peculiar avity beneath the sides of the shell. This order is divided into two sections, namely, ic Brachyura, having the abdomen shorter than tlie icrax, beneath which it is folded in repose, arid not urnished with a terminal fan-like tail : the common rab is an example of the first section ; and second e Macroura having the abdomen longer than the 246 DECIDUOUS CYPRESS -DEER. thorax, beneath which ii is not folded at rest, and is furnished with a fan-like tail. The lobster, prawn, &c. are examples of this section. See also Crustacea and Brachyura. DECIDUOUS CYPRESS. Is the Schubertia disticha of Mirbel, the Taxodium distiehum of Richard, and Cupressus disticha of Linnaeus. Richard's name is most generally adopted. It is one of our most beautiful deciduous forest trees. DECU MARIA (Linnaeus). A genus of North American twining shrubs, belonging to Dodecandria Monogynia, and to the natural order Myrtaceae. Generic character : calyx bell-shaped, limb of from seven to ten teeth. Corolla consisting1 of from seven to ten oblong petals. Stamens numerous, filaments filiform, anthers twinned : style cylindrical ; stigma a many rayed head ; capsule valveless, many-celled, seeds oblong. This plant is used in gardens for covering trellises or naked walls, grows in any soil, and is propagated by cuttings. DEER — Cervus. A genus of ruminant mammalia, having solid horns, which consist entirety of bone, without any case or sheathing of horny matter ; so that, though they are the most largely developed and splendid head-gear in the whole of the animal king- dom, they are in truth not horns but bones, covered in their early stage with skin and hair, exposed when they come to maturity, and ultimately healed off at the close of the season ; the peduncle to which the horn is attached being a complete cicatrix, and not a sore, and it soon skins over, under which skin a new horn begins to sprout soon after the old one is shed, comes to maturity, and is shed again ; and so on during the life of the animal. These annual horns belong only to the male in most of the species ; but in the rein-deer the female also is furnished with horns, only smaller than those of the other sex. The case of this species supplies us with a physiological fact, from which we can form a pretty accurate judgment of the connection which this im- mense annual production of horns, that is of the matter of bone, has with the general economy of the animals. The horns of the two sexes come to full maturity at nearly the same time, that is, as the pairing time ap- proaches, or the " rutting time" as it is called in the case of animals of this genus. As soon as this im- portant period in the economy of the animals is over, the horns of the male begin to loosen at their bases, which they do first at the circumference, and gradu- ully inward, till they drop off. The horns of the female again remain the whole of the winter, and do not drop off until her grand labour in the continuation of the race is accomplished — that is, not till after she has dropt her fawns. What purpose these horns may answer in the economy of generation, it is not easy to say ; but as they continue in the male only till pairing, and in the female during the whole period of gestation, and as they drop off in both as soon as these great labours of the year is over, it is evident that they have some connexion with the sexual system of both, and that in the female this connection is with the uterine, and not with the mammary system. In all the ruminatia, as will be more particularly explained in our general article upon that most valu- able class of animals, there seems to be a much greater concentration of the energy of the animal upon the time, the act, and the progress of reproduction, than there is in many other races, though we find it more «r less in most of those which are exclusively vege- table feeders, and it always becomes less and less ;:s the animals become more carnivorous. Though we might expect this, it is so important a fact in physio- logy, that we shall offer a passing remark upon it. — All the grazing, or vegetable feeding animals, have labour in the procuring of their food, and those which browse the thin herbage upon the thirsty plains have considerable labour ; and, therefore, they are com- pactly made, clean limbed, and fleet-footed. But not one of them requires to take its food by force or effort, to chase it as the dog does, or spring upon it as the cat. The food being fixed to the ground is peaceably taken ; and, therefore, the general habit of the animal is not a habit of excitement. Unless, therefore, the animal lives under the exciting heat of an inter-tropical climate, we can hardly suppose that there would be sufficient excitement in it to bring it up to a degree of energy required for nature's greatest work. On the other hand, the carnivorous animal is kept in a state of constafit excitement, in watching for, in coursing, in capturing, and very often in fighting severely be- fore it overcomes that upon which it feeds ; and, besides this, the food of the carnivorous animal is more stimulating than the grass, the green leaves, the withered branches, the bark, and, in the case of some the present genus, the dry lichen, upon which the ruminatia feed. It should seem, therefore, that a means is required of keeping up throughout the year, a portion at least of this energy which requires to be called forth at one period of it ; and the elaboration of horns appears to be the means by which this energy is kept up in the genus Cervus. This genus affords many other confirmations of this, in the different productions of the appendages of the head — to which, by the way, it is belter to give the name of antlers than of horns, even though the antler is strictly speaking the " brow snag " of the horn ; attire is the hunter's name for them. In proportion as they inhabit near the equator, the horns are small ; and as we come toward the polar countries they increase in size, and acquire their maximum in the extreme north, where a single pair of horns of the American elk, or moose deer, often weigh as much as sixty pounds. In the south, too, the females never have any horns, nor even in the polar countries till we come to the very last species, the rein-deer, which dwells with man, and is a most useful servant of all work, and means of subsistence to him in climates where no other vegetable feeder can exist. In the north, too, we find the deer of much larger stature than they are in warmer climates ; and this is an additional confirmation of the necessity of furnish- ing the vegetable feeders of the extreme latitudes with some permanent energy beyond that which is required for the mere purpose of feeding, in order that they may continue their race, keep their post, and preserve the balance of nature in those climates where life has, for full four months of the year, to maintain itself against cold sufficiently intense for freezing mercury, while for two or three months in the opposite part of the year, every living thing is scorched by the ardour of a never- setting sun. It is in these grand adapta- tions that we see most strikingly the oneness of the system of creation, and catch glimpses of that splendid science, that incomprehensible wisdom of design, which runs through the whole, and which preaches more eloquently than the tongues of men or of angels. Those who have not thought much upon such sub- jects may be apt to imagine that, as the horns of deer DEER. S47 are in highest perfection at the time when the ener- gies of the animals are required for the performance of those functions, at the close of which the horns drop off, the energy is most occupied in the horn, at the very same time that it is required for the other' pur- pose ; and that, therefore, the horn is a source of divi- sion and weakening of the energ}', and not a concen- tration and strengthening of it. But when they call to mind that it is during the growth, and not when full grown, that the horn exhausts the energy of the animal, that the growth is most rapid in the early Mage, and that the growth ceases when the skin comes «>ii' and the bony part of the horn is left bare, it will nt. once be seen that there is no ground whatever for such a supposition, but quite the reverse. There is something very analogous to this in the flowering of plants, which will probably suggest itself to the reader, but the introduction of it here would be out of place. With the exception of these climatal adaptations, the deer form a more distinct and perfect genus .than any of the other ruminantia, or, indeed, than almost of any group of any other order whatever; and, ' therefore, though there have been some attempts to separate them into sub-genera, the distinctions upon J which these have been founded are more fanciful than real. The species are tolerably distinct, even when they are fonnd in the same countries ; but even there ••ach species affects a different pasture ; and, there- fore, though we describe them according to their different appearances, the real distinction is one of sociality. Here we are somewhat unexpectedly brought back to the physiological doctrine which we are attempting, for the first time we believe that it has been attempted, to explain — or, perhaps, to speak more becomingly, which we are seeking to bring to the notice of those who are capable of explaining it; for the explanation points much farther than even most physiologists are in the habit of looking, or even dreaming (for they dream homewards, and not on the long view) ; and \ve >rery much suspect that, if clearly worked out with constant adherence to the facts, and the whole volume of nature open to the investigator, it would be found us wide as the entire working creation, both animal and vegetable. We may just notice that among birds, the gallina- ceous ones, and others which, though not exclusively vegetable feeders, as indeed no birds are, yet never fight with what they eat, are the ones in which the male undergoes the greatest change of plumage as the pairing season comes on. There is yet another point : among those birds which change their plumage toward the pairing time, the species in which the males are polygamous have the greatest and the richest change of feather in them. So also in the deer there is one species which is not polygamous, and in this species there is less develop- ment of horns, and also less excitement in the season of heat than there is in those where the males are polygamous. The chief ground of specific distinction in the genus ( 't-rrits is the form and production of the horns ; and this we might be prepared to expect from what has been already stated, or if we are to take the forms of the horns as an observed fact (which of course it is), it is a further argument in favour of what has been stated. Deer have been in all ages of the world among the most interesting of its wild inhabitants. There is majesty in their appearance, there is fleetness in their march ; their flesh is more esteemed than that of any other animals ; and when they are " in pride of grease" as it is called, they are in higher condition than any other animals ever are in a state of nature, or can be brought to by all the arts of the most, skil- ful cultivator. Beeves and muttons may be fatted ad nauseam; but after a moderate point, as the fat accu- mulates the flavour goes ; and a haunch of venison from the hill is, in point both of juiciness and of flavour, superior to all the beef or mutton that ever was fatted. As a proof of its superior wholesomeness we may add, that, even in the hottest weather, venison is hardly ripe in double the time in which beef or mutton would be putrid. The common-blue bottle fly tells tales in this respect : that insect is attracted by the scent of incipient putridity, as blue bottles may be observed most plentiful about those butchers'-shops where both the shop and the meat are in the worst, condition. The fleetness and watchfulness of deer, the bold- ness with which the males turn on their pursuers when pressed to extremities, and their value when caught, have m^de them at all times the most favourite game with the hunter, both for killing1 with missiles in the woods, and for running down by dogs in the open places. Indeed, it is highly probable that it was the deer which taught mankind the use of the bow in many countries in the earlier periods of their history, though Canning in his exquisite satire, " The Progress of Cruelty," bestows the honour of having suggested this invention upon the pig — in his eager desire to eat which, the wild man applied the barken string to the bended branch, laid the pointed reed across, drew with all his might, let slip, and Twang sounds the string, the hissing arrow flies, And darkness seals the gentle porker's eyes. While great part of England was covered by exten- sive forests of timber, the shooting of deer formed, in the season, the occupation of kings, and feudal lords and their vassals, and, except in trying their weapons upon each other, it was almost their only amusement. It also formed a stock theme with the romancers and poets of the time ; and, though it is partly true and partly fabulous, there are few of the remains of the lore of the middle ages which has had more readers and admirers than the story of Robin Hood and his band in Sherwood Forest. Nor in the more open parts of the country was the wholesale slaughter of the deer by driving in one way or other a less cele- brated employment ; and when " the stout Earl of Northumberland*' wished to bring the feud with the Douglas to an issue, he had recourse to a deer-stealing incursion upon the grounds of the latter : — To drive the deer with hound and born, Earl Percy took his way; The child may rue that is unhorn, The hunting of that day — as is said and sung in the very beautiful and truly national ballad of Chevy Chase. Innumerable other instances might be cited to show the importance which our forefathers attached to these animals ; and it is probable, nay it is certain, that to the fondness both of men of rank and of men of no rank for deer, we are indebted for the brightest ornament not only of Eng- lish literature, but of the literature of all nations. — William Spakspeare was a deer stealer, and as such was driven from his native county to seek shelter in the British metropolis, and make his way there the 248 DEER. best way he could ; and, from the miserable doggrel in which he vented his indignation against those who had punished him, there is every reason to conclude that if Shakspeare had remained in the country, he never would have been the author of one readable line Therefore, the deer may be said to have given us more than man by force of armies, or by strength of reasoning, could have given us — it has given us Shakspeare. Deer belong more to wild than to cultivated nature ; and more to the rude and early stages of countries than to the more polished and advanced periods. They are also inhabitants of northern climates rather than of cen- tral ones ; and in the extreme south are unknown as na- tive animals. They are found throughout the continent of Europe and Asia, and in the more proximate Asiatic isles ; but there is not a vestige of them or of their remains in any of the islands of the great South Sea, in Australia, or in Africa, as native animals. They are found, indeed, in the north of Africa, on the slopes of the mountains of Atlas, but there is not the least doubt that though now naturalised there, they were originally imported : there is not a vestige of them to the south or the east of the desert of Sahara, though all that part of Africa swarms with antelopes ; and the southmost of the Asiatic isles in which they are met with is Timor, where the species is very small, and by no means abundant. In America, their grand head-quarters is the north, though they continue downwards along the mountain slopes, and in the extensive forests, a good way into South America ; but although there are several species in that part of the western continent, it does not appear that there is even there any one which can, with propriety, be called an Antarctic or southern deer. Thus we may regard them as being properly animals not merely of the northern hemisphere, but of the extreme north, for the species which are found there are of far greater size than those farther to the south, and also more abundant in numbers. Although some of the species are Comparatively tame, and one in particular, the rein-deer of the north of Europe, is in a state of complete domestication, yet, as a genus, they cannot be ranked among domestic animals, and they fade away before the procuress of cultivation. In the state of nature, they, generally speaking, frequent grounds which are rather rich, and most of them either the woods or thoir margins. Some of them are fond of marshes, and the banks of streams, and even take to the water at a certain season of the year, and all of them can swim. In locality and food the species differ a good deal, so that we shall mention these particulars along with our notice of the species themselves. The following are the generic characters : eight incisive teeth in the lower jaw, but none in the upper ; no canine teeth in most of the species, though some have them in the upper jaw ; six grinders above and below on each side ; head long, terminated by a muzzle, and with the upper lip more or less elongated and prehensile in the different species ; the ears very large ; the eyes bright and clear, with the pupil elongated ; sub-orbital sinuses, or slits under the eyes, in the greater number; tongue soft ; no gall-bladder; the female with four mammae in the groin. As, in the former part of this article, our physiolo- gical remarks on the use of the horns in the economy of the animal took our attention from the description of them, and as that is a sort of technical matter, which it is sometimes reckoned unclassical not to know, we shall mention a few of the particulars The ring of irregular protuberances which surround the horn at its base is called the burr ; the main stem of the horn is called the beam ; the divisions on the upper part of the beam are called branches, or snags ; and the branches next the brows, of which there is one, two, or three, according to the species, and there are occasionally, but rarely, some irregularities in the same species, are called antlers ; and the first of these is called the brow-antler, and the second the bezantler. The rudimental horns, which appear the first year, but they do not make their appearance till the year is out, that is, till the summer after they are dropped, are called prickets, and the little pro- tuberances on them, which mark the rudimental antlers and branches, are called dags, which name is also sometimes given to the prickets. In some of the species, and it is most remarkable in the southern ones, the beams and branches are all slender, and nearly round in their sections ; but in other species, and most conspicuously in the most northern ones, the beams, and in some also the antlers, have flattened extremities, which are called palms ; and when the beam is much palmated, the terminating branches are usually short snags. In the stag, when full grown, snags appear on the front edge of the upper part of the beam, or the forward branch, in which case the animal is called a " fore-hand stag." During the time of its growth the horn is sentient, and bleeds when wounded, and a wound upon it will sometimes occasion the production of an additional snag. The following is an account of the progress of the horn : — At first a slight protuberance appears covered by the skin, where a great number of vessels are spread, for a considerable degree of heat is per- ceptible under it. Soon the protuberance rises, and in some species branches off into ramifications. After a certain period, the development is arrested, the skin, which had continued to stretch and extend over the whole production, loses its heat, dies, becomes dry, and finishes by tearing off in rags. At length the horn itself becomes detached, and falls ; a slight hemorrhage follows from the skin, or the part of the frontal which sustained it. In the course of twenty- four hours, in healthy deer, the vessels which emitted the blood are closed, a thin pellicle covers the wound, and immediately the reproduction of a new horn becomes apparent ; the extremity of the vessels swells, a burr expands around the base where the late horn stood, resembling those on the bark of trees when they have received wounds which begin to cicatrize ; the burr widens, while the vessels which proceed from the bone deposit osseous matter. Hitherto the development of the horn has been uniform, the vessels have extended in a certain direction, always the same in each species ; but when they have arrived at a certain point, they separate, some continuing as before, while others turn into new, but always invariable directions, if no accident impedes them. The horns of each year come up with a branch or snag more than in the preceding year, so that they serve for a sort of register of the age of the animal. No male deer is said to be " of the first head," till there are five snags or branches ; and after that he is counted, and ranks in hunters' honours by the number. When he ia " a stag of ten," he is accounted a noble animal. In giving an account of the various species of deer DEER. 240 we shall take them as nearly as possible in the order of their locality from the north southward, subdividing them at the same time into a sort of three groups, which, however, are also local groups — those which are found both in the eastern continent and in America — those which are found in the eastern con- tinent only — and those which are found in America only. I. DEER COMMON TO BOTH CONTINENTS. REIN-DEER (Cervus tarandus). This species is the Keen of the Laplanders, and the Carabou of the natives of the extreme north of America. There have been doubts raised as to its identity in the two continents, but these doubts do not appear to be well founded, as in both countries the manners and general appearance of the animal are the same. It is the mqst polar of the whole genus, subsisting where no other ruminant animal could subsist, arid upon food which could support scarcely any other animal ; and it is as gentle in its manners as it is endearing, being- all in aTl to the Laplanders, where no other animal can be of use to them, either for labour, or, in as far as ruminant animals are concerned, for food. In the more northerly parts of Europe it is alone, but in the north of America it blends with some of the other species. This is not, however, owing to any difference in the animal, but to the difference of the countries. The winter in Lapland is much milder than in the north of America, even in latitudes much farther to the south ; and the Lapland summer is not so burning as that of America ; therefore there is a difference in the seasonal shifting of the quarters of the animal. In Lapland it goes to the mountain in summer, and descends to the valleys in winter ; and as the sea is not frozen even at North Cape, the cold of the Lapland winter is not excessively intense. At the north of America, on the other hand, the sea is com- pletely frozen over, the cold is extreme, and, from the depth of the snow, food for the rein-deer there is altogether inaccessible. Iu consequence of this, it migrates more to the south, or farther in latitude than in Europe. Rein-deer. Rein-deer vary considerably in size ; and we have this proof, that though they are docile, and breed in a domestic state, that state is not quite congenial to them ; that they are always of more diminutive size when domesticated than when wild, even though they should happen to be better fed. In the wild state, the full-grown male is equal in size to the full- grown stag, or perhaps even larger, but its legs are more clumsy, its body is more squat, and, altogether, it is a much less graceful, as well as a much less courageous animal, than the stag. In the general shape of its body, it bears some slight resemblance to a calf. The neck is very short, the head carried in a line with the back, and, altogether, the aspect of the animal is heavy. Its body is covered with two sorts of hair, one having considerable resemblance to the hair of the rest of the genus, and, like that, having a narrow neck at the insertion of each hair into the skin. This form of the individual hairs is, so far as we are aware, common to the whole genus, and might, on that account, be made a character, as it is not met with in almost any other animal. The hair has something the form of an old-fashioned lance, which was thickened toward the handle, to give it stiffness, then had a narrow place for the hand to grasp, and beyond that another thick portion for fixing, or setting on the rest. In the hair of the deer the latter portion is inserted in the skin, a small part close to the skin is a mere filament, and then the remaining, or principal part of the hair, is thick, and tapers to a point. In consequence of this formation, the hair easily separates ; but it lies flat, and does not stand on end when the animal is excited, as hairs do which are thick at the roots. This answers to not unimportant purposes. In the first place, when the animal is exposed to rain, the hairs fall flat over each other, and throw off the water like a roof; and in the second place, these flexible-rooted hairs give way to the air much better than stiffly-rooted ones would do, and, in consequence, the animal is less fatigued while making its escape from its enemies. Besides this hair, which is common to all the genus, the rein- deer has short woolly hair among the roots, as is the case with most animals of very cold climates. In winter, there is a third kind of hair, which is long, only thinly scattered over the upper part of the body chiefly, and of a whitish colour. The colour of the rein-deer hardly admits of any definite description, for there are great varieties even in the wild state, and, as we might expect, the colours of the domesticated ones vary almost as much as those of cattle. There is what is understood to be a sort of typical marking, namely, brownish, with white, round the mouth and the horns, and also on the shoulders, extending in a bar to the flanks and rump, and under the tail, and white also round the hoofs. The belly, and insides of the limbs, are also generally white ; but some of the wild ones, and many of the tame, are white all over. The fawns are generally brown on the upper part, reddish on the under, and dappled with white spots. The horns of the male are generally much pro- duced and broadly palmated, being sometimes as much as four feet long ; those of the females are much smaller, and have the palms narrower. No fixed account or representation can be given of the form of the fawns, but in general the beams are thrown back from the forehead, and then bent forward with a considerable sweep. On their front sides they bear two branches, which are sometimes simple antlers, and at other times palmated or snagged. The remaining snags are on the back of the curves. The males drop, or, as it is called, mew their horns about the month of November ; and the females, when not in fawn, drop theirs at the same time ; but, 230 D E E It. as already mentioned, the females which arc in lawn do not drop their horns till they have brought forth. It' the male is mutilated, it has the effect of making the horns remain on for one whole year ; but after this they are shed at the same season as those of the entire animals ; and, as is the case with cattle, they increase rather than diminish after the operation. This might be expected, inasmuch as the energy which is divided in the entire animal goes wholly to the formation of horns in the other. The rutting season is in October, at which time the males growl something in the same manner as fallow-deer. They have an apparatus in the throat, which we believe has not been detected in any other of the genus, namely, a membranous sac, between the thyroid cartilage and the os hyoidcs, opening by a slit into the larynx, and capable of being inflated with air, somewhat similar to that in the howling monkeys ; but what effect this may have on the sounds which they utter has not been ascertained. The fawns are usually dropped in May, they are one or two, but rarely three ; when dropped they have rndimental horns, and these become snags an inch in height in the course of two weeks, so that in this respect they differ from all the deer of warmer climates. They are excellent swimmers, and ride so lightly in the water, that, half their backs are above the sur- face ; their broad feet strike with great force, and impel them so fast in the strongest currents and across the broadest rivers, that a boat well-manned can scarcely keep pace with them. When defending themselves, they strike downwards with the horns, but do not gore ; they kick with violence, and repel the wolf with success ; but their most dangerous enemy is the glutton, who is reported to drop down upon them from the branch of some tree while they are off their guard, and both that animal and the bear are apt to watch in trees, and drop down upon them as they pass. The feet of the rein-deer pro- duce a cracking noise when they run, by the hoofs striking against each other. Rein-deer are remarkably well provided with the means of finding their way. The nictitating mem- branes of their eyes move with nearly the same faci- lity as those of birds ; so that they can proceed directly against the heavy falls of snow which are so common in that country in the early part of the win- ter. Their sense of smelling is equally acute ; and by that alone they can not only find their way in the darkest nights, but conduct their master with perfect safety in his sledge, at times and through places where human sagacity would be utterly at fault. There is no animal, indeed, so serviceable to man in any country as the rein-deer is to the Laplander ; and if he were deprived of it he could not by possi- bility exist. With its assistance, however, his con- dition is more comfortable than one would readily suppose, and there is nothing which he could substi- tute in the place of this most useful animal. It feeds upon those plants which form almost the extreme of vegetation,— the buds and twigs of the small arctic shrubs, and the lichens which grow abundantly where nothing else will grow ; and thus he does not require to sow grasses, prepare meadows, or cultivate any sort of vegetable, but may be said to obtain the labour of this excellent servant for nothing. All that he has to do is to protect his little herd from the bear and the glutton, and guide them to their changes of pas- ture as the different seasons of the year require. In the wild state they are gregarious, and when domes- ticated they are perfectly social, very mtich attached to eacli other, and obedient to the orders of ilie herds- man ; an elder of the herd generally takes the lead, ml the rest follow him with a most willing obedience. The herdsman teaches this leader to obey his whistle, and the rest will follow after, at almost any signal, such as a stamp of the foot, or even a look. They draw the sledge over the snow with great rapiditv, and apparently with less fatigue than any other ani- mals of draught. No doubt the hard and smooth surface of the snow is a sort of railway, or at least bears some resemblance to it ; but still it is no small feat for two deer to draw a man in a sledge over "three skies" of the Lapland mountains in twenty- hours. A " sky" is a mode of estimating distance understood in most mountainous countries ; it was once very general in the islands of Scotland, and is still used in those places where there are no roads. It means a new horizon, which the traveller obtains every time that he comes upon the top of a new hill. These skies are, of course, of very different lengths ; but from the character of the country the average length of three taken together may be reckoned at not less than one hundred miles ; and we are not aware of any other means by which a man could be drawn the same distance over snow during twenty- four hours of a sunless night. But this is not the only advantage which the Lap- lander derives from the rein-deer : the flesh of the animal is the most substantial part of his food, and its milk serves him in various ways. It is used recent ; it is coagulated into cheese, the whey is used for drink ; and we believe in some instances fermented and distilled into a liquor something analogous to that which the Tartars make from the milk of the mare. The skin of the rein-deer, which is warm and strong and pliant, serves for a clothing, for blankets, for covering the sledge, and for almost every purpose for which we apply cloth or leather. The tendons, which are very tough, furnish thread ; the horns are manu- factured into a variety of domestic utensils ; and even the intestines of the animal have their domestic uses, while the tongues, which are considered luxuries in most countries, give even the poor Laplander an ex- port trade, and make even him a citizen of the world. There is no country in Europe so much infested with the plague of flies as Lapland, especially in the swampy and shady places, where the gnats are almost as tormenting as the musqnitoes in tropical countries ; to escape from these the Laplander and his herd take to the open hill in the summer ; but even there the animal is not secure from insect annoyance. Even in the most elevated and airy of its mountain pas- tures, the rein-deer gad-fly (CEstris tarundus, Linnaeus,) finds out the herd, and the hum of a single insect is sufficient to throw the whole into a state of the greatest agitation. The object of the fly is to deposit its eggs under the skin of the animal, which it gene- rally succeeds in doing ; and it is said to be when the rein-deer are about two years old that they are most annoyed by this insect. Estimated by this, his most valuable possession, the Laplander is often a man of no small wealth, for his herd sometimes amounts to as many as a thousand ; and as two is the average production of each, and the number of females far exceeds that of males, this herd furnishes him with an abundant supply of all the Elk D E E R. 251 necessaries of life ; and from the different numbers which different individuals possess, and some being without any, there are grandees and paupers in the wastes of Lapland, as well as in the most fertile and thickly populated countries in the world. In Lapland properly so called, and in all the country northward to the Gulf of Bothnia, we believe that there are now few rein-deer in a wild state, if, indeed, there are any ; neither are they met with in the southern or lowland parts of Sweden ; but in the central province of that country they are still to be found in considerable numbers. It does not appear that the species ever existed in Europe to the south of the Baltic, though as we proceed eastward and the cold extends farther to the south, we find rein-deer farther to the south also. They range east- ward over the whole continent to Asia, and north- ward to all the isles of the Frozen Ocean, whose icy plains afford a ready passage ; and from the struc- ture of their feet they are well adapted for making- rapid way upon the ice ; and, indeed, it forms a better passage than the land, as it is more level, and always covered with a coating of snow. They are met with in Spitzbergen, which is near the eighteenth parallel of latitude, where man, notwithstanding his flexibi- lity to climate and his mental resources, is unable to endure the winter. On their migrations rein- deer no doubt frequently meet with their polar neighbour the white bear ; but we believe he is unable to come up with him on the ice. The circumstance of no trace even of the bones of the rein-deer being found in a fossil state in central or southern Europe, decides that in all ages of the world, this has been strictly a polar animal ; and the fact of its seeking the verge of the Frozen Ocean, and jour- neying upon the ice, proof against the very extreme of the winter's cold, readily accounts for the fact of its being found both in Europe and in America. The continents approach one another very closely on the side of Siberia ; and even in the summer months the ice is so little way to the northward of Behring's Strait, that even then it would be no very arduous march for a reindeer to pass from Asia to America, or the reverse. It is probable, however, that the intercourse, if it is still kept up, takes place during the winter ; because at that season the animals descend, while in summer they seek the elevated spots. These circumstances and the facts which we have mentioned of the variations of colour to which rein- deer are liable, clearly establish that though there may be variations in the average colour of the rein- deer of Europe, and the Carabou, as it is called in America, that they are the same identical species. The horns are said to differ at least in some of those which have been considered as varieties in America ; but these appendages differ so much even in the same herd, and sometimes in the same animal, for the one horn is often very differently shaped from the other, that no species or variety can be founded upon any variation of these. Whether the rein-deer passes along the polar ice from Spitzbergen to Greenland, we have no means of ascertaining. It is possible, though not very likely, that with the exception of this one break of its range, this most polar of all the rumi- natia has unbroken command of the entire circuit of the earth ; and on this, its peculiar locality, as well as for its usefulness to man, in the land of his greatest necessities, the rein-deer is one of the most interesting of animals. Before we pass to another species it may not be amiss to notice merely for the purpose of showing how unlikely it is to be true, that some naturalists have described the fossil horns found at Etampe in France, to which horns an animal has with most gra- tuitous ingenuity been added, under the name of Cervus Guetardi, as belonging to the reindeer ; but from what we have said of the variable nature of the horns, as well as from what we may call the demon- stration by the late Cnvier, who was at once the most learned and the most cautious judge in such matters, there seems decidedly to be no truth whatever in the assertion. THE ELK (Cervus alces). This is the next in order in geographical position, its locality lying immediately to the southward of that of the reindeer, and the two bivoculating with each other on their confines in the eastern continent, and still more in the western. The elk, which was once pretty numerous in central Europe, is now rare in that quarter of the world, though it is still not unknown. In America it is much more abundant, and inhabits further to the south, its head-quarters being the vicinity of the great lakes, and the forests on both sides of the St. Law- rence ; the whole of Canada in fact with New Brunswick, and also westward, at least as far as the RockyMountains.which come down upon the northern ocean, or rather the Polar Sea to the westward of the debouchure of Mackenzie's River, in about 135° west longitude. It is not mentioned that the animal has occurred to the westward of those mountains, and, though not impossible, it is not by any means so pro- bable as that the reindeer should be there ; for besides the elk having a less polarly situated locality, its habits are different. The reindeer is adapted to the dry lichen-clad hill in the summer, and to the snow in the winter ; while in summer the elk is more in the marsh, and sometimes actually in the water feed- ing on the submerged grass, and ever and anon blow- ing somewhat like a whale, and in winter it is more in the forest. Still there is no reason to suppose that there is any specific difference between the elk, or moose deer as it is called in America, and the elk of the eastern continent. No doubt black elks and reddish elks, and sometimes also white elks, have been described ; but the elk is subject to very considerable changes of cojour with age, the very old ones being apt to turn almost black ; while the young ones are chestnut coloured, and there is little doubt that the white indi- viduals are albinos. We cannot resist quoting the following very accu- rate and highly graphic description of the elk, from the pen of Colonel Hamilton Smith, whose monograph on the ruminantia forms the greater part of the fourth volume of the English translation of Cuvier's Animal Kingdom, published in the name of Griffith, which monograph most justly called forth the highest eulo- gium from the illustrious author of the original work. " This animal is the largest of this genus, being higher at the shoulders than the horse ; its horns weigh sometimes near fifty pounds ; accordingly, to bear this heavy weight, its neck is short and strong, taking away much of the elegance of proportion so generally predominant in the deer ; but when it is asserted that the elk wants beauty or majesty, the opinion can be entertained by those only who have seen the female, the young, or the mere stuffed speci- mens ; tor we who have had the opportunity of view DEER. ing the animal in all the glory of his full-grown horns, amid the scenery of his own wilderness, no animal could appear more majestic or more imposing. It is, however, the aggregate of his appearance which pro- duces this effect ; for when the proportions of its structure are considered in detail, they certainly will seem destitute of that harmony of parts which in the imagination produces the feeling of beauty. The head, measuring above two feet in length, is narrow and clumsily shaped by the swelling upon the upper part of the nose and nostrils ; the eye is proportionally small and sunk ; the ears long, hairy, and asinine ; the neck and withers are surmounted by a heavy mane, and the throat furnished with long coarse hair, and in younger specimens encumbered with a pendu- lous gland ; these give altogether an uncouth charac- ter to this part of the animal. Its body, however, is round, compact, and short ; the tail not more than four inches long, and the legs, though very long, are remarkably clean and firm ; this length of limbs and the overhanging lips have caused the ancients to fancy that it grazed walking backwards. The hair of the animal is coarse and angular, breaking if bent." The elk is an inhabitant of northern latitudes ; in Europe between the fifty-third and sixty-fifth degrees, making a part of Prussia, Poland, Sweden, Norway, Finland, Lapland, and Russia. In Asia it is found farther south, from thirty-five to beyond the fiftieth, spreading over Tartary, and abounding in Japan, if indeed the denomination of elk is not misstated for that of a rusa, or an undescribed species. In America it resides between the forty-fourth and fifty-third de- grees, round the great lakes, and over the whole of Canada and New Brunswick. Its movements are rather heavy, and the shoulders being higher than the croup it does not gallop, but shuffles or ambles along, its joints cracking at every step with a sound heard to some distance. Increas- ing its speed, the hind feet straddle to avoid treading on its fore-heels, tossing the head and shoulders like a horse about to break from a trot to a gallop. It does not leap, but steps without effort over a fallen tree, a gate or a split fence. During its progress it holds the nose up, so as to lay the horns horizontally back. This attitude prevents it seeing the ground distinctly, and as the weight is carried very high upon his elevated legs it is said sometimes to trip by treading on its fore-heels or otherwise, and occasion- ally to give itself a heavy fall. It is probably owing to this occurrence that the elk was believed by the ancients and the vulgar to have frequent attacks of epilepsy, and to be obliged to smell its hoof before it could recover; hence the Teutonic name of elcud {miserable), and the reputation especially of the fore hoofs as a specific against the disease. During the winter months the elk resides chiefly in hilly woods, in snowy weather seeking the covers, and in clear the open spaces. In summer it frequents swamps on the borders of lakes, often going deep into the water to escape the sting of gnats, &c., and to feed without stooping. Its usual food in winter con- sists of the buds and bark of button-wood, spruce, and juniper pines, birch and maple, and under the snow it seeks stink wood (Anagyrisfcetida) and mosses, but this is always with difficulty, for then it is obliged to spread the fore legs, or even it is said to kneel. The branches of trees it turns down with the horns very dexterously ; but to get at the ground we have been assured by Huron and the Canadian hunters, when the snow has fallen only a foot or two in depth, that the herd, led by an old male, shovel it back, and throw it over their heads, the snow falling on either side, as it slides from the inclined planes of the back of their horns ; meantime the fore feet of all are equally engaged in striking it from under them. During a part of the year the herd consists of an old female, two adult females, two young females, and two young males; but during the snowy periods, at least in America, one or more adult males are cer- tainly among them, very old males alone keeping aloof until the rutting season, unless the winter be very severe. Several of these families keep near each other, and in very cold weather they seek cover together, and remain closely pressed against each other, or trot in a circle till they have beaten the snow down. When the rutting period commences, which is about the beginning of September, the old males seek the females, and expel the young, who are obliged to keep aloof while the animals remain in heat. At this time they will swim rivers in pursuit of the females, or after them to remain concealed in some of the Lake Islands. The males are then very pugnaceous ; they bellow often and sink in flesh. The gravid females bring forth about, the middle of May, at first one, but ordinarily two calves, of a brown red colour. These are so simple and void of fear that in the first months they are easily taken, and if in the water, where they willingly go to avoid the flies, they will suffer persons in a canoe to come up to them and take them by the head without appearing in the least frightened. The dags, prickets, or incipient antlers are the first year not more than an inch in length ; the second they rise to a foot ; the third they are forked, and the fourth they assume six snags and are somewhat flattened ; the fifth year the blade is still small, but their expansion from that time forward is uniform, though it does not appear that the number of snags ever exceed twenty-eight. In a very large specimen which we saw shot, there were twenty-two, the length from the head to the tip twenty-seven inches, and from tip to tip across the horns three feet six ; the two lower snags on each side separated by a deep indenture : the weight about thirty-three pounds. Old elks shed their horns in January and February, and, if lean from a severe winter, in March ; the younger later, till the month of May. They are again completely restored in the former by the end of June, and in the latter in August. " An elk killed in Sweden is said to have weighed 1200 pounds, but this must have been a very extra- ordinary animal ; their height is about six feet. A white specimen from Swedish Lapland, in the Munich Museum, five years old, is six Rhineland feet at the shoulder. A female figured by Mr. Heriot was seventeen hands high ; the large male above alluded to was scarce four inches more, or about six feet, but he was very deep at the shoulders. Another, whose antlers were still more deeply indented at the base, that is with the parts corresponding to the brow and bezantlers of the stag, separated from the main blade by a deep intersection, was not more than seventeen hands and a half high. His head, from the nose to between the ears, two feet three inches ; distance between the eyes eight inches ; length of the ears nine inches and a half ; the lower branches or snags were bifurcated and thirteen inches long, and their united amount was seventeen, with the rudiment of D E an eighteenth. The hunters named him a black moose, and from the greater length of head in pro- portion to his height, and the particular form of the horns, insisted that this was a different species from the brown. There is however no character sufficiently distinctive to claim our assent to this assertion, for it is known that considerable variation in the horns occurs from various causes, although it must be ad- mitted that the almost complete separation of the lower parts into the form of branches is a very pro- minent character in most if not all the American specimens, while a similar formation is rare in those of Europe, but the colours of the hair differ with the season ; and if this specimen belong- to a different species, both would be of that species, the result proving only that the European is not of the same. The two here mentioned were dark, almost black, with grey hairs intermixed, but that with the largest horns had the greatest intermixture of grey ; they were killed on the borders of the Saquenai, in Lower Canada, where both they and a herd of buffaloes were considered as strangers. The darkest was shot in September, and the grey in November, which may account for the difference of colour. " During the time that their horns are sprouting, the animals remain most in willow covers, returning to the evergreen woods when they are restored ; their period of life does not exceed twenty years. " They are hunted in North America chiefly during the early part of winter, and towards the spring. While the snows are not deep they are not easily attacked; but when they begin to harden, and the hunters run on snow-shoes, they endeavour to turn the game towards ravines, or where it is drifted deep. The Huron hunters have assured us that when this is effected he is sure to be soon entangled, and to flounder in it ; but that they must be on their guard, and run instantly upon the deep snow to fire at him as he turns, because he will endeavour to double on his own track, and charge all that are then in his way. When first discovered, he is often found sitting on his hams like a dog, voiding his urine before he rises to escape. Against the bear and the wolf, he stands at bay with his horns, acting offensively only with his fore or hind feet ; his kick is very powerful and quick ; it is said that a small tree is splintered by it. " The Indians are great admirers of the flesh, to us it appeared superior to the stag's ; but under the cir- cumstances which admit of this kind of banquet, it may be doubted whether a similar judgment would be passed in the comforts of a home ; the nose and the tongue are admitted to be the best parts. Mr. Pennant states that they were once used to draw sledges in Sweden, but that it afforded to malefactors the facility of escaping, and that therefore the use of them was prohibited. The hide furnishes excellent leather and buff skins for belts." It has sometimes been alleged, that the very large deers' horns which are found abundantly in the bogs of Ireland, and sometimes, though more rarely, in similar formations in Britain, are horns of the elk ; and it has thence been inferred that at one time the elk was very plentifully found in the former island, and by no means rare in the latter. But there is no reason to conclude very dogmatically from the horns themselves, because, as we have already said, they are subject to great variations even in the same country and at the same time ; and therefore we can E R. 258 satisfactorily draw no conclusion from them as to what may have been the animal whose remains are so common in these deposits. But we have conclu- sive evidence that the animal to which those horns belong, and which must have been at least as large as a cart-horse of the present day, was a stag and not an elk ; because the skeleton has been found, and the relative proportions of the bones are exactly those j of the stag ; but whether of the stag which is still found in the old continent, and which has degene- rated in consequence of change of climate in the lapse of centuries, or of some more gigantic variety which is now extinct, we have no means of ascertaining ; and therefore it would be idle to offer any conjectures on the subject. That Ireland and many parts of Scotland, more especially the western islands, and the isles, have undergone a very remarkable climatal change is cer- tain. They are now almost entirely denuded of tim- ber, except a few wretched copses of underwood, and a few artificial plantations ; and in both, black or red peat bog has come in the stead of what once were forests of the most gigantic trees. When those forests were in their prime — and glorious forests they then must have been, for the writer of this article has traced the remains of a single tree full 150 feet in length — when they were thus in their prime it, is natural to suppose that they were inhabited by deer worthy of them ; and that from whatever cause, or by whatever catastrophe, the goodly forest and its gallant inhabitants have faded away. It is generally said that the invaders of Ireland wantonly consumed the forests with axe and fire-brand, and as wantonly exterminated the deer, but this wants confirmation ; and besides it does not come within the pale of natu- ral history, and would not explain the phenomena lit question although it did. Wrhen we look at the grand features of the natural world, we may put aside the small results of man's working ; for there is a maturity and a decay in certain states of countries which man cannot greatly, or perhaps even sensibly,. either accelerate or retard. Besides, we know of no such catastrophe in the parts of Scotland to which we have alluded"; and there we find a few lingering rem- nants of the forest which tell us of its former existence, and that it has yielded to the powers of nature, and not to the hand of man. In many places there are the roots of yews with a small circle of the external or last formed wood still undecayed, and sometimes with green foliage the size of a feather upon some por- tion of the ample circumference. These were in the rich bottoms no doubt, but at all events they are now in the wilderness ; and some of them measure fifteen or even eighteen feet across, so that they must have been giants in their day. Besides, in situations which are too bleak, and beaten by the winds and rain of the Atlantic, for suffering fungi to sprout and moss to accumulate for (such are the beginnings of a peat bog), there are still immense trunks lying bleaching, white and sapless, and unfit for affording nourishment to even the smallest fungus which can grow upon a fallen tree. This is not, however, the place to enter upon such subjects, though it is difficult to discuss the natural history of deer without at the same time thinking of the progressive history of forests, and being carried back in imagination to times when our country had far more of a natural majesty in it than it has at present, notwithstanding its arts and its wealth ; and though our habits are such that we «54 DEER. would not willingly part with these, yet it is refreshing sometimes to glance back in imagination to those glories of the land which are gone for ever, until some convulsion of the globe shall depress our islands to " the oozy bottom of the deep," and let them rest there during the night and sleep of lands until another convulsion of nature shall again upheave them, like a giant refreshed, and fitted anew for giant plants and gigantic animals. II. DEER OF THE EASTERN CONTINENT. The two species which we have enumerated, namely, the reindeer and the elk, are the only two which can be considered fully established as inhabiting both the eastern continent and the western ; and though the elk inhabits more southerly and in richer pastures than the reindeer, yet it is sufficiently far in the north for allowing the supposition that it may have passed from continent to continent upon the ice. Those which remain to be considered are the deer of temperate and of warm countries, which inhabit too far to the south for interchanging between the continents ; and though there are exceptions as regards particular places, which are explainable by the different charac- ters of those places, yet we may in general say that the size of the animals, and especially the develop- ment of the horns, diminish as we approach the southern limit. In most countries, however, which are adapted to the race, and from which that race has not been ex- terminated by natural or artificial means, we may say that there are in general three species of deer, one affecting more the forests, another the open savannahs or rich plains, and the third the more elevated and airy wastes. We may thus style them according to their pastures — forest deer, field deer, and hill deer. We have types of all the three in this country, though it is possible that the field deer, the one with which we are most familiar, but which partakes not of the majesty of him of the forest, or of the airy beauty of the mountaineer, may be an importation. We shall first notice these three in their order, and then briefly mention the foreign varieties. THE STAG (Cervus ekiphus). This is the deer par excellence in all works on " the noble art of venerie," and in all allusions to the bold foresters of merry England. It is the red deer, and the male is called a hart, and the female a hind. The characters are, the horns round in their section, furnished with three antlers on each beam, turned to the front, and curved a little upwards ; then the top of the beam terminates in a number of snag?, all at nearly the same elevation, and increasing in number with the age of the animal. In summer the general colour is yellowish brown, with a black bar across the shoulders, and a row of pale yellow spots on each side. In winter the colour changes to a uniform red- dish brown; but the hinder part of the rump, the tail, and a small portion of the feet above the hoofs (which we term the fesses), are always of a pale yellow. — Both sexes have canine teeth, which are rather long, and bent in the male, but the female has no horns. — The young fawns are of a rich yellowish brown, dap- pled with white spots ; and it is from their ground colour that dyers give the name of fawn to a peculiar shade of colour, intermediate between brown and yellow. The colour deepens much with age ; so that in winter the old stags are nearly black ; but they retain the mark on the crupper and fesses. The stag is by much the largest of European deer, and the probability is, that the large horns above alluded to have belonged to the very species which is still met with in some parts of our own country, and more abundantly on the continent of Europe, where forests are far more extensive, and have been less dis- turbed. The rutting time of the stag is in September, the young one being driven off by the mothers in August, and during this season the males are in such Stag or Red Deer a state of excitement, that it is not only highly dan- gerous to approach them, but the}' sometimes ill-treat and even kill the females. The hind goes a few days more than eight months with young, and drops her single fawn, for she has rarely two, in the month of May. It used to be fabled, that the stag wa« remark- able for length of life ; but it does not appear that it lasts longer than about twenty years. It is found less or more in all places of Europe, where there is cover adapted for it, except in the extreme north and in very hot places near the sea. It is also met with in western Asia, in some of the mountainous islands of the Medi- terranean, and on the slopes of the mountains of Atlas in northern Africa, where it appears to have been im- ported, probably by the Romans. But it has degene- rated in that part of the world : it is smaller in size, more brown in the colour, and the horns terminate in forks, instead of the numerous snags which they dis- play in colder countries. In these respects if approxi- mates the characters of the Indian deer ; and would lead one to conclude that, the stag is very general on the eastern continent, only in the course of years it has been much modified by difference of climate. We must not infer from the vast number of stag:s'- horns which are found in a fossil state, that there has been an equal number of stags ; for, as they come to their full head at five years old, each furnishes fifteen sets of horns, if it lives to complete its twentieth year ; and, therefore, making reasonable allowances for casu- alties, we may say that there are probably ten times as many sets of horns as there have been stags. D E Ji R. 253 R'lt still the numbers have not only been very con- siderable, but the stag, probably larger than at present, as already mentioned, must have been a very old in- habitant of jnany parts of Europe, and of these king- doms among others ; and he appears to have shared the fate of some other animals which have now perished as races, in certain catastrophes, the nature of which we do not, of course, very well understand ; but from which a portion of stags escaped, perhaps, on account of their fleetness. In the cave of Kirkdale in England, in some parts of France, and in Italy, the remains of the stag are found, blended in one ruin with the bones of the elephant, the rhinoceros, the hippopotamus, the hyaena, and the bear ; which is a demonstrative proof that the whole must have at one time been corn-habitants of the localities where their bones are found. Hence there arises the curious question, to what circumstances, chemical or otherwise, is it owing that the elephant, the rhinoceros, the hippopotamus, and the hyaena, have perished, while the bear and the stag have remained to the present time ? It will be foreign to our purpose to enter upon the formal discussion of this curious question, which be- longs fully as much to geology as to natural history ; and for the geological solution of which the data are but scanty. But we may remark in passing that these curious charnel houses, which carry our thoughts to times long gone by, are all, we believe, contained in fresh water deposits ; which abundantly shows that no ocean flood could have borne on its tide those animals which we now regard as foreign to the several locali- ties ; and as the elephant, the rhinoceros, and the hippopotamus are all semi-aquatic, found always low down — and as the hyirna is a burrowing animal, and neither it, nor any of the other three, is well fitted for flight ; while the stag is fleet, and the bear can climb, we can suppose that, these two animals could make their escape from a local flood, by which the others were borne to those entombments in which their bones are found. But what was the catastrophe ? — So far as we can judge, there has not been one but many; and they do not appear to have been attended by the action of any cause which disturbed the solid strata of the earth, any further than perhaps mechani- cal laceration of the surface; and, generally speaking, if we search upward along the rivers near which those deposits are accumulated, we might trace somethiu like the empty basin of what has once been a lake, which lake, by the bursting of its barrier, might have produced exactly the same kind of result with which we meet. — But we have to do with living animals, and not with the memorials of those that are dead. In Britain the stag, which was once so abundant, is now very rare ; and tlie few that are met with in Eng- gland arc objects of curiosity rather than any thin else ; and, though royalty still keeps up stag hounds, stag hunting even by these is a most ungallant and even ignoble sport, a sport from which the " merry men" of old would have turned away in mostbaronly indignation. The deer is carted to the field, hunted to a stand still, and then carried home again ; and thus ends the sport — equally unmeaning and unmanly. In former times it was far otherwise ; and nowhere is this most dashing of all exploits in the field described with more vigour or more truth of attention to the other animals incidentally mentioned, than in Scott's .beautiful national poem, " The Lady of the Lake.' We shall quote a few lines of the opening : — The state, at eve, had drank his fill. While danced the moon on Munan's rill, And deep his midnight lair had made, In lone Glenartncy's ha/el shade ; But, ere the sun his beacon red Had kindled on B< n-Voirhch's head, The deep-mouthed bloodhounds' heavy bray, Resounded up the rocky way, And faint, from farther distance borne, The echo of the hoof and horn. — Yelled on the view, the opening pack, Rock, glen, and cavern paid them back. To many a mingled sound at once The awaken'd mountain gave response . A hundred dogs bayed deep and stroug, Clattered a hundred steeds along ; Their peals the merry horns rung out, A hundred voices joined the shout; With whoop ! and hark ' and wild halloo ! No rest Ben -Voirlich's echoes knew. Far from the tumult iled the roe ; Close in her covert cower'd the doe ; The falcon from her cairn on high, Cast on the rout a wondering eye, Till, far beyond her piercing ken, The hurricane had swept the glen. Considered merely as poetry the passage which we have quoted is very beautiful ; but Scott had so keen an eye and so warm a heart to every scene and every production of nature, that it was only with him to glance at a subject, and it instantly became enve- loped in a flood of light. We have the habit of the stag quaffing the clear stream by moonlight. " The hart by water brooks ;" next we have him plunging into the forest for his nocturnal repose. Then at grey dawn we have the whole cavalcade of the hunters to horse ; and the bloodhound sent forward to find the slot, and track und start the deer. But for this part of the business we must refer to the article DOG. The hunt hurries forward after the staunch deer finder ; but not a hound gives tongue till the game is in view ; when the whole open like thunder ; and it is hurry scurry, and neck or nothing if the ground is in ;t state of nature. Nor is the character of the other two species of deer given with less truth ; the roe on the mountain top speeds off like the wind to those cliffs where no bloodhound could track him, nor pack run him down. On the other hand the doe, or female of the fallow-deer, a feeble and frightened creature, crouches down among the bushes, as if to escape by her insignificance from that fate from which her limbs are unable to bear her away. Last of all we have the falcon, perched securely on the rock, and equally safe in mountain castle, and her impetuous wing, looking down in utter astonishment, and contempt if you will, at all this coil and clatter among helpless and ignoble creatures, who must be content with walking and running on the humble earth, while she can cleave the air as swiftly as an arrow. In different parts of the world, as we have already mentioned, the stag varies in size as well as in colour, but its average height is about three feft and a half, and its general colour reddish brown above, and whitish beneath, with some black about the face, and a list of the same down the hind part of the neck and between the shoulders. The greatest known weight of a British stag is that of one which was killed in Aberdeenshire, namely, three hundred and eighteen pounds, exclusively of the entrails, head, and skin. It is alleged that, in Bavaria, the animal frequently exceeds this weight. In Siberia, and some parts of America, it is usually of very large dimensions ; whereas in China, Corsica, and some other parts of the world, diminutive varieties are found, which, in bulk, scarcely exceed a dog of ordinary size. Indi- viduals also occur of a very dark or blackish brown, some of a lighter yellowish brown, and some entirely white. The usual number of branches on the horns of a well-grown stag is six or seven, but some have more, and one variety is characterised by the superior amplitude of its horns. In most cases, the males only have horns ; and after their sixth year, when they arrive at maturity, they shed them annually in spring, when they seek the most retired places, and feed only during the night. The annual reproduction of these appendages constitutes, in many points of view, one of the most remarkable phenomena of animal physi- ology. First, it affords a most striking proof of the power of the nutritive senses, and the natural growth which depends on it in warm-blooded animals, since the horn of a stag, which may weigh twenty-five pounds, is completely formed in ten weeks •, secondly, it exhibits a singular instance of a limited duration of life in a part of the system, entirely independent of the life of the whole ; and thirdly, it manifests a change of calibre in particular vessels ; for the branches of the external carotids, which supply the horn with nourishmeut, are remarkably dilated during its growth, and recover their former area when that process has ceased ; fourthly, it bespeaks a peculiar sympathy between the growth of the horns and the generative functions ; because castration, or any essential injury of the organs of generation, impedes the increase, alters the form, and interrupts the renewal of the horns. There are certain technical names given to the stag, according to his age, which are worthy of being noticed. The young, whether male or female, is styled a calf, and for a few months there is very little distinction between the sexes. At the age of six months, the bassets, or rudimental horns, begin to appear in the male, but they do not advance farther that year than two cylindrical knobs. In the second year they are longer and pointed, in which state they are spikes or dags, and the wearer of them is called a brocket. In the third year the horns put out two or three tynes or branches, and the deer becomes a Kpayad. The crown, or surroyal, appears on' the top of the beam the fourth year, and tnen he is a staggard. The fifth year he becomes a stag, which is the only year that he technically retains the name of a species ; for the sixth year he becomes a hart, and so remains for the rest of his life. In the sixth year he is called a hart of ten, when he is? considered still too young for being legitimate game ; but after his seventh year he is said to be crocked, or palmed, or crowned; after which he is fair game. The number of snags or tynes in the crown of the horn seems to depend a good deal on the richness of the pasture, and on their having proper shelter and food during the winter. In former times, specimens were found, both in England and in other countries, with more than thirty snags on the crown of each horn ; but we believe that half that number is of comparatively rare occurrence. The female passes through a succession of stages as well as the male, but they are not so important ; and, besides, regular sportsmen never make game of the females. The female of the first year is a calf, of the second year, a brocket's sister ; and the third, and ever after, a hind. Stags do not mew or shed their horns immediately after pairing, though there is reason to believe that the decay of the horn begins at that period. The crowned harts are the first to shed theirs, arid always the older the earlier. Something depends upon the season and the pasture, but the average time may be reckoned about the end of February. The harts often shed theirs a month or six weeks later, and the younger ones a month or six weeks later still. The technical word for the horns is attire ; and when these are shed, the animal is said to " lose his attire." In this state he is comparatively defenceless, and retires into the shadiest parts of the cover, or into the most remote or unfrequented parts of the pasture, where there is no cover. He remains there during the summer, and about the month of August the horns are completed ; and he clears them of the skin of velvet with which they were covered, by rubbing them against trees or rocks, or against the ground The hind is in retirement in a different part of the pasture during the same time, where she attends to her calf with truly maternal solicitude, and shows considerable address in drawing off any apparent danger from the place where it is concealed. The young of the former year and the brockets form a third association, but they also retire when they shed their horns. In the rutting season the harts fight desperately with each other, but it is only when two of the same age come into contact with each other that this occurs, for the weaker always gives place ; and indeed there seems to be a provision of nature to prevent these rencontres, for the fury of the rutting season comes upon them in the order of seniority, which is also the order of strength. In their battles their horns often get so entangled, that the two are thereby held together till both perish. The great agitation into which they are thrown at this period completely exhausts them, which is not to be won- dered at, when we consider that they abstain almost entirely from food, and run about the pastures " routing" or roaring, as if they were mad. Imme- diately when the stimulus is over, they withdraw in a state of great exhaustion, and remain quiet, eating a great deal, especially acorns, if they can find them ; and this is the reason, probably, why they attain a larger size in oak forests than in forests of pine, or on the open hill ; and it may in part account for their superior size in former times both in Britain and on the continent. In England, those noble animals are, as we have already hinted, comparatively few ; but the case is different in the mountainous parts of Scotland, especially in the central Grampians, be- tween Athol on the south, and Badenoch and Strathspey. There are a few in the south-western Grampians, and also in the mountains northward of Lochness ; but there is nothing which can be con- sidered as a deer-forest in either of those places, or anywhere in Scotland, or, we may add, in Britain, except the forest of Athol, or, more strictly speaking, the forest of Minigag. The eastern part of that forest contains some of the loftiest mountains in Scotland, and it gives rise to various branches of the rivers Dee and Don towards the eastern side, of the Spey towards the north, and of the Tay, more especially the Bruar and the Tilt, towards the south. There are extensive natural forests of pine in the upper glens or valleys of the eastern rivers, but the deer are not quite so abundant there as they are in the south, where the exposure is warmer and the pasture better. Glen Tilt and Glen Bruar, espe- cially the former, are the principal winterings ; but DEER. 2.07 the deer, if all together, have a range of not much leys tliun 100,000 acres of hill, and on this there are certainly nor. fewer altogether than 7000 or 8000 ht-ad, ofd and young, the greater part of which are the property of the Duke of Athol ; and the great hunts, or rather slaughters, most frequently take place in Glen Tilt, though the more laborious opera- tion of "deer-stalking" is pursued in other places. On the great hunts, they are driven by a circuit of people, who bring them to a pass or narrow, whore the marksmen are posted, so that they can select and make sure of their victims. This is not a very manly sport, but it is very efficient " pot" hunting ; and the nature of the ground renders it impossible to adopt any more sportsman-like mode. It is understood that, from the care bestowed upon them by all the proprietors, red deer are becoming more numerous on those mountains ; and though the hill is quite open, and the keepers are but few, there is comparatively little poaching ; and, indeed, it is rendered unnecessary, because the deer are always straying so far out upon the spurs of the hills, that any one who is so inclined may occasionally have a shot ; and to attempt shooting deer on the open Grampians, as a matter of profit, is nearly out of the ; question. When poaching is attempted, it is generally in the winter, or in the latter part of the autumn, which usually has all the horrors of a very severe winter in those exposed and upland places ; and there have been in--tani'< -s in which adventurers, who went to spend the night on the hill for the purpose of Staining deer illegally, have had the most terrible justice executed upon them by the storm. The snow storms on those mountains nearly rival in violence the " temporales" of the Andes : the snow makes the air as dark as midnight ; and the wind drives with the voice of thunder among the crags, and sweeps the waste with the force of hurricanes, so that men are rolled before it like chart, hurled over some pre- cipice, and lost, — until the crow and the raren point out the place of their bones in the ensuing summer ; tor the snow in which they are buried in great part preserves their bodies to become food for these dark and dusky-coated scavengers of the desert. Such is the situation and character of the most extensive forest of red-deer which now occurs in this country. In England there are remains in some of the royal forests, and perhaps in a few other places, but they are comparatively few, and do not stamp the principal character upon the locality as they do on thr> Grampians. FALLOW-DEER (Cervus dama). This species is smaller, feebler, and more tame and common-place in all its characters than the stag. There are no canine teeth in either sex. The male only has horns, which are round in their section, with two pointed antlers, and the summit ; almated lengthways. The colours are variable, but they are in general brown, dappled with white. The horns of the male fallow-deer, or buck, are divergent, terminated above by a flattened longi- tudinal palm, toothed with what are termed advancers ; trie base of the beam round, with basal and median, or brow and bezantlers, pointing forward. It has no canine teeth, and the nose is terminated by a muzzle. In size it is inferior to the common stag. In summer both sexes have the back, flanks, and thighs, of a fulvous-brown colour, diversified with numerous white •pots. In winter these parts are wholly brown ; the NAT. HIST. — VOL. II. buttocks are always white, with a black streak on each side ; the tail is longer than in the stag, reaching to the houghs, black above, and white below ; a dark line passes along the back ; the belly, inside of the limbs, and under the throat, white ; the head, neck, and outside of the legs, reddish grey. ! allow The male of the fallow-deer is usually called a buck, the female a doe, and the young a fawn. The buck fawn has no appearance of horns the first year, but they come up in simple snags the second, at which time it is a pricket. The third year there are two branches, and the palm begins to be formed on the top of the beam ; but it is not properly formed till the fifth year, when the animal becomes a buck of the first head, which answers to the stag of the former species. The horns have now attained their prin- cipal shape, except on the margins of the beam, where they every year acquire additional snags, which are called spillers, or advancers, but they con- tinue to increase in size. As is the case with the stag, they drop their horns in the spring, and both that operation and the rutting conies on about two weeks later. The period of gestation in the doe is eight months ; she becomes fertile the second year, and ceases to be so about the fifteenth. The fawns, at a dropping, are one, two, or three, according to circumstances. Fallow deer are gregarious ; but the bucks live apart except during the rutting time, and in winter, when most gregarious animals live indiscriminately. Where the herd is large, it is, however, generally divided into packs, each under the guidance of the oldest or most powerful buck. This species is so well, known as the common park deer of Britain, that a minute description of it is not necessary. It is not known, and probably never was known in a totally wild state in this country ; and this in part accounts for the diversity of colour we meet with. In the south of Europe it grows to a much larger size than with us ; and hence it has been supposed that it is native there ; but the point is not fully ascertained, and it may be an importation from the west of At;ia. In the central countries of Europe, wild ones are fevf, and there are none to the northward of the Carpa- thian mountains. But in all parts of Europe, where there are extensive parks, there are fallow deer in a R DEE I*. state of semi-domestication ; and where there is cover in the neighbourhood, they often escape in such numbers as to become an annoyance to the farmers. The flesh of the fallow deer is understood to be more delicate and juicy than that of either of the wild sorts in this country ; and it is in consequence in high request as a luxury. The animals them- selves, though destitute pf the grandeur of the stag and the gracefulness of the roebiujjf, are very orna- mental in parks ; and where undisturbed, they are very tame and gentle throughout the greater part of the year, and not nearly so formidable in the rutting season as stags. The sound of their voice is low as compared with that of the others, an4 it gets the technical name of groaning. Bucks when b,unted do not take the country in breadth as the stags do, but run in circles, and very frequently take the water, though they are not such bold swimmers as the stag. The chase of them, both from the grounds they fre- quent and from their own characters, is not so strik- ingly effective as that of the stag, but it requires more care, as they are apt to throw out the hounds and leave them at fault. Though the existing fallow deer appears to be a native of the south, at least of the south of Europe, though certainly not of tropical countries, yet the large deer, of which the remains are found in the fresh water deposits, are usually referred to this species, or at least to one resembling it, on account chiefly of the form of the horns ; and it is a little puzzling that the fallow deer which appears to have a more southerly habitation than the stag, should have pal- mated horns, approaching more nearly to the charac- ter of those of the polar deer than those of the stag do ; but, as is the cuse with all animals which have been very long in a state of total or partial domestication, and which accompanied men in their migrations from country to country, it is by no means easy to ascer- tain whether the fallow deer has degenerated in size from the fossil specimens, or whether its horns may not have altered their character from being simply forked as most of those of the deer in warm coun- tries are, to that palmated form of the upper parts of the beams which they now display. The ROEBUCK (Cervus caprcolus). This is the most light and handsome of all our deer ; and in some respects it approaches the antelopes, the ancients giving it and some of the species of that genus indis- criminately the name of Dorcas, that is " bright eye ; " no lachrymal sinuses, scarcely any tail, the colour a greyish yellow, varying more to reddish or brownish, but always with a large white disc on the buttocks. The horns are rather small and cylindrical, with a small antler on the middle of the beam pointing for- ward, and a second one higher up and turned to the rear. The roebuck is pretty generally distributed, being found in all the temperate parts or Europe and Asia, and even it is said in India, though there it has been confounded with some of the Indian species which resemble it a good deal in the forms of their horns. This is the smallest species in Europe, not exceeding four feet in length, and standing about two feet high at the shoulders. There are coloured varieties, one very red, and another yellowish brown, yad a third nearly black ; but they all have the cha- racteristic white disc, at least in the winter, and the luil is never more than an inch in length. Their sum- mer and winter clothing differ a little both in colour and in texture. In winter the fur is completely soft and tinged with grey on the neck and head, and the disc is much less conspicuous ; but in winter the hair thickens and hardens, and the colour deepens, espe- cially on the upper part. The manners of the roebuck are different from those of the species hitherto described. They are not gregarious, and therefore do not make the same appearance in proportion to their number as the deer. The male is also monoganous, and remains attached to one female for life, the two keeping company, or at least being near to each other all the year round, and the rutting season not being accompanied with that violent excitement which takes place in the others, more especially in the stag. The period of gestation is also different, and so is the time of shedding the horns in the male. Rutting time is in the beginning of November, and the female goes little more than five months, while the fallow deer goes eight months, and the hind a little more. The pairing is thus about two months later than in the others, and the fawns are dropped about two weeks earlier. The male also sheds his horns soon after the rutting time, and acquires the new ones during the winter, so that he is in his apparel for a much longer period of the year than either the hart or the fallow buck. The doe drops two fawns, for which purpose she retires into the closest cover that she can obtain, but at the end of about two weeks she makes her appear- ance with them in company ; but she hides them if danger appears, and shows considerable address in enticing enemies away from the place of their con- cealment. They are generally, if not invariably, a male and female, which continue with their parents during the summer ; but previous to the rutting time they are driven off' to shift for themselves, and to keep company with each other for life, which is from about twelve to fifteen years, if no casualties occur ; but as roebucks prefer the open hill to the shelter of the forest, many of them perish in severe winters. They are much more destructive to young planta- tions than either the stag or the fallow deer, as they prefer the tender twigs and buds of these to grass ; but they are lively and vigorous creatures ; and few sights are finer than that of a roebuck bounding among bushes, or up a hill side among tall heather. This plant is often as tall as himself, so that when he alights he is concealed, but at every bound he rises to some height clear of it, and puts one in mind of what is stated pf the antelopes in the coppices of Southern Africa. The roebuck leaves a strong scent ; and therefore he is more easily found than the stag, where stags are not numerous ; but he is not more easily caught. As the stag runs out, he is sure to fatigue himself ; and though he recovers if he can reach the water, and makes a formidable resistance when he stands at bay, yet, if the dogs are staunch, and the ground practicable, he is almost sure to be taken ; the roebuck on the other hand shows artifice : he dashes off at first, but if pursued he doubles, bounds sideways to some cover with immense leaps, and With the velocity of a bird, and couches down till the chase pass him, and then, bounding from his cover, he is off in another direction. The same roebuck has been known to be hunted through several counties ; and of these one is mentioned by the late Mr. Bewick of Newcastle. It had been hunted out of Scotland through Cumberland and various parts of the north of England, and at last took shelter in the copses on DEER. tiifi Tync ; there it was frequently seen, and as fre- quently hunted. But no clogs could come up with it in speed ; and its arts were equal to its agility, as it swam the river, or in some other way escaped. The chasing was continued during1 the sojourn of a very severe winter ; and upon one occasion it crossed on the ice, and by so doing was so much strained, that it was easily taken alive. After being kept for some weeks in the house it was again turned loose, but all its enterprise and all its cunning appeared to have left it ; for after being chased only a little way it lay down in the middle of a brook, and was killed by the dogs. This anecdote shows that the peculiarly elastic cha- racter of the roebuck is quite incompatible with do- mestication. It is also very difficult to confine this species within enclosures, in consequence of the height to which it can leap ; and as its flesh is not consi- sidered quite so good as that of the others, and far- ther, as there is not so much of it, it is left in a great measure to its native freedom on the hills. It should seem that the roebuck by being less excited in the rutting season than the others does not come into such high condition preparatory to that season. In England, roebucks are now very rare ; and as there is cover for them in most of the places where they might be looked for, they are not easily found. In the Scottish mountains, however, they are more abundant, though scattered, and rarely seen more than one at a place at the same time. They are not met with in exactly the same places as the red deer, but rather where there is an admixture of hill and rock and copse. They are also, at certain seasons of the year, met with further down than the red deer generally are, but they do not hesitate to take an occasional dash into the inhabited parts of the country when the winter is very severe on the hills ; but on these occasions they generally have all their arts about them ; so that it is but a passing sight which one can obtain. It is also more difficult to get a shot at a roebuck than at a red deer. In Scotland they are found as far north as Sutherland and Caithness ; but their chief haunts are in the neighbourhood of those places which have been described as abounding most with red deer ; only from the peculiarity of their manners, and the fact of their feeding in the copse and on the twigs, rather than browsing the herbage, they are not often seen, to which their habit of lying close till the danger be passed, contributes still farther. There is no account of the horns of the roebuck being met with in the same accumulations as those of the other deer in this country ; but they have been found in some parts of France, though it is said that there are some peculiarities in the fossil remains which are not found in the living animals ; and thus, though there is a similarity established, there is not a perfect identity, so as to warrant us to conclude that the roe- buck of our times existed and inhabited at the same period and in the same country with those now ex- tinct animals the Paleot/ierium and the Mastodon, whose remains are found in the same accumulation of peat, near the river Somme in France. Such is a short account of the three species of deer which are met with in the wilds or in the parks of our own country ; and they are the ones whose manners we have the best access to study. THE AHU, or Tartarian roebuck— Cervus pyg argus. This is the roebuck of the middle latitudes ot Asia, and of part also of the east of Europe. It is a larger animal than our roebuck, and differs from it in having th« hair longer, and the horns more developed, &nrt more furrowed and tuberculated in their basal parts. It is very generally distributed over the margins of the waste, from the mountains which divide Persia from the central countries of Asia, to some distance into Siberia ; but it is not found in those parts of that extensive region which have a decidedly polar climate. In the summer season it keeps to the moun- tains, among the cliff's of which it bounds with great vigour ; but in the winter it descends to the plains. Like the roebuck it has no lachrymal sinuses, and the tail is still more deficient, being nothing more than a mere tubercle. The colour on the back is brown in summer, and that on the under part is yellowish. On the hinder part of the thighs and around the rudi- mental tail, there is a disc of white, larger and more conspicuous than in that of the roebuck ; and this mark is constant amid all the varieties of colour in the individuals, and all the changes from age or cli- mate ; and the old and young, and also the summer and winter appearances are so different, that animals in these states have been described as distinct species. A space round the nose and sides of the under lip is black, but the lips themselves are white ; and those characters also remain constant. The hair of this species is exceedingly thick, more so, perhaps, than that of any other. In summer it is stiff and erect, allowing the air to reach the skin, notwithstanding the great thickness of the covering. In winter it gets shaggy, and falls more closely on the body, forming a very warm covering. It does not appear that at this season it gets any of that long in- termixture in its coat to which the name of " snow hair" may be applied without much impropriety ; but its general coat becomes dry and bleached to a hoary colour at the points, which answers nearly the same purpose. In all the field animals of central Asia, from the Himalaya northward, there is some provision of this kind ; and the great change of seasons to which this part of the world is subject, is at once the necessity and in all probability the cause of this provision. In summer, the heat is excessive ; and the plains are completely burnt up, so as to wear the aspect of vast floors of indurated clay ; and at that season there is no rain except on the mountains : and as the last plants upon the margin of the desert, or in that kind of shelter which makes an incipient desert of the whole country, are always of a saline nature, the ground is covered with saline incrustations. It is at this season that such animals betake themselves to the mountains, while the wandering horde of Tartars with their cattle, move farther to the north, and reach the lower parts of the plains or steppes, where there is still some moisture to be found. In winter the cold is as proportionably severe as are heat is ardent in summer ; for in plains the elevation of which is not great, and which lie on the same parallel of latitude with the south of Italy, and the centre of Spain, where snow is rarely seen upon the plains, and where there is very seldom ice upon even the shallow pools, the rivers are so completely frozen over, as to afford pontage to the inhabitants. So great a difference between the summer and the winter naturally produces a corresponding difference in those animals which, like the aim, are freely ex- posed to the weather all the year round ; and this climatal difference is quite sufficient to account for a.t the external differences which are traceable between Ra 200 DEER. this roebuck of central Asia, and the roebuck of Europe. As we are not very intimately informed on the subject of the natural history of this part of the world, it has not been ascertained with certainty that the manners of the animal under notice corre- spond exactly with those of the roebuck of the west ; but the structural resemblance, we may almost say identity, is so great as to leave little doubt upon the point. It is probable that this animal is found over the greater part of the high lands in Asia, and that it is modified in its coat in different parts there to as great an extent as the difference between it, as de- scribed in the south of Siberia, and our roebuck ; and what gives more probability to the supposition of its being but one species from India to Britain, is the fact that in the milder climate of India, there is nearly the same deviation from the Tartarian type as in the milder climate of Europe. Our roebuck is smaller than the Tartarian, shorter and smoother in its coat, and with the horns less developed. The Indian variety is described as being still smaller than ours, more smooth in its coat, and with the horns less deve- loped. These circumstances would lead us to infer that the roebuck is more generally distributed over the eastern continent than any other of the larger mammalia which remain in a state of nature. There is still, however, a good deal to be done in order to trace the connexion between the different localities in which it is found, and to mark the gradation by which the characters of the one locality run into those of the other. But these points are not impossible, for they only require observation ; and as it is highly probable that lines of communication may soon be opened up through central Asia, we shall not much longer remain in such deep ignorance as we are at present respecting that portion of the country which may be saiu to connect the four distinct characters of land and climate of which Asia is composed. Siberia sloping toward the northern sea, China to the eastern, India and Persia to the southern, and the central coun- tries of Asia toward the great salt-lake of the Caspian. All these four are very different in their different characters, and in their vegetable productions ; and therefore they must produce corresponding modifica- tions in the characters of animals ; and if we could once see clearly how one species, such as the roebuck, common to the whole, has been modified by each, we should be furnished with a key to much of their natu- ral history, the knowledge of which we never can obtain by local and individual observation, however assiduous and however accurate. Nor would the in- formation be confined to the present time only ; for as it is well ascertained that the roebuck has inhabited even the west of Europe along with some of the lost animals, and as the fossil horns resemble those of the Asiatic more than the modern roebuck of Europe, this species, well made out, would be at least one means of carrying our knowledge backward to the time when they existed. The NEPAL STAG — Cervus WUlichii. This species is found in the upper valleys of the Himalaya, and partakes partly of the characters of the common stag, and partly of those of the roebuck ; but more of the former. The horns are circular in their section, each is furnished with two brow antlers turning upwards,which with an additional snag higher up the beam, form a sort of bifurcation. The beam rises with a contrary flexure, bent backwards, and then slightly forwards. Tn»J size of the full-grown animal is large ; the colour on the upper part yellowish brown ; lachrymal sinuses large; the ear short and broad, the tail very short, sur- rounded with a very large white disk. The legs fawn colour, the hoofs black, very fine in their texture, and sharp pointed, resembling those of the mountain an- telopes. The history of this species, its habits, the change of its colour, and the texture of its fur with age or with seasons are, however, very imperfectly known. Its most remarkable external character is the position of the disc, which is more above the tail than below it, whereas the contrary is the case in most of the other species. *In the south of Asia and the Asiatic isles, there are two distinct groups of the genus Cervus, which differ in some respects from the deer of Europe, and the different members, whether we are to consider them as species or as varieties, which compose each group, have certain characters in common which enable us to generalise and thereby shorten, at least, a part of the descriptions of them. As these are known only in Asia, at least, as native animals (for some have been imported into Europe in the living state), we can describe them only by their names as known to natu- ralists. The one group is styled Rusa and the other Ax'is, which we shall shortly notice in succession. ROSA. The general characters of this group are : the horns round, with a brow antler and a single snag near the tip, but without any bas-antler or branch on the middle; they have a broad muzzle, and large lachrymal sinuses. The males have canine teeth, and rugged manes ; the tail is also longer than in any of the European deer ; and some of them at least are of larger size. They are the upland or woodland deer of India, and the larger islands of the East ; and in their manners they in general more resemble the stag than any other of our species of deer. There are several species of them named in the books ; but some of them are known only as museum specimens. It is certain, however, that the animals are very plentiful in the tangled and unfrequented parts both of India and of the islands. Indeed, it is probable that some of the species may inhabit the southern side of the mountains considerably to the westward ; for one is mentioned by Aristotle, of the size of a stag, and with a mane on the withers, and a horn resembling the roebucks. The GREAT RUSA — Ccrvus hippelaphus. This is one of the species the habitat of whieJi is not very well known, though it is probable that it exists in many parts of continental India ; but the specimens which have appeared in Europe have been obtained from the islands, chiefly from Java. The hair is coarse and hard ; and, after the first year, that on the throat, cheeks, and neck, is long and shaggy, the latter form- ing an erectible mane. In summer the colour is yel- lowish, and the disc on the buttocks nearly obliterated, but in winter the colour on the upper part becomes gray-brown, and the disc becomes more conspicuous. Different specimens have, however, varied so much in their colours, as well as their size, that the species is not very well made out. The SAMVER OF BENGAL— Cervus Aristotelis. This species is much better known than the former, being met with in many parts of India, especially in the val- ley of the Ganges. Its characteristic distinction taken from the horns, is that of having the branch or second antler very far up upon the beam, and turned to the rear, instead of forming a fork with the tip of the beam, as in most others of the group. .IDJKIIv DEER. 261 The burr of the horn is very broad and pearled ; the first antler is cylinder-shaped, strong and straight, and stands nearly vertically upon it, measuring about ten inches in length ; the beam bends from the back of it obliquely outwards, arid to the rear, and with a sweep turns its point backwards ; near the summit, or at more Th;in two-thirds oi' its length, is the second posterior and internal branch, short and pointing upwards. In the British Museum there is a specimen measuring about twenty-three inches, which is very rugous and robust. The horns stand upon a broad und short pedicle ; the lace is straight, the nose pointed, the muzzle sunill, and the suborbital opening is very considerable. The ears are broad, with white hairs standing up around the orifice; the tail is black, reach- ing half way down the ham, and is well furnished with hair. The throat and neck are covered with long coarse dark brown-grey hair, reaching partially over the shoulders, susceptible of being raised like a lion's mane, when the animal is excited. The shoulders, head, back, rump, and buttocks, are dark-brown in summer, and almost black in winter ; outside of the ears sepia ; the belly whitish, as also a ring round the nostrils and mouth, separated from the brown by a deeper shade, which spreads up the face ; the inside of the limbs and legs fawn colour, darker over the knees down the front; the breast is black. The male is nearlv the size of the elk, and indeed is so named in India by the Britisli sportsmen. They represent him as being excessively strong and vicious. Some of them, on a shooting expedition, had crossed an arm of the Jumna to a woody island in quest of game ; — they were on the back of an elephant, and entering the jungle suddenly roused an old male of this species. On seeing the elephant he started up with a long shrill pipe or whistle, which caused others to rise and dart into cover, while he stood at bay with his bristly mane on end, in a most threatening attitude : but before the sportsmen could prepare proper shot, he wheeled round and dashed through the underwood with the facility of a rhinoceros. Captain Williamson evidently met the same species. He describes the stag as arriv- ing at the size of a Lincolnshire cart-horse, fifteen or sixteen hands high, shining black, with tanned points (of the hair r1) One of these, he says, heads a score of females, who are of a mouse colour. He likewise calls it an elk, and adds, that they reside in the Prauss jungles. But though this species gets the name of the elk, there is no resemblance between them, farther than the generic character. This is decidedly a spe- cies of the warmer climates ; and though we are but little acquainted with its habits in wild nature, it doe: not appear to be so social as the elk ; indeed, the deer of warm countries do not in general appear to congre- gate in such numbers as those of temperate and polar climates. MALAY RUSA — Ccrvus equmus. This is also a large species ; and though the specimens hitherto brought to Europe have been obtained from the Suuda Islands there is every reason to believe that it inhabits the Malay Peninsula, and probably also some parts o India. When full grown, it is described as being o the size of a horse, with the horns tapering, and the second snag, which is turned to the rear, very small The horns are of a very bright reddish brown ; botl sexes have canine teeth ; and the frontal bone is mud flatter than in most species of deer. The colour is grevish brown, paler on the under part ; rust colon on the haunches, and the tail ; the insides of the legs vhitish, the muzzle black, arid the chin white. The bllowing is Hamilton Smith's description of a speci- men exhibited some years ago at Exeter Change. — ' The animal was then about two years old, and his rorns were simple, or in the brocket state ; the next year its new horns showed the bifurcation of the surn- nit, to be as in the Black Rusa of Bengal ; that is near the summit on the internal posterior side. It was hen four feet, or something more, at the shoulder; and still higher at the croup ; its eyes were large, dark, and mild : the suborbital slit opened at pleasure, and was remarkably expanded when it drank, with a per- ceptible action of the air passing in and out as before noticed. The ears, broad and pointed, were nearly naked within, and whitish-grey without, the face, shoul- ders, back, and thighs were of a dark brown-grey ; the nair rough and bristly on the neck and throat. This colour was darker, and the hair very long, especially the second year, when the crest or mane on the neck and throat hung very heavy and thick ; the breast and belly were of a dark ash, almost black. A consider- able disk of a clear rusty, or orange, colour, expanded over the buttocks, lined the inferior side of the tail, and was separated by a black line from the grey of the thighs. The tail, about a foot in length, was black above ; the joints of the legs, the inside of the thighs, and their anterior side were yellowish dun, and the legs from the joints downwards buff; the chin was white, with a black spot at the corner of the mouth, on the lower lip, and a bar of the same colour above the nostrils, which were placed on a black muzzle ; the cheeks and space round the eyes were buff, pass- ing to grey." The horns are of a dark colour, rugous, robust, but shorter and less curved than in the Hippelaphus ; the anterior antler, and posterior snag, are both short and obtuse, but from the size of the first, or brocket horns, of the animal being near eight inches long, it is pre- sumed that they become, it not much prolonged, at least very bulky : his second horns were about four- teen inches. This species resembles the Bengal Rusa in many particulars : both have the forehead flat, and the face straight ; the muzzle small, with spots of black on the under lip, and a ring round the nose ; the ears naked inside ; the horns short, stout, and similarly formed ; the same mane and dark breast. In fact, the only obvious differences are the presence of a disk on the buttocks of the present, which does not appear on the former, and that of dimensions ; but even in this particular there can be no great disparity. It may be, therefore, that ultimately these two will be marked as only varieties of one species. There are some other species or varieties described as inhabiting the Malay peninsula, or the adjacent isles ; but it is by no means unlikely that some of them are the females of the species now described : and, indeed, there is some reason to suspect that all the Rusas are merely climatal varieties of one very widely distributed species, which may be called the stag of South-Eastern Asia, or the Indian stag ; we shall, however, mention two others, which differ con- siderably from those which have been enumerated, and which are the most remote from continental Asia in their localities. The MAUIANA RUSA — Cervus Manama. This species inhabits the group of the Mariana or Ladrone islands, which lie between twelve and twenty degrees north latitude, and a hundred and forty-four and a hundred and forty-eight east longitude. There is every 262 DE reason to believe that it is not originally a native of those islands, but has been imported from the conti- nent of Asia, probably from China. A specimen was brought to Paris, by Quoy and Gainard, in Freycinet's voyage of discovery, of which the following is a de- scription : — " It is more robust, but not much taller than the roebuck, with round divergent horns standing on a low pedicle, having two antlers, the basal nearly vertical, and at its junction with the beam a small process, not unlike a trilobed tooth ; the other is pos- terior and internal, and compared with the size of the head, the horns are large and heavy, being about thir- teen inches long ; their colour is ashy, and they are extremely rugged. Between the horns the skull has a longitudinal eminence, and before the orbits, near the base of the nose, are two longitudinal convexities, very remarkable, and the species is destitute of canines, by which character it approaches to the true axis ; the face is almost black, with a streak running down from the horns, between the eyes, to the nose ; the muzzle small and black, and the colour of the whole body dark brown, slightly mixed with grey, at least such are the colours now discernible, the specimen being in a bad state of preservation ; the tail is about four inches long, and black. A fawn brought from the same island in the above museum is fulvous-brown, without spots ; the throat is whitish ; a white spot at the end of the lower jaw, and one at the base of the ear. The inside and anterior border of the thighs and buttocks are white, and the legs buff." This species, like most of those of the islands, is described as being very tame and gentle in its manners, which gives additional ground for supposing that it is not an aboriginal animal, but has been carried to the islands from con- tinental Asia. Rus A OF TIMOR — Cervus Peronii. Only the head, we believe, of this species has been brought to Europe ; and from the little acquaintance that we have of the interior of the island of Timor, nothing is known of its habits in its native country. It is understood to be smaller than any of the rest of the group, dark coloured, with slender horns, and the second snag forming a more regular fork with the tip than in the other species of the group. This is the most southerly inhabiting deer in all the eastern continent or its islands ; for the next land which we meet with to the south of Timor is New Holland, in which there are no deer, except such as may have been very recently imported by the colonists. Axis. The animals of this group stand nearly in the same relation to the fallow-deer of Europe, as the rusas do to the stag. They are smaller in size, and less vigorous in structure ; they have no canine teeth, and their skins are, generally speaking, dappled with white spots. Generally speaking, they inhabit lower down than the deer formerly described. The SPOTTED Axis — Cervus Axis. The chief dis- tinction between this species and our fallow-deer is in the form of the horns, which are round in their section through and without any palm. The horns stand nearly vertical, only with a slight bend forward, and the points inclined towards each other. They have a basal antler pointed forwards, and another on the middle of the beam turned backwards ; the muzzle is black, and there are no lachrymal sinuses. There is, indeed, so much resemblance between this species and fallow-deer that when their horns are shed, it is dif- ficult to distinguish the one from the other. The chief marking colour is in the dorsal, line, and the disk on E R. the buttocks. The dorsal lino in the axis is very deep-brown, and marked with white spots, while that on the fallow-deer is paler, and has the spots only on the margin. The disk in the fallow-deer is white, that on the axis is yellowish. The two sexes are also more equal in size than the fallow-deer, the female being larger than the doe, and the male not larger than the buck. There are, however, considerable varieties both in size and in colour. Axis Deer. These deer are very plentiful in the lower districts of India, where they inhabit the margins of the jun- gles ; they are known by the general name of hog- deer, and are much prized by the sportsmen of the east. We believe they are seldom met with in the countries above the Ghauts, or passes of the moun- tains, as the large deer are seldom met with below ; and, indeed, in all their characters, and in all their habits, they correspond so much with fallow-deer that, notwithstanding the different form of the horns, it is difficult to refrain from considering them as the same species ; and, perhaps, as the parent stock which has supplied the fallow-deer to the western world. Several varieties have been described, but they appear more accidental than otherwise, so that it is unnecessary to mention them particularly. There is still another group of deer, belonging to the south-east of Asia and the Oriental Islands, which have very peculiar characters, and which are decidedly distinct from any of the rest. Their most remarkable characters are, that the males have the horns upon peduncles, which can be traced upon prominent ridges down the forehead almost to the nose and canine teeth in the upper jaw, which are so long that they protrude beyond the lips. They have also very deep lachrymal sinuses. The tongue is very long, and they can "protrude it upwards as far as the eyelids. They appear to be intermediate between the deer, properly so called, and the musks ; and it is doubtful whether they shed their horns seasonally like the other deer. They have been brought chiefly from the Sunda and Philippine islands ; but there is also a species in Nepal. There is some difficulty about the different species, but there seems no doubt that several of them are distinct, and those which are obtained from the Philippine islands, from the Sunda DEER. 2(>3 islands, and from Nepal, are all different from each other. They are elegantly formed creatures, am!, notwithstanding their produced canine teeth, they have a very mild and gentle aspect. The following is the description of the Sumatra species or variety : — The body is compact ; the legs remarkably fine and slender ; the muzzle is rather broad ; and the canines assume the form of inverted tusks, sharp at their points, turned towards the animal, and outwards. Two rib-like eminences ascend from above the nose over the eyes, and, elevating themselves from the head, in the form of slender pedestals, to the height of two and a half inches, terminate in a flattened summit. Upon these the horns are placed, about three or four inches long, forked at top, with the Eoints turned inwards, and with a small branch at the ase pointing forwards ; between the ribs the skin of the face is doubled into a fold, which has the appear- ance of a third or central rib ; the fur is fine and dose, of a greyish brown, paler beneath ; the breast, inside and anterior face of the thighs, are whitish ; the tail is short, dark above and white below. The Malay name of this animal is Kijang, or Muntjak, the "latter of which has been adopted as the specific distinction. They are understood to live in pairs, in the same manner as the roebuck. Several varieties of them have been imported from Sumatra, from the Philippines, and from other parts of the Indian Archipelago, the history of which is not very clearly made out: but the following is the description of one from the Philippine islands : — " The peduncles and the horns are about one-fourth the length of the head, and thicker than those of the kijang, and the ridges which terminate in them extend down only as far as the eyes. The rest of the face is flat, with the forehead slightly arched ; there is a dark streak on the anterior base of the pedicles, and between them the hair is black, forming a spot with the point downwards, and leaves a crescent of a dirty buff between them ; this colour spreads round the orbits and on the cheeks ; the lachrymal sinus is dark ; the ear> rather short and obtuse, whitish within, dull buff outside ; the colour of the coat is wholly brown sepia- grey, clearer on the throat, and darkest on the neck and eyes ; the tail is three inches long, black above and white beneath." There are several museum specimens from the Oriental Islands, which appear to differ from each other ; but as some of them are only fragments, their characters are not fully made out. There is one, however, of which a pretty distinct account is given : — THE NEPAL MUNTJAK, or Musk-deer of Nepal — Cervus moschatus. In the Oriental Collections for January, &c. 1798, vol. ii., Sir William Ousley figures an animal, under the name of Musk-deer of Nepal, from a drawing executed by a native artist, with the following dimensions, communicated by Colonel Iron- side : — Length, from between the ears to tail, two feet four inches ; height, two feet ; length of head, seven inches ; of the tail, six inches and three quarters ; of the tusks, two inches and one-eighth ; the hair bristly and thick, two inches long. By the illuminated plate, the animal must be entirely dull fawn colour, with the superior part of the tail alone dark ; the horns, placed upon high pedicles, are dark, simple, without branches, and pointing to the rear ; the limbs are very slender ; the spurious hoofs small ; tno neck rather short. The habitat and character of tne hair render it probable that it is a distinct species ; and although no reason is assigned ibr the name of musk-deer, that being the designation of the natives, render it probable that it is impregnated with a musky smell. Altogether, these are rather singular animals. The length of the canine teeth is a very remarkable character, and one which is somewhat puzzling, as, along with this armature of the mouth, the animals are remarkable for the gentleness of their manners. The fact of the horns being shed only once, or at most twice during the life of the animal ; and if this is fully established, it will be sufficient ground for taking these animals out of the genus Cervus, and establishing them into one entirely peculiar ; but, in the meantime, we want information respecting them. There is no doubt, however, that they have many peculiarities ; and as they are found in so many parts of the East, and with different characters in the different localities, they may perhaps, when better understood, throw additional light on the zoology of the legions to which they belong. It is understood that they are gregarious, and very timid and gentle in their manners ; that they do not live in large herds, but in small packs or families in the woods ; and though they unquestionably partake more of the characters of the deer than of those of any other genus, they are undoubtedly very peculiar, and there are no animals in the east the more perfect his- tory of which would be more desirable. This is the more to be desired, from the fact, that there does not appear to be anything analogous to them, either living or fossil, in any other part of the world. There are many points, however, in their structural history of which we are in a great measure ignorant, and which will require to be cleared up in a satisfactory manner before we can confidently decide whether they are to remain as part of the genus Cervus, or whether they ought to form an entirely new genus. The zeal and assiduity with which the natural history of the East is now prosecuted cannot leave this point long unsettled. The species which we have now noticed comprise all the deer of the eastern hemisphere ; and if we imagine a straight line drawn from Spain to the Island of Timor, all the countries in the hemisphere which lie to the north-east of this line are inhabited by deer, though partially mixed with antelopes in several of the middle regions, while all to the south-west is the proper country of the antelopes. It is true that deer thrive well in the Mauritius and the Isle of France, but they are imported animals there ; and we believe there were no ruminantia in those islands when first discovered. III. DEER OF AMERICA. It only remains now to give a short notice of those species of deer which are found in the American continent, and not in any other part of the world, and we shall take them in order from north to south, though some of them inhabit nearly the same regions. There is, however, some confusion in these species, arising from differences of colour, having been perhaps incautiously made specific. THE WAPITI — Cervus strongyloceros. This species is now well known in Britain, from living specimens being kept in the different zoological gardens ; but it is probable that another described species should be referred to this one, namely, the Canadian Stag (Cervus Canadensis), of which there are also varieties mentioned. We shall quote Hamilton Smith's de- scription of the Wapiti as being the best, both on 264 DEER. account of the describer, and of the fact (a very important one), of his having seen the animal in its native locality : — " Our wapiti resembles the common stag in nearly all his proportions, but his size is far superior, being at the shoulder from four feet four to four feet eight inches, the superiority of bulk appearing chiefly in the magnitude of the body. The hind is similar to the stag, with inferior proportions ; the colour of both in the summer season is fulvous brown on the back ; a black spot on each side of the corners of the mouth descends on the under lip, round the eye brown, and down the face darker ; the neck also is darker than the body, being mixed with a purplish brown tint on those parts ; the limbs are anteriorly dark, and lighter from behind ; under the horns long hairs form a sort of dewlap, also darker in colour ; the buttocks and tail are pale fawn colour, separated from the brown of the thigh by a dark streak ; the tail is short, but varies from two to four inches in length ; the suborbital sinus is long, open and naked next the eye ; the ears are long, lined with white hair within, and dark coloured externally ; inside of the limbs and on the belly the hair is close and buff-col oured. " The specimens seen in Europe appear somewhat different in their colours from those in America, no doubt in consequence of confinement and grooming. The long hair of the throat, and also much of that on the ridge of the neck and sides, dropping off. This description, derived from comparing several living specimens both in Europe and America, is the sum- mer habit. One individual in his winter fur was of a chocolate brown red, mixed with grey, all over the body ; the neck, thickly furnished with long hair, and the woolly soft fur on the forehead, were sepia-brown ; the chin pure white, and the buttocks and tail also nearly white. " Comparing this account with our notes taken on the spot during a winter in America, we find a stag reported to have been brought from the Missouri, but which in reality might have been taken in the north- ern districts of the state of New York, in the vicinity of the great lakes. He was three years old, four feet six inches high at the shoulder ; the nose and legs sepia-black, turning on the neck and back to dun brown ; the croup and tail nearly white ; the body short and thick like the trunk of an ass ; the legs shaped as in a calf, very perpendicular on the buttocks, with appearance of callosities on the knees ; the croup somewhat more elevated than the withers ; the neck much arched and adorned with some long hair, the full expansion of that part not taking place till the fifth year ; the muzzle broad and black ; the eyes dark, and the aspect mild ; the horns were greatly- deformed. On the 17th of February, another sketch was taken of the same animal, his horns were begin- ning to shoot anew, the cicatrix of the former not quite healed, and their form resembling a flattened globe ; his face was covered with woolly hair, ex- tremely thick ; on the side of the hinder legs, near the true heel, a gland imbedded in hair secreted an unctuous fluid, which seemed to cause uneasiness, and we were informed that while the horns are expanding the animal frequently rubs the points of the antlers against them ; the colour of his fur was a sepia-grey, extremely shaggy. This individual was, according to Mr. Skudder, exactly similar to the specimen shot on Long Island, and might therefore be considered the Canadian variety ; and the drawing, compared with v the stuffed specimen in Paris, if it be not the identi- cal animal, closely resembles it. " The horns of this species acquire a surprising de- velopment, expanding with such rapidity that at one period their growth exceeds an inch and a half per day. In the Long Island specimen, of six antlers each measured above three feet in length, and the bur and beam were exceedingly large, but in some individuals they arc asserted to exceed six feet. One specimen, of which we have a drawing1, shows them nearly five- feet long. The base and tertian, or brow and royal antlers, are invariably the longest in both the varieties. These seem to be instruments of use, for with them, when a small dead pine, or a bar of a split fence six- teen or eighteen feet long, lies in their way, they will lift and toss it clear over their backs. " In England, where they have propagated, it appears that some care is required for their preservation, since to an alleged neglect of this kind is ascribed the loss of no less than twelve head of the herd belonging to the king. In Canada they feed on some buds of coniferous trees and grass, and in summer on aquatic plants, which they seek under water while sheltering themselves in that element from the bites of flics. It was in the act of feeding in this manner that we had a view of the Canadian stag. We were in a canoe ascending the Chaudiere, at a point where the river bends suddenly on opening into a small lake. A hunter among us made a warning sign for silence and pointed a- head, but nothing appeared on the surface of the water ; the bateau men, hosveven understood the sign, and grasped their muskets, but with so much precipita- tion and noise as to alarm the game, which now again put his head above water, and seeing the canoe sprang forward towards the bank with his month full of weeds. At this instant he was fired at, but he gained the shore very near us, and dashed with elevated antlers into cover, as was thought, unhurt ; he appeared quite black, with large expanded horns, but no further observations could be made. We were then informed that at this period (August) they are often killed while feeding under water, but the canoe must be so placed as to glide with the current and without noise close to them ; the game only raising its head to breathe from time to time, takes no notice of an object which ap- pears motionless. " On the banks of the Missouri they are said to live in small families of ten or twelve individuals, headed by an old male, who is reported to be monogamous • the rest beside the hind being calves and semi-adults. The females are capable of procreating very early, one born in England having produced a calf at eight- teen months old. This circumstance militates against the opinion of the Indians respecting their longevity. The males do not bellow, but when the}' are alarmed or excited send forth a loud piercing whistle, to all appearance from the suborbital slit. They mew their horns in the latter days of February or during March, and require little more than three months to recover them, notwithstanding their enormous size." — Animal Kingdom, vol. iv. p. 98, &c. From the character of its native country, thore is little doubt that the wapiti might be added to the ornamental animals of this country ; and though it wants the majesty of the stag, the beauty of the roe, and the softness "of the fallow deer, yet its size and the grandeur of its apparel would render it a highly interesting variety in the more extensive parks. NORTH-WESTERN STAG— Cervus occidentals. It is DEER. 265 at least probable that, though the wapiti varies in colour from black to brown, there is another stag, more of a mountaineer, in North America, to the westward of the great central valley ; and though this species displays very considerable variety in the ex- tent of its range, it is probable that it occurs in the Canadian mountains, and is the animal described as the Canadian stag, more uniformly red in the colour, and more light in its make than the wapiti. It has been seen at different parts of the west coast, and perhaps ranges along the Stony Mountains as far as California, its horns are smaller than those of the wapiti ; and it has a character somewhat peculiar, namely, that the bezantler, or second on the beam, is longer than the brow antler. The horns are about three feet from burr to tip, very much furrowed and pearled ; the brow antler turned downwards over the face, the bezantler forwards or upwards ; and the royal, or tip of the horn, consisting of snags from a common centre, as in the stag. There are varieties of colour, but the following is about the average : face dark brown, cheeks and space round the eyes buff, chin and inside of the limbs white, muzzle broad and black, lachrymal sinuses long, ears long, dark outside but inside and margin white, neck, back, Hank and hams brown, legs ochre-yellow, tail in some of the varieties long, in others short. Additional information is wanted, however, in order to determine whether there are several species or only one diversified by climate. THE VIRGINIAN DEER — Ccrvns Firgiwanus. This is what is usually styled the fallow deer of America. It is a very light and handsome species. It stands about three feet three inches in height at the shoulder. The horns are inclined forwards, with their points turned toward each other, so that they arc not further apart than the liases. The burr is small, and near it on the inner side of the beam rises a short antler inclining inwards. The first horn is a simple pricket The second has a forked summit, and then in the fifth year there are two or three snags on the posterior or curved part of the beam. On mature age the upper part of the beam becomes pal mated, and the snags become double pointed ; the burr also extends, and so does the brow antler, but the horns are subject to very considerable varieties. In summer, the hair of hot! sexes is of a bright yellow cinnamon colour, whicl changes to a fine brownish grey during the winter the hairs of that season being annulated with brow and buff. The belly, inside of the thighs, the inter nal face of the fore legs, above the knees, and the posterior, inner border of the buttocks, are white the throat, breast, and under part of the tail, of th same colour ; the upper part of the tail dark, and the legs fawn colour; the ears are long and pointed, out side of a brown grey, inside well lined with white hair; the forehead, face, and cheeks, brown with slight mixture of grey ; round the eyes, lips, and chin fawn colour ; the muzzle small and black, no spot o the corner of the mouth, but the winter hair of th belly and under part of tail long and silky, and th bristles on the inside of the hinder joint or tibi-tarsa articulation of a deep rust colour. In this animal th eyes are peculiarly bright, soft, and beautiful. Th fawn is of a lively fulvous brown, marked during th first year with numerous white spots. They rut i November and December, when the neck of the buc swells, and gestation lasts near nine months, th females dropping two or even three fawns. The buck ose their attire about the same period as the stags f Europe ; they bray, but with less noise, and live in erds from the southern confines of the great lakes nd the St. Lawrence to the Floridas and westward, n the interior to an immense distance. According o Professor Harlan, this species displays great enmity ovvards the rattle-snake,, which it contrives to crush y leaping, with the fore-feet conjoined, and dropping lerperidicularly on the serpent, bounding away again vith great lightness, and repeating this attack till the ineiny is killed. This species of deer is subject to con- iderable variations, probably arising from difference of tolour, but the specific distinctions are very uniform. [ts flesh is very palatable and wholesome, and its skin, which is soft and flexible, is used for many purposes n domestic economy, and is said to resemble that of the chamois more than the skins of any of the com- mon deer of Europe. It is altogether an interesting animal, and forms a very decided feature in the natu- ral history of the districts in which it is found. It is rather more of a lowland animal than the red deer of the Rocky Mountains, but it possesses more elegance of form and more activity of habit than our fallow deer, at the same time its manners are gentle, and there is no doubt that it could be easily domesticated in its native country, and probably in Europe. THE MexiCAN DEER — Cervus Mexicanus. This is rather a doubtful species, or at all events the part of America of which it is a native is not very clearly made out, though it is probable that it inhabits the table land, more or less, the whole way from Mexico to the southern extremity of the American continent ; and that though it is a mountaineer in the tropical parts, it descends to the plains in Patagonia. The animal itself is little if at all known, but the horns have been in various museums for a considerable time ; and as they are peculiar, it may not be amiss to give in substance the description of them, partly from Shaw and partly from the celebrated Grew, by whom the animal is styled the Indian Roebuck. It is probable that the same pair of horns still to be seen in the British Museum are those mentioned by Grew. They are of a bright yellow colour, so irregularly and widely palmated as to cause a suspicion that they once belonged to an unknown species of reindeer, or to a second species of elk. They are nearly seven- teen inches long, spreading diagonally from the head and reclining back ; there is no burr at the base, only a broad, ascending, tuberculated, and toothed beam. At two inches from the base an antler issues from the anterior part in a vertical direction, flat and ending in two points ; about three inches higher the beam, being somewhat prismatic in form, widens, and a broad flat branch throws up four snags in the form of a palm, the foremost plain, the next toothed, the third plain, and the fourth bifurcated ; behind these a fifth assumes a still more singular form, it ascends in the same direction with the others, terminating in three processes, and from its external posterior side throws out an horizontal branch which bifurcates again, the inferior being the longest and hanging downwards ; this is the right horn ; the left, after the basal antler, throws obliquely forwards a flat broad branch dividing into two processes, then vertically one with three ex- ternal processes, and then a third likewise with three external processes, but these three branches flatten also at the base into a kind of palm obliquely facing the other. Cuvier describes the horns as strongly curved for- 266 D E E R. •wards, spreading outwards, and converging towards each other at the extremities ; an antler at the ante- rior face of the beam, pointing vertically, and furnished with strong denticulations ; a spiller or antler at the posterior part of the beam, divided into several small branches ; these horns flatten into a sort of palm from the second antler, and at their base are deeply grooved and strongly tuberculated. The head which Cuvier describes is that of a very old specimen, which was furnished with a muzzle, but had uo canine teeth ; and in these and other partkulars it appears that the animal bears so strong a resemblance to the Virginian deer, that it is probably only a variety, and that this deer extends throughout all the temperate parts of America, being subject to some variations arising from differences of climate and pasture. The follow- ing are descriptions of some of the museum specimens of the horns. In the collection of the late Mr. Brooks there was a pair of a bright golden yellow colour, very robust, rising from the burr with strong pearls, and" a small antler in front ; behind this, and in con- tact with it, a second snag, strong, vertical, notched, and grooved ; the beam then bends out at an angle, horizontally and laterally, and then curves forward. On the superior edge are three bifurcated snags, two vertical, and the third bent forwards ; but what seems to confer a decisive character on these honis is, that beneath these, on the inferior edge of the beam, a sixth heavy snag hangs down perpendicularly, widened and flattened at the base, and evidently much worn by friction, while the animal grazes ; this is the character on the left ; the right is similar, except- ing the extreme points, which appear to have been injured in the development. In the British Museum, there is another similar pair with the worn clavate sus- pensal snags, but less in proportion. These two speci- mens seemed to justify the appellation of Cervus cla- vatus for a new species, but they are the companion of several others in the British Museum. There are, however, so many uncertain points in the history of this species, that it must be received with much caution. THE LARGE-EARED DEER — Cervus macrotis. This is also an American species, resembling the Virginian and Mexican deer, and also in some respects the wapiti ; but according to the descriptions of Harlan and Say, it is different. The upper part is light red- dish brown, and the sides and tore part of the nose ash colour ; the back intermixed with blackish tipped hairs, which form a distinct line on- the neck near the head ; tail reddish-cinereous black at the tip ; this part is somewhat compressed, and almost naked be neath ; the hoofs are shorter and wider than those o the Virginian deer, and more like those of the wapiti the horns slightly grooved and tuberculated at base with a similar antler, as in the Virginian ; the beam less curved forwards, is bifurcated near the summit again divided, the anterior of the second bifurcation being somewhat longer than the posterior ; the ear very long, extend to the principal bifurcation, abou half the length of the whole horn , the lateral inciso teeth are larger in proportion to the intermediate than in the Virginian ; eyelashes black ; lachrymal aperture also larger, and the hair coarser, and undulated, an< compressed like that of the wapiti. The species i found in the most remote north-western territories o the United States, and from the context of this de scription it appears evident that the Guazupuco dee is nearest allied to it, and that the guazuti and th Virginian are clearly of the same group. THE LONG-TAILED DEER — Cervus macrourus. This pecies is described as being larger than the red deer jr stag of Europe, darker in colour on the upper >art, and having the belly white, the tail, from which t gets its specific name, different from that of most pecies of deer, is about eighteen inches in length, )lack on the upper part, but with broad white mar- gins, and carried erect when the animal runs. The Cervus macrourus. horns are short, and altogether of small size and flat- tened, but not palmated. This species of deer is described as being very numerous in the dry plains near the banks of the river Kansas in North America. This river is one of the western branches of the Missouri, and drains by its different forks a region of 500 miles in length by more than 100 in breadth. THE GOAZUPUCO DEER — Cervus paludosm. This species inhabits the low and swampy regions of South America, and is described by D'Azzara as having horns rather large and cylindrical, terminated by a fork, with an anterior antler some way up the beam, simple or bifurcated, pointing forwards and then ver- tical ; his muzzle is large, figured like that of an ox ; the eyes large and full, with a lachrymal fold beneath ; the forehead below the horns flat ; the ears terminat- ing in a point ; the pedicles of the horns are one inch high, and the horns about one foot four inches in length, with never more than five snags ; mammae four, disposed in a quadrangle ; the eyelashes black, surrounded with white, which passes along the side of the face, and surrounds the muzzle and the mouth ; a black velvety spot in the angle of the lower lip, another shading the nose on the upper ; a black trian- gular one on the nose, and another between the eyes, united by a dark line between them. Inside of the ears, under jaw, and cheek, white ; a black spot on the interval of the hoofs of all the feet, ascending to the second joint ; a black band passing along the breast, and another en the upper part of the tail. The size of this animal is nearly the same as tbut of DEER. 267 the European stag, being four feet high at the shoul- ders, and four inches higher at the crupper. The prevailing colour on the upper part is reddish bay ; the tail is of medium length, and I he two incisive teeth are larger than the rest. The females are smaller than the bucks, and without the black line on the breast. The fawns are ot a uniform dun colour, and without any spots. The hair on the posterior part, of the abdomen, and all the way between the hip and the under side of the tail is very long, white for the greater part of its length, but with dark points. This species is most abundant in the swampy regions of Paraguay, in the centre of South America, and according to the account given by D'Azzara, the season of rutting and also that of shedding the horns are not so determinate as in the deer of the northern hemisphere. This is not to be wondered at, if we consider the character of the country which these animals inhabit. When the rains set in, a very great extent of the surface is laid under water, by which means the deer are dispersed to the margins of the temporary lakes, where they find abundant food ; and as the dry season comes on, and the waters subside, they retreat upon the remaining portion of the marsh, which is seldom dried up even in the hottest season. These animals may, therefore, be regarded as enjoy- ing a perpetual summer ; and, therefore, as is the case with most animals which enjoy this, their breed- ing is not confined to one particular season, but is distributed over the whole year. We still know too little of the natural history of South America for being able to decide with precision the geographical situation of this or any other species ; but it is pro- bable that the one under consideration is very gene- rally distributed over all the swampy grounds. THE GUA/ETI DEER — Cervus campestris. This is also a South American species, but inhabits the dry plains rather than the bushy margins of the marshes. This is smaller than the former species, being only about two feet six inches at the shoulder, and two feet eight and a half at the croup ; the horns are a foot long, slender, with the beam suberect, a branch ante- riorly placed, bent upwards, and posteriorly one or two snags towards the summit ; the eyes are large and brown, with a suborbital fold ; the ears erect and pointed ; the fur smooth and close, is reddish-bay, the hair being reddish-bay at the point, and dull brown at the base ; the inferior parts of the body, the under side of the head and tail, which measures six inches, are white, as also the hinder part of the buttocks, and internal face of the thighs, a circle round the eyes and inside of the ears. The hair on the lower part of the abdomen is not so much produced as in the species last described. It is understood that this species is also very gene- rally distributed over South America, and that it is particularly abundant in Patagonia, the plains and valleys of which are much more perenially green than those of the more tropical parts of America. It resides in the open plains, is remarkably swift ; and the male emits, when pursued, a strong smell of onions ; which, however, is supposed to result more from feeding on bulbous roots than from any natural quality in the animal, as some specimens which have been kept alive in Europe and fed upon grass, have not emitted the same odour. The horns of this, and indeed of most of the South American species of deer, are, however, subject to so much variation, that there is some difficulty in making them out. The horns of deer are, indeed, perplexing matters. As we havo already said, there are, at least, ten times as many pair of horns as deer ; and these pairs are not only all different by nature in different years, but they arc liable to accidental differences from hurts or other- wise ; and we have further reason to believe that not only difference of climate varies them, but that they are farther varied by differences of seasons. They are seasonal productions, as well as annual plants ; and the feathers of birds are, and we know that these are, affected by the character of the season. Farther we know that, in the same species, and even in tb« same group of deer, the horns are less produced in warm climates than in cold ones ; and it follows, by parity of reasoning, that they should be less produced in warm seasons than in cold ones. These and many other circumstances render it very questionable whether the form of the horns ought to be taken as the characteristic of the different species of deer ; and it is certainly true that much perplexity has been occasioned by the horns of the less known species, and particularly by shed horns, the owners of which are altogether unknown. THE CABIACOU DEER — Cervus nemoralis. This species is considered as a variety of the Virginian deer ; though it is understood to inhabit more south- erly latitudes, being abundant in the woods of tropical America. In the United States this animal is called the roebuck ; and it bears considerable resemblance to the roebuck of the eastern continent. The following is Hamilton Smith's description from specimens, of Virginian origin, which were kept in the hospital gardens at New York : " The horns not more than eight inches long, somewhat vertical, rugous at base, with a small antler not above an inch in height, rising vertically at a short distance up the anterior part of the beam, which at the insertion of the antler, bent back, and then being slightly flattened, turned inwards and forwards in a slightly uncinated bend, throwing oft' a posterior short snag, which constituted a bifur- cation ; the buck and does were nearly of the same size and colours ; the head rather round, not so pro- longed as in Guazeti, and the body longer than the roebuck, about twenty-eight inches high at the shoul- ders and thirty at the croup ; the neck, shoulders, sides, and back, were of a yellowish brown grey ; the inferior part of the belly, edge of the buttocks and under tail white; the face darker brown grey ; leaving the region round the nose, lips, and chin likewise white, with a black spot on the nose, one at each side of the mouth, on the upper lip, and one at the corner of the lower lip ; the space round the orbits and cheeks, dun, with a little whitish favour behind the eye ; the ears moderately long and pointed, were brown-grey outside and whitish-grey inside ; the eyes full, dark, and soft, with a small suborbital fold beneath ; the muzzle small, round, and black : from the knees downward to the fetlock was a dark streak, but the rest of the limbs ochry ; and the tail about four inches long, was dusky above, without any long- white hair at the edges. " While engaged in making the sketch, they were fed with bread, and the buck, jealous of the does sharing the dainty, showed his propensity to leap, for he drove them off by butting them, the head turned sideways, not unlike a goat in play, rising for the purpose high upon his hind legs, and not by running with the head low like the stag. It being in the month of March, their mewing period, he broke one 268 DEER. horn oft' in this sport, an .. then made several surprising vertical bounds, but only one drop of blood escaped from his head, and he stole away in a crouching gait under a shed. " This species is common in all the warmer parts of the American continent which abound in forests. The mahogany-cutters of Belise often meet with it in the woods. It is very lively, but at the same time a most gentle creature, easily tamed, and very familiar in confinement. We are still, however, in want of information respecting it, and also several others of the forest deer of America, the haunts of which are very difficult to explore." Besides the species which have been enumerated, there is an entire group of deer on the American con- tinent which differ altogether in the form of their horns from the deer of the eastern world, as well as from those species which we have described. They are generally styled brockets, from the circumstance of their horns never acquiring any branches, but remain- ing as single dags, similar to the prickets or first horns of the European stag. The deer of this group are mostly of small size and light make ; they are very numerous in some parts of the country ; and as the females very much exceed the males in numbers, it has sometimes been alleged there are species of deer in America the males of which have no horns. This is certainly, not true, but the horns of this group are insignificant as compared with those of most of the genus. The animals themselves are generally below the middle stature of deer ; their nose is pointed, and their muzzle small, consisting of a glandular termina- tion at each side of the nostrils. Their lachrymal sinuses are small, and their colours are generally uniform, the prevailing one being bright reddish brown. They inhabit the thick swarnpy forests, and are found only in the warmer parts of the continent. Several species are mentioned, but we are in want of precise information respecting them. THE PITA BROCKET — Cervus rufus. This is a very lightly formed and handsome animal. The male or buck is styled Giiaru Pita in Brazil, and it is rather taller than the roebuck of Europe, but more lightly made. The head is very pointed, and the muzzle small, but giving an enlarged appearance at the sides of the nostrils. There is a lachrymal sinus before the eye, and the male has canines ; the horns are always simple with a small burr at base, and the pricket about five inches long ; the body is of a lively red- dish bay, excepting the face and feet, which are red brown ; the lips, chin, surface between the under jaws, under part of the tail, and lower abdomen, are white ; the throat and internal face of the thighs whitish grey ; the tail with the hair is nearly nine inches long, and red bay above ; a circle round the eyes is occasion- ally paler than the rest of the head •. the females have the same colours, but are smaller in stature. These animals are found chiefly or entirely on the eastern side of central America, from Honduras to the south- ern extremity of Brazil, along which line the low country is generally very much wooded, and therefore adapted to their habits. They are gregarious, living in large herds, and are almost the only ruminating animals which are so, and at the same time of a strictly forest character. The males are polygamous ; and, as already mentioned, their numbers are few compared with'those of the females. They are much preyed upon by the aguars, and also by the larger species of boa. " The APAUA BROCKET— Cervus simplicicornis. This is a smaller species than the former, standing only about two feet and a half at the shoulder, and being, as is understood, destitute of canine teeth. The pro- file is remarkably straight, and the horns, which are small and shorter than the ears, are continued in the same line with it. This is a red deer as well as the other, but its colour is brighter, its tail shorter, and furnished on the under side with longer hair. There is a dark ring round each eye, and the mouth is dusky. The specimens of this species which have been exa- mined and described in Europe, have been chiefly brought from Brazil, where they are understood to inhabit more on the open plains than the species last described. They appear to vary very considerably in their colours with age, so that there is some uncer- tainty about their natural history. The BIRA BROCKET — Cervus ncmorivagus. This as its name imports, is a wanderer in the woods. It has sometimes been confounded with the apara, but it ;s a much smaller and more gentle-looking animal. It is only about a foot and a half high at the shoulder. The horns are straight, smooth, solid, and pointed ; rather more than half an inch in diameter, and not exceeding two inches in length. The tip of the ear is rounded, and the lachrymal sinus is very small. General colour on the upper part greyish brown, the hair being brown, with yellowish white points. The lips, the chin, and the middle of the breast are white ; the belly, the whole of the fore-legs, with the excep- tion of the outside of the knees, and a space round the eye are buff coloured, the outsides of the hind legs are fawn ; the animals are remarkable for the gentle- ness of their appearance. The species of which we have given an enumera- tion comprise at least the greater number of living deer which now inhabit the earth, though it is by no means improbable that in America, both North and South, in the central mountains of Asia, and in the Oriental isles there may be species with which we are not acquainted, and it is possible that some of those which are now described as species may be only acci- dental varieties ; for most species, and particularly those of the warmer climates, are subject to albinoisrn, and also to occasional differences in the forms of the horns. There is no genus of animals more interesting to the naturalist, in every point of view, than the deer. With the exception of Africa and New Holland, they are found upon every large portion of land on the surface of our globe ; and they appear to have existed coeval with some of the races of animals which are now extinct. They have even a fossil history, to which it is of some consequence to attend ; and for this purpose we shall briefly mention the principal ones whose remains have been found in the earth. FOSSIL DEER. The most remarkable of these is probably that which has been so frequently met with in the bogs of Ireland, and which has been styled the IRISH ELK from the form of its horns, though in the rest of its anatomy it approaches more to the charac- ter of a stag. The horns of this fossil species so far resemble those of the elk, that they have large palms which are placed edgeways to the front, and extend wide in a horizontal direction. But they differ in the number and extent of the snags upon the posterior margins of the palms, not being more than eight or ten, while in the mature elk the number is sometimes as many as forty. They differ also in having a brow DEERINGIA— DEILEPHILA. 269 antler projecting from the beam of the horn imme- diately over the burr, which antler is enlarged towards its extremity in all the specimens, and in some of them it is forked. It is understood that these deer in so far resemble the reindeer as that both sexes were fur- nished with horns, and horns of immense dimensions ; the entire length of some of them, including the por- tion of the cranium between, being not less than ten feet. But though the horns are of this immense size, it does not appear that the animals themselves have been proportionally large ; for the bones of the head are not larger than those of a full-grown stag. This species appears to have been very numerous in Ire- land, three heads having been found in a single acre; and Molyneux mentions that in less than twenty years thirty had been picked up. These animals have been contemporary with the fossil elephant, which is now extinct as a living inhabitant of Europe ; and though they are more abundant in Ireland than any- where else, they are by no means confined to that island ; they have been, however, found in the Isle of Man, and several parts of Great Britain, in France, on the banks of the Nile, and in the valley of the Po ; and there is no doubt that proper research would find them in many other parts of Europe ; so that we have every reason to conclude that at some very remote period of history, when the state of the country was very different from what it is now, they were very generally and abundantly distributed. Another fossil species is the fallow-deer of Scania, in Sweden, mentioned in the memoirs of the academy of Stockholm, for 1802. These bones, which were found in a fresh water deposit, arc much larger than those of the existing fallow-deer ; and yet they ditier so much from the horns of the reindeer that they can- not be referred loan accidental variety of that species. They have a single brow antler upon each horn, placed on the beam, between four and five inches above the burr, but small and perfectly simple, and thus totally different from the antlers of reindeer, while the palms of them are vastly larger than those of the horns of fallow-deer. In the south-west of France there are found the remains of a deer bearing very considerable resem- blance to those of the reindeer of the present day, but the animal itself has been considerably smaller, not exceeding the common roebuck. These remains are found in the sands of Etampes, and also in caves, at Breugens in the department of the Lot, at which latter place they are mingled with the bones of the horse, the rhinoceros, and various other animals. The horns stand more erect than those of the reindeer ; and though there are several points of resemblance, there is question that the owners of these remains have belonged, if not to a different species, at least to different variety, from the common rein-deer. The existence of those remains in the same charnel-house with the bones of the rhinoceros, is a singular and somewhat puzzling point in the natural history of our globe. The reindeer is now found only within the arctic circle ; and the rhinoceros only in tropical countries. The fact of their remains being found to- gether, leaves no doubt that they have been co-inha- bitants of the temperate parts of Europe. Thus the geologists are put upon the horns of a dilemma ; be- cause neither the assumption that Europe was once colder than it is now, nor that it was once warmer, will meet this case, in as much as, so far as our present knowledge extends, we have the remains of the polar animal and the tropical in the same grave. In the fresh water formation of calcareous matter at Montabuzard, there are found the remains of a species of roebuck, together with two species of lophesdon, and one of mastodon, both of which are now extinct, in all parts of the world ; so that we know nothing of the kind of country which was adapted to their habits. This fossil species resembles, in many respects, the deer of the Oriental islands, and more especially the deer of Timor, which is the most remote from Europe in its habitat of any with which we are acquainted. On the deposits near the northern shore of the Mediterranean, there are also various species of deer, some of which resemble the deer of the eastern islands ; and, what is singular, their remains are mingled with those of timers and panthers, which are now natives of warm countries only, as well as with those of the Alpine hare, which are now found living in only the coldest regions of the world. These particulars are highly curious ; but they set all our theories at defiance, and render it impossible to say probably what may have been the condition of Europe at some former period of its history. DEERINGIA (R. Brown). A genus of East Indian biennial herbs, belonging to the natural order Ainaranlhacca;, and nearly related to the Cclosia or cockscomb. DEILEPHILA (Ochsenheimer). A genus of lepidopterous insects, belonging to the section Cre- piiscularia, and family Sphmgidcs, or hawk moths, having the wings entire and acute, the spiral tongue rather elongated, and the antenna: short, and gradually hut distinctly clubbed in the males. These insects have much the appearance of the insects to which the genus Sphinx is restricted by recent authors, but the species are generally smaller, and more robust in appearance, owing to the comparative shortness of the abdomen. Mr. Stephens divides the genus " into two sections, corresponding with their diversities of habit and structure ; the larva; of the second section have the power of elongating or contracting the anterior portions of their body, thence called elephant sphinxes — a term which has been applied to all the species, but improperly." In addition to the external characters of the perfect insects, by which these two sections are distinguished, it may be added, that in the first of them, the caterpillar is completely covered with minute pale spots upon a dark ground, its anterior segments are not capable of being pro- truded to a considerable distance, and the horn upon the extremity of its back is rough, and the chrysalis is superficially buried ; whereas, in the second section, the caterpillars are not minutely spotted, a large eye- like spot appearing on some of the front segments, which possess a very considerable power of pro- trusion ; the horn upon the back is smooth, and the chrysalis enclosed in a cocoon of leaves on the ground. There are eight species of this fine and handsome genus indicated by authors as natives of this country, but two at least of them appear to have been species introduced with imported plants. Of these the D. celerio, which feeds upon the vine, has been the subject of much controversy amongst entomologists, amongst whom Mr. Stephens (Brit. Ent. vol. i. p. 128.) who contends against, and a writer in a late number of the Magazine of Natural History, who argues in support of their introduction as reafinhabitants of this country, may be especially 270 D E LP H AX. noticed. The following observations upon the Ui-i/e- phila Euphorbia:, one of the rarest and most beautiful species of the whole section, will, we are sure, be read with interest. This species is found upon the sand hills of Braunton Burrows, near Barnstaple, in Devon- shire, in the month of June. On its first appearance the wings are small, clumsy, shapeless appendages, and are more soft and yielding than the lightest silk which undulates with a breath, often remaining for some time stationary in a vertical position upon the stem of the spurge, allowing its wings opportunity to expand and strengthen as they droop behind it. In half an hour the wings are brought forward, and assume their usual position. About half an hour after sunset the Deilephila appears on the wing, circling over the various branches of spurge scattered over the surrounding waste, until a mate is found. The eggs are coated with a gummy substance, by which means they are easily attached to the small leaves of the spurge. They hatch in a fortnight, producing small black caterpillars, which shortly afterwards acquire a red head and tail*. Subse- quently they grow very fast, gaining at each moulting additional beauty, by having red dorsal lines, and a great number of minute yellow spots, two lateral ones on each segment* being much larger. When full grown, Mr. Curtis informs us that " they are so conspicuous, that their numbers are reduced by marine birds which feed upon them ; they are full grown about the middle of September, when they descend into the sand, and become chrysalides, forming a loose case of earth around them, from which the moths emerge the beginning of the following June. Some- times, however, they remain in the pupa state two seasons, as many lepidoptera do — a wise provision of nature to prevent any accident from destroying the •whole brood. The sand hills where the larvae are found being of great extent, must have been collected by the winds and storms, to which they are constantly exposed. During the winter the whole soil is fre- quently removed so as completely to alter the surface of the country. A great number of the pupae must consequently be destroyed, or buried at a considerable depth below the surface, where probably they lie hid until they are brought to light and life by the influence of the elements." — Brit. Ent., second edition. These circumstances mentioned by Mr. Curtis will enable us, in some degree, to account for the irregu- larity in the appearance of these insects mentioned to the author of this article by Mr. Raddon, the gentle- man by whose exertions the majority of specimens have been obtained, and since published by him in the Entomological Magazine. Since 1819, he has, however, been unable to obtain but a single chrysalis, and the person by whom this was found informed that " the valley in which you desired me to search is completely filled up by the sand, and the whole surface completely altered by the wind." The late Captain Blcmer was not able to capture one, although he resided some years upon the spot ; and Mr. Cocks, in a letter to Mr. Raddon, says, " it is now ten years since I took the larva, and although I have regularly been in the habit of visiting the locality every year several times, 1 have never been able to take it since ;" although, in 1814, they were so plentiful, that Mr. Raddon found not less than a hundred minute larva; * Abridged from the Entomological Magazine, No. 9- upon an armful of spurge, which he hud cut at dusk the preceding evening. The rarity of the insect is also greatly increased by the difficulty of rearing it. The late Mr. Fuseli, the lloyal Academician, who was a zealous entomologist, was enabled only to obtain one moth from upwards of twenty chrysalides. The only species abundant in the neighbourhood of London is the 1). Elpcnoz, the caterpillar of which feeds upon the ladies' bed-straw in Hackney marshes, Battersea Fields, &c. DELPHAX (Fabricius), a genus of homopterous insects belonging to the family Fulgoiida;, having the antennae inserted in a notch on the lower margin of the eyes, and being about as long as the head, with the first joint shorter than the second. The ocelli are distinct ; the head is produced in front into a short pointed and flattened snout, and on its underside it is elongated into a tubular proboscis, directed towards the breast, and which is the instrument by which tlie insects are enabled to inflict wounds on the leaves and twigs of plants, and to suck up the fluid which flows therefrom. There are numerous British species belonging to this genus, of small size, found amongst grass and rushes, some of them occasionally do not have their wings developed fully : whereas the same species in certain seasons, and under peculiar circumstances, of which we are unable to ascertain the nature, acquires full-sized wings and wing covers, which latter are, however, not more coriaceous than the former. Mr. Curtis, not aware of this remarkable peculiarity, has formed the subapterous individuals into a distinct genus, under the name of Criomorphtu. One species of this genus, the Delphax saccharivora, or the Cane-fly of the West Indies, is exceedingly injurious in its ravages upon the young and growing sugar-canes in Grenada, and some other of our Went Indian possessions. A correspondent of the Magazine of Natural History (vol. vi. p. 407), thus describes the nature of its attacks : — " For these last six months, (back from March 1833), the island of Grenada has been infested with a species of insect that threatens not only great injury to the present crop of sugar-cane, but also to render the labours of the planter entirely abortive for the next crop. I am not aware that any species of insect hitherto noticed has been found so formidable, either in number or destructive qualities, as the cane-fly, which is now propagating, and so rapidly over-running the sugar plantations in this colony. The insect, formed with a snout and beak ending in a bristle, attacks the cane in all stages of its growth, but is more particularly injurious to plants or ratoons when they are young and tender. The under surface of the leaf, and towards the mid-rib, or the course of the larger sap vessels, is selected by the insect for the scene of its operations. There it makes an oblique puncture, resembling that which would result from a lancet introduced in the same direction. Into each of these punctures from five to fifteen eggs are deposited, and each egg is placed transversely with respect to the direction of the fibre of the cane, which serves to overlap them, and thus afford a pro- tection from the many enemies they have amongst the insect race. The aperture is then covered by a very slight substance, resembling that which protects the eggs and young of various species of spider. This substance is always to be observed attached to the posterior part of the body of the insect. When the insect appears on the surface of the leaf after its DELPHINIUM — DENTAIU A. •271 first tvaiisl'ormation, it seems dull and inactive, and is generally covered with a light floss of the substance already mentioned ; but having changed its skin, which it leaves perfect and attached to the leaf, it becomes lively, active, and voracious, and joins in the works of propagation and destruction. There can be no doubt, or at most but little, that the Aphides (as the writer erroneously termed the insect to which they, indeed, bear much resemblance in their habits), do not select the sugar-cane merely as a medium for the deposition of their eggs, but that, like millions of other creatures, they also regale themselves with its sweets, and from their numbers, literally to bleed the plant to death. — Like most of its tribe, it produces the substance called honey dew, so much so, that the upper surface of the leaf infected is covered over with it. This substance when dry, becomes black and of a light texture, which being nearly insoluble in water, destroys and interrupts the action of the atmosphere, and aids in the general destruction of the plant." DELPHINIUM (Tournefprt). An extensive genus of herbaceous plants, natives of many different parts of the world. Linmean class and order Poly- andria Trigynia, and natural order Rdiiiniciilacece. Generic character : calyx corolla-like, of live sepals, the upper one spurred ; corolla of one or four petals, the upper one having a posterior horn, the lower sometimes cleft ; stamens below the germen ; filaments dilated at the base, and short ; anthers terminal, oval, two-celled, cells bursting outwardly ; styles three or five, and short ; stigma cmarginatc ; capsules one, three, or five, having membraneous follicules, and with a placenta fixed to the suture ; seeds angular and albuminous. From the peculiar form of one of the petals, these plants have received the English name of larkspur, and whether annuals or perennials have always a place in flower gardens. The first are every year raised from seed, the second are increased by dividing the root. The flowers are not only re- markable in form and variety of colours, but also for the intensity of their various tints ; the double D. grandiflorum is perhaps the deepest blue of any flower we possess. DELPHINULA (Lamarck ; TOKBO-DELPHINUS, Linnaeus). This genus of shells, possessing the round aperture of the genus Turbo, probably induced Lin- naeus to consider it of that family ; but the united mar- gin of the mouth at once distinguishes it from the tur- bines. In many respects it approximates to the genii Scalaria, like which it has its whorls sometimes drawn out and detached ; but its nacreous substance, in ad- dition to the following distinctions, clearly proves it a not allied to the family. The shell is solid, conical, or sub-discoid, umbilicated, thick, pearly within and under the external coloured coating : the aperture i entire, round, or sometimes trigonal ; the whorls of the spire rugged on the outside, and angular on the side of the umbilicus (which is filled with short spines proceeding from the interior side of the whorls not observed by Lamarck), no columella is visible, a cal- careous operculum externally tuberculated, which also Lamarck presumed to exist, but probably had not seen ; the exterior of the whorls is armed with spines depressed and singularly palmatcd at the summits tubercles, or scabrous striae, which we have said, give it a ragged appearance. Its pearly substance proves it a marine shell, and distinguishes it from the terres trial genus Cyclosioma, though its rounded opening would otherwise entitle it to be ranked with them, ir o far as that distinction holds good. Common as this hell is, it is remarkable that the animal is unknown, mt every reason exists to rank this genus in the second ;lass, ParacfpJtalop/wra ; second order, Asiplionobran- •hiata -, second family, Cricostoma. It appears to occupy natural position in following the genus Turbo, and, receding the genus Turritella. All the known species nhabit the Indian ocean, and abour four are described. There are, however, more known in a fossil state. De France, indeed, enumerates thirty in the formation irior to the chalk stratum. DEMETKIAS (Bonelli), a genus of coleopterous nsects, belonging to the section Pentmnera, family Carabldec, and sub-family Bruchinidcs, having the body ong and flattened, the tarsi have the penultimate oint bilobed, the chin is obscurely toothed in the centre, and all the palpi have the last joint rather dilated at the base, and pointed at the extremity. There are but few species of this genus which seems to be confined to Europe, two only are British ; the ype, Carabux atricapillus (Linnaeus), is of small size, and chiefly found under the bark of trees. It is of a .nifT colour, with the head and breast black, and thorax reddish. DENDROBIUM (Swartz). One of the most elegant of the epiphytes found in the East Indies and New South Wales. It belongs to the class and order Gi/namlria Monandiia, and to the natural order Orc/ii- dcec. It may be increased by division of the root, and though its natural station be on the stems of trees when wiM, it grows well in pots of moor turf. It thrives best in a moist stove, and flowers frequently. DENTALIUM (Linnaeus, and modern authors). This very singular genus of molluscs is so generally well known that an elaborate description of them would be superfluous. The shell is a conical testa- ceous tube, nearly regular, slightly curved, gradually attenuated towards the posterior end, and open at both extremities, resembling an elephant's tusk in miniature, whence its name. Some species are lon- gitudinally ribbed, others with slightly marked annular ribs, formed by the different stages of growth ; but the greater portion of these shells are smooth on the exterior. The animal's body is lengthened, subver- miform, enveloped in a fistulous mantle, terminated by a belt or thickened band, pierced in its centre by an orifice with fringed edges ; the foot altogether an- terior, probosciform, terminated by a conical append- age, received into a species of cup with festooned edges ; the head is distinct, oval, a terminal mouth in the middle of a digitated lip, a pair of lateral jaws armed internally with very singularly formed dental processes. The D. elepkttntininn illustrates the spe- cies having ribs or striae longitudinally placed ; the 1). cnlnlis those which are nearly smooth, or merely presenting the striae of progressional growth ; and to these may be added such species as are narrowed towards their orifice, and the interior doubled bv another tube, forming DC France's genus EntaHiiw. The precise position these molluscs should occupy in the system of malacology cannot at present be finally determined upon, as a further examination of the animal is indispensable. The comprehensive mind of the great Swede suggested their being allied to the Carinaria and Patella, and modern authors have there- fore placed them provisionally in the third sub-class Ptmtcephalophara fiermaphrodtfe, first order Cirr/io- branchiala. DENT ARIA (Linnaeus). A genus of tuberous 27.2 DEODARA-DESMODIUM. rooted herbs, chiefly natives of Europe. Linnueau class Tclradynamia, and natural order Cruclferte. These plants are nearly allied to Cardamine, but differ in having tooth-like scales at the root. They grow readily in light soil, and are increased by dividing the roots. DEODAR A. The specific name of a cedar found in India by Dr. Roxburgh, and introduced into this country in 1822. DERMESTID^E, a family of coleopterous insects belonging to the section Pentamera, and sub-section Nccrophaga. This family is of small extent, but com- prises several very obnoxious species of beetles. The body is generally oval, rounded at each end and some- what convex, the antennae short and clavatc, sometimes varying in the sexes ; the legs short, with the tarsi five-jointed, and not contractile as in the Byrrhidce, the tibia being long and narrow. The genera are Dermestes, Ctesias, Mcgatoma, Attagenns, Limnichus, Trogoderma, Globicornis, and Anthrenus. The last named genus, as well as Aspidiphorm and Throscus, seem to unite this family with the liyrrliidae or pill- beetles, with which they are associated by some authors. Of these genera the only one which offers any interesting observations in respect to their econo- my, is the first, which is the type of the family, and which has received its name from the circumstance that the species of which it is comprised especially attack dried skins, the Greek word derma signifying a skin. The mischief which they thus often occasion to very costly materials, has occasioned them to be well-known. The perfect insect, on the contrary, seems only to live for the purpose of continuing its kind, being often found upon flowers, and if it fre- quents animal matter, it is only in order there to deposit its eggs instead of producing fresh ravages. It is chiefly in collections of natural history, and in the warehouse of the furrier, that these injuries are committed ; in the former they entirely destroy pre- pared beasts, birds, and insects, and in the latter all kinds of skins, of which they gnaw the surface so as to cause the hair entirely to fall off. They also attack the carcases of animals exposed in the fields, devour- ing all the fleshy and tendinous parts, so as to make perfect skeletons of their prey. They also feed upon bacon (whence the name of the typical species Dermestes lardarius), feathers, horns, &c. Indeed, it is difficult to guard against their attacks : they elude our search by their small size, and our precautions by their perseverance. Nevertheless, in the great economy of nature, it cannot be denied that these animals tend towards the general good by destroying those kind of putrifving matters, and converting them into a material serviceable for the support of plants, inasmuch as that the air and moisture do not come into action towards the same end so quickly. With the assistance, therefore, of the Silphce, Histercs, We- crophagi, &c., these insects effect the i eduction to their former elements of such portions of carcases as the flesh-fly has spared, which attacks only the flesh when in a fresh and moist state, and leaves the skin entire. The Dermestidce seem to prefer dark situations, where they remain inactive, and move only when disturbed, with a trembling kind of gait ; they are seldom seen on the surfaces of the substances upon which they feed, but conceal themselves. The larvae are long, diminishing towards the tail, and terminating in a trun- cated cone, having, also, two scaly horns on the last segment of the body ; they are covered with long hairs, and have a scaly head armed with powerful toothed jaws. They change their skin several times, according to Gcedart amounting to ten : the extivia? retain their form so as easily to be mistaken for the larva? themselves ; the back of the head, and several of the front segments exhibiting only a longitudinal slit. The larvae, when full-grown, seek a convenient retreat, preferring the remnants of the matters upon which they have been feeding. The pupa is white, with the eyes, and several transverse markings of a brownish colour. When touched, it moves the abdo- men with considerable force; the perfect insect, ap- pears in about a month. The larva of Dermcstcxjief/i't has a tail nearly as long as the body, composed of long red hairs. The best remedy against the attacks of these insects is the employment of arsenic in the pre- paration of zoological specimens. The genus Dermestes is distinguished by having the antennae eleven-jointed, shorter than the thorax, alike in both sexes, with the last joint of the papillary palpi shorter than the maxillae. There are four or five British species, including the bacon-beetle D. lardnrius which is of a black colour, with the base of the elytra dirty ashen colour, having three small black spots. It is about a quarter of inch long, and is very common in houses, &c. D. murinus is generally found in moles, hawks, and other carrion hung up in fields or against, walh. D. vulpinus infests the hides imported by ship- loads direct from the Brazils, and so great is tho damage which it occasions, that we are informed that the sum of ten thousand pounds has been offered as a reward for its destruction. DESMANTHUS (Willdenow). A genus of aquatic herbs and shrubs found in the East and West Indies. Linna-an class and order Poll/gamut Monaecia, and natural order Leguminosts, Generic character : calyx five-toothed ; corolla with five distinct or united spatulate petals; inferior flowers apetalous ; stamens ten, rarely five ; pod evenly lengthened, and full of seeds. This genus was formerly ranked among the Mimosas, but separated by Willdenow. The terrestrial species thrive in loam and moor earth, and are propa- gated by cuttings ; the others are grown in water. DESMODIUM(Decandolle). An extensive genus of herbaceous and shrubby plants, natives of America and Asia. They belong to Diade/phia Dccandria, and to the natural order Leguniinosce. Generic cha- racter : calyx bracteate, somewhat two-lipped, the upper one cleft, the lower one in three parts ; vexil- him roundish ; keel obtuse; wings short; lomentum jointed, with intervening compressions. Tm^e plants are raised from seeds or cuttings, and are kept in stove collections. Among them we find the moving plant of Bengsl, formerly called Hrdysannn gyrnns, but now Desmodium gyrans. This plant is an annual or at most a biennial, having pinnate leaves, that is, one pair of small opposite leaflets, with an odd one of much larger size. These leaflets have a sponta- neous motion when the plant is in a high temperature, say between seventy-five and eighty degrees of Fah- renheit,, and at the same time in bright sunshine. The one slowly rises, while the other is depressed, thus alternating in position for hours together. These motions are only noticed when the plant is in the highest vigour, not being observable in very young or in very old plants. It is a phenomenon not yet satisfactorily accounted for by phytologists, but it has all the appearance in its action of that of a hydraulic machine. DESMONCUS — DIAMOND. 273 DESMONCUS (Martial). A genus of South American palms belonging to Moncecia Polyandria of Linnaeus, and to the natural order Palnue. Generic character: spatha double ; flowers sitting. Males — calyx tritid, corolla three-petaled, stamens six. Females — calyx and corolla urceolate ; stigmas three, sitting ; drupe one-seeded, shell having three pores in the shape of a star at top. This palm thrives in loam and moor earth. DEWBERRYis the vulgar name of the Rubus caBsiun, a small trailing plant found on barren ground, bearing fruit resembling those of the bramble, only much smaller. DIADEM A (Ranzani). A genus of molluscs united to the genus Coronula, of which it forms a sub- division, and is there described. DIAMOND, a mineral body of great value and hardness, first discovered in Asia. The primitive form of this precious stone is the regular octoedron, each triangular facet of which is sometimes replaced by six secondary triangles, bounded by curved lines ; so that the crystal becomes spheroidal, and then pre- sents forty-eight small facets. These two peculiar characters of the diamond are exhibited in the sub- joined figures. The diamond has been found of a great variety of colours, but those that are decidedly colourless, and those that approach to a rose tint, are most esteemed. Many stones when rubbed exhibit very distinct electrical effects, and they will attract or rep . light bodies which are brought into their neighbourhood. The diamond, when excited, exhibits positive elec- tricity ; whereas the other precious stones, if rough, afford negative electricity. In general, however, it does not retain this electricity for any considerable length of time. The diamond becomes phosphorescent when ex- posed to the rays of the sun. Many diamonds, how- ever, do not possess this property, although agreeing in colour, form, and transparency, with those which readily become luminous. The continuance of the phosphorescence varies from five or six seconds to a full hour, and this even when the stone has not been exposed more than a few seconds to the rays of the sun. It is phosphorescent under water, as well as in the air. The diamond, when exposed to the blue rays of the prism, becomes phosphorescent ; but when exposed to the red rays is not so. The spark from a charged jar produces the same effect as exposure to the sun's rays. Exposure to the light of a wax candle also produces phosphorescence. Prior to the commencement of the eighteenth cen- tury, all the diamonds employed in Europe were im- ported from the provinces of Golconda and Visapour, in Bengal, and a lew from the island of Borneo. They always occur in detached crystals in alluvial NAT. HIST. — VOL. II, soil ; and this circumstance, no doubt, tended to give currency to the fiction of the " Valky of Diamonds " in the Arabian Tales. Diamonds of any great value in a commercial point of view, were first brought from Sruth America in 1720, and we may now briefly point out the modes of discovering them both in that country and Asia. In Brazil the natives collect the disintegrated sandstone met with at the bottoms of rivers and ravines, and, by washing, separate the clayey matter from the grains of quartz and diamond. The residue is ciref'ully examined for the diamonds it may contain, which are distin- guished by their adamantine lustre, »ad regular forms. In the district of Cuddapah, in Hind istan, the mode of working the diamond mine is as follovs : — After all the superincumbent strata, and the large stones in the diamond bed, are removed out of the mine, the small gravel and other constituents of the bed are then car- ried to a short distance, and put into a cistern, about eight feet square, and three deep. In this situation water is poured upon it, which separates the lighter loamy particles. The gravel and small stones which sink to the bottom, are then thrown into a heap beside the cistern, from which they are conveyed to a smooth plane of about twenty feet square, made of hardened clay. Upon this the whole is thinly spread. The gravel in this position being slightly moistened, six or seven people go over it several times in succession. The first time they pick out only the large stones ; the second and subsequent times, the smaller gravel is carefully turned over with the flat of the hand, whilst they as carefully watch for the spark from the diamond, which distinctly marks the situation of this valuable gem. The locality of the diamond differs, however, in a geological point of view, very considerably in different parts of the world ; and, as such, the modes practised by the natives for procuring these precious gems. Thus we find that the diamond mines, as they are called, situated at Banaganpilla, are scarcely any thing more than holes in the surface of the soil. None are deeper than twenty feet, and when a gallery is excavated under the rock, it is so low that the people are obliged to work in it sitting, a mode of operating which an Indian prefers to every other. The solid rock of the hills is an agate, consisting chiefly of a coarse grey hornstone, with rounded pebbles of the same species, or of jasper. At some depth, this rock becomes a ferruginous sandstone, the grains of which are finely cemented together. Through this solid rock they are obliged to make their way before they arrive at the bed in which the diamonds are usually found. They commence at different places as their fancy leads them, with a spot about twenty feet square, which, with iron instruments and steel wedges, they break into slabs and fragments, of from one hundred to five hundred pounds weight. In this way they descend to the diamond bed, which is fifteen or twenty feet under the surface ; this bed extends round the whole hill, and is as regular in its thickness and extent as the unproductive beds in the same place : it consists of a conglomerate, composed of siliceous pebbles, quartz, calcedony, and jasper. The diamond, on account of the splendour of its lustre, its peculiar play of colour, its hardness, and lastly, its rarity, is considered as the most precious substance in the mineral kingdom, and is particularly valued by jewellers. The diamonds purchased by jewellers are generally in grains or crystals, and some- S '274 DIANCHORA— D1ANTHUS. times coarsely polished. It is also used in the form of a powder by lapidaries, for cutting and engraving upon harder gems ; by watchmakers in their jewelled timekeepers ; and by glaziers for cutting glass. The diamonds chosen for cutting glass are all crystallised. The faces are curved, and hence the meeting of any two of them presents a curvilinear edge. If the dia- mond be so placed that the line of the intended cut is a tangent to this edge near its extremity, and if the two surfaces of the diamond laterally adjacent, be equally inclined to the surface of the glass, then the conditions necessary for effecting the cut are complied with. In addition to the cutting and engraving of glass, the diamond has been very advantageously em- ployed in drawing minute lines on the surface of steel, by which all the beautifully variegated tints of the rainbow may be produced. The largest known diamond is probably that men- tioned by Tavernier, originally in the possession of the Great Mogul. Its size is about that of half an hen's egg : it is cut in the rose form, and, when rough, is said to have weighed nine hundred carats. Among the crown jewels of Russia is a magnificent diamond, weighing J95 carats. It is the size of a small pigeon's egg, and was formerly the eye of a Brahminical idol, whence it was purloined by a French soldier ; it passed through several hands, and was ultimately purchased by the empress Catherine for a sum equal to about one hundred thousand pounds sterling. There is only one other diamond which our space will permit us to notice. This is the celebrated " Pitt diamond." It was brought from India by an English gentleman of that name, who sold it to the regent duke of Orleans, by whom it was placed among the crown jewels of France. It weighs rather more than 136 carats, and was purchased for one hundred thou- sand pounds. This country is not celebrated for the size of the jewels which adorn the regalia of the sove- reign ; but there are some beautiful models in the British museum of those we have described. For an account of the chemical constituents of the diamond, see the First Division of this work. DIANCHORA (Sowerby). A fossil species of shell, the animal of which is consequently unknown. The shell is thin, adherent, regular, symmetrical, equi- lateral, subauriculated, inequivalve, one valve hollow within, and convex externally ; the other flat, articu- lated by two very distant condyles. It belongs to the order Palliobranchiata. DIANELLA (Ker.) A genus of tuberous rooted herbs, indigenous to New Holland. Linnsean class and order, Hexandria Monogynia, and natural order AsphodelccE. Generic character : corolla rotate, regu- lar, six-parted, and deciduous; stamens below the germen, filaments bent, and thick at the top ; anthers linear and erect ; style filiform ; stigma simple ; berry globular, and many-seeded. These plants grow well in sandy loam, and are increased by dividing the roots. DIANTHUS (Linnauis). A very numerous and beautiful tribe of herbs, much esteemed for the ele- gance of their flowers and for their fine scent. Lin- naean class and order, Dccandria Digynia, and natural order Caryophyllece. The pink, clove, carnation, and sweet- William are all well-known favourites, and met with in every flower-garden ; and some of the florist's varieties are highly valued and sold at high prices. Carnations and pinks receive the greatest attention and care from the florist ; the former is the Dianthus Caryophyllus of botanists, and the improved variety of the clove of florists. It ranks as the chief of stage flowers, as it combines elegance of form with variety and delicacy of colours, and to these is added the most delightful fragrance. To have flowers in the greatest perfection, new plants must be raised every year ; not but that old plants will continue to yield flowers for several years ; but these being those of branches, are never so large or so fine as such as are produced on the central stem of a maiden plant. Young plants are obtained by layering the lower branches of the last year's layers ; and though these be only the points of the secondary shoots, yet when separated from the parent stock, they become, as inde- pendent beings, ten times more vigorous and ampli- fied than if they remained on their original roots. The cultivation of choice carnations forms a prin- cipal part of the florist's business. They are usually named, and the superior sorts, especially if they are new, sell at high prices. New varieties are obtained from seed ; but very fine stage or prize-flowers occur but as one in a thousand interiors. A seedling of pro- mising merit, may, by judicious culture, be advanced to rank with the best : and it is by accident, and such means, that our present stock of (hie carnations has been in course of time obtained. The standard choice sorts are perpetuated by annual layering. This is performed about the time or soon after the plants are in flower ; but if layered before, or as soon as the shoots are ready, the better. If cultivated as stage flowers, they are kept in pots, and of a pretty large size, in order that their branches may be conveniently layered. If cultivated iu beds, there they are also layered ; because there must be an annual supply of young plants as well for beds as for pots. Carnations are layered like other plants ; the lower branches, which would not flower till the following year (supposing them to be left on the parent stool), are chosen ; an incision is made with a keen pen-knit'e entered a little below the tjiird or fourth joint from the top, and passed up the middle of the shoot as far as the next joint. This separated piece is called the tongue, and when the little piece below the bottom joint is cut square off, it is ready to be fixed in the soil. In layering, a little fresh compost is usually laid round the plant to receive the layers. In this," little furrows are made, and in which that part of the layer between the tongue and the root is bent down and firmly fixed by a little hooked stick. The layer is then covered with about three-quarters of an inch of the compost ; and at the same time the point of the layer is gently raised upright, taking care that the tongue be kept apart from the place whence it was cut, and pressing the soil pretty closely over, and around the point of the layer to keep it in place. New roots are soon produced at the lower end of the tongue, and towards the end of September are fit to be taken from the stools and planted in beds or pots previously prepared for them. Some florists are very curious in forming their car- nation compost j mixing together many different sub- stances, as loam, sand, leaf-mould, and rotten dung of various kinds. Such a compost may be very suitable, but many successful cultivators use only the freshest maiden loam, made sufficiently rich and porous by a third part of thoroughly decomposed stable or old hot-bed dung. In this, carnations, whether in pots or in beds, thrive and flower in the highest perfection, provided they receive all other necessary treatment. D I A P E R i D M — D I C E 11 M A. 275 The management of carnations consists not only in placing the layers in suitable soil, but in taking care that if potted, the pots be well drained, so that water rnay not stagnate within, which would materially check the growth and spoil the beauty of the flowers. Water must be always supplied moderately, and without excess of either moisture or dryness. The layers when taken off the stools are first placed in small-sized pots, and usually shifted twice into larger, before they are brought to flower. The most perfect cleanliness, keeping free from weeds, and defending against snails, slugs, ear-wigs, and wood-lice, are all indispensable, through the whole course of their growth. When the stems are advancing to flower they are often attacked by the green-fly or aphides ; these must be banished by tobacco-smoke, or some other means not hurtful to the plants. Props must also be timely fixed to tie the sterns to, as they advance in height ; and as several flower-pods will appear on the same stem, all but the topmost, or the two topmost, should be cutoff; this is for the purpose of encouraging the principal flowers to bloom in greater beauty and amplitude. In order to assist the flowers to expand regularly and handsomely, florists exercise certain manipula- tions which are exclusively their own ; these are called hooping and carding. The calyx or flower-cup is liable to burst irregularly, that is, it will be rent lower down on one side than on the other ; to pre- vent this, two expedients are practised : the first is causing the divisions of the flower-cup to open equally by assisting the backward ones with the point of a penknife ; and the second is by hooping, that is, by fixing a band of matting or soft string round the middle of the flower-pod, by which means the divi- sions of the calyx are made to burst regularly. These precautions regulate the bursting of the calyx ; and in order that the corolla, or coloured petals of the flower may be expanded laterally and symmetrically, circular cards (having a hole in the centre to embrace the calyx) are fitted on immediately behind the spreading petals of the corolla, the card acting as a support to the petals, which naturally incline to fall back. By these means the petals are exhibited in a plane ; besides which every tint and form are seen to the best advantage, and when so dressed up by the skill of the professional florist, are certainly objects of great beauty. These practices are only followed by flower-fanciers who exhibit their flowers at shows for prizes, and at which there is sometimes the most intense and lively competition. Pinks receive nearly the same treatment as carna- tions, only instead of being layered, they are propa- gated by cuttings, technically called " pipings." This is usually performed in June or July, or as soon as the best sorts can be ascertained by view of their flowers. See article PINK. The annual sorts of Dianthus are raised from seed ; and all the other species and varieties may be propa- gated by layers or cuttings without difficulty. DIAPERIDJ2. A family of coleopterous insects belonging to the section Heteromera, and sub-section Taxicorncs of Latreille ; the head is disengaged from the anterior margin of the thorax, which is either square or cylindric, and, as well as the elytra, not dilated into a flattened margin, as in the Cossyphidee. Latreille places in this family the Phaleriae, and some other genera which appear to belong to the family E, in which family, indeed, the whole of the present group is arranged by Mr. Stephens, whilst Mr. Curtis considers the Diaperidce as nearly allied to the Hclopidce; the perfoliated or serrated antennae, which are never monili form .will well distinguish them. The other genera are Uloma, Diaperis, HypophUeus, Trncliyscclis, Coxclitx, and Eledona (Boletophagits, Fabricius). The family is not extensive, as regards the number of species, some of which are elegantly marked and coloured, in which respect thev certainly approach the Helojrida:. The species are of small size, and are, for the most part, found in fungi, Boleti, under the bark of decaying trees, &c. The typical gennsDia- pem.Geoftroy.is distinguished by the antennae.of which the three basal joints are slender, the remainder broad, transverse, and distant from each other. The type of the genus is the Chrysomela boleti of Linnaeus, of a rounded form, and black colour, having the base and extremity of the elytra, as well as a central interrupted fascia, orange-coloured. DI APHORA (Stephens ; CYCNIA, Hiibner. Steph.) A genus of lepidopterous insects, belonging to the family ArctadcB, and consisting of a single species, the Bombyx mendica of Linnaeus, having the wings short, and clothed with but few scales, whence the English name of the moth (spotted muslin) ; the palpi have the terminal joint slender and obtuse. The name of the genus alludes to the great diversity between the sexes of this moth, the male being of an ashy brown colour, whereas the female is white, with black spots. It is about an inch and a half in expanse. We have already on several occasions noticed the occasional periodical delay which takes place in the development of insects, and this moth offers a still more curious instance, it being recorded by Marsham, that out of thirty-six caterpillars hatched from a brood of eggs, all of which fed together and spun their cocoons at the same period, twelve only appeared at the usual season ; twelve more were produced the following year, and the remaining twelve the third season, as perfect and healthy as those produced at the first. The moth is not uncommon in marshy districts near London, appearing at the middle of May. DIAPRIA (Jurine). A genus of minute hymen- opterous insects belonging to the family Proctntru- pidte, and distinguished by the beautiful antennae of the males, which have the joints globular and con- nected together by slender articulations and orna- mented with whorls of hairs. They are found in grass, upon trees, &c., and are supposed to be para- sitical upon other insects. DIAZOMA (Savigny). A genus of molluscs united to the genus Botryllus. DICERAS (Lamarck). A fossil genus of mol- luscs, approximating to the genus Chama, from which, however, it differs by being regular, equivalve, never attached by the lower valve, and the distinct character of the hinge. DICERATA. The second family of the second order Polybranchiata. Second class Paracej)halophi>ra. The general characters of these molluscs is their possessing two tentacular retractile appendages placed on the upper part of the body in a kind of sheath, situated at their base ; a membranous wing or sail, more or less extended above the mouth, the organs of respiration in the form of little branches, exter- nally placed. DICERMA (Decandolle). A genus of under- shrubs, indigenous to India. Elegant diadelphous plants, formerly called Zornia and Hedysurum, by S2 276 DICHELESTIUM — DIDELP II US. Linnaeus, Lilt since new named as above. They are easy of management and propagation, like other stove plants. DICHELESTIUM (Hermann). A curious genus of parasitic, entomostracous, crustaceous ani- mals, belonging to the order PaEcihpoda, and section Siphonostoma, having the body long and narrow, com- posed of seven segments, the first of which is larger than the rest, with a pair of slender filiform antenna;, a pair of short didactyle claws, a tubular sucker, three kinds of feelers, four short legs for prehension, termi- nated by several toothed hooks ; the second and third segments are lunate in form and furnished with very short legs ; the sixth segment is long and somewhat cylindric, and the last small and oval. The animal of which this genus is composed is rather more than half an inch long, and insinuates itself into the flesh and the gills of the sturgeon, as many as a dozen having been found upon one fish. Of this number three of the specimens were one-third smaller than the others, with the body curved : one of them lived three days when removed from the fish. They are enabled to retain firm hold of their prey by means of their strong frontal pincers. DICHLAMYDE^E, a subdivision of dicotyledo- nous plants, including those which have a double floral covering, or both a calyx and corolla. The greater part of the handsome flowering trees and shrubs are found in this division. DICHONDRA (Forster). A genus of evergreen creepers, natives of the West Indies. Linnsean class and order, Pentandria Digynia, and natural order Convolvulaceiz. This succeeds well with ordinary stove management, and may be increased by cuttings. DICKSONIA (Heretier). A genus of exotic ferns, so named in honour of James Dickson, a British cryptogamist of great abilities and unwearied indus- try. It belongs to the order FiKces, and one of the species is a tree fern from St. Helena. DICLIPTERA (Vahl). A genus of tropical plants, mostly under shrubs, belonging to the class Diandria, and to the natural order Acanthacece. Gene- ric character : calyx bracteate in four or five divisions ; corolla two-lipped, the lowest nearly entire ; anthers two-celled ; capsule roundish, nearly one-celled, dis- sepiment ultimately free, to whicn the seeds are attached. This genus is nearly allied to Justicia, but differs in the structure of the capsule. It thrives in rich light soil, and is propagated by cuttings. DICLYTRA (Borckhausen). A diadelphous genus of plants found in the north of Asia and America, and belonging to the natural order Fuma- riaceas. Some of the species were at first called Fumaria, and others Corydalis ; but these, together with five others, are now known by the name first above given. DICOTYLEDONES, or EXOGEN^E, a divi- sion of vascular, flowering, or phaenogamic plants, in which the vessels are arranged in concentric layers, the youngest of which are external, and the cotyle- dons of the embryo are opposite or verticillate : the dicotyledonous plants have a more or less conical trunk, consisting of bark, wood, and pith ; the wood being contained between the other two. The thick- ness of the trunk is increased by an addition of new matter between the wood and bark. They have reticulated leaves which are distinctly articulated with the stem. The veins of the leaves are much branched ; the flowers have generally a double perianth (dichla- mvdeous), and frequently exhibit a quinary divisiua The embryo is furnished with two cotyledons (hence the term dicotyledonous), which after germination, frequently assume the appearance of leaves. By these characters the plants of this division are distin- guished from those of the monocotyledonous class. DICTAMNUS (Linnaeus). Hardy ornamental herbaceous plants, said to be natives of Crete, but long cultivated in this country under the name of Fraxinella. The flowers are decandrious, and accord in character with those of the natural order Rutaccce. There are two species, both of which grow any where, and are raised from seeds. Dictamnus is also a specific name of an origanum (marjoram), commonly called Dittany of Crete. DICTYOPTERA (Leach). The family of the cock-roaches (Blattidee], on account of the flattened oval form of the body, the five-jointed tarsi, and several other less important characters, was considered by Dr. Leach as sufficiently distinguished from the other orthopterous insects to warrant its separation as a distinct order, to which he applied this name. His arrangement has not, however, been followed in this respect. See BLATTA. DIDELPHUS — Opossum. A genus of marsupial, or pouched animals, inhabiting the American conti- nent, and the first animals of this singular order which are known to naturalists. Their generic characters are ten incisive teeth in the upper jaw, and eight in the under, the intermediate ones in the upper jaw being longer than the rest ; the three front grinders compressed, and the last four tuberculated ; those above triangular, but the under ones oblong, and two canines in each jaw, making in all fifty teeth, which is a greater number than is possessed by quadrupeds of any other genus. Their gape is wide, and the appearance of the mouth ragged ; but their bite is feeble, compared with the size of their biting appa- ratus. Their tongues are beset with horny tubercles, like those on the tongue of a cat ; and their tail is in part naked on the under side, and prehensile. Their ears are large and naked, and their aspect is alto- gether very peculiar. Their hind feet have the thumb or fifth toe long, and capable of acting in opposition to the other four, so as to lay hold like a hand. The four toes which act together on the hind feet are fur- nished with nails ; and when not used in grasping, the nailless one is turned to the rear, like the hind toe of a bird. Their legs are short in proportion to the size of their bodies ; they plant their feet upon the round pad of the sole when they walk, and their rate of motion on the ground is but slow. In trees, however, which the greater number of them chiefly inhabit, they have much power of themselves, and climb and hold on with much address. Their eyes have the irides yellow, and the pupils are vertical, like those of the fox. It has been said of them that they have a gape like a pike, the ears of a bat, the feet of an ape, and the tail of a serpent ; and, cer- tainly, taking their characters all in all, they differ very much from the placental mammalia. The diffe- rence extends not only to the form of the body, and the structure of those parts upon which the classifi- cation is founded, but it extends to the very covering, the hair of the opossum being unlike that of most other animals. It is neither sleek nor frizzled ; and it has more resemblance to whalebone than to common hair, and on the naked parts there are sometimes scales. This uncouth sort of covering the seini- DIDELPHUS. 277 transparent ears, which appear reddish when seen against the light, the yellow sinister eyes, the short legs, and the singularly formed feet, give these ani- mals a repulsive appearance, which is in no wise diminished by the very fetid and offensive odour which they give out. The different species vary considerably in their habits ; but they may be gene- rally described as nocturnal animals, the principal part of which inhabit trees, in the holes of which they lodge ; and they prey upon birds, lizards, and other small animals. Some of them also haunt the margins of the waters and feed upon shelled mollusca and Crustacea. All the species have the general characters of mar- >9upial animals, the most remarkable of which in the skeleton are the two marsupial bones attached to the pubis, which support the pouch. The whole of the opossums have not, however, a distinct and produced pouch, into which the young can be received, and, therefore, there are some distinctions between them in the economy of their gestation, which can be more fully explained when we come to mention the species. We shall have occasion to notice the general subject when we come to the article MARSCPIATA ; and, therefore, we shall in the mean time confine ourselves chiefly to the popular description of the species. They are, as we have said, all nocturnal animals ; and they are all carnivorous ; but they do not possess the same degree of power and energy as the carni- vorous animals, properly so called ; and they are remarkable for stupidity, or at all events they do not display the same cunning as the fox, though their eyes resemble those of that animal. The habit is different, however ; for the opossums, generally speaking, seek their prey in trees, whereas the fox is an animal which, though fond of brakes and other cover, is in- capable of climbing. The form of their hind feet enables them to lay hold of a branch, and retain that hold, while they have perfect a command of the head and anterior extremities for other purposes. Thus they can make use of the crooked claws with which their fore-feet are armed, to help them in the capture of their prey. At settlements near the woods, where they are plentiful, these animals are sometimes apt to play the weasel in poultry yards ; and, like that animal, they suck the blood of their victims. It is not a little singular that marsupial animals should be found in two zones of the earth, which lie nearly on opposite meridians, the centre of the one about 120° east, and the other about 60° west of the meridian of London ; and that in all the districts between them there should be no animal of this cha- racter, or even approaching to it. What stage ol the geological duration of countries may answer to animals of this singular order, it is not easy to say for, though we admit that a few specimens have been found fossil in our own latitudes, it is impossible fo us thence to conclude that the animals belong either to an early or a late stage of the country ; for we have them in the rich woods of South America, ane in the comparatively barren extent of New Holland while there are none in Southern Africa, which is inter mediate between these, and partakes of the characters of both. We shall now briefly enumerate the species ; anc .first those in which the female is furnished with a dis- tinct abdominal pouch for the reception of her young during a portion of the period of ger-tation, and as a place of safety occasionally till they are able to shift or themselves. Of these there are three tolerably veil established. THE VIRGINIAN OPOSSUM — Didelphus Virgimana. This species is by far the best known, at least to the people of this country, from its abundance in the southern parts of the United States. But as it is very generally distributed over America as far as the bor- ders of Patagonia, or at all events to the margins of the Pampas, the name Virginian is by no means de- scriptive of it: indeed there is nothing tends more to confuse the nomenclature of natural history, than the naming of natural productions, whether animal or vegetable, after places, or after individuals of the human race. The first method ties the production down to the place named ; and though there may be no great harm in naming a particular breed of cattle, sheep, or pigs, after the place which is most famed for their production, yet in cases like the one under notice, it is very absurd, — the Virginian opossum being found over a range in latitude of certainly not less than five thousand miles, while the individuals are far more numerous in South America than -in North, if the whole surface of each be taken. The usual size of the opossum is the same as that of a cat ; its covering consists of a mixture of black and white hairs, with the ears having the one part black and the other white. The head often entirely white. It is very generally distributed, inhabits the woods, is not timid in the vicinity of settled places, prowls about in the night, killing poultry, sucking eggs, and committing other little depredations ; but we need hardly add that, to man, it is quite harm- less. The young, which are often as many as seven in number, are exceedingly light and small, at the time of their birth, that is, the time of their first birth, when transferred from the internal uterus to the pouch. The gestation in the uterus lasts twenty-six days, at the end of which the young have no vestiges of eyes or of ears, and are, indeed, little else than small lumps of gelatinous matter. They do not open their eyes till about the fiftieth day ; but they readily find out the teats in the pouch, and attaching themselves to these, they increase in size. They remain in the pouch, or at feast resort to it occasionally as a place of safety, until they are grown to about the size of rats. The Virginian opossum, extending as it does over so vast a range in latitude, is subject to much variation of colour. There is also considerable difference between the appearance of the young ones and those which have arrived at perfect maturity. The body of the young animal is generally of a yellowish-grey, mixed with some hairs entirely white, and others entirely black ; the last of which are most abundant along the back, and give that part of the animal the appearance of being marked with a dorsal line. A band of a similar colour descends from each side of the neck to the fore-legs ; these legs and also the hind ones are covered with black hairs, and the tail is covered with scales, with a few short and weak hairs thinly interspersed. The hands, that is the prehensile parts of the hind feet, the ears, and the point of the muzzle are naked. The skin on the soles of the fret is violet black ; but the toes and nails are flesh- coloured. The whiskers, which appear to be used as instruments of touch, as is the case with all mamma- lia which seek their prey by night ; and it is pre- sumed also, that the toes, which have a very delicate covering, are highly sensitive. The eyes are small, without any external lids, and are remarkable for their convexity and consequent projection jcyond their 276 DIDELPHUS. sockets ; and from this peculiar structure of the eye, it is probable that the animal sees only at short dis- tances, but that its vision there is quite microscopic. Virginian oppossum. From the structure of the nose it is presumed that the sense of smell is very acute ; but it cannot be very delicate in our way of estimating ; for in that case the animal would be perfectly intolerable to itself, the odour which it emits when disturbed or threatened being described as one of the most offensive in nature. But there is no subject upon which we are more in the dark, and more likely to remain so, than that of the senses of animals. We know the operations of our own senses very imperfectly ; and in the case of smelling in particular, we are unable to say what is the specific difference of affection in our organs, which makes us turn with feelings of pleasure to the odour of roses or of new hay, and shun with pain and aversion that of such an animal as the opossum. Now, if we know little of these matters in our own case, where the pleasure is mental, and, whether we understand its foundation or not, a result of reason and experience, and given us as one of the means by which we are to understand the properties of things, and apply them to our uses in the most pleasing, and at the same time, in the most economical manner for the good of the whole ; — if we are thus ignorant in our own case, where we have something of more im- portance than the mere animal sensation to guide us, what can we know in the cases of the other animals ? and not knowing, how can we reason ? Still, this is a subject upon which it is exceedingly difficult for any body to refrain from speculating, and it is nearly, if not altogether, as impossible for any body to be right in such speculations. We are, however, thus far certain, that no animal can feel what we call mental pleasure from sensation, apart from the office which that sensation may supply in the mere economy of the animal. Thus, for instance, there is no material eye, except that of man, which can see beauty in form or in colour, neither is there any nos- tril, save his, which can scent fragrance, and derive from it those emotions of delight, which we never fail to experience when the healthful breezes come to us sporting over beds of flowers. But, if we cannot sup* pose animals have the pleasures of sense, which are mental or supplemental to the mere excitement of the bodily organs, we cannot suppose that they should have the opposite feeling of deformity to the eye, and ungrateful odour to the nose. Upon this principle we can readily perceive that, offensive as the smell of the opossum is to our feelings, it may itself be alto- gether insensible to that odour which instinct teaches it to give out, probably as its chief means of defence. In many parts of South America the opossum is so abundant, that it prowls about in the villages, and even in the towns. D'Azzara mentions that they are frequently found lying dead iu the villages near the shores of La Plata, and even in the streets of Monte Video. He was the first to get a correct account of the marsupial apparatus of the female, which we shall give in nearly his own words. " The female has the whole length of the belly cleft or slit, and appearing like a person's waistcoat buttoned only at the top and bottom. This cavity the animal has the power of firmly closing. Within it are thirteen teats, ex- tremely small, one in the centre, and the rest ranged round it." Before the female comes to maturity, this marsupial apparatus is but little developed, there being only a slight fold of skin on each side the abdomen. Alter the young are weaned, the marsupium also collapses, and it is gradually reproduced as the time approaches when it is to receive a new litter. There seems indeed to be, so to speak, an alternation of the t\vo systems of gestation in these curious females. The uterus is the place where impregnation is effected, and where the germ is developed, at ieast in its early stage ; but as this takes place when they are in a much more rudimental state than any young animals which pass at once from the uterus to an external mammary system, there is a degree of excitement required in the marsupial apparatus which is not needed in the case of those animals which produce their young comparatively mature, and capable of taking the teat at intervals as nature requires. The perfect marsupial animals, or those which have the internal and external periods of gestation pretty nearly of the same length, remain on the teat, like any moveable excrescence, until they are completely developed ; and it has been ascertained, that in some of the species at least, there is a sort of umbilical cord which connects the young with a sort of placental substance in the body of the teat, until it acquires its form and some of its functions as an animal, at which time it breaks this second connection with the mother, or is born a second time, now an independent animal, capable of drawing milk from the teat, and in due time of finding its food. But this second gestation in the marsupium is clearly as essential to the perfect development of the animal as the first gestation in the internal uterus ; and we can no more imagine an opossum to come to maturity, if it enjoys only the first, and has not its full time in the second, than we can imagine the untimely birth of any other animal to become mature. This is a most extraordinary piece of nature's economy, and a part, the design of which we are unable, in the present state of our knowledge, to comprehend, and yet it is one which very powerfully and pressingly tempts us onward to inquire. Now, we perceive that this double gestation, by means of the internal uterus and the abdominal pouch, stands as it were midway between the single internal DIDELPHUS. -270 gestation of the ordinary mammalia and the internal elaboration of the egg, and external, and we may say unconnected evolution of the chick, by the process of incubation, in birds. The common mammalia require the interim! warmth, protection, and action of the mother, with perfect exclusion of the atmosphere from contact with the body during the whole time that the fetus is coming into form. The bird requires that the egg shall be matured in the ovary and oviduct of the mother ; but when this is once accomplished, the connection, that is, the material connection, as conveying substance from the one to the other, is cut off for ever as between the parent bird and the future chick, which is still a formless embryo in the egg ; so that the egg may be hatched, for the evolve- mcnt of all the necessary membranes and vessels, and the chick itself may be brought forward by the heat of another bird, or by any heat, if properly applied. We have therefore a second life, as it were, in the young bird, in the action of which the parent bird has no necessary concern ; and, if placed in favourable circumstances, by the exclusion of atmospheric air and the light, we know not for what length of time the egg of a bird might not be preserved with the prin- ciple of life within it, ready to be called into action by the necessary stimuli, and capable of restoring the species again to the world, even though, by any catas- trophe, all the ancestors of the egg were swept away. It is not so, however, with mammalia, for they would necessarily perish, not only with the individual, but with any circumstance which might affect the internal health of the mother during the period of gestation. The marsupial animal is intermediate between these ; and we may reasonably suppose, that as the second stage of its progress in organisation takes place externally of the mother, and partially exposed to the atmosphere, we may very naturally conclude that this marsupial foetus, being in less intimate con- nexion with the system of its mother than an uterine one, must not be so subject to suffer with the suffer- ings of her system, but that the mother, with the young in the marsupium, must be able to undergo greater privations, and bear greater hardships, than the uterine mother. We know, also, from the observed fact, that a marsupial mother can bring forward not only two, but perhaps three successions of progeny at the same time. There have been found some in the internal matrix, and some others in the marsupium, so differing in size and development, that they must have been the products of separate impreg- nations. No doubt, we have cases of superfcetation among uterine animals, as, for instance, in the common hare, but the authenticated ones are very few in number ; they are probably all referrible to the category of " monstrosities of habit'' which take place in animals, as well as monstrosities of form ; and, at all events, they form the exception, and the rare exception— not. the rule. During marsupial gestation, on the other hand, reimpregnation is so common, as to be the rule, and not the exception ; and it accords with the economy of nature that such should be the case. There is, therefore, evidently an absolvernent of the system of the marsupial female from what would be called the labour of maturing the succession, at that very time when this labour falls most heavily upon the uterine mother, and renders her more helpless than at any other state of her mature and undecayed existence. Hence we see that the marsupial animal is fitted for contending with, and triumphing over, hardships which the common mammalia eouSd not so well endure ; and if, having found this power in the animals, we can discover a corresponding occupation for this power in the countries where such ai.inuds are found, or in the situations in which they have to preserve their lives and find their livings, then we are in possession of two elements which will enable us to approach at least to the outworks of this the most impregnable point in the whole physiology of ani- mated nature. Now, it will not fail to occur to every reader, who has the slightest general acquaintance with the economy and relative distribution of productions on the surface of our earth, that the three grand localities, or, strictly speaking, the two only, for New Holland and the Oriental Isles, and south-eastern peninsula of Asia, may be considered as one great district, which is cut off from much migration of land-animals by the intervening seas, but over which birds migrate with the changing monsoons in numbers, which to us, lying as we do at the outskirts even of the migration of Europe, Western Asia, and Africa, would be perfectly incredible, if we did not know the fact from the most undoubted authority ; it will readily be seen, that this tract, and also the eastern side of America, which, from the great cordillera of the Andes running near the west coast, comprises by far the greater part of the continent, are countries beyond all others stocked with tree birds ; and not only this, but that, generally speaking, quadrupeds, with the exception of these animals, are few, and of only trifling dimen- sions. Australia, which, from the dryness of its surface at one season, and the torrents in which rain falls at others, may be regarded as having the extreme character of this species of country ; and the qua- drupeds there, with a few very trifling exceptions, are all marsupial, whether they feed on animal matter or on vegetable, and whether their chief prey be sought on trees or on the ground. In South America the character is less extreme, but still it is not less of a tree-bird country than any part of the East, at least in those regions which are covered, as much of it is covered, with extensive and luxuriant forests. The changes of season are very great in all those countries ; and therefore, the labour which the animals have in finding their food is sufficient to account for the absolvement of the females from that portion of systematic labour in bringing their young to maturity which we have seen that they enjoy. This is not the place for entering fully into the question ; but as all the principal genera of marsupial animals occur in the order of the alphabet before the general article MARSUPIATA, we shall collect the leading points of the evidence in the particular articles, which will enable us to sum them up more briefly, and with a better chance of being understood, than if we brought a question so curious and so complicated into one article. We shall therefore now resume our notices of the species Didelphus. The CRAB-EATING OPOSSUM — Didelphus Cancrivora, This animal has more the figure of a rat than the former. Its forehead is nearly straight, and its muzzle much pointed. The general colour of the head is white, with a few scattered bristly hairs, as whisker?, on the upper lip and on the posterior part of the cheek, and one or two over each eye ; the eyes and ears are also black, which form a striking contrast with the general white colour of the face and head. The ground colour on the neck, the back, and sides, is yellowish, sprinkled or grizzled with black and 280 DIDELPHUS. white, the black hairs being shorter than the yellowish, and the white ones longer, but with a portion of black at the points. These long hairs form a sort of line along the back, and when the animal is excited, it has the power of erecting them. The legs and feet are wholly black, with the exception of the last joint and the claws, which are white ; the tail, which is covered with scales and very short hair, is black at the base, and white for more than two-thirds of its length toward the tip. It is tapering to the end, and prehensile. Crab-eating opossum This animal is remarkably low upon the legs. Its whole length is about thirteen inches, exclusive of the tail, and its height not above six inches, while, from its applying the whole length of the hind feet to the ground, and having the fore ones short and crooked, it is much lower at the shoulders and the crupper than at the middle of the back. It has been observed principally on the warm shores of South America, where it resides in the holes of the rocks above water, and seeks its food chiefly off crabs and other crustaceous animals. Its hind feet are well adapted for grasping, like hands, and its fore paws, which have sharpened crooked claws, and the toes much divided, are also good prehensile instruments ; but, in addition to these, it is said to render its tail available, by thrusting it into the holes which the crabs inhabit, and drawing them forth to their destruction. The FOUR-EYED OPOSSUM — Didelphns Opossum, is the only other known species which has the nmrsupium fully developed. Like the former, it is an inhabitant of the warmer shores of South America, but it is a more inland animal, and its food is different. It is rather smaller than either of the former, being about a foot in length, with the tail about one foot two inches. Its head is pointed, the whole of the profile forming a straight line. The ears are large, round in their form, and very thin in their substance. The prevailing colour in the upper part is reddish brown, mixed with grey on the back, but purer on the head. On this dark colour there are placed two circular spots of white in front of the ears, and it it from these two spots that the animal gets the name of four-eyed, just as some breeds of dogs in this country get the same appellation from two brown spots on a black ground immediately over the eyes. The under part is dull white ; a small portion at the root of the tail is covered with the same hair as the upper part of the animal, while the remaining part of that organ is nearly naked and scaly. The female has six or seven teats in the pouch, and in these animals there is a different arrangement from the teats of common mammalia ; in them they are arranged in pairs right and left, while in these marsupial animals there is one central, and the others surrounding. The Opossumt which have no pouch inclosing and concealing the teats, are smaller than those in which the females are furnished with that appendage ; but, though the teats are exposed, the young are placed upon them, and adhere and grow there in a manner not very different from those which are enclosed in the pouch ; and the abdomen is supported by marsupial bones in a similar manner. This circum- stance shows that the pouch, that is, the external duplicature of the pouch, is not the essential part, but merely a protecting membrane ; for it does not appear that the species that are without it carry their young with more difficulty than the others. The MEXICAN OPOSSUM, or CAYOPOHN — Didelphui dorsigera. This species is about seven inches and a quarter in length ; the eyes and surrounding spaces are brown, there is a line of the same colour up the middle of the face, and the sides of the head are brownish ash. All the upper part of the body is greyish yel- low, and the under side yellowish ; the ears are surrounded with yellow at the base, and the tail is spotted with brown and yellow, having a part near the insertion covered with hair, and the remainder naked and scaly. This is the species which is described under the name of the slender -tailed opossum by some naturalists. The MARMOT OPOSSUM — Didelphus murina. This species is less than the larger of European rats. — It is the marine opossum of Pennant and Shaw ; and though smaller in size, it does not differ greatly in its general appearance from the species just mentioned. The muzzle is rather more pointed, the ears rounder, and the head more convex ; the eyes are situated in the middle of a transverse band of black, which is broader above than under their openings, and does not extend far beyond their openings laterally. — The upper part of the body is a mixture of fawn and ash colour, the under part is whitish, but with a mix- ture of fawn which is gradually less and less con- spicuous as it approaches the central part of the abdomen. These little animals are, however, subject to very considerable variations in the colour of their attire ; and they have, on this account, sometimes been described under different names. The females are furnished with about fifteen teats, situated among the folds of skin in the groins ; and the young ones, after they are discharged from the uterus, adhere firmly to these, like little round buttons, until they acquire the developed form of organised animals. The power of adhering to the mother is very wonderful in all the marsupial animals, but more especially in those which are not provided with a developed pouch ; and after they have acquired some form, and are detached from DIDERMUM — DILLENIACE^E. 281 their permanent connection with the teats, these little animals may be observed holding on by the sides and legs of their mother, with a firmness that would »ot be expected in creatures which are apparently so small and so helpless. The species now under notice are inhabitants of the woods, in which they prey upon very small animals ; and the mother may be seen with ten or a dozen little ones, riding on her sides or back, and she holding them on with her prehensile tail while she moves from branch to branch. The THICK-TAILED OPOSSUM— Didclpfnts macroura. This is a species considerably larger than the former, and though it has hitherto been described as a native of Paraguay, it is probable that, like the rest, it may be pretty generally distributed over the warmer parts of America. It. is larger than the species last described, being about eleven inches in length. The tail is very thick for so small an animal, being not less than three inches in girth at the root. It is covered with hair of smooth texture for the first third, and the remain- ing two-thirds towards the tip are scaly, and it is all black, except an inch and a half at the point, which is of a white colour The upper part of the body, the under part of the head, and round the eyes, are bright cinnamon brown ; the face and the feet are of the same colour, but deeper. The cinnamon colour in the female is brighter than that in the males. The teats of the female are contained in an elliptic fold, and there are frequently more on one side than on the other. This species is said to be a little more ener- getic in its characters than some of the rest of the genus ; but its manners, like those of most of the others, are imperfectly understood. SHORT-TAILED OPOSSUM — Didelphus brachyura. This is a very small species, not exceeding five or six inches in length, and with the tail only about two inches and a half. It is understood to be that which is described by Buffon under the title of the Touan. The upper part of the body is blackish ; the cheeks, hroat, flanks, and inside of the thighs and paws are iright red ; and the centre of the under part pure .vhite. The female has not fewer than fourteen teats situated in the folds of the groin, which are absorbed when she ceases to suckle. The odour which the male emits, when irritated, is described as being very un- pleasant. In some parts of the country these animals live in holes of the ground, which they dig for them- selves, but in other situations where the surface is dif- ferent, and there are hollow trees, they burrow in these. Delphinus pusilln. This species, though named by authors, and particularly described by D'Azzara as his No. 6 of these curious animals, is not so clearly established as most of the others. It is described as being about seven inches in length, exclusive of the tail, the last three inches of which part is naked and prehensile. A circle round the eyes is black, with white markings of the eye-brows, separated by a triangular spot of a dusky hue. The general colour of the body is that of the shrew, or a sort of dark mouse colour ; it is described as inhabiting near the dwellings of the Indians in Paraguay, and throughout the greater part of the valley of La Plata, and having many of the characters of a common field-rat or mouse, at the same time that it retains the marsupial structure and charac- ters, and the general appearance of the rest of the genus. Such is a brief outline of most of the particulars which are known respecting the appearances, habits, and localities of this genus generally, and also respect- ing the individual species of which it is made up. In an economical point of view they arc animals of small value, though the foetid odour of the living animal does not extend to the flesh, which is eaten by the Indians ; but in a natural history point of view, they are far more interesting and important. DIDERMUM (Savigny). A genus of mollasc* united to the genus Synoicum of modern authors. DIDYMOCARPE^E. See CYRTANDRACE*:. DIGITALIS (Linnteus). A well-known germs of European herbs, some of which are biennials, though the chief part are perennials. Linnaean class and order Didynamia Angiospermia, and natural order Scro- phularia. The foxglove is common on every hedge- bank, and no wild plant is more ornamental than this. In the gardens there is a white variety, though this is also found wild in some places. Two plants, namely, Isojilexis Canariensis, and /. sceptmm, were formerly ranked among the foxgloves, but are now separated by Dr. Lindley. All are easily propagated by seeds. DIG1TARIA (Scopoli), is the common finger- grass of Britain, and elsewhere. DILATRIS (Linnaeus). A genus of greenhouse perennials from the Cape of Good Hope. Class and order Triandria Monogynia, and natural order Hcenw- doraceee. Generic character : calyx corolla-like, of six petals, hairy without, and regular ; stamens six, inserted in the base of the calyx ; three of them short and sterile, and three long ; style filiform ; stigma simple ; capsule three-celled ; seeds three or six pel- tate. The bulbs or tubers of this plant thrive best in sand and leaf-mould, and are increased by offsets or seeds. DILL. Is the Anethum graveolens of Linnaeus, and is cultivated as a pot or sweet herb in gardens : it belongs to the same family as the fennel, so much used as a sauce for mackerel, &c. DILLENIA (Linnaeus). A beautiful and large forest tree, a native of India, named in honour of J. T. Dillenias, once botanical professor at Oxford. It belongs to Polyandria Polygynia, and gives a title to one of the Jussieuan orders, viz., Dilleniaceee. — Generic character : calyx of five, leathery, persisting sepals ; petals five, and somewhat leathery ; stamens very numerous, inserted into the receptacle ; anthers oblong and erect ; style none ; stigmas level, persist- ing, and disposed in a circle; berry many -seeded and many-celled. This is one of our first-rate stove plants, and may be propagated by cuttings, or, which is better, by imported seeds, sown as soon as they arrive in this country. Mr. Sweet observes of this plant that the leaves are so delicate, that tobacco smoke, or a tem- perature below sixty degress of Fahrenheit, injures them very much. DILLENIACE^E, a natural order of dichlamy- deous dicotyledonous plants, containing sixteen known genera, and about one hundred species. It is closely allied to magnoitaceae, from which is is distinguished by the want of stipules and the quinary arrangement of the parts of fructification. It also bears an affi- nity to RanunculacetB, but differs in its habit and in its persistent calyx. The essential characters of the order are : perianth with an imbricated aestivation ; sepals five, persistent, two exterior and three interior ; petals five, deciduous in a single row, hypogynous ; stamens numerous, hypogynous, arising from a torus, either distinct or polyadelphous, and either placed irregularly round the pistil or on one side of it ; filaments filiform, dilated 28-2 DILLWYNIA— DION^EA. either at the base or apex ; anthers adnate, two- celled, the cells generally opening longitudinally and internally ; ovaries definite, more or less distinct, with a terminal stj'le and simple stigma ; fruit consisting either of from two to five distinct unilocular carpels, or of a similar number cohering together, the carpels being either berried or two-celled ; seeds ovate, arranged in a double series at the angle of the carpels or cells, two or many, sometimes solitary, surrounded by a pulpy arillus ; testa hard ; embryo minute, lying at the base of fleshy albumen. The plants belonging to this order are : trees, shrubs, or under-shrubs. Their leaves are almost always without stipules, alternate, rarely opposite, commonly coriaceous, with strong veins running straight from the mid-rib to the margin. Their flowers are solitary, in terminal racemes or panicles, and often of a yellow colour. The greater part of these plants are found in New Holland. Some of them grow in India and in the southern parts of America and Africa. In general they possess astringent properties. The order has been divided into two distinct sec- tions : I . Delimacetc, or Delimete, including the genera Delima, Tetracera, Davilla, &c., in which the filaments are filiform, dilated at the apex, and bear on each side a round distinct cell of the anther. 2. Dillcnas, com- prehending the genera Dillenia, Hibbcrtia, Pleurandra, Candollea, Culbertia, &c., in which the filaments are not dilated at the apex, and the anthers are elongate and adnate. The genus Dillenia, whence the name of the order is derived, furnishes six known species, some of which are applied to useful purposes. DWenia speciosa is a splendid tree, forty or fifty feet high, found in the forests of Malabar and Java, which bears beautiful yellow flowers, larger than those of the water lily, and yields a pulpy acid fruit, the size of a large apple. The tree has a thick stem and rugged bark, and when wounded discharges an astringent watery fluid. The calyx of this species, as well as that of Dillenia scabrella, when in a young state, has an agreeable acid taste, and is used in curries by the inhabitants of some parts of India. Hibbcrtia volubUis is a green-house plant, well known for the beauty of its flowers and the peculiar fetid odour which they emit. Hibbertia dentata is a very ornamental green-house plant, and is admirably adapted for trellis ; when supported with a stake, it will reach the height of six or eight feet, and has a beautiful appearance with its rich yellow flowers, which continue to expand during all the summer months. Decoctions of the leaves and bark of Davilla rugosa and elliptica are used in Brazil as astringent washes for wounds and ulcers, and are applied to swellings of the legs which often occur in warm countries. The leaves of Delima sarmentosa and several other pecies of that genus are so covered with asperities, that they are employed in China in place of a file, and are used for polishing furniture. The fruit of many plants of this order when mixed with water is used in India as an acidulated drink in fevers. DILLWYNIA (Smith). A genus of Australian evergreen shrubs, consisting of above eleven species, all introduced since 1794. They are decandrious plants, and belong to Lcgimrinosce. Generic character : calyx of two lips, and five-cleft ; corolla standard broad, unequally two-lobed ; petals and stamens in- serted in the middle of the calyx ; style crooked ; pod bellied, two-seeded ; seeds like a string of beads. These plants thrive in moor-earth, and require well drained pots. Cuttings root freely in sand. DILUVIUM. A term employed by geologists to describe one of the principal deposits which is found on the surface of our globe. A diluvial soil owes its existence to the violent action of water, or some other powerful agent operating for a considerable length of time on masses of the hardest bodies. Thus we find the most compact rocks, such as basalt, worn away and converted into an impalpable powder by natunil processes, and at other times great blocks of granite removed from their earth-bound sites, and carried to distant plains, where such masses could not originally have been placed. DlMEKA(Latreille). In the first edition of the Regne Animal, the curious little family of coleop- terous insects PsclapMdec, was raised to the rank of a section under this name, from the incorrect observa- tion of the tarsi, which were supposed to be only two- jointed. As, however, the observations of more recent authors proved themtobe at least three-jointed, thesec- tion has been suppressed in the late works of Latreille. D1NETUS (Sweet). A genus of climbing plants, annuals, and perennials- They are pentandrious, and belong to the natural order Convolmdacece. Generic character : calyx in five parts ; corolla bell-shaped, in five equal erect segments ; stamens as long as the corolla, filaments joined to the tube ; anthers roundish ; style bifid ; stigma headed ; seed-vessel two-celled, four-seeded. The perennial species are increased by cuttings ; the annual species are either greenhouse or open air plants, climbing quickly and producing flowers in autumn. This genus was formerly called Parana by Burmann, but separated by the late Mr. Sweet. DIOCTRIA (Meigen). A genus of dipterous in- sects belonging to the family Asilidce. (See this article under that of BOMBYLID^:.) The antennae are placed upon a peduncle with the terminal style minute, and the basal joint longer than the following. The body is also long and narrow. They fly with great strength, and some of the British species have the wings black, and glossed with blue, which gives them a very exotic appearance. Their habits are similar to those of the AsilL DIODON — globe fish. Agenus of fishes belonging to the order Plectognathes, and family Gymnodontet, an account of which will be found under the last of these words. DIOMEDIA (Cassini). A West Indian genus of evergreen shrubs, bearing yellow compound flowers, formerly ranked among the Bnphalmums by Linnaeus. These plants have silvery leaves, grow in light com- post, and are propagated by cuttings. DION^EA (Linnaeus). This genus of plants con- sisting of only one species, is found in Carolina in North America. It belongs to Decandria Monogynia, and to the natural order Droseriaccce. The flowers are by no means striking, but the foliage is most remarkable, not only in form, but for its irritable properties, and con- sequent spontaneous motion. Each leaf is composed of three parts ; a lower principal leaf, with two leaflets at its end. The leaflets are somewhat semicircular, and articulated close together upon a gland-like body at the point of the principal, as already stated. The articulations act like hinges, permitting the leaflets to fall back from each other, and remain in a nearly hori- D I O N Y X — D I O S C O R M. 283 ontal position. While so spread open, should a lirsty or honey-seeking fly, or other insect, venture etvveen the leaflets so as to touch the gland, they istantly start up together with considerable force, and hitch the prisoner ; nor can the intruder easily extri- ate itself, because the inner edges of the leaflets are :irnished with opposing ranks of short bristles, which hut into each other like the teeth of a rat-trap ; so liat a fly has no means of escape, more especially as he leaflets do not open again for many hours. Tho ame motion is produced by touching the gland with he point of a straw or other body. Some naturalists are of opinion that this extraordi- lary mechanism of the plant is a provision for supply- ug itself with putrified animal food ; and have gone ;o far as make the plant catch morsels of raw beef or nutton, with a view to fattening, or increasing its ,-olume. Nay, more, that the plants so feasted grew he better for it ! — but this requires confirmation. The vulgar name of the Dioncea is " Venus's fly- Tap ;" it is a low inconspicuous marsh plant, and, when cultivated in nurseries for sale, is planted in bog-earthy :urf in a pot kept constantly in a pan of water, as the plant must never be allowed to get dry; but by no means should it be ever flooded. Whether kept in a greenhouse or frame, they should have a hand-glass placed over them, to ensure a more equable degree of moist air : at the same time fresh air is necessary, th hand-glass never being kept quite close. DIONYX (Dejean). A curious genus of minute coleopterous insects, belonging to the family Psela- phidte, allied to Statists, but having the labial palpi armed laterally with several spines ; the antennae have the four last joints very long. A single specimen ol this curious insect has only yet been discovered : it was captured by Dejean, on the wing, in the even- ing, in the department of Aude, during his militar} campaigns. D1OPSIS (Linnaeus). A genus of dipterous insects belonging to the great family Muscidte, and distin- guished from every other dipterous genus by having the eyes and antenna) placed at the extremity of horny slender footstalks, rising from the sides of the head and being in some species as long as the entire body which gives these insects a very remarkable appear ance. They are of great rarity, and seldom found ii collections. They inhabit the tropical climates o India and Africa, and but little is known of their habit? Above a score distinct species are described in a monograph upon the genus, published in the last par of the Transactions of the Linnean Society. DIOSCOREA (Linnaeus). A genus of herba ceous plants, some few of which are eminently usefn to the inhabitants of the countries where they natu rally abound. LinnJEan class and order, Diced Hexandria, and natural order Dioscorece ; Generi character : perianths superior, six-cleft, persisting stamens inserted into the base of the perianths filaments awl-shaped ; anthers two-celled ; styles sim pie ; capsule triangular, three-celled, in each two com pressed winged seeds. The D. alala is the yam o India. The tubers are as large as a child's heac rough and black exteriorly, but when boiled, remark ably white and mealy within, and very little inferio to the best potato. They affect light sandy land ; an in some of the East-India port towns, may be had i considerable quantities for ship's stores, which kee well for a month or two on board ship. In our ho house collections they are grown in light soil, an ained up to stakes or upon a trellis, and are in- reased by parting the roots. These, however, are ever cultivated for use. DIOSCORECE, the yam family,a natural order ot monocotyledonous plants, containing five or six known enera and upwards of fifty species. It is nearly Hied to Smilacea; in structure and habit, but differs n the character of its ovary, its capsular fruit, and in ts albumen, having a large cavity. In many respects t approaches the dicotyledonous structure. Its essential characters are : flowers dioecious ; >erianth six partite ; in the sterile or male flowers here are six stamens inserted into the base of the egments of the perianth ; in the fertile or female lowers, the ovary is three-celled, each cell containing >ne or two seeds ; style deeply trifid ; stigmas undi- rided ; fruit leaf-like, compressed, with two of its cells ometimes abortive ; seeds flat, compressed ; embryo mall, included in a large cavity of the cartilaginous ilbumen, near the hilum. The plants of this order are twining shrubs, with ilternate, occasionally opposite leaves, which are generally reticulated with veins, as in the dicotyledo- nous plants. The flowers are small, spiked, and have rom one to three bracteas. They are found in tropical countries in both hemi- spheres, and possess in general mucilaginous and nutri- tive properties. The chief genera of the order are, Dioscorea, Raja- nia, Testndinaria, Oncus, and AZchma. Tamus, or the alack bryony, which was formerly included in this order, is by Loudon and others referred to a distinct order, called Tamcae. Dioscorea furnishes numerous species which are found in the East and West Indies, and in North and South America. They are commonly known by the name of yams, and are interesting as furnishing large fleshy, sweet tubers, which are considered an import- ant article of food in all tropical countries. Dioscorea saliva, the common yam, is largely culti- vated in the West Indies, where it serves for food to the negroes. It yields large thick tubers a foot broad, which have a mealy taste, and are esteemed nutritive and easy of digestion. They are eaten instead of bread, either roasted on the embers or boiled. The flour got from them is made into puddings. The flesh of the yam is white or purplish arid viscid, but becomes farinaceous and mealy when dressed. The fresh juice of the root is acrid, and excites itching on the skin. There are many varieties of the root. Dios- corea aciJeata is by some looked upon merely as an, improved variety of the common yam. It is exten- sively cultivated, and yields tubers which are fre- quently three feet long, and weigh thirty pounds. All the edible species and varieties of Dioscorea are propagated in foreign countries like the common potato, but they arrive much sooner at maturity. They are planted in August, in rows two feet apart, and eighteen inches distant in the rows, and they are ripe in November or December. Tcstudinaria elephantipcs, common elephant's foot, is a native of the Cape of Good Hope, and is fre- quently cultivated in green-houses in this country. This plant has a singular appearance on account of its large fleshy root, a foot in diameter, which rises above ground and is covered with angular brown knobs having a tesselated aspect. The name testudinaria is derived from the resemblance between this root and the clumsy shell of some huge tortoise. The term 284 DIOSME.E — DIOSPYRUS. elephantipes, or elephant's loot, has also been appliec on account of the remarkable appearance of this root- stock. The stem of the plant is slender and climb- ing, and presents a remarkable contrast to the root. The flowers are small and insignificant. The Hot- tentots, in time of scarcity, use the fleshy inside of the root as a sort of yarn. DIOSME^E— The Buchu family. A natural order of dicotyledonous plants, containing nearly twenty genera, and upwards of one hundred and twenty known species. It is closely allied to Rutaceee, and by many botanists is considered merely a section of that order. It differs, however, in the peculiar structure of its fruit, and in having two ovules in each cell. It also bears an affinity to Xanthoxylece, Simarubaceee, Humiriacecc, and Auranliacece. The essential characters of the order are : flowers hermaphrodite, regular or irregular ; calyx consisting of four or five divisions ; petals as many, distinct or united, rarely wanting ; aestivation generally twisted, convolute, rarely valvate ; stamens equal to, or double the number of the petals, sometimes, by imperfection, fewer, hypogynous, or rarely perigynous, placed on the outside of a disc or cup surrounding the ovary, and either free, or combined with the base of the calyx, or sometimes wanting ; ovary sessile, stalked, its lobes equal to the number of petals, or fewer ; ovules twin and collateral, or one above the other, very rarely four ; style single, sometimes divided at its base into as many parts as there are lobes of the ovary ; stigma simple or dilated ; fruit consisting of several capsules, either cohering firmly, or more or less distinct ; endocarp, or internal skin of the fruit, entirely separating from the sarcocarp (or fleshy matter under the skin), which opens internally by two valves ; the endocarp also two-valved, the valves opening at the base, but connected by a membrane •which bears the seeds ; seeds twin or solitary, with a testaceous integument ; embryo with a superior radicle, which is either straight or oblique ; no albumen. The plants belonging to this order are trees or shrubs, rarely herbs. They are furnished with exsti- pulate, opposite, or alternate simple or pinnate leaves, which are covered with pellucid resinous dots. Their flowers are axillary or terminal, and of a white or reddish colour. The greater part of them inhabit the tropical parts of the globe. They are found abundantly in the warm regions of America, at the Cape of Good Hope, and in New Holland. A single genus is found in the south of Europe. By some authors this order has been divided into sections according to the countries in which the plants are found. Thus we have, first, the European section, including the genus Dictamnus, found in the south of Europe ; second, the Cape section, including the numerous species of Diosnia, Adenandra, &c., found at the Cape of Good Hope ; third, the Aus- tralasian section, comprehending the genera Boronia, P/iebalium, Correct, Erioslemon, &c., found in New Holland and Van Diemen's Land ; and, fourth, the American section, including the genera Evodia, Galipea, &c., which grow in South America, the West Indies, New Zealand, the Friendly Islands, and Mexico. To this last section are referred the Cusparieee of Decandolle. This division of the order, according to the geographical distribution of the plants, is found to agree most remarkably with the character of their fructification. In general th-r plants of this order abound in essential oil, and possess aromatic, tonic, and antispas- modic properties. Many of them have been used in medicine. The genus Diosma, or Buchu, furnishes upwards of seventy species, almost all of which are natives of the Cape. They have a powerful and offensive odour, which is nevertheless relished by the Hotten- tots. Many of them have been recommended as antispasmodics and tonics. The leaves of Diosma crcnata (Barosma cremtlata of recent authors) resemble much those of senna, and are used in medicine under the name of Buchu leaves. They have been introduced into the Dublin Pharmacopoeia. The emit a strong aromatic odour, have a pungent taste, and yield by distillation a volatile oil. They possess diuretic and tonic pro- perties, and have been recommended in the form of infusion and tincture in some diseases of the bladder. Their activity seems to be owing to the volatile oil and resin which they contain. Diosma ericoides and other species are used by the Hottentots to scent the ointments with which they anoint their skin. Galipea, or Cusparia febrifuga (Bonplandia trifbliata of Willdenow), is a handsome South American tree, and yields the well-known Angostura or Cusparia bark. This bark occurs in commerce in pieces from six to twelve inches long. It is of a fawn colour, and is covered with a whitish rough epidermis. When powdered, it exhibits a yellowish brown hue. It has an aromatic, bitter, and somewhat astringent taste. Ac- cording to analysis, it consists of cinchonia, and a small quantity of brucia, combined with igasuric acid, muriate of ammonia, gum resin, extractive and volatile oil. The term Angostura bark is derived from the common name of the town of St. Thomas, near the Straits of the Orinoco, whence it is exported ; while Cusparia is derived from the native name of the tree. A spurious kind of cusparia bark is sometimes met with in commerce, which possesses poisonous properties, and appears to be the product of a species of strychnos. The epidermis of this false Angostura bark is covered with rust-coloured warty excrescences ; its powder is of a very light yellow, and it has neither the odour nor the aromatic flavour of the true bark. The li- chens which grow upon it, and the effect of different hemical agents, are also sufficient to distinguish it. Angostura bark possesses all the tonic properties of Peruvian bark, and is used as an aromatic bitter in tomach complaints, as well as in intermittents and dysentery. It is frequently combined with rhubarb, magnesia, and carbonate of potass, and is prescribed n the form of powder, infusion, or tincture. Evodia febrifuga, Ticorea febrifuga, and Ilortia Brazilians, yield barks which are used in Brazil in the ure of intermittent fevers. The root of Dictamnus albus, or Fraxinella, has a )itter aromatic taste, and was formerly used medici- nally as a sudorific and vermifuge. This plant abounds so much in volatile oil, that the atmosphere sur- rounding it actually becomes inflammable in hot dry weather. DIOSPYRUS (Linnaeus). Is the date-plum, a ^nus of trees and shrubs, indigenous to many diffe- rent parts of the world. Linnaean class and order, Polygamia Diaecia, and natural order Ebenacece. In our collections they are placed in the stove or green- louse, and are in these places treated like other ihuits. The hardy ones are seen in our shrubberies, DIPLOLEPIS-DIPPER. 28.5 and grow to good-sized shrubs. Some of the species are cultivated for their fruit in the eastern parts of Asia, and the D. cbenum yields the valuable timber called ebony. DIPLOLEPIS. A name introduced by Geoffroy for the gall-flies, which LimiEeus had previously termed Cynips. The former name, notwithstanding its incor- rect application, having been adopted by the French entomologists, has occasioned much confusion between these insects and those of the family Chalridida:, which Geoffroy misnamed Cynips. See the articles CHAL- CIDID^: and CYNIPID.S. DIPLOPTERA (Latreille). A division of sting- ing hymenopterous insects, comprising the various species of wasps, and distinguished by having the upper wings folded longitudinally when at rest. The antennae are generally elbowed and thickened at the tips : the eyes are notched on the inside. The collar is produced behind on each side as far as the base of the wings, ihe upper pair of which have two or three closed submarginal cells ; the body is smooth and polished without hairs (as in the bees) and, generally, of a black colour, more or less spotted with yellow or brown. The character upon which this division is founded, and from which it received its name (doubled wing), is one of those curious instances where we find a peculiarity of organisation which cannot, so far as we are enabled to perceive, have the slightest influence upon the habit of the species, and yet it is so con- stant that we look in vain throughout the whole of the extensive order Hymenoptera for any other in- stance of folded wings except in the group in ques- tion : and yet, if we look at the habits of the species, we find them to be sufficiently diversified to induce us to suppose that we might here find sufficient cause for such a marked peculiarity : but this is not the case. Thus, we find the Odyneri perfectly resembling the CrabronidcE and Cercmdes in the economy of burrow- ing into sand and wood, in order to form the cells in which they lay up a provision for their progeny, which are to be hatched from eggs deposited at the same time with the food ; whilst, on the other hand, in the true wasps, we have a social economy, similar to that of the hive. The Diploptera then, in respect to their habits, form two groups ; but Latreille has established two sections from the structure of the antennae, which in the first {Masarides) have the terminal joints soldered together, so as to form a club ; whereas in the second ( Vespides), including both the Odyneri and Vespae, the antennae have the joints distinct and composed, as usual, of thirteen joints in the males, and twelve in the females. DIPLOTHEMIUM (Martius). Is a genus of Brazilian palm, to which country it is confined ; nor is its history much known. DIPPER — Cinclus. A genus of birds belonging to the dentirostral division of Cuvier's great order Passeres, and to the thrush family in that order. The singular appearance and very peculiar habits of these birds render them objects of much attraction, not merely to professed ornithologists, but to all who are fond of observing the children of nature in their wild state. Accordingly these birds have received a great many popular names ; and systernatists have been as much puzzled, in what part of their artificial cabinets to give them a place. The fact of these birds having sepa- rate names in both the ancient and both the modern languages, which are spoken in Britain, is sufficient to prove the attention which they must have attracted even at a very early period. This bird is tho Mwy- alchen y dwfr of the Welsh, and the Gobha uisge of the Scotch Highlanders ; in England it is the water ouzel, the penrith ouzel, the water crake, the water crow, the water colly, and a variety of other names ; and with the Scotch it is the water pyet, the water craa, and various other names. In fact, in this country alone, it has got as many names as might suffice for a tolerably well-stocked aviary. The generic characters are, the bill of mean length, sharp in the cutting edges, straight, elevated in the culmen, rounded at the extremity, and with the point of the upper mandible bent over that of the lower. The nostrils are lateral at the base of the bill, longi- tudinal, and in great part covered with membrane. There are three toes to the front and one to the rear ; the tarsi are short, but longer than the middle toe. The wings are short and rounded, the first quill being short and merely a supporter to the second, and the third and fourth the largest in the wing. It is doubt- ful whether there is any more well made out species than one. Several have 'mdeed been mentioned, but without sufficient grounds, as it should seem ; and that which is mentioned as being an inhabitant of the peninsular Crimea on the north of the Black Sea, and named after Professor Pallas, by Temminck, differs from that met with in this country only in the colour, being all over of a rich, reddish brown, while our one is pied. The habits of the two are, however, described as being so nearly alike, and so little is known of the one named after Pallas, that a descrip- tion of the one which, though not common in any part of Britain, is pretty widely distributed over it, will suffice for popular purposes. Cinclus aquations, the dipper, is very generally dis- persed over Europe, seems capable of enduring all climates, and is understood to be resident all the year round in most of the localities in which it inhabits. With us, it may be described as being chiefly a moun- taineer ; but it is not so on many parts of the conti- nent, for it is found in Holland, in Jutland, and in many of the comparatively flat districts on the south of the Baltic and in Russia. It is also met with in the south, as in Spain, Italy, and the island of Sar- dinia, being particularly abundant by the banks of the smaller streams in the Pyrenees and the Alps. It is not, however, confined to the south and middle parts of Europe, for it is met with in the Faro islands, and it is not improbable that it may occur in Iceland. It occurs also in northern and central Asia, from Siberia to the north of Persia, though, from the habits about to be described, it is not found in the dry deserts. The dipper bears some resemblance in its general shape to the common wren, only the tail is shorter in proportion. The whole length, if we take the average of full-grown birds, is about eight inches, the stretch of the wing about ten or eleven, and the weight about two or three ounces. The colours arc, the head and back part of the neck amber brown ; the back and scapulars black, but with blackish grey on the margins of the feathers ; the throat, a small patch on the eyes, the sides of the neck, and the upper part of the breast, white ; the lower part of the breast and the rest of the under part of the body is chestnut-brown, passing into dark brown nearly black toward the vent, and having the under tail-coverts of nearly the same grey as the margin of the feathers on the back. The bill is blackish brown ; and the tarsi and toes grey, some- times inclined more to yellow, and sometimes to 285 D I P P E R. blackish blue. The female is very like the male, except that the head is darker brown, and the white on the breast dull coloured. The young- are grey on the head and part of the back, and have more white on the breast, but it is broke by mottlings, and they have also some white on the margins of the wing- feathers. Dipper. These birds breed early in the season, and con- etruct their nests in general with a great deal of care. The nest is formed under a projecting stone in a hole of the rock, or even in a hole of the wall, if the situa- tion is sufficiently retired and near the water. This nest usually consists of a great quantity of materials, generally vegetable, as the stems and leaves of aquatic plants, dry moss, and the leaves of trees ; but the structure is differently described by different authors, and may be different in different circumstances and under different exposures. Of course we do not know the instinct which leads birds to build nests differing so much from each other as they are in different species, or indeed what leads them to build nests at all ; but as they must in some manner be regulated by cir- cumstances, they will, of course, make their structures in accordance with these. If the nest is immediately under a projecting roof, it is natural to suppose that though the bird might give it a dome in a more ex- posed situation, it might be satisfied with a natural one where that presented itself. The eggs are de- scribed as being four or five, of a pure white colour, semi-transparent, long in their shape, and very much pointed at their small ends. This is sufficient to show that there is not much philosophy in an opinion •ometimes advanced, that the form of the egg bears some analogy to that of the bird ; for the dipper is in every way a short bird in its body, its wings, and its tail. The young dippers are ravenous eaters ; and the nest with young in it is easily detected by their chirping. Dippers are with us found only in the streams of hilly countries, which run over beds of sand or gravel, and have their waters clear and transparent ; and it is an especial frequenter of those little pools between the rapids, where trouts resort to deposit their spawn. — The spawn of fishes, their fry, when young and in the breeding pools, and water insects, are understood to form the chief subsistence of the dipper ; and us this kind of provisions is found more early in the season than almost any other food for an animal feeding bird, the dipper is enabled to find food for its young sooner in the year than those birds which resort to the hill and the brake in those localities. Indeed, though it is confined to the margins of streams, and to those of streams of a particular character, and there- fore not distributed in breadth over any part of the country, the dipper runs less hazard from famine than most other birds, except in severe winters, when it is frozen out. This, too, is a circumstance of rare occur- rence in most of the haunts of the dipper ; because, in most of those localities in which it delights, which are the dells of the secondary hills, not far from the low country, but always above those places at which the bottom begins to be oozy, and the water turbid with mud, there are always springs breaking out from such a depth as that they seldom freeze ; and there are many little animals which intrust their young to such springs, and thus, in case of necessity, furnish the dippers with food until the frost breaks. If the rivulet is open, the dipper is perfectly inde- pendent, because it can procure its food under the water as readily as on the bank. It is true that it is not web-footed, and consequently it is not a swimmer, neither are its general characters those of a water bird. Still it is a bird which can turn the water to great account, and it seems to know this as well, for it is apparently never happy but when the water is imme- diately within its reach, and always happy when it is so. It is seldom seen at any great distance from its favourite rivulet ; and when it is found at some little distance it is timid, as if it were without the security of that which forms its castle. When, however, it is near the water, it is far from being a shy bird ; but, though it is very easily seen, it is by no means easy to catch. Its usual action when sitting on the points of the little pieces of rock and detached stones in the pools, consists of a continual bending down of the head, and a flirting up of the tail at the same time ; and it is from this peculiar motion of the head, and not from the fact of its getting into the water, that it is called the dipper. From the shortness and broadness of its wings, and the compactness of its body, it gets very quickly into flight, and it skims along the surface of the water, almost touching with its wings at every stroke ; and, when flying in this manner, it appears to get on more rapidly and with less fatigue than when it is higher above the surface. It is highly probable that all birds which have this habit of skimming along the surface of the water, find a relief in so doing, not only from the cooling, but from the greater resistance which is there offered to the down stroke of their wings, from the difficulty with which the air escapes from between the wing and the water. The dipper can get under water with great facility, and walk along the bottom, and probably also come to the surface, and take wing from the water ; though in general it comes to the bank for this purpose. Its plumage is very waterproof, and it is never wetted or ruffled by these immersions, one of which would effec- tually prevent the flight of any ordinary land bird. It has sometimes been objected to this under-water habit of the dipper, that as it cannot swim on the surface like the aquatic birds properly so called, or run on the surface like some of the long-toed birds, it cannot get below, because it is specifically lighter than the water, and has no purchase of the feet from which to thrust itself down ; but the dipper turns its head and it* wings to very good account in performing this opera- tion. The dipping motion of the head gets that part under water ; and the wings are partially under water at the §ame time. Then the elevation of the head, DIPSACEjE — DIPTERA. 287 and the raising of the wings, converts these into levers for the depression of the body ; and by this means it gets very speedily under water, — so speedily, indeed, that it appears to run down the bank to the bottom with no more apparent effort than what is necessary for simple progressive motion. When it is overhead in the water, the wings, and partially also the head are used with great neatness and effect ; and the upward stroke of the wings, even in that case, serves to keep the body to the bottom against any difference of gra- vitation there may be between the bird and the same bulk of water. In this way it can pick up and even pursue its food below water as easily as a common ground bird can do on the surface of the earth ; and as, when below the surface, it always holds the wings recovered, that is, at such a distance from the body as that they can strike first either upwards or down- wards, it can move with equal celerity in any direction. This need excite no surprise ; for though wings are not the usual instruments of motion below water, yet the difference between the wings in the air and in the water is more a question of their being proof against the action of water than of any thing else, because in the matter of specific gravity, it requires no very great degree of mechanical acumen to perceive, that it is not more difficult for a bird, by muscular exertion, to keep itself down in a fluid specifically heavier than itself, than it is to keep itself up in a fluid specifi- cally lighter ; and, as the difference between the spe- cific gravity of the dipper, and that of water, is really less than the difference between the specific gravity of any bird and air, the dipper has an easy task. We forgot to mention that the dipper is a sort of song- ster in the early part of the year, though not a very melodious one ; yet it is cheerful to hear a bird sitting on a stone in the brook and singing, when the banks of that brook are covered with snow. The summer note is a mere chirp. DIPSACE^;. The teasel or scabious family, a natural order of dicotyledonous plants, containing eight genera, and nearly one hundred and twenty known species. It is closely allied to Composites, but differs in its distinct stamens and pendulous albu- minous seeds. It also bears an affinity to Calycereee, from which it is distinguished by its free anthers and inverted embryo. It bears likewise a relation to Valerianeee, but differs in its habit, its capitate flowers, and in having an involucellum. By these characters it is also separated from Caprifoliacece. Its essential characters are : calyx superior, mem- braneous, resembling pappus, surrounded by a scarious involucellum. (This involucellum is a peculiar organ, resembling an external calyx, and may be said to cor- respond in some degree with the partial involucre ol the umbellifertf.) Corolla monopetalous, tubular, in- serted in the calyx ; limb oblique, four or five lobed, with an imbricated aestivation ; stamens usually four, inserted into the tube of the corolla, alternate with it lobes ; anthers distinct, two-celled ; ovary inferior, one- celled, with a single pendulous ovule ; style filiform ; stigma simple, longitudinal or capitate ; fruit dry, in- dehiscent, one-celled and one-seeded, crowned by a pappus-like calyx ; albumen fleshy ; embryo straight radicle superior. The plants belonging to this order are herbs or undershrubs, with opposite or verticillate leaves, and densely capitate flowers, which are surrounded by a many-leaved involucre. They abound in the soutn of Europe and north o Africa. Some are also found at the Cape of Good Hope and the Levant. In general they shun cold, and do not reach a great elevation above the sea. Their properties are not deserving of much atten- tion. Many of them are bitter and tonic, some are used on account of their astringency in dyeing, and a Few possess febrifuge virtues. The chief genera of the order are Dipsacus, Scabiosa, Knautia, Marina, and Pteroccphahis. The genus Dipsacus, or teasel, includes thirteen species, of which three are natives of Britain. Dip- sacus fullonum, fullers' teasel, is so called on account of being used in dressing cloth, for which purpose the hooked scales of its receptacle are admirably adapted. These are fixed round the circumference of a large broad wheel, which is made to revolve, while the cloth is held against them. By long cultivation in a poor soil, the hooks of the receptacle are said to disappear. By some botanists this species is looked upon merely as a variety of Dipsacus sylvcstris, or the common wild teasel. Dipsacus pilosus, small teasel, is the hanu sorriest species. Its seeds are eaten by small birds. The axils of the leaves of the common teasel usually contain a quantity of limpid water, which is sometimes very acceptable to travellers. The genus Scabiosa, or scabious, includes sixty-one known species,only two of which are natives of Britain. Scabiosa succisa, Devil's-bit scabious, is common in meadows and pasture land. It derives its name from the circumstance of its root being as it were cut or bitten off abruptly. It is said to yield a green dye, and also to be sufficiently astringent for tanning. Scabiosa alropurpnrca is rather a handsome species, bearing dark purple flowers, and is cultivated as a border annual or biennial. The leaves of Knautia arvensis, common field scabious, have a sharp and rather bitter taste, and were formerly recommended in cutaneous diseases. DIPSACUS (Linna3us). A genus of European herbs, one of which is the well-known clothiers'-brush, or teasel, found wild as well as cultivated in England. It belongs to the fourth class and first order of Lin- naeus, and gives a title to an order in the natural sys- tem, namely, Dipsacecc. Some of the species are admitted into the flower-garden, and are raised from seeds. The cultivated teasel is, like the rest, a bien- nial, and is sowed in drills, and kept clean and thinned by the hoe in the first year ; in the second, the plants are also kept clean, and when the heads are ripe, they are cut for sale. DIPS AS (Leach). A genus of molluscs now forming a subdivision of the genus ANODON, under which it is described. DIPTERA. An order of insects belonging to the great division Haustellata, or those furnished with a tubular proboscis, and distinguished by the presence of only a pair of membranous extended wings affixed to the centre of the sides of the thorax, and generally furnished near their insertion with a pair of short clubbed organs, termed halteres or balancers, respect- ing which, as. analogically representing the posterior wings of the four-winged insects, entomologists are at variance ; the mouth is provided with a sucker com- posed of from two to six scaly lancet-like pieces, and enclosed in a canal upon the upper surface of a fleshy proboscis, or covered by one or two inarticulated plates which serve as a sheath (Hippobosca). The body is composed, as in the other six-legged insects, of three principal divisions representing the head, thorax, and abdomen. The ocelli, when present, are generally three in number ; the antenna1 exhibit various* 388 D I P T E R A. which, being the lowest part of the mouth, corresponds with the lower lip of the beetle. At the sides of this, and rather higher in the mouth, is attached a pair of lancet-like organs, having a pair of large biarticuiate palpi arising from the base,— these constitute the maxillae and the maxillary palpi. Still higher in the mouth another pair of lancets appears, which repre- sent the mandibles, whilst a larger horny piece, chan- nelled beneath for the reception of the others, and which forms the upper lip (labrum). Within the mouth another very fine lancet appears, analogous to the tongue of the grasshoppers, an organ seldom de- veloped to any extent in the coleoptera. When we consider the habits of these insects, it is evident how necessary it is that the organisation of the mouth should be fitted for a different employment from that of masticating. These habits are essentially suctorial, and the food of the insects is essentially fluid ; broad horny organs would therefore be useless, whereas a series of acute instruments for puncturing and pene- trating deeper and deeper into the food, and a fleshy canal, up which, by suction, fluids easily pass, is what would exactly be looked for in the workmanship of an omniscient and all providing Artificer. In other groups of dipterous insects, and more especially in those which prey upon their companions (Atiltda-, JEmpidid<£, Nemexlrinidie, Sombyliidfe, Anthracidce). C (Fam. Therevidce, Lt-ptida:, Doli- chopida;, Syrp/iidtz). Subdivision 8. (Dichcetd). Sucker with two lancets. This subdivision comprises an im- mense assemblage of species, constituting the Linnaeatn genera Oestrus, Conop.i, and Mtflfoa, after the removal of the Syrphidce -, but, owing to the numerous divisions and subdivisions ne- cessary for its investigation, having but little to interest the general reader, we shall not here detail them. Section II. (Pupipara ; HOMALOPTRRA, Leach). Head immersed in the front of the thorax ; sucker enclosed in two valves ; claws with many teeth. The transformation to the pupa state undergone in the body of the parent fly. Fam. 1. (Hippoboscidte). Head frontal. Fam. 2. (Nycteribiidce). Head dorsal. DIPTEROCARPEjE— the camphor tree family. A natural order of dicotyledonous plants, containing only a few genera and species. It is closely allied to ElceocarpccE. but differs in its petals not being fringed, and in the want of albumen. It bears also an affinity to Malvacea;, from which it is distinguished by its stamens being either distinct or only partially combined, by its long narrow two-celled anthers, and its pendulous ovules. To Gutfifcrce it has also some affinity, but it is separated by its stipules and the contorted aestivation of its corolla. This order may be at once recognised by the enlarged leafy and unequal segments of the calyx while investing the fruit. Its essential characters are: calyx tubular, five-lobed, unequal, without bracteas, and imbri- cated ; petals sessile, combined at the base with a twisted aestivation ; stamens indefinite, distinct, or imperfectly polyadelphous ; filaments dilated at the base ; anthers awl-shaped, two-celled, opening longi- tudinally towards the apex ; ovary superior, few- celled ; ovules in pairs, pendulous : style and stigma simple ; fruit coriaceous, one-celled, indehiscent or three-valved, surrounded by the enlarged foliaceous calyx ; seed single, without albumen ; cotyledons twisted and folded, or unequal and obliquely incum- bent ; radicle superior. The plants of this order are large and elegant forest trees abounding in resinous juice. Their leaves are alternate, involute, with numerous parallel veins running from the midrib to the margin. They have de- ciduous oblong stigmas which terminate the branches in a taper point, and their flowers are generally large. They are found only in the eastern islands of the Indian Archipelago. This order, though small, is important on account DIRC A— DISCOBOLUS. 291 of the resinous juice which it furnishes. Its properties may be said to be stimulant and balsamic. The chief genera of the order are, Dipierocarpus, Dryobalanops, Shorea, and Valeria. Dryobqlanops Cuniphora is interesting on account of yielding the camphor of Sumatra. In that island this tree is confined to the country of the Battas, which extends about one degree and a half to the north of the equator, It is also found in Borneo in nearly the same parallel of latitude. The camphor is found in a concrete crystallised state in fissures and cavities in the interior of the tree. It is less volatile than the common camphor of commerce, which is the product of Laurus Camphora, a native of Japan and China. On account of its scarcity it bears a very high price. It is little known in this country, or even in Europe. An oil is procured from the camphor tree by incision, which is supposed to be the first stage of the formation of camphor. An account of camphor and its medical uses will be given under the article LAXJRINEJE. Shorea robusta affords a balsamic resin, which is used in the Indian temples. By boiling the fruit of Vateria Indica, a tree com- mon on the Malabar coast, a kind of tallow rises to the surface which concretes on cooling. It is whitish, greasy to the touch, and has rather a disagreeable odour. It is extremely tenacious and solid, but melts at the temperature of 97^° Fahrenheit. In the town of Mang-alore it is sold for about twopence halfpenny a pound. DIKCA (Linnaeus). A small deciduous shrub, native of Virginia, in which country it is called leather- wood, perhaps from the toughness of the fibres of the inner bark. The flowers are inconspicuous, are octan- drious, and the plant belongs to the natural order ThymdaECE. It is usually planted among North Ame- rican plants, and is propagated by layers. DISA (Bergier). A genus of curious flowering plants, natives of the Cape of Good Hope. Linnsean class and order Gynandria Monogynia, and natural order Orc/iidece. These plants thrive best planted in a pit with other Cape bulbs or tubers, in soil com- posed of loam, moor earth, and sand. They only need water when in a growing state. DISCINA (Lamarck). This genus of molluscs has been so called from each valve presenting, near the centre, a remarkable and very distinct orbicular disk ; that on the superior or upper side is smooth and pierced, exhibiting in its centre a small papillary ele- vated summit, giving it much the appearance of a patella : it is also surrounded by a margin longitudin- ally marked with delicately radiating striae. The disk of the lower margin is very white, obliquely crossed by a notch or cleft, open on both sides. Although the valves of the shell are of an equal size, they are not exactly similar, the upper one being rather more con- vex, and the lower without striae round its disk : there are no traces of hinge, ligament, or muscular impres- sions visible. It is found on the British coast affixed to stones. Sowerby observes this genus should be entirely expunged. Lamarck having constituted it from examples of the Orbicula, without mature con- sideration, it therefore must now form a subdivision of the genus Orbiculina. DISCOBOLUS, so called from the ventral fins, forming a disk on the under part of the body, by means of which the fishes are enabled to hold on upon the points of rocks, and there catch their food, which is brought to them by the currents. They form the third family of Cuvier's soft finned fishes, with the ventrals under the pectorals. They are fishes of small size, and altogether uninteresting for econo- mical purposes. They are, however, curious on account of their form, and of the habit which we have mentioned. There are only two genera in the family, and the species are not numerous. LEPADOGASTEII — the Sucker. The members of this genus are very small fishes ; their pectoral fins are very large, and reach the middle of the under part. They are composed of very strong rays, a little divergent in the front, and united by a membrane which is elastic, and which also includes the ventrals. Their bodies are smooth and without scales, the head depressed, and the muzzle projecting and capable of distension. Their gill openings are small, with four or five rays in the gill-flap. They have one soft dor- sal fin immediately over the anal. Their intestinal canal is short, straight, and without those appendages, which would show that they are animal feeders. They have no air bladder, notwithstanding which they swim with considerable rapidity. There are several species found in the European seas, and on the British shores ; but on the south and west rather than the east. The following are the British species. L. CORNUBIENSIS — the Cornish Sucker, is about four inches in length, and reddish, with dusky spots. When full grown there are two eye-shaped marks behind the eyes, with a brownish marginal ring, a bright purple disk, and a small spot of intense blue in the centre. There are also four little fleshy filaments in front of the eyes, and the snout is produced, rounded and flattened. They are met with on the coast of Cornwall, and also in some parts of the Hebrides ; and there is no doubt that if they were of any value to the fishermen they might be found upon all the rocky shores which are washed by the Atlantic, espe- cially where a current of tide sweeps along. They are met with at low water adhering to the rocks, by means of their disk. L. BIMACULATUS — Two-spotted Sucker. The length of this species is only about an inch and a half, and the body is more slender and the snout more pointed than in the former, and it is furnished with no appendages in connection with the eyes ; the general colour is pink spotted with white ; and when mature there is a spot of purple with a white margin behind each pectoral fin. This species is found in the Channel, and does not app.ear to be so decidedly a current fish as the other ; but it adheres to stones and shells. These two species have the dorsal and anal fins dis- tinct from the caudal ; but there are several species which inhabit the Mediterranean which have these appendages united. There is nothing, however, in their history which can particularly interest the general reader. CYCLOPTERUS — Circular Fin. The most remark- able structural character of this genus is that from which it is named. The ventral fins are united into one disk, which surrounds a considerable portion of the under side, forming a very efficient sucker, by which they can fix themselves firmly to rocks, to the bottoms of ships, or to the bodies of the larger fishes. Their mouths are large, and furnished with small pointed teeth in both jaws, and also in the pharynx. Their gill openings are small and closed below, with six rays in the flap. Their pectoral fins are very large, and they are continued and united under the throat, T2 •29-2 D I S P E II I S — D I V E R. in front of the disk formed by ihe pectorals. Their bones are soft, and their skin viscous and without scales ; but it is sprinkled with minute grains of a hard substance. Their stomachs are very large, their intestines long and abundantly furnished with caeca, characters which indicate habits very different from the former genus, with which they have sometimes been confounded. DISPERIS (Swartz). An orchideous genus from South Africa, which succeeds, if potted, or planted in a pit in compost made of a mixture of loam and peat earth. D1SPORUM (Salisbury). A genus of perennial herbs from China and Nepal. Class and order Hex- andria Monogynia, and natural order Melanthacece. Generic character : corolla of six petals, bell-shaped, nectariferous holes at the base of the segments ; sta- mens under the germen ; filaments very short ; style abbreviated ; stigmas three-capsuled, three-valved ; seeds membranous. According to Sweet, these plants are hardy enough to stand on a warm border, if sufficiently defended from frost. DIURIS (Smith). A genus of curious plants from New Holland, belonging- to the natural order Orc/ii- dece. They are much easier cultivated than the South American species of the same order ; only requiring to be potted in moor-earthy soil, and kept in a pit or green- house safe from frost. DIURNA (Latreille). A section of lepidopterous insects, corresponding with the Linnaean genus Papilio, or butterflies, being distinguished by having the mar- gin of lower wings not furnished at the base with a scaly bristle for retaining the upper wings in their proper situations, these, as well as the second pair, be- ing generally perpendicularly elevated during repose ; the antenna? are generally terminated by a club, and the larvae have sixteen legs. The perfect insect, always furnished with a spiral tongue, flies by day, and the under surface of the wings is not less beautifully varie- gated than the upper. Having, under the article BUT- TERFLY, entered at length into the natural history of these beautiful insects, we shall here simply give a slight sketch of their distribution into groups, esta- blished upon their diversities of structure. Fam. 1. — Papilionidcz. Anterior legs not abbre- viated, fit for walking, alike in both sexes. Pupa angulated, suspended, and braced across the middle. Antenna? not hooked at the tip. Here belong the genera Pujrilio, Zelima, Parnassius, Thais, Picris, Pontia, Colins. Fam. "1. — NymphaMee. Anterior legs abbreviated, not fitted for walking ; ungues bifid ; pupa angulated, and merely suspended by the tail ; middle cell of the lower wings closed. Genera : Cetfwsia, Argynnis, Melittea, Vanessa, Libyihea, Biblis, Nymphalis, &c. Fam. 3. — HdiconMce. Pupa smooth, suspended only by the' tail ; anterior legs imperfect ; dis- cordal cell sometimes open. Danais, Heliconia, Acreea, &c. Fam. 4. — Lyccenidce. Anterior legs semi-abbre- viated ; claws minute ; pupa smooth, braced, larva onisciform. Genera . Polyommatus, Tkecla, &c. Fam. 5. — Hesperiid<£. Anterior legs not abbre- viated ; antennas hooked at the tips ; pupa smooth, braced, and folliculated. Genera : Hespcria, Thymelc, &c. These characters, it will be seen, are in some degree derived from the preparatory stages of the insects ; indeed, these considerations afford much more import- ant clues to the classification of insects than thev were imagined to possess by the earlier authors upon this branch of natural history. Of those who adopted a contrary opinion, Schrank may especially be noticed. He consulted metamorphosis in its various modifica- tions, in his arrangement, and on its importance as a guide to minor sub-divisions, he has the following in- genious observations, quoted by Dr. Horsfield in his Lepidoptera Javanica : — " Metamorphosis, in its larva state, may, and I think must be taken into the charac- ters of the genus, in the absence of other sufficiently distinctive notices. Those botanists who have derived their systems primarily from the fruit, have neverthe- less a regard for the flower, and by this means recipro- cally elucidate existing obscurities. Caterpillars are the flowers of the lepidoptera. They are, indeed, not always present when the perfect insects are before the examiner. But is the case different with the botanist:*" And Mr. MacLeay says to the same effect : "As the knowledge of the whole life of an insect must make us better acquainted with its nature than a mere description of one of its forms, in the same proportion ought metamorphosis to outweigh every other prin- ciple of arrangement." DIVER — Colymbus. A genus of web-footed birds, and one of the most aquatic of the whole order. They appear in structure and in habits as literally made for the water, and the water only ; and they have equal command of themselves on and under the surface of that element. They are chiefly natives of the northern hemisphere, and of the more northerly seas, being birds peculiarly fitted for contending with the storm in the water itself, and probably getting to a greater depth than that to which the water is dis- turbed by the waves. They are especially abundant about projecting headlands in the northern countries, where the current runs strong, and the surf and spray occasionally beat with great violence. But amid the turmoil of the storm, the divers appear as much at home in the foaming water as the small birds do in the groves on the gentlest morning of May. In such situations they may be seen driving about, now appear- ing in the trough of the waves, now boring through the ridges, now on the wing for a little space, but anon plunging into the water. At such times and in such places the fry of fishes, which remain and feed much nearer the surface than stich as are full grown, are collected in abundance, and many of them lose command of themselves in the troubled waters, so that they are brought helpless to the line on its slope upon which the wave turns ; for it is to be understood that waves do not roll onward in rapid progressive motion as they have the appearance of doing to a spectator, they merely swing in times pro- portionate to their lengths, that is to half the distance between the bottom of the trough and the top of the ridge, as measured on the slope ; and as the turning point, or rather line, taken in the length of the wave, is the place of no upward or downward motion, it is there where the small fishes and other surface animals are accumulated while the storm lasts ; and it is to profit by those accumulations that the divers are found driving through the waves on such occasions. Cuvier makes the divers a family consisting of three genera, the divers properly so called, the grebes, and the guillemots ; but as the word diver is in this country restricted to the genus Colymbus, and as the DIVER. •293 guillemots have some differences of habit, we shall restrict this article to the divers properly so called. Their characters are : the bill of moderate dimen- sions, straight, compressed, and very sharp at the point ; the nostrils at the base, lateral, oblong, and half closed by a membrane ; the legs placed far be- hind, with the tarsi compressed or flattened sideways ; three front toes very long, and webbed to their points, and the hind toes short and united to the inner toe by a rudimental web. The legs are articulated very far backwards and wide of each other, so that though they act powerfully in the water they are very ill adapted for walking on land ; and when the birds attempt this, they are obliged to carry their bodies in nearly a vertical position, and roll them along with their steps, which are both short and awkward. The wings aie short, but remarkably close in their feather- ing ; and the tail is also very short and rounded. The form of the body is long and flat, the breadth being greater than the depth ; and the head and neck are comparatively slender, the former gradually fining off into the strong and sharp bill, which answers equally for seizing the prey or transfixing it by a thrust. The plumage over their whole bodies is re- markably close and compact, and how long soever they remain in the water they are never wetted. They spend the greater part of their time in the water unless when they have nests ; and as they are very energetic in their motions, they are very voracious in their eating. They are also very miscellaneous feeders, capturing fish, small marine animals, and not refusing vegetable food if it comes in their way. Their sum- mer quarters are chiefly in the north, where they form their nests upon small islands, or projecting headlands where they are subject to be but little dis- turbed. Their eggs are usually only two in number, and as is the case with the greater number of sea birds they make no formal nest. It is a fact worth attending to, as showing the difference between de- pending on the land and depending on the sea, that the eggs of land birds are, generally speaking, much more numerous than those of sea birds, while the sea birds themselves are much more numerous than land birds. Sea birds indeed, though they have at all times considerable labour in the finding of their food, have yet plenty of it at most seasons ; and besides, they are exempted from many of the casualties which land birds have to suffer ; and not the least of these are the attacks of beasts and birds of prey. From both of these the sea birds are comparatively free, and perhaps they owe some part of their safety to the unpalatableness of their flesh ; for many of them are so rank that it is doubtful whether even a starved raven, the least dainty perhaps of animals, would condescend to make a meal of some of them ; and as for the sea eagles and ospreys, they are more partial to a fish dinner. In the divers, the sexes do not differ greatly in appearance ; but the young differ so much from the old birds that they have been formed into separate species ; and not only this, but as the young require three years before they assume the proper plumage of maturity, and as they continue growing all this time, one species has sometimes been multiplied into four, by giving separate specific accounts of birds of one year, birds of two years, birds of three years, and birds in their plumage of maturity. We shall notice one or two of the leading species. THE GREAT NORTHERN DIVER— C.glacialis. This is a very large species, and one which attracts a good deal of attention. Its bill is upwards of four inches in length, with a strong ridge or keel above the nos- trils, and with the under mandible deepest in the middle, a form which gives much stiffness and power to that part of the organ. The size is subject to considerable variation ; but the largest are from two feet and a half to three feet in the length of the body, and from four feet and a half to five feet in the stretch of the wing's ; and when they are of this size, and fat, they weigh from twelve to fifteen pounds. The head and neck are black, but the neck is surrounded by two white collars freckled with black, the upper part is black powdered with white spots, and the under part white. In winter those birds frequent the north- ern parts of both continents ; but they breed in the marshes, or the fresh water pools, and not on the rocks. We believe few of them nestle on the main land, even in the northernmost part of Scotland ; but they are by no means rare in the western islands and the Orkneys, and they are met with in Norway, Sweden, and the north of Europe generally, and also in Iceland and Greenland, and in fact in all the coun- tries joining the Arctic Seas. In their breeding places they love retirement, and their nests are usually concealed among reeds or other tall aquatic herbage. Their eggs bear some resemblance to those of the goose, only they are very slightly spotted with black. The Great Northern Diver. To capture the eggs of the great diver, or the young birds, if the mother is near, is a matter of some hazard, just as the finding of the nest and getting at it are matters of some difficulty. It should seem that, in placing the nest, inaccessible ground, as well as con- cealment, were the object of these birds ; for they are generally in places where they can neither be reached in boats nor on foot ; and if they are reached, and the old bird is near, she makes a very determined, and at the same time, a very formidable resistance. Her bill 294 is darted out with nearly as much rapidity as that of a bittern, and as the bird is heavier, the bill thrusts like a bayonet, so that both bird and nest are tolerably well secured from the predatory quadrupeds of those places. In the summer season these birds subsist almost entirely on the smaller species of surface fishes, or the young of the larger ones ; and, notwithstanding their size and weight, in the capture of their prey their adroitness is very great. They have equal address in avoiding danger, which renders it very difficult to shoot them on the water ; for as they dive, the shot glances, and they are safe. Sometimes, however, they are taken, or rather take themselves, on the baited hooks of the fishermen's lines, and at other times they get entangled in nets at greater depths below the surface than one would be apt to suppose. In winter they migrate southwards, and on their migratory journeys they are capable of lofty and rapid flight. The young are the most prone to take these excursions ; and as they make their way to the inland lakes of France and Germany, and sometimes even as far as Switzerland. The descriptions of these young ones have led to some of the confusion which there is about the species. They are not rare upon some places of the north coast of Scotland in the winter season, but they seldom make their appearance on the English shores unless the winter is very severe. These birds, and indeed all the diving birds of the Polar seas, are remarkably well defended against the cold to which they are exposed in their dives. Their skins are remarkably strong and tough ; and the down upon them among the roots of the feathers is very close. They have also a pretty thick layer of fat all over the body, immediately under the skin. Their skins are so strong, and the down upon them adheres so firmly, that the people of the northern islands dress and tan them, and make of them very warm and durable articles of clothing. The voice of these birds is strong, harsh, and peculiar, and resembles more the barking of a dog than the sound uttered by almost any other of the feathered creation. They are in short altogether very extraordinary birds. RED-THROATED DIVER — Colymbus septcntrionalis. This is a much smaller species than the former, but it is more elegantly made. The length does not exceed two feet, or the weight much more than three pounds. The bill is about three inches long, slender and pointed, of a black colour, and slightly curved upwards. The crown of the head and back of the neck are purplish black with raised white margins to the feathers. The sides of the neck and head and cheeks are dark grey ; the upper part is very dark olive with the margins of the feathers paler, and the coverts of the wings dusky with white spots. The front of the neck is brownish-red, from which the name of red- throated diver is derived; the rest of the under part is silvery white with a black bar on the vent. The young differ considerably, not only from the old, but in the different stages in their own growth. At first they are all over dusky on the upper part, and dull white on the under ; and next the grey on the head appears, and the back is spotted. The third change which they undergo is the acquiring of the mature plumage, and the reddish brown on the throat. In some parts of the country, Orkney, we believe, this species is called the rain-goose ; because when it screams, or rather croaks, the people of that country say that it predicts rain. It is probable, however, that DIVING WATER SPIDER. there is not very much truth in this prophecy ; and yet many birds, both of the land and the sea, are apt to be clamorous before foul weather. , Like the former species, this one breeds in the marshes. It is more abundant in the more northerly of the Scottish islands, and more discursive to the British bays and estuaries in the winter, being found in the Thames, though not very frequently. The eggs of this species are very much elongated, of an olive brown colour, and marked with a few dusky spots. The nest is made with some care of moss and grass, and the female lines it with down from her own breast. Red-throated Diver. THE BLACK-THROATED DIVER — Colymbus arcticus. This one is a little larger than the former, being about three inches longer, four inches more in the stretch of the wings, and nearly a pound heavier. The front, the throat, the fore neck, and the back and rump are black ; the sides of the neck mottled black and white ; the sides of the back and scapules black with white spots. The habits agree pretty nearly with those of the others, the nests being also on the margins of lakes ; the eggs are also two in number ; but unlike those of the last species, they are white. The young are dusky above and white below at the first ; the head next becomes grey, and the sides of the head spotted with black ; and the last stage of the plumage is the appearance of the black on the fore neck, and the black and white mottlings on the sides of the back and the scapulars. DIVING WATER SPIDER (ARGYRONETA, Latreille), a genus of pulmonary arachnida, belonging to the family Arane'idce, but forming, according to Walckenaer, a distinct family named Naycudcs. The four central eyes form a quadrangle, the two lateral ones on each side touching each other, and placed upon a slight eminence ; the first and fourth pairs of legs are the longest. The type species Aranea aquatica (Linnseus), is very common, and of a brownish black colour, with the abdomen silky, and with four im- pressed spots on the back. It resides in slow running waters and ditches, in which it swims about with a bubble of air attached to its abdomen, and spinning a most beautifully constructed web of white silk, in the form of half the shell of a pigeon's egg, or like a diving bell, with the mouth downwards, as its retreat, at the bottom of the water, and which is attached by nume- rous threads to the surrounding plants. In this it 'devours its prey, and deposits its bundle of eggs.which D O C K — D O G. 295 it watches with great caro. In this also it passes the winter, having first closed the mouth. The males as well us the females construct these cells. DOCK. The vulgar name of a British weed called by botanists liii»n\i: Including the different sorts of sorrel, there are nine or ten species oi' Ituwex in Britain ; the large leaved are called docks, and the small leaved are called sorrels. DODO — Didus. A genus of birds inhabiting, or rather said to have inhabited, the island of Madagas- car, but which is now extinct, and indeed the existence of it at any time, as answering to the descriptions which are given by the older writers, is somewhat doubtful. The first description, or rather the only one which even pretends to be founded on actual observation, was given by the Dutch, when they first visited that part of the world ; and of which an oil painting was made about the same period. The de- scription and a copy of the painting were given by Cluseus in his account of exotic birds ; the picture was also copied by Edwards ; and from these sources the bird got into the popular books as a living inha- bitant of the earth. But the remains of it are very scanty, and it is doubtful whether they have all be- longed to the same kind of bird ; there is a foot in the British Museum, the mutilated remains of a head in the Ashmalean Museum of Oxford, and a skull, a sternum, and sonic bones of the extremities were sent to Paris, which last were discovered in a cave in the small island of Rodriguez, about a thousand miles to the eastward of Madagascar, about fifty years ago. The foot is webbed, and very like the foot of a penguin ; and if there ever was such a bird as the dodo, it must have been, like the patagonian penquin, nearly incapable of flight. The account given in the books is, that at the time when the Dutch first visited this Archipelago, that is, Madagascar and the small isles to the eastward, these birds were found in abundance ; but the result of all subsequent inquiry has been no- thing more than the fragments which we have men- tioned. There have been two species of this bird mentioned ; but one of them, Didus solitarius, and indeed another, Didus Nazarcnus, are certainly spuri- ous, and as no more of the third can be found, it scarcely belongs to popular natural history. Didr.- inept us. This species (Didus inept us), of which we give a figure, without vouching for its being a likeness of any bird that ever lived, is described as being one of the largest of the feathered race, but the most uncouth and unwieldy of the whole. Its colour is said to have been black, with only a thin covering of feathers, and the head covered with a membranous hood. Only four or five short black feathers in the place of wings, and a tuft of curly feathers instead of tail. The tarsi short, very thick and stout, and covered with brown scales ; the toes very short, webbed, and without any claws. The bill very large, yellow at the base, black at the tip, and blue in the middle portion of its length. The recent discovery of the apteryx (see the arti- cle APTERYX) on the island of New Zealand, and the fact that only the one specimen of that curious bird had been seen by Europeans, gave some ground for believing that there might possibly be in the southern hemisphere, which is remarkable for the singularity of many of its animals, some such bird as this same dodo ; but the form given to the bird in the picture, and the weight ascribed to it, namely more than fifty pounds, are rather contradictory of any hope of seeing it. The organisation of the apteryx is no doubt peculiar ; as the bird can neither fly nor swim, and from the shortness of its legs cannot be a very swift walker ; but the apteryx has still an orga- nisation which one can understand, and perceive that it is not badly adapted for the situations in which it is said to be found, the rocky and stony places on the east side of New Zealand. The dodo, as de- scribed, has on the other hand no distinct system of locomotion, and is quite a bird of the ultima thulc, fit for neither land, sea, nor air. The feet are webbed, but there is nothing to answer to them in swimming ; the absence of wings forbids the notion of an air bird, and the feet are not adapted for walking. DOG — Canis. A genus of carnivorous mammalia, and one of the roost interesting of the whole class. It consists of several sjenera, or rather perhaps sub- genera; the dog properly so called, the wolf, the fox, the jackall, and the hyecna, all of which produce hybrids, and, generally speaking, we believe fertile hybrids with each other; but though this warrants the consideration and description of all these animals as one group, and though they have many characters in common, yet they are so numerous, and the pecu- liarities of each are so distinct, that we shall perhaps best observe clearness of description, and propriety of arrangement, if we treat of them under their com- mon names of DOGS, FOXES, HYAENAS, JACKALLS, and WOLVES. These five divisions fail into two classes, which are founded upon their principal habits--. The dogs and wolves have the pupil of the eye round, and they are social in their predatory huntings ; and though these huntings are not confined to the day, yet they are, generally speaking, more of diurnal than of nocturnal animals. The foxes and hysenas, on the other hand, are less social in their characters, the foxes especially are of solitary habits, and they arc more nocturnal than otherwise, though the time at which they seek their prey is early morning rather than during the darkness of the night. The whole of the group however consists of animals which are peculiarly flexible in their characters ; and, the human race excepted, perhaps yield more to clirnatal £>nd local circumstances than any other family of carnivorous mammalia. They are found in all cli- mates, and they appear to have wonderful facilities of adapting themselves to the climate, being almost des- titute of hair in the very warm latitudes, but becoming 296 DOG. clothed with remarkably thick fur when carried to cold climates. This change, not in the same species merely, but in the same individual animal, is so re- markable that some of the dogs which were carried out by our voyagers and travellers to the polar regions of North America, and wintered in the extreme cold there, acquired a fur of so remarkable a thickness that while they crouched by the winter fires their fur was burnt in holes half way down to the skin without their being at all sensible of the heat. The character of the genus are, that they are digi- tigrade in their walking, or walk upon their toes, the claws of which are not retractile, or used in any way as prehensile instruments in the capture of their prey, which in these animals is uniformly captured by speed, and following either by sight or on the scent, the strength of the prey determining whether it shall be hunted singly or by a combined pack. The teeth are, six incisors in each jaw, and one strong canine in each side of each, with six teeth above in each jaw, and seven in each below. The first three behind the canines in the upper jaw, and the first four in the lower, have trenchant or cutting edges, adapted for bruising flesh; the great carnivorous teeth which follow these have two points in the upper jaw, with a small tubercle on the inner side. The two last teeth in each side of both jaws are also tuberculated at their summits. In those varieties which are found in a state of nature the muzzle is generally elongated, and the gape wide, the effect of the jaws in killing the prey being that of a snap, in which the rapid motion of the jaw gives effect to the weight ; and these spe- cies or varieties (for it is exceedingly difficult in this species of animals to say what is a species and what a variety) the ears are generally erect ; but in the domesticated ones the varieties are so numerous that it is hardly possible to give any description of them. No specific form or character of covering can be taken as generally characteristic of dogs ; for though their characters are always expressive of the family, as distinguished from every other race of animals, they differ so much from each other, in size, in shape, in the character of their covering, and are so in their propensities, that they have absolutely nothing of external character which will apply to the whole race. The length of their jaws and muzzle, and the shapes of their ears, are exceedingly variable ; but the tongue is always smooth, and instead of lacerating, like that of the cat family, its application to wounded or dis- eased parts has rather a healing tendency ; they have live toes on the fore-feet, and generally four on the hind ones, though in some of the varieties there is a partial development of the fifth one. The females go sixty-three days, and the litter consists usually of three, four, or five, though sometimes of as many as ten or a dozen ; the puppies are always produced with the eyes closed, and do not open them for ten or twelve days after. They live on the average about fourteen or fifteen years, but there are great differ- ences arising from climate, breed, and other circum- stances. If we take the domesticated races, and it is doubt- ful whether there are any dogs which have not been partially domesticated, though some have unquestion- ably degenerated, there are no animals which show BO much attachment to man ; and the anecdotes which are recorded of the fidelity of dogs would fill many volumes. Perhaps justice is not more effectually done to their characters in a general, and we may say unphilosophical view, than in the following passage which we quote from Mr. BurclielTs Travels in Africa : " Our pack of dogs," says Mr. Burchell, " consisted of about five and twenty of various sorts and sizes. This variety, though not altogether inten- tional, as I was obliged to take any that could be procured, was of the greatest service in such an expe- dition, as I observed that some gave notice of danger in one way, and others in another. Some were more disposed to watch against men, and others against wild beasts ; some discovered an enemy by their quickness of hearing, others by that of scent ; some for speed in pursuing game 3 some were useful only for their vigilance and barking ; and others for their courage in holding ferocious animals at bay. So large a pack was not indeed maintained without add- ing greatly to our care and trouble, in supplying them with meat and water, for it was sometimes difficult to procure for them enough of the latter ; but their ser- vices were invaluable, often contributing to our safety, nnd always to our ease, by their constant vigilance, as we felt a confidence that no danger could approach us at night without being announced by their barking. No circumstances could render the value and fidelity of these animals so conspicuous and sensible as a journey through regions which, abounding in wild beasts of almost every class, gave continual opportu- ties of witnessing the strong contrast in their habits, between the ferocious beasts of prey, which fly at the approach of man, and these kind but too often injured companions of the human race. Many times, when we have been travelling over plains where those have fled the moment we appeared in sight, have I turned my eyes towards my dogs to admire their attachment, and have felt a grateful affection toward them for pre- ferring our society to the liberty of other quadrupeds. Often, in the middle of the night, when all my people have been fast asleep around the fire, have I stood to contemplate these faithful animals lying by their side, and have learnt to esteem them for their social esteem to mankind. When wandering over pathless deserts, oppressed with vexation and distress at the conduct of my own men, I have turned to these as my only friends, and felt how much inferior to them was man when actuated only by selfish views. " The familiarity which subsists between this ani- mal and our own race is so common to almost every country of the globe, that any remark upon it must seem superfluous ; but I cannot avoid believing that it is the universality of the fact which prevents the greater part of mankind from reflecting duly on the subject. While almost every other quadruped fears man as its most formidable enemy, here is one which regards him as his companion, and follows him as his friend. We must not mistake the nature of the case : it is not because we train him to our use, and have made choice of him in preference to other animals, but because this particular species feels a natural desire to be useful to man, and from spontaneous impulse attaches itself to him. Were it not so, we should see in various countries an equal familiarity with various other quadrupeds, according to the habits, the taste, or the caprice of different nations. But everywhere it is the dog only takes delight in associating with us, in sharing our abode, and is even jealous that our attention should be bestowed on him alone ; it is he who knows us personally, watches for us, and warns us of danger. It is impossible for the naturalist, when taking a survey of the whole animal creation, not to feel a conviction that this friendship between two creatures so different from each other DOG. 297 must be the result of the laws of nature ; nor can the humane and feeling rnind avoid the belief that kind- ness to those animals from which he derives continued and essential assistance is part of his moral duty." The breeds of the dog, in a state of partial or com- plete domestication, are so numerous however, and the propensities of different breeds, and of different individuals of the same breed, are so varied, that there is no possibility of giving any thing like a general character of the race, while even a judicious selection of the tales of their biography would rill many volumes. It is impossible not to admire the sagacity and the strength of attachment which many animals of this genus evince ; and as they appear, when properly domesticated, to merge all their own attachments and interests in devotedness to the cause of their masters, it is exceedingly difficult to account for their conduct upon any of the known principles of animal physiology. That there is nothing at all approaching to what we call reason, or a process of judgment, as men judge of cause and effect, in the sagacity of dogs, is certain, because instances are recorded of the effects of their sagacity, which totally surpass all reason, and abso- lutely appear as if they were the results of some occult principle, to the nature of which we have no clue. The power of sensation in these animals, especially of the sense of smell in such of them as in a state of nature make use chiefly of that sense, in obtaining their prey, is perfectly wonderful ; and they appear to know not only the slot or scent left by an animal, •where there is no impression upon the grouud in the least cognisable by human senses ; but they appear to recognise a difference of scent, not only in different animals of the same species, but absolutely in different inanimate substances ; and what is more wonderful, they appear to know the direction in which that which they pursue or follow, has proceeded, even when it has long gone by. We have well authenticated in- stances of dogs having been carried within carriages, over long distances, where they had no means of examining a bit of the road ; and yet of their return- ing when liberated, with the most unerring certainty, to the places from which they were originally carried in this artificial manner. A dog too who has had any experience in following on the scent, will not continue for any length of time on the back scent, or direction opposite to that in which the chase is gone, but after a trial or two with his nose, will double round and follow the forward scent or direction which the animal has taken. This is, perhaps, the most extraordinary case of animal sensation witn which we are acquainted, and it shows how admirably nature can adapt the qualities of animals to the necessities of their modes of life ; and also how economical nature is in the dis- tribution of even these wonderful endowments. Dogs which find their prey by the sight never have this wonderful acuteness of smell ; and those which have this in perfection have not the powerful sight of those which are without it, neither are they, generally speak- ing, so swift-footed. But those which have the sense of smell most powerful arc, generally speaking, more persevering and staunch than the others, and can follow their game over longer distances, and also find it again much more readily in the case of losing it. Dogs are, generally speaking, social to some extent or other, even in those conditions which we may con- sider as more nearly approaching to a state of rude nature ; and, in the formation of their social unions, for the accomplishment of particular purposes, their instincts are not less wonderful than in the acuteness of their sense of smelling. We shall mention one instance of this, the authenticity of which may, we believe, be relied on ; though it is not easy to account for it upon any known principle either of instinct or of reason, or of that imaginary principle which they who seek to explain that in animals which is not explainable, are in the habit of gratuitously endowing them with. All attempts at explanation of this kind are unwise in principle and ineffective in practice ; and, therefore, attempting them does not admit of any defence on the score of sound judgment. In all parts of nature, in the vegetable and the mineral kingdoms as well as the animal, and even in the simplest substances, or at all events the most apparently simple substances which we meet with in those kingdoms, there are puzzles every bit as inexplicable as the keen senses and won- derful sagacity of the dog ; and we need not vex our- selves at being unable to explain the rationale of these upon any principles analogous to those of which we understand the working, until we have explained why every plant and every animal is, within certain limits, true to its specific type; and why every crystallisable mineral is faithful to the primary form of its crystal. Throughout the whole of nature, we know very little of the " whys " and " wherefores," and perhaps we should best consult our wisdom and our dignity if we made no attempts to waste our time in speculations in those departments of nature respecting which we must remain for ever ignorant. But to proceed to our anecdote, of which no explanation can, we believe, be given : — A gentleman residing in the county of Fife, and not very far from the city of St. Andrews, was in pos- session of a very fine Newfoundland dog, which was remarkable alike for its tractability and its trustworthi- ness. At two other points, each distant about a mile from each other, and at the same distance from this gentleman's mansion, there were two other dogs, of great power, but of less tractable breeds, than the Newfoundland one. One of these was a large mastiff, kept as a watch-dog by a farmer, and the other a staunch bull-dog that kept guard over the parish mill. As each of these three was lord-ascendant of all animals at his master's residence, they all had a good deal of aristocratic pride and pugnacity, so that two of them seldom met without attempting to settle their respective dignities by a wager of battle. The Newfoundland dog was of some service in the domestic arrangements, besides his guardianship of the house ; for every forenoon he was sent to the baker's shop in the village, about half a mile distant, with a towel containing money in the corner, and he returned with the value of the money in bread. There were many useless and not over civil curs in the vil- lage, as there are in too many villages throughout the country ; but in ordinary the haughty Newfoundland treated this ignoble race in that contemptuous style in which great dogs are wont to treat little ones. — When the dog returned from the baker's shop he used to be regularly served with his dinner, and went peaceably on house duty for the rest of the day. One day, however, he returned with his coat dir- tied and his ears scratched, having been subjected to a combined attack of the curs, while he had charge of his towel and bread, and so could not defend himself. Instead of waiting for his dinner as usual, he laid down his charge somewhat sulkily, and marched off; 298 DOG. and, upon looking after him, it was observed that he was crossing- the intervening hollow in a straight line for the house of the farmer, or rather on an embassy to the farmer's mastiff. The farmer's people noticed this unusual visit, and they were induced to notice it from its being a meeting of peace between those who had habitually been belligerents. After some inter- course of which no interpretation could be given, the two set off together in the direction of the mill ; and, having arrived there, they in brief space engaged the miller's bull-dog as an ally. The straight road to the village where the indignity had been offered to the Newfoundland doe passed immediately in front of that dog's master's house, but there was a more private and more circuitous road by the back of the mill. The three took this road, reached the village, scoured it in great wrath, putting to the tooth every cur they could get sight of; and having taken their revenge, and washed themselves in a ditch, they returned, each dog to the abode of his master ; and, when any two of them happened to meet after- wards, they displayed the same pugnacity as they had done previous to this joint expedition. It should seem that in this case there was a mere momentary concert for the accomplishment of one object among three dogs differing considerably in their habits, and that when this momentary purpose was accomplished, the wonted animosity of the three returned, and they fought as readily with each other as ever. But it docs not appear that all casual, or apparently casual interferences of dogs for the benefit of each other, pass off in this momentary way ; for there is another well authenticated anecdote of two dogs at Donaghadee, in which the instinctive daring of the one by the other caused a friendship, and as it should seem a kind of lamentation for the dead, after one of them had paid the debt of nature. This hap- pened while the government harbour or pier for the packets at Donaghadee was in the course of building, and it happened in the sight of several witnesses. — The one dog in this case also was a Newfoundland, and the other was a mastiff. They were both power- ful dogs ; and, though each was good natured when alone, they were very much in the habit of fighting when they met. One day they had a fierce and pro- longed battle on the pier, from the point of which they both fell into the sea, and, as the pier was long and steep, they had no means of escape but by swim- ming a considerable distance. Throwing water upon fighting dogs is an approved means of putting an end to their hostilities : and it is natural to suppose that two combatants of the same species tumbling them- selves into the sea would have the same effect. It had, and each began to make for the land as he best could. The Newfoundland being an excellent swim- mer very speedily gained the pier, on which he stood shaking himself; but at the same time watching the motions of his former antagonist, which, no swimmer, was struggling exhausted in the water, and just about to sink. In dashed the Newfoundland dog, took the other gently by the collar, kept his head above water, and brought him safely on shore. There was a pecu- liar kind of recognition between the two animals ; they never fought again, they were always together ; and when the Newfoundland dog had been accident- ally killed by the passage of a stone waggon on the railway over him, the other languished and evidently lamented for a long time. We must not wonder at this permanent attachment, apparent gratitude, and apparent memory of grief, because there are very many instances of dogs who have not only refused to quit the bodies of their human masters, but have laid themselves down on their graves, refusinsr all consolation and all nourish- ment, and actually continued there till they perished of hunger. Now, it' we find instances in which dogs have done this for human masters, or more strictly speaking human companions, we can hardly question its existence as between one dog and another, if the proper circumstances shall call it into exercise. The companionship which the dog feels for man is still part of the character of the animal as a dog , and, therefore, though we do not so well understand the manner in which it is brought about, we have every reason to believe that it must be stronger as between dog and dog, than as between a dog and any other animal. But the communications of animals with each other, and the means which social ones have of forming those connexions with each other which may be called simple attachments, as not being connected either with their feeding or with their physiology, are matters very difficult to be explained. Perhaps no description of the general character of any animal is more accurate than that of the dog by Buffon ; and therefore we shall prefer giving a por- tion of it in substance to any thing which we could originally write ; and we do this the more readily, that popular description is almost all that can be written, except as referring to particular species. The dog, independently of the beauty of his form, his vivacity, force, and swiftness, is possessed of all those internal qualifications that can conciliate the affections of man, and make the tyrant a protector. A natural share of courage, an angry and ferocious disposition, renders the dog in its savage state a for- midable enemy to all other animals : but these very readily give way to very different qualities in the domestic dog, whose only ambition seems the desire to please : he is seen to come crouching along, to lay his force, his courage, and all his useful talents at the feet of his master ; he waits his orders, to which he pays implicit obedience ; he consults his looks, and a single glance is sufficient to put him in motion ; he is more faithful even than the most boasted among men ; he is constant in his affections, friendly without interest, and grateful for the slightest favours ; much more mindful of benefits received, than injuries offered, he is not driven off by unkindness ; he still continues humble, submissive, and imploring ; his only hope to be serviceable, his only terror to displease ; he licks the hand that has been just lifted to strike him, and at last disarms resentment by submissive perseve- rance. More docile than man, more obedient than any other animal, he is not only instructed in a short time, but he also conforms to the dispositions and the man- ners of those who command him. He takes his tone from the house he inhabits ; like the rest of the domestics, he is disdainful among the great, and churlish among clowns. Always assiduous in serving his master, and only a friend to his friends, he is indifferent to all the rest, and declares himself openly against such as seem dependent like himself. He knows a begsrar by his clothes, by his voice, or his gestures, and forbids his approach. When at night the guard of the house is committed to his care, he seems proud of the charge ; he continues a watchful sentinel, he goes his rounds, scents strangers at a dis- DOG. 299 tance, and gives them warning of liis being on duty. It' they attempt to break in upon his territories, he becomes more fierce, flies at them, threatens, rights, and either conquers alone, or alarms them who have most interest iu coming to his assistance ; however, when he has conquered, he quietly reposes upon the spoil, and abstains from what he has deterred others from abusing ; giving thus at once a lesson of courage, temperance, and fidelity. From hence we see of what importance this animal is to us in a state of nature. Supposing, fora moment, that the species had not existed, how could man, without the assistance of the dog, have been able to conquer, tame, and reduce to servitude every other animal? How could he discover, trace, and destroy those that were noxious to him ? In order to be secure and become master of all animated nature, it was necessary for him to begin by making a friend of part of them ; to attach such of them to himself, by kindness and caresses, as seemed fittest for obe- dience and active pursuit. Thus the first art employed by man was, in conciliating the favour of the dog ; and the fruits of this art were, the conquest and peaceable possession of the earth. The generality of animals have greater agility, greater swiftness, and more formidable arms, from nature, than man ; their senses, and particularly that of smelling, are far more perfect : the having gained, therefore, a new assistant, particularly one whose scent is so exquisite as that of the dog, was the gain- ing a new sense, a new facultv, which before was wanting. The machines and instruments which we have imagined for perfecting the rest of the senses, do not approach to that already prepared by nature, by which we are enabled to find out every animal, though unseen, and thus destroy the noxious, and use the serviceable. The dog, thus useful in himself, taken into a parti- cipation of empire, exerts a degree of superiority over all animals that require human protection. The flock and the herd obey his voice more readily even than that of the shepherd or the herdsman ; he conducts them, guards them, keeps them from capriciously seeking danger, and their enemies he considers as his own. Nor is he less useful in the pursuit ; when the sound of the horn, or the voice of the huntsman, ealls him to the field, he testifies hi* pleasure by every little art, and pursues with perseverance those animals which, when taken, he must not expect to divide. The desire of hunting is, indeed, natural to him, as well as to his master, since war and the chase are the only employ of savages. All animals that live upon flesh hunt by nature ; the lion and the tiger, whose force is so great that they are sure to conquer, hunt alone and without art ; the wolf, the fox, and the wild dog, hunt in packs, assist each other, and partake the spoil. But when education has perfected this talent in the domestic dog, when he has been taught by man to repress his ardour, to measure his motions, and not to exhaust his force by too sudden an exer- tion of it, he then hunts with method, and always with success. Both the origin and the progressive history of the dog, are matters which defy all investigation ; neither can it be said whether all the varieties now existing are or are not from one original stock. Or even whether the wolf be not a closely allied species, and perhaps identically the same. It is useless, however, to enter upon any investigation upon this question ; for the data are too few for warranting a conclusion either one way or another. Dogs appear to be the most obedient of all animals, both to natural circum- stances and to artificial treatment ; and so there is no knowing how far the differences which are observed among them are owing to the one of those causes or to the other. Of those dogs which are left as it were in a state of nature, or which are not bred or trained in any particular way, there are even greater differences than there are among those which are trained and kept with care. So much is this the case, that those who are in the habit of travelling much in the wilder parts of the country, know the different districts as well from the appearance of the dogs as from any thing else. Dogs even appear to learn from the general man- ners of those with whom they associate, as may be observed even in common society. Dogs kept by the vicious, whether they are kept for fighting, poaching, or other ruffian practices, or not, are inva- riably vicious dogs ; and, on the other hand, dogs which live vuth persons of mild manners and regular habits, when not chained up, which is a species of slavery to which dogs are very adverse, are always mild. No doubt much depends upon the breed when in a state of domestication ; but there is a wonderful disposition to accommodate themselves to circum- stances, in the greater number of the race ; and when we refer to other countries in which dogs are either in a state of nature, or have been neglected and allowed to run wild, we find that they also par- take of the characters of the places where they reside. It is this readiness with which this genus of animals yield to every kind of circumstance, whether that circumstance tend to improvement or deteriora- tion, which renders the progressive history of the dog so utter an impossibility ; for though we meet with wild breeds in various parts of the world, which are savage in their dispositions, and exceedingly difficult to be tamed ; yet these are just as likely to be the descendants of races which were once tame, as the best bred dogs are to be the descendants of races once wild. The dog is at all events an old inhabitant of the world ; and perhaps there is no animal more gene- rally distributed. Whether dogs existed in a wild state at any period of European history we have not the means of ascertaining ; but it is certain that they were in Europe at times long gone by, when the state of the country was very different to what it is at present ; for their bones are found in those deposits which contain the remains of the rhinoceros, the tiger, and the hyaena ; and though we cannot form very correct notions of how animals not now found in any but warm countries should have once inha- bited both continental Europe and the islands, yet we have in India an example of the same races of animals living at least in the near vicinity of each other. But there are many links wanted in the chain before we can in a satisfactory manner connect this oldest epoch of canine story in Europe with the present history of the race. The uses oi' this race of animals are so well known, that it is needless to mention them ; but still it is doubtful whether they be turned to exactly the most profitable account ; and while the savage and his dog are much more nearly upon a par in point of under- standing, than any other man and any other animal, DOG. yet it is doubtful whether the dog has had his fair share of the advantages of civilisation, so as to be able adequately to perform his part in the labours of civil society. In the very lowest state of society (we speak of nations, and not of individuals or classes in the same nation,) the dog is, of course, a hunter for his master ; and in the forest, and even in the flood, the dog is by far the more independent and the more successful hunter of the two, and could subsist a good deal better without the man than the man could subsist without him. As society advances a little, the dog becomes an ani- mal of draught ; and we find him employed in this state by the people of the extreme north, both in Asia and in America ; and as those very northerly tribes are not exactly inhabitants either of the land or of the sea, but rather of the line where these meet, at least during the time that the snow is on the ground, they, of course, can make use only of an animal that can subsist upon such animal food as they can then obtain from below the ice. In some of the southern islands the dog is bred for another purpose. In New Zea- land, for instance, there are two species or varieties of dogs,— a large one, which is left free to seek his own food in the woods, as he best may, and a smaller one, which the natives keep in a state of domestica- tion. The large one howls at the approach of the New Zealanders ; and all dogs which are not recog- nised by man as associates in some way or other, growl, or howl and yelp, rather than bark as dogs do in a domestic state. This change of the voice of the dog in consequence of domestication, is an exceed- ingly curious matter ; but it is a fact, and barking is among dogs as much an effect of Civilisation, as correct language and eloquent speaking are among men. There is still a closer similarity. The style of the language, not the mere propriety of the words, but the tone in which they are uttered, is no bad index to the general character and disposition of human beings ; and so in like manner there is no better indication of the general character of a dog than his voice. The larger dog of New Zealand is not, however, useless to the inhabitants of that coun- try, for it is their principal animal food. Dogs are also eaten by many of the islanders in the Pacific Ocean ; and in China they are regularly fatted for the table, and their flesh sofd in the butcher's shops. It is also mentioned as an instance of the wholesomeness ol dogs' flesh, that the celebrated Captain Cook was mainly recovered from a very severe illness at sea, by the broth and flesh of a dog. Indeed, there is no reason why these animals shoulc not be cultivated as articles of food in every country It is a pretty general law in the wholesomeness ol animal substances, that if the labour of the animals is not too severe, so that their muscular fibres thereby rendered too rigid for mastication, their flesh is juicy and racy, and easy of digestion, very much in proportion as they are carnivorous. This holds especially in the case of gut-birds and gizzard-birdi among winged game , and even among the fishes, the few which eat vegetable matter are not nearly so goot or so wholesome as those which not only eat anima food, but eat one another. A cod, for instance, is very king of cannibals, and yet he is a most valuabl fish , and the prince of our river fishes, the salmon is so fond of eating up his smaller associates in th stream, that he may be caught by an imitation of on of them made of a bit of wood and painted. It pite, therefore, of all our prejudices, and prejudice )f some sort or other lies at the bottom of all our elf-inflicted miseries and privations — in spite of prejudice, it is really a grave question, and one in which we have the analogy of nature pointing to the affirmative, whether the dog ought not to be regularly )red and fed for the table, as a matter both of good aste and of sound domestic economy. As matters stand at present, it is pretty well understood that all dead dogs are not thrown away, but that not merely he humbler classes, who must be contented with a )enny pie or a twopenny sausage, but more dainty >alates, are, every day that the sun rises, fain to omfort their stomachs with some such viand as a ; savoury pate," containing a portion of a dog, and it may be with a portion of a cat, which cat Tiay have been doomed to suffer the torture of St. Bartholomew at the hands of some cat stealing and skinning hag. These matters are at least worthy of some consi- deration, the more so when we call to mind how comparatively few of the vast numbers of the young of those very fertile animals are brought up alive, and how many of them are cast away almost as soon as they are dropped, and thrown on laystalls and in ditches, and not unfrequently in the streets of the most crowded neighbourhoods, offending the eye, and tainting the atmosphere with corruption and disease. And it must be that the taint of such exhibitions fall more heavily than upon the mere atmosphere, because they display a recklessness for animal life which is more numerous in its instances, more loathsome in its displays, and every way more revolting than even that brutal cudgelling of donkeys which some of our legislators have seen meet to select as the special subject of their wisdom. We do not commend the beating of the animals in question, nor would we be understood as wishing to say anything in disparagement of that wisdom — that strong impulsive gravitation of sagacity by which any one subject is chosen in preference to another as the butt of experimental legislation. But, when we com- pare the two cases together, it is impossible not to see that there is an occasional attempt made to strain at the gnat and swallow the camel. The disregard of animal life, more especially canine life, which is produced by this incessant murder of the innocents, is much greater than that resulting from any other cause ; and it has this enormity in it, that it goes directly to corrupt the very young, and give them countenance and encouragement in the perpetration of cruelty, and of cruelty to that race of animals which, being more directly the associates of man than any other animals, should not, in a pet individual, or even in any dog considered as pro- perty, or of whom any one can say " my dog," and quote the adage, " Love me, love my dog," — not in any of these lights, but generally as a race, and because of the superior endowments with which, as a race, nature has furnished them, it is our first duty toward animated nature to foster and cherish them ; but, instead of this, we are strangely taught that it is matter of course, nay, matter of duty, to take them in their helpless state and drown them in cesspools or kennels, or batter them about in the street with more gratuitous cruelty than we would ever think of bat- tering that which never had any life. Any ignominy offered to the body of that which once was alive, whether the living thing is an elephant DOG. 301 or a gnat, or any thing within the possible range ot the scale of animated being, gives a taint to the mind of deeper enormity, because more direct and more lasting in its consequences than many are aware ot. The body of every animal is all that, as a substantive existence, is palpable to our senses ; in fact, it is the animal to our understanding ; for, though we see the action of lite in the living animal, we do not see the life itself ; therefore, we never can divest the body of an animal, or even a fragment of one, of that associa- tion with life which is grounded upon all that we can possibly observe. Wherefore, every indignity which is wantonly, and in the spirit of triumphing over it, offered to "even the mutilated fragment of an animal, tells as a step in cruelty towards the whole of ani- mated nature, and towards man himself among the rest. Even the boy who kicks about the head of a pullet, or the foot of a lamb, which has been thrown into the street as useless, is taking one step in cruelty ; and it only requires a sufficient number of steps, however small they are individually, to debase him to the commission of murder or parricide. As this question, or rather the many important <]uestious which this view of the subject opens up, are new, it may be necessary to caution the reader, who has been accustomed to only the common bio- graphical gossip, or the systematic dreams and con- jectures on the natural history of the dog, that this bears more directly on the spirit of the part of that history which will come vrithin the scope of reason and certainty, than anything else which we could say on the general subject ; while, in addition to this, it bears very strongly upon one of the most important questions in human conduct, both in an individual and a national point of view ; and we have taken it in conjunction with the cruelty practised towards the donkey tribe, in order that the ethical part may thereby be rendered more clear and more striking. In the first place, this cruelty is done to the animal in a state so young, that it can have done no harm, and might be urged on to do good by kind treatment ; whereas, in the harsh treatment of the donkey, there is generally some sort of plea of urging it on to speed, and therefore the cruelty here becomes cruelty onlv by being excessive ; whereas the other is en- tirely gratuitous cruelty in the very smallest atom of it. In the second place, the cruel treatment of the donkey presupposes that there is a feeling of the present usefulness of the animal ; and this, again, requires that the person who perpetrates this kind ot cruelty is more advanced in life, and also in vice, than the mere children who perpetrate that other cruelty, which societ}', with one consent, look upon us a very innocent matter of course. Now, there is always more harm done by corrupting the innocent, than by plunging those who arc already initiated a little deeper into vice. So, also, when we look at the youth, the infancy we may s-iy, of the puppies and kittens which are thus daily destroyed, we find that this tendency to disregard animal life, and therefore to treat animals, including human beings, with cruelty, operates against animals when they are in their most helpless, though, at the same time, their most interesting state. There is no question, therefore, that this wanton destruction, in their helpless days, of those animals which stand to man in a relation of companionship so much closer, and more nearly equal, than is found in any other case, must have the effect of producing indiffer- ence to human children ; and this is the gravamen of the evil, both in the conduct of the grown up, toward children, and in the conduct as between child and child. It is in early childhood, far more early than we are in the habit of supposing, that the die of human destiny is cast ; and if we habituate the young from their infancy to scenes of cruelty, and cases of uncalled for indignity offered even to the dead bodies of helpless and unoffending animals, we may rest assured that we are shaking with more perilous and certain destruction the two main pillars which uphold the fabric of a sound and wholesome population, than by any single perpetration by the random villains of mature age, which will occasionally spot and deform even the best societies. This must suffice for the moral argument, though it is eminently deserving of far more, and might be made the principal theme of as useful a book as ever was written by man. But we must shortly advert to our proper subject, the physiological view of the case, which is, however, inseparably connected with the moral one. As we have already seen, in our brief notice of the countries where dogs are found, they are distributed over the whole earth, from the equator to the thick- ribbed ice at the poles, and to the remotest isles of the ocean, often where there are no mammalia except themselves, except it may be some rats, or other murine animals ; and, though it is incidental, yet it is proper to add, as a corroboration of what we are about to state, that the incredible numbers, and the wonderfully rapid breeding of those small animals, offers another subject well worthy the attention and the profoundest examination of every one who wishes to look on the works of the Almighty with an eye of usefulness and gratitude. We have seen, also, that the dogs can accommodate themselves more com- pletely to circumstances than any other race, more completely than man himself. In, or nearly approach- ing to, a state of nature, they may be said to be tempered to every wind of heaven — proof to all temperatures — invincible by fatigue, and patient and enduring under hunger. They are, in short, the mammalia of the greatest labour ; and one little dog will perform greater feats in the sum total of activity, during a single day, than the strongest lion in the wilds of Africa could endure in a w"fcek. Besides, the foot of the dog is for the earth only, to run, to walk, to leap, or to unearth his prey, or dig, or otherwise trim his habitation. In point of fecundity, dogs are also exceedingly prolific, and they are no more seasonal in their breeding than the human race are, We have said that a litter consists of about a dozen sometimes, and there is no doubt that, with proper treatment, it might amount to this at all times, which might be averaged at something like at least a ten- fold increase in the year, after making ample allowance for contingencies. That there is purpose everywhere in nature, any one who is not grossly ignorant must admit. But, here is an animal, more completely distributed over all the earth, more completely adapted to all change of circumstances than any other creature upon the earth, endowed ,vith more sagacity than any other creature upon the earth, not excepting even man. himself, if he neglects the cultivation and use of his mind, and capable of breeding more rapidly than any other creature of the same size : — here is, in short the chief jewel in nature's living casket. Can we 302 DOG. suppose that there is no purpose here ? Is it con- sistent with any thing else which we see in nature, that that animal, which is endowed and furnished above all other animals, should be the only one which the Almighty has thus bountifully endowed and furnished, but all in vain ? It is impossible to come to any conclusion so absurd as this, and therefore we must look abroad in nature, and examine what purpose those animals are intended to serve in wild nature, or in countries which have all the richness of virgin soil. Then, if we are able to see our way clearly in this part of the inquiry, we have still another branch remaining, which is highly important, as tending to prove that usefulness to man forms part of the original design which runs through the whole system of nature : and, besides its value in a merely natural history point of view, it is a very strong collateral proof of the truth of the book of Revelation, because it shows that the dominion said to have been given to man is no emanation of human vanity, but a real declaration by Him who cannot lie : " God said, Let us make man in our image, after our . likeness : and let them have dominion over the fish of the sea, and over the fowl of the air, and over the cattle, and over all the earth, and over every creeping thing that creepeth upon the earth. So God created man in his own image, in the image of God created lie him ; male and female created he them. And God blessed them, and God said unto them, Be fruitful, and multiply, and replenish the earth, and subdue it : and have dominion over the fish of the sea, and over the fowl of the air, and over every Jiving thing that moveth upon the earth. And God .•said, Behold, I have given you every herb bearing seed, which is upon the face of all the earth, and «very tree in the which is the fruit of a tree yielding seed ; to you it shall be for meat. And to every beast of the earth, and to every fowl of the air, and to every . thing that creepeth upon the earth, wherein there is life, I have given every green herb for meat : and it was so. And God saw every thing that he had made, and behold, it was very good." Such is the original declaration ; and the benedic- tion of the whole being " very good" involves in it the notion of the general purpose and adaptation running through the whole, fitting all the individual parts for each other, and the aggregate for rational man, as the means of knowledge and the subject of enjoyment. From what we know of countries in a state of nature, we observe, that in them the working of nature is everywhere in excess ; they are clothed with thick forests, the action of which keeps up a continual evaporation and precipitating of moisture by the air ; and as the whole of the vegetation which results from this great energy of the powers of nature is adapted for being food to some living creature or other, the quantity of life existing in such countries is beyond what we can well imagine, if we did not actually see it. It is not the mere surface only which is inhabited, for the trees of the forests are tenanted to their very tops, not only with the smaller kinds of living creatures, but with tree birds and tree mammalia, up to the rnaccavv, which feeds on the topmost fruits, and the sloth, which keeps down the exuberance of the topmost leaves, clinging to the twigs, and back undermost, grazing against the sky, as if it were a sort of ruminating animal turned upside down. It would be impossible to enumerate all the details of this exuberance of nature in the early ages of countries, and in all probability before they became the abodes of the human race ; but we have, in those memorials which remain buried in the ground, the clearest evidence that such has been the state of many parts of the world in which the natural vegeta- tion has given place to that which man cultivates for his use ; and the elephant, the rhinoceros, the large species of stag, and those older animals of more singular forms, and some of them of more ample dimensions, together with those remains of plants which are buried in the soil, clearly show that, even to high latitudes, even the northern hemisphere, this vast exuberance of nature has at one time been general ; and, as the remains of man have never been met with in those sepulchres of the times of old, we may reasonably conclude that this state of things was actually anterior to the peopling of the several regions with human beings. In a state of things where production was so much in excess, it is natural to suppose that destruction must have been equally so, for the two go hand in hand ; and the excess of life is really an excess of change, the transference of organic matter from the body of one living creature to that of another. Now, as the earth can be cleared of animal matters only by the labours of animals which prey upon animal substances, and as the habit of the cat family is to lie in wait and prey chiefly upon living animals ; and further, as their structure adapts them rather for great momentary efforts than for continued exertion, they are fit only for keeping down the excess of living animals, and that only in particular situations. But, in such a state of things as that which we are considering, the number of dead animal substances with which the earth must have been strewed, and some of which must have been buried under the earth by the deposits left by the waters, there appears a very obvious necessity for a large supply and general distribution of those animals which belong to the dog tribe, and the other divisions of the great genus Cants, the fox, the hyaena, the jackall, and the wolf. We accordingly find that these animals have been very numerous in almost every part, at least of the eastern world, though some of them, as the hysna, have long perished from the northern parts, and others, as the wolf, are fast disappearing. But, when we take note of the places where these animals are still to be found, we perceive that they are, general!}' speaking, countries in which there is a strong action in nature, and a proneness to return to the wild state. We are, in the meantime, concerned only with the dog ; and the chief places where dogs are found in a wild state are those in which, if culture is even for a short time neglected, in consequence of hostile devastation or of any other cause, the surface is speedily overrun by thick forests or tangled jungles. Those places are India, some of the eastern isles, and many of those in the Pacific. — Every one who has at all attended to the subject must be aware how speedily every neglected spot of India, which is at all within the reach of the periodical rains, is converted into jungle. A single year suffices in many situations to bring a covering of bamboos at least sixty feet high ; and as the larger species of cats are adapted for acting on the margin, and in the open glades of the forests, where, though they require cover for their concealment, they also require scope for their priug, it follows that the beating of the forest must DOG. 303 be left to predator}' animals of different structure. So also those larger cats cannot prey on wide plains, be- cause they have no concealment in which they can lie in wait ; and, therefore, a race of animals to scour the grounds are there required, not only to clear away the decaying substances, but to keep down the num- bers of the browsing animals, and of those birds which seek their food upon the ground. In all such situa- tions \ve have the proper work cut out for the genus Cttnin, thouu'li. of course, the tribes of that genus are adapted to different haunts, and possess different habits. What they were original! y we do not exactly know ; but from their superior sagacity, and the ease and speed with which they adapt themselves to cir- cumstance-, it is easy to see that they are exactly the animals to conform their habits to every change of place, and thus to preserve their existence, after those races which, though more powerful in the individual animal, and also in the individual effort, are much less Capable of enduring changes. It. is farther worthy of remark, that animals of this tribe have greater adaptation to all varieties of prey, as v.eil as greater aptitude for all varieties of food, than any other of the predatory tribes ; thuir social habits, and the readiness with which they collect at the sound of each other's voices, make them a match in their collective capacity, for any animal which we could suppose to inhabit their common localities. These localities are the intermediate ones, neither the marshy banks of the water nor the bleak hills ; and as the more powerful of the pachydermatous animals, such as the elephant and the rhinoceros, are found in the marshes, which are also the resorts of the larger of the genus Box, the dog tribe can always muster in sufficient numbers to master any animal which they have in general to encounter, and as they have more staunchness than any other animals whatever, the killing of a portion of their numbers by the animal attacked, does not turn them from their purpose. Nor is their habit of miscellaneous feeding of less service to them. This Mjries in the several tribes, and also in the several varieties of the same tribe, or even with change of circumstances in the same indi- viduals ; but. generally speaking, they can eat that prey which they have previously killed, or they can, in case of necessity, eat the most offensive garbage ; and also, in case of emergency, subsist in whole or in part upon vegetable substances. They have also some skill in what we may call animal medicine ; for when a dog gels diseased either from improper food, or from a surfeit, to which latter he is often subject after lonir fasting, he knows as exactly the vegetable substance which will set him to rights, as a human gourmand of experience knows what to order from his apothecary under similar circumstances. It is in different parts of India chiefly that the dog is still found in what may be considered a perfectly wild state, or living in the woods toward the moun- tains, without any apparent disposition to approach the habitations of the human race ; and those which have this habit, are still very retired, so much so as to be not very often seen, though they are known to exist, and that in considerable numbers, all the way from Nepal to the southern heights, and probably to the extremity of India, in all situations where there is sufficient cover for them ; but though these dogs are well known, and have been seen and described by Europeans, more especially since Indian zoology has been so laudably and so successfully prosecuted by British officers, especially those at the out-posts, and detachment stations in the wilder parts of the country, still, with all the knowledge that has been acquired, it is impossible to say whether those dogs existed originally in the mountains and forests oi' India, or have been allowed to escape in the course of some of those wars by which that country has been so often wasted. We shall have occasion to mention the appearance of this race, when we come to give our list of the leading varieties, so that all we require to do here is to mention that no particular conclusion can be drawn from these regarding what may be the actual habits of dogs in a state of nature. There are oliier ownerless dogs in the Indian villages, and also in the towns, which resemble more in their manners those varieties which live in the service of man ; and these are more social than the dogs of the hill forests. They are advantageous rather than otherwise ; be- cause they come and assist the adjutants and other large birds in clearing away the refuse, which other- wise infects the air in an Indian town or village. In this operation they are assisted by the jackalls. which, thouuh they do not. make their appearance during the day, begin to yelp in the neighbouring thickets as the dn*k sets in ; and come during the night to perform their labours, which are far from being without their value. The circumstances now mentioned \\ith regard to India tend to show the natural uses of the dog in tropical climates; and this is about the utmost extent to which we can go on that part of the subject ; be- cause every where else the dog is to some extent or other associated with man, and made to render some sort of service at the bidding of his master. In the more thinly inhabited countries which are wooded, and consequently contain numbers of small quadru- peds, there are many of those half-domesticated dogs which seek their prey by ranging ownerless in the woods ; but, generally speaking, they are of the same variety with those that obey human masters. The islands where the larger breed of dogs is kept, or at least captured as game, are almost the only places, wit.li the exception of India, where the wild rangers of the woods and the domesticated ones are of different varieties; and, as the wild dogs there are sought after for food with nearly the same eatrerness as game is in this country, they may be considered as in part answering the purposes of flocks and herds to the inhabitants. In the rest of the world, the other members of the genus Cants come in the place of the wild dogs which have been mentioned ; and in the extreme north the foxes and wolves, are very abundant ; the latter espe- cially are described as being, in the Esquimaux conn- try, the determined and destructive enemies of those domestic dogs which are so eminently serviceable to the people there. In more advanced states of society the uses of dogs are so familiar to every one, that it is unneces- sary to repeat them ; but the probability is that enough is not made of the strength and power of enduring fatigue in those animals. It is true that they are used for drawing trucks and small carriages ; and though very many of them are in the hands of persons who do not treat them kindly, yet they have more apparent zeal in the performance of their work, and do more of it in proportion to their size, and the cost of their maintenance than any other of our working animals ; and they at the same time act as 804 DOG. guardians of property, when their masters have occa- sion to leave it with them. Considering these things, it would, perhaps, be desirable to pay a little more attention to the kind of work which dogs could be made to perform, and the best modes of training and applying them to the performance of it. We shall now give very short notices of the leading varieties. This is a part of the subject in which it is not pos- sible to be systematic, for those reasons which have been already explained, and therefore we shall take the grouping of M. F. Cuvier, which is founded chiefly upon the greater or less elongation of the muzele ; but there is little dependance to be placed on the accounts which authors give of the way in which the varieties have beeu produced, either by change of climate or otherwise. Dogs, of the first division, have the muzzle con- siderably elongated, and the capacity of the cranium comparatively small ; many of them are very hand- some in their forms ; but they are not accounted so intelligent as some of tiie others. Dogs, of the second division, have their muzzles shorter than those of the first, and the capacity of the cranium much larger in proportion ; among them are to be found the species which are most service- able to man, and we may mention the shepherd's dog as an instance. Those of the third division have the muzzle still shorter ; and they are, generally speaking, stouter jnade than any of the others, and some of them are more ferocious. The character on which these divisions are founded is a very imperfect one : and the varieties in each, in eome instances, differ more from each, both in appear- ance and in character, than those of the different divi- sions. It may generally be said that the long-nosed varieties bite by snapping, and give a very powerful bite from the length and quick motion of the jaw ; but they do not keep their hold ; that those of the third division bite by seizing and retaining their hold, and performing a good deal of their operations by shaking their prey, while they retain a firm hold with the teeth ; and those of the second division incline more to the one mode of biting or the other, according to circumstances. 1. LONG-MUZZLED DOGS. The species which are most nearly in a state of nature belong to this divi- sion, and we shall take them first in order. THE WILD DOG OF NEPAL (Canis primezvus). This variety, which was first accurately described by Mr. Hodgson, extends over a very large portion of India ; and as the country is inhabited by many races, it is known by different names in different districts. In Nepal and the adjoining countries where it is found upon all the lower ridges of the Himalaya, from the Sutledge to the Burhampootra, it is called Buansu ; in Bengal it is Dhok ; and with the Mahratlas of the Deccan, it is K»l&ur. Over so wide a range as fifteen hundred miles in latitude, and more than a thousand in longitude in some places, it must have conside- rable climatal differences ; and there seems also to be some slight difference in its appearance upon the elevated grounds, and in the valley of the Ganges ; but all its more essential characters are the same wherever it has been observed ; and one of these characters is peculiar, the want of the second tuber- culated tooth in the lower jaw. Mr. Hodgson is of opinion that this is the parent stock of all the domes- ticated dogs ; and it is for this reason that he has given it the name of primavus ; but the hypothesis is a mere assumption, which does not admit of proof, and therefore the name is somewhat objectionable. The chief climatal difference is that in the elevated and com- paratively cold country of Nepal, it has much thicker and stronger fur, and is darker in the colour than in the more southerly parts of India. This dog certainly belongs to the long-nosed divi- sion ; for the character of that division consists more in the compressed form and small capacity of the scull, than in the mere elongation of the muzzle. Its nose is not very sharp ; its eyes are obliquely set with round pupils, and brown irides. The ears are long, erect, and a little rounded at the tips. The body is rather slender, but deep in the chest ; and the legs are long, very strong, and rather thick ; the tail is tapering, and borne with no recurvature. The neck is long. The whole character has, indeed, a considerable resemblance to that of a Persian grey- hound, in a rude and savage state, and exposed to the vicissitudes of a very variable climate. The colour is, generally speaking, a sort of reddish brown, a little darker toward the tip of the tail, and also between the eyes and nose. These dogs prey equally during the night and during the day, but their chief dependence seems to be upon the scent : they hunt in small packs of eight or ten ; and when in pack they are described as giving tongue in a sharp savage bark, unlike that of any domesticated dog, or of the fox, or the jackall ; but when they pursue their prey singly, they only utter an occasional growl. They are animals of great vigour and perseverance, and seldom fail in running down antelopes, deer, and other swift-footed game. As we have already mentioned, this species is wild as well as fleet, and therefore it is seldom seen. When a pack are met with, they do not attack human beings, and thus they are quite harmless to the inha- bitants ; but when they are assailed, they defend themselves, and turn on their assailants with great courage and vigour. When old ones are taken they do not appear to be susceptible of acquaintance with mankind ; but when the young are reared in a kennel with other dogs, they recognise their masters and associates, and evince nearly the average intelligence of the usual sporting breeds which are used for run- ning down game. The Pariah dogs which we have mentioned as abounding in and about the villages, have sometimes been referred to this division ; but they have many more of the characters of the more capacious-headed dogs of the second division ; so that, though in some respects they stand intermediate between the present variety and the various bred dogs of India, it does not appear that these can be considered as bearing any general relationship to them, though it is not unlikely that there may be crosses and mongrel breeds. The Pariah dogs themselves are, indeed, a mongrel race ; and it cannot well be otherwise ; for they mix freely, and without quarrelling with the domestic dogs. All the native dogs of India, we may remark, appear to be different from any of the European breeds ; though among them there are hairless races something like those which are found in Egypt and the parts adjacent. THE MALAY DOG seems to be nothing else but the wild dog of India, farther changed by still greater difference of climate ; and as it is pretty generally ij >.i|li DOG. 305 understood tnat the eastern islands even as far as the Archipelagos of the central Pacific, it is highly pro- bable that the dogs there are still originally of the same variety. THK AUSTRALIAN DOG OR DINGO. This seems still, in its essential characters, to be the same dog ; and as there is no placental animal of nearly the same dimensions in Australia, and the Malays have long frequented the northern parts of that country, it has in ail probability been imported by them ; though The Australian Dog. as the natives of Australia had no memory or tradi- tion beyond their personal observation when they were first visited by Europeans, it is not at all likely that they could have remembered the importation, more especially as their topographical knowledge appears just as limited as their natural history. The following is the description of the Australian dog : the head is much elongated and compressed, and tapers abruptly towards the muzzle, having much the appearance of a fox, with short erect ears. In the general proportion of the body he resembles the shepherd's dog. His body is thick with hair ; his tail bushy ; the hair is of two sorts, one woolly and grey, the other silky and of a deep yellow. The colour is deepest on the top of the head, and on the upper parts of the neck and tail, and the back ; the under parts of the neck and tail are paler ; the muzzle and face and inner side of the hams are whitish. The tail has eighteen vertebrae (dogs in general have nine- teen). The length of the body from the point o the nose to the commencement of the tail is two feet five inches. This dog possesses great agility, and i full of courage ; when running he carries his head up and his tail raised or extended horizontally ; and he is very voracious, seizing upon every kind of anirna" food that comes in his way. According to the de- scription, the dingo is altogether rather smaller in size, shorter in the legs and neck, and by no means so fleet as the wild dog of India ; but still the differ- ences in these respects are not sufficient to refute the notion of both being originally the same race ; anc we may see why they should be different, both in appearance and character, when we reflect on the difference between the countries which they inhabit From the great numbers of deer, antelopes, jungle fowl, and game of all sorts, India is a remarkably gooc dogs' country ; and we have experimental proof in the fact of there being two irreclaimed races in sup- plement to all the tame ones. Australia, on the other NAT. HIST. — Vor,. II. land, is just as bad a dogs' country as we could well suppose. Most of the small animals are climbers and even a sort of fliers, or leapers a great way from. >ranch to branch by the help of the extended mem- )ranes attached to their legs ; they also live in hol- ow trees, and places where dogs cannot easily get at them ; and thus the only game which is left for the dogs is the kangaroo, which is a fleet jumping animal, iar from numerous, and capable of breaking "the skull of a dog by the stroke ot its immense claw, when it kicks out in running. These may be among the reasons why the dingoes were originally found almost wholly in attendance on the bivouacs of the natives ; and it also explains why this animal, which is said to have been a favourite with the poor natives, has be- come a notorious sheep biter, and even an enemy to domestic dogs, since sheep and other European ani- mals were introduced into the colony. On the first introduction of sheep into the highlands of Scotland, about the time when the old practice of honourable cow-stealing by the men began to fall off, the curs of many places became notorious sheep-stealers ; and there are perhaps no dogs which will not kill sheep when pressed for food, if they have not been taught the contrary. THE AFRICAN DOG. The native dogs, which are in a state of semi-domestication among the rude na- tions of Africa, appear to be of nearly the same race as those which have been already noticed, only by being more domesticated their colours are more vari- able. Their habits are not much better known than the general characters of the countries in which they reside. The following are some of the particulars which are detailed. The wild dogs of Lower Guinea go out to hunt in large packs, and when they meet with a lion, tiger, or elephant, in their course, they set upon him with great fury, and usually overcome him. In these encounters they often lose a number of their pack. They do little or no damage to the inhabitants. They are red-haired, have small slender bodies, and their tails turn up upon their backs. The wild dogs at the Cape of Good Hope also range in large packs, and clear the whole country where they abound of all the wild beasts, and even the domestic flocks belonging to the several districts. What they kill they carry to a place of rendezvous, but allow the Europeans and Hottentots, who follow them, to take what they think proper without resistance. The Hottentots eat the flesh they thus obtain, and the whites salt it for their slaves. SOOTH AMERICAN DOG. When America was first visited by Europeans, the Indians, both of the south and the north, were in possession of dogs in a half tamed state, and agreeing in many of their characters with those dogs of the eastern continent which have been described. Since then the numbers both of Indians and of dogs have been very much thinned in all the better known parts of the country ; but they are still to be met with, and in the wilder places where the Indians have retained their old habits, they are still in possession of the dogs. The South American dog resembles the wild dogs of India rather more than those of the Asiatic isles, of Australia, or of Africa. The muzzle is rather slen- der, the ears short and erect, and the hair pretty long, especially that on the tail. The prevailing colour is grey with a tinge of brown on the back, a yellowish tinge on the under part, and ochre-yellow spots on the flanks. In the South American forests, where U 306 DOG. peccaries and other small mammalia are plentiful, these dogs abound in the wild state, lodging during the day in burrows, which they dig in the ground, and seeking their food in the night. The old ones are not susceptible of attachment, but those which are taken young can be so far tamed that they are not disposed to join their fellows in the woods ; but they are not very sagacious or very tractable. The temp- tations are so great, owing to the abundance of food, and the close and cool cover during the burning heat of the day, in the thick forests of America, that it is difficult to keep any predatory animal out of these forests; and in Surinam and the adjacent settlements, where, in consequence of the number of rats that infest the sugar manufactories, cats are in much re- quest as domestic servants, the people are obliged to cut their ears close by the head in order to keep them at home. This has the desired effect both in the dry weather and in the rain, as the leaves and branches tickle the inside of the ear in the one case, and the rain gets into it in the other, both of which is very much disliked. NORTH AMERICAN DOG. This variety differs a little from the former; its expression is milder, and he is understood to have a keener scent, and to be more active in the chase, not being so much a dog of the woods as the South American, and being under the necessity of chasing swifter-footed game. From these varieties we can form some idea of a dog in something like a state of nature ; and it is worthy of remark, that though these dogs inhabit regions which are almost the opposites of each other in longitude, and are found both to the north and to the south of the equator, yet there is a very great family likeness among them ; so much, indeed, that we can hardly regard them as any thing else than climatal varieties. They are probably the most tropical of all the dogs in their present distribution ; though it is inferred from the shape of the bones in the fossil specimens which have been met with in Europe, that this description of dog, or a variety nearly approaching to it, was the one which lived coeval with the more powerful carnivorous animals, and the larger pachydermatous animals in that part of the world. This is rather a curious fact in natural history, and would lead us to infer that certain species or varieties of animals have, in the course of ages, belonged as much to eras in the history of the world as to geographical positions. Those which we have enumerated, with shades of difference in other localities, which would have been much too minute for popular purposes, are all the dogs which we consider as remaining in any thing like an original state, that is, a state in which their manners and their forms have not been to a great extent modified by the treatment which they nave received from their human masters. Or, if they are dogs which have been left to themselves, then they have been so left long enough for acquiring a far more uniform and unchangeable character in their localities than those dogs which are in a state of complete do- mestication. We shall now give a short enumeration of the leading domesticated ones which belong to the first division, or those with the elongated muzzle, anci diminished capacity of skull, acuteness of scent, and tractability and sagacity. There are two sub-divisions of these domestic varieties, one of which, the greyhound of the High- lands of Scotland, or, perhaps, the Albanian dog s the type; and another, of which the common grey- mund is typical. The chief distinctions of character )etween these are, that the first hunt their prey either singly or in packs, and can find it by the scent as well as the eye, though not very readily ; and the second lunt singly, arid find their prey almost exclusively by the eye. THE HIGHLAND GREYHOUND. This is a very jowerful dog, equally staunch and faithful; and, when he Scottish mountains swarmed with stags and roes, t was held in high estimation, as being capable of fol- owing the deer over surfaces top rough and fatiguing or the ordinary hound* of the low country. The The Highland Greyhound. general aspect of the Highland hound is commanding and fierce. His head is long, and muzzle rather sharp ; his ears pendulous, but not long ; his eyes large, keen, and penetrating, half concealed among the long, stiff, and bristly hair, with which his face is covered ; his body is very strong and muscular, deep chested, taper- ing towards the loins, and his back slightly arched ; his hind quarters are furnished with large prominent muscles, and his legs are long, strong-boned, and straight— a combination of qualities which gives him that speed and long duration in the chase for which he is so eminently distinguished. His hair is wiry and shaggy, of a reddish sand colour, mixed with white ; his tail is rough, which he carries somewhat in the manner of a staghound, but not quite so erect. This is the dog formerly used by the Highland chief- tains of Scotland in their grand hunting parties ; anil is, in all probability, the same noble dog used in the time of Ossian. The Scottish highland greyhound will either hunt in packs or singly. A remarkably fine and large dog of this description was a long time in the possession of Sir Walter Scott, bart., and was a most appropriate guardian for his unique and mag- nificent seat at Abbotsford. This splendid dog was presented to Sir Walter Scott, as a mark of the highest respect and esteem by the late chieftain, Macdonell of Glengarry. He preserved this race of dogs with much care ; and, in order to prevent the degeneracy which arises from consanguinity, he was in the habit of crossing the breed with the bloodhound from Cuba. D O and also with the shepherd's dog of the Pyrenees, which is distinguished for its size, beauty, and docility, Sir Walter Scott's Maida was the offspring of a sire of the latter species, and a dam of the Scottish high- land race, and certainly was one of the finest dogs ever seen in that country of the kind, not only on account of his symmetry of form and dignified aspect, but also from his extraordinary size and strength. This fine specimen of the dog probably brought on himself premature old age, by the excessive fatigue and exercise to which his natural ardour inclined him ; for he had the greatest pleasure in accompanying the common greyhounds ; and, although from his great size and strength, he was not at all adapted for cours- ing, yet he not (infrequently turned, and even ran down hares. Maida lies buried at the gate of Abbots- ford, which he long protected ; a grave stone is placed over him, with the figure of a dog cut on it by Mr. John Smith of Melrose, and bears the following- inscription : — Mairta, tu marmorea dormis sub imagine Maidse Ad januam domini. Sit tibi terra levis ! This powerful and splendid variety of dog was, in the olden time, employed in hunting the wolf, as well as the deer ; but the circumstances of the Scotch high- lands have changed, the wolf is no more, and the deer is so rare in most places that it ceases to be an object of sport, except to the few who have it as property. The stocking of the hills with sheep has also dislodged the deer, and rendered the deer dog a forbidden visitcr. Gentler sport has succeeded, and the soft sportsman of the south, with his pointer and his Joe Manton, have come instead of the driving dog and the daring high- lander. THE IRISH WOLF-HOUND. This race has also be- come nearly extinct, though there are still a few. It was, probably, larger than the highland greyhound, yet it still bore a considerable resemblance. The occupation of this variety is also gone ; for there are no deer inferee naturae in Ireland, and through some mismanagement, dreary and wasteful bogs have come in the stead of her forests, and the memorials of her deer must be sought under these wasteful and neg- lected accumulations. The following is probably the last general description, from nature, of the hound. In 1790, Mr. Lambert saw eight of them in the possession of Lord Altamont. They were the sole remnant of their race, which had then degenerated : the hair was short and smooth, brown and white, or black and white. One of the largest dogs was sixty- one inches long from the muzzle to the point of the tail, which latter was, of itself, seventeen inches and a half in length. The ears were six inches long and pendulous. The height from the toe to the top of the fore shoulders, twenty-eight inches and a half; the circumference of the breast thirty-five inches, and of the belly, twenty-six. All were good tempered ; and in former generations the race are said to have borne a great resemblance to the greyhound. If this latter fact is well authenticated, it throws some light upon the progressive history of this first division ; for the dogs of this subdivision stand something inter- mediate between the greyhounds, properly so called, and the wild dogs ; and so, if there is a return from the greyhound to the type of this subdivision, there might be a return in this to the type of the wild dog. There are dogs evidently resembling these in other countries, such as the large and rough greyhound of Russia, and that of the low lands of Scotland ; but G. 307 a particular account of them would not add much to the natural history of the genus. ALBANIAN DOG. If the wolf dogs of Ireland and the Scotch Highlands were celebrated in the middle ages, the Albanian dog was not less so in the classic times of old. They are the veritable hounds of the Goddess Diana ; and whatever it may make with reference to the goddess, it is good evidence of the excellence of the dog, that one presented by the immortal huntress to Procris, her favourite, was so staunch, that it never missed its prey. These appear to have been dogs in high estimation, through all the mountainous parts of Greece, and the breed is still pre- served, especially in the wild country after which the animal is named. This dog is about the size of a mastiff, his hair is of a very fine consistence, very thickly set, resembling fur, and of a long and silky texture, generally of different shades of brown ; his tail is long and bushy, which he carries somewhat in the manner of a Newfoundland dog ; his legs are strong, shorter, and with more bone than those of the greyhound, on which account he seems formed for strength rather than for excessive speed. The head and jaws are elongated, with the nose pointed, some- thing like that of the Greenland dog, but rather longer. This dog in former times was used in hunt- ing the wild boar and the wolf, as well as in fighting ; and was also reared in pastoral districts to protect their folds from wolves and thieves. We may natu- rally expect that there should be some climatal varie- ties in other parts of Europe of a dog which has been so long known to history. One of these probably is THE SPOTTED DOG, DALMATIAN, OR HUNGARIAN DOG. This is more an ornamental than a useful dog ; as it is soft in its manners and far from being intel- ligent ; but it is very handsome and very good- natured, and therefore it is much used as an atten- dant on carriages. It is so well known as to require no further description. In form, this dog bears a slight resemblance to some of the hounds, or the smooth pointers, but he has none of their valuable qualities. THE FRENCH MATIN. This dog is very different from the last mentioned, and possesses properties in some respects superior to any other dog of the divi- sion, on which account he is a great favourite in France, where his fidelity and his courage equally recommend him. His general characters are, — the head elongated, and the forehead flat ; the ears pen- dulous toward the tips, and similar to those of the greyhound ; the hair is generally of a yellowish fawn colour, with blackish, slate-coloured, oblique, and parallel indistinct rays all over the body. He is a very active and muscular dog, standing about two feet high, and three feet long. He is possessed of great courage, and displays much ferocity in attacking wild boars and wolves, in the hunting of which he is frequently used, and evinces great perseverance and eagerness in the chasing of them. The principal use of the matin in France is the tending of flocks, in which service he has all the qualities of the shepherd's dog of this country ; he is likewise employed as a house-dog, and is extremely assiduous and watchful in that capacity, protecting his master's property to the last extremity. In France he is held in higher estimation than any other of the watching or guard- ing dogs. But we must turn to the varieties which are still more deficient in scent and sagacity, but have that deficiency compensated by additional swiftness, great quickness of ear, and considerable acutencss of -308 DOG. vision. The general name of these is greyhounds, though that name is also given to the large and powerful wolf-dogs of the former subdivision, which have both the body and the muzzle much elongated, and are remarkable for their speed when on the chase. There is this difference between them, however, that the dogs formerly mentioned, are much stronger, do not, in general, run so swiftly, but can continue much longer. THE GREYHOUND. The greyhound is the very model of animals for symmetry ; and while his limbs are peculiarly muscular, though lightly made, there is no dog, and perhaps no animal, which has such elas- ticity of the spine. In many of the cat tribe that organ can be powerfully exerted for a short time ; and in some of the vivcrridce it acts powerfully for a continuation of leaps ; but in no animal do the spine and the limbs play so beautifully to each other as in the greyhound. The general character of the animal agrees with this elasticity of motion ; for there are few which are so actuated by fits and starts. The figure of the greyhound is so peculiar, so little likely to be confounded with that of any other dog, that it is quite unnecessary to go into any description of it. In ancient times the greyhound was reckoned a very valuable present, by the ladies especially, who regard- ed it as a very gratifying compliment. As far back as the time of King Canute, it was enacted by the forest laws, that no person should presume to keep a greyhound under the degree of a gentleman ; the sovereign regarding that animal as being peculiarly suited only to a person of elevated rank. In Charles the First's reign, greyhounds were held in very high estimation. The Isle of Dogs, which is now con- verted into the reservoir for the West India shipping, derives its name from being the receptacle of spaniels and greyhounds of Edward the Third ; and was select- ed from its contiguity to Waltham and the other royal forests. Much of the superiority of our present breed of greyhounds we owe to the judgment and perseve- rance of Earl Rivers and others. The Scotch Greyhound, which is in all probability the gazehound of England, is larger than the smooth greyhound of England and the warmer parts of Europe, and it is also of larger size, though not so elegant, and probably, for a short distance, not so fleet. It is generally understood that this was the dog employed in driving the deer in the moors of the south of Scot- land, and the north of England, at the time when that was so principal an occupation of the barons ; but in the pure state this hound is now comparatively scarce. The Turkish Greyhound is comparatively a small species with very little hair, so little that it does not hide the black skin. Its ears are not quite so pen- dent at the tips as those of the greyhound, properly so called ; and it is so insignificant in size, that it is only used as a pet. There is, however, a greyhound of the chase very much used in some places of the south-east of Europe ; and there is another in Persia, which resembles the wild dogs more than the wild dogs of Europe. The little Italian greyhound, which is very handsome, is used as a pet in many parts of Europe ; and it is a very lively little creature, but not remarkable either for attachment or sagacity. Such is a short outline of the leading varieties of dogs in the first or long-nosed division. II. DOGS WITH THE MUZZLE OF MEDIUM LENGTH. This section also admits of several subdivisions, according to the uses to which they are applied, and the properties which fit them for those uses. The principal subdivisions are hunting dogs, and dogs which, though they have a propensity for hunting, are more used for domestic purposes, or in some way to assist man in his labours. Of the hunting dogs there are two or three farther subdivisions, the chief of which are dogs which are used in the chase, and dogs which are used with the gun ; the last of which are most generally employed, except by those who sport on a large scale. The first are hounds of various descriptions ; the others are setters, spaniels, and a variety of others. We shall begin with THE BLOODHOUND. This hound is, or rather was — for in most European countries, at least, the breed is nearly extinct— the best on the scent of all the coursing dogs, and perhaps, also, the most staunch and persevering in pursuit of his game. When his human associates happened to be of mild dispositions and contented themselves with using him only in the legitimate way in which a sporting dog should be used, he was mild tempered and exceedingly tract- able ; but the very virtues of this dog were perverted through the vices of his masters ; and down to a comparatively recent period, and perhaps in some places even at the present time, the bloodhound has been trained to hunt human beings, and so add to the horrors of war, and the relentless cruelties of exter- mination. This dog has been used for these purposes in different parts of the world ; so that of the few which remain, there are several apparent varieties. At one period of the world's history, the commence- ment of which was in ancient times, bloodhounds were much used in Britain, and the breed is said to have been very superior. According to Strabo, British bloodhounds were used as auxiliaries in the wars of Gaul ; and there is no doubt that this prostitution of a noble animal to the basest of purposes, is the reason why, from time immemorial, this dog has had a bad name, and that " bloodhound" has been the appella- tion for such monsters of the human race, as could not be done justice to by any epithet drawn from the very worst vices of mankind. T:^ The Bloodhound. The following particulars will throw some light upon the character of an animal now little known, and also the uses to which this animal was applied : — In D O <>ld times, when possessions were insecure, the blood- hound was employed to trace out the thief, and recover the stolen goods ; so that he would swim a river in course of the pursuit, and immediately recover the footsteps of the culprit on the other side, never ceasing to follow him. until he was taken. Thus this animal is put under the protection of the most ancient laws, which enact, " that no person should stop or disturb a bloodhound or man passing with him, to follow thieves, or take malefactors." Theft was also so common in this island, that a person denying access to the hound was held participant in the crime. There is little doubt that it was known on the conti- nent, and also in England ; but the Scottish blood- hound, which is said to have been of large size and elegant proportions, was the most celebrated of all. Conrad Gcsner, who wrote nearly three hundred years ago, has preserved a figure of the Scottish blood- hound, which, he says, was transmitted to him by Henry Sinclair, Dean of Glasgow, a distinguished character of his era ; and Hector Boyce affirms, that it was of a red colour, or black with small spots. There was some difference between it and the English .bloodhound, though the properties of the latter were also eminent. Of the atrocities which were committed in ancient times by using bloodhounds against the human race, no accounts have come down to us ; but unfortunately we have specimen enough of what can be perpetrated in this way, in perhaps the blackest page in a volume of human history, no part of which is very bright. This is the history of the conduct of the Christian white men of Europe toward the unoffending red men of some parts of America, and, more so, to few of the hapless sons of Africa who had been captured and carried away to endure all the miseries of colonial slavery. Even the great Col u in bus himself, in order more completely to subdue the lawful owners of the island of Hayti or St. Domingo, carried out with him twenty-four bloodhounds as auxiliaries in his unjusti- fiable war upon the harmless and newly discovered natives. It is possible that all the occasions upon which bloodhounds have been used against negro slaves which have taken refuge in the mountains have not been recorded ; but a single specimen of their use by the French, some time previous to the island being wrested from their power, will suffice. In the last war carried on against the revolted negroes, or Maroons as they were called, they employed blood- hounds regularly trained against them, and they are even said to have had the barbarity of throwing their captives to the dogs to be devoured alive. In train- ing the hounds to this inhuman pursuit, we are told that they were confined in a kennel sparred like a caue, and sparingly supplied with the blood of other animals. The fit: lire of a negro in wicker work, stuffed with blood and entrails, was next provided as they grew a little older, and occasionally exhibited in the upper part of the cage : the dogs ferociously struggled against their confinement, and as their impatience increased, the effigy was brought nearer and nearer, while their usual subsistence underwent still greater diminution. At length it was resigned to them, and while voraciously tearing it up, and devouring the contents, the caresses of the keepers encouraged their perseverance. Thus their animosity to black men was excited in proportion to their attachment to the whites ; and they were sent out to the chase when their training was considered complete. The miscr- G- 309 able negro had no means of escape : he was either hunted down and torn to pieces, his wife and children sharing perhaps his calamity, or, if taking refuge on a tree, he was betrayed by the yelping of the bloodhounds into the power of his more savage pur- suers. This, however, was not the full extent of the evil. " But, indifferently kept in the neighbourhood of Cape Frai^ois, the dogs frequently broke loose, and infants were devoured in an instant from the public way. At other times they proceeded to the neighbouring woods, and surprising a harmless family of labourers at their simple meal, tore the babe from the breast of its mother, or devoured the whole party, and returned with their horrid jaws drenched in tiie gore of those who were acknowledged, even in the eyes of the French army, as innocent, and therefore permitted to furnish them with the produce of their labours." The stages of cruelty are progressive ; and those who delight in the torture of animals, w ill soon be in- different to the sufferings of mankind. Accordingly, the ruder nations universally enjoy ferocious contests, and are gratified with the sight of blood. Lions, tigers, and elephants, have been encouraged to tear each other in pieces, where mutual antipathies ceased to operate ; but to make use of that quality in the dog, which fits him especially for being the servant of man — to make use of that quality as an instrument of the most inhuman torture upon those who were already suffering misery enough, is beyond a parallel in the annals of atrocity. In hunting, which was his legitimate work in those days, when much of the country was in the condition of forest and chace, deer numerous, oxen few, and sheep not introduced in many places, the proper func- tion of the bloodhound was to find the game rather than to run it down ; and it was because he could find the scent or slot,e places where the country is grazed in breadth, because there he brings in the stray cattle with the same certainty and the same success as the shepherd's dog brings in the stray sheep. It is worthy of remark, that thosi; dogs which are useful in the management of domestic animals never attempt to make tneir attacks on a vital part, or on any part where a bite would be of serious injury. The mastiff flies at the throats of cattle, and the bull-dog attempts to seize them by the nose, and suffocate them, something in the same way as the jaguar is said to do with the wild cattle in South America ; but the curs, and other true cattle dogs, never attack any beast in front. They inva- riably snap at the heels, and pinch that part which answers to what is called the "funny bone "in the human elbow, and upon which even a moderate pressure with the fingers causes an acute momentary pain. One might very easily suppose that there is an original instinct for driving cattle without biting them in these dogs. When they snap at the heels, they seldom if ever draw blood ; and they snap at the one heel or the other, according to the direction in which they wish to turn the animal. Any one who has attended to the habits of animals must have observed that they always run upon that which gives them pain. If a 'horse 'in battle is slightly wounded by a bayonet, he will run upon it to his certain destruction ; and man himself is not exempted from this propensity ; for, if a bayonet once wounds a man in battle, so tar as to give him pain, he is almost certain of running himself through upon it. 318 DOG. How dogs become aware of this propensity in animals it is impossible for us to ascertain, because we do not know the notions by which animals are governed in their instincts. Indeed, the subject is one of those upon which all inquiry is vain, inasmuch as we are not in possession of anything similar, in our own experience, which we can compare to it. We know nothing experimentally of the operation of instinct unconnected with reason ; and, in conse- quence of this, we can never come to any satisfactory conclusion with regard to the motives or foundations of action in animals. But, notwithstanding this, the facts are undoubted ; and there is no fact better made out, or more wonderful in its cause, than the tact of these dogs in the driving of cattle. If they wish to turn the beast either to the right or the left, they pinch the heel only on that side towards which they wish to turn it, and the degree of their pinching is equal to the right of turning which they wish to effect. The beast also, itself, in so far seconds the action of the dog, because it brings round its head towards that side on which the pain is felt, and the joint action is sufficient to turn the beast fairly round, and force it off in the opposite direction before it has advanced more than its own length. If the object, however, is to drive the beast straight forward, the snapping is made alternately at both heels, and so long as it is continued, the beast advances with a yawing motion, until it is brought to the proper speed in the proper direction, and then the dog ceases to trouble it. This driving by the heels is a very valuable charac- ter in those dogs, inasmuch as it is quite impossible to drive cattle by attacking them in the head. In that case they offer battle, or, at all events, defensive hostilities, from their instinctive tendency to guard themselves from injury in that quarter. Hence, •when it is attempted to drive cattle by dogs which assail either the throat or the nose, the cattle are invariably driven wide, or separate from each other, and the labour of the dog is worse than useless. The cur is, probably, a variety, in part connected with, or derived from, the shepherd's dog ; but it dif- fers from the shepherd's dog in its being smooth in the hair, while the shepherd's dog is invariably shaggy. The legs are considerably longer in proportion to the size of his body, which is a good deal larger than that of the shepherd's dog, and is stronger in the make, with the ears half pricked, and a tail having a natural tendency to be short. Great attention is paid to the breeding of this dog in the north of England and southern counties of Scotland, as he is found to be a very useful and trusty servant ; and great care is also devoted by breaking him in for that purpose, i Being a very sagacious dog, he soon acquires a know- ; ledge of his master's fields, which he watches with the utmost vigilance, and is particularly attentive to the cattle that are in them, watching all their movements and regularly going his rounds ; and should any strange cattle appear among the herd, he will fly at them with great ferocity, and force them immediately to quit the pasture they are trespassing on. The general colour of this dog is black and white ; but it may occasionally be met with all black, and some- times it may be found all white. As, however, there is less attention paid in most places of the country, to the purity of this breed of dogs than to that of any other, the mongrels related to the curs, and 'used instead of them, are exceedingly numerous, so much j BO, indeed, that no account can be given of them. There are several breeds of dogs connected with those of the present division, and perhaps, also, with those of the former, which it may be necessary to notice. The principal of these are the following : — The Lurcher. This is a dog which hunts singly, and finds his game indiscriminately by the scent or the eye. It bears some slight resemblance to the hound, but its limbs are shorter and stronger in pro- portion ; its form is much less elegant, and its motions much more slow. The head is thicker and not so much pointed ; the ears are short, erect, and half pricked up; and the whole body is covered with coarse and shaggy hair, which is generally either of an iron-grey or a dull sand colour. This is a sneak- ing species of dog, and prone to lie in wait for his game ; and, therefore, he is a favourite dog with poachers, who employ him under cover of night, in the capture of hares and rabbits, and occasionally winged game. He is not much esteemed by regular sportsmen, and his very name is one of dishonour ; but within his sphere of action, the lurcher is a very sure and trust-worthy dog. The Leymmer is a dog whose memory is almost forgotten ; he was understood to be the produce of a cross between the greyhound and common hound, or talbot, partaking of the qualities of both with some additional ones of his own in supplement. Indeed, it almost invariably happens that, in cross breeds of dogs, if both parents are thoroughly bred, there are new and often very good qualities obtained by the cross. The leymaner possessed much of the swiftness of the grey- hound, together with a keen sense of smell, and he was, perhaps, more hardy than either of the breeds of which he was the joint production. It is, indeed, a very general case that cross-bred animals are much more hardy than either of the parents between which they are crosses ; and they are so whether they be what we call perfect animals, as is the case in most if not all of the mongrel breeds of dogs, or hybrids, which do not breed with each other, although they breed back to the pure blood, as is the case with the mule, between the horse and ass. This dog, notwith- standing his strength, his swiftness, and his power of endurance, had some of the stubbornness of the mule about him ; and it was necessary to confine him in a thong, and let him slip after the game had started, otherwise he would have run broad, and been quite ungovernable. The Tumbler. This is also a mongrel dog, though of what parentage is not very clearly ascertained. He is considerably less than the greyhound, with a long and lean body, and erect ears, but with the head more resembling the greyhound than that of the lurcher does. Still, however, his action is in many respects similar to that of the lurcher. He does not run his game fairly down in straight forward chase, like the greyhound, but practises arts, and shows a great deal of sagacity in catching it upon the double. In order to do so, and to betray the game into doubling nearer to him than it otherwise might, he counterfeits falling down or being crippled, until the game on the return of the double comes within his reach ; and then he pounces upon it with a single bound much greater than that of almost any other dog. It is from this habit of crouching and waiting the double, which he does with great dexterity, that he gets the name of tumbler ; and though he is far from being one of the most elegant or graceful dogs in coursing, he is by no means one of the least successful. DO The Turnspit. It is somewhat difficult to define to what other race of dogs these are most nearly allied. They are, perhaps, the least graceful of the whole tribe. Their bodies are long, their legs remarkably short, and they are prone to become exceedingly fat, as they are very lazy. They have, however, some good qvialities. The following are a few of their leading characters : — the head is rather large in pro-' portion to the size of his body : for the most part it has a peculiarity in the colour of the eyes, one of which has the iris of one eye white and the other black. The Turnspit is to be met with of all hues, but the most usual one is a kind of bluish-grey, spotted with black, — sometimes he is found of a slate colour. The shape of the head is something between that of the hound and pointer, with long ears. One variety of the Turnspit has straight legs. He is a bold, spirited, and vigilant little dog ; its services in Great Britain at one time were very much valued, but by the invention of machinery his work has been super- seded : he is, in consequence, becoming extremely scarce, and in all probability will very soon become extinct, although in Germany and France he is still used in the kitchen. Turnspits that take their hours for labour in regular rotation, know very well how to distinguish the roasting days from the rest ; and it is with some difficulty that they can be made to work on the latter, as if they had a notion that it was then a duty that they were not in duty bound to do, Several instances are recorded of dogs distinguishing the days of the week ; for in the neighbourhood of some towns there are dogs that regularly repair thither for market days, because they know that they can procure some booty then. The varieties of mongrel breeds in this division of dogs are, however, endless, so that it would be impos- sible to give any account of them, though they are all less or more attached to mankind, and capable of evincing affection in some way or other. But in towns, where the breeds of dogs are miscellaneous, these are apt to be mongrel curs, of very vicious cha- racter, which do not either benefit their keepers, or tend to place the race in a favourable point of view. III. SHORT-MUZZLED DOGS. The dogs of this division are different in their characters from those of either of the former ; and the differences are so striking, that it is by no means easy to suppose that they are of the same original race either with the dogs that have the elongated muzzle, or with those which have it of medium length. It is somewhat remark- able, that among dogs which are in what may be called a state of nature, there is no approximation to the short muzzle ; but the origin of this race is so obscure that nothing can be said respecting it with any certainty. They differ from each other according to the breeds and kinds as they are de- scribed ; but there are certain characters which belong in common to the whole of them. They have not the swift motion of the long-nosed dogs, neither have they the affectionate manners and playful dispositions of most of those of the second division ; and if the epithet "dog" is to be considered as a synonyme for surliness, this is the division of the canine race which are dogs by way of eminence ; and thev are the onlv ones to which the French, who are not" unhappy in their nomenclature, give the name of (lollies. These dogs are often faithful, vigorous pro- trctors of the property of their masters ; but they show no kindliness or affection. The larger ones are very 319 formidable, and even dangerous animals ; and the small ones, which are sometimes kept as pets, have little feeling of gratitude, and are always snappish to every body except those by whom they are immediately- fed ; and even to them the attachment does not appear to extend much beyond the selfish considera- tion of being fed. The dogs of this division are of no use whatever in the chace, or in any way in shooting or hunting ; they are not swift, their noses are very inferior, and their only good qualities are the strength, the severity of their bite, and the firmness with which they retain their hold. As used against domestic animals, in keeping them to their proper places, and turning them in any direction which may be wished, they are not efficient, neither are they safe. They do not drive the animal, as is the case with sheep-dogs and curs, but always attack it in front, attempting to seize its nose or tear its throat. They are, in fact, slaughter- ing or tearing dogs ; and they can be used only in those characters, and not in that of friends, companions, or assistants in any one labour. They are good only for an attack ; and, therefore, some of them have been employed in the most cruel and savage of those occupations of the profligate which are very absurdly named sports. It is a curious fact that dogs of this description should be known only in a state of domestication. — Some of the wild dogs are savage enough in their manners ; but there is none of them so savage, and we may add, none of them so destitute of what m'ght be called intellect in animals, as these short-nosed dogs. It therefore becomes a curious question how these races originated, and by what particular kind of treat- ment on the part of man, all the nobler qualities of the dog were merged in the single one of trustworthy ferociousness. Nor is it less a matter of curiosity, if we could unravel it, to ascertain why, along with this character, dogs of this division should have greater strength and more determined powers of endurance, than any of their more attractive brethren. This ques- tion we have unfortunately no means of solving ; be- cause, thousrh we know the origin of particular breeds we do not know the source whence they were derived, or the .means by which they have been made to differ so much from the rest. It is also singular that, along with this departure from the swift motions of dogs of the first class, and the endearing dispositions of dags of the second, there should be in this third one an alter- ation in the form of that most characteristic organ of a dog, the mouth. But such is the fact. These dogs do not bite with the same sharp snap as the others ; but in them all there is a disposition to hold on and to shake in pieces whatever they lay hold of. Their object, in fact, appears always to be the mangling and destruction of that on which their anger is directed, and though, in the performance of this, many of them are faithful, it is a faithfulness of ferocity. It is for this reason that they are chiefly employed as watch-dogs ; and it is their bad qualities, not their good ones, which are turned to account by their masters. They are, in short, dogs which are wanted only in vicious and depraved states of society ; and it does not reflect much credit upon civilised man that there should be no such dogs found among savage nations. If we could ascertain by what means the different breeds which form this section have been derived from the dogs which we know in wild nature, or whether they have been derived at all, 320 DOG. it would be a very curious inquiry, but, unfortunately, we have not sufficient data for such an investigation ; but, though we are not acquainted with the means by which mankind has been enabled so to degrade the more generous and noble qualities of the dog, as they are found a great deal in these races, yet there is no reason to doubt that the degradation is the result of human interference. Still, it is a curious matter, that not only the form of the head, and the shortness of the muzzle, but that the whole structure and appearance of the animals, which, judging from what we see in nature, are artificial, should have been altered so as to suit this apparently impressed and unnatural habit. We have no means of unravelling the mystery ; but really it is a curious matter, that, along with a cessation of swiftness in the chace, or play as a companion, there should have been imparted to those dogs a strength of body, and a shortness of muzzle, which are not possessed by any of the rest ; and these qualities are accompanied by a correspond- ing expression in the eye and hair of the animals. In the larger kinds, both eye and hair express ferocity, while in the smaller ones the expression is that of indifference or stupidity ; and both have the body much more thickly set, the chest wider, and the legs farther apart, than in those of either of the former divisions. There is also a distinctive character in the very covering. None of them have that smooth lengthened and curly hair which is so pretty in the smaller spaniels, and so graceful in the larger ones and the Newfoundland dogs ; neither have they that smoothness and gloss which we observe in the terriers (with the exception of the Scotch one), which, of all dogs of the former divisions, perhaps make the nearest approach to the present division, though they far excel them in sagacity. The charac- ter of the head is especially worthy of notice. In every dog of the two former divisions, of what breed soever he may be, and whether pure or mongrel, there is a pleasing expression in that part ; and even in those species, such as the greyhound, which are the least intelligent, there is always some speculation in the eye — something in the look of the animal, which speaks kindness and companionship ; but a dog of this short-nosed species, though he follows his master, feeds at his expense, and fights desperately for or with him, in good cause or in bad, merely glares upon the observer, and has no speculation in his eyes. His services as a guardian or a warrior may procure him respect ; but his own looks do not put in any thing like the same claim to kindness or society, which is solicited by a single glance from the other dogs. It is further to be remarked, that the
