"V^:S§^ CONDUCTED By J. C. LOUDON, F.L. G. & Z.S. MEMBER OF VARIOUS NATURAL HISTORY SOCIETIES CONTINENT. LONDON PRINTED FOR LONGMAN, REES, ORME, BROWN, GREEN, AND LONGMAN, PATET»NOSTER-ROW. 1834. LONDOT* ; Printed by A. Spottisvvoode, New-Street-Square. PREFACE In the course of the pubUcation of the present Volume, we have complied with the general request of our correspondents, and brought out the Magazine of Natural History monthly, at a re- duced price. This will enable us to give a more ready insertion to the articles of our contributors, and, we trust, will prompt them to continue and to increase their communications. In taking a general survey of the progress of Natural History during the past year, it is gratifying to observe the establishment of Natural History Societies, one after another, in many parts of the country. The British Association has given a grand stimulus to natural history pursuits ; and the personal intercourse, among naturalists, to which it has led, cannot fail to be highly favourable to science, and to good feeling among scientific men. By this means, also, the great object of science, viz., that of reducing it to practice, and rendering it available for the purposes of domestic and general improvement, is likely to be more immediately effected, than by the single influence of the press. The Natural History Societies of York, Newcastle upon Tyne, Worcester, Bristol, Bel- fast, and various other places, and the Entomological Society of London, are in a flourishing condition, and some of them have begun to publish volumes of their Transactions. Not only are new periodicals, devoted wholly or partly to natural history, being established in the metropolis, but also in the provinces. Among these deserve more especially to be mentioned, the EntomologiQal Magazine of London, and the Analyst of Worcester, The Continent of Europe, and more especially France and Ger- many, may be considered as having been long in advance of Britain in natural history pursuits. In the United States of America Natural History Societies are on the increase, and, what redounds much to the honour of a new country, The American Journal of Science (Silliman's) has been some years established, and continues to be respectably supported. There are societies in India which A 2 IV PREFACE. embrace natural history, in common with agriculture and garden- ing ; and a magazine has been commenced in Australia, in which natural history forms a prominent feature. So congenial are natural history pursuits to the human mind, and so much do they tend to the progress of civilisation, to in- creased domestic comfort, to peace between nations, and to human happiness, that to us it appears that it would be treason to nature to assert that this state of things will not be progressive, and will not go on increasing, till the condition of mankind every-where is improved to an extent of which we can at present form no idea. The more frequent appearance of this Magazine, as well as the considerable addition to the quantity of matter which will be given in the course of the year, demands corresponding exertions on the part of its Editor and Conductor ; but our readers and con- tributors may safely rely on these being made. In conclusion, we cordially thank our contributors for their past assistance, and earnestly invite them to continue to add to the common stock of knowledge through the medium of our pages. J. C. L.

It bears the closest resem- blance in its generic characters to ^ranea and Agelena; but differs in the eyes being nearly equal, in the length of the lip, and in the maxillae dilated at the apex : the palpi, too, differ considerably. From Clubiona, to which the ap- 12 Structure of seme of the Organs of a Spider. pearance of the maxillae would carry us, it is easily separable by the size of the eyes, the greater curvature of the rows, the lip, mandibles, and palpi, and, above all, the great length of the legs. It weaves, in the corners of unfrequented build- ings, a coarse irregular net with a recess, in which it awaits its unlucky prey. When at rest, it is usually supported by the legs, as represented by the outline p ; and then the tibiae, standing perpendicularly, present the appearance of a series of columns. In examining the insect minutely with a magnifying power of about 30, I was struck with the appearance presented by the hairs about the claws : these (the tip of one is seen at I) were very stiff, spine-like, and serrated along the edges, especially at the apical extremity (/), and nearly all arose from the under surface of the tarsus, enveloping the claws (seey). A single claw is figured at g, to show its form, and the pec- tinated teeth, thirteen or fourteen in number. I found that, along the whole legs, the hairs had more or less of this appearance (/); the serrae, however, diminishing in sharpness as I approached the body ; and among these, and lying close to the limb, were other finer downy hairs, from the sides of which proceeded alternate secondary hairs : a representation of one of these is given {n). The leg itself is shown at h and i, the latter being the tarsus. The discovery of these ano- malies (anomalies from anything I had before observed) in- duced me to examine other portions of the body ; and I found that some of the hairs, or rather spines, jutting out from the mandibles, had hairs differing from the former : from these innumerable little processes proceeded in a spiral direc- tion, as seen at Jc, being most strongly marked towards the tip of the spine. On the palpi the spines were merely ser- rated (see o), and only on the last three joints. I could not find any elsewhere. On the exterior portions of the maxillae, both kinds of hairs or spines were detected ; but along the inner edge, the tufts were found to have hairs quite flat and smooth until within a little of the apex, where they became plumed mostly on one side alone. The longer curved ones at the extremity of the maxilla were exactly similar : they are represented at e, and a few detached have this portion represented at m, A singular appearance also presented itself in a row of sixty-eight minute blunt teeth extending the whole length of the curved extremity of the maxilla: two of these, highly magnified, are shown at e\ I now recollected having once before observed teeth similarly situated, but I have for- gotten in what species; but it would seem likely, if detected in a few, to offer characters which might be appropriated for Illustrations in British Zoology, 13 generic distinctions ; at any rate, directing attention to these points may, perhaps, lead to some curious particulars in allied genera.

JD. Art. IV. Illustrations in British Zoology. By George John- ston M. D., Fellow of the Royal College of Surgeons of Edin- burgh. It is known to naturalists in general that Peyssonel, a phy- sician of Marseilles, who had travelled into Barbary and the Levant, was the first who distinctly published the animal nature of coral and of other lithophytes ; an opinion which, however true, gained no proselytes, until Abraham Trembley, a native of Geneva, had discovered the ii/ydra and its wonder- ful properties ; and Bernard de Jussieu and Ellis had demon- strated the existence of similar polypes in a great number of the lithophytes and zoophytes of the European shores. Since that time it has been believed that the little tenants of every zoophytical production, and all the little creatures which are found embedded in any common gelatinous mass, are po- lypes identical in structure, or nearly so, wdth the iiydra ; and, in this belief, many fleshy and fibrous productions which were known or imagined to be a common matrix of a numerous colony, were unhesitatingly arranged together in the same class, under the denomination of ^Icyonium. The structure of a few of these was ascertained, and seemed to confirm the propriety of this classification ; for there could be no doubt that the inhabitants of the ^Icyonium digitatum of Linnaeus were truly polypes ; and this was the best known and most easily examined species. Nor were the observations of 14r Illustrations in British Zoology : — Schlosser, or of Gaertner, whose name is immortalised by his work on seeds, sufficiently precise or distinctly announced to invalidate the received notions ; so that we may safely assert that, previously to the year 1815, no naturalist had even sus- pected that the individuals of the compound y^Icyonia pos- sessed any more complicated organisation than zoophytes in general. At the commencement of the year just mentioned, Savigny read to the French Institute a memoir which at once over- turned the established opinion, and which, while it forms, from the newness and importance of its matter, an epoch in the history of invertebrate animals, was also of great utility in directing the attention of naturalists to a department which had lain long uncultivated. By a series of the most delicate dissections, exhibited in engravings of equal delicacy and beauty, Savigny proved that very many of the compound -41cy6nia possessed inmates whose structure was such as to give them a claim to be enrolled in the class Mollusca : and the claim, although still disputed by many, has been allowed by the most illustrious naturalist of modern, perhaps of any, times. Savigny, at all events, showed that these minute creatures were organised very differently from the gelatinous polype or hydra ; and that, instead of a simple stomach for its only viscus, they had both thoracic and abdominal viscera, two separate apertures for these viscera, special organs of generation, and, in some, he thought, vessels and traces of a circulating system were by no means equivocal. Of the productions which were the subject of Savigny*s dissections and enquiries, there are several species in the British seas, which the reader will find enumerated in Dr. Fleming's history of our native animals; and I believe that the two to be figured for the present series of Illustrations are additions to his list. They had, when recent, so much resem- blance to a fig, that it was not doubted that one of them, at least, would prove to be identical with the y^lcyonium ficus of Ellis; but a closer examination showed the contrary. The naturalist, however, will not find, in our rude dissections and figures, the various organs exhibited with the clearness and definiteness they have in the engravings of Savigny : what the artist saw was correctly drawn, and, if they are found sufficient for specific discrimination, my object is accom- plished. It may merely be remarked, that, in one, I could perceive, in the large thoracic cavity, traces of a netlike structure on the walls, similar to some of those figured by Savigny, and sufficient to convince me of his general accuracy ; but they are not shown in our figure, as the appearances were ApUdiumfdllax, 15 not sufficiently distinct to be drawn by one unfamiliar with anatomical researches. 16. Apli'dium fa'llax. {fig. 4.) A, The common masses, of the natural size, on a small stone. B, A single animal removed, and much magnified. Description. Common body subglobose or papillary, gela- tinous, of a clear honey-yellow colour marked on the upper surface with white and brown specks from the contained animals; orifices circular, protuberant, plain, and entire. Animals distinct, scattered irregularly, each in its proper cell, perpendicular, about two lines long. Branchial aperture [a) divided into 6 equal short segments ; the sac (b) large, white, netted on the sides with minute square meshes, w^hich, how- ever, are very obscure ; oesophagus (c) narrow, entering late- rally at the upper side of the stomach {d\ which is large, yellowish brown, and mottled ; intestine {e) dark-coloured, wide, flexuose, recurved and winding up at the side of the branchial sac ; anal aperture {/) elongate, linear, entire, lateral, and near the mouth ; ovary [g) white, cellulose, at the base of the intestine, with a long white tubular canal running up and along the middle of the intestine, and terminating in the branchial cavity. Differs from Aplidium ficus in having the apertures in the common envelope entire, whereas, in the A. ficus they are distinctly cut into 6 equal rays. See Ellis, CoralL tab. 17. fig. b, c, d. Hab.

B, An individual removed and magnified. Description, Common body adherent by a broad base, knob-like or pear-shaped, nearly an inch high and half that in diameter, smooth, gelatinous, pellucid, of a straw-yellow colour tinted with brown, and marked with whitish streaks from the immersed animals. There are no fibres nor spicula to strengthen this common mass ; neither are there any visible orifices on the surface ; but, by ripping up the skin with a needle, the contained animals may be removed entire without difficulty. These are of a long threadlike shape, with a bulging and nutant head, scattered irregularly in the sub- stance of the jelly, in which they lie horizontally or nearly so. The length of a single individual is about four tenths of an inch. The mouth {a) is cut into six equal segments, and placed on the upper side of the large branchial sac (^), which Natural Productions of l^exden and its Neighbburhood, 1 7 is an oval bag filled, in the specimens examined, with innu- merable minute granules. When the animalcule was com- pressed between plates of glass, these granules escaped abundantly from the mouth, and from a prominent aperture a little below it on the side. The walls of the branchial sac are marked with several lines or plaits in a longitudinal direction ; but I saw no traces of any vascular network. On the inner side of the branchial sac there is an obscure ap- pearance of an intestine or vessel winding up it to end at the anal aperture {c) ; and near the base of the sac there is a con- siderable orange-coloured spot marked with longitudinal lines, and presumed to be the stomach {d). Immediately below this, the body is suddenly contracted into a very long and linear tail, as it may be called, in which, when compressed, we perceive a dark intestine-like mark, mottled with darker and lighter shades on each side, and a clear space between them ; but I cannot trace any distinct termination of these organs (which are the ovaries) in the branchial sac, although the shadings at the base of this part indicate the existence and situation of some distinct organs. This species has a great resemblance to Aplidium effusum of Savigny, but I cannot consider them identical. Hob, Berwick Bay, in deep water. Berxmck upon Tweed, Sept, 1833. Art. V. Remarks on the Natural Produelions of Lexden and its Neighbourhood* By J. G. (^TtfRct/*^*^-^ <^y%>^^ ) Our village stands on a gentle slope, at the foot of which runs the river Colne, winding its course through a picturesque valley, fertilising many rich and verdant meadows, and turning in its passage a considerable number of mills. Our soil is generally a light gravel, and so very dry, that our usual paths are passable even in the depth of winter, and we are thereby afforded facilities for the enjoyment of sylvan scenery which but few neighbourhoods possess. Just below the village, on the north-west side, is a con- siderable extent of spongy boggy soil, full of springs of un- common purity and strength, which, in the short space of a quarter of a mile, form a crystal stream sufficient to drive a corn mill, lately erected on the spot. This stream, which affords a supply of 400 gallons a minute, is not at all affected by the seasons, being equally strong in the driest and the most rainy weather. Our parish is particularly well wooded, producing many lofty oaks, elms, and alders ; and, consequently, we have mast Vol. VII. — No. .37. c 18 Na/ural Productions of Lexden of the birds common to wooded districts, and some which are by no means generally diffused. The boggy ground, in which the springs have their rise, is covered with low alders, and produces much that is interesting to the botanist. The raspberry (7i!iibus ida^^is) abounds in it, and, when the fruit is ripe, presents a temptation to venture on the soft and treacherous soil. In spring, the brilliant Chrysosplenium oppositifolium, with its yellow flowers and shinin<' foliage, forms large beds of green and gold ; the lowly wood sorrel (O'xalis Acetosella) hangs its pale and modest head beneath the mossy stumps of the decayed alders ; the beautiful ferns, Aspidium JFllix fce'mina and Aspidium di- latatum, luxuriate in the moisture and shade so congenial to them ; and the huge Carex paniculata rises to the height of four feet or more, and, with its long and elegant leaves issuing from the top of the stem, and reaching to the ground, might, by its exotic appearance, almost make you imagine that you had been suddenly transported into some tropical region, — " Where the huge palms extend their shady tops. And torrents foam o'er beds of golden sand." But the song of the nightingale in the adjoining copse, the peculiarly joyous and happy note of the willow wren (Cur- ruca Trochilus), the loud and familiar laugh of the wood- pecker (Picus viridis), and the often repeated note of the marsh tit (Parus palustris) are sounds which will soon awaken feelings inseparably connected with " our own, our native isle." Amongst the vernal plants of our district must not be omitted the sweet Adoxa Moschatellina, which rears its delicate flowers on the moss-grown bank of many a shady hedgerow ; a mild and certain liarbinger of sunny days to come. On the dry banks we have Jasione montana and the diminutive yet elegant Ornithopus perpusillus. Our woods abound with the anemone and the hyacinth (Anemone ne- morosa and »Scilla niitans), and our river banks are clothed with the beautiful spikes of Z/ythrum Salicaria, the unassuming Scutellaria galericulata, and Cardamine amara with its bright purple anthers. From the beginning of autumn to the end of the year, we see on the borders of our streams that graceful little bird the grey wagtail (Afotacilla Boarula) taking its insect prey among the stones in the shallow water ; and, in the depth of winter, the siskin (Pringilla ASpinus) abounds on the lofty alders, the seeds of which afford it acceptable food. The brilliant kingfisher (^Icedo I'spida) is almost constantly to be seen skimming over the surface of our waters, or seated on and its Neishhourhood, 1 9 "to a solitary pile or naked branch, patiently watching [IV. 450.] for its finny prey, while its glossy and radiant plumage is strongly contrasted with the sober dress of the skulking moorhen (Gallinula chloropus) which is flirting up its tail amongst the sedges hard by. We now and then see the kestrel (Falco 2mnunculus), the sparrowhawk (^uteo ^isus), and the hobby* (Falco Subbuteo); and our ears are often assailed, in the stillness of the night, by the clear and plaintive hooting of the brown owl (^Strix stridula), and the hoarse scream of its congener, the white owl (»Strix flammea). The nuthatch (.Sitta europae^a) utters its shrill and frequent cry, " wit, wit, wit," in our groves ; while the notes of the jay, the cuckoo, the turtle dove, and the mingled melody of a host of summer visiters, " aid the full concert," and form together a chorus which, combined with the usual scenery around, must move to ecstasy every heart that is capable of any degree of sensibility, and which ought to engage the breast in the adoration of Him who has given us all these things richly to enjoy. Our streams afford a considerable variety of fish, but to these I have paid little attention; for, even in this sequestered spot, " far from the noise, the hum, the shock of men," the cares of life will intrude, to the exclusion of those pursuits of nature which console in adversity, and render prosperity doubly delightful. I have sometimes been much gratified in observing that elegant little animal, the water shrew (^Sorex f()diens), diving and sporting under a little waterfall in one of our groves : it is one of the prettiest of our few quadrupeds, and is an animal which appears to have attracted but little notice. We have all that can be desired in a country village, and whether our lovely scenes be visited in the glorious spring, when morning puts forth its melody from grove and park and verdant field, or in the silent and mellow autumn, when the cool air breathes vigour and health to the frame, and the brilliant dews bespangle the mossy turf, now strewed with many a yellow leaf, they cannot fail to delight and exalt the soul of every rational lover of the beauties of nature. Lexderiy near Colchester^ \0 mo, {October'\ ^% 1833. ♦ A beautiful specimen of this bird was shot here last year by my much valued friend, Henry Doubleday of Epping, who, by his unwearied assi- duity and acute observation, has done much to promote a knowledge of the ornithology of our island.

On the Altitude of the Habitats of Plants in Cumber- landf with Localities of the rarer Mountain Species. By Mr. Hkwett Watson. Often as the county of Cumberland has been traversed by botanists, we are, nevertheless, yet very imperfectly ac- quainted with the stations of its rarer plants ; and there is, perhaps, not another county of England in regard to the botanical productions of which there are so many errors in print. Under these circumstances, I need scarcely apologise for submitting some observations and discoveries, made during a month's residence at Keswick, in May and June of 1833. This county is so constantly visited by the students in every department of natural history, that there will doubtless be some, among the readers of this Magazine, to whom the fol- lowing notices will be useful. My attention was principally directed towards the influence of height in changing the vege- table productions ; and, taking the highest stations at which particular species were observed, they may be arranged in steps of 500 ft., as follows ; but Scawfell Pikes, the highest hill of the county, being only 3166 ft., the first step in our descent will be a shorter one. The names accord with those of Hooker's British Flora. 1. Between 3000 ft. and 3160 ft. — O'xalis Acetosella, Ceras- tium viscosum, ^Saxifraga stellaris, Galium saxatile.

Between 1000 ft. arid 1500 ft. — We begin to seethe oak, ash, holly, and other trees, with a large addition of smaller species ; but it does not appear to be worth while for us to carry these lists below 1500 ft., since they would become more long than interesting as we descend to the low grounds. All these species descend to the low grounds about the lakes, except the following, the inferior limit of which appears to be at or about the heights added to their names : — iSaxi- fraga stellaris, 500 ft. ; »Salix herbacea, 2400 ft.; ^'mpetrum nigrum, Carex rigida, 2200 ft. ; Alchemilla alpina, 400 ft. to 600 ft.; Rhodiola rosea, 700 ft.; katice Armeria, about lOOOft. or 1200 ft.; Thalictrum alpinum, probably 1200 ft.; Coch- learia danica ; Epilobium «lsinif61ium, 700 ft. ; Oxyria reni- formis, 450 ft. Silene acaulis and iSaxifraga oppositif61ia were only seen in one station, and are fixed at about 2000 ft. by guess. Juncus triglumis and y4'rbutus UVa ursi were also seen in only one station, not actually measured. The lake at Kes- wick is estimated to be 228 ft. above the sea ; that of Thirl- mere is nearly 500 ft. All the other species were seen at or nearly on the level of one of these lakes. The early period at which the hills were visited would no doubt prevent my seeing all the species towards their summits, in the hollows near to which some patches of snow still lingered at the end of May, but quite disappeared before the second week of June. Excluding the ferns, we have, above 3000 ft., only 13 species ; between 2000 ft. and 3000 ft., 53 species ; and be- tween 1000 ft. and 2000 ft. there were 150, or more. Now, by observations in the highlands of Scotland last autumn (see Edinburgh New Philosophical Journal^ No. 28.), there are at these heights on the Scottish mountains, 80, 183, and 273 species. The small extent of surface elevated above 1000 ft. or 1500 ft. in the county of Cumberland, the dryness of the c 3 22 Altitude of Habitats of Plants in Cumberland, mountain summits, and the comparative paucity of elevated valleys, deep chasms, and rocky precipices, will no doubt ex- plain the numerical deficiency in its mountain flora. Up to 1000 ft. the vegetation of Cumberland is superior to that of the Scottish highlands. Above 2000 ft. the species are not only fewer, but, with all the advantage of a more southern latitude, they commonly fail much earlier as we ascend the hills. The average heights to which the species mentioned in the preced- ing lists were observed to attain in the highlands are, for the first (or those exceeding 3000 ft. in Cumberland), 3900 ft. ; for the second, 3200 ft. ; for the third, 2900 ft. ; for the fourth, 2400 ft. By average height is meant the mean obtained by dividing the sum of the highest stations observed in Scotland by the number of species. Mr. Winch, to whom we are indebted for the fullest and most accurate lists of species and botanical notices for the county of Cumberland, has very recently printed a thin quarto pamphlet of Contributions to the Flora of Cwnberland, in which are enumerated all except the commoner species said to have been found in the county ; but, from the author's remarks, it is pretty evident that many stations published on the authority of the late Mr. Hutton are errors, if not deserving of a harsher designation. Though I have verified many of the stations given by Winch, it is unnecessary to repeat them here ; and I shall, therefore, confine myself to those not included in his Contributions^ and mention only the mountain species ; at least with a very few exceptions. Circae^a alpina. Between the Great Wood and Falcon Crag, &c. — Galium boreale. In plenty on the east side of Derwent- water. — Alcliemilla alpina. Particularly plentiful about the Scawfell group of hills, as well as on the hills in crossing from the Vale of Newlands to Borrodale. — Lobelm Dortmann«. Watendlath Tarn, and the small tarn among the hills above it. In most of the lakes. — Fiola Idtea. Between Castlerig and Armboth, and on the north side of Latrigg. — Hibes petrae^um.

Black Rocks of Great End abundantly, and other hills. — S. oppositifolia. Black rocks of Great End. The Black Rocks were so called by my guide. They are the walls of a deep ravine crossed in ascending direct to the sum- mit of Scawfell Pikes from Styehead Tarn, keeping the Wast- dale side of Great End, instead of the usual ascent by the upper tarn. They are near to, but not in, the Screes, where this species has been before found. — S. ^ypnoides. Helvel- lyn, Great End, Grange, &c. — Silene acaulis. Black Rocks of Great End. Not in Winch's list. — i^ubus saxatilis. Hills between Thirlmere and Derwentvvater. — Potentilla alpestris. On the steep rocks in ascending from the Vale of Newlands, over Grange Fell to Borrodale. Not in Winch's list. — Thalictrum alpinum. Ascending from Styehead Tarn to Sprinkling Tarn, but nearer to the latter; also ascending from the Black Rocks of Great End to Scawfell Pikes.

That true and elegant naturalist, Hurdis (an Oxonian), was he who said, — " Not a tree, A plant, a leaf, a blossom, but contains A folio volume; " and the proverbiality his saying has attained proves that the truth of its sentiment is generally felt. Mr. Baxter con- tributes not a little to illustrate its truth, not only in the above communication, but in the cheap and excellent periodical now in the course of publication, entitled Figures and Descriptions of one Species in a Genus of the Flowering Plants of Britain, In that work, a plurality of associations are drawn together and connected with each of the plants figured, and among these associations, not rarely a notice, from Mr. Baxter, of the species of fungus which have been found to inhabit the plants' leaves and herbage, is supplied. — J. D. The common Berberry (Berber is vulgaris L.) is perfectly harm- less to the Crops of Wheat which may grow near it. (VI. 367.) — To Mr. Babington*s pertinent practical fact (VI. 367.), illustrative of this assertion, I would add, that the parasitic fungus which diseases the leaves of the berberry is ^cidiuni Berberidis Persoon, and is in species and genus most distinct from the parasitic fungus, Puccini« Graminis Persoon, which is frequently found infesting the herbage of crops of wheat. A figure of ^cidium Berberidis is given in Loudon's Ency- clopcedia of Plants, p. 1045. No. 16676*. ; and one of Pucciniflj Graminis in p. 104-7. No. 16710. In hedgerows around corn fields in some neighbourhoods, plants of the berberry are not rare (by Shaker's Lane, near Bury St. Edmunds, as one in- stance) ; and it is probable that the charging on the berberry the diseasing of the wheat, or other corn, which has grown near it, has arisen from the likely case of the berberry being infested with its parasitic fungus, the ^cidium Berberidis Pers., at the Pucbides in the Transition Rocks of North America. 27 time the herbage of the wheat has been infested with its para- sitic fungus, the Puccinia Graminis ; a coincidence which, it is presumed, ought rather to be interpreted as pointing to certain foregone conditions of the atmosphere or soil, which promoted the growth and multiplication of the respective funguses con- temporaneously, each in its own appropriate soil, the leaves or herbage of the kind of plant in and on which it flourishes. That the fungus of the leaves of berberry can grow on the herbage of wheat, or the fungus of the herbage of wheat on the leaves of berberry, is an idea which the concUisions of science wholly repudiate. The first origin of the funguses, and their appointed agency, must be deemed identical, in time and source, with those of the largest of plants. — J. Z). Art. VIII. A Description of a Fossil Vegetable of the Family Fu- coides in the 2\ansition Rocks of North America^ and some Considerations in Geology connected with it. By R. C. Taylor, Esq. The accompanying drawing represents an interesting fossil which abounds in certain parts of the transition series in Pennsylvania. This plant was noticed, for the first time, in 1831, under the name of Fucoides alleghaniensis, by Dr. Harlan, in the Journal of the Academy of Natural Sciences of Philadelphia. Dr. Harlan's description of this fossil jFWcus is so applicable to the specimen before me, that I shall take the liberty of con- densing his account. " It presents one of the richest spe- cimens of vegetable organic remains that have hitherto come under my notice. Not only is the surface of the stone crowded with the forms of this plant, but they lie upon each other three or four layers deep, as is demonstrated by a hori- zontal fracture. They project in bold relief from the surface, with their distal extremities disposed in every direction ; they appear to have been of different ages, and vary in size, accordingly, from 2 in. to 5 in. in length, the largest being eight tenths of an inch in thickness. In breadth they vary from one to five tenths of an inch ; they are generally gently arched from the base towards the apex, and more or less recurved at top ; in every instance the apex is curved downwards, and sinks into the stone. The superior surface of both the stalk and branches is cylindrical, transversely wrinkled by irregular channels, and marked by a longitudinal and depressed line. The digitations or branches are all com- pressed laterally as well as the stalk, and are flisciculated or 28 Fucoides in the Transition Rocks closely applied side by side at the commencement, and gra- dually diverge towards their distal extremities. " In every case the stalks divide into two or more branches ; the latter are more or less wrinkled, apparently according to age, the rugae being more or less obsolete in the largest, pro- foundly developed in the smaller or younger specimens. The plants are fractured in many places and in various directions; but the fractured portions do not display any evidence of organisation ; nor is there any appearance of leaves, nervures, or fructification." I believe that a fossil of this description has not been noticed in any part of the transition series in Great Britain ; yet, as some traces may be discovered through the aid afforded by an accurate illustration, I am induced to transmit some further notice of this fossil plant and of its geological position. Mr. De la Beche enumerates two or three species of Fu- coides in the grauwacke group of Europe. How near they may approach to the fossil which is so strikingly character- istic of a part of the same group in North America, I have no present means of ascertaining. The two species found in the transition limestone of Canada are dissimilar to the Fucoides alleghaniensis. The aggregate thickness of the grauwacke group is enor- mous in Pennsylvania; its breadth being about 120 miles, and its stratification being inclined at a very high angle, and often approaching to verticality, it is not improbable that the entire mass averages forty-five degrees. I have examined a large portion of this in detail, and have constructed a transverse section of about seventy miles, from which it appears that in about half this breadth the inclination of the rocks is towards the Alleghany chain, and in the other portion it is reversed. On the details of the subordinate portions of this group it is not my intention to enlarge. It is sufficient to observe, gene- rally, that they consist of arenaceous, slaty, and limestone rocks, subdivided into innumerable varieties of siliceous and argillaceous beds, conglomerates, shales, clays, marbles, flinty slate and flinty limestone ; and include numerous coal seams, both of anthracite and of the quality which may be termed bituminous anthracite, and large deposits of iron, both argil- laceous and haematitic. The surface of this region is broken into an infinite number of sandstone ridges and limestone valleys, all running parallel with the mountain chain of the Alleghany. These ridges are generally 700 or 800 feet above the valleys, and are incapable of cultivation. Thev are covered. of North America. 29 to the thickness of from 10 to 100 feet, with huge blocks of sandstone. Upon their steep sides few traces of vegetable soil exist ; yet the oak, the chestnut, the pines, and several other trees, Iiave obtained a firm footing, and have extended over the loftiest crests. Embarrassed with this accumulation of debris, the geologist seeks, almost in vain, for some exposed face, some unencumbered surface, to determine the arrange- ment and structure of these vast and singularly prolonged masses. He finds as much difficulty in viewing the details of their geological features, as in obtaining, from amidst the ancient forests which overshadow them, an uninterrupted view of the wide-spread landscape beneath his feet. I have observed Fucoides alleghaniensis, at points 150 miles remote from each other, in the sandstone ridges that occur parallel with the eastern side of the Alleghany Mountains; but nothing resembling them can be detected in the intermediate limestone valleys. The subject of my sketch {Jig> 6.) was derived from the vicinity of this place [Lewistown], on the banks of the Juniata River, and in the same district from which Dr. Harlan's specimen was procured. Detached fragments, rolled from the mountains, and fallen slabs, exhi- biting fine specimens of this fossil, are not unfrequently met with amidst the talus of the ridges ; but it is only very recently that thfe beds in which it occurs in situ came under my observ- ation. Under the conviction that these vegetable strata have hitherto escaped geological notice, I' proceed to detail some circumstances relating to their position. After passing Lewistown, the Juniata flows easterly, for 30 Fucoides in the Transition Rocks about six miles, through " the Narrows;" that is, in a deep narrow trough between the two sandstone ridges of Shade Mountain and Black Log Mountain ; having, for the most part, barely space for its channel. The great western turn- pike road and the Pennsylvania Canal also pass through this ravine ; being, for some distance, excavated out of the base of the northern ridge, called Shade Mountain. In consequence of these public works, many of the inferior strata are here exposed ; and although, in the aggregate, they do not com- prise a thirtieth part of the entire elevation, they are highly interesting, in displaying beds of fossil i^uci in unexpected abundance. These beds, where I first saw them extensively intersected, consist of fine-grained compact white sandstone ; interstrati- fied with greenish argillaceous seams, and some laminae of black shale, both containing mica. Upon the upper surfaces of the argillaceous slabs are disposed innumerable groups of Fucoides. Above these layers, other courses, covered with the same fossil plants, could be traced obscurely ; while masses of hard sandstone, whose figured surfaces bore rude resem- blance to the Gothic tracery of ancient sculpture, had evi- dently fallen from much more elevated sites. Pursuing the examination farther eastward, the beds of Fucoides were again laid bare, by the canal excavations, to the height of 50 ft. above the Juniata. Here I counted seven courses of them, comprised within the thickness of 4 ft. Among the lower beds are some of white cherty sub-crystalline sand- stone, and others composed of micaceous schistose sandstone, whose upper surfaces were traversed by another species of Fucoides, distinguished by their long curving stalks ; whilst upon other argillaceous slabs a third description of fossil ioici crossed each other in straight lines, resembling network. It may be remarked, that no casts of shells, nor, indeed, any other organic body, occur with these deposits. At another point, three miles eastward of that where I com- menced tracing the i^ucus beds, numerous seams of fine white sandstone, separated, as before, by thin courses of micaceous shale and clay, are exposed. Some idea of the rapid succes- sion of vegetable deposits will be conveyed, when it is men- tioned that eight or ten were numbered within the space of 6 ft., some of them not exceeding 1 in. thick. The surface of Shade Mountain is too much obscured, by its thick covering of coarse debris, to enable an examination of its structure to be satisfactorily pursued ; but there is reason to conceive that these fossils occur at various elevations, besides those of which I have spoken. I have observed them at 100 ft., 1.50 ft., of North America. S^l and at 500 ft. above the Juniata ; and specimens have even been obtained from the summit. The strata I have enumerated dip towards the north-west generally ; but local derangements have occasioned some par- tial curvatures and arching of the inferior strata, so as to occasion a variation from 30° N.W. to 60° S. The valley of the Juniata is remarkable for the singular contortions, on a large scale, of the strata upon its banks. Lower down the Narrows succeeds a variety of argillaceous beds, which furnish the flagstones for the side pavements of the town of Lewistown. The surfaces of these pavements are covered with irregular protuberances, evidently of vege- table origin, and, probably, another species of fossil ^'Igae, Beyond this point another series of strata occurs. These consist of red sandstones, interlaced with numerous veins of white quartz, and conglomerates of granulated quartz, inter- mixed with fragments of red micaceous slate. Even these rocks occasionally exhibit coarse impressions and casts of Fucbides. To these succeed thick deposits of black shale, having no trace of organic remains. The strata which I have thus briefly enumerated, although they form but an insignificant fraction of this immense series, present matter for the consideration of the speculative na- turalist. It has been seen that here occur many alternating beds of Fucbides, and, probably, several species of these fossil plants. Hence may be inferred the existence, at various epochs, of so many separate surfaces, on which vegetation flourished at the bottom of an ancient ocean. We thus ascer- tain that, in those remote times, there were frequent successions of these remarkable submarine plants, and many renewals of the argillaceous surfaces upon which they took root. But it does not appear that the consequence of these frequent changes was the obliteration or destruction of the organic forms of the vegetation so overwhelmed. The entire series, from the lowest bed even to the highest, appear to retain their original distinctness of outline. In the phenomena of deposition, and of recurring vegeta- tion we may, perhaps, trace some circumstances analogous to the formation of coal beds. The figure which illustrates this article represents a group of Fucbides, on a scale somewhat less than half their actual proportions [the drawing was about an inch too wide for our page]. An assemblage of these groups, ornamenting the sur- faces of large slabs, in clear relief, foinns one of the most i-e- markable fossil productions of this continent. Imagine beds of these Fucbides miles in extent, deposited, or rather accumu- 32 Remarks on the Decay of lated, layer over layer and growth over growth, until the mass contributes to form an entire mountain, and you will have one more subject for contemplation in addition to the innumerable others which result from an enquiry into '* the remains of a former world." R. C. Taylor. LewistowUi Mifflin County, Pennsylvania, Nov. 2. 1833. Art. IX. Remarks and Illustrations on the Decay of the Stems of succulent Plants. By Frederick C. Lukis, Esq. The fossil vegetables which are found in the secondary formation, designated as coeval with the consolidation of the sandstone and coal measures, present to the eye of the ob- server patterns of great beauty and regularity, and display figures which have been often compared wuth the eccentric ornaments of ancient architecture. Without entering into the general geological hypothesis, much may be done, in the study of these interesting remains, by close investigation and analogy ; and, indeed, the nature of fossil vegetables must receive its principal elucidation from the careful examination of existing species analogous to them, when they can be found. The physiological botanist is well aware that plants in decay are disposed to shrivel up, each in a manner peculiar to its own class, and that this operation is governed by their internal as well as external organisation, and by the circum- stances under which they may be placed. As the greater number of our fossil plants have been referred to the ferns, cactuses, and other succulent analogues, it is among these we are to look for characters of resemblance ; and although many of these remains possess dimensions which baffle our conceptions, when brought in comparison with our pygmy tribes of the present economy, still the latter, in- significant as they appear, may aflPord us physiological types sufficiently clear to bring us near the truth. A series of observations made on the drying and decomposition of suc- culent plants has occupied my attention for many years, and I propose to notify some of the changes remarked in the stems and branches of the ASempervivum arb^reum L., or tree houseleek, as it is called, in the course of their decay. They will suffice to show the variety of patterns which may be produced, under favourable circumstances, by a single individual of the succulent class. The result of decay in stems of this plant has been the production of exterior the Stems of Succulent Plants, SS markings, presenting a strong analogy to those of fossil plants ; and I may venture to say that, if casts had been taken from them, they would have been mistaken for real specimens of these interesting remains. The plants, when chosen for examination, were old, and of extremely luxuriant growth. The stems had acquired the size of a man's arm, and were about five feet in height. They were withdrawn from the hot-house during a sharp frost, by which they were soon killed. The leaves dropped off, leaving the rudiment more prominent and perfect than when their removal happened by natural decay. After the death of the plants, they were kept in the mould they occupied, and placed in a shaded situation, where decomposition was allowed to proceed slowly for the space of two years. During dry seasons they were occasionally watered, and the upper part of the stems was scooped out so as to admit moisture in the interior soft parts when required : thus a partial fermentation was con- tinued until the medullary substance became dissolved. The first change observable in the appearance of the epi- dermis was a disposition to form regular ridges or risings in the interstices between the marks left by the leaves and sub- spinous nerve near them, preserving a reticulated pattern. The hardness of the ligneous centre resisted decay for a long time, and allowed the cortical covering to form its pattern with considerable exactness ; and at last, by its own shrink- ing, and the want of farther resistance from the nerve of spine and leaf, the covering contracted in a longitudinal direction, leaving the end of the wood projecting beyond the upper part of the plant. The following drawings of the plants, taken at different stages of decay, will be better understood than a lengthened description. Fig, 7. represents the common appearance of the stem, deprived of its leaves, before decay ; the tubercle and rudi- ment of the leaf, in quincuncial order, scarcely rising above the epidermis. Fig, 8. This figure shows the first angular depression round the tubercle and leaf, caused by the shrinking of the interior parts of the plant : the dried state of the cortex opposing the contraction of its circumference. Fig, 9. is part of the same stem, contracting more equally downwards, it having been more under the influence of moisture than the lower end. It had now commenced a wavy and rhomboidal cancellated figure, the elevated ridges preserving an almost united wavy line from top to bottom. Fig. 10. The same as the last figure, having now attained Vol. VII. — No. 37. d 34 Remarks on the Decay of 8 a more decided pattern, by the completing of the above-stated rhomboidal depressions, which had been assisted by a longi- tudinal cut of a knife, and the careful removal of the woody centre. 10 11 ■ 12 13 Fig, 11. Other parts of the plant produced this pattern. It appeared that the spinous processes in the interior had resisted the vertical contraction of the cortex. Here the spaces retained an oblong form, having the elevated ridges prominent, though not united throughout their diagonal direction, but breaking into distinct approximate compart- ments, much in the same manner as those in the Phytolithus cancellatus. (Jig, 21.) Fig, 1 2. The most general appearance of the plants, where contraction was carried on more equally from both ends of the branch. The elevated ridges surrounding the compart- ments had now become dry and hard, and might be said to have arrived at the state of hay. Fig, 13. is a vertical section of a branch, to show the lig- neous centre, or woody stem, in a fresh state. Fig, 14. The same after decay had commenced. The woody centre, in contracting, had produced lengthened lozenge- shaped elevations, retaining the spinous processes rather pro- minent. the Stems of Succulent PlaJits. 35 15 16 17 Fig. 15. A longitudinal section of a branch, to show the disposition of the medulla, or pith, in the ligneous centre, where it forms transverse cells : the cortical cells or layers, running in a vertical manner, are traversed by the spinous nerve which produced the elevations in the epidermis. Fig. 16. represents the base of the stems of old plants. The epidermis becomes hard and leather-like, and is generally ruptured by the enlargement of the subspinous elevations. In the case under consideration, it formed lozenge- shaped open- ings round each tubercle, and retained a slight remain of the impression left by the original leaf across the tubercle. Fig. 1 7. In this last figure decomposition had affected the interior so as to enable the cortical covering to sink between the stiff prominent spines, which resisted decay with greater obstinacy; thus forming rhombic compartments in a reversed order to wliat had taken place in the younger branches, as seen in^^, 1 1 . A greater variety of figures might have been produced, but as many were the same in character, under a few modi- fications, and in progress of decay, I have chosen the most decided patterns only. Some interior changes in the epi- dermis, cutis, and ligneous centre presented very regular markings during the progress of decomposition and desic- cation. Fig. 1 8., taken from the inside surface of the epidermis of the largest stem, will suffice to show the various changes exhibited by a single plant : in this case the cortical parts, under the epidermis, had separated in macerating, and left it at liberty to produce this pattern, although the exterior surface was not much altered from the rest of the plant. In this figure the hollows were numerous and deeply marked. Over each a transverse, sharp, wavy, elevated line passed in regular succession; undoubtedly formed after its separation from the rest of the plant. These lines were not marked on D 2 36 Remarks on the Decay of the outside of the epidermis, nor were they at all visible on the remains of the soft part which had been in contact with it. Fig, 19. is a portion of the stem, or lignum^ from which, when perfectly dry, its bark has been removed by peeling. It formed a hard and tough cylinder, of moderate thickness, the longitudinal striae being only interrupted by the slightly elevated spots which held the spinous nerves as they emerged from the wood, and then passed through the bark, where they formed the external rugae. That part of the bark which immediately covered the wood retained the same impressions on its surface, but that in contact with the epidermis had large tubercles corresponding with the outside of the plant; but in no case did this portion of the bark exhibit a pattern dissimilar from it. In fossil plants it has been remarked that the same species may appear under three different states; such as are produced by the epidermal, cortical, and ligneous configurations : the first and the last differing much from each other ; and, as Mr. Parkinson states, " it is only close observation that deter- mines that it originates from the same plant." Assuming that fossil succulent plants have undergone changes similar to those here represented, either before they were lodged in their matrix, or when so embedded, it will be easily perceived that one species may appear under several aspects difficult to determine. It is not improbable that, during the progress of maceration in the matrix, a variety of circumstances may have occurred to favour these changes and variations. In contrasting these observations with what is visible in the submarine peat found in these islands, many indications point out a similar decomposition to be going on; and although these trees and vegetables have been buried many centuries, and are of a different description from those under notice, yet they exhibit changes nearly as difficult to recognise. the Stems of Succulent Plants. 37 On referring ir^^^^^"C-l ^^ Parkinson's Outlines of O- ryctology (the only work near at hand on the subject), he there states, when treating of the Phyt6- lithus verru- c5sus(^^.20.)) that this fossil was a plant of the succulent tribe, differing from vegetables of the present world by its containing a more solid part within its succulent substance, from which proceeded a delicate organisation, by which a communication was pre- served with the external surface." He further adds : — "It also appears that the species of this genus, distinguished by their characteristic markings, may have been numerous ; that the different situations in which the internal part is found in different fossils are attributable to the resolution of the ten- derly organised intermediate part, connecting the included substance with the surface, and to the other accidents depend- ent on partial and irregular decomposition, pressure, and distortion, occurring during its passage from the vegetable to the mineral kingdom." M. Steinhauer has also remarked, in speaking of the Phytolithus cancellatus {Jig, 21.), " that the first or epidermal Epidermal, Cortical. ^ Ligneous. configuration is formed of rhombs, divided by lines forming a network in a manner difficult to express by drawings or D 3 38 Geological Discoveries at Billesdon Coploxo), description, which leaves the rhombs still app'oximate ;" he again adds: — " In the h'gneous, the cancellated appearance is here entirely losty the surface is slightly striated, with a scarcely perceptible rising under the central ridge, and a minute but distinct raised dot in the place of the depression in the epider- mis. It has all the appearance of a peeled plant, which had been furnished with small branches or spines in quincuncial order." M. Steinhauer also remarks, " that these plants were furnished in the centre with a pith of a structure differ- ing from the surrounding wood or cellular substance, more dense and distinct at the older end of the plant." Comparing these statements with the appearance of the plants under review, a strong analogy will be observed be- tween them, tending in some degree to elucidate this obscure subject, and bringing their variety of configurations nearer to our minds. It may be found interesting to those who have not examined the different states of the same plant while under decay, and may prevent the multiplying the number of species, whose only difference, perhaps, exists in the degrees of decomposition of the same plant.

A Notice of some important Geological Discoveries at Billesdon Coploiv, Leicestershire; tvith Observations on the Na- ture of their Relation to the modern System of Geology. By Joseph Holdsworth, Esq. In contemplating the numerous theories of the earth's struc- ture and materials, which have from time to time been advanced by men of profound minds, one cannot but be struck with the discrepancy of those ideas and opinions which, like the ebul- litions of fancy, have successively triumphed and radiated with an effulgent brightness, until the discovery of some new, some simple unexpected fact, some sad reality, has consigned them, in succession, to oblivion. Much, very much, however, has undoubtedly been achieved ; many luminous discoveries have been made, and many sur- prising truths have been established, by the meritorious exer- tions of the scientific, as is sufficiently exemplified in the modern system of geology. This system, however, notwith- standing it is countenanced by many of the most scientific characters of the age, may be far from the climax of perfection ; and the warmest advocates of it even admit that it is liable to many weighty objections. Indeed, the complex, the multi- farious, the extraordinary diversity everywhere observable in and their Relation to the modern System of Geology, 39 the terraqueous arcana of nature, laugh at the poverty of our ideas, and mock the futile efforts of man to reduce them to system, or to effect anything approaching to a faithful delinea- tion of so mighty, so mystical and magnificent a prototype. Notwithstanding this, there are certain individuals vs^ho, in their anxiety to preserve inviolate adopted principles and pre- conceived notions, treat with disdain or levity such actual cir- cumstances as do not happen to accord with their prepos- sessions, and thereby evince a disposition to give, rather than to receive, the laws of nature. Certain geological discoveries which I have recently made in this district, and of which a short account is published in Taylor's London and Edin- burgh Philosophical Magazine and Journal of Science, vol. iii. p. 76. 112., 1833), have met with instances of this kind of re- ception ; and on this account, as well as by the advice of some eminent literati who liave examined the discoveries, I am in- duced to solicit the farther attention of the unprejudiced scientific to them and to their bearing on the existing system of geology. This system originated in the labours of Mr. Wm. Smith, an English surveyor, who in 1790 published his Tabular Views of the British Strata ; in which he proposed a classi- fication of the secondary formations in the west of England, and contended that the order of different groups is never in- verted, and that these groups may be identified at very dis- tant points, by the presence within them of fossils of a deter- minate structure, peculiar to each. According to the order of superposition and marks of identification prescribed by Mr. Smith (admitting the infallibility of the latter in the present case), it appears, from the occurrence of the Gryphae^a in- ciirva and Pentacrinites Briareus in the site of ray trial for coal, that it is in the stratum which science denominates lias, and is situated about five miles from the eastern edge or ex- tremity of the red marl. The last-named stratum, according to Mr. Smith's doctrine, reposes upon coal measures, and dips under the lias clays ; consequently, if Mr. Smith's doctrine be true, and we assume the undisturbed presence of the above beds in this district, the lias and red marl formations must be penetrated before the old coal formation can be reached. The mean thickness of each of the two former strata is, according to the calculation of some geologists, about 500 ft. ; the thick- ness varying extremely in different districts, even down to six or ten feet, and, in some cases, one or both of the beds are entirely wanting. At the Glutton Ridge pits, the red marl is, in some places, thirty fathoms deep, and in others but ten. I will not stop here to question the correctness of the theory D 4 40 Geological Discoveries at Billesdon Coplow, which ascribes to every distinct stratum a new order of organic beings, nor dwell upon the unanticipated facts which my prac- tical efforts have brought to light in this locality ; but, in actual consistency with Mr. Smith's theory, I will proceed to adduce a few of the many instances which have occurred in this kingdom of the successful penetration, even from the surface of the oolite, to the carboniferous strata or independent coal formation. As instances : Paulton Hill, near High Littleton, Gloucestershire, is topped with oolite, beneath which is a bed of lias ; then the newer red sandstone or marl, and finally the pennant or coal seams, at a moderate depth. In another part of the same county, the thickness of these beds, which lie above the coal, is as follows : — Oolite, 6 yards ; lias 53 yards ; red marl, 44 yards : in all, 1 03 yards to the coal form- ation. Coal is equally accessible through these formations near the Mendip Hills, and in some parts of Wales, &c. In the above districts, as in all others, the various superstrata of the carboniferous formation vary much in thickness, in compara- tively short distances. The Walton pit, a short distance east of Glutton, and near to Midsummer Norton, descends through the red ground, containing shaly limestone, in which fossils abound, and through the like order of mill grit, shale, and sandstone, to the depth of 200 fathoms, where the main bed of coal occurs. These instances sufficiently demonstrate the probability of the existence of coal in this place, at an obtain- able or definite depth, especially when we take into account its proximity to the red marl and newly discovered coalfields to the west, and distant hence about fifteen miles in a direct line ; and, additional to these considerations, we may reason- ably calculate upon the latent existence, and consequent assistance, of some of those wise ordinations of Providence termed faults, by means of which the coal of very extensive fields is found to be, in many instances, thrown near the sur- face, when otherwise it would, in consequence of its natural dip, soon be out of the reach of the miner. In the vicinity of these natural intersections (the consequences of subterranean convulsions), vast stratified masses, several miles square, are found to have been upheaved from very consider- able depths. From among hundreds of instances of this case on record, I may here adduce two or three in illustration : — The coal formation of Ashby Wolds is a curiously denudated mass, entirely surrounded by the red marl, which (if it existed prior to the catastrophe) appears to have fled from its assigned geo- logical destination, when the volcanic thunders shook the mi- neral treasures of its sub-neighbours, and summoned them to approach nearer to the light of heaven. The coal measures of and their Relation to the modern System Of Geology, 41 Tamworth, and some others in the red marl, assume precisely the same insulated character ; but the systematist affirms that these anomalous masses are peculiar to the red marl. Since, however, he attributes them to igneous causes, whose bounds no lines of demarcation can prescribe, whose power and universality no mortal dare presume to dispute, may we not reasonably infer that immense stratified masses have been subjected to the same mighty causes, not only throughout the whole of this kingdom, but in the remotest regions of the globe? So recently as the 9 th of November, 1822, an earth- quake happened in Chile, South America, which furnishes an amazing example of the extensive effects of the tremendous explosive powers by whose agency such awful catastrophes are operated. Mrs. Graham, who was an eye-witness of the above, relates that, " on the morning of the 20th, it appeared that the whole coast, from north to south, to the distance of above one hundred miles, had been raised above its former level ; at Valparaiso, the alteration of level was about three feet, and at Quintero about four feet. She found good reason to believe that the coast had been raised by earthquakes, at former periods, in a similar manner ; several ancient lines of beach, consisting of shingle mixed with shell, extending, in a parallel direction to the shore, to the height of fifty feet above the sea." These phenomena may be regarded as of frequent occurrence in the formations of all ages, and as indicating the most effective of the numerous disturbing causes by which the earth's surface has been affected. I am prepared to show the igneous effects of these revolu- tionising catastrophes in the vicinity of Billesdon Coplow. At an apparent fault, which intersects the southern extremity of the Coplow basin, where many of its deep measures are pro- miscuously thrown up, are found large masses of fused mat- ter, muscle shells, coal, and oyster shells, in conglomerated masses ; fragments of fir trees, partly carbonised and striated with sulphur; all evidently having been subjected to the powerful action of fusible heat. From what I have adduced respecting the universality of lands uplifted by subterranean convulsions, and from the signs of these convulsions having at some remote period exercised their powerful and mystical effects in this district also, is it not reasonable to infer that im- mense anomalous masses are as likely to expand their denu- dated bosoms in the centre of the lias marls, oolitic, or other ranges, as they are well known to do within the limits of the red marl ? However, there can be no necessity for resorting to such violent hypothesis, as the instances we have quoted are sufficiently in point to warrant fully (with a full and un- 42 , Geological Discoveries at Billesdon Coplaw, compromised admission of the undisturbed order of super- position of the British series of strata) the conclusion that coal may be reached and worked to advantage from the sur- face of the lias, and even oolitic, ranges of this kingdom. But however powerfully and clearly the inferences drawn from the general laws of an established science may tend to justify such a decision, the prudential calculator and nice observer of nature's laws would certainly not feel himself justified in the adoption of expensive practical experiments to prove the real existence of an object which natural deductions, derived from theoretical principles, had shown to be probable. " No;" he would naturally enough say, " I must first be convinced, by indubitable evidence, of the real merits and stability of this grand and orderly structure which the inductive spirit of modern geology has called into being; and even then, before I proceed to act upon principles of so general and comprehen- sive a character, I shall require a mass of actual evidence (of a local nature) perfectly analogous to those infallible criteria which are known to direct and reward the researches of the practical geologist and mineral explorer." Such, I confess, were the sentiments which dictated my examination for coal strata in this hitherto untried district. I will now proceed to consider whether or not the disco- veries already made are calculated to affect or confuse the order of superposition of the British series of strata, so sys- tematically arranged by modern science, and also endeavour to demonstrate the presence of valuable coal strata in this dis- trict, by existing evidence, of such an incontrovertible nature as, I flatter myself, cannot fail to remove the prejudices of the most determined sceptic. The marks of identity by which the respective formations are distinguished, and their geographical extent ascertained, are, as I have before observed, the fossil exuviae they indi- vidually contain. Such being the case, I would ask the founders of the existing system to account, by reasonable in- ferences, for the assemblage here of the Cirrus acutus of the mountain limestone ; the Pecten fibrosus of the under oolite ; the Trigonia costata of the upper ; the Mytilbides labiatus, from the chalk and superior strata ; with madrepores, muscles, corals, and oysters from the coal formation, found, apparently, not in the diluvium or adventitious deposits, but in the regular strata, constituting a part and portion of the ponderous form- ation denominated lias ? In relation to this question, I shall here introduce an extract from the Rev. Mr. Scutcliffe's Geology of the Avon (p. 24.): — " With regard to organic remains, the marble, often alternating and their- Relation to the modern System of Geology. 43 to magnesian limestone, the shaly limestone, and the oolite, contain the genera, the families, and species of shellfish, ma- drepores, coralites, encrinites, pentacrinites, far beyond what scientific men have attempted to distinguish. Mr. John Walcott has very accurately painted and engraved about sixty shells, besides leeches, bones, and palates ; Mr. Sowerby, in his beautifully coloured work on shells, has published many others : but these do not contain the fourth part of the spe- cies which exist in gentlemen's cabinets. This science, which merits the most enlightened classifications and the best powers of the pencil, is yet in a state of infancy. But of seeing it brought to perfection one can have little hope ; learned men having unaccountably committed themselves, by contending that in every fresh order of strata we meet with an entire fresh order of extraneous fossils. It is granted, at once, that we do meet with such order; for the works of the Creator are im- mense. We meet, also, with fresh plants in every continent. Nevertheless, in all these fresh orders of strata, we meet with many shells and plants found nearly in all the other orders. These are facts founded on personal examination and the severest scrutinies. These are facts which command the judg- ment, and must eventually supersede the contumacy and novelty of our modern theories. No man will surely tell us that the belemnites, the ammonites, the ostracites, the trochites, the nautilites, and the gryphites, found in the lowest strata of the alum shale of Yorkshire are of a totally different order from those of the same name in this district, and in the chalk and limestone ranges of the south of England. I have seen three of the Yorkshire ammonites, which differ from those of the south ; one of which had mouldings on the whole spiral coil, resembling the edges of the oak leaf." Of vegetable fossils, embedded in the same mass, many occur ; some of a species of fir, and of other dicotyledonous woods; also detached leaflets of the osmund filicite upon nodules of ironstone, and other vegetable impressions upon the sandstones (found on the spot where the coal and its con- comitants crop out to the surface) ; which fossils are described by geologists as belonging to the old coal formation. To these I may add the extraordinary circumstance of the pre- sence of an immense number and great variety of tropical fruits, with knots of wood, and other vegetable fossils, found in a most perfect state, embedded in the regular stratifications, about fifteen feet from the surface of the earth, and on the spot where the boring for coal was performed. These fossils have been pronounced fruits of a tropical climate by many eminent scientific men in London and Edinburgh, where they 44 Geological Discoveries at Billesdon Coplow, have been shown, and are universally allowed by the initiated to be the first discovered within the lias range. The records of geology furnish us with a description of a similar discovery of the organs of fructification belonging to a tropical climate being made in that division of the British strata (superior to the chalk) termed the London clay, which is, according to the present system, a deposit of a much more recent epoch than the lias. In reference to these fossils, which were found in the Isle of Sheppey, the following remarks are extracted from Conybeare's Geology of England : — " The evidence of a neigh- bouring region of dry land seems attested by these vegetable remains, which, from the state in which they are found, can scarcely be supposed to have been drifted from any great dis- tance. . . We can scarcely resist the temptation of asking, What was that ancient land ? Had any part of England then raised its head above the waves ? Does it not sound extravagantly, even to enquire whether its oldest and highest mountain tracts then formed a group of spice islands , fre- quented by the turtle and the crocodile? Speculations like these, though unavoidably suggested, almost give the features of romance to the sober walks of science." According to the author above quoted, beginning with the coal formation as the plane of superposition, the Has is the second, and the London clay the fifteenth in the geological series of English strata ; consequently, according to the doc- trine of the relative ages of strata, a series of epochs transpired, or geological catastrophes performed their respective revo- lutionising effects on the face of this country, during the im- mense period which intervened between the formation of the lias and London clays. Now, bearing in mind the data (fos- sils) from which these inferences are drawn, the following queries naturally suggest themselves : — How are we to account for the presence, in strata deposited subsecutively to the car- boniferous strata, of some of the identical fossils (of tropical origin) which characterise the carboniferous formation ? From whence came, and at what particular epoch flourished, the tropical organs of fructification, &c., found in the lias ? What are we to infer from the circumstance of analogous vegetable products of the same climate being found embedded in strata supposed to be formed at periods so remote as is ascribed to the deposition of the submedial and superior formations ? Whilst indulging in such speculations as the above, we have, for argument's sake, admitted the modern doctrine of a series of subaqueous catastrophes and progressive changes having, in the course of an immeasurable space of time, coated the globe with regular and well-defined strata, whose order of and their Relation to the modem Si/stem of Geology, 45 superposition is never inverted, and, being countless in number, her incalculable age is, of course, understood. But the mind, in its eager pursuit after secondary causes (for- getting the First Great Cause), is speedily lost and confounded in a labyrinth of soaring conjectures and humiliating reflections; and truly, then, " may the sober walks of science be said to assume the features of romance." But, if we refer to the sublime and consistent records of 'the inspired writer for assistance, the daring phantasm of system vanishes into thin air, under the profound declarations of the sacred page. Moses, in speaking of the grand catastrophe whose impetuous waters overwhelmed the primitive world and its inhabitants (of which event we have such abundant evidence), declares that " the windows of heaven were opened, and the fountains of the great deep were broken up," and that " the high hills under the whole heavens were covered ; " and he further affirms that the great turmoil of waters " prevailed," or, in other words, continued their impetuous course, for a space of 270 days around the nucleus of the revolving globe. Surely such a mighty circumfluent mass would be quite sufficient to produce, during the above period (under the energy and guidance of Him whose " spirit moved upon the face of the waters ; " who said, '* Let there be light, and there was light ; " whose creative fiat willed all things into being), the whole of the terrestrial formations, with the peculiarities ascribed to each ; all the astounding phenomena which the philosopher labours in vain to define ; all the magnificent framework of the world, so greatly to be admired for the beauty and diver- sity of its materials, and for the provident and orderly arrange- ment of its structure. The Rev. Mr. Scutcliffe observes (in his valuable geological essays), that " the Mosaic theory of stratifying the earth, by the long-continued action of tre- mendous tides, is the only one which can correct the contra- dictory theories of geologists, and illustrate the phenomena of the stratified earth." He also remarks, " that whatever earths the impetuous tides of the deluge washed from one place, they must, of necessity, deposit in another. This is an inva- riable law of the ocean. Hence, one tide would bring gravel and marine exuviae, already worn by the action of the billows rolling on the shore ; another would bring sand, and another clay. But though all alluvial strata were formed of the de- tritus of the old earths, they would repeat the first formation, by combination ; they would change into a variety of silica, rocks, marls, and minerals ; while ©thers, falling on more neutral earths, would remain in their primitive state. Thus, also, the deeper strata of the earth would be laid on while the 46 Geological Discoveries at Billesdofi Coplow, waters were rising; and all the more loamy earths by the gradual retreat and subsiding of the waters. These long- continued actions and deposits of the water are a sure guide in accounting for all the conformations and heterogeneous masses found in most parts of the alluvial earth." Thus, with the semblance of truth on our side, and reason for our guide, we may unhesitatingly infer that the tropical fruits, plants, and other fossils, which we find so indiscrimi- nately scattered in the submedial, medial, and superior strata of geologists (and many others, which may also arise from their fossil tombs, at some distant day, to prove the fallibility of modern theories), were upborne to their respective destinations by the levelling floods of the Noachian deluge ; and, conse- quently, are, like the strata in which they are embedded, of contemporaneous origin ; and were, in all probability, deposited at a period when no portion of England had raised its head above the waves. May we not also fairly surmise that the sportive element, which had arbitrarily disposed of the fossil exuviae, would also, by a succession of retiring tides, leave, in- discriminately, its vast flotillas of the uprooted spoils and refuse of the antediluvian forests in the deeper recesses of the earth, in the insulated situations they now occupyjn the charac- ter of coals ; and of the immediate existence of which we have certain infallible indications, ordained by the all-wise Director and Disposer of all created things for the direction and assist- ance of the " practical explorer ; " who, by the evidence of these indications has been led to the discovery of those im- mense treasures which have proved the mainspring of the activity, prosperity, and glory of the British nation. I will now proceed to show that " local indications" are to be found in this district, presenting their silent but incon- trovertible testimonies of the immediate presence of mineral riches, concealed here, in the subjacent regions of the earth. Passing over the numerous veins, detached masses of smuts and coal (as being indicative, only upon more general prin- ciples, of a coal neighbourhood) so numerously scattered throughout the diluvium or compound beds which principally constitute the multifarious undulations of this (the eastern) division of Leicestershire ; the first thing worthy of notice is the circumstance of the vestigia of coal, and all its concomi- tants^ being found, generally speaking, immediately below the surface of the ground, in one continuous line, traversing this field in a direction due N.E. and S. W. ; five miles of which have been minutely explored by myself, and its real character and importance ascertained and declared by several expe- rienced scientific and practical men. From the outcrop, these and their Relatw?i to the modern System of Geology, 4:7 measures decline rapidly to the S.E. ; but in traversing the lower grounds, where the greater portion of them have been actually proved, by boring, to lie in regular stratified order, they dip but about five inches in the yard to the above point of the compass. In regard to the quantity of coal, I may adduce the single fact of the vestigia of certain of its conco- mitants, of considerable thickness (say from three to eighteen feet), proved in the deep, being found throughout the whole of the longitudinal line of the bassets, bearing a propor- tion short of the coal vestigia there scattered. Reasoning from this fact*, in conjunction with coexisting evidence, it is demonstrable to a certainty that the latter are portions of a very considerable and valuable stratum of coal, occupying its individual station, as a part of the mass of stratification partially explored, and whose bassets, or vestigia, were evi- dently deposited at the same period and by similar means. As a concurrent proof that these vestigia have been carried but an extremely short distance from their respective beds, I need only remind the initiated (who are aware of the ex- traordinary chafing or decomposing power which impetuous waters exert upon some of even the hardest minerals brought from any distance) that the various freestones, shales, coal, &c., found at the crop, are not in the slightest degree worn by attrition : even of the binds, which are of an extremely friable, tender, and sol uble nature, I have numerous specimens, whose angles and asperities are of the most acute description. About 400 yards beyond the first basset another coal appears to the day ; which, in some places, has been discovered two feet thick, and also accompanied by its immediate con- * An exactly analogous line of coal vestigia, and all its concomitants, varying from about 10 yds. to 30 yds. wide, traverses the new Leicester- shire coalfield, in a direction due N.E. and S. W. ; which vestigia are thrown up to the surface through the red marl formation; a very con- siderable thickness of which entirely conceals the superficies of the sub- strata (carboniferous) over a great extent of country. The important cha- racters of these bassets were first noticed, examined, and appreciated by Mr. Williamson (an experienced practical coal discoverer and miner), who, placing that implicit confidence in them which experience in exactly similar evidence (or laws of nature) had taught him to entertain, was thereby encouraged to persevere in a long and tedious trial (by boring) for coal in Bagworth Lordship (made a few hundred yards to the west of the above line), which, after penetrating through about 103 yards of red marl, ulti- mately led to the discovery of the vast stores of coals now working there • and other collieries subsequently opened in the immediate vicinity. Ac- companied by Mr. Williamson, the discoverer of the above coalfield, I have recently traced and very minutely examined the, aforenamed carboniferous bassets, and found them, in everi/ peculiar and essential character , precisely analogous to those which traverse this district. 48 Geological Discoveries at Billesdon Copious comitants, and resting upon a clunch, the usual pavement of coal : this has also an almost vertical dip to the S.S.E. Here, as in the first bassets, confusion and disorder are apparent; but this, as Williams asserts, in his History of the Mineral Kingdom^ is common to all strata which, as in this instance, come in contact with the base of hills or other previously formed elevations. In reference to the measures proved by boring, it may be necessary to state, that men of unquestionable judgment have not only recognised them as the identical strata represented by their vestigia at the surface or line of bassets, but pro- nounced them to possess, collectively, precisely the same mineralogical characters, &c., which so definitely distinguish the old coal formation. It may be important to remark, that, in the course of our penetrating the upper beds of this form- ation, marine exuviae were found tolerably abundant, but de- creased until we arrived at, apparently, the old coal formation, where they entirely disappeared, and were succeeded by those of vegetables alone. The carbon, which gradually increased in the measures, was, in the last * fifteen or twenty yards, ex- tremely abundant ; indeed, quite equal in quantity (as proved by the common process of washing) to any of the strata in the immediate vicinity of the coal beds of the explored coal- fields. This lower series also contained two or three thin veins of coal, commonly called breeders. Can any thing be more clearly demonstrative of the total absence of the red marl (in this vicinity) from its assigned geological position ? However, there appears nothing extraordinary in this circum- stance, when we take into consideration the extremely variable thickness of all the secondary formations, and particularly the red marl, or new red sandstone, which, it is well known, is frequently found terminating abruptly, forming thin beds, or swelling into considerable thickness, in the comparatively short space of a square mile or two. To revert to the fact of the bassets of the coal and all its concomitants, accompanied by the characteristic fossils of the old coal formation, traversing this district in a direct line: whether they result from igneous or aqueous causes ; whether they are calculated to break or disarrange the concatena- tions of the modern system, or whether they can be recon- ciled thereto, I leave to the learned to determine.

In the contemplation of unanticipated or unpalatable truths, the determined sceptic and uncompromising systematist should ever bear in mind that there are many phenomena in the mag- nificent arcana of nature which the accumulated wisdom of ages, even to the end of time, shall fail to demonstrate ; that " the book of nature," as Bishop Pontoppidan observes, " con- tains many leaves which no mortal ever yet perused ;" and, consequently, it behoves the votaries of system, who aim at perfection, so to construct their scientific temples that the admission of any of the unexplored truths contained in her sacred pages may not sap their foundation, nor disturb the general harmony of the structure. That this would be a hard task is admitted ; but, in contemplating the extreme jea- lousy and pertinacity sometimes evinced by the privileged few who are permitted to assume the banner of science, one can scarcely resist the inclination to indulge in such reflections. In a complex subject like geology, the abstruse disquisitions of the theoretic must ever remain subservient to the actual discoveries of the practical. However at variance such dis- coveries may happen to be with the previously adopted notions, prevailing opinions, or vested interests of individuals or socie- ties, they will ultimately, despite of every disparagement, jpre- vail, and find their way into the stores of public knowledge ; where unshackled liberal and inquisitive minds will appreciate them according to their worth, and where, perchance, they may occasionally merit to be received as new data, whereon to found speculations and enquiries which may ultimately tend to the farther developement of science and the extension of national wealth.

XL Some Observations on a very interesting Aurora Boreah's, witnessed at Hull on the Evening and Night oj^ October 12. 183S- By George H. Fielding, Esq. M.R.C.S.L., Member of the British Association for the Advancement of Science, Treasurer and Hon. Curator of Comparative Anatomy to the Hull Literary and Philosophical Society, &c. &c. On the evening of Saturday, Oct. 12. 1833, we had the most brilliant exhibition of the aurora borealis I have ever seen. The evening was remarkably bright and clear; the sky presented a deep blue tint, and the stars were uncom- monly brilliant; the air felt sharp, the temperature being about 40°; the pressure of the atmosphere 29*832; the wind rather brisk, and from the north-west. At half past 8 p.m. there was a broad, irregular, semicircular belt of vivid white light, stretching across the northern hemisphere of the heavens. The span of the arch was from 70° to 80°, its upper edge reaching as far as the star Eta in Ursa Major, about 18° above the horizon ; and the breadth of the belt, which varied, I should state to be about 5°. It was exactly similar to a rainbow in shape, but of pure white light. Below the bow 1 at first thought there was a dark black cloud ; but, on minuter investigation, I found this to be a deception, caused by the extreme brilliancy of the aurora, which threw the surrounding medium into shade, and ob- scured the lustre of the fixed stars so much as to make them seem blue. By degrees the arch extended itself towards the zenith, and included the whole constellation of Ursa Major : it also gradually filled up the concavity down to the horizon, until it finally presented the magnificent appearance of an arc of an immense globe of fire. During the whole time of my observation, brilliant radii were shooting up towards the zenith from the convexity of the arch, sometimes broad, sometimes narrow, sometimes vanish- ing immediately, and at others remaining visible for a minute or more, to an altitude of 60° or 70°, and seeming like pillars of flame. The radii mostly disappeared at or before they had attained, an altitude of 90°, but might occasionally be traced in very narrow wavy streaks into the southern hemisphere. The most extraordinary appearance, however, was a rapid undulatory motion, accompanied with frequent brisk flashes *, * These flashes resembled, both in duration and colour, the silent light- ning frequently seen in the horizon on warm summer evenings, apparently at an immense distance, and when not a cloud is visible. I cannot but consider the aurora as an electrical phenomenon, and think that, were it not at such a remote distance, we should have explosions audible as in a thunder storm. This, however, is mere conjecture; but I recently witnessed at Hull. 51 which extended through the whole length of the curve. These immense flashes reached an altitude of 80° or 90°, and were often divided into numbers of square portions, or flashes, separated by broad dark lines. This singular phenomenon I should judge to be owing to the intervention of patches of dense vapour between me and the aurora; and, as not a cloud was visible during the interval between the flashes, and as the stars preserved their brilliancy, the height of the aurora must have been immense. As a diagram, however rough, excels description in these matters, I add a slight sketch (j%. 22.) of the appearance when the square masses were given off. I think the exhibition was the most splendid about 10 p.m., although it continued very beautiful till after 2 a. m. There was not the slightest corresponding appearance in the south, nor could I distinguish any sound I could attribute to the aurora : in fact, the latter is perhaps hardly to be expected, as the mean distance of the aurora from the earth, as cal- culated from the observations of twenty different philosophers in the same century, is, according to Sir Richard Phillips, 500 miles; the distance observed varying from 100 to 1000 miles. With respect to the very remarkable changes in the weather, and especially in the temperature, which immediately fol- lowed this certainly uncommon exhibition of the aurora in these latitudes, and which I am about to detail, a large share, in the absence of any other known cause, may fairly be attri- buted to this phenomenon. During the night the temperature fell to 34?°, being the lowest degree of cold I have registered hope soon to see the matter fully explained, as Captain Ross (whom I had the pleasure of seeing immediately on his arrival at Hull, after his long absence and perilous adventures) himself informed me he jiad obtained ample and satisfactory information respecting it and its causes. E 2 52 Short Commitnications : — this season : the barometer rose slightly. On the following morning, at nine o'clock, the northern hemisphere of the sky was studded with the mottled cirrostratus ; the wind was brisk from the west, but tending to the south ; the pressure of the air 30*096; the temperature 41*9°, being 7"2° lo*isoer than the preceding morning at the same hour. The temperature remained low the whole day, the sky wild, and the wind increasing until the evening, when it blew strong from the south-west in gusts, and was accompanied with showers of rain, the temperature increasing considerably. At nine a. m. the following morning the thermometer stood at 58*8°, being 16*9° higher than the preceding morning: the barometer showed 29*417, being a fall of '679, or rather more than half an inch. The early part of the day was bright, with a fresh breeze from the south-west : at two p. M. it became overcast, and a heavy shower of rain fell : at night it blew strong from the south-west, accompanied with showers of rain, and once of hail. On the 15th, at nine a.m., the temperature was 46*1°, a decrease of 12*7° from the preceding morning: the baro- meter 29*132, and ultimately sinking to 29*118. These great and sudden differences in temperature are very uncom- mon at this time of the year, and actually greater than many of the same parallel hours in June and January of the present year, as I have found by referring to my own observations. Hull, Oct. 18. 1833. Art. XII. Short Communications, Birds. — A Notice of some rare Species of Birds observed or Jcilled in the County of Suffolk, and adjoining Borders of Essex, during the Winter Months of 1 8S2 and 1833. [% J. D, Hoy, Esq., of Stoke Nayland^ Suffolk.'] Two Eagles of the cinereous or white-tailed Species (Falco Mhicilla), but in the plumage of the sea eagle (F. Ossifragus), were, in December, 1832, trapped on a large rabbit-warren, near Thetford [and, it may be assumed, from Mr. Hoy's heading, on the Suffolk side of this town, which itself is just within the boundary of the county of Norfolk]. They had been observed for some time in the neighbourhood. One of the eagles carried a heavy trap a considerable distance, I believe, nearly half a mile, and was secured with some diffi- culty. One was apparently in its first year's plumage : the other, from its lighter-coloured feathers, and the tail-feathers possessing much more white, was probably a year older. They were both presented to me by G. Gardiner, Esq., of Thetford. Birds, 53 They are the very birds to which the remarks and query (VI. 448.) of H. T. of Bury St. Edmunds relate. A Goshawk {A!stur ^alumbdrms), an adult male bird, in most beautiful plumage, was, on March 16. 1833, caught by a gamekeeper of Sir Joshua Rowley, Bart., of Stoke Nay land, in a trap baited with a red-legged partridge, which it had killed. I believe its capture to be an exceedingly rare occur- rence in this part of the kingdom. I am not aware of more than two or three instances of the goshawk's being killed in the southern parts of Britain ; and, in those instances, I am inclined to suspect they might be birds escaped from falconers, as the goshawk has been trained and flown, at no very distant date, in the counties of Norfolk, Cambridge, and Herts, in which counties also the specimens were killed. T/ie Merlin {Fdlco lE/salon) seen. The Peregrine Falcon {Fdlco peregrlnus) seen. The Hawfinch (Fringilla Coccolhraustes) [VI. 520., and, in addition to the references there given, III. 436.] visited us in small flocks, and many were seen and shot in different parts of the county. Although the whitethorn berries were abundant, the seeds of the sycamore and maple appeared to be their favourite food, more particularly those of the sycamore. A flock of eight or ten frequented some plantations near Ipswich during a great part of the winter, and seemed to feed almost entirely on the sycamore seeds. They were shy, and difficult of approach. Siskins {Fringilla Splnus) were very abundant through the winter, feeding principally on the seeds of the alder. S?ww Buntings {E?nbe?iza nivalis) in large flocks, in marshes and fields contiguous to the coast. The Great Butcher Bird {Lanius excubitor) seen in Tendring Hall Park, Sir J. Rowley, Bart., in February, 1833. [For mentions of its occurrence in various parts of Britain, seel. 395.; III. 436.; V. 567. 723. Lanius excubitor, in IV. 449., is wrongly introduced by myself: the author's bird was Lanius Collurio. — J. Z).] Least Woodpecker {Vlcus mhior). Two specimens were shot. It is a rare species in this locality. Little Gull {JLdrus minutus) shot. Little Gallinule {Galltnula mi7iuta) shot near Yarmouth. Gadwall Duck shot. A Black Stork {Cicbnia nigra) was shpt, in October, 1832, in the parish of Otley, about eight miles from Ipswich, in this county. I was informed of the circumstance by E. Acton, Esq., of Grundisburgh, who can bear testimony to the fact, having seen the bird, when in a high state of putrefaction, sus- E 3 5-^ Short Communications : — pended from the bough of a tree, where it had been placed by the person who had shot it. Atkinson, in his Compendium of British Ornithology^ mentions a bird of this species being killed in Somersetshire a few years since. Crossbills (Ldxia curvirostra) were shot in the same planta- tions [which are spoken of in p. 53., in the notice of the haw- finch], where they were often seen during the last winter, and generally feeding on a variety of spruce fir bearing a small cone. I have invariably found the crossbill preferring the larch to every other tree of the pine tribe, except in this instance, when the seeds of the small cones of this variety of spruce fir appeared to be their favourite food. I have seen them feeding on the common spruce fir, and occasionally on the Scotch and Weymouth pines, but seldom on the two last mentioned. Rusticus (of Godalming), in his esteemed communication (VI. 111—116.) of " More about Birds," in speaking of the habits of the crossbill, says (VI. 113.), that the idea of its " holding the fir cone in the claw, and extracting the seeds with the beak, must have been suggested by some wag to a credulous naturalist." Now, I do not in the least doubt but Rusticus is perfectly correct, as far as he may have had opportunities of observing the habits of this species, and, as he mentions the acts of individuals which he observed feeding on the Scotch pine, he may not have closely watched the movements of this species when on the larch. From October, 1821, to the middle of May in 1822, cross- bills were very numerous in this county, and, I believe, ex- tended their flights into many parts of England. Large flocks frequented some plantations of fir trees in this vicinity from the beginning of November to the following April. I had almost daily opportunities of watching their movements ; and so remarkably tame were they, that, when feeding on fir trees not more than fifteen or twenty feet high, I have often stood in the midst of the flock, unnoticed and unsuspected. I have seen them, hundreds of times, when on the larch, cut the cone from the branch with their beak, and, holding it firmly in both claws, as a hawk would a bird, extract the seeds with the most surprising dexterity and quickness. I do not mean to assert this to be their general habit ; but it was very frequently done when feeding on the larch. I have never seen them attempt the like method with cones of the Scotch or other species of pine, which would be too bulky for them to manage. Their method with these, and, of course, most frequently with the larch, was to hold firmly on the cone with their claws ; and, while they were busily engaged in this Birds, 65 manner, I have captured great numbers ; many with a horse- hair noose, fixed on the end of a fishing-rod, which I managed to sh'p over the head when they were feeding, and, by drawing it quickly towards the body, I easily secured them ; others I took with a limed twig, fixed in such a manner in the end of the rod that on touching the bird it became immediately dis- engaged from it, adhered to the feathers, rendered the wings useless, and caused the poor bird to fall perfectly helpless on the ground. In this manner, in windy weather, I have taken several from the same tree, without causing any suspicion of danger. On warm sunny days, after feeding a considerable time, they would suddenly take wing, and, after flying round for a short time in full chorus, alight on some lofty tree in the neighbourhood of the plantations, warbling to each other in low pleasing strains ; they would also fly from the trees occasionally for the purpose of drinking, their food being of so dry a nature. In captivity they were quickly reconciled, and soon became very familiar. As, at first, I was not aware what food would suit them, I fixed branches ^f the larch against the sides of the room in which I had confined them, and threw a quantity of the cones on the floor. I found that they not only closely searched the cones on the branches, but, in a few days, not one was left in the room that had not been pried into. I gave them canary and hemp seed ; but, thinking the cones were both amusement and employment, I continued to furnish them with a plentiful supply. I had about four dozen of them ; and frequently, whilst I have been in the room, they would fly down, seize a cone with their beak, carry it to a perch, quickly transfer it to their claws, and, in a very short time, empty it of its seeds, as I have very many times witnessed, to my surprise and amusement. As the spring advanced, the male birds in the plantations were frequently singing on the tops of the firs, in low but very agreeable notes ; yet they continued in flocks, and were seen in some parts of the county until the beginning of June. I had hopes of their breeding in confinement, and I accordingly kept them in different rooms, fixing the tops of young fir trees in the floor, and against the walls, and supplying them w^ith as great a variety of food as possible ; but all to no purpose, as neither those I had con- fined in this manner, nor those in cages, ever showed any inclination to breed. They are amusing birds in confinement, as they have some of the habits of the parrot tribe ; climbing about the cage with both beak and claws. Since 1822 I have seen but few crossbills; small flocks have occasionally visited the fir plantations in the neighbour- hood, but have remained only a short time. During the early E 4 56 Short Communications : — part of last winter, a small flock took up their abode in some plantations near Ipswich ; and, in the beginning of September of the present year, several specimens were seen, and one killed evidently in nestling plumage much resembling in mark- ings the young greenfinch. When every part of our islands shall have been visited by naturalists with ears alive to every note, and eyes that mark the species by the passing glance, at rest or in the distant flight, then may we expect to hear of different localities, where the crossbill may occasionally breed ; which may probably be in some of our mountainous districts ; more especially as the sides of the hills, in many parts of the empire, are now covered with rising woods of larch and other species of the pine tribe. — J. Z). Hoi/. November 28. and Dec, 4. J 833. Notices of the occurrence of the crossbill will be found in 1,394,395.; 11.89.268.; III. 176.; IV. 163. 449.; \,555,; VI. 112. In some of these places, facts are added on the food and manners of this species. From these, and the pre- sent one by Mr. Hoy, it seems that, although the crossbill may prefer the seeds of the common larch for its food, it will, in the absence of these, partake of the seeds of any species of pine, fir, or larch ; and, it is highly probable, of the seeds of any plant included in the natural order ^bietinae. Mr. Yarrell has, in the Zoological Journal, iv. 459. to 465., de- scribed, and illustrated by seven coloured figures, the struc- ture of the crossbill's beak, and the form, office, and relative action of each of the bones and muscles which subserve the bird's act of extracting and taking its food. Mr. Yarrell has quoted Mr. Townson for some facts on habits. From both authors we have learned as follows : — The structure of the beak in the two British species of crossbill, and in these alone of all British birds, is such as supplies a capability of lateral motion, and of a surprising degree of power in a lateral direc- tion. These avail the bird in the acquisition of food, thus. It first fixes itself across the cone, and then brings the points of its mandibles from their crossed or lateral position, so that they are immediately over each other. The bird then in- sinuates its beak, thus reduced in compass, between the scales of the cone, and then opening its mandibles, not in the manner of birds of other species, but by drawing the lower mandible sidewise, it forces the scales asunder. It now applies its tongue, which has at the extremity a peculiar ap- pendage resembling a cutting scoop ; this is inserted under- neath the seed, which, by it, is dislodged and conveyed to the mouth. — J, D, The Plectrophanes lapponica (VI. 482. 486.) has been cap- tured, along with Larks, near Preston, Lancashire. — As Mr. Birds, 57 John Harrop, son of the sub-curator of the Manchester Museum of Natural History, was, on Oct. 18. 1833, passing through the Manchester fish and game market, he was struck with the appearance of a bird among a number of larks. He obtained it, and it turns out to be Plectrophanes lapponica. Mr. Harrop, on dissecting it, could not determine whether it was a female or a young male ; he thought it the latter. On comparing it with the figure in Fmina Boreali- Americana, 1 should say that the figure is highly coloured; while the colours of the specimen are more brilliant than those in Wil- son's figure. The specimen is now in the Museum of the Manchester Natural History Society. The bird was taken near Preston, in this county. While writing, I would ask T. K. (VI. 519.) to examine the works of Messrs. Harrop. — J. O. Manchester, Nov. 11. Crossing and Lengthening in the Mandibles of Birds ; Re~ marks on the Causes of, and Conditions observable in, (III. 402. ; VI. 517.) — In the numerous instances which have fallen under my observation, it has always appeared to me that excess of nutriment has been the principal, if not the sole, cause ; as in every case the individuals have been in good plump condition. Monstrosities of this kind, consequentl}', are much more common among birds in captivity than birds in a state of nature : and it may be generally observed, particu- larly in soft-billed birds, that the under mandible is more subject to grow out than the upper. I have repeatedly noticed this in the redstart and robin, and have now, in confinement a pied water-wagtail, in which I find it necessary to cut off, every three or four weeks, nearly a quarter of an inch of horny substance at the extremity of the under man- dible. In a twite (Linaria montana), also, which I possess, the lower mandible grows out still more rapidly than in the wagtail, and has continued to do so for upwards of a twelve- month ; though the upper one has ever retained its natural form. In the bullfinch and in the oxeye I have known the upper mandible to increase, and not the under ; but these are the only instances. The goldfinch and the siskin are very apt to have both mandibles grow out ; one of the former, in my possession, has, at this time, its bill nearly half as long again as it ought to be, but the mandibles do not cross. An old favourite siskin, which I long kept in confinement, was a per- fect Loxia in this respect, and its mandibles became, in time, so much decussated, as seriously to inconvenience the bird. While removing the excrescence, I chanced, unfortunately, to pass the knife rather too deep ; and, though the wound was so small as to be scarcely visible, the poor little creature bled to death. I mention this as a caution to others who may find it 58 Short Communications : -^ necessary to use the knife in similar cases. When once the bill of a bird has begun to grow out in this manner, it will always continue to do so ; and, though cut, will very soon increase again ; in the instance of the goldfinch above- mentioned, the lower mandible continued to grow out for six or eight months before the upper one commenced, but both now increase equally fast. This elongation of the mandibles has never taken place in any of the numerous species of warblers (Sylvianae) which I have kept, and now keep, in cap- tivity ; though the birds of the robin kind appear extremely subject to it. Among other species, I have noticed it in the tree sparrow (Passer arboreus, Pringilla montana L.) — Edward Blyth. Tooting^ Surrey^ Nov. 26. 1 833. The crossing of the mandibles in the crossbill itself seems liable to a variation in the mode. Mr. Yarrell, in his Treatise on the beak of the crossbill. Zoological Journal^ iv. 459., has this remark : — "In some individuals the upper mandible is turned to the right, the lower mandible curved to the left ; in others, the position of the mandibles is reversed as to their direction." In continued frosts, one occasionally sees a robin, or other species of bird, with the distal half, more or less, of one, usually the upper, of its mandibles absent; broken off, perhaps by a shot, perhaps by the bird's violent application of it to the ground, then frozen " hard as a stone," to remove thence some object of food. As the portion which is left of the fractured mandible usually exhibits some bloodiness, the bird, the fate of Mr. Blyth's siskin suggests, bleeds to death. If not, it may be presumed that it must die of starvation, from its inability, from the absence of the more prehensive part of one mandible, to pick up a sufficiency of food for sustaining itself.— J. Z). Excrescences on the Head and other Parts of the Common Hedge Chanter [Acc^7itor modiddris Cuv.) (VI. 153.) — In the instances which have come under my notice, I am confident they were of extremely rapid formation. A short time since, one of these birds was brought to me, weak and exhausted for want of food ; really a hideous object, with numerous large excrescences on different parts, some of which completely blocked up the nostrils, and twisted the beak out of all form, completely incapacitating it from taking any kind of food, but which was nevertheless extremely plump and in good condi- tion. I once observed excrescences somewhat similar rise in the course of four days on the head and knee (the real heel) of a tree pipit (^aithus arboreus), one of which was very nearly as large as the head itself. — Edward Blyth, Tooting^ Surrey, Nov, 26. 1833. Entomological Society of London, 59 Entomology. — The Entomological Society of London held the first meeting, of their first session, in the evening of Nov. 4. 1833, at 17. Old Bond Street. Messrs. Kirby and Spence, the distinguished authors of the Introduction to Entomology^ and thereby the founders, it may be said, of this science in Britain, were present, and the members assembled, about fifty in number (including Messrs. Stephens, Hope, Walker, Westwood, Yarrell, Dr. Horsfield, and Col. Sykes), testified their sincere gratification at this circumstance. The Rev. Mr. Kirby, who had been unanimously chosen honorary pre- sident of the Society, and to whom the chair, first taken by J. G. Children, Esq., was resigned, stated that he would do all in his power to advance the interests of the Society ; but that he felt that, at seventy-four years of age, much would not be expected from him. He could not, however, refrain from observing, that science was indebted for the most interest- ing and valuable portions of the work to which his own name appeared conjointly as author, to his friend beside him ; and, here, Mr. Kirby laid his hand on the shoulder of Mr. Spence. The meeting elected Mr. Spence an honorary member, by general acclamation ; and Mr. Spence, in returning thanks, avowed that he came to the meeting, and had brought his two sons, for the express purpose of joining the Society. He then produced a letter, which was read by one of his sons, detailing so much of the proceedings at the late meeting of naturalists at Breslaw as referred to entomology, and with which, he said, he had been favoured, previously to leaving Paris, a fortnight ago, by M. Lefebvre, the secretary of the Societe Entomologique de France, who, as well as many others of the principal members, had expressed to him their high gratification at the institution of the Entomological So- ciety of London, and their ardent desire that a frequent inter- course between the two Societies might promote the objects which both have in view. Mr. W. B. Spence (eldest son of Mr. Spence) was then elected foreign secretary of the Society, and the members, after going through the by-laws and other routine business, separated, highly gratified at the very auspicious circumstances under which the meetings of the new Society had been com- menced. The second meeting took place on Dec. 2. " The room was considerably crowded." Some scientific communications were read. For the details, see the Entomological Magazine for January, 1834. The Society's future meetings are to be held on the first Monday in every month, and the chair to be taken precisely at 8 o'clock in the evening. 60 Short Communicatio?is : — lA Pupa of Bdmbyx mentMstri, Six Pupas of the O^phion vinulte, and a Pupa of Bdmbi/a: vinulus, all found in company mthin^ and bred from, the hard Cocoon of the Bombi/a: vinulus. (IV. 267., V. 592., VI. 378.)] — In p. 378., I forgot to give the extracts from Dr. Leach's and Mr. Kirby's letters about the ophions and 56mbyx menthastri that were found in company within the cocoon of ^ombyx vinulus. Mr. Kirby says : — "I shall be glad to learn whether the pupa you found in vinulus turns out lepidopterous, as it will furnish a new circumstance in entomology, if it so turn out." (Dated May 22. 1820.) Dr. Leach says : — " Respecting the ichneumon, the fact of six being found in one pupa, and a lepidopterous insect within, is very curious, and quite new to me. I have found one, frequently, in the form of pupa, within the perfect pupa of a Cossus, which must have entered in form of egg deposited by the parent." (Dated March 10. 1820.) The ^ombyx menthastri bred June 8. 1820; but the ophions did not appear till the 28th. The larva of ^ombyx vinulus I took at Whitdesea Mere, July 24. 1819. Another person has said there must be some mistake ; but I can assure him it is a fact, although I cannot account for it. — J, C. Dale. Sept. 1833. An Instance of Variation in Shape in the Upper Wings of two Males of the Lycce'^no. dispar. — Mr. Kirby has said, — " Colour, I believe, often varies in Lepid6ptera, but I cannot think that shape does." Now, I have taken two male speci- mens of Lycae^na dispar, near Trundle Meer, in Hunts, in which the outline varies much ; the upper wings of one being long and acute, the upper wings of the other short and ob- tuse; but in no other respect do they vary. [A sketch, which accompanied this communication, exhibited a very obvious degree of variation. Mr. Dale has drawn the outline of the smaller within the outline of the larger.] The second dot in the upper wings [exhibited in the sketch] always shows more or less in Lycae^na dispar male, but, I believe, never in L. Hippotho^ male. (Is it quite true that L. Hippotho^ is British ?) Ediis« varies the same. — Id. Cordulia Curtis'n Dale, a Species hitherto undescribed, cha- racterised by Mr. Dale. — On June 29. 1 820, I discovered a new Cordulia on Parley Heath, Hampshire. It is one of the finest insects I have ever found ; and I had proposed to name it after a certain friend, but objection has been made to its bearing his name, " he not being the captor." As it has remained a nondescript up to this time, and is unnoticed, so far as I can find out, by Vander Linden, Charpentier, and other writers, I now venture to describe and name it after a friend whom I saw capture it: and, as some jealousy has Injects. 01 been displayed on account of my having given a manuscript name only to Halictophagus CurtiszV, I request the favour of the following appearing in print : — Genus Cordulia Leacli^ &c. ; Libellula Xzw., &c. Species CurtiszV Dale. Viridi-senea ; abdomine medio flavo-maculatis ( $ compresso et alis flavescentibus.) Habitat: Parley Heath, Hants, in June, J. C. Dale : Ramsdown, Hants, in May, J. Curtis, Esq. ; Braunton Burrows, Devon, J. Cocks, Esq. About the size of C. ag^nea. Brassy green ; body compressed, with a row of oblong yellow spots down the back, absent on the 7th and 8th joints only ; head notched in front : wings very pale greenish yellow, slightly yellow at the base in the male; yellow- brown in the female, along the costa of all the wings, suffused to their centre ; stigma and nervures piceous. The above is sufficient, I believe, to distinguish it from all other species at present known ; but I hope my friend Curtis will now be enabled to give us a figure and a better descrip- tion, without having his modesty called in question by being gratuitously made subject to the imputation of his naming an insect after himself. — J". C Dale, Sept, 1 833. Of the Genus Oxycera Mr. Dale and myself have [in 1832] succeeded in making out eight or ten species (I beheve only three have been noticed by Mr. Stephens), and we are yet in hope of discovering more ; although at Pinny Cliff, near Lyme, where I first discovered one new species last year, they are extremely local, and almost confined to one or two trees. — Francis Or pen Morris. Charmauth, Dorset, Sept. 1832. Two Facts on the Dung-jiy [Scatophaga stercordria). — I have frequently found this insect, when dead, firmly attached round the stem of an ear of corn, &c., and its body here and there covered with a white dust resembling mould. During last year, 1832, I met with only one example; but, during the previous year, I must have noticed a hundred at least. They are fixed in precisely the attitude of life, as if only resting for a short time ; and, from this appearance, may have escaped general observation. While standing (in 1832) under an oak tree at Hamp- stead, something fell down from the boughs upon the grass, in which it produced a loud humming noise. I searched for it, and found it to be a common bluebottle fly, spinning round upon the earth, and uttering that peculiar buzz which it makes when struggling with a spider ; and firmly attached to it was a dung-fly, which was rather reluctant to loose its hold : before, however, I could open a pill-box to receive them, they had separated, and flown off in different directions. What could be the purpose of the attack ? — James Fennell, 62 MISCELLANEOUS INTELLIGENCE. Art. I. Retrospective Criticism, Observations on Classification^ in reference to the Essays of Messrs. Jenyns (VI. 385.), Newman (48L), and Blyth (485.). — Sir, The two great defects of modern systems appear to be, the want of simplicity and of uniformity ; and I cannot but think that both these may be in great measure attained, with- out any violence being offered to the " natural system." Mr, Jenyns (VI. 385 — 390.) appears to have blended together two distinct causes of complaint : first, that in modern systems genera are founded upon characters of un- equal value ( differs from the common one only (I believe) in being of a darker colour ; and is, therefore, deservedly considered a variety. — H, E. Strickland. Nov, 22. 1833. The Black Viper. (VI. 527.) — When E. N. D. says (VI. 526.) " there is but one species of viper or poi- sonous reptile in England, he forgets the black viper (Co- luber Prester of Linnaeus) ; to the existence of which, in the west of England, Mr. Blyth also alludes doubtfully, in VI. 527. Of this species, I have seen, at different times, alive and at large, two specimens in the Isle of Wight, one of Retrospective Criticism. fj which I succeeded in killing on Oct. 12. 1804. I was, at the time, in company with a gentleman resident in the island, who seemed to be familiar with the reptile, and informed me that it was very venomous ; of which fact I entertain no doubt. " Os armatum est veneno diro," observes Linnaeus, in Fawia Suecica; he gives, as a synonyme, " Vipera anglica nigricans " of Petiver : the animal, therefore, has long been known as a native of England. On a transient view, this species appears entirely of a uniform deep black colour, as described by Linnaeus, " ater toto corpore ; " but, on closer inspection, a row of angular spots, similar to that on the back of the common viper (C J5erus) is discernible, being of a still more intense black than the rest of the body. Li size, shape, manners, and habits it seems exactly to resemble the common species ; of which, 1 think, I have heard that it has been sometimes considered only a variety, and from which I am not aware that it differs, except in colour. The red viper, mentioned in VI. 399. 526., I should suspect, was only the young state of the common species ; the smaller specimens of which, I have observed, are generally of a brighter colour than the full-grown ones, and have the spots more inclining to red. — W. T, Bree, Alleslej/ jRectory, Nov. 6. 1833. Leptocephalus MorrisVi Pennant (V. 313. 7*2., VI. 531.) seems doomed to be never accurately represented by the engraver. The cut, in VI. 531., which professes to be a copy of my drawing, is defective in one most essential point : the engraver has neglected to represent the pectoral fins, and has rendered the lateral line too strong. The engraving, with these exceptions, is very like the fish. —Henry Vietz Deere. Nov. 15. 1833. The Authorship of the Prefixes, ^;ro, meso, and meta, to the Limbs of Insects belongs to Mr. Newman ; not to Mr. Haliday. I observe that Mr. Westwood has appended to some techni- cal descriptions in VI. 495, notef, a remark expressly for the purpose of depriving Mr. Newman of the merit of the above prefixes, and of giving the said merit to Mr. Haliday. Mr. ^e^m^njirst published the names in question at p. 400. of the E7itomological Magazine (July 1. 1833). Mr. Haliday has nowhere published them, that I can find. Indeed, at p. 516. of the same magazine, published three months subse- quently (Oct. 1. 1833.), he follows Meigen, in applying the term metatarsus to the last articulatiorj of the tarsus ; so that it is evident that Mr. Haliday not only did not originate these terms, but declines employing them. — Lacon.

T. Bree. Nov. 6. 1833. Encrinite versus Cyathocrinite (VI. 560., and the pre^ vious Discussions there indicated). — A few additional words appear necessary to set myself right with Mr. Gilbertson. I cannot exactly comprehend Mr. Gilbertson's description, at p. 561. He says, " the line of dots from a terminates at the alimentary canal ; that from b, upon one of the five plates sur- rounding it, which form the pelvis ; c is placed upon the costals," &c. Now, according to this description, I find (as I am able to understand it) that the pelvis, in this specimen, formed a circle of less circumference than the vertebral column, and, consequently, was entirely hid by it. Is this fact, or is it error ? Is this ever known to be the case in any crinoideal animal? It is not the case in any of those figured or described by Miller, nor in any instance that has come under my own immediate observation. Mr. Gilbertson pro- ceeds to say, that, in my figure, " the whole of the pelvis, and nearly the whole of the costals, are hid by the column." This, I presume, is erroneous : if the enlargement of the column, in my specimen, is natural, and not formed of extra- neous matter, I think the above statement of Mr. Gilbertson would not be in accordance with the facts in our possession upon the subject. Does it not always follow, as a matter of course, that, where the column is enlarged and expanded at its junction with the pelvis, the pelvis is also widened and enlarged in the same proportion ? as in the genus Apocrinites. This, I think, cannot be denied. The relative size of the bones, in my specimen, will, I think, prove that this opinion of Mr. Gilbertson is not tenable. The scapula (according to Retrospective Criticism, 7S> Mr. Gilbertson^s idea), which he describes as being in its pro- per place, in my figure, on the left of the column, is nearly as large as that part of the column which I have supposed to be extraneous. This scapula must rest upon a costal, and this costal upon a pelvic bone, or rather upon two pelvic bones ; the costal upon which this scapula rests must be as large as the scapula itself; and the pelvic bones upon which the costal rests must be of equal dimensions : therefore, if the scapula be nearly equal in size to the column, the sca- pula, costal, and pelvis, united, must of necessity be much larger ; and yet Mr. Gilbertson says, that, in my specimen, the column hides nearly the whole of these bones : this is a physical impossibility, for the thing covered is of greater magnitude than that which is said to cover it. Again : that the angular bones, in my specimen (VI. 126.), and to which I have referred in VI. 472., are really the bones of the pelvis, is, I think, absolutely proved by their position. The costals are placed upon the pelvis, I believe in every instance, in this way : one costal rests upon part of two pelvic bones, and covers the joints formed between them ; and thus locks them together, precisely in the same way as a bricklayer places one brick to cover portions of two others, in laying one course over another, in building a wall : and this is exactly the position they occupy in my figure. If this bone were the scapula, the angular bone (the costal of Mr. Gilbertson) must have had a joint in the angle, in a line with the joint between the supposed scapulae ; but in my figure there is no such division. If the column absolutely '' covers the whole of the pelvis, and nearly the whole of the costals," it appears to me difficult to account for the use of the pelvic or costal plates ; for by this means they would be united into one solid mass, and, therefore, their division into plates would appear to be almost useless. In conclusion, Mr. Gilbertson accuses me of constnicting a nondescript. Whether he means this in good part or not, I can hardly say. I have already acknowledged that, in my opinion, it had not " hitherto been figured or described ; " and it was because I considered it a nondescript that I communicated it to this Magazine, and endeavoured to furnish a description of it. If nothing is to be made public but what is already described, then must science have already reached its limits; and the naturalist may sit down in listless- ness, and exclaim, " There is no new thing under the sun ! *' Mr. Gilbertson sums up his observations by stating, that it is a desire to check the progress of error that alone has induced him to controvert my statements ; I beg to inform him that there is no other motive influencing me. I am not at all anxious to prove that I am in possession of the lily encrinite 80 Queries and A?iswers, from a new locality, and to make my specimen a lily encrinite, whether or not; for this would be mere childishness. The fact is this : the remains of a crinoideal animal fell into my hands ; I fancied it to be more nearly allied to the genus Encrinites than to any other; this opinion I have given; I have given my reasons for that opinion ; and I have defended it : whether that opinion be right or wrong, others must judge. That it is a nondescript is no fault of mine ; I have argued for its being such : and, if Mr. Gilbertson would, in some way, publish figures of his specimens, which "have a much greater claim" to be considered as encrinites than my specimen, perhaps the other opinion which I have stated (VI. 474.), that the encrinites pass by a regular gradation of form into the cyathocrinites, would receive additional confirmation, if not full proof. Mr. Gilbertson says that both specimens are the same ; that is, that mine is Cyathocrinites tuberculatus. This is impossible : the name itself contradicts it. There is not a single tubercle upon my specimen : it is almost as smooth as the paper upon which I am writing. Mr. Gilbertson has not noticed the relative proportions of the bones which I have pointed out in the different specimens. I should be extremely glad to be put in possession of figures of the specimens mentioned by Mr. Gilbertson ; and I think he would be doing the world a service by publishing them. Let us be put in possession of as much knowledge as possible, in order to come to a clear understanding of these singular animal remains. — C Conway, Nov.l2.lSSS. Art. II. Queries and Answers. " On the supposed Connection of Vicissitudes of the Sea- sons and prevalent Disorders with Volcanic Emanations,'" Sfc. (VI. 289 to 308.) — Although the author (the Rev. W. B. Clarke) of that interesting communication does not posi- tively maintain a closer connection between events which are apparently dissimilar than that of juxtaposition, I think he has established a high degree of probability that the connec- tion is that of cause and effect, in numerous instances which he has adduced. I propose, at a future time, to offer a few observations on some of the facts stated by Mr. Clarke, my object in the present letter being merely to request farther information from that gentleman respecting the " symptoms of renewed action in the extinct craters of the Eifel ; " and, again, " symptoms of renewed action in the extinct craters of Auvergne." (VI. 301.) The date of the latter is given Dec. 9. 1828; but no authorities for either event are stated. It would Queries and Answers* ^1 greatly oblige me if your ingenious correspondent would state the circumstances which have been called renewed symptoms of action more fully, and also the authorities by which they are supported. It could surprise no one who has attentively examined the extinct volcanoes in central France to be in- formed that they had broken forth into renewed activity after a period of repose of many hundred, if not thousand, years. Vesuvius is known to have had periods of repose for many centuries ; and the lava of some of the volcanoes in Auvergne appears as fresh as if it had been very recently erupted : in- deed, it is very difficult to conceive how it could preserve such a fresh appearance after exposure to the atmosphere for ages. In my Travels in the Tarentaise, published in 1823, I stated that " there is nothing in the appearance of the volcanoes of Auvergne which can lead the observer to the conclusion that their eruptions will never be renewed : the springs of hot water in this district indicate that the source of subterranean heat beneath it is not extinct. The most abundant and best known of these springs are Mont d'Or and Vichy ; they have a tem- perature of from 120° to 125°; and there are many other springs of equal temperature. Should the volcanoes of Au- vergne resume their activity, such an event would not be at variance with our present knowledge of volcanic operations." (vol. ii. p. 379.) Many of the eruptions in Auvergne must have taken place in a recent geological epoch ; for lava has flowed into the present valleys, and the heaps of fresh scoriae that are spread loosely, near the mouths of the craters, and volcanic vents to which they can be traced, prove that the country has not been since subjected to diluvial currents, for these would have swept them away. They prove, also, another fact of some interest : many of the most recent eruptions appear to have taken place from volcanic openings, which were closed before craters could be formed round them ; for, had craters been formed, and afterwards destroyed by inundations, the same causes would have removed the lava and scoriae. In other instances, volcanic craters v/ere formed by repeated eruptions, and remain nearly perfect to the present time. The occurrence of volcanic mountains, over a space of several thousand square miles in central France, should induce us to receive with caution the accounts of the increase of temperature in Artesian wells in PVance, at a rate of about 1° of Fahrenheit for every 45 ft. of depth ; for this increase may depend on local causes, which may not extend into other countries. It is greatly to be regretted' that few experiments on the temperature of Artesian wells have been made in Eng- land.

In that sequel, Mr. Bakewell's queries and suggestions will, we are certain, receive Mr. Clarke's best atten- tion. In the meantime, we are quite sure that Mr. Clarke will concur with Mr. Bakewell in soliciting all possible information on the temperature of Artesian wells, and on any point in the subject under consideration, from any correspondent. — J.

I believe this to be an old plan, and an effectual one. < — James Fennell, Polyommatus hlexi?>^ I^carus, and Icdrius. (VI. 544.) — In reply to Mr. Conway, I must observe that Polyommatus Alexia of Stephens is P. I'caru5 of Lewin, Haworth, and others. Accordingly, no species is enumerated under the specific name of Fcarus by Stephens nor by Wood ; each of these authors, however, gives P. Icarius as a species, though the former, at least, doubts its being really distinct from P. Alexis. " It approximates," says Mr. Stephens, " so very closely to the following species [P. Alexis], that, I conceive, it will eventually prove a mere variety of that insect." Pro- bably the similarity between the names of I^carus and Icarius has misled Mr. Conway. I cannot but join this gentleman in his regret (VI. 542.) that the under sides of more of the Papi- lionidae are not figured in V^ood's Index Entomologicus : " a deficiency greatly to be lamented," and one which, I hope, may yet be supplied.

Querist, however, means the distinctive features of the insect's external anatomy, as compared with those of other recog- nised species of Fespa: this question stands with entomo- logists. — J, D. 83 REVIEWS. Art. I. Catalogue of Works on Natural History ^ lately published, tvith some Notice of those considered the most interesting to British Naturalists* Bylandt, Le Comte de: Resume Preliminaire de I'Ouvrage sur la Theorie des Volcans. pp. 50. Naples, 1833. This " avant-propos " details a forthcoming work in 4 vols, with plates, the result of more than thirty years' researches into the causes and effects of volcanic phenomena. If the work fulfil the expectation which this bill of fare induces, the author need not despair of being rewarded with the title of " laborious'^ But it cannot be supposed that, till we have perused it, we should recommend the adoption of the views which it contains, some of which we can hardly appreciate from this preliminary abridgment. It shall be our business, however, to dissect hastily and briefly these fifty pages of prospectus : — The groundwork of M. de Bylandt's reasoning process are the principles, that accurate observation is the basis of truth in science, that every thing in nature has an ordained end and object, that nothing happens by chance, that there are an equilibrium and a harmony between all the divisions of matter, and that there is neither increase nor decrease in its composing particles, (p. 1 — 7-) These principles are next applied to the doctrine of volcanoes, (p. 8.) To in- vestigate these, he is led to consider the doctrine of the elevation of mountains, (p. 11.) . This elevation our author attributes to four causes^ sometimes isolated, sometimes united. The eruption of the central fire {feu igne central) at " the beginning ; " the sinking down of the mineral crust after its stretching to the top of its elasticity ; the " eboulement " of a part of the strata into profound depths, produced by the pressure of waters, which explains the obliquity of contra- dictory beds in the same mountain; and the lifting up of the outer crust by interior pressure in the direction of certain radii of the globe, when the diminution of the central fire could only elevate those points which offered least resistance, to which is attributed the vertical direction of certain rocks and strata. o S 84 Bylandfs Resume Preliminaire de VOwvrage To investigate this, the author visited all the mountain chains of Europe, from the Caucasus to the Pyrenees, the analysis of the latter of which, during two summers, he com- pared with the studies of nine consecutive years amongst the Alps. There he observed the play of the elementary fluids; and noticing that the mountains possess a particular attrac- tion from the west, declining to the south, and that it is imper- ceptible to the east, and null towards the north, he discovered that the electric fluid constantly follows the sun, rises with him to the zenith, sinks with his rays, and disappears in his absence, (p. 12.) This phenomenon attaches only to moun- tains of the second and third classes as to height; for in snow-clad mountains an electric current is perceptible from N. to S. at from 7000 to 8000 feet, corresponding to the latitude of from 60° to 70°. Now, the aurora borealis shows that this fluid there abandons the globe, and therefore it ought to bend from N. to S. at an angle of 45°. The tables given by Franklin and Back show that the aurorae which appear between 60° and 70° cease at 70°, and their axes are directed to the S., reappearing at the equator, at the height of 17,500 ft., under the name of the zodiacal light; which exactly agrees with the inferences derived from the currents in the polar seas, whose influence diminishes inversely with the angle of direction, ceasing at 55'^ N. and 40° S, Hum- boldt remarked the force of electricity at the height named ; and M. de Bylandt on Mont Blanc, at 8700 ft., which cor- responds therewith the latitude in question, (p. 13.) M. de Bylandt then states, that in 1818, at the height of 20,700 ft. under the equator, which correspond with 10,500 ft. of Mont Blanc and 85° N. lat., the caloric had not enough activity to form ice, but that above there was nothing but perpetual snow. Parry, Heemskerke, Franklin, &c., are brought in to show there is a great correspondence between the glaciers of the Alps and the Polar Sea.* It seems that our author compared his calculations with Captain Back's at Naples, and also in London with those of Parry and Franklin, and that the results were wonderfully coincident^ so that be assumed the magnetic pole from 81° 57' to 83° N. * Of this the writer of these remarks has no doubt. The coast of Greenland was first frozen up in the year 1348 (the year of the " black death"), and in 1817 (the year of the cholera) that coast began to be disengaged. Now records attest that, previously to 1348, a straight path lay over Mont Blanc, where now the glaciers are, into Italy; and it is known that recently there has been a diminution of ice and snow on the same mountain. This is not the place to avail himself of the deduction he wishes to draw ; but these facts correspond with the observations of M. de Bylandt. — W, B, C, 5wr la Theorie des Volcans. S3 discovering that on Chimborazo the magnetic power ceased at 20,700 ft. corresponding with 10,500 ft. of Mont Blanc, and the level of the sea at 83° N. lat. (p. 14.) Captain Ross has recently determined the magnetic pole to be more south- ward, in lat. 71° — 72°. But this by no means throws over all the count's arguments. Our author proceeds (p. 15.) to treat on the fluids by whose separation matter was originally developed: — 1. The ethereal universal fluid ; 2. Caloric. 3. Light ; and, 4, 5, their auxiliaries, the electric and the magnetic fluids ; lastly, that fluid which is combined of all, X)olca7iic Jire, Under these impressions he investigated the course of natural phenomena, and the results will be laid before the public in the forthcoming work. Some of them we state here. The parallelism of volcanoes is the first: they never appear isolated. The fluids above-mentioned depend on the sun; and their influences cease at 80° N. and 65° S. The points of intersection of the equator and the ecliptic are correspondent with similar points of intersection between the equator and the course of the volcanic fire, the latter of which are visible ; the line of junction of these points making an angle of 5° with the earth's radius, and this angle being the constant measure of the divergence of all the vol- canic radii, horizontal or vertical. (There is some difficulty in understanding the count's meaning in this place, arising from a want of perspicuity.) But he states that the slopes of the summits of volcanoes, opened by the flow of lava, are all towards the equator, with a trifling inclination to the west, (p. 17.) He next assigns to the Gulf of Mexico, as M. de Humboldt has done before, the central seat of volcanic fire, taking the correspondent inverse focus to be in the Archi- pelago of the Molucca Islands. Forming a circle on the volcanic equator round these islands as a centre, and dividing it into segments of 10°, he found that radii drawn through these points passed through the lines of direction, and to the limit of all the volcanoes in the globe. 1st, to 90°, passes by the Philippine Islands, Manilla, and China. 2d, to 80°, follows a nearly similar course. 3d, to 70°, commences at the Isle of Niphon and finishes at Japan. 4th, to 60°, forms the chain which passes through the Kurile Islands and ex- tends to Kamtschatka about 70° N. lat., which with Iceland and Jan Mayen's Island (about 70°) seems to limit the vol- canic action to that latitude. 5th, to 50°, passes by Ma- gellan's Island to Behring's Strait. 7th, to 30°, forms the volcanoes of the Marian Islands. 8th, to 20°, forms the vol- canoes of the Caroline Islands. 9th, to 10° extends to the Sandwich Islands, (p. 19.) G 3 86 Bylandt''s Resume Preliminaire de VOuwage The same division is made from the Gulf of Mexico as a centre, and a similar result obtained, (p. 20.) The cur- rents of the ocean are attributed to the volcanic action, which is said to correspond exactly with the lines of magnetic and aerial phenomena, (p. 22.) The author flatters himself that he has discovered a volcanic canal flowing round the globe between two parallels, and concludes that volcanoes are like knots on a string, which must partake any shock commu- nicated to either extremity (p. 24.), quoting his examples from the known localities, (p. 26.) He next proceeds to examine the nature of the volcanic fire, which, he says, is purely material, arising from infiltration and fermentation (p. 26.) of gases, and water, and the mate- rials of the strata it traverses ; these being dissolved, com- bined, and reunited. To volcanoes acted on by the sea, the author attributes the great partial catastrophe which has desolated our hemisphere, and which, by the junction of the two oceans, under the name of the great cataclysm (the deluge), has produced the diluvial effects which the earth exhibits, (p. 28.) He explains by this means the currents directed towards the west, and the immense ravages in the coasts of the continents of Africa, America, and Europe, and the separation of the two former quarters of the globe, once united, as proved by the traces of African civilisation in Mexico, (p. 30.) The elevation of mountain chains is also made to result from this cataclysm^ and the Pyrenees are quoted as the example, (p. 31.) M. de Bylandt next classifies volcanoes into — I. Sub- marine ; II. Volcanoes " a de convert ; " which are subdivided into — 1. Direct volcanoes, situated on the great canal; 2. Indirect, on the extremities of the lateral branches ; 3. Vol- canoes in permanent action ; 4, Extinct or mud volcanoes ; 5. Volcanoes of air ; 6. Volcanoes of smoke ; 7. False vol- canoes, or simply burning hills (such, we suppose, as the cliffs near Weymouth), (p. 32.) A long illustration of another position follows, namely, that the size and height of volcanoes are proportioned to the force of the volcanic fire and the depth whence it rises. The formation of volcanic cones is next mathematically shown by a system of triangles upon the base of the volcano, and the height of the cone and depth of the crater proved to be pro- portionably determined by a general law, whilst the depth of the crater is made to be a third part of the primitive height of the volcano, (p. 35.) Here, again, we are a little at fault. Vesuvius is the subject of the experiment to exhibit the truth of these theories. sur la Theorie des Volcans. ^f A singular fact, before pointed out by other writers, is next commented on ; viz., that all volcanoes to the north of the equator have all their orifices to the west, and constantly discharge their lavas to the south; while those to the south of the equator as invariably follow an opposite direction, (p. 35.) Strombolo being an exception, the author accounts for it by assuming that the great cataclysm removed the original crater and made a breach lower down in the N.N.W. side. The action of the ejected materials is said to be spiral in the crater, and the parabolas described by the projectiles to be from an axis turned to the south, (p. 37.) Tlie exciting cause of volcanic action is attributed to sea water finding its way to the fermenting matter, producing increased heat and dilatation of gases ; the change being proportioned to the calibre of the volcano, and when it exceeds this destroying the volcano, (p. 37.) This spiral motion of the materials in action may, perhaps, be borne out by the circular motion in earthquakes ; but M. de Bylandt does not allude to it. A second cause of excitement is attributed to atmospheric air rushing down so as to produce regular respirations. The deto- nations are refen'ed to the noise occasioned by the separation of the molecules in the rocky masses acted on, and the evolu- tion of hydrogen gas, combined with electric shocks, (p. 38.) The flow of lava is said to be uniform, and to follow the direc- tion of the axis of the crater ; and examples are quoted where lava streams have been diverted from their direction, by walls at an angle ; as in the case of the eruption of 1 669, when the garden wall of the Benedictine convent saved the city of Catania. In 1831-32, the author also tried the experiment, and says that it is possible, by taking advantage of the slowness of the current, to prevent its ravages, (p. 39.) We have no space for the calculations of the author on the heights and forces of volcanoes : but we may mention that he divides lavas, as follows, into seven classes : — 1. Lithoid ; 2. Compact ; 3. Trachites ; 4>. Basaltic ; 5. Obsidian or vi- treous ; 6. Scoriae ; 7. Pumice. He, moreover, adds, that the materials differ according to different situations and dif- ferent epochs of each. (p. 42.) Such are the principal subjects to be discussed in M. de Bylandt's work, of which the ^^ avant-propos" gives an out- line. The first volume is to contain an introduction in con- nection with La Place's theory of the world, ending with an account of the causes and effects of the currents o^ the sea and the trade winds, and Captain Franklin's tables of magnetic phenomena, (p. 43.) The second volume is to em- brace the effects of water in motion, the parallel betw««n the G 4 88 Bylandfs Theorie des Volcans, Alps and the Pyrenees, and the application of the theory to the volcanoes of Europe, commencing with Sicily ; noticing, also, the circumstance of the decreased action of volcanoes in extent of country affected being counterbalanced by the pro- portionate increase of force. Etna and Vesuvius are also to be carefully considered, (p. 46.) The third volume is to con- tain the volcanic history of France, Dalmatia, and Italy. The fourth volume is to treat of the branch of the counter- current which passes under the Gulf of St. Euphemia, in lat. 39° N., embracing Calabria, &c., and concluding with an analysis of all particulars connected with Vesuvius, (p. 47.) A classification of the operations of volcanoes is also added, in eight distinct portions: — ]. Real eruptions. 2. Demi- eruptions. 3. Eruptions in the radial lines. 4. Partial erup- tions from interior galleries. 5. Interior eruptions not ejecting lavas. 6. Eruptions of water, cinders, and mud. 7. Lavas of reconstruction. 8. Emanations of inflammable gas. A body of maps will be appended, to illustrate the subject, drawn up after careful surveys and accurate comparison with undoubted authorities. Such a work, if properly accomplished, must be an acqui- sition to science ; and, for the facts introduced, must be valu- able. Of the opinions or theories of M. de Bylandt we cannot here speak; ihehrochure before us is but a concise abridg- ment by way of prospectus, and we have given attention to it in this second ^^ Resume Preliminaiy-e,^' in the hope of calling the attention of our readers to an interesting subject, on which we have at present no positive information ; volcanoes being, like comets, subject hitherto to as many speculations as there are investigators. " Quot homines tot sententiae.** Count Bylandt adds another to the list of commentators, and if his doctrines obtain the weight he attaches to them, he may indeed exult in his proof of the epigraph on the present pamphlet : — " There are more things in heaven and earth Than are dreamt of in our philosophy."

Hamil- ton & Co., London; Knight, Leeds; 1833. The date of publication of this book marks an epoch in the progress of natural history in Britain. One of Euclid's postulates is, " a circle may be described from any centre, at any distance from that centre:" so, in nature, there is not an ol3Ject which may not become the centre of a thousand associating circumstances. The systematist encircles every object with a series of considerations on its affinities and distinctive characters ; the economist, with his calculations on the answers it will bear to his grand testing question of cui bono P the sentimentalist, with his halo of "pleasing thoughts and kindly emotions;" others with other considerations, but none with evil ones ; for, as Sir James Edward Smith has said, " in nature, all is elegance and de- light ; and none but the most foolish or depraved can derive any thing from it but what is beautiful, or associate with its lovely objects any but the most amiable or most hallowed images." Thus far good and true ; and it only remains that each party perceive the propriety and the duty of depre- cating, in spirit and in practice, that exclusive feeling, which, if not deprecated, would lead him to deem the circle de- scribed by the student of a taste distinct from himself, less noble in diameter than the circle which he himself describes. This premised, it is time to state that the volume before us is one filled to overflowing with a collection of the " pleasing thoughts and kindlv emotions" which sentimental naturalists have, from time to time, encircled around, and associated with, certain and many of the innumerable objects of nature. Sentimental naturalists, at least those of them who have de- scribed the feelings and ideas which natural objects have excited within them, have been fewer; have awakened into action later; and, consequently, have fewer followers, admirers, and pupils, than other students in nature, who have been longer in the field, and have, by their more multiplied researches and discoveries, rendered themselves more rich and more capable of enriching others of tastes congenial to their own. The present little volume shows something, a good deal — for, per- haps, two more such volumes would hold all — of what has been done in sentimental natural history; and the reason why we think that it marks an epoch in the progress of natural history in Britain is, that it is significant to see the teachers in the sentimentality of natural history so numerous as this little volume shows them to be, and the day arrived when the (other or) precursory branches of natural history have been so 90 Jar diners Natural Histori/ of Humming-birds, familiarised " to the business and bosoms of men" as to make it safe to risk the expense of publishing a volume of sentimental poems, and scraps of poetry, on the objects with which natural history acquaints us.

Stuffed specimens, and the plates of M. Lesson, in his work on the Trochilides, most of these probably derived from stuffed specimens, are the main sources of the figures. In the existence of this case, we presume it is necessary to associate with the pictures the consideration of the possibility of error in the attitude, and symmetry of disposition of the parts, of almost every bird. Indeed, we have learned that the birds are placed on the branches in a very faulty manner. In the pictures, their feet and legs are ob- vious enough. In life and nature, when the birds are upon branches, you never can have a view of their thighs or legs ; and, at the very farthest, you can only now and then get a sight of their toes. A remarkable feature in the humming- bird is the shortness of its legs, which are always concealed in the thick and puff-like plumage of the abdomen ; so that, when the bird is sitting or flying, you can never see its legs; and the only means to get a view of them is catching the bird itself. The spirit of the text is the names, synonymes, dimensions, proportions, colours, structure, and systematic affinities of the species; but is devoid of those poetical notices of habits which, in a treatise on such lovely creatures, we can but wish were supplied. At the end of the volume there is a systematic synopsis of the species of humming-birds, with their names and distinctive characteristics. The memoir of Pennant, pre- fixed to the volume, imparts much useful information. The frontispiece is a portrait of Pennant. The Natural History of Humming-birds, notwithstanding the qualifying considerations which we haxe, suggested to apper- tain to its merits, will, we conceive, conduce to two excellent effects. It will lead general admirers of the forms and hues of created beings to examine them in the spirit of the science of natural history, and thus extend that science; and the work will, at the same time, become a point to which those of British naturalists who may have opportunities to supply Lauder and Broivrt's Natural History of Parrots, 91 corrective and additional information may refer it, until a more perfect history can be produced from the materials thus accumulated.

Edinburgh, London, and Dublin, 1833. 6s, The contents of the volume are, a chapter on the physical characters of parrots, a chapter on the intellectual and imita- tive faculties of parrots, a chapter on the geographical distri- bution of parrots, and, then, descriptions and coloured figures of thirty-five species of parrots. At the end of the volume are illustrations of the terminology used in describing birds ; at the beginning, a portrait and a biographical sketch of Audubon. In the commencement of the enumeration of physical cha- racters, " the toe of the parrot is made to tread" somewhat " too near the heel of the courtier ;" for there is grave talking about an analogical connection in structure between man, monkeys, and parrots. The rest of the " physical characters,*' although they are not sorted into the most orderly succession, nor unclogged with some repetitions which betray crudity, are worthy of regard, and of a proportion of the book's price. The dissertation on the " intellectual and imitative facul- ties of parrots," we leave to — to whom ? — It may be dis- respectful to our grandams to say. The *' geographical distribution of parrots" is inane enough. In the pictures, prodigious capacity of claws is given to some of the birds ; most of them grasp, as a perch, a tree with ease. Plates 14. 9. 29., and some few others, are more con- sistent with common sense in this particular. It is needful that the reader pay attention to the dimensions of each bird as set down in the text; for, in the pictures, one of 6 in. in length is pretty well of the same magnitude as one of 2J ft. or 3 ft. Birds have great versatility of neck, we know ; and we presume that plate 13. is an illustration of an extreme instance of this versatility. Various Contributors : The Entomological Magazine.

This number completes the first volume of the work, and has a full accompaniment of titlepage, indexes, errata, &c., together with " a list of the genera and species described in the volume, for the purpose of labelling cabinets." All these things seem given, that is, supernumerary to the quan- tity of pages assigned to a number. With this number, which completes the first volume, price 185., there is also given an appeal " to all lovers of natural history, all lovers of science, all who have the welfare of entomology at heart," to afford, by the purchase of the first volume, those who have originated this work and advanced, voluntarily and for the sake of science alone, their responsi- bility for its pecuniary support, " the means of continuing their exertions, and prosecuting their undertaking." This appeal we are happy to be able, on the best authority, to state has not been made in vain. Owing to the liberal support advanced by a few true naturalists, there is now no prospect of the cessation of the Entomological Magazine, This is gladdening news. No. VI., for January, 1834- (the first number of the second volume), will and does (for we have been shown the land of promise) contain the following communications ; — 1.

Four lovers of nature, of natural history, entomology, and the Entomo- logical Magazine, are made to discourse much (12 pages), and merrily, on men and things thereto appertaining. — 2. Mo- nographia Chalcidum ; by F. Walker, Esq. F.L.S. In this contiimation of the monograph (from vol. i. p. 446.), the fa- milies Leucopsidae and Chalcididae are described. The first includes but the genus Leucopsis ; the second, seven genera. The characters of the genera and species are given in great de- tail, and numerous synonymes are cited. Mr. Walker describes several species from the neighbourhood of Paris, communicated by M. F. de Laporte, and some derived from the Island of St. Vincent, taken there by the late Rev. Lansdown Guilding (p. 13. to 39.). — 3. Capture of Insects at Burghfield ; by the Rev. C. S. Bird, M.A. F.E.S. This is a most interesting com- munication. Mr. Bird supplies a list of those of the species of insects, not quite common, which he has captured during ten years' residence at Burghfield. He has been most successful in the order Lepidoptera. " This success I owe to the use of a lamp to attract moths. During the moonless nights of summer, I sit with a sinumbra lamp, and perhaps one or two smaller lamps, placed on a table, close to the window. The moths speedily enter the room, if the weather be warm. I have had a levee of more than a hundred between the hours of ten and Entomological Magazine. 93 twelve. In the spring, too, and autumn, I have been frequently fortunate, though generally having my patience sufficiently tried. . . . If, at any time of the year, a warm mist pervade the air, there is almost a certainty of success." At cool times of the year, the window is kept shut till the moths knock for admit- tance. Reading and writing may be combined with this plan of mothing. ** Moths are extremely sensible of any keenness in the air : a north or east wind is very likely to keep them from venturing abroad. Different species have different hours of flight. ... I have, for experiment's sake, sat up in the sum- mer till three o'clock, when the whole heaven was bright with the risincT sun, and moths of various kinds have never ceased arriving in succession till that time. Some of them must come from a considerable distance. Scotophila porphyrea, being a heath moth, must have come nearly a mile." Not only the Nocturna have come to Mr. Bird in the night, but " the Se- midiurna, the Geometridae, accompany them at all hours. Many coleopterous insects are also attracted . . . sometimes swarms of gnats . . . the house cricket once or twice. Redu- vius personatus has been amongst my captives, A few com- mon ichneumons and 7ipulae are frequent guests." What a world of interest these successive visiters must induce in a summer's night. Surely an entomologist must, while thus sitting and observing, have, like Shakspeare, a rich " Mid- summer Night's Dream " of his own ! Mr. Bird illustrates many of his remarks (and we have given but a sample of them) by adducing the names of the insects whose manners those remarks describe. His list follows, with those species distinguished " which he does not take by the lamp." — 4. Thoughts on the Geographical Distribution of Insects; by Delta. This is professed to be written with a trembling hand ; but the author seems to have fortified himself very strongly with an extensive and intimate acquaintance with the nature of his subject.

On the Head of Insects. We have, in VI. 435., given our humble opinion of this author's first letter on the osteology of insects. The present second letter, like the first, is of the highest possible value, and, therefore, interest, to every student in entomology ; and who in ento- mology is not a student?

Would we had volumes full of such notices on insects as that supplied on the dragon fly in p. 67. The end for which Mr. Newman labours is the establishment of a uniform nomenclature of the parts of insects ; for, until we can speak of the various parts of insects in common terms, a reciprocal communication of ideas between those who study insects (and every one who loves nature must) cannot take place. We wish his amiably intended, and, we believe, ex- cellently executed, labours all regard, and cordially commend them, and the nomenclature he has proposed for the parts of the head of insects, to the analytical examination of every entomologist. — Vll.

The history of the recent case, and the abstract of the previously recorded ones, occupy 40 pages. Pages 41. to 74. are occupied with a review of the " very different opinions which have at different times been entertained with respect to the origin of the proper entozoa of the human body," and with the author's own opinion on the subject.

The decisions of nature soon cut asunder the artificial arrangements of man. To acquire a true knowledge of the history of nations, we must study the physical structure of the soil, for this is the leading feature on which historical details are always dependent.

THE MAGAZINE OF NATURAL HISTORY. MARCH, 1834^. ORIGINAL COMMUNICATIONS. Art. I. On designating Genera and Subgenera, and on the Prin- ciples of Classijlcation which they involve. [VI. 385. 4-81.. 485., VII. 62. to 66.] By the Rev. Leonard Jenyns, A.M. F.L.S. Mr. Strickland seems (VII. 62.) to infer, from what I have written (VI. 385.) on the subject of classification, that my plan is " to distinguish subgenera by signs or letters." I beg to state that he has misunderstood me entirely. So far from adopting this plan, I am of opinion that in all cases sub- genera should be named. What I remarked (which, I pre- sume, led Mr. Strickland to this inference) was, that many modern genera had been established on characters too trivial and unimportant to entitle them even to the rank of sub- genera ; and I intimated that, where such had been adopted principally with a view to convenience, and because of the large number of species contained in the old groups of which they formed portions, it would have been better to have sub- stituted for them mere sectional divisions, indicated by signs. With respect to the much agitated question as to whether we are to employ the name of the genus or subgenus in de- signating any species we may wish to speak of, it appears to me it must be left in a great measure open for each individual to decide as he pleases. It would be difficult to lay down any rule, on such a subject, which would be generally adopted. For my own part, I should say, that, oi^ all ordinary occa- sions, it is quite sufficient to use the former only ; but where 1 was naming the species, with the particular view of point- ing out its affinities and its exact situation in the system, I should there employ both ; and I should write the name cf Vol. VII. — No. 38. h 9B On designating Genera and Subgenera. -the subgenus in a parenthesis. * Thus, I should usually say (speaking of the Lapland bunting), Emberiza lapponica ; but, in the particular instance just alluded to, Emberiza (Plectro- phanes) lapponica. I cannot forbear adding, on this occasion, that I fear I have been much misunderstood on the subject of the division of genera. The object of my former communication [VI. 385.3 was not so much to find fault with the subdividing of old genera, where there may appear just ground for the sub- division, or the calling of the new groups by this title, if we object to the adoption of that of subgenera, as with the not appreciating the relation which these new groups bear to the old one, and to the other genera in the same family with which this old one was considered of equal value. Perhaps, however, my meaning will be rendered more intelligible than it was in that article, by the assistance of a diagram. Let us, then, suppose the family of ^rdeidse, for instance, and three of its induded genera, to be represented in the following manner, — ^rdeidae A'rdea Ciconia Platalea; assuming that the above three groups, placed in the same line, are of equal value amongst themselves, but all subordi- nate to the one above, in which they are included, and which we here designate by the name of family. Suppose that, on farther investigation, we find that, in like manner as this family includes three genera f, so that one of these genera, say A'rden, includes also three subordinate groups. What do we do? We attach the same name, ^'rdea, though in a restricted sense, to that subordinate group which is more typical than the others ; while to the remaining two we affix, perhaps, the new names of Botaurus and iVycticorax ; and we carry on the diagram in this manner, — yirdeidae ^'rdea Ciconia Platalea ^'rdea Botaurus iVycticorax ; in which we still have the old group A'rdea held together by certain characters as before ; only we distinguish in it three * This is what Cuvier recommends, in his Histoire des Poissons, 4to edit, torn. ii. p. 41. note 1. In a former work he advises that, on ordinary occa- iions, the name of the subgenus be suppressed. {Reg.Aii., torn. i. p. xvii.) f I am not really asserting that there are no other existing genera in this family, but merely selecting these three as sufficient for my argument. 071 designating Genera and Subgenera, 99 minor groups, each of which has some additional characters peculiar to itself, of less importance than those common to all. Now, it is perfectly arbitrary in what point of view we choose to consider these three new groups ; we may either affix names to them or not ; we may call them genera, if we please, or subgenera, or mere sections of the old genus A^r^ dea : but what we must noi do (and here, I would observe, is the principal ground of my complaint) is, having determined them to be genera, first to abolish the original group ^^rdea, and then to place them on the same footing with Cic6nia and Platalea *, in this manner, — ^rdeidae A'rdea. Botauras iVycticorax Ciconia Platalea; or, raising ^'rdea to the rank of a family, and the group which w^e here call ^rdeidae to one of a still higher deno- mination, not to raise Ciconia and Platalea also ; for these three groups, ^Vdea, Ciconia, and Platalea, having been assumed to be of equal value, it is clear that, whatever rank we assign to one of them, we must assign the same to all. I am unwilling to extend this .communication, or I should make some comment on the objections which Mr. Newman has brought forward (VI. 485.) against the expressions which I adoptecl in my former article. [VI. 385.] I shall simply observe, that, when I talk of principles of classification, I do not mean principles of my own setting up, as that gentleman seems to think, but such as have been laid down by those who have studied most deeply the philosophy of the science, and such as are generally acknowledged by all professed naturalists. Of this nature is the only principle to which I had occasion to allude ; viz., thai all groups bearing the same title shoidd be groups of the same value. I conceive that every systematist would assent to this prin- ciple, at the same time that no one would ever think of assert- ing that it was now, for the first time, brought forward and offered to his notice.

Last year I partly promised [V. 241.] that, on some dis- mal winter's evening, I would sit me down, and write the history of the rook, llie period has now arrived. Nothing can be more gloomy and tempestuous than the present aspect of the heavens. The wind is roaring through the naked branches of the sycamores, the rain beats fiercely on the eastern windows, and the dashing of the waves against the walls of the island warns us that one of November's dark and stormy nights is close at hand ; such a night, probably, as that in which Tam O'Shanter unfortunately peeped into Kirk Allowa}^ Foreigners tell us that on these nights Englishmen are prone to use the knife, or a piece of twisted hemp, to calm their agitated spirits. For my own part, I must say that I have an insuperable repugnance to such anodynes ; and, were a host of blue devils, conjured up by November's fogs, just now to assail me, I would prefer combating the phantoms with the weapons of ornithology, rather than run any risk of disturbing the economy of my jugular vein, by a process productive of very unpleasant sensations, before it lulls one to rest. According to my promise, I will now pen down a few re- marks on the habits of the rook, which bird, in good old sensible times, was styled frugilegus. It is now pronounced to he prcjedatonus. Who knows but that our great ones in ornithology may ultimately determine to call it up to the house of hawks ? If this useful bird were not so closely allied to the carrion crow in colour and in shape, we should see it sent up to the tables of the rich, as often as we see the pigeon. But pre- judice forbids the appearance of broiled rook in the lordly mansion. If we wish to partake of it, we must repair to the cottage of the lowly swain, or, here and there, to the hall of the homely country squire, whose kitchen has never been blessed by the presence of a first-rate cook, and whose yearn- ings for a good and wholesome dish are not stifled by the fear of what a too highly polished world will say. There is no wild bird in England so completely gregarious as the rook; or so regular in its daily movements.' The ring- doves will assemble in countless nmltitudes, the finches will unite in vast assemblies, and waterfowl will flock in thousands to the protected lake, during the dreary months of winter: but, when the returning sun spreads joy and consolation over the face of nature, their congregated numbers are dissolved, Observations on the Habits of the Rook, 101 and the individuals retire in pairs to propagate their respective species. The rook, however, remains in society the year throughout. In flocks it builds its nest, in flocks it seeks for food, and in flocks it retires to roost. About two miles to the eastward of this place are the woods of Nostell Priory, where, from time immemorial, the rooks have retired to pass the night. I suspect, by the ob- servations which I have been able to make on the morning and evening transit of these birds, that there is not another roosting-place for, at least, thirty miles to the westward of Nostell Priory. Every morning, from within a few days of the autumnal to about a week before the vernal equinox, the rooks, in congregated thousands upon thousands, fly over this valley in a westerly direction, and return in undiminished numbers to the east an hour or so before the night sets in. In their morning passage, some stop here ; others, in other favourite places farther and farther on ; now repairing to the trees for pastime, now resorting to the fields for food, till the declining sun warns those which have gone farthest to the westward that it is time they should return. They rise in a mass, receiving additions to their numbers from every inter- vening place, till they reach this neighbourhood in an amazing flock. Sometimes they pass on without stopping, and are joined by those which have spent the day here. At other times they make my park their place of rendezvous, and cover the ground in vast profusion, or perch upon the surrounding trees. _After tarrying here for a certain time^ every rook takes wing. They linger in the air for a while, in slow revolving circles, and then they all proceed to Nostell Priory, which is their last resting-place for the night. In their morn- ing and evening passage, the loftiness or lowliness of their flight seems to be regulated by the state of the weather. When it blows a hard gale of wind, they descend the valley with astonishing rapidity, and just skim over the tops of the irlervening hills, a few feet above the trees : but, when the sky is calm and clear, they pass through the heavens at a great height, in regular and easy flight. Sometimes these birds perform an evolution, which is, in this part of the country, usually called the shooting of the rooks. [V. 239.] Farmers tell you that this shooting por- tends a coming wind. He who pays attention to the flight of birds has, no doubt, often observed this downward movement. When rooks have risen to an immense 'height in the air, so that, in appearance, they are scarcely larger than the lark, they suddenly descend to the ground, or to the tops of trees exactly under them. To effect this, they come headlong H 3 102 Observations on the Habits of the RooJc, down, on pinion a little raised, but not expanded, in a zig-zag direction (presenting, alternately, their back and breast to you), through the resisting air, which causes a noise similar to that of a rushing wind. This is a magnificent and beau- tiful sight to the eye of an ornithologist. It is idle to suppose for a moment that it portends wind. It is merely the ordi- nary descent of the birds to an inviting spot beneath them, where, in general, some of their associates are already assem- bled, or where there is food to be procured. When we consider the prodigious height of the rooks at the time they begin to descend, we conclude that they cannot effect their arrival at a spot perpendicular under them, by any other process so short and rapid. Rooks remain with us the year throughout. If there were a deficiency of food, this would not be the case ; for, when birds can no longer support themselves in the place which they have chosen for their residence, they leave it, and go in quest of nutriment elsewhere. Thus, for want of food, my- riads of wildfowl leave the frozen north, and repair to milder climates ; and in this immediate district, when there is but a scanty sprinkling of seeds on the whitethorn bush, our flocks of fieldfares and of redwings bear no proportion to those in times of a plentiful supply of their favourite food. But the number of rooks never visibly diminishes ; and on this account we may safely conclude that, one way or other, they always find a sufficiency of food. Now, if we bring, as a charge against them, their feeding upon the industry of man, as, for example, during the time of a hard frost, or at seedtime, or at harvest, at which periods they will commit depredations, if not narrowly watched, we ought, in justice, to put down in their favour the rest of the year, when they feed entirely upon insects. Should we wish to know the amount of noxious insects destroyed by rooks, we have only to refer to a most valuable and interesting paper on the services of the rook, signed T. G. Clitheroe, Lancashire, which is given in Vol. VI. p. 14'2. of this Magazine. I wish every farmer in England would read it. They would then be convinced bow much the rook befriends them. Some author (I think. Goldsmith) informs us that the North American colonists got the notion into their heads that the purple grakle was a great consumer of their maize [1. 47.]; and these wise men of the west actually offered a reward of threepence for the killed dozen of the plunderers. This tempting boon soon caused the country to be thinned of grakles, and then myriads of insects appeared, to put the good people in mind of the former plagues of Egypt. They Observations on the Habits of the Rook. lol damaged the grass to such a fearful extent, that, in 1749, the rash colonists were obliged to procure hay from Pennsylvania, and even from England. Buffon mentions that grakles were brought from India to Bourbon, in order to exterminate the grasshoppers. The colonists, seeing these birds busy in the new-sown fields, fancied that they were searching for grain, and instantly gave the alarm. The poor grakles were pro- scribed by government, and in two hours after the sentence was passed, not a grakle remained in the island. The grass- hoppers again got the ascendency, and then the deluded islanders began to mourn for the loss of their grakles. The governor procured four of these birds from India, about eight years after their proscription, and the state took charge of their preservation. Laws' were immediately framed for their protection ; and, lest the people should have a hankering for grakle pie, the physicians were instructed to proclaim the flesh of the grakle very unwholesome food. Whenever I see a flock of rooks at work in a turnip field, which, in dry wea- ther, is often the case, I know that they have not assembled there to eat either the turnips or the tops, but that they are employed in picking out a grub, which has already made a lodgement in the turnip. Last spring, I paid a visit, once a day, to a carrion crow's nest on the top of a fir tree. In the course of the morn- ing in which she had laid her fifth egg, I took all the eggs out of the nest, and in their place I put two rooks* eggs, which were within six days of being hatched. The carrion crow attended on the stranger eggs, just as though they had been her own, and she raised the young of them with parental care. When they had become sufficiently large, I took them out of the nest, and carried them home. One of them was sent up to the gamekeeper's house, with proper instructions ; the other remained with me. Just at this time an old woman had made me a present of a barn-door hen, " Take it, Sir," said she, " and welcome ; for, if it stays here any longer, we shall be obliged to kill it. When we get up to wash in the morning, it crows like a cock. All its feathers are getting like those of a cock ; it is high time that it was put out of the way, for when hens turn cocks people say that they are known to be very unlucky ; and, if this thing is allowed to live, we don't know what may happen. It has great spurs on its legs, and last summer it laid four eggs. If I had had my own way, it would have- been killed when it first began to crow." I received the hen with abundant thanks ; and, in return, I sent the old woman a full-bred Malay fowl. On examining the hen, I found her comb very H 4 104? Observations on the Habits of the Rook. large ; the feathers on the neck and rump much elongated ; the spurs curved, and about l^in. long; the two largest feathers in her tail arched, and four or five smaller arched ones, of a beautiful and glossy colour, hanging down on each side of the tail. In a word, this hen had so masculine an appearance, that, when strangers looked at her, they all took her to be a cock, and it was with difficulty I persuaded them that she was a hen. We allowed her the range of a sheltered grass-plot, flanked on one side by holly trees, and open to the lake on the other. Here, also, was placed in a cage the young rook which I had taken from the nest of the carrion crow. The hen showed such an antipathy to it, that, when- ever I held it to her, she would immediately fly at it. When visiters came to inspect her, I had only to take the rook out of the cage, and pit it against her, when she would stand upright, raise the long feathers on her neck, and begin to cackle, cluck, and crow. One morning the rook had managed to push aside a bar in front of its cage. A servant, in passing by, looked into it, and missed the bird. The hen had also disappeared. On search being made, they were both found floating side by side, dead, in the lake below. We conjectured that the hen had pursued the rook after its escape from the cage, and that the wind, which blew very strong that morning, liad forced them both into a watery grave. I had still one rook left at the gamekeeper's. It was kept in a cage, which was placed on a little stand in his garden ; and I had given orders that upon no account was it to be allowed to go at large. The feathers remained firm at the base of the bill till the 15th of August; on which day the keeper perceived that a few feathers had dropped from the lower mandible, and were lying at the bottom of the cage. In a couple of weeks more, the lower mandible had begun to put on a white scurfy appearance, while here and there a few feathers had fallen from the upper one. This is the purport of the keeper's in- formation to me, on my return home from Bavaria. On the 31st of the same month, a terrible storm set in. By what the keeper told me, the night must have been as dark and dismal as that in which poor King Lear stood in lamentation, and exposed his hoary locks to the four rude winds of heaven. A standard white-heart cherry tree, }ierhaps the finest in Yorkshire, and which, for many generations, had been the pride and ornament of this place, lost two large branches during the gale ; and in the morning, when the keeper rose, he found the cage shattered and upset, and driven to the far- thest corner of his garden. The rook was quite dead. It had lost its life, either through the inclemency of that stormy Observations on the Habits of the Rook, 105 night, or through bruises received in the fall of the cage. Thus both the rooks were unlucky. The old woman, no doubt, could clearly trace their misfortunes to her crowing hen. However, the experiment with the two young rooks, though not perfect, has nevertheless been of some use. It has shown us that the carrion crow makes no distinction betwixt its own eggs and those of the rook ; that it can know nothing of the actual time required to sit upon eggs in order to produce the young ; that the young of the rook will thrive under the care of the carrion crow, just as well as under that of its own parents ; and finally, that the feathers fall off from the root of the rook's bill, by the order of nature, as was sur- mised by the intelligent Bewick, and not by the process of the bird's thrusting its bill into the earth, in search of food, as is the opinion of some naturalists. [III. 402., V. 241.] The rook advances through the heavens with a very re- gular and a somewhat tardy beat of wing; but it is capable of proceeding with great velocity when it chooses : witness its pursuit and attack on the sparrowhawk and kestrel. It is apt to injure, in the course ot' time, the elm trees on which it builds its nest, by nipping off the uppermost twigs. But this, after all, is mere conjecture. The damage may be caust^d by an accumulation of nests, or by the constant resort of such a number of birds to one tree. Certain, however, it is, that, when rooks have taken possession of an elm tree for the pur- pose of incubation, the uppermost branches of that tree are often subject to premature decay. Though the flocks of rooks appear to have no objection to keep company, from time to time, with the carrion crows, in a winter's evening, before they retire to roost, still I can never see a carrion crow build its nest in a rookery. There was always a carrion crow's nest here, in a clump of high Scotch pines, near the stables, till the rooks got possession of the trees ; the carrion couple then forsook the place : the rooks were dislodged from this clump of trees ; and then a pair of carrion crows (the same, for aught I know to the contrary) came and built their nest in it. The rook lays from three to five eggs, varying much, like those of the carrion crow, in colour, shape, and size. After the rooks have built, and even lined their nests, they leave them on the approach of night, to repair to the general ren- dezvous at Nostell Priory ; but, as soon as they begin to lay, they then no longer quit the trees' at night, until they have reared their young. When this has been effected, we see large flocks of them resorting to the different woods of the neighbourhood to pass the night. This they continue to do, till a few days before the autumnal equinox, when, for reasons 106 Natural History of Molluscom Animals : — which baffle all conjecture, they begin to pass over this valley every morning in a westerly direction, and return in the even- ing to their eastern roosting-place in the woods of Nostell Priory. Rooks are observed to keep up a very close and friendly intercourse with starhngs [VII. 183.] and jackdaws [VI. 394. 516.] ; but, on looking at them in the fields, the observer will perceive, that, while the jackdaws mix promiscuously with the rooks, both in their flight and in searching for food, the star- lings always keep in their own flock. This circumstance has long engaged my attention ; but I am no farther advanced in the investigation than I was on the first day on which I set out. It is one of the many secrets in the habits of birds, which will, perhaps, be for ever concealed from our view. Walton Hall, Nov. 27. 1833. Charles Waterton.

Letter 12. On their Respiration. The respiration of the Mollusca is so slow, so little ob- vious, and so easily suspended for a time, that it is possible you may never have observed the process even in those species which daily cross your path. You will, therefore, in your next walk, please to examine the snail or the slug while they are in progression, and you will see them at intervals open wide a circular hole on the side of the neck and near the margin of the shield or collar, and, after dilating it to the utmost, they will close it again until its place becomes im- perceptible ; this they do about four times in a minute, ex- pelling at each time the effete air, and inhaling a fresh supply. In like manner, the aquatic tribes, while crawling along the surface, raise from time to time the pulmonary aperture, in order to emit the vitiated air, sometimes even with a crackling noise, and to receive an equal quantity their Respiration. 107 unadulterated before the aperture is shut. This process is not so obvious in the branchial Mollusca, and in many of them, from the position of the gills, such a function is not necessary to renew the water around them. Where, how- ever, the gills are strictly internal, it seems probable that the water is regularly changed when the creatures are in their natural habitats and undisturbed : we know that such is the case with the Cephalopoda, in which inspiration and ex- spiration are well marked. " The first is effected by a gradual dilatation of the sac in every direction, but particularly at the sides, accompanied by a subsidence of the lateral valves, col- lapse of the walls of the funnel, and a rush of water through the lateral openings into the sac. Inspiration being com- pleted, the lateral valves are closed, the sac is gradually contracted, the funnel erected and dilated, and the water ex- pelled through it with great force, and in a continued stream." Dr. Coldstream, from whose letter I quote the preceding sentence, has seen the stream emitted by an individual of the Octopus ventricosus, " whose sac measured about four inches in length, carry light bodies to the distance of eleven inches from the orifice of the funnel. Respiration is performed more frequently in young than in adult individuals. One, whose sac measured 1^ in. in length, I saw respire 18 times per minute ; and the larger one, mentioned above, respired 10 times per minute. The time seemed to be pretty equally divided between inspiration and exspiration." In the bi- valves, whose cloak forms a shut sac, the water is sucked in through the siphonal tube, when the capacity of the sac is increased by its own expansion, or by the opening of the shells ; and by its muscular contraction, aided sometimes by the closure of the shells, it is again expelled in a stream from the anal siphon : but there is no regularity in the process in such species as I have observed in confinement. It is the same with the Mollusca tunicata. The branchial sac is muscular, and just as its capacity is enlarged, apparently by the contraction of its longitudinal fibres, the water flows in to fill the space in a slow and uniform current, through the branchial aperture only, for none can be detected entering by the anal orifice. It is, after a space, expelled again by a con- traction of the annular fibres of the sac, but the voluntary contractions for this purpose, as stated above, take place at irregular intervals of time, and, for the most part, not oftener than once in a minute. {Cu\\e\\Molliis. Me7n. xx. p. 17.; Coldstream, in Edin. New Phil. Joiirn. for July, 1830, p. 240.) I have told you that the respiration of the Mollusca is at all times slow, and easily suspended for a long })eriod ; but, to obviate the inconveniences which might result from this, and 1 0^ Natural History of Molluscous Animals ; — to supply the place of that regularly alternate and ceaseless play of the resph-atory muscles of the vertebrates, Dr. Sharpey has discovered that, in " the Mollusca, and other inferior tribes of aquatic animals, the external covering of the body generally, but especially of the respiratory organs, possesses the power of impelhng the water contiguous to it in a determinate direction along the surface, by which means a constant current is kept up, and the blood exposed to the influence of successive portions of the surrounding element : this peculiar provision effecting, in those creatures, the same purpose as the respiratory muscles in the more perfect animals." These currents, in the Mollusca at least, and probably in all the animals in which they have been detected, are produced by the action of minute cilia, visible only with a glass, which are in constant motion, and clothe all the surfaces along which the currents are excited. Similar cilia had been observed on the eggs and organs of many zoophytes by previous naturalists, and in a few naked Mollusca, by Dr. Fleming; but the merit of proving their existence in all the great families of the Mollusca, with the exception of the Cephalopoda and the Tunicata, and of pointing out their use, is due to Dr. Sharpey. Carus came near the discovery ; for he observed the currents in question, but left uninvestigated their cause ; or, rather, he attributed the phenomena to one which has probably little efficiency. His words are : — " In a living bivalve, it is easy to observe that the water gains access to the branchial laminae by the fissure in the cloak, and escapes by the anal tube, which serves also to evacuate excrement and ova. It has not, however, been hitherto noticed, that this current is uninterrupted, and that thus these animals, when not too deeply immersed, form an eddy on the surface of the water. But as, in almost all other animals, the influx of air or water to the respiratory organs is intermittent, the simultaneous and continuous current into the fissure of the cloak and out of its tube, of which I have satisfied myself by numerous observations, must depend on a very peculiar mechanism, which consists chiefly in the mus- cularity of the cloak, but partly also in the mobility of the gills themselves, and may be compared to the mechanism of certain bellows, which produce an uninterrupted current of air by means of double bags." [Camp. Anat., transl. vol. ii. p. 148.) As this discovery appears to me the most important which has been made of late years in the physiology of these animals, you will permit me to transcribe, for your perusal, a paragraph of considerable length from Dr. Sharpey's Essay, with a view of giving some farther illustration of the process. their Respiration. 109 " When a live muscle (Mytilus edulis) is attentively examined in a vessel of sea water, it is soon observed to open its shell in a slight degree, and about the same time a commotion may be perceived in the water in its vicinity. This is occa- sioned by the water entering at the posterior or large ex- tremity of the animal, into the cavity in which the gills are lodged, and coming out, near the same place, by a separate orifice, in a continued stream. This current is obviously intended for the purpose of renewing the water required for the respiration and nutrition of the animal ; but, though it is now a well-established fact in the history of the muscle, the mechanism by which it is produced has not, so far as I know, been satisfactorily explained. Some have contented them- selves with ascribing it to an alternate opening and shutting of the shell ; but, as no such motion takes place in the shell, except at distant and irregular intervals, it is evident that the constant passage of the water cannot be explained in this way. Others, who saw the insufficiency of this explanation, have endeavoured to account for it by assuming peculiar contractions and dilatations of the mantle in virtue of its muscular power, or, like M. de Blainville, have supposed that the triangular labial appendages placed round the mouth excited the current by their constant motion. After meeting with the currents in the tadpole, it struck me that the entrance and exit of the water in the bivalve Mollusca might not improbably be owing to a similar cause ; and that the surface of the respiratory organs, and other parts over which the water passed, might have the power of exciting currents in it, the combined effect of which would give rise to the entering and returning stream. '' This conjecture proved, on actual examination, to be right. Having cut off a portion of the gill, I found that a current was excited along its surface in a determinate di- rection, and that it moved itself through the water in an opposite one, exactly as in the case of the tadpole. The whole surface of the gills and labial appendages or accessory gills, the inner surface of the cloak, and some other parts, produced this effect. The currents on the gills are of two kinds. When finely powdered charcoal is put on any part of their surface, a great portion of it soon disappears, having penetrated through the interstices of the vessels into the space between the two layers of the gill. On arriving here, a part is forced out again at the base of the gill from under the border of the unattached layer, but most of it is con- veyed rapidly backwards in the interior of the gill between the two layers, and almost immediately escapes at the ex- IrlO' Natural History of Molluscous Animals : — cretory orifice, or that from which the general current already mentioned is observed to come out. That portion of the powder which remains outside the gill is carried along its surface in straight lines from the base to the margin, along which it then advances onwards towards the fore part of the animal. As the spaces between the layers of all the gills terminate directly or indirectly at the excretory orifice, it is easily conceivable that the water, penetrating by the entire surface of these organs, may, by their concentrated effect, give rise to the powerful current which is observed to come out from the animal. " On examining a portion of the gills with a powerful lens, I perceived that it was beset with minute cilia, which are evidently instrumental in producing the different currents. Most of them are ranged along the anterior and posterior margin of each of the vessels composing the gills, in two sets : one nearer the surface, consisting of longer and more opaque cilia; the other close to the first, but a little deeper, in which they are shorter and nearly transparent. Both sets are in constant motion, but of this it is difficult to convey a correct idea by description. The more opaque cilia, or those of the exterior range, appear and disappear by turns, as if they either were alternately pushed out and retracted, or were continually changing from a horizontal to a vertical direction. The motion of the other set appears to consist in a succession of undulations, which proceed in a uniform manner along the margin of the vessel from one end to the other. It resembles a good deal the apparent progression of the turns of a spiral when it revolves on its axis, and might very easily be mistaken for the circulation of a fluid in the interior of a canal, more particularly as the course of the undulations is different on the two edges of the vessel, being directed on the one towards the margin of the gill, and on the other towards the base. But, besides that the undu- lations continue to go on for some time in small pieces cut off from the gill, which is inconsistent with the progression of a fluid in a canal, the cilia are easily distinguished when the undulatory motion has become languid- When it has entirely stopped, they remain in contact with each other, so as to present the appearance of a membrane attached to the edge of the vessel. " It is very remarkable, that, when the gill is immersed in fresh water, both the currents and the motion of the cilia are almost instantaneously stopped." * * On a peculiar Motion excited in Fluids by the Surfaces of certain Animals ; by William Sharpey, M.D. Edin. Med. and Surg. Journaly vol. xxxiv. p. 118, &c. their Respiration, 111 The purpose of the respiratory organs, and of the currents just described, is, to expose the blood freely to the purificative action of the atmospherical air, that it may be purged of some noxious qualities which it has acquired during its circulation through the venous system, and fitted again for the continuance of the life of the individual. In the ver- tebrate animals the blood is altered, even in its outward ap- pearance, by this process ; from a dark it becomes a bright red fluid: but no perceptible change is operated on the white serous blood of the Mollusca, yet that it has experienced a similar purification is not to be doubted ; for the air breathed by these creatures is similarly deteriorated, as it would have been had it been breathed by the quadruped or bird ; the oxygen has disappeared, and its place become occupied by an equal bulk of carbonic acid gas. This had been proved by the well known experiments of Spallanzani and other physiologists ; and though, in general, the proportion holds good, yet it appears, from the recent experiments of Tre- viranus, that the absorption of oxygen is not always pro- portional to the excretion of carbonic acid, the proportion of the one to the other depending on the strength of the respiration, the time of its continuance while the respir- ability of the air is diminishing, and the volume of the air in which the respiration is performed. " The more car- bonic acid," says Treviranus, " there is developed while breathing in the open air, and the less the power of con- tinuing in a medium deficient in oxygen, the less is the proportion of the consumption of oxygen to the production of carbonic acid gas, whence a small quantity of atmospheric air is respired for a moderate period. But when the re- spiration is continued for a longer period in the same air^ and the strength of the individual begins to sink, the excre- tion of the latter diminishes more rapidly than the absorption of the former. We know that the higher classes of animals, when enclosed in a certain quantity of air, die long before all its oxygen has been exhausted. The case is very different with many of the Mollusca under the same circumstances; for they not only consume all the oxygen, but actually con- tinue afterwards to exspire carbonic acid gas : consequently, after the respiration has been continued for some time, there has been more of the latter excreted than there has been con- sumed of the former; nay, sometimes this occurs even before all the oxygen has been consumed." [Edin. New Phil. Jouni., April, 1833, p. 383.*) These observations may serve to * The Rev. Mr. Guilding has conjectured that some Mollusca may even purify water: — " AMeritinae are destroyed with great difficulty : some. 112 Natural History of Molluscous Animals : — explain, in some degree, the apparent apathy of the Mollusca generally to a temporary deprivation of their respiratory media : for snails may be immersed in water for many hours without injury; and the purely aquatic species will survive as long a time exposed to the atmosphere. Oysters and muscles, as every one knows, and probably all the Conchifera, will live for three or four days without any more water to breathe in than what may lie in the concavity of their shells ; and Mr. Boyle has some experiments which illustrate, in a remark- able manner, their tenacity of life even in vacuum. He found that two oysters, put " into a very small receiver," exhausted of air, were alive at the end of twenty-four hours ; " but how long afterwards they continued so, I did not observe." {Phil. Trans., 1670, p. 2023.) Another oyster was put into a vial full of water before being enclosed in the receiver, " that, through the liquor, the motion of the (air) bubbles, expected from the fish, might be more pleasantly seen and considered. This oyster proved so strong, as to keep itself close shut, and repressed the eruption of the bubbles, that in the other did force open the shells from time to time ; and kept in its own air as long as we had occasion to continue the trials." {Ibid., p. 2024.) Shelled snails (Helices) appeared to be not more disordered in vacuity ; and even the slugs (Z>imax) endured the privation for many hours. The same illustrious philo- sopher included two of the latter " in a small portable receiver," carefully exhausted ; " but, though they did not lose their motion near so soon as other animals were in our vacuum wont to do, yet, coming to look on them after some hours, they appeared moveless and very tumid; and, at the end of twelve hours, the inward parts of their bodies seemed to be almost vanished, and they seemed to be but a couple of small full-blown bladders ; and, on the letting in of the air, they immediately so shrunk, as if the bladders had been pricked : the receding air had left behind it nothing but skins ; nor did either of the snails afterwards, though kept many hours, give any signs of life." {Ibid., p. 2050.) In this experiment, it is obvious that the snails were killed from the mechanical effects of the expansion of the air within them, and not from its ingress to the pulmonary cavity being prevented. which were even kept close in salt water, seemed to have the power of purifying it, and rendering it fit for respiration; while many large air- bubbles were generated in the glass. Some power of this kind would be very valuable to those species which inhabit maritime ponds, the waters of which, nearly dried up at certain seasons, must be stagnant and unwhole- some." (Zoological Journal^ vol. v. p. 33.) their Respiration, 113 But there are on record some extraordinary facts, which seem to prove that, under certain conditions, all of which are not yet known, the respiration of many Mollusca, more espe- cially the terrestrial, may be suspended for an indefinite period, and again renewed by the application of heat and moisture ; life, as it were, keeping watch, and holding at bay every destructive agent, but without giving any outward sign of her presence and constant wakefulness, until the return of those influences in which she joys. " All the land Testacea," to use the words of Dr. Fleming, " appear to have the power of becoming torpid at pleasure, and independent of any alter- ations of temperature. Thus, even in midsummer, if we place in a box specimens of the Helix hortensis, nemoralis, or arbustorum, without food, in a day or two they form for themselves a thin operculum, attach themselves to the side of the box, and remain in this dormant state. They may be kept in this condition for several years. No ordinary change of temperature produces any effect upon them, but they speedily revive if plunged in water. Even in their natural haunts, they are often found in this state during the summer season, when there is a continued drought. With the first shower, however, they recover, and move about ; and at this time the conchologist ought to be on the alert." {Phil, Zool.^ vol. ii. p. 77.) I may illustrate these remarks, which are per- fectly correct, by some additional examples; one or two of which you may find to require an exercise of faith for which you may not be altogether prepared. Mr. Lyell tells us that " four individuals of a large species of B^limus, from Val- paraiso, were brought to England by Lieutenant Graves, who accompanied Captain King in his late expedition to the Straits of Magellan. They had been packed up in a box, and en- veloped in cotton, two for a space of thirteen, one for seven- teen, and a fourth for upwards of twenty months ; but, on being exposed, by Mr. Broderip, to the warmth of a fire in London, and provided with tepid water and leaves, they re- vived, and are now living in Mr. Loddiges's palm-house.'* {Princ. GeoL, vol. ii. p. 109.) Dr. Elliotson put a garden snail " into a dry closet, without food, a year and a half ago : it became torpid, and has remained so ever since, except when- ever I have chosen to moisten it. A few drops of water revive it at any time." (Blumenbach's Phi/siologz/, p. 182.) Similar instances may be found in some of the periodical journals ; but they are as nothing when compared with the snails of Mr. Stuckey Simon, a merchant of Dublin, which, on being immersed in water, recovered and crept about after an uninter- VoL.

Whether what follows is so, I leave to your own decision ; but I will not say you are unreasonably sceptical if you deem it too tramontane. " Professor Eaton of New York stated," says my authority, " that the diluvial deposits through which the Erie Canal was made contained ridges of hard compact gravel. On cutting through one of these, near Rome village, * " Mr. Stuckey Simon, a merchant of Dublin, whose father, a fellow of the Royal Society, and a lover of natural history, left to him a small collection of fossils and other curiosities, had among them the shells of some snails. About fifteen years after his father's death (in whose pos- session they continued many years), he by chance gave to his son, a child about ten years old, some of these snail shells to play with. The boy put them into a flower-pot, which he filled with water, and the next day into a basin. Having occasion to use this, Mr. Simon observed that the animals had come out of their shells. He examined the child, who assured him that they were the same he had given him, and said he had also a few more, which he brought. Mr. Simon put one of these into water, and in an hour and a half after observed that it had put out its horns and body, which it moved but slowly, probably from weakness. Major Vallancey and Dr. Span were afterwards present, and saw one of the snails crawl out, the others being dead, most probably from their having remained some days in the water. Dr. Quin and Dr. Rutty also examined the living snail several different times, and were greatly pleased to see him come out of his solitary habitation after so many years' confinement. Dr. Macbride, and a party of gentlemen at his house, were also witnesses of this surprising phe- nomenon. Dr. Macbride has thus mentioned the circumstance : — ' After the shell had lain about ten minutes in a glass of water that had the cold barely taken off, the snail began to appear, and in five minutes more we perceived half the body pushed out from the cavity of the shell. We then removed it into a basin, that the snail might have more scope than it had in the glass ; and here, in a very short time, we saw it get above the sur- face of the water, and crawl up towards the edge of the basin. While it was thus moving about, with its horns erect, a fly chanced to be hovering near, and, perceiving the snail, darted down upon it. The little animal instantly withdrew itself into the shell, but as quickly came forth again when it found the enemy was gone off'. We allowed it to wander about the basin for upwards of an hour, when we returned it into a wide-mouthed phial, wherein Mr. Simon had lately been used to keep it. He was so obliging as to present me with this remarkable shell ; and I observed, at twelve o'clock, as I was going to bed, that the snail was still in motion j but next morning I found it in a torpid state, sticking to the side of the glass.' " A few weeks afterwards the shell was sent to Sir John Pringle, who showed it at a meeting of the Royal Society ; but some of the members imagining that Mr. Simon must have been imposed upon by his son having substituted fresh shells for those that had been given to him, the boy was reexamined by Dr. Macbride on the subject, who declared that he could find no reason to believe that the child either did or could impose upon his father. Mr. Simon's living in the heart of the city rendered it almost impossible for the boy (if he had been so disposed) to collect fresh shells, being at that time confined to the house with a cold. Mr. Simon has also declared that he is positive those were the shells he gave to him, having in his cabinet many more of the same sort, and nearly of the same size." (Bingley's Animal Biogra'phy^ vol. iii. p. 574.) their Respiration. 115 16 miles west of Utica, the workmen found several hundred of live molluscous animals. They were chiefly of the Mya. cariosa and Mya purpi^rea. The workmen took the animals, fried, and ate them. He adds, ' I was assured that they were taken alive ^2ft. deep in the deposit. Several of the shells are now before me. The deposit is diluvial. These animals must have been there from the time of the deluge, for the earth in which they were is too compact for them to have been produced by a succession of generations. These freshwater clams of 3000 years old precisely resemble the same species which now inhabit the fresh waters of that district ; therefore, the lives of these animals have been greatly prolonged by their exclusion from air and light for more than 3000 years." (Silliman's Amer. Journal^ No. xv. p. 249., as quoted in Tur- ner's Sacred History, p. 473.) With the exception of the last example, the others refer to land Testacea ; but some pulmoniferous aquatic species are equally capable of assuming this state of torpidity, when under circumstances which deprive them of their respiratory medium. In early spring, I have more than once observed the Limneus fossarius to abound in small pools of water, which were dried up as the season advanced ; and when, after a careful search, the little snails were found, in a torpid condition, concealed in the cracks made by the drought, or under small clods of earth, where they awaited a happier season to refill their pools, and permit them to resume the functions of active life. Per- haps, in this country, their torpidity can rarely be continued beyond a few weeks ; but, in tropical climes, similar species can pass the dry season of five long months in this state. Thus, Adanson informs us that the minute freshwater shell, which he calls Bulimus, is to be seen only from the month of September to January, in the marshes of Senegal, formed by the rains which fall in June, July, August, and September. When these marshes are dried up, and, as it were, roasted by the sun, the shellfish disappear; a few empty shells alone being left, to show where they had been ; but they never fail to return with the rainy season ; and Adanson remarked that, the hotter the preceding summer, the more abundant was the issue of the succeeding hordes. How, asks the author, shall we explain this marvellous reproduction ? Can the eggs of the animal, necessarily very delicate and minute; can they remain in a soil so burned up, without being entirely dried; or can the animals themselves, if it is true that they conceal themselves in the bosom of the earth, can they resist, during five or six months, the heat of a burning sun ? {Hist. Nat. i. 2 i 1 6 Natural History of Molluscous Animals : — du Senegal, p. 7.) The latter supposition is the only one which can, I think, solve the question. When in this torpid state, the condition of the snail itself has not been ascertained. Some authors speak of it as being dormant^ and the language would seem to imply that they consider it in a state of sleep, in which the circulation and re- spiration go on uninterruptedly and as strongly as when awake ; but I suspect that the authors alluded to never intended that such an inference should be drawn from their analogical lan- guage. The fact is, it is not known precisely whether the circulation goes on or is stopped, or whether the contact of air is essential or otherwise. It is difficult to believe that all the functions as well as the signs of life cease entirely ; and yet it is scarcely less so to suppose that, for the space of fifteen years or more, those functions could exist without some supply of food to keep up the waste and secretions, however trivial, which necessarily flow from a circulation, or without some air to purify the circulating fluid.* If I deem it necessary to distinguish torpidity from sleep, it is, perhaps, not less so to distinguish it from the state of hybernation, although the phenomena of both are more strictly analogous. Snails become torpid when the atmosphere is hot and dry ; and, as often as they are unbound by the application of a warm moisture, they come forth from the shell strong and vigorous ; but, -^ intelligent of seasons," they begin instinctively to seek hybernating quarters at a moist season of the year, and before the cold has benumbed their powers ; and, if roused ultimately, their languid move- ments evidence their weakness, and bespeak our sympathy to leave them to repose. Whether the vital functions in these creatures are similarly aff*ected during torpor and hybernation remains to be determined. It is probable that they are. In this country, and in others with similar climates, pro- bably all the terrestrial shelled snails, and all the pulmoniferous freshwater MoUusca, pass the winter in a state of hybernation. I believe that the naked slugs do not hybernate ; for, although they retire under stones, clods of earth, or moss, to protect * " This living principle has the singular property of remaining dormant and inert for years or ages ; without, therefore, ceasing to exist. We all know that seeds may be kept a long while unsown, and yet grow whenever planted in a suitable soil . This, again, is like animals which have been found enclosed in trees, and yet have revived. When plants are buried in the ground to a greater depth than is natural to them for their proper growth, they do not vegetate; but they do not therefore die; they retain their power of vegetation to an unlimited period; and when, by any acci- dent, brought so near the surface as to suit their evolution, they begin immediately to grow." (Turner's Sacred History^ p. 195.) their Respiration, 117 themselves from the cold and storms of the season, yet I have always found them immediately to resume their activity when taken from their concealments, and they are in motion all the winter in mild weather. It is not certainly known, although the contrary has been asserted *, that any marine Molluscum hybernates. There would seem to be no necessity that the snails of tropical countries should be endowed with this remarkable property ; but the observations of Adanson prove the contrary. He tells us that the BMimus Kdmbeul appa- rently passes the nxiinter^ or dry season, in a deep slumber, like the snails ofT^urope ; for he found several of them which were half-buried, in the month of September, at the roots of trees and in the thickest brushwoods ; and of these some had already closed the aperture of their shell very exactly with a lid of a whitish and plaster-like matter, to protect themselves against the long droughts which continue for eight or nine months uninterruptedly. [Hist. Nat. dn Senegal, p. 18.) None of the hybernating Mollusca exhibit any remarkable cunning in the selection of their hybernacula or winter quar- ters. On the approach of the cold weather, the terrestrial tribes seek out a convenient station in crevices of old walls, at the roots of coarse grass, or in tufts of moss, and, retiring within the shell, they close up its aperture by a membranous or calcareous epiphragm, which serves, at the same time, to fix or cement the shell to the wall or body against which it rests. At the same period, the aquatic tribes descend to the bottom of their ponds and ditches, sink a little in the soft mud, and cover over the mouth of the shell with a transparent gelatine. In general, when the temperature of the air sinks below the 50th degree of Fahrenheit, cold-blooded animals begin their winter slumber, and, previously prepared by that instinct which operates as wisely as if right reason had fore- seen the coming evil, they gradually, with the increasing cold, sink into a state which resembles more the stillness of death than the quietness of sleep ; a state without motion, or feeling, or sense, or heat, and in which the heart and lungs, the vital organs, perform their functions more and more feebly, until they also rest still in the general quiescence ; and in this deathlike condition these animals continue " for five, six, seven, or even eight or nine months, according to the climate and season," until the genial warmth and dews of spring recall them anew to life and action. M. Gaspard has given a minute and' a very interesting * " The marine Mollusca probably migrate in part from the shallower to the deeper waters in cold winters : many, however, hybernate." {^Duncan I 3 116 'Natural History of Molluscous Animals : — account of the hybernation of Helix pomatia, in the first volume of the Zoological Journal ; to which I must refer you for the particulars. This species forms, by aid of its foot and a very glutinous secretion, an excavation or nest, in which it buries the shell, and it then closes the aperture with a thick calcareous epiphragm, and with several interior membranous partitions, which are more numerous at the end than at the beginning of winter, and in the snails inhabiting the moun- tains than in those found on low ground. Thus buried and enclosed, it passes six months in a state of total torpidity ; for the only indication of irritability perceptible during this period is a slight contraction of the collar of the mantle when touched, on removing the epiphragm. He found that there was no digestion ; the heart at first beat feebly, and with a very slow pulsation; but at a later period it was found to have stopped, and the circulation was entirely suspended; respiration ceased ; no animal heat, which even in the sum- mer, when respiration and circulation are most lively, does not exceed one degree above the surrounding atmosphere, was evolved; no secretions nor wasting function went on, neither any growth or reproduction of new parts. " In our climate, it is about the beginning of April, soon after the song of the cuckoo begins and the swallows appear, that the snails leave their torpid state; varying a little, however, according to the season. The mode by which their escape from con- finement is effected is simple and easily comprehended. The air which is contained in the different cells, and which had been expired on the animal withdrawing itself farther and farther into the shell after the formation of the operculum, is again inspired, and each separate membranous partition broken by the pressure of the hinder part of the foot pro- jected through the mantle. When it arrives at the calcareous operculum, the animal, making a last effort, bursts and detaches its most obtuse angle. Then insinuating by little and little the edge of the foot between the shell and the operculum, it forces the latter off, or breaks it away. The animal then comes forth, walks, and immediately begins feeding, with an appetite excited, doubtless, by an abstinence of six or seven months." (p. 99.) Such is M. Gaspard's account of the reviviscency of Helix pomatia, and the process must be still simpler in the other species; for they have merely to rupture a single horny or semigelatinous membrane. But there has been a difference of opinion relative to the source of the air which is first respired. Gaspard, you will observe, says that that portion which is confined between the layers of the epiphragms is their Respiration, 119 the first inhaled ; and, in coincidence with this opinion, we must infer that the species with a single membrane respire in the first instance the air behind it, and then, by their own efforts, burst their prison wall. A very different explanation of the process has been advanced by Sir Everard Home. He says : — " When warmth and moisture are applied, the mem- branous film (of the garden snail) falls off; a globule of air that remained in the cavity of the lungs becomes rarefied, and forces its w^ay out, and admits of fresh air being applied to these organs."* {Comp, Aiiat.^ vol. iii. p. 156.) I suspect that more of fancy than of observation enters into the baronet's theory; for were the rarefaction of the contained air, and its egress through the pulmonary aperture, all that was neces- sary to shake off the winter slumber, this would be done on several days in winter and in early spring, when the sun shines brightly and the atmospherical temperature is high enough to produce the effect, often higher, indeed, than it is when they begin, in the appointed time, to leave their hybernating retreats. If, says M. Gaspard, individuals of Helix pomatia " were exposed during the winter to a dry heat of from 60° to 100° for several days, or even weeks, not one made its appearance; whilst, on the contrary, those which were placed in a deep recess, the regular temperature of which was 50°, came forth in April, or at the beginning of May, without any increase of temperature." Dr. Turton, on the other hand, maintains that the doctrine of Gaspard is equally untenable ; for that the direct commu- nication between the external air and the animal within its shell is never interrupted, but on the contrary preserved, by means of a small aperture in the epiphragm. His words are : — " But, upon examination, it will appear, that in the * In the following extract Sir E. Home repeats his hypothesis in a more detailed manner : — "It is curious that, although respiration is necessary for carrying on the functions of life, it is by no means so for the con- tinuance of its existence. The garden snail illustrates this fact in the most satisfactory manner. When the temperature of the atmosphere sinks below a certain degree, this animal places itself upon a solid body, that it may not be liable to fall off: it then forms an operculum of mucus, by which respiration is stopped, and the animal remains hermetically sealed up till warmth and moisture dissolve the mucus by which the animal was fixed to its place ; and a globule of air retained in the lungs, which consist only of one cell or bag, being rarefied, escapes externally, restoring the communication with the air of the atmosphere which rushes in, and the action of the heart is renewed. If it is admitted that the application of oxygen to the muscles of the heart is capable of stimulating that organ, nothing can be more simple than the mode in which this is effected : the oxygen of the atmosphere is absorbed by the blood in the lungs, and the closeness of the ventricle of the heart to the lungs permits the oxygen to penetrate to the heart." (Comp. Anat.y vol. v. p. 129.) 120 Natural History of Molluscous Animals, centre of this epiphragm (of Helix pomatia) is an exceedingly minute orifice, communicating with an umbilical cord, which is connected with a fine placenta-like tissue of vessels, pene- trating into the pulmonary cavity itself; and this minute ori- fice, although not large enough to admit a drop of water, is of sufficient capacity for the passage of that quantity of oxy- genated air necessary for the purposes of extremely slow, but not totally extinct, respiration. If this orifice be covered over with a coat of wax or varnish, so that all possible con- nection with external air be excluded, animal life becomes altogether extinguished, never to be again restored. We have observed this minute puncture in the winter covering of the H. ericet5rum and some others ; and it is probable that all whose aperture is closed during the cold season only, are fur- nished with this beautiful apparatus for the preservation of life." {Manual of Land and Freshwater Shells, p. 46.) I re- commend you to examine into those very interesting state- ments ; and, if your own observations confirm them, they will materially alter some inferences which have been drawn from Gaspard's experiments, and adopted by us, in reference to the total cessation of the action of the lungs and heart. That snail does not reach this northern latitude; but I have exa- mined, too carelessly however, the epiphragm of Helix aspersa during its hybernation, and always find a small aperture in it ; and also, in the aquatic tribes, I find a larger hole in their thin winter operculum, intended, assuredly, to keep up the communication between the pulmonary cavity and circum- ambient medium in their season of repose. There is something admirable in this curious adaptation of the economy of the hybernating creatures to their situations ; for otherwise they could not live beyond a single summer in the countries which they now inhabit with impunity to them- selves. If, during their active state of existence, you were to keep a Limneus, or any other aquatic pulmoniferous species, immersed in water for only one short day, it would die irre- coverably; but it remains under water, perhaps with the surface frozen over, for three or four months uninjured, when the system has been prepared, in autumn, for the change. And so of the land kinds : they perish if deprived of air for a few hours only in summer, or if exposed to an artificial cold not lower than the cold of winter; but in a state of hyberna- tion they respire, if any, such a small quantity of air as is not to be appreciated, and brave our longest and severest frosts without peril and without pain.

On Structure, and its adnptedness to Economy in the Annulate Animals, By il. The most advantageous occupation for man is the study of the works of his Creator ; this study is also the most natural, and consequently the most gratifying. Man delights to en- quire into the means employed to accomplish appointed ends; he possesses an innate desire to discover the causes of those ob- vious phenomena which are continually attracting his attention. It is but too frequently the aim of those who instruct youth to repress this desire, this thirst for natural knowledge, sup- posing it likely, if encouraged, to interfere, in after-life, with the pursuit of power and riches, which are generally the only desiderata held up to our youthful hopes. It should be far otherwise; the expanding mind, like the growing body, should be copiously supplied with wholesome nutriment, else its tastes become vitiated and its power weakened. There is nothing which enables an ardent and aspiring mind to form so just an estimate of itself, as does an idea, however imper- fect, of something greatly superior. Now, that mind must be lost to the power of thinking, that cannot trace in the circu- lation of the blood, in the conversion of an egg to a chicken, or in the reproduction of a spider's leg or a lobster's claw, the design and superintendence of an intelligence infinitely above its own. Let man enquire into these things. As he imbibes great and important truths in natural history, he be- comes deeply imbued with a sense of his own insignificance. His first safe step in knowledge is the assured feeling of his own utter ignorance. I have long desired the opportunity now afforded me, of addressing readers among whom many will be willing to consider themselves learners. For the learned I have no no- velties in store. I address myself more particularly to those yet in the morning of life, whose enthusiasm of enquiry has received no chill from the unsatisfactory sophisms and pe- dantry of soQie of the self-elected dictators in natural history. I am no dictator, but a fellow enquirer : my solicitation is, " Come with me, a lowly and unworthy son of science ; come with me, and let us together meditate on the wonderful works of our Creator. Let us examine together the structure of one branch of the animal kingdom. Let us trace the pecu- liarities which distinguish it from the other branches. Let us see how beautifully these very peculiarities are adapted to the parts in the creation which these creatures are designed to perform." 122 Relations of the Structure of In this research, Professor Grant, hi his admirable lectures at the London University, and Mr. Newman, in his letters on the Osteology of Insects, in the Entomological Magazine, have both preceded me; but, by restricting myself to much narrower limits than the former, and avoiding altogether the tech- nicalities of the latter, I trust it will not be difficult to steer a middle course, without the least interference with either of them. Animals are termed annulate, from having the exterior of their bodies divided into rings. The name may be considered as applicable to every creature commonly known as an insect; flies, bees, wasps, beetles, grasshoppers, dragon-flies, moths, butterflies, fleas, mites, spiders, centipedes, scorpions, lob- sters, crabs, shrimps, &c., &c. In these creatures we find the seven principal systems of organs observable in larger animals and in man : the organs of sensation, or nervous system; the organs of support, os- seous or bony system ; the organs of motion, or muscular system; and these three we shall find, throughout their varied developement, peculiarly connected and dependent on each other : the organs of circulation, or vascular system ; the organs of respiration, or respiratory system ; these two, also, being dependent on each other : the organs of nutrition, or digestive system; and the organs of reproduction, or generative system. We frequently find, in the writings of men entitled to the greatest respect, a kind of triple division made of the organs of sensation — the brain, the nerves, and the organs of the senses. Let us examine whether this division really exists. Vegetable physiologists have shown that the delicate flowers of a plant are but the perfected continuation and completion of the same rind which originates in the root and clothes the stem. Now, it appears to me, that the nerves originate in the brain, which is their root, branch through the body, and blossom in the organs of the senses ; and that, therefore, each peculiar character they assume is but the modification of the same system. Taste, smell, hearing, and sight must, in this case, be considered as nothing more than variously perfected attenuations of the same nerves which are distributed through- out the body; in other words, varied developements of the power of feeling, wonderfully contrived to arrest, ascertain, and apply the properties of substances, effluvia, sounds, and rays of light. The nerves, when terminating simply in organs of sensation, appear to be endowed with a double capacity : they convey the impression of the presence and form of inert Annulate Animals to their Economy. 123 matter, and of pain from the quality or motion of matter. One impression is not the excess of the other ; the scald of hot water, or the entrance of a bullet, conveys no impression of form. We find that, the more concentrated the brain, as in vertebrates, the more perfect are the organs of the senses. Let us select, for example, a mouse: mark the bright eyes, the attentive ears, the inquisitive nose, all taking instant cogni- zance of danger, or enquiring for means of support. Ex- quisitely slender, infinitely ramified, and tremblingly alive to pain, are the nerves which serve for the sense of touch. Of vertebrated animals, moreover, it is a distinguishing character that the separation of the brain from its branches, the nerves, causes death. In annulates, the nerves are nowhere concentrated into a mass analogous to the brain of man, but are gathered up into knotted strings, two principal series of which pass longitu- dinally throughout the body, extending their branches into all the limbs. The head, in such a formation, is therefore no longer the seat of life, or essential to life, but every segment and every limb is possessed of, and retains, vitality in equal proportion. This diffused brain, like the concentrated human brain, appears to be the organ governing sensation, and, like that, also, seems, in its principal masses, without sensation in its own self; and its radiations do not, except as organs of the senses, generally, as in vertebrates, find their way to the surface. From these circumstances it may be conjectured, that, had we the means of ascertaining, we should find that annulates are altogether without that acute sense of pain which we possess. The organs of the senses, also, are less perfectly developed. If we select the lobster as an example of a large and tolerably perfect annulate, and examine its dull eyes, its simple vestibules of ears, we shall instantly be struck with its inferiority in these respects. Another Jesuit of this difference in organisation is, that creatures having the concentrated brain enjoy, in a greater or less degree, that wonderful reflecting meditating power possessed in so glorious a degree by man ; whilst the whole of the annulates are di- rected in all their actions by a blind unreasoning instinct. The annulates, then, may be said to be unprotected by reflec- tion, and for the most part unguarded by the senses. The lobster is driven by the waves and dashed among the roughest rocks ; the heedless beetle flies in our very faces ; myriads of insects are forcibly impelled by the winds against the hardest substances ; myriads are beaten to the earth by rain ; myriads are cast, unresisting, into rivers and lakes. Yet they escape Ig-i delations of the Structure of from all this unharmed, and, by a simple and beautiful con- trivance, are enabled to abide their time, to exist till their destiny is complete. They are provided with an exterior skeleton, a covering which wraps them as a mantle and shields them from harm. The covering of annulates is completely bony; it is, in every respect, a substitute for the internal skeleton of verte- brates : like that, it serves for the attachment of the muscles and support of the whole frame. It bears uninjured the con- tact of the roughest and hardest substances. It enables its possessor to endure that rough usage which the more perfect developement of the organs of the senses in vertebrates en- ables them to avoid. When we consider the destiny of annu- lates, principally food for each other, or for larger animals, we cannot wonder that the same nicety of reasoning power and of sensation, which vertebrates enjoy, has not been given them. To what good purpose would it have tended, had nature furnished creatures so obviously the sport of wind and wave, so obviously liable to continual loss of limb, so ob- viously designed the living food of others, with that constant apprehension of danger, and that acute sensation of injury, which we ourselves possess? Certainly to none. Their brain does not reason, their covering does not feel. This bony covering or skeleton of annulates gives them shape, and, like the skeleton of vertebrates, affords the naturalist some of the best characters for distributing them into groups. It is transversely divided into thirteen segments, or rings ; whence the term annulate. To each of these rings names have been lately given by Mr. Newman, in the work before alluded to, the Entomological Magazine. Attached to these rings are the organs of locomotion ; and the number, position, and de- velopement of these are very various ; and a knowledge of these variations is, consequently, not only highly interesting, but absolutely essential to the right understanding of the economy and classification of these wonderful creatures. The muscles, in annulates, are very various in their pro- portions; we shall, however, always find them beautifully adapted to the labour they have to perform ; and their degree of developement operates immediately on that part of the skeleton which covers them, by a visible increase or decrease in size of the bony plates of which each segment is composed. It not unfrequently happens in glowworms, moths, &c., that, in the same species, one sex is provided with wings and the other sex wants them entirely : in these cases we find that, in the females, there is a tendency to equal developement of all Annulate Animals to their Economy. ] 25 the segments; whilst, in the males, the wing-bearing segments are both increased in magnitude and altered in form. By dissection we find that those muscles which, in the males, are essential to move and guide, with great power and rapidity, the organs of flight, are become obsolete, or rather repose in a quiescent and undeveloped state, in the inactive females, which are doomed never to traverse the realms of air. Ob- serve, again, the common ant. Compare, in a winged ant, the wing-bearing segments with the same parts in a worker which is constantly without wings, and you cannot fail to be struck with the difference in their size. In autumn, large wingless ants are not uncommonly seen w^ith the wing- bearing segments precisely similar to that of the winged ants: these are females which have once possessed wings, but which have, on settling down to form a new colony, stripped off these organs as useless in the subterranean life they are about to lead. We must, however, in making a law for the appropriation of muscular developement to the extent, strength, or activity of the organs it has to govern, be ever on the watch for the operation of yet more positive and unvarying laws, which may supersede the operation of the one we may assume. Specific gravity is one of these. The lobster, which is so nearly equal in weight to its own bulk of salt water that it floats in it with perfect ease, can, in that medium, move its ponderous claws with the greatest activity ; but in the air, unless the governing muscles, and consequently that portion of the body which they occupy, were increased at least ten- fold in magnitude, these claws would be unwieldy and useless. If we hold a lobster up by the back, we find that these claws are too heavy to be employed : the forceps will pinch, and that severely, but the object must be placed purposely in their way. the animal possessing no muscles which will raise them sufficiently to seize an object on a level with its head. Still we must not conclude that the annulates inhabiting water are invariably thus unfitted for exertion in another medium; for this is by no means the case; many possess a form and organs equally adapted for living in the water or on the land.

Oy The animal in the shell, natural size, by The animal removed from the shell, natural size, c, A single filament of a bran- chial tuft, magnified. This splendid worm was first discovered by Colonel Mon- tagu ; and although it has been since noticed by several con- chologists, yet as none of them, except Mr. Berkeley, has taken any notice of the animal, it may not be deemed an un- interesting subject for these illustrations, particularly as the figure alluded to is contained in an expensive work, in the hands, perhaps, of few readers of this Magazine; and the figure itself I was never able to procure. Serpula tubularia is the largest species of its genus found Sei'piila inhuldriai, 127 on our coasts, and has been usually considered among the rarest. The shell is from four to five inches long, and some- times more, but the animal tenant does not exceed three. The body of this is vermiform, flattish, distinctly annulated, of a reddish-orange colour, stained v^^ith irregular blotches, from the opacity of the viscera and their contents. The anterior extremity is obtusely truncate, and on it are placed two large fan-shaped bundles of filaments of a yellowish colour, beauti- fully marked with scarlet spots. The filaments in each bundle are numerous, and are united at the base into a fleshy stalk, which again is directly connected with the head, on which also some scarlet spots are distributed. Each filament is simple, but pectinated along the internal edge with a close series of short blunt processes, which are not visible without the aid of the magnifier. The anterior third of the body is covered with a thin brown membrane, divided on the ventral aspect, where the margins are free and somewhat undulated ; they are also furnished on each side with seven little brushes of bristles, which appear to be partly retractile. These brushes are placed at equal distances ; the anterior, perhaps, a little closer; and at the side of each there is a scarlet bar or spot ; the bristles in each are very slender, numerous, yellowish, smooth, and acutely pointed. The remaining portion of the body is divided into very numerous short rings, on the sides of each of which there is a thickened puckered spot, something like a beginning tubercle ; it is grooved along the back, and tapers to a rather obtuse end, where it is sparingly clothed with some delicate hairs. The ventral surface is convex, smooth, and flesh-coloured ; and the anus is terminal, there lying underneath it a long white spot, produced, perhaps, by some dilatation of the intestine. The shell, as we have said, is from four to five inches long, and as thick as a goose-quill. It is cylindrical, gradually tapered at the posterior end, where it becomes more or less flexuose, and where it is affixed to the foreign body whence it takes its origin. The attachment in our specimen was broken off. The colour is opaque white, and the smooth sur- face is partially covered with corallines and smaller Serpulae. The margin of the aperture is circular, smooth, and even ; the other extremity is closed. I kept the individual here figured for several days by me, to observe its motions. The worm would sometimes remain for hours concealed in the shell : and, when it ventured to peep out, the branchial tufts were sometimes slowly and cau- tiously protruded, and sometimes forced out at once to their full extent. After their extrusion they were separated and ex- panded, as in the figure, and lay at perfect rest on the bottom 128 Illus'rations i?i British Zoology: — Serpida tuhuldria, of the plate, in unrivalled beauty, and an object of never failing admiration. The worm, however, seemed never either to slumber or sleep; for, on any slight agitation of the water, occasioned, for example, by walking across the room or leaning on the table, it would at once take alarm, and hurriedly retreat within the shelter of its tube. It was never off its guard, and would often, when lying apparently in calm indulgence, suddenly withdraw, in evident alarm, without a cause but what was gendered by its own natural timidity; for the phan- toms of dreams are not, it may be, the visitants only of higher intelligences, but come as they like, in a fearful or cheerful mood, even to these lower things. It never pro- truded itself farther than is shown in fig. 23. a ; and, after becoming weak and sickly, it first threw off one half of its pride, a branchial tuft ; and after several hours the other was likewise cast away, when the poor mutilated creature buried itself, still living and to live for a day or so longer, in its own house and cemetery. The anus is at the posterior extremity, as in other worms ; but the remains of its food are ejected from the mouth of the shell, in small egg-shaped pellets. By what contrivance this is done, I do not know: are the pellets forced along the dorsal furrow? The fan-shaped fascicles are its breathing organs ; and the brushes of bristles in the sides of the mantle are the organs which enable it to move up and down the tube, assisted, undoubtedly, by the rough spots on the margins of the body. This is traversed down the centre of the back with a vessel filled with red blood, and which sends off minute branches to almost every ring. Mr. Berkeley has attempted to draw a distinction between Serpula arundo and tubularia. The former, he says, may be known "by its more slender form and delicate substance; 'neither is the aperture expanded, as in S. tubularia. The animal differs from S. tubularia in its oblong dorsal area; while that of the latter is much attenuated behind ; and in the absence of the operculum." Now, if we turn to Montagu, the original describer of S. tubularia, and whose name therefore ought to be retained, we shall find him telling us that the animal has no operculum ; and his description of it agrees exactly, so far as lam able to judge, with Mr. Berkeley's. Indeed, it seems to me, that this very acute and excellent naturalist has confounded the S. tubularia of Montagu with the S. wrmicularis of authors : for, on this supposition, his remarks on their distinctive characters will be found per- fectly correct and decisive.

Klotzsch, of drying Specimens of Vungijbr Preservation in Herbariums, By William Christy, Jun, Esq., F.L.S.,,&c. &c. Sir, If the following brief notice of an easy and successful mode of preserving Jungi should be deemed worthy of a place in K 2 132 Mode of drying Specimens ofYungi your pages, I shall be gratified. I enclose, for your inspec- tion, some specimens, which have now been prepared between three and four years, and which, you will, I think, allow, give a very fair idea of the i^ungi in their growing state. I am, Sir, yours, &c. Clapham Boad^ Teh, 1834. W. Christy, Jun. The extreme difficulty of preserving Fungi, so as to give any idea of their colours or forms, except by the cumbrous and expensive plan of putting them in spirits, must have struck every one who has paid any attention to this beautiful branch of botany. When on a visit, several years since, to my excel- lent friend Dr. Hooker of Glasgow, I became much interested with a mode which M. Klotzsch (who had then the care of the doctor's herbarium) adopted to preserve various Fungi. M. Klotzsch was good enough to give me some lessons on his plan, by which, I am sorry to say, I have as yet profited little ; but I have done at least enough to satisfy myself that it is not only practicable, but easy and very successful. Preserving Fungi in spirits, besides the expense for spirit and glasses, is of little use as regards their colours ; whereas the plan alluded to preserves the colours, in most instances, in their native brilliancy. M. Klotzsch published, I believe, an account of his plan in that valuable work the Botanical Miscellany ; but as that work, from its comparatively high price, has a much less extensive circulation than your Magazine, I think I may be rendering a service to some of the lovers of Fungi by com- municating, through your pages, a sketch of the mode as known to myself. The plan which, in pursuance of M. Klotzsch's instructions, I have adopted, is as follows : — With a sharp knife I divide the fungus through the pileus and stipes into two parts, one rather larger than the other. From the inside of the larger portion I take, in the same manner, a thin slice [Jig. 28.), which thus affords a complete vertical section of the fungus, showing the peculiarities in the structure of the stipes, pileus, and gills. The remaining por- tions are then to be treated as follows : — Carefully separate the pileus {Jig, 29, a) from the for Preservation in Herbariums. 133 29 Stipes (b) ; scrape out the gills, and, where the fungus is very fleshy, re- move also a portion of the solid part of the pileus. The vertical section, and the respective portions of pileus and stipes, are then to be placed in blotting-paper, and submitted to pressure, as is usual in drying plants. It is, however, advisable to expose them to the air for a short time, in order to wither them, and also to apply the pressure at first gently, as they are otherwise liable to split and crack. If the fungus is of a succulent nature, M. Klotzsch recommends drying them within the influence of the fire, and changing the papers several times a day. When dry, the vertical section, with the pieces of stipes on which are to be placed the respective portions of pileus, may be glued upon paper, and the whole will give a very good idea of the general appearance of the fungus, (fg. 30.) Where a sufficiency of plants of a species occur, sections may be made of them in their different stages of growth, showing the various degrees of developement. {fg, 31.) The very vivid colours of some jFungi (^garicus emeticus and others), are, in specimens dried in this man- ner, beautifully preserved, as well as the forms of some of the most fragile and delicate species. The advantage which this mode of preservation possesses over all others, by enabling us to place the specimens in almost as little space as other plants in our herbaria, renders it worth the notice of all botanists. I trust I have made myself intelligible ; but any one desirous of farther information would doubtless find it in M. Klotzsch's paper. Not having the Botanical Mis- cellany at hand, I can only speak from me- mory; but I think the paper will be found in the fifth or sixth number of that work [Vol. ii. p. 159. t. Ixxxiii.] 1 34 Shm't Coimmini cations i — The dried specimens of funguses sent by Mr. Christy are affixed to four tablets of paper, and are thereon named ^gari- cus squarrosus Miiller, A. peronatus BolL^ A. emeticus Schaejff] A* pratensis Pers. The place and time in which they were obtained are added : the time, as to the year, is 1830. Their appearance on the paper is very pleasing, and their character- istics seem most satisfactorily exhibited. A» squarrosus is illustrated by one specimen, very young ; a vertical section of another, a little older ; a profile of one full grown ; and a vertical section of another full grown : this last shows the relative thickness of the pileus, the depth of the gills, and the structure of the stipes. A. peronatus is shown in two pro- files and two vertical sections : A, emeticus by a profile and two vertical sections ; the external colour of the pileus is a fine fulvous red : A, pratensis by two profiles, and four ver- tical sections of as many plants in progressive stages of growth. The condition of all the specimens proves the excel- lence of this mode of preparing them, and this must render a knowledge of it very useful to every student of F(xugu We hope to see a descriptive notice of it given in the volume on the funguses of Britain, now in preparation by Dr. Hooker : it will then be under the eye of every one who may endeavour, by the help of that work, to attain an acquaintance with these plants. — J, D, Art. VIII. Short Communications, Mammiferous Animals. — Fooc at Deptford, — Sir,lscarcely know whether you will think it worth noticing among your Short Communications, that a fox should have established an " at home " within four miles of London Bridge. My garden is one that is rather remarkable for having its own way. Some years ago, I took a great deal of pains to introduce into it all kinds of wild flowers, shrubs, and trees, and these have grown uninterruptedly and formed large masses of underwood, which, being principally composed of bramble and dog-rose, have established a seat of empire not easily to be shaken. What is termed, vulgarly, a tide-ditch, elegantly, a canal, which the river Thames fills at high water, surrounds more than two thirds of the garden. In this spot a fox established his abode, and made himself very happy for more than six weeks. The neighbours lost their fowls, ducks, pigeons, and rabbits. Many a long face have I seen pulled about their losses ; many a complaint of the " howdaciousness " of the rats, the cats, the thieves, and the new police ; in all which I Mammiferous Animals. 13.5 took very great and sympathising interest. In the mean time, I used to sit in my summer-house of an evening, and watch master Reynard come out of his retreat ; and a great amuse-^ ment it was to me. He would come slowly trotting along, to a round gravelled place, where four paths met; then he would raise himself on the sitting part, look about, and listen, to ascertain that all was safe, and, being satisfied of this, he would commence washing his face with the soft part of the leg, just above the pad. After this operation was well per- formed, he used to lie flat down on his belly and walk delibe- rately along with his fore legs, dragging the rest of his person along the gravel, as though it were quite dead, or, at least, deprived of motion ; then he would run round and round after his brush ; which I could see he sometimes bit pretty severely, and on such occasions he would turn serious all at once, and whisk his brush about in a very angry manner. Poor fellow I a neighbour happened to see him cross the ditch by moonlight into my garden with an old hen in his mouth. The outcry was raised; a search was demanded. Next day there came guns, dogs, pitchforks, and — neigh- bours ; the upshot of all which was, that poor Reynard/s brush is dangling in my little wainscotted room between an Annibal Caracci and a Batista. — E, N.

I lately met with a case of this disease, mentioned in a recent work on the West Indies. The writer states that he saw a slave who was in the habit of eating earth in large quantities. He seemingly considered it a luxury. Yours, — J. M. Haughton le Skerne^ County of Durham, August 20. 1833. A somewhat large, and a very interesting, collection of in- stances of depraved appetite in the human species will be found in Good's Study of Medicine. Humboldt, in his Tableaux de la Nature, informs us that the Otomacs sometimes appease their hunger by distending their stomachs with prodigious quantities of slightly baked clay. K 4 136 Short Corrmmnkations : - — In farther illustration of this subject we present Some Instances qf^ depraved Appetite in the domestic Babbifj taken from a communication on the habits of this animal, con- tributed by our correspondent, Wm. G. Barker. After he has described the usual articles of food with domestic rabbits, he thus proceeds : — They will drink ale with avidity, but in this matter, I must own, they show much greater sense than pigs, two or three spoonfuls sufficing them. But the appetite of the rabbit ap- pears to have no bounds : vegetables are their natural food ; but I unhesitatingly assert that they feed upon animal sub- stances both dead and living. Some ievf of your readers will undoubtedly feel surprised at this declaration : I have, how- ever, seen it myself. Depravity of appetite is far from being peculiar to the rabbit. If time and space allowed me, I could refer to a kestrel (Falco Tinnunculus L.), now in my posses- sion ; and to some remarkable anecdotes of hyaenas, by Pro- fessor Biickland, in his valuable Reliquice Diluviame. Of these in their season. Many, I may say the whole, of your readers have, in all probability, kept rabbits in their younger days, and they must, therefore, be well aware that the male has so great a propensity to devour the young ones, that breeders of rabbits always remove him from the doe, at the time of kind- ling. As soon, however, as the young ones can see, there remains not the slightest danger to them, from him * ; on the contrary, he will sometimes display great ferocity in defend- ing them from their enemies. Far otherwise the doe : if the young are born dead, as they not unfrequently are, they are, in most cases, immediately devoured by the mother ; and some have this unnatural propensity in so strong a degree, that the offspring, though born alive, share the same fate. I have known one remarkable and solitary instance of a doe who killed her whole brood, when two months old. They were tolerably fine young rabbits, lively, and appeared healthy, but there was something in them which exasperated their mother, for she seemed wholly bent upon destroying them. It was not done at once, nor in a few hours, but occupied her about ten * I have known an instance of a male inducing the death of a young rabbit, between a third and half grown. The latter, and all those of the same litter, were moving about on the floor of the apartment, out of their hutch, when the male forced open the door of his own hutch and sprang among them, and bit through the skin of one of them behind the shoulders. In the struggling of the young rabbit to get away, and the detention of it by the male, the skin, in an instant, was torn off a considerable portion of its back, although not wholly detached from the portion of skin left re- maining; insomuch that it was judged proper to kill the little rabbit instantly, and this was done. — J. D. Mamm{ferous Animals. 137 days. I do not, however, mean that she was employed the whole of that time in the operation of slaughtering, as two or three days intervened between the death of each. It was painful to see her chase the little unoffending creature round the hutch, in frenzied passion, and literally thirsting for its blood ; but there was no alternative : to remove it from her was certain death, to allow it to remain was to leave it in the jaws of de- struction : one after another, they all were slain. One of those which perished in this manner had recipived a wound from her teeth and claws in the side, through which the bowels protruded. As soon as it was dead, nay, even before the breath had left the mangled body, the unnatural brute, and the surviving young ones, eagerly devoured the whole of the carcass, and even the bones, leaving nothing of their horrid banquet but a portion of the skin, the legs, and, if I mistake not, the head. Until then, I had thought maternal love inviolate in the brute creation. I have since found, from other sources, that they share the depravity of man. If any person presumed to touch one of the young rabbits above mentioned, its death was sure to follow almost immediately. What renders the above account more remarkable is, that the animals had just received their morning's allowance of food ; but the deaths ge- nerally happened after feeding time. May I here be allowed to ask some of your medical readers, might not this extraor- dinary and unnatural depravity arise from some disease in the organs of smell, and, perhaps, in the stomach also ? The mother invariably examined them, which rabbits always do, by smelling, previous to commencing her attack. — Wm, G. Barker, East Witton, March 22. 1833. GoGseherry-eating Dogs. (VI. 364.) — Grammarians tell us of three degrees of comparison: J. M.'s dog is positive; J. D.'s is comparative ; mine is superlative. The book people, and the technical people, and the anti-Natural History Maga- zine people may laugh at all three, dubbing us, by way of epithet, stultus, stultior, sttdtissimus : but no matter ; I cannot let my poor old favourite Crib, and his favourite appetites, be forgotten like a common dog or a common propensity, when the oat-cracking, gooseberry-crushing candidates for immor- tality are eternised by Mr. Loudon. My friend Crib was a dog of talent and discerning; he was bred at Ely, and educated at Cambridge; having graduated with his master, as Bachelor of Arts, in the year 1821. Like Ulysses*, he was one of the ugliest and most eloquent of animals, and his very exuberance of black * " l^on formosus erat, sed exaXfacunduSy Ulysses." Ovid. 138 Short Comrmmications : — whisker and eyebrow, and his unceasing bark, made him noticeable by day and night. I never was given to such pas- times, but I am told he would dive after a waterfowl, and draw a badger; accomplishments some years since in high odour with puppies at the Universities ; now, I hope, in these reforming days, abandoned for more philosophical and classical pursuits. Crib, therefore, did not want courage. He was Cerberus from that time till his death, in 1831, at my resi- dence in Suffolk, and during those ten years became cele- brated as a guardian by night, a companion by day, an enemy of poachers, the friend of cats, and, like J. D.'s Toby, a mighty connoisseur in gooseberries. I have no time here to tell all his adventures with a monkey and a snake, which I kept with him as playmates ; but I may add that Toby, with all his " taste" and " well-bred" enjoyment, does not appear to have arrived at Mr. Crib's state of renown. I found him, one day, in the garden, performing Toby's feat of gooseberry- crushing ; thereby discovering the depredator, whom we had long unjustly considered a two-legged dog. In his heedless- ness, he swallowed a berry, in which was a wasp. The wasp stung his throat; and the agony, to judge by his grimaces, must have been intense. From that hour he became the mortal enemy of the whole race of wasps, and his skill in destroying them was remarkable. Baring his teeth by the withdrawal of his lips (V. 386.)j he would wait under his favourite bushes till the wasps appeared, and then, snapping at them, he contrived to kill them without injury to himself. I have seen dozens of those marauders mingled with the gooseberry husks under the bushes, but I never recollect an instance of their doing their destroyer an injury after the first insult. The dog never forgot the circumstance ; a wasp ever after became an object of pursuit with him. This, however, was not all : amongst other things. Crib, like his namesake of the ring, was a tippler as well as boxer ; and nothing de- lighted him so much as a saucerful of warm elderberry wine, which he regularly partook at Christmas with the family. I have seen him, more than once, *' pretty considerably decent tipsy," as they say in America ; but justice compels me to say that this was his only failing: a more moral dog, in every other respect, never lived, and one more regretted never died. The day I left my native place, he laid himself down at the foot of my chair, burst a blood-vessel, and expired. He sleeps in his quiet grave, under the shadow of one of the most splendid oaks in all Suffolk; and his epitaph might put to the blush many, perhaps, who may call its writer, for this MammiferoHS Animals. 139 mention of it, simpleton. — W, B.

Acts, possibly analogous, in the Lion and the Young of the Domestic Cat. — In playing with a cat, young enough not to refuse to play, it is observable that, when the cat has enclosed your hand in its (all four) paws, and has also applied its mouth to your flesh, ready to both lacerate and bite you at the very next tickle, should you adventure one more, yet, if you do not adventure one more, and hold your hand perfectly still, you may usually save yourself the laceration and biting threatened you, and, at the cat's own good pleasure, be entirely released from its grasp. I have fancied there is a similarity in this conduct of the cat of our hearth, and that of the lion to Major Woodhouse, as described bv Mr. Waterton. (p. 5.) J.D. A few Words on Cats.— -J, W. L. (V. 275.) tells of a cat at Dorking, which never ate the mice he caught, but laid them at the feet of the first person he met. My father had a white male cat, about the year 1815 (when we resided at East Bergholt, in Suffolk), which was even more sportsman-like than his Dorking compatriot. In a meadow bank, behind the house, were abundance of rabbits; the cat would go thither, and bring away his game, even rabbits more than half-grown, and, without injuring them in any way, would take them into the house, lay them at the feet of any one he met, and retire to the door, to prevent the escape of his prey. This I remember to have occurred frequently, till, in one of his poaching expeditions, poor Tom was taken in a snare laid for his game, and delivered over to the executioner, to be done with according to game law. J. D. (V. 276. and 674.), X. (V. 674.), and Mancuniensis (V. 717.), speak of cats without tails. The last observes that they are plentiful in the part of the Isle of Man called '' the Calf of Man." This can hardly be, as the Calf of Man is a smaller island at the southern extremity of Man, and is not peopled or inhabited, save by the family of the person who has charge of the splendid lighthouse erected there. I do not exactly agree in the description given by Mancuniensis, though the tailless cats of Man are tall. When I was in the island, with some college friends, in the long vacation of 1820, we had much amusement with these curious creatures. I saw several in the huts of the peasantry, amongst the mountains, between Ramsay and Peel Town ; but as the honest people did not speak English, and we spoke no Manx, I learned nothing of their history there. But mentioning the subject to a person at Balla Salla, near Castle 140 Short Commwiications : — Rushen, and not very far from the Calf, I was informed that a vessel from Prussia, or some port in the Baltic, was wrecked many years ago on the rocky shore between Castle Rushen and the Calf, and that, on her driving close in to the land, two or three cats without tails made their escape from the bowsprit, and were taken by the wreckers ; and that these were the first of the kind ever seen in the island. I do not say that this is the truth, but I was told so ; and, if it be the truth, the original breed is not of Manx extraction, but must be sought out in the north of Europe. I do not agree, though, in the emend- ation of Mancuniensis, who recommends (V. 717.) reading " Isle of Man" for " Isle of Wight;" for Dr. Leach's cat might have been wrecked there, or imported thither, as well as its contemporaries to the Isle of Man. Whilst on the subject, I will allude to a tale which was told me when a boy, of an extraordinary instance of the powers of abstinence of the cat. I forget the minutiae of the story, but it ran thus : — A cat, which belonged to a vessel from the port of Mistley, in Essex (a place about four miles from East Bergholt), was missing when the vessel sailed from some har- bour in America, and no one could tell what had become of it. But on arriving in a part of the Channel where it was neces- sary to unfurl a sail that had not been employed till then during the voyage, the cat was discovered, in a sadly ema- ciated condition, in the folds of the sail, and, notwithstanding her long imprisonment, still alive. My informant was the late Mr. Dunthorne of London Street (a young self-taught artist, of rising and deserved celebrity, whose industry, taste, and acquirements, in spite of difficulties and want of " ap- pliances and means to boot," made him an extraordinary instance of the power of genius and talent, and would have wrought out for him a distinguished place in English bio- graphy, had not a too early death taken him away from us*) ; but I cannot now, in consequence of his having recently paid the debt of nature, appeal to him for further information. If, however, there be any feline Sadducees amongst your readers, I would venture to assert that this story may have been true, judging from an instance which I can fully attest by the evi- cence of self-experience, and the testimony (if required) of two or three friends. The Dutch commenced the siege of Brussels, in the revolution of 1830, in the month of Septem- ber. On the 24th of that month, they took possession of the house of my friend.

Mammiferous Animals. 141 barbarously destroying his furniture and drinking all his wine, shut up his cat, with the empty bottles, in a closet in the kitchen. As the family were driven out of the house at the point of the bayonet, to seek shelter where they could, no thought was taken of any thing but their preservation. On the 1 5th October (just 21 days afterwards), I accompanied Dr. Verstraeten and some friends to his house, to see the ruins, and, on descending to the kitchen, the door of the above-named closet was opened, and immediately the cat, which had remained there a prisoner since the battle, came bounding out with a look and a cry of hunger and joy. Dr. Verstraeten remarked himself, that the cat was supposed to have been lost or killed, and expressed his surprise at her existence so long without food. The poor animal could not have had any food (unless a mouse or two) during her im- prisonment, as the house contained nothing which had escaped the piratical hands of the besiegers, save a solitary bottle of preserved gooseberries, the only entire article in the house. The poor thing looked as wretched as possible ; but she de- voured most voraciously some food we procured from a house opposite, and lived to do justice to her deliverer from " durance vile." Since I wrote the above, I have been informed, by Captain T. Festing, R. N., of this place, that a favourite cat belonging to his family, which was transported from Andover hither, suddenly decamped, and, after being on his travels nine days, arrived, " hungry and sore bested," at his old quarters, having discovered his way across the country without a guide.

Some time after the appearance of the number of this Magazine for May, 1829, in which was given the first of the above notices, I was requested by a lady in this neighbourhood to examine a flying squirrel, a general favourite with her family. I found the upper incisors very much elongated, and inclined under the lower jaw ; rendering it out of the little animaFs power to take his usual food, as there was no possibility of the opposition of the extremities of the upper and lower incisors. I considered that the disease might be remedied, by removing such a portion of the upper incisors as would allow them to come properly in contact with those of the lower jaw. This I easily effected, by means of a pair of forceps. I have frequently seen the little animal since, and have had the satisfaction of observing him busily at work on his nuts, and of learning from his mistress that he has since that time taken his food as before the disease had occurred. — John Reynolds Roxsoe, Wimhorne, Dorset^ Jan. 1. 1834. Among the numerous individuals of the common squirrel ((Sciurus vulgaris L.) which occur in British woods, is one with a discoloured coat often seen? On January 10. 1834, 1 learned that one with a party-coloured coat had, at some time Birds. 143 previous, been several times seen upon the lawn at (Mrs. Southwell's) Wroxham Hall, near Norwich. — J, D, A Common Dormouse {Myoxus avellandrius L.), with me, eats, of its own choosing, the A^phis lanigera III, and the caterpillars of the Sphinx ocellata L, It is particularly fond of the grubs of the Balaninus nucum Get^mar, preferring, for the sake of them, the maggoty nuts to the sound ones ; and I have known it eat the small caterpillars which are found in blackberries and pears. Are these appetites morbid ones, from the animal's domesticated condition ? Cannot the animal be employed to avail us in gardening objects, as the caterpillars, &c., it might destroy would fully compensate the little damage it could do the fruit? — John Perry, jun, Godal- ming, Surrey, February, 1834. A Mole, of a beautiful silvery ash-grey Colour, with an orange Mark under the lower Jaw, and a Line of the same Colour down the Belly, taken in this Neighbourhood, was lately brought to me. — It is probably the same variety as that men- tioned in Griffiths's translation of Cuvier's Begne Animal as occurring in Germany ; and does not appear to owe this pecu- liar colour of its fur to the effect of age. Other individuals of the same variety, and some also white, have been occasion- ally taken by mole-catchers with whom I have conversed. — W. C. Trevelyan, Wallington, Jan. 28. 1833. The Singing of Birds at early Dawn in Summer-time. — The wonders and beauties which Nature displays Excite to devotion the soul ; Her wonders teach wisdom, her beauties prompt praise, Pure bliss is the fruit of the whole. When I lived in the cottage at the end of the garden that now adjoins the house I reside in, and my business called me sometimes earlier than I am now willing to leave my bed, I have been delighted in a summer's morning to hear the pleas- ing note of the goldfinch busy amongst the dew-bespangled foliage of the apple trees ; the blackbird, perched on the highest branches of the highest trees, cheering its mate with its song ; the lark caroling over my head ; joined by the deep bass of a contiguous colony of rooks. In moments like these, I have found myself elevated and inspired with pity for those to whom, according to their own declaration, " this goodly frame, the earth, seems a sterile promontory," to whom " this most excellent canopy the air, this brave o'erhang'd firmament, this majestical roof fretted with golden fire, appears nothing but a foul and pestilent congregation of vapours." At times like these, I have made resolutions to rise earlier, that I might the more fully enjoy the beauties and the harmony of nature : 1 44? Short Communications ; — but my propensity to indulge myself in the arms of Mor- pheus has too often gotten the better of my resolution. Larks always in fine weather hail the earliest dawn of day with their song, and sometimes sing before the dawn, as I have recently learned in a journey by the night coach (the Red Rover) from Cambridge to London. I and my fellow travellers were surprised to hear the singing of the lark as early as two o'clock on a frosty morning, on the 7th of May (1833). The subject furnished us with agreeable chat, and roused us from our inclination to sleep : before it was ex- hausted, we were greeted with the song of the nightingale and cuckoo. The house sparrow, as we approached near London, was chirping. The sun was rising. The metropolis of England was in view. We arrived at the Flower-pot (a sign suggested from nature), in Bishopsgate Street, almost forgetting that we had lost a night's rest. Birds, at least Singing Birds, are Lovers of Music. [VL 523.] — A goldfinch of neighbour 's, in whose room the Pri- mitive Methodists hold their meetings, always sang with the congregation, whether by day or night. I have observed the robin, when I have whistled to him, appear pleased, and listen with attention. My nephew , who plays on the violin, had a linnet that always appeared delighted when the violin was played. The early singing of the lark, of which I have spoken, was possibly owing to the bird's being aroused by the sound of the guard's bugle ; it was immediately after the guard's playing a tune that we observed the singing of the lark, in a field near Buntingford, the London side of Royston. Rustici. At " vernal dawn" the larks pour forth a concert of music as they sit on the clods. I witnessed this on April 16. 1833, in passing some lands sown with barley, three miles north of Cambridge : the barley was just visibly up. — J. Z). The small dark br 011071 Thrush of the Western Islands of Scot- land, which W. L. deems of an undescribed Species. (III. 238., note t, VL 218. 516., VIL 75.) — Mr. Blyth states, in VL 516., that I have mistaken the redwing ( Jurdus iliacus) for the brown thrush of the western islands. Now, I beg to say that the redwing, even at a considerable distance, is very easily distinguished from every other species of Turdus, by size, attitude, and general colour combined together ; for, although its watchful and listening air, and its colour, resemble much those of the fieldfare (T. pilaris), when this species is observed at a distance, yet it is so much less (being, indeed, the least of the genus), that there can be no mistake between the two. Besides, I have several times noticed it at a dis^ Birds. 145 tance, by its own peculiar and distinguishing mark ; namely, the large ash-coloured streak near the eye, so like that of the stonechat. The dark brown thrush that I first saw in the Lewis, and have so often observed passing north in spring, is a very sober and plain-looking bird as to colour ; and has nothing of the airiness and elegance of the redwing, being shorter and thicker ; and is very sparingly mottled on the breast. In fact, both as to shape and colour, it might pass for a large edition of the hedge sparrow (ikTotacilla familiaris). I have, I am sure, seen hundreds of them, and not a redwing among the number. Moreover, I would refer to a footnote [note f] affixed to a communication of mine, in III. 237, 238., where it is mentioned that Mr. Macgillivray saw this same brown thrush breaking whelks on the shore. It must be allowed that this enthusiastic and now skilful naturalist (from nought else that I can suppose but innate modesty) took it for granted that these thrushes were of the common species (Z*. musicus). With not one tenth of his knowledge, I, with all the rashness of a little learning, when I heard them singing on these desolate shores, guessed that they must belong to a different species ; and I hope I may be allowed to refer to and cite the above note. " I was greatly surprised to hear the song of the thrush resounding on all sides from the heathy and rocky banks of the sea (* wasting her sweet notes on the desert air ') ; but I have always suspected it to be another species, darker and less." And so I am, with all due defer- ence to Mr. E. Blyth, still convinced it really is ; and I beg that Mr. Blyth will not take it as anything like want of respect, when I use the freedom to suggest that there may be more things to be seen, among the moors and rocks and bosky glens of Scotland, than " he has yet dreamt of in his philo- sophy." What if there may be not only plants and birds, but two or three quadrupeds, that he has never seen ? But, I would like to know, who has seen the nests of the redwing there ? I request to add that the migratory birds, in their journeys, alternately, to their native homes and their winter abodes, seem to keep generally along the " back-bone of the country." The redwing, after all, I take to be comparatively a rare bird ; for, although I have seen redwings both in spring and No- vember, I have seen but few. It is in the upland glens of Selkirkshire, Tweeddale, and Dumfriesshire, and not on the plains of Lothian, the Merse, or " the Laigh of Teviotdale," that the flocks of female chaffinches, grey linnets, thrushes, starlings, and snowflecks are seen. I well remember the Vol. VII. — No. 38. l 146 Short Communications : — flock of grey linnets that used to congregate on the leafless branches of an old ash in my father's stack-yard, singing in lively and cheering concert, for eight or ten days, as they passed in November. * — W. L, SelJcirJcshire^ December 20. 1833. [See also in p. 175. of the present Number.] Owls capture Fishes for Food. — In addition to the instances of this fact already registered in I. 179., II. 288., V. 13., the following one, told me by a friend, may be cited. In the neighbourhood of Harrowgate there is a large building called the Observatory, which affords from its summit an extensive view. A pair of owlets, taken from a nest in an adjoining wood, were placed in a cage on the summit of the tower, and for nearly six weeks the old birds came every evening to feed them there. They brought them, in addition to mice and pieces of flesh, frequently fishes. The river Nidd is three miles from the spot. Could they have procured the fishes thence ? — A, Bloxam. RtigbT/, Warwickshire, Jan. 1834. An Instance of the Baim OwVs seeking its Food at Mid-day in sunny Weather. — I have once seen a barn owl on wing at between the hours of twelve and one o'clock in the middle of the day. The sun was shining brightly at the time. The owl, as the sequel proved, was seeking food. After I had watched it for some minutes, I saw it descend, and light upon the side of a bank of an old watercourse, and remain there for the space of a minute. It appeared to me to be working hard ■with its talons during that time, as if removing something that impeded its immediate attack on its prey. At the ex- piration of that period its labour was crowned with reward, for it then took wing, bearing away in its talons a fine mouse. — A. D. April, 1833. The Food {Contents of the Pellets) of Owls. (V. IS. 727.) * I am aware that there are often exceptions to these (as I suppose) gene- ral habits ; for I have often seen hawks of different species skimming with great swiftness southwards over the downs and fields of these districts, generally during a fall of snow. On July 24. 1830, I met a small flight of water swallows (-ETirundo riparia), and, about ten minutes after, another, flying south over Bowden Muir, about seven o'clock in the afternoon. They were evidently on a journey ; besides, it was nearly two miles from the Tweed, which they were apparently leaving. Again : a friend has told me that while himself and a companion were returning home early from a party in Edinburgh, on a foggy morning, they heard a flock of wild geese passing close over the city. They were aware of this from the repeated calls of the geese to one another, which calls were probably necessary to prevent separation : but they likewise distinctly heard the sound of their wings, which the stillness of the streets of Edinburgh at such an hour made easily distinguishable. The winged travellers were passing north- ward, as their course was indicated by their calls dying away in the increas- ing distance. J Birds, 147 — A pellet, which T, about February, 1833, found in Bays- water meadows, on the flat top of a tree's truncated stem, left in a hedgerow as a huge post, contained the fur and bones of two field campagnols (Arvicola agrestis Flem,\ as I have learned by submitting the skull bones to the inspection of an excellent comparative anatomist. — J. D, The Carrion Crow. — Mr. Waterton's admirable history of the habits of this bird, and his able advocacy of its merits, in VI. 208. to 214., have given me, and must all who have read them, extreme pleasure. One vice, however, is charge- able on the crow, to which Mr. Waterton has not adverted. This bird has a strong predilection for the eyes of sheep. I speak from my own knowledge ; for I have really caught this bird in the very act and deed of plucking out the eyes of a lamb ere it had scarcely drawn the vital air; hence, in " lambing-time," particularly where sheep are kept upon wastes and commons, which is much the case in Yorkshire, you will be almost sure to see a carrion crow or two lurking among them. The bird, with much cunning, watches the movements of the sheep, and, if the shepherd should not be constantly on the alert, the flock will most likely suffer some loss. The ewe, when about to bring forth, is very restless, lying down and getting up, &c., almost at every minute. The cause of this uneasiness the crow appears to know full well; for, sometimes before the parturient process is half over, the luckless offspring is bereft of one or perhaps of both its eyes. The crow is a most expert operator in this busi- ness : the villanous deed is finished by his murderous bill in the twinkling of an eye. I have also known these ravenous birds to deprive sheep of their visual organs, when, from sickness or the infirmities of old age, or from being entangled with thorns and briars, they were incapable of resistance. The carrion crow does not, on leaving its nest, cover its eggs : Professor Rennie was therefore in error when he stated that it did. — Thomas Weatherill, M, i). Liverpool, Dec, 7. 1833. [ The Titmice (Pdrus major and ccerideus, and dter andpalustris may be added) mil sometimes feed on Walnuts while these are yet on the Tree ,• a fact on their habits additional to those already registered in III. 476., IV. 166., V. 489. 655, to 66S,'] They eat the walnuts, attacking and devouring them as they grow on the tree, and before they are ripe enough to quit the green out- side husk. A walnut tree on the premises here affords peculiar facilities to the operations of these little depredators : it bears nuts which are frequently more or less imperfect in their shells ; that is, the shells, instead of being composed throughout of a L 2 148 Short Communications : — hard woody substance, are partially defective towards the apex on each side, or consist of a soft texture easily pervious to the bills of the titmice. Here, at the soft or imperfect apex of the shell, these birds commence their attack, and peck out the kernel to the utmost depth that their bills will reach. I have frequently known the entire kernel completely scooped out by the titmice, before the nut was ripe enough to fall from the tree. On one large tree, with a good crop, scarcely a walnut remained that had not been attacked by these birds, and more or less eaten. I mention this circumstance merely as a fact in natural history ; not by any means with a view to blacken the character of the birds in question, a race which, I cannot help thinking, is already more persecuted than it deserves to be.* \_The RooJc, VI. 142. VII. 100.] — For a similar reason, and with no unfriendly feeling towards the rooks, I may state that they also have a relish for walnuts. I have seen them settle on the trees, several in a party, and, plucking off the nuts, fly away with them to a distance. Whether they swallow the walnuts whole, or, as I rather suspect, stock through the shell and extract the kernel, I cannot positively say. One autumn I was rather at a loss how to account for the number of walnuts, some in their green husks, and some without, which were to be seen strewed on the walks under the elm trees which the rooks occupy as their breeding-place in the spring. Recollecting that the rooks occasionally plun- dered the walnut trees, and also that a day seldom passed without their reconnoitring their spring quarters, I was led to * Mr. Blyth has contributed a paper " On the British Tits" to the Field Naturalises Magazine : it is published in the number for June, 1833, and occupies more than seven pages, vol. i. 262 — 269. Have the names " cole tit" and " cole mouse," which are ascribed to the Parus ater, been so applied in expression of the blackness of the head, throat, and under side of the neck of this species ? The synonymes, Parus atricapillus Brissouy La petite charbonniere Buffon, and Mesange petite charbonniere Temminck, seem to prove that they have ; and if they have, the prefix " cole" should of course be spelled " .coal," analogously with " coaly hood," one of the provincial names of the bullfinch (Pyrrhula vulgaris), — " The honours of whose ebon poll Are brighter than the sleekest mole ; (His bosom of the hue With which Aurora decks the skies, When piping winds shall soon arise To sweep up all the dew.") Cowper. " Cole goose," one of the provincial names of the " great black cormo- rant," is likewise, it is presumed, an erroneous spelling for coal goose. — J.D. Birds, lAf9 conclude that the stray walnuts were such as had been acci- dentally dropped by the birds in their attempt to extract the kernels from the shells. Whatever may be urged in pre- judice of the rooks, and, besides eating a few walnuts, they certainly do peck up and devour a portion of the newly sown corn, they ought to be regarded as useful and beneficial crea- tures to man, and by intelligent persons are generally allowed to be so, for the reasons so ably shown by T. G. in VI. 142. — TV, T, Bree. Allesley Rectory, June 12. 1833. The partiality of rooks for walnuts is such as to render it not unprofitable, in an orchard of walnut trees, to keep a boy as a scarecrow, or rather scarerook, to prevent their helping themselves to the walnuts too extensively. A rook, having plucked a walnut, will, in its wariness, usually fly off to a common, or any open place which may be not very distant, to eat it unmolested. Occasionally a rook is induced to abandon uninjured a walnut or other nut which it had borne off from the tree that had yielded it, and such nut may, and in some instances doubtless does, vegetate and produce a tree ; and hence, and from similar accidents with other birds, it is that birds form one of the classes enumerated by naturalists in their catalogue of Nature's agents in disseminating plants. (See V. 527. note *.) The springing of an oak tree from an acorn buried by " a raven" has been likened to Melan- choly burying Hope, '* which Providence still keeps alive," in eight lines of poetry published in Dr. Hodson's selection of poems called The Bouquet, 2 vols. 8vo. 1 792. The lines were copied off " a pane of glass at Kingsgate ;" and, although entitled " a fable," describe an incident very likely to have happened : the poet, perchance, mistaking a rook for a raven. — J. Z). Companies of Rool^s delight to assemble and build near human Residences. — Mr. Jennings and others entertain this idea; and the following fact tends to establish it. In the grounds of Mr. Hope, at Deepdene, there are some trees on which rooks used to build invariably before the mansion was de- stroyed. This house stood close by the trees. Mr. Hope added Chart Park to his own at Deepdene ; and, as he did not wish to keep both mansions, the old Chart House was pulled down. No rooks have built on the trees since, though the trees remain in precisely the same state. — W. Fowler, Dec, 17. 1834. Instances of Enmity evinced by the Rooh and the Magpie to the Kestrel Hawk. (p. 105.) — ^I'was much amused, the other day, in witnessing an engagement that took place, over a small grove, between a kestrel hawk, five magpies, and four rooks. My attention was called, when at some distance, by the loud cries L 3 150 Short Communications : — of war. The rooks attacked the kestrel in the air, hovering over and around him, and were sometimes in close contact with him ; and when he, as if to gain breath, alighted on any tree, up came the magpies^with their loud clang of war, and fiercely carried on the combat. Again the kestrel mounted into the air, which the rooks no sooner beheld than at him they went, apparently as fierce as ever, and so they and the magpies continued alternately attacking him for about a quar- ter of an hour ; when he drove the rooks off, and, after having another round or two with the magpies, he left them, and soared off into quieter regions. The sight was the more in- teresting to myself, from my having but just left a friend who had related to me a description of a similar engagement, which he had witnessed between a kestrel and three rooks; and about a week since another friend told me of an engagement which he had seen, but with only one magpie. Both occurred within a mile from the place at which I saw the action. — T. Ai/lesbury, Oct. 14. 1833. [In the Field Naturalist, ii. 74., a correspondent tells of a kestrel and a magpie, which a countryman had seen fighting on the ground. " He approached them; the hawk en- deavoured to escape, but the magpie held her so firmly by the leg, which he had grasped in his claw, that she could not escape, and both were taken with the hand."] Habits of the Jackdaw (VI. 394. 396. 516.), Anecdotes on a domesticated One, — Being informed that with the cleanliness and management of the parish workhouse at Kidderminster I should be much pleased, I accompanied a clerical friend to visit it; and was gratified on finding the information true. Noticing a jackdaw at large in the governess's parlour, mani- festing as much self-consequence as if the whole establish- ment were under its control, I was told that the bird had become domesticated there when young, and had ever since been quite a free agent about the premises and neighbouring fields, and that it was a privileged pet and favourite, notwith- standing its many peccadilloes of pilfering and stealing. I learned farther as follows : — After it had been some time an inmate, it having observed that " the copper-drawer," in which pence and halfpence for household disbursements are kept, engaged a particular portion of the governess's care, one day, no sooner was this drawer unlocked and left open, than the bird began to carry into it whatever rags and loose things it could find. At first they were thrown out ; when, fast as possible, the bird, apparently in displeasure, carried them in again. The governess, thinking it strange, submitted to the bird's humour, by leaving the drawer open, after securing Birds, 151 the coin by locking the room door. It was then the spring season of the year. In the course of a few days, she was surprised to find that " Jack " had laid two or three eggs, and went on laying until it had laid the usual number. The bird was thus, for the first time, discovered to be a female. Though, in her rambles abroad, she had met with a sweetheart, her old quarters of peace and plenty were preferred to all the privileges of precarious freedom. From whatever excursions she might choose to take during the day, she always returned home in proper roosting time at night. A caged Fieldfare, — In the same apartment, and, like Miss Jack, perfectly contented, was a caged fieldfare, singing sweetly, it being summer time, I was not a little pleased to see a winter bird so happy in a strange land ; but more sur- prised was I to know that it is a bird of song. In its wild state, during its hybernal visit, we have only one or two notes, and those somewhat discordant, uttered as a call to its com- panions ; but the notes of this feathered stranger resembled the woodlark*s, subdued and warbling. It was originally brought to the kind-hearted governess, as a pensioner, with a gunshot wound. She doctored and recovered it ; and the bird, like its jetty friend Jenny Daw, is quite satisfied with its " settlement." — L, Booker, LL.D, Dudley, Jan. 7. 1834. : A Ferruginous Duck or Ruddy Goose {A^nas rutila, Fauna Suecica) was shot, a few days since, at Iken, near Orford [on the coast of Suffolk]. It is in the possession of Mr. Manning, chemist, Woodbridge. {Ipswich Journal, Jan, 11 , 1834.) — TV, B, C, [See VI. 141.] The Account of the Oyster- catcher (VI. 151-2.) reminded me of a circumstance relating to that bird which was entered in my notes during a visit at Ramsgate in 1830, and which is an additional proof of its capability of swimming and diving. On November 12., in that year, being out shooting with a friend, we beat round Pegwell Bay, crossed the Sandwich Haven in a ferry-boat, and proceeded along the shore till opposite the blockade station-house beyond Shellness, when an oyster-catcher flew past, which I shot at, and winged. It fell in the water, and swam boldly. The shore was flat and sandy, the sea calm and shallow, and the tide gently ebbing. Having no dog with us, my friend, anxious to secure the bird, actually undressed, and took the water after it, as it was making out to sea ; on coming up, he pooped to catch it, but it eluded his grasp by diving, and was lost to view till it emerged at a distance of several yards from him. He re- peated the attempt two or three times, but with no better L 4 152 Short Communications : — success. He then returned to the water's edge, shivering with cold. Nothing daunted, however, he took my double gun, and proceeded to the charge a second time. He fired, but with little effect; as, on trying to take the bird up, it dived again, though it did not remain so long under water as before, owing, no doubt, to its wounds. When it rose again, he killed it. These birds I noticed in pairs, and in little parties of four or six, all the autumn ; but as winter ap- proached, their numbers greatly increased. I have a spe- cimen, killed by myself on September 10., which possesses the white mark under the chin. — T. G. Chipping Norton, Oxfordshire, March 6. 1833. The Peqfo'wl (Pdvo cristdtus L.) is the natural Enemy of the Serpent Tribe, (VI. 515.) — An opinion to this amount prevails, as I have stated in VI. 515., in this part of England. I have now to communicate two facts which seem to fully justify it. The first has been related to me by an eye-witness of it ; the second is included in an extract from a letter sent to me by my esteemed friend, the Hon. and Rev. Charles Bathurst. — M. Chalmers, M, D. Hull, Dec. 12. 1833. A peacock was observed to remain for several days near to a hotbed frame in the garden at Raynell, and to make fre- quent attempts to break the glass of the frame with his beak, and, although he was repeatedly driven away from it, he as constantly returned to it again as soon as the gardener had left the spot. This circumstance at length attracted the atten- tion of the late Mr. Sykes (M. P. for Hull), who caused the frame to be removed, when the peacock instantly leaped into the bed, scratched away some part of the manure, under which he found a nest containing several young serpents, all of which he, with a little assistance, instantly killed and devoured. Extract from the Hon, and Rev. C, Bathursfs Letter to Dr. Chalmers; dated Siddington, near Cirencester-, Nov. 5. 1833. — " Lord Bathurst's park, &c., is two miles from this place, and in his woods, near the keeper's house, peacocks are kept as ornaments to the wild scenery, but not, as far as I have ever heard, or, even since reading your paper, been able to learn, for the purpose of destroying serpents. I do not make out that they are esteemed ' in this part of the country, the natural enemy of the serpent tribe ; ' neither do I see, in any of the works of natural history which I have consulted since reading your article, that this peculiarity has been noticed. Among ancient naturalists, Aristotle and Pliny say not a word on that subject; BufFon and Bewick, you say, do not mention this peculiarity, so I have not consulted them ; but I have looked into Goldsmith and Blumenbach, but find it not there Birds. 153 either. However, it may not be uninteresting to you, as in a great measure connected with your subject, to mention a cir- cumstance which recently came to my knowledge. My friend, Sir John Ogilvy, who has lately been staying with us, told me that, last year, when riding at Halnaker Park, in Sussex, he saw a pheasant with a long thin substance in its beak, and, upon his making towards the bird, he flew off and dropped his prey, which turned out to be a slowworm or blindworm (^"nguis fragilis). The pheasant has, by this anecdote, been proved to prey on serpents ; and, if it be true of the pheasant, why should it not be true of the peacock, for they are both species of the same order, Gallinae?" Some of the Habits and Anatomical Conditions of a Pair of hybrid Birds, obtained from the Union of a Male Pheasant "with Hens of the Bantam Fond; and an incidental Notice of a hybrid Dove, — Sir, I send you a ^^vf particulars relating to the habits of a handsome pair of hybrid birds lately pre- sented to the Cambridge Philosophical Society by my father, J. P. Henslow, Esq., who furnished me with these details from his personal observations. I shall also subjoin a few anatomical remarks upon them, which were forwarded to me by Mr. Leadbeater ; who stuffed the specimens for us, and who had sent the bodies, divested of their skins, to an ana- tomical friend for examination. I am. Sir, yours, &c. — J. aS. Henslow, Cambridge, April 8. 1833. J. P, Henslow^ s Account of their Habits, — After having been several years disappointed in obtaining hybrids from the pheasant and common fowl [adults], I procured a brace of young pheasants, a cock and hen. These were brought up with four young smooth-legged hen bantams of the same age, in an enclosure of about 30 ft. by 10 ft. 1 purposely confined them in this small space, to create familiarity,which was effected; and the hen pheasant, the succeeding summer, laid many eggs, about one dozen of which proved good ; the bantams also laid, and about eighteen of their eggs proved good. The hybrids produced from these eggs were thriving, when a thunder-storm destroyed one half, and a cat killed all the remainder, except the two now sent to the Society. These were reared, and they proved to be a cock and a hen. In the succeeding summer (1829), the hen showed inclination to sit; but as the cock did so likewise, which seemed to disturb her, I removed her to a separate shed ; and she took to a nest of eleven eggs, which I put for her in a corner ; but, from what cause I know not, none of these eggs were hatched. Pre- viously to the next summer (1830), I provided them a small enclosure ; and, when I perceived the same inclination to sit. 154 Short Communications : — I supplied them with straw and eleven bantam's eggs. The hen sat closely ; as also did the cock at times, which, I sus- pect, disturbed her. One chicken, however, was hatched, which they reared with most sedulous attention ; particularly the cock, who called and accompanied it for some time after the hen had apparently neglected it. I again put eggs to them in 1831, and they both sat; but none were hatched. The hen moulted badly, and drooped till January, 1832, when she died ; and I then had the cock killed. It is worthy of remark that these birds evinced at least as strong attach- ment to the chicken which they reared as the real parent would have done ; though they never showed any regard for each other, as most of the hybrids, however, that I have kept have done. When the chicken was about a month old, I entered their place ; when they both flew at me violently, the cock, especially, attempting to attack my face. Hybrid Dove, — In the same case with these hybrids is a hybrid dove, from between a cock turtle dove and a hen ringneck (the common West Indian cream-coloured species). This hybrid, which is a male, has associated for three years with a hen ringneck, which has laid many eggs, and regularly sat on them, and been duly relieved in this office by her hybrid mate, but without effect. Extract from the Anatomical Ttemarhs fonxiarded through Mr, Leadbeater, — " In the examination of the two hybrid birds which you were so kind as to send me, the following appearances were observed : — One of them, which proved to be a male, had the muscles of the body in a healthy, plump, full condition, with very little fat in the intervening cellular membrane. The muscles of the other, which was a female, were extremely emaciated, of an unhealthy character, and the cellular membrane loaded with fat. In the latter bird, two small bodies of a dark colour were observed on each side of the spine, in the situation of the ovarium : they were smooth, and of a uniform appearance externally, pos- sessing very few of the characters of the healthy ovarium. The two oviducts reached nearly the whole length of the lateral parts of the abdomen, that of the left side being the longest. On making a small opening into the right oviduct, and inflating it, this was found to terminate in a cut de sac by the side of the rectum ; the loose abdominal extremity being curved upon itself, having an aperture at the end, of the size of a bristle, which allowed mercury to pass through it. The abdominal extremity of the other oviduct was simi- lar ; and the anal also had^ most probably terminated, like them, in a blind pouch, but an opening had been accidentally Birds. 155 made into it : it was very clear that it did not open into the gut or cloaca. A small pyramidal cavity existed at the back part of the rectum, into which neither of the oviducts opened, although they passed close to the sides of the gut. The lower part of the rectum was not at all enlarged, i. e. into the form of a cloaca ; nor were there any openings into it except those of the m-eters. The testes of the male bird were small, white, and of a healthy appearance : a vas deferens was clearly to be seen running from them over the surface of each kid- ney. Into one vas deferens a mercurial tube was placed, and it allowed the quicksilver to pass readily. The margin of the anus, with some of the rectum, having been removed, the quicksilver escaped at the cut extremity of the duct, so that it was impossible to ascertain in what manner it terminated. Osseous fibres existed in the muscles and tendons of the legs of both birds." Habits of the Hoopoe (ITpupa 'E'pops L.), as observed near Bordeaux, — On the Bordeaux side of the Garonne, and near the city, are large spaces of marshy ground, intersected by broad ditches and creeks terminating in the river; where, from the advantage derived from the water, many poplars and willows are planted for the sake of the twigs, which are much used for tying vines. These trees being topped at about 1 0 ft. or 12 ft. from the ground, so as to induce them to sprout much, become very thick, and, in the course of a few years, gradually decaying at the centre, are attacked by numerous tribes of insects, particularly the jet ant (i^ormica fuliginosa). In these retired places, which are frequented only by a few cowherds and country people, the hoopoe, which is a very shy bird, may be frequently observed examin- ing the rotten wood, and feeding on the insects with which it abounds. The hoopoe flies low and seldom, unless when disturbed, its food being so abundant as to require little search ; it remains the whole year ; and breeds in a hollow willow, about the end of May, laying two eggs of a cinereous or ash colour. The young come out in June ; but I could not ascertain the exact time required for hatching. This bird is occasionally, though rarely, met with in England, generally late in the autumn ; and, I believe, has never been known to breed in England, though it probably does with some of our northern neighbours : and its occasional visits to us may be in the way of its autumnal migrations thence. — E, H, GreenJiow. Bordeaux, Oct. 23. 1833. [Instances of the occurrence of the hoopoe in Britain are registered in II. 395., IV. 163., V. 569., VI. 150. Sir Wm. Jardine, in his notes to V^hite's Selborne, states that the figure of the hoopoe, published in Selby's Ilhist. of Orn,, is 156 Short Communications : — from an individual " taken on the coast, near Bamborough Castle, Northumberland ; " and adds that " Col. Montagu mentions that a pair of hoopoes began a nest in Hampshire ; and Dr. Latham records that a young hoopoe was shot in the month of June. The species is abundantly met with in the south of Europe; it also occurs in Holland, Germany, Denmark, and Sweden. In the winter it retires to Asia and Africa, where it is also a permanent resident." Mr. Blyth has recorded, in the Field Natu?'alist for January, ii. 53., that in the summer of 1833 a pair of hoopoes frequented a garden in the neighbourhood of Tooting, Surrey. — J. Z).] The Fern Owl, its time of Migration. (V. 674.) — The fol- lowing is an extract from a letter from my brother (H. T. Clarke, VI. 9 4'.) to a relative, dated Kronstadt, 27th June, 1833, English style: — " Tell W that whilst we were in the North Sea" (the date must have been 9th or 10th June), *' two fern owls settled on the main-topmast-stay, the only instance I have ever heard of these birds settling on a vessel. I shot one ; its crop was empty, and it appeared quite ex- hausted : the other got away. If I were at home, I would tell Mr. Loudon about it : he can do as he likes. They were most likely on their way from Norway to Lincolnshire, as we were then about 120 miles abreast of that county." I have followed my directions in communicating the above, as it will satisfy a correspondent in V. 674. ; but I regret that the tra- veller should have so cruelly divorced the poor birds. — W. B. Clarke. Stanley Green, near Poole, Aug. 24. 1833. One of the Habitats of the Fern Owl, or Night Jar, is a plantation at Paradise, in Broad Clist, Devonshire, ten miles from Exeter, the property of Sir Thomas Acland. The clutter made by these birds during the night is occasionally heard at an almost incredible distance. I have this on the authority of a friend, the Rev. C. R. Roper, M.A., of Mount Radford, Exeter. — W. B. Clarke. Sept. 12. 1833.

By early in December, five eggs were laid; but some boys, who had discovered the nest, caused the birds to forsake it. The nest and eggs were removed on Dec. 20., when, of the eggs, two that were accidentally broken, showed a state of progress towards the formation of young. I have the three unbroken eggs. A nest of young redbreasts in winter would be rare indeed, but the past season has been extraordinarily mild. — T, G. Chipping Noiton, Oxfordshire^ December 26. 1833. Reptiles. — A Tortoise foreJcnows the relative Coldness of a coming Winter, and foreshows the Degree by the Depth to nsohich it buries itself in the Earth. — I have a tortoise; I was going to say an old tortoise, but I know nothing about his age. I have had him about nine years. He was given to me by an old gentleman, who had possessed him at least twenty years, and who had received him from another old gentleman who had possessed him for many years previously, but who gave him away because he used to eat young let- tuces. Neither this person nor the gentleman who gave him me knew any thing about his age ; so it is not probable that I should. Every winter, this tortoise buries himself in the earth ; and, knowing better than Mr. Squire or Moore's Almanack what sort of a winter we are going to have, the colder the winter is going to be, the deeper he goes. Well, Sir, last winter [1832] the top of his shell was only covered two inches. There were, if you recollect, only two nights that could be really called frosty ; and now his shell is only just level with the earth, the very top of it being visible through the turf. Argal, we shall have no frost at all. — E. N. D. Dec. 14. 1833. This foretelling arrived too late for publication in the Number for January, 1834. E. N. D. has, on February 2., informed us that " the tortoise, on January 17. 1834, emerged from his hiding-place, and walked about as in summer." A Tortoise inhabits the Aquarium of the Botanic Garden at Cambridge ; and as this {it is possible) may eventually be- come as venerable as the tortoise above, and, like it, the hero of a tale, a timely registration of some facts in the history of its younger days may avail its future biographer. This tortoise was once my father's, who has, at my request, sup- plied most of the following facts respecting it. — J. D. The tortoise was given me in the end of May, 1828, by your aunt, L. Cross, to whom it had been given by her son, E. Cross, who had brought it, with five other tortoises, from 158 Short Commiinicaticnis : — the coast of Malaga in Spain, where he picked them up off the sands. Your aunt must have received it in the autumn of 1826 or ]827, because she says that during the winter it used to get under the grate. She used to put water or milk, with soaked bread, in a plate for it ; but it is not certain that she ever saw it take any thing. When I had received it, I, not knowing better, treated it as a land tortoise. I put it, in the day time, into the front garden (which is, from its aspect, the warmer one), but, contrary to my expectation, I could not perceive it take any vegetable food. I afterwards put it in the back yard, whence it several times made its escape ; and one day we considered we had lost it, until our dog traced it to the pond in the yard, and assisted in the capture of it. We then bored a hole in its shell, tied thereto a string, and to the same string, at about a yard from the shell, fastened a float, that we might capture the creature at any time. We regu- larly, in an evening, brought it in-doors and put it in a basket. When liberated, in the morning, it directly sought the pond : so that, after we had half-starved it, it had found its element. It was in the water that we first saw him feed on some small pieces of lights which your mother threw into the pond for it. Afterwards it became so familiar as to eat out of your mother^s and sister's hands (it seemed to show an aver- sion from men), and by its more healthy appearance, the quickness of its motions [and it would, when obstructed in front, travel backwards almost as fast as forwards], and by its getting frequently out of the water upon a stone at the pond's edge, to bask there in the heat of the sun, showed that it enjoyed its existence. When winter approached, it was less anxious to leave its basket. We then wrapped it up, and placed it in its basket, in a warm situation, until the spring. After keeping it through a part of the summer [of 1829], I made a present of it to Mr. Arthur Biggs, the curator of the Cambridge Botanic Garden, and took off its float, and put it into the sheet of water [supplied by a slow stream that passes through it], in which the aquatic plants are cultivated. Here it gets its own living, and has remained, to the best of Mr. Biggs's, and Mr. Scott the foreman's, knowledge, during four winters. [The length of time which it remains wholly unapparent (wherever it may hide) is not many weeks. Its first appearance, in 1833, was on April 2.] In warm weather, in the heat of the day, it either enjoys itself by sunning itself on a stone step at one end of the water, or on the grass at the edge of the water, or, when the water is low, on the narrow beach which intervenes the water and the grass. From this place it, on the approach of any one, hastens into Fishes^ Molluscous Animals, 159 the water, and has convenient hiding-places amongst the aquatic plants, and especially amongst and under the ample leaves of the water lilies (iVymphge a alba L, and 2S/'ilphar advena H, K.), and occasionally it floats stationary on the sur- face of the water, as it were in the manner in which fishes, in slow streams, are, in hot sunny weather, said to sleep. It has increased in size considerably, arta appears very healthy. Mr. Scott has told me, that once [in April or May, 1832] it travelled to near the Free School Lane entrance to the garden; a distance of, perhaps, 150 yards from the water, — possibly in search of a mate. These facts prove that this species of tortoise will live in any reservoir of water, like that in the Cambridge Botanic Garden ; and they may, especially if the amount of them is not already well known, promote endeavours to naturalise many individuals of this and other species of aquatic tortoises in similar situations, where they could not fail to be interesting objects to lovers of nature. — X D, sen. A young hand ToHoise.^ once kept in a cool green-house in a private garden at Bury St. Edmunds, lost its life by attempting to ascend a tall stone step placed at the threshold inside the entrance door. It fell backwards ; and the con- vexity of its shell was such, or the animal's weakness (for I suspect that it had been but very negligently fed) was such, that it could not apply its feet to the floor to lever itself into its natural position. It was found lying on its back, dead, and with froth at its mouth. — J". Z).

A Portion of Pearly Matter found within a Shell of the Freshwater Muscle [A'nodon cygneus) ; and the Reason why it Was formed there, — In the hollow of one of the valves of a freshwater muscle (A^nodon cygneus), which I lately picked up by the side of one of the ponds in this neighbourhood, I found a large irregular-shaped apparently solid mass of pearly matter, rather more than 1 in. long, | in. broad, and full \ in. high. It struck me as being an awkward encum- brance for the animal, and I was puzzled, as neither dint nor SpideT'like Animals. 161 fracture was observable on the exterior of the shell, to ascer- tain the cause ; but, on breaking a small portion of the irre- gular mass, discovered it. The animal had, by some accident, got a large mass of mud between itself and the shell, and not having the power of dislodging the mud, and probably finding the roughness of it disagreeable to the smooth surface of its own body, had formed a coating of pearly matter entirely over it, and had thus sagaciously rendered it, though it must have been a great encumbrance, as little inconvenient to itself as possible. — Id. The Limneus elongdtus Turton, Helix octarifracti Montagu, a7id H. octona Pennant. — Would that some correspondent would clear up the difficulty which appears to hang over these ! The figure in Veunsini^s British Zoology is quite correct, according to many dozens of specimens which I have found on plants in a pool near Southampton, where even the youngest shells have the fractured apex. Will Mr. Kenyon, who (in his list of land and freshwater shells in II. 273.) men- tions it under the name of Lymnae^a leucostoma, oblige me by stating in what degree my drawing (fig. 32.) is like or unlike his shell? — W.

Individuals of a Species of Limnocharis Latr. have been found subsisting, in one of their States, as Parasites, upon the Body of Dytiscus margindlis L.] — In turning over the leaves of vol. i. of the Zoological Journal, my attention was attracted by some figures in the 4th plate, and, on referring to the descriptions I found, in page 122., " A Memoir on Achlysia, a new Genus of Trachean Arachnides, by M. J. V. Audouin." Some years back, I carefully examined a specimen of i)ytiscus marginalis L., under the wings of which, and attached to its back, were above a dozen bags, each rather smaller than a grain of wheat, curved and narrowed at the end by which they were attached. On opening these sacs, I found, to my astonishment, that each contained a perfect animal, which I believe may be a Hydrachna, or rather Limnocharis Latr. As there is nothing new under the sun, I did not at the time regard this discovery, and lost my descriptions and drawings, which I now very much regret, as it renders my present communication very imperfect ; but, I hope, even this notice may be the means of calling the attention of some one to the subject better acquainted with the Trachearia than I am. Vol. VIL — No. 38. a 1 62 Short Communications : — • From the learned observations of M. Audouin on this class, it must have happened that the animals in the sacs which he examined, and has called Achlysia, were in an early stage of growth ; so that he had no opportunity of ascertaining what I, under more favourable circumstances, discovered. Whether the metamorphoses of the Hydrachnadae be known, I am not aware; but it will be very remarkable should they be parasitic in their different states; and it struck me, at first, as an extraordinary fact, that these animals should remain in their sacs attached to the Z)ytiscus by their rostrum, when they are matured, and have eight per- fect legs for use. I believe the Limnochares are not uncom- mon in ponds and ditches, and are supposed to feed upon animalcula, &c. De Geer mentions, I believe, that the eggs of a Hydrachna are attached to, and receive nourishment from, oneof the water fleas {Gyvmus Lin,). — J. Curtis. 57. Upper Charlotte Street, Fitzroy Square, Nov. 16. 1833. [To Achlysia Z)ytisci Aud. the text and figures in Zool. Journ, ascribe only six legs.] Chelifer cancrbides. (V. 754.) — I have often taken this odd little creature, and other species of Chelifer, attached to the legs of Musca domestica, M. meteorica, and M. larva- rum. I have observed them attached to flies, most frequently in hot weather ; but they are to be found, at almost any time, under the bark of trees, under stones, and amongst moss in dryish banks. The C. ^:ancroides is known to live in old drawers and closets, and amongst old books. It is undoubt- edly, at times, a parasitical creature ; but not generally. They attach to the legs of flies by one of their curious pin- cers ; but I have never seen them so attached as to lead me to believe that they derived nourishment from the flies. They feed, no doubt, in their usual habitats, on minute insects. — W. B. B. W. Nov. 14. 1832. Chelifer cancroides. (V. 754.) — A fly (Musca domestica) was yesterday produced to me, to one of whose legs were affixed four specimens of Chelifer rancroides. If this new instance can be called accidental, I am at a loss to conceive how so many enemies (as they doubtless are to its tribe) had attached themselves to one limb ? If the fly had acci- dentally placed the limb in a nest of these insects, it seems na- tural to believe that it would have had sufficient sensibility to withdraw it ere the whole family had time to attach themselves. At present, the most probable reason which can be advanced is, that the fly was asleep at the time. I have to regret that a tender-hearted and fearful boy in the room should have stopped all further investigation on this interesting instance.

Geology. — Additional Information on the Fucbldes allegha- nimsis. (p. 27.) — Nov. 11, 12. 1833. Two days' examination along the slope of the Shade Mountain, in Juniata Valley, has materially enlarged my knowledge of the geological position of this fossil. On the banks of the Pennsylvania canal, near Lewis- town*, the strata consist of numerous seams from 1 in. to H ft* thick, of argillaceous sandstone, more or less ferruginous, and varying in colour from dark brown to greenish blue. These are quarried in large slabs for the purposes of paving and building. The surfaces of these slabs are covered with i^uci in relief, whose forms are ill defined, and are smaller than the Fucoides alleghaniensis ; they are also separated by courses of soft argillaceous rock, from ^ in. to 1 in. in thickness, con- sisting almost entirely of similar i^uci. An opening, made into another part of the series, at a lower position, and at the distance of half a mile, exhibited no fewer than a hundred suc- cessive courses of these vegetable deposits upon similar rock, within a section of only 20 ft. perpendicular. All these fossil beds comprise the same undefined Fucoides, occasionally tra- versed by the larger species. I traced a succession of these beds to upwards of 200 ft. elevation. At the height of full 350 ft., the Fucoides alleghaniensis prevailed in abundance upon slabs of brown red sandstone, and probably extended 50 ft* higher. The whole series, therefore, which contains fossil Fuel occupies a thickness of from 250 ft. to 400 ft. Nov. 21. 1833. In traversing the parallel ridges called the Seven Mountains, at the distance of 15 miles west of the Shade Mountain just noticed, the Fucoides alleghaniensis appears on the surface of white sandstone strata, occupying a mile in breadth, and rising to the height of 1000 ft. Dec. 6. 1833. In Murney Ridge, 50 miles north of the Shade Mountain, and running parallel with, and at the dis- tance of 15 miles east of, the Alleghany Mountains, I again observed splendid specimens of F. alleghaniensis. I notice these localities, the detail of which is only interest- ing to show that this remarkable fossil is repeated at various and distant parts of the transition series in this country. — R. (7.

MISCELLANEOUS INTELLIGENCE. Art. I. Retrospective Criticism, Remarks in Defence of [Mr. Audubon'] the Authoi' of the " \_Biography of the] Birds of America " [VII. 66.], hy the Rev. John Bachman, Charleston, South Carolina, — Although, from my profession and habits, I feel no disposition to enter into controversy, yet, having had opportunities which few others possess of becoming acquainted with the occupations and literary acquirements of Mr. Audubon, and being prompted, not alone by feelings of private friendship, but by a desire that full justice should be awarded him for those ex- penses, sacrifices, and privations which he has undergone, I take the liberty of stating what I know on this subject ; and I have reason to believe, from the characters of the writers who have doubted his veracity and the authenticity of his works, that, with the generosity of feeling so distinctive of those who are engaged in liberal and kindred pursuits, they will be gra- tified to assign him the meed of praise which he so undoubt- edly merits. It appears that exception has been taken to two publica- tions of Audubon's ; one on the habits of the rattlesnake, and the other on the habits of the turkey buzzard (Cathartes Aura). The latter publication is now lying before me ; the former I have not had an opportunity of seeing; but, from what I gather from some communications in [this] Journal, it appears that he ascribed to the rattlesnake some of the habits of the common black snake (Coluber constrictor Zm.), as ascending trees in search of game, feeding on squirrels, &c. He also mentioned the remarkable fact, of their living a considerable length of time in confinement without food. [Here follows, in the manuscript, an extract of some length from Featherstonehaugh's Monthly American Journal of Geo- logy and the Natural Sciences, Nov. 1831, p. 221. (the commu- nication to that work to which Mr. Audubon, jun., has, in our VI. 551., referred), and a variety of evidence from Dr. Cooper, Dr. Leitner, Dr. Randolph, and Mr. Hockley ; the amount of which is, that " at least five well-defined species of rattle- snake are now found in this extensive country;" that rattle- snakes, of one or other species, climb and have been seen on fences, and on trees, and on bushes, and that one has been Retrospective Criticism, 165 seen coiled up and at rest, in the fork of a tree, at about 8ft. from the ground; that " the rattlesnake sometimes takes to the water, and is found a considerable distance from the shore in salt water ;" that the rattlesnake, in its native woods, feeds on squirrels ; even, occasionally, on the largest American squirrel (5'ciurus t;ulpinus), rabbits (Zepus ameri- canus), and also rats (Arvicola floridana Ord^ and, from the wording of the manuscript, probably other species of rat) ; and that, with regard to the means by which rattlesnakes cap- ture these animals, it is possible that " rattlesnakes may yet be discovered to be nocturnal in their habits ; possessing a degree of activity at night which is not exhibited by day, unless hard pressed by hunger." As this communication is professedly in reply to Mr. Waterton, who has, in VII. 67., line 8. and 7. from the bottom, observed that *' nobody doubts that rattle- snakes swallow squirrels," it is needless to occupy space to confirm an assertion which Mr. Waterton has not disputed. The Rev. J. Bachman states that he had not seen a later number of this Magazine than the one for Sept. 1833. The MS. will be returned to the party through which it reached us, to be published elsewhere, entire, if our elision dissatisfies.] With regard to the experiments of Audubon on the powers of smelling, usually ascribed to the turkey buzzard (C. Aura) [VI. 84. 163.], I acknowledge that he has adopted views op- posed to the long established opinions of naturalists. But no one who will read his paper on the subject, containing a full detail of a number of experiments on the habits of this vulture, can deny that, if he intended to deceive the world, he cer- tainly chose a subject where detection was easy and certain. In our southern cities, these birds, with their kindred species Cathartes atratus, are so abundant in our streets and on our house-tops, as to have become a nuisance. It is but due to Mr. Audubon to state, that, in his frequent visits to this city, be has fearlessly invited investigation on this subject. During his absence, he has written to me on several occasions, urging me to make farther experiments. A number of engagements prevented me from devoting as much time to the subject as was necessary to investigate it in such a manner as to prove satisfactory to my mind, and I postponed it to a more leisure period. On the recent visit, however, of Mr. Audubon to this city, I consented to institute these enquiries ; in the pro- secution of which I was aided by the intelligence and expe- rience of such disinterested naturalists and men of science as could be obtained. On the 16th of December, I commenced a series of expe- riments on the habits of the vultures (C. Aura and C. atratus); M 3 166 Retrospective Criticistn. particularly as regards their powers of smell and sight, which were continued, with little intermission, till the 31st. Written invitations were sent to all the professors of the two medical colleges in this city, to the officers and some of the members of the Philosophical Society, and such other individuals as we believed might take an interest in the subject. Although Mr. Audubon was present during most of this time, and was wiUing to render any assistance required of him, yet he desired that we might make the experiments ourselves, that we might adopt any mode that the ingenuity or experience of others could suggest in arriving at the most correct conclu- sions. The manner in which these experiments were made, together with the result, I now proceed to detail. There were three points on which the veracity of Mr. Au- dubon had been assailed : first, whether the vulture is grega- rious ; secondly, whether he feeds on fresh as well as putrid flesh; thirdly, whether he is attracted to his food by the eye or the scent ? To these queries, not only in justice to the American ornithologist, but to aid the cause of natural science, our enquiries were directed. First, whether the vultures of this country are gregarious ? — That vultures, during the breeding season, and occasionally at other times, fly singly, is well known ; but such is also the case with all our birds that usually keep in flocks ; witness the wild pigeon (Columba migratoria) and the robin (Turdus migratbrius), and many of our water birds. But that our vultures are gregarious, in the true sense of the word, is a fact well established. In most cases, in the interior of our state, as well as in the environs of this city, considerable numbers are found in company, from three or four to forty or fifty. They hunt for their prey in company ; they feed together on the same carrion ; they per- form their gyrations in great numbers together, and they roost together. I have visited their roosting-places ; a sight well worth travelling many miles to observe. In some deep swamp, or occasionally in high ground, surrounded by a thicket of vines and thorny shrubs, usually composed of ^lizyphus volubilis, and several species of 6^milax and JKubus, the buzzards resort for years together to spend their nights. Here, on some dead tree, and frequently on several that may be standing near each other, they are crowded so close to- gether that one or two hundred may be counted on a tree, and frequently thirty or forty on a single branch. The ground and bushes, within a certain extent, are covered with the ex- crements ; which, by their acridity, htive destroyed the whole undergrowth of shrubs and plants and every blade of grass ; so that the surface presents an appearance of having received several thick coatings of whitewash. Retrospective Criticism, 167 Secondly, whether our vultures subsist on fresh as well as putrid food? — On this head it was unnecessary to make experiments ; it being a subject with which even the most casual observer amongst us is well acquainted. It is well known that the roof of our market-house is covered with these birds early every morning, waiting for any little scrap of fresh meat that may be thrown to them by the butchers. At our slaughter-houses, the offal is quickly devoured by our vultures, whilst it is yet warm from the recent death of the slaughtered animal. I have seen the Fultur Aura a hundred miles in the interior of this country, where he may be said to be altogether in a state of nature, regaling himself on the en- trails of a deer, which had been killed not an hour before. Two years ago, Mr. H. Ward, who is now in London, and who was in the employ of the Philosophical Society of this city, was in the habit of depositing, at the foot of my garden (in the suburbs of Charleston) the fresh carcasses of the birds he had skinned, and in the course of half an hour both species of vulture, particularly the Cath^rtes Aura, came and devoured the whole. Nay, we discovered that vultures fed on the bodies of those of their own species that had been thus exposed. A few days ago, a vulture that had been killed by some boys in the neighbourhood, and had fallen near the place where we were performing our experiments, attracted, on the following morning, the sight of a Cathartes Aura, which commenced pulling off its feathers and feeding upon it. This brought down two of the black vultures, who joined in the repast. In this instance, the former chased away the two latter to some distance; an unusual occurrence, as the black vulture is the stronger bird, and generally keeps off the other species. We had the dead bird covered with some rice chaff, where it still remains undiscovered by the vultures. Thirdly, whether is the vulture attracted to its food by the sense of smell or of sight ? — A number of experiments were tried, to satisfy us on this head, and all led to the same re- sult. A few of these I shall detail. 1. A dead hare (iepus timidus), a pheasant (Phasianus c61chicus),a kestrel (Falco TinnunculusZ/.), from a recent im- portation, together with a wheel barrowful of offal from the slaughter-pens, were deposited on the ground, in a retired situation at the foot of my garden. A frame was raised above it, at the distance of twelve inches from the earth. This was covered with brushwood, allowing the air to pass freely beneath it, so as to convey the effluvia far and wide; and although fifteen days have now gone by, and the flesh has become offensive, not a single vulture appears to have per- M 4 168 Eetrospectwe Criticism, ceived it, though hundreds have passed over it, and some very near it, in search of their daily food. Although the vultures did not discover this dainty mess, the dogs in the vicinity, who appeared to have better olfactory nerves, fre- quently visited the place, and gave us much trouble in the prosecution of our experiments. 2. I now suggested an experiment which would enable us to test the enquiry, whether the vulture could be^attracted to an object by the sight alone. A coarse painting on canvass was made, representing a sheep skinned and cut open. This proved very amusing. No sooner was this picture placed on the ground, than the vultures observed it, alighted near, walked over it, and some of them commenced tugging at the painting. They seemed much disappointed and surprised ; and, after having satisfied their curiosity, flew away. This experiment was repeated more than fifty times, with the same result. The painting was then placed within 10 ft. of the spot where our offal was deposited. They came, as before ; walked around it, but in no instance evinced the slightest symptom of their having scented the offal which was so near them. S. The most offensive portions of the offal were now placed on the earth ; these were covered over by a thin canvass cloth ; on this was strewed several small pieces of fresh beef. The vultures came, ate the flesh that was in sight, and, although they were standing upon a quantity beneath them, and though their bills were frequently within the one eighth of an inch of this putrid matter, they did not discover it. We made a small rent in the canvass, and they at once perceived the flesh, and began to devour it. We drove them away, replaced the canvass with an entire piece, and again they commenced eating the fresh pieces of flesh exhibited to their view, without disco- vering the hidden food they were treading upon. 4. The medical gentlemen who were present, now made a number of experiments, to attest the absurdity of a story, widely circulated in the United States through the news- papers, that the eye of a vulture, when perforated, and the sight extinguished, would, in a few moments, be restored, in consequence of his placing his head under his wing ; the down of which was said to restore the sight. The eyes were perforated : I need not add, that the bird became blind, and that it was beyond the power of the healing art to restore his lost sight. His life was, however, preserved by occasionally putting food in his mouth. In this situation, they placed him in a small out-house ; hung the flesh of the hare, that had now become offensive, within his reach ; nay, they frequently placed it within an inch of his nostrils ; but the bird gave no Retrospective Criticism, 169 evidence of any knowledge that his favourite food was so near him. This was repeated for several days in succession, with the same results. I did not consider this last experiment as conclusive as others did who witnessed it. The bird might not have been wholly free from the pain inflicted by the operation, nor might he have been so soon reconciled to the new situation into which he had been thrown by the loss of sight ; but, in connection with other experiments, it strengthened us in the opinions we had formed. After having resorted to the means detailed above, to satisfy myself of the accuracy of the statements of Audubon as regards the habits of the turkey buzzard, detailed in Jame- son's Journal [for October and December, 1826], I once more carefully read over his remarks on the subject ; and I now feel bound to declare that every statement contained in that communication is in accordance with my own experience, after a residence of twenty years in a country where the vul- tures are more abundant than any other birds. We were not aware that any other experiments could be made to enable us to arrive at more satisfactory results, and, as we feared, if continued, they might become offensive to the neighbours, we abandoned them. As my humble name can scarcely be known in Europe, I have thought proper to obtain the signatures of some of the gentlemen who aided me in, or witnessed, these experiments ; and I must also add that there was not an individual, among the crowd of persons who came to judge for themselves, who did not coincide with those who have given their names to this certificate. " We, the subscribers, having witnessed several of the experiments made on the habits of the vultures of Carolina (Cathartes Aura and Cathartes atratus), commonly called the turkey buzzard and carrion crow, feel assured that these species respectively are gregarious ; the individuals of each species associating and feeding together ; that they devour fresh as well as putrid food of any kind, and that they are guided to their food altogether through their sense of sight, and not that of smell.

Indeed, it is highly probable that facts elicited from the experiments of Audubon on our two species of vulture, strengthened by those insti- tuted on this occasion, may apply to all the rest of the genus. Without having had many opportunities of observiition, I am inclined to doubt the extraordinary powers of smell ascribed to the condor of the Andes (C. Gryphus), and it would be advisable to make farther experiments on the vultures of southern Europe and Africa. Perhaps it may yet be dis- covered that all the birds belonging to this genus are alto- gether indebted to the eye in their search after food. Indeed, I am of opinion, that, while to quadrupeds (particularly car- nivorous ones) the faculty of scent is their peculiar province, this organ is but imperfectly developed in birds. As it does, however, exist, although in an inferior degree, I am not dis- posed to deny to birds the power of smell altogether ; nor would I wish to advance the opinion that the vulture does not possess the faculty of smelling in the slightest degree, although it has not been discovered by our experiments. All that I contend for is, that he is not assisted by this faculty in pro- curing his food : that he cannot smell better, for instance, than hawks or owls, which, it is known, are indebted to their sight altogether in discovering their prey. If our vultures had to depend on their olfactory powers alone in procuring food, what would become of them in cold winters ; in Ken- tucky, for instance, where they remain all the year, and where the earth is bound up with frost for months at a time, and where, consequently, during that period, putrefaction does not take place : and, if they had to depend alone on tainted meat for food, how soon would the whole race (at least, in our temperate climates) die of hunger ? How easily error may be perpetuated, from age to age, we may learn from a thousand other visionary notions, which the more careful observations of recent travellers and naturalists have exploded. At this day, the belief is very general in this country, that, immediately after a deer (Cervus virginianus) has been killed, the vultures, at the distance of many miles, are seen coming in a direct line against the wind, scenting the slaughtered animal. This may be accounted for, with a little observation, upon rational principles. When a deer is killed, the entrails are immediately taken out : these, or per- haps the blood which covers the earth to some distance, are seen by some passing bird. He directly commences sailing around the neighbourhood ; he is observed by those at a dis- Retrospective Criticism, I7I tance ; the peauHar motions of his wings, well known to those of his own species, communicate to them the intelligence that something good for them is perceived. These, hastening to the place, give information to those who are still farther off; and, in the course of an hour, a very great number are guided to the spot. But it will scarcely be argued that this great concourse of vultures has been attracted by the effluvia of putrid flesh, since the animal has been killed but an hour before. I come now to notice the most important enquiry, and one which has been my principal inducement in taxing the pages of [this] Journal, and the patience of [its] readers, with this communication. Whether Audubon is the real author of the book called Ornithological Biography. Probably this ques- tion is already settled in Europe ; as his original manuscripts are there, to which many of his friends have had access. The September Number of this Magazine is the latest that has been received in this part of America : perhaps [the] subsequent Numbers may have shown that this voice from his native land was unnecessary to establish a fact already placed beyond the reach of suspicion. [The additional com- munications on the matter occur in VI. 550., VII. QQJ^ Be this as it may, I am unwilling that the lukewarmness or the confidence of his friends should deprive this enterprising ornithologist of the reputation which he has so laboriously acquired. No naturalist in this country has ever bestowed so much of his time, industry, and wealth, or made so many sacrifices to a favourite pursuit, as he has done. To this he has devoted the most active portion of his life ; to accomplish this, he has traversed the whole of this wide-extended country, from the Atlantic to the very foot of the Rocky Mountains ; from the swamps of Florida and Louisiana to the snows of Michigan and the rugged rocks of Labrador. For the last two years and a half, I have been intimately acquainted with Audubon : he has resided in my family for months in succession. From a similarity of disposition and pursuits, he was my companion in my rambles through the woods and fields, and the enlivener of my evening hours. During his absence, we were constant correspondents ; and his letters, amounting to nearly a hundred, are now lying before me. His journals have been regularly submitted to my inspection ; his notes and observations were made in my presence ; and a considerable portion of the second volume of his Ornithological Biography was written under my roof. I have carefully compared his first volume with the forth- coming one ; and, from all these opportunities which I have 172 Retrospective Criticism, enjoyed of making a decision, I do not hesitate to state that Audubon is the author of the book to which his name is attached ; and that the second volume will not fall short of the first in purity, vigour, and originality of style ; and that it will contain the additional experience and observation of three of the most active years of his life. Some details of the habits and pursuits of this gentleman may not be uninteresting to your readers, and will account for the manner in which he has been enabled successfully to carry on so large, expensive, and laborious a work as that which is now in the progress of publication. He rises with the earliest dawn, and devotes the whole of the day, in intense industry, to his favourite pursuit. The specimens from which he makes his drawings are all from nature ; carefully noting the colours of the eye, bill, and legs ; measuring, with great accuracy, every part of the bird. Where differences exist, either in the sexes or young, several figures are given on the same plate : sparing no labour in retouching old drawings or in making new ones, in all cases where he conceives there may be a possibility of making an improvement. In this way, he has already succeeded in figuring nearly the whole of the birds necessary to complete his splendid and important work. He keeps a journal, and regularly notes down every thing connected with natural history. This journal is always kept in English : a language which, it must be acknowledged, he writes very correctly, when it is taken into consideration that he spent nearly the first seventeen years of his life in France. Besides this, he keeps separate journals, in which he notes every thing that he learns each day on the habits of every bird. In all his travels, he carries these journals with him; and he never suffers business, fatigue, or pleasure to prevent him each evening from noting down every interesting observ- ation. In this way, a mass of information has been accu- mulated from year to year. When he sits down to write the history of a bird (which is usually in the evening), he first reads over all the memoranda which he has made with regard to its habits ; and he is generally able to write an inter- esting paper on the subject in the course of the evening. At some leisure moment this is again reviewed and corrected : the scientific details he leaves to the last. In America there are few private or public libraries that can furnish a writer on ornithology with all the information he is desirous of obtain- ing on this subject. Mr. Audubon does not hesitate about consulting with other naturalists in regard to all that may be written or known on the birds of America. He wishes to Retrospective Criticism, 173 render his work as perfect as the experience and knowledge of man, in the present state of his information, can make it ; and he endeavours to obtain all the additional light that industry or enquiry can shed on the subject. In obtaining this kind of assistance from those whose knowledge of books enables them to afford it, he does not conceive that he is the less entitled to the claim of the authorship of a work, the whole design of which (the most important feature in its execution), together with the composition, is altogether his own. When Wilson, the highly talented American ornithologist, first commenced his invaluable work, he did not hesitate to apply to his scientific friends for all the information they were able to afford him. In his letter to Bartram, dated May 21. 1804, found in the 36th page of his Life, by his friend and biographer Mr. Ord, we find Wilson using the following language : — "I send you a few more imitations of birds for your opinion, which I value beyond that of any body else. Please to send me the names of the birds." Now, although Wilson received all the aid which the observations and reading of his friend could afford him, yet it would be the height of injustice to his memory and his well-merited fame, to assert that Bartram was the author of his work. Let us be as just to Audubon as we are to his predecessor, and we shall not withhold from him the merit of being the author of his Ornithological Biography. If the idea is entertained abroad, that the character and acquirements of Mr. Audubon are not estimated in his native land, or that his splendid publication is not appreciated here, it is most certain that the impression is altogether erroneous. The United States, although comparatively a new country, and possessing but few men of very large fortunes, duly appreciate the value of his work, and the merits of the individual. Since his last return to America he has already received sixty-one subscribers to his work, with very little exertion on his part. It has been added to the library of Congress, and the legislatures of many of the states have become sub- scribers. The government has allowed him and his attend- ants the free use of all our public vessels in every part of the United States. Honours have been conferred on him by the learned societies of our land, and the attentions which have been bestowed upon him, by the most intelligent men in our country, are such as have never been conferred upon any former naturalist. The additions already made to American ornithology by 174 Retrospective Criticism^ the labours of Audubon are immense : suffice it to say, that he has added upwards of one hundred species not figured by Wilson. Some of these have been described in the valuable continuation of Wilson's work by Bonaparte. Still, with these deductions, there will be an immense number of new birds published in the work of Audubon, for a knowledge of which the public will be solely indebted to his zeal, industry, and experience. Amongst other interesting discoveries made by him may be noticed a new heron, and an eagle, the largest in the United States ; two species of pigeon, a humming- bird, and a considerable number of the genera of the Musci- capa, Troglodytes, Sylvia, and jPringilla, His services alone, in correcting the errors into which his predecessors had fallen, from the want of opportunities such as he has enjoyed, are invaluable, and will be duly appre- ciated by the lovers of natural history. It may be interesting to your readers to notice a few of these. In his recent visit to Labrador, to which inhospitable region he was led solely by his ardent zeal for the advancement of science, he has ascertained that the iarus marinus and the Zarus argenta- tmdes are the same bird in different stages of plumage. In the iarus minutus and L, capistratus, a similar mistake had occurred. The ^'rdea Peale/ of Bonaparte proves to be the young of the ^'rdea rufescens, as ascertained by Audubon in the highly interesting ornithological region of Florida; the figure of Wilson of the Rallus crepitans, given as the adult bird, proves to be that of a new species found in the fresh- water marshes of our southern country, and the Falco iagopus is only the immature bird of the Sancti Johannis. In addition to this, the visits of Audubon to the breeding- places of many other of our rare birds, in the extreme north and south of our country, have enabled him to investigate their habits more fully, and to describe them more correctly, than had ever been done before. If the enquiry be made, what prospect there will be of the continuation of this work, in case the author should not live to complete it, I am happy to say that its publication is secured beyond the fear of accidents. The drawings of the birds for the whole work are nearly completed ; the materials for their history are collected and recorded ; and there exists sufficient acquirement in the members of his interesting and talented family to carry on the work. Let the literary world but award to Audubon the justice which he merits ; let the public continue to be indulgent and hberal, and this work cannot fail to prove a very important acquisition to the natural history of America, nor to reflect the Retrospective Criticism, 175 highest credit on the liberality of the British public, that has hitherto so efficiently aided him in the publication of it, nor to establish an abiding monument to the fame of its author, whilst it must continue to be selected as the chosen companion of those who delight in the contemplation and investigation of the phenomena of nature, in one of the most interesting depart- ments of her works. — John Bachman, Charleston^ Dec. 31. 1833. [Received Feb. 7.] The Common Redwing is a resident Species i7i the extreme North of Scotland and in the Isles. (Mr. Blyth, in VI. 516.) — I should feel obliged to Mr. Blyth if he would state its locality, and whether he has had personal opportunities of examining it in its summer haunts, as, I believe, this bird has hitherto generally been looked upon in the light of a stranger, merely paying us a visit during the winter season. I can assure Mr. Blyth it is not a summer resident on the eastern coast of Scotland or in the Orkney Islands, although Dr. Barry says, in his History of the Orhiey Islands, book iii. p. 316., 2d edit., " it may be seen in Hoy for the most part of summer, and always in harvest; where it probably builds among the shrubs in the valleys." At least, I could not discover this bird, during an extensive excursion through these islands and a great part of the Highlands in the summer of 1831 ; my prin- cipal object being that of inspecting the habits and nidification of the different birds that resort thither. The only instance recorded of the redwing's breeding in the British Islands is in Montagu; who says, " Mr. Bullock found a nest in the Island of Harris in the Hebrides." The solitary instance here mentioned must invalidate the idea of those heard by W. L. (VI. 218.) being identical with the redwing, unless their locality is changed since Mr. Bullock's visit; or, otherwise, he must have found their nests in greater abundance than he appears to have done. I suspect that the young of the missel thrush (Zurdus vis- civorus) has very often been mistaken for the redwing, as they congregate towards the end of the summer. I saw, during the month of August, at least a hundred assembled to- gether, and at first thought they were a flock of fieldfares or redwings ; but, on a closer examination, I discovered my mis- take. They certainly must migrate. The fact of their mi- grating is mentioned in V. 581. Montagu says further of the redwing, " It is said to breed in Norway and Sweden." Bewick says only the latter countr3^ Mr. Hewitson, who visited Norway last summer, did not find it there, although he saw its congener, the fieldfare ( Turdus pilaris) ; and in his British Oology, Nos. xiv. and xv., says, " it 176 Retrospective Criticism, is the most abundant bird in Norway, and is generally diffused over that part which we visited, breeding (so contrary to the habits of other species of the genus Turdus with which we are acquainted) in society ; 200 nests or more being frequently within a very small space." Possibly some of the readers or correspondents of the Magazine, who may be personally acquainted with the Western Islands, will favour us with a more minute description of the nest, eggs, and general habits of the redwing. — J. D. Salmon, Stoke Ferry^ Norfolk, [See p. 144.] The Black Viper, (VI. 527., VII. 76.) — Mr. Bree's remarks (in VII. 76.) do not disincline me to repeat my former assertion, that I believe that there is but one species of poisonous reptile in England, namely, Fipera Bhrus.

It does not appear that either Mr. Stephens or Mr. Wood has figured the true Sesia stomoxyformis of Hiib. ; of which this (Jig, 33.) is a copy. It has two . orange lines on the thorax ; a band '^a^^Vw/V^rtia and four spots of the same colour on ^^^^^^^^^^^' the abdomen ; which agrees with Ste- ^^^^^^^^^ phens's Latin description, as well it ffi^ may, his being copied verbatim from 33 B Ochsenheimer, with the omission of " the word in parenthesis ; viz. " Alis (hyalinis) anticarum mar- ginibus fasciaque nigris; thoracis litieis duabus abdominis barbati cingulo punctisque later alihus fidvis ; palpis omnino nigris." But Mr. Stephens, in his English description, says, " thorax glossy, immaculate ; abdomen with fourth segment fulvous, orange, interrupted by a dusky black line beneath," &c. Whether this (Mr. Stephens's) is a good species, I will not pretend to say, as I have not had an opportunity o^ seeing a specimen. Catocdla elocdta, — Mr. Stephens lias remarked that " this fine insect presents a conspicuous instance of the baneful practice of mixing foreign and indigenous productions toge- ther ; particularly when undistinguished by any memorandum or label ; as, in consequence of an unticketed specimen having been detected in the collection of the late Mr. Blunt, this spe- cies has not only been selected and figured as a British ex- ample of the genus Catocala, but the error has also been subsequently copied into Loudon's Magazine [I. 272. fig. 136.]; whereas the specimen in question, which has thus improperly been introduced into our Fauna, was obtained Vol. y 11. — No. 38.

[StepJi, vol. iii. p. 132. n.) Mr. Stephens is, by this assertion, called upon to prove that Mr. Blunt's C. elocata came direct from Oporto; and I should be glad to be at the same time informed what the " some three or four other foreign species " were that " dis- figured his [Mr. Blunt's] cabinet. As to the foreign specimen of D. galii being there, that can easily be explained : — "It was sold hy Mr. Stephens to the late Mr. ^Xuntjhr a British insect : '* a baneful practice, which might mislead any one.

It was set like an English insect ; and formed, with two speci- mens of .Sphinjrligustri, the seventy-third lot at Mr. Stephens's sale o^ Bntish,\nsQcis in 1825; and, till it came into Mr.Curtis's possession, no notice was taken of its being a foreign spe- cimen.— J, C, Dale, Blandford^ Jan, 5. 1834-.

He will find a correct figure of it in Panzer (pi. 8. fig. 2.), as the male of ruficoUis. — J. a Dale, On the Nomenclature of the Thoracic Appendages of Insects, (VI. 495. notefj VII. 77, 78.) — Sir, I thank your corre- spondents, Lacon and Discipulus, for giving me an oppor- tunity of performing an act of justice towards Mr. Newman, You will recollect that the note (VI. 495. note f) to which these critics allude (VII. 77, 78.) was added in the hurry of correcting the press [It was added in the proof — J, D.'\\ and, at the moment, remembering that Mr. Haliday was the first English author who had employed the compound term metatarsus, but at the same time thinking he had made a more extensive application of these names, I considered that Mr. Newman had merely extended the idea, and that it would but be doing common justice to Mr. Haliday to mention the circumstance. Discipulus, however, overlooks (p. 78.) the fact, that, although the word thorax may be found in the lexicon, it also occupies a place in the Latin dictionary, and that in natural-history language, it is constantly used and declined as a Latin word : hence the terms medithorax and post- thorax are not so worthy of the mark of ridicule which a recent reviewer has thought proper to attach to them. More- over, my observation upon the barbarous compound nature of these names did not (notwithstanding your editorial paren- thesis to the contrary) apply to the designation of the thoracic Reh'ospective Criticism, 179 segments, but to the limbs attached to them. The remedy I proposed would have this result: medipedes and postpedes, medicoxae, postcoxae, medifemora, posttibiae, &c. (Latin compounds), would be introduced, instead of mesopedes, metapedes, mesofemora, &c, ; all of which are Greek and Latin compounds. Setting this objection aside, as well as that of the primary distribution of the thoracic segments, it is still undeniable, that this system of nomenclature, although attempted to be applied, is not applicable, as it ought to be, to all the thoracic appendages. If applied only to the legs and their various parts, it is good ; but, when applied to the wings, we have those organs which are attached not to the ^rothorax, but to the 7«^50thorax; termed proalse, not 7nesa\ae; whilst, on the other hand, were the system to be adhered to through- out, we should be under the necessity of terming the anterior or mesothoracic wings, middle wings, or mesalae. I shall only add that Mr. Lacon has again shown [in p. 77.] his critical abilities, by calling the metatarsus of Haliday the last, instead of the first or basal joint of the tarsus. I am, Sir, yours, &c. — J, O. Westwood, The Grove, Hammersmith, Jan. 14. 1834. The Persian Iris, the Odour of its Flowers, and the Idiosyn- a-asies therewith connected, (VI. 280.) — My brother-in-law, Mr. Mapleton, tells me he lately bought a root of the Persian iris, and asked the man, at the same time, whether it smelled sweet? " Sir," said he, " some people cannot smell it at all ; but, for my part, it knocks me down : I cannot bear it, it smells so strong." {_Ea:tract from a Letter from the JRexu W.T. Dree, Oct,l. 1833.] Cyathocrinite versus Encrinite, (78.) — As Mr. Conway has, in p. 78 to 80., accused me of error and misrepresentation, in stating that the pelvis and part of the costals of the cyatho- crinite, figured in VI. 561., have been covered by the column, I beg to assure him that it is nevertheless true ; and that, although he asserts it to be " a physical impossibility," yet it is a real fact, as several specimens in my cabinet distinctly 34, prove, one of which (a frag- ,^^.^^^,^;;s^^^ ment from the Derbyshire .-^rC^^^C^C-^^^J^l""' Scapula. limestone) is here figured.

T.Iark of tljc column. J80 Metrospective Criticism, Mark of the column. the annexed figure Miller, who says, in a note, p. 67. of his Crinoidea, " it is not unlikely that the real joints forming the pelvis are so much abbreviated as not to be visible ex- ternally.'* I also send a figure {Jig. 35.) taken from another specimen, in which the plates, which Mr. Conway seems to doubt the existence of, are better developed than in the specimen before mentioned. Mr. Conway asks, " Does it not always follow, as a matter of course, that, when the column is enlarged and expanded at its junction with the pelvis, the pelvis is also widened and enlarged in the same proportion, as in the genus Apiocrinites ?" and then says, " This, I think, cannot be denied." But, if he had examined the genus Platycrinites, in which the column occupies only a small portion of the centre of the pelvis, as in (taken of the natural size from one of my specimens), and compared it with the genus Apiocrinites, I feel confident that he would not have ha- zarded a speculation for which there is so little foundation ; and, in my opinion, there is much the same chance of suc- cess for his speculation re- specting the gradual change [transition by an intervening series of affinities] of En- crinltes into Cyathocrinites ; for though I have not seen the specimen in the Geological Transactions, yet in every specimen of Cyathocrinites that has come under my observation, the plates of the body are alike in number and position; and the superior parts, arms, hands, &c., are invariably divided by what Miller terms cuneiform joints ; whereas, in the Encrinites, the only plate which has this form in the scapula, and the only division which takes place above it is by a totally different process. A little further on, Mr. Conway states that it was because he considered his specimen a nondescript that he communi- cated it to this Magazine; but he most unaccountably forgets himself. He did not communicate it as a nondescript, but as the /% encrinite. He says (VI. ] 25.), — " I had my attention amply rewarded by being furnished with a specimen of the lily encrinite, of which 1 here send you a drawing, of the nMural size : " and at the conclusion (p. 128.), — " If I am right in supposing it to be the first discovered specimen of the lily a a.

Queries and Anders, 181 encrinite, I shall reckon myself singularly fortunate in having obtained possession of it;" tlie only doubt expressed in the letter being, whether it had been previously found in England or not. That it is not what he has there stated it to be, and what I particularly disputed, Mr. Conway himself now ad- mits, and the only difference which can yet be found betwixt his specimen and mine is, that the one is tuberculated and the other smooth ; but, when it is stated that I possess spe- cimens of the bodies, both plain and covered with tubercles of various sizes, yet exactly alike in every other respect, very few indeed will refuse to concede that they must rank together till some better distinction can be found, and it is much to be regretted that a name should have been given to any of them founded upon so very variable a character. Having freed myself from the charges brought against me, I beg to conclude with informing Mr. Conway, that it is pro- bable that his curiosity will be gratified, before the end of the year, by the publication of such of my specimens as are of sufficient interest to be inchided in Mr. Phillips's intended work on the Geology of the North and West Ridings of York- shire,— Wm, Gilbertso7U Preston^ Lancashire^ Jan, 20. 1834. Art. II. Queries and Anstvers* [Notice of a Species of Mouse, possibly an undescribed one^ ^which has abounded in Inverness-shire and Ross-shire.'] — In the May and June of 1832, over a great extent of moun- tainous district, including all the western divisions of Inver- ness-shire and Ross-shire (my enquiries have not extended into Argyle), the shepherds began to observe that their dogs were incessantly killing mice, which they naturally concluded to be what they usually call field mice. They observed that these mice increased as the summer advanced ; and that the grassy parts of the mountains were much destroyed by them, as they seemed, like the cut- worm, or larva of the 71pula graminea [ ? cornicina], to prefer the blanched part of the herbage, among the mosses and decayed matter of former years ; so that these grassy parts became brown. A curious and very interesting fact took place in consequence of, or rather accompanied, this great increase of these mice ; namely, the foxes, early in the summer, finding such a supply of food, which they appear to prefer to all others *, ceased from that time to destroy any more lambs. * I have long known that dogs (and, I think, the shepherd's beyond all others) are particularly fond of the Alpine mouse ; and, although I have repeatedly tried, in various quarters, to obtain specimens, it has been in vain, as the shepherds tell me that they only discover them by their dogs, who instantly swallow them. N 3 1 8? Qiierics and Ans^acers, But, some time in the spring of 1833, the mice were observed to have retired, like the lemmings of Norway ; and the foxes, in want of their accustomed food, again fell upon the sheep (the lambs at first) with unwonted fury. During the time that these mice were most abundant, the person who manages Mr. Frazer of Eskadale's sheep-farms, a man of rather superior acuteness and sagacity, paid some attention to them. He saj^s, that, as near as he could esti- mate, they devoured about 8 bolls (64 bushels) of his potatoes ; and that he dug out of one hole no less than seventeen of them, of various colours, probably young ones. He says that *' their general colour was brown, with a white ring about the neck ; and the tail likewise tipped with white ; a light- coloured stripe down the nose and along the back." As soon as I heard of this irruption of mice, I sent repeated requests for specimens, which, I suppose, was put off as a thing that could be " done any time ; " and now the mice have, it seems, departed from the land. If any correspondent would inform me if they have seen or heard of such a species of mouse, it would be very gratifying to me. I have seen two or three that I never could find any description or resemblance of in books. — W, L, Selkirhhire, Dec, 20. 1833. Has the Animal Le Lerot of Cuvier^s " Regne Animal" been observed in any English Orchard or Garden P With incidental Information on the Importation of Apples from Jersey and Guernsey to the West of England for manifacturing into Cider in the latter Place, — By a friend who has resided several years at Havre, I am informed that great destruction of the best fruit in the gardens takes place by the depredations of an animal about the size of a common rat, which eats the fruit as it becomes ripe. The name given to it by the in- habitants in that part of France is le rat mulot^ or the rat field-mouse. It resembles a squirrel more than a rat, the end of its tail being tufted. From the proximity of the northern coast of France to England, and the great import- ation of fruit in the autumn, it is rather remarkable that the animal has not been imported into this country. I do not recollect ever seeing any animals of this kind in France or Switzerland, but I understand they are very numerous. On referring to Le Regne Animal of Cuvier, I find, among Ics Rongeurs [Animalia rodentia, the gnawing animals], an animal named le lerot, which must be the animal provincially called 7'at mulot. It is described " as rather smaller than the rat, of a greyish brown colour above, and white beneath. The eye is surrounded with black hair, which extends and spreads to the shoulder. The tail, which is tufted only at the end, is black ; but the extremity is white. It is common in French Queries and Answers, 183 gardens, living in holes in walls, and doing much injury to the espaliers." Perhaps some correspondent can inform us whether the rat mnlot has ever been seen in English gardens or orchards, and can tell us something more respecting it than my meagre description does. On a late visit to Weymouth I noticed the large import- ation of apples from Jersey and Guernsey : waggon loads in sacks were frequently passing my apartments. On enquiry, I found they were sent inland to make cider. Can there be any other reason why the cider should not be made in Jersey and Guernsey, and imported from those islands, except the difficulty of importing all kinds of liquors, from the caution necessary to be observed in preventing smuggling of spirits and wine?-— JS. B, Nov. 26. 1833. Starlings and Rooks. — In the country, I have very fre- quently observed that immense flights of starlings attend on large flocks of rooks : when driven from one field, they fly to another, in company, though not mingled, but each forming a separate squadron. Does either species serve as a guide to any kind of food acceptable to both ? or for what purpose is this strange association ? — E. N. D. September, 1833. [Scolopax rusticola, in " Notes on the Starling, V. 284., has these remarks; — The starlings " are often seen in company with the rooks, and are in the habit of frequenting pastures with their larger companions. Their food, possibly, consists of the same species of worms, slugs, grubs, &c. They will often build under the rooks* nests in the rookery, and thus appear something like dependants."] Has any Correspondent heard the Song of the Water Ouzel f — My attention was attracted to it during a fishing excursion in North Wales, on October 8. 1833 ; and I should describe it as something similar to the faint warbling of the lesser petty- chaps, but continued a considerable time without cessation, as that of the stare [starling]. I was some time in ascertain- ing the fact, as the bird was sitting under a projecting bank ; and, consequently, the song appeared to come from the water. I never before had an opportunity of hearing it, which I attri- bute to the extreme shyness of the bird. — G. B. Oct. 18. 1833. [In I. 4?94., a correspondent has queried the name of a strange' bird whose characteristics he gives : one of these is, " its cry resembled that of the water ouzel."] Has a Geotrupes possessed of the Jblloxmng Characteristics- been previously described ? — Ater ; subtus aeneo-purpureus ; elytris punctato-striatis ; singulis macula ocellata aurantiaca prope apicem inferiorem. This insect has been captured by, ' and is now in the possession of, my friend J. Bannaii, Esq., N 4 181 Qiieries and Answers. of Plymouth ; in compliment to whom, I propose, if it has not been previously described, to apply to it the epithet Ban- nan/. The only distinction which I can find between it and G. stercorarius is the very striking appearance of two circular spots, one on each elytron, not far from the apex (tip), of a dull red or orange colour, with a black spot in the centre ; the whole exactly resembling, in form and size, the ocelli on the upper wings of Hipparchi« Janira^, or meadow brown butterfly, but differing in hue. It is of about 9 lines in length, and of a somewhat brownish black above, and bronzed with tints of copper and violet beneath. Mr. Bannan has taken, in this neighbourhood, two individuals perfectly alike. The specimen taken secondly has been accidentally destroyed ; but that taken first is in the highest preservation. Is it an unde- scribed species, or an undescribed variety only ? — W* A, Brornfield, Plymouth, July 15. 1832. Larvce of the Syrphidce, — It is stated in p. 283. oi Insect Transformations, that the maggots of this family attach them- selves to a leaf or a plant ; but in p. 5. it is asserted that they live in common sewers. Which of these two statements is the correct one ? I incline to believe in the latter. — J, H, F. [Both statements are correct. The larva of one of the Syrphidae is found attached to the leaves of the hop plant, and destroys, for its food, great numbers of the A^phis humuli, which, in some seasons, commits most serious injury to the health and welfare of this plant, and consequently to the crop of hops. All this is taught us by Rusticus of Godalming, in the Entomological Magazine, vol. i. p. 223., and the editor's footnote. Off a hop plant in our garden we, in 1 833, bred one or tw^o of this syrphideous fly; at least we suppose of the very same species : a competent entomologist has named our spe^ cimen, Syrphus balteatus. Of the larva or maggot of another of the Syrphidae, the Eristalis (Musca) tenax, it may safely be said, sewers, and the filthiest of places. Of this larva and its habits a pleasing de- scription will be found in Samouelle's Entomological Cabinet, No. ii. t. 3., where a figure of the fly, and of the cast skin of its pupa, are given. " In the larva state, when it is called ' the rat-tailed worm,' it breathes through a tail formed of re- tractile tubes, like a telescope, capable of being contracted or extended, according to the varying depth of the larva in the mud below." [Entomologia Edi7iensis, p. 35.) This fly is an interesting creature, in autumn, on the blos- soms of ivy, and the Compositae, as starvvorts, sunflowers, &c. ; and a hundred interesting facts on it, eligible for threading into a history of its habits, might be noted.] 185 REVIEWS.

Farther commendation we feel would be superfluous. Mr. Swainson has, with great judgment, abandoned the expensive and cum- brous plan of publishing in folio or quarto, and adopted that of royal 8vo. He is thus enabled to give plates at a lower price than has ever previously been done. The numbers are to be published quarterly ; and four of them, containing toge- ther fifty exquisitely drawn and beautifully coloured plates, are to constitute a volume, for which the price is 2/. 2s. The first series, of which No. I. is before us, is to contain the birds of Brazil ; and we are delighted to see Mr. Swainson thus erecting a monument to bear witness of his arduous and praiseworthy researches in that interesting and beautiful country. We are but stay-at-homes ; and we delight in that exquisite art which can thus bring the tropics in all their glo- rious panoply of charms palpably and visibly before us, with- out the slightest apprehension from the crushing folds of boa constrictors, or the savage and insatiable cruelty of jaguars. — JS.
