MEMOIRS, Sc. I—An Account of the Foramen centrale of the Retina, generally called the Foramen of Scmmering, as seen in the Eyes of certain Reptiles. ‘By Rozert Knox, M.D. M.W.S. Med. Ch. Soc. &e. (Read 15th November 1823.) W uen Dr SemmeErtine announced his discovery of a transparent point or foramen m the human retina, nearly, or, as some say, precisely in the axis of vision, it excited very strongly the attention of anatomists, and of the philo- sophic world generally. It was indeed a singular circum- stance, that so remarkable, and so easily detected, an ap- pearance should have escaped the observation of the dis- tinguished anatomists who preceded SammErine. The public attention having been much roused, numerous re- searches were immediately instituted by many English and foreign Anatomists, with the view of determining whether this perforation, or transparent portion of the retina, was VOL. VY. A 2 ACCOUNT OF THE FORAMEN CENTRALE peculiar to man, or was extended to other species of ver- tebral animals. The result of these inquiries, so far as I have been able to collect, is as follows. —‘ In Man,” (cbserves Baron Cuvier, Anat. Compar. t. 1. p. 422.), “ there is, near the entry of the nerve, and almost at the point which corresponds to the axis of the eye, a small fold of the retina, which forms a slight con- vexity, when the more external membranes are removed. In the midst of this fold there is a transparent point, which at first sight appears like a hole; the edges of this point are tinged with: yellow in adults, but not in the new-born infant. This peculiarity of the human eye, which had escaped. the observation of all anatomists before Semmer- RING, is found in no other animal, except in monkeys. We have observed it in the Cynocephalus,. in the White-nosed Guenon, &c. In the first, the transparent part is consider- ably larger than in man, and of an oval form: there 1s sometimes a yellow spot at its side. ‘The Maki, which of all Mammalia approaches nearest the monkeys, has only a slight fold, without any spot or transparent point. The other species have nothing simi- lar.” These facts, and others, relative to the pathology of this foramen in the human retina, were pointed out by many distinguished comparative anatomists.. The yellow spot or tinge, more or less surrounding the foramen, is said to be wanting when vision has been obstructed ; and the plait is small and wrinkled.. In monkeys, the yellow spot is occa- sionally absent. 'The important fact, that the appearances are limited to the eyes of man and a few quadrumanous animals, has been much dwelt on by physiologists, whilst the existence of a foramen, or transparent point of the membrane of the retina, situated in the actual line of vi- sion, has been deemed by most absolutely inexplicable. IN THE EYES OF CERTAIN REPTILES. 3 In a work just published by De BiatnviL_e, a distinet and direct allusion is made to a theory, partially supported by, nature, but which, in the present instance, is not appli- cable. It is there remarked *, that “ the differences which the Mammalia present, in the point of view we at present con- sider, are always susceptible of being divided into two categories; the one sort, pretty nearly inexplicable, is con- nected with what we have called the classical degradation, and with the degree of organisation to which the species belongs; the others are evidently in relation with the me- dium in which the animal must seek its food, or with the time of day during which it is so employed,—or, finally, perhaps with the nature and kind of its food.” ** T arrange (he continues) in the first category, the sort of yellow spot, with a small depression, more or less oval, translucid in the middle, around which the retina is some- what folded, which may be remarked in this membrane at some distance externally from the entrance of the optic nerve, in the axis itself of the globe of the eye. It is found only in the human species, and in the real apes of the Old and New Continent.” : Unfortunately for the ingenious theory just quoted, the transparent point of the retina or foramen, and the fold of the membrane, exist in a class of animals differmg widely from man, and from the apes of the Old and New Conti- nent: the class I allude to is Reptiles. I shall here briefly describe the appearances, and the particular species in which I have detected so singular an appearance. Professor JamEson having requested me to re-examine with great care my dissections of the class of Reptiles, and * Principes d’Anatom. Compar. p. 375. a2 # ACCOUNT OF THE FORAMEN CENTRALE having most kindly and liberally furnished me with the necessary specimens from the Museum, and, at the same time, pointed.out the works of the comparative anatomists of Germany, with whose labours he is intimately acquainted, I deemed it a favourable opportunity for completing my Inquiry into the organ of vision, and of adding to those observations which I had the honour lately to submit to the Royal Society of Edinburgh. It is not my intention here to enter into any details relative to the eye of Reptiles generally, but simply to describe the transparent point, or Joramen centrale, and fold of the retina, which I have found to be comparatively much more developed in these animals than in man himself. The animals in which these appearances were discovered by me were all of the Lizard tribe *, and the first in which I. remarked the presence of the transparent pomt, was the Lacerta superciliosa of naturalists. The notes taken during the dissection are as follow. Imo, The eye-ball comparatively large, resembling in external form that of the bird; the sclerotic horny and strong anteriorly, of a bluish colour, soft and elastic pos- teriorly. The retina very thick, somewhat firm and opaque. Where the optic nerve enters the interior of the eye-ball, there 1s a distinct marsupium, or black circular body, pro- ceeding forwards apparently through the centre of the vi- treous humour: this membrane, no doubt, incloses the bloodvessels distributed’ to the lens, hyaloid membrane, &c. 'Anteriorly, somewhat superiorly and towards the mesial line or plane, we perceive, on looking on the surface of the retina which regards the vitreous humour, a com- paratively large transparent, nearly circular spot, through * Tought to remark, that the most of these specimens had been pre- served for a great length of time im spirits. IN THE EYES OF CERTAIN REPTILES. 5 ‘which may be distinguished the dark-coloured . choroed. Close to this is generally placed a fold or reduplication of ‘the retina, which is in general ‘remarkably distinct. This fold..(or folds, for, occasionally, there are more than one), either proceeds from the transparent point towards the in- sertion of the optic nerve, or close to it. Sometimes the fold, seems, as it were, to lie over the transparent point, -and partly to conceal it from view; or the-point:is formed an the edge of the fold itself, asin apes; but, in general, _the fold runs directly from the insertion of the optic nerve upwards .and inwards, passing very close to the edge of -the foramen centrale. It will readily be imagined, that the farther dissection of this part of the-retina was attended with much difficulty, on account of the smallness of the eye- -ball. On the inner surface of the retina, and covering even the transparent point, is an excessively delicate vascular membrane, apparently supporting the branches of the cen- tral artery of the retina. When we remove the retina from the choroid, the former of these membranes, in some speci- mens, divides readily into two very distinct layers. The first, or that nearest the vitreous humour, is of an opaque- white, pulpy and thick; the second, or that situated next the choroid, is thin, of a slight bluish cast internally, pale brown externally, and cannot be detached en masse from the choroid, though sufficiently large flakes:may be forced off with the edge of the knife.. Near the Point of Soem- mering inwards, towards the insertion of the optic nerve, and around the. foramen centrale, these twomembranes are strongly connected with each other, and cannot be separa- .ted. When the whole of the membrane which we generally call retina is removed from the choroid, and drawn gently. towards the optic nerve, there is evidently a circular aper- ‘ure in the retina, constituting the foramen centrale,.and 6 ACCOUNT OF THE FORAMEN CENTRALE the choroid has at this point a slight projection in- wards *, I have stated that the fold of the retina is sometimes totally unconnected with the foramen centrale, but may be found occasionally proceeding from the point of insertion of the optic nerve outwards. When there are more than one, they resemble radii drawn from the centre of a circle towards its circumference. Sometimes a large deep fold proceeds from the optic nerve towards the edge of the transparent point, and from it outwards in a straight un- interrupted line. It would seem, therefore, that the forma- tion of these folds is accidental, in so far as regards their presence, or absence, or situation; but that they do not depend for their production, as has been supposed, on any mechanical disturbance of the internal parts of the eye-ball after death. Two specimens of the Lacerta superciliosa were e€X- amined, and one of the variety called Scutata: im all these the above anatomical appearances were remarkably dis- tinct ; and being comparatively larger than in man, did not require, in order to be perfectly seen, the aid of magnify- ing glasses. Three specimens of a small lizard, agreeing in descrip- tion with the Lacerta Calotes of naturalists, were examined. In these the eye-ball is somewhat less than in the super- ciliosa; but in all other points, as the distribution of the retina, the existence of the transparent point, deep and ex- tensive folds of the retina, &c., the animals entirely agree. In a very small specimen of the Lacerta striata, I ob- served the retina folded ina remarkable manner, and, by the aid of a strong glass, I thought I perceived a small “ There is in my possession a very beautiful preparation illustrative of “this. long disputed point. 8 IN THE EYES OF CERTAIN REPTILES. 7 ‘transparent point situated as usual, and close to the edge of this duplication of the retina: and, in a smail variegated lizard, with lobated feet, I observed the foramen or point very distinctly *. In the lizard called by naturalists the Gecko, the mar- ‘supium is very small, and the foramen centrale, or trans- ‘parent point, is wanting. Neither could I perceive it in the lizard called by naturalists Lanins (the Lacerta Ma- buya); in them also the marsupium is very small, though distinct. We thus discover that the foramen of SemmME- RING is found in a particular family of lizards, whilst it is wanting in others. Analogy would lead us to suspect its presence in the Chameleon, whose eye I have not yet had an opportunity of examining. It remains also to be dis- covered, whether the same anatomical distribution extends to the higher orders of lizards, as the Iguana, Tupinambis, and Crocodile t. There remains only a single additional fact which I wish to communicate in this notice; it regards the supposed ex- astence of vessels passing between the foramen:of ScemmE- RING and the vitreous humour. ‘With the view of deter- wining this point, I opened: the eye-ball in situ with the greatest care, and watched the removal of the humours from the retina; but however frequent the.examination, I ‘could never discover the smallest appearance of blood- aessels, lymphatics, or membranes, connecting at this point the retina and vitreous humour. * These lizards belong more strictly to the class of true or proper Lizards ‘than either:the Superceliosa or Calotes. + I have since ascertained that neither marsupium nor foramen centrale are present in the Crocodile. EDINBURGH, )} June 20. 1823. $ * a $ ON THE LESSER GUILLEMOT I1.— Observations on the Lesser ‘Guillemot and Black-billed Auk, the Colymbus Minor and the Alca Pica.of Linneus. By Laurence Epmonpston, Esq. | Corresponding Member of the Wernerian Natural ili Society. (Read 26th April 1823.) parr SSS THE practice of conferring specific distinctions on ani- mals essentially identical, has been, among systematic wri- ters, more general than that of confounding those which are distinct; and in the progress of extended and accurate observation, it becomes perhaps equally advantageous to retrench fictitious species as to discover new ones. | The system of Linnzus, long maintaining an influence so powerful and extended, and fixing on certain artificial, and often arbitrarily assumed, external characters, as legi- timate grounds of specific difference, contributed much to that excessive and fallacious multiplication of species of which we find so many instances in zoology. ‘This was ‘indeed a very natural result of that artificial system, which it was perhaps expedient and necessary for Linwzvs to AND BLACK-BILLED AUK. g select in the infancy of that science which his genius and industry so surprisingly advanced. Hence it happened that, in zoology, as in botany, the attention was perpe- tually in search of some one or two characters which, it was presumed, must necessarily distinguish each indivi- dual species. In birds, for instance, the colour of the plu- mage, especially of certain parts, as the tips of the pri- mary quill-feathers, the tints of the iris, of the bill, feet, er peculiarity of habits, without noting the causes of diver- _ sity, were each separately held to be immutable: specific distinctions. ; It seemed to be forgotten, that it is seldom by one dif- ference, but an assemblage of many, that nature marks specific distinctions; and had this been more frequently kept in view, we should have had less now to unlearn in some of the most interesting and apparently simple walks of natural history. | | ’ Burron and his followers adopted an opposite, but more erroneous, course,—preferring vivacity and eloquence of description to conciseness and accuracy of systematic ar- rangement; and their labours are conspicuous chiefly for the elegance of their style. | The modern French school seems peculiarly to have dis- tinguished itself by the variety of its divisions in the higher departments of classification; and a tendency to excessive refinement of nomenclature has perhaps been too frequent im their writings. Authors on classification have outstrip- ped the progress of observers on species, and, amidst the multiplicity of their subdivisions, seem sometimes to have lost sight of one of their chief objects—the discovery and accurate delineation of species. But it is still to this school, next to that of Linnzus, to which zoology owes most of its interest and-accuracy. The illustrious Cuvrer has en- nobled and exalted it to the rank in the scale of knowledge 10 ON THE LESSER GUILLEMOT which it has a right te occupy, and has unfolded its inti- mate connection with physiology and geology. Discussions that have for their object the enlargement and more accurate knowledge of such a science, will always be candidly appreciated by a mind truly philosophical, though they may be destitute of the parade of diagrams, or the mazy ingenuities of political arithmetic. The period is long past when flippant sneers at the patient and neces- sarily minute labours of the naturalist were received as wit ; it is now practically known that it is infinitely easier to ri- dicule than to reason; and that nothing is so contemptible as contempt from ignorance. Another frequent source of error in specific distinctions may obviously be found in the practice of determining spe- cies merely from the examination of stuffed specimens, with little of that previous and necessary preparation, alone to be derived from the frequent and continued habit of ob- serving animals in their living state, and ranging over their native haunts untrammelled by persecution or domestica- tion. It could hardly be expected that museums alone could confer that visws eruditus, so necessary and useful in discriminating animals from each other, as it is in other subjects of comparison. ‘There is a physiognomy that marks different species, as individuals of the same species are often easily distinguished, when we have frequent op- portunities of observing them, which, although difficult to be described, is yet strongly felt by the experienced, and which often affords the hint for the detection of more tan- gible grounds of difference. What is it chiefly but this that renders the rude fisherman or woodman often more accurate in specifically distinguishing his native animals than the systematic naturalist,—or which enables the shepherd to know each individual of his flock of many hundreds ?— differences in their aspect, which by others are inappreci- AND BLACK-BILLED AUK. Il able, are to him prompt and certain grounds of distinction. With what superior facilities to the northern naturalist would a native of the tropical regions enter on the descrip- tion of his indigenous animals, that, for example, of the numerous species of birds of paradise, of humming-birds, parrots, monkeys, insects? and the tropical zoologist would find a difficulty of a similar kind, though not so extensive, in describing our northern animals. To these causes are mainly to be ascribed much of the difficulty and error which we meet with in the study of zoology, as well as to the immense diversity of its objects ; and much requires yet to be supplied, even in one of its most interesting and apparently most accessible branches, Ornithology. Our knowledge of many species of European birds is still sufficiently defective; and from their bemg more frequent- ly presented to our observation, and naturally furnishing criterions of distinction for others, they especially require to be clearly known. In the notices of a few of those species that have occa- sionally been submitted to the attention of the Society, I have felt the influence of the preceding views, and have uniformly communicated only the result of my own obser- vations, in the first instance. When I found opinions of others on the same subjects, whether favourable or opposed to my own, I have freely examined them; but have not allowed myself to enter into discussions in regard to all the speculations that have been advanced, as these add but little to the value of ornitholo- gical investigation. I shall have the honour of continuing this series of ob- servations which I have commenced on several northern animals, regarding which obscure notions may still be en- tertained ; and those to which I shall confine my attention 1g ON THE LESSER GUILLEMOT at present, and which aptly illustrate the preceding views, are, the two supposed species of Lesser Guillemot and Black-billed Auk, the Colymbus Minor and Alca Pica of LINN&US. vr : It cannot but appear surprising that their claims to spe- cific distinction should not long since have been disposed of, and that there should be still naturalists who remain in doubt, or assert their distinction. I was induced to ap- ply particular attention in endeavouring to settle this ques- tion, not more from its involving the knowledge of the identity of two species, and opposing established opinions regarding them, than from my desire not hastily to deny the accuracy of the views of Monraeu, an ornitholo- gist of whose acuteness and industry I entertain so high an estimate; and I feel quite satisfied, that had his op- portunities of observation in this instance been more va- ried and. continued, his candour would have induced him to have relinquished opinions which he has so elaborately and ingeniously supported. Last summer, while in Zetland, I possessed opportuni- ties the most select for determing the weight to be at- tached to his opinions on these two species, and clearly convinced myself that what I had always believed regard- ing them was literally correct. I had also collected a re- gular uninterrupted series of specimens of the Razor-Bill and Foolish Guillemot, from the egg to the full-grown birds, erroneously described as distinct species. And the loss of the parcel, containing also other specimens of inte- rest, from the shipwreck of the vessel by which they were transmitted to this city for the inspection of the Society, I much regret, as it not cnly deprives me of many conclu- sive and satisfactory illustrations, but precludes that brevity which I am anxious to observe in discussions of this de- scription. AND BLACK-BILLED AUK. . 13 The opinion which I hold regarding the Colymbus Mi- nor and Alca Pica is, that they are merely the young, or the old in winter-plumage, of the two species Colymbus Troile and Alcea Torda, the Foolish Guillemot and Razor- Bill. Many ornithologists have maintained that they are separate species, but as Monracu has included all. that has been advanced for this opinion, I shall examine chiefly what he has stated on this subject. It has been imsisted on as a very strong circumstance in favour of the distinction of the two disputed species, that they are uniformly inferior in size and length of bill to those which are maintained to be their respective species in a state of maturity; but even if this difference of size were admitted, it could not be of any weight in specific distinc- tion :—it is very inconsiderable, and very varying, and can be observed only for a limited time; for, according to Montacu, we can have an opportunity of seeing these species of Lesser Guillemot and Black-billed Auk only during the winter months. Is it not very natural to anti- cipate that the young should not attain the full size of the parent birds for some time? Inferiority of size, therefore, should rather be a presumption against the opinion of their distinction. But, as far as my observations go, there is no uniform difference of size; they are fully as often to be met with equal in size as inferior; and even individuals of the C. Troile and A. Torda often materially differ in this respect. This irregularity may chiefly be attributed to in-. equality in their supplies of food, to which they must often be exposed in their earlier age, when the tendency to per-: manent size is impressed,—from the habit of prematurely committing themselves to a boisterous and capricious ele- ment, and, consequently, often being separated from the " protection of the parent birds. | 14 ON THE LESSER GUILLEMOT The bill is said to be longer in the Foolish Guillemot, and there is an indenture near the point in both mandibles, while, in the Lesser, there are only the rudiments of a slight indentation in the lower mandible. My experience proves that the bill of the Foolish Guillemot is shorter in the young, and gradually lengthens with age. 'This was the case with those I reared from a few days old till they were ready to fly, when they had acquired precisely the plumage of the Lesser Guillemot; but were still inferior even to it in size and length of bill. ‘The less numerous indentures in the bills, which are regarded by Montacu as peculiarly supporting his opinion, seem to me to lead to an opposite one. It 1s well known (as he himself admits) that the Razor-Bill, so analogous to the Foolish Guillemot m its changes of plumage and habits, has in its young state neither the size of bill, nor the numerous mdentations, which it has in the adult. It is surprising that this analogy aetld not have excited his suspicion. The white line extending from the bill to the eye in the Razor-Bill, and from the eye down the neck in the Foolish Guillemot, are conceived to be distinctive. In many specimens I examined, during last summer, these marks were absent; and in many specimens of the other two birds I have found them well defined ; and the Danish writer Mour *, in his Islandik Natur Historie, expressly mentions this as no ground of distinction. * In this author I find most of the opinions f entertained on northern sea-fowl fully confirmed. For instance, he distinctly states the Colymbus Immer to be the young of the Northern Diver ; and mentions not only its capability, but vigour of flight,—a fact which, being so long unaccountably overlooked, gave rise to so many fanciful and ridiculous conjectures to ac- count for its habits and incubation. It is singular that this book, which is one of the best topographical works in natural history, seems so little known. It was published at Copenhagen in the year 1786. AND BLACK-BILLED AUK. 15 The sulcz in the bill of the Alca Torda cannot be con- sidered as peculiar, for Monracu mentions a specimen of Black-billed Auk shot in February, in which the bill was as much furrowed as in the Razor Bill; and Fasricius also says, that all the young Alcze have the bill less sulca- ted and coloured than the adults; —*‘* hinc character de <¢ sulcis sumptus lubricus satis.” This I have myself repeatedly verified. It may be stri- kingly seen m what occurs in the Puffin: and indeed it seems surprising that ts young should not also have been described as a distinct species, equally as the young Razor- Bill. The black in the plumage of the Razor-Bill and Foolish Guillemot is less deep, and it extends over the whole head and neck; while, in the others, the throat and sides of the head are white, and the black parts of the plumage are of a deeper tint. Tis, which is stated as peculiar to the Lesser Guillemot and Black-billed Auk, is exactly the winter-plumage of the young of the others. ‘The old ones also assume the same appearance, still retaining the slight difference of a fainter shade of black on the upper part of the body. The specimen of young Guillemot, caught by Montacu in June, exhibits distinctly the young of the preceding autumn, passing into the plumage of the adult ; and. the winter-plumage of the Razor-Bill, as stated by Fasricius, is the same as that of the Black-billed Auk. The Little Auk is admitted to change its plumage in win- ter, to become white on the throat and sides of the head,— while these parts are black in summer. This is exactly such a change as its congenerous bird the Razor-Bill is asserted to undergo. If the Colymbus Troile and Alca Torda be distinct spe- cies from the others, and preserve their distinct appearance, how happens it that we never meet with them in winter ? 16 ON THE LESSER GUILLEMOT Though it were granted that they migrate, yet a few ought occasionally to be seen during winter. ‘The fact stated by Monrtacu, of a few Guillemots, m their usual plumage, being found in the end of January on the coast of Eng- land, is merely an instance of the old birds acquiring the summer-plumage sooner than the young ones; and, more- over, this is confessed by Montacv to be “ a single in- stance :” besides, if it were necessary, it might still be rea- sonably supposed, without receiving his conclusion from this fact, that these individuals had assumed their summer plumage earlier than is the general habit of the species; and this is an irregularity not unfrequent in other birds, and which may often result from their not having paired the preceding year; their moulting, and winter change may thus have been less complete; for I have certainly remarked, that incubation renders the moulting succeeding it more severe, and the change of plumage more marked. _ If the Colymbus Minor and Alca Pica be distinct spe- cies, Why are we not acquainted with their young ?—or, Are the young always the same in appearance as the old ? This is, however, contrary to the analogy of all water-fowl in our latitudes, and especially to that of the other species of this genera. _ The Black-billed Auks are said to occur more numerous- ly m Greenland than the Razor-Bill; but Fasricrus, whom Monracu quotes for this fact, expressly says, he never saw the Razor-Bills there durmg summer,—it applies to the winter season ; and the winter-plumage of the Razor- Bill, according to his description, is the same as that of the other. If then, as he admits, the suleze in the bill are no specific distinction—how could he distinguish these two species from each other? It is sufficiently suspicious that he should never have seen the Razor-Bills in summer, when they are comparatively numerous in winter; but it AND BLACK-BILLED AUK: 17 1s edsy to account for this, when he informs us, that the plumage of the Black-billed Auk in summer is just that of the Razor-Bill at the same season. It is farther remark- able, that while Fasricius gives minute details regarding the Razor-Bill in summer, a bird he declares he had never seen in Greenland during that season, he should say com- paratively so little of the Pica at the same season, a spe- cies he mentions having seen at all periods of the year. He also states, that the Razor-Bill lays two eggs; and every other naturalist, ncluding Montacu himself, mentions only one; and my observation agrees with this. And he asserts that the weight of the Black-billed Auk is superior to that of the Razor-Bill; yet he maintains the same opi- nion as Montacu, of the distinction of these two species. These remarks shew the contradictions imto which this author has been led; and that, though his authority is highly respectable in many other poimts of Arctic zoology, in this it must be received with limitation. If they be the same species, Monracu conceives they must moult four times a-year, since four different states of plumage may be remarked ; but this inference is not at all necessary. These different states are accounted for by sup- posing, what is the fact, and what is acknowledged to be so, that they moult partially twice a-year; and that the other changes of plumage are acquired, not by new feathers, but by the change of colour of the old ones. Of facts exem- plifying this change of colour in the old feathers, every practical naturalist has ample opportunities of satisfying himself; and for farther information on this point, I have only to refer to a very useful and interesting work, “ The * Philosophy of Zoology,” by a most intelligent and zealous naturalist, Dr Fiemine, whose opinion respecting these disputed species I am happy to find 1s the same as my own: VOL. Y. B 1s ON THE LESSER GUILLEMOT Monracu refers the disappearance from the British coasts during winter of the Razor-Bills and Foolish Guille- mots to migration ; but this is a cause that has been much too generally applied to account for the apparent absence of many species in certain countries; it thay be often ac- counted for by supposing them to change their plumage, or merely to disperse, when not induced by incubation to keep to certain haunts, and in numerous assemblages. Fapricius says, that the Razor-Bills and Black-billed Auks breed in Greenland, and are found there during the winter; but Montacvw states, that the Razor-Bills, not being so hardy as the others, migrate from the British coasts in winter, and their place is taken by the others. How, then, does it happen that the tribe of Razor-Bills in Greenland are so much superior in hardihood to their ef- feminate race on our coasts, and aré able to brave the ri- gours of the frozen regions, when so many of the Black- billed Auks even are compelled to quit them? Or, if some migrate southward, how comes it to pass that they are never seen on the British coasts? The Black-billed Auks are very far from being so numerous in Zetland as m Scot- land,—perhaps not much more frequent in that country than in England,—yet if such multitudes came from Are- tic countries, we ought occasionally to observe them there on their passage southward, as happens with other birds, which visit it as a half-way station. Not a single Lesser Guillemot or Black-billed Auk is seen on the coasts, even of Zetland, for six weeks after the alleged migration of the other species. This is decidedly opposed to all my observations. I have met with them from the period at which the Razor-Bills and Foolish Guillemots are first observed to quit the cliffs (im August), throughout the winter, till the middle of the ensuing spring. If they be not the same species, how shall we account AND BLACK-BILLED AUK. 19 for this circumstance, that they are uniformly found in Zetland a month or six weeks before any other Arctic birds make their appearance? Many of them are also then in a state of moulting, and incapable of flying; others have their osseous system almost cartilaginous,—their sexual or- gans imperfect, proving them to be young birds, and there- fore also equally incapable of flymg. All this could not have happened if they had had so distant and ey a migration to have effected. There are no Lesser Guillemots or Black-billed Auks to be found in Zetland in summer. Those met with in winter are regarded by the fishermen as the same species as the others. ‘Their habits are said to be different. It is men- tioned that the Lesser Guillemots and Black-billed Auks are found in great numbers on the coast of Scotland during the winter, while very few are found on the coast of Eng- land; and in neither country a single individual of the other two species is to be found, though vast numbers breed in England. ‘To migrate northward m winter is conceived to be unnatural and inconsistent, and, it is pre- sumed equally so, to suppose the young birds to be dif- ferent in their habits from the parent birds. If the old and young present the same plumage in winter, then there is no necessity for supposing that the former migrate; and the objection of distinction of habits does not exist: but, besides, difference of habits is not a specific mark in many instances; it of course constitutes an important feature in specific distinction ; but then it is permanent difference, not that of season or age, or insulated from other circumstances. Many birds of the same species are very different both in plumage and habits in the young and adult state, and many species modify thew habits according to locality. The Black-backed Gull, for instance, feeds on fish net carrion alone in some countries; in others, he mimics the Bg 20 ON THE LESSER GUILLEMOT Eagle, and treats himself to birds and young lambs! The Cormorant, in some situations, perches on trees, while, for the most part, he rests only on rocks by the water-side. The Hooded Crow, in maritime situations, forgets his characteristic timidity for the water, and skims along its surface like a Gull in pursuit of small sea animals, though, as I have sometimes witnessed, he occasionally suffers from his aquatic excursions. I believe one of the most charac- teristic marks of distinction of species of birds is to be found in their modes of flight ; it at least furnishes a good gene- ric distinction. And to those who are in the practice of observing the habits of birds, this difference of flight is very striking: no one is more aware of this than the expert sportsman, for much of his success depends on this know- ledge. The reason of these birds accumulating im Scotland in winter, and not in England, is quite apparent; the deep bays and friths of the former afford them food and shelter, which the exposed coasts of the latter cannot confer. It cannot be mere climate; for there is surely not so great a difference between the winter temperatures of these coun- tries, as in proportion to the greatly superior numbers that are found in Scotland at that period of the year. It is ac- cordingly in the Frith of Forth and the Moray Frith. in the east, and the corresponding lochs in the west, that they are chiefly found, while they are comparatively rare on the intermediate exposed coasts. ‘The supposition, therefore, that they should migrate northward to a short distance in the winter, is not in “ violation of the actual cause of the propensity to migrate.” | The Foolish Guillemot and Razor-Bill produce each one young. one in the year. The young, till about a week old, are covered by a dusky-grey down ; and the first co- lour of the feathers is that of the parent-bird. Previous AND BLACK-BILLED AUK. 91 to quitting the cliffs, about the middle of August, they have attained about one-half the size of the old ones: at this period the plumage is changed, the under part of the neck and sides of the head having become white. ‘This is the state of plumage in which they have been described as distinct species, and they preserve it during the winter. In December they have attained the size of the adult birds. To assure myself of their changes, I kept several indivi- duals tame till they were able to fly, and thus distinctly traced them. On the approach of spring, they may be seen passing into the summer-plumage of the mature birds. These also change in winter, turning white on the lower part of the neck and sides of the head; but, in the earlier part of this season, they may be distinguished from the young, by their greater size, and the less vivid black of the plumage. In the old Razor-Bill, also, the bill is larger, and more furrowed. In the adult Guillemot, the bill is considerably longer. As the season advances these distinc- tions become less apparent; but the old birds acquire their summer-plumage earlier in spring than the young. There appears, therefore, no reason for separating the Colymbus Minor and Alca Pica from the Foolish Guille- mot and Razor-Bill; and hence two species are expunged from the list. In the discussion which has led me to this result, I have been necessarily mute; but I have hardly been more so than the very ingenious and respectable or- nithologist from whom principally I have differed. The opinion I have supported is not a new one, but has been held by many naturalists, who have, however, chiefly con- tented themselves with its mere statement, without satisfy- ing their readers with an exposition of their reasons for it. This I conceived it to be useful to supply, especially as the advocate for the opposite opimion had displayed so much elaborate ingenuity in maintaining it. The discus- O29 ON THE LESSER GUILLEMOT ‘sion may also not be useless, in illustrating some of ‘those sources of error and precipitancy of observation, which have so much obstructed the advancement of zoology. If ‘species so much in our way have been so long erroneously known, it is not surprising that others less numerous and accessible should be also so. The great influence, too, of ‘Moyracu, in questions of British Ornithology, required that the few errors into which he had been unconsciously led by partial observation should be fully understood. The habits of the Razor-Bill and Guillemot are similar, ‘and very interesting ; they are gregarious, more or less, all the year round. ‘They occupy the same kind of cliffs du- ving the breeding-season, though the two species do ‘not indiscriminately mingle on the same rock. ‘They select long parallel ledges in the precipices about half-way from their summits, where they may be seen in large flocks, ‘sit- ting close together, and ranged above each other in regular rows; their white breasts, black heads, and erect forms, giving them a peculiar and orderly appearance. They live in the most cordial harmony with each other, ‘and display uncommon affection for their young. ‘These are taken to sea long before they seem capable of flying, and when their wings'can be employed chiefly in assisting their motions under water. The fishermen assert, that the -old birds carry them on their backs to the sea; but ‘this seems unnecessary. I have seen some quit the rock for the first tme; they were not one-third of the size of the adult ‘birds; and all that the wings seemed able to effect, was a kind of balancmg motion, to weaken their fall in the water. ‘When they reached it, they immediately dived, and, ‘al- though visiting it only for the first trme, swam well, ‘and kept long under it; and some even dexterously eluded, after the manner of their species, shots fired at them, by diving on the flash of the pan. The parent-birds were near, AND BLACK-BILLED AUK. 93 and anxiously endeavouring to allure them from our reach. After the old ones have brought the young to sea, they almost. immediately leave the land, and both young and old are then found in great numbers several miles off. The object of thus hurrying out to sea, seems to be to remove their young from their more numerous enemies, and to place themselves in comparative safety in commencing the process of moulting. 'This is very complete, or at least leaves them during part of its progress without the power of flight, the old feathers being generally cast before the new are sufficiently long for this purpose. The Velvet Ducks in North America are annually killed in great num- bers during the moulting process, when they are incapable of flying; and the Auks and Guillemots would experience similar havoc, if instinct did not teach them to withdraw from the reach of their more formidable pursuers. After an absence of two or three weeks, they again approach the coast, and are found occasionally in parties of three or four individuals. ‘The young are easily tamed, but I think rather difficult to rear. They display an unaccountable restlessness to- wards evening, incessantly moving about, and uttering a plaintive, piping sound. ‘They do not seem to be able to exist long in situations where they have not the opportunity of diving, and this, perhaps, is the reason of their going so early to sea. 'The fact, at.all events, seems certain, how- ever difficult it may be to assign a physiological reason for At. The thorax is very much elongated, and capable of great distension. _ The circulating system is much developed ; the heart and primary red vessels peculiarly capacious. The blood seems in greater quantity, and its colour is deeper than in Jand-birds,—-a fact I have remarked in most diving animals. The tenaciousness of life 1s very remark- 9A. ON THE LESSER GUILLEMOT able. ‘Two old Guillemots were confined in a cage for a fortnight, in endeavouring to domesticate them : during the whole time they obstinately refused all food; and when I released them to their native element, they seemed little changed, but in weight. One was a little weaker than the other; and it was interesting to observe the care and ten- derness with which it was regarded by its more vigorous companion: when it was unable to keep up with him, he would occasionally turn back, swimming round it, and ap- parently encouraging it by sounds and gestures to a beyond the reach of danger. ‘They are often observed to swim long after bemg shot through the heart: if the lungs, however, are wounded, they are unable to continue under water. The more speedy way of depriving them of sensation and life 1s by a sudden and violent concussion of the whole body. It seems almost impossible to tame the old birds; im- deed this is no unusual case, where birds naturally familiar in the wild state, or easy of domestication in the young, are incapable of it when in the old. From their breeding, for the most part, in situations of tolerably easy access, so much devastation is annually com- mitted by the fishermen among old birds, eggs, and young, that their number seems progressively diminishing; and it is to be regretted that the proprietors do not exert them- selves to limit this abuse. It is not as it was formerly in Zetland, and still is in some remote islands, when sea-fowl constituted a regular and necessary article of subsistence. The fishermen never trust to them for this use, and the most experienced and adventurous climbers are often the most indigent; besides, it is only the inhabitants of a few districts, that, from their vicinity to the haunts of sea-fowl, can practise their annual depredations, and they are ob- served to be certainly not more substantial than their AND BLACK-BILLED AUK. 95 neighbours. The practice encourages irregular, rapacious, and dangerous habits, for fatal accidents are not unfre- quently occurring to the fowlers: and checking its excess, would be repelling no romantic notions of liberty and at- tachment to country, associated with the chace, in minds alive to the refined pleasure of sublime scenery; for it is not the love of the chace, but its supposed subserviency to their emolument or taste, that induces them to pursue it. It has been observed, that, around grazing islands, and situations where sea-birds were formerly numerous, fish were also very abundant; and that the diminution of both keeps pace in some degree with each other, although fishing is not now more generally practised than before. Causes for this result it might not be difficult to assign. Besides, water-birds, by scattering migratory fish, as the herring, tend to render them more stationary and permanent in countries through which they might merely pass. Many of these species, also, in defence of their nests, prevent the more powerful rapacious birds from approach- ing near them, and thus are indirectly the protectors of the flocks that pasture in their vicinity. Proprietors seem not sufficiently aware of these advan- tages, or of the inexpressible interest and ornament which the feathered inhabitants throw over the rocky scene. EDINBURGH, March 24. 1823. 26 OBSERVATIONS ON THE ANATOMY OF IL.— Observations on the Anatomy of the Duck- billed Animal of New South Wales, the Orni- thorynchus paradoxus of Naturalists. By Rosert Knox, M.D. Member of the Wernerian Natural History Society, and. of the Medico-Chirurgical Society of Edinburgh. (Read 17th May 1823.) Menmorr I. On the Organs of Sense, and on the Anatomy of the Poison-Gland and Spur. Ir will not be expected that, after the numerous dissec- tions of the Ornithorynchus, performed in England, Ger- many, and France, by the most distinguished living ana- tomists, any very remarkable facts should have escaped notice. J am anxious that this should be borne in mind, for there are many who, viewing the Ornithorynchus as an excessively rare animal, might suppose every fact brought forward to be new, and censure the want of details, which could be useful only in the description of an animal hitherto altogether unknown. Now, this is far from being the case with the subject of the present memoir; for, at least one specimen has been anatomized in Germany, by Professor BLUMENBACH; one in Prussia, by M. Rupoirut; several THE ORNITHORYNCHUS PARADOXUS. 277 in France by the very celebrated author of the Lecons @ Anatomie comparée, and by others ; ‘and about ‘ten speci- mens, in the best state of preservation, in London. © Professor JAMESON, who did me the honour ‘to entrust ‘thedissection to me, encouraged me to proceed in carefully noting the details, because, though nothing novel should present itself, the investigation might still prove useful, by confirming the discoveries of others. We were also aware ‘that the descriptions of the most celebrated anatomists were ‘completely at variance with each other, and with those of naturalists, relative to the anatomy of some very important organs; and that, consequently, the physiology cf these organs must remain doubtful and conjectural, until the ‘cause of these differences should be satisfactorily explained. ‘have only farther to mention, that as it was necessary to respect the skeleton, which is intended for the Museum, I did not consider myself at liberty to attempt any very mi- nute dissections of the nerves, organs of sense, ligaments of the jomts, and soft parts situated in the bottom of the neck and upper part of the thorax, which were otherwise required to render the observations complete. It is well known that the specimens of this very extra- -ordinary animal first brought to Europe were considered by many as impositions. ‘They reached England by ves- sels which had navigated the Indian seas, a circumstance in itself sufficient to rouse the suspicions of the scientific naturalist, aware of the monstrous impostures which the artful Chinese had so frequently practised on European -adventurers; in short, the scientific felt inclined to class this _rare ‘production of ‘nature with easternmermaids and other works of art; but these conjectures were immediately dis- proved by an appeal to anatomy. _. As the animal became. better known, attempts were made by naturalits to arrange it with the Mammalia, to which 28 OBSERVATIONS ON THE ANATOMY OF grand division of the animal kingdom it evidently belonged; and, accordingly, in the Manuel of M. BLumensacu, we find it classed with the Beaver, Seal, Lamantin, &c. In the “ Regne Animal,” the Ornithorynchus is better ar- ranged with the Edentata, and is placed last. Two species are mentioned, one with reddish, smooth and slender hair, the Ornithorynchus paradoxus of BLUMENBACH ; the other characterised by dark-brown hair (6rwn-noiratre), flattened and crisped*. M. Cuvier conjectures that these may be but a variety from age; but I have observed, that all the dried specimens preserved in the Museum belong to the first species,—whilst the two animals lately imported, and of which I dissected one, belong decidedly to the second. These different species may be distinguished, not merely by the colour and texture of the hair, but also by the shape of the tail, which, in the latter, altogether resembles that of the beaver, as well in external appearance as in internal structure. \ The specimen dissected measured 16% inches from the end of the upper bill to the extremity of the tail; from the edge of the cloaca to the extremity of the tail measured about four inches. The Ornithorynchus and Echidna (an animal closely al- lied to the former) are oviparous +. As they have no mam- mz, they are without the grand characteristic mark of the first class of animated beings. Already naturalists begin to think, that animals differing so remarkably from the Mammalia, cannot with propriety be arranged with them. The skin being the part to which naturalists chiefly di- rect their attention, has been sufficiently well described. * Voyag. de Prnon, I. pl. xxxive The drawings of the Ornithorynchus in Pexon’s Works arc ill-executed, judging by the specimen now before me. + Homer, Phil. Trans. 3 THE ORNITHORYNCHUS PARADOXUS. 29 The palmated feet, and membrane extending beyond the toes of the anterior extremity ; the remarkable peculiarity of the bill, resembling so closely that of the duck, and to which an almost incredible number of nerves are distri- buted by all the great divisions of the fifth pair of cerebral nerves; the peculiarity of the hair, which is of two sorts, one sort fine and jointed, found on most parts of the body, but chiefly on the sides and abdomen,—the other bristly, flat, and shaped like the head of a spear, and which is found chiefly on the back and tail; all these facts, I be- lieve, have been already noticed. The beaver-like tail of the animal is covered with short hairs of the spear-pointed form; these more resemble bristles than hairs. The skin is thick and compact; and a powerful panniculus carnosus extends over the whole body, the feet, tail, and bill, being of course excepted. Some very distinct muscular slips arise from the panniculus carnosus ; the most remarkable are, Ist, The platysma myoides, or dermo-clavicular, ari- sing near the angle of the jaw, and proceeding downwards to be inserted into the aponeurosis covering the horizontal branch of the clavicle; 2d, The dermo-humeral, a strong muscular slip, arising from the panniculus carnosus, lying over the lower ribs, and following the course of the pec- toral muscles, is inserted into the os humeri, tendinous in common with the above muscles; 3d, The dermo-tibial, a strong slip, which joins the caudo-tibial, and has a common insertion with it; dastly, Two very strong muscular expan- sions, arising from the skin of the back, and loins, and con- verging like the radii of a circle towards its centre, are in- serted into the root and sides of the tail, and into the transverse processes of several caudal vertebrze: these are elevators of the tail, and may be called dermo-caudal. The action of the others does not require any particular motice. ‘These are the chief pecularities of the panniculus 30 OBSERVATIONS ON THE ANATOMY OF carnosus in the Ornithorynchus paradoxus: under the skin of the tail it degenerates mostly into a cellular tissue, in which is deposited a dark-yellow fatty matter. We may readily imagine the great powers possessed by this, the most extensive muscle of the body, over the viscera contained - within it; and how, being only a little increased in the Echidna, this latter should thereby be enabled to roll itself up into the form of a ball, after the manner of the common — hedge-hog. The skin and subcutaneous cellular tissue abounded so much with oil, as to render this part of the dissection un- pleasant; the cellular tissue betwixt the panniculus carno- sus and subjacent muscles was coarse, and in many places assumed the form of semitendinous fascia. The skin ex- tending beyond the toes of the anterior extremity contains within its substance five narrow longitudinal horny pro- cesses, resembling that which is found within the integu- ments of the upper mandible; the two innermost toes of the hind feet are likewise characterized by a process of the skin extending beyond the nails. I shall consider the bill of the Ornithorynchus as the organ of touch, by means of which the animal searches for its food; the supply of nerves is such as to render it the most perfect instrument of the kind with which we are acquainted. The length of the upper mandible, including the flap, is three inches nearly; that of the lower bill, and flap, only two. The organs of taste and smell will not detain us long : the latter organ, indeed, could not be properly examined, asI was not at liberty to injure the bones of the face ; it is pro- bably not very energetic. The nostrils open anteriorly near the point of the upper mandible; the anatomy of the pos- terior nares is regular, as in the Mammalia. The tongue has already been sufficiently well described by authors; it is covered with a thick cuticle, and cannot be considered 9 ~ THE ORNITHORYNCHUS PARADOXUS. 31 as possessing’ much sensibility; it seemed to me that the gustatory branch of the fifth was comparatively very small, but the hypoglossal nerves were large, and proportioned to the development of the strong muscles connected with, or entering into, the composition of the tongue. It is suffi- ciently curious, that the muscular apparatus supplying the tongue of the Ornithorynchus should much resemble that with which animals having a highly extensile tongue are furnished; yet, in the former, the lower surface of the tongue is so secured. as to render extensive motions of this organ impossible. The tongue is fleshy and thick: at about ;%;ths of an inch from its base, or 1,%,ths of an inch from its point, are inserted the lingual teeth, which, like the other teeth of the animal, are entirely cuticular, and may be removed by maceration along with the cuticle. I shall return to this subject when speaking of the organs subservient to digestion. The palate is marked by several transverse folds: deep notched indentations run along the sides of the lower bill, from its angle nearly to the point; those of the upper bill are found only near the angle of the mouth. These reduplications of the membrane of the bill might be supposed to increase the sentient surface; but it seemed to me that the nerves did not proceed to them in such abundance as to the anterior portions of the bill. I should consider, then, these folds as intended merely to al- low the mandibles to close very accurately, and thus to prevent the escape of those smaller insects on which pro- bably the animal feeds. — Though the actual organ of hearing did not come under my observation, still there presented themselves. several appearances relative to those appendages, placed between it and the external air, which merit the attention of the Society. There is no external ear, or rather there is no. ear externally ; for although there be no cartilaginous projec- 32 oBSERVATIONS ON THE ANATOMY OF tion exterior to the integuments, yet a tolerably perfect concha exists immediately beneath them. The longitudinal aperture by which the ear opens on the integuments is situated immediately behind the eye, and not far from the posterior or floating edge of the flap of the bill: The hairs are disposed around this aperture, as the feathers around the ear in birds. There is nothing peculiar in the aperture itself as to muscles, &c., but it opens immediately into a considerable cavity, formed by a cartilaginous plate, dis- posed after the manner of the concha of the Mammalia, and which we must consider as the true external ear of the animal, though it be not external to the integuments. The cartilaginous plate is fixed, on the one hand, to the long tube, connecting it with the cavity of the tympanum, and, on the other, in a very loose manner, to the superjacent integuments. Distinct muscles are attached to it, as in the Mammalia, which have the concha situated externally. These arise from the panniculus carnosus, and are inserted. into the concha: there can be little doubt, that, by their action, and the loose attachment of the cartilage of the ear to the integuments, considerable motions are performed by it,—the object of which must be to increase the general cavity formed by the concha, and cartilaginous tube of the ear, and in some measure to increase the size of the exter- nal aperture. Nearly one half of the external opening of the ear is formed by the edge of the cartilagmous tube; the common integuments form the remaining half, because the cartilage properly called Concha is thrown back under the integuments, having an extensive margin attached slightly by cellular tissue to the integuments, completing, in this way, the circle of the meatus externus. We thus see that there is a certain degree of inaccuracy in stating that the Ornithorynchus has no external ear; and that it should be said that it has no ear externally, since a tolerably THE ORNITHORYNCHUS PARADOXUS. 33 perfect external ear exists immediately beneath the integu- ments. It is extremely probable that a similar distribution of these parts may exist in some other animals described as being without external ears. We may now proceed from without inwards towards the internal ear, and briefly sum up the anatomy of the whole, as far as a respect for the skeleton permitted me to investi- gate. There is, first, the external opening, which had been mistaken for the simple termination of the cartilaginous tube of the ear, but which we have demonstrated to be the opening of the concha, that part of the cartilage which, in other animals, is in part detached from the head to form a true external ear, beg in this animal concealed by the in- teguments, but in such a way as not to impede its functions. I need hardly mention, that the concha was situated at the side of the opening farthest removed from the cranium. From the cartilage of the concha arises a remarkably long cartilaginous tube, proceeding from the upper part of the head, close to the eyes, over the lower jaw, as far as the base of the cranium; it measures in length 1,%ths of an inch, and nearly ;4,ths in breadth, when opened. The tex- ture of the middle tunic is not quite cartilaginous; it ter- minates at the root of the styloid process, and opens wide into the cavity of the tympanum. Near its termination in the tympanie cavity, a few projecting points, on its inner surface, mark the probable existence gf small cartilaginous bodies. The Eustachian tube is entirely cartilaginous, and is not inclosed in any osseous case; this is owing to a defi- ciency of a great part of the osseous circle constituting the frame of the membrana tympani. Now, in consequence of this deficiency, the anatomy of these parts is somewhat pe- culiar; for, in addition to the Eustachian tube being sim- ply cartilaginous, and not inclosed in any osseous case, (which, so far as I know, is peculiar to this animal), the VOL. V. c 34 OBSERVATIONS ON THE ANATOMY OF ossicula of the ear are much exposed, and the tympanic eavity has a great portion of its parietes composed of soft parts, or, in other words, is placed in a great measure ex- ternal to the cranium. The anterior part of the malleus is strongly attached to the extremities of the pterygoid pro- eesses of the sphenoid bone. ‘The stapes is composed of a single stalk and cireular plate, by which it is inserted into the vestibular foramen of the internal ear, the foramen being itself also circular. The form of the stapes appeared to me to be that in which the ear differed most from that of the Mammalia,. and even approached reptiles and birds; and had nature preserved the same form of stapes throughout the whole class of Mammalia, we might have noticed the stapes in the Ornithorynchus as a wonderful peculiarity. But this is not the case, for, in the Cetacea, the stapes dif- fers from all other mammiferous animals; it does not in- deed resemble that of the Ornithorynchus; but it is suffi- cient for our present purpose, that it differs essentially from that type which nature has so extensively observed. ‘* In- stead of the two branches,” observes Cuvisr, ‘° the Cetacea have a solid body, compressed conically, and perforated by only a very small foramen.” In the Ornithorynchus this perforation is wanting, (though it be present in some birds, as m the Owl); and the slender stalk and circular plate of the stapes bear the closest resemblance to the analogous ossiculum im birds and reptiles. Between the external os- siculum, or that connected with the membrana tympani, and which bears a close resemblance to the malleus in many of the Mammalia, and the stapes, there exists an ir- recular triangular-shaped bone, evidently analogous to the incus. Itis true, that this bone may, in the Ornithorynchus, be merely a process of the malleus; but I am by no means of this opmion, for the following reasons: Ist, It 1s most readily detached from the malleus; 2d/y, It has a consider- THE ORNITHORYNCHUS PARADOXUS. 35 able resemblance to the incus of the Mammalia, and has precisely the same situation; Jastly, The vertical direction i which it is placed, shows that it cannot be a process of the malleus. In thus reducing the ossicula of the ear to an analogy with those of the Mammalia, I am not unwilling to admit, that there are certain points of resemblance with those of reptiles and birds, more particularly in the semi- cartilaginous state of the bones themselves, in the exposed situation of the cavity of the tympanum, in the very pecu- liar form of the stapes; but it must be evident, I think, to all, that certain of these deviations from the usual structure arise out of the deficiency in the osseous parietes of the tympanic cavity, and consequent attachment of the small bones of the ear, and the membrana tympani itself, to a portion of the pterygoid processes. On the other hand, the internal aspect of the cavity of the tympanum appears quite regular; the vestibular foramen, that which in Man, by a faulty nomenclature, is called oval, isin the Ornithorynchus perfectly circular. An attempt is made, by a projection of the bones, to divide the tympanum into two cavities, in one of which is situated the ossicula auditus, and the vestibular opening. By the wide opening into the other cavity passes the facial nerve, which escapes from the cavity by a hole close to the cochlear opening of the internal ear ; this latter is much larger than the vestibular. The principal branch arising from the superior cervical ganglion passes along the roof of the tympanum, and internally with regard to the stapes, on its way to join the fifth pair of cerebral nerves. It will be readily understood that the cavity of the tym- panum, which is inclosed partly by osseous, and partly by cartilaginous parietes, is considerable. Its anterior portion may be divided inte two principal cavities, viz. that which contains the ossicula and vestibular foramen, and that c2 $6 OBSERVATIONS ON THE ANATOMY OF which extends upwards under a portion of the temporal bone, forming the glenoid cavity, and consequently extend- ing towards the zygomatic arch. The posterior: cavity, whose parietes are in like manner partly osseous and partly cartilaginous, contains the cochlear opening, and a part of the facial nerve in its passage outwards. A strong osseous plate, proceeding from the temporal bone to the base of the styloid process, is that which chiefly divides the anterior and posterior cavities from each other; but as the parietes of this second cavity of the tympanum are cartilaginous on one aspect, viz: the lower, the foramen by which the facial nerve: escapes from the cranium is not completely osseous, but has about a third of its circle composed of cartilage. T shall conclude this sketch of the organ of hearing of the Ornithorynchus, by observing, that im no part of the ana- tomy of this:animal have I found a greater deviation from the strictly mammiferous structure, as in the formation of the tympanic cavity, and in the small bones contained with- in it. The position of the eyes in the upper and anterior part of the head, close to the edge of the flap, has been already noticed. ‘Fhe eye-balls are small, and placed deep in the orbits; they seemed to me quite regular, both as to inter- nal structure, and to the muscular and nervous parts si- tuated externally to the eye-ball: I could not pereeive very distinctly any lachrymal gland, though anteriorly there is a small duct, which would seem to lead into the cavity of the nose, and,. if real, may be considered as analogous to the lachrymal duct in the Mammalia. The convexity of the cornea belonged to a sphere not much smaller than the sclerotic; the lens is flat and soft; the orbit mcomplete. Owing to the long immersion in spirits the internal struc- ture of the eye-ball could not be distinctly made out, and THE ORNITHORYNCHUS PARADOXUS. 87 it would be tedious to describe its external muscles, which, so far as I could judge, did not differ greatly from those of the Mammalia *. 2. On the Poison-Gland and Spur. It seldom happens that Nature leaves animals unprovided with means of defence against their enemies, and she has furnished the Ornithorynchus Paradoxus with one of the most extraordinary which probably exists. ‘The compara- tive anatomists, as well of the Continent as of England, who first examined this animal, viewed the spurs as con- nected with the organs of generation: they were evidently peculiar to the male; and it was conjectured by Sir E. Home, and by the celebrated Cuvier, that they were merely accessory organs, and were accordingly classed with the organs of prehension. ‘They are thus described: in the Anatome Comparée: ‘ L’ergot de YOrnithorinque et de P’Echidné est composé de deux osselets ou de deux pha- dJanges, dont l'une tres court, applatie, s’articuli sur une fa- cette de l’astragale, située du cote interne et inferieur de cet os, et Lautre orgueale plus longe, de figure conique, sert de moule a la corne qui forme lergot. Cette corne est pointue, assez longue, fixée du coté interne de articulation ‘du pied, ayant sa pointe dirigée en dedans.”—'Tom. v. p. 116. _ A similar opinion was formed of the use of these spurs by most French and German anatomists. Some years after, a brief notice found its way to this country of severe cases of poisoning having followed a wound made by the spur of the Ornithorynchus. In consequence of this notice, the attention of anatomists was roused, and a specimen. ex- amined by Dr De Brainvitiz, and one by Professor * I thought I noticed a third eye-lid, though very small, 38 OBSERVATIONS ON THE ANATOMY OF Ruporrut, with a view to discover the poison apparatus, if any existed. The known excellency of these distinguished naturalists, as comparative anatomists, induces me to think that the specimens examined by them must have been ex- tremely mutilated, for their descriptions bear no resem- blance to the true anatomy of the poison-gland and spur. On the heel of each of the hind ‘feet there appears exter- nally a spur, much resembling that found in the common dunghill-cock. It is strong, semitransparent, and pointed ; and there is evidently an aperture at the point, or rather on its convex surface, and sloped, as if a small piece had been cut out of it, without shortening the spur. ‘Through this, a delicate black body, like a bristle, projects ; it seems of a horny consistence; though a strong magnifying glass was used, it did not appear to be hollow. On removing the integuments carefully, the spur is found to rest by its base on a flat bone, placed longitudinally over the tarsal bones, and situated between the lower extremity of the tibia (to which it is attached), and the tarsal bone corresponding to the inner toe. Its principal connection, however, is prin- cipally with the astragalus. In this way two joints are formed, viz. one between the bone on which the spur rests and the other bones of the tarsus, and the other between the spur itself and the bone. 'The motion in both these joints is inwards towards the tail, and this is the direction _ which the spur assumes, and the only one in which it can possibly wound. If a longitudinal section be made of the spur, it will be found to contain a comparatively large membranous canal, gradually increasing as we proceed to- wards the base; this membranous tube is contained in the centre of the spur, which immediately around it has a whiter appearance than the more external portions, but has no resemblance to bone, as some estimable authors -have stated : it 1s merely a litte firmer than the other parts THE ORNITHORY NCHUS PARADOXUS. 39 of the horn. As the membranous duct approaches the base of the spur, it becomes very strong, as if semicartila- ginous tunics were superadded to it; just as it quits the spur to enter the sole of the foot, the duct makes a sudden turn, and is much contracted; it next expands a little, and ~at this point its parietes are so thick as to give it the ap- pearance of a'bulb or gland, an appearance which, together with the deep situation of the sac in the hollow of the foot, Jed M. De Buatnvit.e to consider it as the poison-gland itself, and which evidently has been the cause of the very singular errors commited relative to the anatomy of the spur. When this bulb ‘is laid open, it is found to be merely @ continuation of the mucous canal, which has at this point become greatly strengthened in its parietes, and assumed an almost muscular appearance. In the hollow of the foot the duct opens by a sudden turn into a comparatively large sac, surrounded and inclosed by strong ligamentous and tendinous parts, connected with the small bones of the foot. From this sac or bag, which in either foot contained a good. deal of a brownish, mucous matter, arises the great duct leading to the poison-gland. ‘We may now trace this duct either from the sac towards the gland, or vice versa. If the first plan be adopted, we perceive that the duct en- ters the central sac by a small round orifice, and next makes 4, very sudden turn to reach the superficial part of the foot, and is soon found almost immediately under the integu- ments. From this point it proceeds towards the gland, gradually decreasing in strength of parietes, but increasing in diameter until it terminates, or rather commences in the poison-gland itself, situated over and somewhat above the hip-joit and lois. Throughout its course the duct lies imbedded in loose cellular membrane, and beneath the caudo-tibial muscle, which must be removed, in order to 40 OBSERVATIONS ON THE ANATOMY OF have a perfect view of the duct®. It is rather difficult to state the precise length of the duct from its origin in the poison-gland to its passage into the small sac situated in *the hollow of the foot; for about 1,$,ths of an inch its parietes are comparatively thin, and its diameter sufficient to admit.a common blowpipe. The remainder of the duct, and the sudden turn it makes to pass down into the centre of the foot and to reach the sac, have been already de- scribed. The poison-gland itself is about an inch in length, and yoths.of an inch in breadth. It is a conglomerate gland, that is, made up of smaller ones, imbedded ina tissue of a different appearance, and which is probably cellular. It lies longitudinally with respect to the spine, immediately above the hip-joint, and close to the os innominatum of the corresponding side. It advances but little towards the loins; it covers many of the muscles which rotate the thigh, and may readily be found by merely removing the integu- ments, panniculus carnosus, and a small quantity of loose cellular membrane lying over the os innominatum and ‘hip- joint. ; The functions of these parts may now be very readily understood. The poisonous fluid secreted by the gland is conveyed by the long duct into the sac situated deep m the hollow of the foot close to the heel. From this it is pro- jected into the membranous canal contained in the centre of the spur, and which, by an almost inexplicable error, has hitherto been mistaken for a bone. Along this it will easily flow into the wound inflicted by the spur, passing through ® The whole anatomy of the Poison Gland and Duct, has been beautiful- ly depicted by the artist I employed, Mr R.'Macinnes ; and the cireumstance, .that none of the artists employed had the least knowledge of the anatomy of ithe parts, will no doubt be deemed of considerable importance by many. oot at EC Wern.

A varied; that of G. Griffithtanum being perhaps the most remarkable, and resembling concave fovce or pits, rather than regular cellules. G. ovatum is worthy of notice, from its leaves having a mass of minute round gemmee on their nerve and centre. In regard to form, the leaves differ con- siderably ; in G. Griffithianum they are nearly round; in G. ovatum ovate, with a hair-point; in G. microstomum and Donianum subulate; and if Drepanophyllum of RicHARD, Hooxer *, and ScHW&GRICHEN +, be added to the genus, they are sometimes falcate. They are also either acute or obtuse, entire, dentate or serrate, usually slightly concave; but in G. involutum, they are remarkably invo- lute; and in G. julacewm convolute; their arrangement on the stem is in every instance imbricated; the doubtful Drepanophyllum alone having them inserted bifariously. In none of the species are the cauline ones destitute of a nerve. Ozs. In this genus the two opposite extremities exhibit little in common; yet, with the exception of Drepanophyl- lum, the species may be said to form an uninterrupted se- ries. Some bear a near affinity in general habit to other genera; as, for instance, G. Griffithianum to Splachnum, and G. microstomum to Weissia, &c.: such anomalies, however, must necessarily occur both in the embryonate and exembryonate tribes of vegetables. Of the above ex- amples, however, G. Griffithianwm is not m reality so closely allied to Splachnum as has been by some imagined ; the reticulation of the leaves is of a very different nature, and the thick carnose seta is totally at variance with that - genus. * Musci Exotici, tab, 145. + Sp, Musc. Supp. 2. tab. 125. 46 NEW ARRANGEMENT OF Drs Hooxer and Taytor have said (Muscologia Bri- tannica), ‘* A delicate horizontal annular membrane may be seen to arise within the mouth of the capsule of some species, when examined in a fresh state, as in G. microsto- mum, G. fasciculare, G. truncatulum, and, above all, in G. Griffithianum, in which, not unfrequently, this mem- brane is entire.” And afterwards, ‘‘ The membrane stretch- ing across the mouth of the capsule is only to be seen in fresh specimens.” Should this membrane in the latter moss be found hereafter to arise from the stoma (which, indeed, we very much doubt, but which, if it were the case, would bring this extraordinary plant under Brown’s character of Hymenostomum), and not to be a mere cover to the spo- rular sac, it would lead to the formation of a new genus. Scuw#¢ricHEen, indeed, in his Second Supplement to Hepwie’s Species Muscorum, has ventured to constitute of it a genus from such dried specimens, as in which he confesses he never saw the character: he has called it Qdi- podium, and has separated it from Gymnostomum, because it has “ peristomium nullum aut exigua membranula indi- visa.” Now, every moss possesses this ‘‘ membranula indi- visa,” arising from the lining of the theca; but in all the species of Gymnostomum, it is peculiarly evident at some particular stage. In our description of the fructification, we have noticed the columella, which, in some few species, is of a most re- markable form. Dr Hooxer has delineated a curious ex- ample in G. Xanthocarpum, and we have added that of G. pyriforme in one of the plates accompanying this paper. In the latter, if a specimen be taken before the fructification be quite mature, and the operculum with the opercular membrane be forcibly, but carefully detached, we perceive a membranaceous expansion, which, if the sporules be re- moved, resembles an inverted cone, the base or superior THE GENERA OF MOSSES. ANY portion of which, is attached all round to the sporular bag at the margin of the theca. That part of this membrane which unites the Iming of the theca to what is usually called the summit of the columella, is in this genus com- monly of a strong nature,—so much so, as to induce Mr Brown, and also ourselves at one time, to conclude that G: microstomum * possessed a horizontal membrane actual- ly arising from the wall of thetheca. This, however, is not the case: but even supposing it were so, the difficulty of examination is so great, and the membrane itself so eva- nescent, this character alone would be but of little use, though certainly sufficient to remove any plant from the true Gymnostoma. With the membrane which covers the sporular bag, the peristome of Leptostomum must not be confounded. In that genus, Dr Hooxer remarks, that the peristome is very near that of Diphyscium ; and we add, also, to the internal peristome of Buwbaumia and Ptychostomum, (Hornscn.)\; but Leptostomum and Piychostomum we think more natu- rally allied to Bryum. We have already mentioned that some species possess an annulus. Dr Hooker, in his “* Musci Exotici,” has figured two, G. julacewm and involutum. Weber and Mour (Handbuch, p. 86.) first pointed out this part in G. tenue,— Arte solventes operculum, annulum s. fim- briam, cujus nec Hepw. nec Scurap. mentionem fecerunt, observavimus.” ‘This was soon afterwards also observed. by Routine. To these three must be added, G. trichodes ® Mr Brown constitutes of this plant his genus Hymenostemum, with the character——“‘ Stoma edentulum, clausum epiphragmate (e membrana exteriore orto), disco tenuissimo (a columello libero) mox rupto et evanido ; limbo persistente, horizontali indiviso.”.«-Linn.

We shall conclude our observations, by noticing, that Sir James Enwarp Smirn alludes to the Hyssop of Soromon being contained in this genus, and states it (according to the Linnean Herbarium) to be G. fasciculare*. Wuzen — and Mour do not seem certain as to the species; and Pauissor DE BeEavvois, without assigning any reason, ~ changes it into a Phascum, as, when speaking of the Phasca, he observes, ‘ parmi lesquelles on croit recon- noitre PHyssope de Salomen.” The last notice of this sub- ject is to be found in Mr Gravy’s extraordinary work on British Plants, where he gravely adds, and with his usual brevity, the following synonym, under Gymnostomum fas- eiculare: “ The hyssop that groweth on the wall.—English Bible.” ! We shall only add to the above, conceiving the whole to be a matter of mere speculation, on which every one has a right to say what he pleases, and without much danger of refutation, that it is as probable that the hyssop may be nei- ther a species of the genus Hyssopus nor of Gymnostomum. If we examine the New Testament, we shall perceive, that at the time of our Saviour’s crucifixion, when he thirsted, that they filled a sponge with vinegar, and placed it on hyssop, “6 yoowmw mepibevees,” im order to extend it to him, (St John, ch. xix. v. 29.) Now, Matthew uses a different expression ; he says, they put the sponge on a reed, “ xs wegibes xard- #9,” (Matth. ch. xxvii. v. 48.) And Mark, (ch. xv. v. 36.,) confirms this, zegibes r= xecaduo.” From these authorities, one might infer, either, that hyssop was a reed, or, as xaAdjos * Fl. Brit. p. 1166. and Eng. Bot. t. 1245. 9 a “THE GENERA OF MOSSES. 49 may be a wand, or slender branch of any kind, so codes is the bush or tree from which the twig was taken; but which- ever be the reading, the hyssop of St John can neither be the herb known at this day under that name, nor any of the Musci. In interpreting rigorously the passage in 1. Kings, ch. iv. v. 33. we do not find any thing dissonant to this: “¢ And he spake of trees (lignis in the Vulgate, and Zoaay in the Septuagint), from the cedar that is in Lebanon, even unto the hyssop that springeth out of the wall.” But might not hyssop have been the name for any small plant, in con- tradistinction to the magnificent cedar * ?

The Mosses composing the present genus, formed with DittEenivus and Linnazus a part of Brywm. At that period. no attention was paid to the peristome; but as soon as Hepwic commenced his work of reformation, the genus Gymnostomum was established: and at the same time was described another genus nearly allied to it, by the name of Hedwigia, the same as Anictangium of the Species Musco- rum. In that work fifteen Gymnostoma are published, and seven Anictangia, from which must be deducted, as bemg varieties, or belonging to other genera, the following; from Gymnostomum five (of which one is Schistostega), and from Anictangium six species (of which one is a Gymno- stomum, and another an Hedwigia). In the first Supple- ment published by SCHWEGRICHEN, twenty-four species of the one, and ten of the other, are enumerated. BripEL in his last work gives us no fewer than four genera formed. out of the above, Gymnostomum, Pyramidula, Schistidium, and Anictangiwm ; of which, the first contains thirty spe- cies, the second one, the third six, and the last two: Pyra- midula, however, is a true Gymnostomum, and ranks next to G. pyriforme, and of his two species of Anictangium, the THE GENERA OF MOSSES. 51 _one is a variety of a Gymnostomum, and the other an Ortho- tricum. Upon the whole, there are scarcely more than twenty-nine or thirty true species known of Gymnostomum, including those described by Dr Hooxrr in Muse. Exot., (with the exception of Mr Brown’s Leptostoma, which we conceive to form an excellent genus). In Great Britain, Sir James Epwarp SMITH enumerates sixteen species (F'l. Brit.) ; these he increases in his Compendium to twenty ; but Drs Hooxer and Taytor, in their Muscologia Britan- nica, reduces them to fourteen. | There are a few plants which require to be noticed in this place, some of which have been denied to belong to this genus, and others improperly retained. CEdipodium, the new genus constituted by Scuwaz- GRICHEN, we have already mentioned. Gymnostomum trichodes has been described by Hrpwic as an Anictane gium, by Suiru as a Grimmia, and as a Weissia by Drs Hooker and Taytor. We are more inclined to follow Werzer and Mour, and other authors, who deny it a peristome, than those who hold a contrary opinion. The authors of the Muscologia Britannica observe,— ‘¢ The curious peristome of this plant, in an early stage, represents only a membranous ring, lying horizontally within the edge of the mouth of the capsule: this, however, as maturity advances, splits into sixteen equal, short, and very obtuse teeth, which become erect, and afterwards re- flexed over the mouth of the capsule.” Sir J. EK. Smiru, in Eng. Bot. tab. 2563, also remarks, “Mr Borrer ob- serves, that the frmge seems a continuation of the inner coat of the capsule, and looks at first like a thin inflexed membrane, nearly closing the mouth; afterwards, when dry, it becomes reflexed, forming sixteen very short, blunt, flat, and pale teeth, and soon falls off—Mr J. D. Sowrrsy found each tooth divided by a line, transversely furrowed, D2 52 NEW ARRANGEMENT OF and occasionally emarginate *. Now, it should be observed, . that these teeth, which are acknowledged to arise from the interior of the theca, appear to be a continuation of the lin- ing; whereas, in all the Weissie, the teeth either spring from the surface of the stoma, or immediately from within ; and are formed at the same time with the theca itself; but the supposed teeth being thus only formed by the splitting of the horizontal membrane which connects the lining of the theca with the summit of the columella (and which we have already remarked to be peculiarly strong in Gymno- stomum), the plant should perhaps be retained among those destitute of a true peristome *f. Dr Hooxer has published a new and smgular species of Gymnostomum in his exquisite Musci Exotici [, under the name of Capense, which Mr Brown conceives to form of itself a distinct genus, named by him Glyphocarpa }. Unfortunately the latter has published no character; but, whatever it be, it assuredly ought not to rest on the form or strize of the theca, as, by the same principle, G. Lappo- nicum might also be removed; and Bartramia arcuaia, on ® By the plate in English Botany, the peristome is decidedly that of an Orthotrichum ; and indeed were the Muscologia Britannica and English Bo- tany description of actual teeth to be correct, we would feel rather inclined to constitute of this a new genus, and arrange it close to Calymperzs, in the Orthotrichotdee. + Since the plates for this paper have been engraved, we have observed, in Gym. microstomum, a similar structure, the horizontal membrane, which is usually striated, being, by age, turned upwards into sixteen very obtuse teeth.

As long, therefore, as generic distinc- tion is rigorously taken from the fructification, it will, if Dr Hooxer’s character be correct, remain in that group among which he has placed it. Depranophyllum of Ricuarp, first published by Dr Hooker as a Dicranum? is another very extraordinary plant, which we have hitherto alluded to in the light of a doubtful Gymnostomum ; the fact is, no character has yet been formed which excludes it from that genus. From its most peculiar habit alone, we have no hesitation in believ- ing it to be totally distinct; at the same time, the little that is known about it, renders it impossible for us to notice it, except in this place*. Scuwa#e¢RicHEN also describes and figures it in his second Supplement, and makes the sole character depend on the naked male flowers. Were we to hazard an opinion, we should be inclined to consider it an Anictangium, and not far from An. torquatum, with which it has a considerable affinity ; and if its calyptra be ultimately proved to be mitriform, we would feel inclined in that case to destroy the next genus we are to describe, Schistosiega, and form the whole into a distichous-leaved section of Anictangium. : ' Species referable to other genera, are, G. pennatum (vid. Schistostega), G. aquaticum (vid. Hedwigia). G. pulvi- natum and subsessile belong to Anictangzium. G. prore- pens, retained as such by all authors, we have ascertained to possess sixteen geminate teeth, without a capitate colu- mella, so that it belongs to the Orthotrichoidee.

Lxrstiz’s hygrometer has explained some of the phenomena attending the Sirrocco wind, which is the SW. and SE., but more particularly the SW. winds. You will observe by the register the extreme moisture of all the south winds, and the no less remarkable dryness of the north winds. The extreme moisture of the south winds, and the very frequent appearance of sheet-lightning during their conti- nuance, seems to indicate their being highly electrical; and the fact, that meat will not cure, wine keep if bottled, or paint dry, during a Sirrocco, I think favours the supposi- tion (not to speak of its very unpleasant effects on all living beings, such as are invalids particularly), that its great moisture alone could not produce aii those effects. I re- gret having no means of making any experiments on its electrical properties, but hope on my return to do so. I am, &c. M. MItyer. P.

By Rozert Knox, M.D. Prenabet of the Wernerian Natural History Society, and of the pedro Chirurgical Society of Edinburgh. (Read 22d November 1823.) CRATE eer SIN CE my first observations on the discovery of the fo- ramen centrale in reptiles were written, I have had an opportunity of examining, through the kindness of Profes- sor JamESON, the anatomy of a large variety c of the Cha- meleon, which had been sent to the Museum of the Uni- versity by the Marchioness of Hastings. The conjecture offered by me formerly, that the foramen centrale would be found to exist in the eye of this animal, was now con- firmed ; for the whole of this very singular structure, viz. the foramen, and the fold of the retina, are remarkably developed in the chameleon, and actually much larger than in the human species. There extends also from the entrance of the optic nerve to the foramen, a fissure, which, how- ever, 1s not real, but apparent: this semblance of a fissure ; PLATE Iv. AN \ \\ SAAN \ “UNA MAY a \ \) ALAN LAN \ Oe O27 Werye. Alem. Vob. Vp IN THE EYE OF THE CHAMELEON. 105 is caused by a remarkable thinness of the retina at this point. The retina around the foramen has adhering to it a quantity of black granulated matter, which it probably . receives from the choroid. Exactly at the point corresponding to the foramen, the choroid is somewhat elevated internally, whilst it transmits externally a dark-coloured membranous canal or tube to the sclerotic. ‘This is the only point at which I have found the choroid adhering to the, sclerotic in these animals. Nothing novel is shewn by examining the foramen cen- trale under the microscope, but the structure is naturally rendered more distinct. We perceive that the foramen is not quite circular, but somewhat irregular in its margin, and that the actual aperture is smaller than might be other- wise supposed. ‘This diminution in the real size of the aperture is owing to a thin semitransparent layer, proceed- ing from the more solid and opaque retina towards the centre of the aperture. I hope soon to be able to submit to the Society some further researches on this subject. T ought perhaps to have added, that most of the dissec- tions detailed in this and in my former paper announcing a the discovery, were performed in the presence of numerous & fiends, ; most of the preparations are in my possession, and will be deposited 3 in the Museum; but I have reserved a few specimens, lest any of the members of the Society, ac- customed to minute research, should desire to examine the structure for themselves. Haplanation of Plate IV. Fig. 1. Represents the head of a variety of the Lacerta superciiosa. ‘The eye was dissected in situ; the whole dissection consists in snipping off with a pair of 106 ON THE FORAMEN CENTRALE, &c. very sharp scissars the anterior third of the eye-ball, including the cornea and iris: the lens and capsule of the vitreous humour must now be very carefully re- moved. with a fine brush. I have thought it worth while to mention the mode I adopt in displaying the retina, because, by its adoption, any one, whether ana- tomist or not, will readily ascertain the presence or ab- sence of this very extraordinary structure. The black point 6, marking the entrance of the optic nerve into the interior of the eye-ball, may rea- dily be distinguished from the foramen centrale (a), by the little marsuprum which has been left attached to the former. I regret that the drawing had not been taken from the eye of the chameleon, in which the structure is naturally so greatly magnified. Fig. 2. The eye-ball viewed posteriorly, to shew that the transparent Point of Scemmering is really a foramen. The sclerotic c, and choroid d, have been removed, leaving the retina (marked ¢), in which the foramen (a) is distinctly visible. 6, marks the entrance of the optic nerve. Fig. 3.

COLOR » VIL—Contribution to a Natural and Economical History of the Coco-Nut Tree. By Mr Henry Marsnatt, Surgeon to the Forces, and Author of Notes on the Medical Topography and Diseases of the Interior of Ceylon. (Read 22d November 1823.) ‘Tue Coco-nut tree (Cocos nuciféra) belongs to the class Moneecia, order Hexandria, of the Linnean classification of plants. Stem erect, without branches, from 60 to 90 feet in height, and from one to two feet in thickness. It is marked with parallel rmgs from. the cicatrices of the fallen leaves, about two of which separate annually. By these cicatrices or marks the age of a tree is ascertained. The stem is crowned with a bunch of about twelve or fifteen fronds (palm-leaves), each twelve or fourteen feet long, and composed of a double row of opposite sword- shaped leaflets, in length from three to four feet; upper leaves are erect, middle horizontal, lower ones. rather drooping. A single leaf closely resembles a greatly magni- fied ostrich-feather. i 108 NATURAL AND ECONOMICAL HISTORY The flower is axillary, and proceeds from a large single- leaved pointed spathe, which always opens on the under surface. The spadix is spicate; each spike has towards its base one or two female flowers, the others being male. In both male and female flowers the calyx has three divisions, and the corolla three petals. ‘The male flowers have six stamens, and the female three stigmas. Drupe oval, three- sided, about from eight to ten inches long, exterior cover- ing smooth, interior fibrous ; nut monospermous, very hard, has three unequal holes at the base closed with a black membrane ; medullary part nearly half an ich thick, white, hard, commonly filled with a sweetish watery liquid. Ripe nuts are known by a succussion of the water they con- tain, when shaken. | A reticulated substance, resembling coarse cloth, involves the base of each leaf; it falls off before the leaf has attained a state of maturity. In Bengal, this filamentous body is supposed to harbour insects, which are destructive to the tree: on that account, it 1s there destroyed by fire. The roots are slender, and very flexible: they rise sepa- rately from the bottom of the trunk, some sinking deep in the earth, while others take a horizontal direction very little under the surface. ‘They do not penetrate an indurated soil. The young tree bears a near resemblance to a herba- ceous plant; imdeed, during the whole progress of its growth it has some analogy with vegetable productions of this kind. ‘The stalk of some species of Brassica (or Cab- bage genus) consists chiefly of pith, until the plant attains a certain age, when the exterior crust of the trunk becomes ligneous, and the proportion of pith diminishes. In several respects the Coco-nut tree has a similar progress. It has no brak ; the surface appears to be formed of the cicatrices, which succeed the fall of the leaves, much hardened by the. OF THE COCO-NUT TREE. 109 action of the air and sun. A slight wound in the central bud is fatal to the tree; but the hardened trunk is capable of bearing considerable injury with impunity. Coco-nut trees are often struck by lightning, which fre- quently kills the terminal leaf-bud, and thereby occasions the death of the tree. This tree never changes the diame- ter it has once acquired. Should any circumstance occur capable of retarding the growth during one or more years, such as transplantation, the effect is very evident in the stem by a permanent contraction in its diameter. Immediate- ly above these strangulated parts small roots sometimes protrude, but they seldom extend beyond a few inches. Frequently the trunk has a larger diameter at the base and top than in the middle. The wood of the stem is composed of hard, flexible, lig- neous, black fibres, united by a soft brownish pith, or cellu- lar substance, capable of being reduced to powder. ‘ The palms have in the interior structure of their trunks no ana- logy with other trees. In habit and in structure they re- semble the ferns, in their blossom the grasses, and the aspa- ragi in their mode of fructification*.” All the palms have in a greater or less degree a spongy structure. The cellular substance of the Cycas circinalis (Sago-palm) is, in some of the islands of the eastern Archipelago, manufactured imto the nutritive substance called Sago. The Caryota urens (Nepery tree) yields a considerable quantity of fecula, or sago; but in Ceylon this substance 1s not extracted, except during a period when rice is scarce. Sago 1s easily ob- tained from the interior part of the trunk of these trees. The process consists in pounding the spongy or cellu- lar texture of the stem, and washing it with water, which is strained, to separate the ligneous fibres from the feculent * Marre Brun. 110 NATURAL AND ECONOMICAL HISTORY substance. The process of granulating sago is not practised in Ceylon. The exterior lamina and base of the stem of a Coco-nut tree is always much harder than the interior and upper portion. There is a palm called the King’s Coco-nut, the fruit of which has a bright yellow colour, but it does not appear to be a different species from the Cocos nucifera. Nuts of this kind contain a great proportion of fluid, which, on account of its supposed cooling quality, is given to inva- lids, in preference to that of the common nuts; but they are not esteemed so good as common nuts for culinary purposes. . ! The nut known by the name of the Maldive Coco-nut, Coco de Mer, Zee-calappers, T'avarcarse, Sea Coco-nut, Double Coco-nut, Nux medica (Borassus Sechellensis), is the produce of a palm-tree, which Rocuown tells us abounds in the Isle of Palms, one of the Scychelle Islands, but no where else. ‘The fruit presents an appearance of two thighs ; in other respects it is not materially different from the com- mon coco-nut. The nuts which are occasionally found at the Maldive Islands have been carried by the current from the above-named Island. When the Maldive traders arrive at the ports of Galle or Colombo, in Ceylon, which they usually do once a year, it is customary for them to make a present to the governor of the island, or the commanding officer of the garrison, in a very formal manner. On this occasion, I have known a small portion of the kernel of one of these nuts form part of the donation; from which it may be inferred that they imagine it to be an article of some value. Great medicinal virtues are ascribed to this nut by the Indians, both in the prevention and cure of diseases. The — venereal disease is supposed to be radically cured by it. THUNBERG says, it is deemed a sovereign remedy against 3 OF THE COCO-NUT TREE. ill the flux, the epilepsy, and apoplexy. Rocuow tells us that it was not uncommon at one time to see them sold for up- wards of L. 400 sterling each. The Emperor Ropotruus the Second could not proctire one at the price of 4000 flo- rins. Some of the wealthy Indians had cups made of them, which they ornamented with gold and precious stones. They are now more generally diffused than formerly, and consequently much less valuable. Maitre Brun informs us that it has been found profitable to cultivate them in the Isle of France. Many of the mendicants im Ceylon have nuts of this kind, in which they put the provisions they re- ceive in alms *. ; The Coco-nut tree, both in regard to the variety and utility of its products, is the most interesting of the palm tribe, “ the princes of the vegetable kingdom.” The tree sometimes bears fruit in five or six years from the time it is transplanted from the seed-bed, but the pro- duce is rarely abundant before the eighth or ninth year. It continues to yield fruit for sixty or seventy years. In good soils, and particularly during wet seasons, the tree blossoms every four or five weeks; hence there are gene- rally fresh flowers and ripe nuts on the tree at the same time. ‘There are commonly from five to fifteen nuts in a ‘bunch ; and, in good soils, a tree may preduce from eight to twelve bunches, or from 80 to 100 nuts annually. Coco-nut trees are sometimes much injured by various: species of Scarabeus, particularly the Scaradcus rhinoceros. They excavate a liole of about an inch diameter in the ter- minal leaf-bud, and, when the leaves expand, the leaflets “appear full of holes, as if they had been battered with shot of different sizes. In consequence of the injury done to the bud by this insect, the trees are sometimes killed. * System of Geography by Maite Bron, vol. iv. p. 420. THUNBERG’S Travels, vol. iv. p. 209. 112 NATURAL AND ECONOMICAL HISTORY This species of the Palm family has its habitat in inter- tropical Asia, Australia, America, and Africa. It is by some authors said to have in ancient times been cultivated in Arabia, but Nresunr informs us that it is not found to the north of Mocha. Like all other equinoctial plants, the Coco-nut tree becomes less luxuriant as we approach the Tropics. At the suggestion of Mr Duntop, who lately, in go able a manner, superintended the work now in progress, to clear Saugur Island, at the estuary of the Hooghly, that den of tigers is likely soon to be a continued grove of coco trees. Saugur lies in N. Lat. 21° 30’, which is perhaps as far from the Equinoctial Line as this species of palm can be cultivated with advantage. In the neighbourhood of Lucknow, which lies in N. Lat. 26° 24’, the Coco-nut tree grows, but it does not produce fruit. I am informed by Dr Bucuan, Deputy-inspector of Hospitals, who was for some time on duty in Egypt, that it is not found in that part of Africa. As the Coco tree seems to require for its perfection a mean temperature of not less than 72° Faun- RENHEIT, the proper climate for it will therefore be from the Equator to the 25th parallel of latitude, and in the Equinoctial Zone to an altitude of about 2900 feet. This general statement will no doubt admit of some qualification in regard to particular situations. There may be exposed spots within its favourite climate where the fruit will not come to maturity, and warm valleys beyond the above limits where the tree will grow, and perhaps produce ripe nuts. The Coco tree occupies, therefore, a zone of 25° of latitude on both sides of the Equator, which includes nearly four-fifths of Africa, one-sixth of Asia, one-third of Ame- rica, and excludes Europe. It may be remarked, that trees which grow on the immediate neighbourhood of the sea are much more luxuriant and productive than those which are planted inland or upon elevated situations. The cause of this OF THE COCO-NUT TREE. 113 degeneration is not very evident, it cannot invariably be attributed to a reduction of temperature. The Coco tree is much cultivated on some parts of the east coast of Ame- rica; from the river St Francisco to the Bar of Maman- guape, or from about 77° 30’ to 10° S. Lat., being about 94 leagues, the Brazilian coast is with few breaks planted with Coco trees. ‘The small island of Itamaraca, which is only three leagues in length, yields annually about 360,000 nuts *. But perhaps this palm is no where so extensively cultivated as in Ceylon, and the following remarks regard- ing its products are intended more immediately to apply to the tree as it grows in that island. ‘The Coco tree is culti- vated both in the interior of Ceylon and along the flat country adjoining to the sea; it thrives best, however, on the coast of the south-west aspect of the island, or from _Calpenteen on the north, to Dondrahead on the south. About the year 1813, it was estimated that 10,000,000 trees grew between these two points, and that since that period. the number has been annually increasing. The ex- tent of coast between Dondrahead and Calpenteen is about 184 miles; the whole circuit of the island is %54 miles. Except cinnamon, the products of the Coco tree form the chief staple commodities of Ceylon t. The Maldive Islands produce great quantities of coco-nuts; they are there said to be the price of labour. In Congo, this palm forms one of the greatest blessings in nature tf. ° | Kosten’ s Description of Brazil. +1 have attempted to detail the leading facts fevaniing the natural his- hg of the Cinnamon tree, the mode of preparation, and trade of Cinna- mon, in two papers, one of which is published in the Transactions of the Royal Society of London, for the year 1817. The other is inserted in the 10th volume of Dr Tuomson’s Annals of Philosophy. ~ System of Geography, by Matte Brun, vol. iv. p. 298. VOL. V. isi 114 NATURAL AND ECONOMICAL HISTORY It does not appear that the coco-tree is nearly as much cultivated in the West India islands as in the East. Mr STEWaRT, in his account of Jamaica, says, however, that “On some estates groves of them are planted, and an oil extracted from them to light the works during crop-time. Occasionally the nuts are served out to the slaves as an article of food.” | In many places along the coast coco trees thrive well upon the sandy soil near to the sea, where hardly any other plant will vegetate. Those coco groves, through which the eye can reach for a preat extent, inter- mixed with the huts of the natives, composed entirely of coco leaves, form a very picturesque object. When the trees are full grown, the bare trunks rise like columns of from 60 to 90 feet in height, while the horizontal pmnated foliage interlace, by which means a grove resembles the long aisles and Gothic arches of a cathedral; above these arches a profusion of fine leafy plumes rise from the centre of the trees, and project almost perpendicularly towards the sky, thereby adding greatly to the beauty and variety of the prospect. About twenty years since, the Colonial Government of Ceylon had it in contemplation to impose a tax upon coco trees, but, in consequence of the strongly marked aversion of the people to such a measure, the plan was abandoned. It is not unusual, however, for palm trees to be taxed directly, instead of indirectly, upon the products, as in Ceylon. On the Malabar coast, coco-nuts pay a land- tax of half a fanam for every tree that is in full bearing, old and young trees being exempted as unproductive. And, at Marzouck, in northern Africa, a tax of one dollar is levied upon every 200 date-trees *. ® Bucuanan’s Travels through Mysore, &c. vol. ii, p. 401. Lyon's Travels in Africa. OF THE COCO-NUT TREE. 115 The cottages of the inhabitants are always surrounded by a great number of palm-trees, more particularly of the coco-nut palm; and those plants seem to thrive best which are situated near to the dwellings of the inhabitants. This circumstance has given. rise to an observation of the na- tives, namely, that a coco-nut tree delights in conversa- tion. ‘The ashes which result from the burning of wood, for culinary purposes, is a more probable cause of the luxuriance of the trees close to the cottages, as the sweep- ings of the huts are generally deposited at the foot of a tree. ‘The cluster of trees which surrounds a hut is called a “ Toddy tope” by the English. 'ope is perhaps a cor- ruption of our word copse. Watte, a Singhalese word, is used to designate every description of plantation. Pol-watte signifies a coco-nut garden or plantation. I have already stated that the Singhalese almost always construct their huts under the dense shadow of palm-trees of different kinds. This comfortable mode of defending habitations from the direct influence of an ardent sun, seems to have in ancient times been practised in Judea (Judges, iv. 5.), and it is very generally adopted in all countries where the palm family is found to thrive.

When fully formed, but with a soft pulp, it is called EHlant by the Tamools, m Portuguese Lania. When a httle firmer, it is called enga in the Tamool language, and Coquo in the Portuguese. The mature nut is called Cotta tenga by the Malabars, and Coquo sicco by the Portuguese. In the Singhalese language, the nut 1s called Pol. The term Coco, by which this palm and its fruit is distinguished, 1s said by several authors to be of Portuguese origin. Bauutn tells us, that Coco, or Coguen, is derived from the three holes at the end of the nut, giv- ing it the resemblance of a Cercopithecus, a species of monkey. St Pierre, in his Harmonies of Nature, says, that a coco-nut, stripped ef its pericarp, bears an exact re- semblance to the head of a negro. Piso asserts, that the term Coco has been applied to the tree, on account of the sound emitted, when air is blown into one of the holes of the nut, having a resemblance to the voice of an ape. The Portuguese name for a monkey is macaco, or macoco. There is, however, better foundation for supposing that Coco is derived from the Greek word xoxes, a seed, or berry. UsEs. Roots.—This part of the tree is sometimes masticated by the natives in place of the areca-nut. The Brazilians make baskets of the small roots. The hard woody shell or crust of the trunk is employed by the natives in making drums, and in the construction of their huts, &c. It is also much employed for making gut- ters. ‘Towards the base of the trunk the wooed is remark- ably hard, and admits of a high polish. A transverse sec- tion of this part of the tree, when well polished and var- OF THE COCO-NUT TREE. 117 nished, has a lapideous gloss and beauty, which rival those of an agate. I have seen a polished portion of the wood set in the lid of a silver snuff-box, in the same manner as jewellers occasionally fix agates or cornelians. It might, I think, be found highly useful in ornamental cabinet- work, In some parts of the world, I am informed that a kind of cradle or couch for young infants 1s made of the reticu- lated substance formed at the base of the leaf. I never saw it applied to this purpose in Ceylon; it is there chiefly employed as an instrument of filtration, for straining the sweet juice which is extracted from the flowering spath of this tree. The Reverend J. CorpINEr asserts, that it “is manufactured into a durable sackcloth, called gunny, which is used in making bags for transporting grain,” &c.; and Captain PErcivat says, that it is manufactured into a coarse cloth called srinjakken (I presume he means ganja sakken) or gunny-cloth. If I mistake not, their statements are erroneous; gunny-cloth is made of hemp. Gunny or Goni is not improbably a corruption of ganja, the Hindos- tanee name of the hemp-plant (Cannabis sativa). Ac- cording to Bucuanay, goni-cloth is made: from the Ja- nupa (Crotolaria juncea) *. Sacks made of goni-cloth, are in India called gunny-bags by the English, and ganja sakken by the Dutch. The unexpanded leaves or terminal leaf-bud is occasion- ally eaten by the Europeans as well as by natives. When boiled it is tender, and forms a good substitute for cabbage. The natives sometimes preserve it in vinegar, and eat it as ‘a pickle. It may be observed, that the tree dies when this part is removed. Many of the indigenous inhabitants, as well as natives of as ourney through Mysore, &c, vol. i. p. 226, 118 NATURAL AND ECONOMICAL HISTORY Europe, thatch their houses with coco-nut leaves, in the Sin- ghalese language called polattu. Sometimes they are deno- minated ollahs, and at other times cadjans. The latter term has, I believe, a Malay origin. 'To prepare cadjans, the cen- tral ligneous portion of the leaf is divided longitudinally, the leaflets of each half are then plaited or interwoven, by which means they are adapted for a variety of uses. In this state they are employed to thatch cottages, to shelter young plants from the scorching rays of the sun, to construct fences, to form the ceiling of rooms, and to make baskets for carry- ing fruit, fish, &c. Sometimes baskets are made of palm- leaves, so close as to serve the purpose of buckets to draw water from deep wells. In the Maldive Islands, bonnetta, a species of fish, is preserved by a process in which coco- leaves are employed. The process consists in removing the back-bone, and laying the fish in the shade, occasionally sprinkling it with sea-water. After a certain period has elapsed, the fish is wrapped up in coco-nut leaves, and buried in sand, where it becomes hard. Fish thus pre- pared, is known in Ceylon, and perhaps over all India, by the name of cummelmus. The pieces of this fish brought to the market have a horny hardness. It is rasped upon rice, to render it savoury. The unexpanded leaves are employed to shew marks of respect to persons in power. When the Governor or Chief- Justice travels, lines, made of the stems of creeping plants, are stretched along on each side of the road, about three or four feet from the ground. Upon these lines young palm- leaves are suspended. The head civil servant of a district may command the inhabitants under his immediate con- troul to adorn the road along which he passes, but he is not warranted in claiming this mark of attention beyond his own district. 4 ° Vhe immature leaves of the coco-nut tree have a fine OF THE COCO-NUT TREE. 119 yellow colour, and a beautiful texture resembling fine lea- ther or satin. In some parts of Ceylon, the natives evince great taste in ornamenting triumphal arches, as also ball- rooms, and similar places of public resort, with the leaves of this tree, and some remarkably beautiful species of moss. As the young leaves are translucent, they serve to make lanterns, in the construction of which many of the inhabi- tants are very dexterous. The practice of shewing respect to individuals by means of the branches of palm-trees appears to be very ancient. See Matthew xxi. 8, Mark xi. 8, and John xu. 13. The fohage of the palm tribe of plants has been in many coun- tries considered an emblem of joy and victory, and hence the word palm is sometimes employed as a synonyme of victory and triumph. See Leviticus xxii. 40. In ancient times, when pilgrims resorted te Palestine, they commonly returned bearing palm-leaves; on this account they were denominated Palmers. Captain Lyon, when describing the amusements of the natives of some parts of northern Africa, informs us, that the dancers ‘* were directed by an old woman, with a torch in one hand, and a long palm- branch in the other, and sung in chorus verses which she repeated to them.” In the island of Otaheite, the female inhabitants wear bonnets constructed of the leaflets of the coco; and, in Ceylon, the European soldiers manufacture hats of small strips of the leaves, in the same manner that straw-hats are made. Indeed, broad-brimmed hats of this construction are frequently worn both by Europeans and natives, particularly by fishermen, who are much exposed ‘to the direct rays of an ardent sun. The leaflets are sometimes used to write upon, and the instrument employed to make the impression is an iron sty- lus. The leaves of the Palmyra (Borassus fiabelliformis), or Talipot (Corypha umbraculifera), are, however, much 120 NATURAL AND ECONOMICAL HISTORY more frequently employed for this purpose. Contracts and other legal instruments are often engraven upon tablets of copper, which have occasionally a border of silver. An allusion is made to the practice of writing upon tablets in Isaiah xxx. 8, and Habakkuk ii. 2. Palm-leaves generally undergo some preparation to fit them to receive the im- pression of the stylus. They are then called ollahs. The na- tives write letters to one another upon ollahs, which are neatly rolled up, and sometimes sealed with a little gum-lac. During the operation of writing, the leaf is supported by the left hand, and the letters scratched upon the surface with the pointed piece of iron. Instead of moving the hand with which they write towards the right, they move the leaf in a contrary direction, by means of the thumb of the left hand. To render the characters more legible, the en- graved lines are frequently filled by besmearing the leaf with fresh cow-dung. This substance is then tinged black, which makes the writing very plain. Sometimes this object -is obtained by rubbing the lines over with coco-nut oil, or a mixture of oil and charcoal-powder. The natives do not require tables to write upon; they can write standing as well as walking. Jne-ad _ Baskets for catching fish, shrimps, &c. are made of the ligneous ribs of the leaflet ; the same substance is employed by the natives for many of the purposes for which we use pins. A bundle of these ribs is in universal use, as a broom, to sweep the cottages; and when an European asks for a tooth-pick, his servant brings him a portion of one of these fibres. Lately, I am informed, they have been recommended to be employed as a nucleus for bougies. In a domestic state, elephants are fed chiefly upon coco- nut leaves, and this animal evinces much sagacity in sepa- rating the elastic woody fibre from the thinner margin of the leaf. OF THE COCO-NUT TREE. Pot For temporary purposes, cadjan-houses are frequently constructed, both by natives and Europeans. During the insurrection in the Kandyan country in 1818, many of the sick were accommodated in cadjan-hospitals. Except the frame-work, every part of the house, walls, and roof, is formed of coco-nut leaves. They are capable of resisting all kinds of weather for a year or more. To prevent thieving, the owners of topes frequently fix a coco-nut leaf along the stems of fruit-trees. As the leaf rustles much when touched, a thief is cautious of ascending the trunk of the tree, lest he should alarm some of the in- mates of the neighbouring huts. ‘THunsEere mistook the use of these leaves, and supposed that they supplied “ the place of ladders, by means of which the natives could climb up, and gather the fruit *.” : : ‘In warm climates, it is customary to travel during night, with the view of avoiding the infiuence of an ardent sun. Torches then become necessary, and coco-nut leaves are chiefly employed for this purpose. By tying the leaflets close to the centre-rib of a leaf, the ignition is prevented from being too rapid. ‘Torches of coco-nut leaves are com- monly denominated chels (ooloo attu, Singhalese); they are in constant use, to obstruct the inroads of wild beasts upon cultivated fields, more particularly of elephants. In the interior of Ceylon, every field under cultivation must be watched durmg night, to prevent the depredations which would be made upon the crops, were these animals to have free ingress. When burned, the coco-nut tree, especially the leaves, afford a large proportion of potash. ' ‘The caste of washermen avail themselves of this qua- lity, and procure all the potash they require by the incine- ne * Travels, vol. iv. p. 192, 122 NATURAL AND ECONOMICAL HISTORY ration of different parts of the tree. Soap is very little used by the native washermen in Ceylon. | Boats are rowed with the centre-rib of the leaf, in which operation it forms a substitute for paddles. The end of this part of the leaf is sometimes well-bruised, and thereby converted into a brush, that may be used for a variety of purposes. eG The spaths, or fibrous covering of the blossoms, are in- flammable; on that account they are often employed as torches. In some parts of India this part of the tree is soaked in water, and converted into coarse cordage, with which the thatch of houses is tied. Many useful products are derived from the flower and fruit of this tree. By a peculiar manipulation the flower yields a rich saccharine juice, convertible into arrack or sugar. The word arrack, or arak, or rack, is probably a corruption of the Arabic word wrugq, spirit or juice, indefi- nitely ; whence we may infer that the art of distillation was conveyed from Arabia to India and the eastern archipelago. We are informed that, in the Ladrone Islands, it is called wraca. In Ceylon, and many other parts of India, the term arrack is employed in a sense similar to that with which we use the phrase spiritous liquors. Distilled spi- rits, of whatever kind, obtain this denomination through a great part of Asia, and along the northern coast of Africa, In the Singhalese language, sugar, manufactured from palm-juice, is called hackurur, which is commonly corrupted by foreigners into jagery, and may be the origin of the Arabic word sukker. A Sanscrit scholar has suggested, that swear may be derived from the Sanscrit word goor (sweet); the superlative of which, he tells me, is seogoor (sweetest). Sweet jnice is extracted from the unexpanded flower, in the following manner :—A man, in colloquial language, OF THE COCO-NUT TREE. 123 called a “ Toddy-drawer,” cuts off the point of the spadix, and ties the stump firmly round with a ligature. It is then beaten with a stick; which operation is supposed to deter- mine the sap to the wounded part. This process is re- peated for several days, cutting off daily a small portion of the end of the spadix. Under this management, the juice soon begins to flow from the cut surface of the flower, and is carefully collected in an earthen-ware vessel, sus. pended from the spathe. A thin portion of the flower and spathe is sliced off daily, and the end of the stump is bound with a ligature. A good healthy blossom will give from two to four English pints of sweet juice daily, and some flowers will continue to yield juice for about four or _ five weeks. Hence there are frequently two spaths on one tree, yielding toddy at the same time *. I may here state the mode by which a toddy-drawer ascends the tree. He takes the dried stem of a creeping plant, and forms it into a circle of about a foot diameter. The feet are next put into this circular band. He then raises himself up a little on the stem of the tree, by means of his hands, and subsequently supports his whole weight upon the’ feet and the connecting ligature. By the alter- nate motion of his hands and feet, he reaches the top. The ordinary implements of a toddy-drawer, are, the shell of a large gourd, capable of containing several pints of sweet juice, and a broad knife, which he suspends to a belt tied round his waist. In Bombay, the stem is sometimes notched on each side, to enable the toddy-drawer to ascend the tree. # « The Gomuti Palm yields teddy for two years, at the average rate of three quarts a-day.”—Cnrawrurp on the Indian Archipelago. According to Lasinnarpiere, a date-palm will furnish, for upwards of two months in the year, six or eight litres of liquor a day,—-** Account of a Voyage in search of Perouse, by M Lasitiarpier®, vol. i. p. 334. 124 NATURAL AND ECONOMICAL HISTORY But when it is intended to draw juice from a “ tope” or cluster of trees, the toddy-drawer collects a quantity of some creeping plants, with which he connects the heads of a great number of trees. In some districts, coir-rope is used in place of these creepers. There are a number of species of creepers, suitable for this purpose, which have stems many yards long, The toddy-drawer selects a tree, of easy access, near to the centre of the tope, the trunk of which he surrounds with a number of bands made of some creepers, each at about a foot distance. He then ascends, by means of these bands, and passes along, from tree to tree, upon the connecting stems, assisted by the horizontal leaves, collecting, as he proceeds, the sweet juice, which he pours into the shell of the gourd, suspended from his waist, and conveys it to the ground by means of a line. The gourd is emptied by a person ready to receive it, and the lime is drawn up by the man on the tree. Juice is seldom drawn from a coco-nut tope, above six or seven months at a time, as this operation is supposed to exhaust the trees. During the intervening period, nuts are produced. d Toddy is the name given by the English to the sweet juices which are extracted from the different species of the palm tribe, including that of the coco-nut tree. It is per- haps a corruption of tari or tarce, the Mussulman name of the juice of the Palmyra palm, of which éar or fal is the Sanscrit name*. Ma, which literally means juice, is the Singhalese name of the fluid extracted from the flower of a coco-nut tree. Sometimes it is called Mee-ra (honey or sweet juice); seldom, however, except when prepared for making jagery. Among the inhabitants of the maritime provinces of Ceylon, it is frequently denominated sur, which is said to be a Sanskrit word. With the above ex- “ Bucnanan’s Journey. through Mysore, &c, OF THE COCO-NUT TREE. 125 ‘planation, the words foddy, ra, mee-ra, and suri, may be used synonimously. Fresh drawn juice is sweet, and has a peculiar flavour, in consequence of some extractive matter it contains; and, in general, it operates as a laxative. When it is intended to distil arrack from sun, the toddy-drawers seldom change or clean the pots into which it is received, hence the juice soon ferments, and emits an acid smell. In a half fermented state, suri is much relished by some Europeans. When it has become, by fermentation, highly intoxicating, the European soldiers, and the dissipated portion of the natives, drink it freely. To render this beverage acrid, the soldiers occasionally add green chillies ( ees cuss Srutescens ) to it. Is it not very probable, that the strong dank mentioned in Scripture was mee-ra, drawn from the flower of some of the palm tribe (palm-wine)? In several of the Oriental languages, there appears to be an intimate connection be- tween the words which designate honey, sugar, sweetness, and the juice of the palm family of plants. Mee, in the Singhalese language, means honey, sweet ; and the toddy, or juice extracted from palm trees, is called mee-ra. Juice drawn from the flower of the Sago-palm, is, by the Malays, denominated der (water) saguer. As the word saguer appears to be only a slight alteration from the Sanscrit adjective implying sweet, aer saguer will therefore literally mean sweet water, or the sweetest water. In the Javanese language, the juice of the Gomuti-palm is called lagen, which means the sweet material by distinction *. We learn from Suaw, that the Hebrew word rendered honey -in Scripture, is, by some commentators, supposed to deno- minate the sweet juice procured from palm trees, as well as the honey of bees. He tells us that, in Barbary, the sweet Juice extracted from date-palms, is called dipse ; and that * CRAWFURD. 126 NATURAL AND ECONOMICAL HISTORY dibse or dipse, which is a Hebrew word, is generally trans- lated honey in the Old Testament *. Dr Moszny, in his Treatise upon Sugar, &c. says, that the strong drink of the - Scripture was called shecar, a word which likewise means éntoxication. This word shecar, does not differ much in enunciation from the Sanscrit adjective implying sweet; and it very closely resembles the Malay name of the intoxicating toddy of the Sago-palm (Aer saguer). Dr MosELey con- cludes his disquisition on the strong drink of the Old Tes- tament, by saying, ‘* What sottish liquor shecar was, no person knows. It was probably made from grain, perhaps from honey +.” The suri pots are sometimes visited, and the contents carried off durmg night. ‘To detect the thief, the leaves of a species of datura are occasionally put into some of the pots. By means of the highly intoxicating effect of this compound, the marauder is often discovered. Arrack may be distilled from sur the same day it is drawn; but sometimes this operation is delayed for a few days, without diminishing the quantity, or injuring the quality of the spirit. The process of distillation is carried on, in the maritime provinces, in copper stills; but, in the Kandyan Provinces, earthen-ware vessels are chiefly em- ployed. Suri yields, by distillation, about one-eighth part of arrack, of the same strength as good brandy. Arrack, when well prepared, is clear and transparent: generally, however, it is slightly straw-coloured. It has a peculiar flavour, no doubt depending upon an essential oil which rises from the suri during distillation. Arrack is issued to the soldiers in India and Ceylon, as part of the established * Snaw’s Observations relating to Barbary and the Levant, vol. ii. p. 144, note. + Medical Tracts, by Dr Mosgxy, 2d edit. p. 138. ie) OF THE.

Ceylon exports annually, and, for the most part, to the Presidences of Bengal, Madras, and Bombay, from 5000 to 6000 leaguers of arrack, each containing 150 gallons. Including freight, duties upon exportation and importation, this spirit is sold at Madras at about Is. 3d. per gallon. The prime cost of arrack in Ceylon varies from 8d. to 10d. per gallon. It is stated by Mr Baxroxacct, that arrack distilled at Batavia, is said to be sold in India from 10 to 15 per cent. cheaper than that brought from Colombo.* Ten per cent. duty is levied upon arrack exported from Ceylon. In England, this spirit has brought as high a price as from 5 to 6 shillings per gallon. Batavian arrack is made from a mixture of molasses, palm-wine, and rice, in the following proportions: Molasses, - - - 62 parts. Toddy (palm-wine), - “ 3 ditto. Rice, - - - - 35 ditto. 100 parts of these materials yield 233 of distilled proof arrack. The rice is first boiled ; and, after cooling, a quantity of yest 1s added to it, and is pressed into baskets. In this condition, it is placed over a tub or tubs, for eight days, during which time, a liquor flows abundantly from the mixture. At the end of that time, the liquor which has subsided, is taken out and mixed with the molasses and palm-wine, which has been previously combined. The mixture remains in a small vessel for one day only, when “it is removed into large fermenting vats, in which it re- mains for seven. ‘The liquor is finally removed into the still; and, according to the number of distillations it un- * Bartoracci on the Revenue and Commerce of Ceylon. 128 NATURAL AND ECONOMICAL HISTORY dergoes, becomes arrack of the first, second, or third qua- lity in commerce. The above account of the preparation of arrack, is extracted from Mr Crawrurp’s work on the Indian Archipelago. Mr Marspren®* informs us, that the “¢ Palm-wine ” used in this kind of arrack, is obtained from the coco-nut tree, and that arrack of the first quality may be purchased for about 60 Spanish dollars; second for 50; and the third for 30; each leaguer of 160 gallons. At this rate, the best arrack may be procured for 20d. per gallon. It is at present manufactured chiefly for domestic con- sumption. | eg The phrase ‘“ Pariah-arrack” is often used to designate a spirit distilled in the Peninsula of India. Arrack, there prepared, is said to be often rendered unwholesome, by an admixture of ganja (Cannabis sativa), and a species of datura, with the intention of increasing its intoxicating quality. It is not clear, whether the term Pariah-arrack be colloquially employed to designate an mferior spirit, or an adulterated compound. 3 There is a spirit prepared in the neighbourhood of Ma- dras, called puttay or putta arrack, literally bark arrack. Puttay, in the Tamool language, signifies the bark of a tree. Dr Arnstte tells us, that the barks chiefly used in making arrack, are those of the Mimosa ferruginea, and the Mimosa leucophlea of Roxburgh +. Suri is the yest commonly used by bakers in Ceylon. By allowing it to pass into the acetous fermentation, an excellent vinegar is obtained.. A great variety of vegetable substances are pickled with vinegar of this kind. When it is intended to extract jagery from suri, great care is taken to prevent it from fermenting. The earthen- * History of Sumatra. + Materia Medica of Hindoostan.

After this operation, the pot is always well cleaned, then dried, and a small quantity of chunam (lime) is thrown into it, before being replaced. Sometimes a portion of the bark of a tree; whose name I do not recol- lect, is imtroduced into the receiving vessel, instead of chunam. ‘The lime perhaps contributes to check the pro- gress of fermentation. Almost immediately after the mee-ra is drawn from the tree, it is filtered through a portion of the reticulated substance found at the base of the leaf. The juice is then slow!y boiled in an earthen-ware vessel, until it becomes light coloured, and acquires a considerable degree of consistency. While still warm, and semi-fluid, it is poured into sections of coco-nut shells, where it soon becomes solid. ‘Twenty-four ounces of jagery may be pro- eured from a gallon of mee-ra. I state the quantity of jagery which mee-ra yields, on the authority of Mr Brr- ToLacci, who paid much attention to this subject. It would appear that mee-ra is richer in saccharine matter than juice expressed from the sugar-cane in the West In- dies. Dr Mosety, in his History of Sugar, says, “« We consider a pound of sugar from a gallon of cane-juice as good yielding.” According to Mr Crawrurpb, cane-juice in Java, yields, on an average, 25 per cent. of sugar. Jagery contains both the crystallizable portion of the juice, and a quantity of molasses, or liquid sugar; but, by a sub- sequent operation, they can be, in a great measure, sepa- rated. This coarse sugar is generally made into little loaves, having the shape of a hemispherical vase, from the form of the vessel in which it cools. It has a deep choco- late colour ; and, when broken, presents many clear shin- ing particles of sugar. In the Malay language, jagery 1s denominated goola or goora itan (black sugar or black sweet.) 130 NATURAL AND ECONOMICAL HISTORY The ordinary price of jagery is about 2d. per pound. It is the only sugar used by the native inhabitants, and no other is prepared in Ceylon. They enjoy the juice of the cane, by masticating the green shcots, but in no other way, although they have a name for sugar extracted in other countries from this plant, which is sinee or chince. ‘The common soldiers ordinarily use jagery ; and many Euro- peans of the upper ranks prefer it to a more refined species of sugar for sweetening coffee. Sugar-candy, which is chiefly imported from China, is the saccharine substance commonly used by the higher classes of Europeans in India. In some parts of the interior of Ceylon, particu- larly in the vicinity of Adam’s Peak, great numbers of the inhabitants support themselves by extracting a sweet juice from the nepery tree (Caryota urens), and manufacturing it into jagery. This tree grows spontaneously in the woods. The people thus employed, subsist chiefly upon coarse su-_ gar. ‘They occasionally procure a little rice and salt by barter, but they do not raise grain by cultivating the soil. There is some foundation for suppesing, that the sugar of the ancients, which seems to have been imported from India, was the produce of the palm family of plants, and not that of the sugar-cane. SatMasius, the commentator of Prrny, is decidedly of opinion, that the sugar of the moderns is the produce of a different plant from that which produced the sugar of the Greeks and Romans. All the authors on this subject, with whose writings I am acquainted, describe the sugar of the ancients as being of a very coarse quality, and mixed with a large portion of molasses, exactly resembling jagery, the produce of some of the palms. Virry, in his Account of Sugar, says ex- pressly, that ‘* le premier sucre apporté des Indes n’etoit qu’une moscouade (sucre brut). And, m an Essay upon the History of the Commerce of Venice, it is stated, that the sugar which was manufactured in Sicily, as early as OF THE COCO-NUT TREE. 181 1173, brought a higher price than that which they im- ported from Egypt or from India, by the way of the Red Sea. 'The extraction of sugar from the sugar-cane is much - more operose than from the juice afforded by palms; and this may be one reason why palm-sugar should be more early known than cane-sugar, even in countries where the sugar-cane 1s indigenous. Among the articles of commerce which the Venetians imported from Asia, about the year 996, sugar is men- tioned ; but whether it was the produce of palm trees, or the sugar-cane, cannot be satisfactorily ascertained *. It is the opinion of Mr Marspen, that the sugar of the an- cients was procured from palms. In his History of Su- matra he says, ‘ If the ancients were acquainted with sugar, it was produced from some species of the palms, -as the sugar-canes were not brought into the Mediterranean. from the coast, till a short time before the discovery of the passage to India by the Cape. The word saccharum is con- jectured to be derived from jagyree, which the French pronounce schagaree.” His opinion is corroborated by Dr Crawrurp, who informs us that, “ although the cane be a native of the Indian Islands, the art of manufacturing sugar from it is certainly a foreign art. ‘There is no name for sugar im any dialect of the Indian Islands, but a foreign one eula (perhaps a corruption of goor sweet); and this foreign one is pure Sanskrit. When Europeans first be- came acquainted with the natives of these islands, they found them ignorant of the manufacture of sugar from the eane. The Hindoo word gula (sometimes written gour) is indeed equally applicable to palm sugar as to that of the cane. I therefore suppose that the Hindoos instructed the Indian islanders only in the simple process of manufacturing the former, and that the manufacture of the latter was in- ~ * Essai de Historie du Commerce de Venise, p. 71. 12 ow 132 NATURAL AND ECONOMICAL HISTORY troduced by the Chinese, under the auspices chiefly of Europeans, and in times comparatively very recent.” I am aware, however, that Humsotpr infers, from some Chinese paintings which he saw at Lima, representing the different processes for extracting sugar, that this art is ex- tremely ancient in that country.—(Hssai Politique sur la Nouvelle Espagne, tom. 11. p. 425, 4to.) It is stated, upon the authority of the Crusaders, that the inhabitants of Tripoli, in Syria, were acquainted with the art of extracting sugar from the sugar-cane, as early as 1108. The process they practised was extremely rude, and: consisted in pounding the cane in a mortar with a pestle. At this time, they do not appear to have been ac- quainted with the means of employing fire in the making of sugar. ‘The expressed juice was set aside until crystals formed in it*. For a long time, sugar appears to have, in Europe, been confined to the apothecary’s shop; and, by some of the older authors, it 1s recommended as a good sub- stitute for honey, to render nauseating medicines palata- ble; this seems to have been the chief purpose for which it was, during a considerable period, employed. Sugar did not become general, as an article of food in Europe, until it was extensively cultivated in the West Indies and Ame- rica +. » * Fatconer’s Sketch of the History of Sugar. + Neither sugar nor the sugar-cane is mentioned in Scripture. The word Sweet-cane, which we find in two places of the Old Testament, Isaiah xliii. 24., and Jeremiah vi. 20., seems to express a different substance, most pro- bably cinnamon. In both passages, sweet-cane is mentioned as an article of merchandize, and not asa native of Judea, which the sugar-cane seems to be. It likewise may be inferred, that the substance here meant was con- secrated to religious uses. Now, we know that, under the Levitical law, cinnamon was required to compose the holy oil for anointing the tabernacle. Kurope is indebted to the conquests of ALEXANDER, for a knowledge of sugar. SPRENGEL, OF THE COCO-NUT TREE. 133 When intimately mixed with lime, jagery forms an ex- cellent cement, which resists moisture, and endures great solar heat. It is capable of taking on a very fine polish. Walls are prepared for receiving this covering, by wetting them with a strong infusion of the husk of unripe cocos; and the same kind of fluid is used for mixing and temper- ing the materials. In Madras, and some other parts of India, the flat tops of the houses are covered with this cement. It is much employed to cover columns, as also to form the ficors of rooms. Floors of this kind are some- times stained and made to resemble the finest marble. It is said that jagery-cement has succeeded very well in Hol- land. In 1813, Ceylon exported jagery to the value of 39,245 rix dollars. The Ceylon rix dollar at par, is equal to 1s. Od. Sterling. When the flower has not been injured, the tree bears nuts which are converted to many useful purposes. Young coco-nuts are much used by the natives as an article of diet. During the unripe state of the fruit, the shell is lmed SPRENGEL, in his Historia rei Herbarie, informs us, that the sugar-cane is a native of the banks of the Euphrates; and that the first account we have of the fabrication of sugar from this plant, is not earlier than the fifth century. From Arabia, this reed found its way to Egypt, and eventually to Europe. In 1306, it was common in the Island of Cyprus; and, a hun- dred years after, it enriched Calabria, and the coasts of Spain. While Spain was under the dominion of the Moors, the sugar-cane was cultivated in Andalusia, and sugar manufactured from it. From Sicily it passed to Madeira, and the Canary Islands. Early in the sixteenth century it was transported to America, by a native of Portugal. Ovinpo saw some sugar manufactories in operation at St Domingo, in the year 1513; and, in 1520, it was carried to the Continent of America. In 1535, GonzaLes pz Veiosa constructed the first cylinder for expressing the sugar cane; and, in 1641, canes were transplanted from Brazil to Barbadoes, and thence to the other West India Islands.-Humeoxprt’s Personal Narrative, vol. iv. p. 179; Jour- nal de Pharmacie, tom. ii. p. 386; Rees’ Encyclopedia, Article Sugar. 1384 NATURAL AND ECONOMICAL HISTORY with a pulpy substance, while the centre is filled with an aqueous fluid. This fluid is at first slightly astringent and sub-acid ; as the fruit ripens, it becomes sweetish, and not unlike the colour and consistence of the whey of milk *. When drank before the sun has far advanced, it is much cooler than the atmosphere, and is then a pleasant beverage. Natives, particularly when travelling, generally furnish themselves with a few unripe nuts (Lanzas -Por- tuguese), the water of which they drink, and eat the pulpy portion or kernel. Upon a few repasts of this kind, a man will labour from morning till night, without any other article of diet +. The native inhabitants of the coasts of some of the islands in the Equinoctial Zone, are more palmivorous than granivorous. Where a people can be satisfied with food so easily procured as the produce of the coco-nut tree is, in some tropical regions, they are little sensible to the ordinary motives which impel mankind to labour. The Reverend _ : Mr Corpiner says, and perhaps with truth, that the per- son who possesses a garden with twelve coco trees and two jack trees, has no call to make any exertion. The husk or fibrous pericarp of the nut is employed to polish furniture, and to scour the floors of rooms, &c. Birds, who build pendulous nests, commonly construct them of this substance. Its chief use, however, is in the ® The following are the proportions of the liquid contained in the nut, as given in the Journal de Pharmacie, tom, ii. p. 98., extracted from Trommsporrr’s Journal:—“ Le liquide est clair et-sans couleur comme de l'eau, sans odeur, et dune saveur douceatre semblable aux noix.

The word coi7, sometimes writ- ten cair, and caira, is probably derived from the Portu- guese substantive cairel, a periwig, or fringe. The Sin- ghalese word for coir is kohu. ‘To remove the husk, an iron-spike, or sharp piece of hard wood, is fixed in the ground; the nut is then forced upon the pomt, which passes through the fibres, thereby separating the rind from the shell. In this manner a man can clear 1000 nuts daily. Coir is prepared by soaking the rind in water for several months, and then beating it upon a stone with a piece of heavy wood. On the coast of America, where a running stream of water is not near at hand, the coir-manufacturers dig holes in the sand below high water-mark, and bury the rind of the coco-nut, before beating it. Subsequently it is rubbed with the hand until the interstitial substance be completely separated from the fibrous portion of the husk. The rind of forty cocos furnished Mr Koster with six pounds weight of coir. ‘The next operation is to twist the fibres into yarns, which are manufactured into cordage of all sizes. Coir is remarkably buoyant, and well suited for ropes of a large diameter. Until chain-cables were intro- duced, all the ships which navigated the Indian seas had cables made of this substance. Sea-water is said to be rather beneficial than hurtful to it. Coir-cordage, when properly prepared, is pliable, smooth, strong, and elas- tic: it is very well suited for running-rigging, more espe- cially where lightness is deemed an advantage, such as top-gallant studding-sail sheets, &c. On account of its contractility, seamen consider it not well fitted for standing rigeing. Dr Roxpurcu, in his observations on the com- parative strength of English hemp and other vegetable fibres, states, that he found hemp-rope and coiv-rope, when large, to be respectively as 108 to 87 in strength, and when 1360 NATURAL AND ECONOMICAL HISTORY smaller, as 65 is to 60. In the same paper (‘Transactions of the Society of Arts, vol. 11.), he says, ‘‘ Coir is certamly the very best material yet known for cables, om account of its great elasticity and strength.” The natives sew the planks together which compose their boats with coir-yarns. When twisted into yarns adapted for being manufactured into cordage, it is valued in Ceylon at about L.2 per candy (500 lb.) Large quantities of this substance are exported to the different ports im India. Under the Dutch Government about 3,000,000 Ib. were annually manufactured in the island. The quantity of coir exported from Ceylon in 1813, amounted to 4,048} candies, and each candy may be valued at 28 rix dollars, total amount rix dollars 137,649. Very lately a manufac- tory for the making of coir-cordage has been established upon a large scale at Recif, near to Pernambuco, on the coast of Brazil. Coir is much used in India in place of hair te stuff mat- tresses, cushions for couches, saddles, &c. It is also em- ployed to make brooms and brushes to white-wash houses. The kernel of the ripe coco-nut is not unlike the sub- stance of an almond either in taste or consistence*. It is “ The following chemical analysis of the kernel of the coco-nut I have extracted from the Journal de Pharmacie, tom. ii. p. 100:— «La partie charnue a le consistance de nos noix fraiches ; mais elle est plus tenace, d’un blanc éclatant, et d’une saveur douceatre.” ‘¢ Il resulte que le noyau, ou la partie charnue de la noix, est compose de beaucoup Whuile grasse, se figeant aisément, ce qui peut engager a lui donner lenom de beurre végétal, d’un liquide aqueux, d’albumine, et de sucre liquide (mucoso-sucré).” ‘¢ En jetant un coup d’ceil sur cette analyse, nous voyons que la noix du cocotier est une substance trés nourrissante ; car l’albumine est connue comme nourrissante quand méme elle ne servirait ici qu’a animaliser les autres matiéres vegetales. Le sucre et lhuile sont egalement connus comme v OF THE COCO-NUT TREE. 137 eaten by the natives, and frequently along with jagery. The natives of the Ladrone Islands eat it in lieu of bread, with meat and fish. Sometimes it is rasped into very small pieces, and mixed with dressed rice, to give it a peculiar flavour ; and occasionally it is pounded into meal, of which fritters and small cakes are made. In India this fruit is generally allowed to be very nutritious, and many suppose that it possesses the quality of inducing corpulence. By a little pressure the kernel may be made to yield a white fluid resembling milk. When the milk of cows or buffaloes cannot be procured, Europeans sometimes add this liquid to tea asa substitute. Another substitute for milk may be obtained by rasping a kernel, and mixing the scrapings with some of the liquid contained in a nut: this mixture requires to be strained. We are informed by Dr Prycxagp, in his Notes on the West Indies, that puddings are made of coco-nuts in Barbadoes. The ker- nel is sometimes pressed with honey and sugar, and used to make preserves, | When mature, the nut is much used in Ceylon, to fur- nish an oleaginous fluid required to prepare curry, a dish in very general use among all ranks and classes in India. For this purpose, the kernel is finely rasped by means of an iron instrument called a homeny, which resembles the rowel of a spur, and the raspings are washed with a small quantity of water, which is subsequently filtered. ‘The emulsion thus formed is boiled along with the meat, fish, or vegetable substance intended to be “ curried,” and des principes, nourrissans, Le noyau a beaucoup d’analogie avec le lait animal. Ce qui constitue dans le lait la matiere caseuse, est remplacé ici par le mucoso-sucre, et Phuile epaisse peut presenter le beurre du lait ani- ial. On peut separer ici Vhuile de la meme maniére qu’on sépare le beurre du lait.” 138 NATURAL AND ECONOMICAL HISTORY thereby supplies the-oily fluid necessary in the composition of curry. A due proportion of spices is added to the mix- ture before it is removed from the fire. When coco-nuts cannot be procured, ghee (clarified butter) is used as a _ substitute in the preparation of this delicious dish. In Bengal, and, I believe, over great part of the peninsula of India; curry is chiefly prepared with butter or ghee. The Ceylon or coco-nut curry possesses much of the flavour of the nut; it has a light-yellow colour, and is easily digested, the oily part of the mixture being seldom too abundant. But the chief product of the kernel of the coco-nut is an excellent oil: and, to extract it, two different processes are employed; namely, decoction and expression. When the former process is followed, the fresh kernel is finely rasped ; the raspings are next washed with water, which assumes a milky appearance ; and, by decoction, yields a limpid oil. If the emulsion be exposed for a night, it separates spontane- ously into an oily and a watery portion, and the oily part 1s purified by a very short boiling. To separate the oil, the operator, who is generally a female, lays the palm of her left hand flat upon the surface of the fluid; a portion of oil adheres to the hand, which is brushed off into a vessel by the right hand. The oil made in this manner ts nearly as colourless as water, and when newly prepared does not smell offensively. In the course of a few days, particularly if exposed to the atmosphere, it emits a disagreeable odour. On an average ten nuts are stated by Mr Barroracct to yield about a quart of oil; but Koster, who made the experiment, says, that thirty-two nuts rendered him only 8 |b. of pure oil. Compression is the process. chiefly adopted when coco- riut oil is prepared in the large way. After clearing the nut of the husk, the kernel is exposed, which is effected by breaking the shell with a crooked knife, an operation which OF THE COCO-NUT TREE. 139 is generally performed by one stroke.. The watery part of the kernel is dissipated by exposing it to the sun for a few days, during which period it acquires a considerable degree of rancidity. In this state the kernel is called copra, or copperas. The oil is extracted from copra by grinding it in a very clumsy mill, which is worked by bullocks. Oil has for some years past been extracted from copra in large quantities at Colombo, by means of the power of a steam- engine. ‘The value of copperas exported from Ceylon, in 1813, amounted to 27,9'75 rix dollars. The substance which remains after the oil has been ex- tracted from copra is called taur, os serves well to feed pigs, poultry, &c. Ceylon exports annually a great quantity of coco-nuts, chiefly to India. In 1809, the number amounted to 2,977,275. The medium price may be stated at about 3s. 6d. per hundred, or nearly one halfpenny a-piece. According to Kostrer, the value of coco-nuts in Brazil is about 5s. 6d. per hundred, or a little more than ths of a penny each. In Ceylon they pay an export duty of 5 per cent. These nuts are sometimes brought to this country from the West Indies. The captains of ships use them instead of wedges of timber, to fill up the vacua between the casks and other packages which compose their cargoes. On this account, the freightage of the nuts adds little to their original value. They are there- fore now said to be as common in the shops and streets of London as the orange. I know they may be procured in great abundance at Liverpool. Coco-nut oil may be exported from Colomba, at about 1s. Gd. per gallon; and, at this price, a large quantity is annually sent to different parts of India. In Java, where it is an article of importation, the market price 1s usually about six Spanish dollars a-picul, which is equal to about 3 140 NATURAL AND ECONOMICAL HISTORY 1s. 9d. per gallon. - Within these few years it has been imported into Great Britain, where the same quantity has been sold as high as from 5s. to 6s. The quantity exported from Ceylon, in 1813, amounted to 27,265 measures, each measure about two pints; value in rix dollars 7952. In Ceylon this oil is universally used both by Europeans and the indigenous inhabitants, as a lamp-oil. The natives burn it in a section of the coco-nut shell, or in a small earthen-ware vessel. Some of the upper ranks have brass lamps four or five feet high, which have several flat basins, with projecting beaks, affixed to a vertical stalk. The oil is introduced into the basins, the beaks of which are fur- nished with cotton-wicks. Torches are prepared in Siam, by drying elephants’ dung, soaking it in coco-nut oil, and then covering the mass with long dry leaves tied at short distances, with shreds of bamboo. The Singalese, and indeed a great proportion of the in- habitants of Asia, use considerable quantities of this oil, for the purpose of external inunction. It is not easy to ascer- tai precisely the benefits they expect to result from this practice. Some of the Orientals say, that inunction is used for the purpose of preserving their skins from the sun and wind. ‘They sometimes anoint their bodies previously to going into the bath, probably for the purpose of diminish- ing the shock they might feel by a sudden reduetion of the temperature of the skin: more commonly, however, the inunction takes place upon emerging from the water. The oil is applied with a considerable degree of friction; or, as -Damprer describes the process, “ Chafing it for half an hour into hair and skin;” and the whole surface of the body, from the crown of the head to the soles of the feet, is generally anointed. It is perhaps more frequently ap- plied to the hair of the head than to any other part of the body. I cannot, however, learn that they intend to destroy OF THE COCO-NUT TREE. 144 — vermin by this means, although, in all probability, it may have such an effect. The Asiatics, without much exception as to rank, do not seem to consider this source of disquie- tude as either uncomfortable or disgraceful. Captain Lyon, who seems to have practised the munction of oil, while in Northern Africa, says, “‘ It is very refreshing, after a long day’s journey, to be well oiled over.” Coco-nut oil is a good substitute for olive oil, in the composition of pharmaceutical preparations, such as oint- ments, plasters, &c. In the laboratory at Colombo, it is employed in a number of the preparations where olive-oil is directed to be used by the different pharmacopceias. One of the editors of the Journal de Pharmacie, says, respect- ing coco-nut oil, “ J’ai aussi observé que cette huile divi- sait mieux le mercure qu’aucune autre huile végétale.”"— (Tom. 1. p. 101.) Mixed with dammer (a species of resin) aaa the com- pound melted, a substance is formed which is much used in India to pay the seams of boats and ships, in place of pitch. “The same compound is employed to protect the corks of wine and beer bottles from the depredations of white ants. In this country, it has been employed as a lamp-oil, and in the manufacture of cloth, instead of olive-oil. ‘Soap and excellent candles are made of it; and I am mformed the glass-blowers prefer this oil to all others in their operations. Hitherto the importation of coco-nut oil into Europe has been attended with much waste by leakage, in consequence of having been imported in casks, the wood of which per- mits the contents to pass through in large quantities. Be- tween the tropics, the temperature of the cabin or cuddy of a ship, is frequently as high as from 83° to 86° Fahren. ; that of the hold must be considerably higher. Coco-nut oil does not freeze until the temperature be reduced to 73° 142 NATURAL AND ECONOMICAL HISTORY Fahren. Hence it is in a fluid condition during the greater part of the voyage from India. The shells of coco-nuts are manufactured into beads for rosaries. ‘They are also used as drinking-vessels, and for various other -domestic purposes. Occasionally they are polished by the natives, who cut figures in relief upon them. When thus ornamented, they are sometimes employed by the English as sugar-basins. In the neighbourhood of Monte Video, in South America, the ladies drink an infu- sion of an herb called matte (Paraguay tea) from highly ornamented coco-nut cups. 'They*extract the tea from thé cup by sucking it through a long silver tube. The com mon ladie used in great part of India and in the Brazils, is formed of a part of a nut, to which a long wooden handle is fixed. In America they have even given a name to the instrument, for ladles made of silver are cailed silver cocos. By the inhabitants of some of the Oriental Islands, they are employed as a measure for ascertaining the quan- tity of both dry and fluid substances. ‘Their capacity is known by the number of cowries (Cyprea moneta) they will contain. Hence there are cocos of 500 or 1900 cowries, and so on. | : They are used as fuel by the goldsmiths; and, when converted into charcoal, they are mixed with lime, and em- ployed to colour the walls of houses. As an article of the Materia medica, the natives of India recommend a decoction of the roots of the coco tree, mixed with ginger, as an excellent febrifuge. The juice expressed from young branches, combined with oil, is said to be a use- ful application to hemorrhoids. In chronic inflammation of the bladder, and gonorrhcea, they recommend a mixture of the expressed juice of the flower of the coco-tree and sugar. The oil is said to be useful, if applied to ulcers or pustules on the head. Mixed with salt, and drank to the quantity OF THE COCO-NUT TREE. 143 of eight ounces, it is said to expel worms from the intes- tines. Particular virtues have been attributed to cups made of the shell of the nut. They have been supposed to give an antiapoplectic quality to intoxicating liquors. Many other virtues are ascribed to different parts of the tree, of which it is not necessary here to take notice. When coco-nuts are intended for seed, they are placed close to one another, with the holes uppermost, and covered with a small quantity of earth. In a short time, the aque- ous fluid is absorbed, and the cavity becomes filled with a spongy-white substance. “Through the largest of the three holes the plumula passes, and sometimes along with it the radicles, which run downwards on the outside of the shell. The seedlings are allowed to remain in this state for about a year before they are transplanted. Holes of about 2 feet deep and from 25 to 30 feet distant from each other, are dug in the field intended for a coco-nut garden, and the young shoots put into them. A little earth is put round the nut; and, in dry weather, the plants are watered. They require to be protected from cattle, and particularly from elephants. 144 ON THE ORGANS OF DIGESTION, &c.

'This observation will explain the brevity of this and the’succeeding Memoirs on the anatomy of the Orni- thorynchus, for most of the internal organs, which now fall to be described, have been already submitted by him to a minute dissection. It has been already remarked, that, properly sane there 1s no ascending branch of the lower jaw in the Orni- thorynchus, instead of which there is found only a slight _ curvature; the coronoid process is small, though sufficiently distant from the condyle; and the genera! disposition of the glenoid cavity, for receiving the condyle, seemed to me such as to admit of extensive motion from before, backwards, and also horizontally. This agrees with the configuration of the mouth and palate, and with the total absence of all cutting or incisive teeth. Whatever be the food swallowed, whether insects or aquatic vegetable matter, it must be sub- mitted to a certain degree of trituration in the mouth, and, to effect this completely, is conveyed into two large bags or cheek-pouches placed on each side of the head, and the only entrance into which is between the large grinding- teeth. ‘This was essential to the existence of the animal, and results from the structure of its stomach, which, being totally without that strong cuticle and powerful muscles by which the food is triturated in birds and some other animals (as in the Myrmecophaga capensis), required that the whole of the functions of mastication, the complete tritura- tion of the food, and its reduction to a pulpy mass fit for the immediate action of the gastric juices, should be per- formed in the mouth. The cheek-pouches, situated a little behind the angles of the mouth, are capable of containing a considerable quantity of food ; they are lined by a strong cuticle, and have posteriorly a gland, which evidently pours VOL. V. K 146 ON THE ORGANS OF DIGESTION, &c. its secretions into the corresponding pouch, and must be considered as the parotid. ‘They are formed chiefly by the buccinator muscle, and are supplied by branches of the facial nerve. i | The teeth of the Ornithorynchus have generally been ~ described as four in number, that is, four large grinding- teeth, placed two in either jaw, at the entrance of the cheek-pouches: but some anatomists seem to have over- looked four narrow, horny bodies, placed over the maxil- lary bones, in the same line with the grinding-teeth, but anteriorly to them. They are about ;%ths of an inch in leneth, and ‘3th where broadest. They are composed of a horny substance, and are evidently of the same nature with the true grinding teeth: they are to be considered as corresponding to the smaller grinders of the Mammalia *. The structure of the larger grinding teeth has been con- sidered by M. Cuvier as the most extraordinary amongst quadrupeds. ‘They are said to be composed of a great number of small, straight, and parallel tubes, so that the surface of a transverse section resembles absolutely that of a bamboo-cane (jonc a canne): these tubes are not closed, and the tissue of the tooth is compact only at the triturat- ing surface: there is no large cavity in the interior of the tooth. These peculiarities in structure, described from the teeth of the Orycteropus, may readily be distinguished in the larger grinding teeth of the Ornithorynchus. These on their grinding surface were very much hollowed out, instead of being tubercular; they may be fairly considered as connected with the integuments only, since their struc- ture is so different from the teeth of all other animals, and -® Thave made no mention here of the two teeth which are implanted into the tongue, and which were described with that organ in a former memoir IN THE ORNITHORYNCHUS PARADOXUS. 147 the alveolar cavity, into which they are received, is lined throughout by the true dermis; they are simply analogous therefore to cuticle, horn, &c., and have nothing osseous in their composition. The salivary glands need not detain us long. The paro- tid has been already described. The only other salivary gland which I remarked, was the maxillary, situated on either side, over the great nerves and bloodvessels, high in the neck, and close to the lower jaw. From this there pro- ceeded a long canal passing over and through the muscles going to the tongue, and running parallel to that organ; near its termination it becomes very zigzag, and diminishes in caliber; it pierces the membrane of the mouth at the sides of the anterior portion cf the tongue, and near the union of the branches of the lower jaw-bone. These maxillary glands are large, but not remarkably dispropor- tioned to the size of the animal, as is said to be the case in the Echidna, in which animal the parotids are wanting. It could scarcely be interesting to the Society to detail the observations made on the muscles of the tongue, palate, and of those connected with the os hyotdes, as it would be but a repetition of what has been already so well described by M. Cuvier. The larynx itself is composed of the usual cartilages and muscles, sufficiently distinct ; the epiglottis and arytenoids are weil marked, and I thought the thyro- arytenoids rather strong: the glottis is formed partly by the arytenoidei cartilages, and partly by the true vocal liga- ment; between which and the superior margin of the cri- coid cartilage there is a considerable cavity or ventricle. Immediately above the vocal ligament and thyro-arytenoi- dei muscles, a small ligamentous and partly muscular cord, stretched from the base of the epiglottis to the anterior part of the arytenoid cartilages, running parallel with the true vocal cords, and immediately outside this, is a much lar- KQ 148 ON THE ORGANS OF DIGESTION, &c. ger muscular fasciculus, arising from the anterior part of the base of the epiglottis (or, anterior and superior, sup- posing the epiglottis to be laid down upon the glottis), and running parallel with the preceding, to be fixed into the base of the arytenoid cartilages. These cords cor- respond with the superior or anterior vocal ligaments of the Mammalia, and there even appeared to be a small ca- vity or ventricle situated between them and the true vocal cord. The anatomy of the stomach, intestines, and liver, was found to coincide with the details in the Anatomie Com- paréex. ‘The following table will give an idea of the pro- portional length of the intestinal canal in the Ornithoryn- chus, Echidna, and Fourmilier.

A number of dark-coloured glands are situ- ated at the base of this appendix, and betwixt its tunics. " The spleen seemed to me to be bilobular, and measured nearly 43 inches in length; it was regular as to situation. IN THE ORNITHORYNCHUS PARADOXUS. 149 The internal lamina of the small intestines is known to be very peculiar; it forms a number of circular and parallel laminz close to each other, which diminish greatly the diameter of the canal. They are so incredibly numerous, as to give to the internal lamina of the intestines an extent, which I should scarcely think to be equalled comparatively in any other animal. . These folds disappear near the ter- mination of the small intestines in the colon. The pecu- liarities in the termination of the rectum, in the structure of the cloaca, and anus, have been already noticed; the . most ample details relative to this part of the anatomy of the animal, and more particularly as regards the distribu- _tion of the suspensor muscle of the cloaca, as being more connected with a systematic work, will be found in the third volume of the Anatomie Comparée. There is little peculiar in the structure of the trachea and lungs; the cartilaginous rings of the former are incom- plete, as in the Mammalia. The trachea divides at an acute angle into two bronchial tubes, which pass imme- diately to each lung: the whole inner surface of the wind- Pipe is studded with small transparent cartilaginous bodies, like millet-seeds. A number of small glandular bodies were found close to the upper part of the trachea, and precisely in the situation of the thyroid gland, nor could any other be discovered. The elasticity of the lungs is considerable, _and the capacity of the chest shewed that the quantity of _ air taken in at each inspiration must be very great in pro- portion to the bulk of the animal. : _ here is undoubtedly something of an ornithological character in the structure of the heart; the valves placed at the entrance of the venze cave into the right auricle seemed to me in a great measure muscular; and the right auriculo-ventricular valve was much more muscular than membranous. The bloodvessels had suffered so much by 150 ON THE ORGANS OF DIGESTION, &c. maceration, that nothing could be made of this part of the dissection; the blood was every where coagulated into small, white, rounded, friable masses. The sinus placed between the liver and diaphragm, and which is known to be so large in most aquatic mammalia and in diving birds, was of considerable size in the Ornithorynchus. I need scarcely mention that the foramen ovale of the heart was closed, and that the ductus arteriosus had disappeared The delicate tendinous-looking fibres, which pass from one paries of the right ventricle to the other, have not escaped the notice of M. Cuvier. After what I have said of the strictly mammiferous character of most of the organs cle- scribed in this memoir, it may be hardly necessary to men- tion, that there existed no appearance whatever of an infe- rior larynx. The numerous lymphatic glands found in various parts of the body, shew a very completely organised system; a string of lymphatic glands exist in the lower and anterior part of the neck; they are about the size of small peas, and of a dark-red colour, occasioned probably by the spirit in which the animal had been preserved. Numerous lym- phatic glands are found likewise in the axilla, in the course of the jugular vein, and under the splenius muscle. The mesenteric glands were present, and sufficiently numerous. The accompanying drawing of the abdominal viscera, by Mr Watson, will enable the members of the Society to comprehend the general appearance and distribution of these organs. IN THE ORNITHORYNCHUS PARADOXUS. 151 Memoir IIf. On the Kidneys, Urinary Bladder, and Organs of Generation, in the Male of the Ornithoryn- chus paradoxus. Tue kidneys had suffered so much by long maceration in spirits, that they were reduced to a pulpy, homogeneous mass, which gave way under the smallest pressure. No- thing could be made of their internal structure. It is stated in the Anatomie Comparée, that the medullary portion of the kidneys in the Echidna terminates by four papillee, and that the pelvis of the kidney is confounded with the calices. Two ureters, very distinct in the Ornithorynchus, conduct the urine into a urinary bladder, thin in its parietes, but quite proportioned to the size of the animal. Air blown into the bladder by the blowpipe readily passed into the ureters, which I imagine to be rather a rare circumstance, _as I do not remember to have found it so in any other ani- mal. It is stated in the Anatomie Comparée, that the in- sertion of the ureters is placed in all animals at a certain distance from the neck of the bladder, excepting in the Echidna and Ornithorynchus, in which this insertion takes place beyond a little swelling (dourrelet), which seems to _ separate the bladder from the urethra, in such a way, that the ureters open into this latter canal, rather. than into the bladder *; nevertheless, by insertmg the blowpipe into * On slitting up the urinary bladder somewhat farther than is represented in the drawing, I do not find this to be borne out by the appearance of the parts. 152 ON THE ORGANS OF GENERATION, &c. either of the ureters, the urinary bladder may be readily distended, and will remain so, though no compression of the urethra be employed. I did not satisfactorily make out the supra-renal glands, but I am willing to ascribe this apparent exception to a very general law, to the state of the organs, which did not permit me to distinguish them from the kidneys. The dissection of the organs of generation in the male Ornithorynchus was performed with a care proportioned to the usual intricacy of the parts, and to my knowledge of the very extraordinary contradictions existing in the writings of authors of the highest merit. The errors which anatomists had committed in their descriptions of the or- gans of defence, the poison-gland and spur, I am still im- clined to consider as purely an omission on their part; for such was the distribution of the gland and duct, as exhi- bited in drawings to the Society, so easy its display, that the merest student in anatomy could, with sufficient pa- tience, have made out the structure of the whole; but every anatomist knows, that the organs of generation are, generally speaking, the most complex of the frame, and re- quire, in order to be unravelled, the most delicate dissec- tion. The result of the inquiry is as follows. The preparatory male organs, that is, the testicles, are placed in the abdomen near the kidneys, and they seemed to me to be constantly fixed there. The epididymis was proportionally large, but I could perceive nothing very remarkable in the vasa deferentia, which proceeded direct- ly, without any dilatation, but rather a slight contraction, to terminate in the urethra, close to the entrance of the urinary bladder, into the same canal. The small longitu- dinal holes, by which they open into the urethra, are di- rected upwards, so that on introducing the tube of an ANEL’s syringe into the vas deferens near the epididymis, IN THE ORNITHORYNCHUS PARADOXUS. 153 the contained fluid passed out perpendicularly upwards, and not in the direction of the vas deferens itself: a small mu- cous papilla is placed near the orifice of each vas deferens *. But previous to our proceeding farther with the description of these organs, we must revert to the more external parts, and describe the cloaca itself. It is well known that, externally, one orifice only is seen in the male ornithorynchus, which is to serve for the pas- sage of the solid and liquid excrement, and of the penis. This orifice, situated at about 44 inches from the extremity of the tail, opens into a considerable cavity, generally called the cloaca. When this cavity is slit open very carefully, we perceive three orifices of different dimensions, the uses of which are easily discovered. The highest up, which is also the largest, is the extremity of the rectum‘; the se- cond, at about ;4,ths of an inch from the ‘nian is the opening of die urinary urethra; and the third, situated close to the former, passes into a sheath, in which the penis is entirely concealed. On the surface of the cloaca, near the termination of the rectum, are five or six small dark- coloured orifices, by which a few very small glands pour their secretions into the cloaca. If the urethra be now laid open from behind, that is, on the side which regards the ® The description taken at the time of the dissection, is as follows :— *¢ These ducts open close to the entrance of the urethra into the bladder, by a narrow linear aperture, the lower edge of which forms a sort of valve.” + It is to be regretted that this name of Cloaca was adopted, taken as it is from the class of birds. The same structure exists in the beavers and hence we see evidently the impropriety of the name ‘* Monotremes,” given by some French naturalists to the Echidna and Ornithorynchus ; under which appellation, they ought also to include the Castor tribe. + The length of the cloaca, from its external orifice to the opening of the rectum, is about ] 7 oth inches. 154 ON THE ORGANS OF GENERATION, &c. rectum, and the incision extended to the urmary bladder, there will now appear a circular orifice, situated at about 1,4,th inches from the opening into the bladder, and pre- cisely 1,%,th inches from the orifices of the seminal ducts or vasa deferentia, which have been already described as entering the urethra close to the orifice of the bladder. ' The urethra itself is composed, as M. Cuvier well re- marks, of a muscular portion only, included chiefly within the pelvis, and wants that which we call vascular. Its length from the openings of the vasa deférentia to the cloaca is about 1,%th mches; it is united to the lower surface of the rectum, and inclosed with the last. by a common censtrictor muscle. A layer of muscular fibres, very strong throughout its whole extent, strengthens its pa- rietes. ‘The penis is withdrawn during its relaxed state into a particular pouch, and passes out at the time of erec- tion by an orifice formed in the lower paries of the cloaca, under that which is peculiar to the urine. It is short, ‘nearly cylindrical, and terminated on each side by two small rounded lobes corresponding with the glans penis, each in ‘a great measure covered by its respective prepuce. When this prepuce is opened, four smail conical papillae, or nip- ples, appear on the surface of either glans. ‘The surface of the penis is extremely rugose, and more particularly the anterior half; these rugosities terminate in very small coni- cal papille, which might at first sight be mistaken for small bristles. Ifthe sheath containing the penis be now slit up, the anatomy of the whole parts becomes distinct; the ori- fice on the lower surface of the urethra is proved to be the opening by which the seminal fluid passes from the com- mon urethra into the canal of the penis, destined for the transmission of the seminal flind, and that secreted by the glands of Cowper only. To make this evident, we must IN THE ORNITHORYNCHUS PARADOXUS. 155 refer to the situation of the glands of Cowper, which are placed close to the anus, outside the pelvis, and may rea- dily be discovered by removing the skin of the permeum, and the muscles by which they are closely enveloped. These glands are comparatively of very large size, a fact readily accounted for, by considering that all the other or- gans generally found in animals as appendages to the male generative organs, such as prostate, seminal vesicles, acces- sory vesicles, &c. have disappeared. ‘The duct proceeding from each of these glands is about an inch in length; they unite in a common cavity of small dimension, but distinct, placed close to the urethra, and into which enters the very short canal from the urethra, (whose orifice I have de- scribed as situated on the surface of the urethra, at about 154th inches from the entrance of the urethra into the bladder, and 1,2,th mches from the termination of the oasa deferentia m the common urethra); and from which arises the long seminal canal or urethra of the penis, a duct destined for the transmission of the seminal fluid, and which entirely escaped the notice of the French anato- mists. This duct or canal passes through the centre of the penis towards its anterior extremity, but divides, before ‘terminating, into two ducts, destined for the separate bun- dles of papillse, in which the bifurcated or double glans of the penis terminates. When the point of one of these pa- pillze is cut off, it is found to lead into a common cavity placed at the base of the small bundle of papillez, and into which enters the seminal urethra already described. I now - introduced the tube of a syringe into the open orifice of the papilla or nipple-like termination of the glans, which had been cut across, and found that the injected fluid re- turned by the orifices of the remaining papille, which had been left untouched, shewing that the resistance offered by 156 ON THE ORGANS OF GENERATION, &c. the seminal urethra contained within the body of the penis was greater than that offered by the papille themselves. When the pipe was pushed farther on, so as to enter the branch communicating with the main canal in the body of the penis, the fluid passed out most readily by a small ori- fice, which had been intentionally made in one of the ducts leading from Cowper’s glands, shewing thereby the very free and direct communication between the seminal urethra of the penis and the ducts and glands of Cowper. Having now secured the duct of Cowper, so as to prevent the fluid passing out by the artificial opening, the whole of the fluid injected into the seminal urethra by the open papilla passed readily out by the common orifice on the lower surface of the urethra, the orifice by which the seminal fluid passes from the common urethra, to that contained within the body of the penis; but the fluid passed out in such a way as shewed that it had entered a common cavity, and that — having no longer an exit by the ducts of Cowper, it became necessarily effused into the common urethra by the orifice above described. Lastly, having introduced the tube of the syringe into the orifice by which the seminal fluid passes out of the urinary urethra into the little cavity at the base of the penis, and compressing the opening around the nozzle of the tube, the fluid, whether water or quicksilver, readily passed out by all the papillz situated in either glans of the penis. The physiology of these very intricate organs becomes now exceedingly simple, and serves to throw considerable light on some of the accessory organs connected with those of generation. 'The whole of the accessory organs have disappeared, excepting the glands of Cowper,—a fact suf- ficient of itself to give an importance to these glands, which has hitherto been denied them, But they are moreover IN THE ORNITHORYNCHUS PARADOXUS. 157 connected. with the seminal canal peculiar to the penis it- self, and wholly unconnected, or nearly so, with the urinary or true urethra *. The passage and course of the seminal fluid may be readily understood : it is first poured into the common urethra, close to the bladder, by the vasa de- Jferentia ; passes along this canal, until it reaches the sur- face of the urethra placed over the base of the penis, and where the opening of the seminal urethra of the penis is placed ; the remainder of the urinary canal being shut during erection, partly by muscular contraction, and partly by the efflux of blood into the body and base of the penis, no other passage is left for the seminal fluid, but that open-. ing into the common cavity situated at the base of the penis, and into which are also poured the secretions from the glands of Cowper. But, as fluids readily pass from the ducts of these glands + into the seminal canal of the penis, and vice versa, so these secretions are readily transmitted with the seminal fluid along the seminal canal, to the four small conical papille situated on either glans, with which this animal is furnished. ‘These papille, I have already stated, are hollow, and perforated at their extremity. | The penis is about an inch in length, in its relaxed state, _ ® In most animals, the ducts of Cowper’s glands are so situated as to render it impossible for the seminal fluid to pass along these ducts towards the glands themselves. This is not absolutely the case with the same organs in the ornithorynchus, but I do not think that there arises from this the least doubt relative to the nature of these bodies called Cowper’s Glands. I be- lieve them to be essentially glandular; and not receptacles for the seminal fluid, but destined to secrete a fluid of importance in the act of generation, + By a strange oversight, the hedge-hog is stated in the Anatomie Com- parée, not to have the glands of Cowper; but the fact is, that they are res markably large in that animal, whose generative organs merit a more careful analysis than has hitherto been made. 158 ON THE ORGANS OF GENERATION, &c. but it is evident that this measurement is not to be depended on. It terminates anteriorly on either side, by four white, conical elastic papille, resembling nipples.. These may be considered as the terminating points of a double glans, though this, during the relaxed state, 1s by no means very distinct. When the penis is cut across, or opened into, it is found to possess a structure resembling the usual corpora cavernosa, and to be almost entirely composed of numerous vessels of comparatively large caliber. ‘The parietes are dense and strong. It will no doubt be expected of me, by many of the gentlemen who have done me the honour to listen to this, and to the preceding memoirs, that I should explain how the anatomy of parts apparently easily made out, should have been so singularly misunderstood by the French ana- tomists; and how, after the observations of Sir EVERARD Home, which partly coincide with the above, the same er- rors should have been repeated in the “ Regne Animal,” published so late as 1817; that is, fifteen years after the publication of Sir Everarp Homer’s observations in the Transactions of the Royal Society of London. ‘The an- swering these questions I consider as a duty I owe as well to the Society before which I read this memoir, as to the distinguished naturalist who intrusted me with the dissec- tion, and who, now for a long time, with unexampled libe- rality, has forwarded, to the utmost of his power, my re- searches into comparative anatomy. To the first question I reply, that the account of the anatomy of the organs of generation in the male Ornitho- rynchus, contaimed in the fifth volume of the Anatomie Comparéc, page 104., could not have been taken from any dissection by the immortal author of that work, but from one performed by an assistant. I shall therefore omit copying it into this memoir, well aware that it will not re- IN THE ORNITHORYNCHUS PARADOXUS. 159 appear in a second edition of the work alluded to. The following brief account, extracted from the Regne Animal, will give a sufficient idea of the extent of the error :—* The third tribe of the edentata comprises the animals which Mr Grorrroy designates by the name of “* Monotremes *,” because they have only one external opening for the seminal fluid, the urine, and other excrements. Their organs of generation present extraordinary anomalies. The vasa de- Jerentia pass into the urethra, which opens into the cloaca, at the base of the penis, which is solid, and has not even a furrow to conduct the seminal fluid +.” On examining Plate LI., contained in the fifth volume of the Anatomie Comparée, we readily perceive the cause of these errors. In Fig. 3. the common urethra is left un- opened; and the penis consequently appears without any aperture. The glands of Cowper are depicted with their ducts, but no mention is made of the mode in which they terminate, except by saying that they join the little canal - or tube by which the urethra opens into the cloaca. In Fig. 2. the urethra has been opened in such a way as to destroy the entrance of the ducts of Cowper, the cavity into which they pass, and the orifices by which this cavity communicates with the true urethra and with the penis. It is true, that these engravings refer more particularly to the Mchidna ; but we know, from the dissections of others, that these animals do not differ essentially from each other. It only remains for me to explain how these errors should have been repeated in the Regne Animal, published in 1817, and so long after better descriptions of these or- gans had been given to the world, in the Transactions of * J have already remarked on the impropriety of this name, + Tom. i. p. 224. 160 ON THE ORGANS OF GENERATION, &c. the Royal Society of London. 'The only reasons I have yet found out for this omission are, that, m these ‘* Obser- vations,” the urethra is said to open into the rectum *, which is not the case; and the two glands of Cowper are described as terminating by six or seven orifices upon the surface of the rectum, instead of which, these canals termi- nate in a small cavity which communicates with the urethra, and with the seminal canal of the penis. ‘Che anatomy and physiology of these glands have been in consequence entire- ly misunderstood ; at the same time, the true situation and anatomy.of the orifice by which the seminal fluid passes into the canal or duct of the penis, though described, is not depicted. Ina subsequent paper on the anatomy of the Ornithorynchus Hystrix, contained in the same volume of the Philosophical Transactions, most of these errors have been corrected. The true anatomy of the glands and ducts of Cowper had been discovered, and this led to a more ac- curate description of the whole: but it must be evident, that these seemingly contradictory statements might have led the French naturalists to disregard dissections which, in other respects, were extremely accurate +. I shall endeavour to submit to the Society, at a future period, a few opinions relative to the place which the Ornithorynchus is entitled to, in the scale of animals. In the mean time, it must be evident, that the speculations relative to the analogy of the Ornithorynchus with birds, so far as regards the male or- gans of generation, are entirely erroneous. ® Page 79. 1802. + I have caused drawings of the parts described in this memoir to be laid before the Society, which, in addition to the diagram, and the inspection of the parts themselves, will, I trust, render the anatomy of the whole suffi- ciently distinct. The engraving (Plate V.) is from a pencil sketch by Mr THOMSON. 3 OF THE ORNITHORYNCHUS PARADOXUS. 161 Memoir IV. On the Osseous, Muscular, and Nervous SyS< tems of the Ornithorynchus paradoxus. I expertencep the greatest difficulty in drawing up the following memoir on the bones and muscles, because it is in. these, and more particularly in the former, that the Orni- thorynchus deviates most from the usual structure of the Mammalia, and approaches nearest to the class of Reptiles. Moreover, in order to have examined the osteology of the head minutely and accurately, it was necessary to have suffered the head to macerate so long as to present all the sutures in their most distinct state. Now, this I was un- willing to risk with the single specimen in my possession. Lastly, it is evident from the state of the bones, and more particularly from the obliteration of the sutures of the cra- nium, that the animal had arrived at its full growth, and consequently was unfit, in certain respects, for the purpose of osteological inquiries. I was obliged, therefore, to content myself with a general and rather superficial view of these very important organs. From the previous description of the organs of sense, and from the skeleton which I have the honour to submit to the Society, for the inspection of the members, the general elongated form of the head will be readily understood. The extension of the superior maxillary and mtermaxillary bones is very remarkable. The zygomatic arch is broad and strong; but the osseous orbit, as in most other animals, is incomplete. The prolongation of the nares backwards: VOL. V. : L 162 OSSEOUS, MUSCULAR, AND NERVOUS SYSTEMS and the great comparative size of the superior maxillary bones, seem to me to have lessened the importance of the palate-bones in the formation of the floor of the nostrils, and to have reduced the pterygoid processes of the sphe- noidal bones to a rudimentary state, by throwimg them out _ laterally, so that they are articulated with the upper maxil- lary bones by a hinge-like joint, capable of considerable motion. They are placed horizontally; that is, on the same line with the osseous palate, and are connected with the malleus in the manner described in a former memoir. The cranium is articulated to the spinal column by two large condyles. The cervical vertebra are seven in num- ber, and thus shew a decided mammiferous character. The ailas is very large, and its processes strongly marked. The same observation may be applied to the dentata ; and, more particularly, to its spinous processes. ‘The remaining cervical vertebre gradually decrease in size: the develop- ment of these vertebrae corresponds with the great strength of the muscles which arise from, or are connected with, their processes. The total number of vertebre is forty-nine ; of which seven are cervical; seventeen strictly dorsal, having ribs implanted into them ;’one lumbar ; three sa¢ral, articu- lated with the ossa ili; and twenty-one caudal. ‘The spi- nous processes of the dorsal vertebree are much sloped to- wards the tail. ‘The four anterior dorsal vertebra have spinous processes on their interior surface, which are strong, of a square form, and gently sloped towards the neck. ‘The same processes in the last dorsal, in the lumbar, and in about one-half the caudal vertebree, are strong and vertical. In the remaining caudal vertebrae, they gradually decrease in strength, and slope towards the back. ‘The caudal vertebrze strongly resemble those of the beaver, in the length and breadth of the transverse processes, and in having spinous processes placed on their inferior surface. OF THE ORNITHORYNCHUS PARADOXUS. 163 Of the ribs, which are seventeen in number, the first is | attached to the sternum, apparently by cartilage; the suc- ceeding four by bone, the cartilage beng removed towards the centre of the rib; the succeeding ten terminate in broad osseous plates, extensively moveable, though connected with each other. Of the two remaining to be described, one is attached by ligament to the preceding mb, but they do not terminate in bony plates, and may be considered as floating ribs. There is perhaps nothing more singular in the structure of the ornithorynchus, than the formation of the clavicle and scapula, which have altogether the appearance of the. same bones in reptiles; and, as seems to me, more particu- larly in the animal called Tupinambis. From a scarcity of specimens in my possession, I am by no means prepared. _ to enter on the inquiry to which class precisely the bones composing this very complicated clavicle and scapula ought to be referred. We readily distinguish a clavicle composed of a broad flat portion, articulated with the anterior, that. is, upper edge of the sternum, and a small horizontal branch, evidently incomplete in its mesial part, and intimately con- nected with a parallel branch of the flattened portion of the clavicle *. ‘These latter branches are jomed with that por- * The fossil animal described in the Philosophical Transactions for 1818, has a sternum and clavicle very analogous to the Ornithorynchus. This analogy, which has been very beautifully pointed out by Sir E. Home and Mr Curr, is even more perfect than these gentlemen suppose; for I per- ceive, by the accompanying drawing (Phil. Trans, 1818, Part I. Plate II.) that the two small bones just described by me, as being present in the Or- nithorynchus paradoxus, have escaped their observation. Hence the distin- guishing marks between the bones composing the sternum and shoulder in these two animals does not consist in the fossil animal having a clavicular bone, which is wanting in the Ornithorynchus paradoxus, but rather in this clavicular bone or fourchette being united throughout its whole length with the scapula in the one, and with the clavicle or upper bone of the sternum 1,9 aa fe 164 OSSEOUS, MUSCULAR, AND NERVOUS SYSTEMS tion of the scapula which, from a very obvious analogy, I should call its acromial process. ‘The scapula itself is shaped hike that of a bird ; and, in addition to its acromial process, by which it is connected to the clavicle, sends a very strong process backwards and inwards, towards the upper bone of the sternum, with which it is articulated: and it is even somewhat connected with the bone which I have called the flat portion of the clavicle. Along the whole inner margin of the process of the scapula joming the sternum (and which bears so great a resemblance to the true clavicle in birds), is placed a thin flat semicircular plate of bone, which, run- ning up behind the broad clavicular bone, performs exten- sive circular motions during the action of the anterior ex- tremities, as well by reason of the laxity of its connection with the clavicular bones, as by its loose hinge-like joint with the scapula. It is exceedingly difficult to decide on a name for this very singular bone, and to trace its analogies throughout the range of vertebral animals. In the mean time, until that be satisfactorily done, it must be evident, I think, to all, that its analogies ought to be sought for in the class of Reptiles: for, in most species of this class, there would seem to prevail an analogous structure, though occasionally very complex, and with difficulty to be made out. ‘The extreme laxity of the articulation of the scapula. in the Ornithorynchus, and its anomalous bone or process, in the other. ‘There are several other differences sufficiently remarkable. The peculiar flat semicircular bone forms a great portion of the glenoidal cavity in the fossil animal, and the scapula does not seem to be in any way articulated with the sternum, unless we consider the bone marked 6 (see the drawing) as the anterior bone of the sternum. Neither of these cir- cumstances holds with regard to the Ornithorynchus paradoxus. ‘There is a considerable resemblance between the shoulder-bones of the fossil animal and the common Chameleon, a skeleton of which I have placed before the Society. a ’ Q a OF THE ORNITHORYNCHUS PARADOXUS. 165 explain sufficiently its functions; for, by this, the humeral part of either extremities is enabled to approach the other ; and thus the whole of the anterior extremities can approxi- mate much more than if the articulation of the lower pro- cess of the scapula had been attached to the sternum with the same degree of fixity as the upper or acromial process. In addition to the extensive rotatory motion which the dis- tance of the acromion from the joint enables the humerus, and consequently the extremity, to perform, another kind of motion is performed, by means of a moveable articula- tion, found only in reptiles and fishes; I mean the sliding semicircular motion performed by the squamous part of the scapula upon the flattened portion of the clavicle *. Some exceedingly ingenious attempts have been made to reduce the whole assemblage of bones composing the shoulder, ciavicle, and sternum of the ornithorynchus to their analogous bones in birds and reptiles, but these at- tempts have not as yet been very successful, and the rea- son of this appears to be sufficiently obvious; for the bones of the sternum in reptiles are in general so anomalous as to defy classification, founded on analogy with other vertebral animals ; whilst the analogies endeavoured to be established between the same parts in birds, and the mammaliia, are by no means generally agreed to. In the ornithorynchus, we find, as it were, a compound of the three classes Mammalia, Aves and Reptilia. The dorsal part of the scapula re- sembles the same part in birds. The acromia! process ap- proaches that of the Mammalia; the glenoid cavity of the joint is placed at the union of the dorsal part of the sca- pula and the process extending to the sternum, which pro- * In Plate V., will be found an accurate sketch of the assemblage of bones composing the shoulder and sternum of the Ornithorynchus, accom- panied by one of the fossil animal alluded to in the text. 166 OSSEOUS, MUSCULAR, AND NERVOUS SYSTEMS cess bears a close resemblance to the clavicle in birds; whilst the bones I have called Clavicle (three in number) are very analogous to the fork or merry-thought found in the same class of animals. With regard to the flat, moving, squamous bones situated behind the clavicle, and fixed to the sternal portion of the scapula, it is evident that their analogy is to be found only amongst reptiles. ~ Perhaps, then, we might say, that the scapula has a dorsal plate and acromial and coracoid processes; that the acromial is to- lerably regular as to situation and distribution, but that the coracoid, which, in Man, is rudimentary, 1s, in the Or-. nithorynchus, extended to the sternum*. We may next suppose the flat and broad portion of what I have hitherto called the clavicle, to be actually the anterior bone of the sternum; which, in this view, would come to be composed of five instead of three bones, placed the one immediately behind the other, whilst the two thin and long bones firmly united to the anterior extremities of them, might be considered as analogous to the merry-thought in birds f. But there still remain to be accounted for, the osseous squamous plates, articulated with what I have just called the coracoid process of the scapula, and which M. St. H1- LATRE considers as analogous to a small process of bone found immediately at the base of the true clavicle in birds, and to * I ought to mention here, that that most excellent naturalist, M. Gror- rroy St Hinarre, considers the bone we call Clavicle in birds, as the cora- coid process of the scapula; which idea is very beautifully supported by the form of the scapula in the Ornithorynchus. + The fourth of these, counting from the epigastrium, is constantly di- vided into two in the Ornithorynchus. + These are considered by M. Grorrroy as the acromial processes of the scapula greatly elongated. It is to be remarked, however, that they are con- nected to the scapula not by bone, but by a very perfect moveable articula- tion, with a capsule,-and I am not sure that M. Grorrroy is aware of this fact. OF THE ORNITHORYNCHUS PARADOXUS. 167 which he has given the name.of ‘ Os Episternal.” The principal distinguishing characteristic of this ‘‘ os episternal,” is said to be, that it is placed always on the coracoid pro- cess; but this rule does not seem to hold true with regard to the frog, and perhaps with some other reptiles. We are compelled, therefore, to consider these bones as strictly belonging to the class Reptiles, and that. their presence in the Ornithorynchus may depend either on the extraordinary anomalies which undoubtedly exist in this animal, or that it is connected with the aquatic habits of the animal, and intended to facilitate the movements of the anterior extre- ‘mity, and to extend them so far as was consistent with the safety of the shoulder-jomt. In short, it seems intended to permit the coracoid process of the scapula considerably to change its position, and to approximate or recede from its _ fellow, at the will of the animal, and thereby very much to extend the movements of the anterior extremity, and to con- _vert it into an oar of the most perfect description. It is sufficiently curious, that, whilst so much has been- written to prove the analogy of the bones entering into the composition of the sternum, clavicle, and scapula through- out the animal kingdom, no attempt, so far as I know, has been made to name the bones which may be supposed ana- logous to the marsupial bones of the pelvis, and which are not peculiar to the ornithorynchus, but found in a very con- siderable number of animals *. The truth is, that these bones are quite ‘peculiar to the class, and created by Na- ture apparently for a particular purpose, viz. of supporting the marsupium, or abdominal pouch, in which the young -of these animals are contained, from the period of their imperfect birth, until they are capable of providing tor * Since writing the above, I find that an attempt has been made to com- pare the marsupial bones with the os peniale found in certain animals, as the 168 OSSEOUS, MUSCULAR, AND NERVOUS SYSTEMS their own wants and safety. Yet these bones are present in the Ornithorynchus and Echidna, which are said not to have a marsupium ; and the fact has been brought forward by Professor BLuMENBACH, as a proof of what he calls an “union of the teleological and mechanical principles in the function of generation,—principles which were formerly thought to be incompatible with each other.” The forma- tion of this anomalous pair of bones (he observes) for the purpose of supporting the abdominal pouch of the female, is a clear instance of the teleological principle; that is, it shews a peculiar part formed for a certain purpose. Their existence in the male (and of course in the Ornithorynchus) where the end and purpose of their formation do not exist, shews the mechanical principle, as if they had been merely framed in compliance with some general model for the structure of the species *. The bones of the extremities may be described together, as they so much resemble each other. ‘The os humeri is — strong, and peculiarly formed with regard to its processes, which are very prominent, and afford a powerful point of attachment to the various muscles; it is perforated near its radial extremity, as in many other animals, for the trans- mission of bloodvessels. ‘The olecranon of the ulna is much developed, and of considerable breadth. In the posterior extremity, the fibula bears a strong resemblance to the ulna, and has a remarkably strong process for the insertion of muscles extending upwards towards the pelvis and tail. The tarsal and metatarsal and digital bones of the posterior extremities, and the corresponding bones of the anterior extremity, do not require any particular description. We shall therefore only remark, that, in the construction and perfect organisation of the bones of the extremities, the Orni- thorynchus differs most remarkably from Birds and Reptiles. eco # A Short System of Comparative Anatomy, p. 41. OF THE ORNITHORYNCHUS PARADOXUS.’ 166 I intend saying but little on the muscular system, be- cause the muscles being simply the moving powers of the bones, an inspection of the skeleton will readily explain any peculiarities which may exist in the former. The muscles situated on the neck, connecting the head, trunk, and cervical vertebrae, are very powerful, and seemed “to me regular. ‘Those of the back and tail are distributed much as in the Beaver. The marsupial bones have two muscles connected with them, which proceed from their whole inner edge upwards towards the sternum: these may be considered as analogous to the pyramidales in man. The recti, and other abdominal muscles, are present, and regular. The pectoral muscles, which are divided into two, arise from the whole upper edge and mesial line of the complex clavicles, and from the linea alba of the abdomen, nearly as low as the pubis: these muscles are inserted se- parately into the h umerus; the superior or anterior one is perforated by a strong muscle (the deltoid), arising from the dorsum and acromial process of the scapula, to be in- -serted into the os humeri. When the external pectcral muscles are removed, two broad muscles are found immediately beneath, arising from the whole surface of the peculiar squamous bone (described at considerable length above, under the name of the Squa- mous Process of the Scapula ;) and inserted the one into the mmner tuberosity of the os humeri; the other into the same bone, but much nearer the fore-arm. These may be con- sidered as analogous to the coraco-brachialis of the Mam- malia; or we may prefer giving the name of Coraco-brachia- ~ lis to two long muscles of a rounded form, which arise from the coracoid process itself, and are inserted into the os hu- mert. From the same squamous bone, and from the semi- civeular edge of the peculiar clavicle, arises a long slip of mae, which, proceeding downwards, is inserted into the 170 OSSEOUS, MUSCULAR, AND NERVOUS SYSTEMS aponeurosis covering the rectus muscle, nearly midway be- twixt the sternum and pubes. Another short but powerful muscle arises from the whole inner surface of the squamous process of the scapula, and is inserted most extensively into the broad imner surface of the os humeri; and close to it is a muscle having a similar origin, but is inserted into the first rib*. The muscles con- necting the dorsal portion of the scapula with the spine, and the former with the os humeri, are tolerably regular, and at least as numerous as in any of the Mammalia. The extensors of the fore-arm seemed to me powerful: the same observation is applicable to the other muscles of the fore- arm and leg, the extent and nature of whose motions may be judged of, by observing the bones, and, more particu- larly, the development of the radius and tibia. The sterno-mastoid is fixed into the small horizontal bone, which M. Grorrnroy calls the acromial process, and into the horizontal branch of the clavicle immediately con- nected with it. It thus becomes either a sterno-mastoid, cleido-mastoid, or scapulo-mastoid muscle, according to the view adopted relative to these bones: at the same time, the omo-hyoideus, which is much more developed proportion- ally than in the human subject, arises from the scapula, close to where it 1s connected with the horizontal branch of the clavicle, and followimg the regular course of the muscle is inserted into the os hyoides. ; These are all the details relative to the muscles with which I have thought fit to trouble the Society. The brief account I propose giving the Society of the Nervous System, cannot be expected to be either minute * From the number and strength of the muscles connected with this anomalous bone, may be judged its importance in the movements of the shoulder, and its influence even over the thorax itself.

I have-not the least doubt of their being quite regu- lar in their distribution. The fifth has been already de- scribed, whilst speaking of the organs of touch and taste. The auditory nerve was not seen; the facial, which I pre- fer calling by the name of the portio dura of the seventh pair, to any other yet invented, was regular as to its pre- ‘sence and size. Its distribution was chiefly to the cheek- pouches, and back and side of the head, around the exter- nal orifice of the ears; but it did not approach the nostrils, for a very obvious anatomical reason, and, consequently, in this animal at least, has nothing to do with the organs of respiration. The eighth, or par vagum, the ninth, with the nerve called the descendens noni, the spinal accessory, and the cervical portion of the sympathetic nerve, were very strictly as in the Mammalia. I also remarked, that the sympathetic nerve, in its passage down the neck, was more distinctly marked and detached from the par vagum, than in many animals supposed to stand much higher in the scale of the animal creation. The superior cervical ganglion was very small, but at this point the sympathetic branch united with the par vagum. Immediately above ‘this union the nerves were again distinct, and three branches belonging to the sympathetic nerve could be traced proceeding towards the fifth pair. The inferior cer- vical ganglion was large, but there did not exist any middle one. ‘The cervical nerves were large and regular. No- 172 OSSEOUS, MUSCULAR, AND NERVOUS SYSTEMS thing struck me more forcibly than this strict accordance of hie nervous system with that of the Mammalia in gene- ral: the same observation is applicable to the bones and mus- cles, so that the analogy supposed to exist between the Or- nithorynchus and Birds is reduced to the resemblance of the ossicula of the ear, and to the female organs of generation, which I have not as yet had an opportunity of examining. I could easily have swelled out these memoirs to a much greater length, by entering into the minute anatomical details, which were carefully taken down during the dis- section; but I cannot think that these would in the least interest the Society, since they do not lead to any general physiological results.

By Mr Joun Corpstream. (Read 14th July 1823.) 2 "Tue best and most valuable plan for the keeping of a thermometrical register, would undoubtedly be, to make observations at the end of short and regular intervals; for instance, every hour, or every two hours: because, the first and main object of the meteorologist, in keeping such registers, bemg to ascertain the average temperature of each day, as nearly as possible, it is evident, he cannot fix this point better, than by calculating the mean of very frequent observations, which will, of course, always ap- proach nearer and nearer to the true average temperature of the whole twenty-four hours, in proportion to the nuim- ber of observations. However desirable the s csanile siecle of such a plan might be, yet its inconvenience, nay, general impracticabi- lity, is abundantly obvious. 176 METEOROLOGICAL OBSERVATIONS It becomes, therefore, a2 matter of no small moment, to find out, at what hour or hours, the average temperature of the day, for the most part, occurs; that the meteorologist may be furnished with accurate information, for the proper conducting of his observations, and a long-agitated question in physical science, finally answered. During those ages which immediately followed the in- vention of the He aletoe philosophers were guided by mere whim and caprice, in settling their hours for observing the indications of that instrument. But, since the great subject of the mean temperature of the globe has been started for discussion, and since the high importance of meteorological registrations to the best interests of mankind has been generally acknowledged, men of science have all agreed in admitting the necessity there is for thetr observa- tions being at least synchronous one with the other. This is, however, not sufficient for the purposes of philosophy. If the mean temperature of the day is not ascertained by all, the synchronism of the observations matters but little. Many different hours have been proposed as the best suited for the attainment of the object desired, but perhaps too fre- quently on unstable grounds. After the maximum and mi- nimum thermometers had deservedly come into general use, the hours of 10 a. m. and 10 p. m. were confidently stated as the preferable ones for observation; the mean of these agreeing with the mean of the extremes indicated by the instruments alluded to; that, again, being supposed by many, palpably to demonstrate the true average temperature of the twenty-four hours. The only mode, however, that can be adopted, defini- tively to settle the disputed point, plainly is, to make a continued series of observations for a considerable period of time, at the lapse of very short intervals,—as for two or three years, at the end of every half hour, day and night,— MADE HOURLY AT LEITH. Te a task that might be accomplished, in particular situations, _ by the co-operation of many, although it never could be done by a single individual. As far as our information extends, a prolonged series of this kind has never been instituted in Britain ; but it is pro- posed, at present, to give an account of such a set of obser- vations, on a small scale, lately carried on m Leith, and which have been productive of results, that prove well the in-~ terest and importance of the subject. In the twelfth number of the Edinburgh Philosophical Journal, Dr Brewster, at the conclusion of some remarks on a set of like observations carried on by Dr Dewey, at Wiiliamston, in the United States of America, mentioned, that “ it would be desirable to possess a series of observa- tions made in. Scotland for every hour of the day, for a small number of days;” and that ‘“ he begged leave ear- nestly to suggest such a series of experiments, to some of those active meteorologists who have undertaken to keep regular registers of the thermometer in Scotland *.” Immediately on reading the above quoted suggestion, I set about a series of hourly observations, and continued them for six successive days, beginning on the Ist April 1822. Not being so well satisfied with the manner in which this series was conducted, I take no notice at present of the results obtained. Soon after, I began those observa- tions which form the subject of the present communication. I proposed to myself to observe the thermometer for twenty-four successive hours every month, commencing on _ the lst July, and this plan, with the occasional assistance of a friend, I continued regularly throughout the year. The following is a copy of the journal of this series. * It appears from the notice of Dr Dewey’s paper, here alluded to, that | he observed for thirty days, at different times of the year, twenty-four times | a-day.

In domg so, I propose to use the mean MADE HOURLY AT LEITH. 185 temperature of the whole observations, as derived by the last mentioned plan, for the general standard of comparison.

From what has been already recorded, it appears, finally, First, 'That no single hour approaches, more nearly, in its temperature, to the true average temperature of the day, than does eight in the morning, or eight in the even- ing, (for, according to the preceding calculations, their temperatures seem to be exactly the same). The difference -between the true mean of the day, and the temperature at eight o'clock, was about ,°,4, of a degree. ‘* Hours proposed by Dr Dewey, + Hours proposed by the Philosophical Society of New-York, Hours which I myself found to approach nearer, in their mean tem- perature, than any other three hours, to the average temperature of the day. 186 METEOROLOGICAL OBSERVATIONS. Secondly, That the mean of the maxima and minima differs ,°6, from the average of the twenty-four hours. (The mean of the means of the maxima and minima which occurred during the series was 49°.28 varying only 555 from the standard of comparison.) Thirdly, That of the averages of the temperatures of two hours, those of 5 a.m. and 5 p. Mm. noon and midnight, 11 a.m. and 11 v.m., 10 a.m. and 10. m. approach nearest to the mean of the day. ‘The average of 5 and 5, differing from it only 1940 of a degree; of 12 and 12, vo of 11 and 11, 3, ; of 10 and 10, }. Fourthly, That of the averages of the temperatures of three hours, those of 7 a. M., 1 vp. m. and 10 Pp. M., ap- proximate most closely to the average of the whole twenty- four, the mean of the former differing ,1, from the latter. Fifthly, Of all the combinations of hours I tried, none gave the true mean temperature of the day so well as the mean of 5 a.m. 10 a. mM. 3p. M. and 10 Pp.

Such are the simple facts regarding the most important results to be obtained from this series of observations :—I abstain from farther remarks at present, and shall now con- clude by mentioning the other results, less important, de- rived from the same source. 1. At an average, the maximum of temperature occurred at 4 p. M. and the minimum at 5 a. Mo. 2. The average daily range was 9.93, its maximum be- ing 23°, which happened in August. Its minimum 5° in February. 3. The temperatures of 7 a. m. and 10 P. m. were ex- actly the same. LEITH, July 1828. X—WNotice of a“ Journal of a Voyage from Rio de Janeiro to the Coast of Peru, by Mr Wi1- LIAM JAMESON, Surgeon, Corresponding Mem- ber of the Wernertian Natural History Society.” By G A. Wanker Aryort, Esq. A. M. F.R.S. E. M.W.S5., &c. (Read 26th April 1823.) ee On the evening,” says Mr Jameson, “ of the 9th March 1822, we re-embarked on board the Fifeshire Pac- ket, having determined to go to sea early the following morning. At 4 o'clock a. M. we accordingly got under- weigh, and proceeded down the harbour of Rio de Janeiro. At 7, the land-breeze having failed, and the tide setting against us, we were obliged to anchor abreast of Porto Fogo Bay. At 10, the sea-breeze having, as usual, com- menced, we again got under-weigh, and cleared the entrance of the harbour, after making several short tacks. Wind ESE. At 4. m. passed Round Island. Evening, light variable winds, occasionally calm.” On the 20th, having reached Lat. 85° 23’, and Long. 51° 20’, Mr Jameson appears to have commenced obser- vations, which he continued during the voyage, once a day, on the temperature of the sea; and at 10 in the morning, and the same hour in the evening, on that of the air. The hygrometer (LEsiiz’s) was not forgot. Of the states of these, a very neat table is given at the close of the Journal. On the 26th, they “ passed many floating bunches of Fucus giganteus,” (Macrocystis pyrifera of AGArpny’s 188 JOURNAL OF A VOYAGE FROM RIO DE Species Algarum); several Albatrosses (Diomedea exulans) were also seen. Lat. 39° 20’, Long. 54° 13’. On the 27th, “‘ Moderate breezes from NE., with clear weather. Passed considerable quantities of Fucus gigan- teus*.

Strong westerly breeze, with a clear and cloud- less sky. ‘The surface of the sea presents the same appear- ance as yesterday ; and, indeed, the existence of a current | from the southward is evinced, lst, By the daily and pro- gressive difference of longitude, as afforded by the daily. range and chronometers; 2d, By the sudden diminution in the temperature of the water, being no less than 23°, and, lastly, By the very great quantities of floatmg Fucus gi- ganteus, which vegetates only in high southern latitudes. The influence of the current is not felt beyond the parallel of 40° S., for it is there checked in its progress by the coast of Paraguay extending NW. and SE., as well as by an opposite current flowing from the entrance to the Rio.de la Plata. A new impulse is thus communicated, which will occasion the current to take a westerly direction. “< Temperature of the ocean 53°, air 59°, hygrometer 14°.5.

A “light air from the NNE., with a clear atmo- sphere. Sea very smooth, and teeming with vast numbers of a species of cancer (Asiacus), of a dark-red colour, and about an inch in length. ‘This remarkable appearance we observed for about an hour, the vessel sailing at the rate. of two knots.” Lat. 52° 25’. Long. 64° 9’... Mr Jameson has added on the margin of his journal a sketch of this species of Cancer,.from which, if correct, it appears to: have only six legs: in this respect it differs essentially, not. only from the reduced genus Cancer of Luacu, but from every division and genus in the order Macroura of the subclass Malacostraca in the Annulose. All the known divisions of the Macroura have at least ten legs: to this: order it must, however, certainly be referred, its tail being furnished with appendices at the extremity. On the 7th, “ At 8a. m., Cape St John, the most east-. erly pomt of Staten Island, bore SSE., distant 15’. The northern coast of this island, about New Year's Harbour, is very mountainous, with peaked summits. Although late m the season, no trace of snow could be observed; and in- deed, the sides of the mountains exhibited in many places. 190 JOURNAL OF A VOYAGE FROM RIO DE an appearance of verdure.”-—‘‘ A strong current appears to set round the east point of Staten Island, the sea being very turbulent and broken.” Several penguins, Cape pi- geons, and fulmars, were seen. On the 13th, Lat. 57° 57’, Long. 64° 43’, he remarks, that ‘ two species of the petrel tribe, Procellaria glacialis and Pr. » were very common: the former is well known; but the latter is seldom, I believe, seen in the At- lantic Ocean beyond the parallel of 30° 8.” We have to regret that the species is not mentioned. On the 22d, 23d, 24th, 26th, and 28th, they experi- enced occasional showers of snow: this was betwixt Lat. 58° and 56°. On the 28th a luminous meteor was observed at the mast head, and much lightning in the SW. May 8th. Lat. 38° 24’, Long. 83° 34’, they were again surrounded by numbers of the oceanic birds (Procellaria). On the 11th, they passed about 20 miles to the west of the little island of Massafuero, to the north of which they reached about half a degree the next day. Here Mr JAMESON remarks, that “ those birds named Cape Pigeons (Procellaria) begin to diminish in number.” On the 16th, Lat. 27° 53’, Long. '75° 35’, they saw some sea-weed, and a few birds, ‘ probably of the genus Pelecanus.” On the 18th, Lat. 24° 47’, Long. 73° 36’, they passed some “ floating patches of Mucus.” Several small birds (Procellarie), flying-fish (Exocetus volitans), and a small species of the cuttle-fish (Sepia), were observed. * 20th. Light SE. breeze, and cloudy. This morning we had a nearer view of the coast. Its surface is very ir- regular, without the least appearance of vegetation. A very high mountain, named Morro de Mexillones, rises to a great elevation. A few altitudes of the sun’s lower limb, with the corresponding times, as indicated by the chrono- meters, gave for their mean longitude 70° 38’ 4” W., a very near approximation to the true place of the ship. JANEIRO TO THE COAST OF PERU. 191 At 12, Lat. by observation 22° 54’ S. Temperature of the sea 68°.5. At 4 o'clock pv. m., being about 12 miles to the NW.., the colour of the sea had changed from a dark-blue to a bottle-green. Temperature 65°, a difference of $°.5, distance from the coast about 20 miles. At 4, altered our course to NE., with the intention of entering the port of Cobijo. At 8 p. m. hove to about three leagues distance from the coast. Evening clear. ‘Temperature of the air at 10 v. m. 66°.5, hygrometer 21°.” We should remark, in addition to this outline, that Mr Jameson has added two tables at the end of his journal : one of these, we have already said, is metecrological, con- taining the state of the thermometer in the air at 10 morn- ing and evening, and the temperature of the sea. This last, he observes in an accompanying letter to Professor JAMESON, was daily ascertained at 12 o’clock, in the usual way, by immersing a thermometer in a bucket of water fresh-drawn. In this table the humidity of the atmosphere is also noted, as observed at 10 morning and evening ; “‘ this was determined by two delicate centigrade thermo- “meters, each degree of which is divided decimally; and the differences betwixt the dry and humid bulb exposed freely to the air, were daily registered.” The state of the weather and the wind, as well as the latitudes and longitudes, are also inserted in this first table. | The second shews the daily differences and rates of three chronometers kept by Mr Jameson himself on board the packet. In one column are the differences between Brown’s. and Barraun’s chronometers, in another between Brown’s and Grant’s, and in another between Barravp’s and Grant's: thus the relative rates of each could be ascer- tained without great difficulty. Mr Jamzson also gives ‘here the mean temperature of each day, in case that should affect the instruments. These tables we here insert. 192 JOURNAL OF A VOYAGE FROM RIO DE Merxorotocicat Journat from the Mouth of the Rio de la Plata, to the Coast of Peru. LEsLIE’s Hyero- METER. 10 | 10 | Daily A. M.| P.

He writes, that they are specimens of all that he could collect at Rio de Janeiro. This he, however, adds, was probably owing to his being obliged to limit his walks within a few miles of the capital. It is a district hitherto little examined for the Cryptogamic department of Botany ; and, therefore, as might have been anticipated, there are some new species in the packet. We have to regret, that the imperfect state of some of them renders full descriptions impossible. We have, how- ever, endeavoured to give such as we hope may serve in future to distinguish the plant. : . LYCOPODINEZ. 1. Lycopodium rupestre, Lr. Var.

OF THE NATIVE RACES XI.—Inquiry into the Origin and Characteristic Differences of the Native Races inhabiting the Extra-tropical Part of Southern Africa. By Rosert Knox, M.D. Member of the Wernerian Natural History Society, and of the Medico-Chirurgical Society of Edinburgh. (Read 19th April 1823.) —Se Tue best apology I can offer for attempting the Inquiry I have now the honour to lay before the Society, is, that no similar one, relative to the country I speak of, has ever been instituted. Many travellers have described, with a minuteness proportioned to their talent for observation, the Peninsula of Southern Africa, and have given to the world valuable works on its natural history, political relations, &c.; but, so far as I know, none has ever viewed the savage races inhabiting this Peninsula in an anatomical point of view, and hence have arisen ill-founded conjectures, and positive errors, too numerous to be criticised. I have en- deavoured to correct those more immediately connected with our inquiry, but have carefully avoided general cri- ticism, as leading me from the subject. The Society will INHABITING PART OF SOUTHERN AFRICA. 207 readily imagine the difficulties I experienced in avoiding frequent conjecture, and the impossibility of doing so alto- gether; but recourse has been had to conjecture rarely, and, though some of the conclusions may, from insufficient data, or other causes, prove erroneous, I shall still feel suf- ficiently recompensed for my labour, should the facts I have collected be found serviceable to those engaged in writing the Natural History of Man. The part of Africa situated to the south of the Tropic, contains at least three distinct races of men. ‘Those met with in proceeding from Cape Point northerly, are intru- ders; they constitute the Anglo-Dutch colony of the Cape, and are a mixture of almost all the modern nations of Ku- rope, the Dutch preponderating. The colonists dwelling in the remoter districts attain a gigantic size, owing, no doubt, to their descent from a race naturally tall; and mm perfecting which, as to stature, much has been effected by climate, food, and other localities. ‘This race, at present, extends from Cape Point northward to the banks of the Gariep, or Orange River, and eastward as far as the Keis- kamma River. They have pushed before them, and partly exterminated, the race of Hottentots, or Bosjeman (for I shall consider them as the same), who are now found only in small numbers, either as servants to the colonists, or still preserving a sort of savage independence in that vast tract of almost desert country, extending from the chain of mountains out of which the Gariep and Great Kei rivers rise, westward to the shores of the Southern Atlantic. On the verge of the Tropic, and close to the western shore, the Damaras are found (a Negro race, as I have been assured), who extend towards Benguela and Congo; so that the Bosjeman race, if they exist much to the north of the Gariep River, must occupy a central stripe of Africa, 208 ON THE ORIGIN, &c. OF THE NATIVE RACES bounded, on one hand, by the Damara and Benguela coun- tries, and, on the other, by the Kaffer nations. These latter extend from the Keiskamma eastward along the coast towards Inhambane; but previous to reaching this point, they become inland, and possess the mountain- country, which, there is every reason to suppose, may eX- tend from the sources of the Gariep and Great Kei rivers, to the Equator. It would appear from the Journal of Van REENEN, that the Temboo is the last of the Kaffre tribes found on the coast of Natal, and that beyond them, in about Lat. 26° S., are found the Hamboonas, a race totally different from the Kaffres. They are thus de- scribed: ‘Ce peuple a la peau jaunatre avec de longs che- veux fort epais et frisés, qui sont relevés sur le sommet de la téte en forme de turban*.” At the point of coast where the Hamboonas disappear, the Negro race commences, and, extending around Sofala, Inhambane, and Mozambique, furnish the Portuguese with the most ample means of car- rying on a traffic the most revolting to the feelings of man- kind. The mountain-country, inhabited by the Kaffre race, cannot be of any great breadth, limited as it is on the east by the Negro country of Mozambique, and to the west by the vast and unknown deserts supposed to be in- habited by the wandering Macasses. It is unfortunate for our present inquiry, that two geographical problems of much interest remain to be solved. The Kaffre races have been conjectured to be Arabian, and the Bosjeman tribes have been considered by some of Chinese origin, by others * I consider the Hamboonas (if they really exist) as descended from a race of shipwrecked Chinese or Malay mariners, modified by intermarriage with Negro or Kaffre tribes. It is, however, quite possible that they may he a race from Madagascar. | INHABITING PART OF SOUTHERN AFRICA. 209 of Egyptian; they have even been compared to the Tro- glodytes or Pygmies of Heroporus, that dwelt in the de- serts to the south of Barca and Syrene. We shall presently see that the Kaffres are not Bedouin Arabs, and, moreover, that they cannot be traced to any European or Caucasian stock ; but the question of origin, as regarding the Bosje- man, is of far more difficult solution. It were highly de- sirable, as well for geographical science as for the natural history of Man, that the extent of country occupied by the Kaffre race, from the Keiskamma northwards and east- wards,—in other words, the boundaries of Kaffraria Proper, -——-were correctly ascertained. We know that the race ex- tends on either side the mountain-country stretching from the sources of the Gariep towards the Equator, inhabiting the valleys and slopes of the mountains: their progress westward was probably arrested by the existence of great central deserts, and by their natural dislike to such coun- tries; whilst eastward, that is, towards the Indian Ocean, numerous Negro tribes were im possession of the country. That they have long been an imland race, is evident from their total ignorance of the use of boats or canoes: more: over, the Portuguese, in their ardent search after gold, re- ceived some severe checks from the black races inhabiting the mountains to the westward of their settlements: now, it is probable that these were Kaffre tribes, for Negroes are naturally timid, and easily subdued. It is much more difficult to guess with any shew of pro- bability at the extent of the Bosjeman nations, partly from their total dissumilarity to all surrounding tribes, and partly from the extremely defective state of our knowledge rela- tive to the geography of Central Africa. It is well known that they originally extended to Cape Point, and have been found to the northward as far as Europeans have yet pene- trated. Beyond this all is profound obscurity: How, then, VOL. V. O 210 ON THE ORIGIN, &c. OF THE NATIVE RACES are the aborigines of Southern Africa to be traced to the primitive races of the ancient world? In the absence of all historical detail relative to the affiliation of these races, and until some future Park shall make us acquainted with Central Africa, as well to the south as to the north of the Line, both being equally unknown, we shall bring together the results presented by anatomical inquiry, which, being a method founded on fixed and general physical laws, will, if it attain not the truth, at least approximate to it. We may view the human race as derived originally from one stock, to which the arbitrary name of Caucasian has been given. This species, influenced by chmate and civiliza- tion, assumed, at a very early period, five distinct forms, which have also been arbitrarily designated by the names of Caucasian, Mongolic, Ethiopian, American, and Malay *. We cannot hesitate referring the Kaffre nations to the Ethiopian, not so much from their position, as from their close resemblance; whilst the Bosjeman may be arranged, for the present, with the Mongolic, until further investiga- tion shall have shewn a more intimate relation with some unknown African tribes, or until the race shall have been fairly traced through Central Africa to the Valley of the * I shall here take the liberty of remarking,. that the Malay race seems to me an artificial variety, and has no existence in nature as a distinct race of men. I am inclined to refer the whole inhabitants of the innumerable islands scattered over the Great South Sea (including New Holland) to the American variety. In Southern India they have mixed with the Mongolie and Caucasian races, and form consequently a mixed or mulatto breed; but they may be traced tolerably pure as high as Sumatra, in which island seve- ral tribes are found much resembling the native Americans, and retaining all their customs, even to the pretended flattening of the head by artificial means. It is probable that in this race only are found the anthropophagous tribes. ih Wes oie Se PLATE VIL.

OF THE NATIVE RACES The cranium of the Kaffre is inferior in most of its mea- surements to the European. The temporal bones are flat and compressed, and the squamous suture often straight, instead of being semicircular, as in the European *. ‘They are nice in the choice of their food, and reject fish, fowls, and generally whatever by the Levitical law is deemed un- clean; yet they eat the mner parts of animals, as the in- testines, stomach, lungs, &¢. raw, torn from the animal just dead. : From a careful consideration of the habits and configu- ration of this race, I believe them to be closely allied to the Negro, and that the observable differences are attributable to the different climates they inhabit. The Kaffres, in a word, are the Negroes of the mountains; they are Negroes changed by inhabiting an extra-tropical climate; like all mountaineers, they are hardy, bold, and fond of liberty. In intellect they are superior to the Negro, and I believe them capable of a very considerable degree of civilization. The remarkable disproportion observable between the up- per and lower extremities of the Kaffre + may, perhaps, be owing to the very unequal degree of exertion to which these separate parts of the body are exposed. The Kaffre never labours, and hence his arms are weak; but he is strongly exercised in the chase and in predatory excursions, -by which means his limbs become muscular, and occasion- ® Some Kaffre skulls have been shewn me, in which the malar bones were remarkably large, and the face very broad; but this is not the usual Kaftre physiognomy. Such anomalies exist amongst all nations and races, but cannot be supposed sufficient to refute the general position, that each _ race has a form of cranium and face peculiar to itself. -++ Of twenty-two ivory armlets, taken indiscriminately from the arms of Kaffres, four only were found which could admit the arm of a moderately muscular European. INHABITING PART OF SOUTHERN AFRICA. 213 ally altogether Herculean. The excess of nutrition gives rise, no doubt, to the enormously swelled legs to which many of them are liable, when, through indolence, or the infirmities of age, they are disinclined to continue the same life of activity. Circumcision and polygamy they practise with almost all African nations. According to the relations of modern and ancient travel- lers, tribes similar to the Kaffre race are found scattered over Africa, apparently unconnected with each other. We are told of a nation of Negroes, called Nubee, inhabiting the country to the west of the Nile, near the confluence of the Abyssinian and true Nile: they are described as being mild in character, and of small features, though the nose be flat, and the hair weolly: they speak a soft sonorous language, differing in these points from their neighbours. Travellers describe the Ababdes, living to the east of the Nile, as being Blacks, with European features. But as few travellers have been anatomists, their accounts cannot alto- gether be depended on. A very general belief prevails, that, by oon means, . and more particularly by pressure, the human cranium and form generally may be modified, arid permanently al- tered, and that this may at last become hereditary. It is asserted, for example, that the more remarkable craniolo- gical differences amongst nations are occasioned by external pressure; that the flatness of the African nose arises from the same cause; that Negroes are bandy-legged, because they are carried during infancy on their nurses’ back; and - that the large feet of the Kafire, and the small ones of the Bosjeman, are owing to an abundant supply of food to the former, and a deficient one to the latter *. All such asser- * BLuMENBACH de Nat. Variet. 214 ON THE ORIGIN, &. OF THE NATIVE RACES tions are constantly refuted by an appeal to facts. The feet and hands of the Kaffre and Bosjeman are strictly and beautifully proportional: though they be carried during infancy in the same manner as the Negro, they are never bandy-legged or deformed. The African nose is flat, inde- pendent of any mechanical skill exercised by the nurse; and human crania are fashioned all over the world by the hands of Nature, and not by man. Var. Moncou.

The females have remarkably pro- minent nates and elongated nymphze; both these peculiari- ties are removed by a single cross with the Kaft're or Euro- pean. ‘The Bosjeman have uncommon powers of vision ; this also is lost by intermarriage with another race. The cranium is finely formed, and thin; the nasal processes of the superior maxillary bones large and broad: these give to the Mongol and Bosjeman the appearance of breadth at the root of the nose. The foramina for the transmission of the hypoglossal nerves, are very large*. The cranium, viewed vertically, is nearly equal to the well-formed European head. The parietal bones bulge out very much, and the cranium is at this point broadest. It agrees with the Mon- gol in having the occipital foramen larger than in the other races. The floor of the orbit does not encroach so much on the cavity as in the Mongol; this affects the physio- gnomy to a considerable extent, in so far as regards the direction of the eyes. The habits of the Bosjeman race have been described by most African travellers with sufficient accuracy, and I shall therefore limit my remarks to a few points of resemblance between the true Mongol and Bosjeman races. This con- sists, first, in the countries they inhabit, which, in either case, are vast elevated sandy deserts, nearly destitute of herbage and water: secondly, in the partiality both races * These foramina are decidedly larger in the Black than in the White races, but more particularly in the Negro. They clearly indicate the passage of a proportionally large nerve, 216 ON THE ORIGIN, &c. OF THE NATIVE RACES have for horse-flesh as an article of diet, preferring it to every other sort of food ; they strictly merit the appellation of Hippophagi: lastly, in the acuteness of their vision, which almost exceeds belief. I have found their sight to be equal to that of most Europeans when aided by excel- lent hand-telescopes of the best construction. The Bosje- man is ingenious, clever, and neat-handed ; his powers of mimickry are great, his understanding good. He readily acquires languages, and his speed of foot is almost prover- bial. The origin of the race, by which I mean the mode of their descent, and separation from one or other of the more extended varieties of the human race, is:one of the most interesting inquiries which the natural history of Man pre- sents. To connect the Bosjeman with the Mongolin variety, we must step at once from the Peninsula of Southern Aim- ca, to the great central deserts of Asia; the intermediate links are lost,—the intervening races unknown. History, though not altogether to be depended on in the considera- tion of events so remote, must not in the present instance be despised. Though surcharged and disfigured with fable, there is one fact to which such constant allusion is made, as almost to put it beyond a doubt,—lI allude to the fre- quent descents of the northern Asiatic races on the south- ern states of Europe and Asia. The valuable monuments of antiquity, stall preserved in the Cave of Elephantina, in Peninsular India, attest the predominating presence of the Mongol race, at a period removed from the birth of our Saviour by more than 2000 years *, and that, at that time, * Compare the annexed drawing (Plate VII.) of the female figure sculp- tured in the Cave of Elephantina, and copied from the ‘* Recherches sur VOrigine des Arts,” with the beautiful and expressive portraits of the Bos- jeman and Hottentot races by Mr Dantetts in his “ African Scenery.” - INHABITING PART OF SOUTHERN AFRICA. 217 the Mongol physiognomy bore the strongest resemblance to the present Chinese and Bosjeman races. The early intro- duction of the Mongol or Northern Asiatic races into Pe- ninsular India is further attested by their influence on the modern Hindoo; for though the excellent BLumEnBacH assures us that the Hindvo cranium is quite equal in beauty and proportions to that of the Turk, and consequently re- fers the race to the Caucasian variety, yet, in the Hindoo heads I have examined, the development of the upper jaw has not been strictly Caucasian *. The vast antiquity of the Mongol hordes of Asia is fur- ther proved by the early establishment of the Chinese em- pire; and though I am fully persuaded of the still greater antiquity of those of Hindostan and of Egypt, yet many passages in HERoportus point out that the Mongolic tribes, with a rapidity even exceeding the Caucasian, rapidly as- sumed the form of great and warlike nations. It would seem, then, from a hasty examination of histo- ric records, of the remains of antiquity, and of the laws and religious ceremonies transmitted from generation to genera- tion, that at a very early period the Mongol races penc- trated into Europe? and southern Asia; and there is no- thing improbable in the supposition, that they may have * The inspection of a fine collection of skulls, collected on the Banks of the Ganges, and which, through the kindness of Professor Jameson, I was enabled to examine immediately on their arrival, has confirmed me in this opinion. In these skulls, which, with the exception of one Negro head, seem ’ all to be of the Caucasian race, the cranium is quite equal to any European, and its longitudinal diameter shorter than in most: but there is a develop- ment and strength in the upper maxillary bone which, I should think, will not be found to exist in any Turkish, Syriac, or Jewish head. + The peculiar Mongol face is very strongly marked in many families now inhabiting the Highlands of Scotland, and more particularly the He- brides. 218 ON THE ORIGIN, &&. OF THE NATIVE RACES modified by their presence some of the races of central Africa. Lest it might seem an omission that I have not described the Mongol race as having penetrated into the wilds of America, I shall here state, that the few Esquimaux crania examined by me, have proved to be strictly American, nor have I ever seen the slightest approach to the Mongol head in any native American race. I have only further to observe, that most of the opinions offered in this memoir are founded not on theory or conjecture, but on an anato- mical examination of the crania of numerous races of men. For the opportunity of doing so, I am in a great measure indebted to Professor JaMEson, and to Doctors Monro and Bagcuay, through whose politeness I was allowed to examine whatever specimens their valuable museums con- tained. I beg leave to offer my thanks to these gentlemen. The annexed table gives a comparative view of the mea- surements of the head in several remarkable varieties of the human race.

XII.—A Monograph of the Genus Pyrola. By Mr Davin Don, Librarian of the Linnean Society, | M. W.S. (Read 21st April 1821.) W Hen we contemplate the great increase of new spe- cies which Botany is daily acquiring, Monographs are ren- dered indispensably necessary to the exact knowledge of the species which compose particular genera, and more especially of such whose species are nearly related to each other. The genus Pyrola, although far from being nu- merous in species, has nevertheless been hitherto involved in much confusion. I have corrected the synonymes, and endeavoured to improve the specific characters of the older species; but, considering tne great difficulty which attends such a task, I fear, in the latter point, I have not in many instances been successful. For the new or rare species con- tained in the following pages, I am indebted to the kind- ness of Mr Lampert, and Mr Brown. The last distin- guished botanist, who is now in possession of the Banksian Herbarium, has with great liberality permitted me to ex- MONOGRAPH OF HE GENUS PYROLA. 221 amine the several new species contained in that splendid collection. The genus Pyrola belongs to the natural order Ericea, as now constituted, comprizing the Hvice and Rhododen- dra of Jussixu, and to the section of true Evicee, from which it would be unnatural to exclude the Vaccinee of M. Dr Canpotie. The Monotropea, another section of Eri- ce@, first proposed by Mr Nurratt, in his Genera of North American Plants, consist of Monotropa and Hypopithys (which ought tobeagain united to Monotropa, being not sufli- ciently distinct from it),and his new genus Pterospora. 'These in many respects approach near to Pyrola, both in habit and characters, and especially as there is a leafless species of Py- rola ; but the manner of emitting their pollen is totally dif- ferent, not being by pores, but by lateral fissures. The - anthers of Monotropa are not, as Mr Nutrtaut has sup- posed, unilocular, although, after shedding their pollen, and from the peculiar mode of emitting it, they appear to be so: they are flat and circular, furnished with two very short obtuse horns at their base, and emit their pollen by two transverse fissures on their internal surface. Those of Pierospora, on the contrary, shed their pollen by longi- tudinal fissures, and have two very long subulate horns at their base. ‘This plant appears to be the link between these two sections. ; The whole genus being Sane natural, I have pre- ferred retaining it entire. I have separated the whole into two divisions, and these I have again subdivided into sec- tions. The first division contains the largest portion of the - species, consisting of those the valves of whose capsules be- gin first to open at the base, with their margins connected with an intricate fine tomentum, with alternate leaves, and 999 MONOGRAPH OF THE GENUS PYROLA. flowers disposed in racemes. The second division consists of such as have the valves of their capsule beginning to open first at the top, and their margins unconnected by any kind of tomentum ; with verticillate leaves; flowers solitary; or corymbose. ‘This division contains only four species, subdivided into two sections. To the first section belongs P. uniflora ; and to the second belong P. umbellata, ma- culata, and a new species P. Menziesii. These three last constitute the genus Chimaphila of Pursu, the Chimaza of Mr Brown. I have, however, preferred considering them as a section rather than a distinct genus. They differ chiefly from the other species by their stipitate filaments, by the valves of their capsule opening first at the top, with their margins destitute of the connecting tomentum, and the lobes of the receptacle being bipartite: these two last characters they have in common with P. wnifiora. The style, which, in P. wmbellata, is immersed in the germen, is very short in maculata, so as to be just distinguished from it; but, in P. Menziesti, which is very nearly related to the last, it 1s perfectly distinct from the germen. Their general habit has been much msisted on as a just reason for their separation; but this difference in habit is not near so striking in them as in P. uniflora and aphylla, and yet the flowers of the latter are so like those of the rotundifolia, that unless for a slight difference in the lacinize of the calyx, they might readily be confounded. The species of this genus are extensively diffused through the northern Hemisphere. In the Temperate Zones they are chiefly met with in mountainous situations, some of the spe- cies, such as P. uniflora and secunda, extending to consider- able elevations: in ie Frigid Zones, on the contrary, they are only to be found in bho! lowest and narrowest plains ad- jacent to the sea, and are never met with in these regions MONOGRAPH OF THE GENUS PYROLA. 293 beyond the limit of trees. Most of the species extend across the Continents of Asia, Europe, and America. ‘There are specimens of secunda and wniflora in the Banksian Herba- rium, from the islands on the north-west coast of America: The P. picta of Smit is found on the north-west coast of America, and in mountainous situations in Japan. Some species, however, are of more limited diffusion: thus, P. asarifolia, maculata, and elliptica, have only been found in - North America. The P. dentata, Menziesii, and occidenta- lis, are still more confined, being only found in particular districts. Their favourite places of growth are woods, especially old pine and birch forests, and bushy places, and moun- tainous heaths, in a dry light soil, particularly that formed from decayed vegetables, mixed with a great proportion of siliceous earth. All the Pyrolze are possessed of a strong astringent qua- lity, and were formerly much esteemed for supposed heal- ing properties: they are now wholly disused. The P. ma- culata, however, is deserving of the attention of physicians, and is held in great esteem among the Indians of North America, who call it, according to Mr Pursn, Sip-tisewa. This botanist tells us, that he has witnessed the beneficial effects of a decoction of this plant, in a very severe case of hysterics; and I am credibly informed its decoction has proved very serviceable in scrofulous diseases. 994 MONOGRAPH OF THE GENUS PYROLA- 214.—Scop.

The acute Rivin has given very accurate figures of the different species of Pyrola, far surpassing those of his pre- decessors, and even those of most of the modern botanical writers who have noticed them. He was the first who dis- tinguished the P. media, of which he has given a very cha- racteristic figure, under the name of P. folio obtuso. The figure of P. minor, in English Botany, possesses many glaring faults; the flowers are exhibited as spread- ing, and the petals acute. ‘These mistakes are the more remarkable, as we know of no Pyrola with acute petals, and very few with spreading flowers. The P. rosea of the same work, however, is a very good representation of the present plant. : 11.

In the Lambertian Herbarium, I had ascertained this to be a species distinct from P. maculata; and on examining the genus in the Banksian Herbarium, I was glad to find it confirmed as such, by its being previously determined and named by Mr Brown. It certainly has a striking resemblance to P. maculata, and without careful examination might readily be over- looked for that species. The plant, however, is much smaller. The leaves are somewhat acute at the base, never spotted on the upper surface, and often alternate,—a cir- cumstance which I have never remarked in maculata. ‘The peduncles are much slenderer and shorter, quite smooth, never bearing more than two flowers. The laciniz of the calyx are oblong-ovate, acute, quite smooth, as well as the pedicels. ‘The bracteze are very different from those of maculata, being broad and round. The petals are oval. The appendage of the filaments is not so hairy. The tubular pores of the antherze have a straight margin, never revolute as in P. umbellata and maculata. The style is much longer, and somewhat elongated from the germen. The stigma is smaller, and hemispherical. XITI.—Descriptions, Characters, and Synonyms of the different Species of the Genus Larus, with Critical and Haplanatory Remarks. By W. Macciuuivray, A. M., ‘Member of the Medical Society of Aberdeen, and Corresponding Member of the Wernerian Society. (Head 10th January 1824.) oareE NES a nee Tuere is scarcely a genus of birds im which more confusion has reigned than in that which forms the subject of the present memoir. To those versed in the study of birds, and especially to those who have laboured to acquire a knowledge of the species which are found in our own country, no apology is necessary for an attempt to dissipate the uncertainty and doubt which every one experiences on comparing the specimens which he may have precured with the descriptions of authors. ‘T’o the student alone, it may be necessary to observe, that the species of gulls, forming a very natural genus, and being, in many cases, most close- ly allied in manners, in colour, and in size,—and, moreover, presenting much particular diversity, chiefly with respect to plumage at different ages, in the same species, together with a strong general resemblance in different species dur- ing the first years,—are very difficult to distinguish by a 248 ON THE DIFFERENT SPECIES OF mere examination and comparison of specimens, and, still more so, by attempting to refer them to the species esta- blished by naturalists. My object being to exhibit the subject in as clear a light as possible, I shall, in the first place, give a short but cir- cumstantial account of the genus considered individually, and then proceed to the particular species. But previous to this, it will be proper to observe, that the paper, such as it is, Owes its existence to Professor JamMEson, who, aware of the uncertainty that prevails in this very interesting ge- nus, wished me to attempt its elucidation. The specimens, which have furnished the principal materials of this neces- sarily imperfect memoir, form part of the splendid collec- tion of birds in the Museum of the University; the de- scriptions are in all cases taken from actual specimens, and the specific characters elaborated without any reference to those of authors. For the variations exhibited in the young birds, as well as information on other points, I have trusted unplicitly to 'TeEmmincx and Montacu: wherever infor- mation has been derived from other sources, it will be faith- a acknowledged. Larus, GuLL. Natural: Generic Character.—Beak of moderate length, straight, compressed, the sides rounded, the edges bent in- wards and sharp; the upper mandible declinato-incurvate at the end, sharpish ; under mandible forming a prominent angle near the end, at the junction of its crura, obliquely truncate and grooved internally at the tip. ° Nostrils lateral, mesial, longitudinal, linear, with the fore- end rounded, open, perforated. THE GENUS LARUS. 240 Feet rather slender, moderately long, bare above the knee: tarsi squarish, plates anteriorly, covered behind and at the knee with hexagonal scales: toes, three hefore, the middle one of moderate length, all palmate to the end, hind toe (sometimes wanting) very small, elevated ; claws slightly arcuate, shortish, bluntish, increased interiorly into an edge. Wings long, the first quill longest, the second nearly equal ; nae: longish. 3 Tail equal or slightly rounded, of twelve facies, Note.—In the larger species the beak is very deep, and the knob or protuberance of the lower mandible very dis- tinct; the beak becomes shallower and more attenuated, and the knob nearly disappears in the smaller species. With regard to the tail, there are two remarkable and op- posite exceptions; the one existing in the Larus Sabini, which has the tail furcate, like tisk of a Tern; the other- in L. roseus *, in which it is subcuneate, the middle feathers being considerably longer, the rest graduated. Physiognomy.—In their general appearance, the Gulls are intermediate between the diving aquatic birds and the Grallz, and their manners correspond with this character. The head is large, the beak moderately long, the neck shortish, the body deeper than broad, the wings long, the tail moderate, the feet somewhat slender, and bare a little above the knee. They are clothed with a very fine elastic plumage, plentifully supplied with down. The predominat- ing colours are pure white, pale greyish-blue tinged with purple, deep slate-purple, and various tints of brown. There is no difference between the sexes in point of colour : the females are somewhat smaller. * The name given pro tempore to a new species of gull, discovered by the last Arctic expedition, but which is to receive its proper designation from Dr Rrcwarpson. — 250 ON THE DIFFERENT SPECIES OF Manners.—The gulls are in general voracious, noisy and timid birds, which seek their subsistence along the shores or on the surface of the sea. They are incapable of diving, although they swim with ease; and their appearance upan the water is much more elegant than on shore, owing to their peculiar lightness, and the superior agility which they then display. They are much upon the wing; their flight is strong and buoyant ; and, when flying, they utter a loud cry, more or less deep or shrill, according to the sizeof the species, and divided by short intervals. In their state of repose, they contract the neck, and generally draw one foot up. They perform a singular action with their feet upon the sands, patting then repeatedly with considerable cele- rity, and at the same time retirmg backwards: the object of this action is not well understood, though it may be pre- sumed to be the discovery of worms or other animals con- cealed in the sand. In winter they congregate in large flocks, at the mouths of rivers, or on the sands, as well as in the breeding season, when they form a more promiscuous assemblage. Food.—T heir food consists of every thing indiscriminate- ly that they can obtain, without the exercise of courage or address, from the flesh of dead cetacea to the smallest worm. They break open the shells of crabs with their beaks, and those of cockles, by letting them fall from a sufficient height in the air. As they do not swim, their mode of catching fishes is by darting upon them as they approach the sur- face; for this purpose they pursue the shoals of herrings and sand-eels (Ammodytes Tobianus’ ; but their usual sup- ply of fish is derived from those which are casually thrown upon the beach. Young birds also fall a prey to the larger species. In stormy weather gulls sometimes leave their ordinary haunts, and proceed inland, especially in spring- THE GENUS LARUS. 251 time, to pick up the larve and worms exposed by the plough. Breeding.—Nothing is known with precision in regard to the period of incubation. Their nests are composed of dried grass, arranged in a slovenly manner, and deposited in a superficial cavity in the turf, or not unfrequently on the bare rock. ‘The number of eggs is generally three, The young are at first covered with a very fine thick down: they leave the nest very soon after exclusion, and secrete themselves in crevices, or behind stones; but they do not take to the water till they are fully fledged. The young birds are mottled with dull-grey, and brownish; the beak and feet, as well as the iris, are at first dark, and become lighter as the bird advances in age: the full and perma- nent plumage is not acquired in general till the third year. After this, at the autumnal moulting, the head and neck in many become streaked with pale brown lines, which dis- appear in spring. Country.—This genus is not confined to any particular portion of either the Old or New Continent, being found everywhere, along the shores, from the frozen regions of the North to those of the South Pole, and appearing equally in the Torrid Zone. Their partial and general migrations have not been sufficiently explained. Uses.—In the economy of Nature, one of the principal uses of these birds may be to clear the coast of animal re- mains, which would otherwise produce a noxious effect. by putrefaction ; in the same manner as the vultures, crows, and eagles, perform this office in the interior of the conti- nents and islands. ‘This may in some degree explain their general diffusion. . With regard to man, they do not seem 952, ON THE DIFFERENT SPECIES OF to be of much immediate importance. Their flesh is tough, generally lean, and disagreeable in taste and flavour: the young and the smaller species, however, are eaten occasion- ally in the outer Hebrides, and probably in other countries. Their plumage, if it could be procured in sufficient quan- tity, is much superior to that of most other aquatic birds, for the ordinary purposes to which feathers are applied. A ffinities.—However the Gulls may be placed in the sys- tems of ornithologists, their true position in the system of Nature is evidently between the Petrels or Albatrosses and Terns. There is a striking affinity, on the one hand, be- tween the Diomedca exulans, or Procellaria glaciahs, and the Larus marinus, or argenteus ; and, on the other, be- tween the Larus Sabini and minutus, and the Sterna hi- rundo and minuta. The four genera, in fact, form a very natural family, closely allied in aspect and in manners. The genus Lestris, which is by many considered as identi- cal with the present, and by others as at least most closely allied to it, I would net even place within several degrees of affinity. , It has been customary to divide the species of this genus into large and small, giving the former the name of Goe- lands, and the latter that of Mouettes, terms which have their equivalents in the English words Gulls and Mews. This division, altogether arbitrary, and having no founda- tion in nature, I would reject. Perhaps a better mode of division might be derived from the prevailing colour of the mantle or back,—or, which would be more eligible, from the form of the tail, which is even, or furcate, or cuneate. In the latter case, however, the second and third divisions would contain but a single species each. It is better to consider the whole as one undivided genus, commencing with the short and deep-billed species, such as L. bathy- THE GENUS LARUS. 953 rinchus and marinus, which are also among’ the largest,— and endmg with those in which the bill is most attenuated, such as L. minutus and roseus, which are the smallest spe- cles of the genus. : 1.

B. The above description of the adult im winter is from a specimen in the Museum. There is commonly a black bar across the white, at the end of the second quill. The markings of the first primaries vary somewhat, the oblique bar of blackish extending sometimes to the fourth, &e. In one specimen, the largest that I have seen, and apparently a very old bird, the beak was 3 inches long, 14 deep at the knob; tarsus 32, toe 32; total length 28, ex- tent 62. Nidification, &c.—Lreeds along the shores, sometimes (in the outer Hebrides at least) retirig mland to a con- siderable distance from the sea, to nestle in the islands of lakes. Nest generally made in a superficial cavity in the turf, or sometimes on the bare rock, composed of grass and sea-weeds, with occasionally a few feathers. Eggs, accord- ing to TEmMincx, three or four, of a very deep olive-green, marked with some large and small spots of dark-brown. I have never seen more than three eggs in a nest. In the Islands of Harris, the nests are commonly constructed of the cespitose roots of Statice Armeria and dried grass, and ’ are usually pretty perfect. Young Bird, fully fledged.—Beak deep black ; iris and naked circle brown; feet of a livid colour; head and fore- neck greyish-white, with numerous brown spots, largest upon the neck; feathers of the upper parts dark-brown in the middle, edged and tipped with reddish-white; trans- verse bars of this colour on the wing-coverts, lower parts dull grey, with broad zigzag lines and spots of brown; middle tail-feathers with more black than white, lateral black toward the end, all edged and tipped with whitish ; quills blackish, a little white at the tip. TEm™. | THE GENUS LARUS. 957 First Winter Plumage.—Beak bluish black ; the extreme tip, and a small portion of the base of the under mandible dusky horn-colour ; iris and naked circle brown; feet flesh- colour, tinged with pale blue, inclining to verdigris green about the knee; claws blackish-brown. Head light grey, streaked with pale brown; throat greyish-white: ocular bristles blackish ; back confusedly mottled with hair-brown, on a brownish-white basis, tinged with yellow, in patches increasing in size and deepness of tint downwards; wings mottled m the same manner, but the brown deeper, ap- proaching to liver-brown ; primaries, primary-coverts, and _ secondaries, blackish-brown. ‘The arrangement of dark colour on the back is in single spots on each feather, which also. prevails on the wing-coverts; but the quill-coverts have the immer webs brown, with processes to the number of four shooting into the light colour of the outer webs, the inter- - vals ash-grey. The bases of the back feathers are pale ash; their edges and tips of the ground colour described above. On the rump and tail-coverts, white predominates ; tail-feathers white at the base, with irregular spots and blotches ; deep-brown predominates at the end, but is irre- gularly encroached upon ; the side-feathers nearly all white. The whole under-surface whitish, tinged with ash and yel- low, with very pale brown spots; under-wing-coverts mottled, brownish-ash and pale brown; axillaries brownish-ash at. the base, with irregular bands of pale brown towards the end. The specimen from which this description is taken, is in the possession of Mr Joun Witsoy, and was killed in January 1824. Second Winter Plumage.—Beak deep-brown, tinged with blue toward the end, the tip horn-colour, the base, espe- cially of the under mandible, yellowish, tinged with brown ; angle of the mouth, and naked margins of the eyes yellow- VOL.

This description is also taken from a specimen, for which I'am indebted to Mr Jonn Wixson. At the age of two years.—After the autumnal moulting, the back and wings begin to assume their deep colour; they are’ then of a deep purplish-brown, variegated with irregular brown and grey spots; the tail is marbled with brownish ; the beak assumes the red spot, with black in the middle; the rest is a livid yellow, patched with black. TEMM. At the third autumnal moulting, the plumage is com- pleted. Trmm. Country.—Inhabits the north of Europe and America, THE GENUS LARUS. 259 extending from the Arctic Circle to the Temperate regions, Very abundant in the Hebrides, Orkney and Zetland Islands. T’emminck observes, that it is common on the coasts of Holland, France, and England, on its passage ; but Montacu remarks, that it occurs on the coast of Wales at all seasons, which it also does in the Hebrides. According to TEmMinck, it is seen, though not abundant, on the Mediterranean; and LatuHam makes it extend to the Cape of Good Hope, and even to New Holland; but whatever the Cape bird may be, the New Hela one is undoubtedly the L. bathyrinchus. Manners and Food.—It is oAataally shy, unless when enticed by food, or in the breeding season. Like the other species, it is commonly seen along the shores, and, when reposing, takes care to choose a place where it cannot rea- dily be surprised, such as a rocky eminence, the middle of an extensive beach, or the bosom of the sea, at a little dis- tance behind the breakers. It flies strongly, and, when soaring, utters a sort of loud, somewhat hoarse cackle, not unlike the sounds of a short Jaugh. Its common food is fish; but scarcely any thing comes amiss to it, and it also devours young birds. In the outer Hebrides, where it is very abundant, and where its indiscriminating voracity is proverbial, it is often seen searching the hills and heaths for carrion, which it eats in company with the eagle and raven. According to Montacu, it is a great enemy to the fishermen, and will tear and devour the largest fish from the hooks, when left dry by the ebbing tide. Distinctive Characters.—It is distinguished from the preceding species by its superiority in size, by the different form of bill, the want of the black bar on the tail, &c.

Remarks.—The specific name marinus, usually applied to this gull, is a very absurd one, all gulls being essentially marini, and this having no claim to a peculiar appropria- tion of the term. ‘The English name of Black-backed is also a very unfortunate one, as may be seen by referring to the description of the preceding and following species. 3.

Total length 23 inches, extent 46 inches. Back and wings deep brownish- purple, with a tinge of ash-grey. Four first primaries brownish-black, this colour extending, but diminished in extent, to the sixth or seventh; shafts corresponding with the colour of the webs; a white spot near the end of the first ; the rest of the primaries tinged with grey ; the whole with more or less white on the tip, sometimes obsolete on the first and second, and very narrow on the next three; secondaries, and some of the scapularies, white at the end ; the rest of the plumage pure white; a few longitudinal short streaks of very pale brown on the head and back of the neck. - Adult, Summer Plumage.—The same as in winter, only that the brown streaks have disappeared. TEmm. Note.—The greater part of the quills are often truncate, with the shaft exserted, in which case the white tip of the primaries is reduced to a mere line. Most authors, and with the rest Temminck, LatHam, and Monracu, de- scribe a spot of white near the end of the first and second quills. In the specimens which I have seen, it was only the first that had this spot. Nidification.—Nest composed of withered plants, and placed in situations similar to those chosen by the preced- ing species ; according to Tremmincx on the sands also, or on sand-banks. Eggs two or three, brownish-grey, spot- ted with black; according to Montacu, they are so like those of the L. argenteus as not to be distinguishable; that is, dark olive-brown, with dusky blotches. The young, according to Montagu, are covered with brown down, mot- tled with dusky. 962 ON THE DIFFERENT SPECIES OF Young Bird of the first year—Beak brown at the base, . and black toward the tip; feet dull ochre-yellow. Throat and fore part of the neck whitish, with longitudinal streaks of pale brown; neck and under parts whitish, almost en- tirely covered with large spots of very deep brown; upper parts and wings, with the feathers blackish-brown in the middle, margined with a narrow yellowish band; tail-fea- thers at the base pale grey marbled with black, the rest blackish-brown, excepting the tips, which are whitish; quills deep black. TEmm. 3 Other stages not known with certainty, though sie may be inferred to be analogous to those of the preceding spe- cies. Country.—This species is found in summer im all the northern parts of Europe and America; in England, and on the Baltic. In autumn, on its passage southward, is seen on the coasts of France and Holland; more common on the Mediterranean than the preceding species. TEM. Manners and Food.—The manners of this species are pretty similar to those of the last. Like it, also, it some- times proceeds to a considerable distance inland in quest of food. Montacu observes, that it is much less numerous than the preceding species. Distinctive Characters.—In the adult state this species is distinguished from the preceding, by its great inferiority of size, by the greater proportional elongation of the beak, by the bright yellow colour of the feet, those of the other being pale flesh-colour, by the different tint of the back and wings. We have as yet no good distinctive characters be- tween the young of this species and of the L. angenteus, which are nearly equal in size. Monracu professes to be ' YLHE GENUS LARUS. 263 unable to discriminate between them; and TEemmincKk passes over the subject 'in silence. The young of all the large gulls known by the older writers have been variously confounded by them, and indifferently described under various names, such as Wagel, L. neevius, &e.; all which it were better entirely to forget.

Remarks.—The term argentatus signifies properly, not silvery, but silvered ; that is, denotes, not the.colour of - silver, but a deep brown or. blackish colour, with a shade or washing of whitish or light grey upon it. In this sense itis commonly taken by the French naturalists; take, for example, le Renard argentée (Canis argentatus), the fur of which is described as ‘‘ de couleur noir, a laquelle se. mele guelque peu de blanc.” Dusmar. Looking, upon the word argentatus in this light, some have applied it as.a specific name to the present species. . Others, considering it as ex- pressive of a tint resembling that of silver, and observing that this tint does not belong to the species in question, have applied the name of argentatus to. another species, giving to the present that of fuscus. This difference of opinion with regard to the true signification of the term, has given rise to a good deal of confusion. The name of argentatus is fully as applicable to the. present, species as that of fuscus; but as Temmincx retains the latter, after Linnavs and others, it may as well remain. 264 ON THE DIFFERENT SPECIES OF. 4.

It has not been the custom with ornithologists to observe the young birds before they have left the nest. I have be- fore me a specimen (the examination of which I owe to the liberality of Dr Ricuarpson), from the last. expedition under Captain Parry, which is about a week old, and is marked “ Young of L. argentatus, 17th August 1821, Duke of York’s Bay ;” the tip of both mandibles is wine- yellow, the rest of the beak pale brown; the feet dusky, the claws yellowish. The whole body is closely invested with a dense, long, and very soft down, greyish-white on the breast and belly, of a deeper tint on the rest, mottled with brownish-grey, the spots on the head deepest. Young Bird, fully fledged.i—Head, neck, and under parts, deep grey, variegated with numerous spots of pale brown; feathers of the upper parts pale brown in the middle, edged with a narrow reddish band, tail-feathers more brown than white, of the latter colour at the base, all terminated by reddish-yellow; quills blackish-brown, a little white on the tip; beak blackish-brown, iris and circle of the eyes brown; feet of a livid brown.

At the fourth autumnal moulting, the tail is perfected, and the adult winter plumage complete. TEmm. At the fourth spring moulting, nothing remained to be perfected, in a specimen kept by Montacu, but the point of the bill, which was a little dusky; the head and neck became pure white, as it should do at that season, in the adult. Mont. Country.—Abundant in all the cold and temperate parts of Europe and America, along the shores, and occasionally appearing along the rivers and on the lakes. Manners and Food.—This species is more allied in its manners to the smaller than to the larger species, and does not, like the latter, feed upon carrion, but pursues, with the L. canus, and others, the shoals of herrings, and fre- quents the sands, where it picks up worms, asterize, cockles, and sand-eels. Distinctive Characters.—In the adult state, this species can only be confounded with the L. arcticus, to which I refer for a minute diagnostic description. The young, be- fore the blue colour of the back appears, are liable to be confounded with those of L. fuscus and L. marinus, though they may always be distinguished from the latter by their inferiority in size. TEMMINcK does not appear in- clined to enter upon this subject, and Monracu confesses his inability to distinguish them in a satisfactory manner. This therefore remains one of the desiderata in the history of the genus. THE GENUS LARUS. 267 Synonyms.—Larus argentatus, ‘Yemm. Man. d’Orn. pt. i. p. 764.— Herring Gull, Mont. Orn. Dict. I am sorry that no more synonyms can be given with certainty : authors have so confounded this, and the L. Juscus, as well as others, that it were to little purpose to exhibit a critical view of their blunders. Remarks.—The adult birds of this species vary consider- ably in size; the largest which I have seen were 25 inches in length, and the smallest 22. ‘There is also considerable variation in the markings of the outer primaries: in some specimens the black bar of the primaries extends to the sixth, there being a spot on its outer web, but it usually terminates on the fifth. A large portion of the ends of the first and second quills being white, in other specimens there is a spot of black on the outer web of the first, and a bar across the second. In a specimen from the last Arctic Expedition, the primaries are but slightly tipped with white, excepting the first, of which two inches are white, with a small brown mark at the end of the inner web, and a white spot near the end of the second quill. In another specimen, from the same Expedition, the first quill has a large spot of white near the end, beyond which a narrow bar of black, and the tip white; and there is a white spot on the inner web of ithe second near the end. The name of argentatus, or silvered, signifying a dark colour, with a superficial tinge of white, cannot with any propriety be applied to this species; that of argenteus, or silvery, I have chosen, as nearly allied to the preceding in sound, and, although not by any means peculiarly appli- cable to this species, yet as sufferable as that of marinus applied to another species, and much for the same reascn. 268 ON THE DIFFERENT SPECIES OF 5.

Man. d’Orn. pt. 11. p. 764. Remarks.—1 can only refer to the above authors with certainty for synonyms. Mr Enmonpston, in the Memoirs of the Wernerian Society, vol. iv. p. 501, seems to describe the present species under the name of Iceland Gull, and, in fact, exhibited the bird supposed above to be the young of the first year, as the young of his bird ; which, however, differs from mine, and 'Tremminck’s and SaBine’s Arctic varieties, as they consider them, of the Silvery Gull, in being much smaller in all its proportions. The specimen described above was considered by Mr ScorEssy as the true Burgomaster, and named so by him in his last publi- cation; and it is more than probable that the present spe- cies is the Burgomaster of navigators, as well as the Larus glaucus of Fazricius, Laruam, and others. For a fuller discussion of this point, I refer to the remarks upon the following species. . Distinctive Characters.—In point of size, as well as in regard to proportions, this species is nearly allied to the preceding, insomuch that it has been considered by Tem- 870 ON THE DIFFERENT SPECIES OF MINCK as merely an Arctic variety of it. It differs, how- ever, in the following particulars. The bill has little or no protuberance above, which the L. argenteus has, although in a slighter degree; in L. argenteus, the upper mandible is very little longer than the under, in L. arcticus it 1s considerably ; the nostrils are lmear m the former, in the latter much wider, and almost pyriform; the wings are longer than the tail in argenteus, of equal length in arcti- cus; in the former, the five first primaries are more or less brownish-black, as well as the shafts, the tips abruptly white; in the latter they are whitish, the bluish colour of the base decreasing gradually, so that a large portion of the tips is pure white, as well as the shafts. There is a much more striking affinity between the present and follow- ing species, than between it and the preceding: the distin- suishing characters will be pointed out in the next article. The young of this species are distinguished from those of the following, chiefly by their great inferiority im point — of size; they are distinguished from those of all the other ' great gulls by having no black on the quills or tail, by the greater lightness of the tints and markings, which agree with those of the following species. 6.

As this individual is not perfectly adult, having still some pale brown markings on the tail and lower neck, and being thus probably a bird of three years, I have rectified the description of the plumage by the examination of another specimen belonging to Mr Tuomas Torztr. Both these are from Shetland, and were shet, and presented by Mr Epmonpston. The dimensions of this latter speci- men are, beak 2¢ inches long, {ths deep; tarsus 23, toe 23 ; total length 28 inches.

Upper surface in general marked with transverse irregular zigzags of pale brown, deepening toward the tail, each feather being marked with several alternate bands of whitish tinged with ash and yellow, and of pale brown, the tip whitish-yellow. On the tail the bars are partially substituted by irregular spots. Primary quills irregularly marked with small spots. Under surface con- fusedly mottled with very pale brown, tinged with aia and _ yellowish-white. Note.—The above description is made up from a com- parison of three different specimens, two of which are in the Museum, and the third is from the last Expedition under Captain Parry. The two first are British specimens, one of them from Shetland, the other supposed to be from Orkney. _ In another specimen, also from Shetland, in the possession of Mr Tuomas Toraiz, to whom it was pre- sented by Mr Kpmonpston, the dimensions and tints were as follows: Beak 28 long, {ths deep; tarsus 27, toe 27; length 31, extent 63. In this specimen there is a greater predominance of ash-grey in the tints of the plumage, the inner webs of the quills are nearly pure pearl-grey, and the outer webs of the four first primaries are nearly free of spots. Beak wine-yellow along the edges, tinged with dusky above and below, and. brownish-black toward the end. It is not known whether the above descriptions of the young birds, be of the first or second winter plumage, al- though from analogy they might be supposed to be of the second, on account of the large proportion of light colour on the beak. Manners and food.—The only account we have of the manners of this species is that given by Mr EpMonpston THE GENUS LARUS. 973 of Shetland, in two papers in the fourth volume of the Memoirs of the Wernerian Society of Edinburgh, where he describes it under the name of Iceland Gull. Accord- ing to his account, it only makes its appearance among the Shetlaad Isles in winter, coming, as he supposes, from the Arctic regions, about the middle of autumn, and departing toward the end of spring. Its favourite resorts are the en- trances of the more exposed bays, or the ocean, a few miles off the land. It is greedy and voracious to a proverb, and seems peculiarly fond of carrion, occasionally entering the - bays in quest of it. In its usual deportment it exhibits little of the characteristic vivacity of the smaller species, (a remark which is equally applicable to the LZ. marinus) ; and does not hover about the sportsman, like them, when shot at, but, when once alarmed, commonly flies off: Mr Epmonpston as above.—Its food consists of fish, carrion of all sorts, and young birds: one specimen, Capt. Sabine says, disgorged a little auk when shot, and on dissection another was found in the stomach. Country.— According to Captam Saziner, they were found very common throughout Davis’ Straits and Baffin’s Bay, by the Expedition under Captain Ross, in 1818. According to Temminck, it inhabits the most northern countries in general, but in greater numbers toward the east; said to be very common in Russia. It appears in winter in the Shetland Islands, as above. It not being by any means certain that this is the L. elaucus of Fasricius, &c. little more can be said of its diffusion. Distinctive Characters.— In a mature state, this species can only be confounded with the preceding, from which it differs chiefly in size, as may be seen by comparing the di- mensions given in the descriptions. ‘There is a striking VOL. V. S OTA ON THE DIFFERENT SPECIES OF similarity, however, between the two, so great, indeed, that, at first sight, one might readily take them for the same species. ‘The beak is of nearly the same form, being in-both without protuberance on the upper mandible, which is considerably less curved than in any of the other large gulls. The principal points of difference are the following : The nostrils are much narrower than in L. arcticus, the whole habit more robust, the head and neck in particular proportionally larger, the bill more elongated, and the wings shorter. It is m the dimensions, however, that we are to look for the most decisive characters; the present bearing to the preceding species much the same relation in this respect that the Raven bears to the Carrion Crow. The young also can only be confounded with those of the preceding species, from which they differ chiefly in size, being much paler than those of any other large species, and without the dark quills and tail of the others. Synonyms.—Larus glaucus, Temminck, Man. d’Ornith. pt. i. p. 757. Iceland Gull, Mr Epmonpston, in Memoirs of Wernerian Society, vol. iv. JL. glaucus, Capt. SapinE, in Linn. Trans, vol. xii. pt. 1. p. 527. These are the only synonyms to which I can refer with eertainty. Temminck and Saprne have thought proper to extend the list. I would remark, in general, of their syno- nyms, that we cannot be in the slightest degree certain that the authors whom they quote, did not describe the L. arc- ticus. Fapricius’s account of his L. elaucus, for example, accords in all things with our L. arcticus ; and it is very probable that Latuam, by his Glaucous Gull, means it also, or has confounded the two; and it is plain that he had no distinct conception of it, from his remark regarding a bird with the primaries black at the end, and from his quoting Brisson, who, in his Larus cinereus, has assuredly THE GENUS LARUS. 975 described the summer plumage of L. argenteus. The Burgomaster of voyagers is probably more often the arcti- cus than the elacialis, and, in many cases, it may signify both. It is therefore a hopeless task to search for syno- nyms, and highly improper to apply the history of any Glaucous Gull of the older writers to the present species. Remarks.—The first satisfactory account that we find of this interesting species, is that given in a Memoir on the Birds of Greenland, by Captain Epwarp Sasinz, in which he enumerates the species observed by the Expedition un- der Captain Ross, in 1818. Linn. Trans. vol. xii. p. 527. He there describes it under the name of Larus glaucus, Glaucous Gull, observing that it is unquestionably the Burgomaster Gull of the Dutch. This description is suffi- Gently accurate and circumstantial to remove all doubt with regard to the species. He observes, that from specimens in his brother’s possession, he is enabled to render the his- tory of the plumage complete, and, at the same time, to add it to the British Fauna; from which we have to infer that one or more specimens in Mr Sazinr’s collection are from Shetland or Orkney. ‘This part of the volume was ‘published in 1818. The very celebrated Tzmmincx, in the second edition of his Manuel 2Ornithologie, published in 1820, gives a full account of the species, under the name of Larus glaucus, describing it with his usual accuracy and precision, but only in its summer plumage. ‘The length he says is 26 inches, while he also remarks that it is the largest of all the gulls known, yet the length of the L. marinus he states at from 26 to 27 inches. Of all the specimens which I have seen, two of which are adult, and four young, there is none so small as this. A. full account of the bird in a mature and young state, 52 876 ON THE DIFFERENT SPECIES, &c. - in winter plumage, was afterwards given in the fourth vo- lume of the Memoirs of the Wernerian Society, by Mr EpmonpstTow, a zealous ornithologist of Shetland. Mr E. has two papers on+the subject, the first read on the 24th March 1821, the other.on the 23d March 1822.. His de- scription. is fuller than Captain SBine’s, and he also de- scribes its manners as observed in Shetland, In the first memoir, he introduces it as a new species; and in the last remarks definitively, that although it might have previously been obscurely known, it was now for the first time de- -scribed as a British species; and from the circumstances detailed, it may with propriety receive the name of Larus Fslandicus, which he had proposed, as both designative of its “ Arctic haunts,” and commemorative of the “ vulgar appellation by which it is known in the Zetland Islands.” This Part was published in 1822; but Mr Epmonpston alludes to a description made in.1814, which I have not been able to see.. It is still necessary: to add a few words with regard to the names-of this and the preceding species. It being un- dersteod:.that. the Glaucous Gull of the older authors may signify either or beth, it would be necessary to restrict the — name of Glaucous to one of them, were its application in- dispensable. But this term Glaucous. bemg equally appli- cable: to three of the larger gulls, and a multitude of the smaller ones, and being, moreover,.liable to lead into error, is it not better. to adopt names free of all these faults? Of this kind, then, it 1s- presumed, are the names proposed. With regard to the outcry against change of names, I have only to observe, that names, as well as descriptions, must continue to fluctuate until they be rendered of such a na- ture as to be harmonized with common sense and sound judgment. ae “XIV.—Sketch of the Geographical Distribution of Plants.an Yorkshire. ‘By J.

Does not the Pinguicula vulgaris, Vaccinium oxycoccos, Empetrum nigrum, &c. indicate Sandstone? Where can we find a single rare plant on Alluvial soil? Beginning at the Spurn, and following the coast of York- ‘shire as far as Bridlington, and proceeding up the Humber to a little above Hull, including the whole of Holderness— the vale of ‘York, and from South Cave to Selby, as well as part of the plain of Cleveland to the Tees, the whole country is composed of Allwvial soil: here the botany pre- sents nothing peculiar, having the same plants as the Low- ands of other parts of England. We no sooner cross the “OF PLANTS IN YORKSHIRE. ‘278 -river Ouse, at Selby, than we approach an extensive Mag- nesian Limestone Formation, extending across the county, from Doncaster, Ferrybridge, Kippax, Thorparch, Knares- bro’ by Rippon, tothe county of Durham: this district is ‘nich in botany. At Kippax may be found, in about «a “square mile, Orchis morio, mascula,ustulata, militaris, py- ramidalis, maculata, conopsea; Habenaria viridis; Ophrys apifera, muscifera ; Neottia spiralis; Listera ovata; Allium -arenarium, oleraceum; Anthyllis vulneraria; Astragalus -glycyphyllos, hypoglottis; Carlina vulgaris; Cerastium ar- -vense; Chironia centaureum; Chlora perfoliata; Cistus ‘helianthemum; Colchicum autumnale; Daphne laureola; ‘Erigeron acre ; Galeopsis versicolor; Gentiana amarella; Hedysarum onobrychis : Ornithogalum umbellatum; Po- -tentilla verna; Rhamnus catharticus; Sanguisorba officina- lis; Sedum telephium; Pimpmella magna; Antirrhinum minus; Circa lutetiana; Campanula glomerata, latifolia ; Caucalis daucoides; Parnassia palustris, &c. &c. Through- -out the whole of this district, most of the above plants are to be found more or less abundant. At Thorparch, a few ware ones maybe added; such as, Anemone pulsatilla; “Silene noctiflora; Galium tricorne; Asperula cynanchica ; Narcissus biflorus; Pyrus aria; \Hpipactis nidus avis; Ac- teea spicata; Melica nutans; Chichorium intybus; Carduus -eriophorus; Atropa. belladonna; Ophrys aranifera? and apifera; Ornithogalum luteum, &c. &c. About Knares- bro’, Chara flexilis, hispida; Dipsacus pilosus; Geranium -sanguineum; Lepidium latifolium; Silene nutans; Helle- borus viridis, &c. Passing over this limestone, which may extend about 10 miles in breadth, from Selby, we approach ‘Leeds; the immediate vicinity of which is all clay. A few ‘plants, not very common, may be found towards Knostrop, near the river Aire, such as, Sisymbrium sylvestre ; Carda- ‘nime amara; Stellaria nemorum,.and Hottonia palustris. 286 ON THE GEOGRAPHICAL DISTRIBUTION Passing Leeds, to the north, the Sandstone Formation be- gins. (It contains, in the neighbourhood of Bramley, Wood- house, Chapelton, &c. many organic remains of vegetables : we have noble specimens of the Phytolithus verrucosus, parmatus, stellatus, striaticulmis, sulciculmis, cancellatus, imbricatus, and tessellatus.) The Sandstone Formation occupies an extensive district, by Otley, as far as Green- how Hall, where it meets the Compact Limestone: it then passes south, forming a range of alpme moors, by Ilkley, Keighley, and Halifax, to meet the range of the like for- mation dividing Yorkshire from Lancashire. Many of these heaths are of considerable elevation, as, Bardon Fell, 1663 feet ; Draughton Moor, 1074 feet; Foxstone’s Moor, 1513 feet; Otley Chevin, 921 feet; Cow Rock Rumbles Moor, 860 feet. ‘The rarer plants are, Botrychium luna- ria; Osmunda regalis; Polypodium phegopteris, dryopteris; Aspidium oreopteris, aculeatum, lobatum, dilatatum; As- plenium viride, trichomanes, adiantum nigrum, ruta mu- raria, Blechnum boreale, Pteris crispa, Cyathea fragilis, Hymenophyllum Tunbridgense, and 80 Musci, all near Halifax: Veronica montana, Scandix odorata, Narcissus pseudo-Narcissus, Pyrola media and minor, Prunus padus, Rubus ideus, chamzemorus; 'Trollius europaeus, Geranium pyrenaicum, Eprpactis latifolia, Crocus nudiflorus, &c. The moors, in general, are clothed with the three species of heath: the Empetrum nigrum, Vaccinium oxycoccos, and Vitis idea, are also common; the more elevated parts furnishing the Rubus chamzmorus, saxatilis, Lycopodium clavatum, selago, alpmum; and, at the highest part, Ar-. butus uva. ursi. Retracing our steps to Greenhow Hill, and proceeding north-west, we come to the mountain district of Craven, chiefly consisting of compact limestone. Here we are pre- sented with many most magnificent scenes, equally pleasing OF PLANTS IN YORKSHIRE. 281 to the lover of landscape and to the botanist. The rocks at Gordale Scar and Malham Cove, rising several hundred feet perpendicular, are probably not to be equalled in Eng- land. 'The mountains are of great elevation: Ingleborough 2368 feet, Pennigent 2281 feet, Great Whernside 2309 feet, West Simon-Seat 1593 feet, Beamsley Rock 1310 feet, Spode Hill Bank 1223 feet, Sutton Crag 1161 feet. Many of the summits of the higher parts of these moun- tains are covered with sandstone, producing ling and other plants common on that soil. The undisturbed woods, par- ticularly about Bolton Abbey, afford a rich harvest for the botanist. Here trees of great age, and immense magnitude, may be seen literally covered with a profusion of crypto- gamous plants, resembling a garden in miniature; Lichens hang in festoons from the branches, whilst the bark is hid- den from view by innumerable mosses, on which vegetate Hepatice and Filices. The plants upon or near Ingle- borough are, Rubus chamzemorus, Acteea spicata, Sedum villosum, Sesleria coerulea, Poa glauca, Festuca vivipara, Primula farinosa, Polemonium eceruleum, Ophrys cordata, Serapias longifolia, Rhodiola rosea, Convallaria polygona- tum, Saxifraga stellaris, oppositifolia; Thalictrum minus, Draba muralis, Thlaspi arvense, Cochlearia officinalis, Gera- nium sylvaticum, sanguineum, Gnaphalium dioicum, Solida virgo aurea 7, Serapias ensifolia, and rubra.

The high range of hills called the Yorkshire Wolds, beginning at the coast near Bridlington, is composed of chalk. 'This formation extends by Dritheld, forming a bow betwixt Beverley and Pocklington to the Humber. In this part the Ericze are not found. The only rare plants are a few common to limestone, viz. Festuca pumilis, bromoides, Gentiana amarella g, Chlora perfoliata, Astragalus hypo- glottis. Passing the Vale of Pickering (lately rendered notorious by the fossil bones discovered in the Kirkdale Cave), we come to the Odlite, extending from Scarborough, by Kirkby Moorside, Hemsley, to meet the Alluvium near Easingwold ; it then takes a turn to the east, and passes Malton, and we find on it the following plants: Chara his- pida, flexilis, Veronica montana, Utricularia minor, Sche- nus mariscus, albus, Scirpus pauciflorus, acicularis, sylva- ticus, Bromus pinnatus, Arundo epigejos, calamagrostis, Lolium arvense, Elymus europzeus, Galium tricorne, Pota- mogeton gramineum, Viola hirta, lutea, Gentiana pneumo- nanthe, Bupleurum rotundifolium, Caucalis daucoides, Pimpinella magna, Linum perenne, Drosera Anglica, lon- gifolia, Paris quadrifolia, Pyrola rotundifolia, Potentilla wverna, Geum rivale, Papaver hybridum, Ranunculus lin- gua, parviflorus, &c. ‘ The only district which I have not been able to examine is the Alum-shale, rising on the coast, from Whitby to the ‘Tees, including the Vale of Esk.

A poor man, in Craven, has made a considerable sum annually by the sale of this plant: he possesses a small garden surrounded. with gooseberry trees ; in the centre, he planted some years ago some plants of the Cypripedium calceolus ; they were left undisturbed for a long period, and have filled the garden, flowering freely, and flourishing under the partial shade of the gooseberry- bushes.

(Read 21st March 1824.): Tur portion of the animal which I am now about to . describe, and which appears to constitute an addition to the British Fauna, has been in my possession nearly four- teen years. I formerly alluded to it in the ‘* Contributions to the British Fauna,” inserted in the second volume of the Memoirs of this Society, p. 247, as a species nearly allied to the common sort found on all parts of the coast. In- deed, I entertained some suspicions that it might prove only a variety ; but having since examined many examples of the common species, and never perceived any approach: by gradation to the characters which it exhibits, I can now with some degree of confidence announce it as distinct..

By H. W. Vaysey, Esq. Surgeon to the Trigonometrical Survey, East Indies. (Communicated by Sir James Macaricor, President of Army Medical Board.) (Read 6th March 1824.) oo Ee Tus remarkable range of hills is called by Arrow- sMiITH, in his last map, the Bindeh, or Bindachull Hills. The same name is, however, given to a lofty range of hills on the left bank of the Godavery, as it passes through Goudwana, and also to those near Gualior. I shall there- fore distinguish them by the name of the Gawilghur Range, particularly as, after repeated inquiries, I have never been able to discover that they were so designated either by the inhabitants of those hills, or of the neighbouring plains. They take their rise at the confluence of the Poorna and Taptee rivers, and, running nearly E. and by N., terminate at short distances beyond the sources of the Taptee and. Wurda. To the southward they are bounded by the valley of Berar, and to the north by the course of the Taptee. The length of the range is about 160 English miles, and average breadth from 20 to 25 miles. : VOL V. x 290 BED CONTAINING FOSSIL SHELLS On the south side, they mse abruptly from the exten- sive plain of Berar,.the average height of which is 1000 feet above the level of the sea, and tower above it to the height of 2000 and 3000 feet. The descent to the bed of the 'Taptee is equally rapid, although the northern is less elevated than the southern side of the range. The outline of the land’ is generally flat, but much broken by ravines, and by groupes of flattened summits, and isolated conoidal frusta. ‘The summits and the flat land are for the most part remarkably destitute of trees, but they are thickly covered with long grass. In the ravines and passes of the moun- tains the forest is very thick, and in many places almost impervious. ‘The inhabitants are principally Goauds, whose language, manners and customs, differ remarkably from those of the Hindoos, At present their chief occupation is hunting, and cultivating small patches of land, which pro- duce a coarse rice and millet.. In former years the culti- vation must have been very extensive, since there are the ruins. of numerous. hill-forts and villages, which derived their chief subsistence from the surrounding lands. Many epportunities are afforded of studying the nature of this mountainous range in the numerous ravines and precipitous descents which. abound in every part. A Wernerian would not hesitate in: pronouncing them to be of the newest flcetz trap formation; a Huttonian would call them overlying rocks; and a modern geologist would pronounce that they owed their origin to submarine volcanoes. 7 I shall not give them any other name than the general one of 'Trap-rocks, but proceed to. describe them, and state, with diffidence, the inferences which I think obviously pre- sent themselves, on an attentive study of their phenomena. I. The principal part of the whole range is formed: of- compact basalt, very much resembling that of the Giant’s Causeway. It is found columnar in many places; and at IN THE GAWILGHUR HILLS. PALE I Gawilghur it appears stratified, the summits of several ra- ‘vines presenting a continued stratum of many thousand yards in length. 2. The basalt frequently and suddenly changes into a wacke of all degrees of induration, and I may say of every variety of composition usually found among trap-rocks. It changes, 3. Into a rock, which may be named indifferently No- dular Wacke or Nodular Basalt, composed of nuclei of basalt, usually of great specific gravity, surrounded by concentric layers of a loose earthy mass resembling wacke, but without cohesion, which, on a superficial view, conveys to the mind every idea of a fluid mass of earth, having in its descent from some higher spot involved in its course all the rounded masses it encountered, and subsequently be- came consolidated by drying. A very slight inspection is sufficient to detect the true cause of this appearance, which Is owing to the facility of decomposition of the outer crust, depending on difference of structure and composition. In none of the conglomerates or puddingstones do we observe any traces of this structure; and as it is common to the most crystallime greenstone, porphyritic greenstone, and those rocks usually denominated syenitic, there can be little doubt that it is owing to the development of a peculiar con- cretionary structure by decomposition. In a small ravine, near the village of Saulminda, 2000 feet above the sea, I saw basalt of a perfectly columnar structure, and vertical, closely connected with a cclumnar mass, formed of concentric lamellie, enclosing a heavy and - hard nucleus. Perhaps these last were the ends of columns lying in a horizontal position. ‘Near this ravine I had also an opportunity of observing the’ gradual and perfect passage of the columnar basalt into that which has been called Stratified, from the parallelism sine 292 BED CONTAINING FOSSIL SHELLS of its planes, the composition being identical, and, without doubt, contemporaneous. ‘i'hese changes. and passages of one rock into the other, are so frequent and various, as to _render it difficult to refer the most of them to. either of the rocks I have above mentioned as types. I shall therefore proceed to describe those which are distinctly marked, and their accompanying minerals. In external appearance, the columnar and semi-columnar basalt closely resembles that of the Giant’s Causeway, possessing the same fracture, in- ternal dark colour, and external brown erust. It is equally compact and sonorous. It, however, contains more fre- quently crystals of olivine, of basaltic hornblende, and of carbonate of lime. The fusibility of each is the same. Per- haps the basalt of the Gawilghur Range more nearly re- sembles in every’respect that of the Pouce Mountai in the Mauritius. This is, however, of very little importance, since every body who has travelled much in trap countries, knows well what great changes in composition and structure occur even in continuous masses. Among the minerals, calcedony and the different species of zeolite, are rarely found in the columnar basalt, but they are of frequent oc- currence in that which is semicolumnar. The wacke or indurated clay is as various in character and composition as the basalt, and, unfortunately, I have no type with which to compare it, as in the case of the basalt of the Giant’s Causeway: Its colour varies with its constituents, but is most usually grey. It is easily frangible, very fre- quently friable, and is almost always porous and amygda- loidal. It appears to be composed of earthy felspar and hornblende, with a considerable proportion of oxide of iron. It is always easily fusible into a black scoria or glass, ac- cording with the quantity of zeolite which it contains. Of all the trap rocks it abounds the most in simple minerals. » IN THE GAWILGHUR HILLS. 993 “They are Quartz and Amethyst-quartz. ‘Calcedony, and Caleedonic Agates, inclosing crystals of carbonate of lime. ‘Cachalong. “Common Opal and Semi-Opal. Heliotrope. Plasma, or transparent Helictrope. ‘Stilbite. _Analcime. Natrolite. Ichthyophthalmite. Felspar. Carbonate of lime and Green-earth. I have never been able to discover in it either augite or hornblende in distinct crystals. ‘When the surface of the - land is strewed with these minerals, it is a certain indication that the rock beneath is wacke. With regard to the situa- tion of this rock, I think I have rarely seen it on the sum- mits of hills, but much more frequently at their bases, and forming flat elevated plains. I shall have occasion to ad- vert to this rock again when I proceed to describe the fos- sil shells. | ‘The nodular basalt is perhaps the most common form of trap m this mountain-range, as well as in other parts of India. It more commonly forms the surface than either of the other recks, and is as frequently seen on the summits as it is at the bases of the mountains. It rarely abounds in minerals of any kind. It is the principal source of the rich black diluvial soil, commonly called «* Black cotten soil”: of India. I have little to add to the former description of it Its internal structure is sometimes beautifully developed ‘by decomposition, since, in a mass of about six inches dia- meter it is possible to count above twelve concentric layers, 294 BED CONTAINING FOSSIL SHELLS and, on striking the nucleus a slight blow with a hammer, one or two more layers are broken off. _ It is owing to this facility of decomposition that the annual rains carry down such vast quantities of alluvial soil from its surface, which is, moreover, always strewed with an abundance of nuclei, in various stages of decomposition, It 1s owing to the dif- ficulty with which the roots of trees penetrate this rock, that they are so rare on its surface, and never grow to any size. Yet this circumstance does not prevent the Andropogon contortum and nardus from growing in the most luxuriant manner, which sufficiently proves the fertility of the soil. On ascending from the Taptee (in April 1823), I observed in a nullah a group of basaltic columns, one of which was two feet in diameter, and six-sided. When near the summit of the flat table-land of Jillar, I entered a pass, formed on one side by a perpendicular section of the rock from 25 to 30 feet, and on the other by a rapid descent of 40 or 50. The lower part of the section, as well as the pathway, is com-— posed of the wacke or indurated clay of the kind before mentioned, of about 10 feet in thickness. Lying on it is a stratum of earthy clay, of different degrees of induration and purity, 20 yards in length, and about 2 feet im thick- ness, containing great numbers of entire and broken shells. This possesses all the characters of a stratum, since the hori- zontal fissures are parallel, and are prolonged, with a few interruptions, through the whole extent. ‘The accompany- ing sketch (PlateVIII. bottom) will serve to give a tolerably correct idea of the mode in which the stratum appears to overlie the lower rock, and to have been depressed by that which is supermmcumbent. ‘The upper rock consists of about 15 feet in thickness of the nodular basalt or wacke, the nuclei being of all sizes. ‘The vertical fissures which are so remarkable in trap-rocks, are prolonged from both the upper and lower rocks into the shelly stratum, although Wern: MemiVol, Vi page) PLATE VIL SS BASS Ry SSS S SY x SSS SS WS SS SS if hiff ASIN YY Nee yf Yy Witt cota willl . {) fl pil | at (!

The stratum is com- posed of a highly indurated clay, fusible before the blow- ‘pipe, into a fine black glass; and neither it, nor the shells it contains, effervesce in acids. ‘The shells are for the most part flattened, and belong either to the genus Conus or ‘Voluta. It is not possible to conceive that:so fragile a sub- _~stance as a thin land-shell should have been so completely flattened, without fracture, unless it had been previously -softened by some means, which, at the same time, produced -@ sufficient degree.of pressure to effect its flattening. I have attempted in the sketches of the shells (Plate VIII. fig. 3, 6, '7,) to give a representation of the degree of flatten- ang, but I fear that it can only be well understood by ex- samining the specimens themselves. Neither the reck nor its shells effervesce in acids. Westward, the ground is covered. by the debris of .a shelly conglomerate, much more indur- sated and impregnated with green-earth*. Some of the shells care entire, but these are rarely flattened. ‘The matrix ap- -peai's to be siliceous, and in some cases approaches to im- perfect‘heliotrope. It is not fusible before the blowpipe. I may here mention, that, in:a report to the Marquis of ‘Hastings, in June 1819, I mentioned the existence of shells an trap-rocks at Medcondah, at a height of 2000 feet above the sea. The hill was composed.of nodular trap; and lying “on its surface were numerous pieces of siliceous stone, con- ‘taining shells -of the genera Turbo and Cyclostoma. The — ‘specific gravity of the stone varied from 2 to 2.5. The ‘shells did not. effervesce in acids, although. some of them preserve their external polish. Internally, some of the _ stones appeared to pass into flint, particularly those of small ‘specific gravity, whilst their external surface effervesced in ‘© Exhibiting cavities and shells in «relief. From:the shape of the _ former, there can be no doubt of their having once contained shells - 206 BED OF FOSSIL SHELLS acids. Some of the small shells are completely changed. into calcedony. Specimens of these shells are lodged with. the Asiatic Society. | It is a remarkable fact, that the only remains of animals. hitherto discovered in India, should be found in trap-rocks, and under such peculiar circumstances. 1mo, They are found in situations where there are no indications of the former existence of lakes; 2do, Both the shells and matrix are destitute of carbonic acid; 3ti0, The former are in many instances squeezed flat, without fracture, and in some cases commixed with their matrix. These effects could only have been produced by the agency of heat, and consequently the modern theory of submarine or subaqueous volcanoes will best serve to ex- plain the phenomena. ‘These shells were deposited in the. stratum of clay in which they are now found, and when forced up by the mass of wacke beneath, they were most _ probably at the same time covered by the nodular basalt.. Thus we have heat to drive off the carbonic acid, and soften these shells, under a pressure which assisted the pro- cess, and at the same time flattened them. I have numerous collateral proofs of the intrusion of the trap-rocks, in this district, amongst the gneiss, which do not allow me to doubt of their volcanic origin. I shall take an early opportunity of completing the history of the trap- rocks of India, for which I have been collecting materials for several years past. | HYDERABAD, } July 24, 1823.

By H. W. Vaysry, Esq. Surgeon to the Trigonometrical Survey, East Indies. «Communicated by Sir James Macertcor, President: of Army Medical Board.) (Read 6th March 1824.) ie Tue Hill of Seetabuldee, although agreemg in form and interior structure with other basaltic hills in its neigh- bourhood, merits a more particular description, on account of some peculiarities in the composition of the main rock, hitherto unnoticed by geologists, and for the opportunities afforded by its extensive quarries of studying the varied structure of the rocks of the Trap family, which is rarely to be seen im so distinct a manner. The mass of the hill is composed of porous basalt, with a semi-columnar appearance, derived from numerous verti- cal fissures. It passes, at some places ina gradual, and at others in an abrupt manner, into a coarse porous wacke or indurated clay, which in its turn changes, in a similar manner, to the nodular basalt or wacke, of which the northern and southern summits of the hill are composed. OF THE HILL OF SEETABULDEE. 299 At the junction of these rocks, the passage is sometimes so gradual, as to give the intermediate rock an indeterminate character, partaking of the nature of both. At others, it is abrupt; yet, notwithstanding the abruptness of the change, the vertical and horizontal fissures are prolonged into each other, and cross the line of junction. I shall not here enter into a more minute detail of these appearances, but shall content myself with observing, that the most satisfactory explanation of these phenomena is derived from that theory which ascribes to the trap-rocks an igneous origin, under pressure of a great body of water. The semi-columnar basalt, forming the greater part of the hill, is very porous, containing numerous amygdaloidal cavities, which are for the most part merely lined with a peculiar mineral, which I presume to name Conchoidal Augite. Sometimes, however, they are nearly filled with it, or with calcedony, semi-opal, or carbonate of lime; the calcedony being usually covered with a coating of green earth. The rock itself is composed of hornblende and fel- spar, with the augite so profusely disseminated, that it ought to be considered, in some cases, as a constituent of the reck. The rock 1s fusible, and is of considerable spe- cific gravity, notwithstanding its porosity. The vertical and horizontal fissures are not always straight, but are at. times waved; they are also sometimes lined wiih an infil- tration of calcedony coated with clay and chlorite. This rock is succeeded by an indurated clay or wacke, which, at its junction with the basalt, frequently partakes of its semi-columnar structure, the vertical fissures being _prolonged into the wacke, and the schistose structure of the latter extending into the basalt. These changes may be very favourably seen in the fosse which surrounds the for- tification. 300 ON THE GEOLOGICAL STRUCTURE The indurated clay or wacke seems to form but a small proportion of the hill, as it‘1s not seen in the hollow be- tween the greater and lesser elevation, the semi-columnar basalt being there uncovered by any rock. It also contains crystallised carbonate of lime and semi-opal, but calcedony coated with green earth is the most common mmeral found an it. ; | This rock passes into the nodular wacke, which, on a casual inspection, appears to be a collection of stones rounded by attrition, and involved in a matrix of clay; when examined more carefully, it is evident that this ap- pearance is owing to a peculiar modification of the concre- tionary structure, developed by decomposition. Nuclei, of various sizes, are enveloped by concentric lamella, which peel off, as decomposition destreys their cohesion. They are consequently seen in various states of decay, and of sizes varying from several feet in diameter to several inches. But their true nature is easily discovered by the mutual mdentation of the different lamellze which surround their respective nuclei, the centres from which this pseudo-crys- tallisation has proceeded. The existence of the vertical and waved fissures need scarcely be adduced as farther proof that they are not the product of alluvial detritus. It appears most probable that they owe their forms to molecular magnetic attraction, since they conta a very large proportion of oxide of iron (nearly 25 per cent.), as may be perceived by the great specific gravity of hand specimens. ‘The nodular wacke or basalt is one of the most common forms of trap in the extensive districts composed of the rocks of this family south of the Nerbuddah. It occurs perpetually in the extensive and lofty range of mountains situate between the Poorna and Taptee rivers, and appears to form their principal mass. It is found OF THE HILL OF SEETABULDEE. 304 equally abundant: throughout the whole of Berar, part of the provinces of Hyderabad, Beeder, and Sholapoor, and appears to form the basis of the great western range of trap-hills which separate the Konkan from the interior of the Deckan. It is probably one of the main sources, when decomposed,, of the black diluvial soil, to which Hindostan owes so much of its fertility. The valley or extended plain of Berar, that of Hoshungabad, of Seronge, of Irundiala south of the Kistnah, of the Palnad bordering the Kistnah, and numerous others, all lie near the course of rivers, which at some former period have covered these plains, and formed their extensive ceposites of alluvium. Wheiher the deposi- tion originated in some sudden and partial inundation, or whether it was owing to the gradual subsidence of the -wa-. ters of the great deluge, I think may be determined by cautious investigation. Iam at present inclined to think that the most probable cause was the latter. The hill of Seetabuldee offers favourable opportunities, if the quarries are extended, of ascertaining positively, whether the basalt is merely a superficial deposite, or is deeply connected with a mass beneath. It is surrounded on all sides by gneiss or slaty granite, which is found at the base of the hill a few feet deep. Perhaps Nagpoor af- fords more opportunities than any other part of India, of studying the geological history of these rocks, as it is situate near the junction of the primary and overlying rocks. Numerous opportunities must arise during the excavation of wells and baths, of ascertaining the connection of the strata beneath. A well, in Mr A. Gorpon’s garden, near the base of the hill, of about 40 feet depth, penetrates through three or four feet of black soil, succeeded by a magnesian siliceous clay, which appears to owe its origin $02 HILL OF SEETABULDEE. to decomposition of the gneiss, by which it is immediately followed, and which continues to the bottom of the well. From the summit of the hill of Seetabuldee, the differ- ence in the outlme of the rocks eastward is very perceptible. The flattened summits, and long flat outline, with the numerous gaps of the trap-hills, are exchanged for the ridgy, peaked, sharp, outline of the primary rocks*. At Ramteak and its vicinity, the rocks are of granite and gneiss. At Doonguree, at Pullorah and Parsoonee, are found crystallised marbles passing into gneiss, capable of receiving a fine polish. ‘* Foliated black manganese ore,” in large quantity, 1s found here (Jameson’s Mineralogy, third edition): some of the marbles contain a small quan- tity of magnesia. At Khoraree, a dolomite, or magnesian marble, is found, also in gneiss. At Nyakoond Pasonee, bed of the Pesh, granite and gneiss of various kinds, quartz- rock, and sandstone, occur. . P.S. J have lately had an opportunity of fusing a large piece of the Seetabuldee basalt in a steel-furnace. The pro- duct, after an hour’s fusion, was a fine black opake stone, resembling porous obsidian. Glass-bottles are commonly made in the Mediterranean from basalt, and that of Seeta- buldee seems to be of an equally favourable nature for that purpose. ® Captain Bayley’s plates of the battle of Seetabuldee give a very cor- rect idea of the first outline of the basaltic trap-hills at Nagpoor.

F.R.S.E. M.W.S. &c. . (ead 20th March 1824.). —— EE Tus eoralline * is irregularly branched. Each branclx arises from a cell (or denticle), which has enlarged into ar ovate vesicle, slightly wrinkled across. From the top of this vesicle a tubular stem proceeds, thinly covered on one side with a row of cells, some of which are enlarged into: vesicles supporting other branches.. The base of the vesicle | is united with the mouth of the cell; but the line of sepa- ration is distinct, in censequence of the cell (and branch: with which it 1s connected) being of a denser substance. In the younger branches, the communication between the central tube of the stem and the cavity of the vesicle is: free ; in the older portions, however, this connection’ ceases:. At the external base of the vesicle, from one to three tubu- lar radicles take their rise; and descend along the-support= ing stem, and others which are inferior to it, closely adher= ® See Plate IX. | 304 DESCRIPTION OF A NEW SPECIES ing to the surface. These ‘allies are, like the stems and branches, destitute of joimts. Each cell is short, scarcely the diameter of the stem which supports it, with a hori- zontal or slightly oblique mouth, and destitute of lateral or inferior processes. In all the cells I observed portions of a thin membrane connected or continuous with the mar- gin, and more’or less cup-shaped, which appeared to be the remains of vesicles, similar to those which give rise to the branches. Their nature was likewise poinied out by the remains of the tubular radicles still in connection with some of the largest portions. ‘To some of the cells cylindrical bodies were attached, which, after maceration, appeared of the consistence of the body of the polypi of several Sertu- lariee ; but, instead of terminating in a tentacular head, be- came contracted, and gave rise to branches, bearing cells. In some cases, two contiguous cells supported each a vesicle bearing a branch. The preceding description will ase to shew, that this. coralline differs from all those described by Exuis, among his Vesiculated Corallines; by Lamarck, in his genus Plu- mularia; or by Lamovrovux, in his genus Aglaophenia. But the mutilated condition of the specimen leaves much to be desired in the characters of the species. I have ob- served in other vesiculated corallmes* a capability, when placed in circumstances unfavourable for ordinary growth, of converting the polypi in the cells, into branches bearing cells. ‘The anomalous appearances of this species seem to indicate that it had recently been placed in a condition where the exertion of similar energies was requisite in con- verting both polypi and ovaria into branches, thereby ex- hibiung a curious example of viviparous reproduction or extension. " See Edin, Phil. Jour. vol. ii. p, 86. OF PLUMULARIA BULLATA. 305 The marine plants which were collected during the last Arctic Expedition under Captain Parry, were consigned to the care of Dr Hooxerr, for examination. There were a few zoophytes among them, which that distinguished botanist requested me to name. ‘Though they were all found on the surface of the sea, about the middle of Hud- son’s Strait, 29th July 1821, they were, with few excep- tions, such as Extis has described, as inhabitants of our own shores, differing, however, somewhat in habit. Among the Sertulariadae, one occurred which, from the preceding description, seems to be new, and the structure of which serves to throw considerable light on the physiology of the tribe. ‘The drawing, which is now transmitted, will serve to exhibit the different stages of its growth. (Plate IX.) Judging from the structure of the whole specimen, there seems to be ground for entertaining the belief, that each . branch, in ordinary circumstances, takes its rise from an organ, which in many other species serves the purpose of an ovarium, and was termed by Ettis a Vesicle. In this manner we can conceive each colony, the individuals of which are connected together either mechanically or orga- nically, increasing to an indefinite size, and the common base acquiring proportional strength by the tubular radicles each new branch protrudes. But in what manner are new colonies formed? The specimen examined throws no light on this part of the history of the species; but analogy leads to the conclusion, that some of the vesicles may, at times, perform their function of ovoviviparous reproduction. The appearances exhibited by this coralline lead us to infer, that those “ little regular arch-like risings,” which Exuts observed on his specimen of Sertularia myriophyllum, and which is common to the species, may be vesicles supporting branches similar to our species. In the Plumularia budlata the bodies of the polypi them- VOL. V. U 306 DESCRIPTION, We. selves appear in progress towards the formation of branclies. This curious circumstance may be accounted for, by taking ito consideration the condition in which the specimen was found,—detached, and. floating along with sea-weeds. It may have been brought from a considerable distance, and, in its new station, have suffered from several external agents. Hence it appears to have acted im a manner simi- lar to what we have witnessed in the Sertularia gelatinosa of Patias,—by absorbing the tentacula of its polypi, and enlarging their bodies into branches. These observations have been brought together, as ser- ving to illustrate the organisation of the zoophytes, a sub- ject which has been but imperfectly considered. ‘The ex- terior covering of these animals is frequently, but errone- ously, viewed as similar to the extravascular dwellings of the bee, or the subextravascular shells of the Mollusca ; while, in its mode of growth, it is analogous to bone, a cir- cumstance on which its apparent vegetating power depends.

In the second chapter are enumerated thirteen species, which seem to be of the nature which botanists call Varieties, as arising in the kinds of plants that are much cultivated. The only one that may perhaps be a distinct species, seems to be the 12th, or Terri, (p. 12.) ; concerning which, however, I know no- thing farther than what Rumphius states. Caput V. & VI. Pinanga domestica, p. 26. This is the Areca Catechu of modern botanists, concern- ing which I may refer to my Commentary on the first part u 2 308 COMMENTARY ON of the “ Hortus Malabaricus;” and I must remark, that Rumphius is as free as Rheede from the error of suppos- ing that Catechu (kath) is made from this palm; and from this error the authors of the Encyclopedie (i. 240) are also exempt. Rumphius mentions four principal varieties, and several others of less note; but none of these seem to be what botanists call distinct species. Carur VII. Pinange sylvestres, p. 39. The authors of the Encyclopedie first introduced these into the,system of modern botany, and were followed by Willdenow; but I suspect that both followed Rumphius entirely, without having seen the plants; and that Will- denow, in forming the specific characters from the stipites, has not always understood the meaning of his author. I shall now enter into particulars, the different kinds enu- merated by Rumphius being not mere varieties of cultivat- ed plants, but distinct species. Pinanga sylvestris globosa, p. 38, t. 5, f. 1, A. This the authors of the Encyclopedie (i. 241) call Areca spicata, a name adopted also by Willdenow (Sp. PI. iv, 595); but Geertner (De Semin. 1. 24, t. 9, f. 3) considers. it as of a different genus, and calls it Euterpe globosa. I doubt much of the propriety of founding new genera of Palms merely from differences in the situation of the em- bryo, and suspect that the practice will lead to an arrange- ment altogether unnatural. Few palms are more different than the Coryphas and Pinange sylvestres, that have been united to form the genus Euterpe (Ene. Meth, Sup. ii. 623). THE HERBARIUM AMBOINENSE. 309 Pinanga sylvestris glandiformis prima, p. 38, t. 6. In the Encyclopedie (i. 241), and by Willdenow (Sp. Pl. iv. 595), this is called Areca glandiformis. Pinanga sylvestris glandiformis secunda, p. 39. I think that in the Andaman Islands I have found this palm, the nuts of which were used, instead of the betel-nut, by the convicts.confined on the island. I call it Areca laxa foliolis binerviis, caudice incurvo, floribus triandris. The following account I have extracted from notes taken on the spot..

In the woods of Chatigang and Rangpur I found an- other Palm very nearly allied to this of Rumphius, and 310 ~ COMMENTARY ON which, in the former, was called Ram Gua, or Wild Betel- nut, while, in the latter, it was called Runi Supari. I sent plants to Dr Roxburgh, thinking it might be the Areca alba; but Dr Roxburgh was of a different opinion, and called it Areca triandra, a name not very appropriate, as applicable to several species.

Very nearly allied to this last is a small Palm, which I found near Goyalpara, and which is probably the Areca gracilis of the Hortus Bengalensis (68), as Dr Roxburgh received his plant from the neighbouring territory (Sylhet), and as the name is very applicable; but I did not observe the plant in the garden at Calcutta. I should have consi- dered it as the same with the next plant described by Rumphius, on account of its éruncus gracilissimus et te- THE HERBARIUM AMBOINENSE. 311 nuissimus (p. 41, § 2.); but its fruit is too large. I shall here content myself by giving a few notices concerning: this palm. Caudices aggregati, pollice vix crassiores, pedes 8 vel 9 longi. Frondes omnino ut in A. triandra. Flores non vidi.

Pl. iv. 596), call this Areca globuli- Jera; while Gertner (De Sem. i. 19, t. 7, f. 2.) calls it A. oryzeformis, which seems the preferable name, being ‘that first given. Pinanga sylvestris Saleyt dicta, p. 41. In modern systems this remains entirely unplaced. Pinanga sylvestris saxatilis, p. 42, t. 7. Willdenow calls this the Areca humilis (Sp. Pl. iv. 595.) Loureiro imagined that he had seen the plant in Cochin- china, and called it Borassus caudata, in which he is fol- lowed by the Encyclopedie (vi. 258); but then there is gr eat reason to suspect that the plant which Loureira saw _is quite different from that of Rumphius, .as the author of the Encyclopedie, copying from Loureiro, describes an undivided spadix, and three nuts in each fruit, while Rumphius represents the spadix as branched, and the fruit as resembling that of the Pinanga oryzcformis, which has 312 COMMENTARY ON only one seed. The compiler of the Supplement to the Encyclopedie (i. 140), with his usual candour and judg- ment, has abandoned this plant of Loureiro, at least as being the same with the Pinanga sylvestris saxatilis, and adopts the name Areca humilis of Willdenow. Carut VIII. Saribus, p. 42, t. 8. This is the Corypha rotundifolia of the Encyciopedie Gu. 131), and of Willdenow (Sp. Pl. 1. 201); but its be- longing to the genus Corypha is extremely doubtful, and rests entirely on the comparison which Rumphius draws between it and the Codda Pana of the Hortus Malabricus, —* que quoad folia magnam cum Saribo nostra habet convenientiam—verum tantum differt, ut diversa sit ha- benda species,” (44). The Saribus is therefore as likely to be a Chamerops or Rhapis, and still more likely to be a Licualia than a Corypha. I cannot, indeed, help wonder- ing, that Geertner (De Sem. i. 18) should have confounded it as a species with the Codda pana of the Hortus Mala- baricus. 'This renders what he says concerning the fruit of the Corypha quite uncertain, as no one can tell whether he described the fruit of the Codda pana, or that of the Sari- bus; yet I suspect that most of the recent generic charac- ters given of the Corypha are derived from this uncertain source. . Limalia arbor, p. 44, t. 9. The authors of the Encyclcpedie (u. 201) called this at first the Corypha licwala, and it has perhaps as good a claim to remain in that genus as the Saribus; but Thun- berg has made it a distinct genus; and it is now the Li- cualia spinosa of Willdenow (Sp. Pl. i. 201), a name THE HERBARIUM AMBOINENSE. 313 adopted in the Supplement of the Encyclopedie (iui. 450), and by most recent botanists. When in Chatigang, I observed a species very nearly allied to this, and sent specimens, and a description, to Sir Joseph Banks; and, on the 24th April 1798, I sent seeds to Dr Roxburgh. I have since found the same plant on the hills of the Rangpur district; and Dr Roxburgh pro- cured it from his son, for the Botanical Garden of Calcutta, where it is called Licualia peltata. I annex a description taken from my Notes. Licualia peltata stipite aculeato, frondi flabelliformi, stamini- bus distinctis. Kurup et Kurkuti Bengalensium. Habitat in montibus ultra Gangem.

Pl. 45) proposes to restore the name Lon- tarus, im place of Borassus, the name given by Linneus, and since adopted by most botanists, but derived from the name of a part (spatha) common to most palms. The name domestica is well chosen, as I have never seen the palm except near villages; while flabelliformis, the specific name usually given since the time of Linneeus, is applicable to every species which can be considered nearly related to the same genus. I consider, therefore, that Geertner was perfectly justifiable in having (De Sem. i. 21) restored to this palm the name Lontarus domestica. Indeed, it may be observed, that Linnzeus very commonly changed the names given by Rumphius for the worse, and that the plan of making the generic name a substantive, agreeing with an adjective for a specific appellation, seems to have been borrowed from the venerable Dutch Governor, al- though Linnzus has generally received credit for the in- vention. No doubt, however, Linnzus followed the rule almost universally, while Rumphius only adopted it in a great proportion of instances. Caput X. Lontarus sylvestris, p. 53, t. 11. _ In the Encyclepedie (11. 181) this 1s considered as a spe- cies of Corypha, and has the barbarous specific name wtaz. THE HERBARIUM AMBOINENSE. 315 ‘Dr Roxburgh (Hort. Beng. 25) adopted the same names, and is an excellent authority for placing it in the same ge- nus with the Corypha described by Rheede, having ex- amined the fructification of both palms. Lontarus sylvestris Yhur dicta, p. 54. This is evidently a palm, with leaves shaped like a fan, and which produces a sago; but to what genus it belongs, no'one can say, from any thing that Rumphius states. Lontarus sylvestris Cabang, p. 55. This is a palm very nearly allied to the Licualia peltata, already described, but distinguishable by the smaller num- ber of sections into which its leaves are divided. It serves, however, similar purposes, and probably belongs to the Same genus. : Carut XI. | Lontarus sylvestris altera, p. 56, t. 12... . From the fruit contaming three or four nuts, and from the general appearance of the plant, I consider it probable that this palm is a species of Borassus or Lontarus. Capur XII. & XITI. Palma indica vinaria secunda, p. 57, t..13. Burman, im his Commentary, considered this is a Cha- meerops; and the authors of the Encyclopedie (vi. 258), misled by Loureiro, looked upon it as a Borassus, which obtained the specific name gomutus. Both Chameerops and Borassus having fan-shaped leaves, while those of the palm in question are pimnated, these arrangements were quite unnatural, no circumstance in this natural order pro- ducing such a change of appearance as the form of leaf. Dr Roxburgh, accordingly, (Hort. Beng. 68), with great 316 COMMENTARY ON propriety, considered this as not belonging to any Linnean genus, and, adopting one of the names used by Rumphius, called it Saguerus Rumphu; which I think preferable to the name Arenga given to it by Labillardiere (Enc. Meth. Supp. 1. 441), and probably derived from Aren of the Japanese. Arbor Tsiang, p. 63. This palm, Rumphius says, has an appearance interme- diate between the Saguerus and Saribus, one having pin- nated, and the other fan-shaped leaves. On this account, it may be perhaps considered as nearly allied to the Levis- tonia of Brown (Nov. Holl. 1. 267). Caput XIV. Seguaster major, p. 64, t. 14. This is usually quoted by botanists for the Caryota urens; but, in my Commentary on the First Part of the Hortus Malabaricus, I have expressed a doubt whether this be the same with the Schunda pana, and to that Com- mentary I must here refer. CarutT XV. Seguaster minor, p. 67, t. 15. I do not find that any modern botanist quotes this palm ; and Burman in his Commentary seems quite wrong in con- sidering it as a Caryota, as it has simply pinnated leaves. It is more probably an Areca, and seems in particular very nearly allied to the Areca humilis of Willdenow, which has been already mentioned in this Commentary. It would appear that each fruit has only one seed, otherwise, from the form of the leaves, I should have thought that it be- longed to the same genus with what Dr Roxburgh (Hort. Beng. 68) called Wrightia caryototdes; and as the two THE HERBARIUM AMBOINENSE. 317 seeds of the Wrightia adhere closely, forming as it were one body, I am still inclined to think that this may be the case. I shall therefore give here some account of the Wrightia of Dr Roxburgh, as probably belonging to the same genus with the Seguaster minor. As another plant, however, has been called Wrightia by Mr Brown (Nov. Holl. 1. 467), this palm should obtain another name. In the year 1798, I found it in Chatigang, but only in leaf, and sent specimens of these to Sir Joseph Banks. At the same time I sent roots to Dr Roxburgh, but it would ap- pear that these did not succeed; and he afterwards pro- cured plants from Mr Peirard. ‘The name of this plant, as given to the last mentioned gentleman by the Bengalese, is Chilpata; but to me they called it Harina, a name I would propose for the genus. The fugitives from Aracan, or Rakhain, then in the district of Chatigan, called it Mu-zha Ma-tan Raik. I have since found the plant on the hills near Goyalpara. Harina caryotoides.

Whether this be a mere variety, or a different species, is uncertain ; but the latter seems the most probable. Sezuaster minor forma foliorum et ramorum diversa, p. 68. Rumphius says expressly, ‘* una habenda est species cum seguastro minore ;” yet, from the account which he gives, the difference seems very great. | Caput XVI. Nypha, p. 69, t. 16. This is the Nipa,fruticans of Willdenow (iv. 597), and of the Encyclopedie (Sup. iv. 98). It is exceedingly com- mon on the muddy banks of the Gangetic estuaries, from whence it is often washed away, and floats entire into the sea, where sailors mistake it for the Coco-nut palm. Carut XVII. XVIII. Sagus seu Palma farinaria, p. 72. Rumphius first describes at great length the habit of this genus, which, after him, is now generally called Sagus, although an attempt has been made to call it Metroxylon; but this attempt has luckily proved abortive. Rumphius then proceeds to mention four kinds, which seem to be dis- tinct species, although they all produce sago; but this, or THE HERBARIUM AMBOINENSE. 319 an analogous substance, 1s produced from the stem of se- veral other palms. Sagus genuina, p. 75, t. 17 & 18. Dr Roxburgh (Hort. Beng. 68) called this Sagus iner- mis ; but it is certainly the Sagus Rumphit of Willdenow (Sp. Pl. iv. 404). As it is from this that by far the greater part of sago, and that of the best quality, is prepared, I think that the name of Rumphius is by far the most appro- priate. The author of the Supplement to the Encyclopedie (v. 13) doubts, whether this Sagus genuina be a different species from the Sagus farinifera of that work (vi. 394) ; but this doubt seems unnecessary, as the sago of the Sagus Jarinifera is the worst of all others. It is to the Sagus genuina, probably, that we should refer the Arbor Zagoe Amboinensis of Seba, which Burman (Hor. Ind. 240), and - Willdenow (Sp. Pl. iv. 844), have referred to the Cycas circinalis ; for I may venture to affirm, that sago never was procured from the stem of the Todda pana of the Hortus Malabaricus (iu. 9), although the nuts of this tree, when bruised, give a flour, that is used in Malabar as an aliment. This error, clearly pointed out by Rumphius (p. 92), seems to have arisen from Rheede’s having mistaken his 'Toddo pana, one of the most common trees in Malabar, for the Soteetsou of Japan. It must farther be observed, that Rumphius, far from describing various kinds of the Olus calappoides, that produce sago, as the younger Bur- man asserts, describes the sago to be the produce of a total- ly different plant, as here mentioned; and it is, to be la- mented that the younger Burman did not attend to the ex- cellent observation of his father on this subject, contained in this volume of Rumphius, p. 78. 320 COMMENTARY ON Sagus sylvestris, p. 75. This species has not been taken up by any author that I have seen. Sagus longissima, p. 75. This is the Sagus farinifera of Geertner (De Sem.11.186), and of the Encyclopedie (vi. 394), a name not so well cho- sen as that of Rumphius; for sago is not a farina, and, if it were, this species produces the worst sago of any enume- rated by Rumphius. On this account, it is probably not the Metroxylon sagu of Rottbol, who, according to the Hortus Kewensis (v. 281), meant the Sagus genwina. Sagtis levis, p. 76. This name Dr Roxburgh (Hort. Beng. 68) has changed to Sagus spinosa, an alteration not for the better, as all the four kinds mentioned by Rumphius are spinous. I do not find this plant taken up by any other recent author. Caput XIX. Sagus filaris, p. 84, t. 19. This would seem to belong to a different genus from thes four species of Sagus described by Rumphius in the two preceding chapters. Bisula, p. 85. A palm resembling the Lontarus sylvestris already men- tioned, and therefore nearly allied to the Corypha, Licualia, and Borassus; but nothing is said to enable us to judge to which it is most nearly allied, except that its fruit, beng compared to that of the Pinanga (Areca) or Betel-nut, probably contains only one nut, and it therefore should not be a Borassus. .THE HERBARIUM AMBOINENSE. 32) CapuT XX. Olus calappoides, p. 86, t. 20, 21. The younger Burman (FI. Ind. 240) quotes the Olus calappoides (p. 86) for the Cycas circinalis of Linneus, by which this great naturalist meant the Palma furinifera Japonica, Setitson Japonensibus of Breynius (Fl. Zeyl. 393), as producing sago, although he quotes as synony- mous the Palma prunifera Japonica of the Hortus Mala- baricus (iii. 9, t. 13-21). Now, this quotation is errone- ous; for, in the places referred to, Rheede describes the Todda panna, one of the most common productions of the coast of Malabar; and although he alleges that it also grows in Japan (p. 12), where its stem produces sago (p. 13), I have no doubt that this is an entire mistake, (see the Commentary on the Sagus genuwina, and Buchanan’s _ Mysore, ii. 469) ; for Thunberg refers the Tessio, or Sotits, of the Japanese, if that be the same with the Soteetsou, Setitsou, or Sotectsou, to the Tetsice of Rumphius, which will be afterwards mentioned. 2 But farther, the proper Olus calappoides of Rumphius, described in page 86, is not figured in the tables 22 and 23, as Burman would have it. The male plant is repre- sented in tables 20 and 21, and Rumphius gives no figure of the female; but it is from the form of the female spadix chiefly, that the species of Cycas can best be determined. In the text, however (p. 87), Rumphius describes this very clearly,—‘** Extremum petioli, e quo fructus dependent, emulatur planum pueri manum seu cristam galli;” from whence we may probably conclude, that the Olus calap- poides (p. 86, t. 20, 21) is nearly related to the Cycas re- voluta, as described by Sir J. E. Smith, in the Linnean © Transactions (vi. 312, t. 29, 30); but this, it is admitted, is the Olus calappoides sinensis (p. 92, t. 24), which Rum. VOL. V. x $22 COMMENTARY ON phius clearly distinguishes from the Olus calappoides, as he also (p. 90) does the Todda pana of Rheede. If the figure of Rumphius could be depended on, we might readily dis- tinguish these species, as it represents the stipites of the. Olus calappoides as unarmed; but in the description (p. 86), he says, ** Rami (stipites) a trunco usque ad foliorum or- tum ad margines brevibus obsiti spinibus.” On the hills which bound Bengal to the east, I have found the female of a Cycas, which may be the plant of Rumphius, and which I shall here describe.

Olus calappoides, e Celebe cujus feeminina Lagogo et masculina Patuka vocantur, p. 87; ut et illa ex Insulis Ulasseriensibus, p. 89, t. 22 et 23. The account of these plants given by Rumphius is not very distinct. He seems especially to have been uncertain whether or not the Lagogo and Patuka of Celebes were different from the Olus calappoides figured in plates 20 and 21, and in Amboina called Nuvel and Utta Nuer. Perhaps they are really the same, although, in the explana- tion (p. 91), tables 22 and 23 are referred to the Lagogo and Patuka. The explanation of the plates, however, seems to have been written by Burman with little care; and it may be suspected that these two plates represent the palms which were brought to Rumphius from the Uliasser Islands. They, no doubt, represent the 'odda panna of the Hortus Malabaricus, and are therefore justly quoted by Burman (Fl. Ind. 240), Willdenow (Sp. Pl. iv. 844), Roxburgh (Hort. Beng. 71), and the Compilers of the Eneyclopedie (ii. 23), for the Cycas circinalis; while the description given of the female spadix of the Olus calappoides (tables 20 and 21) renders it certain that the latter figures repre- sent a totally different plant, notwithstanding the assertion of Loureiro (Enc. Meth. Supp. ii. 425). The Cycas circinalis is a very common plant in Malabar, and I suppose must have been mistaken for the Sagus ra- Ses — 824 .. COMMENTARY ON phia; and a report of this circumstance must have led the Compiler of the Encyclopedie (vi. 393) to make this a na tive of India, especially of Malabar. But having travelled much through this latter country, as well as through India in general, if this name is confined to Hindusthan, I may venture to say, that neither produces any species of Sagus, and the Todda panna is the only plant of Malabar that could be mistaken for such. Willdenow seems therefore perfectly right in confining the Sagus raphia, which he calls Ruffia (Sp. Pl. iv. 403), to Madagascar, although it may probably be found in other parts of Africa. Pianta Osmunde genere Pappa dicta, p. 89. We have no figure of this plant, which is a native of Celebes; nor are we even certain of its not being actually a Fern; but it is more probably a Cycas. Arbor calappoides sinensis, p. 92, t. 24. All modern authors agree in calling this the Cycas re- voluta, the female fructificaticn of which has been most ac- curately described and delineated in the 6th volume of the Linnean ‘Transactions, by my worthy friend Sir J. E. Smith. A very great difficulty occurs in Thunberg making this the tree, the stem of which produces a most nutritious substance, so precious, that it is a capital crime to export the tree from Japan, while its fruit is an esculent drupe. The drupe probably may be used as a wretched aliment in times of scarcity, as is the case in Malabar with that of the Cycas circinalis (Buchanan’s Mysore, 11. 469) ; or in times of mourning, as, according to Rumphius (p. 90), is done in Tamboca: but this intelligent and inquisitive author denies his ever having heard that a nutritious substance like sago could be procured from the stem of the Olus ca- THE HERBARIUM AMBOINENSE. ‘325 dappoides sinensis (p. 92), and he says that it is cultivated by the Chinese and Japonese as an ornament,—* ob plu- mosam ejus formam.” Rumphius spells its Chinese name Titsjiu, which is no doubt the same with Tessio, the more learned name of the Cycas revoluta, which is called Sotits, and Sodots, by the vulgar in Japan. I am inclined to sus- pect that the resemblance, however imperfect, between these latter names and. Setitsou, Sotectsou, and Soteetsou, is the only foundation for supposing that the Cycas circi- nalis produces the most valuable kind of sago; and I am inclined to think that the Setitson is not, as Rheede sup- posed, a Cycas, but a.real Sagus. Carut XXI. Manga domestica, p. 93, t. 25. This is the Mangifera Indica of Linneus and subsequent authors, a name as improper, as if we were to call the apple- tree Malifera Europawa. ‘The species of Manga mentioned by Rumphius are varieties, in a botanical sense; and, in fact, the varieties cultivated in India are fully as numerous as those of the apple found in Europe. Manga Pau in Banda vocata, p. 96, t. 26. In neither description nor figure can I discover any es- sential difference between this and the Manga domestica. Manga sylvestris prima, p. 97. Manga sylvestris secunda, p. 97. . Table 27 is said to represent the Manga sylvestris, but No notice is given to which of the species it should be re- ferred. If we might venture to judge from the position of the leaves in the figure, this should be the Mangifera oppo- sitifolia of the Hortus Bengalensis (18), of which I trans- 326 COMMENTARY ON © mitted an account from Ava, which was given to Sir Joseph Banks under the name of Mangifera Marian, the latter word being its name in the language of Ava.

From the inflorescence, as above described, it will ap- pear, that, however nearly allied by the singular position of the leaves, the Marian must be different from the plants of Rumphius, which have the flowers disposed in panicles. The two kinds of this author seem distinct species, which may be thus distinguished from each other, and from the Marian. The name given to this latter by Dr Roxburgh is now improper, being equally applicable to two other species. 1. Mangifera Mariana foliis oppositis, floribus spicatis, pe- dunculo tetragono.

On the authority of Loureiro this has been described in the Encyclopedie (Sup. i. 583) under the name of Man- gifera fetida. The acrimony of the juice, in its bark, shews a strong affinity with the genus which I called Holigarna, a name adopted by Dr Roxburgh (Hort. Beng. 22). Caput XXIV. Durio, p. 99, t. 29. This is the Durio zibethinus of modern botanists. The species mentioned by Rumphius are merely such varieties as occur in plants much cultivated. Carut XXV. Saccus arboreus major, p. 104, t. 30. I think there can be no doubt that this is the same with the 'Tsjaca maram of the Hortus Malabaricus. I know no tree better, and every word that Rumphius says, so far as I can judge, I consider applicable to the common Jaca tree of India. Notwithstanding this, Willdenow, for his Arto- carpus integrifolia, does not quote this account, which, in my opinion, is better than that of Rheede; and the Compilers of the Kncyclopedie consider it as a distinct spe- cies, calling it Artocarpus heterophylla, while the Tsjaca Maram they call A. Jaca. It is true, that they quote this plant of Rumphius with doubt, and therefore their A. he- terophylla may be a real species: but I would observe, that, some of the leaves being entire and others lobed, is no proof whatever of a distinct species; all the species of Artocarpus that I know, the Bread-fruit excepted, having the leaves on their young plants lobed, while those on the 328 COMMENTARY ON adult plants are entire. The names integrifolia and hetero- phylta are therefore ill applied to any particular species. If, however, the Artocarpus heterophylla be really a dis- tinct species, the plant of Rumphius is wrong quoted in the Encyclopedie (111. 209), and I have no doubt is identically the same with the Tsjaca Maram of the Hortus Malabari- cus (i. 17, t. 26, 27, 28) ; nor does it form even.a variety, as Willdenow would have it (Sp. Pl. iv. 189). The dif- ferent species mentioned by Rumphius are the real varie- ties which occur in this, as well as in all other plants, that are much cultivated. Burman, in his observation on this plant, I suppose, is in an error, when he refers to the Waal mendya of Her- man as being the same. I believe there can be little doubt of the Waal mendya being the Grewia orientalis (Lin. FI. Zeyl. 324). Inthe Supplement to the Encyclopedie (v. 619) is some farther account of this tree, under the name Choopada. ‘The proposal of Geertner and Commerson to place this tree in a separate genus from the Bread-fruit-tree seems to me unnecessary, and to rest upon circumstances too minute, where the number of species 1s moderate, the plants nearly resembling each other in general appearance, and the characters distinguishing from other genera clearly marked. Capor X XVI. Saccus arboreus minor, p. 107, t. 31. The Compilers of the Encyclopedie (an. 210) consider this as a variety of the Artocarpus Jaca, in which they are followed by Willdenow (Sp. Pl. iv. 189); but there is rea- son to think that it is a very distinct species, the pubescence on the leaves, and the different forms of the amenta, being sufficient marks of distinction. I have, however, never seen any plant that I could refer to this species. THE HERBARIUM AMBOINENSE. 329 It must be observed, that Wilidenow considers the Rademachia integra of Thunberg as the same with the Tsjaca maraum of Rheede, which, as I have said, is the Saccus arboreus major of Rumphius ; while the Compilers of the Encyclopedie (iii. 210) consider it as the same with the Saccus arboreus minor, and as being the original Arto- carpus integrifolia of the younger Linnzeus. Saccus arboreus minor alterus, p. 108. Saccus arboreus minor tertius, p. 108. From the short notices given of these plants in the text, it is impossible to say whether or not they should be con- sidered as varieties, or as species. In plants, however, so little cultivated as these would seem to be, the latter opinion is the most probable. Angelyquen vel Caju Bandaa, p. 109. Burman in his observation wonders that Rumphius should have confounded his Saccus arboreus minor with the Ansielt of the Hortus Malabaricus (i. t. 32); but he seems to have read no more of Rumphius than the title of the chapter, for the latter nowhere says any such thing. Towards the end of the chapter, after having described three kinds of the Saccus arboreus minor, he proceeds to state, that, in Malabar, there is still another kind of Saccus arboreus, with a small fruit, which is there called Angely- quen; and afterwards, in an appendix, he adds, that the same kind is found in Java, where it is called Caju Bandaa, and that it is the same with the Ansieli of the Hortus Ma- labaricus. Now, this is a very distinct species, which the Compilers of the Encyclopedie (ii. 210) called Artocarpus hirsuta. Willdenow chose (Sp. Pl. iv. 189) to call this plant Artocarpus pubescens, quoting the Encyclopedie with 330 COMMENTARY ON doubt, but the Hortus Malabaricus without reserve. Why he did so, I cannot exactly say. He indeed calls the leaves ** subtus pubescentia,” while the Compilers of the Encyclo- pedie call them “ inferne aspera ;” but in this they are com- pletely justified by Rheede, who says “ folia inferne aspera et manui tangenti adheerentia.” Both authors, I suspect, have fallen into an error, copying from the drawing of Rheede, and attributing to the plant “ amenta mascula pendula.” Neither Rheede nor Rumphius mention this circumstance, and the appearance in the plate I consider as originating in the specimen, from which the drawing was taken, having been kept until the parts became somewhat flaccid. : In 1801, I found a tree in Malabar, and the adjacent territory, which I have scarcely any doubt is the Ansieli; and I took specimens and a drawing, which in 1806 I gave to Sir J. E. Smith, and the following description was taken on the spot. Artocarpus hirsuta, Enc. Meth. iii. 210. Artocarpus pubescens, Willd. Sp. Pl. iv. 189. Caju Bandaa vel Angelyquen, Herb. Amb. i. 109.

Notwithstanding this, I am, however, inclined to think, that it may be the same with the Chama of the Bengalese, which I found on the hills near Goyalpara, and which is probably the same with the Chaplasha of Chatigang, which I sent to Dr Roxburgh in. the year 1798, but of which I preserved no description.

Willdenow (Sp. Pl. iv. 188) calls this Artocarpus incisa 8, considering it as a cultivated variety of the following plant; and in the Encyclopedie both are quoted, without distinction, for the Artocarpus incisa (11. 207), while the Soccus sylvestris is considered the variety 8: but these suppositions seem to me devoid of foundation, and I agree with Rumphius in considering the three species distinct. This is distinguished by its smooth leaves; and Rumphius enumerates several different kinds, some of which are spon- taneous, but still different from the Soccus sylvestris or Soccus gvanosus. ‘These kinds are, however, I think, to be considered as varieties, arising as usual from cultivation. See Sookoon, under the head Chospatlt (Suppl. v. pee in the Encyclopedie. Carurt XXVIII. Soccus granosus, p. 112, t. 33 This, as mentioned in the Commentary on the foregoing plant, is the Artocarpus incisa. «, of Willdenow (Sp. Pl. iv. 188), from which it may readily be distinguished by having its leaves scabrous above, and woolly beneath. . Of this also Rumphius enumerates both cultivated and spon- taneous varieties,—a proof of its being a species really dis- tinct from the preceding. Caprut XXIX. Soccus sylvestris, p. 114, t. 33.

This is evidently an Artocarpus, with entire leaves, which, together with the footstalk and fruit, are covered with hairs. It may very possibly be the same with the Artocarpus Lacucha of Dr Roxburgh (Hort. Beng. 66), a tree very generally diffused over India. 'The account given by Rumphius is too imperfect to admit with certainty of the plant of Celebes being considered the same with the Lacucha; but he says nothing to contradict this opinion, as will appear from the following description of the Lacucha taken by me in Ava during the year 1795, from whence I sent specimens, now in the collection of the late Sir Joseph - Banks. The tree is called Lacucha in the Sanskrita, Baral in the Hindwi, Dephal in the Bengalese, and To Pi-neh, or Wood-Jaca, in the language of Ava. Arbor mediocris.

This fruit was noticed by very early botanical writers ; but seems very inferior in ancient India, where I have seen it, to what it would seem to be in the Indian Archipelago, as described by Rumphius. Rheede (Hort. Mal. in. 51, t. 43 & 44) gives a good account of it, as found in ancient India. Plukenet then mentions it in two places; first, (Alm. 238) under Ray’s name, “‘ Malus Indica pomo an- guloso Carambolas dicta ;” and, secondly, (Mant. 36), un- der the name of ‘‘ Carambola, Malabarorum Tamaratonga Horti Malabarici.” The elder Burman (Thes. Zeyl. 148) calls it ** Malus Indica, foltis sennze occidentalis, fructu acido, pentagono, sulcato, floribus rubris.” He also gives the synonyma of preceding authors with tolerable care; and mentions the true Indian name, Kama-ranga, derived from Karma-ranga of the Sanskrit; but his explanation of this name is totally absurd. ‘The description of Rumphius comes next in order, and is excellent. ‘The sweet and sour _ kinds mentioned by him are varieties, such as occur in all plants much cultivated. Linneeus, in publishing the Flora Zeylanica, established the genus Averrhoa, and made this one of the species (178), as is usual in that work, quoting the synonyma with admirable care. In the Species Planta- rum it obtained the specific name Carambola, and continues to be called by this appellation in all subsequent authors of note; yet this name is of very doubtful origin. It is true, that Rheede asserts it to be the name in use with the Brahmans of Malabar; but he adds also, and with the Portuguese, a coincidence that would be remarkable; but the Sanskrita name is Karma-ranga, m the vulgar dialects of the north corrupted into Kama-ranga, a name which extends from the Ganges even to Ceylon; and I suspect THE HERBARIUM AMBOINENSE. 335 that even the Tamaratonga, which Rheede says is the vul- gar name in Malabar, is a mere corruption, by errors in copiers and printers, of the same word. As for Carambola, it is, I suspect, one of those productions of careless travel- lers, which are considered as Indian words by Europeans, and as European words by the Indians. Carut XXXI. Blimbingium teres, p. 118, t. 35. The synonyma of older authors may be found in the elder Burman (Thes. Zeyl. 147), and in the Flora Zeyla- nica of Linneus (177). This great author, in his Species Plantarum, called it Averrhoa bilimbi, preferring the un- couth name of Rheede, corrupted from the Malay; while Rumphius afforded two good specific names, stellatum and teres, for the two species of Averrhoa, which he described. The names of Rheede, however, continue to be used by all recent authors of note. , Carut XXXII. Jambosa domestica, p. 121, t. 37. This is undoubtedly the Eugenia Malaccensis of all bo- tanists since the time of Linnzus; and, for what I have to say on the subject, I may refer to my Commentary on the First Part of the Hortus Malabaricus, (Lin. Trans. xiii. 481). I have here, however, to add, that this fruit, in its native country, the Eastern Archipelago, has a superior quality to what it possesses as an exotic in ancient India. I believe also, that all the kinds mentioned by Rumphius, even the Jambosa calapparia (p. 122), are merely such varieties as occur in all plants that are much cultivated. ” 336 COMMENTARY ON Jambo d’Agoa Rosada, p. 123. This, as I have mentioned in the Commentary on the Hortus Malabaricus (1. c.), seems to me the Eugenia Jam- bos, the Portuguese name being a mere translation of Gu- lab Jamba, the Hindwi name of this fine tree. Burman’s observation on the Jambosa domestica (p. 124) is full of errors, mentioned in my Commentary on the Hortus Ma- labaricus, Part i. p. 27. Carut XXXITI. Jambosa nigra, p. 125, t. 38, f. 1. This is quoted by Willdenow (Sp. Pl. 1. 959), along with the former, for the Eugenia Malaccensis; but it seems a distinct species, and, without being certain, I be- lieve that it is the Eugenia purpurea of the Hortus Ben- galensis (p. 35), introduced there by Mr Colebrooke, who, I suppose, gave it this name, which I find in no botanical writer. The plant of Rumphius is not, however, quoted in the Hortus Bengalensis. The observation of the elder Burman, at the end of this chapter, is, in my opinion, to- tally erroneous, no one of the plants quoted being the same. Carut XXXIV. Jambosa aquea, p. 126, t. 38, f. 2. In the Encyclopedie (i. 200) this is quoted with doubt for the Eugenia Javanica; but as the fruit of the latter has not been described, nothing certain concerning this question can be determined. In the Hortus Bengalensis (37), without quoting Rumphius, this elegant species has been called Eugenia aquea. It was brought, along with the preceding, by the fieet of Admiral Raynier, after the cap- ture of Amboina; and, in the year 1800, I saw both in the a THE HERBARIUM AMBOINENSE. 337: garden of the late worthy Dr Anderson, at Madras. The Bengalese name given to the Jambosa aquea is perfectly generical, and it has been called Jamb by the gardeners, just as any foreign species of Quercus might by a common labourer be called Oak. Considering the deserved high authority of this work respecting the native names of plants, I think this explanation necessary; as a Bengalese name might imply the plant being a native of that country. The kind with a white fruit, mentioned by Rumphius, seems a mere variety, the effect of cultivation. Caput XXXV. Jambosa silvestris alba Utan Puti, p. 128, t. 39. In my Commentary on the Hortus Malabaricus (P. 1. fol. 27), I have mentioned the mistake into which modern botanists have fallen, in quoting this for the Eugenia jam- bos. I have no doubt of its being a totally different species, which hitherto has not been properly applied to any plant recently described. Jambosa silvestris alba Biawas, p. 128. It is impossible to say, from any thing mentioned by Rumphius, whether this should be considered as a distinct species, or as a mere variety of the foregoing. If Burman was wrong in comparing these two plants to the Malacca . Schambu of Rheede, which is at least of the same genus, he erred much more in comparing them to the Catu Tsiambu (Hort. Mal. iv. t. 8), which does not seem to be- long to the same family. Jambosa silvestris parvifolia, p. 129. In the Actuarium or Appendix to this Work (cap. 6) we are informed that a transposition of plates has taken VOL. V. x 338 COMMENTARY ON place; and that the plate representing this Jambosa 1s given in vol. 11. tab. 40; while the 40th plate of this first volume represents the Radix Deipare spuria, described in vol. ii. p. 127. After this we can only account for the Jambosa silvestris parvifolia beng quoted for the Gme- - Jina Asiatica in Willdenow (Sp. Pl. iii. 313), by supposing, that he looked merely at the drawing, without reading the description. 'The Compilers of the Encyclopedie (11. 739) noticed the discrepancy between the description and figure prefixed, but do not seem te have consulted the Actuarium, so as to refer the figures to their proper places. IT have no doubt of the Jambosa silvestris parvifolia being an Eugenia, and cannot see any resemblance between it and the Blatti of the Hortus Malabaricus (ii. t. 40), or Sone- ratia acida, with which Burman in his observation com- pares it. Jambosa silvestris Jamboe aha Utan dicta, p. 129. When in the north-west parts of Mysore, in the cool moist woods bordering on the lower sea-coast, I observed a tree which seemed to have a great resemblance to this plant of Rumphius; only, from not having seen the fruit, I remain doubtful. I shall, however, describe what I saw, of which Sir J. E. Smith has the specimens that I brought home in 1806.

What Rumphius says of a verruca growing below the leaves, and spreading out into a substance resembling the Cupressus marinus, seems either to relate to some Viscum or Psilotum, or to some disease similar to that which we observe in Europe on the Betula alba. Carut XXXVI. Jambosa ceramica, p. 130, t. 41. Linneus, in the Flora Zeylanica (182-186), described as species of Myrtus five plants, which he acknowledges searcely belong to that genus, and which should rather be considered as forming one, that should be called Myvcia, and of which he gives the natural characters at full length. More modern botanists have availed themselves of this hint, and Swartz adopted this genus, but chose to give it the hard Greek name Calyptranthes. One of these five plants, which Linneus at.first (FI. Zeyl. 185) called Myrtus foliis lanceolato-ovatis, he afterwards, in the Species Plantarum, called Myrtus cumini. ‘The synonyma, which Linneus quoted for this, were, the Arbor Zeylanica cuminum redo- lens of the elder Burman (Thes. Zeyl. 27), and the Anka- enda of Herman (Mus. Zeyl. 23). We are indebted to the late Dr Dryander (Linn. Trans. 11. 232) for having here pointed out an error in Herman; and that in his Herba- rium the tickets of the Madan and Ankaenda must have been changed. ‘The synonyma, therefore, of Linnzeus are totally wrong, as he described the plants of Ceylon from the collection of Herman. The Arbor Zeylanica Cuminum redolens and the Ankaenda belong therefore to the Jambo- lifera of Linnzeus (Fl. Zeyl. 139); while the Prunus Jn- y2 340 COMMENTARY ON dica fructu nigro (Burm. Thes. Zeyl. 197), the Jambulo- nes (C. B. P. 466), the Jambolous (Acost. Aromat. 209), and the Madan (Herm. Mus. Zeyl. 8), are really the plant (Fl. Zeyl. 185) which Linneeus afterwards called Myrtus Cumini. As the generic name Jambolifera, and the specific name Cumini, are thus totally founded in error, Gzertner has done perfectly nght in changing the former to Cymi- nosina (De Sem. 1. 280, t. 58, f. 6); and Willdenow should have transferred ail the synonyma, given by mistake in the Flora Zeylanica, to the Calyptranthes Jambolana, which, without any doubt, is the same plant with the Myrtus Cx- mini. An unfortunate error, however, in the younger Burman, has led Willdenow into still greater mistakes. The former quoted, as synonymous with the Myrtus Cw- mini, the Jambosa ceramica, of which I am now treating ; and the latter, joining this with some of the synonyma which Linnzeus by mistake had given to the Jambolifera or Cyminosma, made it inte a species, which he called Calyptranthes caryophyllifolia, a name which he borrowed from a mistake in the Encyclopedie. In this valuable work (ui. 198), the Perin Niara of the Hortus Malabaricus (v. 57, t. 29) is considered as different from the Jambolana described by Rumphius in the next chapter, because the painter of the latter, in attempting awkwardly to represent the leaves in proper perspective with their points bending a little backward, “ folia rotundo terminantia cum brevi apice, quee deorsum inflectitur,” has represented them as deeply emarginated ; but, on a careful examination of the descriptions of both authors, with a tree most perfectly known to me, I have not the smallest doubt that the Perin Niara and Jambolana are quite the same, and that Will- denow is wrong in referring the Jambosa ceramica to this species. In the Encyclopedie, it is considered, with some doubt, as belonging to the Eugenia cymosa of that work THE HERBARIUM AMBOINENSE. 341 (ui. 199). This doubt arises from its having been quoted as the Myrtus Cumini of Linneus; but the deep division of the calyx, very evident in the figure of Rumphius, and his having described the real Myrtus Cuminz under the name Jambolana, removes all doubt from my mind. I think that, in the woods of Chatigang and Goyalpara, I have seen the tree; but as I have not seen the fruit, I am uncertain, in a genus the species of which are so difficult to determine. In 1798 I sent specimens to Sir Joseph Banks, under the name of Eugenia calyptrata, and I now shall mention what I quoted on the spot. Eugenia cymosa, Enc. Meth. ii. 199. _ Jambosa ceramica, Herb.

Most of what I had to say concerning this plant has been anticipated in the Commentary on the Jambosa ceramica. It now remains to give what I consider the true synonyma, and a description; and I must do justice to Burman in 342 COMMENTARY ON © stating, that the synonyma which he gives to this plant seem correct.

It was called Janggali (sylvestris) Jamun (Myrcia) by the natives, and I consider it as the spontane- ous kind of this species, while the large fruit I consider as the effect of cultivation. It must be observed, that the name Janggali Jamun is given also to another species, which I call Calyptranthes ¢enuis, although I think Myr- cia tenuis would be a more Linnean and proper denomina- tion. Carut XXXVITI. Mangostana, p. 132, t. 43. This is the Garcinia Mangostana of all modern botanists. Mangostana celebica, p. 134, t. 44. Linnzeus, in the first edition of the Species Plantarum, called this Garcinia celebica, and was imitated by Burman (FI. Ind. 109), Willdenow (Sp. Pl. 11. 848), and the Com- pilers of the Encyclopedie Gu. 700). Loureiro having observed that the flower of the Folium acidum majus of Rumphius (iii. 58) differed somewhat from that of the Mangostana, established it for a new genus, which he called Oxycarpus. It was afterwards discovered by M. du Petit-Thouars, that the Garcinia celebica belonged to the same genus; but he chose to give this a new name, Brin- donia, from Brindones, the appellation by which Garcias, _ John Bauhin, and other old botanists, knew its fruit. This — innovation the Compiler of the Supplement to the Ency- clopedie (iv. 258) properly rejects, and calls the plant Oxycarpus celebica; but he rejects all the synonyma of these ancient authors, transferring them to the Oxycarpus indica. This he has done with great propriety, because the Mangostana celebica has a white juice, while that of the 344 COMMENTARY ON Mundo and Brindoma is yellow, changing into an imper- fect gamboge. | In the woods, south from the Ganges in Magadha, I have found a tree, which, as its fruit has only four seeds, I should have taken to be the Brindone; but the juice of the tree is limpid, or white, like that of the Mangostana or Oxycarpus celebica ; and the figure and account given by Rumphius of this agree so well with the Gangetic plant, that I should have considered them as the same, did it not appear clear that the Mangostana celebica is dicecious, ha- ving male-trees that preduce no fruit. This, so far as I know, is not the case with the Gangetic plant, which pro- duces both male and hermaphrodite flowers on the same stem. It may, however, have trees producing male flowers alone, although such escaped my notice in travelling ; for I found the tree in no other place. I shall here, however, describe it as the Oxycarpus gangetica, leaving it to be determined by farther observation, whether or not it be really distinct from the Oxycarpus celebica.

Rumphius, in the text, considers the Mundo as the same with, or at least very nearly allied to, the Panitsjica of the Hortus Malabaricus (ii. 45), which Burman in his obser- vation on the Mangostana (p. 134 ad initiwm) considers very nearly allied to that tree, and the same with the Man- 346 COMMENTARY ON gostana celebica. Burman is certainly wrong, for there can be no doubt, I think, that the Panitsjica is a Diospyros, which Gertner, mistaking the position of the calyx, called Embryopteris. Further, what Rumphius states concerning the juice of the Mundo, which he says is yellow, is by no means reconcilable with the Panitsjica, the juice in the un- ripe fruit of which is, as Rheede expresses it, “ humor giu- tinosus aqueo pellucidus.” I am, however, inclined to think, that the Mundo, although quite different from the Fanits- jica, is really of the same genus with the Mangostana cele- bica ; for I know a tree, which I take to be the Mundo, and which Dr Roxburgh for some time took to be the Garcinia celebica, but which, on farther consideration, he called Garcinia pictoria. I found it ma garden at Barui- pur, where it probably had been imported from abroad, and sent it to Dr Roxburgh in 1799. I also sent a de- scription and drawing to Sir J. KE. Smith, coloured with its own gum, that is, the flowers were coloured entirely with | this substance, while indigo was added for the green parts. This pigment is, however, very different from true gam- boge, being less readily soluble in water, and its colour re- maining unchanged when mixed with potass. I am inclined, however, on account of this yellow juice, to think, that this is the Kanna Gorakha of the Cingalese, or the Carcapuli of Linscot, which Caspar Bauhin, and after him Burman (Thes. Zeyl. 27), Linneus (FI. Zey!. 195), and the Com- piler of the Encyclopedie (ai. 701), confounded with the Carcapuli of Acosta, or Gorakha of the Cingalese, as Her- mans, in a letter to Syen (Hort. Mal. 1. 42), clearly points out. Although Burman says (Thes. Zeyl. 28) that the fruit of his plant has only four seeds, and although this number of seeds is found in what I have called Oxycarpus gangetica, and a greater number in that which J am now describing, yet the juice of the Oxycarpus gangetica is not THE HERBARIUM AMBOINENSE. 347 a yellow pigment ; and the number of seeds, owing to abor- tion, is very variable, a circumstance little attended to by many of the older botanists. I have, at any rate, very little doubt that the Garcinia tinctoria of Dr Roxburgh is the Oxycarpus indica of the Encyclopedie (Sup. iv. 257), al- though the Compiler says that the hermaphrodite-flowers are solitary. ‘This, indeed, is sometimes the case in the plant which I saw; although, in more perfect specimens, three, or even five, flowers at the end of the branch are more common. The flowers are also said by the Compiler to be small; but this is by no means the case with the tree seen by me, and which I shall therefore describe, as being the Mundo.

Rumphius considered this as the same with the Anona Maram of the Hortus Malabaricus (iu. 23, t. 30, 31); and the elder Burman, in his observation on this chapter, al- though he admits that the figures are somewhat different, persists in the same opinion, adding, as synonymous, the Anona maxima, ‘ foliis oblongis angustis, fructu maximo, luteo, conoide, cortice glabro, in areolis distincto ” of Sloane, which is the Anona Oviedi of Clusius, Parkinson, and J. Bauhin, and which is also quoted by Catesby and Ray for a plant described by them. Burman also added as syno- nymous the Anona indica angustifolia, “ fructu cceruleo, cortice squamato glabro” of Plukenet (Alm. 32; Phyt. t. 134, f. 4). Now, I see no very great objection to the first set of synonyma, although Rumphius alleges, that the ‘plant of Oviedo differs much from his; but the plant of Plukenet, having a blue scaly fruit, cannot be that of Rumphius, having a yellowish or reddish fruit, like a pome- granate in colour. The plant of Plunkenet may, however, be the same with that of the Hortus Malabaricus, of which ‘“‘ fructus non, uti Atamaram, e compactile lignosarum squamarum strue compositi, sed undique glabro, hyacin- thino ac tenui nitente cortice obducti sunt.” If by this Rheede means that the fruit is purple, like a hyacinth, such a plant is totally unknown to me. In other respects, his account of the fruit agrees very well with that of a plant very common in India, and which I take to be the Anona of Rumphius, although I must confess that its fruit does not exactly resemble either that delineated in the Herbarium Amboinense, or Hortus Malabaricus; nor do° the figures of the fruit, in these two works, resemble each other. THE HERBARIUM AMBOINENSE. 349 It must also be observed, that Rumphius himself doubted of his plant being the same with the Anona of Oviedo, which Plukenet says (Alm. 32) is the Cachima of the Caribbaean Islands, that is, the Anona muricata. When the elder Burman published his Thesaurus Zey- lanicus, he considered it likely (21) that the plant of Rum- phius is the same with the Anona sylvestris of Herman, or Ahughas of the Ceylonese (misprinted Alughas in Burman, a way of spelling carefully since copied), an indigenous plant, now called Anona asiatica (Willd. Sp. PI. 1. 1267) ; but since Linnzeus first introduced the species (FI. Zey]l. 225), several synonyma have been added, and especially the Guanabanus fructu purpureo, an American plant, very possibly the same with the Anona of the Hortus Malaba- ricus. I must admit, that the plant, which I consider as the one meant by Rumphius, is chiefly found about vil- _lages, and may therefore perhaps be an exotic, while the _name Nona, by which it is usually called in the Gangetic provinces, savours much of being derived from Anona, a Mexican word, as Rumphius alleges: yet the plant, accord- ing to him, differs so much from the descriptions of the American Anona, that I am inclined to think it indigenous, aad that it may be the Anona asiatica, as constituted by Linnezus (FI. Zeyl. 225). This I judge to be the case, the more especially, because it is much more generally dif- fused than the Anona squamosa, no doubt an American plant; while its fruit is execrable, and totally unworthy of transportation, and that of the Anona squamosa is deli- cious. _. However this may be, Linnzeus, in the Species Planta- rum, under the name Annona reticulata, joined the plant of Rumphius with the West Indian plant already men- tioned; and if they be different, which I think probable, I cannot say which he really meant. He took no notice of 350 COMMENTARY ON the Anona of the Hortus Malabaricus, deterred probably by the figure of the fruit, which is not reticulata, but im- bricata. In the Encyclopedie, the plant of Catesby alone was joined with that of Rumphius, and annexed to the Anona reticulata of Jacquin, to form the Anona reticulata a, while the plant of Sloane, notwithstanding the difference in the colour of the fruit, was joined with the Anona of the Hortus Malabaricus, to form the Anona reticulata 6; and an observaticn is made, that the latter seems nearly allied to the Anona asiatice. So far the author is certainly nght, that the Anona of Rumphius has an undoubted claim to be preferred to the name reticulata, having been mentioned as such by Linneeus. Soon afterwards Willdenow divided, in a similar manner, the Anona reticulata into two varieties; but, according to him, the first is the plant of Jacquin, united with that of Sloane, Catesby, and Ray, with that of the Hortus Mala- baricus, and with a new synonymon from Plumier, Guana- banus fructu aureo et molliter aculeato, which, even from this short character, seems different from either the plant of Rheede or that of Rumphius. The second variety joms the Anona of Rumphius with the Anona mucosa of Jac- quin (considered in the Encyclopedie as the Anona glabra), and excludes all other synonyma. . In the Hortus Kewensis (ii. 334), the Anona of the Hortus Malabaricus alone is quoted for the Anona reticu- lata, and no notice is taken of the Anona of Rumphius. Amidst such confusion I do not wonder at neither being quoted in the Hortus Bengalensis; but the plant which is there (p. 23) called Anona reticulata, is that which I have considered as the Anona of Rumphius, although I must admit, that our plant agrees much better with the descrip- tion of Rumphius than with his figure; for I have never THE HERBARIUM AMBOINENSE. 351 seen its fruit reticulated in any manner like what this re- presents. I may venture to say, that there are only two species of Anona in any manner common in the gardens of India. The one is the plant which will be next mentioned, about which there is no difficulty. The other is the Nona of the Gangetic provinces, called Anona reticulata by Dr Rox- burgh, which entirely agrees with the description of Rum- phius; and, notwithstanding the figure of the fruit in this author has no resemblance to that of our plant, I think he meant no other; and I strongly suspect, notwithstanding the differences both in the figure and description given in the Hortus Malabaricus, that the same plant is there meant, and that Rumphius was right in considermg his Anona and that of Rheede as the same. I am also inclined to think that this is indigenous, and that we have no American Anona common in India, except the sgwamosa.. I am not, however, by any means clear that Burman was night in considering the Indian Anona as the same with the Anona asiatica of Linnzeus. I never heard of its root being used as a dye; and, on this account, I have some suspicion that the Ahughas (Lin. Fl. Zeyl. 225), or Anona asiatica, is a Morinda. In the forests, however, bounding Bengal on the east, there has been found another indigenous species of Anona, named Suriffa by Dr Roxburgh (Hort. Beng. 43), which may be the Anona asiatica, although I suppose it to be rather the Khi of Rumphius, to be immediately mentioned. : Anona mas, p. 137. Perhaps our Anona? 352 COMMENTARY ON | Fructus chinensis Khi dicta, p. 137. This is perhaps the Anona fructu rubicundissimo of Linnezus (FI. Zey]. 509) and Burman (Thes. Zeyl. 21), excluding all the synonyma of American plants. It may, . however, more likely be the Anona sariffa of Dr Roxburgh, the plants of Southern China having a great affinity with those from the north-east of Bengal. Carut XL. Anona tuberosa, p. 138, t. 46. There can be no doubt that this and the Ata Maram of the Hortus Malabaricus (i. 21, t. 29) are the same, and that they are the Anona squamosa of Linnzeus, and subse- quent authors. Notwithstanding what Plukenet says (Alm. 32), this is what the English abroad call Custard-apple ; nor either in the East or West Indies did I ever hear it called Sweet Sop, as the Hortus Kewensis alleges (i. 334) on the authority of Plukenet (Alm. 32). It is indeed 1m- possible that any person could compare the fruit of our other species of Anona to a custard, or any thing tolerable. The Sweet Sop, m Jamaica at least, I believe to be the Anona muricata, called Cachiman in the French Islands. Carur XLI. Cujavus domestica, p. 140, t. 47. Caput XLII. Cujavus agrestis, p. 142, t. 48. Since the time of Linnezeus, the former of these has been called Psidium pyriferwm, and the latter P. pomiferum ; and Willdenow has placed no less than four species be- tween them: but there is no real difference of species, in ————. —-—— THE HERBARIUM AMBOINENSE. 353 the sense usually adopted by botanists, the two plants dif- fering much less than many kinds of Apple (Pyrus malus). Dr Roxburgh (Hort. Beng. 37) did not distinguish them by the form, but by the colour of the fruit, calling those Psidium pyriferum which have a white fruit, and those P. pomiferum which have a red fruit. This, however, does not appear to have been the distinction of Rumphius, who considered the kinds that are acid, and approach the crab or unimproved plant, as the Cujavus agrestis; and the kind with a sweet fruit, much improved by cultivation, as the Cujavus domestica. ‘There are a great many varieties, of both colours and forms, that have an excellent flavour, and must be considered as belonging to the latter. In India, although an exotic, the Cujavus agrestis, like the Pyrus malus in Scotland, has become a perfect forest or wood tree, the seeds having been scattered by birds, as they powerfully resist the organs of digestion. Cujavus silvestris, p. 144. Probably a variety of the Cujavus agrestis. Carut XLILII. Cujavillus, p. 145, t. 49. Burman, in his Flora Indica (114), called this Psidium cujavillus ; but it was unnoticed by Linnzus. The Com- pilers of the Encyclopedie received from M. Sonnerat spe- cimens of a plant, which they called Psidium angustifolium, as synonymous for which they quoted the cujavillus, with, however, some doubt. Vahl, as usual, changed the name of Burman into Psidium pumilum, quoting, without hesi- tation, the cwjavillus for the plant he meant. Willdenow prefers the name of Vahl to both that of Burman and that VOL, V. Z 354 COMMENTARY ON of the Encyclopedie, and quotes both without any doubt of the plants they describe bemg the same; yet I suspect that the plant of Rumphius. is not different from the Psi- dium decaspermum of Willdenow (Sp. Pl. 1. 958), which Forster considered as a distinct genus, in which he is sup- ported by Gertner, the former calling it Decaspermum /ru- ticosum (Gen. Nov. N. 37), and the latter Nelitris jambc- sella (De Sem. 1. 135, t. 27, f. 5). Caput XLIV. Papaja Mas et Femina, p. 145, t. 50, 51. Ever since the time of Linnzeus this plant has been called Carica papaya; nor does any commentary seem to be required. Papaja silvestris, p. 149, t. 53, f. 1. This is quoted by Willdenow (Sp. PI. i. 549) as the Bergera Koenigii; but I agree with the Compiler of the Encyclopedie (Sup. 1. 620) in thinking them very different plants. From the description of the fruit in Rumphius, “¢ post flosculos sequuntur fructus, qui pallide et rotunde sunt baccee, minores granis Oryzz, superius planze, ibique formantes coronulam ex quinque filamentis reflexis compo- sitam, ac ipsis baccis plane incumbentibus, in qua albicans siccaque locatur medulla in quinque loculos divisa,” I in- fer, that the fruit is “ bacca pentasperma, calyce penta- phyllo coronata ;” which, together with its habit, persuades me that the plant belongs to the order of the Aralic. Papaja litorea, p. 150, +t. 52. This also seems evidently to me to be a plant of the or- der of Araliz, and M. Poiret (Ene. Meth. v. i) considers it as a species of Panax; but this seems doubtful, as no- THE HERBARIUM AMBOINENSE. $55 _ thing is said in Rumphius, the only authority, to enable us to determine its genus. Papaja Atehu, p. 150, t. 53, f. 2. This also is evidently one of the Aralix; and, if it has really eight petals, as Rumphius says, it is probably a Gastonia; but it is possible that his “octo petala” may include the divisions of the calyx, as well as those of the - corolla. Carut XLV. Lansium domesticum album et rubrum, p. 151, t. 54. Mr Correa, according to the Encyclopedie (Sup. 11. 299), considers this as nearly allied to the Cookia, in which I _ entirely coincide. It differs from the Cookia in having the seeds covered by a succulent arillus. It seems also to have a considerable affinity with Nyalel of the Hortus Malaba- ricus (iv. 37, t. 16); which, however, has its flower divid- ed into five, and only two seeds in each berry. ‘The two kinds mentioned by Rumphius seem such varieties as occur in all cultivated plants. Carut XLVI. Lansium silvestre primum et secundum, p. 153, t. 5d. Rumphius gives no mark, except the colour of the wood, by which these trees could be distinguished, and this will scarcely be accepted by botanists: nor does he mention to which his figure belongs. Lansium montanum, p. 154, t. 56. No reference is made to this plant by any author that I know. z 2 856 COMMENTARY ON Carut XLVII. Cussambium, p. 154, t. 57. In the observation annexed to this chapter, Burman compares the Cussambium to the Pongam of the Hortus Malabaricus (iv. ‘73, t. 35). The Compilers of the Ency- clopedie (ii. 235) admit a certain resemblance, but point out the remarkable difference in the structure of their fruits. I must say that I see no resemblance; for the leaves of the . Pongam are simple, and those of the Cussambium are pin- nated: the former probably belongs to the Urticee, and the latter to the Terebintaceze. I have found the name Kusam very widely diffused in India, and applied in Kankana in the southern peninsula, and in Magadha on the Ganges, to trees like the Cussambium, having a very hard heavy timber, alternate abruptly pinnated leaves, small flowers disposed in racemes, and a drupa containing one nut. This genus approaches to the Schinus, but the structure of the drupa is very different, the nut almost entirely resembling the Koon of Geertner (De Sem. i. 486), which he takes te be an Ochna; but, as he never saw the nuts united, we may suspect a mistake. Besides the plant of Rumphius, which I have not seen, I have observed two species of this genus, and I thus distinguish the three: 1. Cussambiam spinosum drupis spinulosis, Herb.

This seems evidently to be a Cussambium, very nearly allied to my C. glabrum, above described, if it be really different; but being cultivated, its fruit is probably more succulent than that which grows wild in India, although this also is esculent. Carur XLVITI. Pomum draconum domesticum, p. 157, t. 58. This seems pretty clearly to be a Spondias, but it is not mentioned by any recent author, so far as I know. Carur XLIX. Pomum draconum silvestre, p. 159, t. 59. This also seems to be a Spondias. “4 Rau Genrang, p. 159. Seems to be still another Spondias. Carut L. Condondum, p. 161, t. 60. In a commentary on the First Part of the Hortus Mala- baricus, I have explained several errors that have arisen THE HERBARIUM AMBOINENSE. 359 from that of Rumphius in confounding the Condondum with the Ambalam, and from the erroneous synonyma given in the observation of Burman. While the Ambalam is clearly a Spondias, I have little doubt of the Condondum being the Mangifera pinnata of the younger Linnzus,, of which I have presented a specimen to the Company’s col- lection. styl o Carut LI. Condondum Malaccense, p. 162, t. 61. Whether or not this be the same with the Cat ambolam of the Hortus Malabaricus (1. 93), as Burman in his ob- servation asserts, I cannot say, as the account of the Caé ambolam is remarkably imperfect; but the plant here de- scribed by Rumphius seems clearly to belong to the same genus with the Mangifera pinnata, quite different from a Spondias; nor can I perceive any thing, except the leaves, to distinguish the Condondum from the Mangifera indica. Capour LIL Cynomorium, p. 163, t. 62. This was called Cynometra by Linneeus, and subsequent authors have adopted the same name, although not a little objectionable. Carut LILI. Cynomorium silvestre, p. 167, t. 63. Linneeus, following the observation of Burman, joined this with the Iripa of the Hortus Malabaricus (iv. 65, t. $1), to form the Cynometra ramifiora ; and as usual has been followed, without comment, by more recent writers. I am very doubtful, however, concerning the identity of 360 COMMENTARY ON these plants; for the leaves are described by Rumphius as very acute, ‘ folia longiora, magisque acuminata ;” while those of the Iripa are blunt, “ oblongo-rotunda;” and, in the figure, appear as if even retuse. In Ava I found a tree called Mreen-ga, which agreed with the specific cha- racter of the Cynometra ramiflora, as given by Linnzus; but I did not compare it with the figures and descriptions of the two great Indian botanists. Specimens, however, were transmitted to Sir Joseph Banks, and may serve to throw more light on the subject. : Caput LIV. Sandoricum domesticum, p. 167, t. 64. The Compiler of the Encyclopedie (iii. 69), copied by Willdenow (Sp. Pl. u. 556), quoted this, with doubt, as being the same with the Hantol of Camelli and Ray, which the French botanist called Sandoricum zndicum; but it must be observed, that the figure of Rumphius represents © the flower without any thing like the cylindrical nectarium, which in the Hantol supports the antherse. No great stress can, however, be laid on this circumstance. Sandoricum silvestre, p. 168. Whether this is a distinct species from the preceding, or whether it is merely the plant in an uncultivated state, I cannot take upon myself to determine, although I think that I have seen the plant in Pegu; but unfortunately, like the specimen of the Sandoricum indicum, which the French botanist procured, the trees which I found were in fruit. In the language of Ava it is called Sit-to, and spe- cimens were sent to Sir Joseph Banks. At the time I con- sidered it as nearly allied to the Crateeva fapia, which, with THE HERBARIUM AMBOINENSE. 361 Dr Roxburgh, I then called a Capparis. The following note I took on the spot. Arbor ramis teretibus, pubescentibus, fuscis, elevato-puncta- tis, sulco e petiolorum basi decurrente utrinque exaratis. Folia maxima, alterna, petiolata, ternata; foliola _ petiolata, integra, integerrima, supra nitida, subtus tomentosa, venis reticulata, plana; lateralia oblonga, acuminata, ad basin posterius gibbo- siora ; terminale latius, obtusum. Petiolus communis mediocris, ey versus incrassatus, apicem versus semiteres, pubescens: partialium Jaterales brevissimi; terminalis mediocris, teres, utrinque incrassatus. Stipule nulle. Pedunculus fructiferus axillaris, solitarius, fructu terminali indivisus, rudimentis quasi flosculorum abortivorum plurium lateralium notatus. Bacca supera, calyce deciduo nudata, glo- bosa, striata, corticosa, unilocularis. Nucicule quinque.pulpo filamentoso arillatz. From this it would seem that it differs from the descrip- tion of Willdenow, in having the flowers disposed in un- divided racemes, or perhaps spikes, while his plant has panicles. Cajim-gulur, p. 168. This may be another Sandoricum. Carut LV. i Gajanus, p. 170, t. 65. By Thunberg and Willdenow (Sp. Pl. 11. 604) this was considered as the Inocarpus edulis of the younger Linneus ; but the Compiler of the Encyclopedie (11. 576, and i. 253), on account of the form of the fruit, as represented by Rumphius, doubted of the accuracy of this quotation, and considered the tree as related to the Aleurites, or Euphor- biz. On farther consideration, however, it would seem that the Compiler was satisfied of the quotation having been proper, as he repeats it in the Supplement (im. 151). 362 COMMENTARY ON I must notwithstanding say, that the figure of Rumphius has little or no resemblance to that of the Inocarpus eduhs given by Geertner (De Sem. iii. 114, t. 199, 200), and still less to that given in the Encyclopedic (Ill. Gen. t. 362). I suspect therefore some mistake, and this perhaps in the figure of Rumphius, which in some respects does not agree with his description ; for he says of the fruit, “forma lunz crescentis,” which agrees somewhat with that of Geertner, but by no means with that in the Herbarium Amboinense. Burman in his observation seems totally wrong in compar- ing either description or drawing to the Tani of the Hor- tus Malabaricus (iv. t. 10), which is no doubt a Terminalia, or Myrobalanus. Carut LVI. Atunus, p. 171, t. 66. The Compiler of the Encyclopedie (1. 329), in mention- ing this tree, does not venture to point out its place in the system. If it belong to the same genus with the Atunus hitorea (ui. 95), I suspect that it may be a Niota, as I shall endeavour to point out on a future occasion. Atun Puti, p. 172. This has pinnated leaves, while the preceding tree has them simple. They probably therefore belong to different genera. is Carvut LVII. Vidoricum domesticum, p. 173. Vidoricum silvestre primum, p. 173, t. 67. These trees probably belong to the same genus; and if Gertner (De Sem. i1..105) is right in considering the Vi- THE HERBARIUM AMBOINENSE. 363 doricum sylvestre secundum (Herb. Amb. in. 184) as a Bassia, these also may belong to the same genus, although they also strongly resemble the genus Diospyros; but to this subject I shall again have occasion to return. I need scarcely mention that Burman, in his observation on this plant, is totally wrong in considering it as of the same ge- nus with the Caniram of Rheede (Hort. Mal. i. 67, t. 37), which is the Strychnos nua vomica. Caput LVITI. Catappa domestica, p. 174, t. 68. Why Linnzeus chose to give the name Terminalia to the genus to which this tree belongs, Rumphius having previ- ously applied it to a totally different plant; and why, still farther, he did not give even the specific name catappa to the same tree that Rumphius called so, xa’ sox, I cannot say; but this is not the Terminalia catappa, nor does Lin- nzeus seem ever to have seen it. M. Lamarck (Enc. Meth. i. 349) seems first to have introduced it into the modern system of botany, under the name of ‘Terminalia moluccana, a name properly retained by Willdenow (Sp. Pl. iv. 968), although Forster had called it Terminalia glabrata; and Dr Roxburgh, probably in a private communication to Willdenow, had given it the name of Terminalia elandu- losa. My worthy friend, however, before his death, adopted the name of Lamarck (Hort. Beng. 33). Catappa litorea, p. 175. - Seems also no doubt to be a Terminalia. Catappa silvestris, p. 175. This, I have little doubt, is the Terminalia catappa of botanists, the Ada maram of Rheede (Hort. Mal. iv. 5), 364 COMMENTARY ON because Rumphius states as follows :—< Ore foliorum an- gustate fere ad petiolorum ortum, qui obducti quoque sunt tenul, rufa, et molli lanugine, quali itidem ramuli virides surculique obteguntur.” The kernel, however, in the plant of Malabar, probably from cultivation, is superior in size to what it would appear to be in the wild plant of the eastern islands, fully equalling what Rumphius describes that of the Catappa domestica to be. ‘The leaves, so far as I have observed, are quite entire, so that the only difference be- tween the plants of Malabar and Molucca arises from the leaves of the former being hairy beneath, while im the latter they are smooth. The resemblance to this fruit mentioned by Plukenet (Mant. 156, cum Alm. 306 collata) appears to me far-fetched, and, notwithstanding the author’s pru- dery, could only have arisen from a prurient imagination. Caput LIX. Cassuvium, p. 177, t. 69. This plant, originally a native of America, has now spread itself, through most warm countries, in sandy places near the sea; but, in India at least, is seldom found in _ other situations. Its origmal name, Acajou, variously writ- ten and corrupted, seems to have followed the tree every- where, and is known in Old India, the Eastern Archipelago, and China. ‘The name Kapa Mava, given to it in the Hortus Malabaricus (au. 65, t. 54), I never heard among the natives of Malabar, and suspect some mistake in Rheede. Caspar Bauhin considered this tree as of the same genus with the Anacardium of the East, and therefore most pro- perly called it Anacardn alia species. Linnzus, who knew no other kind, in imitation of Bauhin, called the West In- dian plant Anacardium occidentale; but his son, having | THE HERBARIUM AMBOINENSE. 365 obtained the original Anacardium of the East, and, finding some slight difference in the number of the sexual parts, made it a distinct genus; while, in place of reserving for this the name Anacardium given to it by the earliest bota- nical writers, he called it Semecarpus. Although this no- menclature is adhered to by Willdenow (Sp. Pl. i. 1476, et 11. 486), and many other most eminent botanists ; yet, if the plants are to be considered as belonging to different genera, I must prefer the nomenclature adopted by La- marck, followed by Jussicu and other French writers, who have restored the name of Rumphius to the Anacardii alta species of Bauhin, and the name Anacardium to the plant originally so called. As, however, I consider that both plants belong in fact to the same genus, I would call the former Anacardium cassuvium, and the latter Anacardium _semecarpus. Carut LX. Cassuvium silvestre, p. 179, t. 70. Willdenow does not quote this plant; but in the Ency- clopedie (i. 140) it is considered as a variety of the Ana- cardium longifolium, which Willdenow calls Semecarpus anacardiwm (Sp. Pl. i. 1476). Dr Roxburgh, on the con- trary (Hort. Beng. 22), having procured plants from the Moluccas, considered it as a distinct species, which he called Semecarpus cassuvium ; nor, indeed, did Rumphius sup- pose that his plant was the Anacardium of the shops, the nuts differing very considerably, in shape at least, being reniform in the Cassuvium silvestre, while in the Anacar- dium orientale they are ovate, with a slight notch, on one side, under the point, which is oblique. In India there is still another species very nearly allied to the Anacardium orientale, and in fact confounded with it by the natives under the common name Bhela of the 366 COMMENTARY ON Hindwi and Bengalese lancuages, and San-bho Sa-reek in that of Ava. This want of distinction 1s of no great con- sequence, as both species possess the same qualities; nor in this respect would the plant of Rumphius appear to differ in any material point. J shall, however, give an account of this third species, hitherto little known, although in the woods of Gangetic India it is a very common tree. — Anacardium cuneifolium foliis obovatis, subtus tomentosis.

Botanists have usually quoted these as forming only one species; and, as the tree is cultivated, and thence probably assumes different appearances, this may be the case, the male and female kinds, as Rumphius calls them, bemg what recent botanists call varieties: for they are not, as Jussieu supposed, the male and female of a dioicious plant, as both produce fruit. Burman, in his observation on this plant, has confounded it with the Mala elengi of the Hor- tus Malabaricus (v. t. 55), which I consider as being a Chionanthus. Linnzeus, taking Gnemon for a specific ap- pellation, called it Gnetum, in which he has been followed by subsequent writers, although I am at a loss to know from whence he took the word. ‘The synonyma quoted by Rumphius himself are more correct than those given since, this plant having been brought early into notice by Sir Francis Drake, who found it on the island Beretina, from whence it was called Fructus beretinus. It was afterwards introduced into the botanical system by C. Bauhin, under the name of Laurifolia terenatensis ; and it seems surpris- ing that these synonyma should not have been quoted by moderns. . Carut LXII. Gnemon silvestris, p. 183, t. 73. This is the Gnetum ovalifolium of the Encyclopedie (Sup. 1. 810). The plant of the Hortus Malabaricus (v. 51, t. 26) called Mail Ombi or Kombi, which Burman thought the same with this, is probably an Antidesma. 368 COMMENTARY GN Capur LXITILI. Morunga mas, p. 184, t. 74. Morunga femina, p. 184, t. 75. Some confusion here exists in the account of Rumphius ; for he says, ‘“‘ Flores maris omnes pereunt, nec fructus re- linquunt ; feminee autem flores excrescunt in ingentem si- liquam ;” from which we ought to infer, that the tree is dioicious: but in the plates both male and female are re- presented as producing fruit ; and besides, from their leaves, the plants sc called would appear to be different species, although in the description no notice is taken of this differ- ence. The older botanists noticed only one kind of Morunga, as is especially the case with Rheede (Hort. Mal. vi. 19, t. 11). Several of these authors noticed the resemblance of this plant to the Balanus myrepsica, or Nux Been of the druggists, although im general they mentioned an essential difference in its having winged seeds. Plukenet (Alm. 253) commenced a system of error respecting this plant, by con- sidering it as the same with the Lignum nephriticum of America, an opinion which the Compiler of the Eneyclo- pedie (Sup. i. 659) properly rejects; for the wood of the Morunga gives no blue colour to water in which it is in- fused. The elder Burman endeavoured to establish two species of Morunga; the Morunga mas of Rumphius he called Moringa Zeylanica, pinnis rarioribus, flore minore (Thes. Zeyl. 164), distinguished by having only five stamina: while the Morunga femina of Rumphius he called Moringa Zeylanica, flore majore, fructu anguloso (Thes. Zeyl. 162, t. 75), distinguished by ten stamina. The character de- rived from the number of stamina, could we depend on the © accuracy of Burman, would be excellent; but in the plant THE HERBARIUM AMBOINENSE. 369. so common about the villages of India, although there are ten filaments, five only of them have anthere, as described. by Rheede, “ colus in decem staminula e viridi albula ex- trorsum flexa, divisus, quorum paria (sing wla éntellige) uno grandiusculo flavescente obteguntur apice :” and it is pos- sible that Burman may have thought that some of the: an- therze had fallen by accident from his specimen, and that in their natural state all the filaments were fertile. I have,, however, séen two kinds of this tree, one growing near vil- lages, and the other in woods, and answering to the Wattu (hortensis) Murungu, and Katu (sylvestris) Murungha of. the Ceylonese; and, as I have not seen the flowers'of the kind growing spontaneously in woods, it may have only: five filaments, as Burman describes: I shall, however, eoune return to this distinction. _ Linnzeus, in the Flora Zeylonica (155), not only adopted: the error of Plukenet, im considering the Moringa as the same with the Lignum nephriticum ; but still farther, he considered it, not only as belonging to the same genus with: the Balanus myrepsica or Nux behen, but as being the same plant, an error from which Plukenet escaped. How Linnzeus came to place the Moringa in the same genus with the Bonduc of preceding authors, I cannot say; as, in my. opinion, notwithstanding his eminent authority joined to that of Jussieu, I must agree with Gertner in thinking that it cannot belong even to the same natural order (Le- guminose), but seems to- approach nearer to the Rutaces:; although even this arrangement is'not satisfactory, and it seems. to belong to a genus rejecting a close affinity with all. others. The error of Linnzeus, in joming the Moringa with the Bonducs, to form the new genus. Guilandina, having: be- come evident, Jussieu and other French botanists have most properly restored the name Moringa given by John VOL. V. A@ $370 COMMENTARY ON Bauhin. Neither this, however, nor the still more simple Anoma of Loureiro, has satisfied the modern taste for ses- quipedalian Greek, from which Vahl and others have given us Hyperanthera,—a term applied by Forskal. to a genus, which I suppose is very different, being really ene of the Leguminose, with a calyx of one leaf, and a fruit consist- ing of two valves, to one edge of which the seeds are an- nexed ; while in the Moringa there are three valves, sup- porting the seeds by their middle.. Excluding the two spe- cies, which properly belong to the Hyperanthera of Fors- kal, or to the Gymnocladus of Lamarck, we shall have in Willdenow, as well as in Rumphius and Burman, two spe- cies of Moringa. Loureiro has also: two species, a Moringa and a Morunga; but the latter, although jomed by the Compiler of the Encyclopedie (Sup. i. 391), and by Will- denow, with the Morunga of Rumphius, having opposite leaves, must be a totally different plant. ‘The synonyma, imdeed, annexed to the Hyperanthera moringa by Willde- now, belong to four, or perhaps rather to five, different plants ;. and those referred to the Moringa oleifeéra in the Encyclopedie G. 398), refer to two or three; and. I find it impossible to say which of these plants were really meant.. Both authors include the two species of Rumphius, te which the Encyclopedie adds a plant of Egypt and Arabia, the Balanus myrepsica, or Glans unguentarius of old writers (the Moringa aptera of Gertner, De Sem. ii. 315); and Willdenow still farther adds, the American: Lignum pere- grinum aquam ceruleam reddens of Bauhin, by severals. called Lignum nephriticum, and the Anoma morunga of Cochinchina, described by Loureiro, and in the Encyclo- pedie (Sup. i. 391), as having opposite leaves. ‘Now, to return to the Morunga mas et femina of Rum- phius ; neither of which, I am persuaded, grows naturally in Egypt nor America, and which, if not distinct species, THE HERBARIUM AMBOINENSE. 371. as Burman supposed, are at least remarkable. varieties. The only reason, I suppose, which Willdenow had for stating that this species belongs to the class Polygamia di- cecia, consisting of two different kinds of hermaphrodite plants, was the confounding the two species of Rumphius together. With much more reason he would have referred the Morunga femina to his Hyperanthera decandra, which, he says, has ten fertile stamina, as Rumphius represents in his figure, and this is the very character by which Burman distinguished it from the Morunga mas. In the Supple- ment to the Encyclopedie this change has accordingly been made; but then the Anoma moringa cannot be the Gui- landina moringa of Linneus, which is not the Hyperan- thera decandra, but the Hyperanthera moringa. Like Rumphius and Burman, as has already been men- tioned, I have found two kinds of this plant. Perhaps the differences between them arise from the one being cultivated, and the other remaining wild ; but this remains to be ascer- tamed: and I am not able to verify whether or not the wild kind be the Hyperanthera decandra, as I did not see the flowers. I am by no means satisfied that either is the Morunga femina of Rumphius; for I do not think that I have ever seen a species with leaves so regularly bipinnated. I shall, however, mention what I have observed concerning the two species or varieties which L have seen. I reject the specific name pierygosperma, given by Gertner, because _ he includes both species of Rumphius, and it is impossible to say which he meant. 1.

Although I have quoted Rumphius with doubt, because his figure represents the small leaves (foliola) as sharp- pointed, and the leaves as abruptly pinnated, yet every thing he says respecting the growth, cultivation, and uses of the plant, as usual, is excellent, and applicable to the plant I have described. I do not quote Linnzus, the younger Burman, Willdenow, nor the Encyclopedie, be- cause several plants are included by each among the syno- nyma of the Guilandina moringa, or Hyperanthera mo- ringa, or Moringa oleifera, and it is impossible for me to determine which they really meant. I do not quote either plant of the elder Burman, because his second plant (‘Thes. Zeyl. 164), which he considers as the same with the Mo- ringa mas, is said to have a small flower, which would not appear to be the case with that of Rumphius; nor is it the THE HERBARIUM AMBOINENSE. 378 ease with my plant. Farther, his first plant (Thes. Zey]l. 162) is said to have ten stamina, all of which in the figure are represented as provided with anthers; and, besides, the figure is a very bad representation of the plant which I have described. I have, however, very little doubt of this being the Wattu or garden Moringa of the Ceylonese, as in every part of India it is the plant most common about villages. 2.

Its fruit is too bitter to be eaten in curries, as that of the domesticated species is; and is used only as a medicine. Having very strong sensible qualities, it proba- bly possesses considerable power on the human body; and was probably that used by the Dutch physicians in Ceylon (Burm. Thes. Zey]. 164), although some parts of even the cultivated kind would seem to afford a valuable medicine. Carut LXIV. Turia, p. 188, t. 76. In a Commentary on the Hortus Malabaricus (i. 93), when treating of the Agaty, I have mentioned the botani- cal history of this plant, which is the same. As Rumphius says, that the Malabar name is Abati, we may conclude that either Agaty or Abati is a typographical error. In the observation following this chapter, Burman is quite 374 COMMENTARY ON wrong in considering this as the same with the Kedangu of the Hortus Malabaricus (vi. 49, t. 27), which has flowers not larger than those of the bean (Faba). Turia rubra, p. 189. This is probably a mere variety, such as usually takes place in plants that are much cultivated. At one time I thought that it might be the Aischynomene, or Coronilla coccinea (Willd. Sp. Pl. ii. 1146); but that being the Tari mera of Rumphius, is a sufficiently distinct species, which I have never seen. I suspect that in reality Willdenow fell into a similar error, as he says, ‘ simillima preecedenti (Coronillz grandiflore). Flores ejusdem magnitudinis sed rubri:” but Rumphius, treating of the Teri mera, says, “¢e rachidis ala petiolus excrescit in binos sese dividens minores, quorum quisque ingentem gerit florem paulo mi- norem quam preecedentis, id est C. grandifiore.” Turia striata, p. 189. This is probably another variety of the same elegant tree, with variegated flowers, not very common in India. Toeri mera, p. 190, f. 77. In treating of the Turia rubra, I have noticed this plant, which, by Forskal and the younger Linneeus, was called ffischynomene coccinea. Burman in his annotation is to- tally wrong in considering this as the same with his Emerus siliguis geminatis longissimis (Thes. Zeyl. 93, t. 41), which, I have little doubt, is the same with the Kedangu of the Hortus Malabaricus, and has not scarlet flowers. THE HERBARIUM AMBOINENSE. 875 Carut LXV. Olus album domesticum, p. 191, t. 78. Burman (Obs. p. 192) seems quite right in considering this as the same with the Bem manja of Rheede (Hort. Mal. v. 113, t. 57). The name Naravolo, which, according ‘to this author, the Brahmans of Malabar give to this tree, I found to be the name given in Carnata to a species of ‘Cordia, called angustifolia by Dr Roxburgh (Hort. Beng. 17); but the two plants seem to have no affinity. It is singular that neither of our two great Indian botanists saw ‘either flower or fruit of this tree. The leaf seems to have some reserablance to the Acacias folio conjugato pinnato ; but this is all the resemblance that I can trace; and the Compiler of the Encyclopedie, who mentions Rheede’s ac- count (Sup. i. 613), gives no conjecture concerning its affi- nities. Neither is Plukenet, who mentions the tree (Alm. 66), more explicit; and he quotes Ray, who also describes it as producing neither flower nor fruit: but this excellent botanist, in callmg the leaves alata, supports the opinion of its being an Acacia; although what I shall observe on the following plant seems to contradict this opinion beyond a doubt. Carur LXVI. Olus album insulare, p. 193, t. 79, f. 1. The leaf of this has still more resemblance to that of an Acacia than that of the preceding plant, there being evi- dently a large gland on the common petiolus; but the de- ‘scription of the flower and fruit seems irreconcileable with this opinion, and the description of Rumphius would seem -to imply, in the Linnean phraseology, ‘“ calyx superus, quinquifidus. Petala alba. Stamina octo vel.decem. Drupa sicca, ovata, pilosa, venosa.” 376 COMMENTARY ON Utta Pela seu Sajor Bagnala, p. 194, t. 79, f. 2. Linnzus confounded this with two American plants of the same genus, which Plumier called Plukenetia. These were finally separated by Smith, and the plant of Rumphius is now called Plukenetia corniculata (Willd. Sp. Pl. iv. 515; -Enc. Meth. Sup. v. 20). Caput LXVII. Eriophoros Javana, p. 195, t. 80. Pliny mentions two different plants that contain in their fruit a wool fit for clothing. The one (lib. xu, cap. 10, 11) he calls Arbor gossampinus, the other he calls (lib. xix, cap. 1) Frutex gossipion, forming thus two natural genera; and as botanists have usually written in Latin, they should have preserved the names thus judiciously given by their Roman precursor. I agree with Rumphius in thinking that the Arbores Gossampini include the Eriophoros java- nica and several kindred species; while the Gossipion in- cludes the plants now in more common use for producing cotton-wool. The older botanists, such as C. Bauhin and Plukenet, considered all the plants producing cotton-wool as forming one genus, and preferred the name Gossipion; probably, however, judging themselves better Latinists than the Ro- man Consul, they changed this name into Gossypium, to which orthography their successors carefully adhere. Tournefort rejects the name altogether, and prefers Xylon, which indeed Pliny mentions as being a more common name than Gossipion, for the shrub bearing wool; and so far, therefore, the French botanist was entirely justifiable ; and so might even the elder botanists be held, who, con- sidering all the wool-bearing trees as belonging to one ge- nus, gave the classical name Gossypium to the whole. THE HERBARIUM AMBOINENSE. B77 _ Linneus was, I believe, the first to renew the idea of Pliny, in dividmg these plants into two genera: but in do- ing so, while he continued the term Gossypium for the ‘Gossipion of the Roman, he bestowed Xylon, another term for the same plant, to Pliny’s Gossampinus. This was in the earliest :part-of his course, when he published the Hor- . tus Cliffortianus and Flora Zeylanica. Soon after he seems to have become sensible that the term Xylon was ill-applied to the Gossampinus of Pliny, and he therefore abandoned it im the first edition of the Species Plantarum; but, in place of restoring the name of Pliny, or adopting Eriopho- ros used by Rumphius, or Ceiba applied by Plumier to plants of the same genus, he used the word Bombax, of ‘which I do not know the origin. It has, however, been adopted by all modern botanists, except Gertner, who might perhaps have been justified in resuming the Gossam- pinus of Pliny; but the Bombax of Linnzeus is surely as good as the Ceiba of Plumier. Perhaps the Bombax of Linnzus should be left to one of the species earliest de- scribed by him, the Bombax gossypinum or conga, which is quite different from the others, does not belong to the ‘same natural order, but rather to the Tiliacese, and is not an Arbor lanigera. In this case, the classical name Gos- sampinus should be restored to the other species of Bom- bax, the authority of Gaertner being scarcely sufficient to introduce Ceiba. _ Rumphius, and the elder Burman in his annexed obser- vation, seem to have considered the Eriophoros javanica as being the same with the Pania or Paniala and Moul Elavou of the Hortus Malabaricus (iu. 59, t. 49, 50, 51, et 61, t. 52); but this is evidently a mistake, as the sta- mina of the Moul Elavou distinguish it clearly from the Eriophoros Javanica. The Pania was quoted by Plukenet (Alm. 172) as his “* Gossipium seu Xylon arbor Orientale 378 COMMENTARY ON digitatis foliis levibus, fructu quinquecapsulari, aloa et ni- tente lanugine farcto;” but unless the figure (Phyt. t. 188, f. 4) be very bad, he must have been mistaken, as it repre- sents numerous stamina; on which account, his plant is quoted by Willdenow for the Bombax heptaphyllum, al- though in other respects it has but little resemblance to that tree. The synonyma, however, which Plukenet gave, probably all belong to the Pania or Eriophorus Javanica, although he quotes the former erroneously, as if Pania Paniala had been one name, an error copied by several subsequent writers. Linnzeus, in the Hortus Cliffortianus and Flora Zeyla- nica, endeavoured to distinguish the species of this genus by the presence or absence of prickles on the stem; and indeed Rheede takes no notice of the prickles on the Pania, while he mentions these of the Moul EHlavou, the very word Moul implying prickles. Linnzeus, however, soon afterwards learned, that the stems of the younger trees of the Pania are prickly, as is stated by Rumphius; and he therefore had recourse to other distinguishing marks, with- out, however, altering the synonyma, which his former de- fective characters had induced him to adopt, in considering two American trees as the same with the two plants of Asia, because one had a smooth, and the other a prickly stem. Carut LXVIII. Bilacus Tellor, p. 167, t. 81. Into the explanation of either this or the following plate some error has crept. The fruit represented at A is said to be that of the Bilacus taurinus, but this again is said to be represented in plate 82. The fruit marked B is said to be the Bilacus ovalis or tellor, and the fruit C is said THE HERBARIUM AMBOINENSE. 379 4o be that of the Bilacus minimus or Kitsitl; but no such species is mentioned in the text: and the third kind de- scribed there is the Bilacus Pissang, which, as Rumphius “says, ‘ nomen obtinuit ab oblonga forma instar. Muse Pi- -sangh dicte ;” but the fruit C is shaped like a pear, and cannot represent such a Bilacus, as is described. ‘These three fruits, I think, represent three varieties in form of the Bilacus tel/or, which may indeed be called maximus, -ovalis, and minimus ; but these are merely such varieties as occur 1n all cultivated plants; while the Bilacus tawrinas, if it be represented in plate 82, and Bilacus Pissang, are probably distinct species. On this subject, however, I must, for a farther account, refer the reader to the Commentary on the Bilacus taurinus. The Bilacus ¢ellor and its varieties were early noticed by ‘Dotanists under the name Marmelos, corrupted from the “Marmeleira of the Portuguese, given to it because this people seem to have prepared a marmalade from its fruit ; on which account the older botanists compared it to the Cydonia, a tree resembling it in no other respect. In the Hortus Malabaricus (in. 57, t. 37) it was described under the name Covalam; but the commentator, Commeline, still adhered to the shght resemblance with the Cydonia. Plukenet seems to have been sensible of the absurdity in _this comparison ; but he was little more fortunate in calling it “ Cucurbitifera trifolia, spmosa, Indica, fructus pulpa Cydonii zmula,” (Alm. 125; Phyt. t. 170, f. 5). Now his Cucurbitiferas include Crescentia, Strychnos, and other plants equally dissimilar. The elder Burman (Thes. Zeyl. 84) continued to class it with the Cydonia, but gives the synonyma of preceding writers with sufficient accuracy. ‘In the Flora Zeylonica, Linnzeus was equally unfortunate with his predecessors, and united this plant with the Tapia of Margrave, which he supposed to be the Niirvala of the 380 COMMENTARY ON Hortus Malabaricus (iii. 49, t. 42), to form a new genus, which he called Crateva, the Nurvala being scarcely distinct from a Capparis, while the Bilacus belongs to the tribe of Aurantiz. Things respecting the Bilacus continued in this ‘state, only the name Crateva was changed into Cratzva, and the Bilacus was called Bilanus (Willd. Sp. Pl. 11.853), until Dr Roxburgh proposed that it should be called Cor- rea; but, another plant having obtained this name, the Bilacus by Persoon was called Aigle marmelos, the appel- lation that it still retains. In every part of India this tree is common. The natives of Ava call it Oush-shit; those on the banks of the Ganges, in the spoken dialects, call it Bel, corrupted from the Vilva cf the sacred tongue: but as the fruit is dedicated to the god Siva, it is usually called Sriphula, or the Sacred fruit. In the Hortus Bengalensis it is stated, that a variety, with a small fruit, is the Sriphula; and I have often heard the natives distinguish the Sriphula from the Bel; but on re- questing a Pandit, attached to my survey, to bring me the Sriphula, he brought me a fruit im shape and size exactly resembling that marked A im Rumphius. The fruit of this tree I shall here describe on the plan of Gertner, and this, I believe, will be new to the European botanist. Fructus obovatus, magnitudine ovi anserini, levis, glandu- loso-punctatus, odoratus, absque rudimento vel calycis vel stig- matis, apice subumbilicatus, parietibus lignosis crassis unilocu- laris, farctus pulpo subfarinaceo, fibris paucis intermixto, 10 seu 12 loculari. Loculi verticales, remoti. Semina in singulis loculis quina seu sena, uno super alterum posito, gelatino pauco pellucido tecta, ovalia, magnitudine pisi compressa, pilis longis involuta. Integumentum simplex, membranaceum, crassum, intus politum, ex embryone facile secedens. Perispermum nul- lum. Embryo forma seminis. Cotyledones crass, maxime, albze, hinc convexe, inde plane. Radicula parva inter cotyle- donum margines nidulans, nunc ad extremitatem, tunc versus Jatera posita. : THE HERBARIUM AMBOINENSE. 381 The kind called Bel by the Pandit was in flower, which was as follows: Calyx planus, parvus, quadrilobus. Petala quatuor, calyce alterna, oblonga, obtusa, patentia, crassa, ungue lato disco ca- lycino inserta. Filamenta plura, mdefinita, ibidem inserta, brevia. Anthere longitudine filamentorum lineares, quadri- sulce, acute, longitudinaliter ad latera dehiscentes, bilocu- lares. Germen pyramidale, tetragonum. Stylus brevis, teres. Stigma magnum, incrassatum, obtusum. From this having only four divisions in the flower, if this mark were constant, the Bel may be a distinct species from the plant of Rheede (Hort. Mal. ii. 37), described by Dr Roxburgh, which has five divisions in the flower, and which, the Commentator on the Hortus Malabaricus justly says, is the Sriphula (Scrifole) of the Bengalese, as this also has five divisions in the flower; and the same seems to. be the case with the Bilacus ¢ellor, to judge from the figure. ; The fructification of the variety of the Bilacus tedlor, with the large globular fruit, I thus described in Ava: Calyx inferus, persistens, planiusculus, quinque vel rarius quadrifidus laciniis ovatis. Petala quinque vel rarius quatuor zqualia, calyce multo longiora, revoluta, coriacea, oblonga, obtusa, sessilia, pellucido-punctata. Filamenta plura, ad basin quinquefariam approximata, hypogyna, subulata, patula, corolla, triplo breviora. Antherz patentes, lineares longitudine fere filamentorum. Germen receptaculo orbiculato insidens, ova- tum, octo vel decem sulcis exaratum. Stylus brevissimus, cras- sus. Stigma clavatum, apice obliquum, umbilieatum. Bacca globosa, parietibus lignosis intus pulpo farcta. Semina plura ovata, plana, sparsa, nidulantia, pilosa. From this it would appear, that, m this variety, the number of divisions in the flower is not fixed; and I am therefore led to consider, that a proper distinctive character cannot be founded on this circumstance. $82 COMMENTARY ON Bilacus Madia Pissang, p. 199. Whether this be a mere variety of the Auigle marmelos, or a different species, I cannot take upon myself to say. As I have already mentioned, the fruit C, in table 81, can scarcely have been meant to represent that of this plant, which has a fruit like that of the Musa, at least m external shape. : Carut LXIX. Bilacus taurinus, p. 199, t. 82 ? It seems strange that Rumphius should say, “ flores ig- noti mihi hactenus sunt,” and that, notwithstanding this, they should be fully represented in the 82d plate, which in the explanation is called Bilacus tawrinus. I am there- fore inclined to think, that the plate may represent the fol- lowing plant, the more especially as it has no thorns. In this case, the fruit A, table 81, as stated in the explana- tion of that figure, may, in fact, represent the Bilacus taw- rinus, which, on this supposition, would be a mere variety of the gle marmelos, and the most common form indeed, which this tree assumes in the Gangetic provinces; and, according to Rheede, it is the Slymappel of the Dutch, which 1s the Covalam of Malabar. It must, however, be confessed, that the interior structure of the fruit, as I have described it, agrees entirely with that of the Bilacus ¢ellor, as given by Rumphius; but not at all with that of the Bilacus ¢awrinus, which has only four or five seeds in each fruit, in which circumstance, also, it by no means agrees with table 82. Bilacus Amboinensis silvestris, p. 200, t. 82 ? For the reasons mentioned in the Commentary preced- ing, I suspect that this is the plant represented in table 82, THE HERBARIUM AMBOINENSE. 388 although the contrary is stated in the explanation of that plate. It seems, at any rate, to represent an Avgle differ- ent from the marmelos, and hitherto unnoticed in modern systems. P. §. In enumerating the synonyma of the Eugenia Jambolana, it escaped my notice, that it is the Caryophyl- lus aromaticus g of Burman (F1. Ind. 122). Since writing the Commentary on the Lansium domesti- cum, Mr Jack has published an account of this tree (Lin. Trans. xiv. 115), to which I beg here to refer; only ob- serving, that he classes it with the Melize, an order which requires much revision, as it depends on the flower alone. 384. ON THE ASCENT OF THE SPIDER XXI.—On the Power possessed by the Spider of propelling its Threads, and on the Ascent of that Insect into the Atmosphere. By Joun Murray, F.S.A. F.L.S. F.H.S. &c. &e: (Read 20th March 1824.) Ir the business of the entomologist be confined to the collection of a portfolic of butterflies, or the technicalities of mere nomenclature, we may consent to the praise of di- ligence and labour, but cannot approve the soundness of his views as a naturalist. Confined within these unenviable limits, entomology is but dull and unprofitable. - I do hold, however, that the entomologist may reason- ably assume higher vantage ground, and lay claim to nobler pursuits; and if the physiology of insects be taken into the estimate,—their curious structure and mechanism, —their habits,—their amusements,—their cares and sor- rows, the study expands in interest and importance. In this last pleasing department, Messrs Kirby and Spence have high claims on our grateful respect. After we have bewildered ourselves in computing the — movements and revolutions of those wondrous orbs that INTO THE ATMOSPHERE. 385 float in fearful sublimity in the boundless sky,—marvelled at their mighty structures, and wandered wearily from planet to sun, and from star to star, till we have been lost in the exceeding majesty of the scene, it is refreshing to the exhausted spirit to descend from the celestial excursion, and join the ranks of the botanist, or the entomologist, and to feel assured that the goodness of the Drtry has not been exhausted on those unmeasured worlds, but that his beneficence is extended to the lowest of his creatures. Among the varicus phenomena presented to the research of the entomologist, there does not seem one more curious and interesting than the ascent of the wingless Spider into the atmosphere,—a fact unquestionable and unquestioned. It is one, however, recorded without a solitary attempt to- ward its solution. I have consulted authorities in vain; _ among others, Linnzeus, Shaw, and Donovan. The gossamer-web was formerly believed to be a tissue of “scorched dew ;” hence Spenser— The fine-net which oft we woven see Of scorched dew. Even Dr Hooke said that the gossamer only “ much re- sembled a cobweb,” and believed that “the great white clouds that appear all the summer time might be the same substance.” -Swammerdam and De Geer ridiculed the idea of the flight of spiders. Dr Hulse first observed the property which particular spiders possess, of propelling their threads into the air. _ Dr Martin Lister discovered that spiders were wafted aloft on this airy vehicle; and in fine weather (in Septem- ber) he found, more than once, a spider which, from its flight, he called “The Bird.” Afterwards, he noticed that the insect, by elevating the anus, darted a thread from thence, and thus rose into the atmosphere. VOL, V. Bb 386 ON THE ASCENT OF THE SPIDER From the highest point of the Cathedral of York, Dr Lister beheld the gossamer-webs floating far above him. | Mr White of Selborne confirms, by actual observation, Dr Lister’s account. He noticed a spider dart off from the page he was then perusing, and, though the atmosphere was tranquil, it rapidly ascended. _ It has been considered that this property is not peculiar to one species, but that several spiders, when young, can so elevate themselves. Mr White conceived that spiders in their transit through the atmosphere could coil up their threads, and descend ad libitum from their aérial excursions, altering in this manner their specific gravity. i I am not aware that any have attempted to describe the gossamer-spider as a distinct and peculiar species, Bechstein and Starck excepted; but they seem to describe different species. Thus the former describes it as being the size of a small pin’s head, having eight eyes disposed in a: circle; body of a dark-brown colour, and light-yellow legs. _ Starck describes his one as extending more than two lines in length, eyes in the form of a square, tw. on each side, in contact with each other; thorax of a deep-brown colour, with paler streaks; the under side of the abdomen of a dull white, and a dark copper-brown colour above, having a dentated white spot running longitudinally down the middle. | Dr Starck imprisoned: several of these under a bell-glass, on a grass-plat, and he tells us they existed two months without food, though they took water greedily. Mr White observed a remarkable phzenomenon on 21st September 1'741. Early in the morning the whole country” was: enveloped in a coat of cobweb, wet with dew. His dogs (being on a shooting excursion) were blinded by them. INTO THE ATMOSPHERE. 387 A delightful day succeeded. About 9 o’clock a. m. fell a shower of these webs, (not single threads, but formed of flakes), some nearly an inch Lsrbaedy and 5 or 6 inches long ; and such flakes continued to fall during the entire day. Baskets-full might be collected from the hedges; and from the velocity of their fall, it was evident that they were con- : siderably heavier than the medium through which they descended. The small spider with which these remarks are Loge ent has its eyes disposed in a circle somewhat elongated, .: the body and legs, examined with a lens, are hairy, palpi bifid, and protuberant at the end; tarsus forked or clawed; legs, &c. somewhat translucent ; abdomen and thorax glos- sy, and of a dark ferruginous colour; anal processes 9; the femur and tibia have each two articulations. Several of these spiders, included in a crow-quill, were transmitted to Professor Jameson. Those called ‘“‘ Money Spiders” by the reapers in some parts ef England, I pre- sume to be the same insect. The Reverend Mr Kirby writes me, that he thinks the Aranea obstetrix of Starck is that now spoken of: but the one described by Starck under this name is striped, and the eyes are arranged in the form of a square, which are sufficient distinctions. The subject of this communication approxmnates more nearly to Bechstein’s A. obstetria. I shall take leave to call it “ Aranea aéronautica,” be- cause, under the name Aranea obstetria the German natu- ralists describe two different insects; and I, moreover, be- heve Starck’s A. obstetrix to be (perhaps) the young of the Aranea geometrica, met with in hedges. 'The chief reason, however, for my proposing the assigned name, is the fact I have discovered, that its ascent and movement in the atmo- sphere are essential to its very existence. Bh2 388 ON THE ASCENT OF THE SPIDER I know well that the Aranea geometrica does possess the power of propelling threads into the atmosphere, and of thus changing its locality or making its escape; and perhaps, too, the young of this insect may possess the ‘power of taking an aérial excursion occasionally. Now, if so, I am persuaded it is a very rare event. The other is distinct and peculiar, and the numbers that occur in the atmosphere are such as sufficiently to account for the gos- samer, and its beautiful and interesting phenomena. It cannot therefore be doubted, that those threads which glis- ten in the sun-beam, and float in the air from the hedges and hedge-rows, and the reticular tissue on grass, which, when sparkling with dew, refracts so beautifully the tints of the rainbow, are the work of the aéronautic spider. As a proof that these wingless “‘ birds” are more numer- ous than may be generally suspected, I may merely men- tion, that, in the month of July 1822, on the top of the coach from Kidderminster to Stourbridge (a distance of only nine miles), there fell on me, or near me, thirteen aéronautic spiders, all of which I caught, and imprisoned in chip-boxes, which I carried with me for that purpose. This species of spider may be frequently met with in coach- offices, having alighted on the passengers, or on their lug- gage. : Connected with this question, I may mention a curious phenomenon that I witnessed on the 16th September last year, at Bewdley, Worcestershire. Between the hours of 11 «a. m. and 2 p. m. the whole atmosphere seemed to be-a tissue of cobwebs ; they continued to fall in great numbers, and in quick succession. ‘The temperature was 72° Fahren- heit. Some of these were single, others branched filaments, occasionally seen to extend from 40 to 50 feet in length. Others were woolly films, or flocculi. Some fell slowly, and others more rapidly. This was first noticed in the market- place, at Bewdley; and, on repairing to the adjoining fields, INTO THE ATMOSPHERE. 389 I found the same phenomenon, and my clothes were most curiously invested with a net-work of spiders’ threads. In a communication to the Reverend J. J. Freeman of Kidderminster, I remarked this circumstance; and the fol-. lowing is an extract from his letter to me, dated 18th Sep- tember 1822:—‘* The fall of cobwebs was also observed here on Monday.

So strongly and so conspicuously do the individuals composing this well-marked group resemble each other, not only in external habit, but also, for the most part, in intimate structure, that it is extremely difficult to establish genera, or subgenera, referable to it, upon well-grounded characters. Various ones have been proposed by the most eminent botanists, as, in the progress of their examinations, they have detected different situations, arrangements or directions, of the teeth of the peristome, or some other appa- rent peculiarity connected with the fructification. Thus we have Aplodon* of Brown, in the Appendix to Parry’s first voyage; also Cyrtodon+ of the same author, proposed in the observations under Aplodon in the same work ; both of which are removed from Splachnum. Mr Brown has also suggested that Splachnum Frelichianum and S. Wulfenia- num might with propriety form a subgenus, on account of their inclined capsule and erect teeth. In the present paper we have carefully examined almost every recorded species and variety in the Order; and though we do not pretend to any original discovery, we have endeavoured, by generalizing our observations upon well-crounded data, to establish our genera on what we con- ceive to be more tenable, and even more natural, characters. The whole has been done under the highest respect for the talents of those able botanists and philosophers who have conferred additional importance on muscology, by devoting their time and knowledge to its illustration. * This genus was formed to receive a single species, the Splachnum Wormskioldit of HorNEMANN. + This genus is composed only of Weissta Splachnoides of THunsERG and of Scaw&GRICHEN. Add NEW ARRANGEMENT OF It is necessary to state, that our views respecting the structure of the peristome are essentially the same as those which Mr Brown has so admirably detailed in the twelfth volume of the Linnean Transactions, p. 577, et seq. ‘That excellent muscologist has there expressed his opinion, that the semi-pellucid lines, or longitudinal striz, at least de- note a “ tendency to division in the teeth where they are found.” He also considers the prevailing number of teeth in the outer peristome of mosses to be thirty-two ; “ though, by a coalescence, more or less complete, they are frequently reduced to sixteen, in some cases to eight, and in a few even to four.” | ‘** According to this view,” continues the same learned author, “ a single longitudinal line in the axis of a tooth, indicates the confluence of two teeth; three equidistant lines, one being central, the coalescence of four; and seven Ines, similarly disposed, that of eight.” : ** Nearly the whole of these modifications exist in that natural subdivision of the order, which may be named Splachnee, consisting of Splachnum, Systylium, Tayloria, Splachnum squarrosum”™ of Hooxer, and Weissia Splach- noides.” : “The number of teeth in Splachnee is thirty-two; which, however, are never entirely distinct, and at the same * This plant has been subsequently published, and figured, by Dr Hooker, as Octoblepharum serratum. However, from the calyptra of O. albtdum be- ing dimidiate, it must now retain the name of Orthodon, given to the genus by Bory pe Sr Vincent. Mr Brown has drawn up its generic character in Linn. Trans. vol. 12. p. 597. As we have had occasion to notice this species here, we may take the epportunity to mention, that we do not conceive it to belong very satisfacto- rily to the Splachnoidee, and therefore we shall defer what we have to say concerning it to a future memoir. THE GENERA OF MOSSES. 4A time equidistant, but approximated or united in various degrees in the different genera and species of the section.” - _ As it is most desirable in every science, and especially in that of muscology, to have the technical terms well defined, and their meaning limited to their respective objects, we shall here explam what we hold to be signified by the terms, dentes geminati, dentes geminantes, dentes fissi, and dentes per paria approximati *. ‘The dens geminaius is a tooth which appears to be # single one, but which is marked by a longitudinal semi- pellucid line, denoting a tendency to separation, and often actually producing a separation; the line must therefore extend from the apex to the very base, and might be called with propriety the linea separabilis. 'There are thus ac- tually two teeth, which, when united, are called a once-ge-' minate tooth, and, when separated, two geminating teeth. The dentes gemimantes are a greater or less number of teeth longitudinally coalescmg, the number of teeth so united: being shown by the semi-pellucid longitudinal strize. The whole is called a tooth, which is farther characterised by bemg once, or twice, or four times, geminated. The dens fissus is not provided with a linea separabilis : * From the confusion that has been created in consequence of the want of a general understanding. on this point, the reader will readily concur in the necessity of a reformation of terms. The uncertainty of the present no- + menclature may be exemplified in a few words. Herpwic, ScuweGRicHEN, - and. others, describe the teeth of a Splachnum as “+ 8-geminatz.” Bripex, at - first, as “‘ 8-pariu,” and afterwards (as in S. Magellanicum), “ 16-gemznatz.”’ . While several authors apply ‘‘ dentes geminatz”’ to Splacknum,, they use the . phrase «© sedecem paria”’ to Systylium, and ‘* 16 per paria approximati” to . Zygodon and Orthotrichum, the structure of the teeth in all being the same.._ At the same time, also, “16 paria,” or ‘16 per paria approximati,” are, attributed to Didymodon, Trichostomum, and Leucodon, genera having a, péristome of a totally different nature. 446 NEW ARRANGEMENT OF it is a single tooth, cleft or divided more or less from the apex downwards, sometimes even nearly to the base; but at whatever point.the division stops, there is n® line visible below that point, by which the separation could be conti- nued. 'The dens fissus is often perforated in such a man- ner, as to prove, that, in many instances, the division is the result of a series of lacunee. A dens fissus should be con- sidered as unity; a dens geminatus as a compound. ‘The latter might be called dens separabilis, or dens fissilis; the former simply dens fissus. The denies per paria approximati are at no period of their growth longitudinally united; they are understood to be always separate, although not equidistant. ‘Thus they must not be confounded with the dens geminatus, which is often divided to the very base by the linea separabilis. To illustrate this a little farther, we will take a peri- stome of a Splachnum for examination; and suppose (as often takes place) that two or four of the thirty-two pri- mary teeth are united by longitudinal cohesion. These teeth we would term wni- or bi-geminantes ; and the tooth formed by this gemination, wni- or bi-geminatus. In seve- ral genera, as S'plachnum, Orthotrichum, &c. this structure of the teeth forms a leading character *. * We are aware, that, in the present state of muscology, we are liable to censure for the introduction of new terms and definitions, and the more so, that it is extremely difficult to define our ideas in express words. Thus several mosses are represented as having a longitudinal line down the middle of their teeth, and yet we have several reasons for doubting if they be really geminated ; though a geminated tooth may be only partially divided, and is marked by a line, still we do not intend to assert, in every case where such a line is figured, that the tooth is geminated. It is therefore to be much wished that such as make drawings of the peristomes of mosses, would pay parti- cular. attention to this point: THE GENERA OF MOSSES. AAG When the dens fissus is cleft to the base, or nearly so, it becomes difficult to distinguish it from two teeth per paria approximati ; and it is not improbable that the latter are, m some instances, nothing more than dentes fissi ; but little or no confusion can arise from using two names to denote different states of the same structure. Weser and Mour (Handbuch, p. 10.) have some ob- servations under Splachnum, much to our purpose. “* Hu- jus et Orthotrichorum quorundam dentes non tam per paria approximati, sed principio adglutinati observantur. Posthac, imprimis si dentes reflectantur, nexus inter gemi- nos tollitur, et tum primum 16 distinctos reperis.

Quare Splachnorum et horum Orthotrichorwm dentes 8 geminati,, Didymodontiwm per paria approximati dicuntur.” We have now, finally, to remark, that, in our opinion, it will always be found, when a gemination of the teeth ac- tually takes place, that the peristome, in the young state,. forms.ene uniform undivided, but longitudinally striated, submembranous substance *, which is usually arched over the orifice of the theea; the tendency to split into a definite number of teeth being afterwards developed and regulated by the laws of nature. This idea appears to be corroborated by the fact, that, in the same tuft of specimens, we have re- peatedly observed peristomes with six, eight, or twelve teeth, * This structure, which we attribute both to the Splachnoidee and Ortho- trichoidee, will certainly exclude from these orders any of the other species to which some have attributed a geminating line down the teeth. 448 NEW ARRANGEMENT OF and this in several species of Splachnum; the longitudinal lines, however, invariably denoting the total number of teeth to be thirty-two.

In the Orthotrichoidee, the calyptra is permanently mitriform, loose about the theca, generally furrowed, and pilose; or, if glabrous, it is either laciniated at the base, or with four or five large triangular appendages.

Oss. We have already stated, in our observations om the present group, how nearly related are all the genera contained: in it. Nevertheless there are no mosses (the Orthotrichoidese alone excepted) which vary so much in the: apparent configuration of the peristome, or rather, in the: combinations of its primary parts, when in the dry state. When moist, on the contrary, there are no mosses, the pe- -ristomes of which so remarkably resemble each other. In. this state, all the teeth are united, as it were, into one mass,. usually arched over the orifice of the theca, and divided, longitudinally by.a definite number of equidistant striae, by means of which,. it 1s easy, m almost every instance, to, THE GENERA OF MOSSES. 4AdSL calculate that the total number of teeth is thirty-two: but it is very difficult, if not impossible, to say where the separations are to commence, or how many are actually to take place. This is remarkably illustrated in S. spheri- cum, in which the line down each geminated tooth, or the linea separabilis, appears as strong as that by which actual separation is produced. ‘This structure sufficiently accounts for the different combinations observable in the teeth of the peristome, not only in the different species, but even in the same species. As few, or indeed any, plates exist which give a correct representation of the peristomes of the Splachna, and as most descriptions are equally erroneous (or at least only partially correct), we subjoin the result of our own extended observations. 1. S. ampullaceum. In this species the teeth are, in some specimens, 16 unigeminated, and geminating in pairs: in others (and more usually) 8, equidistant, bigeminated. | 2. 8. vasculosum presents the same variation. Hrepwic’s figure of both species is incorrect. That of the pre- sent one, extremely so, except in the leaves. 3. S. sphericum. This varies more than any other in the combinations of the teeth. There are in gene- ral 8, equidistant, either entire or slit down to the middle, and each of the divisions marked with a semipellucid line. Sometimes there are only 4, equi- distant, each made up of 8 parts. In other speci- mens, again, there are 16 teeth, in the dry state, geminating in pairs, each with a longitudinal semi- pellucid line. A: S. Wormskioldi.

The FfQ2 452, NEW ARRANGEMENT OF original figure of this plant, in “ Flora Danica,” re- presents them as placed in pairs. 5. S. tenue. In very recent specimens there appear to be 8 equidistant, bigeminated teeth; but the pro- cess of drying (without pressure) produces a divi- sion into 16, geminating in pairs, each with a lon- gitudinal line, denoting simple gemination; this line is somewhat obscure,. from the thick substance, and consequent greater opacity, of the teeth. ‘The i figures in Weper and Mour, Tasch, t. 7. f. 2., and in “ English.

Our own specimens have lost. their peristomes; but. from Brown (in the Appendix to Parry’s first Voyage, p. ccc) placing it in the genus Splach- num, ‘* dentibus reflexilibus,” we are inclined to do- the same, as that gentleman, the discoverer of the species, must have had more numerous opportuni- ties of examination than any other.

In native specimens of this species we have had no difficulty in observing ‘either 8 equi- distant bigeminate teeth, or 16 unigeminate ones, geminating in pairs. In specimens which we regard as belonging to this species, brought from the Arc- tic regions by Captain Parry, the teeth are ex- tremely pellucid, and the line down each of the 16 teeth either very faint or invisible. None of the published figures of the peristomes are correct. 9. S. urceolatum. Hevwtice, and also Sturm in“ Deutsch- ands Flora,” figure a-peristome of 8 once geminated teeth. In “ Flora Danica,” t. 1361, there are re- presented 16 single equidistant teeth. We have found 8 equidistant, marked with 3 lines, at none of which have we observed any ultimate separation. 10: S. angustatum. Brown, in Parry’s Voyage (Ap- pendix), has observed the peristome to consist of 4 bigeminate teeth. We have also seen it of 4 teeth, but m our specimens they are satisfactorily quadri- geminate.

Peristome in every respect similar to the preceding. From the above detail of facts and remarks, it appears, 454 NEW ARRANGEMENT OF lst, That every Splachnum, according to our view of the genus, has $2 primary teeth, placed in twos, in fours, or in eights, (or even sometimes irregularly ).’ In this place we must notice the four additional species constituted by Brown, in the Appendix to Parry’s first Voyage, to all of which that profound botanist attributes 16 teeth for the primary number. We cannot confirm this, as we do -not possess authenticated specimens of any of them; but con- ceive so remarkable an exception should be very cautiously admitted into physiological reasoning. That 16 teeth, how- ever, were only visible in the peristomes examined by Mr Browy, is a fact not to be questioned on his authority. 2Qdly, With the exception of S. Wormskioldit, whenever the teeth present the appearance of bemg 16 once gemi- nated, they are also placed in pairs, though not equally so in every species, for we have observed them almost equi~ distant in specimens of S. sphericum; and Mr Brown also mentions, that, in S. longicollum of Dickson (a plant of North America), the teeth are ‘‘ vix manifeste per paria approximati.” In §. Wormskioldtt these teeth are equi- distant, the main character, we apprehend, on which Mr Brown has founded his genus Aplodon. It should be recollected, however, that the 16 teeth of S. Wormskioldit are each composed of two united ones; or, in other words, they are gemimate. We candidly con- fess, that those species which have 8 equidistant teeth, ap- pear to us equally deserving of generic distinction, seeing that they are equidistant, though fewer in number, and composed of the same primary parts, each tooth being bi- geminate. Taking, therefore, into consideration the great variety of combinations of these teeth, and the laws which the combinations seem to follow*, we have relinquished all * The teeth are found to unite either in twos, in fours, or in eights. In S, Wormskioldiz they are in twos. THE GENERA OF MOSSES. 459 hope of forming genera of the Splachnoidee on characters thus derived. From the remarks we have brought.forward, it will be xeadily perceived that we can scarcely coincide with Mr Brown in his views regarding S. Wormskioldii. At first sight it bears a strong resemblance to S. sphwricum, so strong, indeed, that the indifferent, though original and authentic, specimens we received of the “ Flora Danica” plant, we were at first tempted to consider as.a mere va- riety of that species. ‘Those brought home by Captain Parry proved them to be sufficiently distinct, the principal difference, however, seeming still to reside in the peristome. The fruit-stalk of SS. Wormskioldit is certainly remarkably vasculose and succulent ; but we have a very near approxi- mation to the same structure in S. sphwricum, especially in that variety of it which has been called gracile. It is also seen in a somewhat less degree in S. vasculosum. In regard to the peristome, we have already shown that, in the moist state, there is no difference in the peristomes of any of the plants we have here brought together. When dry, it is true, the 16 geminated teeth of S. Wormskioldi are equidistant, though the other Splachna have them piaced in pairs. Yet on this character Mr Brown has ob- served, “ Transitus ab Aplodonte ad S'plachnum facilis est per S. longicollum, cui dentes vix manifeste per paria ap- preximati, qua nota differt a §. tenue valde affine sed dentibus geminatis reflexilibus instructo.”. When such in- termediate gradations exist, we submit, with the utmost deference, whether it be not desirable to keep together plants so intimately united by structure as well as habit. There is one point of difference between 8. Wormskioldiz and other Splachna, which we have omitted to notice. The columella is nearly simple, or not nearly so capitate as in the rest. This, however, 1s a subordinate distinction, and 456 NEW ARRANGEMENT OF of less importance, when we consider that there is almost: every gradation from the broad and tabular termination of this part in S. rubrum and lutewm, to the simpler one in SS. Wormskioldii. We have, however, even in this last, seen it dilated at the apex ; but they were rare instances. In our character of the genus we have described the theca as subcylindrical. This is true in a general point of view, but in particular instances liable to variation. Thus, in S. tenue, it is occasionally oblong, or even subglcbose : in S. Wormskioldit often contracted both at its orifice and base, and in the arctic North American specimens so as to be almost globose. The apophysis assumes various ap- pearances, though nearly constant in each individual spe- cies. Its colour is almost always green in the young state, and as constantly changes in maturity. In 8. vasculosum its surface is singularly rugose or undulated, a character altogether omitted in Hepwic’s figure (St. Crypt.), and even not sufficiently indicated in HooxEr’s supericr repre- sentation (in Musc. Brit.) This remarkable feature we have observed in another plant we have found on Ben Lawers, of which the plate of S. rugoswm, im “ English Botany” (t. 2094.), is so faithful and characteristic, that we have no doubt whatever in referring it to that species. In most species the apophysis is of a sufficiently rigid nature to retain its form to the last. SS. rubrum and luteum, however, are possessed of one so large, and, at the same time, of so delicate and membranaceous a structure, that it speedily becomes collapsed, and the base of the apophysis is brought into contact with the base of the capsule. The sporular sac in the Splachna (and probably in all other genera, as already mentioned under Diphysciwm) is, in the young state, supported by a pillar formed, as it were, by an internal continuation of the fruit-stalk. This must, in Splachna, pass, of course, through the apophysis, and is THE GENERA OF MOSSES. AST correctly enough represented by Hepwie in his figure of S. ampullaceum (St. Crypt. v. 2. f. 14.) The calyptra in all our British species is whitish: in S. Wormskioldit of a brownish hue. As far as we have seen, it is truly mitriform in its young state, and becomes dimidiate only by the enlargement of the capsule, when it is almost immediately deciduous. Our excellent corre- spondent, Professor Hornscuucn, is of the same opinion,’ and even observes, “‘ mehrere Splachna haben eine calyptra campanulata multifissa die en die C. dimidiata ubergeht*.” Haz. The Splachna are widely distributed throughout the alpine and the northern parts of Europe and North America. Species have been found also in the Straits of Magellan and in New Holland. Their places of growth are most remarkable, the greater number being found upon the dung of various animals. We ourselves have gathered SS. mnioides attached to the long exposed bones of an ox. A friend of ours, who received the skull of a musk-ox, brought by Captain Parry from Melville Island, disco- vered a luxuriant specimen of the same species (if we mis- take not), lodged in the bones of the nose. Our esteemed friend Dr Ricuarpson mentions that he always found it in arctic America, enveloping with its roots the bones of some small animalt. But though most prefer some animal substance or other, there are exceptions; a few growing on the ground or in wet springy places, and one alone (S. octo- blepharum) on the rotten trunks of trees. _Hist.

DitiEnius {, however, throws some light on this question, when he traces the plant of Dioscoripes to belong to the genus Usnea. Nevertheless, with all the want of connexion between it and the true mosses, we find that Laur. Monti, in the second volume of the “‘ Ameenitates Academicz,” p. 248, bestowed the name upon the present genus, with the following character : ** Calyx calyptrata, operculata, receptaculo membranaceo, colorato, maximo, imposita.” After which we have these remarks: ‘ Genericis itaque characteribus propositis, no- men antiquum, Splachnum, hine adjungam, mutatum a DioscoripE, qui Muscis hoc imposuit.

A fourth, S. rubrum, from Lapland, is inserted in the Appendix. © Mont!y, in the essay we have quoted, unites the three first, and adds S. Juwtewm under the name of flavum. Since, then, other species have been described from time to time. Hepwice, in his “ Stirpes Cryptogame,” has three species, not known to Linnezus, 8S.

Scuwaz- GRICHEN, 1n his first Supplement, enumerates in the whole fifteen species; of which, however, we regard S, gracile and S$. ovatum as varieties of S. spharicum, and S. Breweri- anum as a variety of S. mnioides. In his second Supple- ment, he has described S. melanocaulon, which is, in our opinion, merely a dwarf variety of S. luteum. Sir J. E. Suir has still another species, in “ English Botany,” S. rugosum of Dickson. We are ignorant whether this be really Dicxson’s plant or not. The authors of “ Musco- logia Britannica” state, that, from an examination of Dicx- SON’S Own specimens, they refer it to S. sphwricum. Be all this as it may, we have assuredly found the plant so well represented in “ English Botany,” and consider it specifi- cally distinct from S. vasculosum, to which it is nearly allied. Dicxsen, who is the original authority for many species taken up by Hepwic and Smitu, has described another species, about which much doubt has arisen: this is S. longicollum, a plant which has been referred by Doc- tors Hooxer and Taytor to S. tenue. Brown, on the other hand, says that it has never been found in this coun- try, ‘* Americee occidentali nec Scotize indigenum *,” and that it is different from S. tenwe. We have now a few recent works to notice. Out of the seven species contained in the ‘* Muscologia Britannica,” we have referred S'. Frelichianum to the next genus (Dis- _sodon nobis). In Hooxer’s “ Musci Exotici” are two spe- cies, S. octoblepharum and S. scabrisetum, the latter of which we also refer to Dissodon. NHornscuucu, in the * Parry's first Voyage, Append. p. ccxcix 460 NEW ARRANGEMENT OF “© Hore Physicz Berolenses,” has figured the beautiful S. Adamsonianum, of which we have no authentic specimens. A plant has been recently communicated to us by Dr Hooxrr, brought home by Captain Parry in his second Expedition, and which is no way different from the Kamt- schatka one: Dr Hooxer at the same time mentioned that he considered this identical with the S. paradoxum of Brown. It appears a good species, intermediate between S. tenue and mnioides. We can scarcely presume to judge of S. arcticum, propinquum, and exsertum, of Brown, in the Appendix to Parry’s first Voyage, as we have not specimens; but we cannot resist the suggestion that they may be different states of that polymorphous species S. mnioides,—nor do we even venture thus far, without having examined very many varieties of what we consider .S. mni- oides, presented to us by Mr Epwarps, and other gentle- men who accompanied Captain Parry on his second voy- age. : After subtracting from the twenty-two species, described by BeiveEt, those which are mere varieties, and some spe- cies belonging to other genera, and adding to the remainder, S'. octoblepharum (Hoox.), S. Wormskiolditi (Hornem.), S.longicollum(Dicxs.), and. §. Adamsonianum (Hornscz#.), we shall count sixteen well-established species °. * Of those we reject, S. Wulfenianum is Orthotrichum Ludwigii (ScuwacK.)—S. Frelichianum we place under Dissodon (excluding, of course, Gymnostomum Griffithianum, confounded with it by Barpex and Swarrz).— S. lingulatum is our Dissodon splachnotdes.—S. serratum and flagellare are varieties of S. tenue.—S. Brewerianum, a variety of S. mniotdes.—S. seta- ceum, certainly only a variety of S. angustatum.—S. ovatum and gracile, varieties of S. sphericum.—S. pusillum, according to Patuisot’s Herbarium, is S. vasculosum.—S. Turnerianum does not differ from S. ampullaceum.— As to S. Juress?, we have not seen it, and know not what to make of it. i ‘ fA PLATE XH Werr. Mem.

There is no appearance of serratures, and the nerve in every instance disappears a little below the summit. The perichetial leaves do not differ from the rest, except in being perhaps more patent. Oss. For the institution of this genus, as well as. the alterations of the preceding one, we solicit the indulgence of muscologists,—at least till what we have advanced has been submitted to a fair examination. It may be urged against us that we rest too strongly upon the appearance of the peristome ina dry state. We do believe that, in this genus, the main generic distinctions are to be taken from the characters then exhibited. We have shown that, when moist, nearly all the peristomes of the Splachnoidee have AO4 NEW ARRANGEMENT OF a wonderful resemblance to each other; that, in short, ne generic marks can then be collected from them. When, on the other hand, we note the direction of the teeth in a dry state, and find that they constitute more ob- vious distinctive features ;—that all those species which have reflexed teeth form a natural group, even to the acute form of the leaves (except in §. vasculoswum alone);—that all those which have erect teeth * (not reflexed) agree still more beautifully in habit, their capsule of a different shape, their apophysis narrower than the capsule, and of the same colour, their leaves all agreeing most strikingly in their ob- tuse form and texture ;—that, farther, when we see equally forcible characters taken from the direction of the teeth in the dry state of Tayloria, we cannot help flattering our- selves, that, for the tribe of mosses now under considera- tion, these are the only tangible generic characters. ‘Those we have discarded seem only of importance, inasmuch as they indicate affinity and similarity of structure. | The peristome of Dissodon varies much in the same manner as that of Splachnum : 1st, In one species, the teeth are 16, once geminated, and equidistant; besides which, each tooth, when mature, is divided at the line of gemina- tion, either to the middle or to the base. 2dly, In another species, the teeth, though 16, and also equidistant, remain permanently once geminated. $dly, In the other species, they are 16 once geminated, and also geminating in pairs*+. * Mr Brown seems to consider erect teeth as worthy to constitute a subgeneric character, and thinks §S. Fralichianum and S. Wulfenianum might be placed together on that account, joined to the inclined capsule Parry’s First Voy. App. p. ccci- -+ We have in our possession, through the kindness of our friend Dr Hooker, a plant which we consider to belong to this genus: but as it has only a manuscript name attached to it, we refrain from noticing it farther. It assimilates with the rest in every character. bea THE GENERA OF MOSSES. 465 OF the first mentioned of these we have the genus Systy- hum of Hornscuucu, on account of the teeth being rather short, erect, geminating in pairs, and the lid connate with the columella. Of the second, we have the genus Cyrtodon of Brown, on account of the teeth being long and incurved at the apex. Of one of the last, Mr Brown observes, *¢ Splachnum Frelichianum et forsan S. Wulfenianum *, capsula inclinata et dentibus erectis a Splachnis genuinis distinguitur, et subgenus efformat.” Under Aplodon, the same author shows, nevertheless, how near his Cyrtodon is allied to S. Frelichianum: ‘‘ Diversa preesertim dentibus erectis apicibus incurvis, ideoque S. L’ralichiano dentibus erectis, sed geminatis affinis.”. Upon these principles, we fear, genera might be constituted of several more species of Splachnum ; for instance, Dissodon scabrisetum (Siplach- num scabrisetum, Hoox.) has the teeth involute in a re- markable degree, when moist --, and in this circumstance differing from all the rest ; this is, we apprehend, as valid a generic character as some of the above,—but, at the same time, of as little consequence. Of all the plants we have brought together under this genus, Systyliwm seems, at first sight, to have the greatest claims to be kept apart, and that, on account of the long persistent lid. We agree with Brown, however, that this ean scarcely form a generic character. Under Aplodon, he observes, “ In hoc enim cohzrentia operculi cum columella ex analogia cum Gymnostomis quibusdam, pro charactere specifici tantum valoris habenda sit.” Besides, the lid even- tually separates from the columella: but a stronger reason * This plant is Orthotrichum Ludwigii. + We do not mean to say that the teeth were involute before the oper- eulum dropt off, but only after having been exposed to the action of the at~ mosphere. VOL. V. & 466 — NEW ARRANGEMENT OF still against its being retained as a generic character, is, that a similar circumstance exists, in a less'degree, in recent specimens of Dissodon Splachnoides (Weissia Splachnoides, Auct.) The lid is here very frequently adnate with the columella for a considerable time, and is so represented both by Dr Hooxer in “ FI. Lond.” and Dr GrevitLE mn “¢ Crypt. Fl.:” it is therefore at least exactly intermediate, in this respect, between Hornscuucn’s Systilium and the rest of our Dissodontes. Two very remarkable points, common to all our species, are, the ovate form of the theca, and the obconical apophy- sis: the latter tapering downwards from the base of the eapsule, renders the shape of the whole more or less ob- ovate, and affords a fructification very different, at first sight, from that of Splachnuwm; more especially when we take into consideration the equally remarkable fact, that, in Splachnum, the apophysis is coloured, whereas, in Dis- sodon, it is of the same colour as the capsule. ‘Thus, not only in habit, but m every character of importance, do all the species of the latter genus agree. Has. We are not aware that any of the species are pro- duced on any decomposing substances, as are most of the last genus. One is found among rocks; another in a firm, wet sward, intermixed with grass and cther plants; a third in the crevices of rocks. As to the fourth, we do not cer- tainly -know on what it was found growing. ‘Three are pe- culiar to the alpine parts of Europe. ‘The other occurs in South America. Hist. We have already mentioned that one of our spe- cies had previously constituted a genus under the name of Systylium, and that of another was formed Cyrtodon. As these names imply a peculiarity of structure not common THE GENERA OF MOSSES. 467 to all the plants we have brought together, we have been obliged to reject both, although, from respect to Mr Brown, and friendship for our correspondent Dr Hornscnucn, we would gladly have avoided it, if possible: Had not the name Orthodon been preoccupied, it would have been pre- cisely that we should have taken for the present genus; which we have denominated Dissodon, a word at least ex- pressing a character common to all the species. The first known of our species was described and figured by Hep- wic, and about the same time discovered in this country by Dickson on the Scottish alps. Dickson seems to have dis- covered the next, and published it as a Splachnum; but Swartz, almost immediately following, described it as a Weissia, the generic name of which it has retained ever since, till Brown gave it that of Cyrtodon. Of this plant, we may here remark, that, from the imperfection of the specimens existing in herbaria, no correct figure had been given till the year 1824, when both Dr Heoxer and Dr Grevitte published ample analyses of the different parts. The geminated structure of each tooth was observed some years ago by Mr Arnort, in specimens procured from the Reverend Mr Macrircute of Clunie, and urged with se- veral muscologists as a proof how incorrectly it had been allowed to remain in the genus Weissia. Mr Brown, how- ever, has the first claim for the publication of this structure. To Dr Hornscuucn we freely expressed our opinion that his Systyliwm could not be separated as a genus from the same plant. Along with additional specimens for examina- tion, he obliged us, in return, with the following remarks : —* Ich night glaube dass es mit Weissia Splachnoides in ein genus vereinigt werden kann, da der Bau der Taehne gar zu bedeutentend abweicht, wie Ihnen die Untersuchung zeigen wird, auch ist die Verwachsung des operculi mit der Columella so standhaft und ausgezeichnet dass sie nach Gg2 468 NEW ARRANGEMENT OF meinen dafirhalten immer als Merkmaal bey Aufstellung des Gattungscharackters mit zu Hiilfegenommen werden kann.” We have examined the specimens he kindly sent to us, and regret to say we still cannot coincide with him on the importance of the characters which he draws from the peristome and columella, above alluded to. As we have united several genera in the formation of Dissodon, - we conceive that characters of the species may not be un- acceptable. 1.

No plant that has come under our observation has so great a resemblance to this species as Splachnum tenue : the likeness is indeed so strong, that, to the naked eye, there is no difference, except in the lid, which, if it be wanting, leaves the microscope alone to determine between the two. With the assistance of that instrument there is no difficulty, if the peristome be present. Dr Hooxer has figured this moss more correctly than any one else, and represented the approximation, or rather -gemination, of the teeth with more truth than Scuwaeri- CHEN. They are of a very fine red, most remarkably long, longer even than the theca itself; in the dry state they be- come reflexed, and tortuous in an extraordinary degree, contracting and expanding themselves with great rapidity on the application of the slightest degree of moisture or warmth. The fruit-stalk varies from one to two inches in length, and is smooth, solitary, erect, or slightly flexuose.

THE GENERA OF MOSSES. 473 Hisr. Under this head we have little to say, there be- ing only one species in the genus, and that one recently introduced to the notice of muscologists. We believe it to have been discovered by the lamented Professor Scumipt of Christiana, the same who accompanied Captain Tuckry in his expedition to the Congo river. We know not if he bestowed on ita name. In 1814, Dr Hooker found it on the Grimsel, close to the Glacier du Rhone, at an altitude of about 5000 feet ; and he soon after constituted the pre- sent genus, in order to receive it, in Branpe’s Journal of Science and the Arts*. In the mean time, ScHLEICHER and SERINGE also gathered it in Switzerland, and transmit- ted specimens to SchwaericHEN, under the manuscript name of Hookeria. Thus while Hooxer dedicated it to his friend, and future coadjutor in the Muscologia Britan- nica, it was named on the Continent after himself ;—a sin- gular and interesting coincidence. It so happened that both names were made public in the same year (1816). Tayloria, however, had the precedence of some months; yet it is a strange circumstance that, till recently, it has been discarded by every continental botanist, and Hookeria substituted in its place, although that name was preoccu- pied by Sir J. E. Smiru, in favour of another genus, also . of mosses. We rejoice to find at length the justice of the claim of T'ayloria acknowledged. Our friends NeEs von Esexsecx and Hornscuucn have taken up both it and Hookeria of Smiru in their excellent ‘“ Bryologia Germa- nica;” and we are acquainted with no muscologists pos- sessed of more liberal feelings, or who are so well able to establish both genera as firmly on the Continent, as they have long been in this country. SprENGEL has also adopted * No. 3. p. 146. AT 4 NEW ARRANGEMENT OF MOSSES. Hookeria*. It must be confessed, that, when our friend Professor Scuw#cRICHEN thus expressed his opinion cen- cerning Smiru’s Hookeria, “ Quam proposuit SMirHius in Actis Societatis Linneanze, v. 9. p. 272, Hookeria in systemate Fedwigiano genus proprium esse nequit,” he should at least have left the field open, and the name other- wise unappropriated ;—Sir J. E. Smiru being besides a warm supporter, and no less an able one of the Hedwigian school. PLATE XIII. Fig. 51. Capsule of T'ayloria, with the operculum. 52.

XXVII.— Notice in regard to the Trap Rocks in the Mountain Districis of the West and North-west of the Counties of York, Durham, Westmoreland, Cumberland, and Northumber- land. By Henry Wiruam, Esq. of Lartington. (Head 3d May 1824.) Tue various opinions which have been entertained. at different periods respecting the origin of the Trap Forma- tion, by the most distinguished geologists, gives a pecu- liar interest to its geognostical history, and confers on those districts where it occurs a high degree of importance. Some geologists, as is well known, maintain, that secondary trap rocks owe their origin to the action of subterranean heat ; which power, it is alleged, was instrumental in giving them their mineralogical characters, and present position in the crust of the Earth. This immeasurable power, according to the igneous theory, forced them from their birthplace, very deep in the bowels of the earth—even under gneiss and mica-slate, through every variety of primitive and transition rock, to their present place in the formations of the second- ary class. These secondary traps, then, if this explanation 476 ON THE TRAP-ROCKS IN YORKSHIRE, &e. — is the true one, are placed deeper in the crust of the Earth than gneiss and other primitive rocks. But this Huttonian explanation is opposed, and with much mgenuity and force of argument, and detail of fact, by the Neptunians, who Insist on the deposition of trap from aqueous solution and suspension. We do not pretend to advocate either opinion, but maintain, that these rival hypotheses have been eminently useful, and that, without their aid, geology would have long remained stationary. Can we believe those to be in earnest who assert, that opinions, which have been the means of calling into action the zeal and acuteness of such observers as Hatt, Jameson, and BuckLanpb, and which have afforded opportunities for splendid displays of the powers of Hutron, Werner, Piayrair, and CuviEr, have been not only useless, but even pernicious ? On visiting the districts enumerated above, my attention was forcibly arrested by the phenomena exhibited by the trap-rocks, and it is of these I now propose to lay a notice before the Society. But as these are considered by geologists as forming part of the same general series with those of Derbyshire, we shall first mention shortly the Derbyshire stratification. In the metalliferous strata of Derbyshire, it appears there are nine different alternations ; namely, grit-rock 120 yards, limestone-shale 160 yards, first limestone-rock 50 yards, first toadstone or amygdaloid 20 yards, second limestone-rock 50 yards, second toadstone or amygdaloid 30 yards, fourth lime- stone-rock 130 yards; making a total thickness of 650 yards. Here we perceive the beds of metalliferous limestone are se- parated by beds of trap rocks, called Toadstone. When a vein of lead is worked through the first limestone down to the toadstone, it ceases to contain ore, and often entirely disappears. On sinking through the toadstone to the second limestone, the ore is again found, but cut off by a lower ON THE TRAP-ROCKS IN YORKSHIRE, &c. 477 bed of toadstone, under which it again appears in the third limestone. In a few instances strings and short branches of ore have been discovered, but the few veins which pass through this substance contain no ore. How to account for this unequalled stratified arrangement must require no small share of ingenuity. It has been maintained, that the toadstone and limestone, with the metallic veins of this district, are of contemporaneous formation, but the differ- ent organic remains in the upper and lower beds of lime- stone preclude the possibility of such simultaneous forma- tion. Cuvier has very justly observed, that the existence of different organic remains, offers irresistible proof, that the upper and lower stratain which they were found, were formed in succession. ‘The rapid progress of the science of chemistry, will, it is to be hoped, ere long, dispel the darkness, and furnish a solution to this hitherto unex- plained phenomenon. - The great trap mass of 'Teesdale shews itself on the south bank of that river, just opposite to Middleton, in Tees- dale, and extends to a great breadth to the Chain-bridge, where it forms the bed of the river, which has worn a deep chasm through it.. At the Highforce (a waterfall of 70 feet perpendicular) the river has worn its bed com- pletely through it, and shews it resting on the encrinite lumestone, and dipping regularly to the NE. at an angle of not more than 12° with the horizon. Here may be dis- tinctly seen, on the nght side of the waterfall, the great Marbeck vein, intersecting both the trap and the lime- stone. This fact is interesting, as to the relative age of this trap, shewing it must have been in existence previous to the formation of the veins which pass uninterruptedly from the other strata through it. I am informed by miners this is always the case, and that they very frequently bear ore. At Maisebeck, in Tyne Bottom, there is a rib of 478 ON THE TRAP-ROCKS IN YORKSHIRE, &e. solid ore of four inches, which intersects the trap. The specimens I have now the honour of laying before the Society, are from a vein which runs east and west in the basalt, which extends over this district immediately at the foot of Crossfell, and is at present working at the pomt where Troutbeck, coming from the south-west, joims the river Tees. ‘The vein from which I obtamed: these speci- mens is supposed to be a prolongation of one at present working in Harwood. If this could be ascertained, I think it might lead to some very interesting speculations on the subject. My friend Mr Josiine of Newtonhall, to whose kindness I am indebted for much useful infor- mation, 1s not aware there are at present any veins. raising ore in this district, but there are many old workings in the basalt. The trap rises to a considerable elevation, and in prodi- - gious masses, from the Highforce to the south of Croakley and Croakley Fell, and at Cauldron Snout, about six miles NW. from the Highforce, where it again interrupts the pro- gress of the Tees, and gives rise to a succession of beautiful cascades, to the height of 200 feet. Here it rests on the same limestone, and is covered to the NE. by a white and highly crystalline quartz-rock, which is intersected im every direc- tion by bearing lead-veims, which the miners say penetrate the trap, but, owing to the hardness of the substance, has not been profitable to work. The colour of the trap (of which you have here a specimen) is bluish-grey, a mixture of augite and white felspar in small crystals. It is extreme- ly hard and tough, and the fracture inclined to conchoidal. It sometimes inclines to the columnar form, particularly at the Highforce, and other interesting sections in the neighbour- hood, ‘The dip of the trap corresponds with that ‘of the other strata NE. The most intelligent miners are of opi- nion that this rock may be traced for above thirty miles to ON THE TRAP-ROCKS IN YORKSHIRE, &e. 479 the south of the above described boundaries. ‘They con- sider it as perfectly stratified, and estimate its depth from 12 to 18 fathoms. The extent of this field of trap is of prodigious magnitude. Its length from N. to S. must exceed 70 miles, and in many situations its breadth is from 12 to £5 miles. From what source this great trap-range is to be traced, isa subject upon which the most highly enlightened geolo- gists, mineralogists, and chemists, are as yet at variance. By some it is believed that this immense mass of greenstone has been poured out from that singularly extensive and curious whin-dike (commonly called the Bolam, or York- shire Dike), which may be seen marked in all the geologi- eal maps. It may be distinctly traced from the German Ocean, near Whitby, a distance of above 70 miles, into the field under consideration. By cthers, it is contended, that it is the production of a vast volcanic eruption from the al- pine chain atitshead. To others, again, there appear strong reasons to suspect either of these possibilities: ist, The source from which it is supposed to flow, is not known to contain any metallic ores; 2diy, 'The substance in this great extent appears to have no tendency to vesicular concre- tions, or any vitreous appearance; and, 3di/y, Its regular stratification for so great a distance, induces belief, that its formation has been in contemporanecus succession with the various strata forming the successive and curious alterna- tions in this interesting district of the lead-measures. The vast extent of this mass of trap or greenstone, its stratification, its ves of galena, its relations with the neighbouring strata, render it highly deserving of the at- tention of the geologist and the miner. The present notice, although very imperfect, will, I trust, lead to a farther examination of the trap-rocks of 480 ON THE TRAP-ROCKS IN YORKSHIRE, We. the north of England, and also to a comparison of the phenomena of their various junctions, alternations, and intermixtures with those exhibited in other parts of Eng- land and particularly in Scotland, a country eminently dis- tinguished for the varied and highly interesting displays of the formations of the trap-rocks.

This interesting Moss unquestionably belongs to the ge- nus Anomodon of Drs Hooxer and Taytor. Not feeling, however, perfectly convinced of the expediency of that ge- nus, I have preferred, for the present, placing this new species in the genus Neckera, at the expence of which Anomodon itself was constituted. -Neckera Americana 1s very nearly related to N. viticuwlosa (Anomodon viticulosum, Muse. Brit.), and has the same peculiar habit, and mode of growth, leaves of the same dense and fragile texture, and a fruitstalk and capsule nearly similar. In size, however, it is much smaller, the leaves are little more than half the length, rounded at the extremity, and the nerve disappears at a considerable distance from the summit. The capsule is also shorter. The great resemblance between these two mosses cannot escape the most careless muscological observer, and may suggest to many the existence, though in an inferior degree, of the same relation between some of the Cryptogamous plants of Europe and North America that has been detected between numerous Phzenogamous plants. It would be hazardous, in the present state of muscology, to dilate on this subject, any more than on the general geographical re- lations of mosses ; especially as from what we do know, we find. the observation to be correct, that the lower we de- scend i in the scale of vegetation, the less the distribution of plants : over the surface of the globe seems to be regulated by the laws that influence the more perfect vegetable forms. Nevertheless, we do not find in the mosses a disposition to a matked geographical distribution altogether abandoned. The curious genera Phascum Voitia and Tetraphis seem to be confined to temperate and cold regions, and are OF THE-GENERA NECKERA AND HYPNUM. 483 ‘mostly limited to Northern’ Europe. On the other hand, Calymperes-vequires.a considerable temperature ; ; and the genus, Hookeria containing, ‘according. to Dr Hooker and myself thirty species, » ‘besides doubtful ones, 1s, with the exception of two. species, wholly extra-european. — It is alse “worthy of notice, that, in the extensive genus Orthotrichum, _of which we have published fifty-nine species, all those not found in Europe and North America, possess a peculiarity of habit at once recognisable, and for the most part also a difference in structure. That singular group, too, of mosses, denominated Leptostomum by Mr Brown, has hi- therto been only found in New Holland, Van Dieman’s Land, New Zealand, and at Cape Horn. From these few facts alone, selected from various others that might have been brought forward, we have some reason for Cone ing that, at a future period, the distribution of the mosses will be found to be a more interesting subject than we at present anticipate; and that, even in those large genera, ‘which now appear to scatter species indiscriminately over every country of the globe, sectional groups will be found, affecting perhaps different temperatures and latitudes from the rest.

I can assure those gentlemen who have occasion to send packages of minerals and other things from differ- ent parts of the world, that, by using mosses, lichens, ¢c. as materials for packing, they may greatly enrich the col- lection of the muscologist, and forward the progress of this department of natural history. EpINsuRGH, May 5. 1825. - ( 485) XXIX.— Account of the Method of Drawing Crystals in True Perspective, followed in the Treatise on Mineralogy of Professor Mous. Pe W. Harpincer, Esq. of Vienna, F.R.S.E. Member of the Wernerian Society, &c. (Read 14th May 1825.) ALL those who have devoted their atterition to the study of Crystallography, must have experienced many difficulties arising from the want of a proper method of drawing the projections of crystals, an object which, at the same time, should be effected with perfect ease, and with sufficient accuracy. ‘Those who already possess the required crys- tallographic knowledge, will, mdeed, very soon be capable to draw up rules for themselves; but this knowledge is not yet so generally diffused as it deserves, both for the influ- ence it is likely to take in the progress of the science, and for the wonderful regularity of nature which it displays. The very attempt of drawing crystalline forms is insepar- able from a close examination of these, and therefore a step forwards in studying crystallography ; we may acquiesce m giving a vague verbal description of a crystal, but a vague representation of its figure seems ta imply some 1m- 486 ON DRAWING CRYSTALS possibility for any person who is accustomed to accurate investigations. It is.to.a. great extent the use of correct figures which has given Haiiy’s crystallographic method that great superiority which it has always enjoyed over the Wernerian method, bothin accuracy. and elegance; and to the study of Haiiy’s plates, far more than to the study of his writings, we must look as the point from which the sub- sequent labours of crystallographers started. . By far the greater number of the figures in the first edi- tion of Haiiy’s J'raité are executed with care, and according to the best method which could possibly have been adopted. Since the appearance of that work, most of the authors of crystallographic publications have followed the same plan, | while others have more or less deviated from it. Many of the figures contained in the works of the present day, it must be owned, are much inferior to Haiiy’s, in point of correctness. It is, however, but very lately, that an intro- duction to a method of projections has been thought wor- thy to receive a place m systematic works on crystallogra- phy, and of these I shall only mention here the T'raité de Crystallographie by Abbé Haiiy, and the Introduction to Crystallography by Mr Brooke. ‘The graphic method, which it is the object of this paper to develop, is that. fol-. lowed by Professor Mohs; it is equally distinguished by the easiness in its application, and the accuracy of which it is susceptible. A. useful representation of a crystal must contain every. thing remarkable and requisite, for identifying it with the original in nature. Its chief object is, therefore, to express the relative position of the faces, and consequently the pa- rallelism of those edges, which are parallel in. the crystals themselves. This object can only be attained, if we sup-. pose the eye of the observer to be at an infinite distance from the solid which is to be represented, in order to have IN TRUE PERSPECTIVE. 487 all those lines parallel which may be drawn from the eye to any of its points whatever. Suppose, now, a plane to cut all these lines, or the visual ray, at right angles ; draw per- pendicular lines from every solid angle of the solid upon that plane, the intersections with it will be the projections of the solid angles; join these points by straight lines with each other, the result will be a figure representing the crys- tal itself. In the art of drawing in perspective, this method is called the Orthographic Projection, on account of the right angle, which the visual ray includes with the plane upon which the solid is represented. Herein it differs from the method fol- lowed by several modern authors, in which it is supposed that the eye of the observer is at once in two different places; but it agrees with the method employed in the works of Haiiy. If the relations of the simple forms among each other be known, according to the crystallographic methods of Haiiy, of Weiss, and others, but, particularly, if attention be given to the derivation of the simple forms from one another, and the laws of their combination, as proposed in the me- thod of Professor Mohs, it will not be attended with the slightest difficulty to draw the figures of the most compli- cated crystals which may occur, if only the projection of one of the simple forms contained in them, have been pre- viously completed ; because the situation of the edges in the compound forms depends solely upon the intersection of the faces of the simple ones, and upon the ratios of certain lines similarly disposed in the single forms, which enter in- to the combination. The first object to be attained, will therefore consist in projecting the figure of a form that may answer this pur- pose; and as the most appropriate, we may select the hexa- hedron, or, in the purely geometrical mode of considering it, the right rectangular four-sided prism, whose sides are 438 ON DRAWING CRYSTALS squares. (Plate XV. Fig. 1.*) It will form the first mem- ber of a series of problems, to be considered in two sections, referring to the method of projecting the simple forms, and the combinations, in which they are found in nature. Section I. OF THE PROJECTIONS OF SIMPLE FORMS. Problem I. Zo draw a Hexahedron. Suppose one of the faces of the hexahedron (Fig. 1.) to be perpendicular to the visual ray. Its projection upon another plane perpendicular to the same line will also be a square, equal to the above mentioned face of the hexahe- dron. Suppose this square (Fig. 2.) to revolve round a line MN, parallel to CD; the points A and B will appear de- pressed in the lines AC and BD, while the length of C D remains unaltered ; the projection of the square, therefore, assumes the appearance of a rectangular parallelogram. But in the hexahedron (Fig. 1.) at the same time, the face C DEF is turned round C D, and the projection of the two faces assumes the figure of two parallelograms (Fig. 3.) If we still continue to revolve the solid in the same way, the projection of A C and BD will diminish in length, while that of C E and DF increases till it becomes equal to C D, when the face CDEF (Fig. 4.) is brought into a plane perpendicular to the visual ray. If the horizontal line M N is not parallel to C D, Fig. 5., the revolution round it cannot give rise to any rectangular * For the figures which accompany this paper I have been indebted to Robert Allan, Esq. younger of Laurieston. They have been carefully exe- cuted in conformity to the rules which they serve to illustrate. * PLATE Xv. : Eng" tor the Wern.

The limits of this change are, the coincidence of B with B™, of A with A™, and of D with D™, which makes the projection of the angle BAC = BDC = 9, that of the angle ACD = ABD = 180°. It is evident that the ratio of A A™ to AT A™ must be equal to that of B B™ to B! B™, and of DD*™ to D? D™, because we may imagine the square A BC D to be part of a rectangular triangle revolving round one of its sides; a triangle produced in the above figure by lengthening MN till it is intersected by BA and BD. But the ratio of At’ At: At’ A™ being equal to that of A™ A : A™! A™, it will also be equivalent to that of A™ C : A™ D", for the equality and similarity of the triangles BA™ A, A A™C, C D™ D, and DD™ B. ‘The ratio of A™C to A™ D"™, and that of B'B™ to AND", depend therefore entirely upon the choice of the position in which the hexahedron is to be represented ; but the ra- tio of A'VA™ to At A™ is a consequence of the two suppo- sitions. If, for instance, we suppose A7'C = 4A™ DD", and AW A™ — +A™D"™, the projection of the square upon a plane perpendicular to the visual ray will be that repre- sented Fig. 6., denoted A’B!D!C. This is the position adopted in M. Mohs’ Works, for the figures of crystals belonging to the pyramidal and tessular systems. The projection of the square A BC D having thus been obtained, upon a plane perpendicular to the visual ray, it is required to find the length of those lines which in the projection appear vertical, and represent the lateral edges of the hexahedron. | Suppose Fig. '7. to be a vertical section, in the plane of the visual ray. The line B B™ in this figure will be the projection of the face BAC D in Fig. 6. If this line be turned round the pomt B™ (which is the projection of the 430 ON DRAWING CRYSTALS line A™D") till BU L (Fig. 7.) becomes equal to A™ ATV (Fig. 6.), the edges of the hexahedron BK!, B™ Gt will assume the situation of B!K; B™G, and the line B™ H, which is determined by drawing GH at right angles upon the continuation of BB", will be the required length of the perpendicular lines in the projection. By the length B™ H, taken upon A™ A™, C'C, B B®, D'™! D", from the angles A1, C, B', D* of the projection of the square, 1s determined the place of the four other solid angles of the hexahedron, which is thus completed, similar to Fig. 1. In order to express these processes analytically, let . A™D"™, the distance of the two extreme edges, be = a; A™ (©, the distance of one of these from the adjacent inte- : a seek rior one, = —; A'Y A™, the height of the projection of the n : Epes terminal square, = — ; and, moreover, the length of an ra NN A. edge of the hexahedron = 6.

Having succeeded in projecting the hexahedron, we find ourselves enabled to resolve a great many problems respect- ing crystallographic drawings, some of which may here be considered, in order to attach to them a few observations relative to certain advantages in executing the projection. Problem II. Yo draw a regular Octahedron. If the octahedron and the hexahedron are brought into a parallel position, the only one in which they are produced by nature in one and the same crystal, the pyramidal axes of one of these forms coincide with the pyramidal axes of the other, and consequently there will exist an octahedron, whose size is exactly such, that its solid angles touch the faces of the hexahedron in their centres. Hence, determine the centres of these faces C, C1, C¥, C™™, Ct’, and CY, Fig. 8., and join them by straight lines, the result will be the octahedron, Problem III. Jo draw a given Isosceles Four-sided Py- _ramid, for instance, P of Pyramidal Zircon. According to Mohs, ain this species is = ./0.8204,* that is to say, the axis of the pyramid P is = ,/0.8204, the side * ¢ Treatise on Mineralogy,’ vol. ii. p. 368. ‘The measurements upon which this quantity depends, were taken upon the small, but beautifully formed, crystals which accompany the native platina, and agree exactly with the results obtained by Dr Wollaston, and Messrs Brooke and Phillips. 492 ON DRAWING CRYSTALS of its horizontal projection being = 1.

Problem IV. T'o draw the Pyramid (P)° of Pyramidal Zircon. We obtain an eight-sided pyramid by the following pro- cess. 1. Produce the axis of the four-sided pyramid on both sides to an indefinite, but equal length; 2. Enlarge the faces of that four-sided pyramid from which the eight- sided one is to be derived; 3. Draw triangles upon them, equal and similar to those of the pyramid, the bases of the _ triangles coinciding with the base of the pyramid; 4. Join the lower points thus determined with the upper apex, the upper points with the lower apex of the lengthened axis; and, 5. Pass planes through every one of these lines and the adjacent lateral solid angles of the original pyramid. The rule for drawing the figure of an eight-sided pyramid will therefore be thus. Project the four-sided pyramid as above. Lengthen the axis A X (Fig. 10) till A'X1is =3 A X, the pyramid required being (P)°. Draw C A™ BE equal, similar, and opposite to C A B? in the prolongation of its plane ; ; in like manner C X"™ BY, C XU™B, CA™B, &c.

The result will be the projection of the pyramid (P)?. The same pyramid will also be obtained by proceeding IN TRUE PERSPECTIVE. 493 upon the following rule. Project the isosceles four-sided pyramid A BC B'C! X (Fig. 11.) as above.. Bisect its la- teral edges, BC in D, C B! in E, &c.

X! of the lengthened axis, and the adjacent ones among themselves. . The latter process, being shorter, is preferable to the former one. It depends upon the property of the eight- sided pyramids, that SD (Fig. 12.) is always equal to m—1 m+1 ramid. For, let AX be =a, A!1X!'—=m.a, A! M will be =5-4, and A! X = a a. .

It is evident, that the projection of any oblique-angular four-sided prism will be as easily obtained as the projection of a scalene four-sided pyramid, 1f we suppose it, in a si- milar manner, to be inscribed into the hexahedron. The prism being a pyramid, one of the axes of which only is infinite, the present case forms a corollary of the preceding one. Let, for instance, the prism (Fig. 14.) which is to be represented, be that, whose transverse section is similar to the base of P-in prismatic Topaz;-or P+-o.

AQ9 The projection of a regular hexagonal prism, which is a member of the rhombohedral system, allows of a similar application in regard to forms of the same system, as the projection of the hexahedron in the forms of other systems. Problem X. Jo draw a We ombohedron. Let, for instance, this rhombohedron be the one whose terminal edge is = 104° 28’ 40”, the same which Abbé Haiiy considered as the primitive form of calcareous spar. Its axis is = 1.5 — 2.95.° Draw the regular hexagonal prism, whose sides are squares, in the position fixed upon, Fig. 5. Produce the la- teral edges, till A A™ is = 3 A A‘, equal to the given axis of the rhombohedron. Take one-third of the length of these lateral edges alternately from the upper and the lower hexagon, and join the points A™, Bt, C™, D!, H™, FY thus determined among each other and with the centres M, Mt‘ of the adjacent terminal hexagons by straight lines The result will be the projection of the given rhombo- hedron. The projection of the actual fundamental rhombo- 7 hedron of rhombohedral lime-haloide is obtained, if, in- stead of taking A A™ = 3 A A*, we substitute the value <= /2.1895 A Al If MM'or AA™is= AA!. ,/45, the projected solid is the hexahedron. If O'G', in Fig. 2., is = 0, the method of drawing a rhombohedron becomes very simple, since it requires only to draw the vertical lines representing the projections of the lateral sides and the axis of the hexagonal prism at the regular distances (at equal distances, for A’ P? = 3A? G?, in Fig. 2.) from each other, and cross them at right angles by four equidistant horizontal lines, whose intersections Lice 500 ON DRAWING CRYSTALS with the former determine the situation of the angles of the rhombohedron, as it appears from the inspection of the 6th figure. Problem XI. Jo draw a Scalene Six-sided Pyramid, Sor instance, (P)* of rhombohedral Lime-haloide, or the * variété métastatique” of Haiiy. Having completed the projection MABCDEFM=* (Fig. 7.) of the rhombohedron R, take NM = M M* = M'™N', because here the number of derivation is = 3, which requires NN! tobe =3MMI!._ Join the ends of the lengthened axis with the lateral angles of the rhombo- hedron by straight lines; the result will be the projection of the required scalene six-sided pyramid. : Problem XII. Yo draw an Isosceles Six-sided Pyramid, Jor stance, P, or that which belongs to the Rhombo- hedron R of the same species. Project (Fig. 8.) the rhombohedron A BB'BUCCIC™X, and take AM = X'X. Draw CC™, C1C1", C™CY pa- rallel to the axis AX, and lengthen the lines B M, B' M, B™ M, till they intersect the former in C!Y, CY, C™. Join the points B, C™!, Bt, Ct’, B™, CY, with each other, and with the points A and X%, equidistant from M, the result will be the projection of the isosceles six-sided pyramid P, as it is represented in Fig. 9. The preceding cases will suffice for obtaining the pro- jection of any simple form we may desire, if the rules laid ? down in this respect be properly seconded by a knowledge _ IN TRUE PERSPECTIVE. 501 of the relations of the forms themselves, and of the rela- tions they bear to each other. It will be useful, however, to illustrate, by a few examples, the method of drawing the figures of combinations. Section II. Or tue PROJECTIONS oF CompouND Forms. Compound forms or combiations, in general, are those crystalline figures, which at the same time shew the faces of two or more simple forms. Every one of these may be obtained by sufficiently enlarging those faces which, in the compound form, are equal and similar to each other. The form of the combination may be defined to be the space included at the same time within all the forms. entering into the combination. Hence the method of representing them in its greatest generality, will require to lay down, in the parallel position, the figures of all those simple forms which the combination contains, and to determine that part of them which, if they intersect each other, is not excluded by any one of these simple forms. In most cases we may dispense with proceeding upon this long and very often tedious way, but it will be necessary to shew it in an ex- ample. Problem I. To draw the Combination of the Hexahedron and the Octahedron. Project the two simple forms in parallel position, so that their centres may coincide in M, Fig. 10. If we draw EF parallel to DB, and IK parallel to LP, through the centres of the respective edges of the hexahe- 5O2 ON DRAWING CRYSTALS dron, these lines will determine the situation of the points N, N™, and Nt, N™ in which the edges contiguous to one of the angles of the octahedron rise from the planes within which the hexahedron is contained. The part ANN'N"™N"®, situated beyond the face TU V W of the hexahedron, will therefore be cut off by this face, and not appear in the combination at all. The same will be the case with all the other solid angles of the octahedron, and the combination itself will be contained under eight hexagons, the residue of the faces of the octahedron, and six squares, being the residue of the faces of the hexahedron. The same result may be obtained by a shorter process, thus: Project the figure of the octahedron, take A N' = Rt L = AL, AN = 5 2 = ~ AB, 1h su B=-—LB, and draw NI N®, S S", R3 R™, which are the intersections of the face A BL of the octahedron with the three adja- cent faces of the hexahedron. ‘The same process applied to all the edges of the octahedron gives the intersections of all the faces of the two solids, which being expressed by straight lines, jeele the projection of the combination wanted. Having obtained the figure of a double combination, it will be easy to add the faces of a third, then of a fourth simple form, and so on; and here, as well as in the pro- jection of the simple forms themselves, we may often take advantage of many circumstances, which will offer them- selves to our attention in the practical attempt of laying down the representations of crystals, in the proportion of our actual information in regard to the various departments of crystallography. IN TRUE PERSPECTIVE. 503 Problem II. Vo draw the Rhombohedral Combination R. (P)>. R+2, of the Species of Rhombohedral Lime- haloide. Before all, it is necessary to fix the relative extent which ithe faces belonging to the different forms are meant to pos- sess, in order to ascertain which of the simple forms is to be projected first, and the others applied to it, according to the rules of derivation and of combination. Nothing is more easy, if the combination contains only a few simple forms; but it requires some practice to find out the best order in which one of the simple forms is to be added after the other, if the combination contains a great number of them. A short time, however, devoted to the projections of the simple forms themselves, is the best assistance for those who intend to occupy themselves with representing combi- nations. In the present case, it will be most advisable to begin with the scalene six-sided pyramid (P)*, and the process itself will therefore be as follows. Project the pyramid (P)* or ABC DEFG X, Fig. 11, according to the rules given above (Sect. I. Probl. XI.) The edges of combination between R and (P)* are paral- lel to the opposite terminal edges of the rhombohedron, and to the lateral edges of the pyramid. ‘The poimt Ct! in ‘which one of the faces of R intersects the edge A C of the pyramid, and consequently the ratio of A Ct to A C having been determined, it is required to draw the edge of combi- nation C1 D parallel to the lateral edge C D of the pyra- mid, and likewise C1 Bt parallel to CB. By this process the ratio of A Bt : AB becomes equal to that of AC7: AC, and so all round, till all the points B! C! D' E! F' G! have been determined, and those lines drawn which join these points with each other, and represent the edges of combi- 304 ON DRAWING CRYSTALS nation between R and (P)°. A line M!NI parallel to C? D*, or C D, or to MN, the edges of the rhombohedron R, and passing through the point B, denotes the direction of one of the terminal edges of R; its intersection with the axis A X, or At, is the apex of the rhombohedron itself, which enters into the combination. The lines A! Dt, A! F! joming this apex with the upper solid angles of the combi- nation, complete the figure on this side of the centre; on the opposite side of which the same process must be gone through. The third form to be combined with the combination of R and (P)* is R+2, an acute rhombohedron, whose edges of combination with (P)* are parallel to the more acute terminal edges of the pyramid. A face of this rhombohedron, passing through an arbitrary point O of the obtuse terminal edge A C of the pyramid, will there- — fore produce the edges of combination O P and OQ, being the intersections of that plane with those of the pyramid A BC, and ACD. In order to find the point §, where the face of R+2 intersects the lower opposite edge C X, take PR = RQ, and draw OR, which, duly length- ened, will intersect C X in 8. The face OPS Q will re- present one of the faces of R+2, as it appears in the com- bination. There are six of these faces, three of them in- clined to the upper apex, the three others inclmed to the lower apex; one of the latter is O' P'S! Q! in the figure. But the faces OP SQ and O! P'S'Q! intersect each other in the line Z Z1, which line is the lateral edge of R+2, and, as such, parallel to O P and O' P', the edges of com- bination between this rhombohedron and the pyramid (P)*, or A B and X E the terminal edges of the latter form it- self. The result, in completing the combination, by draw- ing the four remaining faces of R+2, is the form repre- sented in Fig. 12. IN TRUE PERSPECTIVE. 505 Problem ue To draw the Pyramidal Combination P. (P)°>. P+3. P+o, of the Species of Pyrami- dal Zircon. Project the hexahedron ABC DA" BUC" D® (Fig. 13.) according to the rules given above (Sect. I. Probl. I.). Take A A'=3A A™. 0.8204 = CC'= DD! = BB. By joining the points A with D, and B with C, determine the situation of M, the centre of the square ACDB; and, finally, draw the lines M Bt, M At, &c. and Bt Al, A? C}, &e. The result M Bt AC! D! is one part of the isosceles four-sided pyramid required, which, if likewise applied on the opposite side of the axis M M?, will complete the com- bination of P with P+-o. The length A'A™, &c. is quite indifferent, and depends upon the relative size of the same lines in those natural combmations which are to be repre- sented. The next form to be added is (P)>. Rake © Oj=2CM,. C1 P= HCtAl, CLP) = 3-0) DI, ; 1 and C'Q = 2 CC’, or in general CO=—CM, Cir = = Cr AY cr == De and C.Q =~. CC.” and draw the lines OP, OQ, OP, and PQ, HH Q; the faces OPQ, OPQ will be those parts of the faces of (P)°, which appear in the combination. This becomes quite evident, if we consider the dimensions of that eight-sided pyramid, and its relations to P. Since (P)* belongs imme- diately to this four-sided pyramid P, the edges of combina- tion between the two forms must be parallel to the opposite terminal edges of the latter, O P therefore parallel to M A‘; and if this edge of combination be supposed to coincide 506 ON DRAWING CRYSTALS with the terminal edge M A‘, that part M M™ of the axis, which corresponds to its terminal edge MC™, must be equal to three times the part M M!, which corresponds to the terminal edge M C! of the four-sided pyramid. ‘The last is indicated by the exponent 3 in the sign of the eight- sided pyramid. If the same process, by which the faces OPQ and OP'Q have been obtained contiguous to the angle C1, be applied to every one of the other solid angles similarly situated, all the faces of (P)*, sixteen in number, will be produced, and thus the triple combination P. (P)°. P+ o completed, as it 1s represented in Fig. 14. | The fourth and last of the ell forms to be added to P+3.
