Died on the 30th of March, 1857, at his house in Granby-row, Dublin, Robert Ball, LL.D., one of the Editors of this Journal. Doctor Ball was Secretary to the Queen's University, and Examiner to the Board of Commissioners of Civil Services for Ireland. The relation in which he stood to the studies of Zoology and the kindred sciences is but imperfectly suggested by his titles in connexion with the principal public scientific bodies in Dublin, where he resided. He was Treasurer of the Royal Irish Academy of Science ; Secretary to the Royal Zoological Society ; Director of the University Museum, and President of the University Zoological and Botanical Association, in Trinity College ; Vice-President of the Geological Society ; Member of Council of the Royal Dublin Society, the Statistical Society, etc. And these were not honours sought by him for the orna- ment of a name, but offices imposed upon him by the public appreciation of his superior fitness, and duties which he fulfilled with the energy, discre- tion, unselfish kindliness and strong sense of honour, which were so eminently characteristic of him through life, and in all its relations. The Royal Irish Academy, with other scientific societies, and not those only with which he was directly connected, have testified to the blank he has left, by adjourning, without entering on any scientific proceedings, at their meetings next after his decease. Doctor Ball was President Elect of the Section of Zoology and Botany of the British Association for the Advance- ment of Science, in their meeting of 1857, when he was taken away in the vigour of life, and the full career of social usefulness. Of the colleague and the friend, our own more especial loss, we cannot trust ourselves to speak now particularly. Eds. N. H. R. THE NATURAL HISTORY REVIEW. JjWriefow. A Synopsis of the British Diatomacej:, with Remarks on the Struc- ture, Functions, and Distribution; and Instructions for Col- lecting and Preserving Specimens. By William Smith, F.L.S., Professor of Natural History, Queen's College, Cork. Vol. II. 2 Is. It is a pleasant thing to find one's anticipations of good realised. Some months ago, when noticing the first volume of the " British Diatomaceae," and finding it a book deserving of our best wishes and calling from us no ordinary meed of praise, we deemed justified in venturing a prophecy, from the earnest then afforded, that the second volume would in no respect fall behind its forerunner. We have prophesied well and truly, for our antici- pations have not only been fully realised, but have even been exceeded » and we rejoice in being able now to call the attention of our readers to the second and concluding volume of one of the most useful works which has of late years been placed in the hands of the investigator of the microscopic forms of organised existence. The author has reserved for the present volume some very important topics connected with the general history of the Diatomaceae — their highly curious reproductive phenomena, their exact nature, and the status they hold in the organic creation ; the characters to be relied on in the determi- nation of genera and species, and the laws by which they are governed in their Geographical distribution : all of which are well discussed in an in- troduction to the systematic portion of the volume. On the subject of the reproduction of the Diatomaceae especially, Mr. Smith has rendered us acquainted with some new facts of much physio- logical importance, and tending to throw considerable light on the import of the curious phenomenon of " Conjugation." It is now about eight years since Mr. Thwaites announced the very significant fact that he had observed vol. iv. *~* B 2 REVIEWS. in a species of Diatomacese a process entirely similar to the " conjugation" with which botanists were already familiar, as occurring in several of the green freshwater algae. In Enotia turgida, in which he first witnessed this phenomenon, two of the microscopic unicellular plants, of which this species consists, were seen to approach one another, and pour out from within their siliceous skins, which opened for the purpose, the whole of the soft, semi-fluid contents of their bodies, mingling the one with the other, and leaving behind nothing but the empty shells. The mingled contents soon shaped themselves into two cylindrical masses, or " sporangia," which gradually became more and more similar to the parents, encasing them- selves, like them, in a flinty shell, and ultimately differing from them chiefly in their very much larger size. We well remember hearing Mr. Thwaites's paper read for the first time, at one of the meetings of the British Association ; and the interest which the botanists then present took in so important an announcement will not easily be forgotten ; for it was deemed that the point was at last discovered which decided the true relations of these enigmatical organisms ; that their supposed animality was a simple delusion ; and that the territory of the Diatom must, without further demur, be handed over to the dominion of Flora. With the exception of Mr. Thwaites's subsequent statement of some addi- tional instances of the process just described, and his discovery of the interesting fact that in certain species the " sporangium" repeats itself by division, our knowledge of the conjugation of the Diatomaceas had rested pretty much as he left it. It was still evident, however, that something yet remained to be determined, and the true import of the sporangial frus- tule, the immediate result of the curious conjugation, continued unex- plained. When a subject like the present falls into the hands of a patient and laborious observer, we may safely expect some results ; and it cannot, therefore, be matter of surprise that Mr. Smith is enabled, in the volume before us, to present us with numerous additional instances of conjugation, as well as confirmations of the very accurate accounts of Thwaites, making in all no less than twenty-seven distinct cases, which have all come under his own observation. But a still more important step towards the determination of the true significance of Conjugation, than that suggested by the mere accumulation of instances, has been made by Mr. Smith. The ultimate destination of the " sporangial frustule," the immediate product of the conjugative act, had BRITISH DIATOMACEiE. 3 hitherto remained involved in great obscurity, the known facts admitting of nothing but loose sunnises of little scientific value. Some phenomena, however, have come under the observation of Mr. Smith which seem to go far towards a satisfactory determination of this important point. He has rendered it, indeed, almost certain that the contents of the sporangial frus- tule ultimately resolve themselves into a brood of young Diatoms, exactly repeating the form of the original conjugating individuals — an observation which we do not hesitate to say is one of the most important which has of late years been made in the physiology of plants. The difficult subject of the determination of species in the Diatomacese, and the selection of the characters on which the systematist must rely in the construction of his natural groups, is well discussed ; and it is shown that mere difference of size, and even slight difference of outline, cannot be depended on as indicating a specific separation of two individuals. The character of the Striation and the arrangement of the Endochrome are the points on which our author chiefly relies ; and in this we entirely agree with him. We cannot, however, quite make out in what rank he would place habitat, when he speaks of it as assisting in the determination of species. If he means that it should be considered as a character forming a "consti- tuent part in a diagnosis, we cannot assent ; but it is probable, after all, that what he really intends to convey is simply that the fact of two given specimens being found, one in the sea, and the other in fresh water, will afford a priori reasons for suspecting a difference of species, and will lead the observer to seek for valid specific characters in the striation and the arrangement of the endochrome. If this be his meaning, we agree with him, and believe his suggestion to be one of much practical value. The very wide geographical distribution of the species of Diatomacese is a curious fact in their history. We find them, indeed, scarcely influenced by those external agencies which set such well-marked boundaries to the areas occupied by organic beings generally. The following account of their distribution will give the reader some idea of this feature in their economy : " Of fresh-water species frequent in the British Islands, the following seem almost cosmopolitan, viz. : Synedra radians, Pinnularia viridis, Pinnularia borealis and Cocconema lanceolatum. Gatherings from many localities in Europe, from Smyrna and Ceylon, from the Sandwich Islands, New Zealand, and New York from the loftiest accessible points of the Himalaya in Asia, and the Andes in America, have supplied specimens of these forms. ** Navicula serians abounds in all our mountain bogs, and is equally common in the marshes of Lapland and America. " Epiihemia gibba is an inhabitant of the Geysers of Iceland and the lakes of Switzerland. '• The South Sea Islands supply Stauroneis acuta, and Ceylon Synedra ulna • 4 REVIEWS. while Stauroneii pkcenicenteron is equally abundant in Britain, Sicily, and Nova Scotia. " These notes of localities will give some idea of the wide distribution of our fluviatile Diatomacese; more numerous gatherings would, no doubt, greatly extend the list, and the following circumstance will show how generally our commoner British forms are diffused throughout European localities that have been care- fully examined. During a tour in Languedoc and the Auvergne, in the spring of 1854, I made upwards of forty gatherings from the rivers, streams, and lakes of the district I traversed ; in these I detected one hundred and thirty species, described in the present work, and but one form not yet determined as indigenous to Britain. If this be the case with a district, much of whose Phanerogamous flora is so different from our own, it bears out the view I have taken, that these organisms eojoy a range of distribution far more general than the higher orders of plant life. " Nor is the distribution of marine species less notable for its extent and uni- formity. Coscinodisciu eccentricus and Coscinodiscus radiatus range from the shores of Britain to those of S. Africa. Grammatophora marina and Grammato- phora maeilenta are found in almost every marine gathering from the Arctic Ocean to the Mauritius. Stauroneis pulchella, Cocconeis scutellum^ and Biddulphia pulckella are equally abundant on the European, the American, and the African coasts ; while Rhabdonema adriaticum belies its name by its occurrence in the Indian, Atlantic, and Pacific oceans. During the researches already mentioned in the South of France, I made several prolific gatherings on the shores of the Gulf of Lyons ; but of thirty-three forms occurring in these, Hyalosira delicatula Kuetz. was the only one not familiar to me as a British species." In our notice of the first volume of "The British Diatomaceae," we ventured to predict the rapid discovery of new forms, which would result from having so valuable an aid placed in the hands of the investigator. Our prophecy has turned out true. In proof of this, we have only to refer to the appendix of the present volume, where the reader will find no less than seventy-two species described, belonging to genera contained in the first volume, and all of which have been discovered by various observers since that volume was published. We cannot conclude the present notice without a word regarding the thirty-seven plates with which it is illustrated. These plates, like those of the former volume, are engraved by Mr. T. West. They are even superior, as works of art, to the plates contained in that volume, and deserve our highest praise as specimens of Natural History iconography. G. J. A. Elements of Entomology ; an Outline of the Natural History and Classification of British Insects. By William S. Dallas, F.L.S. London : Van Voorst. A work bearing the above title is now in course of publication. It is to be completed in fifteen monthly parts, three of which have already appeared. When we add that they are brought out at the very low price ELEMENTS OF ENTOMOLOGY. 0 of sixpence each, it is obvious that the publisher must anticipate a large sale ; for nothing else would enable him to meet the expense of publication, and to realise a profit. This fact is worthy of note ; for, as publishers must in their undertakings have reference to the public wants and wishes, we may infer that Mr. Van Voorst considers that he can now appeal to a circle of readers very different in extent from that to which such a pub- lication could, even a few years ago, have been addressed. We have, therefore, in this, an evidence of the increasing public desire for zoological knowledge, especially in one of its most fascinating departments. We prefer waiting until the work is complete, before expressing any critical opinion on its merits. At present, we would do little more than announce its existence, and convey to our readers, so far as these numbers enable us, an idea of the course pursued by the author. He has not given any " preface" or " introduction ;" so that we have no explanation pre- sented to us of the plan he intends to adopt, or the precise views which it is his intention to bring forward and elucidate. The subjects, successively taken up in the several chapters, are the only landmarks which indicate the general direction of the road along which Mr. Dallas proposes to guide the young Entomologist. " What is an Insect ?" is the question asked and answered in Chapter I. The " Structure of Insects in general" occupies Chapter II. This is followed by " Sexes and Transformations" — " Classification and Nomen- clature." Chapter V. is devoted to the Coleoptera ; and we may presume that the other orders will follow in regular sequence. The style is simple and perspicuous, and the young student who reads these " Elements of Entomology" will never feel a doubt as to the author's meaning. It is clear and intelligible throughout. But it would be doing injustice to Mr. Dallas if we did not add, that the didactic style is occasionally forsaken, for one more congenial to youth, and not without attraction even to those of advanced or declining years. As an instance, we would refer to his description, at page 65, of a Lon- doner's spring ramble, and its concomitants, including the Brimstone but- terfly (Gonypteryx Rhamni) and the Tiger beetle (Cicindela campestris). To join in such a walk, we would throw down our pen, lay aside our spec- tacles, and forsake our library and easy chair ; for we reside in a locality where the Tiger beetle is unknown, and where we have lived for more than twenty years without our eyes having been " gladdened," during all that time, with the sight of a Brimstone butterfly on the wing. R. P. REVIEWS. Ornithological Synonyms. By the late Hugh E. Strickland, M.A., F.R.S., &c. Edited by Mrs. H. E. Strickland and Sir W. Jardine, Bart. 8vo. London : Van Voorst. 1856. 12s. 6d. It is impossible for any person who has not entered well into the study of practical Ornithology duly to appreciate the difficulties attending it ; owing, mainly, to the reckless way in which Synonyms have been multi- plied. Sir W. Jardine, in the preface to the work of his much-lamented son-in-law, Mr. Strickland, while he alludes to the many causes which have occasioned the multiplication referred to, does not, we think, bear sufficiently heavily on the class of persons who seek to be enrolled in the list of naturalists on the score of altering established nomenclature ; for it is not possible to imagine, in some cases, any other motive. Mr. Strickland in some of his published papers, viz., in Mag. Nat. Hist., Vol. VIII. , p. 636, and Vol. I., n.s., p. 127, commented warmly and strongly on this practice. For its prevention, it was proposed, 1st. That no name should be acknowledged in Natural Science, until it had been submitted to, and approved of by, a Scientific Committee to be elected from the Savans of Europe. 2nd. Any name thus sanctioned not to be altered without the consent of the aforesaid body. Just as our law requires that no man shall change his own family name, without obtaining an approval, under the sign manual of the Queen, and recording the same in the office of arms ; and this sanction, be it observed, is only given on fair reasons being shown that the change is pro- per and desirable ; in the absence of such reasons it is withheld. We fear, however, that the organization of such a committee is impracticable. Another scheme proposed is to suppress all notice of the introducers of useless names ; but this will not do, for several reasons ; principally because it would prevent the correction of errors. We think a plan (a Caustic one) may be adopted which would tend to correct the abuse in question, viz., that when authors, who are well assured of what they are about, find it necessary to quote those of whom we complain, they should, after each improper or needless Synonym insert the word " Silly," or " Ignorant," or such other qualifying addition as the case may seem to require. But we have wandered from our immediate subject. We had the hap- piness of well knowing the estimable author, lost to us in his prime, (he was dashed to pieces by a passing train whilst absorbed in the contempla- tion of a geological section in a railway cutting ; ) we have been engaged with him in devising rules for the improvement of nomenclature ; and though we cannot take much credit for work done individually in this matter, we ORNITHOLOGICAL SYNONYMS. 7 know how earnestly and usefully he laboured. We have also been with him when employed in collecting materials for the work now before us, and have admired the industry, acumen, and learning which he displayed ; and while we rejoiced that so necessary a work was in such competent hands, we felt somewhat grieved that the impertinences to which we have referred should occupy so much of the attention of one who was well qualified to reform the whole system of Ornithology. We are aware that he had not trammelled himself with artificial systems, but that, taking birds as he found them, he sought in their obvious affinities the right key to their classification. Would that he had lived to work this out. We have just had the authority of one of our eminent ornithologists for saying that no work, such as that now before us, has been so well done. The unravelling of Synonymy is a labour of science which requires much learning, exemplary patience, and great impartiality ; while to ordinary persons it shows no considerable results, it is most valuable to scientific men, especially in economising of time, and enabling those who have but little leisure to do good service. We cannot, therefore, be too grateful to persons whose erudition and self-devotion are applied to the accomplishment of such works as that of Mr. Strickland. Notwithstanding what we have said, it is obvious that it is not a book from which extracts can be here given ; but some notion of the labour attending its compilation may be attained when, without counting the time spent in museums, collating collections, corres- pondence, &c, it is known that he has referred to about seven hundred works of authors in various languages. One use of the work is its serving as a means of reference to the several authors quoted. It must not, however, be depended on as an Universal index, as we find, doubtless for some good reason, that no reference is made to the authors who have noticed some of the recent additions to our list of Accipitres, though these authors are quoted in ordinary cases. On the whole, we strongly recommend the book, and we think no ornithologist should be without it. R. B. General Outline of the Organization of the Animal Kingdom, and Manual of Comparative Anatomy. By Thomas Rymer Jones, F.R.S., Professor of Comparative Anatomy in King's College, London. Se- cond Edition. 8vo. London: Van Voorst. 1855. £1 lis. 6d. It is now about fifteen years since the first edition of Professor Rymer Jones's " General Outline of the Animal Kingdom" was placed in the hands 8 REVIEWS. of the naturalist. It was by far the best book on the general structure of animals then available to the English reader ; and its lucid and graphic descriptions, and the beauty of its intercalated wood-cuts — a mode of illustration far from common at that time — conferred on it no ordinary popularity, and rendered it an universal favourite with both professor and student. Years, however, passed on, and zoologists continued to ply their work with energy and zeal. Hosts of active investigators were busy, both at home and abroad, with the scalpel and the microscope ; the dredge was drawing from the deep new Invertebrate forms, to supply the missing link s in the great chain-net of organization, and fresh light was being shed on the nature, relations, and significance of Vertebrate structure. It can no longer, therefore, be matter of surprise that the first edition of the work be- fore us should have been passed in the great race of discovery, and that other books fresh with the results of the physiological investigations of the day should have been taking its place on the shelves of our libraries, and in the hands of our students. A new edition was, therefore, loudly called for, and has accordingly appeared; and it only remains now to be seen whether it has overtaken the progress of science, and whether the " General Outline of the Animal King- dom" is once more, after its long interval of rest, a true exponent of the actual state of Anatomical Zoology. "We believe we may safely affirm that the present volume is a valuable addition to the library of the zoologist, and one with which every student of Comparative anatomy will do well to make himself acquainted ; and yet we do not think that in all respects it has come up to the actual state of science. We can refer to many of its chapters as excellent, and as containing succinct and admirably given statements of recent investigations made in various departments of physiological research — statements conveyed, too, in that peculiar style of graphic description, in which we think the author stands almost without a rival. Among the subjects in which the present volume has greatly the advan- tage over its predecessor, we may instance the introduction of much new matter into the chapter on the Protozoa ; of many of the results of Steen- strup's and Van Beneden's researches into that on the Entozoa ; the enlargement of the chapter on the Echinodermata, by the addition of some of Mueller's important discoveries in the development of these animals ; of that on the Annelida, by the discoveries of Milne-Edwards and of Dr. GENERAL OUTLINE OF THE ANIMAL KINGDOM. 9 Williams ; and the incorporation of the Morphological views of Owen with the chapter on the Vertebrata. With all these improvements, however, we still believe that the book has fallen short of what it might be. Why, for instance, do we hear nothing of the researches of Stein on the Infusoria, and the remarkable " Encysting process" and " Acineta forms," undergone by these animals ? Why are we told nothing of the Hectocotylus of the Cephalopods, whose history con- stitutes one of the most remarkable features in the present phase of zoolo- gical science ? Why are the Bryozoa left with their old pseudo-relatives, the Radiata ? Why are the Suctorial Crustacea divorced from their true relations, and placed in the same connection ? Other instances of a like kind might be mentioned in which our author has not fully represented the present state of zoology; and yet, always making allowance for these defi- ciencies, we have no hesitation in recommending the second edition of the ;' General Outline of the Animal Kingdom" as a good and useful book, with which the student will have no reason to regret having furnished himself. G. J. A. The Entomologists' Annual, for MDCCCLVII. 12mo. London : Van Voorst. Price, 2s. 6d. Our gay-looking little contemporary has just arrived in time to receive a rapid inspection, but no more. It professes to be the old-established, '' original" edition, in contradistinction from two other forms in which the same contents are simultaneously published ; but it is most decidedly smaller in size, so the public must try to accept in simple faith the counterbalance of solid value implied by its not very bashful motto, " Vires acquirit eundo." This latter principle seems to be that on which the Editor chiefly builds his expectations of success in so energetically and indefatigably endeavour- ing to urge his favourite theme on the notice of the community ; yet we cannot conceal an apprehension that the desired elevation, when reached, may prove a giddy one. In other words, that the novelty of rapidly appearing and naturally ephemeral publications may wear off, and the pas- sing interest they excite disappear like the effervescence of all popular favour. We are not going to say a word against the desire to render Natural History popular. We are most anxious it should be so ; but it does look, in our estimation, very like absurdity to expect a book like the Annual to be made the ornament of the drawing-room table, and to publish a grand C 10 RK VIEWS. " Library edition" of it accordingly. One of our friends would respectfully suggest to the Editor that when the Annual reaches perfection (and is thus the greatest marvel of the age), he should publish it in Royal Octavo, with ample margins, and figures of every species ! Another enigma to our short-sighted views is the actual or probable use of parading such a show of " names of British Entomologists," while it is confessed that a great number of them are only schoolboys. Our friend* the Editor, as well as divers other leading men, constantly complain of the carnal motives — covetousness, desire of notoriety, &c. — which influence many of "the brethren ;" but is not this the very way to encourage those false in- centives ? Would it not be better to have our ranks even fewer than they are, than be recruited by mere aspirants after vain-glory ? It is our firm belief that a work like that of Kirby and Spence, which silently and unobserved developes the really innate — not acquired — tastes of the young for the subject of its charming details, has done more good, and will yet do more good, than all the periodical publications of the pre- sent day put together. Why, in the latter the names of the collectors are now of nearly as frequent occurrence to the eye as the names of the species alluded to ! And hence we are glad to see Mr. Stainton turn his attention to pro- ductions like the " Educational Sheet of Butterflies,'' of which a copy has been sent us. The woodcuts are admirable, and the details judiciously compiled. The plate in the Annual, too, is very good, indeed, this year. This number also contains some papers of a superior class. Dr. Hagen's monograph of the British Dragonflies will be found a great boon to those who wish to extend their researches beyond the "fashionable" limits of the two favourite orders ; and Mr. Janson's interesting discoveries in the ant-hills will open a new field in the already well-worked department of Coleopterous re- search. Among the beetles he announces fifty-four new species added to the British lists this year — a fact that will startle many, until they have perceived that a large number of the novelties were lying in the arcana of Mr. Walton's collection, and unheard of till the recent publication of his Catalogue of the Curculionidae. The Diptera have gained a slight acknow- ledgment this year, in the form of Notes and Queries by Mr. Wilson Saunders ; and, on the whole, we are disposed to agree with Mr. Stainton in thinking that Entomology is making some progress, though we are so strongly opposed to the stimulus of anything like hothouse pressure. REVIEWS. 1 1 Typical Forms and Special Ends in Creation. By Rev. James M'Cosh, LL.D., and George Dickie, M.D. One Volume 8vo. Edin- burgh : Constable and Co. 1856. The aim of the authors of this treatise is to prove by examples and reason- ing that the world is made after a General Plan, to which every object is made to a certain extent conformable ; and that there is, at the same time, " a principle of Special Adaptation, by which each object, while constructed after a general model, is accommodated to the situation which it has to occupy, and a purpose which it is intended to serve." For many years British writers on Natural Theology were in the habit of drawing their arguments chiefly from the indications in nature of special adaptations of parts or organs to particular purposes. But when, at a more recent period, the evidences began to be discerned of a certain rela- tion to some general type or types of structure, which has constantly per- vaded all organized nature, controlling the kind and extent of those altera- tions which the individual parts and organs undergo in order to adapt them to their particular functions and conditions ; there were not wanting writers who seized upon this discovery as a weapon to overturn the proof of intelligence and design, derived from the instances of special adaptation, and stoutly maintained that the utmost which a philosophic eye can re- cognise in nature is a general harmony of structure, without any evidence of such designed relation to the wants and welfare of particular organized beings. In opposition to their views, the authors argue that the preva- lence of such a general order is, in itself, a distinct proof of the wisdom and design of some creative agent ; nay, further, that if the instances of special adaptation be more obvious and striking arguments to common un- derstandings, yet the evidence of a more comprehensive, or an universal plan, affords the most unanswerable demonstration of the attributes of the Creator, who conceived and has carried out that plan, throughout the immensity of Universal Space, and through all the incalculable Ages of the World's unwritten history. And while Adaptation and Uniformity are both alike adverse to the opinion that those objects can be the works of chance, the special adapta- tions show that the order is not the result of an unreasoning Necessity. Taken together, as mutual complements, " they exhibit to us an enlarged wisdom, which prosecutes its plans methodically, combined with a minute care which provides for every object and every part of that object. They disclose to our faith a God who sees the end from the beginning, and who 12 REVIEWS. hath from the first instituted the plau to which all individual things and events have ever since been conformed." Every object and every event must be the effect of some creative or im- pulsive power. Chance and Design are, of themselves, equally inefficient to produce any effect. They are merely words used to express the presence or absence of Intelligence and Intention in the Being by whom that power is exerted. The existence of the Power must be admitted : to deny it would be a contradiction in tenns. The only question remaining is whether or not that Power is connected with intelligence, and has been directed to an End. But the argument drawn from the special adaptation seems to a fford a conclusive answer to this question. By means of this, we are able, in a way of induction, to arrive at a ratio of probability, indefinitely increasing, until this may be considered equivalent to a moral certainty. The study of the Eye alone would go far to establish a probability of this degree. Its exquisite construction, as an optical instrument, the contriv- ances by which that delicate organization is protected from contingent dangers, and by means of which it can be instantaneously turned in every direction, and adapted to near or distant vision, might alone convince us of the highest degree of wisdom and benevolence in the Maker. And this argument becomes immeasurably enhanced when we find various species of animals possessing organs of vision, formed on the same grand type, but with differences adapted to their different habits, and to the conditions in which they are placed. The authors give numerous illustrations of the manner in which the wants and instincts and organs of various animals are adapted to each other and to the circumstances of their existence ; and a reference to the most ancient fossils shows that the prevailing adaptation which we perceive in existing animals is not to be explained by the lapse of time having brought about the extinction of other races in which this adaptation had not place : — " It is seldom that the geologist finds a fossil plant or animal entire; most commonly he falls in with only a fragment, yet this fragment, if it be a significant one, enables him to reconstruct the whole. The process of theoretical reconstruction is conducted on those very principles of homology and teleology which we have shown to pervade all organic nature. The palaeontologist supposes that there were answerable parts in the genus or species, and a series of homotypes in the individual ; and he goes on con- fidently to supply the wanting parts on the principle of homology. He proceeds, too, on the principle of final cause ; he supposes that the part had an end to serve, and that there would be a conformity of every other TYPICAL FORMS AND SPECIAL ENDS. 13 organ to fulfil that end. By means of these two principles he can often, when he is in possession of but a fragment, make the entire organism stand before us with all its harmonies and its fitness. When at any time he falls in with an entire fossil organism, he finds that these principles are verified, and that he is entitled to proceed on them." — p. 312. The authors animadvert upon two common and nearly-related mistakes which are sometimes made respecting the principle of development. It has been supposed, on the one hand, that, through successive Geological periods, there has been a progressive improvement in organic nature. This is not the case. The plants and animals of the earliest ages were as well suited to the conditions by which they were surrounded, and the uses which they had to serve, as the plants and animals of the present day, although they would not be so well fitted, if they existed now, to the present state of the earth, or to supply the wants of its chief inhabitant, man. But they served their purpose before they passed away ; and they may be said to continue to serve one still, in furnishing another striking example of the infinite wisdom and beneficence of the Creator. They afford a warning, too, how cautious the wisest ought to be, — though they are not the wisest who most want this caution, — not to presume that anything is useless, or even that the uses of it which they are able to discern must, therefore, be the most important actually. Let us imagine, for a moment, one of the angels, who may have surveyed the earth at an epoch long anterior to the creation of man, to have been asked concerning the utility of the luxuriant tropical vegetation which then flourished upon the earth. He might probably have answered, by pointing out many important purposes to which it was then subservient. But no reasoning powers, of which we can form any concep- tion, could have enabled him to predict that those plants, having undergone certain natural changes in the course of time, would become coal, and in that shape be a most important agent in promoting the comfort and mul- tiplying the effective force of other beings afterwards to be placed upon the earth, and of a nature only a little lower than his own. The second mistake which these authors have exposed is that of sup- posing that man, in any stage of his existence, is like a lower animal in its more advanced state, as if the lower animal were an inchoate man arrested in its development. It is true that animals, ultimately the most dissimilar, present comparatively few and minute points of difference in the embryo ; their distinctive characters, first the more general, then the more special, becoming more and more pronounced, in gradual succession, as they advance towards their ultimate development. Conversely, we can conceive the dif- 14: REVIEWS. ferences continually to diminish in re-ascending towards the first origin of the germ ; until they vanish from the homogeneous particle of matter, as the uni- form primordial state of every organism. Yet, even if our limited senses, with all the aids and appliances we can command, should fail at some stage to detect a difference of form or composition, we are not, however, entitled to conclude that there is absolute identity ; and, indeed, the specific relation between different germs and the media, or conditions indispensable for their vital preservation aud organical development, points to a more intimate, original, and permanent difference in the germs, corresponding to their re- spective parentage. But although man is so unlike, and in many respects so superior to all other animals, there is nothing in his frame that is not typified by creatures whose existence was long antecedent to his ; so that it may be truly said in this application, that all his members were written in the Book, when as yet there was none of them. What the final cause may be of this order and system of development, it is impossible for us to say. We are unable even fully to understand why the Omnipotent Creator should ever employ means towards an end, although we can see that those means, by their fitness and exquisite contrivance, may afford additional illustra- tions of His wisdom and benevolence, by furnishing to beings of the most exalted intelligence exhaustless subjects of contemplation and employ- ment for their highest faculties. The authors, however, are not always sufficiently careful to avoid relying upon unproved facts and uncertain arguments. They have been sometimes carried away by their prepossessions, in a way which not only offers to an opponent an almost irresistible temptation to seize upon one such instance as a specimen of all, but has a tendency to weaken the effect of the argu- ments which are borne out by proof, in the mind even of unprejudiced or- dinary readers. An instance of this precipitancy may be found at p. 65, where the names of Bemouilli, De l'Hopital, Leibnitz, and Newton are brought in to enhance the interest the reader is to take in the Cycloid, as the line of quickest descent of a falling body, — and then comes this state- ment, " Now, it is believed that it is by this very swoop that the eagle de- scends upon its prey. The question presses itself upon us. Who taught the birds of the air the line of swiftest descent, the discovery of which was believed to test the highest mathematical skill ?" But, may not the Atheist, who is more ready to discover the mote in his brother's eye than the beam in his own eye, demand why, or on what grounds, it is believed that the eagle desceuds in a cycloid ? If it is merely because that curve is the line TYPICAL FORMS AND SPECIAL ENDS. 15 of swiftest descent, — then the argument runs in a vicious circle ; — the de- scent in a cycloid is inferred from the wisdom of the Creator, and the wisdom of the Creator is inferred from the descent in the cycloid. That such actually is the process is obvious ; for who is able to tell the way of an eagle in the air ? How often has it happened that any person acquainted with the definition and properties, or even with the name, of a cycloid, has seen an eagle pounce upon its prey ; or who could pretend to trace with any degree of accuracy the curve that she described in that rapid swoop. More- over, even granting the fact, still the argument is unsound mathematically, for the cycloid is the line of swiftest descent only under conditions which never do attend the eagle's swoop, viz., that the motion should be through an unresisting medium, and that the accelerating force should be uniform, when resolved, in the same parallel direction. We wish the section on typical numbers had been omitted ; for the au- thors appear to have fallen into the very extravagancies against which they caution their readers, indulging in language incapable of any interpretation consistent with sober reason. After reproving the tendency of some com- mentators to suppose a magical power, or a mystical meaning, in numbers, they goon to say — p. 519, "The existence of this mystical tendency, in premature scientific speculations, should not lead us by an extreme reac- tion to affirm that numbers have no significancy in nature ; it should merely guard us from adopting them too readily — that is, it should pre- vent us from receiving them without inductive evidence, which is now, however, superabundant." And again, p. 520, — " Physical science shows that numbers have a significancy in every department in nature." They then give some examples, of which we shall reproduce a few, — " Six is the proportional number of carbon in chemistry, and 3 X 2 is a common number in the floral organs of monocotyledonous plants, such as the lilies of the field, which we are exhorted to consider." "Eight is the definite number in chemical composition for oxygen, the most universal element in nature, and is very common in the organs of sea-jellies." " In natural philosophy, the highest law, that of forces acting from a centre, proceeds ac- cording to the squares of numbers." Now, as regards this last assertion, it is not true that the law of gravity has any connexion with numbers, ex- cept so far as it is true that every possible proportion is capable of being at least approximately expressed by means of numbers ; and as to the coin- cidences, some of them almost ludicrous, which are adduced, what more do they amount to than this, that among a great multitude of phenomena, in- volving such small numbers, frequent repetitions of the same numbers occur 16 REVIEWS. of necessity. If those numbers have an intrinsic significance, surely we were entitled to expect some hint, at least, in explanation of the nature of that significance. We have then, page 521, a burst of declamation, — " He must be a bold man who will insist that should the God who fashioned nature be pleased to give to man a revelation of His will, in order to solve certain great problems started by the existence of sin in the world, He shall not be at liberty to make his dispensations of Providence and his institutions for in- struction and worship bear a certain relation to each other." No one is so bold as to make such an assertion ; but it does not require much boldness to assert that the authors have failed to produce the " superabundant in- ductive evidence to show that numbers have a significancy in nature" in any rational meaning we can put on the expression. We next meet with some remarks upon numbers mentioned in the Bible, p. 523. " Five is found in the pillars of the court of the temple, which were five cubits high, and five cubits apart ; and in the ten virgins, five of which were wise, and five foolish." " Twelve was the number of the sons of Joseph, of the tribes of God's people, and of the Apostles." "We read of seven x ten disciples ; Peter was exhorted to forgive his brother, not seven times, but seventy times seven, and the redeemed on Mount Zion are twelve X twelve thousand." After such instances of their " superabundant inductive evidence," come the following remarks, p. 525 — " We are not even inclined to look upon these recurrent numbers as implying any mysterious connection, as the so- phists have supposed, between objects which have the same number at- tached to them." " Nor are we to look upon biblical events as related, solely because they appear under the same number. It is possible, indeed, that the events may have a connexion in themselves, and have both ap- peared under the same number because of this connexion ; but the evidence of their relation must be sought otherwise than in their numerical corres- pondence. In vindicating the existence of these numerical relations we are thus, at the same time, laying an effectual arrest on the abuse of them." Putting together the above extracts, we are compelled to ask, what do the authors mean by the significance of numbers ? What proposition is it that they desire to prove by their examples of coincident numbers ? Do they vindicate thereby the existence of any numerical relation that has ever been doubted by any one ? In a work like that before us, which has to deal with facts not patent to the senses in their everyday use, and with propositions addressed to in- TYPICAL FORMS AND SPECIAL ENDS. 17 tellectual faculties which are brought but little into exercise, in the practical business of common life, it is, perhaps, impossible to avoid the use of some terms and phrases requiring explanation to the general reader. This is an inconvenience, which — as it cannot be entirely escaped — should be diminished as much as possible, by carefully considering, in each particular instance, whether the example, or the argument, that requires the intro- duction of such technical terms for its proper statement, is of intrinsic importance enough to counterbalance the objection to its use that arises out of the natural aversion of the reader to language presenting obvious difficulty, and — as it may appear to him — even studied obscurity. The authors have, as it seems to us, deviated from the discretion they ought to have exercised on this head — at one time giving abstruse definitions of terms, which they have no occasion for afterwards— at other times, in- troducing unusual terms, when their argument might have been stated just as well without them. The uninitiated would be apt to think that the structure of a bird's wing might have been shown to be adapted for flying, without such an array of learned words as in this paragraph (p. 207) : " It has been already mentioned, that the scapula and coracoid are, respec- tively, pleurapophysis and hasmapophysis of the occipital vertebra, and the clavicles or collar-bones, the haemapophysis of the atlas, or first cervical ver- tebra." How different a dialect this is from the style of Paley, for example, who never presents a difficulty unless to explain it, and rarely, indeed, em- ploys an unusual term where the sense could be given as well in words more simple. And, so far from losing in force by this condescension, the argu- ment acquires double credibility in his hands ; the easy flow of language, and the perspicuity of the phrase, being but the fitting counterparts of the judicious selection of the instances and the clear connection between all the links of the reasoning. Again, it appears to us that an insidious use is sometimes made — no doubt unconsciously — of those hard words out of the scientific vocabulary; — thus, pp. 435-6 : — " Final cause is, to say the least of it, as certain as unity of composition. It is surely as certain that the eye was made to see as that it is the homologue of the whisker of a cat. We give little credit for sincerity to those who acknowledge that they have overwhelming evi- dence in favour of the former truth, but no convincing proof in behalf of the latter." The intention of the authors would seem to require that the words " former" and " latter" should be transposed in the sentence — but let that pass. The argument itself seems to be a sophism depending upon the introduction of an unusual word " homologue" into one of the two D 18 REVIEWS. propositions which are compared together. The weight of evidence is thus made to tell, apparently, in favour of that proposition which will be most readily and most generally understood. But if we examine these two propositions abstractedly, the balance of proof, in reality, inclines the other way ; since the special use which any organ does actually serve, as part of a definite organism, constitutes but one Of the steps of that induc- tive process by the help of which we have to trace it through the mani- fold alterations of its accidental qualities, and consequent adaptation to other uses, in order to arrive at the demonstration of a constant relation to Final Cause subsisting in the indefinite variety of modifications of the functions, as well as of the texture, bulk, and form of the parts. In the passage we have quoted last, all that is denoted by the term " Homologue" is some coincidence in the use of the organs. We strongly suspect that the authors have taken their definitions of the terms from one source, and the propositions, in which the terms are involved, from some other authority that has put a very different meaning upon them, without themselves having detected the fallacy which they have thus been labouring to construct. That the human eye and the whisker of a cat are homo- logues is certainly not a Corollary from the definition of " Homologue" given in page 25 — " the same organ in different animals under every variety of form and function." The relation between the two, in this case, seems to amount at the utmost to an Analogy, according to the definition of an " Analogue," in the same page — " an organ in one animal having the same function as a different organ in a different animal." But much depends here upon the meaning of the word same, which appears to be applied, sometimes, to things totally different. Indeed, throughout the whole work we have to complain of a want of precision in the authors' reasoning. The design of the work is good, but in the execution of it they appear as if resolved to bring into play every particle of learning of which they were in possession, without much regard to its bearing upon the general argument. Their professed object was to prove and to illustrate the wisdom and intelligence of the Creator — first, by useful effects being produced by means so well adapted and so complicated, that they would not be attributed to chance on any of the acknowledged principles that regulate human belief; secondly, by such instances of order and method in the universe as may afford, by virtue of those same principles, a degree of probability, amounting almost to moral certainty, in favour of the supposition of Design. Now, under this second branch, it is plain that every instance of apparent order and coincidence, which does TYPICAL FORMS AND SPECIAL ENDS. 19 not arise from design, is actually hostile to their argument. The authors ought to have disposed of all such cases, by showing solid grounds of dis- tinction between the instances of agreement which prove design, and those which may exist without it. Instead of this course, required by fairness and true logic, they have adduced both classes of facts, without discrimina- tion ; and they content themselves with adding, in some few instances, a qua- lification to the effect that they do not rely on them as conclusive or strong examples. In conclusion, let us say, we shall be glad to see a second edition of this work, as well for the sake of its intrinsic merits, which are far from being inconsiderable, as on account of those defects which, by a little care, may be removed, but which at present impair, not a little, the force of the general argument which it was intended to develope. M. L. Elementary Course of Geology, Mineralogy, and Physical Geo- graphy. By Professor David T. Ansted, M.A., &c. Second Edition. London: Van Voorst, Paternoster Kow. 1856. This is the second edition of a Manual of Geological Science, which, on its first appearance, was very well received by Geological students. There was not much originality of thought or arrangement exhibited in it, but it was extensive in its scope, embracing Physical Geography, Mineralogy, Geology proper (or Descriptive), and the rudiments of Practical Geology. It was, moreover, brought out in a form and at a price suited to students, and as the compilation of its materials was generally well executed and mode- rately accurate, it was considered, on the whole, a good book. One of the highest testimonies to its practical value to the student is the fact, that it has been in use for some years as one of the text books in Geology for students in Experimental science in the University of Dublin. In the present edition the four-fold division of the subject is retained ; the Physical Geography is unaltered ; the Mineralogy somewhat modified ; the Geology recast as to its arrangement, not enlarged ; and the Practical Geology is doubled in extent and greatly improved. A considerable portion of the interval between the editions (six years) has been spent by Profes- sor Ansted in a professional way, as Consulting Mining engineer, and in connection with various mining companies ; occupations which have afforded him means of increasing his knowledge both of Mining operations and Mining terms. 20 REVIEWS. As we have not reviewed the first edition, our readers will readily excuse our entering in some detail upon the portions of this work which are un- altered, as well as upon the portions which are to be considered as addi- tions to the first edition. PHYSICAL GEOGRAPHY. The first two chapters of the Physical geography are occupied with an account of Chemical and Physical phenomena, which, in our opinion, ought to have been worked up with much more care, or altogether omitted. For example, in the table of Elements, page 9, there are many inaccuracies, several of which are chargeable on the author, and not to be transferred to the printer. We take, at random, Copper, Chrome, and Silver. Copper is said by Professor Ansted to occur ordinarily as Copper Pyrites, which is quite correct ; but he proceeds to add, that Copper Pyrites i3 formed of three atoms of copper and one of sulphur, which is completely erroneous. Chrome is described as commonly occurring in a compound of four atoms of protoxide of chrome, iron, magnesium, and alumina, known as Chrome iron ; a view which is not taken of that mineral by any mineralo- gist, as it is well known to have the same formula as Magnetic iron, with replacement of isomorphous elements. Again, Hornsilver is described as a bichloride of silver. We subjoin the correct formula for each of these cases : — PROFESSOR ANSTED. Malachite . . . . 2 Cu CO-f HO USUAL FORMULA. 3 CuO CO-4-HO 2 Copper Pyrites . . Cu S| 3 Cu S+Fe S 2 2 3 Chrome Iron . . CrO-f Fe O-p-Al 0-J~Mg 0 BO RO 2 3 Hornsilver . . AgCl 2 AgCl In the third chapter, which is one of the most valuable in the book, there are numerous tables of Areas of River Drainage, Relative areas of land and water, &c, &c, for which our author is principally indebted to John- ston's Physical Atlas. He has also introduced some of the newest information relative to these subjects from Lieutenant Maury's well-known work on the Physical Geo- graphy of the Sea. We extract the following relative to the Atlantic : — " The form and physical features of the ocean bottom of the Atlantic, between the northern part of South America and the latitude of London, are now known with sufficient accuracy to admit of general description. Down to latitude 15° north, and parallel to the European coast, is a large north and south tract from ELEMENTARY GEOLOGY, ETC. 21 2,000 to 3,000 fathoms deep, extending between the Canary Islands and the Azores ; while a broad belt of much higher level (nowhere deeper than 2,000 fathoms, and generally much less) and of a very irregular form, reaches to about 55° west. Beyond this a very deep and almost unfathomable region, everywhere more than 4,000 fathoms, and generally more than 5,000, extends east and west between 35° and 40° north latitude, and 45° to 65° west longitude. " The West India Islands are connected with the shallower bottom of 2,000 fathoms by soundings which nowhere exceed 3,000 fathoms, and in latitude 20° north and longitude 60° west the breadth of this shallower portion is sin- gularly narrow. Further south there is a belt of very deep water (more than 3,000 fathoms) nearly parallel to the South American coast, and much nearer the American than the African side. The steepness of the sea bottom is gene- rally much greater near the American coast, the depression being nearly 20,000 feet in 500 miles almost everywhere on that side, except near the Gulf of Mexico and the Caribbean Sea, in neither of which is there a depth of 1,000 fathoms in any part." — Page 28. The account of the Geological action of the Tidal wave, given in chapter TV., is one of the least satisfactory parts of the Physical geology of the book ; and we cannot help doubting whether Professor Ansted himself could explain clearly his meaning in the following sentence : — M The tide wave is probably a very effective force with reference to the sea bottom, and the transport of solid matter in deep water. Being a wave of the first order, its velocity is far greater in deep water than in shallow ; and, if it proceeded with uniformity and regularity, the velocity at a depth of one fathom being eight miles per hour, at the depth of 10 fathoms it would travel as much as 25 miles in the same time; at 50 fathoms, 57 miles ; at 100 fathoms, 80 miles, at 1,000 fathoms, 250 miles ; and at 4,000 fathoms, 500 miles."— Page 58. Does Professor Ansted mean to assert that the Tidal wave travels with such different velocities at different depths in the same sea ? If so, he has studied the theory of tides and waves to but little purpose. Or, does he imply, in this obscure passage, that the Tide wave is effective as a Geolo- gical agent, in proportion to its velocity ? If so, we fear he has confounded two totally distinct things — viz., the velocity of the Tide wave and the velocity of the particles composing it. It is on the latter alone that the Geological or Mechanical action of the tide, as a degrading and transporting agent, depends ; and not at all on the velocity of the tidal wave, which varies greatly, without any sensible alteration of the velocity of the indi- vidual particles of the water. It is scarcely possible to conceive that our author can mean that, in a sea of four miles deep, which is of common occur- rence, there are tidal currents at the bottom sweeping along at the rate of five hundred miles per hour ; and yet, it is difficult for a learner not to suppose that this is implied in the above sentence. MINERALOGY. Professor Ansted, in bis preface, states that he has " carefully modified the Mineralogy, retaining, however, in the main, the former method of 22 REVIEWS. arrangement, which he believes to be the one best adapted for the Geological student." With the arrangement of the Mineralogy we find no fault, as we believe it, although not strictly scientific, to be practically useful to the beginner. We could wish, however, that, in the modifications which the mineralogy has undergone, such errors as the following had not been care- fully reproduced in the second edition : — " Thus, for example, Calc Spar, in its purest form of Iceland Spar, is found to consist of Carbonic acid . . . 43*71) ,AAnn Lime .... 56-29X 100'00 > and if this is reduced to show the atomic relation, we shall find that the real proportion is two atoms of carbonic acid to one atom of lime, which represents the true nature of the mineral." — p. 157. We venture to assert that there is not a lime-burner in the country, who would not become conscious of the fact in a few hours, if Professor Ansted's description were to become true of Calc Spar. To show that the foregoing is fairly attributable to ignorance of Dufrenoy's meaning, from whom it is translated, and not to accident, we subjoin the following additional elucidation : — " In the case of Iceland spar, already mentioned, the mineral may be regarded as made up of two compound atoms of carbonic acid and one of lime — the com- pound atoms consisting in the one case of two atoms of oxygen and one of carbon, and in the other of one atom of oxygen and one of carbon:' — p. 159. A detailed blunder of this description is far more dangerous to the learner's progress than a simple mistake, as it produces upon his mind all the effect of a circumstantial falsehood, which is well known frequently to deceive even the expert. Such lamentable ignorance of the elements of Chemistry, would be very unpardonable in a teacher of Geology, were it not, unfortunately, very common ; and we mention this and similar cases which have occurred to us, on a hasty perusal of this book, simply to place the reader on his guard, not to take everything for granted which he may see in print, and not at all with any wish to detract from the real merits of the book, which we believe to be considerable. We go on to notice a few more errors in the Mineralogy, with the hope that they may be corrected in a new edition. In page 177, Meerschaum is described as an earthy and siliceous car- bonate of magnesia. It is an Hydrated silicate of Magnesia, and contains no carbonic acid. In page 217, Vitreous copper ore, or Redruthite, is described as Bisul- phuret of copper. This is not correct, and shows a want of knowledge of Chemical nomenclature. It is a Disulphuret of copper. ELEMENTARY GEOLOGY, ETC. 23 Page 219. The oxide of copper which enters into the composition of Azurite is called " oxide of copper, 70 per cent ;" while, in the same page, the oxide of copper entering into the composition of Malachite is described as " Deutoxide of copper, 70.5 per cent." We are at a loss to understand this difference in names, as the oxide is the same in both cases, viz. CuO. In page 223, the error respecting Hornsilver, already noticed, is re- peated, although the correct atomic weight of silver is given in the table? page 9. Mistakes of this kind arise from the indiscriminate copying by incompetent hands from the works of others, as this formula AgCl, 2 may be justified by writers who adopt 216 for the atomic weight of silver, which is double that used by Professor Ansted, viz., 108. By far the most serious difficulty to the student in this Mineralogy is likely to arise from the confused and sometimes inaccurate use by Professor Ansted of both the Chemical and Mineralogical formulae of Minerals. This, also, we suspect, arises from his having extracted his information from various sources, and transferred it quite undigested to the pages of his own book. In some instances, where we can recognise a literal translation, he has transferred errors and truth together, and given them equal pro- minence, to the serious detriment of his inexperienced readers. Notwithstanding the errors we have pointed out, we believe that the Phy- sical Geography and Mineralogy, although at present inferior, are capable, by a careful revision by a thoroughly competent hand, of being made equal to the rest of the book. Professor Ansted is evidently more familiar with Descriptive Geology and Mining operations practically than he is with the Mechanical considerations requisite in Physical Geology, and the Chemical knowledge, without which no real progress can be made in Mineralogy. We are of opinion that on a subject like Geology, of a practical charac- ter, no man can write well who does not himself possess a practical know- ledge of the particular branch he treats of; and hence, we believe, can be explained the unequal character of Professor Ansted's book. DESCRIPTIVE GEOLOGY. The statement of the preface that the Descriptive Geology has been " en- tirely re-arranged, and for the most part re-written" is only accurate when applied to the last three chapters of this part of the book, as the first three chapters are almost identical with those of the first edition. In fact, the original plan of the book, which tied down the author to write so as to suit second-hand illustrations borrowed from Beudant's " Cours Elementaire de Geologie," almost precluded the possibility of alteration or improve- 24 REVIEWS. ment in certain parts of the book. We cannot too earnestly or too frequently give our testimony against this growing vice : we do not think it is endurable, except in a translation ; and an author who condescends to write his text to suit his diagrams is not unlikely to borrow his ideas as well as hi3 woodcuts from others. By far the most valuable addition made to this part of the Descriptive Geology is the Table of extinct Genera founded on Mr. Morris' valuable Catalogue of British Fossils. In the last three chapters of the Descriptive Geology, Professor Ansted has adopted the Natural method, viz., proceeding from the oldest epochs to the newest ; for, notwithstanding the high authority of Sir Charles Lyell in favour of the opposite course, we consider that Geology, which is the History of the Earth, should be treated like other Histories, and commence with its period of Myths and Fables, its nebular Hypothesis, and Cosmogony, its Azoic Rocks and Crystalline schists, before it enters upon the beaten path of the Secondary and Tertiary Epochs. What should we think of a History of England which commenced with the reign of Queen Victoria and in which we could not read of the good Canute sitting on the shore of the sea in his own chair until we reached the last chapter. Of this interesting, because unknown, epoch of the Azoic and immedi- ately subsequent rocks, he writes as follows : M 603. Rocks called by Sir R. Murchison and others azoic, as not at present yielding any evidence of life at the time of their formation, are found in Wales occupyhg an intermediate position between crystalline and fossiliferous rocks. These lowest rocks include the Harlech grits and Llanberis slates. They are re- presented in Iteland (on the coast opposite the Isle of Ansjlesea) by similar rocks, in which remains of two species of zoophytes are found. These are hoth referred to the same genus {Oldhamia), and at present th< y are the most ancient forms of organisation that have been determined. 'J he rocks consist of contorted schists, of the kind called by German Geologists grauwacke (anglicised into greywache), fine and coarse grits and fine purple roofing-slates, largely worked in North Wales, altered in places into chloritic and mica schist, and in others into quartz rock. The pre- existing masses out of whose materials these beds were formed have not yet been found in the British Islands, although in Bohemia and in North America there are crystalline rocks, which, from their underlying position, are known to be of still higher antiquity. The thickness of the oldest mechanical rocks in Wales (the Harlech and Llanberis series) is estimated at 1,500 feet. 41 604. Next in order, and also exhibited in Wales, are the Lingula flags (about 2,000 leet thick, containing peculiar fot-sils, and consisting chiefly of gritstones and schists with imperfect slaty cleavage passing into the sandstones and fine quartz rock of the Stiper stones in Shropshire. Above these are the Tremadoc states (1000 feet), and above these again the Arenig slates and Arenig porphyries (7,000 leet). In all this great thickness the fossils hitherto found are very sparingly distributed, and the number of species is very small, but a difference is recognised between these species and those of overlying rocks. The Lingula (a small bivalve shell) is the most common fossil ; but there are also two small trilobites, a shrimp-like crusta- cean, and a zoophyte. ELEMENTARY GEOLOGY. 25 <; The bed3 above described are sometimes called Cambrian, but, as already ex- plained, it is difficult to separate them with propriety from the Silurian series'.'' In the Journal of the Geological Society of Dublin, which is printed in the present number of the Natural History Review, is a paper by J. R. Kinahan, Esq., M.B., announcing the addition of a fresh and interesting group of animals to the solitary Oldhamias of Bray Head ; we take this opportunity of directing our readers' attention to it, as we believe it to be a valuable addition to the scanty knowledge we possess of the Organisms of the Cambrian Epoch. An interesting question is alluded to in the closing paragraph of section (603), already quoted ; viz., where are the original rocks whose wear and tear supplied the materials for the vast thicknesses of beds deposited during the early (Silurian Epoch ? In connexion with this inquiry, we subjoin the following passage : — " 609. Commencing with the crystalline and altered slates of Cumberland, North Wales, Scotland, and Ireland, it may be observed that the proportion of argillaceous matter and quartz is much greater, and the mixture with calcareous rocks less, than in strata of more recent date. Although of a thickness amounting to many thousand feet, the sedimentary deposits forming the base of the Silurian system are, almost without exception, composed of clay, pebbles, or boulders, and siliceous sand ; while the frequent presence of mica seems to indicate a preponder- ance of granitic rocks amongst those to whose degradation and disintegration this long series of crystalline slates, mica-schists, micaceous sandstones, conglomerates, imperfect and highly altered limestones, and quartz rock must be owing. " The unvaried character of these beds over large tracts of country, and the general resemblance among the oldest sedimentary deposits, have been looked upon as a strong argument in favour of the uniformity of the materials of which the original framework of the solid surface of the globe was composed.'' The theory of " Contemporaneous Traps" now generally adopted would suggest a source from which part, at least, of those vast deposits might be derived ; but the greater portion of them must have had their origin in the Mechanical degradation of pre-existing rocks. Where and what are these rocks ? We feel disposed to agree with Prof. Ansted as to the large quantity of Mica in the Silurian Slates, as such a quantity of Mica must be accompanied with a corresponding proportion, more than one- tenth, of alkalies (potash) ; and such an amount of alkalies is usually found to exist in ordinary slates. It is, however, a subject not sufficiently examined, and well worthy of attention. And it is worthy of considera- tion whether the Mica in the more crystalline of the Azoic rocks be not due to metamorphic action, and not to the degradation of granitic rocks. Be this as it may, the fact is certain that in Great Britain and Ireland we do not see the primitive rocks whose weargand tear supplied the elements of the slates of Wales, Cornwall, Cumberland, Down, Armagh, and Kildaf e. 26 KE VIEWS. The granite of Cornwall is of carboniferous date in all probability ; the granite of Leiuster is post-silurian, although ante-carboniferous ; the gra- nite of Down is post-carboniferous ; and that of Donegal is, probably, also carboniferous, or only somewhat antecedent in age. Where, then, are the presilurian Granites which supplied the materials of the thick masses of slate we have mentioned ? Ordinary Granites consist of about 25 per cent, of Quartz, 60 per cent, of Felspar, and 15 per cent, of Mica. When such a rock is exposed to the action of water and converted into a stratified rock, its felspar loses its alkalies, while the mica remains nearly unaltered, and the resulting rock will be a compound of Impure Kaolin, Quartz, and Mica, mixed in proportions not absolutely fixed, but, probably, never very far from the following: Quartz 25 per cent., Kaolin 18 per cent., and Mica 57 percent. Another circumstance which characterises the early Silurian slates is the small proportion of lime and magnesia found in them ; this falls in well with the supposition of their being derived altogether from Granitic Rocks. It is certainly a curious fact that the quantity of lime in the crust of the earth increased with the increase of organic life, and, also, probably, the quantity of soda and phosphorus — as if some change of mineral conditions of the surface of the globe had rendered it more fit for the habitation of or- ganised beings. We must, however, return from this digression to Prof. Ansted's book. One of the most interesting parts of the fifteenth chapter is the description of the Oolitic coal fields, including the remarkable beds of India, pp. 375-380. From the specimens of fossil plants recently sent from the Rajmahal Hills, there can be little doubt of their being more closely allied to the Oolitic coal plants of Scarborough than to the vegetation of the true carboniferous epoch. The Palaeontological portion of the book is respectable ; the text written to suit the woodcuts, as before ; but there is nothing in it which calls for special praise or mention. PRACTICAL GEOLOGY. We regard this portion of the book as the best written and most useful Manual of Mining with which we are acquainted, in the English language; and we think that it supplies a valuable aid to the student of Mining Engi- neering. It is fairly entitled to be considered as a new addition to the former edition of this book, as it is doubled in extent, consisting of one hundred and twenty-three pages, instead of sixty-one, and the whole is carefully arranged for the use of students. S. H. 27 Retrospect of various works published during the last Year, New editions, and New works in progress. The demands of a still increasing number of Zoological, Botanical, and Geological communications, in the pages of various foreign Serials, which call for our notice, as they are more liable there to lie hidden from the knowledge of British Naturalists, than the more considerable and indepen- dent works of Natural History, that issue from the press at home or in other countries, have circumscribed the space we could afford to reviews of the latter class of works, and limited the number of our articles in this de- partment. In compensation, we propose now, at the commencement of a new year, to indulge ourselves in a lightly skimming retrospect of the scientific literature of the year 1856, as it bears upon the study of the native Fauna and Flora in particular. But even here, we are obliged to set certain bounds to ourselves ; so, passing by various splendid illustrated works in progress, and many of another sort, devoted to the Vertebrata and Mollusca, as well as those upon General Botany and Paleontology, we will descend at once to the Articulata, and commence with the different orders of Insects. I. Diptera. We have elsewhere inserted a critique of Mr. Walker's vo- lumes, intended to serve for a British Fauna of this order, the last of which was published the beginning of the year. The same indefatigable hand has brought out the concluding part of the Diptera Saundersiana also, in the course of the same year, while two other articles, also by him, in the Journal of the Linnean Society, from materials supplied by the same rich collection, make known fresh harvests of Mr. Wallace's gathering on the virgin soil of Malacca and Borneo, and afford a proof what unexplored treasures are yet in keeping for the students of this order, when voyagers and travellers shall have better learned not to overlook so much the less obtrusive and more fragile races of flying insects, for the gaudier charms of the beetles and the butterflies. It is not long since we gave, in this Jour- nal, an article on Recent Works upon the Diptera of Northern Europe, and we expect it will not be very long before a like call is made upon us in the name of those of Southern Europe. The lists of Austrian Diptera by Dr. Schiner, on which Dr. Loew has expressed such a favourable judgment (seethe Volume for 1856, page 92), are proceeding through the different families in succession, and we have lately received, besides, a small volume by Prof. Rondani of Parma, the welcome forerunner of a general work 28 REVIEWS. which he has undertaken on the Diptera of Italy, from which country many interesting accessions to the European Fauna of this order may rea- sonably be looked for. II. Lepidoptera. The most interesting intelligence we have in the Bibliography of this order is the completion of Dr. Herrich-Schaeffer's great and sumptuous work. Prof. Frey of Zurich has produced a modest and meritorious volume on the Tinese and Pterophori of Switzerland, which will be useful to the British " Tiuearist" also, though possessed already, as we may assume him to be, of Mr. Stainton's volume on the British Tineina. Of the last-named author's polyglott Natural History of this tribe, sufficient materials have not yet accrued, as it seems, for the publication of another of the annual volumes. The Manual of British Butterflies and Moths also is to take a deliberate nap at the end of the Noctuina and the beginning of the year, while awaiting the appearance of Guenee's work on that group, shortly to be forthcoming in Roret's " Suites a Buffon." III. Hymenoptera. Dr. Nylander has given a Monograph of the For- micidaa of France, in the " Annales des Sciences Naturelles," wherein he has reduced again several of the new genera, which Mayr had dismembered from Myrmica, chiefly by distinctions drawn from the varying number of joints of the palpi. From Ruthe we have the promise of a Monograph of the Braconidae of Germany, which is likely to be valuable, both from his copious materials and the minute accuracy of his investigation, judging by the specimen he has given in the groupe of Microctoni. At home, we have no important accession to the literature of this order, except the British Museum Catalogue of British Ichneumonidae, by Mr. Desvignes. We have not yet had the opportunity of examining it, but we feel assured before- beforehand of its utility, from the author's thorough knowledge of his subject. IV. Coleoptera. If for a republication of a standard work of Entomology generally, Kirby and Spence's Introduction is the best value for the lowest price we know ; so are Lacordaire's volumes on the Genera of Coleoptera the cheapest of an original work. Estimated by the labour and materials they must have required, the information condensed in them, and the time and pains which they save the student, were it only as an index to the species, they would be worth their weight in silver at least. The third volume, containing the genera of the Pectinicornia and Lamellicornia, has appeared, and we have reason to hope that the fourth will speedily follow. To all the students of this order among ourselves, a long-desired and very welcome acquisition is the first part of a revised list of the Rhyn- chophorous beetles of Britain, Bruchidae — Curculionidse, by Mr. Walton, WOKKS ON BRITISH COLEOPTERA. 29 lately published as another of the Blue books of the British Museum. We have noticed, also, with much satisfaction, the Monograph of the European species of Catops, by Mr. Murray, in the Annals of Natural History, illus- trated with many wood-cuts, exhibiting the minutiae of sculpture, the mi- croscopical investigation of which he has here applied to the discrimination of the species of this rather perplexing group, and has carried it out to a degree of refinement hitherto unattempted for the purposes of Descriptive Entomology. Although no independent work, of any extent, on this order has issued from the press in Britain, during the past year, yet the Ento- mologists' Annual, continued for 1857 by the enterprising and persevering editor, bears witness that the study of the indigenous species has been pursued with commendable zeal, the additions to the British Fauna in this order, for the year 1856, amounting to not less than sixty species, two of which, however, are stigmatised with a note of suspicion, as possible " importations." Mr. Stainton informs us — and who should be better authority than the Editor of the " Entomologist's Intelligencer" — that there is at present a cry out for a " Manual of British Beetles." How much this clever writer himself, and his "Manual of British Butterflies and Moths," may have had to do with exposing the want, and suggesting the feasibility, of such an undertaking, and thus evoking that importunate voice which pursues him, as he confesses, even to the shades of Lewisham, it is not necessary now to inquire. We should be sorry if we were — most erroneously — accounted unfavourable to anything tending to make the science more popular, and to aid the amateur collector in giving to his gatherings both a local habita- tion and a name. On this head we are quite at one with our valued con- tributor, Dr. Loew, whose remarks the reader will find in the volume for 1856; see page 68, and elsewhere in the same article. Still, we would venture to deprecate anything like a hasty compilation of the sort referred to, got up merely to meet the supposed demand. It is not unnatural to conjecture that such a Manual would probably be framed on the model of Mr. Stainton's popular monthly issue for the benefit of the Butterfly-collec- tors. Now, although the Lepidopterist of to-day is scientifically much in advance of the "Aurelian" of the last generation, still the study of the Co- leoptera has kept its vantage-ground in the literature of Entomology ; and it demands to be treated accordingly. A writer on British Coleoptera, who, confining himself to his local materials, should at the same time indulge in changes of the system and nomenclature, in accordance with his private views, as to parts of his subject which he had perhaps studied almost for 30 REVIEWS. the first time, when he thought of setting about to teach others ; views which — however original and just they might be — the concise and popular treatment of the subject, imposed on him by the form of his work, would not allow him to prop up with that copious array of exposition, illustration, and definition, which is requisite for the introduction of new aphorisms, — a writer, we say, in such a case, would be too apt only to embarrass that class of readers on whom he calculates, and would certainly do much less to promote the study of the science, than if he had contented himself with adopting some approved arrangement of the European Coleoptera, and giving so much of the distinctive characters, in the analytic form, — or any other that he might consider more suitable, — as would give a clue to the received names of the species and their position in a more general system. If, on the other hand, the intending author of a Manual of British Beetles should conscientiously purpose to acquire — if he do not possess it already — that thorough knowledge of the classification and specific distinctions, of which he has to give the practical results in a brief and familiar form, suitable to the wants of the numerous body of collectors, who have little time for study, and little mastery of the minuter technicalities of Zoological science,— it may be questionable whether the time is indeed yet come for attempting a work of such large scientific exigency, on the basis of a limited Fauna like that of Britain, while important new works, destined to do a like ser- vice for the more copious Fauna of Continental Europe, are in progress, and yet far from their completion. For our own part, as mere amateurs in the matter of the native Coleoptera, we are disposed, for the time being, to rest content with Stephens' Manual, and that gradual revision of it, which the families are undergoing in succession, at the hands of Messrs. Walton, Dawson, and Clark, Waterhouse and Jansen, Murray, Wollaston, and others. To those who desire a more comprehensive book of reference — if they can read German with any degree of facility, we would recommend Redten- bacher's Fauna Austriaca, as a very useful guide ; the intrinsic scientific merits and originality of which have perhaps hardly received their due meed of acknowledgment, in consequence of the professedly popular purpose for which it was composed, and which it has so well answered. We are happy to hear that a New edition is about to appear, in which, besides numerous additions to the list of the proper Austrian species, those of the rest of Germany — which in the first edition were huddled apart into an Appendix — will be embodied in the general analytical tables of the text. A work which promises to become still more useful to the British Cole- FRENCH FAUNA, COLEOPTERA. 81 opterist — -first, as it is not so strictly confined to the dichotomous method, with its, apparently inevitable, occasional ambiguities ; — secondly, because the territory of the Fauna agrees with Britain better, in Geographical meridian and Hydrographic circumstances, — is the " Faune Entomologique Francaise, Coleopteres, par MM. Fairmaire et Laboulbene," of which we have lately received the third part, completing the first volume of 665 pages, 12mo., giving brief but clear characters of two thousand and forty French species, besides many indigenous in the neighbouring countries — Britain among the rest — which are considered not unlikely yet to be found in France ; the whole arranged under convenient sections descending from genus to species, and illustrated with ample data, in the most concise form, respecting the local distribution within those limits. As a matter of course, this work comprehends a far greater multitude of species than are known in the British islands, and among them many southern types, not to be looked for here at any time. But of the actually known British species, there appear to be comparatively few not included in it. A general colla- tion of the work — so far as it has been carried — with Stephens' Manual of British Beetles — or, indeed, with any other complete list of the indigenous species of this order, which we possess as yet — would lead to a very erroneous estimate of the proportion. We have confined ourselves to the comparison of a single family, one of the most extensive and most thoroughly investigated, and which, of all the great families of the order, has been earliest made the subject of a complete revision, subsequent to the date of Stephens' Manual. Of the two hundred and ninety- two indigenous species of Geodephaga given in Dawson's Manual, we find but twenty which are not described in the Faune Francaise ; and these are mostly of very limited local range, or extreme rarity ; one-third of the number being species first and recently characterised by Mr. Dawson himself, all of which, perhaps, can scarcely be considered as yet sufficiently " ventilated." We apprehend, too, that the number not in common to both will be yet further diminished by the sup- plemental additions promised ; and the authors seem disposed, as they advance, to be more liberal in the indication of the probable natives of France, so that the proportion of deficiencies is not likely to be increased, at least, in the families to follow. The first volume of this Fauna of France, now published complete at fifteen shillings, has those two thousand and forty species, distributed under the following families: Cicindelidse 12 species, Carabidae 590, Dytiscidse 149, Gyrinidae 10, Hydrophilida* 88, Histridas 94, Silphidas 113, Trichop- 32 REVIEWS. teiygiche 34, Scaphididae 5, Scydmaenidae 31, Pselaphidae 47, and Staphy- linidae 867 species, besides those introduced incidentally, in the manner aforesaid. The authors have been in correspondence with their fellow- labourers, — the continuators of Erichson's Insect Fauna of Germany, which we have to notice also presently ; — and, accordingly, the new groups, therein proposed by Kraatz, for the better determination of the difficult tribe of Aleocharini, are not left undistinguished in the French text. The most accurate determination of the species, and of the trivial names according to their legitimate priority, has been taken from the recent mono- graphers who have treated particular families most carefully in these respects. Where such help has been wanting, the authors do not seem, indeed, to have used as much diligence or judgment in their more extensive work as Mr. Dawson has done in his Monograph, in regard to the latter point at least ; but as they have ventured to exert less original decision, so they have laid themselves less open, perhaps, to common-place adverse criticism. It ap- pears that they recognize in general sound principles of scientific nomen- clature and chronological precedency, but they have by no means invaria- bly adhered to these in practice. We are not prepared, indeed, to blame them for having retained — whe- ther deliberately or from mere traditional habit — the modern trivial names of many species, to the exclusion of the more ancient, but now unfamiliar ones of the last century ; as for example — Carabus monilis (catenulatus Scop.) ; C. catenulatus (purpurascens Payk.) ; Loricera pilicornis (caerules- cens Linn.) ; Chlaenius holosericeus (tristis Schaller) ; Feronia striola (atra Vill.) ; Anchomenus prasinus (dorsalis Bruennich) ; Trechus paludosus (rubens Fabr.) ; Bembidium guttula (riparium PayJc.) ; Noterus crassi- cornis (clavicornis Deg.) ; Hydroporus pictus (punctulatus Mueller) ; H. lineatus (velox Mueller), and several others ; where our own inclination would have been to restore the ancient names, which are assignable without any reasonable doubt in most of these cases. A point at which they have laid themselves more open to criticism is, that for want of antiquarian re- search, they have adopted some changes of the commonly received nomen- clature, which do not yet attain to the ultimate Q. E. I. of the very ear- liest scientific nomenclature. In such cases they must be judged to have parted with a confessed advantage, for the sake of a supposed greater, but eventually an illusory gain. We take for an instance Carabus angusticollis JP6., reduced to assimilis Ph., the earlier of these two names undoubtedly, but Scopoli had described the species long before, and characteristically, as C. junceus. Micralymma johnstonse Wwd., the typical name, has fallen FRENCH FAUNA, COLEOPTERA. 33 a sacrifice to its identity with Omalium brevipenne Gyll. ; here the authors should have gone back further still, to recognize in this species the Staphy- linus marinus Strosm. Arpedium humile, of Erichson's classical, work on the Staphylini, appears here — upon what principle we can hardly guess — under the more recent trivial name of myops Hal. ; but it has escaped them that this insect, so common on Ulex wherever the plant grows, was first described by Stephens, as Omalium subpubescens. We observe that Mr. Jacquelin-Duval, the pains-taking monographer of the Bembidia of Europe, has been rather severe on both Mr. Dawson and the authors of the Faune Francaise ; because they have chosen to de- part from his conclusions in some cases, without having had as copious materials as he at their disposal. The critic seems to have taken his objects clearly at a disadvantage on one or two points ; but we protest against the general spirit of his attack, which goes to confound credibility of testimony and infallibility of judgment, treating a difference of opinion as little short of a personal affront. While we desire to introduce the Faune Francaise to English Entomolo- gists, who want to name their collections of Coleoptera on some authority better accommodated to the actual progress of the science than we can aver Stephens' Manual now to be ; we must not pass over, without notice, one inconvenience in the use of it, resulting from the want of an index of the species to the first volume. It is, no doubt, intended to give a ge- neral index at the end of the complete work ; but that may be rather long to wait for such an almost necessary save-time. The authors seem already to have discovered that the pace at which they originally proposed to bring out the parts was impracticable, having regard to the proper preparation of the matter. The first part came out in 1854 ; the third, which com- pletes the volume, has not been very many weeks in our hands : never- theless, the several Parts, as well as the title-page of the Volume, bear the date 1854. This " dies praepostera" is a petty artifice, which we regret to see sometimes practised by the French authors and publishers in particular, " pour prendre date." We would, with all becoming diffidence, venture to recommend for imitation the conscientious practice of some other writers — J. Curtis for example — who have attached the date of actual publication, not only year and month, but the precise day of the month, to every single plate which came out in periodical parts. Later in its commencement than the Faune Francaise, but of much deeper scientific import, and more comprehensive in its scope, is the continua- tion of Erichson's Insekten Deutschlands, undertaken by Dr. Schaum 34 REVIEWS. aud Messrs. Von Kiesenwetter and Kraata, all of them already favourably known by various contributions to the history of this order, or to systematic Entomology. The division of labour in this case gives hopes that we may see the accomplishment — neither hurried up at last, nor degenerate from its origin — even of an undertaking under which the delicate health of the lamented Erichson early succumbed. The three parts before us are Part I. of Vol. I., the commencement of the Carabidae, by Dr. Schaum, and Parts I. and II. of Vol. II., by Kraatz, embracing the Aleocharini. The genera of this tribe are separated by such subtle characters, that the student may find himself sometimes compelled to renounce the direct in- vestigation according to the method of Erichson's excellent Monograph, and to betake himself to an empirical comparison of several alternatives, in or- der to arrive approximatively at the place of the species he is investigating ; uuless he can spare the time, and has also acquired the manual dexterity, necessary for a satisfactory microscopical investigation of the oral organs. Accepting, as we feel obliged to do, this difficulty as inseparable from the great multiplicity and close affinity of the forms, the inconspicuous size and little variety of secondary qualities, among the Aleocharini in particular, we cannot deny to Kraatz praise for having availed himself, to the utmost, of this imperative though difficult branch of investigation, for the better de- finition of the genera, and the separation from them of sundry discordant species. He has here subdivided the Aleocharini into three sections — I. Genuini or Brachypalpi ; II. Gyrophamini ; III. Gymnusini. Under the first of these, the following new genera are characterized — Stenusa type Silusa rubra Er. ; Stenoglossa, type Homalota semirufa Er. ; Ischno- glossa, including Aleochara prolixa Gr., &c. ; Leptusa, for species of Oxy- poda and Homalota of authors, as Aleochara analis Gyll., Homalota piceata Muls. &c. ; Thiasophila, Aleochara angulata Er., &c; Hom,oeusa, Euryusa acuminata Masrkel ; Haploglossa, Aleochara pulla Gyll., &c. ; Dasyglossa, Oxypoda prospera Er. ; Hygropora, Ox. cunctans Er. ; Ilyobates, Al. nigri- collis Gr., &c. ; (the g. Callicerus Gr. is restored) ; Chilopora, Calodera longi- tarsis Er., &c. ; Ocyusa, Oxypoda maura Er. ; Phlceodroma, anew species ; Tomoglossa, Homalota luteicornis Er. ; Schistoglossa, Horn, viduata Er. Of the Gyrophamini, Gyrophama lsevicollis of the Author now constitutes for him a new genus Agaricochara. Lest any one should fancy that a multipli- cation of genera so considerable as this may have left none of the old ones of comfortable amplitude, we may refer to the genus Homalota, as it stands here, with a hundred and forty-two species left for Germany alone. Possi- bly the propensity of the author may be rather towards the separation of INSECTS OF GERMANY, COLEOPTERA. 35 species on slight characters. We observe that he adheres to his previous opinion that the Phytosus nigriventris is a distinct species, and not the other sex of Ph. spinifer, as English authors have considered it ; — and on this head we have no decisive observations wherewith to oppose him. Again, he characterises the Aleochara obscurella of Thomson, from the Swe- dish coast, as a distinct species, by the name of Al. grisea. The distinctions he has assigned are so minute, and most of them merely comparative, that we scarcely venture to pronounce confidently that the common species of the British coasts represents this Al. grisea, as is most probable. If Kraatz is right in separating them as species, the Al. obscurella of the Faune Fran- caise is probably identical with the British and Swedish species. Kraatz again seems to imagine that the sexual difference of size may indicate yet another species to be separated from Al. obscurella. We suspect that the authors of the Faune Francaise have been led, in the like manner, to mul- tiply species unnecessarily in some instances ; — thus the characters given of Diglossa submarina seem rather unsatisfactory, and some of the suppo- sed differences between this and D. mersa are confessedly inconstant. Dr. Schaum in his descriptions of Carabida?, in the part before us, has expatiated on the subject of varieties to such a degree as threatens to make the first a very ponderous volume, if he goes on as he has begun here. It must be confessed, however, that the treatment of the nominal species of this great genus, previously, had been such as to leave much rubbish for the critic to clear away. Forty-eight pages of this part are devoted to the characteristic of the thirty species of Carabus, which are admitted as genuine species, and natives of Germany. More valuable yet, in our eyes, than these special details, however elaborate, are the learned author's generalities on the families and on the classification of the order. Commencing with the carnivorous beetles, he has reverted to an older view than that now generally received, in excluding the family Gyrinidse from the united group of land and water carnivorous beetles, the Ade- phaga of Clairville. Of Kiesenwetter's share of the undertaking no part has yet appeared. It would be hard to overrate the prospective utility of this work to the scientific Entomologist ; and we heartily wish it a steady and uninter- rupted progress, and an increasing number of readers. For the conve- nience of the mere British collector, the Faune Francaise will, probably, be found the more suitable, as.it will certainly be far the most portable, if both works are continued on the scale commenced respectively. We can scarcely wish it were otherwise, as there is occasion for both of these 80 REVIEWS. attempts to supply much-felt existing deficiencies ; and while each is par- ticularly accommodated to its own circle of readers, they may both be serviceable to «//, as mutually supplementary. We reserve for a future occasion a more particular critical examination of them, when further ad- vanced towards their completion respectively : our object now has been only, or chiefly, to bring them under the notice of British Entomologists, who are discontented with the home-made provision for the wants of the Beetle-collector, and desirous of some stronger food to promote scientific growth. While they are only in progress, we recommend, for present use, Redtenbacher's book, as already complete in its own sphere of investiga- tion, and as approved by our private experience, in its application as a guide to the correct and easy determination of the great majority of the British beetles also. V. Neuroptera. There has been a lull, as if of exhaustion, in this order, since the appearance of Fischer's excellent Monograph of the Euro- pean Orthoptera ; Fieber having only followed in the wake of that, and Von Brauer's investigations being concerned with Physiology more than Taxiology. The Entomologist's Annual, again, furnishes British collectors with a popular description of the native Libellulidae by a master in the science, Dr. Hagen. Mr. Stainton deserves their best thanks for the effec- tive aid he has enlisted on behalf of British Entomology ; and we hope to see many more such contributions introduced to home readers, through his intervention. VI. Hemiptera. The system of Heteroptera, in the completed work of Hahn and Henrich-Schseffer, has been receiving large additions, both in genera and species, at the hands of Staal, chiefly from the materials collected by Wahlberg in Caffraria. Kirschbaum has added materially to the European species of Capsus, &c, in his list of the Capsini of Wiesbaden. The illustrated Monograph of Aphides, by Koch, seems to have come to a stand still. We have been looking out in vain, also, for the promised volume on the British Hemiptera, by Mr. Dallas, which was to have pre- ceded the concluding volume of the Diptera, in the series of "Insecta Britannica." Although Mr. Walker's volume is out, and Mr. Dallas makes no sign, we hope the other is not superseded, but only lying by awhile, to ripen more completely. In general Entomology, probably the most important production of the past year has been the Seventh edition of Kirby and Spence's Introduction, which we reviewed at the time of its appearance ; while the most novel, undoubtedly, is a weekly newspaper for Entomologists, which, we perceive, MISCELLANEOUS NOTICES. 37 the spirited editor proposes to continue, during the next season also, in spite of the loss incurred on a weekly penny paper addressed to a reading public so limited. We understand that Mr. Curtis is occupied in preparing a new collected edition of his Reports on Insects noxious to Agriculture, originally con- tributed to the Journal of the Royal Agricultural Society. It is a subject of congratulation that these valuable papers will thus be rescued from the comparative oblivion in which they were buried there, in consequence of the very limited interchange of their respective knowledge which takes place, as yet, between the Farmer and the Naturalist. It is an exemplifi- cation of this, that Noerdlinger, in his new and pretty copious work on the " Little Enemies of Agriculture," has not derived any of the materials from the numerous essays in English on this subject to be found in the above- named Journal and in the Gardener's Chronicle. Zoologie Agricole, par E. Blanchard, which includes the insects noxious to the crops, has been continued in monthly parts. In Insect Physiology we have a paper on the Respiration of Insects, by Mr. Lubbock, in the Entomologist's Annual, professedly popular rather than profound ; an interesting communication, by M. Hicks, in the Journal of the Linnean Society, on a peculiar structure observed in the Halteres of the Diptera, which, on this ground, he concludes to be organs of sense, — as also certain parts at the base of the wings of insects in general, wherein a similar structure may be traced. The latest number of Siebold's Journal of Scientific Zoology contains some valuable observations by Stempler on the development of the Scales of the wings and other parts, in the Lepidop- tera, establishing more particularly than had been done before the perfect analogy, in origin and growth, between this kind of covering and the more usual form of the hairs of the Articulata ; which latter type has been in- vestigated morphologically by Menzel, in a paper in the Stettin Ento- mological Journal of 1856, as well as in some previous separate publica- tions. Crustacea. Several important additions to the Literature of the Class have appeared during the past year ; chiefly in Wiegmann's Archives of Natural History, and the Proceedings of the Swedish Academy of Science, and of the Danish Royal Society. On the Entomostraca we have a paper by Mr. Lubbock in the Transactions of the Entomological Society of London, and another by Fischer in the Transactions of the Bavarian Academy, both illustrated with numerous figures. Arachnida. An essay on the Cheraetida3 (Pseudoscorpii,) by Dr. 38 REVIEWS. Menge, in the Transactions of the Natural History Society of Dantzig, is noticed elsewhere, in the Reviews of Foreign Serials. Annelida. The Embryology and Alternate generations of the Intestinal worms have been yet further elucidated in various quarters, chiefly by Siebold, Kuechenmeister, Leuckart, Beneden, and Philippi. An interesting popular sketch of the recent discoveries in this province of Natural History, which have excited such a lively interest, has also been given by Mr. De Quatrefages, in the Revue des Deux Mondes. The Prize in Physical Science, which was offered for the best account of the structure and develop- ment of the common Earthworm, having been awarded to Mr. Udekem, his essay has been included in the publications of the Belgian Academy. Protozoa, etc. The phenomenon of Encystment has been demonstrated, in some additional instances, among the Infusoria. For a valuable contri- bution to the Natural History of Spongilla we must refer the reader to the original paper by Lieberkuehn, in Mueller's Archives of Anatomy, which we have noticed elsewhere, among the Foreign Serials. A translation into English, from the German edition, of Van den Hoeven's Manual of Zoology, by W. Clark, and also one by Dr. Knox, of Milne-Edwards' Elementary Course of Zoology, from the latest French edition, have recently appeared. Of the two volumes which compose the former work only one has yet come out in the English, embellished with the same plates as the German edition, and costing, singly, as much as the latter does complete. Milne-Edwards' admirable text-book is now, for the first time, given, in an English dress, in its integrity — even the most glar- ing blunder of an unlearned compositor being faithfully reproduced ; — but it has long been familiar to us, in substance, through the medium of extracts copied into other popular works — openly, and with- due acknowledgment, on the part of some authors ; — in other cases clandestinely, to deck some Jackdaw of science with the borrowed plumes of an unearned reputation. More important, than either of those two translations, for the promotion of scientific Zoology among English scholars, is that of Siebold's Comparative Anatomy of Invertebrate Animals, by the late Dr. Waldo Burnett, which we have received from the other side of the Atlantic. The publication there of a work so purely scientific, and of which no version has been adventured in England, is but one of many proofs of the deep hold which the Natural Sciences are taking in North America, even side by side with the fierce excitement of gold-winning in some of the newly settled States A new and enlarged edition of the original work, in German, is also com- menced ; but the appearance of the volume of Invert ebrata, by Siebold, COMPARATIVE ANATOMY. 39 has been hitherto delayed, while two parts of the Vertebrata, by his coad- jutor, Stannius, have come out already. Of another important work, and this a new one, on Zoological structure and classification — " Zoonomic Letters," by Dr. H. Burmeister — the first volume, commencing with the lowest forms of Animal life, has reached us ; but this work will require a separate critical notice at our hands hereafter. Passing from the Zoology to the Botany of the British Islands, we light upon a contribution to Flora which the past year has produced, of especial interest to the student of our native plants. Five years have elapsed since the Third Edition of Babington's Manual of British Botany appeared : in the Fourth Edition, which is now before us, we are again presented with " many additions and corrections," embodying the author's latest views on the limitation of species and varieties, with numerous accessions, from various sources, to the previous list of our native and naturalised plants. As in the former editions, care has been taken to distinguish between those species that are supposed to be truly indigenous and such as have been accidentally introduced and naturalized ; and many plants which had been, on insufficient evidence, admitted into the British Flora, are now excluded. The process of reduction might, perhaps, have been carried still further, with advantage. The whole volume gives evidence of the careful revision and correction which is spoken of in the preface, where we are specially referred to the remodelling of the extensive and difficult groups, Hieracium, Carex, and the whole order of Graminece. In reviewing those changes, we cannot but applaud the pains and skill which the author has bestowed on his subject, though, in many cases, we do not acquiesce in his views respecting species. Perfect agreement among naturalists, on the subject of the limitation of species and genera, indeed, is not to be expected, and our own views on this subject happen to differ widely from those adopted by Mr. Babington. To us it appears that the multiplication of species, on trivial grounds, has been carried by modern botanists to an excess, which has materially injured the science, and which, if followed up with equal zeal by the next genera- tion, will go far to reduce Botany to the chaotic state in which it was found by Linnaeus. If every form of plant that differs, by some little charac- teristic, from its fellows, is to be recognised as a distinct species, the process of species-splitting will be endless. Yet this seems to be the rule adopted by a large number of the Botanists of France and Germany. As an evi- dence of the absurdities to which it leads, we may instance the article Solatium, in a recent volume of De Candolle's Prodromus, where the 40 REVIEWS. common Solatium tuberosum appears under a score of names ; or, to look nearer home, we ask our botanical readers how many of them can distin- guish the thirty or forty " species" (so called) into which the common Bramble of our hedges has been divided? We ask, has anything been attained, except confusion, by the labours of modern botanists on the Rubus fruticosus of Linnseus ? Formerly every botanist knew, or thought he knew, a bramble when he met it ; but now scarcely two botanists, we suspect, are fully agreed on the nomenclature of the British species ; and, were they to extend their researches to all the countries over which the Rubus fruticosus L. and its kindred are dispersed, the difficulty of determi- nation would be greatly increased. Even in comparing the Brambles of Germany with those of England most puzzling difficulties arise, as is evi- dent from the constant changes of name to which the supposed species are liable. But the same difficulty occurs in attempting to collate the British species, as severally understood by Messrs. Leighton, Bellsalter, Lees, and others, who have most attended to the subject ; as may be seen by the synonyms collected under almost every species admitted into the Manual. We observe that, in the present edition, two have been struck off the list. We wish that Mr. Babington had carried retrenchment still further. Under his sixth section he observes, " The plants contained in the section are far from being determined satisfactorily ;" — a remark which we would venture to extend to the whole six sections. We observe, too, that when a " spe- cies" is exploded, its debris is frequently parcelled out between several other " species" — not greatly adding thereby, we should think, to their stability. Thus we are told " the plants formerly included under the name of R. Babingtonii are now referred respectively to R. scaber, R. pyramid- alis, and R. fusco-ater /3. Colemani." Again : " R. Wahlbergii (Bab. not Arrh.) is now placed partly under R. Corylifolius and partly under R, nemorosus." In our opinion, the fact of such intermediate forms, as these appear to be, occurring between other closely allied forms, ought to prove to the conviction of any one but an enthusiast the worthlessness of the distinctions which separate those that are still retained. Among the changes introduced in the present edition we are first struck by the disappearance of Ranunculus aquatilis, and the substitution of six species — R. trichophyllus, R. Drouetii, R. heterophyllus, R. Baudotii, R. Jloribundus, and R. peltatus — in its place. We had supposed that the process of hair-splitting had been already sufficiently exercised on the Batrachian Ranunculi ; but this large addition to their number shows how much may still be done by ingenuity. Other additions to the British list MANUAL OF BRITISH BOTANY. 41 are Polygala austriaca, found in Yorkshire ; Hypericum anglicum, a de- tachment from H. androsasmum ; Epilobium anagallidifolium ; Galium mon- tanum, G. commutatum, and G. elongatum ; Salix acutifolia ; Orchis incarnata, separated from 0. latifolia ; Epipogium aphyllum, perhaps the most remarkable addition to our Flora recently discovered ; Arum itali- cum, found in the Isle of Wight ; and the following Filicoids and Ferns: — Equisetum Moorei, " probably not distinct from E. trachyodon ;" Asple- nium acutum (a form of A. adiantum-nigrum) ; Pseudatkyrium alpestre, and P. flexile, the latter M a doubtful species ;" Gymnogramma lepto- phylla ; Botrychium rutaceum, and Ophioglossum lusitanicurn. The new distribution of the difficult genus, Hieracium, demands special notice. In treating of this group the author expresses himself to be under great obligations to the researches of Mr. James Backhouse, jun., who has carefully collected and published most of the British forms. In looking over the list now given, we find that no less than eight of the names admitted into the third edition are omitted, but, as a compensation for this, fourteen new names are introduced — leaving a balance of six in favour of the extension of our Flora. Most of the novelties appear under names given by Mr. Backhouse, and are, there- fore, regarded by the author not merely as additions to the British list, but as absolutely new Species. And these fourteen novelties have been disco- vered on ground which, for the last fifty years, has been more traversed by botanists than almost any other district in Britain. We are not pre- pared to criticise the characters attributed to all these supposed new spe- cies ; but the fact of so many new species having all occurred to a single young and ardent observer, in a field so well beaten as that of the English and Scotch Highlands, does not inspire much confidence in their perma- nence. Every one familiar with Hieracia knows that the Alpine kinds especially are subject to infinite variation ; and we suspect that it will be more easy for future explorers of the Highlands to discover a dozen other equally distinct types, than to refer, with certainty, the forms that may occur in their rambles, to those now attempted to be defined by Mr. Back- house. We shall have a repetition of the story of Rubus fruticosus and Solanum tuberosum. And, supposing the other genera of Composite to advance at the same rate, we may soon expect a galaxy of new Dandelions and Cat's-ears. Surely, the varieties of Leontodon taraxacum, Apargia autumnalis, Hypochceris radicata, ' and other common plants, are as de- serving of special description and name as some of the forms now sepa- rated from Hieracium alpinum and its allies. Most of our common field F 42 REVIEWS. and wayside Composite might be similarly treated ; and Arctium already shows, by the addition of three new names, what may be done when such common plants as Burdocks are properly investigated and minutely exa- mined. Obviously we do not yet know the riches of our fields. Various changes have been introduced into the arrangement of the species of several of the large genera ; and, evidently, much care has been bestowed on them with a view to render the distribution lucid. Carex especially appears to have been very carefully worked over again ; but no new species is added in this edition. The most important change occurs in the order Graminecc, which is now divided into two sub-orders, the ClisanthecB, distinguished by closed flowers, with long stigmas protruded at the top of the flower ; and the Euryanthece, with open flowers and short styles, the stigmas protruded at the bottom of the flower. These groups seem to be natural, and are readily to be recognised by characters simple and easily observed. Some alterations are made in the position of the genera : thus Nardus and Lepturus are widely separated, the former being placed as the type of a family, Nardece, in the first sub-order ; and the latter referred to Hordeinece in the second. Arundinacece is combined with Agrostidece, and Lagurus from Avenece added. Milium, is referred to Sti- pacecej and Knappia transferred from Phleinece to Chloridece. The reductions of species are less numerous than the additions. Tha- lictrum majus, Sm., is reduced to T. fiexuosum ; Camelina sativa is ex- pelled, and C. foetida substituted ; Epilobium virgatum is reduced to E. obscurum ; Saxifraga Andrewsii is excluded as a garden hybrid ; Helos- ciadum repens restored to H. nodiflorum ; Galium pusillum of E. Bot. changed to G. sylvestre. Poll. ; Libanotis united to Seseli ; Cineraria to Senecio; Salix fusca to S. repens, S. Forbyana to S. rubra, and S. helix to S. purpurea; Orchis fusca is changed to 0. purpurea ; Phleum commu- tatum to P. alpinum, and Festuca sciaroides to F. myura. On the whole, the present edition bears out the announcement on the title-page, that it contains " many additions and corrections." A recent discovery in Art, interesting to all Naturalists alike, is the process for obtaining Photographic images in relief ; from which electrotype Copperplates can be taken, that yield very clear and delicate impressions. This long-sought-for invention promises to afford multiplied pictures of Natural objects, of complicated form, or intricate pattern, cheaper, at once, and more accurate than Engraving can accomplish. A. H. H. & W. H. H. GLAUCUS, 43 Glaucus ; or, The Wonders of the Shore. By Charles Kingsley, F.S.A., Author of "Westward Ho!" "Hypatia," &c. Third Edition, Cor- rected and Enlarged. 12mo. Cambridge : Macmullen & Co., 1856. Price 3s. 6d. We have already made this little book the subject of a Review (see vol. for 1856, p. 5), but the appearance of a new Edition, corrected and enlarged, will, no doubt, be a sufficient apology with our readers for in- troducing it again to their notice. We know that some people have an objection to new Editions, with Additions, and think that the additional matter ought at any rate to be also published in a separate form ; but it appears to us perfectly natural that an author should employ his additional knowledge in improving, at each successive edition, any work that he has written, and amplifying it with any fresh ideas to which the previous context may lead him on. Yet the publication of this fresh matter, sepa- rately, from that which led to it, would, in most cases, be simply absurd. On a close comparison of this Third Edition with the second we find verbal alterations at pages 23, 48, 74, 97, and 165, and the following additional matter— viz. : pp. 110-117, 118-125, 154-160, 166-168. Some por- tions of the extracts from Mr. Gosse's works, which appeared in the pre- vious Editions, are omitted in this ; thus we get some 24 additional pages, without any increase in the size of the book. The first verbal alteration occurs in the sentence which created such a stir in the hive ; we allude, of course, to the passage in which we were told " our home botanists, entomologists, and ornithologists are spending their time now, perforce, in verifying a few obscure species, and bemoan- ing themselves, like Alexander, that there are no more worlds left to con- quer." In the new Edition the word " Entomologists" is here omitted, but we find it transferred to the following sentence : — " For the geologist, indeed, and the entomologist, especially in the remoter districts, much re- mains to be done, but only at a heavy outlay of time, labour, and study ; and the dilettante (and it is for dilettanti, like myself, that I principally write), must be content to tread in the tracks of greater men who have preceded him, and accept at second and third hand their foregone con- clusions." This will not do, Mr. Kingsley. You must retouch this sentence for the next Edition, or you will again have the Entomologists down upon you. We boldly affirm that for the Entomologist much remains to be done without any heavy outlay of time, labour, and study. Hear Mr. Douglas, in " The World of Insects," p. 4 : " It is true a popular writer (the Rev. 44 HE VIEWS. C. Kingsley, in "Glaucus," 1855) has lately said that the field of Ento- mology in Britain is fully explored j but I beg to assure him and his readers that such is not the case, for the chances are that, out of fifty per- sons who should this year begin to collect insects, twenty-five would each discover either a new British species, or a new fact in insect economy f Mr. Kingsley and Mr. Douglas on this subject are evidently at variance ; they cannot both be right, and though we have a great respect for Mr. Kingsley, we are disposed, on a question of Entomology, to repose more confidence in the assertions of the author of that capital book, " The World of Insects." The additional matter at pp. 110-117 relates to sea- weeds and marine plants. Take as a sample the following, at p. 116: — " Not merely interesting, too, but brilliant in their vegetation, are sandhills ; and the seemingly desolate dykes and banks of salt marshes will yield many a carious plant, which you may neglect if you will; but lay to your account the having to repent your neglect hereafter, when, finding out too late what a pleasant study botany is, you search in vain for curious forms over which you trod every day in crossing fiats, which seemed to you utterly ugly and uninteresting, but which the good God was watching as carefully as He did the pleasant hills inland— perhaps even more carefully ; for the uplands He has completed and handed over to man, that he may dress and keep them ; but the tide-flats below are still unfinished ; dry land in the process of creation, to which every tide is adding the elements of fertility, which shall grow food, perhaps in some future state of our planet, for generations yet unborn." At pp. 118-125, we have allusion to various dredging grounds, and much specially about Hastings, of which Mr. Kingsley says — " As the place is so much visited by Londoners, it may be worth while to give a few hints as to what might be done by any one whose curiosity has been ex- cited by the salt water tanks of the Zoological Gardens." So by all means let the reader, if he is going to Hastings, put a " Glaucus, 3rd Edition," in his carpet-bag. In our previous notice we observed, " It may well be doubted whether any previous book has appeared for years past which has done more to pro- mote the study of Natural History than the little book we have now under consideration will certainly do," and entertaining this opinion, we are pleased to perceive that the demand for this book is so great that already more than 5,000 copies are in circulation. We notice the 3rd Edition is advertised at the " 6th Thousand." A work that in eighteen months has attained such a circulation stands a fair chance of eventually attaining its " Twentieth Thousand." We trust that Mr. Kingsley, accordingly, will gather together, from Naturalists of all classes, any hints — and surely they owe him every contribution in their power — that might possibly assist him for the " Fourth Edition." 45 Geographie Botanique raisonee ou Exposition des faits principaux et des lois concernant la distribution geographique des plantes dk l'epoque actuelle. Par M. Alphonse De Candolle. 2 Vols. Paris. 1855. The illustrious name of De Candolle has long stood among' the first in the first rank of philosophical botanists. The elder De Candolle, father of our present author, and universally known to every working botanist through the indispensable " Prodromus" contributed upwards of 140 treatises to botanical science, many of them works of considerable extent, and all of them marked with abundant proofs of the original research and ability of the writer. The publication of these works extended over a space of forty- four years — a long and glorious career of mental activity. They include essays or treatises on every department of Botany — the structural, physio- logical, systematic, economic, and geographical — and have deservedly ac- quired for their author a fame imperishable, while Botany shall exist as a science. It is no light matter to inherit the name of such a father. It is no easy task for a son, standing at the base of such a pyramid, to prove himself equal to his position ; aud we cannot speak in higher praise of M. Alphonse de Candolle than by saying that he has proved himself not unworthy of such parentage. His works, indeed, have been few and re- stricted in subject, in comparison to those put forth by his father ; but they are sufficient to prove his ability as a botanist, and to establish the fame of any ordinary person. The work now before us is, perhaps, his most important contribution to Botanical science, and is obviously the fruit of many years' thoughtful study and laborious research. It treats in detail, and at great length, of the general and particular relations of plants to climate and soil, and their dis- persion over continents and islands. The subject is divided into twenty- six chapters, grouped under four books, and fills 1334 closely printed octavo pages. We can only attempt to give a very brief account of an essay which branches out into innumerable subjects, the discussion of any one of which would be sufficient for an article. The first book discusses with some detail, but in a general way, the effects of temperature, light, and humidity on the development of vegeta- tion. The author commences by exposing the false views popularly en- tertained with respect to the relationship between plants and the climate in which they live. Many persons suppose that the presence or absence of such-and-such forms of vegetation is a certain indication of a precise cli- 46 REVIEWS. mate, as if each plant individually were a sort of natural thermometer. This incorrect notion has been perhaps chiefly mischievous in reference to the obscure regions of fossil Botany, where certain climates have been hastily assumed to have existed in certain localities at a former epoch be- cause certain forms are found fossilized in the strata. Thus, because Za- raias are now found at the Cape of Good Hope, in New Holland, and in the table-land of Mexico ; and because fossils of kindred structure are embedded in the strata of England, and of other northern countries, it has been as- sumed that the England of the Zamian era must have had a similarly hot and dry climate to that of South Africa, or of Western Australia, where these forms of vegetation are now common. The inference is, however, a very vague one, resting on a very narrow basis, as will be evident when we examine a little more carefully the climates where the Cycadeae are now found. We shall then discover that though none inhabit a very cold country, yet the range of climate, especially as regards humidity, over which the Order is distributed is very extensive, some species growing in the moist jungles of tropical India, others in the low islands of the Pa- cific archipelagos, besides those more familiar forms which we have from the arid regions of the Cape and Australia. It would be impossible to tell from the mere inspection of a modem Cycadeous stem and foliage whether they had grown in a tropical or extra-tropical climate ; and it must be just as hazardous to pronounce on the nature of the climate which nou- rished Cycadeae in the earlier eras of our planet. It would be as reason- able to judge from the finding of fossil acorns or oak logs that such indi- cated a climate in the regions where they occurred similar to that of modern England, of which the oak may be taken as a characteristic tree. But in this hasty assumption we should t,lose sight of the fact that the genus Quercus has a wide distribution in tropical as well as intemperate and cold latitudes, species being found from very high latitudes on the American continent nearly to the equator, and occurring on the mountains and table- lands of tropical India, and of the island of Java. Were the species of oak now existing in Java fossilized there, leaving no descendants, some future geologist, knowing the oak only as a form of vegetation of cold or tempe- rate regions, might draw, from its presence in the strata of Java, a very false inference respecting the early climate of that tropical island. That a plant does not indicate a particular climate in a manner analo- gous to a thermometer or hygrometer must be evident to any one at all acquainted with the powers of endurance which certain species display, and the feebleness of endurance equally obvious in other species ; so that each GEOGRAPHY OF PLANTS. 47 species of plant has in some degree its own charter, one enjoying more ex- tensive privileges than another. Nor, until we have ascertained the facts regarding species bj particular observations, can we with certainty foretell what will be the effect of change of climate upon them. What would be more natural to suppose than that all the plants spontaneous at the Cape of Good Hope, supposing they occurred at a tolerably uniform elevation above the sea, would be influenced by change of climate in a like degree ? Their native climate is a very remarkable one — remarkable for the intensity and amount of solar light throughout the year ; for rapid changes of tempera- ture, and for the very unequal distribution of moisture at different seasons. We should expect among them a common feeling — so to say — on their re- moval to this country ; and such, to a certain extent, is the case. But the exceptions are very numerous ; for while some — such as the Heaths and Pelargoniums — flourish and actually improve in the artificial climates of our green-houses, others — as many of the bulbs — are with difficulty induced to blossom, and rapidly degenerate. As might be expected, most Cape plants require the protection of glass in winter ; but to this there are many remarkable exceptions. The Aga- panthus flowers freely in the south of Ireland, in the open ground, from year to year ; and the Tritomanthe (hot-poker plant) is even still more hardy; for we have seen it raising its spike of scarlet flowers uninjured from among the snow. Yet this plant is a native, not of high mountains or table-lands, but of the low plains at the Cape, where the thermometer may stand on a summer day in the ground, close to its roots, at a height of 130° to 1 60°. When we find such wide discrepancies as these among plants of the same region, we may well agree with our author in maintaining that the question of the relation of plants to climate is a very complicated one ; and that we can only rightly understand it by regarding plants as " living machines," having a certain work to do, and struggling to perform it at all hazards, fighting under difficulties against physical agencies. Beyond a minimum of light, heat, and moisture, life ceases. With fair proportions of these (according to the wants of each individual species) it is maintained with vigour ; and there are a thousand intermediate stages of excess or de- ficiency in which a struggle for existence is by the more hardy species maintained. After discussing the effects of light, heat, and moisture in general, M. de Candolle divides his subject into two principal sections, which he distin- guishes by the names Geographic Botany and Botanical Geography. By the first of these he understands the consideration of species, genera, and 48 REVIEWS. families of plants in a geographic point of view ; and by the latter, the con- sideration of different regions of the earth with respect to the vegetation which clothes them. The first division, or Geographic Botany, offers the widest field of research, and forms, indeed, the bulk of the treatise, occupy- ing sixteen of the chapters, and filling nearly 1100 pages. We can only briefly allude to a few of the subjects treated of. The first chapter, a very important one, runs over 300 pages, and discusses, under the varied circumstances which influence the dispersion of plants, their limitation on the plains and on the mountains. The limits occupied by spontaneous plants on the plain, or at a moderate level above the sea, in a direction towards the pole, and towards the equator, are illustrated by detailed accounts of certain well-known annual, perennial, and ligneous species. Each of the indicated limits is then separately discussed, and this is fol- lowed by general considerations on the polar and equatorial limitation of each description of vegetable. We have then the limits in altitude of spon- taneous plants similarly treated ; and, finally, cultivated plants, whether on mountain or plain, are subjected to a like analytical examination. The next chapter discusses what the author calls the "form" of the habitat of species — namely, the differences in the diameters of the area occu- pied by different species, when the line is drawn east and west, or north and south, or in some intermediate directions. Some curious facts are noted on this subject, and obviously this chapter deserves to be more extensively worked out. The author has limited his observations to the species con- tained in the eighth, ninth, and tenth volumes of the " Prodromus," asw offering sufficient illustration of his subject, and finds that of the 8,495 species contained in those three volumes, there are only 116 which present any very marked differences (four times at least) between the lengths of the opposite diameters of their areas. The remaining 8,372 species appear to occupy more or less circular areas — a remarkable fact. It must be observed, however, that this examination refers exclusively to certain orders of the Corollijlorce, whose distribution can hardly be taken as fairly representa- tive of that of Phanerogamous plants in general. Of the 116 species se- lected by M. de Candolle, sixty-eight extend east and west, and forty- eight in a naiTOW line north and south. One should hardly have a priori anticipated so nearly equal a division of the number, it seems so much more natural that a species should extend along the parallels of latitude, or, at least, in the isothermal lines, than along those of longitude. We are thus taught that other causes than those of annual temperature powerfully influ- ence the natural dispersion of plants. The most potent, probably, are GEOGRAPHY OF PLANTS. 49 moisture, and exposure to certain winds. Of the forty-eight species enu- merated as having a north and south distribution, only two are natives of Britain, namely, Pinguicula lusitanica, which extends along the Atlantic shores from Portugal to the north of Scotland, but which is not found any- where far from a western coast ; and Erythrcea latifolia, likewise a coast species, found from Norway to Portugal. The distribution of individuals in the areas occupied by the species is next discussed, with considerable detail, showing how local causes modify the frequency or non-frequency, or the luxuriant development, of each species. The nature of the soil, exposure, supply of moisture, and other obvious modifying causes are indicated, and a list is given, after Mohl, of species which are characteristic of primitive rocks, and of those which only occur in calcareous soil. M. de Candolle seems to think also that some- thing like a " rotation of crops" exists naturally among wild plants, and that a species shifts its soil (especially an annual one) from year to year, from causes similar to those that force the farmer to vary his seeds when cultivating the same soil. " One cannot doubt," he says, " that the exist- ence of a species, and especially its prolonged existence, becomes a cause unfavourable to the life of that same species, or of analogous species, in the same soil." The well-known fact that when a natural forest is burned or cut down, trees of different species commonly spring up in the room of those destroyed is adduced in proof of the necessity of rotation ; and the hypothesis of the elder De Candolle, that roots discharge excretory matter, so as to poison the soil for themselves, is dwelt upon as an established fact. The seventh chapter treats of the area or space on the surface of the globe over which a species extends. This important subject has for a long time engaged the author's attention, and the result now given must have cost years of toilsome research. The value of this research must, however, in great measure depend on the author's views as to the limits of the species themselves. In the hands of some writers who establish " new species" on every local race, if it differ by a hair's breadth from their " typical" form, a chapter like the present would only lead to confusion. Fortunately for science, M. Alphonse de Candolle is content to call " Ra- nunculus aquatilis" by its single name, and consequently finds it to extend over the northern hemisphere, from Lapland to Abyssinia, and from the 68° parallel of north lat. in America to California. Had he chosen the opposite course, he might easily have treated us to a crowd of " representa- tive species," each peculiar to its own pond or ditch, over the same extent of surface. 50 REVIEWS. For purposes of comparison the world is divided into fifty " regions," each supposed to indicate a more or less marked flora, and defined by strougly marked geographical limits and climatal peculiarities. Thus, there is a well-marked arctic region comprised within the polar circle, and common to Europe, Asia, and America. Many of the species characteristic of this region appear again on the limits of perpetual snow in more southern climates, and yet the alpine flora, taken as a whole, is very distinct from the arctic. Europe, minus its arctic portion, is divided into two well marked regions, the temperate or Northern and Midland States, and the Mediterranean, including the shores of that sea, as well as the whole Iberian peninsula. Some of the detached Atlantic Islands, such as St. Helena (with Ascension), and the minute Tristan D'Acunha, are distin- guished as separate regions, and apparently with justice, so very peculiar is their flora, especially of the former. Such minute specific centres contrast strongly with our author's 29th region, which comprises the Australian continent, with its outliers, Tasmania, New Zealand, Norfolk Island, and New Caledonia. North America, east of the Rocky Mountains, and as far south as the mouths of the Mississippi, forms another extensive, but well marked region. Brazil is divided into three regions, and the remain- ing portion of S. America into ten ; so varied is that continent, in different parallels, in its vegetable productions. The author does not lay much stress on the exactitude with which his regions represent natural limits ; indeed, he states that his arrangement is defective on several points, but having commenced to tabulate on this basis it was necessary to go on with it. Tables are given illustrating the area occupied by species and families. From these it appears that the comparatively small family of Papaveracew includes some of the most widely dispersed plants, one of its species (Arge- mone mexicana) occurring in eleven regions, while Myrtaceae, a very ex- tensive order, is specifically very local, only three out of its 700 species occurring in three regions. Of Papaveraceae, 68 per cent., Cruciferae, 75 per cent., Campanulaceae, 89 per cent., and Myrtaceae, 97 per cent, consist of species limited to a single region. Next follow tables contrasting the floras of different countries, the first table, illustrating that of New Holland, being copied from Mr. Brown, who states, that out of 3,760 flowering plants known (in 1814) as natives of Australia, 45 are common to Europe. Since that date the number of Australian species has been doubled, but not many more European species have been detected. Perhaps one of the most remarkable discoveries of late years has been that of Lysimachia vulgaris, found by Dr. F. Mueller in the alpine region of Victoria, far removed from GEOGRAPHY OF PLANTS. 5 1 any settlement. Of course, the progress of colonization has introduced a vast number of European weeds, some of which, especially the thistles, bid fair soon to supplant weeds of natural growth, and in a few years the local botanist will be puzzled as to the claims of many plants, whether indige- nous or naturalized. The flora of New Zealand contrasts remarkably with that of the larger island, for out of the 730 flowering plants described by Dr. Hooker, 223 are common to other countries, and 60 are common to Europe. Of the 113 species found at Norfolk Island, 61 are peculiar to that island, 52 common to other countries, and 8 also natives of Europe. The little island of Tristan Da Cunha, so well explored by the late Captain Carmichael, contains 32 species of flowering plants, 26 of which are found nowhere else. We have next tables to show the proportion, by families, of species common to widely separated countries. The facts are similar to those just stated, but given more in detail, and illustrated by more nume- rous examples. Then follow tables showing the proportion, by fami- lies, of species dispersed over more than two regions, and the mean area of species considered in reference to the nature of their habitats, whether aquatic, moist, or dry ; relative to their duration, whether annual, biennial, perennial, &c. ; their degree of lignification, whether trees, shrubs, or suffrutices ; and lastly, relative to the nature of their seeds, whether the fruit or seed be winged or fleshy, whether the seeds be numerous or few, small or of large size, soon perishable or capable of long existence in a dormant state. It is impossible in this hasty sketch to do justice to the care with which these and other details are worked out. We can only mention a few of the results. With respect to habitat, it appears that 17 per cent, of submerged or floating flowering plants are common to more than two regions, 9 per cent, of marsh plants, 7 per cent, of the plants of wet ground (not strictly marshes), 10 per cent, of maritime plants, and 7-10 per cent, of parasitical plants. Out of 389 purely parasitic plants noticed, only three are found in more than two regions. The half parasites, such as Orohanche, Monotropa, and Cuscuta are more dispersed, 8 per cent, being found in more than two regions. Of families chiefly consisting of annual species, 7 per cent, occur in more than two regions ; of perennial herbaceous families, 5 per cent. ; and of those composed of trees and shrubs, less than 2 per cent. A considerable number of arborescent plants are limited to one or two regions ; out of 2,321 species enumerated, only 43 exceeding those limits. Out of 292 coniferous trees, 12 are widely dispersed, a large per centage when compared with most other ligneous families. One would 52 REVIEWS. have supposed that winged seeds were favourable to the dispersion of species, but M. de Candolle's tables show a different result. In almost every family enumerated, the per centage is in favour of naked or wingless seeds, remarkably so in Dipsacece, where 11 per cent, of species with cal- vous seeds are widely dispersed, while only 3 per cent, of those furnished with pappus enjoy as wide a range. Among the Composite the propor- tions are as 4*5 to 2*9 per cent, in favour of calvous seeds, by which it should follow that daisies were twice as diffusable as thistles or dandelion. A list is given of 117 species, which occupy very large areas, " at least a third part of the surface of the globe." Out of these, 1 00 are natives of Britain. Many of them extend over much more than the third part of the earth's surface, but none appear to compass the whole earth, however wide their extent. " The Stellar ia media (chick weed), for example, which en- dures very severe climates, and easily becomes naturalized in temperate regions, is found neither at Melville Island, nor in Labrador, nor under the Equator." "Nettles themselves, which one looks upon as accompanying man, do not support, like him, the extremes of cold and heat ; they are wanting in Labrador, Melville Island, as well as on the plains of the torrid zone. The Portulaca oleracea, Sonchus, Lamium amplexicaule, Chenopo- dum album, Cynodon Dactylon — plants that may be looked on as univer- sally diffused, so common are they, and so easily naturalized — do not pene- trate into the extreme northern climates. One alone, the Sonchus olera- ceus, is, perhaps, so organised as to endure all climates, from the equator to the pole ; but it needs a cultivated soil or rubbish ; and such stations are wanting, and always will be so toward the extreme north. Thus, I repeat, no phanerogamous plant is or can become a cosmopolite in the absolute sense." The number found to occupy half the globe is extremely limited, only 18 being enumerated out of the 117 first named. Many of the most widely dispersed are either purely aquatic or frequent very moist situa- tions ; 14 or 15 species are natives of Very dry places, and from 25 to 30 are chiefly found in cultivated ground. Many littoral species, which would have found a place in the lists, if the calculations had been based on parallels of latitude or longitude, are excluded, because, though widely dispersed geographically, they extend too short a distance from the shore to form large areas of distribution. No tree or shrub figures in the list* The Thymus serpyllum is the most ligneous plant, if we can call it an " undershrub." Of the species enumerated 47 are annuals, 3 biennials, and 66 perennials ; 73 are dicotyledons, and 44 monocotyledons — that is, in the proportion of 62 per cent, dicotyledons to 38 per cent, monocotyledons. GEOGRAPHY OF PLANTS. 53 And as the proportions of these classes in the vegetable kingdom are as 83 to 1 7 per 1 00 species, the facts stated confirm the greater mean area of monocotyledons over dicotyledons. A much shorter list is given of species having a very limited area, not because such plants are less numerous — for the contrary is unquestionably the fact — but because it is difficult to ascertain the exact limits occupied by such species, except when they occur in very remote islands, or in countries thoroughly explored by botanists. The island of St. Helena contains several species, and even arborescent genera (of Composite), which are not only found nowhere else, but which are confined to very small areas on the island. The noble tree-fern, Dicksonia arborescens, occurs only on the summit of Diana's Peak, the crown of the island. Kerguelin's Land is the only known habitat for the genus Pringlea (Capt. Cook's cabbage) ; the Auckland Islands, Tristan Da Cunha, Juan Fernandez, Madeira, and other small islands, all contain species or genera peculiar to themselves. The famous Cocos de Mer, or Double Cocoa nut (Lodoicea secliellarum), a most remarkable and distinct genus of Palms, is only found at the rocky islets of the Sechelles, and only inhabits a few of the group. In like manner, each of the Canary Islands has species peculiar to itself; and this is still more remarkable at the Gallapagos, of which group Dr. Hooker has pub- lished an excellent flora (in the 20th vol. of Linn. Trans.). But limited dispersion of species is not confined to remote islets. It occurs in con- tinents. Several instances of extremely small areas of well marked species occurring in Europe are given by M. de Candolle. To these we may add a few exotic examples : — Dionoea muscipula, certainly a very remarkable plant, not likely to escape the notice of American botanists, is limited to a very small area in North Carolina (where it abounds), and a single station in South Carolina. In like manner, the curious Cephalotus follicularis, the Australian Pitcher Plant, which abounds in all the bogs round King George's Sound, has been found nowhere else. The species, too, of Nepenthes appear to be very local, each tropical island in the area occupied by the genus having its peculiar kind. Disa grandijlora, the most showy of terrestrial Orchideae, having a flower sometimes five inches in breadth, with crimson petals, is only known on the borders of a little streamlet on the summit of Table Mountain, at the Cape ; but along that streamlet the plant is abundant. But many Orchideae, we suspect, have a very limited extension. It is well known that the Cape flora is peculiarly rich in species of Erica, upwards of 300 having been described. Several of these are extremely local, while others are found scattered over many 54 REVIEWS. hundreds of square miles, from the western districts to Port Natal. The same may be said of many of the Proteacese, both of the Cape and of Australia. Every district, of no great extent, supplies its own peculiar 6pecies. Even some genera, such as Franklandia and Bettendena, are confined to very small areas. Clianthus puniceus, so well known in our gardens, is much more likely to be preserved in cultivation than in New Zealand, its native country, where its range is very limited. The causes operating on the natural extension of species are summed up under three heads, namely : — transportation, more or less easy, or more or less frequent, of seeds in a germinating state, such transportation being effected either by currents, or incidentally through the agency of animals or man ; connection or separation more or less real of countries having more or less analogous climates ; and lastly (and, as we believe, chiefly'), the physiological peculiarities of each individual species. Besides these actually existing causes, others may have formerly operated ; for example, there may have been different means of transport at another geological epoch ; islands now widely separated from continents may have formerly been connected ; some species, very widely dispersed, may have an earlier date in creation than others ; or the original number of individuals of different species may have been different ; for we need not necessarily suppose, in the vegetable kingdom at least, that every species spring from one or two individuals. The changes which take place in the habitats of species form the sub- ject of the eighth chapter. The question of naturalization* is largely dis- cussed, and copious lists are given of species naturalized at short or at long distances from their native localities. Some of these species, now widely dispersed, are of recent introduction. Mimulus luteus, introduced from North America to our gardens so lately as 1812, has been found "appa- rently wild" in many parts of the Highlands of Scotland. We have also seen it in the Wicklow mountains ; and M. de Candolle states that it has spread along the streams in many valleys of the Vosges. Its American habitat is extensive, reaching from Unalaschka, on the north, to Chili. (Enothera biennis (the " evening primrose"), a native of North America, introduced 1619, has become so disseminated over the greater part of * At p. 714. the author makes a strange blunder in confounding Stratiotes aloi- des, Z., with Pistia stratiotes, L. Which of these plants is naturalized in the tanks at Marly, we cannot say; but it is Pistia stratiotes — not "Stratiotes aloides," as stated — which is a native of the Molluccas, Java, Malabar, and other intra- tropical countries. Stratiotes aloides, we need hardly say, is a well-known European plant, and a native of England. GEOGRAPHY OF PLANTS. 55 Europe, that some modern botanists have questioned its exotic origin. It is equally common, in the neighbourhood of cultivation, in South Africa, and is spreading in Australia. The recent appearance of Anacharis alsinastrum in English canals and rivers is a remarkable instance of the rapid dissemination of mis- chievous exotics. These and several other plants — some of them trouble- some weeds — Europe owes to America ; but she has more than returned the gift in the number of species she has transmitted, and the extent of surface they cover. Whoever has travelled through the United States must have been struck with familiar road- side, hedge, and field- weeds, reminding him of home. Two species of mullein (Verbascum Thapsus and V. Uattaria) are specially common by roadsides, and in recent clearings and along the borders of railway cuttings, as if their seeds were widely and abundantly dispersed in the soil ; yet they are unquestionably introduced from Europe. The Leucanthemum vulgare (ox-eyed daisy) is a far more troublesome weed in America, its adopted home, than it is in Europe ; and so of many other European weeds, now rapidly extending with cultivation over the whole surface of North America. In Australia there is no native species of thistle ; but European thistles have become such pests, even in the recently settled colony of Victoria, that the legislature has been obliged to pass an Act, enforcing penalties on the farmer who shall not duly eradi- cate the thistles on his ground. In Tasmania, the sweet briar (Rosa ru- biginosa), though but a few years ago introduced to gardens as a memento of home, has become wild, and in some districts already forms dense thickets which extend rapidly year by year, the innumerable hips being dispersed by birds. In many places already it must be regarded as a pernicious weed. Vlex europceus (the furze-bush) has likewise escaped in Tasmania, and, as on the highlands of St. Helena, flourishes abundantly. Anthem is nobilis is also completely naturalized, and in some places we have seen whole fields occupied with it, almost to the exclusion of other herbage. To the chapter on naturalizations succeeds a history of cultivated plants, tracing the origin of the species most notably cultivated for their roots, tubers, bulbs, stems, leaves, flowers, fruits, or seeds. At the head of the list stands the Potato (Solanum tuberosum), which is stated to have been found in cultivation, at the time of the discovery of America, " in all tem- perate regions from Chili to New Grenada, but not in Mexico." (Humb.) The fact of its having been also cultivated by the aborigines of North Carolina, from which place its roots were brought by Raleigh, is questioned, and we think justly so, the authorities in support of the story being few 56 REVIEWS. and vague ; while the evidence against its cultivation by the aborigines appears strong, if not conclusive. If Raleigh found potatoes in North Carolina, they were probably transposed thither by the Spaniards. The potato has not been found wild in any part of the United States, nor was it known to any of the aboriginal tribes before the settlement of Europeans. Such is the joint opinion of Professor Asa Gray, the most competent botanist of America, and of Dr. Harris, Librarian of Havard University, an equally competent authority in questions affecting the early history of America. The Manioc, Manihot, or Tapioca Root (Jatropa Manihot), so important an article of food in the West Indies, is referred to, having been found extensively cultivated at the time of the discovery. It had been erroneously stated by the Abbe Raynal to have been introduced from Africa ; but modern botanists have shown that the genus abounds in species in tropical America, while none have been found wild in tropical Africa, a circum- stance obviously in favour of the American origin of the cultivated kind. Species of Dioscorea or Yam, wild and in cultivation, are found through- out the tropics of both hemispheres, rendering it difficult at the present time to determine what may have been the origin of the cultivated kinds. Not- withstanding their extensive cultivation in India, they have no Sanscrit name. It is disputed whether the name Yam or Igname be of African or of American origin. On the whole, the author refers the probable original centre of Yam -cultivation to the Indian Archipelago and the Southern extremities of Continental Asia. The native country of our common Jeru- salem Artichoke (Helianthus tuberosum) is unknown ; the species is nowhere found in a wild state. It has been known in European gardens from the beginning of the seventeenth century, and Columna, who saw it, in 1616, in the gardens of Cardinal Farnese, names it Aster peruanus tuberosus. Parkinson calls it Batatas canadensis; Bauhin, Chrysanthemum latifo- lium brazilianum. All these names seem to betray an American origin, and De Candolle fixes on the temperate parts of Peru as being the most probable native soil. Hemp and Flax, the earliest cultivated of textile materials, are both referred to the temperate parts of Asia, in the Caucasus, and towards the borders of the Caspian Sea. Hemp is still found wild in Northern India, and Flax in certain districts of Russia ; but it must be extremely difficult to discriminate between the wild and naturalized condi- tion of plants of such early and extensive cultivation. The Sugar Cane is a native of tropical Asia, cultivated from very early times in China, but not anywhere found in a state of nature. It was introduced from Arabia, in the Middle Ages, into Egypt, and thence into Sicily and the South of GEOGRAPHY OF PLANTS. 57 Spain. It was transported into the Canary Islands in 1 503, and soon afterwards found its way to the West Indies and Brazil. Of plants culti- vated for fruits (we omit tropical fruits) the several varieties of the Orange and Lemon are traced to the warmer parts of Asia ; the Vine, to the Cauca- sian region, where it is still found wild ; the Strawberry, Raspberry, Cherry, and the many varieties of Plums are from temperate Europe and Asia ; the Apricot from Armenia and the Caucasian region generally ; and so also the Almond. Peaches first made their appearance in Europe a little before the commencement of the Christian era, and their name, Persica, or Malum persicum, indicates their Eastern origin. They have, however, no Sanscrit name, and M. de Candolle supposes that they were originally brought from China. At present the Peach tree exists, apparently wild, in many parts of Asia: Koch affirms that it is abundant in the Cau- casian provinces, but Ledebour doubts if it be spontaneous there. Pears and Apples are of European or Caucasian origin ; the Quince is wild in the South of Europe ; the Pomegranate, to which Northern Africa is often assigned, is traced to Western Asia. The various Gourds, Melons, the Water Melon, and the Cucumber, all of which are now only known in cultivation, are traced to the East, whence they were introduced, at various periods, into Europe. Currants and Gooseberries are from temperate Europe. The Fig and the Olive, from early times naturalized throughout the Mediterranean region, are supposed to have been primarily derived from Asia Minor, or from that Caucasian district, the cradle of the human race, so abundantly supplied with the best gifts of the earth. The origin of the various species of grain, and of seeds used for other besides edible pur- poses, is discussed at length. The history of many of the best known is lost in antiquity. If they ever existed in a state of nature, they have long 6ince ceased to exist. The probability is that many of the so-called species of cultivation are races which have originated under man's care and skill, and which depend on his exertions for their continuance. If the experiments of a modern observer are to be depended on, wheat itself is a cultivated monstrosity of a miserable grass (JEgilops) of the South of Europe, which is so different in its botanical structure from cultivated wheat that it has been always supposed to be generically distinct. If such transformations are possible, others, equally startling, may have occurred. The subject of disjoined species, or those that are found scattered at wide intervals, without any apparent physical connection between the seve- ral localities where they occur, is next discussed at large. The origin of existing spontaneous species is then speculated upon ; the geographic dis- 58 REVIEWS. tribution of genera and of families is illustrated, and this division of the subject concludes with some general remarks on the changes which take place in the habitats of families, and the origin and derivation of these groups. Our limits do not permit us to enter into these subjects, which occupy ten chapters of the Essay. Nor can we do more than indicate the subjects contained in the remain- ing portion, called by the author Botanic Geography, in distinction to Geo- graphic Botany. Seven chapters are devoted to this section, which com- prises the following items : — General Characters of Vegetation ; Com- parisons between different countries with respect to the proportion of Dicotyledons to Monocotyledons, and a comparison with respect to the families most numerous in species, and to the families most characteristic of the country. Then follows a chapter on the variety of vegetable forms in different countries and in the entire globe ; the division of the surface of the globe into natural botanical regions ; and lastly, the vegetation of different countries is considered in regard to the probable origin of their species, genera, and families. In this last chapter the ingenious views of Edward Forbes iu relation to the origin of the Mediterranean species, which occur so abundantly in the West of Ireland, are favourably noticed. We must now conclude our hasty sketch, warmly recommending these volumes to the careful study of all persons interested in the subjects of which they 1 real. From the imperfect abstract we have given it will be evident that the questions of the climatical relations of plants are treated with great minuteness, with much learning and research, and the material ably and laboriously worked up. It is a work which will at once take rank as a text-book, to be referred to, not as a complete essay, exhausting the subject, but as a storehouse of information, uniting within a moderate compass most of the observations yet recorded, and serving, therefore, as a stable basis for further research. The subject of Botanic Geography, so far from being exhausted, is only yet in its infancy, and no doubt many of its facts will be read differently hereafter ; but we think that the principles stated and advocated in the present treatise will, as a whole, stand the test of time. W. H. H, 59 " cours elementaire d'hlstoire naturelle, zoologie par m. mllne Edwards, ouvrage adopte par le conseil de l'instruction publique, etc. Septieme Edition avec 473 Figures.'1 Paris. 1855. A Manual of Zoology, by M. Milne Edwards, Member of the •' Institut," adopted by the Council of Public Instruction of France. Translated by E. Knox, M.D., F.R.S.E., Lecturer on Anatomy, and Corresponding Member of the Imperial Academy of Medicine. Illustrated by 500 First-class Wood Engravings. London. 1856. There are three works which, taken together, form the elementary course of Natural History prescribed by the Council of Public Instruction in France : — one on Botany, by the grandson of the celebrated Jussieu ; one on Mineralogy and Geology, by Mons. Beudant ; and one on Zoology, by M. Milne Edwards. We purpose directing the attention of our readers to the last mentioned work, and to a translation of it by Dr. Knox, which has recently been published. The " Zoologie," in its original form, has already passed through seven editions ; and a letter from its learned author, addressed to Dr. Knox, states that above 30,000 copies have been sold. A sale so large as this is no bad criterion of the merits of the book. By it the public has testified its approval in the most unequivocal manner, and rendered eulogium on the part of a reviewer unnecessary. The first edition appeared in 1841. It had 572 pages, with 451 figures. The seventh edition was published in 1855, containing 584 pages, and 473 figures. In point of size, and in regard to the number of illustrations, the two editions are much alike, the principal difference consisting in some additional figures, and a few pages of letter-press added to that part of the book which treats of the Mammalia. We cannot but wish that a similar addition had been made to the portion devoted to the other extremity of the animal scale. The information there given is very scanty. Nine pages — and only nine — are occupied with one of the four great groups into which the animal world is divided — that to which M. Edwards gives the name " Zoophytes." Under this term he includes the Echinodermata, Acalepha, Polypes, Polygastric Infusoria, and Sponges. Yet within this humble group occur some of the most interesting phenomena which modern research has revealed, and others as yet but imperfectly seen, wherein the Naturalist has caught glimpses of a truth which he has been unable to seize. No one can be more fully aware of this than M. Edwards himself. Occupying the eminent position he does, and having access to the best sources of information, he must needs know what continental naturalists have been doing, and to I 60 t REVIEWS. k what extent their fellow-labourers in these kingdoms have aided in the onward progress of science. We must conclude, therefore, that M. Edwards has some good and sufficient reason for not treating more at length of those lower tribes ; and we can think of none so probable as an unwillingness to make much change in a book of which so many copies are in circulation. In all schools and colleges, inconvenience is felt both by teachers and stu- dents from discrepancies and differences in successive editions of the same work. To avoid causing such annoyance, M. Edwards possibly has allowed this part of the work to occupy now no greater space than it did fourteen years ago, when the lower invetebrate animals were comparatively but little regarded. It must not, however, be supposed that all evidence of progress has been suppressed. In some instances it has been indicated, though not fully dis- played, as, for example, the connection between the Medusas and the Ser- tularian zoophytes, opening up the debateable subject of the " alternation of generations." This receives an illustration from the Biphora, marine animals whose singular changes warrant the appellation happily bestowed upon them, when M. Edwards tells us " ces animaux bizarres sont assez com- muns dans la Me'diterranee." The affinity between the Polyzoa and the tunicated molluscs is distinctly expressed, and both are grouped together under the common term " Molluscoides." There are, however, cases in which statements, now known to be erro- neous, continue to be given, without even a foot-note to warn the reader of the changes in opinion which are consequent upon the advance of zoolo- gical knowledge. Thus, at page 569, we read of coral islands which appear to be based on the craters of extinct volcanoes. Yet Darwin had completed his voyage in the Beagle in 1836; he had communicated his observations on coral islands, and the true theory of their formation, to the Geological Society of London, in 1837; and Sir Charles Lyell, in his " Principles of Geology," seventh edition, published in 1840, had renounced the old hypothesis, adopting the satisfactory and philosophical explanation of Darwin. The first edition, therefore, of the " Cours Elementaire" con- tained on this point the idea still current, but even then known to be erro- neous, and this statement remains unchanged. We may adduce another example in corroboration of our remark. The figure of the Argonaut appears with the expanded sails, and the " tiers of oars on either side," according to poetic fable ; yet no information is given regarding the habits of the animal, and the important functions performed by the supposed sails ; and a doubt continues to be implied, if not expressed, MANUAL OF ZOOLOGY. . 61 as to the true builder and owner of the graceful shell (p. 553), years after all question on the matter has been set at rest by positive observation and experiment. While we think it right not to pass by unnoticed the omissions or defects of this excellent manual, we most cordially concede to M. Milne Edwards the rare honour of both advancing zoological knowledge by original re- search, and diffusing it by the production of an elementary work, which has been welcomed wherever it has appeared. In these countries it is well known to every naturalist, and its beautiful illustrations, by means of casts and electrotypes, supplied by the publisher, have been multiplied, and served as illustrations for other works of a similar kind. We are tempted to pause as we pass along, and meditate on the good that this small volume may be expected to accomplish. It is widely spread over France ; it has sailed along the Mediterranean, steamed on the Rhine, climbed the Pyrenees, and nestled in quiet valleys amid the Alps. In every place it has, doubtless, found some ardent inquirer, whose views have been rendered clearer, and whose progress has been aided by the lore gleaned from its pages. Who can venture to estimate the impetus given to the onward march of Zoology by the ardour of youthful recruits thus enrolled under her banner ? From the original work we now turn to the u Translation" recently published by Dr. Knox ; and we desire to know, in the first instance, in what spirit, and for what objects, it has been undertaken ? And, next, to what extent it has been successfully accomplished ? With regard to the first point, Dr. Knox has afforded us the requisite information, in the following words : — " Thinking it would be but an act of justice, though tardy, to place before the English reader a work of an esteemed friend, which, according to the fashion of the day, has formed the stock in trade of so many English, Scotch, Irish, and American literary contrabandists, I wrote M. Edwards on the subject, and received from him the following letter — a guarantee to the public that the translation has been undertaken with the author's full approbation." The letter is then given, and the following words are, we presume, to be regarded as the " guarantee" to which re- ference has just been made : — " II ne peut m' <3tre que tres agreable de voir paraitre sous vos auspices une traduction Anglaise de mon petit ouvrage elementaire de Zoologie." In the next paragraph of the prefatory notice Dr. Knox proceeds thus : " As a scientific man, and a teacher of Anatomy and of the great prin- G 62 REVIEWS. ciples of Zoology to thousands, including the names of many of the most celebrated scientific men of the day, I ought not, perhaps, to notice the literary pirates to whom I have just alluded, were it not that, during the last hundred years, they have, in despite of many excellent English writers, greatly retarded the progress of Zoology in Britain and elsewhere, where- ver, indeed, the English language is spoken." We at first thought that the " contrabandists" denounced in the first paragraph were the same as " the literary pirates" of the other, but as the latter have been at work for " the last hundred years," this cannot be the case. A general treatise, or a manual of Zoology, must, from its very na- ture, be to a great extent a compilation. That, however, is no reason for not acknowledging the sources whence the information is derived, and quoting the authorities for facts but recently made known by other writers. To do so seems to us to be an act of common honesty, and nothing more. On this point, therefore, we would most probably agree with Dr. Knox, though we might require additional evidence against the compilers before assenting to the verdict : " Their views are anti-scien- tific, anti-educational ; calculated, if not devised, to retard the progress of the human mind." Dr. Knox proceeds thus : — " A single remark is required, and will, I trust, suffice to explain why this translation of my esteemed friend's work occupies a considerably less space than the original. The translation being addressed to Englishmen, lovers of matters-of-fact in science as well as in other things, it became a duty I owed the public and publisher to avoid all repetitions, all French idioms, all lengthened treatment of physiological and metaphysical hypo- theses ; but in doing so I have scrupulously avoided omitting any fact or idea or opinion of the author. The curtailment has been in the language alone." In conclusion, he notices the " combinations of unclassical terms" which " have greatly retarded, no doubt, the accomplishment of that object which is the aim of this work — namely, the introduction in England of Zoology as a branch of primary education." It would appear from those words that Zoology had not yet been " in- troduced" into England as a branch of primary education. This announce- ment came upon us by surprise. We had seen, for years back, advertise- ments of books avowedly for the purpose of teaching the elements of Zoology to young people. We had understood that in many schools such books were regularly used ; and that the use of them was gradually ex- MANUAL OF ZOOLOGY. C3 tending. But as the remark might possibly be intended to apply to schools under the superintendence of Government, and supported in part from the public funds, we procured a list of the books supplied to schools by the Committee of Council on Education in England, and sought for such evi- dence as it might supply on the question. We found in the list books treating of Quadrupeds, of Birds, of Reptiles, of Fishes, of Shells, &c. ; Domesticated animals, Wild animals, and the justly popular work of the late Bishop of Norwich, " Familiar History of British Birds." We found also works of a wider range, as, the " Rudiments of Zoology," published by Messrs. Chambers ; " Elements of Natural History," by Mrs. Lee ; a Zoology written expressly for schools, by Gosse ; another by Patterson, &c. The books supplied by the Commissioners of National Education in Ire- land likewise afforded satisfactory evidence that the importance of Natural History as a branch of primary education was fully recognised. We learned also that it was, to some extent, a qualification for teachers, ai d formed a part of the examinations to which those of a certain standi ng were subjected. We must, therefore, suppose that Dr. Knox, at the time he wrote this paragraph, was not aware of what had been going on in these countries with reference to Zoology as a branch of school education. Dr. Knox has told us, in a passage already quoted, that he has pur- posely avoided " all French idioms." Yet the following phrases remind us strongly of their Gallic origin : — " Some (fishes) lead a sedentary life" — p. 351. "Strongest resemblance with those" — p. 449. "The narrow limits of these lectures do not permit us to consecrate at this moment more time to this subject" — p. 398. In the original the occurrence of warm weather is spoken of in connection with the metamorphosis of certain in- sects, the words employed being " si le temps est chaud" — p. 498 : in the translation, " if the time be warm" — p. 398. A more serious fault is, that the French terms are given when a very moderate amount of trouble would have enabled Dr. Knox to give a well known English word. Thus, we have " Manchat" instead of Penguin ; " Echasse d'Europe" for " Stilt ;" " Canard Macreuse" for the " Common Scoter," and " Butor" for " Bittern." All schoolboys are familiar with the appearance of the boat-fly and the whirl-gig ; yet they would scarcely know their old friends by the names Notonecte and Gyrin ; and if they read of M the Courtiliere, which does such mischief," they would assuredly feel puzzled, unless the figure made them understand that the mole cricket was the insect referred to. Some mistakes of the press have, unhappily, escaped correction, though 64 REVIEWS. they are very apparent. ►Thus, the specific term " pervonia" is applied (p. 405) both to the sirex and the butterfly, which are figured on that page. The printer of the French work has, at p. 240, given the figure of a breeze-fly, instead of that of the carpenter-bee. The error has been faithfully copied in the English translation : we are there presented with the nest of the carpenter-bee ; but the two-winged insect is figured as its builder, with the name " Xylocope" (carpenter-bee). Dr. Knox has introduced — either in the text, or as foot-notes — various extracts from, or references to, his own published works. There may be a difference of opinion whether the book has been improved or not by these additions. Into this question we do not propose to enter. We have examined the work merely as a translation, and are sorry to say that as such it does not do justice to the original, while it contains many blemishes which a little research, and a very moderate amount of revision, would have excluded. We doubt not that these amendments will be made accordingly ; and the volume will then be an useful auxiliary to other books treating of kindred subjects, which have been " introduced" years ago among our re- cognized school-books. The careful translation of any foreign work of emi- nence shall ever be regarded by us with favour ; and we hope to have many of them communicating to us the facts observed by our continental brethren, and the significance of those facts, as they appear to reflective and educated minds. R. P. Wahre Parthenogenesis bei Schmetterlingen und Bienev ein Beitrag zur Fortpflanzungsgeschichte der Thiere. Von C. Th. E. von Siebold. 8vo. Leipzig. 1856. On a true Parthenogenesis in Moths and Bees, a Contribution to the History of Reproduction in Animals. By C. Th. E. von Siebold ; translated by W. S. Dallas, F.L.S., &c. 8vo. Van Voorst. London. 1857. Professor Owen, the author of the term Parthenogenesis, has defined it as procreation without the immediate influence of the male. The examples given are spontaneous fission, gemmation, development from germ-cells and germ-masses, or from unimpregnated ova. The term has been readily adopted by other physiologists, and some have extended the application of it to the analogous phenomena in the vegetable kingdom. Siebold, on the other hand, proposes to confine it to the last-named of the above cases. PARTHENOGENESIS. 65 His objections to the original use of it, indeed, appear to rest partly on an untenable ground of etymology, partly on a misconception of Owen's views, which the distinct statement given by the latter should have pre- cluded. Owen, however, seems not indisposed to accept the limitation proposed, and suggests the term Metagenesis, for the sum of those changes which certain species undergo in the progress through successive indivi- duals from the ovum to the perfect [impregnating and] egg-producing form, or as it has been called the Alternation of generations. The term we have enclosed in brackets seems to be redundant, and might, in fact, invalidate the definition, according to the facts collected by Siebold in the little volume which we are here to notice. The result of these would seem to be, that the animal development from a perfect egg may take place without impregnation, 1° exceptionally ; — 2° normally, the law prevailing either partially, as subservient to definite purposes in the social economy of the species, or cyclically through a limited number of successive generations, or permanently and universally in regard to certain groups. The evidences which Siebold has here collected are not absolutely new, but they had partly been overlooked,* partly they seemed to demand that closer investigation, anatomical and historical, with which he has here supplied us, so that we are now in a condition to recognise a law of generation, of which the higher forms of animal life in the vertebrate classes have afforded no unequivocal example. Various statements have appeared from time to time of fertile eggs being laid by female Lepidoptera secluded from all access of the male. In some of these cases the progeny has been reared to the perfect state, and the experiment has even been continued through more than one generation in succession. Indeed, the published instances are so many, and the autho- rities so respectable, that the rather sceptical criticism which Siebold has applied to them might appear overstrained. It has led him, however, to institute fresh experiments, guarded with all the precautions the assurance of which he misses in the previous documents, and these have obliged him to admit the fact, in respect to the common silk worm, that the female moth is capable of laying fertile eggs without impregnation. The propor- tion of the eggs, however, which are capable of development in this case is small, and, generally, it would appear that a natural limit is set in this way to the propagation of the species in any but the ordinary mode of generation. A very peculiar mode of limitation is indicated by an experi- ment of Carlier, which Lacordaire has recorded in his Introduction. Three successive generations of Liparis dispar were produced by secluded QG REVIEWS. females, but the last brood consisted entirely of males. We are led at once to connect this observation with the normal mode of generation of the drones of the hive bee. But that which appears as exceptional in the history of some other Lepidoptera meets us as a regular provision of na- ture in the economy of various sac-bearers of the families Psychidae and Tineidse. Here the generations of wingless females succeed each other, without access or production of the winged male except at distant periods. How far these periods are subject to rule we have no satisfactory evidence, or that there is any decline of the vitalizing energy of the female organiza- tion in the course of generations. In the Psyche helix, as observed by Siebold, the females alone have occurred during seven successive years, and the male insect does not appear to be known with any certainty, if that sex exist in nature. For here we may be approaching to the most complete exemplification of Parthenogenesis, exhibited in the case of cer- tain groups of insects, where the species is constituted, solely and at all periods, by females producing perfect eggs, and undistinguished, as it seems, by any visible peculiarity either of redundancy or defect in the reproduc- tive organs. This is the case in all the true Gall-flies, — the genus Cynips as restricted in recent times, — and a few more (Biorrhiza, &c), while the rest of that family, and even genera approaching the gall-flies so closely in structure and economy as the genus Teras for example, present both sexes, and the males usually even in the greater numbers. This perfect type of Parthenogenesis is, probably, not limited to the class of Insects, as there is evidence of its prevalence in certain Entomostraca, at least. No form of Parthenogenesis, however, seems more remarkable or in- structive than that which is present in connection with the economy of the common honey-bee. Many strange mistakes have prevailed from early times as to the history of the perfect societies of these insects, ruled by laws of instinct which have stimulated the curiosity of man, as much as their productive industry has served his uses and attracted his observation. But it has been only at a comparatively recent period that the true charac- ters of the sexes have been anatomically fixed ; and these discoveries have not yet succeeded in dispelling, among the practical bee-keepers in general, either inveterate errors or wild conjectures. Yet it is to one of this class, Dzierzon, pastor of Caiismarkt, in Silesia, that science ultimately owes the discovery of the true physiological relations which rule the generation of the race. The main facts are these : — the Queen bee, or perfect female, before impregnation lays eggs which produce Males only. After impregna- tion, which takes place but once in the course of her life time, the eggs pro- PARTHENOGENESIS. 67 duce male or female larvae according to the sort of cells in which they are laid. By a delicate and difficult microscopical examination Siebold has proved that the eggs laid in the queens' and workers' cells have been pene- trated by one or more Zoosperms, which, on the other hand, are never found in the eggs deposited in drone cells. He concludes, with reason, that the access of the impregnating fluid contained in the receptacle is cut off at pleasure by an instinctive act of the female in oviposition. The worker- bees, or females with undeveloped organs of generation, being incapable of impregnation, in the rare cases in which their ovaries are sufficiently deve- loped to mature a few eggs, these produce only male brood. We have not space to do more than allude to various other interesting topics which Siebold has linked to these inquiries ; the improved bee- hives of Dzierzon, which allow every single comb to be removed at plea- sure, inspected, and replaced ; the advantages arising from the introduction into Germany of the Italian variety of the honey-bee, Apis ligustica, and the results of the intermixture of the two races, as bearing on the immediate subject of the essay ; as also the curious spiral cases of some Lepidopterous and Neuropterous larvse represented in the plate, certain of which have figured as shells in some recent treatises on Mollusca; the illusory likeness being heightened, in this instance, by a sort of operculum, with which the inmate, a Phryganidan, (Helicopsyche Siebold,) closes the aperture of its case, before entering on its state of repose as a pupa. The translation by Mr. Dallas acquires additional value from the notes by Professor Owen inserted in it, especially those which recall attention to the instances in which that truly wonderful man, John Hunter, has again anticipated the discoveries of modern Physiologists in their own special branches of research. The translation is made with great care and scru- pulous fidelity. A sentence or two only have been omitted, which were unnecessary in the context, or seemed out of place. In a very few instances we think there is an alteration slightly affecting the sense. Thus, for example, page 12 — Bombyces for Sjnders ; page 16 — Scheven does not mean that the specimen he had is figured by Roesel, but has cited the figure merely to determine the species ; page 17 — the prolixity of Scheven is by no means commended, as the translation conveys ; page 21 — the import and value of Blancard and Audebert's observations is very differently characterised in the original ; page 24 — it is not by means of the laying-tube, which has a different office attributed to it, but by the feet, that the female Fumea clings to the sac, as expressly stated in the original concerning this and Solenobia a little further on, but omitted in the English, 68 REVIEWS. page 25. Again, in the following page, Siebold by no means asserts, as is implied in the translation, that the life of the female is shortened when impregnation does not take place — a statement which is at variance with the general result of observations on insects. Page 28 — the sac of Psyche helix is described as having one whorl more than is correct, which the figure, as well as the original text shows clearly enough ; page 40, near the foot — stock should be hive, &c. These criticisms are, indeed, so minute that we should scarcely have particularized them, were it not that the interest in the subject, awakened by the appearance of this translation into English, insures for it a large circu- lation, as it deserves ; and as that may, and we hope will, lead to further original investigations and fresh evidence of the law propounded, it would not be well to have any pains wasted in controverting particular state- ments with which the author is not, in fact, concerned. A. H. H. The Marine Botanist ; an Introduction to the Study of the British Seaweeds, containing descriptions of all the Species, and the best methods of preserving them. By Isabella Gifford. Third Edition. London : Longman and Co. This third edition of Miss Gifford's introduction to marine botany is so much enlarged and in every way improved as to deserve to be looked on as a new work. A number of additional plates have been added, and an introductory chapter ; while the systematic portion of the volume has been rendered more valuable by fuller and more accurate descriptions, by additional habitats of some of the rarer species, and by short notices of certain little known species not likely to fall in the way of ordinary col- lectors. The book, in its present form, will be acceptable to many young collectors and amateurs who might be deterred from the study by more formal treatises, and, equally with Dr. Landsborough's little volume, will serve as a familiar introduction to the subject. It is very portable, written generally in a clear style, and sufficiently systematic to answer the pur- poses of system, without being overburdened with technical terms. We heartily wish it the success which it so well merits. W. H. H. GENERAL ZOOLOGY. 69 * Zoonomische Briefe : Allgemeine Darstellung der thierischen Organi- zation. Von Dr. Hermann Burmeister, Professor der Zoologie zu Halle. Erster und Zweiter Theil. 8vo. Otto Wigand: Leipzig. 1856. Not addressed directly to the professed Zoologist, these outlines of the chief types of animal structure, and of the relation that they bear to the general system of nature, are intended for a class — even now increasing in number — who, prepared already by a certain amount of education, have come to regard the observation of nature as a part of the habitual exer- cise which conduces to the full development of the faculties, and are willing to include the study of the laws of Life and Organization among the acknowledged instruments of intellectual training. As to the epistolary form into which they have been thrown, this appears to have scarcely any object but that of interrupting the long-drawn chain of systematic analysis by convenient pauses, and, perhaps, of occasionally relieving the monotony of comparative descriptions, by falling into a tone more colloquial than might have appeared to suit a formal lecture or a scientific essay. But the work does not assume, or affect, the anecdotical character of some books that are termed popular, by courtesy, we suppose, on the strength of being only superficial. The writer's thorough acquaintance with his subject, at once minute and comprehensive, his genuine — even passionate love of nature, and his eminently happy style of painting in words, have qualified him, without renouncing a scientific treatment of his materials, to make out of them two very pleasant volumes, for those, at least, in whom a taste for the exact observation of nature has been in some degree awakened, and who do not feel it a painful stretch when they are obliged to concen- trate their attention, and to reflect and compare, as well as perceive and remember. The author's design, not less than the compass of the work, has ex- cluded, for the most part, those circumstantial examples among which popular books of Natural History delight to revel ; but these have not been superseded for the sake of introducing some questionable speculations, or investigations of a difficult and slippery sort. If elsewhere Burmeister, in the pursuit of a natural classification, may have appeared sometimes to attach undue importance to the earlier stages of structural development, in comparison with the finished type to which, in every instance, they may be viewed as continually tending ; yet here, at least, his riper judgment and experience has revolted against the fixed ideas of some extreme de- votees of Embryological study ; and he appeals from their verdict, who H 70 JKEWEW3. can see nothing in animated "nature more profoundly significant than their " ciliary epithelium" and the "segmentation process." Whatever may be thought of the freaks of fancy that some of its votaries have indulged in, however we may reprobate the perversions of truth and common sense which have been engrafted on it in certain quarters, this much is fairly to be said of the Transcendental school of Natural History, that its original principles were calculated to suggest, to a reverential spirit, some of the most striking arguments which Natural Theology has to offer for the infinite wisdom and universal agency of one God. Nay, they seem to be such as can scarcely fail to excite some notions of this sort in any unprejudiced mind, even when the distinct acknowledgment of that presiding intelligence is most studiously eschewed by the teachers of natural science, and although " God," " Creation," and " Providence" be set aside for such equivocal terms as " Nature," u Law," or " Necessity." It might appear, too, as if the systematic part of Natural History were thus placed on a more unalterable base, in being referred to certain principles exterior to and independent of the modes of operation of the human intellect ; as a mere artificial instrument of which classification has sometimes been regarded. It is all the more surprising to find Bur- meister, who has laboured before so hard, and, as many may think, so successfully — whatever he himself may judge of it now — to establish a natural classification on philosophical grounds, in the present work almost giving up the objective truth of natural groups in zoology, while he retains them for a method of exposition. " The only real existence is the lowest and last division, called Species ; this alone can be seen, felt, caught, exhibited in collections; — all the other superior groups are mere con- ceptions, framed according to the agreement of certain characters, but of which the real existence must be denied. There exists neither Bird nor Fish, but only a Sparrow, a Crow, a Hen ; or a Carp, a Pike, a Herring, &c. — the first three are Birds, the others Fishes, but none of them a mere Bird, or a mere Fish." The fallacy here is so palpable that it is hard to com- prehend how it could for a moment have imposed upon a philosopher like Burmeister. The argument — if it is good for anything, and not a mere play upon words — goes equally to negative the real existence of species. After he had said, a little way back, that in an army the individual soldier alone has a real existence, why not affirm that individual animals alone exist, and not species — that no one is a mere man, but also John, or James, &c that is, distinguished by some marks — be they but particular existence in a definite portion of space and time — from every other man. It is clear that GENERAL ZOOLOGY. 71 he has mystified himself by an equivocal use of the term, " real existence." He proceeds — u Such conceptions, which have no real existence, but can be defined ideally by a certain collection of characters, are called Types of Animal Organization. Accordingly, we speak of the types of Genus, Family, Class, &c, and we endeavour to discover by observation the essen- tial properties of each, and to express them in words. These words con- stitute the character of the group ; they convey the definition of the idea, and contain the marks by which the type may be known, and which, there- fore, are considered as typical of the group." This, we see, is in allusion to, but not quite in accordance with, the doctrine of Linnaeus, that the character does not make the genus, but the converse. That very real existence of species, to which Burmeister yet clings — as it seems, however, not without a wavering faith even as to this — as the last floating straw of a drowning system^ is just as truly an abstraction of the mind as any of the higher groups. Define it as we will, the idea of species comprehends some relation which cannot be seen, felt, or exhibited corporeally — such as that of continuous generation from one stock ; or, if we admit that no irre- fragable proof has yet been adduced of the necessary descent of all the individuals of a species from one original pan-, or parent, then our idea of species must differ still less in kind from that of any higher group. We must be able to conceive, as possible at least, if we do not actually assume as true, the original existence of several individuals and one species, to which they are subordinated not by that peculiar relation of Generation, but by other agreements, of the same sort, and only greater, in number or degree, than, those we recognize among the higher groups, and in the one case as in the other, coupled with Differences ; — whether these be Specific, Generic, or simply Individual, does not materially affect the pre- sent question. In this case, whether we trace these correspondences up to Creative Design, or view them simply in reference to our own Modes of Perception, the result is equally that those Relations and Agreements, and, consequently, also^ the Groups connoted, or denoted, by the character, have a Real existence as truly in the Higher (genus, &c), as in the Lower (species) — yet not Lowest group so long as some individuals of the Species present fewer differences and more points of agreement among themselves (Races, Varieties, &c), than others. Again, whatever be our Idea of " Species" abstractedly, the Character of any particular species is a collec- tion of marks of a precisely similar nature with those which make up the character of a Genus, or any higher group, differing only in being more numerous and particular, inasmuch as the character of the Species includes 72 REVIEWS. the complete character of the Genus, and of every higher group, in direct ascending Series, and something more. In Direct ascending Series — we repeat — for the Character of some genus, in another, i.e. Collateral series, may embrace more numerous marks than that of a Species not subordinate to it. Practically, too, it is the character that determines the idea of the species, which is then of the same sort as that of genus, &c, and applied in the same way, so that it is hard to tell why the one should be said to have a real existence more than the other. It is, of course, only in one point of view that Burmeister disputes the existence of Natural groups. That there are natural groups, according to the perceptions of our own minds, seems to need no further proof than the universal method of human language (admissible evidence in a question of this nature), and the fact of our being able to make any true general pro- positions concerning the things we observe in nature, of such a sort as form the basis of Burmeister's own graphic sketches, which, if sufficiently divested of technical affectation to be both attractive and intelligible to all who have availed themselves of the advantages of a liberal education, are, at the same time, imbued with such intrinsic learning, that the most advanced need not disdain to study them, for the sake of their own proficiency as well as delight. We fear our readers will think we have been prolix in this dry discussion of the point on which we have ventured formally to dissent from the view that Burmeister has taken here. We find a much more agreeable employ- ment in turning to the body of the work, to which we can offer the meed of almost unqualified commendation. The matter here is too condensed — the phrase too pregnant — to admit of further abridgment for the purpose of a review. As a specimen of the author's manner, we extract the concluding section of the history of the Polyps : — " The study of the formation of corals at the epochs anterior to history, or, if another form of expression is preferred, in pre-Adamitic times, is a subject of the deepest interest for the geologist. It shows him the won- derful activity of these minute creatures on the largest scale, while it proves the complete agreement of organization between the most ancient Polyps and those in being at the present time. In all periods, going back to the most remote antiquity of the globe, there have been Polyps in our terrestrial seas, at least as long as organic life has existed on the earth at all. It is corals that furnish the most ancient evidence that the earth was inhabited long before the beasts came into existence. The organization of these primitive corals agrees completely with those now living. We meet, indeed, GENERAL ZOOLOGY. 73 in the oldest strata, with genera distinct from, yet closely resembling, those of the present day ; but even at that period all the existing families were represented. In general the oldest forms of corals appear as flatter, lower, more solid stems, inhabiting the bare rocky coasts, in that period before a strand was formed, where they multiplied to a vast extent ; but in conse- quence of the disconnected form of the rocks to which they were affixed, they formed, as we see, no such great mural reefs as in later times, when the unbroken lines of coast descending sheer into the sea, with a rocky bottom, afforded a more suitable foundation to build up their stony walls. Certain members, however, of the oldest Silurian Calcareous rocks — as the lime- stone of Dudley, Schonen, Reval, Eifel (at Bensberg in particular) — seem to be chiefly formations of coral, which, if not constructed quite as solid reefs, are yet principally composed of the fragments of polypidoms. It is remarkable that the shells of the Polythalamia, so abundant in recent times, are almost entirely wanting in the most ancient coralline limestones. The most probable explanation is the absence of flat coasts at that remote date ; since the Foraminifera occur only in such situations, and at the present day inhabit in the greatest numbers the lagoons of the coral islands, or the channel between the reefs and the land to which they form a barrier. There do not seem at that early period to have been any shallows of this sort." " The coral formation shows itself in uncommon plenitude in the calcareous rocks which constitute the base of the Carboniferous system. The Moun- tain limestone, as well as the Dudley limestone, is at least partially, a vast coral bank, to the formation of which the calcareous shells of Foraminifera have largely contributed." " Similar phenomena continue to occur in the calcareous formations of later date, almost all the sedimentary rocks of this class presenting local evidences of ancient coral formations, being composed chiefly of the stems and not of mere debris of corals. We may cite, for instance, the remark- able Dolomites of Lubenstein and Altenstein, Konitz and Posneck, at the south-western extremity of the Thuringian forest, not far from Salzungen, which are standing yet unmistakeable rocks of coral, the reefs that once bordered the narrow island ridge of that district, like those of the south- west coast of New Caledonia at the present day. This is another evidence that the former temperature of those seas was much higher than that now prevailing in the Temperate Zone; as the coral animalcules cannot live below 20°-23° of heat by Keaumur's scale. None but warm seas have 74 REVIEWS. coral reefs, and even there only in particular situations favourable to their formation." " The extensive system, denominated the Muschel-Kalk, is singularly characterized by the scarcity of its corals ; in no portion of it is there any unequivocal evidence of the existence of coral reefs. This formation seems to have been a purely sedimentary deposit, the organic fossils of which belong chiefly to the class Mollusca, as the name itself (shell lime- stone) indicates." " The coral banks of the Jura are developed in inverse proportion to this last. No other formation affords such decisive evidence of the effective part which the coral animals have taken in the formation of the upper strata of the globe. The members of this group, in their protracted parallel layers and defined terraces, exhibit, in unaltered position, walls of rock built up entirely of coral, and, at the foot of these, huge masses of coral debris which have been cemented by finely comminuted particles of lime, telling of the raging surf that broke against those reefs in days of old. These fragments are intermixed with other fossil remains varying with the localities, and form united a motley conglomerate, which is known under various names, but most commonly as Coral Breccia. Generally, the coral reefs of the Jura have more the character of Barrier reefs, and they seem to have extended parallel to the coast at a moderate distance from it, as exemplified in the coral reef of New Caledonia. Such a reef extended, during the Jurassic period, right through the south of Germany and the west of Switzerland, from the neighbourhood of Geneva away to Ratisbon, and thence northwards to the river Main, between Bamberg and Baireuth." "Not less extended was the system of coral reefs in the succeeding Cretacean period, the greatest part of the chalk being derived from corals, at least as a deposit. In the chalk period there existed already large land-locked seas, such as the Red Sea at present ; and on the shores of these the coral animalcules wrought in undisturbed tranquillity, and in concert with innumerable Polythalamia, deposited the whole mass of the white chalk, which is more than five hundred feet in thickness. The effective part which the Polythalamia have had, ever since, in the formation of the calcareous rocks, shows that flat tracts of coast have prevailed exten- sively. We have compared the terraces of the Jura to Barrier reefs, in the chalk we find more resemblance to the Lagoon reefs (" Atolls") ; although the chalk basins were not, strictly speaking, Lagoon islands, but GENERAL ZOOLOGY. 75 rather were formed as promontories of pre-existing higher lands, con- tiguous to great bays of the ocean." " Subsequent to this period, the formation of coral reefs took place only in particular localities, as we find it at the present day. The Tertiary period presents no more vast calcareous formations of coral purely ; the function of the coral animals in depositing lime has become more of a local nature, confined to some favourable situations ; while the secretion of lime by the Polythalamia, an agency which was wholly unknown at the earliest epoch, assumes a more and more predominant influence in the formation of the surface of the globe, as we approach the present times. The Nummulite limestone of the Mediterranean beach, the Calcaire Grossier of the Paris basin, the Molasse of Switzerland, and the sub-Appenine limestones, are composed almost entirely of the shells of these minute, but tough creatures, whose indefatigable industry has furnished one of the best and most important of building materials for the use of man. Almost the whole of Paris is con- structed of the shells of Foraminifera, and the material of the Egyptian pyramids themselves is a limestone, accumulated ages ago, of countless millions of Nummulites." " I have now, my friend, set before you, as I consider, the most essential and interesting facts in the Natural History of the Polyps ; but you may still be curious to know on what the little creatures live, as this has not been mentioned yet, although their alimentary organs have been described before. There can be no doubt that their chief food consists of living animals, and that the Polyps, in general, swallow these whole, having drawn them within their reach by means of the current created in the water by their cilia, or having caught and benumbed them with their sting- ing lines. This may be easily verified in the freshwater Hydra. The stomach, in most of the marine Polyps, is generally found empty, and seldom filled with any large bodies. They must be able to endure long abstinence, and content with small particles of food. What means, indeed, have they to master the larger animalcules ? The current which they create, their chief means of obtaining aliment, is too feeble to overpower those of any bulk, neither are their tentacles long enough to reach and envelope such. Vegetable matter does not seem to enter into their alimen- tary cavity, probably because it is not fit for their sustenance. There are, indeed, plants floating freely in the sea, but this only in a few situations, and these are far too bulky to be swallowed by a Polyp, while it has no organs with which to detach from them smaller portions. A Polyp cannot 76 REVIEWS. gnaw, but is obliged to wait till a piece comes adapted to his swallow ; and that is much more likely to be an active moving animalcule than an alga spore, the only vegetable substance to be had in any quantity in the sea. I think we may safely conclude, therefore, that the food of all Polyps con- sists chiefly of living animals of no considerable size, and that, in particular, the small and partly even microscopical Tunicata, the fry of Mollusca, the minute marine Annelids and Crustacea which illuminate the surface of the ocean by night with innumerable sparkles of phosphorescent splendour, con- stitute the principal substances which the Polyps assimilate for their suste- nance and growth." The arrangement of the Animal world, which Burmeister follows in the present work, is, in a great measure, an amplification, and a more scientific filling up of the sketch which forms the concluding portion of his " History of the Creation," in the shape it wears in the latest edition. In the main, he has not departed from the principles of the classification proposed, a quarter of a century since, in his " Class-book of Natural History," and which was exhibited more at large in the " Manual of Natural History," 1837. The investigations of late years, so diligently pursued, and with such fruitful results, regarding the structure and history of the lowest classes of animals, it is true, have afforded much new materials, of which he has not been slow to avail himself here ; but this has tended rather to complete what remained imperfect, and to elucidate that which was obscure heretofore, than to effect a revolution in the ground plan of the system generally. Accordingly, we find the Bryozoa still ranked among his Polyps, yet not without a distinct acknowledgment of the tendency among them to bilateral symmetry, which, with certain other characters, has induced some of the most accomplished zoologists of the present day to place them rather in the Molluscan series, and next to the Tunicata. The Rotifera are still arranged under Crustacea, and the Myriapoda continue associated with the Arachnida. The Polypi and the Acalepha, among the Regular animals, are treated with much particularity and some apparent predilection ; all these, as well as the Irregular animals, in the first of these two volumes. The Symmetrical animals commence with the second volume. For the specialities in the class Mollusca, Burmeister has availed himself of the able assistance of his former pupil, Dr. Giebel. The classification of the Worms is, perhaps, the portion of the work which is stamped most strongly with originality. Commencing, as is usual, with the intestinal worms (Helminthes), the most simple of the class in their organization, Burmeister adopts the conclusions of Lieberkuhn, assigning GENERAL ZOOLOGY. 77 a place, the lowest, among them, to certain Unicellular animals (Mono- cystis, &c.) ; the Gregarince following next, — while he disposes of the Psorospermia in a somewhat different way, as merely embryo forms of these. With the Trematodes and Planarise the Leeches also are asso- ciated in one order (Platodes), Flat worms. The Round worms (Gymno- dermi) include the families Siphunculini, Priapulidae, and Echiuridse, — all comprehended under the common appellation of Mud worms (Gephyrei), — as well as the proper Nematodes. In the remaining order, Annelides, Burmeister's divisions do not vary materially from the views of Grube, except as regards the removal of the Leeches from this order by the former. The two volumes published bring us as far as to the end of the Arachnida. There remain, then, of Arthropoda the entire vast class Insecta, and the sub-kingdom Vertebrata, for the subject matter of another volume. Burmeister has briefly indicated here the mode of treatment he contemplates in regard to these ; the space reserved for the Insects being very strictly limited, in consideration of the length at which he has handled them already in other works devoted to that class specifically. The promised appearance of the concluding volume is postponed, however, until the author's return from the second travels, which he has newly under- taken, in South America. We will not here anticipate the criticisms we may be again obliged to enter into, when Burmeister shall have reached the culminant point in the scale of animal organization, at the deferred conclusion of the " Zoonomic Letters f for he has betrayed, of late, a wavering in his allegiance to the views he had embraced before, in common with all the most eminent names in Zoological science, touching another doctrine of not less interest than that agitated in the earlier letters, and on which we have already remarked. Bather let us wish him, on his distant pilgrimage, health and the bland favour of propitious elements ; along with which, large gatherings of scientific fruit, for the materials of future instruction and entertainment of many readers, and ourselves included. A. H. H. Manual of the Botany of the Northern United States. By Asa Gray, Fisher Professor of Natural History in Harvard University. Second Edition. New York. 1856. This work, designed for the use of students and practical botanists in the United States, will be found very useful to all persons in this country who may have received collections of dried plants from transatlantic friends or I 78 REVIEWS. relatives, or who may cultivate North American shrubs or flowering plants. It forms a complete flora of all the northern states east of the Mississippi, and includes, to the south, the extensive territories of Virginia and Kentucky. M This southern boundary," its author tells us, " coincides better than any other geographical line with the natural division between the cooler temperate and the warm-temperate vegetation of the United States ; very few characteristically southern plants occurring north of it, and those only in the low coast of Virginia, in the Dismal Swamp, &c. Our western limit, also, while it includes a considerable prairie vegetation, excludes nearly all the plants peculiar to the great western woodless plains which approach our borders in Iowa and Missouri. Our northern boundary, being that of the United States, varies through about five degrees of latitude, and nearly embraces Canada proper on the east and on the west ; so that nearly all the plants of Canada East on this side of the St. Lawrence, as well as of the deep peninsula of Canada West, will be found described in this volume." The number of species described is 2,928, divided as follows : — Dicoty- ledons, 1,713 ; Monocotyledons, 638 ; Ferns and Filicoids, 75 ; Mosses and Hepaticse, 502. The remaining Cryptogamous orders are omitted. The descriptions, without being needlessly prolix, are sufficiently full to enable a student readily to ascertain the name of a species ; and he is further assisted by the arrangement of the type — the most important or striking feature of each species being italicised, in the manner now so frequently and so use- fully introduced into local floras. Synoptic tables of the genera are given under each natural order, by which means the labour of ascertaining the genus to which a plant belongs is greatly lessened ; and, for the use of young botanists, an artificial key to the natural orders is prefixed. The genera of the Cryptogamia are ably illustrated in fourteen excellent litho- graph plates — a most important aid to the student unacquainted with the systematic arrangement of these tribes. The descriptions of the Mosses and Hepaticae are from the pen of Mr. Sullivant, one of the ablest of living muscologists, " who has," says Dr. Gray, " included in this edition all the species of Musci and Hepaticce known to him as natives of any part of the United States east of the Mississippi, and has sedulously elaborated the whole anew; not only laying a broad foundation for a knowledge of North American Muscology, but furnishing botanical students with facilities for the study of these two beautiful families of plants, such as have never before anywhere been afforded in a book of this kind." We cordially endorse this well-deserved encomium. It is needless to speak of the manner in which Dr. Gray has executed BOTANY OF THE UNITED STATES. 79 his own part of the book. Like all his other works, it shows the combi- nation of skill in treating his subject with perfect familiarity with the details. No living botanist is so competent to describe the plants of North America ; and no one has done more than he to illustrate the flora of his country ; nor is any one so unceasingly at work, and few so prolific with the pen. Would that we could add that all the works of our excellent friend were brought to a like happy terminus as the present ; and, specially, that the " Flora of North America" (Torrey and Gray) were among the num- ber. To the deep regret of all botanists, that invaluable work, commenced in 1838, after reaching Composite in 1843, seems to have been cushioned by its authors for the last thirteen years. W.H.H. Preliminary Notices of the Invertebrate Animals collected in the United States Expedition under Captain John Rodgers to the Southern Pacific Ocean. By W. Stimpson. Part I. (From the Proceedings of the Academy of Natural Sciences of Philadelphia, February, 1857.) In the twelve pages before us we have, printed in small brevier type, a list of all the species of the Turbellaria Dendroccela, which were taken in the South Pacific Expedition sent out by the United States. This class of animals is very nearly allied to the Annelida ; in fact, the one class merges into the other by almost insensible gradations. We have but few representatives of it in our British Isles, but the common Elasmodes (Planaria) flexilis will serve as a good example. Mr. Stimpson applies the name Dendroccela to the whole tribe, in this following Diesing. He also divides it into two sub-tribes, Digonopora and Monogonopora. Ap- pended to the list of species found we have descriptions of fifty-two new ones ; many of them, we remark, taken " in portu, Hong Kong." The genus Planaria Mull, is placed under the sub-tribe Monogonopora (apertura genitalis unica), whereas the Planaria of Dalyell, Gosse, and others, repre- sented by flexilis, stagnalis, &c, is merged into the genus Elasmodes of LeConte, and placed under the sub-tribe Digonopora (aperturae genitales dua3. We trust that we shall have the pleasure of noticing the various parts of these most valuable Notices as they appear, and that when com- plete we may be able to give our readers a critical review of them. The author proves himself to be quite conversant with all our lately published British works on this subject ; and we might, in conclusion, notice that the Leptoplana tremellaris of Oersted is not thought by him to be identical with 80 REVIEWS. the species figured in Gosse's Marine Zoology, Pt. I., fig. 125. This we are not surprised at, as even with the aid of Oersted's Plattwlirmer, — an admirable monograph as it is, — it is a most difficult task to identify the species of the genera of this order. Flora Vectensis ; being a systematic description of the Phasnogamous or flowering Plants and Ferns indigenous to the Isle of Wight. By the late Wm. Arnold Bromfield, M.D., &c. Edited by Sir W. J. Hooker M.D., &c. From the early days of Johnson's " Itinera in agrum Cantianum," published in 1629-1632, down to the present time, it has been a favourite practice of British botanists to illustrate the vegetation of particular provinces or counties, or even of isolated parishes, by writing special treatises on the plants indigenous to them. The value of these district floras has been generally admitted, and one after another has been hailed with interest by the public, until at last it may be said that no country possesses an equal number of such useful guides to the young botanist as England, notwith- standing that there is much still to be done. We have our local floras of Devonshire, of Shropshire, of the Malvern Hills, of Charnwood Forest, of Yorkshire, of Poole, of Liverpool, of East Kent, of the Channel Islands, of Keigate, Surrey ; of Bath, of Oxfordshire, and many of the English dis- tricts ; of Edinburgh, of Glasgow, of Lanarkshire, of the Hebrides, and others in Scotland ; and though district floras are yet nearly desiderata in Ireland, we may at least mention two floras of the whole island, and a sketch of the flora of Cork as a good commencement. Hitherto, no ade- quate account of the vegetation of the Isle of Wight has been published, and this is the more remarkable as there are few places more visited by summer tourists, or so accessible from the metropolis, or that afford within a moderate and strictly defined limit a more interesting field for the botanical student. Situated on the southern coast, and diversified by hill and dale, and with a considerably complex geological structure for so small an island, it enjoys many privileges as a botanical province in miniature. The work before us is, unfortunately, a posthumous one. It had been long in preparation by its accomplished author ; but he was not spared to complete it on the original design, and it is, therefore, notwithstanding the care of the editors, but a fragment. Very properly, as we think, the editors have preserved it as nearly as possible in the state in which it was left, merely inserting between inverted commas and brackets such matter as was abso- FLORA OF THE ISLE OF WIGHT. 81 lutely required to fill up the blanks in the descriptions. The author's design in undertaking it is thus described in the editorial preface : — " Dr. Bromfield became resident at Ryde, in the Isle of Wight, in the year 1830, and shortly afterwards conceived the idea of preparing a Flora of the Island. He was not content to follow the usual practice in the making of local Floras and Faunas, and to be satisfied by merely presenting a tolerably full list ; but he determined that the investigation should be very complete, and that every species should receive an original description. Nor was he satisfied with a mere cursory research in the framing of these descriptions, or with copying any cha- racter from other authors unverified by his own examinations. He was also equally careful to avoid describing general characters from individuals or varie- ties, and endeavoured with immense and most persevering care to select such points as are really the permanent and essential characters of genera and species. To ensure this result he was in the habit of obtaining a very great number of specimens of each species, collected from various localities; and, whenever {>racticable, he endeavoured to compare Isle of Wight specimens with those col- ected at a distance. Having thus secured sufficient material for investigation, his next aim was to consult every author within his reach for all the characters which different observers had noticed. For this part of his plans he had collected a very ample botanical library, especially of foreign authors. The characters, however, observed by others were, for his own descriptions, merely suggestive, none being recorded but such as, after careful examination, he himself found to exist in nature. The results of these careful investigations were the most accu- rate and elaborate descriptions that can be well imagined ; but such were the time and labour bestowed on each species — as much as many authors would give to a genus or family — that this circumstance very materially retarded the pro- gress of the work." It is a thousand pities that a design so well devised and so ably com- menced should have been left incomplete. The usual fault of the writers of local floras is, that their attention is so concentrated on the plants of their own little district that they neglect the examination of kindred types from distant localities, and so they are frequently induced to multiply false species, by giving specific value to characters that depend on modifications of soil or of climate. Dr. Bromfield took special pains to avoid this error Indeed, in his many journeys, for he travelled extensively in America and Europe (and at length ended his days in Syria), he must have seen the same species putting on many forms, according to the locality in which it grew ; and would thus be prepared for that careful enquiry into the value of specific differences which his writings display. The detailed descrip- tions of species, so far as they were finished, are models of careful descrip- tion, and will be found well worth the study of the descriptive botanist. The localities recorded under each species are, as might be expected, very full; a topographical index to all the "villages, farms, seats, woods, &c, mentioned as stations for plants, with their bearings and distance from the nearest market town or place of note," concludes the volume, and a large and carefully executed folding map of the island, mounted on linen and furnished with a stout cover, accompanies the work. OZ REVIEWS. In a brief introduction of 14 pages, the climatical and geographical con- ditions of the island are summed up, and a sketch given of the general character and distribution of productions. We could have wished this chapter had been extended. The opening sentences, which are as follows, will serve as a sample of the author's manner and matter. 11 From the situation of the Isle of Wight on the southern boundary line of the agricultural zone of Watson, we everywhere recognise the appropriate features of the latter in the general aspect of vegetation, whether native or introduced. We find the cultivation of wheat predominating over that of all other grain, and producing as plentiful returns on the exposed crests of the loftiest cliffs, or within a few yards of the sea beach, as in the sheltered vallies of the interior. The Vine and the Fig are common, even in the cottager's garden, the latter always, as a standard, bearing abundant and luscious fruit ; whilst, in addition to the more ordinary orchard trees, the Quince, Walnut, and Mulberry ripen per- fectly, and produce plentiful crops. Both the narrow and broad-leaved varieties of the Myrtle (Myrtus communis) form stout bushes in the open air, and mature their fruit in many places, even on the north side of the island and in the cold soil of Ryde, suffering in very severe winters only, and are then seldom more than partially killed back in exposed situations, as many very old and vigorous trunks attest in various places. The sweet Bay (Laurus nobilis) attains the dimensions of a tree, and ripens its berries in abundance, resisting our severest frosts, as does the Laurustinus, which gives to our gardens and shrubberies at mid-winter the verdure and bloom of summer, tbough its fruit is more sparingly perfected. The Strawberry tree (Arbutus unedo) is equally common and hardy with the two last, fruits pretty freely, and grows to a tree of respectable size, though inferior to the timber-like dimensions it acquires on its native rocks in the S. W. of Ireland, or even in the S. Western counties of England, where the greater moisture of the atmosphere eminently favours the development of this, as of most other evergreens. But if the greater cold of our climate in winter, and the greater dryness at all seasons, tend to check the growth of these and other sempervirent plants, the comparative absence of humidity and a less clouded sky enables the increased heat of summer to ripen the wood, and so fit it to endure a degree of frost it would else be unable to withstand. So happily balanced, in the climate of the Isle of Wight, are the vicissitudes of heat and cold to which it is occasionally subject from its proximity to the mainland and to the continent of Europe, in a degree unusual to insular situations, that the for- mer repairs, or rather counteracts, the destructive agency of the latter in vege- tation." A lithographed portrait of the author is prefixed to the volume, which contains 678 closely printed pages, besides XXXV. of preface and intro- duction. W. H. H. The Testimony of the Rocks ; or, Geology in its bearings on the two Theologies, Natural and Revealed. By Hugh Miller, Author of " The Old Red Sandstone," &c. Edinburgh : Thomas Constable and Co. 1857. It would be difficult for any reader, even slightly acquainted with the cir- cumstances attending the appearance of the work now open before us — posthumous as it is, at least in its publication — to glance over its pages TESTIMONY OF THE ROCKS. 83 unmoved ; while for any person who has become conversant with the mental productions of its late lamented author, and acquainted with his autobiog- raphy, to peruse the volume without the deepest emotion is impossible. Hugh Miller was not only one of whom his country and his class were justly proud, but a man whose wondrous natural endowments, as well as dazzling scientific acquirements made under such peculiar difficulty, all the educated and thinking portion of civilized mankind, his contemporaries, regarded with well-merited admiration. Under the influence of such feelings, deepened and heightened by a recollection of the awful circum- stances under which the grave has so recently and so prematurely closed over what was mortal of this extraordinary man, we address ourselves to the task of reviewing this his last contribution to the science and literature of his country. We may, at the outset of our remarks, state, that although " The Testimony of the Rocks" might well demand a lengthened notice in our pages, the space already assigned to other matter necessarily enjoins brevity — a restriction in which we can acquiesce the more readily from the conviction that not a few of our readers will, even before this review meets their eye, have made themselves acquainted with the book itself ; and that the great majority of those who have not already done so will ere long follow their example. The largeness of demand for the volume at its first appearance, and the rapid multiplication of its impressions already, fully justify this anticipation. The design of this remarkable treatise is stated by its author briefly in the opening sentence of its graceful dedication to one of his justly valued friends, wherein he writes that the " volume is chiefly taken up in answering, to the best of its author's knowledge and ability, the various questions which the old theology of Scotland has been asking for the last few years of the newest of the sciences ;" or more definitely, as follows, in the opening lecture of the series : — " In an age in which a class of writers not without their influence in the world of letters, would fain repudiate every argument derived from design, and denounce all who hold with Paley and Chalmers as anthropomorphists. that labour to create for themselves a god of their own type and form, it may he not altogether unprofitable to contemplate the wonderful parallelism which exists between the Divine and human systems of classification ; and remembering that the geologists who have discovered the one had no hand in assisting the naturalists and phy to- logists who framed the other, soberly to inquire whether we have not a new argument in the fact for an identity in constitution and quality of the Divine and human minds, not a mere fanciful identity, the result of a disposition on the part of man to imagine to himself a God bearing his own likeness, but an identity real and actual, and the result of that creative act by which God formed man in his own image." From the above extract it will at once be perceived that the treatise was 84 REVIEWS. designed to be partly scientific and partly theological, and so it is. As such it presents a just reflection of its author's gifted mind, viewing, as was his wont, all subjects in the light of that revealed truth which he was taught in childhood, and the reverence for which he carried to his myste- riously premature grave. In making this statement we entertain no scruples, nor yet any fear of raising an imputation on the Christian religion, which the late Hugh Miller, in common with ourselves, professed. The deep-toned manly piety which runs through this remarkable volume from its commencement to its close, were there no other proof forthcoming, would in itself be sufficient evidence that the sad act which terminated at once life and his brilliant literary career, was not chargeable on his religious opinions, but the result of an over- wrought brain, ending in bona fide phy- sical derangement, and, therefore, the act of one who was at the time morally not accountable. While this characteristic of the volume, as we have said before, so greatly adds, in one point of view, to its interest, we are free to confess that we should have greatly preferred to see its elements separately handled by its late gifted author. The circumstances under which it was composed and given to the public may have rendered its present form necessary ; yet, we cannot but regret that its distinctly scientific portions have not been treated rather more apart from its theological views. And this leads us to observe, on the character of the volume, generally, that it would, in our judgment, have been much more effective, as regards its avowred objects, had it been thrown into one condensed and continuous essay, instead of being allowed to retain the form of so many distinct lectures. These lectures are twelve, and the preface informs us that they were nearly all composed and delivered during a period of about five years, and before very different auditories. Four were read before " the Edinburgh Philoso- phical Institution," one "at Exeter Hall" before "the Young Men's Chris- tian Association," and the substance of two others before " the Geological Section of the British Association" at Glasgow. Three of the remaining five were also, we are informed, addressed viva voce to popular audiences, so that but two appear in print, for the first time, in the volume before us. Now, without saying a word to disparage the admirable tendency of the whole, or to depreciate the valuable geological facts which abound in the volume (especially in the two concluding lectures on the Fossil Flora of the author's native land), we must, in candour, say that we have laid down the work, as well on its first perusal, as after a second and more careful review, with a feeling of regret, if not of disappointment, that the author's mag- TESTIMONY OF THE ROCKS. 85 nificent design had not come before the world in a more concise and con- centrated form. Recollecting the delight with which, years ago, the stone mason of Cromarty had introduced us to the marvellously beautiful and previously all but unknown organisms of the old red sandstone formation, the power- ful intellect, under the control of deep piety, with which the same hand had " crumpled up" the audacious sciolist who anonymously ventured on the " Vestiges of Creation," and further, the racy native eloquence with which, in his beautiful autobiography, he had so modestly, yet so well schooled, not only the class from which he sprang, but his fellow-countrymen of every class, we must confess to the opinion that this great man, chiefly, perhaps, owing to the form which his last work has been permitted to wear, has done full justice to neither his subject nor himself. As already remarked, the last two lectures are more strictly scientific^ and herein the student of Fossil Botany will find a rich treat. It is highly interesting to observe how, in the lapse of comparatively few years, and amidst the engrossing occupations, mercantile and literary, wherein their lamented author was, of necessity, engaged, the few sparse and spare veget- able organisms which he had noted, or figured, in his work on the Red Sandstone had grown into the rich and beautiful Fossil Flora which is here revealed. We cannot but again remark, that were the substance of these last lectures embodied with, or supplemented to, that on " the Palseontolo- gical History of Plants" in the first, and these followed in succession by the sketch of Animal Palaeontology in the second, the lucidus ordo, so necessary to the subject whose development is aimed at in the whole,, would have been much better attained. As regards the professed design of the entire volume, or of the greater portion of it, namely, the harmonizing of the two records, Mosaic and Geological, we thankfully acknowledge the obligation under which both true science and genuine religion are laid by the writer. Hugh Miller meets most of the objections raised by half-informed scepticism to the Divine revelation in the true and only way in which such ever ought to be met. He here assumes what he has elsewhere so abundantly evidenced, that both volumes, nature and revelation, are from the same Author ; but, as any really deep and clear thinker perceives and admits, on entirely dif- ferent subjects. Armed with these undeniable first principles, he meets and successfully foils his opponents. A specimen of the manner in which some of the questions thus introduced are handled will not be unprofitable K 86 REVIEWS. to our readers. Thus, for example, he writes on the hitherto much debated question of death in the inferior animals before the fall of man : — 11 It has been weakly and impiously urged — as if it were merely with the geologist that men had to settle this matter — that such an economy of warfare and suffering — of warring and of being warred upon — would be, in the words of the infant Goethe, unworthy of an all-powerful and all-benevolent Providence, and in effect a libel on his government and character. But that grave charge we leave the objectors to settle with the great Creator himself. Be it theirs, not ours, according to the poet, to ' Snatch from his hand the balance and the rod, Kejudge his justice, be the god of God.' Be it enough for the geologist rightly to interpret the record of creation — to declare the truth as he finds it — to demonstrate, from evidence no clear intellect ever yet resisted, that He, the Creator, from whom even the young lions seek their food, and who giveth to all the beasts, great and small, their meat in due season, ever wrought as He now works in his animal kingdom — that He gave to the primaeval fishes their spines and their stings, to the primaeval reptiles their trenchant teeth and their strong armour of bone, to the primaeval mammals their great tusks and their sharp claws — that He of old divided all his creatures, as now, into animals of prey and the animals preyed upon — that from the beginning of things He inseparably established among his non -responsible existences the twin laws of generation and of death ; nay, further, passing from the established truths of Geologic to one of the best established truths of Theologic science — God's eternal justice and truth — let us assert, that in the Divine government the matter of fact always determines the question of right, and that whatever has been done by Him who rendereth no account to man of his matters, He had in all ages, and in all places, an unchallengeable right to do." And this, after all, is the only way to meet such a question. To doubt the prevalence of death, among the lower creatures, in the pre-Adamitic world, with the stereotyped records of geologic investigation laid before us, would be, in our judgment, the act of perverse blindness. To assert that such discovered facts are counter to the revealed history of our race is most false and fatuitous theology. When, in the sacred volume, the introduction of death is predicated of sin, as its consequence, it is sufficiently plain, to any reasoning mind, un warped by prejudice, that both this event and its results are limited to the human race. The pre-existent state of consumption and death among the multitudinous occupants of sea and land and air, so far from exhibiting to the imagination a reign of terror, presents, when fairly viewed, merely a balanced state of momentary extinction to the inferior creature, and of enjoyment to the higher and more powerful. If left, then, to settle such a question, as Hugh Miller leaves us, by reason, we feel that such a task may be performed without any strife between the revealed and the discovered truths of Genesis and geology. The distinct paths of these two great sources of our knowledge are very beautifully marked out, in the Lecture on " The Discoverable and the Revealed," and the conclusion arrived at is thus truly and tersely TESTIMONY OF THE ROCKS. 87 stated (p. 376) : — " Scripture draws practically a broad line between the two modes ; and while it tells man all that is necessary to his wants and welfare as a religious creature, it does not communicate to him a single scientific fact which he is competent to find out for himself." Owing to the disjointed nature of the contents of this volume, already indicated, we feel it impossible to give an accurately analytical survey of the subjects handled. Among these, however, two stand out most prominently, both on account of their inherent interest and the manner in which we find them here dealt with. These are, "the Noachian Deluge ," treated of in two Lectures, the 7th and 8th, and the much debated question of our planet's antiquity. As introductory to our author's discussion of the theories held respecting both these questions, a highly interesting Lecture, the fourth, is taken up with an investigation of the modus in which the inspired historian of creation received his impressions and knowledge of the facts recorded by him. This the author, following in the wake of some continental writers, especially Dr. J. H. Kurtz, Pro- fessor of Theology at Dorpat, as well as of some of his countrymen, believes to have been by a vision, actually presented to Moses, in which the scenes of creation, progressively, from its chaotic to its perfect con- dition, passed before him, in a species of dramatic form. If such a question be ranked by some among the curious, we see nothing in Mr. Miller's determination of it to which, on the score of theological sound- ness, objection can reasonably be made. At page 258, and the following ones, the reader will find a singularly striking exemplification of the versatility of talent which existed in the mental constitution of the departed writer. He sketches out, with great vigour and boldness of conception, what he terms " a possible poem" on creation, wherein all the phases of that glorious work, as he supposes them to have appeared to the inspired vision of Moses, are made to pass before the reader's imagination. This sketch, in some of its details, recalls to mind the lovely poem, on a kindred subject, of James Montgomery, " The Pelican Island ;" but as beyond our province, we merely note this very splendid and sparkling interlude, in a volume more strictly designed to illustrate a scientific subject, as worthy of a passing comment. As regards the extent of the Noachian Deluge, Mr. Miller takes the view previously adopted and maintained by the able and pious American writer, Hitchcock, namely, that its range was limited to the then humanly peopled portion of the earth. His reasoning is grounded on the admitted facts of physical geography and geology, as well as the still existing 88 REVIEWS. conditions of animal life, while a scrupulous regard is paid, throughout, to the statements of the Inspired Record, as well as the character and acts of its Divine author. We confess that our author's reasoning on this point appears to us un- exceptionable ; as a specimen we present our readers with the following summary : — "The deluge was an event of the existing creation. Had it been universal, it would either have broken up all the diverse centres, and substituted one great general centre instead — that in which the ark rested ; or else, at an enormous ex- pense of miracle, all the animals preserved by natural means by Noah would have had to be returned by supernatural means to the regions whence by means equally supernatural they had been brought. The sloths and armadilloes — little fitted bv nature for long journeys — would have required to be ferried across the Atlantic to the regions in which the remains of the megatherium and glyptodon lie entombed ; the kangaroo and wombat, to the insulated continent that con- tains the bones of the extinct macropus and phascolomys ; and the New Zealand birds, including its heavy flying quails and its wingless wood-hen, to those remote islands of the Pacific in which the skeletons of Palapteryx ingens and Dinornus giganteus lie entombed. Nor will it avail aught to urge, with certain assertors of an universal deluge, that during the cataclysm, sea and land changed their places, and that what is now land had formed the bottom of the antedi- luvian ocean, and vice versa, what is now sea had been the land on which the first human inhabitants of the earth increased and multiplied. No geologist who knows how very various the ages of the several table-lands and mountain- chains in reality are could acquiesce in such an hypothesis ; our own Scottish shores — if to the term of the existing we add that of the ancient coast -line — must have formed the limits of the land from a time vastly more remote than the age of the Deluge. But even supposing, for the argument's sake, the hypo- thesis recognised as admissible, what, in the circumstances of the case, would be gained by the admission ? A continuous tract of land would have stretched — when all the oceans were continents aud all the continents oceans — between the South American and the Asiatic coasts. And it is just possible that, during the hundred and twenty years in which the ark was in building, a pair of sloths might have crept by inches across this continuous tract, from where the skele- tons of the great megatheria are buried, to where the great vessel stood. But after the flood had subsided, and the change in sea and land had taken place, there would remain for them no longer a roadway ; and so, though their journey outwards might, in all save the impulse which led to it, have been altogether a natural one, their voyage homewards could not be other than miraculous. Nor would the exertion of miracle have had to be restricted to the transport of the remoter travellers. How, we may well ask, had the Flood been universal, could even such islands as Great Britain and Ireland have ever been replenished with many of their original inhabitants ? Even supposing it possible that animals such as the red deer and the native ox might have swam across the Straits of Dover or the Irish Channel, to graze anew over deposits in which the bones and horns of their remote ancestors had been entombed long ages before, the feat would have been surely far beyond the power of such feeble natives of the soil as the mole, the hedge-hog, the shrew, the dormouse, and the field vole. Taking this ground, and successfully maintaining it, in such companion- ship as the eminent American writer already mentioned, and the late learned and devout Dr. J. Pye Smith, and others like them, Mr. Miller's views will» we feel, commend themselves to most, if not all, who give them a fair consideration. TESTIMONY OF THE ROCKS. 89 As regards the other theologico-geological question, as it may be termed, the age of our planet, Mr. Miller takes up, very decidedly, and expands the theory suggested first by Chalmers, and adopted by Buckland, Cony- beare, Sedgwick, and others, contending that the days of the Mosaic Record are to be interpreted not of literal periods of time, of twenty-four hours length, but of vastly prolonged measures of duration, extending, it may be, to many millenaries each. In advocating this view our author, as already intimated, goes farther than the illustrious Chalmers, in his scheme for bringing into harmony the Mosaic narrative and the geologic record. That scheme taught, as, possibly, most of our readers are aware, that " between the first act of creation, which evoked out of the previous nothing the matter of the heavens and earth, and the first act of the first day's work recorded in Genesis, periods of vast duration may have inter- vened ; but further, it insists that the days themselves were but natural days of twenty-four hours each j and that ere they began, the earth, though mayhap in the previous period a fair residence of life, had become void and formless, and the sun, moon, and stars, though mayhap they had before given light, had been, at least in relation to our planet, temporarily ex- tinguished"— p. 117. This view, though he himself once also held it, our author gives up, as but partially true, and he endeavours to show that each of the Mosaic days was of the nature and length already described. Most gladly would we enrich our pages with the reasons adduced in sup- port of this view, but we must content ourselves with commending their perusal, throughout, to our readers. We shall merely add, that, for our- selves, we are strongly disposed to accept Hugh Miller's demonstration of the harmony between Revelation and Fact on this point. These can never disagree, and, in this case, instead of disparity he points at marvellous and beautiful coincidence. Page after page in the past volume of geological research is turned over, and imbedded in its rocks are seen the traces of the great Creator's hand, to the same effect, and in precisely the same order, as the Mosaic record indicates. We take leave of this remarkable volume, if not with all the anticipa- tions realized which the well earned reputation of its author had inspired, yet with deepened admiration for his wonderful ability and laborious re- search, and still deeper regret at the awfully mysterious event, in God's permissive providence, which has bereft the sister country of one of its most justly loved and admired sons, and modern science of one oflts brightest ornaments. 90 REVIEWS.

All by Philip Henry Gosse, F.R.S., &c, &c. The first volume in the above list contains a detailed record of a summer holiday spent in the lovely watering-place of Tenby, situated at the entrance of Carmarthen Bay, South Wales. The information given is necessarily of a varied character, and we find ourselves at one moment invading Penally Bog in company with the fair botanists of Gumfreston, picking our steps between masses of the panicled sedge and beside tufts of the Osmund Royal. Next we enter upon a chapter that discusses a subject not more interesting, perhaps, than a botanical excursion with ladies, but still deeply fascinating as being one of those realms of cloud land that stud the horizon of the Naturalist — we refer to the chapter on the Pedicellariae. Here, amid the opinions of Sharpey, of Forbes, Agassiz, Valentin, Sars, and many others, we fairly fear to form an opinion of our own ; or if we do, we but throw a little more mist around the subject. Such, too, is the chapter that treats about Sagitta bipunctata. Will a master-mind ever arise that can grapple with all the difficulties of natural science ? or must these gordian knots be untied by the slow, persevering work of ages. A striking feature in "Tenby" is the account of various microscopic objects. We have a whole chapter on the Rotifera, another on dipping for animalcules in Knightson Pond, and several devoted to the examination of the various animals whose united brilliancies anon cause the very sea to flash and sparkle like a lightning-lit sky. While there is abundance of information in this volume to make it a most desirable acquisition to the library of every lover of nature — some of the chapters bearing evidence of the most painstaking research, others adding a great deal to our knowledge of the metamorphosis of marine animals — yet to the visitor to Tenby, or a naturalist living within or near this wall-girt town, it must present most peculiar charms. Hardly a cave or a fountain, not a pleasant walk or delightful old ruin, but is photo- graphed in this volume ; pleasant memories revived within as we read the pages ; there, as we looked towards the Bristol Channel, lay the mighty TENBY. 91 sea, tranquil and quiet, sparkling amid the intense glare of a July sun ; for a little while we see nothing but the glittering waters, — then the pleased eye rests on the large safety buoy out on the very horizon — the rescuer from a watery, wintry grave of many a poor fellow — then Caldy Isle grows upon the view, and then the whole deep is alive with the snowy plumaged gannets ; too far off, we hear not their discordant cry, but as they quickly sweep along — now seen, now lost — they rather add to than take from the impressive quietness of the scene. St. Catherine's Rock, too, crowned with the ruins of an old chapel, now grown hoary with the gray lichen that mantles its broken-down walls and makes them look so venerable ; it was a pleasant place to resort to. A winding stairs brings you to its summit, where you could lie down and study man as many a variety of this one great species walked along the yellow sands beneath you ; there were happy children digging with their little spades moats and pits in the soft sand, as thoughtless of the next tide which will sweep all their work away as their elders are of the scythe of time. Or let the naturalist go beneath this rocky islet and he will find it full of caves, and in them he will find — but we won't tell him, for the volume before us does, and that in a manner beyond our pretensions. The appendix is a great addition to this volume, especially the part that treats of the sub-division of the Actinias, and there is a valuable systematic index of the Invertebrata mentioned in the volume. We must now pass on to notice the second part of the British Marine Zoology. It contains the Sub-kingdoms, Mollusca (which takes up the greater portion of the volume) and Vertebrata. We think there cannot be a doubt but that Mr. Gosse's Manual, which this part completes, is the most useful work that has been for a long time, if ever, published. To think of bringing Mr. Van Voorst's series of works on British Natural History to the sea -side with one was really quite enough to keep one from the sea-side for ever. Why they would take up the room of an adult passenger, or of a couple of children ; and then, supposing them once there, who could carry " Forbes and Hanly" in their waistcoat or any other pocket ? The thing was almost impossible ; but now, thanks to our author, we have, by binding the two parts in one, a nice little volume quite easily carried, quite easily referred to, and one that in future it will be quite impossible to do without. Mr. Gosse says that, by a most singular coincidence, the number of genera in both parts — the first containing the Radiate and Annulose forms — are both alike, namely 339. Now, we really think all this allusion about 92 REVIEWS. " singular coincidences" might have been omitted. Nature is not ruled by numbers ; and in the very next paragraph he tells us of a supplement in which we find some nineteen or twenty genera added to the Annulose forms. We have a very high opinion of Mr. Gosse's powers as a draughtsman, and the figures in the first part are indeed excellent ; but we regret that we cannot speak as favourably for many of the sketches in the second part. We know it is not so easy to give a characteristic sketch of a Mollusc as it is of a sea anemone ; but we think a little more trouble might have been profitably spent in delineating the first sub-kingdom in the part now under notice. Some of them would better stand for Egyptian hieroglyphics than for British shells — as, for instance, figures 71, 74, 99, 100, and 103. Others again, while we might be able to identify them, give very erroneous ideas of the shells, the outline being so imperfect — as 64, 73, 82, 90, 97, 104, 107, and others. We could give many more instances under both lists, but forbear. One of the generic distinctions among the Cephalopoda is one that admits of being given in a hasty sketch — viz., the arrangement of the suckers — and we would have been glad to have seen the figures of them given more in detail. The figures of the vertebrate animals are better, some of them being excellent. Figure 240, a copy after Yarrell, faithfully follows Yarrell's mistake about the caudal fin, which should have the first and last rays nearly one-fourth as long as the centre ones. We were sorry to see that the Sea Birds were not given among the Vertebrates, as they form, in our opinion, a very essential portion of Marine Zoology ; but Mr. Gosse seems to have forgotten the birds since his sojourn in Jamaica. We seldom see even a reference to them in his lately published works. Our Roseate Terns may not vie with the lovely Hum- ming Birds of " Bluefields ;" still they and their brotherhood ought not to be slighted. Many additions have been made to our British Fauna, even since the publication of this last part ; and we would suggest to Mr. Gosse that it would be advisable to publish every two or three years a supplement to these volumes, thus bringing them up to the standard of the day, and that he should give us figures of all the new genera. The last work on our list deserves a passing notice. It gives us a very pleasing sketch of animal life from its lowest to its highest form. It is very neatly printed, and nicely illustrated ; and we do not know of a better volume on the subject. The language is simple, and yet the dignity of the science is not lowered, and a pleasant, healthy tone pervades every page.

Those who have had any experience in imparting to the young a know- ledge of the various organised beings which inhabit our globe must have long felt the need of a series of accurate representations illustrative of the leading types of animal life. To supply this want, the above diagrams have been prepared under the superintendence of Mr. Robert Patterson, the well-known author of" Zoology for Schools," and the little tract, the name of which we have also mentioned, has just been published, " as a key to the classification" adopted in the diagrams, "in deference to a demand made for such an explanation by many purchasers of the latter." It is true that most professors of zoology are provided with diagrams of their own, which are, and always will be, necessary to exhibit to the stu- dent the many details of structure with which it is desirable that he should be made acquainted. But such diagrams, from their very completeness, fail in one important particular, which ought not to be overlooked — namely, of exhibiting at a single view the relations which the several forms repre- sented bear to one another. The object, therefore, which the present series is intended to fulfil is two-fold — 1st, To give accurate figures of the individual animals selected for illustration ; and 2nd, To convey correct ideas of the general principles of zoological classification. It gives us much pleasure to state that in the first of these objects Mr. Patterson has been signally successful. It matters not which of the sheets we take up, we are sure to find in all faithful representations of the origi- nal forms. One exception must be made. No mollusca ever had the bad luck of being perpetuated in so many vile figures as that of Argonauta argo, and we are sorry to see one more added to the list in Sheet F, and not one word of correction, too, in the accompanying " Explanation." The ar- gonaut sits in its boat, with its siphon turned towards the keel (so far Mr. Pat- terson's figure is right), and its sail-shaped (dorsal) arms closely applied to the sides of the shell (here the diagram is quite wrong, as they are quite withdrawn) : this might have been to show the margin of the aperture ; if so, why does not the explanation say so, as it is likely to confirm most L 94 REVIEWS. erroneous impressions ? In the grouping of the animals considerable taste has been displayed. In general, the selection of the species which are to serve as types of the group or order to which they belong is judiciously performed. This, however, is not always the case. Thus, of the numerous division of Edriophthalmatous Crustacea no species is shown, while four figures of Entomostraca are given. But how has Mr. Patterson succeeded with regard to the second object which he proposes to accomplish ? Has he been able to present the student with a correct and characteristic outline of the animal kingdom, ac- cording to the views of modern zoologists ? To perform this satisfactorily is no easy task. Zoology is from its nature a progressive science, and whatever arrangement may be determined on is liable to receive more or less alteration from the new relations which some fresh discovery may suggest to the philosophic naturalist. But let us inquire what are the ob- jects which a well-devised system of zoological classification proposes to effect. " The natural history of an animal (says Cuvier) is the knowledge of the whole animal/' But such a knowledge, though most essential, is still insufficient. It has been well said, that " in the several tribes of organised beings we have not a mere aggregation of individuals, each formed upon an independent model, and presenting a type of structure peculiar to itself; but that we may trace through each assemblage a conformity to a general plan, which may be expressed in an 'archetype' or ideal model, and of which every modification has reference either to the peculiar conditions under which the race is destined to exist, or to its relations to other beings. Of these special modifications, again, the most important themselves present a conformity to a plan of less generality ; those next in order to a plan of still more limited extent, and so on, until we reach those which are pecu- liar to the individual itself. This is, in fact, the philosophical expression of the whole science of classification."* The systems adopted in the present day are, more or less, modifications of that of Cuvier. Since the time when that system was promulgated very many discoveries have, however, been made, which must considerably alter our views of the Cuvierian arrangement. Too^hastily to adopt all the innovations which have been suggested would, indeed, be injudicious ; but, still, we may regard one great fact as having been clearly established — namely, that there exist five very distinct plans of structure, or " types," to some one of which any animal form (taking into account, likewise, its * Carpenter's Comparative Physiology, p. 10. ZOOLOGICAL DIAGRAMS. 95 grade of development) may be referred. The names of these types are as follow : — 1st. Vertebrata — which may be divided into two sections, the first, M Abranchiata," including mammals, birds, and reptiles ; the second, " Branchiata" — amphibians and fishes. 2nd. Mollusca, divided into two groups — 1st, true mollusca, and 2nd, molluscoida. The last division includes the brachiopods (?), tuni- cates, and polyzoa. 3rd. Annulosa, which also is separable into two groups — 1st, true annulosa, which includes insects, myriapods, spiders, and crustaceans ; 2nd, annuloida, comprising echinoderms, annelids, rotifers, and the flat- bodied and nematoid worms. 4th. Ccelenterata, including zoophitic and acalephoid forms. 5th. Protozoa. — In this division are placed the sponges, rhizopods, and true infusoria. In certain matters of detail this classification is, no doubt, imperfect. Thus, the true position of the echinodermata is still a matter of uncertainty. But, on the whole, it gives us the best general expression of the views of modern zoologists which the present state of science is capable of afford- ing. We are now in a position to estimate the merits of the arrangement which Mr. Patterson has adopted in his diagrams. The first great error that we meet with is that Mr. Patterson completely ignores one of the most important conclusions which the united labours of many recent researches have established, namely, that two types of organization are included under the radiata of Cuvier (i.e., the last two types in the classi- fication above given). At page 45 of the " Explanation" we are informed that the radiata are arranged in six classes : Echinodermata, Acalepha, Zoophyta, Entozoa, In- fusoria, Foraminifera, and Amorphozoa, are the names of the classes given. Any child would say that seven classes are here mentioned ; but on turn- ing to the diagrams themselves we find an explanation of this apparent anomaly ; for the Echinoderms and Acalephs are included together under one class, termed " Radiaria," a name which is employed with the same signification in the " Zoology." We cannot congratulate Mr. Patterson on this original arrangement. The slight external resemblance between some of the medusa and star fishes is surely insufficient to justify any such near association of these animals, as Mr. Patterson proposes. The only allusion to the affinity of the zoophytes with the acalepha is a 96 REVIEWS. scanty extract from Professor E. Forbes' monograph on the British naked- eyed medusae, given at page 56 of the " Zoology." But the time relation of these remarkable organisms to one another seems altogether to have escaped the notice of Mr. Patterson. The connection between the polyzoa and tunicata is regarded by Mr. Patterson merely in the light of a close affinity, but he still thinks it pro- per to rank the former as one of the orders of the zoophyta. The incor- rectness of this has long since been shown by the researches of J. V. Thompson, Milne Edwards, Professor Allman, and others. The entozoa are classed among the radiata instead of among the annu- loida. The correctness of this is, however, questioned at page 56 of the "Zoology." It would be doing injustice to the author were we to have it understood that his classification is a mere copy of that of Cuvier. In more than one instance the improvements of modern naturalists are adopted. Thus, the arrangement of the mammalia is good, though the monotremes are not regarded as a distinct order. Again, the cirripeda are removed from the mollusca and placed among the articulata, next to the Crustacea. It would, perhaps, have been better to have ranked them as a subdivision of the latter. The myriapoda are not made into a separate class. The importance of the study of development does not seem to be duly recognised by Mr. Patterson. Our most eminent zoologists have long since shown that the amphibia are distinguished by sufficient peculiarities to jus- tify their separation from the reptilia (vide Bell's Reptiles, page 73). Mr. Patterson still, however, regards them as constituting one of the orders of the reptilia. In his arrangement of the birds, Mr. Patterson reduces all known species to five orders. The Scansores are by him included among the perching birds. The Columbse are not distinguished from the Rasores ; and the Cursores, which surely form a separate order, are by him placed among the Grallatores. Our knowledge of the present group is, perhaps, still encum- bered with too many difficulties to enable Mr. Patterson to have arrived at a much more satisfactory arrangement. The same excuse will, however, not serve with relation to Sheet H, in which the order Aptera most unwelcomely makes its appearance. Who does not know that the flea should be located among the Diptera, and the spring-tail among the Neuroptera, and so on with the other genera (?) of this order. On the whole, it must be admitted that Mr. Patterson's classification ZOOLOGICAL DIAGRAMS. 97 falls far short of that adopted by the majority of modern scientific natural- ists. It is much to be regretted that in so excellent a series of diagrams as the present, in which the figures of many of the animals are executed with almost faultless accuracy, scarcely any use seems to have been made of the advanced views propounded by our most distinguished zoologists. One purpose of the diagrams as a most important educational instrument is thu*s defeated. A high responsibility attaches itself to all who are in any way concerned with the education of their younger or less enlightened brethren ; much more to those who take a lead in devising those schemes of education which are entrusted to others to be carried into execution. Their very eminence causes their instructions to be listened to, when those of others would be unheeded ; and if they convey false views of knowledge, or partial notions of important truths, great, indeed, will be the injury thus inflicted upon a large class of the community. With what difficulty are errors easily implanted eradicated from the youthful mind ! How many have had to de- vote a large portion of time and thought to unlearn what careless and in- " competent teachers have but too successfully instilled. We have been thus critical in noticing these diagrams, not because we think that their defects wholly counterbalance their merits, or that the author has not rendered real service to the cause of natural history. The well-known and deserved success of Mr. Patterson's " Zoology for Schools" is a sufficient reply to such an insinuation. Nor would we be willing to sur- render this much-cherished little volume for other works of far less utility, but of more pretence. But we trust that in a new edition the errors which we have referred to, both in the " Zoology" and " Diagrams," will be amended. A trifling expenditure of time and trouble will be able to effect this desirable alteration. To use the words of a former reviewer — " State- ments now known to be erroneous continue to be given, without even (in many cases) a foot-note to warn the reader of the changes of opinion which are consequent upon the advance of zoological knowledge." We wait, then, in hope for a speedy correction of all these objectionable passages. We feel assured that an author who has already accomplished so much for zoology will not be tardy to avail himself of these friendly suggestions. And among the honourable names of those naturalists who have generously laboured widely to diffuse the truths of the great science which they have so successfully cultivated, few will be entitled to more lasting praise than that of Robert Patterson. 98 REVIEWS. Atlas of British Sea Weeds. Drawn from Professor Harvey's Phycologia Britannica. 4to, in numbers, 6s. each. Nos. I. II. Synopsis of British Seaweeds. Compiled from Professor Harvey's Phycologia Britannica. 8vo> Price 5 s. Lovell Reeve. Seven years have now elapsed since the publication of Professor Harvey's " Phycologia Britannica," a work which has long been considered indis- pensable to all who desire information concerning the interesting groap of plants which it professes to describe. But, owing to the care which has been bestowed upon its numerous and beautiful coloured illustrations, its price has necessarily been fixed at a rate which must have precluded many from becoming its purchasers. Desirous of obviating this, and thereby introducing Dr. Harvey's work to a more numerous class of subscribers, Mr. Lovell Reeve has commenced the publication of " The Atlas of British Seaweeds," which is simply a reproduction of the plates of the Phycologia on a smaller scale. The work of reduction has been, on the whole, well performed, although some of the figures, as that of Cystoseira fceniculacea, show the charac- teristics of the species represented less distinctly than they might have been. To accompany the Atlas, an abstract of the text of the Phycologia has been published in a separate volume, under the title of the " Synopsis of British Seaweeds." To purchasers of the Atlas, this Synopsis will, of course, be indispensable, but we would also recommend it even to those who possess the " Phycologia." Its small size renders it a convenient pocket volume, and Dr. Harvey has given in the Appendix a new arrange- ment of the British Rhodospermiae in accordance with the views of Pro- fessor Agardh, together with the titles of those Rhodosperms whose names have been altered. Since the Phycologia was completed new species of British Algae have been discovered, and an inventory of the latter is given at page 206 of the Synopsis. Descriptions and figures of most of these (by Professor Harvey) will be found in the present number of the Natural History Review.* To the same paper we would also refer the reader for a descrip- tion of Elachista Grevilli, a new species not mentioned in the Synopsis. The Atlas is being published in ten monthly parts, two of which have already appeared. When completed, its price (including the Synopsis) will be less than half that of the original work. J. R.

Royal 16mo. Twenty Coloured Plates. By G. B. Sowerby. 358 pages. 10s. 6d. London. L. Reeve. One of the most comprehensive of the many useful hand-books published in this series ; short descriptions of four hundred species of Crustacea being given, and figures, more or less characteristic, of ninety-six, some of them now figured for the first time. No pains have been spared to render this work as complete a manual as possible, and the author has, we must say, succeeded in laying before the student an almost complete picture of the Crustacea of the seas around Britain and the Channel Islands. When we recollect that to this end he was compelled to wade through the natural history magazines and transactions for the past fifteen or twenty years, we can form some idea of the difficulties to be surmounted, and of the valuable time which such a book as this will save to the enquirer. The characters of the species are for the most part brief, but generally sufficiently diagnostic to enable us to identify any species. In one or two instances pleasant details of habits have been judiciously introduced. The number of new species here incorporated in the British lists are many, but time and want of means of comparison with published lists preclude our notic- ing more than a few. In the decapods we have, Scyllarius arctus, Alpheus affinis, Autonomea Olivii, Hippolyte fascigera, Grayana, Mitchelli, Whitei^ Yarrellii, Barleei, and pusiola (as H. Andre wsii), Crangon Allmanni, Mysis Lamorna, productus, Oberon, and a new but unnamed species. Seven species of Diastylidae are noticed, nearly all additional to the species in " Bell's British Crustacea." Among the Amphipods we find the following, which had escaped the notice of Spence Bate : — Opis typica, Anonyx elegans, Unciola irrorata, Amphithoe obtusata. Among the Entomostraca many additions will be found, but space forbids our noticing them. The only fault we have to find consists in what we must (in the majority of cases) look on as a needless change in the nomenclature generally adopted in this country, and although this has arisen from a rigorous adherence to the laws of priority, yet we cannot help thinking that such changes as Arc- topsis for Pisa, Potamobius for Astacus, and, worse still, Astacus for Ho- rn arus, are extremely injudicious. Very few would recognise under the names of Astacus Gammarus and Potamobius fluviatilis the Homaris vulgaris and Astacus fluviatilis of most modem authors ; and surely the crayfish has as good a right to the name Astacus as the lobster. There are, in our mind, just as many inju- dicious changes among the specific names, but these we pass over. It is 100 REVIEWS. more pleasant, however, to dwell on another, and as far as a British book is concerned, a somewhat novel character — viz., the frequent mention of, and reference to, Irish authorities and localities, this is as it ought to be, although in one or two cases there are inaccuracies on this head — for instance, M'Calla's discovery of Thia polita is here given to Dr. Scouler, and, under Munida bamfica, we are incorrectly informed — " It is common on the Irish coast." Yet, still, we must hail this as a step in the right direc- tion. The usual inconvenient arrangement of the plates, which marks all this series, prevails here, but for this the author is not responsible. We think we cannot conclude better than by recommending this little book to any one studying the subject, its size and conciseness suiting it alike for the pocket and the sea-shore study, and though many additions will, doubt- less, be annually made to our list, yet, for ordinary purposes, this book will be found a sufficient guide to the student for many a long day.

To both Mr. Warrington and Mr. Gosse the credit of having discovered the Aquarium may fairly be given, and to the works of the last mentioned naturalist may be attributed the rapid spread of knowledge in connection with its improvement and more universal application, which has recently taken place. The charming volumes of this popular writer, together with Dr. Harvey's Sea Side book, and Mr. Kingsley's Glaucus, contain all necessary information concerning the history of marine animals which the student requires, save in the more recondite matters of detail, for which the various monographs and scientific journals must be consulted. But certain obscure and ill informed persons, observing the popularity which the above works had so deservedly obtained, and taking advantage of the ignorance of the public, on a subject almost entirely new, have lately taken THE AQUARIUM. 101 to publish books of their own, treating of the Aquarium ; a list of the more recent of which productions we have placed at the head of the present article. To Mr. Sowerby's volume we will first call the attention of our readers. The book is for the most part made up of quotations selected from the works of Bell, Baird, Forbes, Gosse, Harvey, Hugh Miller, Owen, and others whose names have appeared to the author sufficiently eminent to be deemed worthy of his patronage. At page 199 he tells us, when speak- ing of the Entomostracea, " that, having had but little Opportunity of in- vestigating these little creatures myself, this part of our book must take the character of a compilation, more completely than some of the others ;" and, accordingly, he proceeds to avail himself of Dr. Baird 's work on these crustaceans. His opportunities of investigating in their native haunts the animals which he professes to describe would not appear to have been numerous. Frequent allusion is made to the marine animals at Mr. Lloyd's establishment, and, at page 209, Mr. Sowerby confesses that "the only opportunity I have had of observing a living specimen of the Entomos- traceous division of crustaceans was that afforded me by the attendant at the Zoological Society's Fish- house." But though our author's journeys to the sea side are not very often performed, yet, when he does go there, it falls to his lot to observe phenomena very different from those which are com- monly noticed. Acute and original powers of observation are, to a naturalist, desirable qualities, and these Mr. Sowerby possesses in a very eminent degree. Thus, in the first paragraph of the book, he informs us that " pebbles throw out their long arms, fringed with net work, in many a case, for food." A mere observer of facts, however, Mr. Sowerby is not. On more than one occasion the philosophic bent of his mind is shown by pecu- liar and ingenious interpretations of the observations made by others. Thus, after describing the habits of the hermit crab, he adds — " Might it not be that the zoe or tadpole form of some common species, produced where empty shells of different sorts and sizes lie strewn plentifully among pebbles and sand, falling into some of the hollows and becoming confined or liking the condition, remained in it through subsequent changes, and that thus what is first an accident becomes a habit." We presume that the above are some of the " original observations and opinions, many of which will be new to the reader," which the author promises in the preface. At page 1 8 we are told that Acephala (Acalepha? ?) will not live well in confinement when full grown ; although some of them, in their early hydro id stages, are interesting. To what hydroid forms does Mr. Sowerby allude. Surely, if he has any notes of his own on those interesting " forms," he might M 102 REVIEWS. have made known some facts, which science is not yet in possession of ; or is he aware what " hydroid forms" mean, and that the term " stages," as applied to such organisms, is incorrect, since no metamorphosis, strictly speaking, can be said to occur in these animals. In his account of Laomedea geniculata, he says that " this Zoophyte has the power of throw- ing off the polypi, or, rather, the little polypi are able to detach themselves and still to dance merrily in the water." He makes some quotations from Mr. Gosse, grievously, however, misrepresenting the statements of that naturalist, and then remarks that the polypes " resemble an inverted umbrella, with a nettled disk across its diameter ; on the converse side is a central fleshy protuberance, forming the foot." We believe Mr. Sowerby when he informs us, in the preface, that his " personal observations of Hydroid Zoophytes are very limited." He here confounds the true polype heads of the Laomedea with the medusoids generated in the interior of the productive capsules. The former remain stationary at the top of the stalk on which they were placed, and are the organs by which the Zoophyte procures its nutriment ; the latter are reproductive zoids rendered locomotive, whose functions is to produce ova, which may develope into the likeness of the parent Zoophyte. What Mr. Sowerby calls the " foot" is in reality the peduncle of the medusoid. But this is not all, for " Beroe ovata" is said to have " two very long pendent tentacles, to which are attached, at regular intervals, still more slender threads, which coil like the tendrils of a vine." The truth is that Beroe ovata has no tentacles whatsoever, and that Mr. Sowerby mistakes this ciliograde for Cydippe pomiformis. The Zoophytes are described in an exceedingly confused manner, and a definition of these animals is taken from the old edition of Dr. Johnston's work, which is meant to include both Zoophytes and Polyzoa, " Eucratea chelata," Anguinaria spatulata," and " Cellularia ciliata" are placed by Mr. Sowerby among the Hydroid Zoophytes. At page 288 it is implied that Pyrosoma (one of the compound Tunicata) is a veritable fish. Many of the animals described are totally unfit for preservation in the aquarium, being either very rare (in some cases not natives of the British islands), or else unsuited to live in confinement. Who would think of keeping a snapping turtle or a crocodile in one's drawing-room, to say nothing of Euplectella Aspergillium, which we would have to send for to the Philippine islands ? or how we are to procure Pavonaria quadrangularis, Arachnactis albida, or Capnea sanguinea, one of which species has not yet been captured on our coast, perhaps, half a dozen times. Mr. Sowerby carries his zeal for rare animals so far as to describe Oculina prolifera, a COMMON OBJECTS OF THE SEA SHORE. 103 species which he himself goes on to say is rare on British coasts, and has not yet been taken in a living state. The aquarium is not, we submit, to be used as a receptacle for dead animals. Typographical (?) errors frequently occur, such as Luida for Luidia, Arachnitis for Arachnactis, Chrysoaria for Chrysaora, Acephala for Acalephas, &c, &c. In many cases the headings of the chapters and sections do not correspond with the contents of the latter. The figures, with one or two exceptions, are good, and constitute the only redeeming feature about this otherwise good-for-nothing book. It is not improbable that this work will meet with a better circulation than it deserves, owing to its introduction among the hitherto excellent series of popular Natural History works which Mr. Lovell Eeeve has published. We make this observation, lest our readers, upon discovering the faults of Mr. Sowerby's volume, might take it for granted that other works, pub- lished in the same series and wearing externally the same appearance, are intrinsically of the same inferior quality. This, we are happy to say, is not the case. "The Common Objects of the Sea Shore," by the Rev. J. G. Wood, M.A., F.L.S., is provided with engravings of Mr. Sowerby's execution. Mr. Wood had, however, sufficient good sense not * to let Mr. Sowerby meddle with the text, and we may easily suppose that the work which he has produced is, on the whole, superior to that written by his accomplished draughtsman. Indeed, he does not scruple to differ with Mr. Sowerby on certain points — thus, at page 51, he alludes to " those strange amphibious humanities who persist in declaring that the hermit crab was the young of the common edible crab, etc." This is a sad hit at Mr. Sowerby's peculiar views concerning the true nature of that crustacean. Mr. Wood proposes to describe the common objects of the sea shore only ; nevertheless, he selects, as an ex- ample of a pulmonigrade acaleph, what he calls Egeria. We take it for granted that the ^Equorea is here meant, a genus so rare on the British shores that Professor Forbes met with no species of it until after he had published his monograph on the naked eyed Medusae. The following lucid directions for the capture of the Acalephaa are given : — " If a vessel is filled with water, drawn from the surface of the sea on a calm day, there are generally a few Medusas in it ; but if there should be none, a little work with a gauze net will secure plenty," We would recommend Mr. Wood to procure Professor Forbes' monograph, from which he will derive much useful information. 104 REVIEWS. The author is a clergyman, and, of course, writes with tolerable fluency ; but he tells us nothing that is not far better told in other books. Errors, as we have seen, his work contains : but we will not stay to notice them, as we are desirous to make some observations on " Ocean Gardens," by Mr. Noel Humphreys. This book is divided into nine chapters. Chap. I. is a sort of preface, written in a grandiloquent style, in which Mr. Humphreys tells us of the sublime aspects of the ocean, the sound of its deep, ceaseless voice, the eternal oncoming of its waves (we would remind Mr. Humphreys that the tide occasionally goes out), those voices in the wind which ought to excite strange sensations of admiration and curiosity and wonder. ** But, no ; to most of the idle crowd those sights and sounds are invisible and unheard. To appreciate nature as well as art, the mind requires a special education, without which the eye and the ear perceive but little of the miracles pas- sing before them." After a few brief allusions to Socrates, Apuleus, and the Gymnosophists, Ray, Pulteney, Ellis, Linneus, Johnston, Harvey, John Edward Gray, Gosse, Forbes, and Gilbert White, Mr. Humphreys adds, '• Through the fascinating interpretation of the good Gilbert, many now understand the attraction of those branches of natural history which he so curiously investigated ; but few are willing to admit that it is as easy to make the natural features of some obscure fishing village prove equally interesting." Mr. Humphreys assures his readers that such is perfectly possible, and then proceeds, in the following chapters, to give the special education above alluded to, and to " lift the border of that dark green curtain which conceals the wonders of the ocean floor from vulgar eyes." His notion of a class is of a rather vicarious and uncertain character. The " compound" zoophytes are made into a class by Mr. Humphrejs, but the***, strange to say, include another class, the Pennatulidse. The Lucer- nariadae also constitute a class ; and, at page 63, we are told that the sponges form a curious class of zoophytes, which have, perhaps, a much closer affinity to plants than any other class. The author is in no way fettered by the ordinary views of naturalists. He tells us that " the functions of the flower-like set of organs with which the Holothuriadae are provided are probably the same as those of the Nudibranch class of Mollusks, which, though generally considered as being a breathing apparatus, are, probably, at the same time, food-collecting organs, as all the creatures thus furnished are liquid feeders." Often as Mr. Humphreys quotes the works of Gosse, he seems to have failed to notice the passages in which the voracity of the Nudibranchs in devouring OCEAN GARDENS. 105 zoophytes, etc. (which certainly cannot be regarded as liquid food), is spoken of. With a few exceptions, the names of none of the animals mentioned are properly spelt. Thus, we have Geniaster for Goniaster, Dunicata for Tuni- cata, Gastrophasna for Gastrochaena, Paguras for Pagurus, to say nothing of Sepia vulgaris for Sepiola vulgaris, Egines punctiluceus for Egirus punctilucens, with a host of others. " Stars of the class Luidia" are called brittle stars, so that the student is led to suppose that this Echinoderm belongs to the Ophiuridae. The Aplysia is described among the Nudi- branchs and the Chiton is said to be a sort of sea woodlous,e. The figures with which the work is illustrated are showy, but are executed, in general, without much regard to accuracy. The author takes a high stand upon a mound of his own erection, and frequently denounces therefrom the " superficial knowledge," " imperfect observations," which have become so injurious to science, and deplores the state of u Egyptian darkness" in which so many are involved. Shakspeare is held up as a deplorable example of an intellectual giant who could not see nature, and two mistakes in the expression, " eyeless venomed worm," are pointed out. Now, though we can show that three mistakes are here made (one of which, and that the most striking, has escaped Mr. Humphreys), yet we still think that Shakspeare could see nature a great deal better than Mr. Humphreys, and those who have read Mr. Patterson's delightful little book on the " Insects mentioned in Shakspeare's plays" will, probably, think the same. Mr. Humphreys concludes his work with a sublime apostrophe on the possibility of a gigantic aquarium — " It only remained to the ancients to have exhibited a Titanic Aquarium to render our triumph over their la- bours in the field of popular natural history impossible. Had but a Eoman Warrington or Gosse, &c, adopted the germ of such an idea, and an Osier existed to furnish the glass, the Pompey, or Caesar, or Crassus would not have been wanting to feast the eyes both of patrician and plebeian Rome, with an aquarium measuring hundreds of feet in length, in which the monsters of the deep would have been exhibited in deadly conflict, and human divers, armed with net and trident, like the retiariae of their gladia- torial combats, would have encountered beneath the waters the shark, the whale, or the torpedo, to the shouts of crowded circuses, the centre of which would have been a glass-walled aquarium. But a gigantic aquarium is, fortunately, a feat that yet remains for modern science to achieve, and 106 REVIEWS. which it will, doubtless, accomplish. The day shall arrive when we shall see the living behemoth — the Titan of the deep — rolling majestic in waves of his native element, perhaps pursued by his cruel enemy the sword-fish, or harried by a shoal of herrings, graphically exemplifying to a London crowd the origin of Yarmouth bloaters ; or we may see the dreaded shark float round and round the vast glass prison seeking his prey, and the shark hunter of the South Seas may be imported to exhibit his skill in a blood- less conflict — mocking the attempts of the sea monster to seize him, as the Spanish matador plays long with the infuriated bull, but without neces- sitating the same catastrophe to the animal, defenceless against the specially trained skill of his human antagonist. We have already had our crystal palaces, covering their acres, and filled with objects of art and wealth from every quarter of the globe ; it is not impossible, therefore, that we may have crystal-walled seas, in which aquatic menageries will form the last new object of fashion and wonder." After this display of Mr. Humphrey's powers as a writer, any lengthened notice of his other work, that on " River Gardens," must appear unneces- sary. Like its companion volume, it abounds with erroneous notions and unscientific explanations of vital phenomena. This, however, is the less to be wondered at, for no good book has yet been written on the fresh water aquarium. Thus are the beautiful lessons which the study of nature unfolds misin- terpreted by those who are incapable of understanding them, and the writ- ings of really painstaking and observing naturalists made to furnish infor- mation to greedy and ignorant compilers. But we live in expectation of better times, when such spoilers will cease to be encouraged in their evil ways, and science reap many fruits from the application of the beautiful principle on which the adjustment between animal and vegetable life is ' known to depend.
