from Jamaica, for its opening article; and in this, seventy-seven 'species are enumerated, and their habitates distinguished. This is the list-Gleichemia immersa, Aneimia adiantifolia, Polybotrya cervina, P. cylindrica, Acrostichum aureum, A. nicotianæ folium, Gymnogramma loveii, G. gracile, G. tartarea, G calomelanos, Grammitis elongata, G. angustifolia, Tænitis lanceolata, Polypodi um exiguum, P. glabellum, P. serpens, P. phyllitidis, P. crassifolium, P. pectina. um, P. incanum, P. sporadocarpum, P. loriceum, P. simile, P. reptans, P. smith anum, P. crenatum, P. lunanianum, P. miser, and P. effusum, Lomaria longifolic Antrophyum lanceolatum, Diplazium plantagineum, D. juglandifolium, and D obtusum, Pteris longifolia, P. grandifolia, P. plumerii, P. concinna, P. hetercphylla and P. caudata, Asplenium serratum, A. ambiguum, A. obtusifolium, A brasiliense, A. auritum, A. dentatum, A. rhizophorum, and A. præmorsum, Cænopteris myriophylla, Blechnum occidentale, Aspidium trifoliatum, A. macrophyllum, A. ascendens, A. exaltatum, A. hippocrepis, A. sprengelii, A. molle, A. invisum, A. venustum, A. pubescens, and A. villosum, Adiantum macrophyllum, A. serrulatum, A. radiatum, A. cristatum, A. trapeziforme, and A. tenerum, Cheilanthes microphylla, Davallia alata, Dicksonia cicutaria, Woodsia pubescens, Cyathea elegans, Trichomanes sinuosum, T. crispum, and T. scandens, Psilotum triquetrum, and Lycopodium cernuum. In certain wooded districts of the Island, the ferns are very splendid and exceedingly beautiful in their form; the segments of their multifid fronds, moving with the slightest breath of air, are constantly in motion, and give them a most elegant and graceful appearance; the newly-arrived botanist cannot but be struck with wonder at such a display of ferns, mostly unknown to him; and he is enabled to make a plentiful collection at a small expenditure of labour. Article the second is a monograph of M. Desjardins', on the genus Leptocera, with descriptions of two new species found in the Isle of Bourbon: the Leptocera mezierei and L. beaumontii are the names he has assigned to them, in honour of two distinguished entomological friends. Mr. Clarke, in an ingenious experimental essay on the organs of hearing in insects, with thirteen illustrative figures, concludes that these creatures "could hear as plainly as he could himself," that their antennæ are the organs of hearing, and that the upper part of the antennæ has the power of increasing sound. In a coinmunication on the Succinea amphibia, or amber-shell, and its varieties, Mr. Cooper points out some long-prevailing errors respecting this mollusc, and he gives six figures in explanation of his observations. Some entertaining as well as instructive remarks are contributed by Dr. Clarke, on the habits of the Coluber natrix, or common snake. Sir E. F. Bromhead proceeds with his remarks on zoological classification; and these are succeeded by Mr. M'Coy's strictures on Mr. Eyton's arrangement of the gulls; and by Dr. Hancock's notes on the Psophia crepitans, or trumpeter bird, the waracobi of the Arowahs of Guiana. Next, come Mr. Ogilby's reasons respecting the term Simia and its application; then Mr. Swainson replies shortly to some of his reviewers; and then are appended some notes by the Editor, relating to the same question.— Under the section intituled scientific intelligence, you see a letter of Lord Tankerville's on the wild cattle in Chillingham Park, and notes on the electric eel, on Artesian wells, on the electrical telegraph, and on the natural history of Nowaja Semlija and the Caucasian regions. Mr. Blyth's remarks on the doctrine of spontaneous generation; observations on the Oubudi, or great cashew-tree of Guiana; Mr. Harvey's information regarding the Tubularia indivisa; his notes on the carrion crow, the rook and the cuckoo, and on white light from burning corallines; Dr. Weissenborn's letter on the Bos urus and the instinct of animals; and Mr. Clarke's discovery of a pulmonary orifice in insects, occupy the division allotted to short communications in Mr. Charlesworth's well-conducted and truly scientific magazine. The Naturalist, illustrative of the Animal, Vegetable, and Mineral Kingdoms, with engravings; edited by Neville Wood, Esquire; royal 8vo, London, 1838. No. XXIII, August.-Mr. Lankester takes the lead in this month's publication with remarks, being the substance of a lecture, on the general structure and habits of invertebrate animals, illustrated with a tabular view in seven figures, ingeniously devised. Notes, by Mr. Proctor, on an ornithological tour in Iceland, are followed by a notice of rare birds obtained in the winter of 1837-8, by Mr. Blyth, and then by Mr. Torre's list of birds found in Middlesex, amounting to one hundred and thirteen species. Next in order, are the chapters of correspondence and criticism, and the extracts from foreign periodicals, consisting of sketches on the hybernation of swallows, on the fresh-water and marine sponges, on a hanging bird's nest framed of silver wire, on the feeding of silk-worms on the fecula of potatoes, on a Malayan albino, on vegetable acids, on a fossil salamander, on a skeleton of the narrowmouthed mastodon, and on vases discovered in the tombs of Santorini.Among the proceedings of natural history societies, those of the entomological, horticultural, and zoological, are briefly noted. At the ornithological Mr. Blyth exhibited specimens of the three British geese allied to the domestic breed, and then offered a variety of observations on them, and on some rare birds obtained in the London markets; and, at the botanical, a paper of Dr. Wallis' was read on the genus Myosotis: he advances an ingenious suggestion concerning the M. arvensis and M. sylvatica and their specific distinctions. The Miscellanies are numerous and varied, and not unimportant; and, with two reviews, the August is concluded. XXIV. Under six distinct heads, Mr. Watson describes the effect of the winter of MDCCCXXXVII on vegetation in the neighbourhood of Thames Ditton: this is a truly practical article, the result of observation. It is followed by an anonymous communication on the sources of heat which influence climate: the writer traces this heat to the calorific power of the solar rays, the temperature of the planetary spaces, the heat of the earth's central mass, and the caloric changed by every variation from one state to another. Next in course, Mr. Wood explains his views respecting the exciting causes of varieties in birds and other animals; and his paper is followed by that of Mr. Hall, on the habits and peculiarities of British plants, and on the derivations of their Latin names. Mr. Neville Wood then gives a " condensed analysis” of Part xv1 of Gould's "Birds of Europe," and the prologue to his article exhibits the prominent features which distinguish Mr. W.'s lite rary character-juvenile vanity, heartless illiberality, and false representation. Mr. Pigott favours the editor with a correspondence professing to be general remarks on the Naturalist and natural history; and the chapter of criticism is occupied by a "few words" of Mr. Lankester's on the formation of pearl, and by some words of his on the Linnæan and natural systems of botany. At the Liverpool natural history society, the discovery of a large slab of sandstone, "having upon its lower face a number of casts of feet in high relief," was taken into consideration, and a report of the discussion stands here as a "proceeding" of that institution. The Miscellanies make a chapter of selections from Withering's Botany, the Athenæum, and other periodicals; and with its September number the second volume of the Naturalist is concluded. 9 o'clk, a.m. Dew Point, deg.
