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 xvi 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. 3 o'clk, p.m. Dew Point, Atchd.
