"As a resume of what is at present known on the subject of fossil remains, it is worthy to be a companion to the author's 'Descriptive Geology,' a work of which we have spoken in the highest terms. This volume is illustrated in the style of all Van Voorst's Natural History works, and that is sufficient recommendation. Our extracts will convey a notion of the style of the work, which is, like all that Professor Ansted has written, clear and pointed.--_Athenæum._ * * * * * CHEMISTRY OF THE FOUR SEASONS, SPRING, SUMMER, AUTUMN, AND WINTER. AN ESSAY, PRINCIPALLY CONCERNING NATURAL PHENOMENA, ADMITTING OF INTERPRETATION BY CHEMICAL SCIENCE, AND ILLUSTRATING PASSAGES OF SCRIPTURE. BY THOMAS GRIFFITHS, Professor of Chemistry in the Medical College of St. Bartholomew's Hospital, &c. In one large royal 12mo. volume, with many Wood-Cuts, extra cloth. "Chemistry is assuredly one of the most useful and interesting of the natural sciences. Chemical changes meet us at every step, and during every season, the winds and the rain, the heat and the frosts, each have their peculiar and appropriate phenomena. And those who have hitherto remained insensible to these changes and unmoved amid such remarkable, and often startling results, will lose their apathy upon reading the Chemistry of the 'Four Seasons,' and be prepared to enjoy the highest intellectual pleasures. Conceived in a happy spirit, and written with taste and elegance, the essay of Mr. Griffiths cannot fail to receive the admiration of cultivated minds; and those who have looked less carefully into nature's beauties, will find themselves led on step by step, until they realize a new intellectual being. Such works, we believe, exert a happy influence over society, and hence we hope that the present one may be extensively read."--_The Western Lancet._ * * * * * PHILOSOPHY IN SPORT, MADE SCIENCE IN EARNEST; BEING AN ATTEMPT TO ILLUSTRATE THE FIRST PRINCIPLES OF NATURAL PHILOSOPHY, BY THE AID OF THE POPULAR TOYS AND SPORTS OF YOUTH. FROM THE SIXTH AND GREATLY IMPROVED LONDON EDITION. In one very neat royal 18mo. volume, with nearly one hundred illustrations on wood. Fine extra crimson cloth. "Messrs. Lea & Blanchard have issued, in a beautiful manner, a handsome book, called 'Philosophy in Sport, made Science in Earnest.' This is an admirable attempt to illustrate the first principles of Natural Philosophy, by the aid of the popular toys and sports of youth. Useful information is conveyed in an easy, graceful, yet dignified manner, and rendered easy to the simplest understanding. The book is an admirable one, and must meet with universal favour."--_N. Y.
