The object of this work is to present to the general reader the chief results of Geological investigation in a simple and comprehensive manner. The author has avoided all minute details of geological formations and particular observations, and has endeavoured as far as possible to present striking views of the wonderful results of the science, divested of its mere technicalities. The work is printed in a handsome manner, with numerous illustrations, and forms a neat volume for the centre table.

"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.
