chnicalities. 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.--_Athenaeum._

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._
