"The science of geology largely engages the attention of the public; but persons are frequently deterred from the study of it by the dry and tedious style of writers dedicating their talent to its exposition. Professor Ansted has supplied a book which meets the public want.... The chapters relating to agricultural geology have an especial interest for farmers; but the whole are deeply interesting and worthy of recommendation."-News of the World.

"Professor Ansted takes in hand a subject of some difficulty, but of universal importance. In this he describes the different kinds of mineral veins, their contents, and the methods adopted to extract those contents, and thus fitly concludes his labours in elucidation of the practical application of geological knowledge to economic purposes, especially in connection with the arts."-Daily News.

Metamorphoses of Man and Animals.

Describing the changes which Mammals, Batrachians, Insects, Myriapods, Crustacea, Annelids, and Zoophytes undergo whilst in the egg; also the series of Metamorphoses which these beings are subject to in after-life.

Translated by HENRY LAWSON, M.D. Crown 8vo. cloth, price 6s.

"We have already said enough to show that the essay which Dr. Lawson has introduced to us in an English garb is one which marks a new era in the history of Embryology, and which presents to both general and scientific readers information which has been hitherto confined to the realms of dusty periodicals of all languages. The Metamorphoses' is a work which tends to elevate the science of Biology, and deserves the attention of all classes of cultivated readers.”—London Review.

"It is crammed with starry plates on wood and stone, and among the celestial phenomena described or figured, by far the larger number may be profitably examined with small telescopes, and none are beyond the range of a good threeinch achromatic. The work also treats of the construction of telescopes, the nature and use of star maps and other subjects connected with the requirements of amateurs.... The book is full of useful and interesting information,' and will form a valuable companion to the various admirable handbooks for which Mr. Hardwicke enjoys so good a reputation.”—Illustrated Times.

"Nothing so well calculated to give a rapid and thorough knowledge of the position of the stars in the firmament has ever been designed or published hitherto.
