_INSECT LIFE._ By JOHN HENRY COMSTOCK, Professor of Entomology in Cornell University. With Illustrations by Anna Botsford Comstock, member of the Society of American Wood Engravers. 12mo. Library Edition, cloth, $2.50; Teachers’ and Students’ Edition, $1.50. “Any one who will go through the work with fidelity will be rewarded by a knowledge of insect life which will be of pleasure and benefit to him at all seasons, and will give an increased charm to the days or weeks spent each summer outside of the great cities. It is the best book of its class which has yet appeared.”—_New York Mail and Express._ “The arrangement of the lessons and experiments and the advice on collection and manipulation are only some of the very admirable features of a work that must take first place in the class to which it belongs.”—_Philadelphia Press._ “The volume is admirably written, and the simple and lucid style is a constant delight.... It is sure to serve an excellent purpose in the direction of popular culture, and the love of natural science which it will develop in youthful minds can hardly fail to bear rich fruit.”—_Boston Beacon._ _OUTLINES OF THE EARTH’S HISTORY._ By Prof. N. S. SHALER, of Harvard University. Illustrated. 12mo. Cloth, $1.75. “Any one who reads the preliminary chapters will not stop until he has read the entire book. The subject is certainly one of supreme interest, and it would be hard to find any one more competent to write about it than Professor Shaler.”—_New York Herald._ “Professor Shaler fortunately possesses a popular style, and what he writes on a scientific topic is entertaining as well as instructive. This book is illustrated with a number of splendid full-page cuts, which admirably illuminate the work.”—_Boston Globe._ “Professor Shaler, of Harvard, in the well-worded text and the handsome illustrations, presents an interesting and instructive volume to the students of physiography. It is a simple study of the earth’s history, revealing Nature’s processes and its continuous and increasing, unceasing energies. It is well calculated to arouse an interest in geological study, as it furnishes the key to unlock some of the great mysteries the student meets in this broad field of science.... He explains many curious phenomena. The work is very free from technicalities, and is so plainly told as to be easily understood by every intellectual reader.”—_Chicago Inter-Ocean._ APPLETONS’ HOME-READING BOOKS. Edited by W. T.
