30 The Microscope. 



those who have no time for voluminous works, and he succeeds 

 in putting what he has to say into clear language and into brief 

 compass. The author pretends to no originality in the first part, 

 which outlines the achievements of science, and he scarcely 

 reaches any in the second, which deals with the revolution these 

 achievements are supposed necessarily to effect in religion. He 

 depends almost as fully on Huxley and others for his opinions 

 as for his facts. He states the results of science with tolerable 

 accuracy, though he accounts as scientific a few things which 

 others as well qualified to speak would regard as speculative. 

 His conclusions respecting the modifications of religious faith 

 by the progress of science are somewhat radical, and would be 

 called in question, not only by theologians, as he should expect, 

 but by many learned laymen as well. Altogether, it may be said 

 that this work, whose spirit and tone are admirable throughout, 

 is a valuable contribution to recent literature ; and while it would 

 not be a safe guide for those who depend on authority, it may 

 be commended to those who have intelligence and independence 

 enough to think for themselves.

 children depicted with a grace that is charming. The whole

Invertebrate dissections. — By Henry L. Osborn, Ph. D. 

 •Square 16mo., pp. 36. Published by the author, Hamline, 

 Minn. Price 40 cents. — " Experience has demonstrated," says 

 Prof Osborne, " that the beginner in Zoology can learn a great 

 deal with such simple tools as scalpel and hand lens, which can 

 be had by anyone, and with these penetrate far into Nature's 

 secrets." This is the key-note of the little book that is all work 

 for pocket lens and naked eye, with those explicit directions and
