THE MICROSCOPE. 235 



Insects Injurious to Fruits. By William Saunders, F. R. S. C, etc. 

 Pp. 436. Figures 440. J. B. Lippincott & Co., Philadelphia. 1883. 



The author commences with a description of those insects 

 injurious to the apple, the pear, the plum, the peach; and, devoting 

 a chapter to each fruit, concludes with the olive and the fig. We 

 have noticed over twenty fruits described with their own particular 

 insects. Take for instance chapter I, on The Apple. The author 

 describes first those insects that attack the trunk, then follows in 

 order those that attack the branches, the leaves and the fruit. This 

 classification will greatly facilitate the determination of any injuri- 

 ous species. 



The remedies that have been the most successful in subduing 

 each individual species are fully discussed and described, enabling 

 the reader to decide at once as to the best methods to be employed. 



The work is interesting to students of entomology, and invalu- 

 able to all fruit-growers, whether or not they have many or few 

 acres. Any person who may own a few vines or trees will find this 

 a handy book to have about at the right time. 



New Text-Book of Geology. By James G. Dana, LL. D., author of "A 

 Manual of Geology," etc. Fourth edition, revised and enlarged. Pp. 412. 

 450 figures. Ivison, Blakeman, Taylor & Co., New York and Chicago. 

 1883. 



This text-book is after the general plan of Professor Dana's 

 "Manual," and is certainly an American book. The illustrations 

 are largely from American facts, as the geysers of the Yellowstone, 

 the Mammoth Cave of Kentucky and th ; canons of the Colorado. 



This edition has about fifty pages more than the preceding one, 

 thus allowing of fuller and more complete accounts. 



The kinds of life which contribute to rock-making, the geo- 

 graphical distribution of marine species and the depths of the seas 

 are some of the topics discussed in this edition for the first time. It 

 does not take the place of Professor Dana's large manual, yet it is 

 evident from the number of editions sold that it is one of the best 

 text-books of its kind for schools and academies.
