third part is given up to a consideration of Insecticides, Preven- 

 tives and the machinery used by the economic entomologist. 

 An interesting chapter treats also of Predaceous and Parasitic 

 Insects and P^ungous Diseases. 



Prof. Smith's book is an octavo volume of 481 pages 

 published by the J. B. Lippincott Co., of Philadelphia, and there- 

 fore well printed on good paper and well got up generally. 

 There is a profusion of excellent illustrations (483), many of 

 which were prepared specially for this work. 



We feel assured that this useful work by our esteemed 

 corresponding member will be gladly welcomed by the large 

 number of farmers, gardeners and students who are so frequently 

 applying to booksellers and others for a work of this nature upon 

 economic entomology. J. F.
