necessarily brief chapters are supplemented by excellent bibliographies. Every 
beginner in entomology who embarks upon experiments to ascertain the effects of 
heat, light, and changes of food upon insects, or attempts the breeding of hybrids, 
will find this book indispensable. Not only will it tell him what others have done in 
the same line; it will also give him a broad idea of modern experimental research 
and its attaineil results, and awaken in him a new zeal for the investigation of nature. 
For very practical service in enal)ling a novice to identify his captures or ascertain 
food-plants, Mr. F'orbes’s “Field Tables of Lc|)ido]>tera will be found of value. 
As now pul)lished in neat ])amphlet form, these tables are an amplification of those 
given in Dr. Hodge’s “Nature Study and Life.” Though marred by serious typo- 
graphical errors, and in places (as in the (flossary) l)y incom})letene.ss of statement, 
the work exhilfits many helpful features and much iiigenuity of arrangement.
