and here the economic side of the question is brought out more 

 fully. The book contains 410 pages and is profusely illustrated, 

 although but few of the cuts are original. 



The text-book is accompanied by a laboratory manual of 276 

 jjages which gives directions chiefly by means of numerous brief 

 questions which the student is to answer by means of direct 

 observation. Directions are given for general studies in ecol-

 studies of the crayfish, spider, insects, fish, frog, turtle, bird, 

 rabbit, man. Protozoa, Porifera, Coelenterata, Echinodermata, 



Annulata, and Mollusca.

 idiosyncracies. This is a fascinatingly interesting book, and 

 ought to be read by every student of the natural sciences,

 omission; we have such sketches from Otto Brunfels to Lin-
