 '' The result is a book treating of a large variety of subjeots'ftnd all written by specialists who know 

 their subjects so thoroughly that they can speak with authority. Under these conditions not only 

 are the subjects eflSoiently handled, but there is a minimnm of error, since no part of the book is 

 the product of one writing except on familiar ground. ... 



The book becomes a most extremely valuable addition to the literature of bacteriology, perhaps 

 the most valuable single publication that hai yet appeared. The various authors are particularly 

 to be thanked for the time and care taken in what must at best be a work of love."

 uate student, and serves as a framework around 

 which may be grouped the facts learned in the lab- 

 oratory. No attempt has been made to describe 

 every species in detail but rather to outline the 

 general morphology of all vertebrates.

 is not troubled with a diversity of opinions, whilst a dogmatic style is adopted throughout."
