"In place of a mere repetition of methods and enumeration 

 of species, Professor Hueppe has grappled with the fundamental 

 questions concerned, and has in clear language given a cogent, 

 philosophical and scientific account of bacteria and their rela- 

 tions to the processes with which they are said to be associated. 

 . . . . It is the work of a master of the subject, who is not 

 only a scientific man in the sense of being an ol^server, but also 

 in the sense of having a true philosophical mind." The Lancet. 



"To one who wishes to know what bacteriology has accom- 

 plished and what problems are still undergoing solution, no- 

 thing can serve better than this outline of Professor Hueppe."
