PREFACE TO THE FIRST EDITION. 



IN this manual the writer has endeavored to describe 

 the laboratory technique which the beginner must follow, 

 and at the same time to give a concise summary of the 

 facts in bacteriology most important to the physician. In 

 preparing a work of this character, which claims to be 

 nothing more than a compilation, the standard text-books 

 were necessarily consulted freely. On account of the need 

 for brevity it has, in most cases, been impossible to men- 

 tion authorities. 



The writer is glad to have this opportunity to acknowl- 

 edge his obligation to the works of Sternberg, Fliigge, 

 Gunther, Eisenberg, Abbott, W. H. Park, Muir and Ritchie, 

 Vaughan and Novy, and McFarland; and to numerous 

 papers by Professor Welch and others. It is thought that 

 the chapters on Germicides, and Surgical Disinfection, by 

 Drs. Thos. B. Carpenter and Marshall Clinton, will be use- 

 ful not only for the information presented in them, but 

 especially in correlating that information with the facts of 

 bacteriology.
