PREFACE. 



In undertaking the translation of MM. Mosselman 

 and Lienaux's ^'3fanuel de 31icrobiologie Veterinaire" 

 my object has been to supply English speaking veteri- 

 nary students and practitioners with a work on Bac- 

 teriology which seemed specially adapted to their 

 needs. The book is small, but it conveys more in- 

 formation on the etiology of the infectious diseases 

 of animals and the biology of the germs associated 

 with them than any other single work in our lan- 

 • guage. Unlike other works on Bacteriology accessi- 

 ble to readers of English only, the Microbiology of 

 animal diseases is treated of as the essential part of 

 the work, that of diseases of mankind only incident- 

 ally referred to. The completeness and accuracy as 

 to details with which it discusses the modes of prop- 

 agation of some of our most important diseases and 

 the general conditions under which these diseases 

 occur, ought to recommend the book to practical 

 veterinarians, who are presumably more interested in 

 the ascertained facts in regard to any disease than in 

 the individuality of the germ which occasions it. 



The book is not intended for a laboratory manual, 

 consequentl}', the technique of staining and cultiva-
