PREFACE 



This book is written to fill a demand from 

 Veterinary students, students in Poultry Hus- 

 bandry courses at our Agricultural Colleges, for 

 Veterinary practitioners and for others interested 

 in the scientific treatment of poultry diseases. 



An effort has been made to make the language 

 so plain that all can comprehend the subject- 

 matter, which is a summary of thoughts from 

 experimental research in the Laboratory of 

 Pathology of the author and of many other in- 

 vestigators. 



For the purpose of simplification, the synonyms 

 are given for the various names of diseases. Then 

 follow, in order, the cause, or causes, the symp- 

 toms, the conditions found upon postmortem ex- 

 amination, and lastly the treatment for each 

 disease. 



The author is under very great obligations to 

 Dr. D. M. Campbell, Editor of the Ameeican 

 JouENAL OF Veteeinaey Medicine, f or editing and 

 arranging his laboratory notes on this subject 

 into a related whole, as here presented, and for 

 the section on Sanitation and some other portions.
