FOREWORD TO SECOND EDITION 



This book is written to fill a demand from veterinary^ stu- 

 dents, students in poultry husbandry courses at agrieultural 

 colleges, veterinary practitioners and 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 results of experimental research in the laboratory of path- 

 ology of the author and of many other investigators. 



For the purpose of simplification, the synonyms are given 

 for the various names of diseases. Then follow, in order, the 

 cause, or causes, the symptoms, the conditions found upon 

 Dost-mortem examination, and lastly the treatment and means 

 of eradication for each disease. 



The author is indebted to Dr. D. :\I. Campbell, editor of the 

 American Journal of Veterinary Medicine, for helpful sug- 

 gestions as to arrangement and other matters. 



The first edition being exhausted in so short a time is evi- 

 dence that it met the expectations of the author aiid the pub- 

 lisher—that it filled a real need. This second edition has been 

 thoroughly revised and brought down to date. IMuch new 

 information in the chapters on anatomy of the fowl, foods 

 poisonous to fowls and poultry materia medica has been 



added.
