 entire secret of medicine. Skill in application is obtained 

 by the study of the symptoms of the sick man or

Materia Medica. 



A concise Materia Medica of the remedies prescribed 

 in this book will be found on its last pages, and a study 

 of this part is recommended to all who would be suc- 

 cessful in treating the ailments of their fowls. This 

 Materia Medica is a record of the symptoms produced 

 by the drug taken in excessive doses by men in a state 

 of health. 



The classification of diseases is, at best, but mere 

 generalization. Take, for instance, " colds ;" a dozen 

 people may come together, each suffering from a u cold/' 

 yet the symptoms of no two of them be exactly alike. 

 So with the diseases of fowls described in this book ; 

 each one is named as well as may be, and the best 

 known remedy prescribed, and it may be administered, 

 as a rule, with great profit in the saving of the lives of 

 poultry, yet an intelligent study of the symptoms of the 

 affected fowls, and comparison of them with those of 

 the different medicines, will greatly aid in the work.
