With advancing knowledge of veterinary medicine the subject 

 of prophylaxis is steadily assuming a more important place, and 

 especially in the classes of enzootic and epizootic diseases. In- 

 deed for the fatal infectious diseases of animals one can fairly esti- 

 mate the medical intelligence of the people by the extent to which 

 therapeutic treatment is still allowed. With economy as the 

 great central object of veterinary medicine, the problematic re- 

 covery of the few can never balance the assured preservation of 

 the many. But this subject belongs to contagious diseases to 

 which the reader is referred. 



In enzootic affection, improvements in soil, water, exposure, 

 buildings, and other local unhygienic conditions, are the final 

 ends to be sought, according to the particular nature of the pre- 

 vailing disease. 



So in sporadic diseases the correction of faults in breeding, 

 hygiene, diet, water, work, harness, exposure, buildings, venti- 

 lation, etc. , are called for in different cases as will be noted under 

 the individual diseases.
