6 Veterinary Medicine. 



tinguishing the infection itself and banishing it for all time from 

 a country. To deal with parasites so as to cut off their sources of 

 survival, and extirpate them from a locality, a fuller knowledge 

 of their life history is demanded than for simple parasiticide medi- 

 cal treatment. The broader view and the more economic preven- 

 tion must therefore be the prerogative of the scientist, and the 

 fact that each parasite or group demands a different management, 

 establishes a greater call for a profound study of the subject. 

 Here as elsewhere knowledge is power, and should be recognized 

 and appreciated as such.
