have followed the method adopted in those 

 times of epidemic and epizootia when the 

 small-pox is raging. On those occasions, we 

 subject our sick patients to vaccination or 

 re vaccination ; we inoculate the variola in our 

 sheep threatened with the contagion ; we 

 pursue the same course in cases of epizootia, 

 of peripneumonia. And truly, that which it 

 is reasonable to do in one case may be gene- 

 ralized and applied to a greater number. 



The experiment we have suggested might, 

 perhaps, have been long and difficult, nay, 

 even costly, but we should have established, 

 after a certain time, the rational method of this 

 preventive treatment, and have distributed the 

 same throughout the country. Veterinarians 

 would have formed in particular districts their 

 centre of operation, in which the preventive 

 virus might have been produced, and they 

 might have gone from farm-house to farm- 

 house to inoculate all the cattle within them. 



Prom these facts and observations made by 

 the physicians, precious documents would have 

 been derived ; and if, contrary to all expecta- 

 tion, success had not justified every hope, we 

 should have bequeathed to future generations
