posed to put them in the best possible condition for 

 withstanding the disease. Under this plan it was 

 found that the vast majority came through the com- 

 plaint, and were never afterwards liable to its inva- 

 sion. But we give this important result in our au- 

 thor's own words. " The beneficial results are too 

 important to our farmers that they should ever be 

 induced to give up this easy method of saving 

 their stock. They had remarked that calves dropt 

 by cows which had undergone the distemper, had in 

 general far less violent attacks as the results of the 

 inoculation ; and that they recovered in much 

 greater numbers than the calves of other cows. Con- 

 fining, then, the experiment to this class, under this 

 combination of circumstances, the disease was so 

 mild, that the farmers often doubted if the calves, 

 though inoculated, really underwent the disease. 

 I have sometimes myself inoculated between two 

 and three score at a time, and observed the calves 

 disporting themselves gaily in the stable-yard. Those 

 of them which were most seriously affected, would 

 withdraw for a time, but speedily returned, and thus 

 they all passed safely through the disorder, so that 

 scarcely one in a hundred perished. Sometimes, 

 indeed, it, happened, that when the inoculated dis- 

 ease was not well marked, or where perhaps the 

 operation had altogether failed, these calves were af-

 became its victims, while feeding with herds which
