ous to that of probing with the wire; out, as far as 

 I can recollect, I never cured one by that means. 



I remember of once conversing with him on the 

 subject, when he told me that he seldom or never 

 failed of curing* them upon their own farms; but 

 that, in sundry neighboring farms, he rarely cured 

 any. From this, it would appear that on different 

 soils, the animals are differently affected, 1 am 

 now convinced that he must generally have inser- 

 ted the pin so far as to penetrate the bottom of the 

 sac, which 1 never had the sense to try, and 

 which, if we reason from analogy, must prove as 

 effective, and less hazardous than the other: for it 

 appears to me, that, in order to ensure a recovery, 

 it is necessary that the bottom, or lowest part of 

 the sac, be penetrated. 



Undoubtedly, the best mode of curing this dis- 

 ease would be, to extract the sac, and all that it 

 contains, entirely. There is little doubt that, if 

 this were performed by gentle and skilful hands, 

 it would prove the most effectual cure; but as it is, 

 r can attest that it seldom proves successful. The 

 shepherds have not skill and ingenuity sufficient 

 to close the skull properly up again, or s*^; l it in 

 such a manner as is requisite to defend it from ex- 

 ternal injury; of course, I would rather recom-
