 good effects continued, and I believe that they do 

 so to this present hour. 



Such are some of my experiences with this 

 troublesome disorder, and I think you will admit 

 that guided by a correct knowledge of the more 

 recent contributions to the natural history of this 

 parasite, we have at length arrived at a better 

 system of counteracting and checking, if not of 

 absolutely curing the disease which it occasions. 

 Personal cleanliness is certainly essential. A recent 

 writer, who is at the same time a very accurate
