BLOODWORMS. 151

 little patient admirably. It may be said, indeed, 

 that but for the fact of the hsematuria no ordinary 

 observer would suppose that at the time I last saw 

 her the child was otherwise than in a perfect state 

 of health. 



This case, gentlemen, is a most remarkable one ; 

 for, apart from the special interest attaching to the

 you will have noticed that the child was invaded, 

 certainly by two, if not by three, other forms of 

 parasite. She had been efficiently treated for 

 lumbrici by Dr. Lyle ; and it was alleged that she

 borne out by the fact that I discovered numerous 

 eggs of a species of nematode in the urine. On one 

 occasion I found six ova, and on another about fifty. 

 Had only one of the three adult nematodes from 

 the urine been preserved for examination, it would
