died of cholera. The size of the adult parasites being greater 

 than the ampulla of Vater or the appendiceal opening, did they 

 go in when they were young, as believed by Perroncito,(4l) has 

 there been a previous dilatation of these ducts before their migra- 

 tion, or were these migrations post mortem? 



This migratory activity seems also to be stimulated by hunger 

 of the host ; for during my service in the department of medicine, 

 Philippine General Hospital, I used to treat children, and adults 

 as well, with symptoms of peritonitis, who proved to harbor a 

 great number of ascarides, by Murphy's peritonitis treatment and 

 saw the subsidence of the symptoms and passage of the worms 

 without the use of any drug.

As we see, Ascaris is the worm that first invades the human 

 alimentary tract and the one that infests the most, being found 

 alone in 112 cases, and if we include those cases where Ascaris 

 was found with other intestinal parasites, the number of children 

 infested will rise to 152, or 95,5 per cent. 



Garrison and Llamas (19) found 95 per cent of children in
