Filipino children. While general sanitary conditions are largely 
responsible for this, still we believe that so far as the children 
are concerned the problem is one of education of the masses in 
the simpler principles of domestic hygiene. This will be a 
formidable task, but it is one on which the Government may 
with profit expend large sums of money. It calls for the devel- 
opment of the principles of parasitism and preventive medicine 
on a particularly high plane in the Philippine Islands where para- 
sitic infestations are more common probably than in any other 
country from which there are records. 
Endolimax nana and Dientameba fragilis are reported for 
the first time from the Philippine Islands. Eutrichomastiz is 
provisionally reported.
