Surveys to determine the incidence of intestinal parasites are 
not a novelty in the Philippine Islands. Several excellent sur- 
veys have been made, the results of which are familiar to workers 
in tropical medicine. So far as we have knowledge, however, 
nothing approaching a survey by recent methods has been made 
among young Filipino children. This study can hardly be said 
to rank as a survey, for the number of cases considered is too 
small, but they have been studied with such care and thorough- 
ness as to warrant us in the belief that we have missed few if 
any of the latent positives. One hundred twelve cases were 
studied, but twelve of these were dropped because of the death 
or discharge of the patient before investigation of the case was 
complete. The study of these cases has involved the examina- 
tion of more than four thousand five hundred microscopic prep- 
arations and more than five hundred stool concentrations. 
In undertaking this study we believed it possible that we 
might secure some suggestive data that might lead to an in- 
vestigation, on a more extensive scale, into the possible influence 
on infant mortality in the Philippine Islands of infestation by
