The results of this limited number of examinations show a 

 percentage of infections with intestinal parasites not varying 

 materially from that obtained by other investigators in the Phil-

 examinations are the relatively high percentages of infections 

 with Strongyloides stercoralis, Dibothriocephaius latus, and Ba^ 

 lantidium coli, but the number of persons examined is too small 

 for one to lay any great stress on the results.

By W. E. Musgrave, A Vazquez, B. Gutierrez, and Seth L. Cox 



Of the total population of about 3,200 employees, together 

 with women and children, of the San Jose Estate, 1,110 persons 

 were examined clinically. The examinations were more or less 

 superficial in character, but sufficient time was taken to deter- 

 mine, with a fair degree of accuracy, any gross pathological
