STUDY OF INTESTINAL PARASITES. 



79 



Eissler and Gomez were from the examination of one cover-slip prepara- 

 tion of each case. However, my results may be compared with theirs 

 according to the testimony of a Filipino boy who made many of the prep- 

 arations at Las Pinas, a large number of the microscopic examinations 

 at Ti^guegarao and Santa Isabel, and practically all of my own prepara- 

 tions, since no more fcecal material was used in two of my prepara- 

 tions than in one of Eissler and Gomez.

PHILIPPINES. 



The results obtained are compared in Tables II and III, respectively, 

 with those in other parts of the Philippines as to the number of infections 

 found and the various parasites present.
