K,B,8 Barber et al.: Malaria in the Philippines 191 
In proportion to the population a larger number of acute cases 
of malaria in Iwahig come from the outlying barrios than from 
the central or better improved part of the colony. This is prob- 
ably due in part to the more exposed situation of the newer 
barrios, and possibly in part to the fact that the quinine prophy- 
laxis practiced in the colony (5 grains per day to each person) 
could not be so rigorously carried out in the barrios. In order 
to give some idea of the amount and origin of acute cases of 
malaria, a record is given in Table IV of the admission of fever 
cases to the colony hospital during three days.. The micro- 
scopical examinations were made by Barber.
