MEDICAL SURVEY OF THE TOWN OF TAYTAY. 



277 



examined of 56.4 per cent. Only two persons showed such h)w averages 

 as 15 and 20 per cent; the first one was in a chikl 2 3^ears old, suffering 

 from a heavy infection of Ascaris : and the second in a girl of 19 years, 

 suffering with chlorosis. 



Among the 11 cases of malaria an average of 75.9 per cent of liEemo- 

 gloliin was found, the lowest registering (iO per cent and the highest 90. 

 Among 572 persons in whom the percentage of haemoglobin fluctuated 

 between fid and 90 per cent, we found an average of 56.4 per cent. The 

 relatively higii percentage of hsemoglobin found among the malaria cases 

 was probably due to the fact that the majority of them were primary 

 infections in whom olygochromemia was not marked. 



To our great regret counts of the red blood corpuscles and of the 

 leucocytes, owing to lack of time, were performed only in very few cases. 

 In our opinion the number of red blood corpuscles in the majority of the 

 Filipinos of Taytay is undoubtedly below the number considered normal 

 for the inhabitants of temperate climates. 



Fresh blood smears from 742 individuals were examined, but no otlier 

 parasite was found in these specimens, excepting the parasite of malaria 

 which was encountered in 16 cases. 



The sjairochfeta of relapsing fever was sought for in the blood of all 

 the fever patients who came to our dispensary and in many others who 

 were confined to their homes, but was not found. 



A differential count of the leucocytes was made in 129 persons, as 

 shown in the following table.

From this table it may be seen tiiat if we adopt as a standard the figures 

 given by Cabot and Da Costa, a small increase will l)e noticed among the 

 number of the lymphocytes and a decrease in tbc polymorphonuclear 

 cells, -while the large monuclears and the inastcells remained normal. 

 The percentage of eosinophiles is also increased in the majority of cases 

 above normal, and in some cases it rose as high as 3fi.fi per cent ; this 

 marked eosinophilia is ascribable to the fact that 94 per cent of the 

 population are affected with intestinal jjarasitcs and a large percentage 

 suffer from various skin diseases.
