It must be understood that the part of Mindoro under con- 

 sideration formerly was practically uninhabited and that the 

 population of 3,200 people represents emigrants from practically 

 the entire Philippine Archipelago, so that the examination of 

 these people, except in those diseases definitely contracted after 

 arrival at Mindoro, represents, to a certain degree, an index of 

 conditions found throughout the country. 



The principal points in the physical examination of this entire 

 group of persons is indicated below. 



MAL.\RIA 



By reason of incidence and general morbidity and mortality 

 effect upon the population in general, malaria ranks third in the 

 sanitary problems in the Philippine Islands, infant mortality 

 and tuberculosis holding the first and second places, respectively. 



The distribution of malaria is very general. However, there 

 are places in the Islands where the disease is unknown, and 

 there are a number of other places where the infection is very 

 severe, is constantly present, and where the disease has existed 

 as far back as we have any record of the country. 



Of all the infected centers, the west coast of Mindoro is popu- 

 larly considered to be the worst. As is shown in other places in
