" There were no deaths from undetermined fevers. 



; Table lY shows that there has been a constant' though low, admission 

 rate for typhoid among the Philippine Scouts since their organization. 

 It is certain that the diagnoses for sick Scouts are less thoroughly worked 

 up than are those of the white troops because of racial peculiarities 

 and the diiBculty of understanding their language, and also because of 

 the fact that many of the Scout org-anizations are at small and isolated 

 posts with meager laboratory facilities. Therefore, some cases of typhoid 

 may lie hidden in the great mass of admissions for malaria and undeter- 

 mined fevers, only the most characteristic cases being correctly diagnosed. 



Since most of the Scouts are at posts where they come: in contact with very 

 few white men, it is almost certain that, they pick up their infection at the post 

 or in the country surrounding and that the disease is not imported from !the 

 United States as might be urged in the case of the white Soldiers. 



The lesser incidence of typhoid among the Scouts* as compared with American 

 troops corresponds with Rogers' experience with native troops in India. He 

 attributes tliis difference to the influence of typhoid in childhood. 



DISTRIBXJTION OF TYPHOID FEVEE IN THE PHILIPPINES. 



The distribution of typhoid throughout the Archipelago, in so far as it has 

 come under the notice of the Army medical officers, is shown in Table V.
