fellows. While filariasis of itself is apparently in no way incompatible 

 with the enjoyment of excellent health, the possibilities of its sequelae 

 should not be lost sight of. The discovery and rejection of these men 

 before enlistment would be the most satisfactory method of prevention. 



VIII. SUMMARY AND CONCLUSION. 



It is evident that filariasis is not as rare a disease in the Philippine 

 Islands as has been supposed. From our own observations and the fact 

 that seven out of nine previously reported cases of filariasis among the 

 native population have been natives of the Bicol provinces, we are 

 convinced that in these districts we have the largest endemic focus of 

 filarial disease, with, perhaps, the exception of Davao, that exists in 

 these Islands. It is our belief that the microfilaria found in the cases 

 here reported are the Microfilaria bancrofti, more commonly known as 

 the Filaria nocturna, and that this is the common filaria of the Islands. 

 It is also our belief that all microfilaria heretofore coming under our 

 observation have been examples of this same species. 



In conclusion we wish to express our appreciation of the assistance 

 given us by the governor of Albay Province, to the various municipal 

 physicians of the Bicol provinces in general, and to Captain C. C. Collins, 

 Medical Corps, United States Army, medical officer at Camp Daraga, 

 who, by his zeal and energy, assisted us greatly in collecting the material 

 for this investigation.
