Thirty-five cases had been reported up to the time I left the 

 islands. Probably many more cases had occurred. 



Chicken-pox was present several years ago. No histories 

 were secured suggestive of typhoid fever, diphtheria, or scarlet 

 fever. Cholera was apparently present in 1902. Dengue fever 

 occurs from time to time according to the testimony of the 

 civujano administrante. Beriberi is apparently absent. No 

 cases suggestive of this disease were seen, and no suspicious 

 histories were obtained. The last case of smallpox seems to 

 have been in 1896. About 2,000 persons were vaccinated while 

 I was in the islands, and sufficient virus to vaccinate 2,000 

 more was left with the cirujano administrante on May 7. This 

 quantity was sufficient to bring the vaccination up to date. Three 

 cases of insanity were seen, and the history of 4 others secured. 

 No case of yaws was seen. 



Since 1906 several lepers have been taken from the Batanes 

 by the Bureau of Health. Some of these were native to the 

 islands, while others were fugitives from northern Luzon. No 

 case of leprosy was found during my investigation. 



One apparently typical case of migraine was found. The 

 patient stated that a cousin and an aunt were similarly affected. 



One case strongly suggested the occurrence of cerebro spinal 

 meningitis in the islands about four years ago. The patient 

 was a boy 5 years old who had been quite normal until one 

 year of age, when he became acutely ill. His temperature 

 was very high, tremors and convulsions were common; and his 

 grandmother recognized the opisthotonus condition at once and 

 said the child had such a symptom. She also stated that 

 about 10 other children had the same disease about the same 

 time and that they all died. The head, body, and upper ex- 

 tremities of the patient were well developed. The lower ex- 

 tremities were considerably undersized. The patient had never 

 been able to walk, and he was mentally very backward, being 

 able to talk only with great difficulty and his vocabulary was 

 limited. 



Venereal disease is rare. Not one case of undoubted clinical 

 syphilis was seen. Some of the old ulcerous cases may have 

 been syphilitic, but a Wassermann reaction would have been 

 necessary to render a positive diagnosis. Four cases of gonor- 

 rhoea were found, 2 of which were in Filipino cooks who had 

 recently arrived from Manila. 



Death claims yearly its victims among the new born and 

 mothers because of the lack of medical attention during par-
