Dr. Carlos J. Find lay, president of the Board of Health, Havana, 

 Cuba. Dr. Findlay early announced the carriage of yellow fever by 

 a certain species of mosquito (the same one, in fact, which was definitely 

 proved to he the carrier), but -his experiments were not conclusive, and 

 his conclusions were not accepted by the scientific and medical world 

 until nearly twenty years later, when the U. S. Army Commission 

 (Eeed, Carroll, Lazear and Agramonte) brought about the overwhelm- 

 ing proof which was generally satisfactory. Findlay's announcement, 

 however, was based on many years' study of the disease and of the 

 mosquito vector.
