LONDON  (From Our Regular Correspondent)Aug. 17, 1935.

A Veterinary Centenarian and Discoverer  Dr. Griffith Evans of Bangor, North Wales, attained his hundredth birthday, August 7. While in the army veterinary corps in India he discovered the trypanosome of surra, a disease of horses, camels and cattle. In 1885 this protozoon was named Trypanosoma Evansi. He thus laid the foundation of protozoon pathology, in which the next discoverer was Bruce, who in 1894 found that tsetse fly disease of animals was due to another trypanosome (Trypanosoma Brucei). In 1903 he and Nabarro found that the tsetse fly also was the carrier of trypanosomiasis. In a letter to the Times, Dr. Ivor J. Davies of Cardiff recalls a visit of Osler to that town. He asked, "Where does Griffith Evans live?" A reply not having been forthcoming, he said: "What! Don't you know the man who first saw a pathogenic trypanosome?"
