In the winter of 1913 the FrenchSenate reicilved that the protective treatment should bemade eompulsoi-y throughout the French army; and, inspecial circumstances, among the reservists.

But thatis hardly a disease likely to trouble the soldiers. Thetubercle bacillus is another germ conveyed by flies. Theyare particularly foud of feeding on saliva, and Lord, Haj-ward, and have obtained virulent bacillifrom the intestines and dejecta of flies which had been fedon tubes containing tuberculous sputum. These experi-ments have been amply confirmed by other workers. Anyone who has ever been in Egypt will remember the terrible sight of the flies days after first com-ing in contact withthe germs.
