Observations among the animal kingdom show that the carnivora rarely have tuberculosis, while the vegetable feeders are particularly prone to this form of disease. Carnivora, while fed upon an animal diet, cannot be successfully innoculated with tubercular matter ; confined and fed upon an opposite class of food products and the experiments rapidly become successful.

Tuberculosis in the human subject is most frequently found in starch and sugar-fed subjects and in those who are compelled to live in close quarters.

The only line of treatment that has yielded any satisfactory results has been the sending of such cases to the wild mountain regions where the diet of necessity is largely of the animal class, such as game and fish. With this out- of-door life, an almost exclusive use of an animal diet, and a moderate amount of alcohol and cod-liver oil to supply what CHO element the system absolutely demands, has resulted in the positive cure of a fair percentage of genuine tubercular subjects.
