Many special forms of dietetic treatment have been devised and extensively practised for the cure of pulmonary tuberculosis. The details of these "cures" are elsewhere described. The principal ones are the "Milk Cure" (p. 733), the "Whey Cure" (p. 735), the "Koumiss Cure" (p. 83), practised chiefly in the steppes of southeastern Russia, and the "Grape Cure" (p. 738), conducted at Me-ran, Montreux, and elsewhere in the months of September and October. Aside from climatic influences and the effects of good hygienic surroundings, their benefits are attributable only to the fact that the patient is encouraged to take a large quantity of easily digestible food and live constantly in the open air. Patients with chronic phthisis are notoriously sanguine as to the possibilities of their ultimate recovery, and it is also true that their mental state reacts to a greater degree upon their physical condition than in almost any other disease.

All manner of absurd foods, such as fish roes in Germany and snails in the south of France, have achieved fame with credulous persons as possessing specific virtues in the cure of phthisis. It should be as much the duty of the physician to protect them from the chagrin, disappointments, and expense of following dietetic illusions as to encourage them in every reasonable effort for improvement. Beyond the requirements of a good, nourishing, easily digestible diet, there is no specific food " cure " for tuberculosis, as there is no medicinal cure.
