848 OCCUPATIONAL TUMORS AND ALLIED DISEASES choline prevent cirrhotic and carcinomatous liver lesions in rats, when added to their diet. Fieser maintained that it seems to be possible that cancer-producing hydrocarbons can be detoxified in the body by an interaction of disulfide com pounds. Maisin, Pourbaix, and Van de Voorde noted that sodium glucuronate administered in the food or by injection to mice painted with benzpyrene re duced the incidence of the resulting cancers, and a similar effect was obtained when vitamin Bx was fed to mice treated with the chemical carcinogen (Maisin, Pourbaix, and Camerman). The problem of occupational neoplasia and numerous and various disease conditions which lead to it form a part of the problem of physical and mental national health on which depends, in the final analysis, the vital strength of a nation, its cultural and economical efficiency, and its existence as a selfrespecting, independent, and valuable part in the community of nations. The care, preservation, and improvement of the health of the people as a whole represents one of the noblest and most important tasks of every genuine and honest government. Only that people is adequately equipped and prepared to face the unavoidable changes of fortune occurring in the life of every nation, and is able to withstand these perils with a firm confidence in its power, with an unshakable belief in its vital right of existence, and with an unquestioning conviction of its moral obligation of survival, that is sound in body, intellect, and soul. The fundamental requirements for a healthful living, not merely for a small, selected, and socially privileged group, but for the entirety of its citizens, must be safeguarded by suitable laws adequately enforced.
