The researches of Dr. Wiley, Chief of the Bureau of Chemistry in the United States Department of Agriculture, were important factors in hastening the enactment of the present pure food law. He analyzed the various food products and made public the deceptions practiced by unscrupulous manufacturers. He aroused attention throughout the country by pointing out the necessity of a campaign of education, in order, as stated in Volume V, Part II, that the housekeeper might be able to determine the purity of every article of food offered for sale. As an example of his methods, he organized a "poison squad" of government employees who restricted themselves to special diets, consisting of food preparations containing drugs commonly used as adulterants. In this way he actually demonstrated the effect of these substances upon the human system.] The Home Medical Library Volume II THE EYE AND EAR THE NOSE, THROAT AND LUNGS SKIN DISEASES TUMORS :: RHEUMATISM HEADACHE :: SEXUAL HYGIENE By KENELM WINSLOW, B.A.S., M.D. (Harv.) _Formerly Assistant Professor Comparative Therapeutics, Harvard University; Late Surgeon to the Newton Hospital; Fellow of the Massachusetts Medical Society, etc._ INSANITY By ALBERT WARREN FERRIS, A.M., M.D.
