APPETITE IN RELATION TO BODILY NEED AS REVEALED BY THE SELF-SELECTION METHOD OF FEEDINGBodily Need and Survival A bodily need is here denned operationally in terms of deprivation and survival of the individual. If a rat or man is deprived of oxygen, he can survive a few minutes. If deprived of water, in the presence of all other nutritive substances, he can survive a few days.Richter and collaborators (56) determined the survival time of rats maintained upon air and water plus one other nutritive element. With separate groups of animals they tested singly each of five fats, five carbohydrates, and six proteins. In terms of the length of survival the food elements within each group were ranked in an order of their beneficial effect in sustaining life. Among the fats (olive oil, lard, wheat germ oil, cod-liver oil, peanut oil, perilla oil), life was maintained longest upon olive oil. Of the carbohydrates (dextrose, sucrose, starch levulose, lactose, galactose), lactose gave the longest survival. Among the proteins (casein, desiccated blood fibrin, egg albumin, lactalbumin, hemo-
