(Adult Pelophilus survived 3-4 years.) In amphibia, Swingle ('18) starved yearling tadpoles of Rana catesbiana for 5 months with marked skrinkage of the body (weight undetermined). Fig. 33.—From a photograph of a female dog after 60 days of complete total inanition with loss of 49 per cent in body weight. (Falck '75.) On incomplete inanition (diet merely restricted in amount), Aron ('n) discovered that growing puppies can be held at maintenance (constant body weight) for several months; but ultimately the amount of food has to be increased so as to permit some increase in body weight, otherwise death from inanition results. Jackson ('15a) similarly observed that albino rats held at maintenance by underfeeding live only about 2 months unless a slight increase in body weight is permitted, and Stewart ('18, '19) found that newborn albino rats can be held at maintenance by underfeeding for only 2-3 weeks. Thus the period of survival in growing animals on maintenance diet varies directly with the age. A diet below the maintenance requirement will pro- duce death more rapidly, with actual loss of body weight, while a diet above the
