All growth ceased during the edestin feeding (period 2), in contrast with other experiences where protein- free milk was present in the dietary. Chart LXXI (rat 218, female) shows inadequate growth on a diet of edestin+milk-paste (period 1) followed by growth during period 2, chart lxxi. in which the food contained pro- tein-free milk and edestin as its sole protein. In growing to several times its original weight the animal must have synthesized its purine- and phosphorus-containing com- plexes from purine-free food. The influence of size on food require- ment is shown by the food-intake curve. The diet consisted of—. Period I.
