Charts XCIX (rat 186, male) and C (rat 188, female) show the failure 

 of the rat to be maintained during periods i and 2 on diets mentioned below. 

 The perfect resumption of growth when the diet consisted of milk-paste 

 (period 3) illustrates that the "capacity to grow" normally is not visibly 

 impaired by previous large loss of body-weight. The food consisted of 



Constituents. 



Gliadin (from wheat) 



Edestin 



Starch 



Sugar 



Agar. 



Salt mixture I 



Lard

 seemed to be less efficient than the unsterilized faeces in period 4, or in other 

 similar experiments. The diet consisted of mixed food during period 1 ; for 

 periods 2, 3, and 4 it was as shown herewith.
