Bunge has called attention to a relation which exists be- 

 tween the composition of a milk and the rapidity of growth 

 of the animal feeding on it. In the case of the young of the 

 dog, cat and sheep, for example, the rate of growth immedi- 

 ately after birth is very rapid and the milk of the mothers 

 correspondingly rich in proteins and calcium phosphate. The 

 young of the horse and ass are slow growers, that is a rela- 

 tively long period is required for them to double in weight. 

 These mothers' milks are low in proteins and salts, but rela- 

 tively high in sugar. In the human species these relations are 

 even more pronounced.
