With smaller animals, having a shorter period of growth, the rela- 

 tions are even more striking. Thus, for the rabbit Bunge l reports 

 the following results. 



TABLE 1 20. PERCENTAGE COMPOSITION OF ASH 



It appears that while sodium and chlorin are the predominant 

 ingredients of the blood serum, these elements are present in milk in 

 relatively small proportions, while potassium, calcium and phos- 

 phorus predominate in the latter, the ash of milk closely resembling 

 that of the body of the same species. 



647. Average composition. Wing 2 cites the following 

 figures as showing approximately the average composition of 

 cow's milk 3 according to various authorities.
