Payen* has given the following results of the analysis of wo- 

 man's milk from three several women :

The constituents of woman's milk in its normal state, accord-

According to Schubler most of the casein in woman's milk is 

 in the state of ricottin. But this remark does not quite accord 

 with the experiments of Meggenhoffer. 



According to the experiments of Schwarz, 1000 parts of wo- 

 man's milk leave an ash when burnt, weighing 4*407 : and com- 

 posed of, 



Phosphate of lime, 2-5 



Phosphate of magnesia, 0-5 



Phosphate of iron, . 0*007 



Phosphate of soda, . 0-4 



Chloride of potassium, 0-7
