ANALYSIS OF THE ASH OL MlLK. 



The milk from which the ash was obtained for these analyses 

 was not taken at random, hut represents five consecutive rnilkings 

 from each cow. 50 cubic centimeters being taken from each lot of 

 miik -at each milking. The skimmed milk represents the same 

 lots a » the whole milk. 



For the benefit of those who are not familiar with chemical 

 methods, it should be stated that the potassium, sodium, iron. 

 etc.. found in the ash were calculated as oxides. It is probable. 

 however, that all the chlorine present is combined with these ele. 

 ments. and that the weight of the ash as calculated is too gTeat 

 bv the amount of oxygen which would be replaced by the chlorine 

 found. About 71 parts by weight of chlorine would replace 16 

 paits of oxygen. This correction is applied in all these tables.
