DEX SI METRIC METHOD.

The author has found that if the specific gravity of the filtered 

 milk less 1 be divided by 0-004, and the difference between the 

 specific gravities of the milk before and after filtration be divided 

 by 0-0008, the figures so obtained represent very fairly the solids 

 not fat and fat respectively. The following figures (Table XXVIII. ) 

 will show the agreement that may be expected : 



TABLE XXVIII. ESTIMATION OF MILK SOLIDS BY 

 DEXSIMETRIC METHOD. 



Great accuracy cannot be expected from this method, but it 

 has the advantage of not requiring chemical apparatus. Deter- 

 minations can be made with a small delicate lactometer, and an 

 idea of the quality of the milk obtained in a short time.
