162 MILK [x 



(5) For calculating the percentage of total solids 

 from the fat and specific gravity : 



The following is a formula which has been devised 

 by Hehner and Eichmond, and which has been largely 

 used in England : 



F=-859T- -2186G 



This formula suffices for normal milk, but for 

 skim milk it has been found necessary to modify it 

 as follows : 



F=-859T- SlSeG-'OSf --2 



The above correction has only to be applied when 

 the specific gravity (G) divided by total solids 

 exceeds 2*5. 



H. Droop Eichmond has quite recently 1 devised 

 a formula for calculation of total solids from the 

 specific gravity and fat. It is as follows : 



T = ? + ? F + -14 



Chemical Analysis of Milk. With regard to the 

 chemical analysis of milk, the subject is one which 

 does not admit of being discussed with any fulness 

 in a work like the present. It may suffice to mention
