Answer : 



Specific gravity of milk = 1.035 



35 

 Total solidS' — j 1- 1.2 X 2 = 11.15 per cent. 



Solids not fat -^ 1- -2 X 2 = 9.15 per cent. 



Specific gravity of milk solids 

 11.15 



11.15 — 100 X 1.035 — 100.-= 1.446 



1.035 



Uxample of milk from zvhich cream ivas removed and to which 

 tinier was added. — Quevenne lactometer reading at 60 degrees F. 

 32. fat 2 per cent. 



Specific gravity of milk = 1.032 



Total solids -^ \- 1.2 X 2 =10.4 per cent. 



3? 

 Solids not fat —j-- + .2 X 2 = 8.4 per cent. 



Specific gravity of milk solids 

 10.4 



10.4 — 100 X 1.032 — 100 = 1.425 per cent.
