Using formula 3 : 

 iL + .2f + .14 = S.N.F. 

 32.5 -T- 4 = 8.12 

 .2 X 4.2 = .84 

 8.12 + .84 + .14 = 9.10 S. N. F. 

 9.10 + 4.2 = 13.30 T. S. 



By modifying Babcock's third formula the total solids may 

 be obtained directly. It is as follows : 



iL + 1.2 f -f .14 = T. S. 



Using the above lactometer and fat readings as an illustra- 

 tion, the formula would give the following results : 



32.5 v4 = 8.12 



1.2 X 4.2 = 5.04 



8.12 + 5.04 + .14 = 13.30% T. S.
