per cent. of fat and 83. viscosity, or a coefficient of Viscos- 
ity for the fat of 16.7. Substituting this last coefficient in 
the average analysis for the skimmilks, gives a coefficient 
of viscosity for the solids not fat of 20.36. 
From these coefficients the following formule are de- 
rived : 
x=per cent. of fat. 
wae BOLLS not fat, 
V =total viscosity of milk. 
a=coefficient of viscosity for total solids. 

b= 66 (74 G6 66 fat. 
c= A A a “solids not fat. 
Total solids = 
then, 
BY, 
x+y = a 
and, 
bx+cy=V. 
Solving these equations gives:

es =a V,and y an V 
Substituting the values for a, b and c, found in the whole 
milk gives x=.0195V. y=.0331V. 
The total solids, fat and solids not fat, in each of the 
whole milks mentioned in the last table, calculated by 
these formula are given below:
