60 degrees F., multiply the difference between the temperature 
of the observed reading and 60 by the factor .0313 and add the 
product to the observed reading. 
Example: Beaumé at 120 degrees F. is 6.8; what is the 
reading at 60 degrees F.? 
Answer: 6.8 + (60 « .0313) = 8.68 degrees B. 
The corrected Beaumé reading is 8.68 degrees B. \When the 
temperature at which the reading is made is below 60 degrees 
I, multiply the difference between the temperature of the ob- 
served reading and 60 by the factor .0313 and subtract the prod- 
uct from the observed reading. 
Calculation of Specific Gravity from Beaumé Reading.—In 
order to record the density of the evaporated milk in terms of 
specific gravity. instead of Beaumé degrees, the following for- 
mula may be used: 
Specific gravity orate Ae B = Beaumé reading at 60 
145.5 — B 
degrees F. 
Example: Beaumé reading at 60 degrees F. is & degrees B. 
What is the specific gravity? 
Shas ie 145.5 aa 
Specific gravity = si els 1.0582 
Standardizing Evaporated Milk. 
is advisable to carry the condensing process slightly beyond the 
As previously suggested it 
concentration desired, so as to enable the operator to readily 
standardize it to the exact point desired by the addition of a 
small amount of distilled water 
As soon as condensation is completed the contents of the 
pan are drawn into a standardizing vat resting on scales. The 
evaporated milk is accurately weighed; the degree of concentra- 
tion is calculated by dividing the weight of the original fluid 
milk by the weight of the evaporated milk, and the amount of 
water necessary to bring the solids and fat to the exact stand- 
ard desired is calculated, and added to the evaporated milk. Ii 
it is desired to further check these results, or instead of weigh- 
ing the evaporated milk, it niay be tested for fat and solids, and 
the degree of concentration may be’ calculated by dividing the 
per cent of fat or of solids in the evaporated milk by the per 
cent of fat or of solids, respectively, in the fluid milk. For de-
