MILK ANALYSIS 



A good plan is to use a 5 c.c. pipet and to wash out that 

 which adheres to the glass with a little water. The specific 

 gravity of the milk being known, the amount taken can be 

 calculated. The milk should be as near 15.5 as possible. 



Specific Gravity. Air-bubbles are held rather tenaciously 

 by milk, and care must be taken in mixing, preparatory to 

 taking the specific gravity, to avoid as far as possible the 

 inclosure of the air, and to allow sufficient time for the escape of 

 any bubbles that may be present. The specific gravity of milk 



Find the temperature of the milk in one of the horizontal lines and the specific 

 gravity in the first vertical column. In the same line with this and the tempera- 

 ture the corrected specific gravity is given.
