Making a Babcock Test.--The steps are the following: (1) Secure a fairly fresh sample of milk and thoroughly mix it. (2) Immediately insert the pipette or milk measure and suck until the milkhas goneabovethe mark on the pipette, then quickly place the forefinger over the top and allow the milk to run down to the mark by slightly relieving the pressure of the finger. The pipette now contains 17.6 cubic centimeters of milk. (3) Empty the milk in the bottle by permitting it to flow down the side of the neck of the bottle. (4) The acid measure contains, when filled to the proper mark, 17.5 cubic centimeters of acid. The measure should be filled with sulphuric acid with a specific gravity of 1.82 to 1.83. The acid should be emptied into the milk bottle in the same way as in the case of the milk. Permit it to run slowly down the side of the neck of the bottle. (5) Mix the acid with the milk by giving the bottle a rotary or turning motion. (6) Allow the mixture to stand a few minutes.

(9) Now add moderately hot water (above 180 F.) until the contents come to the neck of the bottle. (10) Whirl three minutes in the tester.
