The cut on the opposite page represents an apparatus, devised by the writer, that is being used in the college creamery to the great satisfaction of those who fortnightly test the composite samples. It is for measuring out the charges of acid for the Babcock test.
It may be described in a general way as consisting of two parts: First, a leaden receptacle connected with the acid carboy by a leaden siphon, and second, two glass burettes or measuring cylinders connected with each other and with a glass siphon which draws the acid from the leaden receptacle.
