A cap of filter paper is then placed over one end of the coil and secured by the ends of the string. The coil is then suspended by some simple means, the capped end being downward, and 5 c. c. of the milk to be tested, run on to the upper part from a pipette. The milk is rapidly absorbed by the paper and none filters through the cap. It is then dried in a water oven for an hour or two. Sour milk must be weighed and thinned with a few drops of ammonium hydroxid before absorption by the paper. Heavy filter paper of good quality, which yields to ether only a milligram or less, may also be employed, as suggested by Thomson. One end of the strip is fastened to some convenient support, and the other be- tween the fingers. The paper being kept horizontal, 5 of the milk are taken in a pipette, and distributed evenly over it, the end of the pipette being wiped on a part left dry for the purpose. It is dried by passing to.
