The lactometer is a little instrument used to estimate the specific gravity of milk.
Place lactometer in milk and note depth to which it sinks as indicated on stem.
For each 10° above 60° F. add 1 to the lactometer number, in order to make the necessary correction for temperature.
The specific gravity of milk is determined by means of the lactometer, an instrument which sinks to a definite point in pure milk.
He vowed and declared that the lactometer "no talkee true," and that no water whatever had been added to the milk, adding, that if I did not believe him he would bring a cow to the kitchen door and I could see it milked myself.
With a view to exposing fraud I purchased a lactometer and found the usual proportions of milk and water to be half and half.
Feeling sure that the lactometer must be at fault, I consulted my friend the doctor, who examined and found it quite correct.
A lactometer -- or instrument for testing the comparative richness of different species of milk -- is very convenient for this purpose; but any one can set the milk of each cow separately at first, and give it a thorough trial, when the difference will be found to be great.
