150 Milk and Butter Tests at the Lincoln Show, 1007. 
Experiment No. 2. 
Weights oJ\various Milks. 
Having been asked in the Showyard “ which weighed the 
heavier — a gallon of Shorthorn or a gallon of Jersey milk?” I 
carried out the following experiment : — 
From the bulk of each lot of milk, which as already de- 
scribed, was collected in separate churns, I took about gallons 
by measure, the milk having in each case been thoroughly 
well mixed in order to obtain as accurate a sample as possible. 
I then filled a gallon measure to the brim and poured the 
milk into a pail, the tare of which had been previously 
ascertained. The pail and its contents were then weighed on 
scales, and the net weight of the milk noted. This experiment 
was carried out with both morning and evening milks. 
The following table gives the weights of morning and 
evening milks, and the average weights of the two.

It will be seen that a gallon of Shorthorn milk is heavier 
than a gallon of Jersey, and generally that the richer the milk 
the lighter it is in weight, the weights of the evening’s milk, 
with three exceptions, being lighter than the morning’s. 
This experiment would bear repetition, when gauged 
glasses or a hydrometer might be used to ensure more accuracy, 
for no matter what care is taken, with ordinary gallon measures 
it is impossible to guarantee absolute accuracy. 
Experiment No. 3. 
The Colouring of 3Iilk and Butter. 
The following simple experiment in colouring milk was 
carried out during three days of the Show with the object 
of demonstrating that the public are taken in by the colouring
