This milk tester is a little instrument designed for testing the quantity of butter fat In any given sample of milk. The whole manipulation takes only a few minutes, and is so very simple that anyone can work it. A table supplied with the instrument shows at a glance, not only the percentage of butter fat, but also the proportion of same per gallon, the quantity of the milk required to produce each pound of butter, &c., so that there is no calculation ' at all required. Mr. Max. Pincus, who Is tho maker of the "Weigel Tester, shows tho remarkable accuracy of tho instrument. By request he tested a sample of the milk about to be separated, and the result as given to the Government dairy expert showed that the quantity of butter from the churning should be 59 lb. The actual quantity of butter as weighed (after adding 2 lb, of salt) was 61 lb., thus showing that the test agreed perfectly with the churning. In his report to the Minister of Agriculture, the dairy expert expresses himself as very pleased with the working of the Weigel test. The tester has recently been improved so as to measure exactly to tho smallest decimal. Mr. Pincus also shows samples of his butter preservative, called "Salva." In: THE LEADER SUPPLEMENT MAX PINCUS.
