To quickly assess the difficulty of the text, read a short excerpt:
Twelve 18 gram samples of cream were very care- fully weighed upon each type of scale, extreme care being taken in placing the cream in the Babcock bottles not to add an excess. If a few drops of cream in excess were accidentally poured into the bottle, the same were removed so as to bring the scale back as near as possible to a perfect balance. The samples were then reweighed upon the Becker office balance and the variations in weight recorded. The results obtained again show that the more sen...sitive the scale, the more accurate the weighings recorded and the less the variation of duplicate samples. By studying the variation of the duplicate weights in grams, it will be observed that the greatest variations were obtained upon the twelve bottle Fairbanks cream test scale No. 950, the four bottle Fairbanks cream test scale No. 949 and the twelve bottle torsion balance No. 30'05. In these experiments the twelve bottle Troemner balance with hanging pans. No. 6612, is the only type of twelve bottle cream test scale that gave reasonably accurate results.
