Abstract
It was of importance in the evaluation of feedingstufrs to know its quantitative composition. A qualitative botanical indicated purity but a quantitative test was needed for the degree of purity. Natural feedstuffs always contained a certain amount of foreign material, which could be considered either as natural or chance contamination. The manufacturer had to ensure that commercial feedstuffs had a high degree of purity. Whenever there was consideration in the trade of standards for purity, it was necessary to be able to check these standards.
Ezendam worked out a method of measuring impurities both quantitatively and qualitatively. It was tested on some feedstuffs and thus led the way for microscopic study of feedingstuffs.
