Chemical and physical analysis of milk, condensed milk, and infants' milk-foods, with special regard to hygiene and sanitary milk inspection : a laboratory guide, developed from practical experience, intented for chemists, physicians, sanitarians, students, etc. Milk; Infants. 9 Physical Analysis of Milk. COLOR. Normal: Milk in its normal state is opaque white to yellow. During winter it is more white, while in summer the color is more or less yellow, produced by the richness of the food in chloro- phyll. Plants containing certain coloring substances, may impart certain hues to the color of milk. Pecuharities of color may, how- ever, be produced by other causes. Med: Red milk is mainly caused by a general diseased condition of the cow, and has been found in cases of anthrax, as an accom- panying symptom of red murrain, and after the use of acrid and resinous remedies. Such milk contains many blood corpuscles and gives on standing, a sediment. Milk appears sometimes irregularly colored, the color appearing in streaks or attached to coagulated rnasses, which collect rapidly at the bottom of the vessels. The occurrence of such milk is fre- quently confined to certain parts of the udder, ana is then caused by congestion, inflammation, and mechanical injuries inflicted upon the udder. Detection: Blood corpuscles are easily detected by the micro- scope. They are recognized by their yellowish color and their shape. They present themselves as small disks, slightly indented in the centre. This can best be seen on single corpuscles. They are frequently united, forming bodies similar to rolls of specie.
