Three methods for the determination of milk fat, namely, Gerber's, TeSa's and Japanese detergent method, were compared for accuracy, safety, and rapidity. TeSa method needs neither corrosive acid nor centrifuge machine, and if its reagents were fresh, it gives good results even in field experiment, but their patented reagents cannot be easily obtained in Japan. The Japanese detergent method using Tween 80 is the same as Gerber's in accuracy and rapidity, but because of the detergent action, it is necessary to employ a new model of butyrometer, and if not, the rubber stopper comes off easily. The Japanese method with this special butyrometer seems to be the most convenient in all points.
