In Table IV. are given the averages of the three samples of each cow's milk given morning and evening. The average fat for the three samples of the milk of cow A is 3.92; cow B, 3.26; and cow C, 3.24, and if these were all mixed together the average fat would be 3.45 for the morning milk. The average fat of the three samples taken from the cows A, B, and C in the afternoon is—A, 5.08; B, 3.08; and C, 3.54; and the average of the three milks is 3.85. In the same table are shown the first two samples of each cow's milk mixed together both morning and evening. By referring to Tables II. and III. under cow A it will be seen that the milk fat of the first and second samples is 2.30 and 3.67, and these added together are shown on Table IV. under cow A, and similarly with cow B and cow C night and morning. It will also be seen that the milk fat in the morning milk of cow A is 3.21; cow B, 2.49; and cow C, 2.15, and if these were mixed together the average fat would be 2.61. The average fat of two samples of milk taken from cow A in the afternoon is 4.50; cow B, 2.67; cow C, 2.12, and if mixed together the average fat is 3.08. It is interesting to note that if cow B was milked for six minutes in the morning, and the milk sold, the sample would be .51 deficient in fat, and the dairyman could honestly say that the milk was sold as it came from the cow. There is also a deficiency in the fat of the milk of cow C in the morning, and cows B and C in the afternoon.
