In examining the foregoing table, we notice the following points 
of interest : 
1. In most cases, the per cent. of fat in the milk is greatest 
during the first month of lactation. The Devons furnish an 
exception to this general statement, since the per cent. of fat was 
least in the first month of lactation. 
2. In the second month of lactation, the per cent. of fat drops 
considerably in most cases, the diminution being greatest in the 
richer milks. In the milks containing the smaller proportions of 
fat, as the Ayrshires, Holderness and Holsteins, the diminution 
of per cent. of fat continued until the sixth or seventh month of 
lactation, while with the Guernseys and Jerseys, the diminution 
continued through the third month. In the case of the Devons, 
the per cent. of fat increased "oradually from the first month 
throughout the entire period of lactation, with some fluctuations. 
3. The general tendency in regard to the influence of advancing 
lactation upon the per cent. of fat contained in the milk, is well 
shown by the following average of all the breeds:
