It will be observed that although a wide variation 

 exists in the fat content of the milk of individual 

 animals, ranging from 2.6 to 8.3 per cent, in the 

 month of December, the composition of the entire 

 daily product is remarkably uniform — 4 per cent, of 

 fat could have been safely guaranteed throughout 

 the year. The lowest, 4 per cent., is found in the 

 month of March, 1897, and the highest, 4.4 per cent., 

 in August and October, 1896, or a range of .4 per 

 cent, between highest and lowest, a difference so 

 slight from month to month as not to materially
