Variations of Fat. The author has found the amount of 

 fat in buttermilk to vary from 0-15 per cent, to 5-60 per cent. ; 

 the last percentage is very unusual, and it is rare to find even 

 as much as 2-0 per cent., percentages higher than this denoting 

 that the churning has been carried out inefficiently.
