money by keeping inferior cows in his herd, a ad, by the 

 neglect of testing each cow's milk separately, cause the 

 good ones to support the inferior ones. Moreover, it is 

 by no means the handsomest cow or the largest milker 

 that produces the most butter. It is a curious fact, as 

 showing a physiological anomaly, that not only do cows 

 differ in this respect, but that the different glands of a 

 cow vary in the quality of the milk yielded. Thus one 

 quarter, or separate gland, of the udder will, in the same 

 cow, most always yield milk richer in fat than another. 

 The follow^ing figures, giyen in the paper of Dr. Sharp- 

 less above referred to, show this. The milk was drawn 

 from each teat separately, and separately examined. The 

 cow was a pure x^yrshire.

To afiSrm these unexpected results the milk of an- 

 other cow was examined and determined as follows : 



The coincidence in both cases as regards the left rear 

 teat, in which the fat product was nearly fifty per cent 

 less than that of the right forward teat, is very inter- 

 esting. While this is not a really practical matter, yet.
