weighed out, the yield of milk weiglied, and almost daily 

 analyses of it made. 



The results were in nearly all respects the same with 

 each animal, and hence only those obtained witli cow IS^o. 

 I. are given here. The following table '^ shows the average 

 amomit of milk given per day in the several periods (in- 

 cluding the preliminary feeding) under the influence of the 

 varying fodder:

In these experiments the natural decrease in the flow of 

 milk with advancing lactation is not taken into account, it 

 having been found, in previous experiments on the same 

 animal, to be very small. 



The increased yield of milk, imder the mfluence of the 

 more nitrogenous fodder of periods 2, 3, and 5, is very 

 marked, whether we consider the actual yield of milk or 

 reduce it to a uniform water-content. The increase in the 

 percentage of dry matter in the milk is equally evident. 



These results show plainly that a liberal supply of pro- 

 tein in the food favors an abundant production of milk ;
