less water in proportion to the dry matter of their fodder 

 than cattle. In round numbers, the normal amount of 

 water (in food and drink together) may be btated as 4 lbs. 

 per pound of |lry matter of the fodder for cattle, and half 

 that quantity for sixeep. 



In milk-giving animals an increased consumption of 

 water is less disadvantageous, and may indeed cause an 

 increased milk-production ; but in this case, also, it is un- 

 doubtedly advisable not to exceed a certain limit as to the 

 proportion of water in the fodder. 



The Efffeet of Stimulants on the protein consumption 

 seems to be inappreciable. The action on the nervous sys- 

 tem seems to be caused by so minute a metamorphosis of 

 albuminoid substance that it has no significance compared 

 with the total protein consumption in the body. It is, 

 however, anotlier and as yet undecided question whether 

 the increased nervous activity may not cause an increased 

 consumption of fat in the body, as does nmscular exer- 

 tion, e. g.

We see at once that even the largest rations of fat are 

 not able to stop or decrease the loss of flesh from the
