And this last table brings out the relation with great clearness. 
We may also infer from the uniformity between the amounts of water 
drank during the five-day subdivisions of each period, that the amount 
drank was strongly influenced by the character of the food, more 
under the bran feeding than with the hay alone, etc., in the following 
order: Hay and bran; hay, corn meal and bran; hay, linseed meal 
and pumpkin; hay and corn meal; hay. 
During these feeding trials, we have the following nutritive ratio, or 
the relation between the digestible albuminoids and the digestible 
carbohydrates, plus the digestible fat, multiplied by 2.5, the figures 
under which the calculations are made, being those gained by arti- 
ficial digestion of the foods used in this trial, for the albuminoid, and 
those given by Armsby in his Manual of Cattle Feeding for the carbo- 
hydrates and fat.
