PEPSIN DIGESTION AND ANIMAL DIGESTION. 
To show how close the digestion coefficients obtained by 
the Pepsin method accords to the actual digestion, made by 
the Germans, I give the following parallels for all similar 
substances tested.

Average for the above ....... 74.46 74.69 
The column from the German tables is the average of all 
their tests and not the result of single trials. It will be.seen 
that in many instances, the results obtained by the Pepsin 
method agree as closely to actual digestion as could be ex- 
pected had they been samples of the same fodder. 
AN ILLUSTRATION OF THE POSSIBLE AID FROM ARTIFICIAL 
DIGESTION. 
Chemical analyses shows us the potential, and not the 
nutritive value of a fodder. To make this more evident a 
few analyses are given by way of illustration.

We observe but little difference in the amount of al- 
buminoids between ox-eye daisies and the sample of hay, 
while in nitrogen-free extract and fat the daisies are far 
the richest, and from chemical analyses alone we would 
-consider, for feeding, the daisies as superior to the hay. 
The same is true of the two clover hays* and yet one was
