& Obtained from previous digestion experiments similar to the one under discussion, in which a part 
of the same lot of hay and gluten feed was used. 
Table IX shows that the two digestion trials for nitrogen-free extract 
agree very closely. It is to be noted further that this extrafct matter 
constituted about 85 per cent of the total dry matter of the vegetable- 
ivory meal and that it had a digestibility of 94 per cent. In the case of 
the fat and ash the results are uncertain, but this is not surprising because 
so very little of these two ingredients is present. The digestibility of the 
fiber is not very satisfactory, and the same may be said of the protein. 
The percentages of these two ingredients, however, in the vegetable- 
ivory meal are relatively small.
