Table VI.— Summaiy of Mean Percentages of Niteogen in Ten Animals. 
1st. In Eresli Carcass.— 2nd. In Eresh Offal (equal Sura of Parts excluding Contents of Stomachs and 
Intestines). — 3rd. In Entire Animal (Fasted Live- weight, including therefore Contents of Stomachs and 
Intestines). 
[The mean percentage of Nitrogen from Total Parts in the Entire Animal is given— 1st, by addition of the 
amounts in the separate items — 2nd, by direct determination on the mixture of aU crude dry parts (except wool, 
the amount in wool being added by calculation)— 3rd, by calculation, deducting fat and mineral matter from 
total dry, and dividing by 6‘3— an average per cent, of nitrogen, of 15’873, in the nitrogenous substance.]

These Tables of the percentages of actual nitrogen (V. and VI.), will enable us con- 
veniently to compare the relative nitrogenous percentage of one animal, or its several 
parts, with that of another, and also, the duplicate results obtained by different methods 
of experimentation, or calculation, as the case may be. The amounts of nitrogenous 
compounds which the amounts of the nitrogen itself are supposed to represent, will be 
better considered further on, when we shall have before us, side by side, and at one view, 
the percentages in the ten animals or their collective parts, of the several classes of con- 
stituents of which the whole is made up, namely — mineral matter, dry nitrogenous com- 
pound, fatty matter, and the total dry substance and the complementary water. 
* In these cases, two sets of determinations were made, at different times.
