the body,
taken as a whole, should be considered. On an average, then, it will be
found that a fat fully-grown animal will contain 49 per cent. of water,
33 per cent. of dry fat, 13 per cent. of dry nitrogenous matter--muscles
separated from fat, hide, &c.--and 3 per cent. of mineral matter. In a
lean animal the average proportions of the various constituents will be
54 per cent. of water, 25-1/2 per cent. dry fat, 17 per cent. of dry
nitrogenous substances, and 3-1/2 per cent. of mineral matter. In the
following table these proportions are set forth.

SUMMARY OF THE COMPOSITION OF THE TEN ANIMALS--SHOWING THE
PER-CENTAGES OF MINERAL MATTER, DRY NITROGENOUS COMPOUNDS,
FAT, TOTAL DRY SUBSTANCE, AND WATER.

1st. In Fresh Carcass. 2nd. In Fresh Offal (equal Sum of Parts,
excluding Contents of Stomachs and Intestines). 3rd. In Entire
Animal (Fasted Live-weight, including therefore the weight of
Contents of Stomachs and Intestines).
