These figures are supposed to represent hogs in average condition of fattening. For English hogs Lawes and Gilbert found the following relations:

Offal p a r t s Carcass... L o s s (evaporation, etc) 16.87 p e r cent. 82.57 p e r cent. 0.56 p e r cent.

This is for an average of 59 pigs having a weight of 212 pounds. (Harris on the Pig, p. 91.) Wolff gives the following on the average composition of well fed and fattened hogs (Armsby's Manual of Cattle Feeding):

Constituents. Well Fed. 7.3 16.8 74.5 46.4 8.0 16.5 1.9 1.7 Fat. 3.0 11.0 84.6

Eeferring to the live animal, he gives the following figures for the percentage composition:

Now all the figures I have given are those abroad, and with animals of European production. They are of value to American breeders and pork producers, but will scarcely be of the same interest as similar figures for American-grown pork. I have therefore taken some pains to secure such data, and by interviews and correspondence with some of the packers of Chicago, have been successful in obtaining the results of experiments in killing, that show nicely the relations of the parts in the American product also. I have received the following from Mr. John C. Hately, of Chicago:
