The table shows the dry matter in the blood to be quite uniform 

 for the three lots, the corn-fed lot containing the lowest percent- 

 age. The total dry matter of the kidneys is highest with the 

 corn-fed pigs, the difference being due to the larger amoimt 

 of fat in the kidneys. The highest percentage of dry matter in 

 the kidneys to dressed carcass is for the pigs fed peas and com, 

 with those fed blood and corn coming second. 



112. Modifications of carcass. — That the bodies of the pigs 

 were affected by the feed given in these trials is made plain by 

 the colored engravings presented by Portier of France and the 

 •writer, i and by the half-tone reproductions from photographs by 

 Shelton^ and the writer. * These views show what Sanborn ansi^- 

 nally annoimced, viz., that there is more lean meat in proportion 

 to fat in the carcasses of protein -fed pigs than in the carcasses of 

 those getting corn meal.
