5 The food chosen was corn and linseed meal. In these foods the nu tritive ratios usually range about 1:8 and 1:2.5 respectively. But on account of the poor quality of the corn of 1883 and the rather inferior quality of the linseed meal procured, these ratios were not realized, and what we had proved to be 1:8.94 and 1:4.7 respectively. This is shown in the following statement of results of analysis of these products: ANALYSIS OF INDIAN CORN AND LINSEED MEAL SWINE. FED TO EXPERIMENTAL Corn.

These furnished corresponding nutritive ratios as follows: 1:6.82, 1:7.56, 1:8.23, 1:8.94. In view of the fact that the ratios were so wide it would appear that lots 2 and 3 had almost practically the same ratio. The arrangement of the animals, the mixtures fed, the periods of feeding and the increase of weight during the several periods of the experiment are shown in the following table: EECORD OF FEEDING AND GAIN IN LIVE SWINE. or]RATION.
