[Jan. 



a depression in the hay of 7.2 (7.02) grams of dry matter and 

 4.1 grams of organic matter. The depression was equivalent to 

 9.9 per cent, of the dry matter of the molasses fed. The total 

 molasses likewise cansed a loss of 4.4 per cent, in the digesti- 

 bility of the dry matter of the hay.

 hay and molasses are brought together for comparison. The 

 results of one experiment by Kellner are also stated.

The nutritive ratio of the different lots of hay varied from 

 1 : 7.5 to 1:0.9; the addition of different amounts of molasses 

 naturally widened the ratio, variations being noted of from 

 1: 8.6 to 1 : 11.2. So far as one is able to judge, the different 

 ratios were without effect on depression. Our own experiments 

 indicate that when cane molasses constituted from 10 to 13 per 

 cent, of the dry matter of the total ration it was without pro- 

 nounced effect on the digestibility of the hay. In case of one 

 trial with one sheep the depression was very marked, but in the 

 other five single trials with different sheep the influence was 

 slight, or one trial was contradictory of the other. The same
