results hardly hold tnic in ease of Kellner's trial with two 

 sheep, in which heet molasses composed 9.2 per cent of the dry 

 matter of the ration. Here one notes a depression of 14.4 grams 

 of organic matter per 100 grams of molasses. The two sheep 

 gave closely agreeing resnlts. 



In onr own case, when molasses composed some 20 per cent, of 

 a hay-molasses ration the depression was quite noticeable, aver- 

 aging in case of four single trials with four different sheep 10.14 

 grams of digestible dry matter and 7.37 grams of digestible 

 organic matter for each 100 grams of molasses fed. These latter 

 trials show a loss or depression equivalent to from 9.9 to 18.2 

 per cent, of the dry matter of the molasses fed ; or, otherwise 

 expressed, the molasses caused a loss of from 4.4 to 7.4 per cent, 

 in the digestibility of the hay. The feeding of 20 per cent, of 

 cane molasses did not cause as great a depression as did the 

 feeding of 9.2 per cent, of beet molasses (Kellner's results). It 

 is doubtful, however, if these varying results are due to the 

 different kinds of molasses. 



In experiments of this sort one is obliged to take into account 

 individuality, the effect of food upon different individuals, as 

 well as the condition of the animal at the time of the trial. 

 Positive conclusions cannot be drawn unless the evidence is 

 very pronounced. Why it is that two animals, both apparently 

 in good condition, should give contrary results it is difficult to 

 explain. Thus, in the above table note that molasses appeared 

 to have caused a depression of 21.09 grams dry matter with one 

 sheep and an increase of 3.36 grams with another; also, in 

 another case 100 gi'ams of molasses caused an increase of 5.21 

 grams and in another case a decrease of G.27 grams in the diges- 

 tibility of the hay. 



B. IIay^ Corn Meal and Molasses. 

 Two experiments were conducted in each ease with two sheep, 

 using 100 and 200 grams of molasses. Unfortunately, in each 

 experiment one of the sheep suffered from indigestion and did 

 not complete the trial.
