stoppered bottles and taken to the laboratory every twenty-four 

 hours. The daily sample was poured upon a newspaper, well 

 mixed and an aliquot part (usually Vio) weighed into a crystal- 

 lization dish and dried at 00° C. After this drying was com- 

 pleted the samples were allowed to stand at ordinary temperature 

 for a number of days, and were reweighed, mixed, ground, placed 

 in glass-stoppered bottles and eventually analyzed. Nitrogen 

 was determined in the dry sample but not in the fresh fseces, as 

 is frequently done at the present time. The entire period lasted 

 fourteen days, seven of which were preliminary, the faeces being 

 collected during the last seven. The sheep were kept in roomy 

 stalls during the first three days, and then harnessed and placed 

 in the digestion stalls for the last eleven days of the trial. 



The results of the different experiments are first presented, 

 together with a discussion of the same. The full data follows 

 the discussion.

From the above coefficients it would appear that Sheep II. 

 digested only 69 per cent, of the total dry matter of the molasses, 

 while Sheep III. digested the entire amount fed. It can, how- 

 ever, be safely assumed that molasses, being quite soluble in 

 water, is easily digested and entirely resorbed in the digestion 

 tract. Only minute traces of reducing substances have been 

 recognized in the fteces.
