Owing to tlie very inferior condition of the hay the 
animals, two sheep of the Merino breed, with which the diges- 
tion experiment was carried out, refused for several days to 
eat a quantity sufficient for a reliable trial. It was but by 
slow degrees that they became accustomed to it, wherefore 
the preliminary period of feeding had to be continued, with 
the hay first given, for 12 days. As in researches on the 
digestibility of a feeding stuff much depends on as complete 
a consumption as possible of the food laid before the 
animals, the daily ration had to be cut down to 800 Grams 
per head. Even this small quantity was not totally con¬ 
sumed, but of the hay No. I more than 1 / i , of No. II more 
than y, was left uneaten and had to be collected and 
analyzed. The following figures show the averages of the 
8 days of the main period of the trial :
