§114. The amount of this group, methoxyl, consumed was 
129.67 grams, that voided was 78.27 grams, digested 51.40 grams, 
percentage digested 39.64. 
AMID nitrogen in CORN EODDER. 
§115. The total amid nitrogen found was very small, that 
found in the fodder was 0.077 cent., equal to 0.481 per cent, pf 
proteids; that found in the orts was 0.045 cent., equal to 0.281 
per cent, of proteids. We found none in the feces. The total is 
very small, but it is evident that we have to attribute to it a coeffi¬ 
cient of digestion of 100.00.

THE CAEORIEIC VAEUE OE CORN EODDER AND ITS VARIOUS EXTRACTS. 
§117 The calorific value of the dry corn fodder was found 
to be 4,244 calories, and the total heat units fed amounted to 45,- 
533,876; the total value of the feces was 15,258,816 calories; the 
total heat value of the orts was 10,850,880 calories; the sheep there¬ 
fore appropriated 19,424,180 calories, or 56 per cent, of that con¬ 
sumed. 
§118. The sheep gained weight, ^>^2 pounds, during the five 
days that the test lasted. The gain was for the different sheep 2, i 
and ^ pounds, respectively. The number of heat units appropri¬ 
ated by the sheep is less than in the case of the native hay, 22,255,- 
418 calories, while the gain in weight is the same; the coefficient 
of digestion, however, is higher, it being in the case of the native 
hay 48.34 per cent., and in the corn fodder 56 per cent. In timothy 
hay it was 47.83 per cent., and the heat units appropriated by the 
sheep were 17,406,363. One of the sheep gained and two lost, re¬ 
sulting in a net loss of one pound for the three sheep:
