Analytical Methods.—W ater was determined by drying two 
grams at 110° C. in a current of dried illuminating gas, ash b 
burning at a low temperature and deducting CO, and char, fat 
by extraction of the dry substance with dry sulphuric ether, 
crude-fiber substantially by tiie modified Weende method of 
Wattenberg.* Total nitrogen was determined by combustion 
with the mixture of slaked lime and sodium carbonate recom-

During the first period, each sheep received per day 1n tw? 
feeds 700 grams of hay from one of the 500 pound samples 
reviously mentioned, with water ad libitum twice per day: 
his amount of hay was eaten clean. The analyses above 8 ow 
the composition of the hay used for the preliminary feeding 
(No. 1) and the actual experiment (No. 2). As weighed out Ib
