of digestibility. 
e. g. 
amount digested out of 100 parts of each constituent, are

In 1883 another sort of hay of the same origin was 
examined in regard to its composition and digestibility by 
Mr. K. Makino. The animals used were Merino rams. 
They were supplied per day and head with 1 Kilogram of 
hay and 7 Grams of common salt, which were completely 
consumed. The quantity of water drunk, the live-weight, 
and the excreta ejected were during the main period as
