superficial layers of the grains mixed with some broken 
pieces or powder of whole grains. The quantity of bran 
obtained from 100 p. of the raw seeds is not great, amounting 
only to 7-8 percent, as it is shown by the following trials 
made by students of our college with the help of the com¬ 
mon wooden hammers and mortars ; there resulted from 
100 p. of raw rice : —

Numerous analyses 
made in Europe 
have already 
proved that the rice bran 
is a very nutritious fodder rich 
in albuminoids and fat and particularly suited for the feed- 
iug of milk cows and for fattening. Researches on the 
digestibility have, however, not yet been made. — In Japan 
these brans, like so many other materials of a high feeding 
value, are still widely applied directly as manure, instead 
of utilizing them first as food for domestic animals and 
thereby increasing the manurial effect. 
The digestibility of a specimen of rice bran was de¬ 
termined in 1884 by Mr. S. Kakizaki, who supplied rams of 
the merino breed per day and head with a ration of 750 
Grams of common hay, 250 Grams of bran and 6 Grams of 
salt, which was completely consumed. The hay given had 
been examined in a preceding experiment (described p. 9) 
as to its composition and digestibility. 
The quantity of fæces ejected, water drunk and the 
live-weights, as observed in the main period, were as 
follows :—
