part of the grains will not interfere with the digestibility, 
as according to researches by Meissland Strohmer 1 ) 98.5°/ 0 
of the total dry matter and 88.6°/ 0 of the crude protein of 
the polished rice are digested by swine and according to 
K. Osawa men extract an equally high amount, viz. 97.5°/ 0 
of the dry matter and 80.1°/ o of the crude protein. 
There is, however, another thing that might sometimes 
prevent the feeder from using rice bran, it is the admixture 
of earthy materials which are very frequently resorted to 
for facilitating and accelerating the process of polishing. 
The resulting bran then contains about 20°/ 0 of ash, half the 
proportion of which is made up by the admixture. Besides 
these deteriorations direct adulterations consisting of ad¬ 
mixtures of sand, earth and other materials seem not to be 
rare; we have found as much as 60°/ o °f foreign substances 
in marketable rice bran. 
II. Soy Bean (Daizu). 
Although the soy beans are somewhat expensive owing 
to their principal utilization as human food (tofu, miso and 
shoyu), it may happen that small proportions of them are 
resorted to in the feeding of the live-stock, for the purpose 
of supplementing the protein of a ration otherwise to poor 
in that nutrient. 
The animals employed in the trials which were carried 
out by Mr. K. Ogasawara, were rams, No. I a Merino, No. 
II. a Southdown. The ration given per day and head con¬ 
sisted of 250 Grams of soy beans, 6 Grams ot' salt and 750
