If) RESEARCHES ON THE COMPOSITION 
ia this vegetable nutrient, so far as the composition of 
the dry matter is concerned, whereas the proportion of 
phosphoric acid and potash is rather inconsiderable in all 
three kinds of manure. The sea cucumbers and star fishes 
are, moreover, distinguished by a large content (30—40°/„) 
of calcium carbonate, which, as it is intimately mixed with 
some organic matter, will readily come into effect in the 
soil. 
V. Rice Brans, 
Tor comsumption in the country itself the rice is 
cleaned (whitened) invariably by means of wooden mortars 
and hammers which yield a finer product and less broken 
grains than the mills generally applied in foreign countries 
or for the rice destined for exportation from Japan. Fre¬ 
quently a slight proportion of sandy materials is mixed with 
the grain in order to facilitate the process of cleaning. 
For the purpose of getting a reliable average result for 
the composition of the bran, 100 grms. of each of 7 speci¬ 
mens from the following places, resp. provinces : Ise, Mi to, 
Etchiu, Mino, Nambu, Tokyo and Bushin, were mixed 
and analyzed by Mr. T. Yoshii. All the 7 kinds of bran 
were purchased on condition that no sandy materials had 
been used in whitening. The composition of the mixture 
was as follows :—
