There- fore, one kernel weighs on an average gram. From the measurements recorded in the table the average volume of these kernels was calculated and found to be cubic milhmeters and the surface of such a grain square milli- meters. One hundred and fifty-seven grams of kafir were treated with sufficient water to loosen the bran and then separated with a dissecting needle into bran, germ, and endosperm. It was found that only enough water to wet the surface of the kernel was required and with two hours' standing in this condi- tion the bran could be removed easily. Regardless of the time of soaking, there was always some difficulty in getting the bran loose at the tip. The separation of the germ and endosperm at that point was also diflScult. For that reason there is probably a small amount of starch mixed with the germ, but special care was taken to keep tliis as small as possible. It was found that per cent, by weight, of the kafir kernel was bran; 10 per cent was germ; per cent was endosperm. This would amount to cubic millimeters of bran; cubic nuUimeters of germ; cubic millimetersof endosperm, if we assume that those three substances have practically the same specific gravity. On the same assumption the thickness of the bran would average millimeter. Surrounding the endosperm lies a very friable, more or less granular layer which seems to carry a large amount of coloring matter. Tliis.
