Not illustrated. 1882 Excerpt: ...proportions than any other part of the grain. If any means could be employed by which the grain could be divested of all its coats excepting this last, and this last coat could be treated in such a way as to separate the nitrogenous sacks from the framework holding them, and then have the sacks form a part of the flour, we would probably have the finest and purest flour possible. The process of scientific milling has made such great advance during the past twenty-five years, who can say but ere the next twenty-five years pass, we shall have these microscopical sacks of nutrition separated out from the woody part of the grain. The gluten, or nitrogenous substances, exist in very minute particles, about, i6oo of a millimeter (1-15000 of an inch) in diameter. They are insoluble in water, alcohol and glycerine, and are not affected by iodine or potassa. Ammonio-nitrate of silver turns them a dull yellow, while a solution of carmine turns them a bright yellow. Nitrogen is found only in cell-contents, and is never found in cell-walls. 8. Inside of the layer of albumen is found only one structure until we reach the embryo, at the base of the grain. It is composed of large, thin-walled hexagonal cells, loaded with starch, see Fig. 2. To see these cells plainly under the microscope a very thin section must be cut from the central part of the grain with a razor, or a sharp knife, and then washed off carefully with a camels-hair brush, so as to remove the grains of starch, when we find a delicate white structure resembling a honey-comb in all except color. At the center of the grain the cells are the largest, and are quite uniform in shape and size, measuring nearly 1-10 of a millimeter (1-250 of an inch) in diameter. At the surface of the albumen the cells are quite ...
