Tlie salt, therefore, both stimulates the glands to activity and fur- nishes the material upon which they may act. In this way it is a very powerful agent to increase the appetite. When the hydrochloric acid has fulfilled its duties in the stomach and passes into the intestine, it combines with a part of the soda of the bile to form chloride of sodium again, and this very reaction stimulates the secretion of bile. The presence of chloride of sodium in the fluids of the intestine regulates the diffusion of substances through the blood-vessels of the intestinal villi into the blood; and when the salt has passed into the blood, it again regulates the diffusion of material from the blood to the tissues, and from the serum of the blood to the blood corpuscles. The albuminous substances that must be absorbed from the intestine and finally fixed in the tissues, find great difficulty in passing through the walls of blood-vessels and of cells composed of material anal- ogous to their own. These substances are called col- loid, or jelly-like, on account of this difiiculty of transfusion. On the other hand, substances that crystal- lize, mineral salts, and especially chloride of sodium, dif- fuse with great facility, and when they combine with albumen, they carry the latter along with them, first into the cells to build them up—then out of the cells, when](https://iiif.wellcomecollection.org/image/b21018911_0032.jp2/full/800%2C/0/default.jpg)
