The absorption of fluids by the minute radicles of the veins of the stomach is so rapid that in cases of poisoning by hydrocyanic acid, death occurs in a few seconds. There is no doubt that the gastric juice which is poured out in such large quantities during the process of digestion in the stomach is absorbed together with the albumose, the dissolved salts, and the sugar derived from the food. In this way the system is relieved from the excessive drain which would be thrown upon it, if the whole of the gastric juice required for the digestion of a meal had to be manufactured and thrown out anew each time. The absorption of the gastric juice secreted in the process of absorption, in conjunction with the soluble albumoses or peptones, is one of the most important things to remember in the dietetic treatment of dyspepsia; for, if we could succeed, by means of the rapid absorption of fluids by the veins of the stomach, in providing the peptic glands with the material out of which to manufacture pepsine, the digestive process could be immediately aided in cases of atonic dyspepsia.
