THE STOMACH.
The stomach is the most important organ of digestion. It has three coats; that which has most to do with digestion is the mucous coat, which lines it; this coat is supposed to furnish, by its glands, what is called gastric juice, which is the principal agent of digestion. The stomach is abundantly supplied with nerves, and holds a very powerful sway over the whole nervous system—so that, when the stomach is under the influence of disease, either acute or chronic, the whole system is immediately in a state of suffering. To secure, then, a healthy organization, the stomach must be kept in health.
