    has a longitudinal direction, and are most marked towards the lesser end of the stomach, and along the greater curvature; these folds are entirely obliterated when the organ becomes distended. STRUCTURE OF the MUCOUS MEMBRANE. When examined with a lens, the inner surface of the mucous membrane presents a peculiar honey-comb appearance, from being- covered with small shallow depressions or alveoli, of a polygonal or hexagonal form, which vary from one one-hundredth to one three- hundred and fiftieth of an inch in diameter, and are separated by slightly elevated ridges. In the bottom of the alveoli are seen the orifices of minute tubes, the gastric follicles, which are situated per- pendicularly side by side, in the entire substance of the mucous membrane; they are short and simple, tubular in character, toward the cardia; but at the pyloric end, they are longer, more thickly set convoluted, and terminate in dilated saccular extremities, or are subdivided into from two to six tubular branches. Watney has pointed out that these convoluted, or coiled tubes form the transition from the simple tubular follicles, to the convoluted glands of Brunner, which lie immediately below the pylorus. The gastric follicles are composed of a homogeneous base- ment membrane, lined upon its free surface by a layer of cells, which differ in their character in different parts of the stomach. Towards the pylorus these tubes are lined throughout by columnar epithelium; they are termed the mucous glands, and are supposed to secrete the gastric mucous. In other parts of the organ, the deep parts of each tube is filled with nuclei, and a mass of granules; above these are a mass of nucleated cells, the upper fourth of the tube be- ing lined by columnar epithelium: These are called the peptic glands, and are the supposed agents in the secretion of gastric juice. Simple follicles are found in greater or less number over the entire surface of the mucous membrane; they are most numerous near the pyloric end of the stomach, and are especially distinct in early life. The epithelium lining the mucous membrane of the stomach and its alveoli is of the columnar variety. VESSELS AND NERVES. The arteries supplying the stomach are, the coronaria ventriculi, the pyloric and right gastro-epiploic branches of the hepatic, the left
