[epith]elial surface of the gastric mucous membrane. These muscularprocesses are said to be concerned in emptying the glands. (In the gastric mucousmembrane of the cat, there is a clear homogeneous layer which is stained red bypicrocanniue, and placed immediately internal to the muscularis mncoste. It ispierced by the processes passing from the muscularis mueosse.) Masses of adenoid-tissue occur in the mucous membrane, especially near thepylorus, constituting lynqjh-follic/i <, which are comparable to the solitary glandsof the small intestine.
324 LYMPHATICS AND NERVES OF THE STOMACH. The Lymphatics are numerous, aud begin close under the epithelium bydilated extremities or loops (Fig. 136, d); they run vertically, and anastomose in themucosa between the gland-tubes, which they envelope in sinus-like spaces. They join large trunks in the mucosa; another plexus of large vessels exists in the sub-mucosa (Loven). (The Nerves.—A plexus of non-inedullated nerve-fibres and a few ganglion cells

exist in the muscular coat (Auerbachs), and another (Meissners) in the sub-mucosa.) The Blood-vessels are very numerous.
Small arterial branches, a, run in the sub-mucosa and ascend between the glands to form a longitudinal capillary net-work, c c, which forms a narrow net-work under the epithelium, and between its meshes the gland-ducts open (y). The veins gradually collect from this horizontal capillary net-work and run towards the large veins of the sub-mucosa, v. THE GASTRIC JUICE. 32) 163. The Gastric Juice. Properties — The gastric juice is a tolerably clear colourless fluid, with a strong acid reaction, sour taste, and peculiar characteristic odour; it rotates the plane of polarised light to the left (Hoppc-Seyler).
