    VIII. The Lymphatics. The Lymphatics: consist of two sets — the Superficial Lymphatics: Course, etc. — the Deep Lymphatics : Course, etc. — the Lymphatic Glands. a. The Lymphatic Vessels.—These are divided into two sets—the superficial, and deep. The former ramify beneath the pleura, throughout the entire extent of the superficies of the lung. The latter are found chiefly accompanying the ramifications of the blood-vessels and air-tubes throughout the interior of the organ. The two sets of vessels communicate at various points with each other. The superficial lymphatics are very large, larger than those of any other viscus; they are often dis- tinctly seen in a recent lung, which has undergone no process of preparation. The vessels are found running round the margins of the lobules, and from them branches arise which form a plexus, which is spread over the surface of the lobules. The meshes of the network forming the plexus assume a poly- gonal form for the most part. Tiie chief brandies which result from these plexuses pass towards the inner edge and root of the lung, and there they u.nite with the vessels of the deep plexus. The deep lymphatics are found accompanying for the most part the bronchial tubes and the branches of the pulmonary vessels; some are, however, found in the interlobular areolar tissue. They form branches of communication with the vessels of the superficial
