A manual of human physiology, including histology and microscopical anatomy, with special reference to the requirements of practical medicine . ep or sub-serouslayer of looser areolartissue, containing manyelastic fibres. This layerof the pleura pulmonalisof some animals, as theguinea - pig, contains anet-work of non-stripedmuscular fibres (Klein).Over the lung it is alsocontinuous with the in-terlobular septa. Theinterlobular septa (, e) consist of bandsof fibrous tissue separat-ing adjoining lobules, andthey become continuous with the peri-bronchial connective-tissue entering thelung at its hilum. Thus the fibrous framework of the lung is continuous through-out the lung, just as in other organs. The connection of the sub-pleura! fibroustissue with the connective-tissue within the substance of the lung, has most im-portant pathological bearings. The interlobular septa contain lymphatics andblood-vessels. The endothelium covering the parietal layer is of the ordinarysquamous type, but on the pleura pulmonalis the cells are less flattened, morepolyhedral, and granular. They must necessarily vary in shape with changes in. Fig. 100.

The pleura contains many lymphatics, which com-municate by means of stomata with the pleural cavity.] [The Lymphatics of the lung are numerous and are arranged in severalsystems. The various air-cells are connected with each other by very delicateconnective-tissue, and according to J. Arnold in some parts this interstitial tissuepresents characters like those of adenoid tissue; so that the lung is traversed by asystem of juice-canals or Saft-canalchen.] [In the deep layer of the pleura, there
