Text Appearing Before Image:
don of the diaphragm is provided with stomata, or open communi-cations between the peritoneal cavity and the lymphatics in the sub-stance of the tendon, v. Eecklinghausen found that milk put uponthe peritoneal surface of the central tendon showed little eddies causedby the milk-globules passing through the stomata and entering thelymphatics. The central tendon consists of two layers of fibrous tissuearranged in different directions. When the diaphragm moves duringrespiration, these layers are alternately pressed together and pulledapart. Thus the spaces are alternately dilated and contracted, lymphbeing drawn into the lymphatics (Fig. 164, Ji) through the stomata). 416 MOVEMENT OP THE LYMPH. (Lttdwigs Experiment. —Tie a respiration cannula in the trachea of a deadrabbit; cut across the body of the animal immediately below the diaphragm;remove the viscera, and ligature the vessels passing between the thorax andabdomen; tie the thorax to a ring, and hang it up with the head downwards;

Section of central tendon of diaphragm—The injected lymph spaces, h and h, areblack. At/the walls of the space are collapsed (Brunton, after Ludwig andSchweigger-Seidel). pour a solution of Berlin blue upon the peritoneal surface of the diaphragm;connect the respiration cannula either with a pair of bellows or an apparatus forartificial respiration, and imitate the respiratory movements. After a few minutes,the lymphatics are filled with a blue injection showing a beautiful plexus.) (The same kind of pumping mechanism exists over the costal pleura(p. 224).) (The fascia covering the muscles is another similar mechanism. Thefascia consists of two layers of fibrous tissue, with interveninglymphatics (Fig. 165). When a muscle contracts, lymph is forced out
