| Description | The authors announce that they have discovered the long-looked-for lymphatics of striated muscle, and describe them as radicles, valveless reservoirs, and waived efferent vessels. While describing their structure and relations, they point out that the reservoirs are found on one plane or side of a muscle; the valved efferents are found on the other side, as, for example, in the case of the diaphragm, transversalis abdominis, and triangularis sterni muscles. In connection with this, they have discovered a dense plexus of valved vessels on the anterior surface of the abdominal wall, corresponding to that on the pleural surface of the diaphragm. Upon the lymphatics of muscle they find the peculiar serous cells first described by [Carl] Ludwig and [Franz] Schweigger Seidel, whose views they fully confirm, in opposition to those expressed by [Louis-Antoine] Ranvier. They deny the existence of stomata in the Mammalia, but admit it in the case of frogs; and as the peritoneum of the latter is lined by crenated lymphatic endothelium, they admit its connection with the lymphatic system; but, on account of the absence of the latter endothelium as well as stomata from the serous cavities of mammals, they deny any connection between these and the lymphatics. While describing the structure of basement membrane, they discuss the facts adduced by Klein and [Georges Maurice] Debove as bearing on the question of absorption, and give their own views on this question. They hold that the lower surface of the diaphragm is an exuding one, and only an absorbent one when all the natural conditions are reversed.
