    reaching the capsules. On the surface you can see distribu- ted as many as twenty. (Kolliker,) and of these, some after coining along the cortical surface send down twigs which ramify into the dissepiments made by stroma of connective tissue, thus surrounding the cortical cylinders with a capil- lary coat; the others run immediately at right angles to the medullary portion, where, forming minute ramifications, they return again to the cortical portion according to Nagel and Frey, and these, anastomosing with those which ramify in the cortical portion, cause the medullary substance to be less vascular than the cortical. Veins.—Those vessels are supposed to take origin in the central portion of the medullary substance, coursing to the surface, uniting in one larger vein, running in the fossa at the base of the capsule, to empty, on the right side, into the vena cava, and on the left, into the emulgent vein. This is not always the case, though stated by Nagel as such ; for in the capsules examined, often and generally it may be said, two or three veins run off from the capsule corresponding in their course to the arteries supplying the organ. Lym- phatics.— These vessels are large and numerous, and termi- nate in the lumbar glands (Wilson). This statement is not correct, for in fact little is known concerning them. Arnold asserts that he found superficial and deep seated ones. Eck- er denies this, by saying that he only found the superficial, and Kolliker agrees that these even are few, having seen in his examinations a few small trunks. Nerves.—No organs known are so liberally supplied with nerves; as many as thirty-three trunks, (Kolliker) have been counted. They come from the cceliac and renal plexuses, and the semilunar ganglia ; and from the pneumogastric, and phrenic, according to Bergmann. Connected with the sym- pathetic they have ganglia especially apparent on the inner and lower border of the organ, (Kolliker). The}' can be traced no farther than the medullary portion, and appear to belong entirely to that portion. 2d. The physiology of these organs is involved in so many hypotheses, that it is with hesitation that anyone could select any one opinion as descriptive of their true function.
