In the medullary substance, there are straight veins as there are straight arteries. On the surface of the organ, beneath the fibrous envelope, are the stellate veins of Verheyen—the junction of five or six venules which converge towards a central vein. The venules of the two portions collect into more voluminous vessels, which form complete arches at their limits; it is to the presence of these vascular canals that the dark colour observed at this point of the renal tissue must be attributed. h. The lymphatics are abundant in tlie mass, but rare at the superficies of the organ ; they form plexuses, the ultimate branches of which pass to the sublumbar glands. c. The nerves emanate from the solar plexus, and form a particular network around the arteries, exhibiting, on their course, some microscopic ganglia. It is not known how they terminate. DevelopmenTo—The kidneys appear very early in the foetus, above and a.
