Section of injected kidney of dog, showing general disposi-tion of blood-vessels: a and b, large arterial and venousbranches situated at junction of cortex (C) and medulla ( M),which break up into ascending interlobular twigs (c) and de-scending straight vessels (I, I) ; e,f, afferent and efferent ves-sels of glomeruli (g) ; h, intertubular capillary net-works; i,peripheral venous trunks, which collect the blood from sub-capsular net-works (k). the medulla, along withthe arteries, to reach thepelvis, where they joinwith their fellows to formthe renal veins. The lymphatics ofthe kidney are arranged as two sets of vessels; a superficial sys-tem ramifies within the deeper layers of the capsule, while a systemof deeper channels passes in company with the blood-vessels intothe interior of the organ to communicate with the numerous lym-phatic clefts and spaces which exist within the inte
