amount of fibrous tissue, and lined by flattenednucleated epithelial plates. This capsule is the dilated extremity of theuriniferous tubule which is invaginated to receive the glomerulus of con-voluted capillary blood-vessels. The invaginated portion of the tubule is ofparticular importance since it is the membrane through which a large partof the urine is secreted. The glomerulus is connected with an efferent andan afferent blood-vessel. The Malpighian capsule is connected by a con-stricted neck, figure 287, N, with the proximal convoluted tubule. This forms TUBULI URINIFERI 373 several distinct curves and is lined with short columnar cells. The tubenext passes almost vertically downward toward the medulla, forming thespiral tubule, still within the cortex of the kidney, which is of much the samediameter. The loop of Henle, L, in the medulla, is a very narrow tube linedwith flattened nucleated cells. Passing vertically upward from the loop of COB TEX i ; IBYRINTH )it£.D.RAY\ LABYR.

G, Glomerulus; BC, Bowmanscapsule; N, neck, PC, proximal convoluted tubule; S, spiral tubule; D, descending arm of Henlesloop; L, Henles loop; A, ascending arm of Henles loop; IDC, distal convoluted tubule; AC, archedtubule; SC, straight collecting tubule; ED, duct of Bellini; A, arcuate artery, and V, arcuate vein,giving off interlobular vessels to cortex and vasa recta to medulla; a, afferent vessel of glomer-ulus; e, efferent vessel of glomerulus; c, capillary network in cortical labyrinth; 5, stellate veins, vr,vasa recta and capillary network of medulla. (Pearsol.) Henle, the tubule varies somewhat in histological character, but the irregulartubule and the distal convoluted tube, identical in all respects with the prox-imal convoluted tube, are to be noted. The proximal convoluted tubepasses into the curved and straight coll
