Fig. 148. 



A view of the Right Kidney with its Renal Capsule; 

 1, anterior face of the kidney ; 2, external or convex 

 edge ; 3, its internal edge ; 4, hilum renale ; 5, inferior 

 extremity of the kidney; 6, pelvis of the ureter; 7, 

 ureter; 8, 9, superior and inferior branches of the 

 emulgent artery ; 10, 11, 12, the three branches of the 

 emulgent vein; 13, anterior face of the renal capsule; 

 14, its superior edge ; 15, its external edge; 16, its in- 

 ternal extremity; 17, the fissure on the anterior face 

 of the capsule.] 



[Fig. 149. 



A section of the Kidney, surmounted by the 

 Supra-Renal Cupsule; 1, the supra-renal cap- 

 sule; 2, the vascular portion; 3, 3, its tubular 

 portion, consisting of cones ; 4, 4, two of the 

 calices, receiving the apex of their correspond- 

 ing cones; 5, 5, 5, the three infundibula; 6, the 

 pelvis ; 7, the ureter. 



A view of half a Kidney divided vertically from its convex 

 to its concave edge; one of its extremities is perfect; 1, 1, 

 the lobes which form the kidney ; 2, 2, the lines of separation 

 of these lobes ; 3, the cortical substance ; 4, 5, the pyramids 

 of Malpighi; 6, the hilum renale split up and cleared of its 

 vessels ; 7, 7, points to the tubes of Bellini ; 8, one of the 

 papillae; 9, 10, two other papillae, uncut, but deprived of the 

 calices that surrounded them; 11, OTIC of the foveolae in the 

 papilla; 12, 12, the vascular circle surrounding the papilla?; 

 13, circumference of the tubular portion; 14, external surface 

 of the kidney ; 15, the portion of its external surface on a 

 line with its fissure.] 



Represents the half of a Kidney divided 

 vertically, and with its arteries injected ! 

 the matter has also passed into the ex- 

 cretory ducts ; 1, 2, branches of the emul- 

 gent artery ; 3, 3, hilum renale ; 4, 4, cor- 

 tical substance, as essentially formed by. 

 the capillary terminations of the vessels 

 of the kidney ; 5, medullary or tubular 

 portion.]
