[NOV. 15, right lobes, is deeply divided by the fissure, through which the round ligament (w) passes, into a left and right portion ; the former (Mf) is subtriangular, with a pointed free extremity, and not further subdivided ; the latter (-3Z1) is rather the larger of the two, and, very near its left border, has a deep cleft in which the gall-bladder (B) is situated, the fundus being visible on the upper surface of the liver in this cleft. There is thus a distinct, narrow, tongue-shaped lobule (M2) between the umbilical and the cystic fissures*. 3. The right lobe (R) is rather smaller, though thicker, than the left, and of a subquadrate form. It has the usual two accessory lobules on its under surface-the pyramidal pointed Spigelian lobule (S), and a remarkably large caudate lobule (A), grooved above for the inferior vena cava, and projecting beyond the right lateral margin of the main superior division of the lobe "f*. The inferior vena cava (vc) perforates the upper or posterior border of the right lobe, running for a distance of an inch and a half under a bridge of the hepatic substance, at its emergence from which it is joined by the hepatic veins. The gall-bladder is of the usual pyriform shape. The commencement of the duct is sharply bent upon the neck of the bladder, and it makes another sharp bend in the contrary direction at the junction of the hepatic ducts. Its fundus (B) appears on the upper surface of the liver in the cleft between the divisions of the lobe marked 31' and M1 in the figure. It also displaces the substance of Ml a short distance to the right of the fissure, and appears on the surface only coveted by the external capsule of the liver. The spleen is elongated and perfectly simple, without any notch or fissure, rather broader at the lower than at the upper end. Its length is 5*7", and its greatest breadth 1". The right kidney is placed very slightly higher than the left. These organs are perfectly simple, having no indications of division into lobuli on their surface. The length of each is 1*9", its greatest breadth 1*1". The suprarenal bodies are placed close to the upper end of each kidney ; they are small, oval, and somewhat flattened, *35" in greatest length. P E L V I C VISCERA. Organs of generation.-Externally the generative organs are small and inconspicuous (see fig. 9). On the hinder part of the under surface of the abdomen, 2\ inches in front of the anus, is a short conical prepuce, directed forwards, and projecting scarcely more than 5 inch above the level of the surrounding skin ; it is nearly naked, and pale-coloured, but it has a few long stiff hairs growing around the orifice on its summit. Behind this the penis forms scarcely any appreciable median prominence. There is no proper scrotum ; but the testes form distinct rounded prominences, about \ inch in diameter, under the skin, with a flat interval of * In Nasua this is of relatively larger size. t In Nasua the proportions of these lobules are very similar. |
