Show 788 MR. A. H. GARROD ON THE [Dec 2, it gradually diminishing a foot from the ileo-caecal valve and ceasing altogether 4 inches further on, the ridges continuing as simple folds like railway lines. Commencing colon of Aulacodus swindernianus, slit open on the non-attached border, showing the ileo-csecal valve on the left, beyond which is the commencing caecum; the intestine, with the two longitudinal ridges, running to the right; a, terminal portion of small intestine. The liver possesses a gall-bladder which is short and pyriform. It presents all the typical fissures and lobes. The median fissure is slightly bridged over with hepatic tissue on the abdominal surface behind. The right and left lateral fissures very nearly separate off the lateral lobes as distinct glands; the caudate lobe is also only slightly attached. The left lateral lobe is the largest, next the right central, in which the cystic fossa and fissure are both deep. The right lateral is the smallest of the four main lobes ; the caudate is smaller than any of them ; and the spigelian is only a flat flake of hepatic tissue. The right lung possesses four lobes, of which the lowest is the largest, and the top one as small as the fourth, azygos one. An accessory bronchus joins the right bronchus. The left lung has two lobes, the upper the smaller, having two upper diverticula ; there is no left accessory bronchus. The aorta primarily branches into two trunks for the upper extremities, an innominate and a left subclavian; the left carotid soon leaves the innominate. |
