and tlie length taken, botli by a tape, and relatively to the 

 body, from snout to anus. The whole length will measure 

 seven times that of the hody, and, of this, one-seventh will be 

 Large Intestine : or, in inches, the whole will measure from 

 47 to 50 inches, the large intestine and rectum 6 to 7 inches, 

 and the small intestine 41 to 43 inches ; the Caecum measur- 

 ing from 1^ to 2 inches. 



The Bile duct, which was left about one inch long from the 

 Liver, should next be traced up to that organ and the several 

 branches into which it breaks up, agreeably to the many 

 lobes of the multifid liver, noted. The absence of the gall 

 bladder in this species should also be noted: the anterior 

 lobe of the Liver {i.e., the lobe immediately in apposition 

 with the Diaphragm), corresponding to the " cystic " lobe in 

 Man, being here notched only for the suspensory ligament. 

 The lobe immediately posterior to the cystic lobe and extend- 

 ing mainly to the left is the " left lobe " ; while the numerous 

 lobes to the right of, and forming the posterior section of the 

 organ are homologous with the '* right lobe *' of the human 

 Liver. This follows the usual rule in the Multifid Liver, viz.: 

 that the cystic, suspensory, or middle lobe is the largest : the 

 portion of the gland to the right of this lobe being subdivided 

 into two or more lobules, of which the extreme right may be 

 the larger, and marked on its posterior aspect by a depression 

 for the kidney ; and that portion to the left more commonly 

 remaining as a single lobe. 



The Hepatic artery is readily seen coming from the Aorta 

 about a quarter of an inch posterior to the Diaphragm : and 

 within half an inch of this, farther back, may be seen the great 

 trunk of the Inferior Cava (or Post-caval of Owen), crossing 

 just ventrad of the anterior extremity of the right Kidney 

 to pass through the accumulated attachments of the right lobes 

 of the Liver, and through a groove in the middle or cystic 

 lobe prior to piercing the Diaphragm.
