their interspace. This part of the intestine measured fourteen feet 

 in length. 



The length of the intestines was as follows : 



The liver weighed six pounds eleven ounces avoirdupois ; it con- 

 sisted of one lobe of a flattened form, with a small posterior spigi- 

 lean process. 



The presence of a gall-bladder, distinguishing the hollow-horned 

 from the solid-horned Ruminants, made the investigation of this point 

 in the anatomy of the GiraiFe one of extreme interest ; and Mr. Owen 

 remarks, that the result of his examination of three individuals shows 

 the caution which should be exercised in generalizing upon the facts 

 of a single dissection. 



In the first Giraffe (Mr. Cross's female) a large gall-bladder was 

 present, having the ordinary position and attachments, but presenting 

 the unusual structure of a bifid /wnrfMS. Upon making a longitu- 

 dinal incision down its side, it was found to be di\dded throughout 

 its length by a vertical septum of double mucous membrane, form- 

 ing two reservoirs of equal size ; the organ in fact was double, each 

 bladder having a smooth lining membrane, and communicating sepa- 

 rately with the commencement of a single cystic duct. 



In the two GirafFessubsequently dissected not a vestige of this organ 

 could be detected, the bile in them being conveyed by a rather wide 

 hepatic duct to the duodenum. Mr. Owen therefore concludes that the 

 absence of the gall-bladder is the normal condition, and that the 

 Giraffe in this respect has a nearer aflSnity to the Deer than to the 

 Antelopes. 



The pancreas was broader, thinner, and of a more irregular form 

 than in the calf or human subject ; it was attached on the left side 

 to the diaphragm and posterior part of the stomach, extending trans- 

 versely across the spine to the termination of the biliary duct. 



The spleen was of a tolerably regular oval form, but very thin, not 

 exceeding one inch and two-thirds at the thickest part. 



In the chest the viscera presented the usual disposition. 



Sanguiferous System. 



The heart measured in the full length of the ventricles eight inches 

 and a half, and the same in the transverse diameter of the base. The 

 auricles were small as compared with the ventricles, which form a 

 rounded cone. The right ventricle terminated two inches from the 

 apex. Tlie left flap of the tricuspid valve had its free margin at- 

 tached by long chordce tendineee to the septum ventriculorum on one 

 side, and to a single columna carnea on the other, which columna also 

 gave attachment to some of the chordce tendineee of the right flap of the 

 tricuspid ; the rest of the chordce of this flap, and all the chorda of
