their interspace. This part of the intestine measured fourteen feet 



in length. 



The length of the intestines was as follows : 



The liver -vveighed 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 

 frora the solid-hornedRumlnants, made the investigation of this point 

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

 remarks, that theresultof his examination of three indiv-iduals shows 

 the cautionwhich should be exercised in generalizingupon the facts 

 of a single dissection. 



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

 present, having the ordanary position and attachments, but presenting 

 the unusual structure of a hifid f undus. Upon making a longitu- 

 dinal incision down its side, it \vas found to be di^'ided throughout 

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

 ing two reserv'oirs of equal size ; the organ in fact was double, each 

 bladder having a sraoothlining membrane, and communicating sepa- 

 rately with the commencement of a single cystic duct. 



Inthe two GirafFes subseąuently dissectednot avestigeof this organ 

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

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

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

 GirafFe in this respect has a nearer affinity 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, extenduig 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 fuU length of the ventricles eight inches 

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

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

 rounded eone. The right ventricle terminated two inches from the 

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

 tached by long chorda tendinece to the septum ventriculorum on one 

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

 gavę attachment to some of the chordcE tendinea of the right flap of the 

 tricuspid ; the reat of the chordte of this flap, and all the chorda of
