Prof. Garrod'3* method, tlie accompanying diagram will indicate 

 the arrangement of the laminse. 



The abomasum presents the 

 usual form. Its mucous lining 

 is, for the most part, smooth, 



but close to its commencement i • i •

 At the pylorus the walls of this terium. 

 compartment are much thickened. 



Small Intestine. — The duodenum measured 2 feet in length, 

 and was dilated into a kind of pouch immediately beyond the 

 pylorus. The whole length of the small intestine, including the 

 duodenum, was 43 feet 11 inches. In Perrault'sf specimen it 

 measured -IS feet. 



Large Intestine. — The caecum measured 22| inches in length ; 

 according to PerraultJ 13 inches. Its mucous lining just below 

 the opening of the ileum is thrown into a number of small glan- 

 dular pouches closely resembling the ileo-csecal gland of the 

 Giraffe as described by Cobbold§. The pouches, however, are 

 smaller in size in the Elk than in the Giraffe. The rest of the 

 large intestine is arranged in numerous coils, and measures, ex- 

 clusive of the caecum, 42 feet 6 inches in length. It diminishes 

 slightly in diameter as far as the rectum, where it is again 

 slightly dilated. 



Liver (PI. YI. fig. 4). — This measures 17 inches from side to 

 side, and 9|- from above downwards ; according to Perrault, 1 foot 

 by 7 inches. It is divided into two lobes, right and left, 

 although, as remarked by Perrault, the longitudinal fissure is but 

 feebly pronounced. On the posterior surface of the right lobe is 

 a well-developed caudate lobule of a triangular shape, which lies 

 to the right of the portal fissure, whilst the upper border of the 

 right lobe is prolonged into a triangular Spigelian lobule mea- 

 suring f of an inch in length. The gall-bladder, as remarked by 

 Perrault, is absent. 



The spleen is elongated oval in form, and measures 8 inches in 

 length and 5^ inches in breadth — measurements which agree 

 with those of Perrault.
