the cortical substance from 1 inch to 1 inch ami a half in extent : 

 the tubular part terminating: in a very smaW pelvis, but not projecting 

 in the form oi ivaiinnillce. The ureters contained opake fluid Vike pus, 

 but tlie kidneys did not appear diseased. The suprarenal capsules 

 were 3 inches in length, and 1 in width ; along the middle of these 

 bodies tliere was a line of substance differing in colour from the rest: 

 the cortical part was striated, the slrice converging to the central line. 



"The whole of the lungs had a mottled appearance, arising from 

 the deposition of numerous large masses of tubercular matter similar 

 to that observed in the mesenteric glands. 



"The heart is large in proportion to the animal, and of a rounded 

 form with an obtuse apex ; the length of this organ was 7 inches, its 

 breadth across the base 6 inches. The trachea was small in its dia- 

 meter, but the cartilages are thick and strong, and incomplete behind. 



"The OS hyoides is articulated to the base, not the ajjex, of the sty- 

 loid processes. 



" The proboscis is provided with two strong round levatores arising 

 from the ossa yiasi ; there are also depressores arising from the inter- 

 maxillary bones, and Jasciculi of muscular fibres in its substance, 

 forming a texture similar to the proboscis of the Elephant ; the strong 

 levatores are well adapted to enable this part to turn up the soil, when 

 the animal is in search of roots, &c. 



" The testes are elongated glands, 4 inches in length, situated ex- 

 ternally in a slightly indicated scrotinn at the distance of 6 inches 

 from the anus. The cremaster was remarkably powerful, being com- 

 posed of a sixon^ fasciculus of fibres continued from the lower margin 

 of the internal oblique muscle, of upwards of 1 inch in breadth. The 

 tunica vaginalis had a free communication as usual with the cavity of 

 the abdomen. The penis, of great length, terminates in an enlarged 

 truncate extremity, the orifice of the urethra being near the lower 

 margin of the disc. There are no levatores muscles ; but a quantity 

 of elastic cellular membrane extends from the abdominal muscles along 

 the dorsum penis. 



" On comparing my notes with those taken by Mr. Clift at the dis- 

 section of the Sumatran Tapir, I find the differences in the admeasure- 

 ments of the alimentary canal, especially of the ccecum, not so con- 

 siderable as are stated by Mr. Yarrell. It must, however, be remem- 

 bered that the individual dissected by the latter gentleman was much 

 younger than that from which my notes are derived. 



" Thus in the Account published by Sir Everard Home in the 

 Philosophical Transactions for 1821, the dimensions of the ccccum 

 of the Sumatran Tapir are stated to be I foot in length, and 1 foot 

 in breadth : in the American Tapir the length of the ccscum was 1 

 foot .'i inches, its greatest breadth 1 foot.
