or XJngka Ape of Sumatra, 141 



On the 19th of March (1831) we had reached the latitude 

 45° 4r N. and longitude 24° 40' W. ; the animal seemed 

 (although clothed in flannel) to suffer much from cold, and 

 he was attacked by dysentery : his attachment was so great, 

 that he would prefer going on the deck, in the cold air, with 

 the persons to whom he was attached, to remaining in the 

 warm cabin with those whom he did not regard. On the 

 24th he became much worse, his appetite gone, and he had a 

 dislike of being moved ; the discharge from the bowels was 

 bilious, mixed with blood and mucus, sometimes entirely of 

 blood and mucus, with a putrescent odour : the breath had a 

 sickly odour, mouth clammy, eyes dull and suffused ; drank a 

 little water occasionally, and sometimes a little tea ; he gene- 

 rally remained with his head hanging on the breast, and limbs 

 huddled together; he would, however, when yawning, inflate 

 the pouch as usual. On the 29th we had prevailing easterly 

 winds; and he was daily sinking until the 31st of March, 

 when he died, in latitude 48° 36' N., longitude 9° V W. 



On examination, the thoracic viscera were healthy ; the 

 spleen was healthy, of small size, and lobulated at one extre- 

 mity ; the liver was large and healthy, the difference in size 

 between that organ and the spleen was considerable in com- 

 parison with the relative proportions of those organs in the 

 human subject; the gall bladder contained a small quantity 

 of dark, thick, and viscid bile ; some of the mesenteric glands 

 were enlarged, some being of a white, others of a dark colour. 

 On laying open the duodenum, it was found to contain a 

 quantity of mucus slightly tinged with bile ; the colon and 

 caecum were full of liquid bilious faeces mixed with mucus, 

 and several small ulcerated patches on the inner surface, 

 and a dark spotted appearance at others ; the rectum also 

 contained similar faeces, but mixed with a curdy matter, and 

 there were several large patches of ulceration on the inner coat, 

 more particularly near the termination of the gut : the kidneys 

 were healthy, on the right the capsula renalis was large, but 

 none was visible on the left; the bladder was quite empty, the 

 inner surface scarcely moist. The animal had been castrated, 

 but the spermatic cord terminated in the scrotum in two small 

 oval substances, rather larger than peas ; the sacrum and os 

 coccygis were similar to those parts in the human subject. 

 The communication of the larynx was examined ; the epi- 

 glottis was only indicated by a slight obtuse angular rising ; the 

 sacculi laryngis three eighths of an inch in the long diameter, 

 one eighth in the short; their margins were well defined, 

 continued forwards below the body of the os hyoides into a
