of the southern extreme of the New World with that of the nearest 

 portions of the southern hemisphere, in likę manner as the zoology 

 of the northtrn extreme is united ■vvith that of the neighbouring 

 continents of Europe and Asia. He pointed out some additional 

 instances, in \vhic;h the šame union raight be traced. 



Mr. Owen commenced the reading of a paper On the Anatomy 

 of the Orang Utun {Simin Sati/rvs, L.). 



The subject principally referred to \vas a young malė, probably 

 about four years of age, \vhich had recently been presented to the 

 Socieiy by Mr. Swinton of Calcutta ; it reached England in a very 

 debilitated statė, and died on the third day after its arrival in Bruton- 

 street. 



The nicrbid appearances met with in its examination were very 

 slight, and of thercselves not sufficient to account for the death of 

 the animal. The brain \vas firm, and its membranes bore no traces 

 of inflammiition. The stomach and intestines \vere also eąually free 

 from morbid appearances. Tlie liver \vas perfectly healthy, which 

 was the more remarkable, as on the third day before death the 

 faces \vcre clay-coloured from a deficiency of bile. The heart \vas 

 healthy, except that it had tvvo or three patches of organized lymph 

 upon its surface, indicating old inflammation : the pericardhnn con- 

 tained more than half an oiince of fluid : about four ounces of fluid 

 \vere also effused in the cavity of the chest, and the cellular tissue of 

 the lungs \vas gorged \vith serian, a circumstance \vhich mušt have 

 occasioued a great obstniction of the circulation. There existed be- 

 fore death evidence of this effusion, in the slo\v and laboured breath- 

 ing of the animal, as noticed by Mr. Martin, who also statės that 

 the pulse was 100 and very fe;ble,but, as far as he observed, \vithout 

 intermission. No other organ exhibited any lesion of structure ; 

 the lungs and liver were free from tubercles, the development of 

 which appears to be the most frequent cause of death in animals 

 ■which, coming from warm countries, have sojourned in our damp 

 climate. Tlie effusion observed may probably be considered as one 

 of the conseąuences of that debility and exhaustion of the system, 

 produced by a long voyage, improper food, and diarrhaa, which 

 terminated in premature death. 



The general appearance and position of the abdominal viscera in 

 the Orang bear much resemblance to those of the human subject. 

 The stomach is thicker and narrower at its pyloric end, and the vil- 

 lous coat is of less extent. The small intestines are lined by a smooth 

 and uniform membrane, and are \vithout valvulce conniventes. The 

 position of the ccecum is the šame as in man : to its extremity is at- 

 tached the vermiforra appendage, \vhich is wider at its commence- 

 ment ; thus exhibiting as a permanent structure in the Orang, that 

 which in man is a fcEtal peculiarity. The colon is saccuiated, and ap- 

 pears, from the existence of glandulce solitariee and from the presence 

 of lacteal glands in the meso-colon, to take a great share in the 

 functions of digestion. The liver generally resembles the human; 

 the gali bladder is long and tortuous; Ū\epancreas is relatively larger, 

 and the spleen more pointed at its extremities than in man; the
