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

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

 of the northern extreme is united with that of the neighbouring 

 continents of Europe and Asia. He pointed out some additional 

 instances, in which the same union might be traced. 



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

 of the Orang Utun {Simia Sati/rt/s, L.). 



The subject principally referred to was a young male, probably 

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

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

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

 street. 



The morbid appearances met with in its examination were very 

 slight, and of themselves not sufhcient to account for the death of 

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

 of inflammation. The stomach and intestines were also equally free 

 from morbid appearances. The liver was perfectly healthy, which 

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

 faces were clay-coloured from a deficiency of bile. The heart was 

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

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

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

 were also effused in the cavity of the chest, and the cellular tissue of 

 the lungs was gorged with seriun, a circumstance which must have 

 occasioned a great obstruction of the circulation. There existed be- 

 fore death evidence of this effusion, in the slow and laboured breath- 

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

 the pulse was 100 and very feeble, but, as far as he observed, without 

 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. The effusion observed may probably be considered as one 

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

 produced by a long voyage, improper food, and diarrhwa, 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 without valvule conniventes. The 

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

 tached the vermiform ajipendage, which is wider at its commence- 

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

 which in man is a foetal peculiarity. The colon is sacculated, and ap- 

 pears, from the existence of glandulce solitarice 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 gall bladder is long and tortuous; the ;jff«nras is relatively larger, 

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