* This curious species is not noticed by Cuvier, no doubt from its very recent 

 discovery. It has been figured in the Transactions of the American Philosophical 

 Society, and described very fully by Dr. Harlow in the same work. From se- 

 veral pccuhaiities in structure, this animal approaches very closely to the ourangs, 

 and on that account, we think should have precedence of the other Gibbons. We 

 subjoin the letter of Dr. Burrough that accompanied the specimens furnished Dr. 

 Harlow, which is interesting as a detail of a few distinguishing features of this 

 singular species. 



" The specimens of theourang-outang or Gibbons, furnished you, were obtained by 

 me during my late excursion into the interior of Bengal. They were presented to 

 me by Captain Alexander Davidson, of the Honourable East India Company, sta- 

 tioned at Goalpara, situate on the Burrampooter river, in Assam. This district of 

 country was foi-merly attached to the Burmese empire, but at present is in pos- 

 session of the East India Company, and constitutes the north-eastern limits of their 

 territory in this quarter. 



" The ourang, of which I am now to speak, called by the Assamese * Hoolock,' is 

 to he met with on the Garrow Hills, in the vicinity of Goalpara, between lati- 

 tudes 25 and 28 degs. north ; and the specimens brought to tiiis country by me, 

 were taken within a few miles of the town of Goalpara. The full grown one, which 

 at this time you have prepared, was in my possession, alive, from the month of Ja- 

 nuary to May, when it died from a blow it received across the lumbar region, inad- 

 vertently inflicted with a small stick by one of my servants at Calcutta. They inha- 

 bit more particularly the lower hills, not being able to endure the cold of those 

 ranges of the Garrows of more than 4 or 500 feet elevation. Their food, in the 

 wild state, consists, for the most part, of fruits common only to the jungle in this 

 district of country ; and they are particularly fond of the seeds and fruits of that 

 sacred tree of India, called the Peopul tree, and which, on the Garrow Hills, at- 

 tains a very large size. They likewise partake of some species of grass, and also the 

 tender twigs and leaves of the Peopul and other trees, which they chew, swallow 

 the juice thereof, and reject the indigestible part. They are easily tamed; and when 

 first takeu show no disposition to bite, unless provoked to anger, and even then
