* 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 peculiarities 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 the ourang-outang or Gibbons, a 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 formerly 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 be met with on the Garrow Hills, in the vicinity of Goalpara, between lati- 
tudes 25 and 28 degs. north; and the specimens brought to this 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 5()0 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 4 and other trees, which they chew, swallow 
the juice thereof, and reject the indigestible part. They areeasily tamed; and when 
first taken show no disposition to bite, unless provoked to anger, and even then
