by M. Desmarest. Itisto be feared, however, that in sucha case the 
weight of M. Cuvier’s authority will bear down all opposition, and that 
even the principles of nomenclature, if he persists in retaining the ap-

engaged in his favour the gratitude of every ichthyologist.

Outang. In a Letter addressed by J. Grant, M.D., to the 
Secretary of the Zoological Society. 
Sir, 
In the latter part of the year 1828, an Orang Outang that passed for 
a female and was supposed to be about three years of age, was pre- 
sented to Mr. Swinton, of Calcutta. She was sent from Singapore, where 
she had lived for some time, and was, in all probability, a native of 
Borneo. 
She was of a mild, docile, and melancholy disposition, and had been 
taught to walk in the erect posture, which she was very fond of assum- 
ing of her own accord. 
Although reputed a female, some doubts arose respecting the sex of the 
animal. At length, after as careful an examination as the restlessness 
and timidity of the creature would permit of, the great probability of her 
being a female was generally concurred in. 
There was no appearance of either vulva or labia, and at the first 
glance it was not surprising that the animal should be by some mistaken 
for a male, for a small flaccid pents-like body, about an inch in length, 
was visible under the pubes. This being found imperforate, and devoid 
of any appearance of scrotum, or testes, was pronounced a clitoris. On 
raising it, or pushing it to one side, a small aperture was observed near 
its root, capable of admitting the end of a crow-quill, and through 
which the urine passed, but whether this aperture was the urethra itself, 
or a common passage behind which was the proper urethra and vagina,
