some projecting spot, against which it would rub its muz- 

 zle. After the time above-mentioned, it was observed to 

 eat no more, and it soon died. Cleanliness appeared a very 

 peculiar characteristic of this animal ; with its hinder-feet 

 it would rub all the parts of its body, and cleanse its nails, 

 fingers, and the membrane forming its wings, very dexte- 

 rously, with its mouth. There was very considerable viva- 

 city in the motions of its head, appearing to indicate very 

 lively sensations ; and its projecting cheeks, its mobile 

 nose, and great ears, exhibited partial movements of asto- 

 nishing variety, which gave to its physiognomy an expres- 

 sion extremely singular in so small an animal. 



The system of dentition, as far as it respects the molars, is 

 the same in all the insectivorous bats. In the Barbastelle, the 

 upper incisors are four in number : the first is larger than 

 the second, and bifid. There are six incisors in the lower jaw, 

 and all indented. There are two false molars on each side 

 of the two jaws, so that, in all, this animal has four-and- 

 thirty teeth. The first false molar, in the upper jaw, is so 

 small, and so completely concealed at the basis of the canine, 

 that it is scarcely perceptible ; for this reason, it escaped the 

 researches of Daubenton, who gives but eight upper cheek- 

 teeth to this bat. On each side of the muzzle is a large tu- 

 bercle or cushion, surrounding the nostrils in part, and be- 

 hind which, is the eye. The eye itself is so small, that it 

 is perceived with difficulty in the midst of the hairs which 

 surround it, and it is impossible to distinguish exactly the 

 form of the pupil. The nostril is bored at the extremity of 

 a furrow, which has the form of a V, one of the branches 

 of which, is much larger than the other. The lips are en- 

 tire ; the tongue is smooth, and there do not appear to be 

 any cheek-pouches. The most extended sense of this ani- 

 mal is evidently that of hearing. The external conch of 

 the ear, is of a most disproportioned magnitude ; it ex- 

 tends, in front, as far as the middle of the forehead, is
