armed with a claw, shaped like a cat's. The second digit is tied within an eighth of 

 an inch of the third, and as it terminates sooner its weak distal phalanx is supported 

 by a still closer proximity to the penultimate phalanx of its neighbour. The third 

 and fourth digits are nearly an inch and a half apart at their tips, and the last pha- 

 lanx of each appears to be cartilaginous, or is at least bent along the edge of the 

 membrane in a direction towards the other. From the tip of the fourth to the tip of 

 the fifth is about 2\ inches, and from this to the foot is also about 2\ inches. The 

 edge of the membrane reaches the outer side of the foot at the distal extremity of the 

 metatarsal bones, and the part of the foot beyond these bones is free. Between the 

 foot and the tail, the membrane starts from the tarsus along the " spur," which sup- 

 ports it for about three quarters of an inch, and it finally reaches the very tip of the 

 coccyx. The dimensions are —

The five digits, of nearly equal length, are each tipped with a strongly hooked claw. 

 There are nine caudal vertebra. — John Wolley ; 3, Roxburgh Terrace, Edinburgh,

Remarks on Bats. — On the cover of the January number of the 'Zoologist' you 

 request information on British bats. Perhaps the following observations and experi- 

 ments of M. de Jurine, in the ' Journal de Physique ' for 1 798, may prove service- 

 able to you or your friend, R. F. Tomes, Esq. The experiments of Jurine were made
