CORRESPONDENCE OF RAY. 359 



any of my poor endeavours. I shall shortly send you 

 Father Camelli's papers. I am in constant pain, no 

 means I have hitherto used affording any ease or relief. 

 My wife salutes you with tender of her humble service. 

 I rest, 



Sir, 

 Your obliged friend and humble servant, 



John Ray. 



For Lis honoured friend. Dr. Hans Sloane, 



at his house at the comer of Southampton street, 

 towards Bloomsbury square, London. 



Mr. Lhwyd to Mr. Ray. 



Dear Sir, — 1 know not whether I ever mentioned to 

 you (though you have probably frequently observed it 

 yourself) in what manner the bats are lodged in the 

 caves during winter. The caves of this country (to 

 mention that by the by) are always (I speak of the 

 inland caves), in limestone, and in such places only are 

 all our subterraneous brooks, which in Wales are no 

 great rarity. In these caves the bats choose the di'iest 

 apartments, where, planting their talons to the roof, they 

 cover their bodies with their wings, and so, hanging per- 

 pendicularly in great numbers (but so as they touch not 

 each other), they sleep for some months. ^
