NATURAL HISTORY OF SELBORNE. 39 



The house-martins have eggs still, and squab young. The last 

 swift I observed was about the 2ist August : it was a straggler. 



Red-starts, fly-catchers, white-throats, and reguli non cristati, still 

 appear : but I have seen no black-caps lately. 



THE HOUSE-MARTIN. 



I forgot to mention that I once saw, in Christ Church College 

 quadrangle in Oxford, on a very sunny warm morning, a house- 

 martin flying about, and settling on the parapet, so late as the 

 2oth November. 



At present I know only two species of bats, the common vesper- 

 tilio murinus and the vespertilio auribus? 



I was much entertained last summer with a tame bat, which 

 would take flies out of a person's hand. If you gave it anything 

 to eat, it brought its wings round before the mouth, hovering and 

 hiding its head in the manner of birds of prey when they feed.
