NATURAL HISTORY OF SELBORNE. 33

 story. While I amused myself with this wonderful

 to frequent waters, not only for the sake of drinking, 

 but on account of insects, which are found over them in 

 the greatest plenty. As I was going some years ago, 

 pretty late, in a boat from Richmond to Sunbury, on a 

 warm summer's evening, I think I saw myriads of bats 

 between the two places ; the air swarmed with them all 

 alonjj the Thames, so that hundreds were in si^^ht at a 

 time.

 of which I have preserved in brandy. From the colour,
