SWALLOW. 325 



I seem unwilling to remark it as a fact; however, the suggestion has 

 been remarkably strengthened from my correspondence with the late 

 Mr. Tunstall, who mentioned two instances, related to him by very 

 intelligent persons, of having seen some birds, of the colour of the

 vast expanse of wing ; and indeed there can be no doubt of these 

 birds being able to reach England, as well as the Common Swift.
