Swallows are {ten during the dimmer, in every part 

 of Europe from Lapland to the Southern coafl of 

 Spain ; nor is Europe vailly inferior in point of fize 

 to 'Africa. 



If fwallows therefore retreat to Africa in the 

 winter, ihould not they be difperfed over the whole 

 Continent of Africa, jufl as they are over every part 

 ■of Europe ? 



But this moil: certainly is not fo-: Dr. Shaw, who 

 was a very good naturalift and attended much to the 

 birds in the neighbourhood of Algiers (as appears by 

 bis account of that country), makes no mention of 

 any fuch circumftance, nor have we heard of it from 

 any other traveller *: 



It mull be admitted indeed, that Herodotus fpeak> 

 ing of a part of upper Egypt (which he had never 

 feen) fays, that kites and fwallows never leave it-j-j 

 this, however, totally differs from Monf. Adanfon's 

 account, who informs us that they difappear in Se- 

 negal on the approach of fummer. 



It feems to follow therefore, from this filence in 

 others, that fwallows cannot be accommodated for 

 their winter refidence in any part of that vail con- 

 tinent, but in the neighbourhood of Senegal. 



But this is not the whole objection to fuch an 

 hypothecs. 



* It may alfo be obferved here, that credit is in fome meafure 

 given to M. Adanfon's eyeftghr, againft that of all the Englifh, 

 French, Dutch, Portugueze, and Danes, who have been fettled 

 not far from Senegal for above a century, many of which have 

 fpent the greateft part of UVir lives there, and whofe notice, 

 fwallows feen during the winter, muft have probably attracted.
