Swallows are feen during the fummer in every part of Europe 

 from Lapland to the Southern coaft of Spain ; nor is Europe 

 vaftly inferior in point of fize to Africa. 



If fwallows therefore retreat to Africa in the winter, mould 

 not they be difperfed over the whole Continent of Africa during 

 that feafon, juft as they are over every part of Europe during the 

 fummer ? 



But this mofl certainly is not fo : Dr. Shaw, who was a very 

 good naturalift and attended much to the birds in the neighbour- 

 hood of Algiers (as appears by his account of that country), makes 

 no mention of any fuch circumftance ; nor have we heard of it 

 from any other traveller q . 



It muft be admitted indeed, that Herodotus, fpeaking of a part 

 of upper Egypt (which he had never feen), lays, that kites and 

 fwallows never leave it r ; this, however, totally differs fromMonf. 

 Adanfon's account, who informs us that they difappear in Senegal 

 on the approach of fummer ! . 



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

 to M. Adanfon's eyefight, 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 fpeht great part of their 

 lives there, and whofe notice European fwallows feen during the winter 

 muft have probably attracted. I do not mean by this to deny that fuch 

 fwallows may not be obferved at Senegal ; 1 only doubt their periodical 

 migration.

s On the contrary they appear, and difappear, at the fame feafons as 

 with us, both in the tropical parts of America and Alia. With regard 

 to America, I mall cite Hughes's Hiflory of Barbadoes, p. 75. and, 

 with relation to Alia, a gentleman long refident in Bengal, who informs 

 me that fwallows are often found in the banks of the Ganges during the 

 winter, and in their torpid ftate. They alfo conceal themfelves in the 

 rocks of Barbadoes, according to Hughes.
