thefe birds were taken, and that he knew them to be the true 

 fwallow of Europe % which he fuppofes were then returning to 

 the coaft of Africa. 



I mail now endeavour to mew that thefe birds could not be 

 European fwallows ; nor, if they were, could they have been on 

 their return from Europe to Africa. 



The word hirondelle, in French, is ufed as a general term for 

 the four f fpecies of thefe birds, as the term fwallow is with us. 



Now the four fwallows thus caught and examined by Monf. 

 Adanfon were either all of the fame fpecies, or intermixed in fome 

 other proportion. . v 



Would not then any naturalift in ftating fo material a fact (as 

 he himfelf fuppofes it to be) have particularized of what fpecies of 

 fwallow thefe very interefting birds were ? 



Should not Monf. Adanfon alfo have taken care to diftinguiili 

 thefe fuppofed European fwallows from a fpecies of the fame tribe, 

 which bears a general refemblance to thofe of Europe, and is not 

 only defcribed, but engraved by BrilTon, under the name of 

 Hirondelle de Senegal g ? 



Monf. Adanfon however concludes his account of the fuppofed 

 European fwallow, whilft it continues on the coaft of Senegal, by 



e I have before endeavoured to Ihew that Monf. Adanfon does not 

 always recoiled: with accuracy the plumage of the more common Euro- 

 pean birds, by what he fays with regard to the linnet. I need fcarcely 

 obferve alfo that the 6th of October, when thefe fwallows were caught, is 

 too' early for their migration fo far-fouthward from any part of Europe. 



f Yh. the fwallow uoff s^oyjjv, the martin, the fand martin, and the 

 fwifc : I omit the goat-fucker, becaufe this bird, though properly clalfed 

 as a fpecies of fwallow by ornithologifts, is not fo conridered by others. 



s See BrilTon, Tom. II. pi. xlv. Sonnerat alfo hath given .a defcrip- 

 tion and engraving of the fwallow of Antigue [fome illand between the 

 Philippines and N. Guinea] which much refembles our martin, except 

 that the throat is yellow.
