4o6 SWALLOWS. Class II. 



To the curious monographics on the fwallow 

 tribe, of that worthy correfpondent, I muft ac- 

 knowlege myfelf indebted for numbers of the re- 

 marks above-mentioned. 



Of the disappearance of 

 SWALLOWS. 



' THERE are three opinions among naturalifls 

 concerning the manner the fwallow tribes difpofe 

 of themfelves after their difappearance from the 

 countries in which they make their fummer re(i- 

 dence. Herodotus mentions one fpecies that refides 

 in Egypt the whole year : Profper jilpinus * aflerts 

 the fame \ and Mr. Loten^ late governor of Ceylon^ 

 aflured us, that thofe of Java never remove. 

 Thefe excepted, every other known kind obferve 

 a periodical migration, or retreat. The fwallows 

 of the cold Norway -]-, and of North America J, of 

 the diftant Kamtfchatka % ^ of the temperate parts 

 of Europe, oi Aleppo \\, and of the hot Jammca*'^^ 

 all agree in this one point. 



* Hirundines duplicis generis ibi obfervantur ; patriae fcili- 

 cet quae nunquam ab jEgypto difcedentes, ibi perpetuo mo- 

 rantur, atque peregrinae, hae funt noftratibus omnino fimiles ; 

 patriae vero toto etiam ventre nigricant. Hijl. JEgypt. I. 198.
