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. 
Or rHE DISAPPEAR AW ee 
SWALLOWS. ) 
THERE are three opinions among naturalifts 
concerning the manner the fwallow tribes difpofe 
of themfelves after their difappearance from the 
countries in which they make their fummer refi- 
dence. Herodotus mentions one fpecies that refides 
in Egypt the whole year: Pro/per Alpinus* afferts 
the fame; and Mr. Loten, late governor of Ceylon, 
affured us, that thofe of Fava never remove. 
Thefe excepted, every other known kind obferve 
a periodical migration, or retreat. The fwallows 
of the cold Norway +, and of North Americat, of 
the diftant Kamt/chatka §, of the temperate parts 
of Europe, of Aleppo ||, and of the hot Famaica**, 
all agree in this one point.
