in them, at leaft independent of cold, or want of 
nourifhment, fince in-a cage, the temperature 
-muft be always nearly the fame, and their fool 
generally in equal abundance. | aa 
The Nightingale is not originally an American 
bird ; there are fome in the northern parts, thele 
__ may have migrated from the north eaftern parts of 
Afia, where a very narrow . fea divides the Con- 
tinents. The fong of the Nizhtingale in Canada, 
is faid to be much inferior to the fong of the 
Nightingale in Afia, or Europe, and their fong 
in Scotland, to their fong in Italy; indeed a 
fcarcity of food, anda cold climate, materially 
affe& the finging of birds. 
As the male Nightingale pafles much of the 
night in finging, it has been fuppofed that’ they 
never fleep in the fummer feafon ; and with equal 
~ folly, that the heart and the eyes of. a nightingale 
placed under a pillow, would prevent the perfon 
from fleeping who lay upon it: itis right to men+ 
tion thefe follies, in order to expofe and contra- 
~di@them. Attentive obfervers find that in the 
fummer feafon, Nightingales fleep occafionally in 
the day, and in confinement they have been ob- 
ferved to dream, and to warble in their fleep in 
a tow. VOICE.
