teen out of twenty, when they fpeak of a fwallow, 
really mean a martin *. 
I only take notice of this fuppofed inacuracy in 
Monf. de BufFon, becaufe, if that able natural if!: does 
not fpeak of the different forts of fwallows with that 
precifion which is neceffary upon fuch an occafion, 
why fhould he rely fo intirely upon the impoffibility 
of Monf. Adanfon’s being miftaken ? 
I fhall now ftate the experiment of Monf. de 
BufFon, to prove that the fwallow is not torpid in the 
winter, and muff therefore migrate to the coaft of 
Senegal -f*. 
He fhut up fome fwallows ( hircndelles ) in an ice 
houfe, which were there confined “ plus ou moins 
“ de temps and the confequence was, that thofe 
which remained there the longefi: died, nor could 
they be revived by expofing them to the fun ; and,, 
that thofe “ qui n’avoient fouffert le froid de la 
glaciere que pendant peu de terns” were very 
lively when permitted to make their efcape. 
* In the fame manner the generical name in other languages, 
for this tribe of birds, always means the martin, and not the- 
fwallow. 
Thus Anacreon complains of the for waking him 
by its twittering. 
Now if it be confidered that there was only the kitchen chim- 
ney in a Grecian houfe, it mud have been the martin which 
built under the eaves of the window, that was troublefcme to 
Anacreon, and not the fwallow. 
Ovid alfo fpeaking of the neft of the hlrundo , fays, 
— — luteum fub trabe figit opus. 
by which he neceflarily alludes to the martin, and not the 
fwallow.
