Tome, which were found in the winter, under water, 
and in which he could not obferve any circulation of 
the blood *. 
Afluming it, therefore, from thefe fads, that 
fwallows have been found in fuch a fbate, I would 
afk the partifans of migration, whether any inftance 
can be produced where the fame animal is calculated 
for a ftate of torpidity and, at the fame time of the 
year, for a flight acrofs oceans ? 
But it may be urged, poffibly, that if fwallows 
are torpid when they difappear, the fame thing 
fhould happen with regard to other birds, which are 
not feen in particular parts of the year. 
To this I anfwer, that this is by no means a ne-

being fevere. 
I fhall clofe the proofs on this head (which I could much en- 
large) by the dignified teftimony of Sigifmond, King of Poland, 
who affirmed on his oath, to the cardinal Commendon, that he 
had frequently feen fwallows, which were found at the bottom 
of lakes. See the life of cardinal Commendon, p. 21 x. Paris,
