It is alfo clear from the expreflion of demergitur (though per- 

 haps not claffical)' that this naturalift conceived thefe birds hid 

 themfelves under water during the winter ; and it is to be ob- 

 ferved, that he feems to have ftated it after a proper examina- 

 tion, becaufe in the Fauna Suecica, publifhed five years before, 

 he omits the mention of this circumftance g . 



As the inftances of finding fwallows under water are mod com- 

 mon in the Northern parts of Europe, I fhall begin with the tes- 

 timony of the inhabitants of that part of the globe. 



Mr. Peter Brown, a Norwegian and ingenious painter b , informs 

 me, that from the age of 6 to 17, whilft he was at fchool near 

 Sheen ', he with his companions hath conftantly found fwallows 

 in numbers torpid under the ice, which covered bogs, and that 

 they have often revived upon being brought into a warm 

 room k . 



Baron Rudbeck, a Swedim gentleman, who was not long fince 

 in England, hath allured me that this fact was fo well known in 

 Sweden as to leave no doubt with any one. 



s Ifaac Biberg, in his Differtation on the Oeconomy of Nature, read 

 before the Academy of Upfal, ftates the fubmerfion of fwallows as a 

 known fact in that part of the world. 



Mr. Boyle took notice that fwallows live under frozen water in the 

 Baltic. Birch's Hift. R. S. Vol. I. p. 180. ' 



The fwallows, before they fink underwater, iing their Jwallow-fong, as 

 it is called, and every one knows. Pontoppidan, part II. p. 98.

 Northern Parts of Germany. Klein.

k The befl way, however, of awakening them from their torpid ftate 

 is, to put them into one's bofom, or hold them in one's hand, as Mr. 

 Cornifh, an ingenious furgeon cf Totnels, in Devonfhire, hath informed 

 me, who hath made many curious experiments upon bats in that 

 ftate.
