in Yorkmire, feven or eight years ago, the latter end of October, 

 a converfation began with the game-keeper about {wallows croff- 

 ing the feas ; which the game-keeper dilbelieved, becaufe he faid 

 he could then carry any one to Tome neighbouring coalworks, 

 where he was fure of finding them by that time. On this many 

 of the fervants- attended him to the coalpits, where federal mar- 

 tins were oblerved in a torpid ftate, but mewed motions of life 

 upon their being brought near to the fire. 



Mbfr. of thefe inftances are fo well attefted, that I conceive it 

 cannot be difputed by any one, that martins at leafr. appear occa- 

 nonally throughout the winter, whenever the weather is remark- 

 ably mild, and which agrees with what Sir William Hamilton 

 hath informed me, in relation to his fcarcely ever pa fling between 

 Naples and Pozzuoli without feeing fomeof thefe birds, when the 

 feafon at that time of the year was temperate. 



With regard to the third fpecies of fwallows,~the fand martin, 

 1 have never been able to collect a decifive inffance of their being 

 obferved at all during the winter, though poffibly fometimes not 

 diftinguifhed from the more common martin ; I will not there- 

 fore pretend to conjedlure what may be their peculiar lurking- 

 places, though I conceive that they undoubtedly have fuch. I 

 have however been negatively informed that they are not found in 

 the holes where they make their nelrs. This bird is commonly 

 fo diftant from the habitation of man* and is fo much in the dark, 

 that its habits are not eafily attended to. 



As for the fourth fpecies, called the Sw/fi*, which is well 

 known by its fuperior fize, and being almoft entirely black, 

 Linnaeus afierts, that it winters in the holes of churches \
