louthcrly winds, which convey their heat to a confiderable diflance 

 before they are cooled. 



But in latitudes between 55° and 36° a degree of cold far 

 fuperior to the aftronomical has often been obferved, and parti- 

 cularly of late, and in countries not very diftant, or even border- 

 ing on the Atlantic. Thefe extraordinary feafons may be attri- 

 buted partly to the abfence of the fuperior effluence or its refri- 

 geration in communicating with air replete with vapours, and 

 partly to the prevalence of eaft north-eaft winds which proceed 

 from the interior and coldeft parts of our continent, and hence 

 the cold of the year 1776, fo well defcribed by Van Swinden, 

 fecms rather to have followed the order of the longitudes than 

 , of the latitudes. Wargentin, ecretary to the- Royal Academy of 

 Stockholm, informs him that the cold obferved that winter in 

 Stockholm was not at all extraordinary, and expreffes his furprifc 

 that it fhould have been fo rigorous in Germany,France and England. 

 Mem. Paris, 1776, p 129. Nay it appears that the north-eaft 

 wind Vvhich raged fo furioufly in Holland and at Montmorenci, 

 latitude 49", on the 27th (See Van Swinden, p. 40) had not been 

 at Peterfburgh on the i8th, nor any day after; for a perfed calm 

 reigned on that day, and the high winds of the remainder of the 

 month were from the north-weft> Ad. Petropol. p. 382. It is 

 therefore 'probable that this wind proceeded obliquely from the
