PART I 



A LMOST from the first discovery of North America, 



A 



it has been observed/ that the extremes of heat and 



cold are much greater on this side the Atlantick Ocean, 

 than they are in Europe, under the same parallel of latitude. 

 But the quantity of this difference has not hitherto, so far as 

 I am acquainted, been an object of much attention, or been 



determined with any degree of 



A valuable work 



annually published for some years past, by a Meteorological 

 Society at Manheim in Germany, entitled Ephcmcridcs 3Iete- 

 orohgicm Palcdinw, affords »j^ata for determining this pomt 

 more precisely; as it contains more numerous and more ac- 

 curate observations, than any other jjublication extant. 



I have therefore, from this collection, formed a table of 

 the greatest heat and greatest cold, and of the mean of the 

 greatest heat and cold, for a course of years, of twenty dif- 

 ferent cities in Europe j the southernmost of which is 

 Rome, in lat. 41° 63', a few minutes southward of Boston; 

 and the northernmost, Stockholm, the cajoital of Sweden, 

 in lat. 59° 20', comprehending an extent of upwards of 17 

 of latitude ; and from Rochelle, on the western coast of 

 France, to Buda, the capital of Hungary, comprehending 

 20° of longitude; which takes in all the middle region of 



I 



Europe.
