This table indicates the difference of climates, expressed by 
that of the meap temperature, and by the number of degrees, 
in latitude which it is necessary to go northward in Europe, in 
* The, differences under the column of latitudes, is the difference of the latitude 
of a place in Europe and a place in America, which have the same mean tempera- 
ture ; and the differences under the column of mean temperatures, is the difference^ 
of the mean temperatures of a place in Europe and a place in America, which 
have the same latitude. — Ed.
