xp planation,” which the writer remarks he had “ not hap-

probably others will consider it proper to preserve, in this 
place, the following more extended observations of Dr. 
wight, who was a careful observer of rests phenomena, 
and particularly attentive to meteorology. 
President Dwight remarks in the first lice that the 
extremes of our temperature a particularly of cold, are 
much greater than in the corresponding latitudes of "Eu- 
rope ; that the changes are more sudden and considerable, 
that a change of thirty degrees in twenty-four hours some- 
ess occurs, and that 1 in one instance he had known it te

“The winds, which generate the peculiar cold of this

a source, very different from all those, ‘which have been 
specified ; and descend, in most cases, from the superior

regions of, the atmosphere. My reasons for this opinion I 
will now proceed to state. 
It is well known to men of information, that in the hie.

and Eastward, of the meridian. The atmosphere ute
