On the Climate of the 



These places in the former region, are Albany, (New- York,) Cam- 

 bridge, (Mass.) New- York, Philadelphia, and Williamsburgh, 

 (Virginia) ; and are included in a range of about six degrees of 

 longitude ; in the latter region, Cincinnati, (Ohio,) St. Louis, 

 (iMissouri,) and Council Bluff. I shall now present a tabular view 

 of their latitudes and mean temperatures. 



1. On the Atlantic Coast. 



2. In the Valley of the Mississippi. 



From this table it appears that the mean temperature of Cincin- 

 nati, is only four-tenths greater than that of Philadelphia, although 

 the former is 50' south of the latter. The difference here is prob- 

 ably not greater than it would be east of the Alleghanies. The 

 comparison between the climate of these two places, has been so 

 ably drawn by Dr. Drake, in his Picture of Cincinnati, that I shall 

 do no more than state that this author gives it as his opinion—the 

 result of numerous and faithful observations— that the climate of 

 Cincinnati is not warmer than that of a corresponding parallel on
