Observations made at Buffalo, X. Y. 



These places are but ninety miles apart, yet such is the in- 

 fluence of the lake winds on the temperature of the latter position, 

 that it denotes an atmospheric depression of temperature of 5°. 

 At the same time, the range between the maximum and minimum 

 was exactly the same. 



Observations made at Detroit. 



The average temperature of this place for May is denoted to 

 be some five or six degrees higher while the wind remained at 

 N. E., but on its changing to S. W. (on the 21st), the temperature 

 ran up four degrees at once. As soon as it changed to IST. W. (on 

 the 24th), the thermometer fell from its range on the 21st four- 

 teen degrees. 



The uncommon beauty and serenity of the Michigan autumns, 

 and the mildness of its winters, have often been the subject of 

 remark. By a diary of the weather kept by a gentleman in 

 Detroit, in the summer and fall of 1816, from the 24th of July to 

 the 22d of October, making eighty-nine days, it appears that 



57 were fair, 



12 cloudy, and 



20 showery and rainy.
