TO THE EDITOR 



I 



Sir — Annexed you have some meteorological observations, made 

 by myself at this place during the past year, which might prove of in- 

 terest to some of your numerous readers, should they be deemed 







worthy of a place in your valuable Journal. The observations upon 

 the weather, were carefully made, and the thermometer, an excel- 

 lent instrument of Doliand's, was placed in a situation where it com- 

 municated freely with the external air. 



After seeing, in your July No. of last year, a description of Mr. 

 DeWitt's nine inch Conical Rain Gage, I sent to New York, hoping 

 to obtain the instrument, but it was not to be found ; you will there- 

 fore see that my observations are incomplete, in an important point. 



I remain, Sir, with high respect, your obi. servt. 



A. Mallory.
