The above results were deduced from three daily observations, made at sunrise, 1 p. 

 M. and 9 in the evening, by the Author. The location is in latitude 44° 29' N. and lon- 

 gitude 73° ir W., and is ojie mile eastward from the shore of Lake Champlain, and 

 elevated 256 feet above the lake, or 346 above the ocean. 



EXTREMES OF TEMPERATURE. 



Greatest and Least Heat in the Shade, and the Hottest and Coldest Day in each year 

 since 1837 — 15 years. 



By the above statement it will be seen, that, during the last fifteen years, the range of 

 the Thermometer has been from 100° above to 25° below zero, equal to 125°; and that 

 the warmest day was the 13th of July, 1849, and the coldest day, the 29th of January, 

 1844, and that the difference between the mean temperature of those two days was 100|°.
