In this Table the correction for variation in the cistern is made in the entries. 
The maximum for the year was the greatest which had been observed from the commencement of my obser- 
vations ; it having followed the closing or westerly wind of a southeast storm which appeared two and a half 
days previous ; and for five days following the barometer did not fall below 30 inches. ‘I'he maximum of this 
atmospheric freshet was observed at Hudson, Ohio, by Prof. Loomis, on the 10th of November, at 11 A. M. 
Ogdensburgh, N. Y., by John H. Coffin, on the 11th, about 8 A. M.; at Montreal, L. C., by J. S. M’Cord, from 
9 A. M. till noon of the Llth; at New York, at 9 A. M.; at Providence, R. L., at 10 A. M. or later. In lat, 40° 34’, 
lon. 55° 35’, on the 14th, by Joseph C. Delano ; and on the 16th, by the steamer Liverpool, latitade and longitude 
unknown. At the close of December there was a still greater rise of the barometer, which followed a storm of 
ut moderate intensity, and reached its maximum on the first of January, 1839. 
The greatest fall of the barometer in 1838, was on the 16th of Hebruary, at 6 P. M., under the veering of a 
N. E. storm to W. N. W. The wind during the greater part of the 16th hung at N., the barometer falling with 
a steady fall of frozen rain drops or small hail, while the thermometer was 9° to 11° below the freezing point ; 
showing, as I think, the presence of a warmer stratum or current of wind in the region of clouds. When the 
wind had veered to N. W. the barometer commenced rising.
