The entire range of the barometer for the seven years, is 1:719, 
from 27-841 to 29:560: The range of the barometer at Hudson 
is only three quarters what it is at the level of. the sea in the 
same latitude ; that is, the barometric wave is reduced one quar- 
ter at the elevation of 1100 feet. It may hence be inferred that 
the great fluctuations of the barometer are confined to the lower 
regions of the atmosphere. 
Fluctuations of the barometer, exceeding ‘7 inch within 24 
hours.
