One curious feature in the oscillations of the 
Barometer cannot fail to be noticed by every 
attentive observer. If the average height of the 
Barometer for any month be supposed thirty 
inches, and the highest extreme 30.5 inches, then 
the lowest extreme will mostly be about twenty- 
nine inches, or twice as far below the mean as the 
high extreme is above it.
