The preceding table contains the mean or average results 

 of a series of hourly observations continued for twenty- 

 years, viz., from 1841 to 1861. The cistern of the Baro-

 appears upon inspection of the column of atmospheric pres- 

 sure, that after being duly corrected to the usual standard 

 temperature of 32° Fahrenheit, the Barometer reads highest
