1000 feet, as shown in the preceding Table, with the approximate amount 
of the disturbance caused by the warm currents of air, were read. 
August 20.—The clouds were not passed; at heights above 3500 feet the 
balloon ascended and descended repeatedly. In this ascent there was no 
marked interruption to the regular decrease of temperature with increase of 
height. |
