Abstract
On the Temperature of the Air at four feet, twenty-two feet, and fifty feet hight—j. Glaisher, F.R.S. In his opening remarks, Mr. Glaisher spoke of the erroneous opinions which were entertained previous to his balloon ascents with regard to temperature at different heights; it was supposed that the temperature of the air always decreased from the earth upwards, and followed some constant law; this was, however, found not to be the case; and in the Report to the British Association at Nottingham, in 1866, the conclusions were, “that the law of decrease of temperature with increase of elevation was variable throughout the day, and also in different seasons of the year; that at about sunset the temperature was sensibly the same up to 2,000 feet; and that at night (conjectures from the results of the observations taken in the only two night ascents) the temperature of the air increased from the earth upwards.” It was therefore evident that a very large number of ascents would have to be made to determine the real laws.
