Abstract
THE accurate determination of composition is an important part of investigations into the upper atmosphere. Until now, the only method has consisted of sending up an evacuated vessel incorporating a device which opens a valve at the appropriate height and later closes it. This method has the disadvantage that vessels of practicable dimensions do not contain much gas, even at atmospheric pressure, and their exterior surfaces are bound to adsorb comparable or even larger amounts; of course, the method becomes still less satisfactory at the high altitudes which are now of interest.
