An instrument is described with which cloud‐droplet samples can be taken from an aircraft by exposing momentarily glass rods coated with magnesium oxide. Exposures can be repeated about every three seconds. (i.e., about every 200 m). The spectra found in a traverse through a cumulus are shown. Features of the distribution of spectra can be determined which could not readily be found by methods which average over some distance, or by sampling methods not capable of being repeated so often. The samples are too widely spaced, however, to yield a coherent sequence of spectra across a cumulus.
