Glow in a stream of charged particles

The results of an experiment with a generator of a stream of charged drops are reported. The glow of subjects placed in the stream is observed. The volume of the glowing region reaches 20 cm${}^3$ at a current less than 20 $\mu$A through the object. Ideas are expressed concerning the connection between St$\mathrm{.}$Elmo’s fire and the observed glow.
