• The object of this investigation is to measure the electron densities of the plasmas obtained by passing condensed discharge through Geisler tubes (the inner diameter of the capillary being about 1mm) containing hydrogen of 5 mmHg pressure and helium of 7 mmHg pressure. The electron densities were determined using Inglis-Teller's formula in the Balmer series of hydrogen, and in the 2^1P_1-n^1S_0 and 2^1P_1-n^1D_2 series of helium. In the present examples the mean electron densities were n_H=2.4×10^<16>per cm^3 and n_<He>=1.0×10^<16>per cm^3.
