1. The brush discharges from a counting point have been examined with the microscope.
2. Magnetic fields have been shown not to affect counting under certain conditions.
3. The function of the series resistance has been further studied.
4. An approximate measurement has been made of the mechanical reaction on the electrodes.
5. An attempt has been made to detect hysteresis in the discharge, with negative results.
6. An effect of intense ionization has been noted.
