English: Diagram of the structure of a glow discharge, showing the names of the different glowing regions in the gas and graphs showing how the potential (V), electric field (E), charge density (n), and current density vary along the tube. The current density graph shows current due to electrons (j−) and positive ions (j+) separately. Similarly the charge density graph shows the density of the electrons (n−) and ions (n+) on opposite sides of the axis. VC and VA are, repectively, the "cathode fall" and "anode fall", the voltage drop at the electrodes.
Русский: Структура тлеющего разряда с различными светящимися областями в газе и графики, показывающие, как потенциал () электрического поля (), плотность заряда () и плотность тока изменяются вдоль разрядной трубки. На графике плотности тока отдельно показан ток, обусловленный электронами () и положительными ионами (). График плотности заряда показывает плотность электронов () и ионов () вдоль трубки. и – соответственно "катодное падение" и "анодное падение" – падение напряжения на электродах.

The Loeb book would have the copyright renewed in 1967. Online page scans of the Catalog of Copyright Entries, published by the US Copyright Office can be found at The Online Book Page. Search of the Renewals for Periodicals for 1966, 1967, and 1968 show no renewal entries for Loeb's book. Therefore the work's copyright was not renewed and it is in the public domain.
