It is shown that the use of Bohm's criterion for the formation of a wall sheath by Hoh in an attempt to explain the marked change in behavior of the positive colunm of a glow discharge in a magnetic field as the magnetic induction is increased beyond a critical value is not justified. A review of the Bohm derivation of the potential distribution within a sheath is presented. It was concluded that the nonsatisfaction of Bohm's criterion should be considered nore as a warning against a breakdown of the theoretical model than as a condition in the system itself. (M.C.G.)
