observations have been made over temperatures between 900" and 1300" C. The initial conductance is found to obey Ohm's law; its temperature dependence is of the usual exponential form with an activation energy of 1.1 volt. Optica1 absorption measurements show an absorption maximum at 4000 A.U. Assum
