Of the many experiments concerned with the unilateral conductivity of the so-called crystal rectifiers very few have had to do with the effect of gases. The experiments described in this paper show that an artificial rectifier can be produced through the action of hydrogen-sulphide upon zincite-copper contacts. Such contacts show little or no unilateral conductivity in vacuo but possess the property to a considerable degree in an atmosphere of hydrogen-sulphide.
