Metal surfaces which have been bombarded with cathode rays and those which have not been so bombarded, react differentially toward chemical vapors. Surfaces which have been rayed through a stencil and developed in certain vapors, reveal the image of the stencil pattern. It was desired to protect the unrayed areas with an inactive and nonconducting coating. The rayed areas should then acquire a deposit when the specimen is electroplated. This was best accomplished by development in the absence of air, with ionized organic vapors. Attempts were also made to raise the surface of the rayed regions directly. Preliminary experiments indicate the development with metallic vapors, in the absence of air.
