Science and Invention (09:01) May 1921

Hugo Gernsback, editor

"Dr. Kilner was convinced that the human aura existed and his researches then were concerned mainly in trying to make it visible. He considered many different means and first thought that the forces were situated in the infra-red portion of the spectrum. This, however, did not prove to be the case and in 1908 he thought of certain dyes that might be of use. Finally, after many trials, his researches became fixt upon a certain coal tar dye dicyanin, and with this dye he obtained the best results."
