Abstract
RECENTLY, reports have appeared in the press of experiments demonstrating the existence of a dermal sensitivity to intensities and wave-lengths of visible light. Many of the experiments do not appear to have precluded thermal effects, and B. Konstantinov has suggested1 that the results may be explained by the perception of reflected infra-red radiation emitted by the hand. In the experiment recorded here these effects have been reduced, and college-age subjects have been required to discriminate between black and white.
