Abstract

During the past two years, there has been considerable discussion on the question of the emission of ultra-violet light by cod liver oil. Our experiments have confirmed the opinion that no radiations are emitted which can penetrate plates of fused quartz one millimeter in thickness. However, an image is produced on a photographic film placed directly above the oil, an effect which is attributed to a direct chemical action. We have also found that other oils which would not produce images on the photographic film can be activated by ultra-violet light so that they act like cod liver oil. Different oils can be activated in different degrees, which is similar to the results obtained with the production of anitirachitic properties in them by ultra-violet light.
