THE EFFECTS OF RADIATIONS ON BIOLOGICAL SYSTEMS : III. THE EFFECT OF ULTRAVIOLET LIGHT ON THE RESPIRATION OF DROSOPHILA LARVAE AND THE DURATION OF THEIR PREPUPAL PERIOD.
1. Although ultraviolet irradiation of larvae did not prolong the larval stage as is the case with x-rays, the immediate effects on respiratory rates are strikingly similar. 2. Effects of irradiation at different ages were observed and also effects of successive irradiations with remarkable agreement in comparable lots.
