Abstract
IN a previous communication (NATURE, August 1, p. 170) I gave a preliminary account of the study of the band fluorescence of cadmium vapour. In the further investigations leading to the results presented, special care has been given to the removal of possible impurities in cadmium vapour. In order to remove completely the gases adsorbed by the walls of the quartz bulbs in use, the bulb, joined to the pumps, was heated in an electric furnace to about 900° C. for several days. The use of gas burners for heating the bulbs is not advisable, as at high temperatures the gases of the flame, first of all hydrogen, pass through the quartz wall and undoubtedly are occluded in it. Then, the bulbs being strongly heated when used, the gases may be liberated from the walls and pollute the vapour in question.
