WebThe negative ionisation from hot platinum in air is unaltered when hydrogen is allowed to diffuse out through the platinum. These results show that neither the negative nor the positive ionisations usually observed with hot platinum heated in air or oxygen are due to residual traces of absorbed hydrogen. Webway the negative leak from metallic calcium was compared with the negative leak from the same amount of metal in the form of oxide. The full account of the experiments and results is divided for convenience into the following sections:-(1) Description of the apparatus, &c. ; (2) Investigation of the negative leak from platinum;
