Abstract
THESE two elements are among the few from which positively charged atoms have not been obtained by means of volatile compounds introduced into the electrical discharge or by means of anode rays. In a letter in NATURE1, the possibility of using the ions from a high-frequency spark was pointed out. With the mass-spectrograph [recently described in NATURE2] it was found that palladium consists of six isotopes with atomic masses 102, 104, 105, 106, 108, 110. They could be compared with doubly-charged platinum and gold atoms which were present as a slight impurity. The four middle components are about equally strong ; the one at 110 is weaker, and the lightest at 102 is the faintest.
