Further Experiments on Radium and Copper.

§ 99. A little later Madame Curie and Mademoiselle Gleditsch[123] repeated Cameron and Ramsay’s experiments on copper salts, using, however, platinum apparatus. They failed to detect lithium after the action of the emanation, and think that Cameron and Ramsay’s results may be due to the glass vessels employed. Dr. Perman[124] has investigated the direct action of the emanation on copper and gold, and has failed to detect any trace of lithium. The transmutation of copper into lithium, therefore, must be regarded as unproved, but further research is necessary before any conclusive statements can be made on the subject.
