"I am still in doubt whether it is a new element or merely an allotropic modification of the common element, cadmium. The plate which he used has a very peculiar property. When moonlight, or any other reflected light of the same composition falls on it, it acts on the ray much as the button of a Roentgen tube acts on a cathode ray. As the cathode ray is absorbed and an entirely new ray, the X-ray, is given off by the button, just so is the reflected moonlight absorbed and a new ray of ultra-violet given off. This is the ray which Von Beyer detected. I thought that I could catch traces of Von Beyer's lines in my spectroscope, and I think now that it is due to a trace of lunium in the cadmium plating of the barrels. Von Beyer could have easily made the same mistake. Von Beyer's work, together with Stokowsky's opens up an entirely new field of spectroscopic research. I would give a good deal to go over to Baden and go into the matter with Von Beyer and make some plans for the exploitation of the new field, but I'm afraid that my pocketbook wouldn't stand the trip." "I think that the United States owes you that trip, Dr. Bird," said the Chief Executive with a smile. "Make your plans to go as soon as you get your data together. I think that the Treasury will be able to take care of the expense without raising the income tax next year." +------------------------------------------------------+ | | | _IN THE NEXT ISSUE_ | | | | | | Murder Madness | | | | _Beginning an intensely Gripping, Four-Part Novel_ | | | | _By_ MURRAY LEINSTER | | | | | | The Atom Smasher | | | | _A Thrilling Adventure into Time and Space_ | | | | _By_ VICTOR ROUSSEAU | | | | | | Into the Ocean's Depths | | | | _A Sequel to_ "_From the Ocean's Depths_" | | | | _By_ SEWELL PEASLEE WRIGHT | | |
