...short years ago mathematical builders of the universe got along with two fundamental particles, the proton and the electron. The proton was the nucleus of the simplest atom, hydrogen. It had a charge of positive electricity and its mass was .0000000000000000000000166 gram. The electron, which in the hydrogen atom throbbed alone around the nuclear proton, had a negative charge matching the proton's positive charge and its mass was 1,847 times less than that of the other particle. The more complex atoms of other elements were constructed from various combinations of electrons and protons...

...stated that American science has increased a great deal in recent years, while most of the eminent German scientists had left that country. Among the greatest recent discoveries in this country are the laboratory production of heavy hydrogen and the positive electron...
...Suits passed a brilliant arc between two electrodes of a welding torch in an atmosphere of hydrogen. This was magnified and projected in color on a frosted glass screen. The engineers saw the images of the electrodes three inches apart, with the broad, vivid flow of the arc two inches wide. Then Dr. Suits produced an arc in an atmosphere of nitrogen. The arc band was pale, thin. But when he stepped up the nitrogen pressure to 1,200 Ib. per sq. in., the arc thickened and brightened until it was indistinguishable from that produced in hydrogen...
