But that strontium, which makes fireworks burn red, that boron, which volcanoes heave forth, that titanium, which makes war smoke screens, that vanadium, which hardens steel−that such metals of horrendous connotation were also in solution was a revelation made to U.S. householders only last week, from Cornell University. Drs. Jacob Papish and Norman C. Wright made the discoveries there with a spectroscope. The metallic contents are "small but definite...
When interviewed in his subterranean laboratory yesterday. Mr. Mulliken said that he had been started upon his research by an article published in 1915 by Dr. W. Jevons, a noted English scientist. In this article Jevons had described his observations of the band spectra of boron nitride; he had measured the heads of two systems of spectrum bands of boron nitride and located two subsidiary systems of bands and also extra bands apparently filling no system...
...reading this article, Dr. Mulliken, who has previously studied isotopes at the University of Chicago, began his experiments in Cambridge to prove that the unrelated spectrum bands were due to the isotopes of the boron atom...
...boron chloride employed by Dr. Mulliken is similar to that used by Professor G. P. Baxter '96 in his recent experiments to determine for the first time accurate atomic weight of boron...
