Abstract
THE LINE SPECTRUM OF COPPER.—Some exceedingly interesting results have been obtained by Mr. A. S. King at Bonn during a detailed study of the line spectrum of copper under many various conditions of arc and spark discharges. Mr. King suggests that an accurate knowledge of the conditions which produce spectral changes can only be obtained by the detailed study of each element under every possible condition of temperature, vapour pressure, and electrical excitation, and to this end he has commenced with the line spectrum of copper.
