Excerpt from Luminosity and Temperature Previous work has been limited to portions of the general problem. There are some good experimental determinations of the amount of light (monochromatic and total) emitted by bodies at known temperatures, but no one appears to have attacked the general problem directly.

Excerpt from Luminous Radiation From a Black Body and the Mechanical Equivalent of Light The visibility curve of the average eye gives a 'value for the least mechanical equivalent of r lumen 0001627 watt of luminous flux of maximum luminous efficiency. The i two determinations of the least mechanical equivalent of light made by Ives, Cob lentz, and Kingsbury are corrected. The values obtained by their two methods of measurement, using 61 observers, are in exact agreement, giving 1 lumen watt.

Excerpt from The Waidner-Burgess Standard of Light Fleury 11 and Chappius 12 have been working With a black body, the temperature of which is defined by the ratlo (n of its radiation (at wave length M) to that of a black body held at the gold point. The ratio is measured by means of a spectrophotometer and a sector disk. For a radiator matching in color the carbon filament standard lamps N lies between 450 and 470. The precision islestimated at better than per cent. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
