Abstract
Using a hot carbon tube at about 1600°C as the absorption cell, the spectra of these elements have been studied in absorption from 6000 to 2000A. The vapor of tellurium was dissociated into atoms by a simple device and 4 absorption lines were found. Two new arc lines were measured. The same arrangement gave 8 bismuth absorption lines, 4 being new. These are exactly the lines to be expected from the work of Ruark, Foote, Mohler and Chenault. Four new arc lines were measured in the spectrum of a 75 ampere arc. Chromium was placed directly in the carbon tube and 3 triplets were absorbed. Nineteen copper lines were absorbed, 10 being from the normal state in agreement with Shenstone and McLennan and McLay and 9 new ones from excited states.
