Summary The arc spectrum of Bismuth has been investigated in the heavy arc and under-water spark, and the lines remeasured between λ 1900 and λ 3550. A discussion of the structure of the spectrum of Bismuth from the standpoint of the theories of complicated spectra is given. It is shown that in Bismuth, owing to its large atomic number, terms arising from the same level are separated by widely different values, and this renders the interpretation of the spectrum rather difficult. A large number of new lines has been obtained and a number of important lines has been carefully remeasured. The new lines include some predicted by Thorsen.
