A few lines in the visual region of the oxy-hydrogen fame spectrum of iron were recorded in 1887 by Sir Norman Lockyer. This list was supplemented in 1893 by a map showing all the then known flame lines of iron in the photographic region. In the following year Hartley published his researches on "Flame Spectra at High Temperature," including a list of lines in the spectruin obtained by heating compounds of iron in the oxy-hydrogen flame. This list extends from λ5927·7 to λ 3021·1. Flame spectra of iron have been studied in great detail by de Watteville, working alone or in collaboration with Hemsalech. In particular they have published an extensive list of wave-lengths and intensities of lines observed in the oxy-hydrogen flame fed by a current of oxygen previously passed through a globe in which an electric spark was being maintained between iron poles.
