The apparatus used consisted of a capillary vacuum tube closed with a plate of quartz under a pressure of less than 1 mm. of mercury, and a spectrograph containing two calcite prisms of 60° and two quartz lenses of 1.3 metres focal length. The latter produced a dispersion which, in the neighbourhood of N=42,189 ( 2370). gave separation of 0.005 mm. for a difference of 0.06 N.

The wave-lengths of the lines were obtained by reference to a spectrum of iron, using Kayser's fundamental Falues for the wave-lengths of the latier, and the authors state that in the individual values obtained for N the first six figures are correct.

In the results it is seen that, although the lines of the band may be separated into four series of doublets according to Deslandres's law, so that the difference of wavelengths in each series advances in arithmetical progression, yet the variations from the computed values
