and 4384, the phase y, in the simple Rydberg formula being abo the limit being approximately that of the Diffuse Series of Parhelium, but the measurements of the wave-lengths of the lines are not sufficiently accurate to establish fully their series relations. A number of other lines have been observed, but an investigation with higher dispersion will be required for a full elucidation of the spectrum.]
