The greater part of this investigation of the spectrum of scandium under different experimental conditions has been based on purified scandia, generously placed at the author’s disposal by Sir William Crookes. The principal results are as follows:— 1. The arc spectrum of scandium consists of two distinct sets of lines, which behave very differently in solar spectra. Each set includes both strong and faint lines. 2. Lines belonging to one set correspond with the enhanced lines of other elements, notwithstanding that they appear strongly in the ordinary are spectrum— (a ) These lines are very feeble or missing from the arc-flame spectrum, and are strengthened in passing to the arc, the arc in hydrogen, or the spark.
