Excerpt: ... CHAPTER VI. DURATION, INTENSITY, AND COLOUR OF PHOSPHORIC LIGHT IN MINERAL BODIES. The duration, the intensity, and the colour of phosphoric light produced by mineral substances, depend upon the nature of the phosphorescent body. I shall mention only a few examples of colour. The most general tint of light is that seen in the glow-worm and other phosphorescent animals, of which we shall speak hereafter; it is a greenishyellow light, at times approaching to whiteness. Some bodies however appear, during their phosphorescence, to emit light which differs a little from this as to its colour. Certain marbles and amber (succinum) give a phosphorescent light of a golden yellow; some specimens of fluor-spar, arseniate of lime, and chloride of calcium, emit a greenish light; other varieties of fluor-spar produce a bluish-violet radiation, and that which is called Chlorophane gives a green phosphorescence. Oriental garnet shines with a reddish phosphorescence, whilst Harmotome (a sort of zeolite) gives a greenish-yellow phosphorescence. Dolomite, Aragonite, and some specimens of diamond, shine with a brilliant, white, phosphoric light. In the same manner, the colour of a flame depends upon the nature of the body that burns. Thus, carburetted hydrogen and sodium burn with a yellow flame, oxide of carbone with a blue flame, potassium and cyanogen with a purple flame, etc. Pearsall, Brewster, Dessaignes, and Becquerel have studied this subject. It appears to me very evident that the same substance may slightly differ in the colour of its phosphorescence, according to the manner in which the latter is ,prepared or excited. Concerning colours and tints, we should, in general, be careful in admitting them too exclusively, for there are scarcely two persons who will entirely agr...
