This samewonderful element hasbeen shown to be in allprobability the mate-rial which constitutesthose glowing solarclouds to whose kindlyradiation our very lifeowes its origin. In the ordinary in-candescent electriclamp, the brilliantlight is produced by aglowing filament ofcarbon. The power-ful current of elec-tricity experiences somuch resistance as itflows through thisbadly conducting sub-stance, that it raisesthe temperature of thecarbon wire so as tomake it dazzlinglywhite-hot. Indeed thecarbon is thus elevatedto a temperature far inexcess of that whichcould be obtained inany other way. Thereason why carbon isemployed in the elec-tric lamp, in prefer- t h e composition of comets. Carbon is not only intimately as- ence to any other substance, may
