Show New Metals in time Sun The announcement first made by Norman Lockyir that certain I bright lines In the solar spectrum indicated the presence In the sun of a hitherto unknown gas which he proposed to call helium In JS95 Ramsay Isolated this gas and we now know that Its density is about twice that of hydrogen hydro-gen and that the atomic weights of the two gases bear the same proportion But at the same tlmo says Cosmos abstracting an article In Prometheus Lockyor found in the spectrum of the corona other colored lines which he attributed at-tributed to the presence of another element to which he gave the name Voronlum Neither Ramsay nor any other chemist has yet been able to isolate this body Nevertheless nn Italian spectroscoplst has discovered the lines of coronium in the gases thrown out from the crater of Vesuvius Vesu-vius This has encouraged physicists to search for thin pearl of all the gascs present pust and future But this is not all at the same tlmo other physl clsls have had their attention directed to other Lines of the spectrum and announce an-nounce that there will next be discovered discov-ered two new metals that exist in the sun They have given to these elements ele-ments by anticipation tho mimes of aurorlum and nebulum Theposition occupied by those bodies in tho atmoo phone layers of time sun leads these scientists to think that they are lighter than hydrogen For chemlsts this discovery dis-covery will be a veritable revolution In fact It will destroy ProusOs hypo lliesiu which slates that ail the mole ctilar Aeights of bodies arc whole multiples mul-tiples of that of hydrogen However i S as no trace of cither aurorinm or nebu lum ban yet been found on time earth I the existence of these elementu is yet far from conclusive demonstration Literary DIgest |
