From the above sketch, hasty thongh it be, it is I think easy togather that the new view includes the facts much better than the oldone, and in truth demands phenomena, and simply and sufficientlyexplains them, which were stumbling blocks and paradoxes on theold one. This being so, then, it is permissible to consider it further, 9, Let us first suppose, to take the simplest case, that the sunwhen cold will be a solid mass of one pure element, , that the evo-lution brought about by reduction of temperatures shall be alongone line only. Let us take iron as the final product. Then thesuns atmosphere on the new theory qtm this one element may herepresented as follows :—■ ¥iGt, Assume strata A—L. Then— (1.) The Fraunhofer spectrum will integrate for us the absorption-of all strata from A to L. (2.) The darkest lines of the Fraunhofer spectrum will be thoseabsorbed nearest the outside of the atmosphere. (3.) We shall rarely, if ever, see the darkest lines affected in prominences. 296 Mr. J. N. Lockyer. [Nov. 23« (4.) The germs of iron are distributed among the varions strataaccording to their heat-resisting properties, the most complex at L^the least complex at A. (5.) Whatever process of evolution he imagined, as the temperatureruns down from A to L, whether A, 2A, 4A; or A + B, 2[2(A + B)],or X + Y + Z, the formed material or final product is the work of thesuccessive associations rendered possible by the gradually loweringtemperature of the successive strata, and can therefore only exist at L. 10. Now at this point a very important consideration comes was stated (in 6) while discus
