Upsal., Third Series, vi. Upsala, 1868. Taking as his starting-point the determination of wave-lengths of the principal Fraunhofer's Lines by Angström (Recherches sur le Spectre Solaire, par A. J. Angström. 1.-Spectre Normal du Soleil. Upsal. 1868), the author, by graphical interpolation, obtains, from Kirchhoff's and Angström's tables, the wave-lengths of the bright metallic lines. A large plate accompanies the Memoir, giving the lines and their wave-lengths of forty-five metals. The following twenty-three were examined in the metallic state:-K, Na, Mg, Al, Fe, Co, Ni, Zn, Cd, Pb, Tl, Bi, Cu, Hg, Ag, Au, Sn, Pt, Pd, Os, Sb, Te, In. The remaining twenty-two were examined as chlorides :-Li, Cs, Rb, Ba, Sr, Ca, Gl, Zr, Er, Y, Th, Mn, Cr, Ce, D, L, U, Ti, Wo, Mo, V, As. TYNDALL & FRANKLAND: On the Blue Band of the Lithium Spectrum.
