To quickly assess the difficulty of the text, read a short excerpt:
The salts give out the lines of the alkali ; for example, Li Cl give out the red lithium line and sodium salts the D line. It is remarkable that the lines due to the metal are more easily excited in the salts than in the metal itself. Thus if the liquid alloy of sodium and potassium is bombarded by positive rays the specks of oxide on the surface glow brightly with the sodium light while the clean surface remains quite dark. Some observers have noticed what seems a similar effect with hydrogen,... viz. That the hydrogen lines are more easily excited in water vapour than in pure hydrogen. The fact that in the positive ray photographs, the parabolas corresponding to a certain type of ray, for example the carbon or oxygen atom with two charges, is more easily developed from compounds than from the molecules of the gases themselves, is probably connected with this effect. The production of spectra by bombardment with cathode rays has been investigated by Gyllenskold ("Ark. F. Math. 170 RA YS OF POSITIVE ELECTRICITY Ast.
