To quickly assess the difficulty of the text, read a short excerpt:
As the analysis of the solar and laboratory (spark and arc) intensities of the vanadium and titanium lines has not thrown much light on the conditions in sun-spot vapours and the absorbing vapours of the lower-type stars, it has not been thought worth while to give a similar analysis for other elements such as chromium and iron, some of the lines of which, although affected, are not so conspicuously affected as the vanadium or titanium lines. BEHAVIOUR OF ENHANCED LINES IN PASSING FROM THE SOLA...R SPECTRUM TO THAT OF a ORIONIS. It has been shown by Professor Fowler* that the enhanced lines of iron and titanium, which form such a prominent feature of the spectra of such stars as * Monthly Notices, Vol. 66, p. 361, 1906. . A 19879 28 SOLAR PHYSICS COMMITTEE. a Cygni and Sirius, weaken in general in sun-spot spectra, as compared with their intensity in the Fraunhoferic spectrum. With the small dispersion of the Kensington two- prism spectra of the sun and a Orionis, the enhanced lines in general are not sufficiently isolated from other lines as to enable us to trace their behaviour in passing from the solar to the stellar spectrum.
