COMPARISON OF SPECTRA OF LIMB AND CENTER OF SUN 303 A second important distinction between the spectrum of thelimb and the center lies in the changes in the relative intensities ofthe lines. In general, as the brief tables based upon a preliminaryexamination of several regions indicate, these changes of line intensitycorrespond closely with those observed in the case of other words, lines that are strengthened in sun-spots are usuallystrengthened, in much smaller degree, near the suns limb.

Further-more, lines which are weakened in sun-spots are usually weakenedat the limb. Indeed, this latter effect seems to be relatively moremarked than the effect of strengthening throughout the whole rangeof the spectrum. Some important exceptions have been noted, andothers will no doubt appear in a more complete examination of thephotographs. Nevertheless, the resemblance in this particular ofthe spectrum of the limb to that of sun-spots is very marked, especiallyin the less refrangib
