IN some of the preliminary reports of the observations made during the last eclipse, undue importance appears to have been attached to the supposed absence of the Fraunhofer lines from the spectrum of the corona. Mr. Newall, for instance (Roy. Soc. Proc., vol. lxvii. p. 365), says, “it is difficult to reconcile the marked polarisation (of the coronal light) evidenced in this investigation with the absence of Fraunhofer lines in the spectrum of the corona.” Mr. Abbot, whose bolometric observations appear to him to indicate that the corona does not reflect much solar light, states that “additional evidence against the theory of reflecting particles is found in the Indian eclipse spectroscopic results of Campbell, who found a continuous spectrum from the inner corona with total absence of dark lines” (Astrophys. Journ., vol. xii. p. 75).
