310 Postscript :—LeVerrier’s Report on 
peaks, the upper sides both tinted with rosy and violet light while the 
lower sides were brilliant white. Ido not doubt that the toothed form 
I assign to these peaks is real, which as it contrasted with that of the 
first appendages I have described, I verified with great care; moreover, 
in shifting the telescope, whose high power permitted a sight of only 
asmall part of the solar disc at one time, I saw a third peak a little 
higher, also tooth-formed, and resembling the two others in color an 
form, differing only in its larger dimensions. The remainder of the dise 
offered nothing remarkable, and on returning to the upper region I found 
the two first described clouds unchanged. As the moment of reappear 
ance of the Sun approached, and while waiting for the first rays, I made, 
during about 208, perhaps my most important observation. The margin 
of the disc which two minutes before was entirely white was now tinged 
to the height of seven or eight seconds was covered by a bed of rosy 
clouds, which appeared to gain in thickness as they emerged from behind

_LeVerrier goes on to state that the observation of his party authorize, 
his opinion, important modifications in the generally received notions F 
specting the physical constitution of the Sun. Arago in his notice of s¢ 
eclip ays, “ where exist the reddish flames with well defined outlines 
which during the total eclipse of the 8th of July, 1842, passed cons! ct 
ably beyond the outlines of the lunar disc? These flames were either 10 
the Moon, or in the Sun, or in our atmosphere ; unless, indeed, deny ad 
their actual existence, we regard them as an effect of light, for example 
as phenomena of diffraction.” ; 
The two last suppositions have found few partisans. Before soe Bb 
any hypothesis it is necessary to decide by observation a certain feature 
the phenomenon. During the eclipse, the disc of the moon moves across 
the disc of the Sun. But do these reddish clouds follow the moon ™
