ME. WAEEEN DE LA EUE ON THE 
passed through the glass, and was therefore not reflected to the eye. I then, cautiously, 
but rather quickly, brought into action the silvered surface, and beheld with delis^ht 
that the luminosity of the prominence, which I will call A*, was so great that there 
could be very little doubt of our obtaining the much wished-for photographic pictures. 
I now watched carefully for the so-called Baily’s Beads, but no such phenomena pre- 
sented themselves, — at which, however, I felt no surprise, for I had always believed that 
they arose, in all probability, from the atmospheric disturbance of an image formed by 
a telescope wanting in perfect definition. The Dallmeyer I used was so perfect that I 
did not think I should see anything of the kind. 
To the east of the zenith, about 20°, a floating cloud, quite detached from the moon’s 
limb, and distant from it more than 0'-6, next attracted my attention. This cloud, which 
I will call C, appeared about 1'‘5 long, and was inclined about 50° or 60° to the moon’s 
limb. It had two curvatures, both convex on the edge most distant from the moon, and 
was decidedly of a rose tint, but of a much paler hue than the published accounts of 
previous eclipses had led me to expect. I compared the prominence carefully with my 
scale of tints, and found that it very nearly matched the colour marked c. It must 
therefore have been of a yellowish pink (approaching a salmon) ; for c on my chromatic 
scale was a mixture of carmine and cadmium yellow. This prominence (C) presented a 
great amount of detail, and reminded me of the aspect of a cirrus cloud glowing with 
the illumination of a setting sun. I should here remark that, in comparing my scale 
of colours with the luminous prominences, I depended on the general light of the 
heavens, and that I did not employ my lamp, which, I found, completely changed their 
appearance. 
The prominence A was generally more brilliant, and did not seem to me to he so pink 
as the detached cloud ; I could, moreover, detect a tinge of yellow in its brilliant light. 
It also showed considerable structure, appearing to consist of several streaks, curved 
inwards, while from the summit came two peach-coloured faint streamers, bending over 
in opposite directions downwards towards the moon’s limb. 
I paid most particular attention to the prominence A, because I knew from its posi- 
tion that it was critically placed for the observation of any change of position-angle in 
reference to the moon’s centre ; and I also remarked carefully the prominence C. and 
sketched all that I could make out by the most careful scrutiny. On comparing my 
drawings with the photographs, it will be perceived that a certain boomerang-like promi- 
nence in the photograph is wanting in my hand-drawings, and that there are also othei' 
prominences visible in the photograph which are not shown in the drawings. This is a 
curious circumstance, hereafter to be more particularly dwelt upon ; but it is right to 
mention it here, because it afibrds me the opportunity of saying that, at all events, as 
regards the boomerang, I am certain that it was not visible in the telescope ; for I observed 
so carefully in the neighbourhood of the floating cloud, that it is next to an impossibility 
that such an object could have escaped detection.
