TOTAL SOLAE ECLIPSE OF JULY 18, 1860. 
369 
In the eastern quadrant (in reference to the zenith) a long line of prominences, 
extending over 70° on the moon’s limb, was visible at the commencement of the totality, 
but before the end of totahty it was covered by the lunar disk. This streak (which 
I call I) terminated in a hook, about 1''5 high, bent upwards, and was much indented 
on the concave side, where it was in contact with the moon’s edge. It was extremely 
brilliant, and, although it presented in parts a pink colour, was not uniformly so coloured, 
but to my eye had here and there a considerable admixture of yellowish white. In the 
first photograph of the totality is depicted a curious branching prominence, not unlike 
the fallen stump of a tree, which I did not observe, and therefore did not record in the 
sketches. I do not state so positively that this prominence was not visible, for this 
reason, that I did not pay such special attention to that part of the field, my eye being 
directed more particularly to the prominences A and C ; but I have a strong impression 
that it was not visible. Just about the part where this would be, the corona appeared 
to me, in the telescope, to be particularly bright ; but, besides a mere sheet of brilliant 
light, I saw nothing to delineate. 
About half a minute after the commencement of totality, the progress of the moon 
uncovered, in the western quadrant (in reference to the zenith), a small peak, like that 
of a mountain, which I will call E. As the eclipse progressed, this prominence became 
more and more uncovered, and another smaller peak appeared, the whole contour 
reminding me somewhat of the hull and masts of a ship in full sail. Just before the 
reappearance of the sun this prominence reached apparently about I'’5 beyond the 
moon’s limb. 
Extending from the southern base of this prominence, there came into view, about a 
minute before the end of totality, a long streak of prominences much indented and irre- 
gular on the concave side. This streak extended over fully 50° on the moon’s limb, 
when it had been fully uncovered by her onward course. It was pretty generally of a 
decided rose tint. Just previously to the reappearance of the sun, I remarked a sort of 
carmine glow near that part of the moon’s limb where the crescent of the sun was first 
re-formed. 
Plate VI. is a most exact fac-simile of the two drawings, black representing white, 
which I made during the totality, and it is desirable that I should make a few remarks 
about them. 
Figure I was begun, as nearly as I can recollect, about thirty seconds after the com- 
mencement of totality. As a preliminary step, the moon’s disk was brought exactly within 
the tangential square, and the position of the prominence A, in respect of the line D, 
was noted first of all, and at once marked down on the left-hand diagram ; the hook I 
was then referred to the line B, and the mountain E to the line D, the latter being 
registered with great care. The floating cloud and the other prominences were then 
filled in, possibly not quite so carefully. The details were next drawn in, black repre- 
senting white, and the first diagram was completed as rapidly as possible, yet as faith- 
fully as the short time at command would permit. I was aware, whilst so occupied,
