and would, I am sure, well repay it. My time was but a few 
days (three and a half only available for the purpose); and I 
could of course only take a small part; but it may very fairly 
be taken as a sample of the whole, and there can, I think, be no 
Pi if 
sufficient moisture present for the Tt sight never 
to be forgotten to see in the splendid definition of the mountain 
air, the clear solar spectrum, and ; he aned, lime 
which I have called D 3 isawonder. At midday it is a fine thin 
line, and at sunset it is fully ten times darker. With regard to 
the line 8, which I have never seen in Sydney, I feel sure it 
16th the telescope was turned to the sun, and its edge and sur- 
face markings were beantifully seen, but not a spot was visible 
whose changes we could record. ere were many exclamations 
from the observers about fine definition, but we wante ts, 
and could not find even the facule which precede them; for 
once the sun was spotless. Several stars were observed in the 
sunlight with the object of adjusting the instrument, and the 
sky. There was no white halo round Jupiter forming a bright 
background ; and my notes are full of such remarks as (“ planet 
equalled. There was such an amount of detail that the eye 
searcely took it all in before the scene changed by the rotation 
of the planet. As to drawing it all, that was out of the question. 
Mr. Hirst and I both tried, and I am sure he will bear me out 
when I say that the drawings only show a fraction of what we saw.
