Seite 57 - ... especially the south-east — were the high state of the barometer throughout the whole of the period, except a portion of August ; the high temperature in July, August, and September ; the great amount of sunshine ; and the deficiency of rainfall. Over the south-eastern portion of England more than 900 hours of bright sunshine were recorded during the four months June to September ; while at a few stations in the extreme south and on the east coast over 1000 hours were recorded. The sunshine...
Seite 63 - The intense lustre of its illuminated part dazzles the sight, and exaggerates every imperfection of the telescope; yet we see clearly that its surface is not mottled over with permanent spots like the Moon; we notice in it neither mountains nor shadows, but a uniform brightness, in which sometimes we may indeed fancy, or perhaps more than fancy, brighter or obscurer portions, but can seldom or never rest fully satisfied of the fact.
Seite 63 - The most natural conclusion, from the very rare appearance and want of permanence in the spots, is, that we do not see, as in the Moon, the real surface of these planets, but only their atmospheres, much loaded with clouds, and which may serve to mitigate the otherwise intense glare of their sunshine.

Seite 66 - Webb points out to be obvious enough. A very sensitive eye, which would detect the spots more readily, would be more easily overpowered by the light of a brilliant star, so as to miss a very minute one in its neighbourhood.
Seite 58 - September i and 2 differences of 25° were observed between tbe readings of the dry and wet bulb thermometers, and relative humidities below 30 per cent, were recorded at many inland places.

Seite 57 - Observatory, Greenwich, during the four months June to September. The chief feature which strikes one on looking at this diagram is the high state of the barometer throughout the whole of the period, except during a portion of August. The temperature was above the average in July, August, and September — the most remarkable point being the great heat at the end of August and the beginning of September. The sunshine was very abundant, the number of bright days being most marked. The rainfall throughout...
