Schemer thinks possible merely a photographic effect. M. Janssen considers that the photospheric cloudlets change their shape and character with the progress of the sun-spot period; but this is as yet uncertain.
In 1842 they attracted great attention, and were then compared to Alpine snow-peaks reddened by the evening sun. That these prominences are flaming gas, and principally hydrogen gas, was first proved by M. Janssen during an eclipse observed in India, on the 18th of August, 1868. But the prominences may be rendered visible in sunshine; and for a reason easily understood.
About this time the telescope was invented by Janssen, a spectacle-maker of Middleburgh, in Zealand. Hearing of it, Galileo immediately constructed his first very imperfect instrument, which magnified only three times.
Here General Janssen commanded in person, with General Jumel, a Frenchman, under him, with an army of 13,000 men. Notwithstanding this, the forts were stormed and taken, and the greater number of the officers captured. The commander-in-chief, with General Jumel, escaped the latter, as I have mentioned, to fall very soon afterwards into our hands.
In France the splendid sun-pictures obtained by Dr. Janssen at the Physical Observatory of Meudon have thrown into the shade all other attempts at a photographic study of the most delicate features of the solar surface. Dr.
I said I fancied such a morning as this was not very mild for people that had no fires, and this brought me back again to Janssen and Marina, by way of the coke-cart. The thought of them rapt me so far from the druggist that I listened to his answer with a glazing eye, and did not know what he said.
Janssen, for instance, felt compelled, by the survival of unwise doubts, to devote some of the precious minutes of obscurity at Caroline Island to confirming what, in his own persuasion, needed no confirmation that is, the presence of reflected Fraunhofer lines in the spectrum of the corona.
It embraces the whole material and spiritual natures of human society with such power and completeness that verily no room is left for any other life than that decreed by its dogmas. 'The aim of the Church, says Janssen, 'in view of the tremendous agencies through which it worked, in view of the dominion which it really exercised, cannot have the impression of its greatness effaced by the unfortunate fact that all was not accomplished that had been planned. The fact that tyranny may have been exercised by some provincial governor in an outlying island of the Roman Empire cannot close our eyes to the benefits to be derived from a study of the code of Justinian; nor can a remembrance of the manner in which English law is administered in Ireland in times of excitement, blind us to the political lessons to be learned from an examination of the British constitution.
About midway between its extremities, this great gorge is crossed by a wall of rock, like a narrow bridge. JANSSEN. An immense irregular enclosure, reminding one of the very similar area, bordered by Walter, Lexell, Hell, &c., in the third quadrant. It extends about 150 miles from E. to W., and more than 100 from N. to S., its limits on the N. being rather indefinite.
An enthusiastic astronomer, Janssen, was commissioned by the Academy of Sciences to attend and make observations of this eclipse. But M. Janssen was in Paris, as were also his instruments, and the eclipse track lay nearly a thousand miles away.
