Page 392 - Were a star quenched on high, For ages would its light, Still travelling downward from the sky, Shine on our mortal sight. So when a great man dies, For years beyond our ken The light he leaves behind him lies Upon the paths of men.
Page 608 - Thus, in this eight hours of a not very severe magnetic storm, as much work must have been done by the snn in sending magnetic waves out in all directions through space as he actually does in four months of his regular heat and light. This result, it seems to me, is absolutely conclusive against the supposition that terrestrial magnetic storms are due to magnetic action of the sun, or to any kind of dynamical action taking place within the sun, or in connection with hurricanes in his atmosphere,...
Page 519 - If I climb up into heaven, thou art there: if I go down to hell, thou art there also.
Page 394 - On the evening of the 29th of August, 1864, I directed the telescope for the first time to a planetary nebula in Draco. The reader may now be able to picture to himself to some extent the feeling of excited suspense, mingled with a degree of awe, with which, after a few moments of hesitation, I put my eye to the spectroscope. Was I not about to look into a secret place of creation ? I looked into the spectroscope.
Page 42 - The regions within which the eclipses of the Sun are visible are laid down on the accompanying charts, from which, by means of the dotted lines, the Greenwich...

Page 643 - May it not be that the effect of great mass on surface density, together with the working of Lane's law . . . will favor in such stars the coming in of a solar type of spectrum at a somewhat relative earlier time?
Page 309 - ... year. Mr. MILLS was the donor of the two Mills spectrographs used in connection with the 36-inch refracting telescope ; and the DO Mills Expedition from the Lick Observatory, University of California, located on the summit of Cerro San Cristobal, Santiago, Chile, is due solely to his generosity. Mr. MILLS was a member of the first Board of Trustees appointed by JAMES LICK to control the construction and equipment of the Lick Observatory, in which duty he gave freely of his time and mature judgment....
Page 393 - This news was to me like the coming upon a spring of water in a dry and thirsty land. Here at last presented itself the very order of work for which in an indefinite way I was looking — namely, to extend his novel methods of research upon the sun to the other heavenly bodies.
Page 393 - I felt as if I had it now in my power to lift a veil which had never before been lifted ; as if a key had been put into my hands which would unlock a door which had been regarded as for ever closed to man — the veil and door behind which lay the unknown mystery of the true nature of the heavenly bodies.
