Pagina 199 - But for those first affections, Those shadowy recollections, Which, be they what they may, Are yet the fountain-light of all our day, Are yet a master light of all our seeing; Uphold us, cherish, and have power to make Our noisy years seem moments in the being Of the eternal silence...
Pagina 497 - The day broke beautifully clear, and having crossed a deep valley between the hills, we toiled up the opposite slope. I hurried to the summit. The glory of our prize burst suddenly upon me ! There, like a sea of quicksilver, lay far beneath the grand expanse of water — a boundless sea horizon on the south and south-west, glittering in the noonday sun ; and on the west, at fifty or sixty miles...
Pagina 7 - Remove for a single summer night the aqueous vapour from the air which overspreads this country, and you would assuredly destroy every plant capable of being destroyed by a freezing temperature. The warmth of our fields and gardens would pour itself unrequited into space, and the sun would rise upon an island held fast in the iron grip of frost.
Pagina 197 - ... these the periods, for the most part, of greatest interest to mankind, the history of which may be so written that the actors shall reveal their characters in their own words ; where mind can be seen matched against mind, and the great passions of the epoch not simply be described as existing, but be exhibited at their white heat in the souls and hearts possessed by them.
Pagina 157 - Arranged to meet the requirements of the Syllabus of the Science and Art Department of the Committee of Council on Education, South Kensington.
Pagina 198 - But for those obstinate questionings Of sense and outward things, Fallings from us, vanishings; Blank misgivings of a creature Moving about in worlds not realized...
Pagina 175 - Beyond the second ridge a talus slopes gradually down northwards to the general level of the lunar surface, the whole presenting an appearance reminding the observer of the concentric moraines of the Rhone glacier. These ridges are visible for the whole period during which that portion of the moon's surface is illuminated ; but it is only about the third day after the first quarter, and at the corresponding phase of the waning moon, when the sun's rays, falling nearly horizontally, throw the details...
Pagina 608 - ... shooting arrows at him from both sides ; while the Death you see in the draught will seem, from an opening between hills in relievo, to have found admission by a shorter way, and prevented Time, at a distance...
Pagina 234 - ... water. While, however, a layer of the bisulphide of carbon 0-07 of an inch, in thickness transmits 72 per cent, of the incident radiation, and while every other liquid examined transmits more or less of the heat, a layer of water of the above thickness is entirely opaque to the radiation from the flame. Thus we establish accord between the periods of the molecules of cold water and those of aqueous vapour at a temperature of 3259° C.
Pagina 193 - First, it is a voice forever sounding across the centuries the laws of right and wrong. Opinions alter, manners change, creeds rise and fall, but the moral law is written on the tablets of eternity. For every false word or unrighteous deed, for cruelty and oppression, for lust or vanity, the price has to be paid at last ; not always by the chief offenders, but paid by some one. Justice and truth alone endure and live. Injustice and falsehood may be long-lived, but doomsday comes at last to them,...
