Page 157 - It may, therefore, be, that nebulae which have little indication of resolvability, and yet give a continuous spectrum, such as the Great Nebula in Andromeda, are not clusters of suns, but gaseous nebulae which, by the gradual loss of heat, or the influence of other forces, have become crowded with more condensed and opaque portions.
Page 237 - I believe them to be permanently solid matter, having that sort of fibrous or filamentous structure which fits them when juxtaposed by drifting about and jostling one against another to collect in flocks, as flue does in a...
Page 241 - ... water of the river is more polluted immediately after heavy rains, which force down the contents of the sewers, than after a continuance of dry weather, when its course is sluggish, or altogether arrested; and the results of experiments we directed to be made on the subject, fully establish this fact. The great increase which has of late years taken place in the population of London, and of its suburbs on every side, must also be attended by a proportionate augmentation in the quantity of extraneous...
Page 239 - At the same time it seemed to me to be ' giving out,' as it were, at its end, and a portion of the umbra between it and the penumbra appeared to be veiled with a stratus cloud evolved out of it. After a time large, very dim 'willow-leaves' seemed to be forming (conFig, i.
Page 203 - I have indicated as bearing on the astronomical question must (from the nature of the case) take precedence of all others. But there would be no difficulty in combining with them any other inquiries, of geography, geology, hydrography, magnetism, meteorology, natural history, or any other subject for which the localities are suitable. ' And I have now to request that you will have the kindness to communicate these remarks to the Royal Geographical Society, and to take the sense of the Society on...
Page 202 - I have very carefully discussed the circumstances of the coming transit, in reference to the selection of observation-sta-tions. For the Northern stations there will be no difficulty ; they will be on the Atlantic seaboard of North America, or at Bermuda; all very favourable and very accessible. For the Southern stations the selection is not so easy; the observation must be made on the Antarctic Continent; if proper localities can be found there, and if the circumstances of weather, &c. are favour-able,...
Page 89 - Positiones media, with their proper motions computed when practical from earlier observations. Another branch of what, with some propriety, may be called the Physique du del sideral, to which Struve directed much of his attention, was the determination of the law of density in the distribution of the stars with respect to the plane of the Milky Way. His researches on this subject were not indeed published until after he had removed from Dorpat, as we shall speedily see, but it is here, perhaps, that...
