Seite 51 - In very clear and very deep sea water this condition is approximately fulfilled, and hence the extraordinary darkness of such water. The indigo, to which I have already referred, is, I believe, to be ascribed in part to the suspended matter, which is never absent, even in the purest natural water, and in part to the slight reflection of the light from the limiting surfaces of strata of different densities.
Seite 178 - ... the King himself held the same. This was the origin of the Palatine rights of the Bishops of Durham. 782. A synod held at Aycliffe ; and again in 789. 792. At Sedgefield and neighbourhood a very destructive ice storm occurred, filling the streets to the depth of two feet with pieces of ice, varying from the size of a marble to that of a man's head. — A synod held at Finchale. 792. A synod held at Finchale Priory ; another in 798 ; and a third in 810. 793. The Danes burnt and plundered Monkwearmouth,...
Seite 51 - ... microscopic magnitude. It would still behave substantially as the larger plate, sending to the eye its modicum of green light. If the plate, instead of being a large coherent mass, were ground to a powder sufficiently fine, and in this condition diffused through the clear sea-water, it would send green light to the eye. In fact, the suspended particles which the home examination reveals act in all essential particulars like the plate, or like the screw-blades, or like the foam, or like the bellies...
Seite 90 - To account for the great depositions of salt in the lower parts of this basin, it is necessary to suppose that some barrier must have been afterwards interposed to prevent the free communication of the waters of the sea with those thus collected; and the general course of the streams, the position of the beds of rock-salt, and the contractions in the valley of the Weaver, which appear below Nortlnvich at Anderton and Frodsham, point out with some distinctness the ptace where these obstructions may...
Seite 52 - Salpa1 guts gave us, in addition to the finer tow nets, immense collections of radiolarians, diatoms and Dinoflagellata, many of which have been considered to live at great depth and upon the bottom. The number of diatoms found in this tropical region is most interesting. They have usually been considered as characteristic of more temperate and colder, regions. On several occasions the surface waters were greatly discolored by their presence, and the extent of their influence on the bottom deposits...
Seite 224 - ... eccentricity. It postulates a simple mode of origin of the nebula connected with the not improbable event of a close approach of the ancestral sun to another large body, but the main hypothesis is not dependent on this postulate. It assigns the gathering-in of the planetesimals to the crossing of the elliptical orbits in the course of their inevitable shiftings. Out of this process and its antecedents, it develops consistent views of the requisite distribution of mass and momentum, of the spacing...

Seite 224 - ... peculiarities. It deduces a relatively slow growth of the earth, with a rising internal temperature developed in the central parts and creeping outward. With such a mode of growth, the stages of the earth's early history necessarily depart widely from those postulated by the Laplacian and the meteoritic hypotheses.
Seite 231 - ... if the earth contained throughout its volume as much radium as a sample of clay examined by them the temperature gradient at the surface would be about accounted for. I have recently examined a large number of rocks, both igneous and sedimentary, and have been led to the conclusion that there is very much more radium in all of them than would be needed to maintain the earth's internal heat if the earth were constituted of rock throughout. From this I conclude that the interior of the globe does...
Seite 224 - ... the nebula as the nuclei of the future planets, and the nebulous haze as matter to be added to these nuclei to form the planets. It assumes that both the knots and the particles of the nebulous haze moved about the central mass in elliptical orbits of considerable, but not excessive, eccentricity. It postulates a simple mode of origin of the nebula connected with the not improbable event of a close approach of the ancestral sun to another large body, but the main hypothesis is not dependent on...
