Pagina 130 - Liliacese, &c., species in only two or three genera have the power of climbing, the conclusion is forced on our minds that the capacity of revolving, on which most climbers depend, is inherent, though undeveloped, in almost every plant in the vegetable kingdom.
Pagina 155 - This mountain is covered by a dense forest, with the exception of a level spot of about half a mile in length and a quarter of a mile in width...
Pagina 136 - Synopsis of the Polyps and Corals of the North Pacific Exploring Expedition.
Pagina 138 - Some isolated portions of meteorites have also a structure very similar to that of stony lavas, where the shape and mutual relations of the crystals to each other prove that they were formed in situ, on solidification.
Pagina 408 - The muscle is a machine for the conversion of potential energy into mechanical force. 2. The mechanical force of the muscles is derived chiefly, if not entirely, from the oxidation of matters contained in the blood, and not from the oxidation of the muscles themselves. 3. In man the chief materials used for the production of muscular power are non-nitrogenous ; but nitrogenous matters can also be employed for the same purpose, and hence the greatly increased evolution of nitrogen under the influence...
Pagina 137 - ... of the sun, at a period indefinitely more remote than that of the occurrence of any of the facts revealed to us by the study of geology — at a period which might in fact be called pre-terreslrial. Broomfield, Sheffield, July, 1866. 2. On the Mineralogical Structure of Meteorites...
Pagina 128 - I have more than once gone on purpose during a gale to watch a Bryony growing in an exposed hedge, with its tendrils attached to the surrounding bushes ; and as the thick and thin branches were tossed to and fro by the wind, the tendrils, had they not been excessively elastic, would instantly have been torn off and the plant thrown prostrate. But as it was, the Bryony safely rode out the gale, like a ship with two anchors down, and with a long range of cable ahead to...
Pagina 88 - The two merge and overlap so that it is impossible to tell where one begins and the other ends.
Pagina 138 - This sometimes gives rise to a structure remarkably like that of consolidated volcanic ashes, so much, indeed, that I have specimens which, at first sight, might readily be mistaken for sections of meteorites. It would therefore appear that, after the material of the meteorites was melted, a considerable portion was broken up into small fragments, subsequently collected together, and more or less consolidated by mechanical and chemical actions, amongst which must be classed a segregation of iron,...
