Page 108 - ... a higher temperature than the cave. The phenomena of life within the cave are comparatively few but interesting. There are several insects, the largest of which is a sort of cricket, with enormously long antennae.
Page 121 - ... away on the right and left into thick darkness. Every one has heard of the dome of the Mosque of St Sophia, of St Peter's, and St Paul's ; they are never spoken of but in terms of admiration as the chief works of architecture, and among the noblest and most stupendous examples of what men can can do when aided by science ; and yet when compared with the dome of this temple, they sink into comparative insignificance.
Page 191 - Although the sun never sets whilst it lasts, plants make no mistake about the time, when, if it be not night, it ought to be ; but regularly as the evening hours approach, and when a midnight sun is several degrees above the horizon, droop their leaves, and sleep even as they do at sunset in more favored climes. " If man,
Page 221 - ... to have continued erect for many years in the Carboniferous period, when the sea happened to gain on any tract of submerged land. Submergence under salt water may have been caused either by a local diminution in the discharge of a river in one of its many mouths, or more probably by subsidence, as in the case of the erect columns of the Temple of Serapis, near Naples, to which serpulae and other marine bodies are still found adhering.
Page 371 - Not that ammonia is not an auxiliary of vegetation, but the air contains scarcely 0-0000000224, and in this proportion its effects are inappreciable. These conclusions are founded upon a great number of experiments in which the plants lived at the expense of the air without deriving any thing from the soil. For the present he confines himself to laying down these two conclusions : — 1.
Page 121 - Hall is a steep precipice, over which you can look down, by aid of blazing missiles, upon a broad, black sheet of water, eighty feet below, called the Dead Sea. This is an awfully impressive place, the sights and sounds of which do not easily pass from memory. He who has seen it will have it vividly brought before him by Alfieri's description of Filippo: "Only a transient word or act gives us a short and dubious glimmer, that reveals to us the abysses of his being ; dark, lurid, and terrific, as...
Page 371 - ... continually increasing intensity. The leaves, which at first were of a pale-green, assume a deeper and deeper tint, and for a time become almost black ; their petals are long and upright, and their surface wide and shining. In short, when vegetation has arrived at its proper period the crop is found far beyond that of the same plants grown in pure air ; and, weight for weight, they contain twice as much azote.
Page 221 - The strata at the South Joggins are nearly three miles thick, and they are known to be also of enormous thickness in the district of the Albion Mines near Pictou, more than one hundred miles to the eastward. There appears therefore little danger of erring on the side of excess, if we take half that amount or 7500 feet as the average thickness of the whole of the coal measures. The area of the coal-field, including part of New Brunswick to the West, and Prince Edward's Island and the Magdalen Isles...
Page 187 - Calcutta is about fifteen feet annually, that between the Cape of Good Hope and Calcutta averages in October and November nearly, three quarters of an inch daily ; betwixt 10° and 20° in the Bay of Bengal it was found to exceed an inch daily. Supposing this to be double the average throughout the year, we shall, instead of three, have eighteen feet of evaporation annually...
Page 290 - ANIMALS TO PLANTS. IT has been long asserted by Bory de St. Vincent and others, that there exist in nature organized bodies which are animal at one period of their lives, and vegetable at another ! This, if true, would for ever put an end to the possibility of distinguishing the two kingdoms when they shall each have arrived at their lowest forms.
