Page 291 - He hath measured the waters in the hollow of his hand, and meted out the heavens with a span ? Thine, O Lord, is the greatness, and the power, and the glory, and the victory, and the majesty.
Page 291 - Who hath measured the waters in the hollow of his hand, and meted out heaven with the span, and comprehended the dust of the earth in a measure, and weighed the mountains in scales, and the hills in a balance?
Page viii - The objects of the Association are, by periodical and migratory meetings, to promote intercourse between those who are cultivating science In different parts of America, to give a stronger and more general impulse and more systematic direction to scientific research, and to procure for the labors of scientific men increased facilities and a wider usefulness.
Page 280 - ... has been felt in remote regions by means of the winds, and the effects which a greater or less amount of moisture brought by them would produce. In the case of Utah, we have an example of drainage that has been cut off, and an illustration of the process by which nature equalizes the evaporation and precipitation. To do this, in this instance, she is salting up the basin which received the drainage of this inland water-shed. Here we have the appearance, I am told, of an old channel by which the...
Page 206 - It is well known that calcareous springs deposit carbonate of lime in crystalline forms. The salt had been held in solution by carbonic acid contained in the water. Upon reaching the surface under less pressure and the influence of a high temperature, its carbonic acid is given up, and with it a precipitate of carbonate of lime takes place.
Page 117 - This atmosphere can extend no further than to the orbit of a planet, whose periodical revolution is performed in the same time as the sun's rotary motion about its axis, or in twenty-five days and a half : therefore it does not extend so far as the orbits of Mercury and Venus, and we know that the zodiacal light extends much beyond them.
Page 340 - Vegetables," from which he drew the inference, " that an animal must be deprived of life before it can be frozen ;" and "that plants when in a state of actual vegetation, or even in such a state as to be capable of vegetating under certain circumstances, must be deprived of their principle of vegetation before they can be frozen
Page 285 - And admitting the vapor-springs for that valley to be situated in the direction supposed, the rising up of a continent from the bottom of the sea, or the upheaval of a range of mountains across their route in certain parts of America, Africa or Spain, might have been sufficient to rob the air of the moisture which it was wont to carry away and precipitate upon this great inland basin. See how the Andes have made Atacama a desert, and of Western Peru a rainless country, simply by the rising of a mountain...
Page 277 - It may be that the question suggested by my researches has no bearing upon the Dead Sea ; that local elevations and subsidences alone were concerned in placing the level of its waters where it is. But is it probable that, throughout all the geological periods, during all the changes which have taken place in the distribution of land and water surface over the earth, the winds, which in the general channels of circulation pass...
Page 296 - The residue of the soil left upon the filter, consisting chiefly of silica and alumina, was found, after drying, in every instance, to be more or less stratified, and that too by divisional planes in some cases not at all coincident with any division of the materials, although this is apt to take place. The strata so produced...
