On other spots, instead of silex, carbonate of lime was precipitated, together with more or less of the nucaceous sediment, and gave rise to saccharoidal limestones. At a later period, when the ocean was yet further cooled down, rock-salt and sulphate of lime were locally precipitated in a similar mode.
We have wandered far from the consideration of the propensity of certain species of plants to take up special compound substances from the earth; but the wide-spread silex, with which we set out, displayed so interesting a field of observation, that it could not be resisted, and encouraged a disposition to rove, which has been to us instructive and entertaining.
Assyrian glass was either transparent or stained with a single uniform color. It was composed, in the usual way, by a mixture of sand or silex with alkalis, and, like the Egyptian, appears to have been first rudely fashioned into shape by the blowpipe. It was then more carefully shaped, and, where necessary, hollowed out by a turning machine, the Marks of which are sometimes still visible.
The thoughtlessness which can allow an inference to be extended from a product of disease possessing this susceptibility of multiplication when conveyed into the living body, to substances of inorganic origin, such as silex or sulphur, would be capable of arguing that a pebble may produce a mountain, because an acorn can become a forest.
Some of our polishing powders are made from these rocks. Formed of pure silex, these rocks are made up of the skeletons of organisms of many exquisite forms, Foraminiferæ. The Pyramids are said to be built of rocks formed by these organisms. "No single group of the animal kingdom," says Mr.
It is time for a change of some sort, for the worse or the better, when we get habitually, and by a social rule, water for milk, brickdust for chocolate, silex for butter, and minerals of one kind and another for bread; when our drugs give the lie to science; when mustard refuses to 'counter-irritate, and sugar has ceased to be sweet, and pepper, to say nothing of 'ginger' is no longer 'hot in the mouth. The question in speculative philosophy at present is
This done, Silex Corundum made another address, and at its close a great blackboard was brought forward, some pieces of chalk were handed to Mr. Roumann and to Professor Henderson, and by signs they were invited to illustrate something of themselves and their wonderful journey. "What shall we draw?" asked Mr. Henderson.
Silex Corundum appeared to understand, and he indicated that the unfortunate man would receive attention. The travelers were then led out of the palace. They found instead of being urged along by the thought power, however, that they were now allowed to walk.
Huxley's answer is, "The winds and waves of the Bay of Biscay have not much consciousness, and yet they have with great care 'selected, from an infinity of masses of silex, all grains of sand below a certain size and have heaped them by themselves over a great area.... A frosty night selects the hardy plants in a plantation from among the tender ones as effectually as if the intelligence of the gardener had been operative in cutting the weaker ones down."
What I claim is a phosphorescent composition consisting of monosulphide of calcium, combined with carbonate of lime, magnesia, and silex, substantially as described. Orlando Thowless, of Newark, N.J., obtained a patent for a process of manufacturing phosphorescent substances dated November 8, 1881.
