But it is this author's explanation of that petrifaction which is our present object to consider; and, as he is so particular in giving us his theory upon the subject, it is easy to detect the error of his reasoning. The third section has for title, "Generation du Silex et Quartz de la Pierre Puante."
In the case of two flint stones, the light that is perceived is of an entirely different nature, for it is a phosphorescence which is produced, even by a very slight friction, not only between two pieces of silex, but also between two pieces of quartz, porcelain, or sugar; and that the heat developed is but slight is proved by the fact that the phenomenon may occur under water.
De Mortillet supposes that this being was an animal intermediate between man and the monkey, which he calls the anthropopithecus. This precursor of man made use of fire for splitting silex and manufacturing from it instruments whose cutting edge he perfected by means of a series of retouchings produced by slight percussions upon one of the surfaces only.
The produce of nitrogen in clover and peas, which agriculturists will acknowledge require no nitrogenised manure, is far greater than that of a potato or turnip field, which is abundantly supplied with such manures. Lastly. On a morgen of meadow-land, we obtain in plants, containing silex, lime, and potash, 984 carbon, 32.2 nitrogen.
The shrewd close fisted Auvergnat! A girl without a fortune! Cayrol Silex as he was called in the commercial world on account of his hardness. This living money-bag had a heart then! It was necessary to believe it since both money-bag and heart had been placed at Mademoiselle de Cernay's feet. This strange girl was certainly destined to millions.
This water was found to be highly charged with carbonic acid holding lime in solution. It is well known that the waters of all springs are more or less charged with earthy, alkaline, or metallic ingredients derived from the rocks and mineral veins through which they percolate. Silex is especially abundant in hot springs, and carbonate of lime is almost always present in greater or less quantity.
"Quos super atra silex jamjam lapsura, cadentique Imminet assimilis."
The rocks split like planks of deal beneath the axe. A jet of fire, smoke, and debris sprang from the middle of the grotto, enlarging as it mounted. The large walls of silex tottered and fell upon the sand, and the sand itself, an instrument of pain when launched from its hard bed, riddled the faces with its myriad cutting atoms.
They started one morning in a large boat, which Silex Corundum, the ruler of Mars, had placed at their disposal, and in a short time were approaching the distant hills, at the foot of which was the great lake. The boat moved swiftly, the controlling mechanism consisting of three little knobs on the outside of the box containing the Cardite.
The circumstance, that all canes, as well as straws and hollow grasses, have an epidermis of silex, is one of the most singular facts in nature. Mr.
