He was not kept waiting long. He heard voices approaching, then a clear, soft laugh, and she was there; but oh, retribution! with her, supporting her on his arm, was Professor Silex!
This naturalist says, that calcareous stones become silex by a certain chemical operation; and that those flinty bodies, in being exposed upon the surface of the earth, out of their natural bed, are again, by a contrary chemical operation, changed from flint to a calcareous substance.
In heating the elements aforesaid, certain chemical combinations will have taken place, and monosulphide of calcium, combined with carbonate of lime, magnesia, and silex, will be the result of such ignition.
"And I wish you'd stop behaving as if I were your daughter. I don't know what ails you this morning; but if you go on this way I shall call you Professor Silex all the time. How would you like that?" A passionate exclamation rose to his lips, and died there. A spasm of bitter pain made his face for a moment hard and stern.
"I am less surprised at that than I am with the flint, which appears almost incomprehensible." "Nothing is impossible with God; there is a rush in Holland which contains much more silex than the wheat-straw, and it is employed by the Dutch to polish wood and brass, on that very account.
On the other hand the immediate superposition of the limestone of Cumanacoa on mica-slate and transition clay-slate the rarity of the petrifactions which have not yet been sufficiently examined the strata of silex passing to Lydian stone, may lead to the belief that the soils of Cumanacoa and Caripe are of much more ancient formation than the secondary rocks.
The men especially pride themselves upon canoe-making; the favourite wood is the buoyant Okumeh or bombax, that monarch of the African forest. I have seen a boat, 45 feet 10 inches by 5 feet 11 inches in beam, cut out of a single tree, with the Mpano or little adze, a lineal descendant of the Silex implement, and I have heard of others measuring 70 feet.
It is my likeness if it be his glass. And a narrative that is true to the Varieties of Life is every Man's Novel, no matter from what shores, by what rivers, by what bays, in what pits, were extracted the sands and the silex, the pearlash, the nitre, and quicksilver which form its materials; no matter who the craftsman who fashioned its form; no matter who the vendor that sold, or the customer who bought: still, if I but recognize some trait of myself, 't is my likeness that makes it 'My Novel."
Carbonate of lime, for example, sometimes carries with it a considerable quantity of silex into its own form of crystal, the silex being mechanically mixed as sand, and yet not preventing the carbonate of lime from assuming the form proper to it.
Even the denser silicious stones are penetrable by fluids and the coloring matter they contain, to such an extent that agates and other forms of silex may be artificially stained through their substance. The colors of the stones cut at Oberstein are generally produced, or at least heightened, by art.
