Էջ 55 - ... obelisks, their pyramids, and statues, indicate, in a manner not to be misunderstood, that instruments of the best-tempered metal must have been placed in the hands of their artists. Africa affords a considerable quantity of gold, which is always obtained in the form of dust and rolled masses, and is found in the sand of rivers, or the alluvial soil of valleys near a mountain-range. The position of Egypt deprives it of this source of wealth ; but in the countries above the Cataracts, especially...
Էջ 291 - I might be induced to adopt the contrary opinion. But I am inclined to attribute the effect of vitriolization observed in some of the pyrites, not so much to the proportion, as to the state of the sulphur in the compound ; for I much suspect, that a predisposition to vitriolization, in these pyrites, is produced by a small portion of oxygen being previously combined with a part, or with the general mass, of the sulphur, at the time of the original formation of these substances, so that the state...
Էջ 74 - Jonson, the great dramatist, was co-eval with Shakspeare. The silver mines of Mexico and Peru far exceed in value the whole of the European and Asiatic mines.

It is also known that at a very early period, domestic utensils and instruments of war were made of a compound of this metal and tin; even during the Trojan war, as we learn from Homer, the combatants had no other...
Էջ 502 - One thousand cwt. are yearly expended for this purpose; and to Spain alone, the value of 18,000 livres is sold. In Prussia, the amber-diggers, who name it black amber, cut it into various ornamental articles...
Էջ 55 - Desert, there are tracts remarkable for the quantity of gold they contain. Thus the flat country, which extends from the foot of the mountains in which are situated the sources of the Gambia, Senegal, and Niger, has, from an early period, afforded gold.
