Are not its uses very extensive?

Yes, both in the arts and in chemistry:  it is well known to be a principal ingredient in the preparation of gunpowder and fire-works; it is also used for whitening wool, straw, silk, &c.; many other matters exposed to the vapors of sulphur when burning, quickly lose their color, which no other substance had been able to destroy.  Sulphur is also frequently found in mineral waters.

Whence are the greatest quantities of Sulphur brought?

The largest quantities are brought from Saxony, in irregular masses, which are afterwards melted and cast into small rolls.  There are about four species of sulphur; namely, the yellow native sulphur, which in its purest state is clear, and of a pale straw color, found in the gold mines of Peru; in Hungary, and some other places:  the green native sulphur, which is harder than the other, is found in small crust-like masses; this sort is chiefly confined to Mount Vesuvius:  and the grey native sulphur, common in Iceland and many other places.  Native sulphur is also found at the coal mines, near Richmond, Virginia; in Connecticut, Pennsylvania, and other parts of the United States.

Which is the most rare and beautiful of all the kinds?

The red native sulphur; it is mostly of a fine glowing red, very bright and transparent; it is found, like the first-mentioned sort, in the gold mines of Peru.  Common sulphur, such as is used in trade and the arts, is of a pale yellow color; and possesses a peculiar and disagreeable smell, particularly when heated or rubbed.  This is mostly extracted from the metallic sulphurets, and is commonly called brimstone.  It is the sort employed in making matches.

Is there not another substance also employed in the manufacture of matches?

Yes:  Phosphorus, a peculiar substance, chiefly of animal origin.  It is mostly procured by the decomposition of the phosphoric acid which is found in bones.  It was accidentally discovered at Hamburgh, in 1669, by an alchemist named Brandt.

What is the nature of Phosphorus?

It is a solid, inflammable substance, which burns when in contact with atmospheric air.  It is used in various chemical experiments, and for making matches; for various kinds of fire-works, &c.  It will combine with all metals except gold and zinc; and also with some earths.  Some animals, as the glow-worm, possess very peculiar phosphorescent qualities.

What is Arsenic?

A heavy metallic substance, very volatile, and highly inflammable; so caustic or corrosive to animals, as to become a violent poison in all its states.  In its metallic state it is used in several of the arts:  it is employed in the manufacture of factitious metals:  it is of use to the dyer in forming some of his colors; and for that purpose is generally combined with potassa.  It is used in the making of small shot, and also in the manufacture of glass, to which it gives transparency; in whitening copper; in calico printing; in the preparation of colors for the painter; and in the working of platina, and some other metals, to render them more easily fusible.
