Stereotype consists of plates of metal taken, by casting, from a forme of type set up for the purpose; an impression in plaster of Paris is first taken, and from this the metal impression is cast, so that the original forme of type may be “distributed” or taken to pieces, and again used, while the stereotyped impression can be preserved for any future printing.
LUCIFER-MATCHES.
FILLING THE BOXES.
These convenient matches, which have completely superseded the old apparatus of flint, steel, and tinder-box, may be looked upon as one of the improvements derived from chemistry, for phosphorus—the necessary ingredient—till lately sold at half-a-crown an ounce; such a price would, of course, prevent its being used for so general a purpose as match-making. But when chemistry devised means of preparing it on a large scale, and at a low price, then its application was soon perceived.
