5. (Typog.)
(a) A raised letter, figure, accent, or other character,
cast in metal or cut in wood, used in printing.
(b) Such letters or characters, in general, or the whole
quantity of them used in printing, spoken of
collectively; any number or mass of such letters or
characters, however disposed.
[1913 Webster]
Note: Type are mostly made by casting type metal in a mold,
though some of the larger sizes are made from maple,
mahogany, or boxwood. In the cut, a is the body; b, the
face, or part from which the impression is taken; c,
the shoulder, or top of the body; d, the nick
(sometimes two or more are made), designed to assist
the compositor in distinguishing the bottom of the face
from t`e top; e, the groove made in the process of
finishing, -- each type as cast having attached to the
bottom of the body a jet, or small piece of metal
(formed by the surplus metal poured into the mold),
which, when broken off, leaves a roughness that
requires to be removed. The fine lines at the top and
bottom of a letter are technically called ceriphs, and
when part of the face projects over the body, as in the
letter f, the projection is called a kern.
[1913 Webster] The type which compose an ordinary book
font consist of Roman CAPITALS, small capitals, and
lower-case letters, and Italic CAPITALS and lower-case
letters, with accompanying figures, points, and
reference marks, -- in all about two hundred
characters. Including the various modern styles of
fancy type, some three or four hundred varieties of
face are made. Besides the ordinary Roman and Italic,
some of the most important of the varieties are
[1913 Webster] Old English. Black Letter. Old Style.
French Elzevir. Boldface. Antique. Clarendon. Gothic.
Typewriter. Script.
[1913 Webster] The smallest body in common use is
diamond; then follow in order of size, pearl, agate,
nonpareil, minion, brevier, bourgeois (or two-line
diamond), long primer (or two-line pearl), small pica
(or two-line agate), pica (or two-line nonpareil),
English (or two-line minion), Columbian (or two-line
brevier), great primer (or two-line bourgeois), paragon
(or two-line long primer), double small pica (or
two-line small pica), double pica (or two-line pica),
double English (or two-line English), double great
primer (or two-line great primer), double paragon (or
two-line paragon), canon (or two-line double pica).
Above this, the sizes are called five-line pica,
six-line pica, seven-line pica, and so on, being made
mostly of wood. The following alphabets show the
different sizes up to great primer.

[1913 Webster] The foregoing account is conformed to
the designations made use of by American type founders,
but is substantially correct for England. Agate,
however, is called ruby, in England, where, also, a
size intermediate between nonpareil and minion is
employed, called emerald.
[1913 Webster]
Point system of type bodies (Type Founding), a system
adopted by the type founders of the United States by which
the various sizes of type have been so modified and
changed that each size bears an exact proportional
relation to every other size. The system is a modification
of a French system, and is based on the pica body. This
pica body is divided into twelfths, which are termed
"points," and every type body consist of a given number of
these points. Many of the type founders indicate the new
sizes of type by the number of points, and the old names
are gradually being done away with. By the point system
type founders cast type of a uniform size and height,
whereas formerly fonts of pica or other type made by
different founders would often vary slightly so that they
could not be used together. There are no type in actual
use corresponding to the smaller theoretical sizes of the
point system. In some cases, as in that of ruby, the term
used designates a different size from that heretofore so
called.
