Four kinds of spaces; en, em, two and three em quadrates.

Accents.

These are the ordinary sorts cast to a fount, and are classified by founders as long, short, ascending, descending, kerned, and double letters.

Long Letters fill the whole depth of the face of the body, and are both ascending and descending, such in the Roman as Q and j, and in the Italic f.

Short Letters have the face cast on the middle of the body, (by founders called shank,) as a, c, e, m, n, o, r, s, u, v, w, x, z, all of which will admit of being bearded above and below the face, both in Roman and Italic.

Ascending Letters are all the Roman and Italic capitals; in the lower case, b, d, f, h, i, k, l, t.

Descending Letters are g, p, q, y, in Roman and Italic.
