The Narrow Letters, B, E, F, R, S, Y (X)
(see fig. [159]).
There is a point of division in these letters about the middle of the stem or a little above (see p. [273]), and we may argue that each being composed, as it were, of two little letters—which are half-height, they are proportionately half-width: and this will be found approximately correct. B may be said to consist of one little D on the top of another, averaging respectively half the height and width of a full-sized D.
E, F, & R follow the proportions of B (see also E, 4, p. [282]). [p273]
S may be made of one little tilted O on the top of another—joined together and having the superfluous parts removed.
Y is like a little V upon a little I.
X Either narrow or wide (fig. [159]).
The Narrow letters, K, L, and P—
These forms are related to the B, E forms, but it is permissible to make them a little wider to give clearance to the angles of the K and force to the single arm and loop—the characteristic parts (see fig. [149])—of L and P.
