P. 64. A nib may be _sharpened_ several times, before it is re-cut, by paring it underneath (fig. _a_).
Pp. 73 & 81. The thin finishing-strokes of j, & F, G, J, N, are made with the point of the nib--see note p. 63 above.
P. 99. The plan of a paper scale is shewn in fig. _b_.
P. 109. The dots for lines were often pricked through the edges of the book-sheets which were cut off after ruling (fig. _c_).
P. 118. The spread or _wedge-shaped_ thin stroke, sometimes very strongly marked, is common in early forms (fig. _d_).
P. 144. [/V] & [/R]: better (pen) forms of these are shewn in fig. _e_.
P. 208. Ornamental Letter forms may _consist of_ flourishes, patterns, leaves, flowers, &c. (see fig. _f_).
Pp. 215-217. _Diapering_ generally means the variegation, figuring, or flowering, of a plain or patterned surface, with a finer pattern (see fig. 191_a_). Some diagrams of simple patterns (_g_-_g_^2 from modern _cantagalli_ ware) are shewn in fig. _g_. Note: the more solid penwork line-fillings in figs. 87, 126, make effective framing borders (see fig. _h_).
Pp. 219-220. Note: the principle of breaking straight or long lines, mentioned in regard to background edges (p. 190), and illustrated in the line-finishings (fig. 126) and flourishes (fig. 79), is related to _branching out_ and is re-creative, whereas the prolonged line is tiresome (see figs. _k_, _k_^1, & _comp. k_^2).
P. 249. The B & D should be _round-shouldered_--see note p. 280 below. [p-xxvi]
P. 260. It is sometimes better to make narrow forms than to combine wide ones--example fig. _l_.
Pp. 270-275. The large types--"Old Face" Pp. 280-288. (founded on Caslon Type) and "Old French" (modern) respectively --are used in these pages as reference or index letters (not as models).
P. 280. Generally _round-shouldered_ letters have finer and more stable forms than square-shouldered, and generally emphasis should be laid on the _strong, thick stroke running obliquely down from left to right_ (@), while the weak, thin stroke (/) is rather to be avoided (see fig. _m_). The writing used in the diagrams in this book, considered as a formal hand, shews a little too much of the thin stroke (see p. 485).
