The ruling stylus has a blunt point, which indents the paper, but does not scratch it. A stout pin bent to a claw shape and held in a piece of wood does very well (fig. [72]). [p109]
Under the writing paper there should be a “pad” of ordinary paper (or blotting paper).
The marginal lines are ruled from head to foot of each leaf (a, fig. [73]). Besides being a guide for the writing, they give an appearance of straightness and strength to the written page.[22]
The writing lines are ruled across, between the marginal lines, their places having been indicated by equidistant dots (b, fig. [73]).
A dozen or more of the small sheets of the book are piled together on a board with their top edges exactly coinciding, and the pattern sheet is accurately placed on the top of the pile. The pile of sheets may be fixed by a narrow piece of wood placed across and screwed down (fig. [74]). (See Addenda, p. [25].)
