The letter H is to be formed of two broad, great, & vertical limbs of
the height of the square, in such fashion that their extremities, being
produced exteriorly, shall touch the four angles of the square, a. c.
and b. d. respectively. Now in what fashion the projections of the
broader limbs of letters are to be rounded out at top and bottom and on
either side, you have been instructed; for in any letter you please, any
broad and vertical limb is to be depicted at top and bottom thrice as
broad as at its middle: provided always it is not joined to a narrower
limb. So when this has been accomplished, then draw your narrower
transverse limb upon the line e. f. as is shown below.
