I thought fitting to give you a word or two, wherefore I have not made the crosse pricked lines to passe through the figures.
The reason is, 1 because the figure would have beene thereby somwhat defaced; 2 because some chuse rather to draw without such rules; 3 for others with a ruler and black lead plummet they may crosse the figures through, and with white bread crums take out the same againe at pleasure.
