could be used to reproduce not just illustrations, but texts containing special
characters (such as scholarly works on hieroglyphs), or integrated with drawings
(such as military manuals or mathematical works). In 1845 Benjamin P. Wilme, a
civil engineer and surveyor in London, produced this treatise on letterforms for
'the Schoolmaster, the Architect, Engineer, and Surveyor, and their pupils'. It
gave only brief instructions on lettering, but included 26 lithographed plates
showing a wide variety of alphabets and letterforms.
