Note 27 — Chapter X · THE EXHIBITION OF 1862.
Reading edition
An illustration fell under my notice a few days after this paragraph was printed. A new work on Geometrical Drawing, commissioned by the Committee of Council on Education, was published by Professor Bradley. I have not been able to find in it a single word concerning “Mechanical Notation,” not even the very simplest portion of that science, namely, the Art of Lettering Drawings. It would seem impossible that any Professor of so limited a subject could be ignorant of the existence of such an important addition to its powers.
