Note 17 — Chapter VII
S. R. (Sylvester Rosa) Koehler translation
(p. 50.) Gravers are of different shapes, according to the nature of the line which they are intended to produce. They are sometimes kept at the hardware-stores, as, for instance, by A. J. Wilkinson & Co., 184 Washington St., Boston. This house also issues an illustrated catalogue of engravers' tools.
