OF UNIVF OF SYSTEM EASY LETTERING. J. HOWARD CROMWELL, PH.D., SPON & CHAMBERLAIN, 12 CORTLANDT STREET, NEW YORK. 1897. C 7 COPYRIGHT, 1887, BY . ..WM. QHAMBERLAIN. "' * ' '* "j PREFACE. The formality of a preface may seem scarcely necessary for the supplementing of a system as simple and comprehensible as the one herewith presented. We have but to divide any surface we may wish to letter into squares (or parallelograms as the case may be), in pencil lines ; form the required letters, in ink or paint, and accord- ing to the style chosen ; erase the pencil lines, and the lettering is complete.
