    Fig. 1.—The writer’s modificatiou of the ori- ginal dovetail dilator. It is unnecessary to delay the reader with any further description of that design, as I am informed a dilator cannot be constructed of small calibre according to it, and at the same time have the strength which should be possessed by an instrument for the instanta- neous method of forcing urethral strictures. Fig. 1 represents a dilator constructed upon the above-mentioned plan, but with some modifications of mine in the handle and con- ductor, the latter being round and not trian- gular as originally proposed. If the reader will study Figs. 2 and 3 he can scarcely fail to understand the difi'crence between the original design and that of Fig. 1. Fig. 2.—Diagrammatic vertical section of the dovetail conductor, forcer, and blades, with separate piece of forcer, of the original dovetail dilator. Fig. 3.—Diagrammatic vertical secUon of the dovet;dl conductor, forcer, and blade.'i, with separate j)iece of forcer, of the author’s modification of the original dovetail dilator.
