With the obturator in position, a model of the remaining hollowwas taken, and from this a silver plate was struck, which fittedaccurately into the hollow and under the right ala of the nose; asmall tongue of silver was adjusted over the bridge of the nose, andon to this the spectacles were subsequently soldered.
