If it be ever admissible, it is when fusible metal is used, which admits of more management in some particulars than gold; but, as has been already observed, where a tooth cannot be stopped without using the fusible metal, it is much better to remove it at once. The operation of stopping, when there is no mechanical obstruction to be removed, is simply this. The aperture should be first di- vested of every particle of caries ; this must be done most perfectly; for should any portion, however small, be left, the operation will not succeed. For this purpose various instruments are requisite. If the aperture is small, having an irregular shape, the enamel should be first cut with the file-headed instrument [Fig. 2,] to a sufficient size; next, a broach-shaped instru- ment, [Fig. 3,] the size of the aperture, should be introduced, having a curve, if the situation
