feet metallic luster; which, under some circumstances,
is objectionable. Two other methods are in use
after the burnisher has been applied, as above, the
buff or tape, with rouge, may be employed, by passing
it rapidly over the filling, till the metallic luster is
destroyed, or deadened, so as not to reflect the light
l
as before, thus leaving a very desirable finish ; and
the other method is, to stipple over the surface of the
burnished filling with the end of a piece of hard
wood—sandal wood is recommended—charged with
finely pulverized pumice. This gives a beautiful,
velvet-like surface, and is fine for fillings in the an-
terior portion of the mouth, where they are exposed
*
to view. Rotten-stone, applied either with the buff
or with hard wood, imparts a finish which, though a
little different, is equal to any of the others.
For finishing, some operators prefer to cut and
polish, instead of filing and burnishing. But neither
so good nor so fine a finish can be effected in this
way, and it is probable that economy of time and
. labor, especially the latter, suggested the method.
In all cases, the filling should have a distinct and
definite margin: the gold should be trimmed off quite
up to the border of the cavity, by passing round it a
small, sharp instrument, so as to detect and pare
down any portion that might overlap the tooth.
For, if overlapping portions are permitted to remain,
