times made with the edge square ; but the round
edge is the better form. The edge is parallel with
the handle in the ordinary lancet. (Fig. 82.) This

form is used for separating the gum from the buccal
and palatal surfaces of the tooth. A lancet with the
edge transverse to the shaft is required for separating
the gum from the proximal portions of the teeth.
The blade of this should be of the same general
form as that already described, except that it should
be quite narrow—in no case more than two lines
wide. (Fig. 83.) Gum-lancets are made with the

blade set in a socket on the end of the shaft, so that
it can be rotated and set to any angle, to meet every
case.
A very ingenious instrument, invented by Dr.
Merry, and denominated " Merry's Revolving Gum-
lancet," has recently been brought to the notice of
the profession. This is a very excellent instrument
