plaster model having been obtained from this, a piece of FIo. 1.
silver of the proper length, breadth, and thickness is
then cut, in the manner represented in the diagram,
Fig. 1. The cross-piece A being intended to rest upon A
the articulating surface, while the two ends B are to be
bent, to serve as bands by clasping the sides of the
tooth, as in Fig. 2. There is no occasion for swedging the FIa. 2.

plaster model by means of the pliers.
The appliance, as described, is intended for a tooth,
standing alone, but it can be readily adapted to a tooth
in close proximity to others, by accommodating the
bands to the modifying circumstances. J.. l' Q.

SALIVARY CALCULT.-Through the courtesy of Dr. James E. Garretson, we had an opportunity of examining, a short time since, a very rare
and valuable specimen which he had removed a few days before from the
mouth of an old lady, aged. sixty-nine. It was a large salivary calculus,
somewhat longer and about as thick as a pigeon's egg, which had been
formed by the right sublingual gland.
The doctor informed us that, eighteen years ago, the patient was kicked
under the chin by an unruly cow. About a year after this accident a
tumor began to develop in the region of the sublingual gland; this continued to enlarge for several years until it attained the size of a pullet's
egg, when further development was arrested. From that time the patient had experienced considerable inconvenience, not only from occasional
attacks of inflammation in the adjacent parts, but also from the continued
presence of such a large body in the oral cavity.
The tumor had been examined by a number of medical practitioners,
and pronounced cancerous in its character, and the patient advised not to
submit to an operation or to permit any further manipulation for the purpose of ascertaining the nature of the affection.
The patient having been sent to Dr. Garretson, after a careful examination, he felt satisfied that there was nothing to warrant the impression that
the tumor was malignant; on the contrary, he concluded that it was a
ranula, but without deciding what the contents of the cyst, if present
would be. On the strength of these convictions, he suggested the propriety of passing a scalpel through it, but the patient declined. Failing
to obtain her sanction to this on several subsequent occasions, he at last,
without apprising her of what he was doing, suddenly passed his bistoury
