The clinician claimed the followingadvantages for the soldering stand: (1)By means of the hinged portions of the DENTAL SOCIETY OF THE STATE OF NEW YORK. 229 blowpipe, the flame may be directed uponany portion of the inner circumferenceof the soldering block, and may be ad-justed so that it will remain in any posi-tion to which it is moved. This allowsthe operator to pick up solder and adjustthe parts of the appliance while the nameof the blowpipe is firmly held in the. exact position desired. (2) The solder-ing block may also be moved in a circlewithin its own circumference, thus doingaway with the otherwise necessary chang-ing of position of a heated plaster case.(3) The blowpipe may be manipulatedwith the left hand if desired, leavingthe right hand free for picking up solder,etc. Dr. E.

The in-vestment is first dried out, the solderplaced in position, and a Bunsen flamedirected on the under surface of the in-vestment. A cone is then made of twothicknesses of sheet asbestos, the diam-eter of the cone being one inch larger atthe base than at the top, or 2V by .The cone is then placed over the in
