    t September 1911] THE S.S.WHITE DENTAL MFG. CO. 5 SOFT=RUBBER BITE=BLOCKS Patterns supplied by Dr. S. H. Guilford The four Soft-rubber Bite-Blocks illustrated herewith, besides affording a variety of size3 sufficient to cover all requirements, have the following advantages: 1. Being elastic, they cannot injure the frailest tooth by being bitten upon. 2. Their resilience will open the jaws if partially closed, as soon as muscular relaxation takes place. 3. Being grooved, they cannot fall into the mouth or be pressed out of place by the tongue. 4. They are too large to pass back into the pharynx or be swallowed, and they cannot be broken or injured by biting. 5. They do not need a string attached, and are readily removed with a crooked finger. 6. Each block can be set at two heights, and can be placed at any point between the jaws without likelihood of slipping. Price each $0.35 DAINTREE'S ADJUSTABLE MOUTH PROP This Mouth Prop combines facility of lengthwise adjustment to suit the open of the jaws with a spring which affords the necessary elasticity. With the spring com- pressed the length at the shortest adjustment is lT3j inches; at the longest, 1£ inches. One head screws into the body, around which the other swivels, an elastic spring being confined between the swiveling head and the body. The heads are cushioned with cork, and there is a ring for the attachment of the retaining cord. All metal parts are nickel plated. Price $0.50 RUBBER APRONS FOR DENTISTS Our Rubber Aprons can be put on and taken off almost instan- taneously. They are large enough to afford ample protection to the clothing, not big enough to interfere with freedom of move- ment. The dimensions are 43 inches long and 34 inches wide at the middle line. Made of rubber cloth, and nicely finished, with the edges bound. Price each $1.00
