![Use none but the very best vulcanite. Dentists save money at costly risk of their reputation in using poor materials. They fake, maybe unwittingly, on a mighty small financial scale, in using poor grades of rubber— in fact, poor grades of any other material—in dental work. Pack carefully; use dry heat; squeeze light- ly, and close very slowly. And, no matter how experienced you may be in guessing, you 'd better use the trial cloth, especially in lower cases. Use pink rubber in the center of thick upper rims and weighted rubber in thick lower ones to prevent jjorosity, excepting in front. The trial cloth is that which comes between sheets of rubber. Don't wash the starch quite all out. Then kee]) it wet. lest it may stick to the hot, soft vulcanite. HOW TO VULCANIZE. Only a few points here; and still fewer of them new. But you are a rare flock of ])ros- thetic birds if some of you don't need to have some, even of the old ones, re^suggested to you. He that hath ears, let him hear—it again. Then vulcanize at the lowest point possible Avith your tried- and known thermometer and vulcanizer. Xot all thermometers register tem- perature alike. Xor, indeed, do all vulcanizers Avork alike. I have carefully changed the same thermometer to different vulcanizers and found pronouncedly different results. Then test your vulcanizer often enough to know for yourselves, and not for another, just how it works. Then, in practical use, run it at the lowest vulcanizing temperature and long enough to a tougli^liardness, and not a brittle one.
