    When a vulcanite plate breaks, especially if in the mouth, the dentist ought to be re- sponsible for it. For it is next to impossible to break a pro2)erly made plate of really good stuff; and it is a dentist's duty to test his ma- terial before promiscuously using and selling it. It Mould pay you all, and at the same time be a good educator of the people. to make and keep several toothless plates to jmnp up= and=down on, and to throw against the wall, to show your patients zchat you can do; and then do it lionestly. I insist that a pro])erly made and properly titled vulcanite plate, of good ma- terial, zcill not brcaJc in the mouth; nor will it out of the mouth without considerable effort. The 'cowshorn samples sent out by the man- ufacturers are proof of that. There are numerous coverings for plaster models, to prevent the usual deterioration of rubber in vulcanizing contact with gypsum. There are some excellent liquid glosses. Af- ter strongly advising those of you who dont use anything, to use soincthins!;, I will state that 1 still use thin tin^foil. preferably number four. And even thni gold foil is not too expensive for the benefit, if no tin is at hand. The claim that thin foil, placed evenly all over a model, will change the fit of a plate, on flesh tissue, is high=grade theori/. backed by low-grade faet. The model is at first })ainted with very thin varnisli, and the foil then hurriedly smoothed on with a connnon shaving=brush. Then the foil is as liurriedly smoothed over with pulverized soajjstone on the brush. (We licked the foil on before the days of dangerous microbes.) If for no otlier one of several good reasons. I would thus cover my i)laster models to bring them out of the flask clean and save time in
