The fact is, a rubber plate should come out of the flask clean, fairly smooth, and almost finished. It should need no trimming, other than of small excess extensions; no filing, nor scraping, as to its shaping. And no grinding. LAST FINISHING CARE IN ARTICULATION. Ten to t^venty minutes will finish our double set of teeth, after out of the flask, if we have modern lathe machinery. We '11 slip them into patient's mouth to see whether or not they come together properly. Xor will we jump to any hasty conclusion about it; for we have all been fooled in that way. We have quickly concluded articulations w^ere all right, when a few hours, or days, ]:)roved otherwise. And sometimes we have hastily said to ourselves, if not to our patients: ''They are all wrong; you hit wrongl}, and I 11 have to make them over; when a little time showed a mistake, in our favor. Xow, to forestall the like of this, we '11 take a regular no^bite on the finished denture to see for sure about it. If it proves, all is well.

But it can't be much wrong; nothing that can't be corrected. So, if needs be. we '11 cor- rect it. And here is the way we '11 do it. We '11 trace a little very thin smidgen of plaster on top of the lower teeth and take an-
