    Ash's Improvements in the Manufacture of Artificial Teeth. I furnish each tooth with projections and pins in place of one of these only, as heretofore. Figures 1 2, and 3, of the annexed Drawing, show respectively a back view, side view, and horizontal section of a tooth so constructed, a is the ridge or projection, and b, b, are metal pins inserted into the substance of which the 5 tooth is composed before it is fired; Figures 4, 5, and 6, show similar views of another tooth, in which two projections a, a, are employed, one on each side with a single pin b between them. The Figures 7 and 8 show other teeth of slightly modified form. In witness whereof, I, the said George Claudius Ash, have hereunto 10 set my hand and seal, this Tenth day December, in the year of our Lord One thousand eight hundred and fifty-nine. G. C. ASH.
