    5 10 15 20 25 BO 35 Specification. A.D. 1869,—N° 317. n O Harris’ Improved Method of Making Palates for Artificial Teeth. time to time and at all times thereafter during the term therein expressed, should and lawfully might make, use, exercise, and vend, within the United Kingdom of Great Britain and Ireland, the Channel Islands, and Isle of Man, an Invention for “ Ax Improved Method of Making Plates or Palates for Artificial Teeth,” upon the condition (amongst others) that I, the said Alfred Ellis Harris, my executors or administrators, by an instrument in writing under my, or their, or one of their hands and seals, should particularly describe and ascertain the nature of the said Invention, and in what manner the same was to be performed, and cause the same to be filed in the Great Seal Patent Office within six calendar months next and immediately after the date of the said Letters Patent.

Now I obviate this by cutting away the parts of the plates which correspond to the palate or the bottom of the lower jaw where the tongue would naturally rest in the act of tasting, and by inserting in the space so cut away a piece of perforated platinum of exactly the same shape as the piece cut away, and consequently filling up its place entirely. In my Provisional Specification I stated that I arrived at a similar result by a second process of merely perforating the “ plates,” and also by a third process of cutting away the plates as in the first process but
