The open-ing in the palate to be coveredby the plate, in this case, ex-tended from the alveolar borderbackward a little more than aninch, and was about seven-eigliths of an inch in width. The functions of mastication, deglutition and speech, whichwere all very greatly impaired by the opening in the palate andloss of so many of the teeth, were, in a great degree, restoredby the piece here The author would here refer to an obturator, complicated witliartificial teeth, constructed by Mr. Warren Rowell, of New great difficulty to be overcome in this case, accordingto report made of it by Dr. Griscom,* was the want of teeth inthe upper jaw to sustain it, and the great size of tlie opening inthe palate, the vomer and turbinated l)ones having been <le-stroyed. Upon examination, however, iMr. Rowell found thatthe posterior portion of the palatine apertuie was formed, toa consideralde extent, of a semi-cartilaginous substance, possess-ing sufficient elasticity to allow a larger body than the openingto be pushed up through it, and that when so forced up, it wouldbe supported above the aperture by the edge returning to it^original position. This, he hojjcd, would support a lightplate, if the obturator could be so shaped as to rest upon thecartilaginous led;e, after it was introduced.
