Thecase (No. XXXIV.) will be found in the Appendix. The effect of the use of the shields seems to have been,not merely to prevent adhesions between the inside of thecheek and the alveolus, but to re-establish, to a great extent,the sulcus of mucous membrane at the base of the alveolus,upon which so much stress is laid by Professor experience in cases of ruptured perineum, &c., showshow soon mucous membrane is reproduced where it has onceexisted, or even appears on adjacent parts where its presence Fig. gives rise to inconvenience; and there can be no questionthat in this case the mucous lining of the cheek has beenreproduced to a great extent, and particularly near the loweralveolus. EsmarcVs theory, that there must be some portionof old mucous membrane remaining which afterwards be-comes stretched, is certainly untenable as regards this caseat least, for without doubt the whole lining of the cheekand the outside of the alveoli were perfectly raw, owing tothe division of the firm cicatrices. The cause of non-success in former attempts at mechanicalappliances is to be found, I think, in the fact that they have 350 CLOSURE OF THE JAWS. all been directed simply to keeping the jaws apart, withoutany reference to the re-establishment of the mucous liningof the cheek, upon which, as Professor Esmarch says, themovements of the jaw so much depend. That the successin this case depended upon this fact is proved, I think, bythe existence of a firm band in the che
