It certainly would be malpractice toextract teeth in this class of cases, be-cause quite a decided forward movementof the entire lower denture and a slightretruding movement of the upper one lower denture in relation to the man-dible, the chin being in normal facialharmony. (See Fig. 24.) My only object in presenting it at thistime is to confirm by it, and by the pic-ture that will follow, in connection withothers that I have shown, what I shallhave to say in an ethnological treatmentof this subject, in regard to there beingevery possible antero-posterior malrela-tion in the positions of dentures as re- Fig. 25.

It consistsmainly in a decided protrusion of the gards the jaws in which they are placed,and also in the positions of the jaws toeach other and to the balance of thebones which form the physiognomy.
