The anteriorand lateral nasal extensions h, Fig. 22, may be very much abridged as shown, forthe early trials. This will enable a much easier adjustment in the fitting process tocarry the trial-model back into the throat before lifting it, to bring it forward to itsseating in the cleft. This is especially important in the trial fitting of the central portion i between the cleft, which in the final preparation is mainlycut away, should be left for strength during the trial movements, it being curvedforward, as shown, to obtain a clear view of the pharyngeal wall and muscles during the fitting of the veil. 450 CHAPTER IV.
