    suture through the tip of the tongue to one side of the septum, by means of which you draw the organ out of the mouth, and to the side opposite to that on which you intend to divide the nerve. You now see the lingual gustatory standing out as a firm band beneath the mucous membrane, and passing forwards and inwards from the point of origin of the superior con- strictor from the jaw to the side of the tongue. Pass a sharp-pointed hook under the nerve so as to fix it. Divide the mucous membrane over the nerve for about half an inch, so that you can see it readily, and then pass an aneurism needle beneath the nerve, and withdraw the sharp hook. The nerve may now be easily stretched, or a portion of it may be removed. Moore's Method of Dividing the Lingual Nerve. Steps of the Operation. A gag is fastened in the mouth and the tongue is pulled upwards, forwards, and to the opposite side. Make an incision with a curved bistoury in a line from the last molar tooth to the angle of the jaw, dividing mucous membrane, beneath it a few fibres of the superior con- strictor, and the anterior margin of the internal pterygoid, with twigs of the tonsillar artery. Should the nerve not have been divided by this incision, it can be felt by the finger beneath the margin of the alveolus, where it can be divided with the small artery accompanying it. An incision down to the bone in the line given, and about three-quarters of an inch loDg, must divide the nerve.
