In January, 1879,1 performed nearly as extensive an opera-tion on a man, aged sixty-eight, removing the lower jaw fromthe right incisors to the left angle, for extensive epitheliomaof the jaw and floor of the mouthy the patient making agood recovery and being in perfect health two years later,but dying with recurrence of the disease eventually {Lancet,November 20, 1880). In the cases of recurrent epithelioma of the lip, whenthe disease shows itself in the submental glands, whichbecome adherent to and implicate the bone, it is possible togive relief, for a time at least, by sawing out the portion of Fig. bone involved, as I did in an old man in May, two instances I have sawn off the chin only, withoutbreaking the line of the alveolus, or opening the cavity ofthe mouth. Tig. 175 shows the first patient ou whom I per- 376 MALIGNANT TUMOURS OF LOWER JAW. formed the operation, and tlie details of the case will befound in the Appendix (Case XVI.).
