_Other Tumours._ I have had to administer chloroform during the removal of several large and deep-seated tumours of the face, situated just in front of the ear, over the parotid gland, with which some of them were thought to be connected. These operations were generally extremely difficult and tedious, owing to the necessity of avoiding the division of the branches of the facial nerve which passed over the tumour. When the branches of the facial nerve are touched with the forceps, or back of the scalpel, during these operations, the muscles of the face to which the branches are distributed contract very freely, at a time when the patient is perfectly insensible. Mr. Stanley, Mr. Fergusson, and Mr. Tatum, are amongst the surgeons whom I have assisted in the removal of tumours of this kind. I have memoranda of 41 tumours situated behind the angle of the jaw, in the removal of which I have exhibited chloroform. These tumours, which mostly consisted of diseased lymphatic glands, were often very deep-seated, passing near to the carotid artery, and it was necessary on that account to keep the patient quite insensible, to prevent his flinching during the operation. The greater number of these tumours were removed by Mr. Fergusson. Seventy-one of the tumours of the removal of which I have notes, are stated to have been of the encysted kind. Sixteen of them were situated on the eyelids, sixteen on the scalp, three or four in the orbit, several in front, or at the side of the neck, and the rest in different parts of the body. I have memoranda of 66 fatty tumours which were removed from different parts of the body. Some of them were of great size; one weighed fifteen pounds. One which Mr. Fergusson removed in 1855 from the arm of a lady, the patient of Messrs. Maurice and Harris of Reading, was situated beneath the biceps muscle, and weighed two pounds six ounces and a half. The diagnosis of it was very difficult. The fatty tumours were easily removed, except in a few instances, in which the fat was infiltrated in the surrounding tissues. I have notes of the removal of 87 other tumours of various kinds, as fibrous, scirrhous, epithelial, melanotic, fungoid, etc.
