D., Montreal, SENIOR DBMON8TBATOR OP ANATOMY AND LEOTUBEB ON LARTNGOLOGT, MC GILL UNIVERSITY ; LARYNGOLOGI9T TO TUB MONTREAL GENERAL HOSPITAL. Upon May 30, 1891, I was called in consultation by the late Dr. Georjje Ross to see Mrs. McQ., aged twenty-two years, in reference to marked dyspnoea, evidently due to laryngeal ob- struction, from which she was suffering. The patient stated that she began to be hoarse four months ago, and that this had gradually increased until there was almost complete aphonia. Dyspnoea set in four weeks ago and slowly increased, until within tiie past two weeks it had been so marked as to prevent the patient lying down, and for the past few days any attempt to lie down would bring on an at- tack of suffocation. Within this last-mentioned period— two days — inspiratory stridor has set in, accompanied by depression of the supraclavicular, infraclavicular, and suprasternal regions. The patient is thin and anaemic-looking, is between eight and nine months advanced in pregnancy (primipara) ; her facial expression is that of anxiety ; sits in the upright position all the * Accepted as a candidate's thesis for membership in the American Laryngological Association, May, 1893.

Family and personal histories are absolutely negative re- garding any phthisical, syphilitic, or malignant taint. Laryngoscopic examination revealed a large subglottic tu- mor, occupying so much of the space below the cords as to leave only a very small chink, equal to the size of an ordinary knit- ting needle, between the posterior surface of the tumor and the posterior wall of the larynx, through which respiration is with great diflBculty carried on. The surface of the tumor is of a dusky red color and upon it several small distended vessels are discernible. The movements of the vocal cords are perfectly free and they meet well over the surface of the tumor in the median line. The right vocal cord is congested at its anterior third. I advised preliminary tracheotomy as being at the present moment urgent and necessary in order to relieve the dangerous supervening symptoms of possible suffocation. Consequently, on the following day I performed tracheotomy, being kindly assisted by Dr. Roddick. Chloroform was administered only to incomplete insensibil- ity. There was nothing unusual to note during the steps of the operation, further than that the isthmus as well as the lateral lobes of the thyreoid gland were much enlarged, and coming down from the isthmus to join the transverse innominate vein were three very much dilated veins, each about the size of a goose quill. It was found necessary to ligate the middle one, which lay upon the center of the trachea, the others being held to one side. I decided to open the trachea as low down as possible, because it was uncertain how far down the tumor might extend into the trachea. Upon the introduction of the tube (Durham) the breathing at once became tranquil and easy. Twelve days later, the patient having hitherto progressed satisfactorily, the temperature having never risen above normal, upon consultation with Dr. George Ross and Dr. J. C. Cameron, it was decided that premature labor should be induced, and SUBCHORDAL SPLVDLE-CELLED SARCOMA. 3 with that in view Dr. J. C. Cameron undertook the charge of the cnse. Two days subsequently the patient was delivered of a well- developed female cliild. The influence of this delivery upon the condition of the tumor was striking. Laryngoscopic examination showed that the laryngeal tumor had decreased in size, leaving, consequently, a larger breathing space, and the hypereemia of the right vocal cord which was seen earlier in the progress of the case had completely disappeared, leaving it perfectly white, and when the tracheal wound was closed the patient could breathe more freely, though still the breathing was labored. Three weeks after the confinement the operation for re- moval of the intralaryngeal tumor by means of thyreotomy was undertaken. r In this procedure I was kindly assisted by Dr. Shepherd. Chloroform was administered through the tracheal cannula by Dr. Evans. The site of the of)eration was thoroughly cleansed by means of hot water and soap; the head thrown back over a round pillow. The incision was made in the median line from the upper border of the thyreoid cartilage to the lower border of the cricoid cartilage, continuing the dissection until reaching the thyreoid cartilage, an-'
