On March 27, 1897, whilst eating some soup, [J.W.] aspirated a bone. This accident was followed by attacks of violent cough and dyspnoea, which, however, became gradually less… On direct laryngeal examination by mean of Kristein’s spatula, the patient being seated with his head strongly deflected to the left, I saw in the right principal bronchus a white mass. On the following day I introduced, under cocaine anaesthesia, a straight tube of 9 millimeters diameter and of 25 centimeters length through the larynx and the trachea until I came near the foreign body. The curvature of the trachea was thus removed, and the foreign body could be seen distinctly. I had great difficulty in catching hold of the foreign body, using a pair of slender forceps which had specially and quickly been made. The difficulties were great, as at that time…I was still without the necessary practice which enables one to look easily, and even more to operate, through long tubes. Eventually I succeeded in catching the bone and in extracting it. The patient was able to return home the following day.
