To the Editor.
—This is merely in reply to the letter you received from Dr. Kartch concerning the recent publication of my paper in the Archives. Dr. Kartch has very exactingly defined the various probes he has introduced, which undoubtedly serve his purposes most adequately. He was obviously bothered by the same clinical problems we have encountered with the conventional Worst instument, and was prompted to make his specific modifications. Unfortunately, the dimensions of the instrument proposed in my article were not correctly quoted. The probe was modified to a circle of 13 mm rather than 9 mm as stated. The eye in the instrument was not a French eye, but a regular eye to accommodate the tubing cited in the article. It is emphasized that the instrument is to be used in adults and not in children, which becomes obvious viewing the actual correct dimensions of the instrument.
