To the Editor:
—In The Journal, September 30, Lyon and Bartel describe a new type sigmoidoscope. They object to the seven-eighths inch diameter of the Tuttle and Lynch instruments as being too large, and could get only a short Axtell with a smaller diameter. Evidently they are not acquainted with Yeoman's sigmoidoscope, made by Wappler of New York. I have and now use a Yeoman's instrument with a barrel of five-eighths inch diameter, and also one with a three-eighths inch diameter for "nervous patients" and children. The light is placed at the butt of the instrument and is of a substantial type, and a lens window which does not blow off with inflation is also attached. I have found both light and window so satisfactory under all conditions that I have had it attached to both a proctoscope and an anoscope, the latter of the Hirschman model.
