To the Editor:
—In The Journal, April 8, is an article entitled, "An Efficient and Time-Saving Method of Tying the Square Knot." In the South Carolina Medical Journal, October, 1909, appeared an article in which I described a method of tying knots identical with the one described by Drs. Castle and Ryfkogel. The maneuvers are reversed, however, that is to say, the first turn of their knot is brought down by my second maneuver, etc. Their description also refers to carrying out these maneuvers with both hands simultaneously in order to tie the friction knot. Strange to say, I also anticipated them in describing this one.
