To the Editor:—
The idea expressed by the authors in the article entitled "Food Pump: New Approach to Tube Feeding," by Barron, Prendergast, and Jocz, which appeared in The Journal, June 16, 1956, page 621, is not new. The authors have overlooked a previous contribution on the same subject, entitled "Continuous Forced Feeding Pump, a New Approach to Nutritional Therapy" by C. C. Snyder, then of Galveston, Texas, now of Miami, Fla., published in Plastic & Reconstructive Surgery (8:73, 1951). As far as can be determined, these two pumps operate on about the same principle.
