Some months ago I described in the pages of this journal1 a duodenal tube for infants. This tube was introduced by mouth into the stomach, and then passed through the pylorus into the small intestine. This result was readily accomplished, the tube taking about one-half hour to pass the pylorus. The radiographs which accompanied this article showed conclusively that the end of the tube lay in the duodenum, and was not merely curled on itself within the stomach cavity. This duodenal tube. in brief, consisted of soft rubber tubing with a silver-plated, perforated leaden ball at the end, and was a modification of the Gross duodenal tube used for adults. By means of this simple device, I was able, after some practice, to gain access to the duodenum in infants in almost every instance, and gradually acquired increased facility in its use. This was, I believe, the first conclusive
