This paper embodies the result of eight years' study of those anomalies of the digestive tract susceptible of roentgen demonstration. At various times Drs. Samuel Schechter and Jerome A. Marks have collaborated in this research. The material used for this study comprises a consecutive series of 3,000 private patients complaining of digestive disorders, approximately three fifths of whom had test meals and roentgen surveys in addition to the routine history and physical examination.
