To the Editor:
—The brief article concerning the Chemistry of Barbital and Its Derivatives (The Journal, May 30, p. 1869) by Collins and Leech has helped me to freshen my chemical knowledge. At the same time, footnote 12, concerning the genesis of the word "Veronal," revived the memory of my beloved teacher Freiherr von Mering, who introduced me to the field of internal medicine in the years of 1904 to 1907.At that time von Mering was extensively experimenting at his university hospital at Halle-Saale with a new narcotic, "Veronal," discovered by him and Emil Fischer. Every semester he proudly told us how he happened to call this child of his brains "Veronal." He was on a vacation trip to Italy and the train had stopped at Verona, when a telegram from Emil Fischer was handed to him informing him that he had succeeded in the synthesis of Mering's compound.
