New York, May 25, 1914.
To the Editor, Archives of Internal Medicine:
—In the article printed in your valuable journal for March, 1914, on Ulcus Ventriculi, by myself and Dr. I. W. Held, I find the quotation from the article of J. Kauffman entitled, "Mangel an Magen-Schleim," from the Archiv für Verdauungs-Krankheiten, 1907, p. 616, to be incorrect. The first sentence reads that in hyperacidity the mucus in the stomach is increased. J. Kauffman found that in cases in which there is a diminution in the normal mucus of the stomach there is pain simulating hyperacidity, although the acidity is normal. On that he bases his assertion that silver nitrate is beneficial in cases of irritation of the stomach in which the mucus is diminished.M. H. Gross.40 East Forty-First Street.
