To the Editor:
—Mr. J. Greig Smith has called my attention to my unintentional misstatement of his views on page 643 of The Journal, for November 1, 1890. I hasten to say, therefore, that a reference to his " Abdominal Surgery " shows that he has clearly stated that floating kidney is always congenital, but movable kidney as a rule is acquired. Very truly yours,1729 Chestnut St., Philadelphia, Dec. 1, 1890.
