A severe and obstinate menorrhagia, dependent on this cause, was successfully treated by Breslau with an intra-uterine injection of equal parts of liquor ferri (Bavarian) and water; it was made through a catheter, left only one minute and then withdrawn (1858). This was one of the earliest cases of the kind, and illustrates a method which I have several times employed with advantage; but a more modern and often curative practice is to scrape the surface of the lining membrane with a curette.
