"'Until the age of four years my daughter was perfectly healthy, when, at the commencement of winter, she was attacked by cough and wheezing on her chest, which gave the idea that her lungs were affected. Leeches were applied, and medicine given with little effect. She continued to look very ill, and became extremely peevish and inactive. In the spring she was suddenly seized by a pain in her left knee, which rendered her quite lame. The complaint was pronounced to be white swelling. One of our first surgeons assured me the attack was of a most acute nature, the joint of the knee being considerably enlarged, and the suffering very great. By steam-baths and leeching the inflammation was in some degree subdued, and mercury was used in various ways, internally, and externally. In a week or ten days the violent pain subsided, but she could not bear the limb to be moved in the slightest manner. In that state the child continued for eighteen months, during which she had three acute attacks similar to the first, which were got under in the same manner, after each attack the limb became more contracted, and the constitution was evidently sinking, although wine, porter, and fresh meat, etc. etc., were allowed, in order to keep up her strength, but they did not succeed. She was at the sea-side for the benefit of the bathing, which appeared to strengthen her more than anything else, when I learned something of the water system from Captain Claridge's book, and subsequently from himself. At first, I must confess, I was rather startled at the idea of trying such an experiment on my child, but, as every thing else had failed, I made up my mind to go to Gräfenberg and put her into the hands of Mr. Priessnitz. In the beginning of September he commenced with her, giving her at first two packings up and a tepid bath, and one knee-bath during the day, and compresses on the knee and body. He desired that she should have crutches, and try to move about as much as she could without hurting herself. She continued the same treatment during the ensuing winter, during which she had a constant rash on her entire leg, and subsequently several gatherings on and round the knee, none on any other part of her body. In the spring she commenced the cold bath after the packing up, and the douche bath. Her strength increased rapidly, her looks became quite healthy, and her appetite excellent. The appearance of the knee was very variable until the end of the summer, when it diminished considerably in size, and she could bear to have it moved without any annoyance; but about Christmas it became suddenly nearly as bad as ever it had been. All cure was then stopped, except one packing up and tepid bath, and the knee compresses were changed every quarter of an hour. The inflammation and pain were soon got under, but she continued the slight cure until the spring, when she commenced the packing up and cold bathing twice a day--douche-bath
