The diseases to which this remedy is now applied in Germany are numerous and very different. Fevers, even of the most inflammatory kind, are said to yield to it. Pure inflammations of vital organs are fearlessly submitted to it. The first case related by Dr. Engel, is one of pneumonia, well marked, in a young girl who had been exposed to a current of cold air after violent exercise in the heat of the day. Dr. Weiss ordered her to be enveloped in a blanket, wet with cold water, and then other blankets over the wet one, with plenty of cold water to drink. Some amelioration of the symptoms followed; but in two hours they were again intense. Two foreign physicians accompanied Dr. E. to the bed-side of the patient, and prognosticated a fatal termination unless she were bled, and the cold water treatment declined. Dr. E. with the greatest confidence, ordered the blanket to be again wetted with cold water. This second application was followed by increase of the burning heat, and also by delirium. Notwithstanding the remonstrances of the foreigners, Dr. E. was still firm in his purpose—and ordered the wet blankets to be applied every half-hour. No change took place till after the sixth application, when the kidneys acted copiously. The seventh application was followed by diminution of the thirst and heat—the patient became more tranquil—began to perspire—and fell into a short sleep. The perspiration continued copious for twenty-two hours, and was kept up by the drinking of large quantities of cold water. The perspiration having ceased, the patient was put into a cold half-bath (slipper) where the respiration became more free. On being taken out and covered over she perspired copiously. The wet blankets were now applied only twice a day, with an occasional half-bath. On the fifth day she was well. (Weiss.)
