In a very striking case reported by Dr. W. S. Play-fair, a sheet or towels wrung from iced water were almost constantly applied for eleven days, the patient lying on a water-bed kept cold with running water, and having an ice-cap on the head. By these means only could the temperature be kept under 105°. Eventually the patient was saved, Warburg's tincture having some share in the result (British Medical Journal, ii., 1877). Dr. Wiltshire has also reported cases of this disease treated by dry cold, i.e., ice packed in bottles and tins near the patient, with temporary good result under unfavorable conditions. Mr. Knowsley Thornton has found an ice-cap, for application to the head only, very useful in keeping down the temperature for ovariotomy.
