The Treatment of Fish Skin Disease or Ichthyosis

Probably incurable; but the sufferings incident to the disease can be very greatly mitigated by warm, alkaline baths and unguents. Use about three ounces of soda or borax in a full bath tub of water. Bran baths and wet compresses are also useful. Careful attention should be given to the general health.
