From The Long Lost Friend:
We are informed by a friend that a sure preventive against this terrible disease, is, to take some soft soap and mix it with a sufficient quantity of pulverized chalk, so as to make it of the consistency of buckwheat batter; keep the chalk moistened with a fresh supply of soap until the wound begins to discharge, and the patient finds relief. Our friend stated to us that explicit confidence may be placed in what he says, that he has known several cases where this remedy has been successfully applied. So simple and valuable a remedy, within the reach of everyone, ought to be generally known.--
