For Burns or Scalds
Keep in a bottle, tightly corked, 1/2 oz. of trefoil, and the same of sweet oil; apply with a feather, immediately that the accident has occurred. Linseed or olive oil, applied instantly, will draw out the fire; treacle will have the same effect, and is recommended by some persons, in preference to anything else. Others say that fine flour, applied instantly, is the best thing; as soon as it becomes warm, replace it with fresh. Wadding also laid on the part instantly is good to draw out the fire.
