This Carron oil can be prepared in a very simple way. It consists of equal parts of olive oil and lime-water. Olive oil, or salad or Lucca oil, is the oil best suited for the purpose; but if not easily obtainable, linseed oil answers the purpose very well. Lime-water can be easily made by any one, if it cannot be procured otherwise. About a teaspoonful of the lime used by builders—if the purer kind is not obtainable—added to a pint of water and well shaken, is all that is required. It is then allowed to settle, and the water when required is drawn off without disturbing the sediment at the bottom. Pour the oil on the lime-water, stir or shake well, and the mixture is ready for use. It is poured freely between two folds of lint, or the lint dipped in the mixture; the lint applied to the wound, and held in position by a bandage. The wound may be dressed twice a day; but in dressing, the wound should be exposed to the air the shortest possible time. If the lint adheres to the wound, it must not be pulled off, but first moistened thoroughly with the oil, when it comes off easily. In some cases, it is not advisable to remove the lint. Under such circumstances, the best way to proceed is to lift up one fold of the lint, drop the oil within the folds, replace the fold as before, and secure the bandage. Carron oil is one of those things that no household should be at any time without. Considering the simplicity of the cure, how easily olive oil and lime-water can be obtained, let us hope that for the sake of relieving even a few minutes’ pain, no reader of this paper will be in the future without a bottle of Carron oil.
