Twelve years ago Pusey expressed to me the opinion that sulphur in volatile form incorporated into an ointment would be more useful in dermatologic conditions than precipitated sulphur.1 After using such an ointment for ten years, I am able to verify this opinion. The volatile sulphide most used by me is solution of sulphurated lime N. F.
The ointment which I have found most convenient has the following formula:
The wool fat and petrolatum are melted and thoroughly mixed. When the mixture is cool, the solution of sulphurated lime is worked in. Pulverized camphor is next incorporated. The preparation has a deep yellow color and an odor similar to that of hydrogen sulphide.
This ointment may be used from one-half (for children) to full strength (for adults) in scabies. It destroys the parasites within twenty-four hours. There is seldom any irritation of the skin from the oint
