PREPARATION OF THE SKIN.

The hair over the pubes and the groin of the affected side should be cut rather close and then the parts scrubbed with a solution of green soap. A small amount of a forty per cent. solution of formaldehyde may be added to the soap solution as this agent is a very powerful antiseptic.

Soap solution.

Formaldehyde solution, one dram (40%).

Green soap, four ounces.

Dilute alcohol to make one pint.

The dilute alcohol is made up of equal parts of ninety-five per cent alcohol and water.

After the parts are thoroughly scrubbed with this solution the soap should be removed with moist compresses and then the parts mopped with a solution of seventy per cent alcohol. Finally the field of operation should be flooded

with ether as this agent is an effective antiseptic and also acts as a solvent for any greasy matter not removed by the soap.
