In this, as in other work pertaining to incision and manipulation of the tissues, scrupulous care must be taken that infection does not occur. This will not occur if blood is not drawn and cleanliness and antisepsis are practiced at all times. Infection occurring in the feet because of the attendant circumstances is often severe. This should be especially remembered. The measures to be taken consist of i. Cleanliness and disinfection of the attendant's hands. 2. Cleanliness and disinfection of the instruments. 3. Cleanliness and disinfection of the part. The hands and forearms up to and above the elbows should be thoroughly scrubbed with soap and hot water where procurable and the latter frequently changed during the process. The brush should be sterile, made so by boiling. Special attention in the scrubbing should be given to the folds and creases of the skin, and to the spaces around and beneath the nails. Rings should be removed from the hands. Lastly, the hands should be scrubbed in seventy per cent. alcohol for five minutes. Instruments should be kept in the case provided for the purpose and well covered with liquid petrolatum or vaseline when not in use to prevent rust. When use is demanded wipe free of oil or vaseline with clean gauze and wash in hot water and soap to remove last vestiges of grease. Knives should not be boiled as boiling tends to dull sharp instruments. Sterilize by placing in a five per cent. a solution of carbolic acid for twenty minutes and then transfer to eighty-five per cent. alcohol.

The part should have been previously cleaned. Apply tincture of iodine three per cent. Allow drying. Then apply alcohol seventy per cent. Iodine is an admirable antiseptic which penetrates the epidermis and fixes the bacteria in the skin.
