Turnip Poultice.--Part of a raw turnip is grated down to a pulp. As much of this is prepared as will cover the inflamed part. It is put on next the skin, and covered with a soft cloth. All is then tied nicely up in another cloth. In violent inflammation of the knee joint, this is a most valuable soothing application. Placed on discoloured and shrivelled skin, it is marvellously curative. When applied, the patient must be _thoroughly warm_. This warmth must be maintained while the poultice is on, as it has a powerful cooling effect. Typhoid Fever.--_See_ Fever, Typhoid. Ulcers.--An ulcer is an "eating sore": that is, a sore containing matter which eats away the skin and flesh, thereby extending itself, and increasing in depth as well. To stop this diseased process, the virulent matter in the ulcer must be killed or neutralised, and this can usually best be done by means of vinegar or weak ACETIC ACID (_see_), which is most powerfully antiseptic. The only difficulty is to avoid irritating the sore by the application of too strong acid. The treatment by weak acid is very effective, but it must be a fairly prolonged and thorough soaking. Apply a little at a time to the sore. Use warm water if pain be caused. Continue the soaking for even an hour at a time, twice or even three times a day. The wound may be dressed with good fresh olive oil after each soaking. Usually, nothing else will be required, but it must be thoroughly done. In a very severe case, mix in a teacupful of hot water as much saltpetre as the water will dissolve. Add to this a teaspoonful of acetic acid, and use this to soak the sore instead of simple weak acid. Then, if healing does not come, it is probably because rest is not taken, and most likely also because there is deficient vitality in the whole system. Let the treatment with the lotion be given in the morning. Secure rest during the day, and in the evening, for an hour, thoroughly foment the feet and legs up over the knees. Once a week for two weeks give the SOAPY BLANKET (_see_) instead of this treatment, and in the morning rub all over the body with hot vinegar. This powerfully stimulates the vitality of the whole system. Even a very bad ulcer should give way under a careful course of united acid soaking, rest, and this stimulating treatment.
