To treat the sore, it should be washed twice a day with BUTTERMILK (_see_), and afterwards thoroughly soaked with weak ACETIC ACID (_see_), and dressed with antiseptic lint, or, if that cannot be had, with buttermilk cloths. A buttermilk poultice (_see_ Potato Poultice) may be used. But if no rest can be had, the sore will be extremely difficult, if not impossible, to heal. The second kind of sore, arising from an abscess under the part, or diseased bone or membrane far down beneath the skin, is to be treated on the same principles, using weak acetic acid for the syringing, and buttermilk only for the surface. The method of treatment is such as will secure the contact of the weak acid with _every part_, even the deepest, of the wound. Procure a small pointed glass syringe, which must be kept _thoroughly clean_. The point of this may be inserted into the sore, and care taken that the weak acid penetrates into the very bottom, and thoroughly soaks all the diseased parts. This syringing should be repeated until the wound is thoroughly clean in every part. If pain is set up, the acid is too strong. Syringing with lukewarm water will at once relieve this, and then weaker acid may be used. This treatment may be given twice a day, and the wound properly dressed after it. Attention must be paid in all treatment of sores or wounds to the proper cleansing and boiling of all materials and instruments used. Wash the hands in hot water and M'Clinton's soap, using a nail-brush, before touching or dressing a sore. Boil some soft clean rags for five minutes, and wash the sore with these, using water that has been boiled and allowed to cool to blood-heat, to which a few drops of acetic acid have been added, but not so much as to be painful on the sore. If a syringe is used, boil it before using, and only use boiled or distilled water in all operations. This secures the destruction of the germs (or Bacteria), which are now known as the cause of the inflammation and suppuration of wounds and sores of all kinds.
