Aromatic Vinegar

Mix with a table-spoonful of vinegar enough powdered chalk to destroy

the acidity. Let it settle--then turn off the vinegar from the chalk

carefully, and dry it perfectly. Whenever you wish to purify an infected

room, put in a few drops of sulphuric acid--the fumes arising from it

will purify a room where there has been any infectious disorder. Care

is necessary in using it, not to inhale the fumes, or to get any of the

acid on your garments, as it will corrode whatever it touches.
