This term is derived from the two French words _vin aigre_, 'sour wine,' and should, therefore, be strictly applied to that which is made only from wine. As the acid is the same, however it is procured, that made from ale also takes the same name. Nearly all ancient nations were acquainted with the use of vinegar. We learn in _Ruth_, that the reapers in the East soaked their bread in it to freshen it. The Romans kept large quantities of it in their cellars, using it, to a great extent, in their seasonings and sauces. This people attributed very beneficial qualities to it, as it was supposed to be digestive, antibilious, and antiscorbutic, as well as refreshing. Spartianus, a Latin historian, tells us that, mixed with water, it was the drink of the soldiers, and that, thanks to this beverage, the veterans of the Roman army braved, by its use, the inclemency and variety of all the different seasons and climates of Europe, Asia, and Africa. It is said, the Spanish peasantry, and other inhabitants of the southern parts of Europe, still follow this practice, and add to a gallon of water about a gill of wine vinegar, with a little salt; and that this drink, with a little bread, enables them, under the heat of their burning sun, to sustain the labours of the field.
