Barbiton, an ancient instrument of music, mounted with three, others say seven, strings; much used by Sappho and Alceus, whence it is also denominated Luteum.

Barbules, or Barns, in farriery, the knots or superfluous flesh that grow up in the channels of a horse's mouth; that is, in the intervals that separate the bars, and lie under the tongue. These, which are also called barbers, obtain in black cattle as well as horses, and obstruct their eating. For the cure, they caulk the beast, take out his tongue, and clip off the barbles with a pair of scissors, or cut them with a sharp knife; others choose to burn them off with a hot iron.
