Bruise three ounces of fresh squills in a mortar, or four or five ounces
of garlic; and macerate in twelve ounces of vinegar in a slow oven, or
on a hot plate, for an hour; strain off the liquid part, and add to it
treacle or honey one pound. The dose should be three or four ounces in
bad coughs; where there appears great irritation in the larynx, two
teaspoonfuls or one tablespoonful of tincture of opium may be added to
two or three doses. A dose may be given every morning.—_White._
