Knighthood. The institution of the " Order of the Bath" originated in the custom of the Franks, who, when they conferred knighthood, bathed before they performed the ceremony, and from this habit came the title of the "Knights of the Bath." Henry IV. instituted a degree of knighthood of the Bath, and on his coronation, in the Tower, he conferred the order upon forty-six esquires, who had watched the night before, and bad bathed.
