On one of them in particular it is necessary to dwell for a moment or two, because persons unacquainted with the early history of law will not be easily persuaded that a principle, of which modern jurisprudence has very slowly and with the greatest difficulty obtained the recognition, was really familiar to the very infancy of legal science.
