It differs from his, and from all the pretended amendments of his, as a new map, drawn from actual and minute surveys, differs from an old one, compiled chiefly from others still older and confessedly still more imperfect.

He who makes a new grammar, does nothing for the advancement of learning, unless his performance excel all earlier ones designed for the same purpose; and nothing for his own honour, unless such excellence result from the exercise of his own ingenuity and taste.
