It is “an ancient English word, and signifies one that is set in the turn, stead, or place of another; and of these some be private * * * and some be publike, as attorneys at law.” Co. Litt. 516, 128a; Britt 2856. One who is appointed by another to do something in his absence, and who has authority to act in the place and turn of him by whom he is delegated.
