Also, if a clerk in holy orders, an alderman, or a messenger, be killed by some mischance, which God forbid, double amends will be paid, i.e., twenty marks of silver; but if another be killed, amends will be made with ten marks of silver; but a man's servant will be atoned for by three marks of silver; the wounding of a freeman will be atoned for by the payment of two marks of silver; the wounding of a serf with half a mark. He who has slapped another will pay half a mark of silver.
