Corsned \Cors"ned\ (k?rs"n?d), n. [AS. corsn?d.] (AS. Laws)
   The morsel of execration; a species of ordeal consisting in
   the eating of a piece of bread consecrated by imprecation. If
   the suspected person ate it freely, he was pronounced
   innocent; but if it stuck in his throat, it was considered as
   a proof of his guilt. --Burril.
