A tribunal of special jurisdiction, held before the chancellorof the duchy, or his deputy, concerning all matters of equity relating to lands holden ofthe crown in right of the duchy of Lancaster; which is a thing very distinct from thecounty palatine, (which has also its separate chancery, for sealing of writs, and thelike.) and comprises much territory which lies at a vast distance from it; as particularly avery large district surrounded by the city of Westminster. The proceedings in this courtare the 6ame as were those on the equity side of tlie court of chancery, so that itseems not to be a court of record ; and. indeed, it has been holden that the court ofchancery has a concurrent jurisdiction with the duchy court, and may take cognizanceof the same causes. The appeal from this court lies to the court of appeal. Jud. Act1873,
