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,
