The Court of Arches.
This court takes its name from Bow-church, which was originally built upon arches, and in which it sat for the dispatch of business. It is the highest court under the jurisdiction of the archbishop of Canterbury. Here all appeals are directed in ecclesiastical matters within the province of Canterbury. The judge of this court is styled the dean of the arches, because he holds a jurisdiction over a deanery in London, consisting of parishes, exempt from the bishop of London's jurisdiction. The officers under this judge are, an examiner, an actuary, a beadle or crier, and an apparitor; besides advocates, and procurators, or proctors.
