The Prerogative Court.
This court is thus denominated from the prerogative of the archbishop of Canterbury, who, by a special privilege beyond those of his suffragans, can here try all disputes that happen to arise concerning the last wills of persons within his province, who have left goods to the value of and upwards, unless such things are settled by composition between the metropolitan and his suffragans; as in the diocese of London, where it is . To this court belongs a judge, who is styled ; and a registrar, who has convenient rooms in his office, for the disposing and laying up safe all original wills and testaments. The registrar also has his deputy, besides several clerks.
 The insolence, carelessness, and total want of common civility that characterises all the members of this office, is too well known; and it is much to be regretted, that a competent power is not applied to place this office on a better footing.
