Those rolls that may properly be termed _Records of Assize_ commence 6 Richard I., and end with the reign of Edward IV. In the B. M. are many MS. volumes of _Placita Itinerum_ pertaining to different reigns and different counties. In 1818 the Record Commissioners published an important folio volume, entitled _Placita de Quo Warranto temporibus Edw. I., II., III._, which forms an interesting sequel to the Hundred Rolls. The Hundred Rolls, as already mentioned, gave a great mass of sworn information as to abuses. Those persons thus charged were summoned to answer “_Quo Warranto_” such and such things were done or left undone? or by what right such and such manors, etc., were held? This volume contains a full transcript of the roll of the pleadings in answer to these summonses, and the judgments thereon. Its utility in manorial history cannot be exaggerated, as the descent of the manor is often traced back in these pleadings to the time of John or even earlier. The rolls are arranged under counties, and include the whole of England, with the exception of the palatinate of Durham. The earliest records of the _Court of Chancery_ are of the 17th year of Richard II., the previous documents having been destroyed in the Wat Tyler rebellion. There are no petitions extant to the Chancellor of the reign of Henry IV., and but few of Henry V., but from the beginning of the reign of Henry VI. they seem to have been kept with much regularity. Calendars of the Chancery proceedings of the reign of Elizabeth were published in three volumes folio, 1827-32. In the introduction to this work are many examples of the earlier proceedings of that court from Richard II. downwards. It is hardly necessary to add that the bills of complaint, and their answers, filed in this court, often contain abundant information as to manorial descent. Numerous MS. volumes of indexes to Chancery proceedings are at the service of the searcher in the P. R. O.
