Detailed instructions were given for the management and custody of their chirographs, and other matters affecting Jewish residency and practise. By the beginning of 1240 de Criol was Constable of the Tower of London, and he held the position until the middle of 1242, latterly with the assistance of Walter de Gray. Humphrey de Bohun succeeded him as Sheriff in Kent. In the vacancy following the departure of Edmund Rich, his keeping of the archbishopric was assisted by John Maunsell.
