This Society published in vol. lxxii of Archaeologia an illustrated description of the almost complete series of the seals of the bishops of Durham, from William of St. Calais (1081) to Cuthbert Tunstall (1559), preserved in the treasury of the dean and chapter of Durham. This paper with the ensuing catalogue is an attempt to record the seals of later date belonging to the see and to the cathedral church of Durham, up to the abolition of what remained of the palatinate powers of the bishops in 1836. The writer thought that this would be a comparatively easy task but it has not been so, for after an exhaustive search in all likely places, the result has been disappointing; examples have been difficult to find, some of the bishops are not represented at all and others only by their great seals in chancery. The only examples of episcopal seals of dignity which have been found later than that of Barnes (pi. xiv, no. 2) are that of Cosin (pi. xvi, no. 3) and those of Trevor, Egerton, and Barrington (pi. xvii).
