Among a group of ten mirrors B2864 found together at the corner of Church Street and Watermoor Road in 1926 is a bronze disc 0·053 m. in diameter (fig. 7). During recent treatment of these at the Ashmolean Museum, traces of letters became visible on both sides of it. From these it was evident that the disc had been cut from the second of the two bronze plates forming the certificate of honourable discharge and grant of privileges to a time-expired soldier of an auxiliary regiment. It may be recalled that these tabulae honestae missionis contained on the first of their four pages a memorandum repeating the certified copy of the decree, on the second and third pages this certified copy, ending with the name of the recipient and on the fourth page the names and seals of the seven witnesses which made the document a legal instrument.
