    • Unascribed question on the Elenchi by an author Sten Ebbesen has called 'The Englishman'[1]. As 'Willelmus vocor' is given as an example of a congruous expression, we may infer that the author's name was 'William'. The version of these questions in the Oxford Oriel 33 has on the first leaf a note that these quires were given by William de Walcote. So it is possible that the Elenchi may be connected with an Englishman who was a fellow of Merton from 1291-1308. There is a transcription of questions 21 and 22 in Braakhuis 1981. (1r-24v)
