“ Dugal was educated at the school of Chanonry and the universities of Aberdeen (where he graduated M.A.) and Paris. On his return to Scotland, according to George Mackenzie (1669–1725) [q. v.] , he was installed a regent in the university of Aberdeen, ‘with the unanimous applause of the whole masters of the University.’ Of this appointment there is no mention in the records of the university, which, however, are very imperfect for the sixteenth century. ”
