[In the Hunterian MS. the following tractate is ascribed to Ibnu'l ‘Arabī, d. 638 A.H. = 1240 A.D. In one of the Berlin MSS., however, it is called Risālatu'l Balbānīyah, by Muḥammad al Balbānī (Ahlwardt, 3, 250); in another Suyūṭī is given as the author (Ahlwardt, 1, 830). In the British Museum MSS. (Arabic Catalogue, No. DCCCLXXXI, ix, and Supplementary Catalogue, No. 245, x) the author is given as Auḥad al Dīn ‘Abdallah al Balyānī, d. 686 A.H. These MSS. have been used in the Translation. The Librarian of the Royal Library, Berlin, most kindly sent the two mentioned above (as well as a third imperfect one) to the care of the Glasgow University Librarian.]
