Note Rashed (Les mathématiques infinitésimales II) describes both works included in this manuscript as being part of MS ʿAbd al-Ḥayy 678/55, which, at the time when he consulted it, was a collective volume of 45 ff. in great disorder. It also contained the following works by Ibn al-Haytham (Rashed, Les mathématiques infinitésimales II; Rashed, Les mathématiques infinitésimales V; Rashed, ‘Ibn al-Hayṯam’): Qawl fī Misāḥat al-kura (1r–4v and 13v–14r, now in Abdul Hai = AH 673/50); Qawl fī Tarbīʿ al-dāʾira (10r–11v, 30v, 30r, now AH 674/51); Fī l-Hilāliyyāt (14v–16v, now AH 677/54); Maqāla fī ʿIllat al-jadhr wa-iḍʿāfi-hi wa-naqli-hi (17r–19r, now AH 678/55); Fī Birkār al-dawāʾir al-ʿiẓam = Risāla fī ʿAmal dawāʾir ʿuẓām bi-āla ṣaghīra (29r, 8r–10r), now AH 676/53); Fī l-Marāyā l-muḥriqa bi-l-quṭūʿ (41r–v, 44r, 47r–48v). Apparently the manuscript was restored and split up in six parts (MSS 673/50–678/55) after Rashed consulted it.
