During the course of my 1953–4 tour in Arabia, I was able to see a great many new MSS, mostly of specifically South Arabian content, amongst which for example was a rare early copy of Ibn Samurah's 1E6C;abaḳāt, the same MS also containing what appears to be an unknown treatise on the grammatical scholars of Basrah and Kūfah. A photocopy of this MS is now in the Library of the School, and a brief description is in the Madjallat al-Makhtūṭāt al-‘Arabīyah, n, 2, p. 341. Fu'ād Saiyid of the Dār al-Kutub has recently published an edition of the said Ṭabaḳāt.
