[2635] The titles more often speak of ten treatises, but some of these sub-divide into two or more lesser treatises. Such sub-division and combination also varies in different editions and MSS, and the order of the component treatises also varies. In the edition of 1550, for instance, the work is divided into six parts, of which the first contains what are usually listed as the first five or six of the ten or twelve component treatises. But the order of the edition of 1550 is the same as in that of 1491, while in Arundel 66 the order of the last six treatises is different.

[2637] Some others mentioned are, II, ii, 1, Atezdegoz, Adila, Al-hayat, Astaphan, Arastellus; these are probably indirect citations. Elsewhere Aoma (Haomar) and Aboali (Haly) are mentioned.
