Demonstrates with examples the calculation of sums involving fractional numbers and square roots. Extensive marginal notes on a few leaves (p. 20-35).

Unbound copy of the story of the People of the Cave, known in other traditions as the Seven Sleepers.

The final leaf is smaller paper (155 x 130 (140 x 110) mm); the recto of that leaf and the previous half page is an addition in a different hand with the verso of the final leaf written in Persian.
