This is a summary by Thābit ibn Qurrah (d. 288 AH/901 CE) of
Galen’s treatise On withering (Jawāmiʿ Thābit ibn Qurrah min
kitāb Jālīnūs fī al-dhubūl).
The copy is undated and unsigned, but the general appearance of the
paper (which has been severely water-damaged), the ink, and the
script suggests a date of the 14th century. This is the ending of
the manuscript.
