The manuscript is written in a hand of medium size and generally angular in appearance; another takes over in places at folios 4 verso-5 verso.

The contents are as follows.

On Isidore’s commentary on Aphorisms of Damascenus, cf. Adv.MS.72.1.13, folio 1 recto, column a, line 1. Beginning (acephalous) ‘...rainig a les cuisli ⁊ da tucaid leigheas’ = Adv.MS.72.1.13, folio 8 verso, column b, line 1. First complete section beginning ‘Cum nulla de quo ccon inter aqu[a]m et calor[e]m na[tura]lem’. Ends incomplete ‘⁊ uair ele ona hanbai(nne)’ = Adv.MS.72.1.22, folio 6 recto, column b, line 20, in section beginning ‘Quodcumque membrus suscep[er]it detrim[e]ntum’. There are two lacunae due to the loss of a bifolium, so the remainder relates to the printed text of Damascenus (1514 edition) as follows. Folios 1 recto-2 verso: Damascenus folios 31 recto, column b, line 44-31 verso, column a, line 38. Folios 3 recto-4 verso: Damascenus folios 31 verso, column b, line 8-31 verso, column b, line 32.

The usual authorities are cited. (Folio 1 recto, column a, line 1.)
