(1) ‘Commentarii in octo libros Physicorum Aristotelis’ (302 leaves), beginning ‘Prætermittemus et excellentiam ...’; (2) ‘Commentarii in libros Aristotelis de cœlo’ (30 leaves); (3) Commentarii in duos libros de generatione et corruptione’ (35 leaves); (4) ‘Commentarii in libros de anima’ (90 leaves); ‘Commentarii in omnes libros metaphysicorum Aristotelis’ (37 leaves), ending ‘... ab ipso rerum authore abducamur. Cornelius Lery’. The tracts are separately paged. At the end of the volume is inserted a printed leaf containing ‘Conclusiones ex universa philosophia’. ‘Has conclusiones deo favente propugnavit Cornelius Lery Hibernus Aghideoensis in collegio Rhedonensi Soc. Jesu ... Aug. MDCXXXV’. The present volume seems to contain many of these disquisitions. Lery’s name occurs at the beginning of the volume, with the date 1639. See also MS Ii.04.32.
