From the Secundaria we pass to a fourth title, namely, Secunda Philosophia, which appears in two manuscripts of the Staats- und Hof-Bibliothek at Munich. A fifth designation is found in a manuscript, nr xcv, of Corpus Christi college, Oxford, dating, according to Coxe's Catalogue, from the thirteenth century: 'Gulielmi de Conchis, alias Shelley, Universalis Philosophiae Libri III. per modum dialogi,' &c.

It is also known that s objections were raised to a work of William of Conches, entitled the Philosophia, which objections are substantially the same with those enumerated in the following paragraph of the Dragmaticon. I have inserted in the margin the corresponding places in the Philosophia.
After announcing the subject of his treatise William proceeds:
t Est tamen de eadem materia libellus noster qui Philosophia inscribitur, quem in iuventute nostra imperfectum, utpote imperfecti, composuimus; in quo veris falsa admiscuimus, multaque necessaria praetermisimus. Est igitur nostrum consilium, quae in eo vera sunt hic apponere, falsa damnare, praetermissa supplere. Falsa vero illa quae contra fidem catholicam nobis in eo videntur esse, ante auspicium dictionis, nominatim
