The school of Saint-Victor, under the abbey, conferred the licence in its own right; the school of Notre-Dame depended on the diocese, that of Ste-Geneviève on the abbey or chapter. The diocese and the abbey or chapter, through their chancellor, gave professorial investiture in their respective territories where they had jurisdiction. Besides Notre-Dame, Ste-Geneviève, and Saint-Victor, there were several schools on the "Island" and on the "Mount". "Whoever", says Crevier "had the right to teach might open a school where he pleased, provided it was not in the vicinity of a principal school." Thus a certain Adam, who was of English origin, kept his "near the Petit Pont"; another Adam, Parisian by birth, "taught at the Grand Pont which is called the Pont-au-Change" ("Hist. de l'Univers. de Paris," I, 272).
