"You will easily understand, Venerable Brother, the pleasure We felt in what you reported to Us about the College of Stonyhurst in your diocese, namely, that by the efforts of the Superiors of this College, an excellent course of the exact sciences has been successfully set on foot, by establishing professorships, and by publishing in the vernacular for their students text-books of Philosophy, following the Principles of St. Thomas Aquinas. On this work We earnestly congratulate the Superiors and teachers of the College, and by letter We wish affectionately to express Our good-will towards them."
