Carrying out this idea, Laynez, in 1564, promulgated a rule or "Form regarding the acceptance of Colleges." He laid down the conditions, on which alone the Society would take in charge either a Latin School, requiring a foundation for twenty Jesuits; or a Lyceum, with fifty persons; or a University, with seventy.[31] Twenty-four years later, Father Aquaviva drew up a more complete and a final "Form," distributing colleges into the three classes, the lowest, the medium, and the highest. The lowest must have provision made for professing in the departments of Grammar, Humanities, Rhetoric, Languages, and a course of Moral Theology;--fifty Jesuits to be supported. The medium class of colleges consists of those whose founders desire, in addition to all the foregoing departments, a triennial course of Philosophy, which begins each year anew; eighty persons to be supported. The highest class is that of the Studium Generale, or University, in which, besides the above, there are professed Scholastic Theology, Sacred Scripture, Hebrew; one hundred and twenty persons to be provided for. However, the countries of the Indies, as well as the northern countries of Europe, were not, for the present, brought under this ordinance.[32] Thirdly, the locality is to be such that, in the ordinary course of events, there should be no prospective likelihood of a deficiency in the concourse of students, and those of the right kind. As, on the side of the Jesuit Province, its educational forces are kept at least equal to the posts which it has undertaken to fill, so, on the side of the population, the prospect should correspond to this undertaking, and give assurance of filling the courses. Hence it was only in larger cities or towns that Ignatius contemplated the foundation of colleges; as the distich has it, contrasting the different fields of activity chosen by different orders in the Church:-- Bernardus valles, montes Benedictus amabat, Oppida Franciscus, magnas Ignatius urbes. That is to say, "The monks of Clairvaux loved their valleys; the Benedictines their mountain-tops; the Franciscans the rural towns; Ignatius the great cities."
