We come to the regular faculty of the university, the _Professores Ordinarii_. They enjoy the fullest privileges, are appointed for life, and receive beside the tuition-fees regular incomes. They may be elected to the Academic Senate and to the Rectorship, the Rector or Chancellor not being appointed for life, but changing yearly,--the various faculties being represented in turn. He is styled _Rector Magnificus_. The faculties are usually four in number. In several universities, of late, a fifth has been created,--the _Staatswissenschaftliche_, Cameralistic; so that in institutions where both Catholic and Protestant Theology are represented, there are in fact six faculties. The Philosophical Department stretches over so wide a field, that, were it separated into its real divisions, as Philosophy proper, Philology, History, the Mathematical and Natural Sciences, the faculties would extend far beyond the present number. In France, it is divided into a _Faculté des Lettres and a Faculté des Sciences._ The present comprehensive use of the term is but an extension of the Middle-Age division of the liberal arts into the Trivium,--Grammar, Rhetoric, Dialectics,--and the Quadrivium,--Arithmetic, Music, Geometry, and Astronomy,--as expressed in the verse,-- "Lingus, tropus, ratio, numerus, tenor, angulus, astra." The term _Magister Artium Liberalium,_ so often met with, refers to these. Those pursuing these studies were denominated _Artisti._ As the number of studies increased, the name was changed, and the department now includes all branches not ranged under one of the heads of Theology, Law, or Medicine; so that every student, whatever his pursuits may be, if he does not confine himself exclusively to them, will wish to hear one or more courses of lectures in this faculty. The Professors Ordinary and Extraordinary, together with the _Privat-Docents_, form the active force of the German university. In Tübingen are _Repetenten_, who lecture or comment on classical and Biblical writers and form classes in the ancient or modern languages. Those teaching the modern languages exclusively are styled _Lectors_. The title, _Professor Honorarius_, as of Gervinus in Heidelberg, is conferred merely as a mark of honor, the bearer lecturing only when he pleases. To complete this enumeration, it may not be unnecessary to state, connected with each university are masters for riding, fencing, swimming, gymnastics, and dancing, regular places appointed for these exercises, beside access to museums, the university library, scientific collections, etc.
