frigidarium of the baths are the remains of the altar to Jupiter found under Notre Dame, a statue of the Emperor Julian, and many a relic of Roman Paris. [Illustration: TOWER AND COURTYARD OF HOTEL CLUNY.] The abbots' delightful old mansion is filled with a rich collection of mediæval statues, altar paintings, wood carvings, ivories, reliquaries, stained glass, tapestries (among them the Lady and Unicorn series, the finest ever wrought), embroideries and textile fabrics, enamels and goldsmiths' work--all of wondrous beauty and interest. The rooms themselves, with their fine Renaissance chimney-pieces, where on winter days wood fires, fragrant and genial, burn, are not the least charming part of the museum. Many of the objects (about 11,000) exhibited are uncatalogued, and the old catalogue, long out of date, might well be classed among the antiquities. South of the Cluny are the vast buildings of the new Sorbonne, the modern University of Paris, where some 12,000 students are gratuitously taught. The vestibule, grand staircase and amphitheatre are of noble and impressive architecture, and adorned with mural paintings, among which Puvis de Chavannes' great decorative composition in the amphitheatre is of chiefest interest. The paintings of the vestibule illustrate scenes in the history of the University of Paris. Of Richelieu's Sorbonne, the chapel alone exists to-day: all the remainder has been swept away, together with the north cloister and church of St. Benoist, where François Villon assassinated his rival Chermoyé. We are now on Mont St. Genevieve, crowned by the Panthéon, below which, at No. 14 Rue Soufflot, an inscription marks the site of the Dominican monastery, where Albertus Magnus and St. Thomas Aquinas taught. To the north is the extensive library of St. Genevieve, on the site of the Collége Montaigue. Behind are the church of St. Etienne du Mont the burial-place of Racine and Pascal, with its beautiful _jubé_, or choir screen, and the Lycée Henri IV., enclosing the tower of Clovis, all that remains of the fine old abbey church of St. Genevieve. Hard by is the Rue Descartes, where stood the college of Navarre, which was demolished to give place to the Ecole Polytechnique. Farther south, the Rue de Navarre leads to the ruins of the great Roman amphitheatre. [Illustration: OLD ACADEMY OF MEDICINE.]
