of the principal are : the Coliseum or Amphitheatre of Titus, 560 feet long, 

 472 broad, 154 high, capable of seating 80,000 persons ; the Column of 

 Trajan, 141 feet high, 12 feet thick, composed of 34 blocks of marble ; the 

 marble column of Antonine, 117 feet high; eleven obelisks (the largest 115 

 feet high, 9 feet thick, of red granite) ; the aqueducts, of which three still 

 supply the city with water ; the Baths of Caracalla, Diocletian, and Titus ; 

 the Pyramid of Cestius, 126 feet high (with the Protestant burying-ground 

 in front). The subterranean passages called Catacombs, and extending to a 

 great distance under ground, are very interesting ; originally stone quarries, 

 they were subsequently used as burial-places and places of worship. Rome 

 has numerous beautiful fountains, the finest of which are the Fontana Trevi 

 or Vergine, Fontana di Tritone, Fontana dell' xAcqua Felice, and the spring on 

 the Piazza Navona. Among the educational institutions are the University 

 and the Collegio Romano, with an observatory and a botanic garden. The 

 chief among charitable institutions are the immense Hospital of the Holy 

 Ghost, and the Hospital of St. Michael, for 230 old men, 100 women, 480 

 boys, and 520 girls.
