Note 159 — APPENDIX TO CHAPTER IV. PART I. THE NINE AQUEDUCTS IN THE TIME OF FRONTINUS.

An Anglo-Roman company has now (1872) brought the Aqua Marcia (III.) again into Rome at so high a level, that it will supply cisterns at the tops of the houses. At present a number of ingenious contrivances are in use for sliding small buckets of water from the well or reservoir in the courtyard, to the upper windows and galleries round the central courts of the old houses or palaces. These reservoirs, whether large or small, are called lacus by Frontinus and in the Regionary Catalogue.
