Editorial note — APPENDIX

Page 21. It is impossible to give separate references to all the authorities which I have consulted in writing this chapter. The work which I have found most valuable—incomparably so—is the Campanien of Beloch, which outstrips both in learning and in judgment all works known to me upon the Phlegræan Fields. It may be said, once for all, that with hardly one exception, the best works upon the region of Naples are by Germans. English scholarship does not appear to advantage. If a man will not read German, he may seek information usefully from Breislak, Topograpia Fisica della Campania (Firenze, 1798). Other useful works are:—Phillips, J., Vesuvius (Oxford, 1869); Daubeny, C. G. B., A Description of Volcanoes (London, 1848); Logan Lobley, Mount Vesuvius (London, 1889); to which should be added the "Physical Notices of the Bay of Naples," by Professor Forbes, in Brewster's Edinburgh Journal of Science, vol. x. All these works treat of the Phlegræan Fields, as well as of Vesuvius.
