Never have I seen so terrible a sea, and that the packet-boat was not broken up by the force of the waves must have been due to the fact that our time had not yet come. On two or three occasions I thought my last moment was at hand; I leave you to imagine what a terrible experience I had. In ordinary weather the packet by which we travelled makes the voyage from Ajaccio to Marseilles in about eighteen hours; it is said to be the fastest steamer on the Mediterranean. On this occasion it took three days and two nights." 3/15. January, 1853. NOTES TO CHAPTER 4. 4/1. To his brother, from Avignon, 1st August, 1854.
