.⁠—Three letters for me. The first, from the Arnolds, full of delight at the prospect of seeing Laura and me. The second, from one of the gentlemen to whom I wrote on Walter Hartright’s behalf, informing me that he has been fortunate enough to find an opportunity of complying with my request. The third, from Walter himself, thanking me, poor fellow, in the warmest terms, for giving him an opportunity of leaving his home, his country, and his friends. A private expedition to make excavations among the ruined cities of Central America is, it seems, about to sail from Liverpool. The draughtsman who had been already appointed to accompany it has lost heart, and withdrawn at the eleventh hour, and Walter is to fill his place.
