On the 30th he wrote to me that he had got his papers into order and hoped to begin that day. But the same letter told me of the unsettlement thus early of his half-formed Paris plans. Three months sooner than he designed he should be due in London for family reasons; should have to keep within the limit of four months abroad; and as his own house would not be free till July, would have to hire one from the end of March. "In these circumstances I think I shall send Charley to King's-college after Christmas. I am sorry he should lose so much French, but don't you think to break another half-year's schooling would be a pity? Of my own will I would not send him to King's-college at all, but to Bruce-castle instead. I suppose, however, Miss Coutts is best. We will talk over all this when I come to London." The offer to take charge of his eldest son's education had been pressed upon Dickens by this true friend, to whose delicate and noble consideration for him it would hardly become me to make other allusion here.
