There is a semi-business, semi-pleasure little dinner which I intend to give at The Prince of Wales, in Leicester Place, Leicester Square, on Saturday, at five for half-past precisely, at which only Talfourd, Forster, Ainsworth, Jerdan, and the publishers will be present. It is to celebrate (that is too great a word, but I can think of no better) the conclusion of my "Pickwick" labours; and so I intend, before you take that roll upon the grass you spoke of, to beg your acceptance of one of the first complete copies of the work. I shall be much delighted if you would join us. I know too well the many anxieties that press upon you just now to seek to persuade you to come if you would prefer a night's repose and quiet. Let me assure you, notwithstanding, most honestly and heartily that there is no one I should be more happy or gratified to see, and that among your brilliant circle of well-wishers and admirers you number none more unaffectedly and faithfully yours than, My dear Sir, yours most truly. 1838. NARRATIVE. In February of this year Charles Dickens made an expedition with his friend, and the illustrator of most of his books, Mr. Hablot K. Browne ("Phiz"), to investigate for himself the real facts as to the condition of the Yorkshire schools, and it may be observed that portions of a letter to his wife, dated Greta Bridge, Yorkshire, which will be found among the following letters, were reproduced in "Nicholas Nickleby." In the early summer he had a cottage at Twickenham Park. In August and September he was again at Broadstairs; and in the late autumn he made another bachelor excursion--Mr. Browne being again his companion--in England, which included his first visit to Stratford-on-Avon and Kenilworth. In February appeared the first number of "Nicholas Nickleby," on which work he was engaged all through the year, writing each number ready for the following month, and never being in advance, as was his habit with all his other periodical works, until his very latest ones. The first letter which appears under this date, from Twickenham Park, is addressed to Mr. Thomas Mitton, a schoolfellow at one of his earliest schools, and afterwards for some years his solicitor. The letter contains instructions for his first will; the friend of almost his whole life, Mr. John Forster, being appointed executor to this will as he was to the last, to which he was "called upon to act" only three years before his own death. The letter which we give in this year to Mr. Justice Talfourd is, unfortunately, the only one we have been able to procure to that friend, who was, however, one with whom he was most intimately associated, and with whom he maintained a constant correspondence.
