In the autumn of this year he began another story, to be published weekly in "All the Year Round." The letter to Mr. Forster, which we give, tells him of this beginning and gives him the name of the book. The first number of "Great Expectations" appeared on the 1st December. The Christmas number, this time, was written jointly by himself and Mr. Wilkie Collins. The scene was laid at Clovelly, and they made a journey together into Devonshire and Cornwall, for the purpose of this story, in November. The letter to Sir Edward Bulwer Lytton is, unfortunately, the only one we have as yet been able to procure. The present Lord Lytton, the Viceroy of India, has kindly endeavoured to help us even during his absence from England. But it was found to be impossible without his own assistance to make the necessary search among his father's papers. And he has promised us that, on his return, he will find and lend to us, many letters from Charles Dickens, which are certainly in existence, to his distinguished fellow-writer and great friend. We hope, therefore, it may be possible for us at some future time to be able to publish these letters, as well as those addressed to the present Lord Lytton (when he was Mr. Robert Lytton, otherwise "Owen Meredith," and frequent contributor to "Household Words" and "All the Year Round"). We have the same hope with regard to letters addressed to Sir Henry Layard, at present Ambassador at Constantinople, which, of course, for the same reason, cannot be lent to us at the present time. We give a letter to Mr. Forster on one of his books on the Commonwealth, the "Impeachment of the Five Members;" which, as with other letters which we are glad to publish on the subject of Mr. Forster's own works, was not used by himself for obvious reasons. A letter to his daughter Mamie (who, after her sister's marriage, paid a visit with her dear friends the White family to Scotland, where she had a serious illness) introduces a recent addition to the family, who became an important member of it, and one to whom Charles Dickens was very tenderly attached--her little white Pomeranian dog "Mrs. Bouncer" (so called after the celebrated lady of that name in "Box and Cox"). It is quite necessary to make this formal introduction of the little pet animal (who lived to be a very old dog and died in 1874), because future letters to his daughter contain constant references and messages to "Mrs. Bouncer," which would be quite unintelligible without this explanation. "Boy," also referred to in this letter, was his daughter's horse. The little dog and the horse were gifts to Mamie Dickens from her friends Mr. and Mrs. Arthur Smith, and the sister of the latter, Miss Craufurd. [Sidenote: Mr. W. C.
