with English literary and political affairs, to complete her "Life." Having once asked Mrs. Chapman to fulfill the task, however, Harriet Martineau was too loyal and generous a friend to remove it from her charge; and Mrs. Chapman, on her side, while continually begging instructions from her subject as to what she was to say, and while doubtless aware that she would not be adequate to the undertaking which had grown so since she accepted it, yet would not throw it off her hands. But her volume is in no degree a record of those last years, which constitute nearly a third of Harriet Martineau's whole life. I have had to seek facts and impressions about that period almost entirely from other sources. My deepest obligations are due, and must be first expressed, to Mr. Henry G. Atkinson, the dearest friend of Harriet Martineau's maturity. It is commonly known that she forbade, by her will, the publication of her private letters; but she showed her supreme faith in and value for her friend, Mr. Atkinson, by specially exempting him from such prohibition. Her objection to the publication of letters was made on general grounds. Her own letters are singularly beautiful specimens of their class; and she declared that she would not mind if every word that ever she wrote were published; but she looked upon it as a duty to uphold the principle that letters should be held sacred confidences, just as all honorable people hold private conversations, not to be published without leave. But in authorizing Mr. Atkinson to print her letters, if he pleased, she maintained that she was not departing from this principle; for it was only the same as it would be if two friends agreed to make their conversation known. I feel deeply grateful to Mr. Atkinson for allowing me the privilege of presenting some of her letters to the public in this volume, and of perusing very many more.
