Life and Letters of Robert Browning [EPUB ebook] 

Preface
Such letters of Mr. Browning's as appear, whole or in part, in the present volume have been in most cases given to me by the persons to whom they were addressed, or copied by Miss Browning from the originals under her care; but I owe to the daughter of the Rev. W. J. Fox—Mrs. Bridell Fox—those written to her father and to Miss Flower; the two interesting extracts from her father's correspondence with herself and Mr. Browning's note to Mr. Robertson.
For my general material I have been largely indebted to Miss Browning. Her memory was the only existing record of her brother's boyhood and youth. It has been to me an unfailing as well as always accessible authority for that subsequent period of his life which I could only know in disconnected facts or his own fragmentary reminiscences. It is less true, indeed, to say that she has greatly helped me in writing this short biography than that without her help it could never have been undertaken.
I thank my friends Mrs. R. Courtenay Bell and Miss Hickey for their invaluable assistance in preparing the book for, and carrying it through the press; and I acknowledge with real gratitude the advantages derived by it from Mr. Dykes Campbell's large literary experience in his very careful final revision of the proofs.
