Amongst the books to which I am indebted for my material in my endeavour to draw various phases of life and character in England at the beginning of the century, I would particularly mention Ashton's "Dawn of the Nineteenth Century;" Gronow's "Reminiscences;" Fitzgerald's "Life and Times of George IV.;" Jesse's "Life of Brummell;" "Boxiana;" "Pugilistica;" Harper's "Brighton Road;" Robinson's "Last Earl of Barrymore" and "Old Q.;" Rice's "History of the Turf;" Tristram's "Coaching Days;" James's "Naval History;" Clark Russell's "Collingwood" and "Nelson."

I am also much indebted to my friends Mr. J. C. Parkinson and Robert Barr for information upon the subject of the ring.
