"Southey, _Omniana_, i. 251. Coleridge asserts (_Literary Remains_, i. 303.), that there is now extent, in MS., a folio volume of unprinted sermons by Jeremy Taylor. It would be very interesting to learn in what region of the world so great a treasure has been suffered to rust during a hundred and fifty years."--Willmott's _Life of Bishop Jeremy Taylor_, p. 87. OXONIENSIS. _Papers of John Wilkes._ John Wilkes, it is well known, sent to the newspapers copies of Lord Weymouth's and Lord Barrington's Letters respecting the riots in St. George's Fields in 1768. We Can easily conjecture how he did or how he might have, got possession of a copy of Weymouth's Letter, which was addressed to the magistrates of Surrey; but Barrington's letter was strictly official, and directed to the "Field officers, in staff waiting, for the three regiments of Foot Guards." Has the circumstance ever been explained? If so, where? Can any of your readers inform me the _exact date_ of the first publication of Barrington's Letter in the newspaper? Is it not time that Wilkes' Letters and MSS. were deposited in some of our public libraries? They would throw light on many obscure points of history. They were left by Miss Wilkes to Mr. Elmsley, "to whose judgement and delicacy" she confided them. They were subsequently, I believe, in the legal possession of his son, the Principal of St. Alban's; but really of Mr. Hallam. W. _John Ross Mackay._ The following is from a work lately published, _Chronicles and Characters of the Stock Exchange_, by John Francis:-- "'The Peace of 1763,' said John Ross Mackay, Private Secretary to the Earl of Bute, and afterwards Treasurer to the Ordnance, 'was carried through and approved by pecuniary distribution.'" Will Mr. Francis, or any of your contributors, inform me where I can find the original statement? D. * * * * * NOTES ON BOOKS, CATALOGUES, SALES, ETC.
