_The Vellum-bound Junius_ (Vol. iii., pp. 262. 307.).--In the Number dated April 19, 1851, p. 307., is a request for information relative to the "Vellum-bound copy of Junius;" also a reference to the subject in a prior number of the "NOTES AND QUERIES." Not being in England, and not having the prior numbers, it is not possible to make myself acquainted with the subject contained in that reference, but I will endeavour to throw some light on the Query in the Number which has been forwarded to me. The writer of the _Letters of Junius_ was the secretary of the first Marquis of Lansdowne, better known as Lord Shelburne. From his Lordship he obtained all the political information necessary for his compositions. The late Marquis of Lansdowne possessed the copy bound in vellum (two volumes), with many notes on the margin in Lord Shelburne's handwriting; they were kept locked up in a beautiful ebony casket bound and ornamented with brass. That casket has disappeared, at least so I have been told, and not many years ago inquiry was made for it by the present head of that house. Maclean was a dark, strong-featured man, who wore his hat slouched over his eyes, and generally a large cloak. He often corrected the slips or proofs of his letters at Cox's, a well-known printer near Lincoln's Inn, who deemed himself bound in honour never to divulge what he knew of that publication, and was agitated when once suddenly spoken to on the subject near the door of the small room in which the proofs were corrected, and with a high and honourable feeling requested never to be again spoken to on the subject. The late President of the Royal Academy, Benjamin West, knew Maclean; and his son, the late Raphael West, told the writer of these remarks, that when a young man he had seen him in the evening at his father's in Newman Street, and once heard him repeat a passage in one of the letters which was not then published. A more correct and veracious man than Mr. R. West could not be. Maclean stammered, and was consequently of no use to Lord Shelburne as a debater and supporter in parliament. A place in the East Indies was obtained for him, and he sailed in the Aurora frigate for that dependency, and was lost in her at the same time with Falconer, the author of the poem entitled _The Shipwreck_. The able tract published by Mr. Pickering, Piccadilly, would constitute a fair foundation on which to build the inquiry. AEGROTUS. _Pursuits of Literature_ (Vol. iii., p. 240.).--I trust that the following notes may be useful in assisting your correspondent S. T. D. to ascertain "how the author of the _Pursuits of Literature_ became known." The first edition of the first part of the _Pursuits of Literature_ appears to have been published in quarto, by J. Owen, 168. Piccadilly, in 1794. In a volume of pamphlets I have the above bound up with the following:--
