Bookplate of Oxford University English Faculty Library; Given to the Library by Miss M.M. Lascelles
I believe this edition of 1791 to be set up from the 'new' (i.e., third) edition of 1785.
I have found no difference except the omission of the notice announcing the collected works, to be published under the supervision of Sir John Hawkins. Even the apology to the Macleods fo Raasay has been retained. M.M.L.
