MRS. MONTAGU, of Upper Berkley Street, Portman Square. A lady of considerable literary accomplishments, and whose charity, in bestowing an annual May-day Dinner upon the Chimney Sweepers, is well known. Her maiden name was Robinson, and she was nearly related to the late Primate of Ireland. She has written An Essay on the Writings and Genius of Shakspeare, compared with the Greek and French dramatic Poets, with some Remarks upon the Misrepresentation of M. de Voltaire, in octavo, the first edition of which was published in 1769, and a second in 1776. This performance has obtained her much applause.
