Joseph Cooper Walker, Esq. of St. Valery, near Bray, Ireland, died upon the 12th of April 1810. He published two works upon Irish Antiquities, and an Historical Memoir on Italian Tragedy, as well as an Historical and Critical Essay on the Revival of the Drama in Italy. His posthumous work, the Memoirs of Tassoni, was edited by his brother, who in his preface, has inserted much interesting matter respecting the author. Several of Mr. Walker's letters have been honored with a place in the printed correspondence of the celebrated Cesarotti; and among his correspondents, as enumerated by his brother, are the names of the greater part of the individuals then most distinguished by their love of antiquities and the belles-lettres in Britain.
