Camillo Sivori has returned to London, after an absence of
several years, chiefly spent in America. He made his first appearance at the meeting of the Beethoven Quartet Society, on Thursday ; and delighted the audience as much as possible by his lovely tone, exquisite refinement, and graceful facility of execution. Sivori had been announced as the' leading attraction of Allcroft'a Promenade Concerts last week; a solo by him was inserted in the programme of the first concert ; and an apology made for his don-appearance. It turns out that he was never engaged by Mr. Allcroft at all, and knew nothing about him or his concerts. Such tricks ought to be exposed as often as they are found out; and Sivori, by exposing this one through the medium of the Times, has served. the public and the profession.
