Paganini's favourite violin was a Joseph Guarnerius. An Italian amateur, who evidently knew its value, lent it to the great maestro, and, after hearing him play upon it, declared that no other hand should touch it, and presented it to Paganini. He left it to his native city of Genoa, where it is preserved in the town hall. Ferdinand Barth, who painted "Paganini in Prison," was the son of a carpenter, and was born in Bavaria in the early forties. For some time he worked as a wood carver, and then began to paint, and studied at the Munich Academy, under Piloty. Probably his best known picture is "Choosing the Casket," in which he has depicted the familiar scene from the "Merchant of Venice." MENDELSSOHN. Like Mozart, the composer of the "Songs without Words" had a sister, a few years older than himself, who was possessed of great musical talent. Mendelssohn's sister, Fanny, was born in 1805. In 1829 she became the wife of Wilhelm Hensel, a noted historical and portrait painter. Probably the most valuable and interesting of his works is the series of portraits of all the celebrities who, from time to time, were the guests of the Mendelssohn family. They number more than a thousand drawings, and include, besides likenesses of poets, painters, and philosophers, portraits of many people famous in the annals of music,--Weber, Paganini, Ernst, Hiller, Liszt, Clara Schumann, Gounod, Clara Novello, Lablache, and Grisi. Rockstro tells the story of Fanny Mendelssohn's early death in the following words: "On Friday afternoon, the 14th of May, 1847, Madame Hensel, the beloved sister Fanny, to whom, from earliest infancy, Felix, the child, the boy, the man, had committed every secret of his beautiful art life; the kindred spirit, with whom he had shared his every dream before his first attempt to translate it into sound; the faithful friend who had been more to him than any other member of the happy circle in the Leipziger Strasse, of which, from first to last, she was the very life and soul,--Fanny Hensel, the sister, the artist, the poet, while conducting a rehearsal of the music for the next bright Sunday gathering, was suddenly seized with paralysis; suffered her hands to fall powerless from the piano at which she had so often presided; and, an hour before midnight, was called away to join the beloved parents whose death had been as sudden and painless as her own. She had hoped and prayed that she, too, might pass away as they had done, and her prayer was granted; to her exceeding gain, but to the endless grief of the brother who had loved her as himself. On Sunday morning, in place of the piano, a coffin, covered with flowers, stood in the well-known hall in the Garden House. And the life, of which that Garden House had so long been the cherished home, became henceforth a memory of the past."
