Everywhere in artistic and aristocratic circles at the French capital Viotti's presence was eagerly sought. Private concerts were so much the vogue in Paris that musicians of high rank found more profit in these than in such as were given to the miscellaneous public. A delightful artistic rendezvous was the hotel of the Comte de Balck, an enthusiastic patron and friend of musicians. Here Viotti's friend, Garat, whose voice had so great a range as to cover both the tenor and barytone registers, was wont to sing; and here young Orfila, the brilliant chemist, displayed his magnificent tenor voice in such a manner as to attract the most tempting offers from managers that he should desert the laboratory for the stage. But the young Portuguese was fascinated with science, and was already far advanced in the career which made him in his day the greatest of all authorities on toxicological chemistry. The most brilliant and gifted men and women of Paris haunted these reunions, and Viotti always appeared at his best amid such surroundings. Another favorite resort of his was the house of Mme. Montegerault at Montmorency, a lady who was a brilliant pianist. Sometimes she would seat herself at her instrument and begin an improvisation, and Viotti, seizing his violin, would join in the performance, and in a series of extemporaneous passages display his great powers to the delight of all present. He evinced the greatest distaste for solo playing at public concerts, and, aside from charity performances, only consented once to such an exhibition of his talents. A singular concert was arranged to take place on the fifth story of a house in Paris, the apartment being occupied by a friend of Viotti, who was also a member of the Government. "I will play," he said, on being urged, "but only on one condition, and that is, that the audience shall come up here to us--we have long enough descended to them; but times are changed, and now we may compel them to rise to our level"; or something to that effect. It took place in due course, and was a very brilliant concert indeed. The only ornament was a bust of Jean Jacques Rousseau. A large number of distinguished artists, both instrumental and vocal, were present, and a most aristocratic audience. A good deal of Boccherini's music was performed that evening, and though many of the titled personages had mounted to the fifth floor for the first time in their lives, so complete was the success of the concert that not one descended without regret, and all were warm in their praise of the performances of the distinguished violinist.
