Sivori now set out on extensive travels, and, after visiting England, proceeded, in 1846, to America, travelling through the United States, Mexico, and various parts of South America, spending eight years in these peregrinations, and amassing a considerable fortune. During this great tour he met with many adventures, frequently travelling on horseback, and at one time being at death's door with yellow fever. On his return to Europe he shared the fate of many musicians who have achieved financial success, and lost his money by unfortunate investment, which made it necessary for him to resume his travels. He therefore visited Great Britain, Switzerland, Germany, Spain, Portugal, etc. He was, of course, compared to many of the great violinists of his time, who all had their special merits. One criticism, in which Sivori is compared with Spohr, may be interesting: "Spohr is of colossal stature, and looks more like an ancient Roman than a Brunswicker; Sivori is the antithesis of Spohr in stature. Spohr has the severe phlegmatic Teutonic aspect; Sivori has the flashing Italian eye and variability of feature. Spohr stands firm and still; Sivori's body is all on the swing, he tears the notes, as it were, from his instrument. Spohr's refinement and polish have been the characteristics of his playing; in Sivori it is wild energy--the soul in arms--the determination to be up and doing--the daring impulse of youthful genius. Spohr's playing is remarkable for its repose and finish; Sivori electrifies by the most powerful appeals to the affections." Sivori was a man of generous impulses, and was seldom appealed to in vain to assist in a good cause. When his teacher, M. Dellepaine, was taken ill and was unable temporarily to fill his post of first violin at the theatre, and of director of the conservatoire at Genoa, Sivori replaced him in both and gave him the entire benefit of his services. After two years the teacher died, and Sivori still held the two places an entire year for the benefit of the widow, until a situation was procured for her which enabled her to live without further assistance. At one time Sivori felt that the instrument which he played was not so perfect as to satisfy him. He asked Paganini to sell him one, and the reply was, "I will not sell you the violin, but I will present it to you in compliment to your high talents." Sivori travelled to Nice to receive the instrument from his master's own hands. Paganini was then--it was in 1840--in a deplorable condition, and could hardly speak. He signified a desire to hear his pupil play once more, and Sivori, withdrawing to a room a little way off, so that the sound of the instrument would not be too loud, played whatever Paganini called for. About two weeks later Paganini died. In 1851 Halle wrote of him as follows: "Sivori was here lately, but caused little furore; such rubbish as the man plays now I had never heard, and really, as an artist, felt ashamed of him."
