"'Blind Tom,' the wonderful negro-boy pianist, made his _debut_ in Glasgow yesterday, when he gave three of his entertainments, or rather musical exhibitions, in the Merchants' Hall,--two during the day, and one in the evening. He is, without doubt, an extraordinary lad; born blind, though he is now able to distinguish light from darkness; and having a defect in some of his mental faculties, though what that defect is it is very difficult to say. Nature seems to have made up for these deficiencies by endowing him with a marvellously acute ear and a retentive memory. It is not uncommon to find blind people with their other senses much more highly developed, and much more susceptible of impression, than in people possessing all their faculties; but in no case have we ever heard or known of one with auditory nerves so fine, or with memory so powerful, as 'Blind Tom.' Mozart, when a mere child, was noted for the delicacy of his ear, and for his ability to produce music on a first hearing; but Burney, in his 'History of Music,' records no instance at all coming up to this negro boy for his attainments in phonetics, and his power of retention and reproduction of sound.... He plays first a number of difficult passages from the best composers; and then any one is invited to come forward and perform any piece he likes, the more difficult the more acceptable, and, if original, still more preferable. Tom immediately sits down at the piano, and produces _verbatim et literatim_ the whole of what he has just heard. To show that it is not at all necessary that he should be acquainted with any piece beforehand to reproduce it, he invites any one to strike a number of notes simultaneously with the hand, or with both hands; and immediately, as we heard him do yesterday, he repeats at length, and without the slightest hesitation, the whole of the letters, with all their inflections, representing the notes. Nor are his wondrous powers confined to the piano, on which he can produce imitations of various instruments, and play two different tunes--one in common time, and a second in triple--while he sings a third; but he can with the voice produce, with the utmost accuracy, any note which his audience may suggest. Yesterday afternoon, for instance, he was asked to sing B flat, F sharp, and the upper A,--a very difficult combination; and, beginning with the latter, he at once satisfied his auditors of his success. One very funny feat he executed, which, as much as any thing else, showed what he could do. When at Aberdeen, as Dr. Howard explained, Tom heard, in a large ante-room adjoining the hall where he was, a teacher of dancing tuning his fiddle, the strings of which apparently had been rather difficult to get tightened
