He next studied physics and ethics--the former under the celebrated Beccaria, but not a single definition remained in his head. These studies, however, as well as those in civil and canon law, which he had commenced, were interrupted by a violent illness, which rendered it necessary for him to have his head shaved, and to wear a wig. His companions, at first, tormented him greatly about this wig, and used to tear it from his head; but he soon succeeded in appeasing the public indignation, by being always the first to throw the unhappy ornament in question up in the air, calling it by every opprobrious epithet. From that time he remained the least persecuted wig-wearer among the two or three who were in this predicament. He now took lessons on the piano, and in geography, fencing, and dancing. He imbibed the most invincible dislike to the latter, which he attributed to the grimaces and extraordinary contortions of the master, a Frenchman just arrived from Paris. He dates from this period that extreme hatred of the French nation which remained with him through life, and which was one of the strangest features in his character. His uncle died this year (1763), and as he was now fourteen, the age at which, by the laws of Piedmont, minors are freed from the care of their guardians, and are placed under curators, who leave them masters of their income, and can only prevent the alienation of their real estates, he found himself possessed of considerable property, which was still farther increased by his uncle's fortune. Having obtained the degree of master of arts, by passing a public examination in logic, physics, and geometry, he was rewarded by being allowed to attend the riding-school, a thing he had always ardently desired. He became an expert horseman, and attributes to this exercise the recovery of his health, which now rapidly improved. "Having buried my uncle, changed my guardian into a curator, obtained my master's degree, got rid of my attendant Andrea, and mounted a steed, it is incredible how proud I became. I told the authorities plainly that I was sick of studying law, and that I would not go on with it. After a consultation, they determined to remove me into the first apartment, which I entered on the 8th May, 1763."
