qualifications and instincts as a thorough gentleman to give lustre to the city of his residence and to the generation to which he belonged; a successful lawyer that stood in the front ranks of his profession; a cautious, far-seeing and wise legislator, distinguishing himself in the halls of legislation, national as well as state; a successful public speaker and a writer of great power and wide-spread popularity, he has left to the generations that succeed him the legacy of a noble example and a noble name.” Mr. Arnold was enrolled at the bar of the Supreme Court in Illinois Dec. 9, 1841, and in that same year he became counsel in a case which established his ability as a lawyer and brought him prominently before the profession. It was a time of great business depression, and a recreant legislature had passed an act of repudiation of public debts and providing that unless the property of a judgment debtor should bring two-thirds of its appraised value, it should not be sold under execution. Mr. Arnold was a determined opponent, of such legislation, and being employed by a New York judgment creditor to enforce his claim against a debtor, he attacked the constitutionality of the act, carried the case to the Supreme Court of the United States, where the case came on in January, 1843. Mr. Arnold presented an irrefutable written argument and Chief Justice Taney in one of the ablest and most elaborate opinions ever delivered in the court, sustained the position of the counsel for the appellant. Mr. Arnold was a powerful advocate whether before court or jury. He was exceedingly pains-taking in the preparation of his cases—which is half the battle with the lawyer—and before a jury he had no superior. As one of his associates at the bar has put it: “He was a learned lawyer, a jurist in the same sense of the term, and for more than thirty years stood at the head of the Chicago bar.”
