Even to this day--ten years after the trial--there is a widespread belief among men, perhaps more especially among women, who did not attend the trial, but simply listened to the current gossip of the day and followed the newspaper accounts of the court proceedings, that Harris was innocent of the crime for the commission of which his life was forfeited to the state.
It is proposed in this chapter to discuss some of the facts that led up to the testimony of one of the most distinguished toxicologists in the country, who was called for the defence on the crucial point in the case; and to give extracts from his cross-examination, his failure to withstand which was the turning-point in the entire trial. He returned to his home in Philadelphia after he left the witness-stand, and openly declared in public, when asked to describe his experiences in New York, that he had "gone to New York only to make a fool of himself and return home again."
It is also proposed to give some of the _inside_ history of the case--facts that never came out at the trial, not because they were unknown at the time to the district attorney, nor unsusceptible of proof, but because the strict rules of evidence in such cases often, as it seems to the writer, withhold from the ears of the jury certain facts, the mere recital of which seems to conclude the question of guilt. For example, the rule forbidding the presentation to the jury of anything that was said by the victim of a homicide, even to witnesses surrounding the death-bed, unless the victim in express terms makes known his own belief that he cannot live, and that he has abandoned all _hope_ or expectation of recovery before he tells the tale of the manner in which he was slain, or the causes that led up to it, has allowed many a guilty prisoner, if not to escape entirely, at least to avoid the full penalty for the crime he had undoubtedly committed.
Carlyle Harris was a gentleman's son, with all the advantages of education and breeding. In his twenty-second year, and just after graduating with honors from the College of Physicians and Surgeons in New York City, he was indicted and tried for the murder of Miss Helen Potts, a young, pretty, intelligent, and talented school girl in attendance at Miss Day's Ladies' Boarding School, on 40th Street, New York City.
