The Art of Cross-Examination / With the Cross-Examinations of Important Witnesses in Some Celebrated Cases

by Francis L. Wellman

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.

Harris had made the acquaintance of Miss Potts in the summer of 1889, and all during the winter paid marked attention to her. The following spring, while visiting her uncle, who was a doctor, she was delivered of a four months' child, and was obliged to confess to her mother that she was secretly married to Harris under assumed names, and that her student husband had himself performed an abortion upon her.

Harris was sent for. He acknowledged the truth of his wife's statements, but refused to make the marriage public. From this time on, till the day of her daughter's death, the wretched mother made every effort to induce Harris to acknowledge his wife publicly. She finally wrote him on the 20th of January, 1891, "You must go on the 8th of February, the anniversary of your secret marriage, before a minister of the gospel, and there have a Christian marriage performed—no other course than this will any longer be satisfactory to me or keep me quiet."

That very day Harris ordered at an apothecary store six capsules, each containing 4-1/2 grains of quinine and 1/6 of a grain of morphine, and had the box marked: "C. W. H. Student. One before retiring." Miss Potts had been complaining of sick headaches, and Harris gave her four of these capsules as an ostensible remedy. He then wrote to Mrs. Potts that he would agree to her terms "unless some other way could be found of satisfying her scruples," and went hurriedly to Old Point Comfort. Upon hearing from his wife that the capsules made her worse instead of better, he still persuaded her to continue taking them. On the day of her death she complained to her mother about the medicine Carlyle had given her, and threatened to throw the box with the remaining capsule out of the window. Her mother persuaded her to try this last one, which she promised to do. Miss Potts slept in a room with three classmates who, on this particular night, had gone to a symphony concert. Upon their return they found Helen asleep, but woke her up and learned from her that she had been having "such beautiful dreams," she "had been dreaming of Carl." Then she complained of feeling numb, and becoming frightened, begged the girls not to let her go to sleep. She repeated that she had taken the medicine Harris had given her, and asked them if they thought it possible that he would give her anything to harm her. She soon fell into a profound coma, breathing only twice to the minute. The doctors worked over her for eleven hours without restoring her to consciousness, when she stopped breathing entirely.

The autopsy, fifty-six days afterward, disclosed an apparently healthy body, and the chemical analysis of the contents of the stomach disclosed the presence of morphine but not of quinine, though the capsules as originally compounded by the druggist contained twenty-seven times as much quinine as morphine.

This astounding discovery led to the theory of the prosecution: that Harris had emptied the contents of one of the capsules, had substituted morphine in sufficient quantities to kill, in place of the 4-1/2 grains of quinine (to the eye, powdered quinine and morphine are identical), and had placed this fatal capsule in the box with the other three harmless ones, one to be taken each night. He had then fled from the city, not knowing which day would brand him a murderer.

Immediately after his wife's death Harris went to one of his medical friends and said: "I only gave her four capsules of the six I had made up; the two I kept out will show that they are perfectly harmless. No jury can convict me with those in my possession; they can be analyzed and proved to be harmless."

They were analyzed and it was proved that the prescription had been correctly compounded. But oftentimes the means a criminal uses in order to conceal his deed are the very means that Providence employs to reveal the sin that lies hidden in his soul. Harris failed to foresee that it was the preservation of these capsules that would really convict him. Miss Potts had taken all that he had given her, and no one could ever have been certain that it was not the druggist's awful mistake, had not these retained capsules been analyzed. When Harris emptied one capsule and reloaded it with morphine, he had himself become the druggist.

It was contended that Harris never intended to recognize Helen Potts as his wife. He married her in secret, it appeared at the trial,—as it were from his own lips through the medium of conversation with a friend,—"because he could not accomplish her ruin in any other way." He brought her to New York, was married to her before an alderman under assumed names, and then having accomplished his purpose, burned the evidence of their marriage, the false certificate. Finally, when the day was set upon which he must acknowledge her as his wife, he planned her death.
