Dr. Stevenson stated in his evidence, he first made an analysis of a portion of the body of Mrs. Holmes on January 19, and extracted 1·31 grain of strychnine, but no other poison. Subsequently he examined the two packets discovered under the bed, and found one contained 33¾ grains of powdered strychnine, and the other, which presented the appearance of having had the powder shaken out, a few minute crystals of strychnine. In each case it was the pure alkaloid. The body was exhumed nineteen days after death, and he then made an analysis of all the chief organs, and obtained therefrom a total quantity of 3·69 grains of strychnine. Death usually occurred about half an hour after the commencement of the symptoms. He judged there could not have been less than ten grains of strychnine in the body at the time of death. The jury found Walter Horsford guilty, and he was sentenced to death. CHAPTER XXIII THE GREAT AMERICAN POISON MYSTERY ONE of the most carefully planned murders by means of poison in modern times was investigated at the trial of Roland B. Molineux, who was charged with causing the death of Mrs. Catherine J. Adams in New York in 1899. On November 10, 1898, a Mr. Henry C. Barnett, a produce booker, who was a member of the Knickerbocker Athletic Club, one of the most prominent social organizations in New York, received by post at the club a sample box of Kutnow's Powder. He was in the habit of taking this and similar preparations for simple ailments, and soon after receiving the box he took a dose of its contents. He became ill immediately afterwards, and was thought to be suffering from diphtheria. That he had a slight attack of this disease there is little doubt, as the fact was proved from a bacteriological examination made by his medical attendant. He left his bed earlier than the doctor advised, and died presumably of heart failure. The contents of the box, however, were examined, which led to the discovery that the powder had been tampered with and mixed with cyanide of mercury; and although Mr. Barnett had died from natural causes, it seemed clear an attempt had been made to poison him by some one who knew he was in the habit of taking this powder. The investigation, however, does not appear to have been carried farther. The next chapter in the story occurred in connection with a Mr. Harry Cornish, who occupied the position of physical director to the Knickerbocker Athletic Club. A day or two before Christmas in the same year, a packet directed to him was delivered by post at his address. It contained a box, in which, on opening, he found at one end a silver article for holding matches or toothpicks; at the other end was a bottle labelled "Emerson's Bromo-seltzer," and between the two was packed some soft tissue paper.
