"The needle was now withdrawn from the left lobe, and passed in the same way into the (brain) substance of the right. ... When the needle entered the brain substance, SHE COMPLAINED OF ACUTE PAIN IN THE NECK. IN ORDER TO DEVELOP MORE DECIDED REACTIONS, the strength of the current was increased by drawing out the wooden cylinder one inch. When communication was made with the needles, HER COUNTENANCE EXHIBITED GREAT DISTRESS, and she began to cry. Very soon, the left hand was extended as if in the act of taking hold of some object in front of her; the arm presently was agitated with clonic spasms; her eyes became fixed with pupils widely dilated; lips were blue, and SHE FROTHED AT THE MOUTH; HER BREATHING BECAME STERTOROUS; SHE LOST CONSCIOUSNESS AND WAS VIOLENTLY CONVULSED. The convulsion lasted five minutes, and was succeeded by coma. She returned to consciousness in twenty minutes from the beginning of the attack." The experiment was a success. Upon the body of the poor servant girl, the distinguished vivisector had produced the "violent epileptiform convulsion" which Fritsch and Hitzig and Ferrier had induced in animals, by the same method of experimentation. There are those who feel that further vivisecting should have then ceased, and that Mary Rafferty should have been allowed to die in peace. Such views, however, were not permitted by the experimenter to interfere with his zeal for scientific research. Other "observations" were made, and the needles were again passed into the brain, evoking almost the same phenomena. The final experiments were thus described by the vivisector:[1] "Two days subsequent to observation No. 4, Mary was brought into the electrical room with the intention to subject the posterior lobes (of the brain) to galvanic excitation. The proposed experiment was abandoned. SHE WAS PALE AND DEPRESSED; HER LIPS WERE BLUE, AND SHE HAD EVIDENT DIFFICULTY IN LOCOMOTION. She complained greatly of numbness.... On further examination, there was found to be decided PARESIS and rigidity of the muscles of the right side.... She became very pale; her eyes closed; and she was about to pass into unconsciousness, when we placed her in the recumbent posture, and Dr. S. gave her, at my request, chloroform by inhalation. "The day after observation No. 5, MARY WAS DECIDEDLY WORSE. She remained in bed, was stupid and incoherent. In the evening she had a convulsive seizure.... AFTER THIS, SHE LAPSED INTO PROFOUND UNCONSCIOUSNESS, AND WAS FOUND TO BE COMPLETELY PARALYZED ON THE RIGHT SIDE.... The pupils were dilated and motionless." [1] Italics not in original. When did death come to her release? We do not know; the omission is significant; it may have been within a few moments. The next sentence in the report is headed by the ominous word, "AUTOPSY." The brain was taken out, and the track of the needles traced therein. One needle had penetrated an inch and a half. There was evidence of "INTENSE VASCULAR CONGESTION."
