"Let me give you a history," he said, "and then perhaps you will relent. Listen. A man once became involved in the study of anatomy. It led him to destruction. He commenced the study in order to learn a profession; he hoped to become a physician. Materia medica, pharmacy, chemistry, enticed him at first, but after a time presented no charms. He was a dull student in much that men usually consider essential to the practice of medicine. He was not fitted to be a physician. Gradually he became absorbed in two branches, physiology and anatomy. Within his mental self a latent something developed that neither himself nor his friends had suspected. This was an increasing desire for knowledge concerning the human body. The insatiable craving for anatomy grew upon him, and as it did so other sections of medicine were neglected. Gradually he lost sight of his professional object; he dropped chemistry, materia medica, pharmacy, and at last, morbidly lived only in the aforenamed two branches. "His first visit to the dissecting room was disagreeable. The odor of putrid flesh, the sight of the mutilated bodies repulsed him. When first his hand, warm in life, touched the clammy flesh of a corpse, he shuddered. Then when his fingers came in contact with the viscera of a cadaver, that of a little child, he cried out in horror. The demonstrator of anatomy urged him on; he finally was induced to dissect part of the infant. The reflex action on his sensitive mind first stunned, and then warped his senses. His companions had to lead him from the room. 'Wash it off, wash it off,' he repeated, trying to throw his hand from his person. 'Horrid, horrible, unclean. The child is yet before me,' he insisted. Then he went into a fever and raved. 'Some mother will meet me on the street and curse me,' he cried. 'That hand is red with the blood of my darling; it has desecrated the innocent dead, and mutilated that which is most precious to a mother. Take the hand away, wash it,' he shouted. 'The mother curses me; she demands retribution. Better that a man be dead than cursed by a mother whose child has been desecrated.' So the unfortunate being raved, dreaming all manner of horrid imaginings. But at last he recovered, a different man. He returned voluntarily to the dissecting-room, and wrapped himself in the uncouth work. Nothing in connection with corpse-mutilation was now offensive or unclean. He threw aside his other studies, he became a slave possessed of one idea. He scarcely took time to dine respectably; indeed, he often ate his lunch in the dissecting-room. The blood of a child was again and again on his fingers; it mattered not, he did not take the trouble to wash it off. 'The liver of man is not more sacred than the liver of a hog,' he argued; 'the flesh of a man is the same as other forms of animal food. When a person dies the vital heat escapes, consciousness is dissipated, and the cold, rigid remains are only animal.
