But he knew too well the effects produced by a prolonged use of these injections to continue them beyond what was strictly indispensable; he therefore omitted them, and sleep left him. He tried them again; then, soon, as the small doses lost their efficacy, he gradually increased them. At the end of a certain time what he feared came to pass--his leanness increased; he lost his appetite, his muscular force, and his moral energy; his pale face began to wear the characteristic expression of the morphomaniac. Then he stopped, frightened. Should he continue, he would become a morphomaniac in a given time, and the apathy into which he fell prevented him from resisting the desire to absorb new doses of poison, a desire as imperious, as irresistible in morphinism as that of alcohol for the alcoholic, and more terrible in its effects--the perversion of the intellectual faculties, loss of will, of memory, of judgment, paralysis, or the mania that leads to suicide. If he did not continue, and these sleepless nights or the agitated sleep which maddened him should return, and following them, this over-excitement of the brain in troubling the nutrition of the encephalic mass, it might be the prelude of some grave cerebral affection. On one side the morphine habit; on the other, dementia from the constant excitement and disorganization of the brain. Between a fatally certain result and one that was possible he did not hesitate. He must give up morphine, and this choice forced itself upon him with so much more strength, because if morphine assured him sleep at night, it by no means gave him tranquil days--quite the contrary. He began to use this remedy at night when he fell under the influence of certain ideas; during the day when applying himself to work, by an effort of will he escaped from these ideas, and was the man he had always been, master of his strength and mind. But the action of the morphine rapidly weakened this all-powerful will, so much so, that when these ideas crossed his mind during his working hours he had not the energy to drive them away. He tried to shake them off, but in vain; they would not leave his brain, to which they clung and encompassed it with increasing strength. Truly, those two corpses troubled him horribly. Was it not exasperating for a man who had seen and dissected so many, that there should be always two before his eyes, even when they were closed--that of this old rascal and of this unfortunate woman? In order not to complicate this impression with another that humiliated him, he got rid of the packages of bank bills taken from Caffie, by sending them “as restitution” to the director of public charities. But this had no appreciable effect. The thought of Florentin troubled him also; and if he saw Caffie lying in his chair, Madame Dammauville motionless and pink on her bed, to him it was not less cruel to see Florentin between the decks of the vessel that would soon carry him to New Caledonia.
