"You need sleep first, and then a tonic," said the apothecary in a business-like tone.

"I slept until late this morning. It did me no good. I am half dead myself. Yes, if I could sleep again it might do me good."

"Go home and go to bed. If I were in your place I would not drink any more of that liquor. It will only make you worse."

"Give me something to make me sleep. I will take it."

The apothecary looked long at him and seemed to be weighing something in his judgment. An evil thought crossed his mind. He was very poor. He knew well enough, in spite of Meschini's protestations, that he was not so poor as he pretended to be. If he were he could not have paid so regularly for the chemicals and for the experiments necessary to the preparation of his inks. More than once the operations had proved to be expensive, but the librarian had never complained, though he haggled for a baiocco over his dinner at Cicco's wine shop, and was generally angry when he lost a paul at cards. He had money somewhere. It was evident that he was in a highly nervous state. If he could be induced to take opium once or twice it might become a habit. To sell opium was very profitable, and Colaisso knew well enough the power of the vice and the proportions it would soon assume, especially if Meschini thought the medicine contained only some harmless drug.

"Very well," said the apothecary. "I will make you a draught. But you must be sure that you are ready to sleep when you take it. It acts very quickly."

The draught which Meschini carried home with him was nothing but weak laudanum and water. It looked innocent enough, in the little glass bottle labelled "Sleeping potion." But the effect of it, as Colaisso had told him, was very rapid. Exhausted by all he had suffered, the librarian closed the windows of his room and lay down to rest. In a quarter of an hour he was in a heavy sleep. In his dreams he was happier than he had ever been before. The whole world seemed to be his, to use as he pleased. He was transformed into a magnificent being such as he had never imagined in his waking hours. He passed from one scene of splendour to another, from glory to glory, surrounded by forms of beauty, by showers of golden light in a beatitude beyond all description. It was as though he had suddenly become emperor of the whole universe. He floated through wondrous regions of soft colour, and strains of divine music sounded in his ears. Gentle hands carried him with an easy swaying motion to transcendent heights, where every breath he drew was like a draught of sparkling life. His whole being was filled with something which he knew was happiness, until he felt as though he could not contain the overflowing joy. At one moment he glided beyond the clouds through a gorgeous sunset; at another he was lying on a soft invisible couch, looking out to the bright distance—distance that never ended, never could end, but the contemplation of which was rapture, the greater for being inexplicable. An exquisite new sense was in him, corresponding to no bodily instinct, but rejoicing wildly in something that could not be defined, nor understood, nor measured, but only felt.

At last he began to descend, slowly at first and then with increasing speed, till he grew giddy and unconscious in the fall. He awoke and uttered a cry of terror. It was night, and he was alone in the dark. He was chilled to the bone, too, and his head was heavy, but the darkness was unbearable, and though he would gladly have slept again he dared not remain an instant without a light. He groped about for his matches, found them, and lit a candle. A neighbouring clock tolled out the hour of midnight, and the sound of the bells terrified him beyond measure. Cold, miserable, in an agony of fear, his nervousness doubled by the opium and by a need of food of which he was not aware, there was but one remedy within his reach. The sleeping potion had been calculated for one occasion only, and it was all gone. He tried to drain a few drops from the phial, and a drowsy, half-sickening odour rose from it to his nostrils. But there was nothing left, nothing but the brandy, and little more than half a bottle of that. It was enough for his present need, however, and more than enough. He drank greedily, for he was parched with thirst, though hardly conscious of the fact. Then he slept till morning. But when he opened his eyes he was conscious that he was in a worse state than on the previous day. He was not only nervous but exhausted, and it was with feeble steps that he made his way to his friend's shop, in order to procure a double dose of the sleeping mixture. If he could sleep through the twenty-four hours, he thought, so as not to wake up in the dead of night, he should be better. When he made his appearance Tiberio Colaisso knew what he wanted, and although he had half repented of what he had done, the renewed possibility of selling the precious drug was a temptation he could not withstand.

One day succeeded another, and each morning saw Arnoldo Meschini crossing the Ponte Quattro Capi on his way to the apothecary's. In the ordinary course of human nature a man does not become an opium-eater in a day, nor even, perhaps, in a week, but to the librarian the narcotic became a necessity almost from the first. Its action, combined with incessant doses of alcohol, was destructive, but the man's constitution was stronger than would have been believed. He possessed, moreover, a great power of controlling his features when he was not assailed by supernatural fears, and so it came about that, living almost in solitude, no one in the Palazzo Montevarchi was aware of his state. It was bad enough, indeed, for when he was not under the influence of brandy he was sleeping from the effects of opium. In three days he was willing to pay anything the apothecary asked, and seemed scarcely conscious of the payments he made. He kept up a show of playing the accustomed game of cards, but he was absent-minded, and was not even angry at his daily losses. The apothecary had more money in his pocket than he had possessed for many a day. As Arnoldo Meschini sank deeper and deeper, the chemist's spirits rose, and he began to assume an air of unwonted prosperity. One of the earliest results of the librarian's degraded condition was that Tiberio Colaisso procured himself a new green smoking cap ornamented profusely with fresh silver lace.
