On Tuesday afternoon his way led him past the famous Rotterdam cake-shop. Before the door of the building, made of boards lightly joined together and decked with mirrors and gay pictures, a stout, pretty woman, in the bloom of youth, sat in a high arm-chair, pouring rapidly, with remarkable skill, liquid dough into the hot iron plate, provided with numerous indentations, that stood just on a level with her comfortably outspread lap. Her assistant hastily turned with a fork the little cakes, browning rapidly in the hollows of the iron, and when baked, laid them neatly on small plates. The waiter prepared them for purchasers by putting a large piece of yellow butter on the smoking pile. A tempting odor, that only too vividly recalled former enjoyment, rose from the fireplace, and Adrian's fingers were already examining the contents of his purse, when the negro's trumpet sounded and the quack doctor's cart stopped directly in front of the booth. The famous Doctor Morpurgo was a fine-looking man, dressed in bright scarlet, who had a thin, coalblack beard hanging over his breast. His movements were measured and haughty, the bows and gestures with which he saluted the assembled crowd, patronizing and affable. After a sufficient number of curious persons had gathered around his cart, which was stocked with boxes and vials, he began to address them in broken Dutch, spiced with numerous foreign words. He praised the goodness of the Providence which had created the marvel of human organism. Everything, he said, was arranged and formed wisely and in the best possible manner, but in one respect nature fared badly in the presence of adepts. "Do you know where the error is, ladies and gentlemen?" he asked. "In the purse," cried a merry barber's clerk, "it grows prematurely thin every day." "Right, my son," answered the quack graciously. "But nature also provides it with the great door from which your answer has come. Your teeth are a bungling piece of workmanship. They appear with pain, decay with time, and so long as they last torture those who do not industriously attend to them. But art will correct nature. See this box--" and he now began to praise the tooth-powder and cure for toothache he had invented. Next he passed to the head, and described in vivid colors, its various pains. But they too were to be cured, people need only buy his arcanum. It was to be had for a trifle, and whoever bought it could sweep away every headache, even the worst, as with a broom. Adrian listened to the famous doctor with mouth wide open. Specially sweet odors floated over to him from the hot surface of the stove before the booth, and he would have gladly allowed himself a plate of fresh cakes. The baker's stout wife even beckoned to him with a spoon, but he closed his hand around the purse and again turned his eyes towards the quack, whose cart was now surrounded by men and women buying tinctures and medicines.
