As he led her over the threshold of the laboratory Georgiana was cold and tremulous. Aylmer looked cheerfully into her face, with intent to reassure her, but was so startled with the intense glow of the birthmark upon the whiteness of her cheek that he could not restrain a strong convulsive shudder. His wife fainted. "Aminadab! Aminadab!" shouted Aylmer, stamping violently on the floor. Forthwith there issued from an inner apartment a man of low stature, but bulky frame, with shaggy hair hanging about his visage, which was grimed with the vapors of the furnace. This personage had been Aylmer's underworker during his whole scientific career, and was admirably fitted for that office by his great mechanical readiness, and the skill with which, while incapable of comprehending a single principle, he executed all the details of his master's experiments. With his vast strength, his shaggy hair, his smoky aspect, and the indescribable earthiness that incrusted him, he seemed to represent man's physical nature; while Aylmer's slender figure, and pale, intellectual face, were no less apt a type of the spiritual element. "Throw open the door of the boudoir, Aminadab," said Aylmer, "and burn a pastil." "Yes, master," answered Aminadab, looking intently at the lifeless form of Georgiana; and then he muttered to himself, "If she were my wife, I'd never part with that birthmark." When Georgiana recovered consciousness she found herself breathing an atmosphere of penetrating fragrance, the gentle potency of which had recalled her from her death-like faintness. The scene around her looked like enchantment. Aylmer had converted those smoky, dingy, sombre rooms, where he had spent his brightest years in recondite pursuits, into a series of beautiful apartments not unfit to be the secluded abode of a lovely woman. The walls were hung with gorgeous curtains, which imparted the combination of grandeur and grace that no other species of adornment can achieve; and, as they fell from the ceiling to the floor, their rich and ponderous folds, concealing all angles and straight lines, appeared to shut in the scene from infinite space. For aught Georgiana knew, it might be a pavilion among the clouds. And Aylmer, excluding the sunshine, which would have interfered with his chemical processes, had supplied its place with perfumed lamps, emitting flames of various hue, but all uniting in a soft, impurpled radiance. He now knelt by his wife's side, watching her earnestly, but without alarm; for he was confident in his science, and felt that he could draw a magic circle round her within which no evil might intrude. "Where am I? Ah, I remember," said Georgiana, faintly; and she placed her hand over her cheek to hide the terrible mark from her husband's eyes. "Fear not, dearest!" exclaimed he. "Do not shrink from me! Believe me, Georgiana, I even rejoice in this single imperfection, since it will be such a rapture to remove it."
