In order to soothe Georgiana, and, as it were, to release her mind from the burden of actual things, Aylmer now put in practice some of the light and playful secrets which science had taught him among its profounder lore.  Airy figures, absolutely bodiless ideas, and forms of unsubstantial beauty came and danced before her, imprinting their momentary footsteps on beams of light.  Though she had some indistinct idea of the method of these optical phenomena, still the illusion was almost perfect enough to warrant the belief that her husband possessed sway over the spiritual world.  Then again, when she felt a wish to look forth from her seclusion, immediately, as if her thoughts were answered, the procession of external existence flitted across a screen.  The scenery and the figures of actual life were perfectly represented, but with that bewitching yet indescribable difference which always makes a picture, an image, or a shadow so much more attractive than the original.  When wearied of this, Aylmer bade her cast her eyes upon a vessel containing a quantity of earth.  She did so, with little interest at first; but was soon startled to perceive the germ of a plant shooting upward from the soil.  Then came the slender stalk; the leaves gradually unfolded themselves; and amid them was a perfect and lovely flower.

“It is magical!” cried Georgiana.  “I dare not touch it.”

“Nay, pluck it.” answered Aylmer,—­“pluck it, and inhale its brief perfume while you may.  The flower will wither in a few moments and leave nothing save its brown seed-vessels; but thence may be perpetuated a race as ephemeral as itself.”

But Georgiana had no sooner touched the flower than the whole plant suffered a blight, its leaves turning coal-black as if by the agency of fire.

“There was too powerful a stimulus,” said Aylmer, thoughtfully.

To make up for this abortive experiment, he proposed to take her portrait by a scientific process of his own invention.  It was to be effected by rays of light striking upon a polished plate of metal.  Georgiana assented; but, on looking at the result, was affrighted to find the features of the portrait blurred and indefinable; while the minute figure of a hand appeared where the cheek should have been.  Aylmer snatched the metallic plate and threw it into a jar of corrosive acid.

Soon, however, he forgot these mortifying failures.  In the intervals of study and chemical experiment he came to her flushed and exhausted, but seemed invigorated by her presence, and spoke in glowing language of the resources of his art.  He gave a history of the long dynasty of the alchemists, who spent so many ages in quest of the universal solvent by which the golden principle might be elicited from all things vile and base.  Aylmer appeared to believe that, by the plainest scientific logic, it was altogether within the limits of possibility to discover this long-sought medium.  “But,” he added,
