All these antique naturalists stood in advance of their centuries, yet were imbued with some of their credulity, and therefore were believed, and perhaps imagined themselves, to have acquired from the investigation of nature a power above nature, and from physics a sway over the spiritual world. Hardly less curious and imaginative were the early volumes of the Transactions of the Royal Society, in which the members, knowing little of the limits of natural possibility, were continually recording wonders, or proposing methods whereby wonders might be wrought.

But, to Georgiana, the most engrossing volume was a large folio from her husband's own hand, in which he had recorded every experiment of his scientific career, with its original aim, the methods adopted for its development, and its final success or failure, with the circumstances to which either event was attributable. The book, in truth, was both the history and emblem of his ardent, ambitious, imaginative, yet practical and laborious, life. He handled physical details, as if there were nothing beyond them; yet spiritualized them all, and redeemed himself from materialism, by his strong and eager aspiration towards the infinite. In his grasp, the veriest clod of earth assumed a soul. Georgiana, as she read, reverenced Aylmer, and loved him more profoundly than ever, but with a less entire dependence on his judgment than heretofore. Much as he had accomplished, she could not but observe that his most splendid successes were almost invariably failures, if compared with the ideal at which he aimed. His brightest diamonds were the merest pebbles, and felt to be so by himself, in comparison with the inestimable gems which lay hidden beyond his reach. The volume, rich with achievements that had won renown for its author, was yet as melancholy a record as ever mortal hand had penned. It was the sad confession, and continual exemplification, of the short-comings of the composite man – the spirit burthened with clay and working in matter – and of the despair that assails the higher nature, at finding itself so miserably thwarted by the earthly part. Perhaps every man of genius, in whatever sphere, might recognize the image of his own experience in Aylmer's journal.

So deeply did these reflections affect Georgiana, that she laid her face upon the open volume, and burst into tears. In this situation she was found by her husband.

»It is dangerous to read in a sorcerer's books,« said he, with a smile, though his countenance was uneasy and displeased. »Georgiana, there are pages in that volume, which I can scarcely glance over and keep my senses. Take heed lest it prove as detrimental to you!«

»It has made me worship you more than ever,« said she.

»Ah! wait for this one success,« rejoined he, »then worship me if you will. I shall deem myself hardly unworthy of it. But, come! I have sought you for the luxury of your voice. Sing to me, dearest!«

So she poured out the liquid music of her voice to quench the thirst of his spirit. He then took his leave, with a boyish exuberance of gaiety, assuring her that her seclusion would endure but a little longer, and that the result was already certain. Scarcely had he departed, when Georgiana felt irresistibly impelled to follow him. She had forgotten to inform Aylmer of a symptom, which, for two or three hours past, had begun to excite her attention. It was a sensation in the fatal birth-mark, not painful, but which induced a restlessness throughout her system. Hastening after her husband, she intruded, for the first time, into the laboratory.

The first thing that struck her eye was the furnace, that hot and feverish worker, with the intense glow of its fire, which, by the quantities of soot clustered above it, seemed to have been burning for ages. There was a distilling apparatus in full operation. Around the room were retorts, tubes, cylinders, crucibles, and other apparatus of chemical research. An electrical machine stood ready for immediate use. The atmosphere felt oppressively close, and was tainted with gaseous odors, which had been tormented forth by the processes of science. The severe and homely simplicity of the apartment, with its naked walls and brick pavement, looked strange, accustomed as Georgiana had become to the fantastic elegance of her boudoir. But what chiefly, indeed almost solely, drew her attention, was the aspect of Aylmer himself.

He was pale as death, anxious, and absorbed, and hung over the furnace as if it depended upon his utmost watchfulness whether the liquid, which it was distilling, should be the draught of immortal happiness or misery. How different from the sanguine and joyous mien that he had assumed for Georgiana's encouragement!

»Carefully now, Aminadab! Carefully, thou human machine! Carefully, thou man of clay!« muttered Aylmer, more to himself than his assistant. »Now, if there be a thought too much or too little, it is all over!«

»Hoh! hoh!« mumbled Aminadab – »look, master, look!«

Aylmer raised his eyes hastily, and at first reddened, then grew paler than ever, on beholding Georgiana.
