“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.”

“Ho! ho!” mumbled Aminadab.  “Look, master! look!”

Aylmer raised his eyes hastily, and at first reddened, then grew paler than ever, on beholding Georgiana.  He rushed towards her and seized her arm with a gripe that left the print of his fingers upon it.

“Why do you come hither?  Have you no trust in your husband?” cried he, impetuously.  “Would you throw the blight of that fatal birthmark over my labors?  It is not well done.  Go, prying woman! go!”

“Nay, Aylmer,” said Georgiana with the firmness of which she possessed no stinted endowment, “it is not you that have a right to complain.  You mistrust your wife; you have concealed the anxiety with which you watch the development of this experiment.  Think not so unworthily of me, my husband.  Tell me all the risk we run, and fear not that I shall shrink; for my share in it is far less than your own.”

“No, no, Georgiana!” said Aylmer, impatiently; “it must not be.”

“I submit,” replied she, calmly.  “And, Aylmer, I shall quaff whatever draught you bring me; but it will be on the same principle that would induce me to take a dose of poison if offered by your hand.”

“My noble wife,” said Aylmer, deeply moved, “I knew not the height and depth of your nature until now.  Nothing shall be concealed.  Know, then, that this crimson hand, superficial as it seems, has clutched its grasp into your being with a strength of which I had no previous conception.  I have already administered agents powerful enough to do aught except to change your entire physical system.  Only one thing remains to be tried.  If that fail us we are ruined.”

“Why did you hesitate to tell me this?” asked she.

“Because, Georgiana,” said Aylmer, in a low voice, “there is danger.”

“Danger?  There is but one danger,—­that this horrible stigma shall be left upon my cheek!” cried Georgiana.  “Remove it, remove it, whatever be the cost, or we shall both go mad!”

“Heaven knows your words are too true,” said Aylmer, sadly.  “And now, dearest, return to your boudoir.  In a little while all will be tested.”

He conducted her back and took leave of her with a solemn tenderness which spoke far more than his words how much was now at stake.  After his departure Georgiana became rapt in musings.  She considered the character of Aylmer, and did it completer justice than at any previous moment.  Her heart exulted, while it trembled, at his honorable love,—­so pure and lofty that it would accept nothing less than perfection nor miserably make itself contented with an earthlier nature than he had dreamed of.  She felt how much more precious was such a sentiment than that meaner kind which would have borne with the imperfection
