"Oho! he!" murmured the gentlemen in a contemptuous tone, and old Heim bestowed upon him a hearty "Scoundrel!"

"Well," Johannes continued, "I am sure you will not imagine me such a fool as to have fallen in love at the first sight of a beautiful face, but the apparition that I have just described presented a combination of what is most attractive to a man,--'beauty, intellect, and virtue.'"

"Virtue!" Herbert repeated; "are you so sure of that?"

"Yes. If Fräulein Hartwich were not virtuous, she would not live in such strict retirement. Those who have tasted the cup of self-indulgence are too apt to return to it; the truly pure alone can find contentment in seclusion and loneliness, inspired only by a grand idea! I go still further, and, as a physiologist, upon the ground of the preservation of force, maintain that a woman engaged in such unusual and profound studies needs all her vital energy for her work, and is dead to all the pleasures of sense. Hence we so often find entire lack of sensibility in women accustomed to great mental activity,--because their supply of vital force is not sufficient for the double occupation of thinking and feeling. And therefore my only fear is that there is no warm heart throbbing within that exquisite form."

The professors looked significantly at one another, and the Staatsräthin exchanged anxious whispers with Angelika.

"Well," said Herbert, as he arose from his chair, "I propose that we leave our respected associate to his dreams, and wish for his sake that his pupil may not be as accomplished upon the subject of the nerves of sensation as upon the inhibitory nerves."

The gentlemen all arose.

Johannes looked fixedly at Herbert and said, "I am no dreamer, Doctor Herbert, although I believe in the virtue that requires no certificate of character. And, I repeat, I believe so firmly in this virtue, that I denounce as a slanderer the man who dares to assail it by a single word!"

"Sir!" cried Herbert with irritation, "your remark is insulting!"

"Only to him to whom it may apply!" said Johannes calmly.
