All saw this, and no one dared to accept the challenge.

Felix had risen again, but only to fall into the arms of his nearest neighbor. He was stunned by the heavy blow; the blood was streaming from his nose and mouth.

A threatening murmur passed through the large room. Single voices were heard, exclaiming: "Shall we submit to that?--Knock him down!--Don't let him get away alive!"

They crowded around him; fierce cries and low mutterings were heard on all sides; Oswald was looking for the one whose turn it was to be next.

Suddenly Oldenburg stood by his side.

"How, gentlemen!" he exclaimed, raising himself to his full stately height; "twenty against one! The odds are too unfair in all conscience. Perhaps you would like to call in a few servants to help you!"

His words acted like a charm. Everybody saw at once the disgraceful scene in its true light. The more sensible felt obliged to the baron for having saved them from the disgrace in which they would have been involved a minute later. A few only seemed to take his interference amiss.

"The matter does not concern you, baron," cried Grieben, angrily.

"Pardon me, Count Grieben," replied Oldenburg; "the matter does concern me in two ways. First, because I think it is every gentleman's duty to see that such affairs are carried out, I will not say decently, but at least honestly; and secondly, because I have the honor of calling Dr. Stein my friend. If you or any of your friends here desire to hold me to an account for what I have said, I am at your service. In the mean time, however, I beg you will allow me to arrange the difficulty of my friend, Doctor Stein, in a manner fit for gentlemen. I shall be back here in a few moments, to place myself at your disposal. You will give me your arm, Doctor Stein?"

The baron took Oswald's arm into his, and led him out of the room, through the midst of the young noblemen, who readily made way for him.
