While all this festivity had been going on at the Grüner Mann, a very different scene had been enacted elsewhere. Young Fritz von Hartmann, with a solemn face and a reserved manner, had, after the experiment, consulted and adjusted some mathematical instruments; after which, with a few peremptory words to the janitor, he had walked out into the street and wended his way slowly in the direction of the house of the Professor. As he walked he saw Von Althaus, the professor of anatomy, in front of him, and quickening his pace he overtook him. “I say, Von Althaus,” he exclaimed, tapping him on the sleeve, “you were asking me for some information the other day concerning the middle coat of the cerebral arteries. Now I find----” “Donnerwetter!” shouted Von Althaus, who was a peppery old fellow. “What the deuce do you mean by your impertinence! I’ll have you up before the Academical Senate for this, sir”; with which threat he turned on his heel and hurried away. Von Hartmann was much surprised at this reception. “It’s on account of this failure of my experiment,” he said to himself, and continued moodily on his way. Fresh surprises were in store for him, however. He was hurrying along when he was overtaken by two students. These youths, instead of raising their caps or showing any other sign of respect, gave a wild whoop of delight the instant that they saw him, and rushing at him, seized him by each arm and commenced dragging him along with them. “Gott in Himmel!” roared Von Hartmann. “What is the meaning of this unparalleled insult? Where are you taking me?” “To crack a bottle of wine with us,” said the two students. “Come along! That is an invitation which you have never refused.” “I never heard of such insolence in my life!” cried Von Hartmann. “Let go my arms! I shall certainly have you rusticated for this. Let me go, I say!” and he kicked furiously at his captors. “Oh, if you choose to turn ill-tempered, you may go where you like,” the students said, releasing him. “We can do very well without you.” “I know you. I’ll pay you out,” said Von Hartmann furiously, and continued in the direction which he imagined to be his own home, much incensed at the two episodes which had occurred to him on the way.
