and demonstrating to you the result." This address, coming
from so young a student, caused considerable astonishment among the
audience, and some were inclined to be offended, thinking that he
assumed rather too much importance. The majority, however, looked upon
him as a young man of great promise, and many comparisons were made as
they left the hall between his dignified conduct and the levity of
his professor, who during the above remarks was laughing heartily in a
corner, by no means abashed at the failure of the experiment.

Now although all these learned men were filing out of the lecture-room
under the impression that they had seen nothing of note, as a matter of
fact one of the most wonderful things in the whole history of the world
had just occurred before their very eyes Professor von Baumgarten had
been so far correct in his theory that both his spirit and that of his
pupil had been for a time absent from his body. But here a strange and
unforeseen complication had occurred. In their return the spirit of
Fritz von Hartmann had entered into the body of Alexis von Baumgarten,
and that of Alexis von Baumgarten had taken up its abode in the frame of
Fritz von Hartmann. Hence the slang and scurrility which issued from
the lips of the serious Professor, and hence also the weighty words

Fritz within was reckless at the thought of the bride whom he had won so
easily. His first impulse was to go up to the house and see her, but on
second thoughts he came to the conclusion that it would be best to stay
away until Madame Baumgarten should be informed by her husband of the
agreement which had been made. He therefore made his way down to the
Graner Mann, which was one of the favourite trysting-places of the
wilder students, and ran, boisterously waving his cane in the air, into
the little parlour, where sat Spiegler and Muller and half a dozen other
boon companions.

"Ha, ha! my boys," he shouted. "I knew I should find you here. Drink
up, every one of you, and call for what you like, for I'm going to stand
treat to-day."
