Master Thaddeus, as he was instructing his medical scholars, propounded
that whoever should continue for nine days to eat egg-plant [71] would
go mad.
And he proved it according to the law of psychic [72].
One of his scholars, hearing this lesson, decided to put it to the
test. He began to eat egg-plant, and at the end of nine days went
before his master and said: master, that lesson you read us is not
true, because I have put it to the test, and I am not mad.
And he rose and showed him his behind.
Write, said the master, that all this about the egg-plant has been
proved, and he wrote a fresh essay on the subject.
