work in the practical class. Cullingworth saw his
chance, and acted on the instant. Slipping out of the
classroom, he threw open the ice-chest, rolled his ulster
round the dreadful glistening mass, closed the chest
again, and walked quietly away. I have no doubt that to
this day the disappearance of that waxy liver is one of
the most inexplicable mysteries in the career of our
Professor.

That evening, and for many evenings to come, we
worked upon our liver. For our experiments it was
necessary to subject it all to great heat in an endeavour
to separate the nitrogenous cellular substance from the
non-nitrogenous waxy matter. With our limited appliances
the only way we could think of was to cut it into fine
pieces and cook it in a frying pan. So night after night
the curious spectacle might have been seen of a beautiful
young woman and two very earnest young men busily engaged
in making these grim fricassees. Nothing came of all our
work; for though Cullingworth considered that he had
absolutely established his case, and wrote long screeds
to the medical papers upon the subject, he was never apt
at stating his views with his pen, and he left, I am

At the end of the year we both passed our
