menage. Cullingworth had a fad at the time, that all
the diseases of civilisation were due to the abandonment
of the open-air life of our ancestors, and as a corollary
he kept his windows open day and night. As his wife was
obviously fragile, and yet would have died before she
would have uttered a word of complaint, I took it upon
myself to point out to him that the cough from which she
suffered was hardly to be cured so long as she spent her
life in a draught. He scowled savagely at me for my
interference; and I thought we were on the verge of a
quarrel, but it blew over, and he became more considerate
in the matter of ventilation.

Our evening occupations just about that time were of
a most extraordinary character. You are aware that there
is a substance, called waxy matter, which is deposited in
the tissues of the body during the course of certain
diseases. What this may be and how it is formed has been
a cause for much bickering among pathologists.
Cullingworth had strong views upon the subject, holding
that the waxy matter was really the same thing as the
glycogen which is normally secreted by the liver. But it
is one thing to have an idea, and another to be able to
prove it. Above all, we wanted some waxy matter with
which to experiment. But fortune favoured us in the most
magical way. The Professor of Pathology had come into
possession of a magnificent specimen of the condition.
With pride he exhibited the organ to us in the class-room
before ordering his assistant to remove it to the ice-
chest, preparatory to its being used for microscopical
