purpose? The idea that I was bound for some den of thieves where I
might be robbed and possibly murdered, I dismissed with a smile. Thieves
do not make elaborately concerted plans to rob poor devils like me.
Poverty has its compensations in that respect. But there were other
possibilities. Imagination backed by experience had no difficulty in
conjuring up a number of situations in which a medical man might be
called upon, with or without coercion, either to witness or actively to

Reflections of this kind occupied me pretty actively if not very
