see their practical bearing upon medical science. This is, however, by
no means the proper place for displaying the proofs and discussing the
consequences of this too generally unrecognized state of facts.

In pursuance of my habit, I was covertly observing Mr. Jennings, with
all my caution--I think he perceived it--and I saw plainly that he was
as cautiously observing me. Lady Mary happening to address me by my
name, as Dr. Hesselius, I saw that he glanced at me more sharply, and
then became thoughtful for a few minutes.

After this, as I conversed with a gentleman at the other end of the
room, I saw him look at me more steadily, and with an interest which I
thought I understood. I then saw him take an opportunity of chatting
with Lady Mary, and was, as one always is, perfectly aware of being the
subject of a distant inquiry and answer.

This tall clergyman approached me by-and-by; and in a little time we had
got into conversation. When two people, who like reading, and know books
and places, having travelled, wish to discourse, it is very strange if
they can't find topics. It was not accident that brought him near me,
and led him into conversation. He knew German and had read my Essays on
Metaphysical Medicine which suggest more than they actually say.

This courteous man, gentle, shy, plainly a man of thought and reading,
who moving and talking among us, was not altogether of us, and whom I
already suspected of leading a life whose transactions and alarms were
carefully concealed, with an impenetrable reserve from, not only the
world, but his best beloved friends--was cautiously weighing in his own
mind the idea of taking a certain step with regard to me.
