position. I
have a large new note-book which shall be devoted entirely to
scientific detail.

Long talk with Agatha and Mrs. Marden in the evening about our
marriage. We think that the summer vac. (the beginning of it) would
be the best time for the wedding. Why should we delay? I grudge even
those few months. Still, as Mrs. Marden says, there are a good many
things to be arranged.

March 28. Mesmerized again by Miss Penclosa. Experience much the same
as before, save that insensibility came on more quickly. See Note-book
A for temperature of room, barometric pressure, pulse, and respiration
as taken by Professor Wilson.

March 29. Mesmerized again. Details in Note-book A.

March 30. Sunday, and a blank day. I grudge any interruption of our
experiments. At present they merely embrace the physical signs which
go with slight, with complete, and with extreme insensibility.
Afterward we hope to pass on to the phenomena of suggestion and of
lucidity. Professors have demonstrated these things upon women at
Nancy and at the Salpetriere. It will be more convincing when a woman
demonstrates it upon a professor, with a second professor as a witness.
And that I should be the subject--I, the sceptic, the materialist! At
least, I have shown that my devotion to science is greater than to my
own personal consistency. The eating of our own words is the greatest
sacrifice which truth ever requires of us.

My neighbor, Charles Sadler, the handsome young demonstrator of
anatomy, came in this evening to return a volume of Virchow's
"Archives" which I had lent him. I call him young, but, as a matter of
fact, he is a year older than I am.

"I understand, Gilroy," said he, "that you are being experimented upon
by Miss Penclosa."

"Well," he went on, when I had acknowledged it, "if I were you, I
should not let it go any further. You will think me very impertinent,
no doubt, but, none the less, I feel it to be my duty to advise you to
have no more to do with her."

Of course I asked him why.

"I am so placed that I cannot enter into particulars as freely as I
could wish," said he. "Miss Penclosa is the friend of my friend, and
my position is a delicate one. I can only say this: that I have myself
been the subject of some of the woman's experiments, and that they have
left a most unpleasant impression upon my mind."

He could hardly expect me to be satisfied with that, and I tried hard
to get something more defi
