March 31. Mesmerized by Miss P.

April 1. Mesmerized by Miss P. (Note-book A.)

April 2. Mesmerized by Miss P. (Sphygmographic chart taken by Professor Wilson.)

April 3. It is possible that this course of mesmerism may be a little trying to the general constitution. Agatha says that I am thinner and darker under the eyes. I am conscious of a nervous irritability which I had not observed in myself before. The least noise, for example, makes me start, and the stupidity of a student causes me exasperation instead of amusement. Agatha wishes me to stop, but I tell her that every course of study is trying, and that one can never attain a result with out paying some price for it. When she sees the sensation which my forthcoming paper on "The Relation between Mind and Matter" may make, she will understand that it is worth a little nervous wear and tear. I should not be surprised if I got my F. R. S. over it.

Mesmerized again in the evening. The effect is produced more rapidly now, and the subjective visions are less marked. I keep full notes of each sitting. Wilson is leaving for town for a week or ten days, but we shall not interrupt the experiments, which depend for their value as much upon my sensations as on his observations.

April 4. I must be carefully on my guard. A complication has crept into our experiments which I had not reckoned upon. In my eagerness for scientific facts I have been foolishly blind to the human relations between Miss Penclosa and myself. I can write here what I would not breathe to a living soul. The unhappy woman appears to have formed an attachment for me.

I should not say such a thing, even in the privacy of my own intimate journal, if it had not come to such a pass that it is impossible to ignore it. For some time,-that is, for the last week,-there have been signs which I have brushed aside and refused to think of.
