these are! Results, results, results—and the cause an absolute mystery. It is stimulating to the imagination, but I must be on my guard against that. Let us have no inferences nor deductions, and nothing but solid facts. I KNOW that the mesmeric trance is true; I KNOW that mesmeric suggestion is true; I KNOW that I am myself sensitive to this force. That is my present 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 definite out of him, but without success. Is it conceivable that he could be jealous at my having superseded him? Or is he one of those men of science who feel personally injured when facts run counter to their preconceived opinions? He cannot seriously suppose that because he has some vague grievance I am, therefore, to abandon a series of experiments which promise to be so fruitful of results. He appeared to be annoyed at the light way in which I treated his shadowy warnings, and we parted with some little coldness on both sides.

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. Her brightness when I come, her dejection when I go, her eagerness that I should come often, the expression of her eyes, the tone of her voice—I tried to think that they meant nothing, and were, perhaps, only her ardent West Indian manner. But last night, as I awoke from the mesmeric sleep, I put out my hand, unconsciously, involuntarily, and clasped hers. When I came fully to myself, we were sitting with them locked, she looking up at me with an expectant smile. And the horrible thing was that I felt impelled to say what she expected me to say. What a false wretch I should have been! How I should have loathed myself to-day had I yielded to the temptation of that moment! But, thank God, I was strong enough to spring up and hurry from the room. I was rude, I fear, but I could not, no, I COULD not, trust myself another moment. I, a gentleman, a man of honor, engaged to one of the sweetest girls in England—and yet in a moment of reasonless passion I nearly professed love for this woman whom I hardly know. She is far older than myself and a cripple. It is monstrous, odious; and yet the impulse was so strong that, had I stayed another minute in her presence, I should have committed myself. What was it? I have to teach others the workings of our organism, and what do I know of it myself? Was it the sudden upcropping of some lower stratum in my nature—a brutal primitive instinct suddenly asserting itself? I could almost believe the tales of obsession by evil spirits, so overmastering was the feeling.

Well, the incident places me in a most unfortunate position. On the one hand, I am very loath to abandon a series of experiments which have already gone so far, and which promise such brilliant results. On the other, if this unhappy woman has conceived a passion for me—— But surely even now I must have made some hideous mistake. She, with her age and her deformity! It is impossible. And then she knew about Agatha. She understood how I was placed. She only smiled out of amusement, perhaps, when in my dazed state I seized her hand. It was my half-mesmerized brain which gave it a meaning, and sprang with such bestial swiftness to meet it. I wish I could persuade myself that it was indeed so. On the whole, perhaps, my wisest plan would be to postpone our other experiments until Wilson's return. I have written a note to Miss Penclosa, therefore, making no allusion to last night, but saying that a press of work would cause me to interrupt our sittings for a few days. She has answered, formally enough, to say that if I should change my mind I should find her at home at the usual hour.

10 P. M. Well, well, what a thing of straw I am! I am coming to know myself better of late, and the more I know the lower I fall in my own estimation. Surely I was not always so weak as this. At four o'clock I should have smiled had
