Pratt-Haldane was most amiable, and listened with all politeness to my story.  But when I looked at his heavy set features, his slow eyes, and the ponderous study furniture which surrounded him, I could hardly tell him what I had come to say.  It was all so substantial, so material.  And, besides, what would I myself have said a short month ago if one of my colleagues had come to me with a story of demonic possession?  Perhaps.  I should have been less patient than he was.  As it was, he took notes of my statement, asked me how much tea I drank, how many hours I slept, whether I had been overworking much, had I had sudden pains in the head, evil dreams, singing in the ears, flashes before the eyes—­all questions which pointed to his belief that brain congestion was at the bottom of my trouble.  Finally he dismissed me with a great many platitudes about open-air exercise, and avoidance of nervous excitement.  His prescription, which was for chloral and bromide, I rolled up and threw into the gutter.

No, I can look for no help from any human being.  If I consult any more, they may put their heads together and I may find myself in an asylum.  I can but grip my courage with both hands, and pray that an honest man may not be abandoned.

April 10.  It is the sweetest spring within the memory of man.  So green, so mild, so beautiful!  Ah, what a contrast between nature without and my own soul so torn with doubt and terror!  It has been an uneventful day, but I know that I am on the edge of an abyss.  I know it, and yet I go on with the routine of my life.  The one bright spot is that Agatha is happy and well and out of all danger.  If this creature had a hand on each of us, what might she not do?

April 16.  The woman is ingenious in her torments.  She knows how fond I am of my work, and how highly my lectures are thought of.  So it is from that point that she now attacks me.  It will end, I can see, in my losing my professorship, but I will fight to the finish.  She shall not drive me out of it without a struggle.

I was not conscious of any change during my lecture this morning save that for a minute or two I had a dizziness and swimminess which rapidly passed away.  On the contrary, I congratulated myself upon having made my subject (the functions of the red corpuscles) both interesting and clear.  I was surprised, therefore, when a student came into my laboratory immediately after the lecture, and complained of being puzzled by the discrepancy between my statements and those in the text books.  He showed me his note-book, in which I was reported as having in one portion of the lecture championed the most outrageous and unscientific heresies.  Of course I denied it, and declared that he had misunderstood me, but on comparing his notes with those of his companions, it became clear that he was right, and that I really had made some most preposterous statements.  Of course I shall explain it away as being the result of a moment of aberration, but I feel only too sure that it will be the first of a series.  It is but a month now to the end of the session, and I pray that I may be able to hold out until then.
