_1 October._--It was towards noon when I was awakened by the Professor walking into my room. He was more jolly and cheerful than usual, and it is quite evident that last night's work has helped to take some of the brooding weight off his mind. After going over the adventure of the night he suddenly said:--

"Your patient interests me much. May it be that with you I visit him this morning? Or if that you are too occupy, I can go alone if it may be. It is a new experience to me to find a lunatic who talk philosophy, and reason so sound." I had some work to do which pressed, so I told him that if he would go alone I would be glad, as then I should not have to keep him waiting; so I called an attendant and gave him the necessary instructions. Before the Professor left the room I cautioned him against getting any false impression from my patient. "But," he answered, "I want him to talk of himself and of his delusion as to consuming live things. He said to Madam Mina, as I see in your diary of yesterday, that he had once had such a belief. Why do you smile, friend John?"

"Excuse me," I said, "but the answer is here." I laid my hand on the type-written matter. "When our sane and learned lunatic made that very statement of how he _used_ to consume life, his mouth was actually nauseous with the flies and spiders which he had eaten just before Mrs. Harker entered the room." Van Helsing smiled in turn. "Good!" he said. "Your memory is true, friend John. I should have remembered. And yet it is this very obliquity of thought and memory which makes mental disease such a fascinating study. Perhaps I may gain more knowledge out of the folly of this madman than I shall from the teaching of the most wise. Who knows?" I went on with my work, and before long was through that in hand. It seemed that the time had been very short indeed, but there was Van Helsing back in the study. "Do I interrupt?" he asked politely as he stood at the door.

"Not at all," I answered. "Come in. My work is finished, and I am free. I can go with you now, if you like.

"It is needless; I have seen him!"

"Well?"
