“Why, I myself am an instance of a man who had a strange belief. Indeed, it was no wonder that my friends were alarmed, and insisted on my being put under control.

At times I held the belief so strongly that I actually tried to take human life. The doctor here will bear me out that on one occasion I tried to kill him for the purpose of strengthening my vital powers by the assimilation with my own body of his life through the medium of his blood⁠—relying, of course, upon the Scriptural phrase, ‘For the blood is the life.’ Though, indeed, the vendor of a certain nostrum has vulgarised the truism to the very point of contempt.
