Then I heard the wrench of the adze, and the woodwork split and cracked under it, and with a loud crash the door suddenly burst open; and for a moment we started back aghast at a fearful screaming cry, no human voice, but as the roar of a monster, that burst forth inarticulate and struck at us out of the darkness. "Hold the lamp," said the doctor, and we went in and glanced quickly round the room. "There it is," said Dr. Haberden, drawing a quick breath; "look, in that corner." I looked, and a pang of horror seized my heart as with a white-hot iron. There upon the floor was a dark and putrid mass, seething with corruption and hideous rottenness, neither liquid nor solid, but melting and changing before our eyes, and bubbling with unctuous oily bubbles like boiling pitch. And out of the midst of it shone two burning points like eyes, and I saw a writhing and stirring as of limbs, and something moved and lifted up that might have been an arm. The doctor took a step forward, and raised the iron bar and struck at the burning points, and drove in the weapon, and struck again and again in a fury of loathing. At last the thing was quiet. * * * * * A week or two later, when I had to some extent recovered from the terrible shock, Dr. Haberden came to see me. "I have sold my practice," he began, "and to-morrow I am sailing on a long voyage. I do not know whether I shall ever return to England; in all probability I shall buy a little land in California, and settle there for the remainder of my life. I have brought you this packet, which you may open and read when you feel able to do so. It contains the report of Dr. Chambers on what I submitted to him. Good-bye, Miss Leicester, good-bye." When he was gone, I opened the envelope; I could not wait, and proceeded to read the papers within. Here is the manuscript; and if you will allow me, I will read you the astounding story it contains. "My dear Haberden," the letter began, "I have delayed inexcusably in answering your questions as to the white substance you sent me. To tell you the truth, I have hesitated for some time as to what course I should adopt, for there is a bigotry and an orthodox standard in physical science as in theology, and I knew that if I told you the truth I should offend rooted prejudices which I once held dear myself. However, I have determined to be plain with you, and first I must enter into a short personal explanation.
