This was on the left-hand wall as one entered the room. The right-hand wall was no less thickly inscribed, and Willett felt a start of recognition when he came up the pair of formulae so frequently occurring in the recent notes in the library. They were, roughly speaking, the same; with the ancient symbols of "Dragon's Head" and "Dragon's Tail" heading them as in Ward's scribblings. But the spelling differed quite widely from that of the modern versions, as if old Curwen had had a different way of recording sound, or as if later study had evolved more powerful and perfected variants of the invocations in question. The doctor tried to reconcile the chiselled version with the one which still ran persistently in his head, and found it hard to do. Where the script he had memorised began "Y'ai 'ng'ngah, Yog-Sothoth", this epigraph started out as "Aye, engengah, Yogge-Sothotha"; which to his mind would seriously interfere with the syllabification of the second word.
Ground as the later text was into his consciousness, the discrepancy disturbed him; and he found himself chanting the first of the formulae aloud in an effort to square the sound he conceived with the letters he found carved. Weird and menacing in that abyss of antique blasphemy rang his voice; its accents keyed to a droning sing-song either through the spell of the past and the unknown, or through the hellish example of that dull, godless wail from the pits whose inhuman cadences rose and fell rhythmically in the distance through the stench and the darkness.
Y'AI 'NG'NGAH, YOG-SOTHOTH H'EE-L'GEB F'AI THRODOG UAAAH!
But what was this cold wind which had sprung into life at the very outset of the chant? The lamps were sputtering woefully, and the gloom grew so dense that the letters on the wall nearly faded from sight. There was smoke, too, and an acrid odour which quite drowned out the stench from the far-away wells; an odour like that he had smelt before, yet infinitely stronger and more pungent. He turned from the inscriptions to face the room with its bizarre contents, and saw that the kylix on the floor, in which the ominous efflorescent powder had lain, was giving forth a cloud of thick, greenish-black vapour of surprising volume and opacity. That powder – Great God! it had come from the shelf of "Materia" – what was it doing now, and what had started it? The formula he had been chanting – the first of the pair – Dragon's Head, ascending node – Blessed Saviour, could it be …
The doctor reeled, and through his head raced wildly disjointed scraps from all he had seen, heard, and read of the frightful case of Joseph Curwen and Charles Dexter Ward. "I say to you againe, doe not call up Any that you can not put downe … Have ye Wordes for laying at all times readie, and stopp not to be sure when there is any Doubte of Whom you have … 3 Talkes with What was therein inhum'd …" Mercy of Heaven, what is that shape behind the parting smoke?

Marinus Bicknell Willett has not hope that any part of his tale will be believed except by certain sympathetic friends, hence he has made no attempt to tell it beyond his most intimate circle. Only a few outsiders have ever heard it repeated, and of these the majority laugh and remark that the doctor surely is getting old. He has been advised to take a long vacation and to shun future cases dealing with mental disturbance. But Mr. Ward knows that the veteran physician speaks only a horrible truth. Did not he himself see the noisome aperture in the bungalow cellar? Did not Willett send him home overcome and ill at eleven o'clock that portentous morning? Did he not telephone the doctor in vain that evening, and again the next day, and had he not driven to the bungalow itself on that following noon, finding his friend unconscious but unharmed on one of the beds upstairs? Willett had been breathing stertorously, and opened his eyes slowly when Mr. Ward gave him some brandy fetched from the car. Then he shuddered and screamed, crying out, 'That beard… those eyes… God, who are you?' A very strange thing to say to a trim, blue-eyed, clean-shaven gentleman whom he had known from the latter's boyhood.
In the bright noon sunlight the bungalow was unchanged since the previous morning. Willett's clothing bore no disarrangement beyond certain smudges and worn places at the knees, and only a faint acrid odour reminded Mr. Ward of what he had smelt on his son that day he was taken to the hospital. The doctor's flashlight was missing, but his valise was safely there, as empty as when he had brought it. Before indulging in any explanations, and obviously with great moral effort, Willett staggered dizzily down to the cellar and tried the fateful platform before the tubs. It was unyielding. Crossing to where he had left his yet unused tool satchel the day before, he obtained a chisel and began to pry up the stubborn planks one by one. Underneath the smooth concrete was still visible, but of any opening or perforation there was no longer a trace. Nothing yawned this time to sicken the mystified father who had followed the doctor downstairs; only the smooth concrete underneath the planks – no noisome well, no world of subterrene horrors, no secret library, no Curwen papers, no nightmare pits of stench and howling, no laboratory or shelves or chiselled formulae, no… Dr. Willett turned pale, and clutched at the younger man. 'Yesterday,' he asked softly, 'did you see it here … and smell it?' And when Mr. Ward, himself transfixed with dread and wonder, found strength to nod an affirmative, the physician gave a sound half a sigh and half a gasp, and nodded in turn. 'Then I will tell you', he said.
So for an hour, in the sunniest room they could find upstairs, the physician whispered his frightful tale to the wondering father. There was nothing to relate beyond the looming up of that form when the greenish-black vapour from the kylix parted, and Willett was too tired to ask himself what had really occurred. There were futile, bewildered head-shakings from both men, and once Mr. Ward ventured a hushed suggestion, 'Do you suppose it would be of any use to dig?' The doctor was silent, for it seemed hardly fitting for any human brain to answer when powers of unknown spheres had so vitally encroached on this side of the Great Abyss. Again Mr. Ward asked, 'But where did it go? It brought you here, you know, and it sealed up the hole somehow.' And Willett again let silence answer for him.
But after all, this was not the final phase of the matter. Reaching for his handkerchief before rising to leave, Dr. Willett's fingers closed upon a piece of paper in his pocket which had not been there before, and which was companioned by the candles and matches he had seized in the vanished vault. It was a common sheet, torn obviously from the cheap pad in that fabulous room of horror somewhere underground, and the writing upon it was that of an ordinary lead pencil – doubtless the one which had lain beside the pad. It was folded very carelessly, and beyond the faint acrid scent of the cryptic chamber bore no print or mark of any world but this. But in the text itself it did indeed reek with wonder; for here was no script of any wholesome age, but the laboured strokes of mediaeval darkness, scarcely legible to the laymen who now strained over it, yet having combinations of symbols which seemed vaguely familiar. The briefly scrawled message was this, and its mystery lent purpose to the shaken pair, who forthwith walked steadily out to the Ward car and gave orders to be driven first to a quiet dining place and then to the John Hay Library on the hill.
