‘You left off your beard and glasses and fooled the guards around the house. They thought it was he who went in, and they thought it was he who came out when you had strangled and hidden him. But you hadn’t reckoned on the different contents of two minds. You were a fool, Joseph Curwen, to fancy that a mere visual ident-ity would be enough. Why didn’t you think of the speech and the voice and the handwriting? It hasn’t worked, you see, after all. You know better than I who or what wrote that message in minuscules, but I will warn you it was not written in vain. There are abominations and blasphemies which must be stamped out, and I believe that the writer of those words will attend to Orne and Hutchinson. One of those creatures wrote you once, ‘do not call up any that you cannot put down’. You were undone once before, perhaps in that very way, and it may be that your own evil magic will undo you all again. Curwen, a man can’t tamper with Nature beyond certain limits, and every horror you have woven will rise up to wipe you out.’

But here the doctor was cut short by a convulsive cry from the creature before him. Hopelessly at bay, weaponless, and knowing that any show of physical violence would bring a score of attendants to the doctor’s rescue, Joseph Curwen had recourse to his one ancient ally, and began a series of cabbalistic motions with his forefingers as his deep, hollow voice, now unconcealed by feigned hoarseness, bellowed out the opening words of a terrible formula.

PER ADONAI ELOIM, ADONAI JEHOVA,
ADONAI SABAOTH, METRATON . . .

But Willett was too quick for him. Even as the dogs in the yard outside began to howl, and even as a chill wind sprang suddenly up from the bay, the doctor commenced the solemn and measured intonation of that which he had meant all along to recite. An eye for an eye – magic for magic – let the outcome shew how well the lesson of the abyss had been learned! So in a clear voice Marinus Bicknell Willett began the second of that pair of formulae whose first had raised the writer of those minuscules – the cryptic invocation whose heading was the Dragon’s Tail, sign of the descending node –

OGTHROD AI’F GEB’L-EE’H YOG-SOTHOTH ‘NGAH’NG AI’Y ZHRO!

At the very first word from Willett’s mouth the previously commenced formula of the patient stopped short. Unable to speak, the monster made wild motions with his arms until they too were arrested. When the awful name of Yog-Sothoth was uttered, the hideous change began. It was not merely a dissolution, but rather a transformation or recapitulation; and Willett shut his eyes lest he faint before the rest of the incantation could be pronounced.
