They passed into the adjoining room.

Thus the two men came into a high-ceiled apartment, cylindrical in shape, with plastered walls painted green everywhere save for the quaint embellishment of a large oval, wherein a woman, having an eagle's beak, grasped in one hand a serpent and in the other a knife. Sir Thomas Browne seemed to recognize this curious design, and gave an ominous nod.

Borsdale said: "You see Dr. Herrick had prepared everything. And much of what we are about to do is merely symbolical, of course. Most people undervalue symbols. They do not seem to understand that there could never have been any conceivable need of inventing a periphrasis for what did not exist."

Sir Thomas Browne regarded Borsdale for a while intently. Then the knight gave his habitual shrugging gesture. "You are braver than I, Philip, because you are more ignorant than I. I have been too long an amateur of the curious. Sometimes in over-credulous moments I have almost believed that in sober verity there are reasoning beings who are not human—beings that for their own dark purposes seek union with us. Indeed, I went into Pomerania once to talk with John Dietrick of Ramdin. He told me one of those relations whose truth we dread, a tale which I did not dare, I tell you candidly, even to discuss in my Vulgar Errors. Then there is Helgi Thorison's history, and that of Leonard of Basle also. Oh, there are more recorded stories of this nature than you dream of, Philip. We have only the choice between believing that all these men were madmen, and believing that ordinary human life is led by a drugged animal who drowses through a purblind existence among merciful veils. And these female creatures—these Corinnas, Perillas, Myrhas, and Electras—can it be possible that they are always striving, for their own strange ends, to rouse the sleeping animal and break the kindly veils?—and are they permitted to use such amiable enticements as Herrick describes? Oh, no, all this is just a madman's dream, dear lad, and we must not dare to consider it seriously, lest we become no more sane than he."

"But you will aid me?" Borsdale said.

"Yes, I will aid you, Philip, for in Herrick's case I take it that the mischief is consummated already; and we, I think, risk nothing worse than death. But you will need another knife a little later—a knife that will be clean."

"I had forgotten." Borsdale withdrew, and presently returned with a bone-handled knife. And then he made a light. "Are you quite ready, sir?"

Sir Thomas Browne, that aging amateur of the curious, could not resist a laugh.

And then they sat about proceedings of which, for obvious reasons, the details are best left unrecorded. It was not an unconscionable while before they seemed to be aware of unusual phenomena. But as Sir Thomas always pointed out, in subsequent discussions, these were quite possibly the fruitage of excited imagination.

"Now, Philip!—now, give me the knife!" cried Sir Thomas Browne. He knew for the first time, despite many previous mischancy happenings, what real terror was.
