She came now and took complete possession of him, as before he had ascended to the tower. "But if I didn't love you would I have come to you?" That sentence which she had spoken, with a caressing inflection of the voice, he heard again, and again he saw her mocking and tender face.

"Ah, you are dreaming," said Des Hermies, tapping him on the shoulder. "We have to go. It's striking ten."

When they were in the street they said good night to Gévingey, who lived on the other side of the river. Then they walked along a little way.

"Well," said Des Hermies, "are you interested in my astrologer?"

"He is slightly mad, isn't he?"

"Slightly? Humph."

"Well, his stories are incredible."

"Everything is incredible," said Des Hermies placidly,

turning up the collar of his overcoat. "However, I will admit that Gévingey astounds me when he asserts that he was visited by a succubus. His good faith is not to be doubted, for I know him to be a man who means what he says, though he is vain and doctorial. I know, too, that at La Salpêtrière such occurrences are not rare. Women smitten with hystero-epilepsy see phantoms beside them in broad daylight and mate with them in a cataleptic state, and every night couch with visions that must be exactly like the fluid creatures of incubacy. But these women are hystero-epileptics, and Gévingey isn't, for I am his physician. Then, what can be believed and what can be proved? The materialists have taken the trouble to revise the accounts of the sorcery trials of old. They have found in the possession-cases of the Ursulines of Loudun and the nuns of Poitiers, in the history, even, of the convulsionists of Saint Médard, the symptoms of major hysteria, the same contractions of the whole system, the same muscular dissolutions, the same lethargies, even, finally, the famous arc of the circle. And what does this demonstrate, that these demonomaniacs were hystero-epileptics? Certainly. The observations of Dr. Richet, expert in such matters, are conclusive, but wherein do they invalidate possession? From the fact that the patients of La Salpêtrière are not possessed, though they are hysterical, does it follow that others, smitten with the same malady as they, are not possessed? It would have to be demonstrated also that all demonopathics are hysterical, and that is false, for there are women of sound mind and perfectly good sense who are demonopathic without knowing it. And admitting that the last point is controvertible, there remains this unanswerable question: is a woman possessed because she is hysterical, or is she hysterical because she is possessed? Only the Church can answer. Science cannot.

"No, come to think it over, the effrontery of the positivists is appalling. They decree that Satanism does not exist. They lay everything at the account of major hysteria, and they
