taste was not unpleasant; and, as it gave rise to no
immediate effects, I leaned back in my chair and composed myself for
what was to come. Mr. Abrahams seated himself beside me, and I felt
that he was watching my face from time to time while repeating some
more of the invocations in which he had indulged before.

A sense of delicious warmth and languor began gradually to steal over
me, partly, perhaps, from the heat of the fire, and partly from some
unexplained cause. An uncontrollable impulse to sleep weighed down my
eyelids, while, at the same time, my brain worked actively, and a
hundred beautiful and pleasing ideas flitted through it. So utterly
lethargic did I feel that, though I was aware that my companion put his
hand over the region of my heart, as if to feel how it were beating, I
did not attempt to prevent him, nor did I even ask him for the reason
of his action. Everything in the room appeared to be reeling slowly
round in a drowsy dance, of which I was the centre. The great elk's
head at the far end wagged solemnly backward and forward, while the
massive salvers on the tables performed cotillons with the claret
cooler and the epergne. My head fell upon my breast from sheer
heaviness, and I should have become unconscious had I not been recalled
to myself by the opening of the door at the other end of the hall.

This door led on to the raised dais, which, as I have mentioned, the
heads of the house used to reserve for their own use. As it swung
slowly back upon its hinges, I sat up in my chair, clutching at the
arms, and staring with a horrified glare at the dark passage outside.
Something was coming down it--something unformed and intangible, but
still a _something_. Dim and shadowy, I saw it flit across the
threshold, while a blast of ice-cold air swept down the room, which
seemed to blow through me, chilling my very heart. I was aware of the
mysterious presence, and then I heard it speak in a voice like the
sighing of an east wind among pine-trees on the banks of a desolate
sea.

It said: "I am the invisible nonentity. I have affinities and am
subtle. I am electric, magnetic, and spiritualistic. I am the great
ethereal sigh-heaver. I kill dogs. Mortal, wilt thou choose me?"

I was about to speak, but the words seemed to be choked in my throat;
and, before I could get them out, the shadow flitted across the hall
and vanished in the darkness at the other side, while a long-drawn
melancholy sigh quivered
