os. Then my perception
grew clear and minute as though I saw things in a concave mirror. His
manner seemed to have changed into something nervous and hasty. He pulled
out his watch and grimaced at it. "Eleven-seven! And to-night I must--
Seven-twenty-five. Waterloo! I must go at once." He called for the bill,
and struggled with his coat. Officious waiters came to our assistance. In
another moment I was wishing him good-bye, over the apron of a cab, and
still with an absurd feeling of minute distinctness, as though--how can I
express it?--I not only saw but _felt_ through an inverted
opera-glass.

"That stuff," he said. He put his hand to his forehead. "I ought not to
have given it to you. It will make your head split to-morrow. Wait a
minute. Here." He handed me out a little flat thing like a seidlitz-powder.
"Take that in water as you are going to bed. The other thing was a
drug. Not till you're ready to go to bed, mind. It will clear your head.
That's all. One more shake--Futurus!"

I gripped his shrivelled claw. "Good-bye," he said, and by the droop of
his eyelids I judged he too was a little under the influence of that
brain-twisting cordial.

He recollected something else with a start, felt in his breast-pocket, and
produced another packet, this time a cylinder the size and shape of a
shaving-stick. "Here," said he. "I'd almost forgotten. Don't open this

It was so heavy that I wellnigh dropped it. "All ri'!" said I, and he
grinned at me through the cab window as the cabman flicked his horse into
wakefulness. It was a white packet he had given me, with red seals at
either end and along its edge. "If this isn't money," said I, "it's
platinum or lead."

I stuck it with elaborate care into my pocket, and with a whirling brain
walked home through the Regent Street loiterers and the dark back streets
beyond Portland Road. I remember the sensations of that walk very vividly,
strange as they were. I was still so far myself that I could notice my
strange mental state, and wonder whether this stuff I had had was opium--a
drug beyond my experience. It is hard now to describe the peculiarity of
my mental strangeness--mental doubling vaguely expresses it. As I was
walking up Regent Street I found in my mind a queer persuasion that it
was Waterloo Station, and had an odd impulse to get into the Polytechnic
as a man might get into a train. I put a knuckle in my eye, and it was
