nd that it had not perceptibly diminished in
power.

The idea was not at all pleasant to him, and very naturally his thoughts
turned back once more to his cosy home that had been on the edge of
Wimbledon Common ten thousand years ago. He remembered, with a curious
sort of thrill, some notes which he had to complete that morning for his
lecture--and in the same instant he was walking back across the turf
towards his house through the warm May sunshine.

"Yes," he said to himself, as he drew a deep breath of the sweet spring
air. "I was right; that's it. The fourth dimension is a form of duration
in some way correlated with space. I shall have to work that out in the
light of the greater knowledge, which Her vanished Majesty has given me,
and which I almost attained to in Egypt. Wherefore, existence in a state
of four dimensions, or the world of N4, as I have always called it, is,
roughly speaking, one. Time and space are, as it were, two sides of the
same shield, and a person living in that world can see both of them at
once. Wherefore, past, present, future, length, breadth, thickness, here
and there are all the same thing to him. It's a great pity there isn't a
fourth dimensional language as well, so that one could state these
things a little more precisely. But that, of course, is out of the
question.

"Really, I can hardly make myself understand it as far as words and
phrases are concerned; still, there it is; and now the question arises:
Having got this power, as I certainly have, of transferring myself from
one existence to another by a mere effort of thought, because it is very
evident that this power is really only an extension or an
exaltation--confound the language of the third dimension--I can't say
it! Although I understand what it is, it won't go into words. What am I
to do with it? Its possibilities are, of course, a little
appalling--that is to say, from the point of view of N3. I have not the
slightest desire to shake the fabric of Society to pieces, as I could
do, and still less have I taste for spending the rest of my scientific
career in what the world would very easily believe to be conjuring
tricks. I hope I am not going to be another of the unnumbered proofs of
Solomon's wisdom when he said, 'Whoso getteth knowledge, getteth
sorrow.' I wonder what sort of advice Her late Majesty of Egypt----

"Dear me, what nonsense I am talking! Her late Majesty? That won't do at
all--she has reached the Higher
