nal, but merely the expiration of
air preparatory to the suctional operation. I have a certain claim to
at least an elementary knowledge of psychology, and in this matter I
am convinced--as firmly as I am convinced of anything--that the
Martians interchanged thoughts without any physical intermediation.
And I have been convinced of this in spite of strong preconceptions.
Before the Martian invasion, as an occasional reader here or there may
remember, I had written with some little vehemence against the
telepathic theory.

The Martians wore no clothing. Their conceptions of ornament and
decorum were necessarily different from ours; and not only were they
evidently much less sensible of changes of temperature than we are,
but changes of pressure do not seem to have affected their health at
all seriously. Yet though they wore no clothing, it was in the other
artificial additions to their bodily resources that their great
superiority over man lay. We men, with our bicycles and road-skates,
our Lilienthal soaring-machines, our guns and sticks and so forth, are
just in the beginning of the evolution that the Martians have worked
out. They have become practically mere brains, wearing different
bodies according to their needs just as men wear suits of clothes and
take a bicycle in a hurry or an umbrella in the wet. And of their
appliances, perhaps nothing is more wonderful to a man than the
curious fact that what is the dominant feature of almost all human
devices in mechanism is absent--the _wheel_ is absent; among all the
things they brought to earth there is no trace or suggestion of their
use of wheels. One would have at least expected it in locomotion. And
in this connection it is curious to remark that even on this earth
Nature has never hit upon the wheel, or has preferred other expedients
to its development. And not only did the Martians either not know of
(which is incredible), or abstain from, the wheel, but in their
apparatus singularly little use is made of the fixed pivot or
relatively fixed pivot, with circular motions thereabout confined
to one plane. Almost all the joints of the machinery present a
complicated system of sliding parts moving over small but beautifully
curved friction bearings. And while upon this matter of detail, it is
remarkable that the long leverages of their machines are in most cases
actuated by a sort of sham musculature of the disks in an elastic
sheath; these disks become pol
