em to suck all
life and vigour from the rest of his frame. His limbs shrivel, his heart
and digestive organs diminish, his insect face is hidden under its bulging
contours. His voice becomes a mere stridulation for the stating of
formula; he seems deaf to all but properly enunciated problems. The
faculty of laughter, save for the sudden discovery of some paradox, is
lost to him; his deepest emotion is the evolution of a novel computation.
And so he attains his end.

"Or, again, a Selenite appointed to be a minder of mooncalves is from his
earliest years induced to think and live mooncalf, to find his pleasure in
mooncalf lore, his exercise in their tending and pursuit. He is trained to
become wiry and active, his eye is indurated to the tight wrappings, the
angular contours that constitute a 'smart mooncalfishness.' He takes at
last no interest in the deeper part of the moon; he regards all Selenites
not equally versed in mooncalves with indifference, derision, or

accomplished mooncalf technique. So also he loves his work, and discharges
in perfect happiness the duty that justifies his being. And so it is with
all sorts and conditions of Selenites--each is a perfect unit in a world
machine....

"These beings with big heads, on whom the intellectual labours fall, form
a sort of aristocracy in this strange society, and at the head of them,
quintessential of the moon, is that marvellous gigantic ganglion the Grand
Lunar, into whose presence I am finally to come. The unlimited development
of the minds of the intellectual class is rendered possible by the absence
of any bony skull in the lunar anatomy, that strange box of bone that
clamps about the developing brain of man, imperiously insisting 'thus far
and no farther' to all his possibilities. They fall into three main
classes differing greatly in influence and respect. There are
administrators, of whom Phi-oo is one, Selenites of considerable
initiative and versatility, responsible each for a certain cubic content
of the moon's bulk; the experts like the football-headed thinker, who are
trained to perform certain special operations; and the erudite, who are
the repositories of all knowledge. To the latter class belongs Tsi-puff,
the first lunar professor of terrestrial languages. With regard to these
latter, it is a curious little thing to note that the unlimited growth of
the lunar brain has rendered u
