e more than the tenth part of an inch; and in a
Polygon of six or seven hundred sides the sides are little larger than
the diameter of a Spaceland pin-head. It is always assumed, by
courtesy, that the Chief Circle for the time being has ten thousand
sides.

The ascent of the posterity of the Circles in the social scale is not
restricted, as it is among the lower Regular classes, by the Law of
Nature which limits the increase of sides to one in each generation.
If it were so, the number of sides in a Circle would be a mere question
of pedigree and arithmetic, and the four hundred and ninety-seventh
descendant of an Equilateral Triangle would necessarily be a Polygon
with five hundred sides. But this is not the case. Nature's Law
prescribes two antagonistic decrees affecting Circular propagation;
first, that as the race climbs higher in the scale of development, so
development shall proceed at an accelerated pace; second, that in the
same proportion, the race shall become less fertile. Consequently in
the home of a Polygon of four or five hundred sides it is rare to find
a son; more than one is never seen. On the other hand the son of a
five-hundred-sided Polygon has been known to possess five hundred and
fifty, or even six hundred sides.

Art also steps in to help the process of the higher Evolution. Our
physicians have discovered that the small and tender sides of an infant
Polygon of the higher class can be fractured, and his whole frame
re-set, with such exactness that a Polygon of two or three hundred
sides sometimes--by no means always, for the process is attended with
serious risk--but sometimes overleaps two or three hundred generations,
and as it were doubles at a stroke, the number of his progenitors and
the nobility of his descent.

Many a promising child is sacrificed in this way. Scarcely one out of
ten survives. Yet so strong is the parental ambition among those
Polygons who are, as it were, on the fringe of the Circular class, that
it is very rare to find a Nobleman of that position in society, who has
neglected to place his first-born in the Circular Neo-Therapeutic
Gymnasium before he has attained the age of a month.

One year determines success or failure. At the end of that time the
child has, in all probability, added one more to the tombstones that
crowd the Neo-Therapeutic Cemetery; but on rare occasions a glad
procession bears back the little one to his exultant parents, no longer
a Po
