which they are now living.

It is also claimed that, when their earth cools and the frigid blasts
freeze out the world, there will gradually commence the Age of Ice, or
the age in which human species will exist by reason of the earth's stiff
coldness.

I had no way of learning the truth or falsity of this theory.


THOUGHT PHOTOGRAPHY.

These Ploidites have distanced us in the study of the nervous system,
including the intricate problems of the cerebrum and cerebellum. They
have ascertained, by long ages of observation and experimenting, the
exact effect of every kind of impulse on the brain matter. The experts
are able to tell, at a post-mortem examination, what kinds of thinking
were most prevalent during the subject's life, just as easily as we can
judge the great or little use of the arm by an examination of its
muscles.

But more wonderful, a thousand fold, is their ability to follow the
course of thought in a living cerebrum after the brain has been made
visible by a light more potent than the X ray. After this exposure the
operator, with his wizard magnifying lens, watches the tiny tremulous
brain cells in their infinitesimal quivering, as they carry messages
from the soul to the world of sense and being.

The voluntary nerve action is distinguished from the involuntary, and
there is no escape from the conclusions formed by an expert observer.
