abbit was more intelligent than the
cat, the fox, the dog, and even than the horse.

In the same work the following figures express the average size of the
brain in different races of men.

Pariahs of India 1332 cubic centimetres.
Australians 1338 "
Polynesians 1500 "
Ancient Egyptians 1500 "
Merovingians 1537 "
Modern Parisians 1559 "

This would prove that the people who built Karnac and the Pyramids,
who raised to an elevation of about 500 feet blocks of granite, one of
which would require fifteen horses to drag it along a level road, who
placed these enormous stones side by side without mortar or cement of
any kind and with almost invisible joints, who possessed the secret of
malleable glass and of painting in colours that have not faded even
after the lapse of centuries ... that such a race of men were inferior
to the rude, uncultured Merovingians, and scarcely the equals of the
Polynesians!

Science also tells us that in a child five years of age the human
brain weighs, on an average, 1250 grammes--this, too, would bear no
relation whatever with the intellectual and moral development of a
child of that age and that of an adult man.

Though Cuvier's brain weighed 1830 grammes, and Cromwell's 2230, that
of Tiedemann, the great anatomist, when placed on the scales, weighed
no more than 1254, and that of Gambetta only 1246.

The physical body of itself can give no reason for a host of
psychological phenomena on which, however, a flood of light is shed if
one recognises the existence of other vehicles of consciousness
possessing more far-reaching vibrations, and consequently capable of
expressing higher faculties. During sleep, for instance, which is
characterised by the Ego having left his physical body, reason is
absent, and what we call dreams are generally nothing but a tissue of
nonsense, at which the dreamer feels astonishment only when returning
to his body on awaking. On the other hand, as we have seen in Chapter
I., when the Ego succeeds in imprinting on the brain the vibrations of
the higher consciousness, it is able to regain the memory of facts
long forgotten and to solve problems that could not be solved during
the waking state. There are madmen who have ceased to be mad during
somnambulism; persons of rudimentary intelligence have proved
themselves to be profound thinkers during the mesmeric trance; when
under som
