A long tubular sea-anemone, with a fine crown of tentacles around the
mouth. The suggestion of a flower is very obvious. By means of stinging
lassoes on the tentacles minute animals on which it feeds are paralysed
and captured for food.]
[Illustration: THIS DRAWING SHOWS THE EVOLUTION OF THE BRAIN FROM FISH
TO MAN
The Cerebrum, the seat of intelligence, increases in proportion to the
other parts. In mammals it becomes more and more convoluted. The brain,
which lies in one plane in fishes, becomes gradually curved on itself.
In birds it is more curved than the drawing shows.]
