“ Mrs. Elizabeth Agassiz relates that a gentleman of her acquaint 
ance removed the attached bunch of eggs from a star-fish in his 
aquarium, for examination, and afterwards put them back again. To 
his surprise, the star-fish at once crawled toward them and gathered 
them again into a cluster under her. Curious to test how far this 
apparently maternal solicitude was a reality, he again took away the 
eggs and put them in a distant part of the aquarium. A second time 
the animal spread herself over them. Once more removing the eggs 
to the opposite end of the tank, he set a piece of stone in front 
of them. The distressed mother immediately began to search for 
her lost treasures, and w-hen, after circling the obstacle, she seemed 
to catch sight of them, she made straight for the eggs and a third 
time enwrapped them in her embrace. This incident is remarkable 
not only for the strong maternal attachment displayed, but also for 
the sharpness of eyesight it implies.”—(Scribner's Magazine, vol. xxii., 
ft- 652.) 
The intelligence of the snail seems to be duly indicated 
in the following experiment:— 
“ Mr. W. White fixed a land-shell, mouth uppermost, in a chink of 
rock. In a short time the snail protruded itself to its utmost length, 
and attaching its foot vertically above, tried to pull the shell out in a 
straight line. Not succeeding, it rested for a few minutes, and then 
stretched out its body on the right side and pulled its utmost, but 
failed. Resting again, it protruded its foot on the left side, pulled 
with its full force, and freed the shell. This exertion of force in 
three directions, which seems so geometrically suitable, must have 
been intentional.”-—(Romanes. Animal Intelligence, ft. 26.) 
The centipede is armed with eight eyes and seventeen- 
jointed antennae; it is the quick and ruthless hunter 
of insects, pursuing them to their lurking-places and 
giving them no quarter. On what ground should we 
deny the possession of intelligence to this insect of prey 
which we should readily allow to a beast of prey, if he 
conducted himself in a similar manner ? 
Again, the line is drawn between intelligent and non- 
intelligent animals, because it is taken for granted that 
intelligence cannot exist before a particular stage of 
organic development has been reached. I will take an
