an ant, and even, on two occasions, to bring out
the cells and filaments of the cortex. Here in the brain of an ant, is
an anatomical and physiological similarity to the brain of man:
therefore, it is reasonable to expect evidences of mental operations in
the ant akin to those of man.

That we do find these evidences in abundance can no longer be denied.
Sir John Lubbock chloroformed some _Lasius niger_ belonging to his
formicary. The other ants brought their anaesthetized comrades out of the
nest and carried them away; they thought that they were dead. He made
some other specimens of the same species intoxicated, and the ants
carefully bore their helpless companions back into the nest. The care
evinced in helping their intoxicated friends to reach the safe shelter
of their nest undoubtedly indicates a sense of sympathy toward the
afflicted individuals.

Ants frequently display sympathy for mutilated companions. Whether or
not this feeling is ethical or material is not and can not be
determined; the fact remains, however, that sympathy is evinced. I
myself have observed it on many occasions. I removed the anterior pair
of legs from a specimen of _Lasius flavus_, and placed her near the
entrance to her nest. In a short time a companion came to her
assistance, and, lifting her with her mandibles, carried her into the
nest. A specimen of _F. fusca_, destitute of antennae, was attacked and
severely injured by an ant of another species. An ant of her own species
soon came by. "She examined," says Lubbock, whom I quote, "the poor
sufferer carefully, then picked her up tenderly and carried her into the
nest. It would have been difficult for any one who witnessed the scene
to have denied to this ant the possession of human feelings."[52]

Not only do they display sympathy toward mutilated and helpless friends,
but also toward healthy individuals who may accidentally get into
trouble and need assistance. Belt, while watching a column of _Eciton
hamata_, placed a stone upon one of them to secure her. The next ant in
line, as soon as she discovered the condition of her friend, ran
hurriedly backward and communicated the intelligence to the others.
"They rushed to the rescue; some bit at the stone and tried to move it,
others seized the prisoner by the legs and tugged with such force that I
thought the legs would be pulled off; but they persevered until they got
the captive fre
