AFTER LONG SEPARATION. 337 
ants, and almost clean. After 12 a.m.I could not see her 
any more. At 1.40 p.m. I again put into each nest an 
ant from the other, accompanied, however, in both cases 
by a stranger. The contrast was most marked, and no 
one who saw it could have doubted that the friends and 
strangers were respectively recognised as such, or that 
they themselves were fully aware of their posi- 
tion. 
In the first nest the friend at once joined the other 
ants, who began to clean her. The stranger ran about 
in evident alarm, was pursued by the others, and took 
refuge in acorner. At 2 P.M. the friend was with the 
other ants, the stranger alone inacorner. At 2.25 P.M. 
the friend was almost cleaned, and after 2.30 P.M. we 
could no longer distinguish her: the stranger was still 
alone. At 3.40 P.M. she came out of her hiding-place 
and was attacked; after a while she escaped from the 
nest. At 5.30 p.m. she met one of the ants, and a 
battle at once began. I separated the combatants and 
put the stranger back near her own nest, which she at 
once entered, and where she was soon cleaned by her 
own friends. 
I will now describe the adventures of the other 
couple. The friend immediately joined the other ants ; 
the stranger was hunted about and soon seized. At 2 
p.M. the friend was all right, the stranger being dragged 
about. At 2.30 p.m. ditto. The stranger was soon 
afterwards dragged out of the nest. The friend, whom 
I watched at intervals till 6.30 p.m., continued on the 
best. terms with the others; it was quite clear, there- 
fore, that they did not regard her as a stranger. 
She herself was not afraid of, and did not avoid 
them. Still for some time she apparently wished to 
return to the ants with whom she had recently lived. 
She came out of the nest, and tried to find her way 
home. I put her back again, however, and by the even- 
ing she seemed to have accustomed herself to the
