336 RECOGNITION OF FRIENDS 
A.M, ditto, 10 a.m. ditto, 10.30 a.M. ditto. Others had 
almost entirely cleaned off the paint. 
At 5 P.M. put a friend and a stranger into the other 
half of the nest. At 5.15 a.m. the friend seemed 
quite at home, and had been nearly cleaned; the 
stranger was being attacked. 5.30 a.m. ditto, 8.15 a.m. 
ditto. 7.15 a.m. Two of the ants were dragging the 
stranger out of the nest; the friend had been quite 
cleaned. 
August 14.—At 8.15 a.m. I put an ant from each 
half of the nest into the other. At 8.30 a.m. one was 
alone in the corner, the other was being attacked. At 
9 A.M. both were being attacked. 9.30 .m. ditto, 10.30 
A.M. ditto; 11.30 a.m. ditto, both, however, being almost 
cleaned. 
August 19.—At 8 a.m.I put into each nest one 
from the other. The one was received amicably and 
cleaned, so that after a while I lost sight of her. It was

into the same nest another friend: at 11.30 a.m. she. 
was all right, and, being cleaned at 12 a.m., I could no 
longer distinguish her. 
The ant put into the other nest was not so well 
received. At 9.30 4.M., 11.30 a.M., and 12.30 a.m. she 
was being dragged about, but she was also being cleaned, 
and after 12.30 a.m. I lost sight of her. As the paint. 
had been entirely removed, but no ant was being 
attacked, I have no doubt she was at length recognised 
as a friend. 
August 21.—At 10.15 4.M. I again put into each 
nest an ant from the other. One was at once cleaned, 
and I could not find her. I should, however, certainly 
have seen her if she had been attacked. 
The other was at first attacked by one of the ants; 
but this soon ceased, and they began to clean her. By 
11.30 a.M. she was quite at her ease among the other
