336 EECOGNITION 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 a.m. ditto, 10.30 

 A.M. ditto ; 1 1.30 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 

 clear that she was received in a friendly manner, 

 because no fighting was going on. At 11 a.m. I put 

 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 a.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 a.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 

 1 1 .30 a.m. she was quite at her ease among the other
