150 RECOGNITION NOT INDIVIDUAL OR PERSONAL, 
each half of the nest. I will call the two halves as 
before A and B. 
On August 15, at 9 a.M., I put three of the young 
ants from A into B, and three from Binto A. At 
9.30 A.M. none were attacked, 10 a.m. ditto, 10.30 4.M. 
ditto. One was being cleaned; 12 a.m. ditto, 2 P.M. 
ditto. In fact, they seemed quite at home with the 
other ants. The next morning I was unable to recog- 
nise them, the paint having been entirely removed. 
The ants were all peaceably together in the nest, and 
there were no dead ones either in the nest or in the 
outer box. It is evident, therefore, that they had 
been treated as friends. 
August 17.—I put in three more from B into A at 
noon. At 12.30 p.m. they were with the other ants; 
at 1 p.M., ditto, at 2 P.M. ditto, at 3 P.M. ditto, at 
5 pM. ditto. The following morning I was still able 
to recognise them, though most of the paint had been 
removed. They also were evidently treated as part of 
the community. 
September 19.—Put in three more from A into B 
at 8.30 4.M. I looked at them at intervals of half an 
hour, but none of them were attacked. Next morning 
‘there was no ant outside the nest, nor had any been 
killed. 
October 10.—Put in three more at 7 a.M., and 
looked at intervals of an hour. They were not at- 
tacked, and evidently felt themselves among friends. 
The next morning I was still able to recognise two.
