SIR JOHN IVBBOCK ON THE HABITS OP ANTS. 231 



there might be no question whether perhaps the difference of 

 treatment was due to the difference of colouring. At 11 a.m. the 

 friend was all right, the stranger was being dragged about by an 

 antenna. 11.30 a.m. the friend all right, the stranger being dragged 

 about by one leg. 12 do. 12.30 p.m. the friend all right, the 

 stranger being dragged about by an antenna. 1 p.m. do., 2 p.m. 

 do., 3 P.M. do. 



3rd July. Put in a friend and a stranger at 11 a.m. At 11.30 

 A.M. the stranger was being dragged about, the friend was being 

 cleaned. 12 do. 12.30 a.m. both were now being attacked. 1 do. 



This seems to show that some, at least, of the ants have for- 

 gotten their old friends. 



16th July. Put in two friends at 7.45 a.m. At 8 a.m. each was 

 being dragged about by an antenna. 8.30 a.m. one was being 

 dragged about by both antennae, the other by both antennae and 

 one leg. 10 a.m. both were still attacked, but it is curious that 

 at the same time others were cleaning off the paint. 12.30, both 

 still attacked. 



17th July. Put in a friend at 8.15 a.m. At 8.30 they were 

 cleaning her. At 9 a.m. she was almost clean. 9.30 she seemed 

 quite at home, and had only one spot of paint on her. 10.20 do. 



20th July. Put in a friend and stranger at 9 a.m. At 9.30 a.m. 

 the friend seemed all right ; the stranger was in a corner by her- 

 self. At 10 A.M. the friend was being cleaned ; the stranger had 

 come out of her corner and was being fiercely attacked. At 11 

 A.M. the friend seemed quite at home and was almost cleaned ; the 

 stranger was being dragged about, but was almost cleaned. At 

 12 the same thing was going on, and also at 12.30. At 1 .30 the 

 stranger was still being pulled about ; but what struck me as re- 

 markable, the friend also had hold of one of the ants by an antenna. 

 At 2 P.M. the friend was by herself, the stranger was being at- 

 tacked. At 4 P.M. the friend again had hold of an ant by an 

 antenna ; the stranger was being pulled about. At 5 the friend 

 seemed quite at home in the nest ; the stranger was killed. The 

 following morning I was still able to distinguish the friend ; she 

 seemed quite at home. 



6th Aug. Put in a stranger and a friend at 8 a.m. At 8.30 both 

 were attacked. 9 do., 9.30 do., 10 do., 11 do., 12.30 do. 



6th Aug. Eepeated the experiment at 2. Both ants hid them- 

 selves in corners. At 3.30 the stranger was being attacked ; the 

 friend was in a corner by herself At 4.30 both were attacked. 

 5.30 do.
