10.26 she went and examined cup 2, then to cup 3 



and took a larva. 

 At 10.45 she came to cup 3, and I went to bed. 

 At 7 o'clock the next morning the larvae were all 

 removed. In watching this ant I was much struck by 

 the difficulty she seemed to experience in finding her 

 way. She wandered about at times most irresolutely, 

 and, instead of coming straight across from the door of 

 the frame to the cups, kept along the side of the box ; 

 so that in coming to cup 3 she went twice as far as she 

 need have done. Again, it is remarkable that she should 

 have kept on visiting the empty cups time after time. 

 I watched for this ant carefully on the following day ; 

 but she did not come out at all. 



During the time she was under observation, from 1 

 till 10.45, though there were always ants roaming about, 

 few climbed up the walls of the cup. Five found their 

 way into the (empty) cup 1, and one only to cup 3. It 

 is clear, therefore, that the ant under observation did 

 not communicate her discovery of larvse to her friends. 

 In the afternoon of the following day I watched the 

 ant which had been under observation on the 3rd Jan. 

 From 3.27 to 9.30 she made forty-two visits, during 

 which time only four other ants came to the larvse. 



On January 10 I watched the same ant as on the 

 4th. Between 11 a.m. and 10 p.m. she made no less 

 than ninety- two visits ; and during the whole time only 

 one strange ant came to the larvae. 



On January 18 I put out some more larvae in the 

 small porcelain cups. Between 8 and 9 both these ants 

 found them, and kept on coming all day up to 7 p.m., 

 when I left off observing. There were a good many 

 ants wandering about in the box; but up to 4 o'clock 

 only four came to the larvae. Two of them I impri- 

 soned as usual; but two (which came at 4.30 and 4.36)
