tinguishable ; of the other two, one was being attacked, the second 

 was taken no notice of, though several ants came up to her. At 

 12.5 the first was dragged out of the nest and then abandoned ; 

 the second was being carefully cleaned. This went on till 12.20, 

 when the paint was entirely removed. 



Sept. 27. I put in three more of these young ants into nest 1, 

 at 7.45 A.M. At 8 o'clock they seemed quite at home among the 

 other ants. A few minutes after, one was being held by a leg ; 

 the other two seemed quite at home. At 8.30 one was almost 

 cleaned, one I could not see. At 9 two of them were quite at 

 home, but I could not see the third. At 9.30 they were both all 

 but cleaned ; and after that we were no longer able to distinguish 

 them. 



Thinking the results might be diflerent if the ants were allowed 

 to become older before being returned into their nests, I made no 

 further observations with these ants for two months. I then took 

 two of the ants which had emerged from the pupse separated on the 

 20th of September, and which had been brought up by ants from 

 nest 2, and on the 22nd of November I put them back at 12 

 in their old nest (that is to say, in nest 1), having marked them 

 as usual, with paint. They showed no signs of fear, but ran 

 about among the other ants with every appearance of being 

 quite at home. At 12.15 do. At 12.30 one was being cleaned. 

 At 12.45 both were being cleaned ; and by 1 o'clock they could 

 scarcely be distinguished from the other ants. There had not 

 been the slightest symptom of hostility. After this hour we 

 could no longer identify them ; but the nest was carefully watched 

 throughout the afternoon, and I think I can undertake to say 

 that they were not attacked. "When we left off watching, the 

 nest was enclosed in a box. The next morning I examined it 

 carefully to see if there were any dead bodies. This was not the 

 case ; and I am satisfied, therefore, that neither of these two ants 

 was killed. To test these ants, I then, on the 24th of November, 

 at 8.80 A.M., put into the nest two ants from nest 2. At 8.40 

 one was attacked ; the other had hid herself away in a corner. 

 At 9.15 both of the ants were being dragged about. At 9.85 one 

 was dragged out of the nest and then released, and the other a 

 few minutes afterwards. After watching them for some time to 

 see that they remained outside, I restored them to their own 

 nest. The contrast, therefore, was very marked. 



Again, on Nov. 25, I took two ants which had emerged from
