5? ■ On the Hahits of Ants. 



The nest was divided on the 4th August, 1875, 

 February 11th, 1877. I put in two friends from the other division 

 at 10. I looked at 10.15, 10.30, 11, 11.30, 12, 2, 4, and 

 6, p.m. They were on every occasion quite at home among 

 the others. 

 February 12. Put in three friends at 12. They were also quite at 

 home. I looked at them at 12.30, 1, 2, 4, and 6. Only for 



a minute or two at first one appeared to be threatened. 

 February 13th. Ditto, ditto. The ant was put in at 9.15, a.m., 



and visited at 9.30, 10, 11, 12, and 1. 

 February 15th. Ditto, ditto. The ant was put in at 10.15, a.m., 



and visited at 10.30, 11, 12, 1, 2, 3, and 4. 

 February 19th. Ditto, ditto. The ant was put in at 10, a.m., and 



visited at 10.15, 10.30, 11, 12, 1, and 2. 

 March 11th. Ditto, ditto, at 9.30, a.m., visited at 10.30, 12.30, 



2.30, and 5.30. 

 March 12th. Ditto, ditto, at 10, a.m., visited at 12, 2, and 4. 

 March 18th. Put in two friends at 1, p.m., visited at 2 and 4. 

 April 21st. Put in one friend at 9.30. At 10 she was all right, 



also at 12 and 4. 

 April 22. Put in two friends at 8.30. Visited them at 9, and 10, 



when they were almost cleaned. After that I could not find 



them, but I looked at 2, 4, and 6, and must have seen if they 



were being attacked. 

 April 23rd. Put in two at 12.30. Visited them at 1, 2, 3, 4, and 



6. They were not attacked. 

 May 13th. Put in two friends and a stranger at 7.45 and at 9 the 



two friends were with the rest. The stranger was in a corner 



by herself. 11, ditto. 12, ditto. 1, the friends all right; 



the stranger was being attacked. 2, the friends all right; 



the stranger has been killed and dragged out of the nest. 



The next morningi looked again,the two friends were all right. 

 May 14th. Put in the remaining three friends at 10. Visited them 



at 11, 12, 1, 2, 4, and 6. They were not attacked and seemed 



quite at home. 

 This completed the experiment, which had lasted from August
