616 SIR JOHN lubboce: on ants, bees, and wasps. 



old nest, six were amicably received. On tlie other hand, I put 

 one into nest JSTo. 60, from which the three nurses were taken. 

 She was introduced into the nest at 8.15 a.m., and was at once 

 attacked. 8.45, she is being dragged about. 9, do. ; 9.15, do. ; 

 9.30, do. Evidently therefore she was not treated as a friend. 



Again, on the 14th July last year (1878) put some pupae of 

 Formica fusca from nest No. 60 with three ants from nest No. 36. 



On the 5th August at 4 p.m. I put an ant which had emerged 

 from one of these pupae, into her old nest (No. 60). At 5.15 she 

 seemed all right. They were already cleaning her ; and by 4.80 

 she was no longer distinguishable. AVe watched the nest, 

 however, carefully for some time ; and I feel sure she was not 

 attacked. 



Aug. 6. Put another of this batch into nest No. 60 at 7.15 a.m. 

 At 7.30 she is not attacked. At 8, one of the ants was carefully 

 cleaning her. At 8.15 she was quite at home among the others. 

 At 8.30 do., she was nearly cleaned. 9.30 do. 



Aug. 8. Put in another as before at 7.45. At 8 she is all 

 right. 8.30 do., 9.30 do., 9.45 do. 



Aug. 9. Put in another as before at 7 a.m. At 7.30 she is 

 quite at home among the others, and already nearly cleaned. At 

 8 I could no longer distinguish her ; but certainly no ant was 

 being attacked. 9 do. 



Aug. 11. Put in another as before at 8 a.m. At 8.15 she is 

 quite at home. 8.30 do., 9 do., 9.30 do., 10 do., 12.30 do. 



Aug. 13. Lastly, I put in the remaining young ant as before 

 at 7 A.M. At 7.15 she was all right. At 7.30 do. and nearly 

 cleaned. At 8 I could no longer distinguish her ; but no ant was 

 being attacked. 



Thus, then, as in the preceding experiment, these six ants when 

 reintroduced into the nest from which they had been taken as 

 pupae, were received as friends. On the other hand, on the 5th 

 August I put a young ant of the same batch into nest No. 36, 

 from which the three nurses had been taken. She was introduced 

 at 11 and was at once attacked. At 11.30 she was being dragged 

 about, and shortly after was put to death. I then introduced a 

 second ; but she was at once attacked like the first. 



Aug. 22. I put some pupse of Formica fusca from nest No. 64 

 under the charge of three ants from No. 60. By the 7th Septem- 

 ber several young ones had emerged. I put two of them into nest 

 No. 64 at 8.15 a.m. They were amicably received, as in the pre-
