TO THE NEST AFTER COMING TO MATURITY. 137 



as before at 9.15 a.m. At 9.30 they were all right. 

 9.45 ditto. At 10 they were alraost cleaned. At 10.30 

 I could only distinguish one ; and she had only a speck 

 of colour left. She appeared quite at home ; and though 

 I could no longer distinguish the other, I must have 

 seen it if she had been attacked. 



Thus, then, out of seven ants of this batch put back 

 into their old nest, six were amicably received. On the 

 other hand, I put one into nest No. 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 

 was being dragged about. 9 ditto, 9.15 ditto, 9.30 ditto. 

 Evidently therefore she was not treated as a friend. 



Again, on July 14, 1878, I put some pupae of 

 Formica fiisca from nest No. 60 with three ants from 

 nest No. 36. 



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

 emerged from one of these pupse, into her old nest 

 (No. 60). At 4.15 she seemed quite at home. They 

 were already cleaning her ; and by 4.30 she was no longer 

 distinguishable. We watched the nest, however, care- 

 fully for some time ; and I feel sure she was not attacked. 



August 6. — Put another of this batch into nest 

 No. 60 at 7.15 a.m. At 7.30 she was 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 

 ditto ; she was nearly cleaned. 9.30 ditto. 



August 8. — Put in another as before at 7.45. At 

 8 she was all right. 8.30 ditto, 9.30 ditto, 9.45 ditto.
