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 almost cleaned. At10.30 
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 pupe of 
Formica fusca 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 pupz, 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 4.mM. 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,
