from one of my nests (No. 36) with two workers from another 

 nest of the same species. Two emerged from the chrysalis-state 

 on the 30th ; and on the 2nd September I put them, marked as 

 usual, into their old nest (No. 36) at 9.30 a.m. At9.45 they seemed 

 quite at home, and had already been nearly cleaned. At 10'15 

 the same was the ease, and they were scarcely distinguishable. 

 After that I could no longer make them out ; but we watched the 

 nest closely, and I think I can undertake to say that if they had 

 been attacked we must have seen it. 



Another one of the same batch emerged on the 18th August, 

 but was rather crippled in doing so. On the 21st I put her into 

 the nest (No. 36). This ant was at once attacked, dragged 

 out of the nest, and dropped into the surrounding moat of water. 



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

 Formica fusca from No. 36 into a glass with three ants of the 

 same species from nest No. 60. 



On the 22nd I put an ant which had emerged from one of these 

 pupse into her old nest (No. 36) at 9.30 a.m. She was at once 

 attacked. 10, she is being dragged about. 10.30 do. 



Aug. 8. Put another ant which had emerged from one of these 

 pupsB into her old nest (No. 36) at 7.45 a.m. At 8 she seemed 

 quite at home among the others. 8.15 do., 8.30 do., 9 do. 9.30 do. 



Aug. 9. Put two other young ants of this batch into their old 

 nest (No. 36) at 7 a.m. At 7.30 they were all right. At 7.30 

 one of them was being dragged by a leg, but only, I think, to 

 brirfg her under shelter, and was then let go. Young ants of this 

 species, when the nest is disturbed, are sometimes dragged to a 

 place of safety in this way. At 8.30 they were all right and 

 nearly cleaned. After this I could not distinguish them ; but if 

 they had been attacked, we must have seen it. 



Aug. 11. Put in another one as before at 8.30 a.m. At 8'45 

 she was all right. At 9 she was dragged by a leg, like the last, 

 but not for long ; and at 9.30 she was quite comfortable amongst 

 the others. 10 do., 10.45 do., 12 do., 5 do. 



Aug. 24. Put in the last two ants of this lot as before at 

 9.15 a.m. At 9.30 they were all right. 9.45 do. At 10 they 

 were almost 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
