Ants. 



Becollection of Friends. 

 In my last paper I recorded some experiments made on a nest oi 

 Formica fusca which I had divided into two parts. I found that 

 while a stranger introduced into the nest was attacked, driven 

 out, or even killed ; and while strangers so introduced showed 

 every sign of fear and an unmistakable desire to escape, friends, 

 on the other hand, put back among their old companions, even 

 after months of separation, were amicably received, and made 

 themselves quite at home. Since my last paper I have continued 

 the observations, as follows : — 



The nest was divided on the 4th Aug. 1875. 



iPeb. 11, 1877. I put in two friends from the other division at 

 10 A.M. 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 amongst the others. 



Feb. 12. Put in three from the other division at 12. They 

 were 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. 



Feb. 13. Put in one friend from the other division. The ant 

 was put in at 9.15 a.m., and visited at 9.30, 10, 11, 12, and 1. 



Feb. 15. Do. The ant was put in at 10.15 a.m., and visited 

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



Feb. 19. Do. The ant was put in at 10 a.m., and visited at 

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