224 SIE JOHN LUBBOCK ON THE HABITS OF ANTS. 



four friends were still lying as before, Avliile the four strangers 

 had been removed. Two of them I found had been thrown over 

 the edge of the board on which the honej was placed. The other 

 two I could not see. 



Again, on the 14th Sept., at 8.40, 1 put in the same way four 

 friends marked white, and four strangers marked red, close to 

 where my L.flavus were out feeding on honey placed on a slip 

 of glass over water. For some hours they took no notice of 

 them. At length one took a friend, and after carrying her about 

 some time, at 12.40, dropped her into the water. Some time 

 after another took up a stranger and carried her into the 

 nest at 2.35. A second stranger was similarly carried into the 

 nest at 2.55, a third at 3.45, while the fourth was thrown over 

 the edge of the board at 4.20. Shortly after this two of the 

 strangers were brought out of the nest again and thrown away. 

 A second friend was thrown away, like the first, at 4.58, the third 

 at 5.17, and the fourth at 5.46. I could not ascertain what hap- 

 pened to the last stranger, but have little doubt that she was 

 brought out of the nest and thrown away like the rest. 



On the following day at 6.45 I tried the same experiment 

 again, only marking the friends red and the strangers white. At 

 7 one of the strangers was carried off and dropped over the edge 

 of the glass into the water, and at 8 a second. At 8.45 a friend 

 was taken up and, after being carried about some time, was thrown 

 into the moat. At 9.45 a friend was picked up and carried into 

 the nest, but brought out again and thrown away about 3 in the 

 afternoon. The other four remained where they were placed 

 until 8 P.M., and though the other ants often came up and exa- 

 mined them, they did not carry them off. 



Sept. 29. Again placed nine chloroformed ants, five friends 

 and four strangers, close to where a number were feeding. There 

 was a continual stream of ants to the honey, ten or fifteen being 

 generally there at once. 



A stranger was picked up at 10.20 and dropped at 10.32 



10.22 „ 10.35 



A friend „ „ 11.22 „ 11.42 



A stranger „ „ 11.35 „ 11.50 



11.41 „ 11.45 



Shortly after the others were picked up and carried away to 

 the edge of the board, where they were dropped, but none were 

 taken into the nest.
