cell with au equal uumber of unsmeared B-h ?lwU. In no ease 

 did the unsmeared ants attack the ants that had been merged in the 

 juices of their kin; but the smeared ants attacked the unsmeared 

 ants as they commonly attacked aliens. The smeared ants never 

 attacked each other. 



After a worker had been smeared in the juices of ants of an 

 alien colony and then isolated for about thirty hours it was 

 returned to its colony, and every worker that touched it with the 

 antennaj started back in alarm, but it was not attacked nor 

 harmed. The juices probably wore off gradually, since smeared 

 workers returned to their colony after one week of isolation were 

 received with no sign of distrust. 



A queen that had for over three months peacefully shared the 

 cell and labors of a sister-queen and five workers was smeared with 

 the juices of aliens and at once returned to the cell. She was 

 immediately attacked by the workers as if she were an alien. 

 She evinced dread and submission in the usual manner of these 

 ants by cowering low, tightly shutting her mandibles, folding her 

 antenure and holding them close down upon her head. Three 

 Avorkers together attacked her, but the attacks were intermittent, 

 and she soon crept up to her sister-queen. The queen prodded he 

 curiously with the ends of the antenuit and showed no animosity. 

 Then a worker came and nabbed her in places and licked her in 

 places, as though she was a composite of alien and kin. She was 

 kept aloof from the group for a day or two and then resumed 

 without harm her former associations. 



Workers merged in alien juices were likewise attacked on being 

 restored to their kiu, but the attacks were not persistent and 

 none were slain. The losses of life or limbs all occurred through 

 the attacks of the smeared workers upon the aliens, among whom 

 they were as wolves in sheep's clothing. The smeared ants, in 

 spite of their disguise, must have retained some evidences of their 

 lineage which protected them from extreme violence. 



When two parties, each consisting of several workers that had 

 been merged in the juices of the kiu of the other party, were 

 placed together in a new Petri cell, there were no violent attacks 

 from either side during the first two or three days. A tendency to 

 congregate according to colony showed itself from the beginning, 

 but by keeping the cell clean and preventing separate settlement of
