ROTATING TABLE. 265 



rurbed them ; but they very soon re-established the 

 chain. 



2. I turned round the central piece of the table G 

 F, so that the paper G F was reversed, o being where 

 F had been, and vice versa. This did not seem to 

 diconcert the ants at all. They went straight over 

 the paper as before, without a moment's hesitation. 



3. When some ants were between i and D, 1 rotated 

 the outer circle of the table halfway round, which of 

 course carried the cup containing the larvae from L to B. 

 The ants took no notice of this, but went straight to L. 



4. When some ants were between 1 and D, I rotated 

 the table several times, bringing it finally to its 

 original position. This disturbed them a good deal ; 

 but eventually they all continued their course to L. 



5. When some ants were between I and D, I half 

 rotated the two centre parts of the table, the result of 

 which, of course, was that the ant was moving to- 

 wards, instead of away from, the nest. In every case 

 the ants turned round too, oo as duly to reach L. So 

 also those which were on their way back from the 

 larva? to the nest turned in the same manner. 



6. When the ants were between I and D, I half 

 rotated the whole table. Again the ants turned round 

 too, though of course in this case, when they reached 

 the place where L had been, the cup with the larva? 

 waa behind them at R. 



The two latter experiments, though quite in accord- 

 with those previously made, puzzled me a good
