ROTATING TABLE. 265 
turbed them; but they very soon re-established the 
chain, 
2. I turned round the central piece of the table @ 
F, so that the paper G F was reversed, G being where 
¥ had been, and vice versd. 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,I rotated 
the outer circle of the table halfway round, which of 
course carried the cup containing the larvee from L to B. 
The ants took no notice of this, but went straight to L. 
4, When some ants were between I and p, 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, so as duly to reach L. So 
also those which were on their way back from the 
larvee to the nest turned in the same manner. 
6. When the ants were between I and p,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 larve 
was behind them at B. 
The two latter experiments, though quite in accord- 
ance with those previously made, puzzled me a good
