did so with much more hesitation and lesstimmediately.

experiment, but without the box. The results were as

From these last two experiments it is obvious that 
the presence of the box greatly affected the result, and 
yet the previous results made it difficult to suppose 
that the ants noticed any objects so distant as the walls 
of the rooms, or even as I was myself. The result 
surprised me considerably ; but I think the explanation 
is given by the following experiments. 
Tagain put some larve in a cup, which I placed in 
the centre of the table; and I let out an ant which I 
had imprisoned after the previous experiments, placing 
her in the cup; she carried off a larva to the nest and

rotated the table: when she came out she seemed a
