After which I went on watching till 7, but none of 
these three returned. During the day 7 ants came to 
this honey, and 27 to the other four deposits. Here,

not communicate, at any rate, any exact information to 
their friends. 
June 27, 1875.—I placed four inverted glasses 
(tumblers) on the grass, and on the top of each placed 
a little honey. I then, at 8 o’clock, put two ants, be- 
longing tc F’. nigra, to the honey on one of the glasses. 
At 8.25 No. 1 came back, and at 8.45 she returned 
to the nest, but did not come to the honey any more. 
At 9.5 No. 2 came out and wandered about ; I put 
her to the honey again; she fed and at 9.22 returned

August 7, 1875.—I put out four small deposits of 
honey (which I continually renewed) on slips of glass 
placed on square pieces of wood, and put an ant (Z. 
niger) to one of them at 9.20. She fed and went away.
