After this, foran hour no more ants came. On this 
occasion, therefore, while there were ten pins, out of 
thirty ants, sixteen came to the right one, while four- 
teen went to one or other of the nine wrong ones. 
July 18.—I put out the boards as before at 4 o’clock. 
Up to 4.25 no ant came. I then put one (No. 1) to the 
honey; she fed for a few minutes, and went away 
at 4.31. 
At 4.35 she came back with four friends, and went 
nearly straight to the honey. At 4.42 she went away, 
but came back almost directly, fed, and went away again. 
At 4.57 she returned, and at 5.8 went away again.
