found their way to them by tracking a’s footsteps. If the 
former, they would in any case pass over the bridge K

then as the piece of paper by which A passed was 
transferred to L, it would mislead them and carry them 
away from the larve to1. In every case, then, I trans-

soon as the ant A had crossed over K and L. 
I put her (November 7, 1875) to the larve on F 
at 6.15 am. After examining them carefully, she re- 
turned to the nest at 6.34. No other ants were out ; 
but she at once reappeared with four friends and 
reached the larve at 6.38. None of her friends, how- 
ever, crossed the bridge; they went on to D, wandered 
about, and returned home. a returned to the larvee at 
6.47, this time with one friend, who also went on to D 
and returned without finding the larve.
