April 19. I put out a little syrup on eleven slips of 

 glass,which I placed on eleven inverted flower pots on the 

 lawn. At 8.35 a Lasius niger found the honey on one 

 of the flower-pots. 



After which I watched till 6 P.M. ; but she did not 

 return again to the honey. During the above time 

 eight ants came to the same honey, and twenty-one to 

 the other ten deposits. 



On July 111 put one of my specimens of Lasius 

 niger to some honey at 7.10. She fed till 7.25, when 

 she returned to the nest. 



At 7.32 she returned. At 7.36 another ant came, 



7.47 7.50 [whom I imprisoned.
