She buzzed about at the other window for a few 

 minutes, which made the interval longer than 

 usual.

It will be seen that the intervals of her absence 

 were remarkably regular. On one occasion, indeed, 

 she was only away four minutes ; but this time I think 

 she had been disturbed, and had not provided herself 

 with a regular supply of food. 



The number of visits was fifty-one in eleven hours 

 and a half. I tried whether she would be in any way 

 afifected by a dead wasp, so I put one on the honey ; 

 but she took no notice whatever. 



I observed with other wasps, that when the open 

 window was not the shortest way to their nests, they 

 had a great tendency to fly to that which was in the 

 right direction, and to remain buzzing about there.
