contrary, which I put in with her, got out at once. At 
11.30 I put another bee and a fly into the same glass: 
the latter flew out at once. For half an hour the bee 
tried to get out at the closed end; I then turned the 
glass with its open end to the light, when she flew out at

more with the same result. 
Some bees, however, have seemed to me more in- 
telligent in this respect than others. A bee which I 
had fed several times, and which had flown about in

which opened from my hive directly into my room,

window. 
One day (April 14, 1872), when a number of 
them were very busy on some berberries, I put a saucer 
with some honey between two bunches of flowers ; these 
flowers were repeatedly visited, and were so close that 
there was hardly room for the saucer between them,

bunches of flowers, and it was eagerly sucked by the 
bees ; two kept continually returning till past five in 
the evening. 
One day when I came home in the afternoon I found 
that at least a hundred bees had got into my room 
through the postern and were on the window, yet not
