BEHAVIOUR TO CHLOROFORMED FRIENDS. 109 



their insensible fellow creatures. At 9.20 I found that 

 four friends were still lying as before, while the four 

 strangers had been removed. Two of them I found 

 had been thrown over the edge of the board on which 

 the honey was placed. The other two I could not see. 



Again, on September 14, at 8.40, I put in the 

 same way four friends marked white, and four" 

 strangers marked red, close to where my L. Jlavus were 

 out feeding on honey placed on a slip of glass over

 about some time dropped her, at 12.40, into the water. 

 Some time after another took up a stranger and carried 

 her into the nest at 2.35. A second stranger was 

 similarly carried into the nest at 2.55, a third at 3.45, 

 while the fourth was thrown over the edge of the board 

 at 4.20. Shortly after this two of the strangers were

 water. A second friend was thrown away, like the 

 first, at 4.58, the third at 5.17, and the fourth at 5.46.

 but have little doubt that she was brought out of the 

 nest and thrown away like the rest.

 were distinguished. At 7 one of the strangers was carried 

 off and dropped over the edge of the glass into the water, 

 and at 8 a second. At 8.45 a friend was taken up and; 

 after being carried about some time, was thrown into
