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.

and at 8asecond. At 8.45 a friend was taken up and, 
after being carried about some time, was thrown into
