[April 1887. 
We now repeated the experiment with the same conditions 
excepting that the bones were cold, and that the wasps seemed 
to be unusually busy as they were working very rapidly. 
In nine minutes nine wasps noticed the bundle containing the 
bones, circling around it once or twice, but only two alighted. 
The empty bundle was noticed by one wasp. 
Two day s after this experiment we used the bones once more. 
They were now cold and dry and gave ofF little if anv odor. In 
five minutes of 129 wasps which entered the nest tw'o settled on. 
and walked over the gauze containing the bones. None visited 
tne empty bundle.
