The Hunting Wasps 



still manifests stop at that; and, though Irri- 

 tability of the organs seems annihilated for 

 good, I have nevertheless succeeded in arous- 

 ing slight signs of it. Having placed some 

 recently exhumed and absolutely motionless 

 Weevils in a bottle containing sawdust moist- 

 ened with a few drops of benzine, I was not a 

 little astonished to see their legs and antennae 

 moving a quarter of an hour later. For a 

 moment I thought that I could recall them to 

 life. Vain hope 1 Those movements, the 

 last traces of a susceptibility about to be ex-

 a second time. I have tried this experiment 

 in some cases a few hours after the murderous 

 blow, in others as late as three or four days 

 after and always with the same success. 

 Still, the movement is feeble in proportion to 

 the time that has elapsed since the fatal 

 stroke. It always spreads from front to

 the whole relapses into immobility, which
