I need hardly say that the startled insect 

 would not undertake anything while light 

 prevailed, no matter how dim and tempered. 

 It must have complete darkness, which I 

 produce by means of a cardboard sheath en- 

 closing the jar. By carefully raising this 

 sheath a little, I can surprise the captive at

 will notice that this arrangement is much less 

 complex than that which I used when I 

 wished to see the Sacred Beetle engaged in 

 modelling her pear, the simpler method being 

 made possible by the different temperament 

 of the Copris, who is more easy-going than 

 her kinswoman. A dozen of these eclipsed 

 appliances are accordingly arranged on my 

 large laboratory-table. Any one seeing
