BUR YING-BEETLES : EXPERIMENTS 8 1

 To excavate the soil, our grave-diggers must feel the 

 weight of their dead on their backs. They work only 

 when stimulated by the contact of its fur. Never, never

 This is absolutely confirmed by my two and a half months 

 and more of daily observations. 



The rest of Clairville's anecdote bears examination no 

 better. We are told that the Necrophorus in difficulties 

 goes in search of assistance and returns with companions 

 who assist him to bury the Mouse. This, in another 

 form, is the edifying story of the Sacred Beetle whose
