The Primary Larva of the Oil-Beetles 



Those which have thus giddily flung them- 

 selves upon a bit of straw and are allowed 

 to return to their flower do not readily fall 

 a second time into the same trap. There 

 is therefore, in these animated specks, a 

 memory, an experience of things. 



After these experiments I tried others with 

 hairy materials imitating more or less closely 

 the down of the Bees, with little pieces of 

 cloth or velvet cut from my clothes, with 

 plugs of cotton wool, with pellets of flock

 do on the bodies of the Bees, they soon con- 

 vinced me, by their restless behaviour, that 

 they found themselves as much out of their

Let us now offer them live insects and, first 

 of all, Anthophorae. If the Bee, after we
