HEARING IN INSECTS. 



THE speech of Mamilius, in the Winter's Tale,- 



I will tell it softly,

shows that Shakspeare had a more accurate know- 

 ledge of insects, than two of our most distinguished 

 naturalists Linnaeus and Bonnet, who are disposed 

 to deny that insects can hear at all. " Passing by a 

 hedge," says the latter, " upon which there was a 

 nest of common caterpillars (Clisiocampa neustria?), 

 I remarked that the sound of my voice appeared to 

 incommode them, for when I spoke they briskly agi-

It would have been well, however, if Bonnet had

 way, altogether independent of the sound of his voice. 

 We have repeatedly watched by the hour these cater- 

 pillars repeating the jerks in question, when it could
