124' DIRECT INJURIES CAUSED BY INSECTS. 



they enter ahouse in the night, the inhabitants are obhged 

 to rise with all speed and run off in their shirts. 



I must next direct your attention to an insect, which 

 perhaps more than any other has in every age been an 

 object of terror and abhorrence — I mean the redoubted 

 scorpion. And though I shall not, with Aristotle, tell 

 you of Persian kings employing armies for several days 

 in destroying them ; or, with Pliny, of countries that 

 they have depopulated ; yet my account will not be de- 

 void of that species of interest which the dread of its
