covered with a kind of armour resembling the tortoise- 
shell in colour and transparency. The plates of which 
this skin is composed are also armed with spines or 
bristles. Two of its six legs are much longer than the 
others, in order to enable the insect to make such won- 
drous leaps, as to raise the body above two hundred times 
its diameter. It is observed, that in one day the Flea will 
devour above ten times its own bulk. The great strength 
and agility of the Flea are well known, from the exhibi- 
tion of the Industrious Fleas.
