TONGUE * 
The tongue of a gnat pricks likea needle, and fucks 
like a pump : that of fome of the lepidopterous in¬ 
fects is curled like the fpring of a watch * 
JAWS. 
The mandibles of the dragon-fly are naked : this 
little creature is far more deftruffive among infe&s 
than lions in the defart; or fharks in the ocean : this 
ferocious animal feizes every infe£t which paffes by it y 
and breaks its legs at the firftbite.. 
MOUTHS * 
The mouths of infe&s are in general fortified with 
briflles, &c. to keep out hurtful matter. 
. i 
Infe&s which have neither palpi nor fpiral tOngues 3 
have perhaps fome organ concealed* 
SMELLING. 
The fenfe of fmelling is perhaps fituated in the 
palpi, which are continually in motion as if fmelling 
and fearching after food. Thefe organs are clofed to 
fecure the creature from the inconvenience of having 
them Hopped with filth.
