IV. ZOOPHYTA. 



WORMS. 



Are Mollufca covered with calcareous ha- 

 bitations or /hells, which they carry about 

 with them ; themfelves producing and often, 

 penetrating calcareous bodies- Like infe&s, 

 they are multiplied into a vaft number of 

 fpecies and varieties : and both in form and 

 colours, exhibit fpfendid examples of the 

 power of the Almighty Artificer. 



Are compofite anima's, holding a medium 

 between animals and vegetables. Mod of 

 them take root and grow up into Hems; 

 multiplying lite in their branches and de- 

 ciduous buds, and in the transformation of 

 their animated bloffoms or polypes which 

 are endowed with fpontaneous motion. 

 Plants therefore refemble Zoophytes, but 

 are deftitute of animation and the power of 

 locomotion : and Zoophytes are as it were 

 plants, but furnifhed with fenfation and 

 the organs of fpontaneous motion. Of thefe 

 fome are foft and naked, and are called 

 Zoophytes ; others are covered with a hard 

 fhell, and are denominated Lithophytes. 



V. INFUSORIA. Are extremely minute animalcules, defti- 

 tute of tentacula ox feelers, and generally 

 not vifible to the naked eye. They are 

 moflly found in infufions of various vegeta- 

 ble fubftances ; and after becoming dry, do 

 not revive upon being replaced in moiiture.
