WORM S. 
Are Mollufca covered with calcareous ha- 
bitations or /bells, which they carry about 
with them; themfelves producing and often 
penetrating calcareous bodies. Like infects, 
they are multiplied into a vaft number of 
fpecies and varicties: and both in form and 
colours, exhibit fplendid examples of the - 
power of the Almighty Artificer. 
Are compofite anima’s, holding a medium 
between animals and vegetables. Moft of 
them take root and grow up into ftems; 
multiplying life in their branches and de- 
ciduous buds, andin 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 Lithophyte:. 
Are extremely minute animalcules, defti- 
tute of fentacula 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 
50t revive upon being replaced in moiiture.
