  From  Webster's  Revised  Unabridged  Dictionary  (1913)  [web1913]: 
  Encystment  \En*cyst"ment\,  n. 
  1.  (Biol.)  A  process  which  among  some  of  the  lower  forms  of 
  life,  precedes  reproduction  by  budding,  fission,  spore 
  formation,  etc 
  Note:  The  animal  a  first  contracts  its  body  to  a  globular 
  mass  b  and  then  secretes  a  transparent  cyst  (c), 
  after  which  the  mass  divides  into  two  or  more  parts  (as 
  in  d  e),  each  of  which  attains  freedom  by  the  bursting 
  of  the  cyst,  and  becomes  an  individual  animal. 
  2.  (Zo["o]l.)  A  process  by  which  many  internal  parasites, 
  esp.  in  their  larval  states,  become  inclosed  within  a  cyst 
  in  the  muscles,  liver,  etc  See  {Trichina}.
