 when  it  is  dry,  it  cannot  be  feparated  without  damaging  the  web.  The  Spider performs  the  
 fame  operation  at  each  radius,  till  it  has  made  the  whole  circuit;  approaching  continually  
 nearer  to  the  centre  in  a  fpiral ;  nor  does  it  flop  till  the whole  is  completed,  and  made  perfe£ 
 lly  convenient.  
 7 .  WHEN  a web is  torn  but  a  little,  the  Spider repairs  it,  but  not  fo I'egularly  and  elegantly  
 as  the  original  one :  if  the  rent  is  confiderable,  the  animal  prefers making  a  new  web  to  repairing  
 the  old  one.  
 8.  THE  number  of  radii  and  circles  is  not  conftantly  the  fame:  I  have  counted  forty-eight  
 of  the  latter  in fome  webs.  
 9.  NATURE  has  inftrufted  the  young  Spiders  to make  webs,  without  the  education  and  afiiftance  
 of  their  parents.  
 1 0 .  BOTH  fexes  of  the  fame  fpecies make  webs  of  the  fame  fort;  nor  are  the  webs  of  the  
 young  ones at  all  different,  except  in  fize  and  ftrength.  
 11.  IF the end  of  a thread  is  fixed  any  where,  the  thread  comes  from  fome  tubercle  of  the  
 Spider,  in  a manner  fpontaneoufly  as  it  walks  along;  otherwife  not.  
 12.  THIS  thread,  whether  it  be  drawn  out  by  the  hand,  or  emitted  voluntarily  by  the  
 animal,  is  all  of  one  continued  length.  
 13.  I  DOUBT whether  any  one  has  attempted  to  guefs  at  the  manner  in  which  the i^zi/ifr  
 may  retraft  an  emitted  thread  into  its  abdomen ;  and  much  more  whether  any  one  has  
 confirmed the  hypothefis  by  probable  arguments.  At  the  end  of  the  work,  in  the  defcription  
 of  the  Water-Spider,  I  fhall  treat  ihortly  upon  the  fubjeft.  
 1 4 .  WHILST  they  are  at  reft  in  their  webs,  they  hang  from  the  centre  of  the  under  fide,  
 with  their  heads  downwards.  
 15.  THE  females,  atleaft  all which  I have  had  an  opportunity  of  obferving,  die  foon  after  
 they have  laid  their  eggs.  
 16.  T!he genuine  charaSiers  of  thefe  Spiders are :  
 1.  FOUR  eyes,  of nearly  equal magnitude,  placed  in  a  fquare,  in the middle  of  the  forehead  ;  
 the four others, which  ftand  two on each  fide,  varying  a  little  in  fituation  and  fize,  will  be  defcribed  
 according  as  they  differ  in the different  fpecies.  
 2.  THE  fore  legs  are  the  longefl J  the  fécond  pair  next;  then  the  fourth ;  and  the  third  pair  
 is  always  the Ihorteft.

 I N  the  middle  of  June  I  caught  a  male,  which  I  fed  to  the  26th,  in  hopes  of  catching  a  
 female.  But  finding  it  weak,  I  had  it  drawn  immediately  as  at  plate  i,  fig.  5.  On  the  
 27th,  in  the morning,  it  changed  the  fliin,  and  I  fed  it  afterwards  till  the  20th  of  Auguft;  on  
 the  2iil  it  was  found  dead.  All  this  time  no  female  of  the  fame  fpecies  occurred,  nor  any  
 other  male.  After  having  changed  its  Ikin  once,  both  the  marks  and  the  nature  of  the  ikin  
 remained  the  fame.  
 THE  eyes  are  black  and  all of  the  fame  fize,  except  the  two  lafl  of  the  lateral ones, which  are  
 rather  lefs,  and  iland  prominent  from  the  tubercles.  Eight  very  long  crooked  hairs  appear  
 between  the  eyes,  black  near  the  thorax,  and  livid  towards  the  tips.  
 THE  legs  are  black,  of  which  the  four  anterior  ones  are  marked  with  fewer,  and  the  four  
 pofVerior ones  with  more  numerous  circles.  All  of  them  are  downy  and  befet  with  frequent  
 prickles, which near  the  breaft  are  partly  black  and  partly  dulky,  but  towards  the  extremities  
 are  whitifli,  or  even  quite  white.  
 THE  breafl  or  thorax  is  heart-fliaped;  very  flat,  a little  duiky,  abounding  with  a  foft  and  
 fomewhat  greyiih  down.  The  narrovy  border  next  the  legs  is more  inclining  to  white.  
 THE  abdomen  is  ovate  and  downy;  marked  in  a  wavy  manner  with  fmoke-coloured  and  
 reddifli  flames.  The  junfture  by  which  it  is  connefted  to  the  thorax  terminates  beneath,  
 at  about  a  third  part  of  the  abdomen  :  At  the  upper  fide  occurs  a  ring  of  milk-white  hairs.  
 On  the  middle  of  the  upper  part  is  a white  conical  fpot, the  apex  of  which points  to  the  head,  
 and  the  bafe  to  the  tail:  The  tip  is  marked  by  three little  black  fpecks,  one  near  the  tip,  and  
 the other  two  equi-diftant  from  the  bafe.  Below  thefe,  and  within  the  white  fpot,  towards  
 the  bafe,  a  black  mark  is  fituated  of  an  almofl  triangular  fliape,  with  its  bafe  upwards,  and  
 its  point  downwards.  To  the  above-defcribed  figure,  a  white  line  is  added  beneath,  like  a  
 handle or  foot;  fo  that  this with  the  former  gives  the  appearance  of  the  beautiful  pinus  abies,  
 or  fir,  fo  frequently  feen  in  gardens,  except  in  refped  to  colour.  The  whole  of  this  figure  in
