 o f  animals.  It  is  eafy  to  lee  that  this  is rather  a  detail  of  the  lèverai  
 materials  and  Well-known  inftruments  conducing  to  fertility-,*  
 than  the  caufe ;  fertility is owing  to  the  concert},  fitneß,andagree-  
 ment o f all  thefe  ( with  perhaps  lome  volatile}  a&ive  principle,  of  
 which we  know nothing  at  all) ; ' but whence  that  agreement does  
 reliait,  how the materials  ferment,  replace*  connect,  and  invigorate  
 one  another,  how the  veflels chufe  and refufe  (if  I may  fey  fo)s  in  
 coder to produce  the  fertility defired, • is known  only to the  infinitely  
 wife Difpofer  of  all  things,  ever  attentive  to  the  nurture  and  fiip-  
 port of what he  has  created. 
 But  to whatever  caufe  the  fertility  of Earth  is  to  be  affigned,  
 Earth,  it  mult  be  owned,  is  a  moft  fruitful,  univerfal  element;  
 animals,  plants,  metals,  and.  ftoneé,  arife; èut of  it,  andreturn  t#.  
 it  again ;  there,  as  it were,  to  receive  a  new  exiftenee,  and  form  
 new  combinations ;  the  ruins  and  diflohition  of  one  fort, affording1^  
 ftill more and more apt materials  for  the,mofe.plentiful  production-  
 o f others :  in  ftones and metals, we  admire the cöhtihuityf Hardnefs-,  
 and  luftre  of  Earth;  in  plants,  the  loftneis,  variety,  colours,  and?  
 odour;  in  animals,  the  flelh, the bone, and yet an infinite  number  of  
 different  fluids,  in which  this  lupple  element  çan Take  place ;  but  
 riie  greateft wonder  is,  that Earth  is  capablefof  being  fiibtilized  to,  
 fiich  an  exquifite  degree,  as  by  uniting  and  communicating- with  
 fpirit  to  perform  all  animal  functions  given  in  charge  to  it  by  the  
 foul.  This  is  the  higheft  and  utmoft  refinement which,  in  this  
 ftate  o f  being,  Earth  is  capable  of ;  but  that  it -may  be  ftill  farther  
 refinèd,  in order  to  be qualified for a future,  incorruptible,  and- mort'  
 glorious ftate, is  one o f the  great truths which we owe  to Révélation. 
 sect. vii.  In  our  mines,  we  often  find  the Ochrous  Earths of  metals,  the  
 H  nifty Ochre of iron,  which we,  in  Cornwall,  call Gdjfcm,  the  green  
 brown  and  blue Ochres  o f  copper,  the  pale  yellow Ochre  of  lead k,  the  
 Earth‘  brown yellow of tin,  and  the  red Ochre of Bifmuth;  thefe Earths we  
 call  the  feeders  of  the  metals  they  belong  to,  and where  they  are  
 found, the metals are  generally, and very juftly reckoned not to  be far  
 off.  Chalk  is  fcarcely  yet  difeovered  any where  in  Cornwall,  but I  
 have  fiich  a  fample  by me  (though  of a  coarfe  gritt);  brought  from  
 the parifti o f St.  Clare,  as may convince  us that more may be  found  
 than  is imagined  upon  a  diligent  fearch;  a  lump  of fmooth Earth,  
 brought  me  from  the  parifh of Illogan,  of a  chocolate colour,  was 
 k  I  have  fome  lumps  of  this  from  Gwynier  
 downs,  which,  in  its  natural  ftate,  mixes  well  
 with oil,  and  makes  a  {hade  betwixt  the  common  
 light and brown Ochre;  neither fo bright as  
 the former,  nor fo ruddy and warm as  the latter; 
 but  more  upon  the  pink.  This  therefore might  
 probably be  introduced into  painting with  advantage, 
   as  it  is  folid, and  will  not  fly off  (as  the  
 painters fay)  as  the biown  pink,  being a tranfpa-  
 rent  colour,  will;  -
