g6  Dr,  Darwin  on  a new  Cafe , 8cc, 
eye,  than  to  that  neareft  the  objedt,  as  fo  great  a part  of 
it  would  now  fall  on  the  large  infenfible  part  of  that  eye. 
This  muft  naturally  induce  him  to  view  it  with  the  op- 
polite  eye,  to  which  it  already  appeared  more  brilliant 
and  diftindt : and  this  to  him  would  be  fo  much  eafier  to 
accomplifh,  as  the  infenlible  part  of  the  negledted  eye 
was  great  enough  to  receive  as  large  a part  of  an  object 
as  is  ufually  viewed  at  once  with  accuracy,  and  hence 
would  not  confufe  the  vilion  of  the  other. 
I muft  beg  leave  to  add,  that  by  wearing  the  artificial 
nofe  he  has  greatly  corredted  the  habit  of  viewing  ob- 
jedts  with  the  eye  furtheft  from  them;  and  has  more 
and  more  acquired  the  voluntary  power  of  diredting  both 
his  eyes  to  the  fame  objedt,  particularly  if  the  objedt  be 
not  more  than  four  or  five  feet  from  him;  and  will,  I 
believe,  by  refolute  perfeverance,  intirely  corredt  this 
unfightly  deformity.  Nothing  but  the  curiofity  and  no- 
velty of  the  fubjedt  can  excufe  the  length  of  this  paper.
