In  this  work  there  are  many  facts  and  mnch  observation  from
die  Authors  own  experience,  which  may  be  useful  to  those  who
liave  otherwise  some  knowledge  and  discernment ;  but»  through*
out  the  whole  work,  there  is  such  total  want  of  method,  arrange-
ment, system,  or  decision,  that  in  my  humble  opinion,  it  can  be
of  little  use,  and  may  jM-ove  very  perplexing  to  those  who  are  yet
to  learn.  The  distinction  of  the  genera  of  diseases,  the  distinc-
tion of  the  species  of  each,  and  often  even  that  of  the  variedest  I
hold  to  be  a  necessary  foundation  of  every  plan  of  physic,  whe-
ther dogmatical  or  empirical.  Bot  very  little  of  this  distinction
is  to  be  found  in  the  work  of  Mr.  Lieutaud  ;  and  in  his  preface  he
tells  us,  that  he  meant  to  neglect  such  argvia  sedmUtas.  'And  indeed
lus  method  of  managing  his  subject  must  certainly  interrupt  and
retard  all  methodicafnosology.  His  arrangement  of  diseases  is
according  to  no  affinity,  but  that  of  the  slightest  and  uninstruc-
live  kind,  the  place  of  the  body  which  they  happen  to  afiect.  His
GeneraRa  et  incert£seAs^  have  hardly  any  connection  at  all ;  the  ti-
tles Rheumatisms^  Hypocondriasisj  Hydrops^  f<^low  one  anodier.
