Dear  Sir, 

I  could  not  hefitate  a  moment 
about  the  Perfon  to  whom  I  {liquid  dedicate 
the  following  EfTay.  Our  long  and  intimate 
friendfhip,  with  our  frequent  conventions  up- 
on the  advantages  that  might  be  derived  from 
a  New  Anatomical  Nomenclature,  led  me 
unavoidably  to  think  of  You.  Whether  the 
Public  will  approve  or  condemn  the  attempt  I 
have  made,  or  whether  they  will  even  deign 
to  take  notice  of  it,  I  pretend  not  to  fay.  But 
be  that  as  it  will,  the  favourable  opinion  of 
a  Friend  whom  I  highly  refpect,  of  one  fo

You,  ever  be  a  fource  of  inward  fatisfadion

1  he  chemical  analyfis  of  the  fprings,  wheels, 
and  pivots  of  a  watch,  never  can  explain  its 
movements,  nor  its  ufes;  nor  the  chemical  an- 
alyfis of  the  bones,  mufcles,  blood-veffels,  and 
nerves,  their  functions  in  the  animal.  Many 
of  the  functions  depend  evidently  on  mechani- 
cal caufes,  and  many  more  originate  in  a  caufe 
which  feems  to  be  neither  chemical  nor  me- 
chanical. 

In  every  living  organifed  ftructure,  there 
is  plainly  a  power  that  preferves,  regulates, 
and  controls  the  whole ;  directing  at  firft  the 
different  procerTes  in  forming  one  part  of  the 
organs,  afterwards  employing  the  affiftance  of 
the  organs  which  it  has  formed  to  produce 
more,  till  at  laft  it  completes  the  whole  of  the 
fyftem  in  fuch  a  manner  as  to  fuit  its  future 
conveniences  and  wants.  In  thefe  operations

magnitudes,  forms,  numbers,  &c. ;  marking  the 
times,  feafons,  and  circumftances  for  every 
change  in  ftru&ure  or  function  ;  daily  conti- 
nuing to  fupply  the  parts  in  proper  time  and 
in  due  proportion  with  the  vigour  of  life;  and 
carefully  repairing  their  waftes  and  their  inju- 
ries, till  the  period  fixed  for  their  final  diflblu- 
tion.  This  power,  or  rather  this  agent,  phyfio- 
logiils  have  named  the  vital  principle;  though 
not  a  few  are  inclined  to  fuppofe  it,  to  be  the 
effecT:,  rather  than  the  caufe,  of  the  organization. 
They  adopt  an  hypothefis  fimilar  to  theirs,  who3 
finding  a  chemift  always  in  his  laboratory,  are 
led  to  imagine  that  it  could  not  be  he  who 
formed  the  laboratory,  but  the  laboratory,  on 
the  contrary,  that  formed  him.  At  the  fame 
time,  we  mould  err  egregioufly  if  we  afcribed 
the  plan  of  the  fyftem  to  this  vital  principle. 
In  conftru&ing  the  body,  it  acls,  not  like  the 
chemift,  with  any  defign  or  forefight  of  its 
own ;  but,  in  all  operations  that  are  per- 
formed without  either  volition  or  confciouf- 
nefs,  appears  fubordinate  to  a  much  high- 
er Power — to  that  almighty  and  omnifcient 

Being, 


INTRODUCTION.  3 

Being,  who  difpenfes  his  laws  to  the  boundlefs 
univerfe,  and  whofe  laws,  except  by  Himfelf, 
can  never  be  improved,  altered,  nor  abrogated. 
As  in  every  fpecies  of  living  body,  the  indi- 
viduals are,  bating  the  ufual  differences  of  fex, 
all  conftructed  in  the  fame  way ;  and  the  vi- 
tal principle  always  confined  in  its  operations 
to  fpecific  forms,  ftructures,  and  organs,  and 
fpecific   modes    of   connection    and    arrange- 
ment-— it  neceffarily  follows,  that  there  muft 
be  as  many  vital  principles,  fpecifically  di- 
ftinct,  as  there  are  fpecies  of  organifed  ftruc- 
tures.     The  various  phenomena  in  which  they 
agree,  and  in   which   they  differ,   are  to  be 
learned  in  fludying  their  functions,  manners, 
and  habits,  and   in   examining   and   compa- 
ring the  ftructures  which  they  produce :  For, 
like  to  oxygen,   hydrogen,   and  azot,   which 
act  fo  very  important. a  part  in  the  economy 
of  Nature,  they  are  known  only  from  their  ef- 
fects ;  and  however  anxious  thofe  may  be,  who 
can  trull  only  to  the  evidence  of  fenfe,  to  fee, 
handle,  tafte,  and  fmell  them,  they  have  ne- 
ver yet  been  detected  nor  examined  in  a  fepa-

rate  ftate,  and  probably  never  will,  unlefs  the 
belief  and  conviction  of  mankind,  in  this  re- 
fpecl,  appear  an  object  of  greater  importance 
to  the  Author  of  Nature  than  they  feem  to 
have  been  hitherto. 

With  a  knowledge  of  fuch  different  caufes 
operating  within  us,  we,  in  all  phyfiological  in- 
vestigations, mould  carefully  diftinguifh  between 
what  is  chemical,  mechanical,  and  vital ;  and 
endeavour  to  afcertain,  by  due  experiment  and 
obfervation,  the  part  which  each  acts  in  the  fyf- 
tem,  and  how  they  ufually  oppofe,   affift,  and 
regulate  one  another  for  the  general  good.   But 
to  make  thefe  experiments  and  obfervations,  we 
ftiould  likewife   know  how  to  examine  and 
accurately  defcribe  organifed  ftructures.    This 
information  we  are  naturally  led  to  ex  peel  from 
anatomy ;   while,  unfortunately,  anatomy  has 
not  always  in  its  power  to  give  what  we  look 
for.  A  curfory  glance  muft  demonftrate  to  any 
one,  that  thefe  ftructures  are  complex  and  va- 
ried ;  that  much  depends  on  pofition  and  di- 
rection, on  relative  fituation,  connection,  and 
afpedfc ;  and  that  no  clear  or  accurate  defcrip- 

tion

tion  can  poffibly  be  given,  where  a  language 
is  wanting  to  exprefs  thefe  circumftances.  Such 
a  language,  it  is  much  to  be  regretted,  is  not 
at  prefent  known  in  anatomy  ;  although  the 
want  of  it  has  often  been  felt,  often  complain- 
ed of,  and  partial  attempts  frequently  made 
to  remedy  the  evil. 

The  vague  ambiguity  of  fuch  terms  asfupe- 
rior,  inferior,  anterior,  pojlerior,  &c.  has  been 
felt  and  acknowledged  by  every  perfon  the  lead 
verfant  in  anatomical  defcription.  Vicq  D'A- 
zyr,  who  faw  the  confufion  with  which  they 
were  attended  in  comparative  anatomy,  had 
refolved  to  reject  them  as  definite  characleriftic 
expreffions ;  and  perhaps  had  he  ferioufly 
thought  of  their  confequences,  would  have  re- 
jected them  as  occasional  adjuncts.  But  with 
all  refpect  for  fo  great  a  man,  he  faw  more 
clearly  to  point  out  the  error  than  to  remove 
it.  His  terms  occipital,  fyncipital,  and  fron- 
tal, to  denote  three  afpects  of  the  head,  are 
borrowed  from  bones,  none  of  which  are  ever 
confined  to  a  fingle  afped  \  and  his  ufe  of

compounds,  in  which  prepoiitions,  with  a  fenfe 
equivalent  to  our  under,  above,  and  before,  enter 
as  parts,  was  fcarcely  more  than  exchanging  an 
old  error  for  a  new.  His  divifion  of  the  body 
into  numerous  regions  different  from  thofe  ex- 
preffed  by  fuperior,  inferior,  &c.  and  with  the 
intention  to  get  quit  of  thefe  terms,  has  been 
equally  unfuccefsful.  The  divifion  on  which 
they  are  founded  is  natural;  and  fhown,  by 
experience,  to  be  not  only  convenient  and  ufe- 
ful,  but  even  necefTary.  It  was  not  therefore 
the  divifion  that  was  faulty,  but  the  expref- 
fion ;  and  D'Azyr,  notwithstanding  his  new 
arrangement,  is  often  obliged  to  recur  to  the 
old,  and  make  ufe  of  the  language  which  he 
had  condemned. 

Chauffier,  in  his  Tabular  View  of  the  Ske- 
leton, exprefTes  pofition  by  a  reference  to  the 
parts  in  vicinity  or  contact.  Thus  the  two 
extremities  of  the  clavicle  axejlernal  and  aero- 
mial;  the  two  of  the  humerus,  fcapular  and 
ulnar ;  the  two  of  the  ulna,  humeral  and  car- 
pal; the  rows  of  the  carpus,  radial  and  meta- 
carpal; and  the  two  extremities  of  the  meta- 
carpus, 


INTRODUCTION.  7 

carpus,  carpal  and  digital.  When  he  comes, 
however,  to  the  digital  phalanxes,  and  wants 
the  neceflary  terms  of  diftinction,  he  is  forced  to 
invent  for  the  firft,  fecond,  and  third,  or  what  I 
would  call  the  proximal,  medial,  and  diftal 
phalanxes,  the  terms  phalange,  phalangine,  and 
phalangette.  This  method  of  expreffing  pofi- 
tion  by  a  reference  to  the  parts  in  vicinity  or 
contact,  has  long  been  known,  though  hither- 
to too  fparingly  employed.  It  is  attended  with 
peculiar  advantages  in  minute  defcription,  and 
is  a  part  of  the  general  plan  which  is  recom- 
mended in  the  following  Effay.  But  though 
ufeful  in  its  place,  it  muft  be  obvious  that  it 
does  not  fuperfede  the  general  divilion  into 
thofe  regions  denoted  by  the  words  fuperior,  in- 
ferior, &c.  We  defcribe  not  a  country  by  enu- 
merating all  thofe  that  furround  it ;  we  wifh 
to  know  how  each  part  lies  with  refpecl  to  the 
eaft,  weft,  fouth,  and  north,  and  all  their  fub- 
ordinate  divifions  in  the  compafs  ;  and  to  fa-. 
tisfy  the  mind,  muft  alfo  be  informed  of  what 
is  its  general  fituation  on  the  globe.  Although 
I  be  told  that  one  extremity  of  the  clavicle  is 
A  4  Jlernal 


8  INTRODUCTION. 

Jlernal  and  the  other  acromial,  I  may  Hill  whir 
to  know  what  is  the  afpecl:  of  thefe  two  with 
regard  to  the  trunk,  and  what  are  the  afpecls 
of  its  other  four  fides.  More  general  divifions 
here  become  neceffary ;  and  Chauffier  therefore, 
as  well  as  D'Azyr,  who  found  the  neceffity  of 
fuch  divifions,  is  likewiie  obliged  to  have  re- 
courfe  to  the  old  terms  fuperior,  inferior,  he. ; 
or  to  ufe  compounds  of  which  prepofitions  e- 
quivalent  to  before,  under,  above,  conftitute  a 
part. 

In  the  following  EfTay  I  have  retained  the 
ufual  divifions,  and  ventured  only  to  change 
their  nomenclature:  the  intelligent  reader  muft 
decide  on  the  merits  of  the  change  propofed. 
The  general  views  by  which  1  was  guided  are 
explained  in  fome  preliminary  difcuflions  on 
the  nature  of  language  and  of  nomenclatures, 
particularly  the  nomenclature  of  anatomy.  And 
fhould  what  I  have  done  be  compared  to  a 
building,  it  may  be  faid  that  the  general  plan  of 
the  fabric  is  new,  the  feveral  apartments  more 
regular  and  uniform,  more  convenient,  and  ex- 
tenfively  ufeful ;  at  the  fame  time  that  mofl 

of

of  the  materials,  and  fome  fubordinate  parts 
of  the  work,  were  already  prepared,  and  are 
only  new-modelled  and  arranged,  to  fuit  the 
defign  and  outline  of  the  ftructure.  The  terms 
indeed  which  are  here  fuggeiled  are  chiefly 
confined  to  the  expreflion  of  pofition  and  af- 
pect ;  but  are  fo  contrived  as  to  form  an  inde- 
pendently diflincl  nomenclature  for  general  de- 
fcription  in  all  the  different  branches  of  anato- 
my, and  may  be  ufed  while  the  other  names 
continue  as  they  are.  Should  they  fortunate- 
ly meet  with  the  approbation  of  the  public,  I 
(hall  afterwards  (how  their  application  in  de- 
tail ;  and  add,  on  a  general  and  connected  plan, 
the  nomenclatures  of  the  Bones,  Muscles, 
Blood-vessels,  Nerves,  Ligaments,  &c. 

In  the  names  of  the  Bones  few  changes  will 
be  introduced :  there  is  no  good  or  rational 
objection  to  their  ufual  arrangement  into  bones 
of  the  head,  trunk,  and  extremities-;  and  tho' 
fome  of  their  names  might  have  had  originally 
different  meanings,  yet  as  they  have  long  ceafed 
to  convey  them,  and  are  now  entirely  appropria- 
ted 


10  INTRODUCTION. 

ted  to  anatomy,  it  would  anfwer  no  reafonable 
end  to  run  back  to  the  aeras  of  antiquity,  and 
to  conjure  up  ghofts  and  fpe&res  from  obli- 
vion to  confound  and  embarrafs  them  in  their 
prefent  office.  The  depreflions  and  procefTes  of 
the  different  bones  may  probably  require  fome 
kind  of  arrangement,  as  thofe  of  different  forms 
and  ufes  are  at  prefent  exprefled  by  the  fame 
term, 

In  the  names  of  the  Muscles  it  will  eafily  be 
forefeen  that  more  changes  will  be  found  ne- 
cefTary.  Some  are  diftinguifhed  by  fuch  epi- 
thets as  fuperior,  inferior,  anterior,  pofterior ; 
fome  by  the  epithets  oblique  and  flraight ;  fome 
by  the  epithet  ferraius  or  ferrate 'd ;  fome  by  e- 
pithets  defcriptive  of  their  form,  which,  if  they 
be  ufed  as  arbitrary  terms,  and  have  cealed  to 
convey  any  allufion,  are  harmlefs  enough  ;  but 
if  they  happen  to  convey  an  allufion,  or  refer  to 
characters  that  are  found  only  in  the  human 
body,  they  naturally  become  a  fource  of  am- 
biguity, and  when  limited  in  fenfe  can  feldom 
be  extended  to  comparative  anatomy. 

Some 


INTRODUCTION-  II 

Some  names  are  a  kind  of  defcriptions, 
pretending  to  explain  ufes  and  functions, 
which  thofe  who  impofed  them  did  not  un- 
derftand.  In  all  cafes  thefe  defcriptions  are 
extremely  imperfect ;  often  are  falfe ;  and 
fhould  we  creduloufly  receive  them  as  com- 
plete, and  proceed  to  reafon  upon  them  as 
data,  they  muft  always  lead  to  erroneous 
conclufions.  On  this  principle  fome  mufcles 
are  named  pronators  and  fupinators  of  the  ra- 
dius;  fome  flexors  and  extenfors  of  the  car- 
pus ;  as  if  thefe  were  the  only  mufcles  con- 
cerned in  performing  fuch  movements.  Now 
every  anatomift  certainly  knows,  that  all  the 
digital  flexors  and  extenfors  that  arife  from  the 
humerus  or  fore- arm,  muft  like  wife  be  flexors 
and  extenfors  of  the  carpus ;  that  the  fublimis, 
the  radial  flexor,  and  palmaris  longus,  affift 
in  pronation ;  that  the  fupinator  radii  longus 
brings  the  arm  to  the  middle  pofition,  be- 
tween pronation  and  fupination,  and  then 
adls  as  a  flexor  of  the  fore- arm ;  that  the  bi- 
ceps, attached  to  the  fcapula  and  radius,  is 

an 


12  INTRODUCTION. 

an  extenfor  of  the  humerus,  a  flexor  of  the  ra- 
dius, and  one  of  the  moil  powerful  of  its  fupi- 
nators;  while  other  mufcles,  as  the  extenfor  ter- 
tii  internodii  pollicis,  although  indirectly,  occas- 
ionally affifts  it,  in  that  office.  From  the  variety 
therefore  of  functions,  in  which  mufcles  attached 
to  the  bones  are  ufually  concerned,  every  name 
impofed  with  a  view  to  denote  thefe  functions 
muft  either  be  uncommonly  long,  or  extreme- 
ly imperfect,  with  regard  to  defcription  ;  and 
if  any  fuch  be  retained  in  anatomy,  it  ought  to 
be  intimated  that  the  function  implied  is  mere- 
ly the  function  that  characterifes  it,  and  not 
the  only  one  it  performs. 

Of  all  the  names  that  have  been  hitherto  im- 
pofed on  the  mufcles,  the  beft  are  thofe  which 
are  made  to  diftinguilh  them  by  their  origin 
and  infertion,  or  the  attachments  at  their  op- 
pofite  extremities.  This  was  certainly  demon- 
ftrated  by  Window  ;  although  the  great  and 
accurate  Albinus,  who  had  the  writings  of 
Window  before  him,  feems  to  have  thought 
fctherwife.     Moft  anatomifts  are  pleafed  with 

fuch 


INTRODUCTION.  .      13 

fuch  names  as  flylo-gloflus ■,  ftylo-hyoideus,  fly- 
lo-pharyngeus ;  and  have  often  regretted  that 
all  other  mufcles  were  not  named-  and  diftin- 
guifhed  in  a  fimilar  manner.  It  was  to  com- 
ply with  this  general  wifh,  and  their  own  opi- 
nions upon  the  fubjec%  that  Chauflier  and  Du- 
mas have,  each  on  thefe  principles,  given  us  a 
new  nomenclature  for  the  mufcels ;  although, 
in  the  execution  of  their  plan,  they  perhaps 
have  not  fully  anfwered  expectations.  Unfor- 
tunately imagining,  that  a  principle,  if  right, 
could  not  be  carried  too  great  a  length,  they 
feem  to  have  forgotten  the  old,  though  juft,  ob- 
fervation  of  the  poet,  that 

Eft  modus  in  rebus;  funt  certi  denique  fines, 
Ultra  citraque  nequit  confiftere  re6tum. 

Such  names  are  admirably  calculated  for  muf- 
cles that  have  only  a  fimple  origin  and  a  fimple 
infertion ;  but  where  the  origins  and  infer- 
tions  are  numerous,  the  name  that  pretends  to 
enumerate  the  whole  muft  often  run  out  to  the 
length  of  a  fentence.  It  will  therefore  be  dif- 
ficult to  reconcile  the  anatomift  to  fuch  names 

as

As  names  were  intended  to  mark  objects  in  a

oufnefs  of  defcription,  to  accelerate  intercourfe, 
and  to  make  our  language  keep  pace  with  our 
ideas;  any  attempt  to  reverfe  the  procedure,  to 
check  the  natural  ardour  of  the  mind,  to  retard 
its  operations,  and  increafe  the  difficulty  of  lite- 
rary intercourfe,  appears  to  be  rather  a  retro- 
grade  flep  in  the  way  of  improvement.  Birth, 
marriage,  funeral,  and  triumph,  are  four  words 
each  of  them  denoting  a  group  of  circumftances.

ral  names,  we  made  ufe  of  minute  and  parti- 
cular defcriptions,  the  day  would  fail  before 
we  could  inform  them  that  we  had  been  wit- 
neffing  a  birth,  a  marriage,  a  funeral,  and  a 
triumph. 

Many  names  in  Dumas  are  liable  alfo  to  an- 
other objection:  Beiides  admitting  fuch  words 
as  intus,  extus,  intra,  extra,  fus,  and  fous,  he  has 
often  founded  his  names  on  circumftances  that 
are  peculiar  to  the  human  fpecies.  Mufcles  of 
limilar  fituations  and  functions  have  not  the 
like  origins  and  infertions  in  all  animals;  and 
if  we  mould  always  vary  the  name  with  the 
varying  circumftances  on  which  it  is  founded, 
we  (hould  often  imagine  things  to  be  different 
which  in  all  effential  points  are  the  fame. 

In  many  cafes  a  different  arrangement  would 
exhibit  the  origin  and  infertion  of  mufcles 
without  the  affiftance  of  long  names.  Sup- 
pofe  that  one  genus  of  mufcles  were  the  muf- 
cles attached  to  the  humerus  by  infertion,  it 
would  furely  be  unneceifary  to  mention  this 
circumftance  in  the  name  of  every  individual

i6  Introduction. 

mufcle.  Suppofe,  again,  that  thefe  mufcles  of 
the  humerus  were  fubdivided,  according  to 
their  origins,  into  mufcles  of  the  fpine,  fternwn, 
clavicle,  and  fcapula,  it  would  be  equally  un- 
necessary, after  knowing  what  mufcles  origi- 
nate in  the  fcapula  and  terminate  in  the  hume- 
rus, to  repeat  the  information  in  the  name  of 
each  mufcle.  Would  it  not  be  fufficient,  after 
knowing  where  they  originate  and  terminate,  to 
mark  them  by  fome  individual diilindion,  which 
would  not  require  a  very  long  name?  nor  would 
it  be  neceffary  to  mark  every  individual  diftinc- 
tion,  but  the  moil  obvious  and  chara&eriftic, 
leaving  all  the  reft  to  be  noticed  in  the  hiftory 
and  the  defcription.  Thus  fterno-humeral,  or 
fterno-uumeren,  could  poffibly  lignify  no  other 
mufcle  than  the  pecloralis  major ;  although 
this  mufcle,  upon  examination,  would  be  found 
to  originate,  not  only  from  the  fternum,  but 
ribs  and  clavicle  ;  two  origins,  which  might 
be  omitted  at  leaft  in  the  name,  as  they 
are  common  to  fome  other  mufcles  inferted  in 
the  humerus,  to  the  deltoid  for  inltance,  which 

arifes 


INTRODUCTION.  17 

arlfes  from  the  clavicle,   and  latiffimus  dorfi, 
part  of  which  arifes  from  the  ribs. 

The  mufcles  have  been  clafTed  according  to 
their  flrata,  and  according  to  the  different  re- 
gions which  they  occupy  for  the  purpofe  of 
diffection ;  they  have  alfo  been  clafTed,  by  Cow- 
per  and  others,  according  to  the  bones  in 
which  they  are  inferred;  while  Winflow,  to 
fhow  a  more  general  connection,  has,  in  regu- 
lar order,  enumerated  the  bones,  with  their 
mufcular  attachments,  whether  by  origin  or 
by  infertion.  This  method,  if  the  mufcles 
which  originate  and  the  mufcles  which  termi- 
nate in  every  bone  had  been  feparately  arran- 
ged, would  have  fuperfeded  the  neceffity  of 
Cowper's,  and  would  itfelf  have  been  greatly 
improved,  had  the  remaining  attachments  of 
the  mufcles  been  exhibited  according  to  their 
origin  and  infertion  in  lateral  columns.  To 
illuflrate  the  idea  which  I  mean  to  convey, 
fuppofe  that  we  took  the  mufcles  of  the  hume- 
rus by  way  of  example,  I  would  form,  in  the 
firft  place,  three  diftincT:  columns,  as  reprefent- 
ed  in  the  following  Scheme.

mufcles  originating  to  follow  next,  and  their 
names  to  be  printed  in  a  different  character,  the 
more  readily  to  ftrike  the  eye. — The  column  on

ferted, and  the  other  origins  which  the  mufcles 
originating  may  happen  to  poffefs  beiides  the

in  the  humerus  partially  or  wholly  ;  and  any 
terminations,  mould  there  be  fuch,  that  they

of  a  mufcle  means  nothing  more  than  what  is  in 
general  its  molt  fixed  point;  and  that  the  part 
in  which  it  terminates  may,  by  the  action  of 
other  mufcles,  be  occalionally  made  the  mofl 
fixed  of  the  two:  thus  the  fcapula,  for  inftance,

20  INTRODUCTION* 

by  reverfing  the  order,  may  fometimes  b£ 
made  to  move  on  the  humerus,  and  the  hume- 
rus on  the  fore-arm,  by  the  fame  mufcles  that 
made  the  fore- arm  to  move  on  the  humerus, 
and  the  humerus  on  the  fcapula. 

A  tabular  view  of  this  kind  would  exhibit  a 
very  general  connection  and  mutual  depen- 
dence of  various  movements,  though  it  would 
not  be  fufficient  to  explain  the  motions  of  the 
animal  fyftem.  In  this  Eflay  I  have  given  fome 
idea  of  the  numerous  combinations  into  which 
the  mufcles  are  capable  of  entering ;  although 
thefe  Combinations  are  not  fo  numerous  as  the 
various  pofitions  which  they  produce :  For  fup- 
pofe  that  the  fore-arm,  during  its  flexion,  fhould 
defcribe,  by  the  points  of  the  fingers  extended, 
the  fegment  of  a  circle,  of  which  the  elbow- 
joint  is  the  centre,  that  fegment  may  be  di- 
vided into  more  than  a  hundred  thoufand  parts, 
eaiily  diftinguifhable  by  the  naked  eye :  Now 
at  each  of  thefe  parts  the  flexor  and  extenfor^ 
by  acting  with  equal  degrees  of  force,  can  ar- 
reft  the  motion,  and  retain  the  arm  in  as  many 

thoufand 


'    /  INTRODUCTION.  21 

thoufand  different  poiitions.  From  this  we  may 
be  able  to  form  fome  idea,  though  vague  and 
general,  of  the  immenfe  variety  of  poiitions 
which  a  fmall  number  of  mufcles  can  produce, 
that  are  capable  of  entering  into  fome  millions 
of  different  combinations ;  feeing  that  two, 
confined  entirely  to  the  fimple  motion  of  flexion 
and  extenlion,  on  the  fame  plane,  can  produce 
fo  many. 

The  names  which  allude  to  the  functions  of 
mufcles,  and  thofe  which  diftinguifh  them  by 
origin  and  infertion,  have,  from  an  opinion 
that  they  were  data,  which,  with  little  addi- 
tion, were  fufficient  to  explain  the  animal  mo- 
tions, been  generally  deemed  of  more  im- 
portance than  they  really  are.  An  accurate 
knowledge  of  their  feveral  attachments  is  cer- 
tainly neceffary;  but  as  moil  of  the  motions  are 
in  the  diagonal  of  different  forces,  and  per- 
formed by  a  number  of  mufcles  at  a  time,  to 
underftarid  thefe  motions  completely,  we  mould 
know  all  the  organs  concerned,  the  joints  and 
the  ligaments,  as  well  as  the  mufcles ;  and  of 
B  3  the 


22  INTRODUCTION. 

the  mufcles,  not  only  their  names,  their  origins, 
and  infertions,  but  their  relative  ftrength,  poll- 
tion,  and  direction,  and  efpecially  how  they 
combine  and  co  operate  ;  and  if  we  undergo 
all  this  trouble,  in  order  to  explain  the  animal 
motions,  we  ought  furely  to  know  what  we  are 
in  fearch  of,  and  be  able  to  fay  what  thefe  mo- 
tions are.  The  firft  thing  then  to  be  done  is 
to  find  out  the  motions ;  to  clafs,  arrange,  and 
diftinguifh  them  by  names,  from  our  remarks 
on  the  living  body,  where  they  are  bed  obfer- 
ved  and  afcertained.  The  anatomift  and  phy- 
fiologift,  in  examining  the  fubject,  have  then  to 
point  out,  in  their  demonstrations,  how  each  is 
produced,  and  by  what  organs.  The  head,  to 
make  ufe  of  the  common  language,  moves  for- 
wards, backwards,  to  each  fide,  and  in  all  the 
intermediate  directions ;  I  would  a&here,  How 
thefe  different  motions  are  performed,  and  by 
what  mufcles  ?  Let  us  take,  for  example,  the  mo- 
tion forwards;  and  not  to  confufe  the  defcrip- 
tion  with  too  minute  an  inveftigation,  let  us  fup- 
pofe  that  the  fterno-rnaftoids  alone  perform  that 

motion.

motion.  The  fternal  extremities  of  the  clavicles, 
to  which  they  are  attached,  muft  firft  be  fixed 
by  the  intercoftals  and  abdominal  mufcles;  and 
the  fcapular  extremities  by  the  mufcles  of  the 
fcapula,  humerus,  and  thetwofubclavii.  Suppofe 
now  that  the  fterno-maftoids  are  ready  to  act, 
and  to  bring  the  head  in  the  diagonal  between 
their  forces,  What  are  the  mufcles  employed  to 
prevent  the  lateral  and  rotatory  motions  of  the 
neck  ?  What  are  the  mufcles  oppofed  to  the 
action  of  the  fterno-maftoids,  and  to  limit  their 
effects,  if  it  be  necefiary  to  fix  the  pofition  ? 
What  are  the  mufcles  if  we  ftand  erect  that 
balance  the  body  upon  thus  changing  the  pofi- 
tion of  the  head  ?  and,  What  is  the  manner 
in  which  they  co-operate  in  order  to  produce 
what  is  intended?  Were  we  accuftomed  to 
put  fuch  queftions  frequently  to  ourfelves  with 
regard  to  the  motions  and  pofitions  of  the  fyf- 
tem,  and  to  ftudy  their  anfwers,  we  might  foon 
acquire  a  more  perfect  knowledge  of  mufcular 
action  than  we  have  at  prefent ;  be  better  pre- 
pared to  treat  cafes  of  luxations  and  fractures ;

and  to  place  the  parts  in  eafier  attitudes  after 
reduction.  Our  progrefs,  too,  would  be  great- 
ly facilitated  by  a  tabular  view  of  the  principal 
politions  and  motions  of  the  fyftem,  exhibiting 
Under  each  the  feveral  mufcles  that  act-  as  fix- 
ers, motors,  antagoniils,  directors;  and  leaving 
the  manner  in  which  they  combine  to  produce 
their  diagonal  or  compound  motions;  the  man- 
ner in  which  their  levers  are  lengthened  or 
fhortened  *  ;  and  the  manner  in  which  mem- 
branes, ligaments,  articulations,  and  cartilages, 
by  their  ftrength,  flrudture,  elafticity,  or  gra- 
vity, 


*  The  variation  of  the  centre  of  motion  between  two 
antagonift  mufcles ;  the  confequent  change  that  necefTarily 
takes  place  in  the  relative  length  of  their  two  levers ;  the 
manner  in  which  their  mechanical  power  is  thereby  either 
increased  or  diminifhed ;  and  the  manner  in  which  their 
contra&ile  power  is  made  to  undergo  a  fimilar  change  by 
the  convexity  or  concavity  of  the  joints  over  which  they 
pafs  to  the  place  of  their  infertion — are  all  curious  fubje&s 
of  inquiry,  and  if  underftood  might  illuftrate  many  interefK 
ing  phenomena  in  the  animal  ceconomy. 


INTRODUCTION.  Jg 

vity,  confpire  to  limit,  regulate,  or  antagonife 
them,  to  be  explained  in  a  feparate  defcrip*- 
tion. 

The  celebrated  Winflow  had  a  general  idea 
of  fuch  a  plan,  when  he  divided  the  motions 
of  the  fyftem  into  thofe  of  the  head,  trunk,  &c. 
and  under  each  enumerated  the  feveral  muf- 
cles  concerned,  with  their  attachments.  But 
although  he  knew,  he  has  not  exprefTed  the 
neceflary  connection  between  diflant  motions 
in  preferving  the  equilibrium  and  poiition ; 
nor  has  he  divided  the  motions  of  the  parts  in- 
to different  kinds,  nor  mown  how  the  mufcles 
combine  and  co-operate  in  performing  each, 
by  producing  their  effects  in  various  diago- 
nals. 

In  the  Vascular  System  comparatively  few' 
changes  will  be  neceffary,  with  refpect  either  to 
names  or  arrangement.  Many  of  the  vefTels  are 
well  named  from  their  fituation,  or  from  the  or- 
gans on  which  they  are  ramified ;  but  improperly 
diftinguifhed  by  fuch  epithets  asfuperior,  infe- 
rior, 


2,6  INTRODUCTION. 

rior,  anterior,  poflerior%  &c.  and  fometimes  not 
diftinguifhed  at  all  by  fuch  epithets  as  humeral 
and  femoral,  that  occafionally  are  employed  to 
exprefs  two  very  different  relations.  Thus  an 
artery  is  humeral  when  it  runs  along  the  courfe 
of  the  humerus,  and  likewife  humeral  when  it 
enters  the  bone  to  fupply  it  with  nourifh- 
ment. 

When  they  are  diftinguifhed  by  the  epithet 
of  the  organ  on  which  they  are  ramified,  it 
often  happens  when  the  organ  has,  or  has  had, 
two  names,  that  the  name  of  the  artery  alludes 
to  the  one  which  is  leaft  in  ufe,  or  to  one  that 
is  obfolete.  Thus  the  arteries  and  nerves  of  the 
diaphragm  are  called  phrenic,  containing  an 
allufion  to  its  old  name  phren.  The  arteries 
of  the  flomach  are  all  gaftric,  and  thofe  of 
the  omentum  all  epiploic,  referring  to  the 
names  gafler  and  epiploon.  In  the  fame  way, 
a  mufcle  of  the  tongue,  one  of  the  branches 
of  the  fifth  pair  of  nerves,  and  the  large  ar- 
tery, are  all  lingual,  from  an  allufion  to  its 
Latin  name  lingua;  while  its  other  mufcles- 

and 


INTRODUCTION.  2J 

and  nerves  are  gloffal,  from  an  alluiion  to  its 
Greek  name  glojfa. 

To  remove  this  redundancy  of  language,  eve- 
ry organ  mould  have  one  name,  and  but  one 
only  ;  and  to  that  name  the  a-llufions  contain- 
ed in  the  names  of  its  mufcles,  nerves,  arteries, 
&-c.  ought  to  refer.   In  determining,  however, 
which  of  the  names  ought  to  be  retained,  fome 
difcretion  will  certainly  be  requifite.     For  my 
own  part,  I  would  always  prefer  that  name 
which,  ceteris  paribus,  is  likely  to  be  attended 
with  the  feweft  changes  in  the  prefent  nomen- 
clature.   Thus  I  would  prefer  glojfa  to  lingua, 
as  mod  of  the  references  there  are  to  the  Greek, 
and  exprefled  in  compounds  of  the  Greek  lan« 
guage,  none  of  whofe  parts  would  fo  readily 
unite  with  the  word  lingual  as  they  do  with 
gloffal,  a,  union  to  which  the  eye  and  the  ear 
have  both  been  accuftomed :  on  the  other  hand, 
lingual  enters  into  no  compound  ufed  in  ana- 
tomy, and  the  term  gloffal  might  be  fubftitu- 
ted  for  it,  with  few  changes  and  no  inconve- 
niency. 

Another 


28  INTRODUCTION. 

Another  objection  to  the  prefent  nomen- 
clature of  the  vafcular  fyftem  is,  that  ma- 
ny of  the  trunks,  confidered  as  wholes,  have 
no  names  by  which  they  are  or  can  be  diftin- 
guifhed;  while  the  feveral  parts  of  which  they 
are  compofed  are  regularly  defcribed  as  diftinct 
veffels.  Thus  we  have  gotten  a  fubclavian  ar- 
tery, an  axillary  artery,  and  a  humeral  artery, 
all  parts  of  the  fame  trunk,  which  has  not  it- 
felf  received  any  name.  We  have  alfo  a  com- 
mon iliac  artery,  an  external  iliac  artery,  a  fe- 
moral artery,  and  a  popliteal,  all  continuations 
of  another  trunk,  which  likewife,  as  a  whole, 
ftill  remains  namelefs.  This  defect  is  the  lefs 
excufable,  as  the  nomenclature  is  already  over- 
loaded with  a  number  of  names  belonging  to 
trifling  and  irregular  branches ;  as  may  be  feen 
in  Murray's  defcription  of  the  fmaller  branches 
of  the  cceliac,  ophthalmic,  the  fubclavian,  in- 
ternal iliac,  &c.  In  thefe  defcriptions,  it  muft 
be  confeffed,  he  has  imitated  Haller ;  a  name 
whofe  influence  muft  always  be  great  while 
anatomy  is  regarded  or  fludied  as  a  fcience. 

But 


INTRODUCTION.  »9 

But  Haller,  though  poffefled  of  all  the  learn- 
ing of  the  ancients  and  moderns ;  though  igno- 
rant of  nothing  belonging  to  anatomy  ;  though 
he  added  many  difcoveries  of  his  own;  was 
never  furpalTed,  and  feldom  been  equalled,  in 
collecting  facts,  and  defcribing  them  minute- 
ly— yet  was  little  intent  on  their  general  claf- 
lification  and  arrangement ;  and  provided  he 
could  enumerate  all  that  was  known,*was  little 
difpofed  to  eftimate  the  difference  between  re- 
gular and  irregular  appearances,  or  things  of 
importance  and  of  fmall  value. 

In  the  Nervous  System  flill  fewer  changes 
will  be  necefiary,  if  we  retain  their  numerical 
names ;  and  to  thefe  names  no  forcible  ob- 
jection has  been  made.  They  exprefs  not  in- 
deed the  origin,  termination,  or  functions  of 
nerves ;  but  they  mark  out  the  place  of  the  fe- 
ries  in  which  they  pafs  through  the  holes  or 
interftices  of  the  different  bones ;  and  as  that 
feries  is  clear  and  diflindt,  they  are  ealily  found 
out  on  dhTection.  A  few  varieties  occur  in  the 

mode 


J5  INTRODUCTION. 

mode  of  enumeration ;  but  they  are  triflingj 
and  the  inconvenience  eafily  removed.  The 
qireftion  here  is,  Whether  or  not  fliould 
we  begin  to  enumerate  the  cervical,  dorfal, 
lumbar,  and  facral  pairs,  above  or  below  the 
firft  of  the  vertebrae  in  thefe  regions  ?  Say  above 
or  below,  and  tbe  bufinefs  is  fettled ;  or  let  every 
one  follow  his  own  method,  the  inconveniency 
will  not  be  great.  The  feries,  taken  as  a  whole, 
is  regular,  and  we  know  where  it  commences 
and  terminates;  the  only  difference  is  about  the 
commencement  and  the  termination  of  thefe  di- 
viiions.  Dumas,  in  writing  upon  this  fubject, 
has  confounded  two  things  that  are  perfectly 
diftincl.  It  is  not  with  the  nerves  as  it  was 
with  the  mufcles,  when  they  were  diftinguifh- 
ed  by  numerical  names :  in  that  cafe  there 
was  no  feries  or  order  of  fucceffion  but  what 
was  arbitrary;  and  every  anatomift,  unlefs 
when  occalionally  a  little  affifted  by  the  ltrata 
or  layers,  was  left  to  begin  and  end  the  feries 
of  his  own  creation  wherever  he  pleafed.  Af- 
ter knowing  the  feries  in  which  the  primary 

trunks 


INTRODUCTION.  31 

trunks  of  the  nerves  fucceed  one  another,  no 
names  can  be  more  definite  than  the  numeri- 
cal, they  never  fail  to  direct  the  anatomift  to 
the  very  fpot  where  the  nerve  is  to  be  found ; 
whence  he  may  afterwards  trace  it  to  its  ori- 
gin, or  follow  its  branches  to  their  termina- 
tion. 

I  agree  with  this  excellent  phyfiologift,  that 
names,  founded  upon  the  fuppofed  functions  of 
nerves,  would  be  apt  to  miflead,  and  be  the 
means  of  propagating  error  rather  than  fcience; 
but  hardly  can  fee  how  the  trunks  of  nerves 
could  be  named  from  their  origin  and  termi- 
nations. The  fpecimen  he  has  given  in  the 
new  name  of  the  olfactory  nerve,  is  no  flatter- 
ing recommendation  of  his  plan.  He  propofes 
to  diflinguifh  the  trunk  by  the  tzxmjlriato-na- 
rinal;  the  divifion  which  terminates  at  the 
ethmoidal  bone  by  the  term  Jiriato-narinal-etb- 
moidien;  and  the  part  which  is  ramified  on  the

and  branches,  would  not  only  be  exceedingly 
cumbrous,  but  unneceffary.  In  the  fyftem  of 
Linnaeus,  man  belongs  to  the  genus  homo,  to  the 
order  of  primates,  and  the  clafs  of  ma?nmalia  ; 
but  did  it  ever  enter  the  mind  of  that  naturalift 
to  fuppofe  that  the  genus  would  be  better  ex- 
prefTed  by  the  term  mammale  primus  homo,  than 
by  fimple  homo  taken  by  itfelf.  A  name  is  one 
thing,  claffification  another,  and  defcription  a 
third.  From  riot  making  this  neceffary  diftinc- 
tion,  Dumas,  in  trying  to  impofe  names,  is 
conftantly  labouring  at  a  fort  of  claffification 
and  defcription ;  fo  that  his  defcriptions  are 
often  bad  names,  and  his  names  more  frequent- 
ly  worfe  defcriptions. 

In  the  nervous  fyftem,  if  the  trunks  retain 
their  numerical  names,  the  branches,  like 
thofe  of  the  vafcular  fyftem,  might  be  na- 
med from  pofition,  or  from  the  organs  on 
which  they  are  ramified.  To  diftinguifti  at 
leaft  fome  of  the  trunks  by  the  name  of  their 
origin,  and  the  terminations  of  their  different 
branches,  would  fill  a  page  ;  or  fuppofe  that

one  termination  were  preferred,  and  the  reft 
excluded,  this  new  name  could  not  poffibly 
convey  any  idea  of  the  general  diftribution 
and  ramification  more  than  the  prefent. 

To  anfwer  the  purpofes  of  the  medical  prac- 
titioner, and  fometimes  phyfiologift,  the  nerves 
Ihould  likewife  be  claffed  in  a  manner  different 
from  that  which  is  ufed  by  the  diffe&or.  The 
difle&or,  if  he  follow  a  regular  method,  be- 
gins at  their  origin,  and  then  proceeds  to  their 
ramifications,  where  he  often  finds  a  number 
of  branches  entering  and  mixing  in  the  fame 
organ  ;  a  number  of  branches  proceeding  from 
trunks,  which  are  placed  at  a  diftance  with  re- 
fped  to  their  origin,  and  which,  in  regular 
anatomical  defcription,  are  not  made  to  follow 
in  the  order  of  fucceffion.  On  the  other  hand, 
the  phyfiologift  and  medical  pra&itioner,  in 
treating  of  the  fundtions  or  difeafes  of  an  organ, 
muft  begin  where  the  anatomift  ended ;  and  in 
their  recollection  trace  the  nerves  from  their  ra- 
mifications back  to  their  origin,  Suppofe  the

the  fyftem  on  which  thefe  are  ramified  ? 
What  are  the  other  connections  which  they 
form?  and,  What  is  the  refult  of  thefe  con- 
nections in  health  and  difeafe  ?  A  tabular  view, 
therefore,  of  the  nerves,  beginning  at  their  ori- 
gin, and  exhibiting  their  branchings  and  an- 
aftomofes ;  and  another,  commencing  at  the 
different  organs,  afpects,  or  regions,  and  retra- 
cing their  connections  back  to  their  origin — 
would  be  highly  ufeful  to  the  medical  practi- 
tioner, the  phyfiologift,  and  comparative  ana- 
tomift.  It  is  true  that  fomething  of  this  kind 
has  frequently  been  done  in  books  of  anatomy, 
but  not  on  the  fame  general  plan  that  is  here 
recommended.  The  nomenclator,  from  fuch 
tables,  might  alfo  derive  confiderable  advan- 
tage ;  and  would  fee  the  -danger  of  claflifying 
objects,  and  of  founding  names  upon  a  con- 
tracted view  of  the  fubjedt.

divifion  feems  to  be  neceffary  befides  that  in- 
to ligaments  of  the  hard  and  ligaments  of  the 
foft  parts  ;  while  a  fubdivifion  merely,  ac- 
cording to  the  regions  which  they  occupy, 
confounds  together  things  that  are  different, 
not  only  in  form,  but  in  ftruclure  and  func- 
tion ;  though  if  an  arranged  and  general  view 
were  flrft  given  of  the  different  kinds  belong- 
ing to  the  bones,  mufcles,  and  vifcera,  a  de- 
fcription  of  each,  according  to  the  feveral  re- 
gions which  they  occupy,  would  then  be  not 
only  natural  but  proper.  Thus  plants  and  ani- 
mals, in  the  fyftem  of  Linnaeus,  are  firft  arran- 
ged by  fome common  properties;  and  then  the 
climates,  countries,  or  places  which  they  in- 
habit, are  ufually  mentioned  if  they  be  known. 
But  in  treating  of  the  general  connections  of 
the  fyfcem,  the  viewT  is  imperfect,  if  we  do  not 
likewife  confider  how  far,  and  in  what  man- 
ner, the  fkin,  the  cellular  fubftance  and  muf- 
cles, the  nerves,  the  blood- velTels,  and  the  ab- 
forbents,  contribute  their  fhare  in  fupporting 
and  forming  the  general  union ;  nor  is  it  only

this  fpecies  of  union,  but  every  connection  or 
relation  whatever  among  the  organs,  that  we 
ought  to  ftudy  and  carefully  examine,  if  we 
mean  to  explain  the  fymptoms  of  difeafe,  and 
many  of  the  lingular  phenomena  of  fympathy. 
Connection,  or  at  leafi  a  degree  of  relation, 
arifes  from  mere  fituation  and  attachment; 
from  being  concerned  in  the  fame  motions  or 
the  fame  pofitions;  from  being  fupplied  by 
the  fame  nerves,  the  fame  arteries,  the  fame 
veins,  or  the  fame  abforbents ;  from  being  en- 
veloped in  the  fame  membrane  ;  from  having 
fomewhat  of  a  fimilar  ftru&ure,  or  fimilar  pro- 
perties, with  regard  to  external  or  internal  a- 
gents ;  and  not  unfrequently  from  being  con- 
cerned in  the  fame  functions.  Thus  the  fkin, 
the  internal  furface  of  the  lungs,  the  inteftinal 
canal,  and  the  kidneys,  befides  performing 
their  peculiar  offices,  all  co-operate  in  difchar- 
girig  a  noxious  fluid  from  the  fyftem ;  and 
when  one  of  them  ceafes  to  perform  its  fhare, 
a  greater  proportion  of  the  bufinefs  or  labour 
falls  upon  the  reft,  till  every  one,  communica-

ting  as  it  were  its  diftrefied  fituation  to  the 
parts  conne&ed,  and  thefe  to  the  parts  con- 
nected with  them,  the  alarm  becomes  general ; 
all  feel  and  all  act  as  if  interefted  in  a  com- 
mon caufe  ;  and  all  co  operate  in  refilling  the 
difeafe,  or  in  their  attempts  to  reftore  health. 

Thefe  ideas  of  extended  connexion  ihould 
prevent  the  nomenclator  from  impofing  names 
that  allude  to  limited  or  partial  functions ;  and 
ihould  naturally  lead  to  this  obfervation,  that 
can  hardly  be  too  often  repeated,    that  we 
want,  not  merely  terms  in  anatomy,  but  gene- 
ral and  connected  views,  a  diftinct  claffification 
and  arrangement ;  and  that  the  nomenclature 
ought  to  be  fo  formed  as  beft  to  promote  and 
facilitate  the   attainment  of  thefe  objects.     In 
our  prefent  nomenclature,  to  give  but  an  in- 
ftance  of  this  inaccuracy  in  claffification,  what 
a  llrange  variety  of  organs,  differing  in  form, 
ftructure,  and  ufes,  is  exprefled  by  the  words 
ventriculus  and  Jinus.

ture?  and  with  a  view  to  particular  objects,

have,  inflead  of  improving  it,  been  only  the 
means   of  loadening  it  with   fynonymes  that 
were,  already  by  far  too   numerous.      Every 
intentional    change  in   a  language    ought   to 
be   made    with    caution    and    care,    and    on 
general    principles    that    regard   the    whole : 
thefe   principles  ihould  likewife  be  fully  ex- 
plained to  the  public,  that  they  may  be  able  to 
judge  of  their  importance:   "  for  however  de- 
lirabie  it  might  be,  fays  Degerando,  to  pofTefs 
a  language  perfectly  methodical,  it  would  be 
an  event  exceedingly  deplorable  if,  under  eve- 
ry frivolous  pretext,   we  were  to  be   infefted  v 
with  the  reftlefs  mania  of  making  nomencla- 
tures.    If  every  profelfor,  for  inftance,  in  his 
lectures,  or  every  author  in  his  writings,  mould, 
on  flight  occanons,  think  himfelf  intitled  to  in- 
troduce a  new  language  of  his  own  creation  ; 
from  fuch  a  mixture  of  different  idioms,   the 
confequence  would  be,  that,  inftead  of  having 
a  methodical  language,  wTe  at  laft  mould  have 
no  language  at  all.     The  diffulion  of  know- 
ledge, from  being  accelerated,  would  be  retard-

originate  on  every  fide ;  and  the  literary  world 
foon  become  a  prey  to  all  the  confufion  of  dif- 
trefsful  anarchy*." 

I  am  fully  fenfible,  and  will  readily  ac- 
knowledge, that  no  changes  in  our  prefent 
nomenclature  ought  to  be  made  without 
weighty  and  important  reafons;  and  that  thefe 
changes  fhould  never  be  extended  beyond 
what  are  its  errors  and  defe&s.  It  were  to  be 
wifhed  that  even  the  mod  weighty  and  impor- 
tant reafons  had  influence  fufficient  to  remove 
thefe :  for  the  fame  Degerando,  who  faw  that 
Reafon  was  often  vanquifhed  in  its  contefts 
with  Prejudice,  proceeds  to  obferve — "  That 
whatever  the  merits  of  a  language  may  be,  if 
it  once  has  received  the  fan&ion  of  time  and 
the  fuffrages  of  mankind,  the  philofopher  will 
find  it  no  eafy  matter  to  change  or  improve  it.

and  its  imperfections ;  but  if  he  prefume  to  of- 
fer to  the  world  the  model  of  another,  though 
more  regular  and  fyftematic,  there  is  no  quar- 
ter from  which  he  has  not  to  expedt,  oppoli- 
tion.  He  will  have,  in  this  daring  and  hardy 
attempt,  to  combat  at  once  the  prejudices  of 
the  vulgar  and  pretenfions  of  the  learned.  The 
former  will  bring  in  a  phalanx  againft  him ; 
all  thofe  ftrong  and  facred  regards  that  are  due 
to  old  and  eftablifhed  cuftoms ;  cufloms  flip- 
ported  by  the  conduct  of  thoufands  who  have 
gone  before  him,  and  the  tacit  approbation  of 
illuftrious  names  who  are  univerfally  held  in 
efteem  and  high  veneration.  The  leaf!  reflec- 
tion is  fufficient  to  convince  us,  that  their  re- 
collections and  their  ideas  mud  reft  upon 
names ;  and  although  erroneoufly,  they  will 
aimoft  unavoidably,  draw  the  conclufion,  that 
it  is  impoffible  to  change  the  one  without  like- 
wife  changing  the  other,  and  throwing  the 
whole  into  diforder. 

"  The  learned,  on  the  contrary,  will  diflike  a 
reform  that  may  appear  to  confer  on  its  author 
a  fort  of  dominion  over  the  fcience.  They  will 

grant, 


INTRODUCTION.  41 

grant,  perhaps,  that  the  language  propofed  is 
preferable  to  that  already  in  ufe ;  but  before 
they  adopt  it,  they  will  require  a  demonftra- 
tive  proof  that  it  is  likewife  the  bed  poffible. 
We  ought  not,  they  will  fay,  to  reject  a  lan- 
guage already  eftablifhed,  unlefs  we  be  aflured 
that  the  one  which  is  to  be  fubftituted  for  it  is 
liable  to  no  fort  of  objection;  or  that  it  will  in 
future  preclude  the  neceflity  of  new  innova- 
tions. If  it  Ihould  happen  to  proceed  on  a 
fyftem,  and  that  fyftem  in  any  refpecl  owe  its 
fupport  to  difputed  facts  or  contefted  opinions, 
the  oppofition  will  be  ftill  more  violent.  Thofe 
who  find  their  opinions  overlooked,  or  the  de- 
cifion  given  againft  them,  will  naturally  be 
difpofed  to  reprobate  the  whole,  and  watch 
opportunities  to  treat  it  with  invectives.  Even 
former  habits  with  the  learned  themfelves,  if 
they  yield  at  all,  will  yield  with  reluctance ; 
for  there  is  evidently  in  the  nature  of  man  a 
ftrong  predilection  for  all  thofe  means  which 
he  has  found  inflrumentally  ufeful  in  promo- 
ting his  fchemes :  and  we  find  the  learned,  as 

well 


42  INTRODUCTION. 

well  as  the  vulgar,  attached  to  the  words 
which  they  have  long  been  accuftomed  to  ufe, 
and  very  often  in  proportion  to  the  labour  which 
they  have  beftowed  on  their  acquifition. 

"  Nor  are  thefe  the  only  fources  of  difficulty 
which  a  new  nomenclature  has  to  overcome, 
or  of  difappointments  which  it  has  to  look  for. 
Be  they  learned  or  unlearned,  the  indifferent 
will  treat  it  with  coldnefs  and  neglect ;  the  in- 
decifive  will  doubt  and  hefitate,  and  withhold 
their  opinion  till  its  fate  be  determined  :  and 
although  it  fhould  anfwer  the  purpofes  intend- 
ed, the  invidious  will  naturally  feel  hurt  at 
feeing  others  attaining  their  object  at  a  lefs 
expence  than  they  did  themfelves ;  for  in  their 
eftimation,  fcience,  like  a  diamond,  fhould  de- 
rive its  value  from  its  rarity,  its  price,  and  the 
difficulty  of  procuring  it;  add  to  this,  that  the 
timid  and  defponding  will,  without  the  trouble 
of  making  the  diftinction,  exprefs  a  diftrufl  in 
all  innovations,  and  the  indolent  fee  nothing  in 
fuch  an  improvement  but  the  grievous  trouble 
of  learning  new  terms ;    while  the   man   of 

words 


INTRODUCTION.  43 

words  will  be  indignant  at  the  thoughts  of  a 
language  whofe  clearnefs  and  precifion  may 
check  the  flow  of  his  loofe  declamations,  or  be 
the  means  of  detecting  his  ignorance." 

From  fuch  a  concourfe  of  difpofitions,  interefts, 
and  habits,  all  combining  to  oppofe  the  introduc- 
tion of  a  new  nomenclature,  Degerando  thinks 
that  its  own  merit  will  have  little  influence  in 
recommending  it  to  notice  and  attention;  and 
therefore  imagines  that  nothing  almoft  but  the 
magical  power  of  a  celebrated  name  ;  a  name 
infpiring  confidence  and  awe,  and  whofe  very 
found  can  filence  the  paflions,  gain  prejudices 
over  to  its  fide,  and  lead  the  judgment  as  it 
were  in  chains,  will  ever  be  fufficient  to  fecure 
to  it  any  thing  like  a  general  reception  among 
thofe  of  the  profeflion.     But  though  I  muft 
confefs  my  high  refpect  for  fuch  an  authority, 
I  am  far,  however,  from  being  of  opinion  that 
men  are  fo  much  the  dupes  of  envy,  prejudice, 
and  meannefs,  as  this  author  feems  to  infinuate. 
— I  know  well  the  numerous  difficulties  which 
the  great  difcovery  of  the  circulation  had  to 

encounter ; 


44  INTRODUCTION. 

encounter  \  and  what  oppofition  was  for  fonie 
time  made  to  the  doctrine  of  abforbents.    But 
the  difference  between  thefe  important  difco- 
veries  and  a  new  nomenclature  is  immenfe. 
Thefe    difcoveries    were    not    forefeen ;   the 
want  of  them  was  not  felt  nor  complained 
of;  men  were  fatisfied  with  what  they  knew 
of  the  courfe  of  the  blood  ;  and  abforption  by 
the  veins  was  an  opinion  which  they  confider- 
ed  as  almoft  capable  of  demonftratibn. — A  new 
nomenclature  is  not  to  be  claffed  with  thefe 
important  and  brilliant  difcoveries.     In  com- 
parifon  with  them,  it  ranks  low  in  the  regiflers 
of  Fame.     As  a  work  of  mere  patience  and 
induftry,  it  afpires  to   no   luftre  or  eclat,  it 
proinifes  no  immortality  to  its  author,  nor  fe- 
cures  to  his  name  any  enviable  marks  of  di- 
ftin£tion  ;  it  is  nothing  more  than  what  anato- 
mifts   have   long   wifhed   for,    a  defideratum 
which  they  have  often  attempted  to  fupply  by 
partial  amendments ;  and  if  a  whole  or  com- 
plete fyftem  be  ftill  wanting,  it  is  probably  be- 
eaufe  no  anatomift  of  rank  or  eminence  would

INTRODUCTION.  45 

fubmit  to  a  talk  where  the  drudgery  was  fo  great 
and  the  profpect  of  reputation  fo  fmall. — This 
nomenclature  is  not  to  be  compared  with  that 
of  Lavoifier ;  it  eftablifhes  no  aera  in  fcience, 
it  announces  no  great  revolution,  nor  is  form- 
ed with  a  view  to  perpetuate  any  illuftrious 
difcoveries. — To  compare  a  fmall  thing  with  a 
great,  it  bears  a  much  nearer  refemblance  to 
the  claffification  and  arrangements  of  Linnaeus; 
which  though  they  have  greatly  facilitated  the 
improvement  of  every  branch  of  natural  hif- 
tory,  yet  imply  fo  little  of  that  enviable  cha- 
racter of  genius,  that  thofe  who  have  impro- 
ved and  enlarged  his  fyftem,  have  feemingly 
thought  it  no  facrifice  of  their  own  reputation 
to  allow  their  large  and  numerous  additions  to 
pafs  with  the  public  under  his  name.  But 
fmall  as  that  credit  may  be  which  is  attached 
to  a  work  of  mere  labour  and  induftry,  the 
claims  of  a  new  anatomical  nomenclature  can- 
not be  great,  even  in  this  view.  It  cannot  pre- 
tend to  inftrucl:  the  learned,  or  to  give  them

dered,  with  a  view  to  illuftrate  fome  of  the 
reafons  on  which  the  propofed  changes  are 
founded. 

In  its  primary  fenfe,  language  is  a  word  fy- 
nonymous  with  Jpeecb;  in  a  general  fenfe,  any 
fpecies  of  ligns  employed  as  expreffions  of  our 
thoughts  or  fenfations,  in  the  glowing  imagery 
of  poetic  figure,  it  is  any  phenomena  prefented 
by  Nature,  fpeaking  as  it  were  to  intelligent 
minds,  and  fuggefting  ideas  which  they  had 
not  before. 

Every  language  employed  by  man  is  one  or 
other  of  two  kinds — it  is  either  natural  or  ar- 
tifical.  We  call  it  natural,  when  its  figns  and 
meanings  are  phyfically  connected ;  when  we 
perceive  the  force  of  it  by  inftinct,  and  under- 
ftand  it  without  explanation :  We  call  it  arti- 
ficial, when  its  figns  and  meanings  have  no- 
thing of  this  phylical  relation  ;  when  the  two 
are  conne&ed  by  fome  accidental  affociation? 
or  by  fome  affbciation  founded  on  previous 
agreement  and  contract.    '

ges,  correfponding  in  number  to  the  five  fen- 
fes ;  although  there  be  few  perhaps  who  have 
thought  of  making  a  language  out  of  fmells 
and  taftes. 

Smells  and  taftes  indicate  feveral  important 
properties  in  animal,  mineral,  and  vegetable 
fubftances  ;  and  more  of  fuch  properties  might, 
doubtlefs,  be  difcovered,  wrere  the  fenfes  to 
which  thefe  figns  are  addrefTed  more  gene- 
rally or  ftudioufly  cultivated.  But  both  fenfes 
being  rather  paflive  in  the  exercife  of  their 
functions,  the  figns  addrefTed  to  them  are  very 
little  under  our  management ;  and  thofe  impref- 
lions  which  they  happen  to  make  on  the  fentient 
organs  are  fo  various  in  various  perfons];  fo  faint, 
fo  permanent,  or  fo  powerful,  that  they  rather 
deter  than  invite  curiolity  to  make  the  attempt. 
They  are  fometimes  fo  violent  as  even  to  affect 
the  ftructure  of  their  organs;  and  generally  raife

which  the  primary  impreffions  are  blunted,  and 
objects  made  to  give  pleafure  or  difguft  which 
formerly  excited  an  oppofite  feeling.  The 
fenfes,  too,  from  being  contiguous,  are  in  dan- 
ger of  having  their  impreffions  confounded, 
particularly  when  the  objects  prefented  exhi- 
bit both  an  odour  and  tafte.  For  thefe  reafons, 
odours  and  taftes,  however  fufceptible  of  com- 
bination and  variety,  and  however  expreffive 
of  certain  diftinctions,  have  feldom  been  em- 
ployed as  the  vehicles  of  thought;  and  the  two 
fenfes,  by  which  they  are  perceived,  feldom 
cultivated  for  any  noble  or  valuable  purpofe. 

The  figns  of  touch,  though  few  in  number, 
and  likewife  imperfect,  have  attracted  more 
general  attention.  At  Mecca,  and  fome  other 
places  of  the  Eaft,  merchants  employ  them 
as  a  medium  of  intercourfe  ;  thrufting  their 
hands  into  one  another's  ileeves,  and  by  means 
of  the  ringers  converfing  together  beyond  the 
poffibility  of  being  feen  or  heard.  The  deaf

of  their  friends,  feeling  what  is  meant,  and  then 
returning  an  anfvver  to  the  touch  inftead  of 
the  eye,  when  they  wifh  to  hold  converfation 
in  the  dark.  The  cafes,  however,  are  extreme- 
ly rare  where  they  can  be  ufed  with  any  ad- 
vantage :  when  thofe  who  converfe  are  remo- 
ved to  the  diftance  of  a  few  feet,  they  become 
ufelefs  ;  they,  befides,  are  fo  few,  fo  indiftincl, 
fo  complex,  and  fo  difficultly  learned,  that 
mankind,  even  in  the  clofeft  intercourfe,  fel- 
dom  refort  to  them,  unlefs  when  impelled  by 
the  ftrong  motives  of intereft  or  neceflity. 

The  vifible  iigns  have  a  much  ftronger  claim 
to  our  notice  ;  they  are  of  a  more  elevated  na- 
ture; are  more  numerous,  diftindt,  and  varied; 
and,  independent  of  their  elegance  and  beauty, 
are  better  calculated  to  exprefs  the  modifica- 
tions of  fentiment.  They  furpafs  all  others  in 
conveying  intelligence  to  a  diftance  ;  and,  ow- 
ing to  the  fenfe  by  which  they  are  difcerned, 
their  entering  in  groups  produces  no  confu- 
fion  in  perception.  The  eye,  w7hich  receives 
them,  marks  inftantaneoufly  the  boundaries  of

tion,  its  colour,  its  form,  and  its  proportion ; 
performing  its  office  with  lingular  difpatch, 
and  in  general  with  accuracy. 

If  vifible  figns  be  not  therefore  commonly  ufed 
as  a  language,  the  fault  is  not  in  the  organs  of 
vifion  ;  like  thofe  of  fmell,  tafle,  and  of  touch, 
they  are  not  fufficiently  fubjecled  to  our  power; 
we  cannot  collect,  tranfport,  nor  appropriate 
them  at  pleafure ;  we  cannot  imitate  them  with- 
out much  labour  and  ftudy ;  and  even  when  the 
power  of  imitation  is  acquired,  we  cannot  fe- 
parate,  combine,  and  vary  the  number,  the 
colour,  the  form*  and  proportions  of  their  dif- 
ferent pictures,  readily  and  with  eafe. — Gef- 
tures,  indeed,  are  natural  expreffions,  but  fa- 
tiguing and  tirefome ;  depend  too  much  on 
feeling,  on  fancy,  or  the  art  of  mimickry ;  and 
would  be,  even  in  a  Rofcius  or  Garrick,  too 
few  in  number,  and  too  little  fufceptible  of  that 
variety  which  is  requifite  in  language.— Ano- 
ther objection  to  vifible  ligns  is,  that  aim  oft

are  luminous,  are  imperceptible  in  the  dark, 
and  can  only  be  ufeful  during  the  day,  or  when 
artificial  light  is  employed.  For  thefe  reafons 
vifible  figns  have  been  alfo  rejecled  as  a  me- 
dium of  intercourfe  in  the  more  ordinary  oc- 
currences of  life  ;  fo  that  of  the  five  fpecies  of 
figns,  the  audible  only  have  been  received  in- 
to general  ufe. 

As  phyfical  caufes,  audible  figns  never  pro- 
duce, like  odours  and  taftes,  pain,  naufea,  or  vo- 
miting ;  and  feldom  are  fo  loud  as  to  injure  the 
organs  to  which  they  are  addreffed.  They  are 
not  confined,  like  the  tangible  figns,  to  imme- 
diate contact;  and  are  not,  like  the  vifible,  de- 
pendent on  light ;  at  the  fame  time  no  figns 
are  more  numerous,  difiincl:,  and  varied,  or  fo 
much  under  management.  We  poffefs  even  a 
fyftem  of  organs  conftrudied  intentionally  upon 
their  account ;  a  fyftem  which  imitates,  cre- 
ates, combines,  feparates,  lengthens,  fhortens, 
raifes,  lowers,  and  varies  them  at  pleafure ;  a 
fyftem  which,  through  nervous  communica-

likewife  of  any  kind,  and  in  any  order,  arrange- 
ment, or  variety  that  fuits  its  tafte.  Nay,  what  is 
more,  the  hands  and  the  feet,  which  under  its 
directions  produce  founds  in  rythmus  and  mea- 
fure,  would,  in  cafes  of  neceflity,  prove  no  im- 
perfect: inftruments  of  its  language ;  but  very 
feldom  has  it  occafion  for  their  affiftance.  Its 
vocal  organs  are  fully  adequate  for  every  kind 
of  audible  expreffion  ;  while  the  power  it  has 
of  thus  procuring  founds  at  its  pleafure,  does 
not  prevent  it  from  deriving  much  curious  in- 
formation from  the  founds  emitted  by  various 
objects  difperfed  throughout  Nature.  By  thefe 
it  is  often  able  to  diftinguiih  the  fpecies  of  an 
animal,  its  paffions,  and  its  feelings ;  by  thefe 
it  often  diilinguillies  likewife  the  mineral  and 
vegetable ;  and  by  attending  to  their  nicer 
fhades  and  varieties  of  tone,  minute  differen- 
ces, that  depend  on  lingular  and  abflrufe  pro-

tenfive,  than  any  addreffed  to  the  other  fenfes. 

Even  written  language  is  the  language  of 
the  ear ;  none  of  its  figns  are  directly  and  im- 
mediately the  figns  of  our  ideas,  but  the  figns 
of  founds,  to  which  our  ideas  are  linked  and 
affociated.  And  here,  might  I  venture  on  a 
bold  figure,  I  would  almofl  fay  that  written 
languages  are  nothing  more  than  the  fhadows 
of  the  vocal ;  for  while  vocal  languages  are  in 
that  ftate  which  we  call  living,  their  written 
languages  are  obferved  to  follow  them  flep  by 
flep  %  to  afTume  their  varying  and  Proteus 
forms;  and  whether  ftationary,  progreffive,  or 
retrograde,  to  undergo  correfponding  changes. 
Even  the  written  language  of  China,  which 
did  originally,  and  does  flill,  in  a  few  cafes, 
anfwer  the  purpofes  of  a  pictured  language,  is, 
upon  the  whole,  more  frequently  employed  as 
a  fymbol  of  fpeech  :  for  allowing  it  to  poffefs 
no  fewer  than  80,000  different  characters,  yet 
that  number  would  be  very  inefficient  to  ex-

Hands  for  a  word  ;  and  the  fame  picture,  like

need  we  here  have  recourfe  to  hypothecs ; 
we  are  pofitively  allured  that  thefe  charac- 
ters have  gradually  become  the  fymbols  of 
founds ;  that  occafionally  they  are  ufed  like  let-

mod  of  their  pictures  reprefented  founds ;  that

the  name  of  the  flower,  the  plant,  or  the  animal, 
the  picture  of  the  object  whofe  name  he  bore 
was  made  to  reprefent  him  in  writing,  but  di-

pictures  were  joined  together,  and  a  word  com- 
pofed  as  of  fo  many  fyllables.  A  fimilar  prac- 
tice is  followed  in  China  ;  a  great  part  of  their 
primary  words  are  monofyllabic.  All  of  thefe 
fyllables  have  pictures,  or  rather  what  were 
originally  pictures;  and  when  you  mean  to 
write  a  word  of  fo  many  fyllables,  you  have 
only  to  write  the  pictures  of  the  fyllables  of 
which  it  is  compofed.  Some  of  thefe  fyllables 
approach  near  to  the  elementary  founds  of  our 
alphabets ;  fo  that  words  are  fpelt  and  written 
in  China  by  the  mutilated  fragments  of  the 
ancient  pictures,  nearly  as  we  write  and  fpell 
them  in  Europe  by  means  of  fyllabic  charac- 
ters and  letters. 

The  firft  ffcep  therefore  in  picture  or  icono- 
graphical  writing  was  to  make  the  figure  ftand 
for  the  name  of  what  it  reprefented  ;  the  fe-

as  much  as  poffible  their  operation  upon  the

ledged to  require  proof ;  and  writers  of  tafle,

gance of  their  diction,  mull  often  reflect,  with 
painful  apprehenlion,  on  the  inftability  and 
tranfient  nature  of  the  perifhing  founds  with 
whiqh  their  literary  fame  is  connected.     But

however  great  their  apprehenfions  may  be,  the 
effects  which  they  dread  cannot  be  prevented.

feology  ;  in  a  new  phrafeology,  caprice  and

Yet,  independent  of  all  thefe  caufes,  lan-

its  very  nature;  each  individual  has  a  voice 
of  his  own,  and  a  manner  of  fpeaking  that  di- 
ilinguifties  him  from  others ;  and  this  diffe- 
rence would  be  Hill  more  confpicuous,  were

cefs  to  the  general  ftandard,  and  where  mod 
are  obliged  to  take  copies  for  their  model,  the 
language  feparates,  almoft  irrefiftibly,  into  dif- 
ferent diale&s  ;  and  each  province,  or  each 
group  into  which  the  feveral  inhabitants  are 
clafTed,  acquires  a  tone,  accent,  and  manner 
peculiar  to  itfelf :  or  fhould  the  province  be- 
come independent,  and  all  its  connection  with 
the  nation  be  dhTolved,  its  dialect  haftens  to 
aiTume  the  form  of  a  different  language.  So 
ftrong  is  this  tendency  to  change,  that  in  ma- 
ny provinces  of  no  great  extent  their  dialects 
are  fub divided  into  dialects;  each  diftric~t,  vil- 
lage, and  hamlet,  fecluded  from  a  regular  and 
frequent  intercourfe,  exhibits  fome  peculiari- 
ties of  fpeech  ;  and  would  feemingly  in  time, 
if  intercourfe  were  ftopt,  acquire  a  diftinct  lan-

On  thefe  principles,  which  can  hardly  be 
denied,  let  us  here  try  to  form  fome  idea  of 
the  number  of  changes  of  which  the  organs  of 
voice  are  fufceptible.  The  mufcles  proper  to 
the  five  cartilages  of  the  larynx,  fuppofing  the 
tranfverfe  and  oblique  arytenoid  to  eonftitute 
but  one,  are  feven  pairs*.  Now  fourteen  muf- 
cles, that  can  act  feparately  or  in  pairs,  in 
combination  with  the  whole,  or  with  any 
two  or  more  of  the  reft,  are  capable  of  pro- 
ducing 16,383  different  movements;  not  reck- 
oning as  changes  the  various  degrees  of 
force  and  velocity,  nor  the  infinitely  varied 
order  of  fucceffion  by  which  they  may  occa- 
fionally  be  brought  into  action.  The  num- 
ber appears  almoft  incredible ;  but  to  leffen 
the  furprife,  it  muft  be  recollected  that  I  fpeak 
not  here  of  the  powers  pofTefTed  by  any  indi- 
vidual,

vidual,  which  will  depend  on  habits  and  cir- 
cumftances,  but  of  the  powers  of  the  vocal 
organs,  confidered  in  the  abftract,  free  from  all 
the  influence  of  cuftom,  equally  indifferent, 
and  equally  difpofed  to  ad  in  any  order  of 
fucceffion,  in  any  combination,  and  with  any 
degree  of  force  and  velocity  of  which  their 
original  powers  were  fufceptible. 

If  the  powers  I  have  mentioned  appear  afto- 
nifhing,  and  able  to  account  for  many  thou- 
fands  of  thofe  varieties  obferved  among  the 
voices  of  the  human  fpecies,  I  have  further  to 
add,  that  the  mufcles  alluded  to  are  only  the 
proper  mufcles  of  the  larynx,  or  the  mufcles 
reftridted  in  their  attachments  to  its  five  carti- 
lages. Thefe  are  but  a  few  of  the  mufcles  of 
voice.  In  fpeaking  we  ufe  a  great  many  more*

the  cartilages,  or  os  hyoides,  and  acting  as 
agents,  antagonifts,  or  directors,  are  conftantly 
employed  in  preferving  the  cartilages  of  the 
larynx  fteady,  in  regulating  the  place  of  their 
fituation,  or  moving  them  as  occafion  requires, 
upwards  and  downwards,  backwards  and  for- 
wards, and  in  every  way,  directly  and  oblique- 
ly, according  to  the  courfe  of  the  mufcular  fi- 
bres, or  in  the  diagonal  between  different  forces. 
Thefe  mufcles,  independent  of  the  former,  are 
fufceptible  of  1,073,741,823  different  combi- 
nations \  and  co-operating  with  the  feven  pairs 
of  the  larynx,  of  17,592,186,044,415,  exclu- 
sive of  the  changes  which  muft  arife  from  the 
different  degrees  of  force  and  velocity,  and  the 
infinitely  varied  order  of  fucceflion  in  which 
they  may  be  brought  into  action. 

But  thefe  are  not  all  that  co-operate  with 
the  larynx,  either  in  forming  or  changing  the 
voice :  the  diaphragm,  the  abdominal  mufcles, 

the

the  intercoftals,  and  all  that  directly  or  indi- 
rectly act  on  the  air,  or  on  the  parts  to  which 
the  chondral  and  hyoidal  mufcles  are  attached, 
contribute  their  fliare.  The  os  hyoides  could 
not  be  raifed  unlefs  the  inferior  maxillary  bone 
were  previoufly  fixed  by  the  temporals,  mafTe- 
ters,  and  internal  pterygoids;  and  a  fimilar  af- 
fiftance  is  likewife  furnifhed  by  feveral  other 
auxiliary  mufcles  that  fix  the  head,  fternum, 
and  fcapula  ;  to  thefe  we  muft  add  fome  pairs 
belonging  to  the  pharynx  and  ifthmus  fauci- 
um,  and  fome  alfo  belonging  to  the  tongue ; 
which,  combining  with  others,  give  to  that  or- 
gan an  inconceivable  variety  of  movement ; 
and  fo  quickly  that,  in  rapid  utterance,  they 
change  its  ftate  three  thoufand  times  in  the 
fpace  of  a  minute^. 

Yet  all  thefe  mufcles,  whether  they  affift  to 
infpire  or  expire,  to  enlarge  or  diminim  the 
cavity  of  the  pharynx,  to  fliorten,  lengthen,  to 

relax

relax  or  render  tenfe  the  trachea,  to  change 
or  fix  the  fituation  of  the  larynx,  to  alter  the 
relative  pofition  of  its  cartilages,  to  enlarge  or 
diminifh  the  aperture  of  the  glottis,  to  give 
the  necefTary  tenlion  to  its  ligaments,  or  arti- 
culate the  voice  as  it  paiTes  through  the  mouth 
— can  neither  feparately,  nor  in  combination, 
produce  an  audible  impulfe  on  the  air  with- 
out a  certain  degree  of  elafticity  and  vibratory 
motion  of  the  trachea,   laryngeal  cartilages, 
and  glottal  ligaments.     Now  this  elafticity, 
though  it  partly  depend  on  the  action  of  the 
mufcles,  yet  it  partly  depends,  at  the  fame 
time,  as  we  learn  from  catarrh,  on  the  ftate  of 
the  membranes  and  glandular  fecretions,   and 
partly,  too,  as  we  alfo  learn,  from  fome  other 
cafes  on  the  ftate  of  the  larynx  and  of  the.  tra- 
chea ;  and  fuppofe  thefe,   as  well  as  the  muf- 
cles,  were  perfectly  fitted  to   perform  their 
functions,  and  to  produce  the  audible  impulfe, 
yet  this  impulfe  is  apt  to  be  varied  by  the  ftate 
of  the  nofe,  fauces,  and  palate,   as  we  learn 
from  feveral  of  their  morbid  affections.     Pro- 
bably, too,  by  the  fize  and  form  of  the  frontal

fphenoidal  and  maxillary  antres ;  and  mod 
certainly  by  the  fecretion,  or  rather  abforption 
of  the  feminal  fluid,  as  we  may  fee  in  the  con- 
fequences  of  caftration. 

Another  fource  of  this  fpecies  of  variety  is 
the  ear,  which  fuperintends  and  dire&s  the 
whole  of  the  vocal  fyftem,  and  without  which 
the  voice  would  be  conftantly  harih  and  unhar- 
monious,  as  may  be  obferved  in  the  fpeech  of 
the  deaf.  To  the  ear  we  muft  add  the  feveral 
pafiions,  each  of  which  lays  claim  to  peculiar 
tones  and  cadences  and  to  modes  of  utterance, 
differing  widely  in  loudnefs  and  rapidity,  and 
in  many  other  fpecific  varieties  not  eafily  de- 
fcribed. 

If  we  turn  our  attention  to  the  manner  in 
which  the  voice  is  articulated,  we  mail  find 
Hill  more  fources  of  variety ;  we  (hall  find 
that,  befides  the  tongue,  the  pendulous  ve- 
lum of  the  palate,  the  palate  itfelf,  the  alveo- 
lar procefTes,  the  teeth,  and  the  lips,  are 
all  concerned  in  the  pronunciation  of  words; 
and  if  we  examine  the  human  lips,  compare 
them  with  thofe  of  inferior  animals,  obferve

their  free  and  extenfive  motion,  with  their  nu- 
merous mufcles  *,  capable  of  entering  into 
524,287  different  combinations,  we  can  hardly 
avoid  being  of  opinion  that  the  human  lips, 
befides  being  calculated  to  anfwer  a  variety  of 
other  purpofes,  were  alfo  intended  by  the  Au- 
thor of  Nature  to  be  organs  of  fpeech. 

I  have  no  doubt  that  here  the  reader's  fur- 
prife  will  recur  at  this  immenfe  variety  of 
power  in  the  vocal  organs ;  and  more  particu- 
larly when  he  reflects  that  the  number  of  pofi- 
tions  which  they  produce  is  infinitely  greater 
than  that  of  their  movements  f.  But  however 
great  his  wonder  may  be,  he  will  furely  recol- 
lect that  thefe  combinations  are  not  deduced 
from  fpeculative  opinions,  but  by  fair  calcula-

thing  like  marvelling  aftonifhment,  I  have  pur- 
pofely  omitted  the  incalculable  varieties  that 
neceffarily  refult  from  the  degrees  of  force  and 
velocity,  and  the  infinitely  varied  order  of  fuc- 
ceffion  in  which  the  mufcles  may  be  brought 
into  action.  He  may  affert,  and  afiert  with 
juftice,  that  no  individual  of  the  human  fpecies 
can  throw  his  mufcles  into  one  thoufandth  part 
of  the  combinations  of  which  I  have  fuppofed 
them  fufceptible.  But  he  mould  remember 
at  the  fame  time,  that  this  reafoning,  as  has 
been  acknowledged,  was  never  intended  to 
fhow  what  are  the  effects  of  mufcles  in  par- 
ticular perfons,  but  to  fhow  their  capacity  and 
original  powers ;  and  from  what  an  exhaufl- 
lefs  fund  of  variety  in  tone  and  voice  they  are 
able  to  furnifh  each  individual  of  the  countlefs 
millions  of  fucceflive  generations  with  charac- 
teriflic  marks  of  diflinction. 

Perhaps  even  in  the  fingle  individual  the 
combinations  of  the  vocal  mufcles  are  more  nu- 
merous, and  more  obvious  than  is  generally  be- 
lieved.    Who,  from  theory,  would  have  ven- 
tured 


78  THE  CHANGES 

tured  to  predict,  what  now  is  a  well  authenti- 
cated fact,  that  the  deaf,  by  attention,  may 
learn  to  fpeak,  and  diftinguifh  all  the  words  of 
a  language  by  their  vifible  changes  in  the  or- 
gans of  voice  ?  Who  that  has  felt  the  varied 
and  powerful  exprefiions  of  the  eyes,  would  have 
imagined  that  fuch  a  number  could  have  been 
produced  by  a  few  mufcles  ?  and,  Who  has 
not  wondered,  and  wondered  again,  at  the  va- 
ried appearances  of  all  the  paflions,  and  of  all 
their  fhades,  in  the  countenance  of  a  Garrick  ? 
And  yet  all  thefe  inftances  muil  fall  fhort  of 
conveying  even  the  mod  diftant  idea  of  the 
powers  I  allude  to. 

To  form  any  thing  like  an  adequate  notion 
of  the  lingular  contrivance  of  the  mufcular 
fvftem,  and  of  the  movements  of  which  it  is 
capable,  we  mud  not  confine  our  examinations 
to  what  is  exhibited  in  two  or  three  prrticular 
perfons ;  we  muft  recollect  that  all  the  mufcles 
are  living  powers ;  that  in  early  life  they  are 
apt  to  contract  habits  with  facility,  and  after- 
wards to  retain  them  with  fuch  inveteracy  as 

to 


OF  LANGUAGE.  79 

to  be  incapable  of  any  exertion  inconfiftent 
with  thofe  in  which  the  previous  habits  had 
been  formed.  We  fee  this  daily  exemplified 
in  the  ufes  of  the  right  and  left  arm ;  and  may 
often  obferve,  that  thofe  who  have  long  been 
accuftomed  to  one  language  find  it  difficult, 
and  fometimes  impoflible,  to  articulate  proper- 
ly the  founds  of  another.  In  thefe  cafes  we 
fee  the  mufcles  inactive  from  difufe,  or  fetter- 
ed under  the  conllraints  of  habit ;  the  habit, 
too,  of  particular  fituations.  In  fuch  circum- 
ftances,  it  is  impoflible  they  can  furnifh  a  cri- 
terion of  what  had  been  their  primary  powers. 
To  form  a  juft  eftimate  of  thefe,  we  muft  look 
back  to  the  more  early  periods  of  life,  view 
them  in  every  diverfity  of  fhade,  in  every  per- 
fon,  in  every  fituation,  conftitution,  and  cli- 
mate ;  we  fhall  then  find  that  whatever  thefe 
be  in  the  adult,  they  were  very  different  at  the 
commencement  of  life's  career. 

All  children  acquire  the  tones,  accents,  and 
articulations  of  thofe  countries  in  which  they 
are  educated  \  an  evident  proof  that,  prior  to 

the 


8o  THE  CHANGES 

the  formation  of  habits,  the  vocal  mufcles  may 
be  brought  to  act  in  any  one  of  the  numerous 
millions  of  combinations  that  have  ever  been 
adopted  by  any  tribe,  family,  or  nation  of  the 
human  race,  and  be  made  to  acquire  the  habit 
of  pronouncing  with  readinefs  and  eafe  any 
one  of  the  almofl  infinite  variety  of  languages 
that  have  been,  that  are,  or  that  ever  Ihall  be, 
on  the  face  of  the  globe.  Even  this  wonder- 
ful diverfity  of  power  is  daily  prefented  to  our 
dbfervation  ;  for  when  we  coniider  that  the 
mufcular  fyftem  is,  with  the  exception  of  a 
very  few  trifling  varieties,  nearly  the  fame  in 
all  individuals,  having  the  number,  form, 
ftru&ure,  fituation,  direction,  and  attachment 
of  its  mufcles  in  every  inflance,  regular  and 
uniform — we  muft  certainly  conclude  that,  un- 
like to  any  thing  we  have  ever  feen,  it  has  the 
power  of  diverfifying  its  actions  in  a  moll  ex- 
traordinary and  uncommon  manner;  and  whdn 
we  fee  it  exhibit  the  flrongly  marked  and  pe- 
culiar differences  in  the  features  of  the  coun- 
tenance, in  the  voice,  the  gait,  and  the  hand-

writing  of  each  individual  in  the  countlefs  mil- 
lions of  paffing  generations;  when  we  fee  it 
the  organ  in  all  their  different  fpecies  of  exer- 
cife,  and  every  exercife  like  their  tone  of  voice 
marked  by  iome  difcriminating  character ;  in 
fhort,  when  we  fee  the  number,  variety,  the 
ftrength,  the  velocity,  and  continuance  of  its 
motions,  in  fome  of  the  more  remarkable  cafes 
of  running,  leaping,  dancing,  riding,  fencing, 
wreftling,  vaulting,  tumbling,  balancing  the 
body,  and  performing  feats  of  legerdemain — in 
the  name  of  wonder,  what  mull  we  think! 
We  muft  furely  think,  with  the  credulous 
and  vulgar,  that  it  is  affifted  by  the  power 
of  magic  ;  or,  with  the  more  enlightened  and 
coniiderate,  that  it  pofTefTes  powers  and  re- 
fources,  of  which,  after  all  our  iludy  and  in- 
quiry, we  are  frill  ignorant. 

With  refpect  to  characleriftic  diftin&ions,  I 
have  mentioned  feveral  fources  of  variety  in  the 
tone  and  articulation  of  voice,  befides  mufcles; 
but  fuppofe  that  mufcles,  acling  as  motors,  fix-

ber*  although  I  have  enumerated  63,  exclu^ 
five  of  others  which  might  have  been  named,, 
thefe  50  mufcles  are  capable  of  entering  into 
1,125,899,906,842,623  combinations,  and  the 
numerous  effects  of  thefe  combinations  may  be 
infinitely  diverfified  by  the  various  degrees  of 
force  and  velocity,  and  the  orders  of  fuccefiion 
in  which  they  are  formed — is  it  likely,  then, 
that,  amidft  this  countlefs  and  almoft  inconcei- 
vable variety,  any  two  individuals  fhould  of- 
ten, or  naturally,  adopt  exactly  the  fame  com- 
bination, bring  their  mufcles  to  act:  in  the  fame 
order  of  fucceffion,  or  employ  them  with  the 
fame  force  and  velocity  in  uttering  found  or 
articulating  words  ?  I  mould  think  not.  Even 
that  mimicry  of  the  tone  and  voice,  which  ex- 
tends only  to  the  general  outlines  or  promi- 
nent characters,  is  very  rare,  and  would  feldom 
deceive  an  ordinary  ear,  if  prfcviouily  warned

that  fact  feems  to  be  afferted,  I  mould  rather  imagine  is

X  rom  the  preceding  obfervations  upon  lan- 
guage, the  following  inferences  may  naturally 
be  drawn :  That  the  language  of  fcience,  if 
meant  to  be  either  permanent  or  general,  mould 
be  diftin6r.  from  the  language  of  the  country  ;— 
that  it  mould  not  be  entrufted  to  the  manage- 
ment of  the  ear,  whofe  tafte  is  variable  ;  nor 
its  fate  committed  to  the  organs  of  voice,  which, 
varied  and  irregular  in  their  own  actions,  are 
at  all  times  under  its  influence ; — that  it  mould 
be  a  language  primarily  or  principally  addref- 
fed  to  the  eye,  which  has,  not  like  the  ear, 
the  fame  power  of  new-modelling  and  chan- 
ging its  objects ; — and   mould  be  a  language

conftrucled  on  purpofe,  or  a  written  language, 
whofe  vocal  archetype  is  already  dead,  and  no 
longer  capable  of  creating  difturbance  or  in- 
novation : — in  (hort,  a  language  as  much  as  pof- 
lible  placed  beyond  the  vortex  of  fafhion  and 
the  reach  of  change  ;  where  the  (trained  ana- 
logies of  fimile  and  metaphor,  or  other  forced 
and  unnatural  applications,  have  little  chance 
of  rendering  it  vague. 

Some  have  imagined  that  a  written  lan- 
guage, conftructed  on  purpofe,  would  be  pre- 
ferable to  any  of  our  dead  languages  \  but  in 
what  refpedt  is  not  ealily  demonstrated.  In  all 
languages  where  fciences  are  treated,  it  is  ac- 
knowledged that  there  are,  or  ought  to  be, 
two  kinds  of  terms,  perfectly  diitinct: ;  one  a- 
dapted  to  general  ufe,|and  the  other  divided  in- 
to many  fpecies  peculiarly  appropriated  to  the 
purpofes  of  fcience.  The  part  adapted  to  ge- 
neral ufe  cannot  poflibly  have  a  reference  to 
any  particular  fpecies  of  fcience,  as  every  fci- 
ence mult  have  a  feparate  language  of  its  own; 
nor  can  it  have  a  reference  to  the  fciences  at

large,  and  therefore  mud  be  equally  indiffe- 
rent to  all  of  them.  It  is  true  indeed,  if  a 
general  language,  artificially  conftrucled,  were 
generally  adopted,  and  generally  underftood, 
it  might  fave  the  trouble  and  prevent  the  er- 
rors arifing  from  tranflation  ;  but  not  more 
fo  than  a  dead  language,  generally  adopted 
with  a  fimilar  view.  At  the  fame  time,  nei- 
ther one  nor  the  other  would  compenfate  for 
the  eafe  with  which  we  write  in  our  own 
language  ;  nor  for  the  precilion,  clearnefs,  and 
readinefs  with  which  we  perceive  the  force  of 
its  expreffion.  It  is  therefore  fufficient  in 
every  fcience  that  its  technical  terms  mould  be 
kept  diftind  from  the  language  which  is  fpo- 
ken ;  that  all  its  terms  fhould  have  a  certain  and 
determinate  meaning,  fhould  remain  unalter- 
ed in  every  tranflation,  and  mould  be  the  fame 
in  every  country  where  the  fcience  is  either 
known  or  cultivated.  With  refpecl  to  the 
origin  of  fuch  terms,  it  will  be  indifferent  whe- 
ther they  be  mere  upftarts  of  yefterday,  or  li- 
neal defcendants  from  the  ancient  families  of

Pagan  antiquity;  only  if  defcended  in  that 
way,  they  muft  not  fhine  by  a  borrowed  light, 
they  muft  ftand  or  fall  by  their  own  merit ; 
and  mould  they  be  now  in  a  different  capa- 
city from  what  they  were  formerly,  their  ori- 
ginal confequence  mould  entirely  bea  forgot- 
ten. Every  thing  in  fcience  ought  to  be 
real,  ingenuous,  and  open  ;  and  every  expref- 
lion  that  indicates  duplicity  or  equivocation, 
refervation,  wavering,  or  inconfiftency,  is  a  re- 
proach to  it. 

The  Greek  and  Latin,  the  two  dead  langua- 
ges moft  generally  known,  particularly  in  Eu- 
rope, furniih  moft  of  the  terms  of  our  prefent 
nomenclatures.  The  only  inconvenience  of 
thefe  terms  is  that,  often  being  ufed  in  a  fecon- 
dary  fenfe,  which  has  a  faint  or  diftant  analo- 
gy to  the  original,  they  are  very  apt  to  convey 
double  meanings ;  and  thus  create  a  confufion 
of  ideas  in  thofe  acquainted  with  their  prima- 
ry import.  All,  however,  are  not  of  this  de- 
fcription.  Many  of  them  now  have  the  fame 
effecl  as  arbitrary  names  ;  and  as  for  the  reft, 

wLen 


90  TECHNICAL  LANGUAGE 

when  fome  time  accuftomed  to  their  fecondary 
meaning,  we  gradually  forget  that  they  ever 
had  another. 

In  choofing  terms,  the  tafte,  doubtlefs,  may 
be  confulted ;  though  on  no  pretext  mould 
it  be  allowed  to  direct  the  judgment,  and  de- 
cide on  matters  of  convenience  and  utility. 
In  the  choice  and  invention  of  new  words,  fo 
far  as  refpects  the  length  and  the  found,  let  it 
difplay  its  whole  ingenuity  ;  but  where  a  no- 
menclature is  already  eftablifhed,  it  ought  to 
give  place  to  a  higher  authority.  In  anatomy, 
for  inftanee,  it  has  no  right  from  either  its  na- 
tural or  acquired  feelings  to  determine  the  quef- 
tions,  What  are  the  terms  that  ought  to  be  re- 
jected ?  or,  Whether  thofe  which  we  mean  to 
retain  ought  to  be  derived  all  from  the  Greek, 
all  from  the  Latin,  or  partly  from  both  ?  It  is 
one  thing  to  form  a  new  fyftem  of  laws  for  an 
infant  colony,  and  another  to  make  a  general 
reform  in  an  ancient  government. 

If  the  words  of  only  one  of  the  languages 
were  to  be  retained,  we  indeed  might  produce 

a

a  fort  of  uniformity  to  pleafe  the  grammarian  ; 
but  what  is  that  to  the  anatomift  ?  Will  the 
dictates  of  reafon  or  of  common  fenfe  ever  in- 
duce him  to  facrifice  his  convenience  and  in- 
tereft  for  fuch  an  object  ?  and  if  he  did,  what 
idea  muft  be  formed  of  the  mind  that  would 
leave  ferious  and  important  fludies  to  amufe 
itfelf  in  gazing  at  the  fhadows  of  antiquated 
words  ?  for  nothing  befides  the  mere  fhadows 
of  ancient  vocables  are  in  general  to  be  ex- 
pected among  the  terms  of  our  nomenclatures. 
They  may  have  fomething  of  a  learned  found, 
but  they  cannot  poilibly  retain  much  of  a  claf- 
ilcal  fenfe,  when  applied  to  objects  of  which  the 
ancients  were  entirely  ignorant. 

The  Greek  and  Latin  are  both  fan&ioned 
in  our  prefent  nomenclature  :  to  difpoffefs  one 
of  them  entirely,  would  necefTarily  cccafion  the 
introduction  of  many  new  terms  and  the  rejec- 
tion of  many  old  ones.  Suppofefor  a  moment 
that  the  change  has  taken  place,  and  the  ques- 
tion put,  What  improvements  have  we  added 
to  fcience,  or  what  advantages  have  we  acqui-

red  by  it  ?  Why  the  pleafure,  and  nothing  but 
the  pleafure,  of  feeing  the  terms  of  our  nomen- 
clature all  derived  from  the  fame  language. 
Our  tafte  may  be  gratified,  and  we  probably 
may  feel  fomething  like  his  fatisfadtion  who, 
regardlefs  of  the  other  qualities  of  his  fervants, 
is  anxious  only  to  have  them  all  from  the  fame 
country.  His  favourite  object,  fuch  as  it  is, 
may  be  one  that  he  would  not  eafily  renounce ; 
but  can  it  be  the  object  of  a  wife  man  ?  And 
when  he  has  got  it,  is  it  his  reafon  or  his  hu- 
mour that  is  gratified  ? 

This  fpecies  of  motive,  and  I  know  no 
better  for  adhering  flrictly  to  one  of  the  lan- 
guages of  our  prefent  nomenclature,  can  have 
little  influence  on  a  cool  reflecting  philofophic 
mind.  He  who  confiders  the  fluctuating  na- 
ture of  vocal  language,  will  not  pay  a  high  de- 
ference to  words,  either  on  account  of  the  age 
or  the  country  in  which  they  have  flourifhed  ; 
and  he  who  is  eager  in  the  purfuits  of  fcience, 
will  feldom  enquire  whether  they  have  come 
from  Athens  or  Rome :  he  will  cheerfully  wel- 
come

come  the  natives  of  both,  provided  that,  by 
their  united  affiflance,  he  is  brought  more 
fafely  or  more  expeditioufly  to  the  end  of  his 
journey.  I  fhould  therefore  be  inclined,  not- 
withftanding  the  opprobrium  attached  by  fome 
to  certain  connections  and  intermarriages  among 
harmlefs  vocables,  not  to  reject  the  co-operation 
of  the  two  languages  in  any  form,  where  ex- 
perience  mows  it  to  be  convenient,  ufeful,  or 
neceflary.

THE  TECHNICAL   LANGUAGE  OF  ANATOMY, 
HOW  TO  BE  IMPROVED. 


Jl  rom  the  above  preliminary  difcuffions  upon 
languages  in  general  and  nomenclatures,  we 
proceed  now  to  the  more  immediate  fubjedl  of 
the  Effay,  the  Nomenclature  of  Anatomy. 
In  this  nomenclature  we  mean  to  propofe  fome 
alteration? ;  but  as  every  alteration  is  not  an 
improvement,  it  becomes  a  fair  and  reafonable 
queftion,  What  is  to  be  their  nature  and  ob- 
ject, ai:d  what  advantages  are  likely  to  arife 
from  the  execution  of  fuch  a  defign  ? 

On  the  cooler!  and  mod  impartial  inquiry, 
it  appears  that  many  of  the  prefent  terms  con- 
vey falfe  or  erroneous  ideas; — -that  many  are 
fuperfluous,  and  of  the  fuperfluous  many  fuper- 

numerarv : 


or  an  at o  mt,  &c.  i  95 

numerary  ;i — that  many  allude  to  antiquated 
names,  which  are  but  feldom  or  no  longer 
ufed  ;— that  many  have  a  vague  indeterminate 
meaning,  and  are  cohfequently  ufed  in  various 
fenfes  \ — and  that  feveral  parts  have  received 
names,  while  thofe  wholes  of  which  they  are 
parts  have  received  none.  From  this  view  it 
has  been  fuppofed,  that  we-re  the  falfehoods 
and  errors  corrected,  the  fuperfluities  retrench- 
ed, the  troublefome  and  unneceflary  allufions 
dropt,  the  ambiguities  removed,  and  the  feve- 
ral deficiencies  properly  fupplied,  the  nomen- 
clature would  not  only  be  improved,  but  the 
ftudy  of  anatomy  greatly  facilitated. 

As  confufed  expreffion  is  too  often  a  natural 
confequence  of  confufed  ideas,  fo  ambiguities, 
in  the  language  of  fcience,  may  often  be  tra- 
ced to  the  want  of  a  clear  and  diftinct  arrange- 
ment. And  mould  it  afterwards  be  found  that 
feveral  vague  terms  in  anatomy  derive  their 
origin  from  this  fource,  a  new  and  improved 
claffification,  where  the  circumflances  require 
it,  will  alfo,  it  is  thought,  be  attended  with 
advantage.

It  was  certainly  the  clear  arrangement  of 
Linnaeus,  comparatively  fpeaking,  that  ena- 
bled him  to  give  fuch  precifion  to  his  Ian* 
guage  ;  and  that  precifion  has  greatly  contri- 
buted to  promote  the  fcience,  as  being  a  fure 
and  unerring  guide  to  the  different  objects 
which  it  prefented ;  objects  which,  in  confe- 
quence  of  his  arrangement,  have  received  a  de- 
finite and  fixed  ftation,  where  the  ftudious  in- 
quirer may  readily  find  it.  For  this  purpofe 
Linnaeus  arranged  them  into  different  groups, 
which  he  called  claffes ;  fubdividing  thefe 
claffes  into  orders,  the  orders  into  genera,  and 
the  genera  into  fpecies  ;  always  taking  care 
that  thefe  belonging  to  the  fame  clafs  fhould 
have  one  or  more  properties  in  common,  thofe 
belonging  to  the  fame  order  two  or  more,  thofe 
of  the  fame  genus  three  or  more,  and  thofe  of 
the  fame  fpecies  four  or  more.  To  each  of 
thefe  groups,  which  were  comparatively  few 
in  number,  he  gave  names,  annexing  a  fhort 
defcription  of  the  characters  by  which  they 
were  diftinguifhed.     It  was  by  adopting  a  fi- 

milar 


OF  ANATOMY,  &C  97 

milar  methoctthat  Lavoifier  improved  the  fci- 
ence  of  chemiftry ;  and  therefore  it  is  furely  an 
error  to  fuppofe  that  thefe  two  celebrated  men 
confined  themfelves  merely  to  changes  upon 
language.  Their  merits  were  of  a  fuperior 
kind.  A  change  of  nomenclature,  had  that 
been  all,  would,  by  introducing  a  new  fet  of 
terms,  have  only  retarded  the  progrefs  of  fci- 
ence.  Their  ciaffification  was  that  which  ad- 
vanced it :  it  collected  the  fcattered  materials 
together,  exhibited  the  wThole  in  a  ftate  of  con- 
nection, brought  them  within  the  fphere  of 
our  vifion,  and  placed  them  at  once  under  the 
eye  in  a  proper  light ;  while  their  nomencla- 
tures ferved  as  mediums  through  w7hich  they 
were  feen  more  clearly  and  distinctly  ;  or  ra- 
ther were  a  kind  of  fymbolical  pictures,  repre- 
fenting  to  the  mind  the  ftate  of  the  fciences, 
with  the  changes  or  improvements  that  had 
been  introduced. 

From  viewing  the  rapid  progrefs  of  chemiftry 

that  followed  immediately  on  the  change  of  its 

language,  fome  have  been  led  to  confider  the  two 

G  as 


98  TECHNICAL  LANGUAGE 

as  caufe  and  effect: ;  overlooking  thofe  impor- 
tant difcoveries  to  which  the  fcience  was  prin- 
cipally indebted  for  its  advancement,  and  even 
miftaking  the  merits  of  Lavoiiier  in  thofe  la- 
bours for  which  he  is  celebrated.  The  genius 
of  this  illuftrious  perfon  was  attracted  chiefly 
by  the  great  and  the  fublime  :  he  felt  little 
pleafure  in  partial  remarks,  or  in  noting  mi- 
nutely the  infulated  phenomena  that  take  place 
in  the  dark  corners  of  a  laboratory.  As  his 
mind  led  him  to  general  obfervations,  and  to 
be  delighted  with  extenlive  views,  it  embraced 
in  its  wide  comprehenfive  grafp  a  variety  of 
objects,  faw  at  a  glance  their  agreements  and 
difcordancies,  arranged  them  in  a  clear  and 
luminous  order,  and  thence  drew  concluiions 
that  fhot  light  through  every  department  of 
chemical  fcience  hidden  or  remote. 

From  what  he  had  obferved,  he  believed 
that  empyreal  or  vital  air  was  the  caufe  of 
acidity  in  all  bodies,  and  he  named  it  oxygen  ; 
he  faw  that  oxygen  entered  into  various  com- 
pounds with  metals,  and  gave  to  thefe  com- 
pounds 


OF  ANATOMY,  &C.  99 

potinds  the  title  of  oxides.  Directing  his  atten- 
tion to  the  acids  which  it  forms,  he  found  them 
more  numerous  than  had  been  fuppofed  ;  di- 
flinguifhed  each  by  a  certain  change  on  the 
name  of  the  fubftanCe  from  which  it  was  ob- 
tained \  faw  many  of  them  widely  diffufed  over 
Nature,  and  everywhere  entering  into  various 
compounds  with  the  feveral  metals,  alkalies, 
and  earths— to  thefe  compounds  he  gave  no 
general  or  common  name  denoting  a  elafs,  like 
the  word  oxide ;  but  according  to  the  acid 
which  they  contained,  arranged  them  into  ful- 
phats,  nitrats,  muriats,  and  fo  on.  In  thefe 
labours  his  claffification  and  fublime  difcove- 
ries  were  of  more  real  eonfequence  to  chemif* 
try  than  his  nomenclature  ;  and  yet  his  no- 
menclature was  not  without  its  merits :  It 
i 

ferved  to  communicate  the  grand  ideas  which 
he  had  formed ;  and  expreiTed  them  with  a 
clearnefs,  concifenefs,  and  flmplicity,  that  had 
not  till  then  been  witnefTed  in  the  fcience  :  it 
was  happy  particularly  in  the  names  of  com- 
pounds, as  fulphat,  carbonat,  or  muriat  of  fo- 
G  2  da; 


XOO  TECHNICAL  LANGUAGE 

da  \  denoting  at  once  the  nature  of  the  fab- 
fiances  of  which  they  were  compofed :  and 
even  went  farther,  attempting  occaiionally,  as 
in  the  words  oxygen  and  hydrogen,  to  convey 
a  defcription  in  the  appellations  of  fimple  fub- 
ftances. 

The  defcriptive  terms  in  this  nomenclature 
have  been  much  admired,  and  many  have  wim- 
ed  that  the  like  were  introduced  into  fome  of 
the  other  languages  of  fcience.  With  a  view 
to  this  improvement,  many  of  the  prefent  terms 
of  anatomy  have  been  condemned  for  not  ex* 
preffing  fome  quality  or  circumftance  of  the 
objects  which  they  fignify,  and  others, /con- 
taining a  kind  of  mort  definition  or  defcrip- 
tion, been  fubftituted  for  them.  As  it  may 
be  both  withed  and  expected  that  the  new 
terms  brought  into  anatomy  were  all  of  this 
fort,  a  previous  inquiry  into  their  nature, 
ufes,  and  peculiar  advantages,  will  not  be  im- 
proper* The  French  have  lately  adopted  fuch 
terms  in  their  modern  calendar  :  The  words

fhow  the  fpecies  of  weather  which  prevails  at 
certain  periods  of  the  year.  Let  us  fee  the  im- 
provement :  The  weather  being  variable  even 
in  France,  and  the  rain  and  fnow  not  hap- 
pening to  fall  always  at  the  time  foretold  in 
the  calendar,  thefe  terms  become  fo  many  ly- 
ing predictions ;  and  in  countries  where  the 
feafons  and  climate  are  different,  are  an  abfurd 
unintelligible  jargon.  But  what  are  the  defcrip- 
tive  terms  in  anatomy  ?  Not  a  great  deal  bet- 
ter. Many  of  thefe,  as  fphenoides,  ethmoides, 
aftragalus,  cuboides,  which  are  founded  on  vague 
and  remote  analogies,  fcarcely  convey  the  moft 
diftant  idea  of  the  forms  which  they  were  meant

To  anfwer  thefe  queftions,  it  may  be  obferved,

Nor  is  it  perhaps  difficult  to  explain  how 
many  words,  from  being  defcriptive,  fhould 
thus  become  arbitrary.  Suppofe  that  five  dif- 
ferent perfons  faw  each  a  different  fet  of  expe- 
riments on  one  of  the  gafes  whofe  name  was 
unknown,  and  that  each  mould  afterwards  ex- 
plain to  the  reft  what  he  had  feen  ;  it  would 
be  impoffible  for  them  to  know  that  they  all 
were  defcribing  but  different  phenomena  of 
the  fame  gas. 

Suppofe,  again,  that  during  the  experiments 
each  had  been  told  that  the  gas  was  oxy- 
gen, the  word  oxygen  would  have  with  each 
a  different  meaning ;  and  mould  it  be  after- 
wards pronounced  in  their  prefence,  would 
ferve  as  a  fignal  of  general  rendezvous  for  all 
their  ideas  on  the  nature  of  the  gas.  Upon  hear- 
ing the  word  oxygen  pronounced,  each  would 
recal  and  marfhal  in  his  memory  his  quota  of 
phenomena ;  every  quota  would  differ  from 
another,  but  every  one  of  them  would  belong 
to  oxygen  ;  and  they  now  would  perceive,  up- 
on each  relating  what  he  had  feen,  that  the 
properties  and  phenomena  of  this  fubftance 

were 


IC6  TECHNICAL  LANGUAGE 

were  more  numerous  than  what  any  of  them 
had  previoufly  imagined. 

Suppofe  farther,  that  all  its  various  pro- 
perties and  phenomena  are  known  to  the 
five,  and  that  each  now  were  deli  red  to  men- 
tion a  few  of  the  moil  obvious  and  chara&e- 
riftic,  it  is  probable  that  each,  if  any  room 
were  left  for  fele&ion,  would  mention  thofe 
which  had  made  the  deepeft  and  moft  lively 
impreffion  on  his  own  mind;  an  impreffion 
which  evidently  would  depend  upon  taile,  fan- 
cy, and  judgment,  and  a  variety  of  other  cir- 
cumftances,  not  ealily  enumerated.  Allowing, 
however,  the  fele&ion  to  be  made,  and  that 
each  were  required  to  give  to  the  gas  a  de- 
fcriptive  name  alluding  to  the  property  which 
he  conceived  the  moft  obvious  and  chara&e- 
riftic,  every  name  would  differ  from  another, 
all  would  be  limited  in  their  fignification,  and 
each  pointing  out  a  particular  property  exclu- 
five  of  others  ;  none  of  them  would,  while  in 
that  capacity,  ferve  as  a  fignal  of  general  ren- 
dezvous for  our  ideas  on  the  fubjecl  of  oxygen. 

A 


OF  ANATOMY,  &C.  IO7 

A  defcriptive  name  is  therefore  inferior,  in 
certain  cafes,  to  an  arbitrary  name.  The  for- 
mer recals  particular  ideas,  the  latter  makes 
no  diftin&ion  whatever,  but  fummons  every 
idea  on  the  fubject  ;  and  when  they  are  all 
collected  together,  arranged,  and  examined, 
prefents  us  with  a  general  view  of  the  whole. 
From  this  it  appears  that  the  arbitrary  name 
is  the  fymbol  of  a  clafs,  genus,  or  fpecies, 
which  every  one  defines  or  defcribes  accord- 
ing to  the  notions  which  he  has  collected 
from  among  the  individuals ;  and  that  the 
defcriptive  is  the  fymbol  only  of  a  certain 
character  belonging  to  this  clafs,  genus,  or 
fpecies,  which,  when  it  difcriminates  con- 
cifely  and  accurately,  is  convenient  and  ufe- 
ful,  but  otherwife  obtrudes  the  author's  con- 
ceit, folicits  our  attention  to  fome  particular 
fancy  or  whim,  and  prefumes  to  recommend 
it  as  the  guide  or  the  object  of  our  refearches. 

If  oxygen,  hydrogen,  and  azot,  exhibit  a 
variety  of  different  characters  befides  thofe 
implied  in  their  names,  every  man,  as  well 

as 


I©8  TECHNICAL  LANGUAGE 

as  Lavoifier,  will  feel  he  has  a  right  to  fix 
on  his  own  marks  of  diftin&ion,  and  will  na- 
turally prefer  his  own  to  another's :  fo  that  fuch 
words  muft  at  lad  be  ufed  in  an  arbitrary  fenfe, 
or  be  laid  afide;  for  no  man  in  a  matter  of  in- 
difference will  fubmit  to  the  tyranny  of  being 
unneceffarily  reftridted  in  his  choice.  A  de- 
fcriptive  word  is  fomewhat  like  a  picture:  Now 
if  a  picture  be  meant  for  a  likenefs,  it  mould 
either  exhibit  every  character  of  the  original, 
or  at  lead  thofe  that  are  unavoidably  obvious 
to  all ;  for  different  pecfons  will  diflinguifh  an 
object  by  different  marks  and  different  por- 
tions, and  thofe  will  never  difcover  the  refenj- 
blance  who  fee  not  the  features  by  which  they 
were  wont  to  know  the  original;  though  others, 
accuftomed  to  know  it  by  the  traits  which  the 
painter  has  copied,  may  be  furprifed  at  their 
want  of  penetration,  and  pronounce  the  figure 
an  admirable  likenefs. 

Indeed  Lavoifier  has  not  extended  his  de- 
scriptive language  through  the  whole  nomen- 
clature ;  he  has  confined  it  to  thofe  fubftan- 

ces 


Or  ANATOMY,  &C  IO9 

ces  that  in  his  time  were  but  newly  difcovered, 
and  to  that  part  of  chemical  fcience  where  he 
found  it  necefTary,  for  the  fake  of  arrangement. 
Exclufive  of  a  few  of  the  fimple  fubftances,  he 
has  confined  it  to  the  combinations  of  oxygen 
with  metals,  and  the  combinations  of  acids  with 
rnetals,  alkalies,  and  earths.  His  partiality  for 
thefe  acids,  the  caufe  of  whofe  diftinguifhing 
property  he  found  to  be  oxygen,  has  made  him 
divide  the  lafl  combinations  into  fulphats,  ni- 
trats,  muriats,  and  fo  on,  as  if  the  acids  were 
fo  many  fpecies  or  modifications  of  the  different 
metals,  alkalies,  and  earths.  Thus  under  calx, 
which  fignifies  lime,  we  find  the  divifions  to 
be  fulphats,  nitrats,  muriats,  acetats,  &c. ;  in- 
Head  of  calx  vitriolata,  nitrata,  muriata,  ace- 
tata  ;  the  more  fimple  and  natural  divifions  of 
the  ingenious  ever  memorable  Bergman.  Yet 
Lavoifier's  method  has  alfo  its  advantages ;  and 
at  this  time  of  day,  where  no  real  inconvenien- 
cy  is  felt,  any  alteration  could  only  proceed 
from  mifguided  ignorance,  or  a  fpecies  of  ma- 
nia for  nomenclaturing.

claflifieation ;  and  the  clufters  or  groups  into 
which  he  has  divided  natural  objects  were^  fo 
far  at  leaft  as  arrangement  is  concerned,  entirely 
a  work  of  his  own  creation*  Thefe  neceiTarily 
required  new  names ;  and  thefe  names  are  fome- 
times  defcriptive,  expreffing  the  characters  by 
which  the  clufters  or  groups  are  diftinguifhed  5 
at  the  fame  time  he  gave  new  names  to  the  in- 
dividual objects  which  had  none ;  fixed  upon 
one  particular  name  where  there  were  many  5 
rejected  thofe  which  had  double  meanings  5

ed to  miflead,  retard,  or  obftruct  the  ftudious

JuLaving  feen  how  much  the  effential  merits 
of  every  nomenclature  muft  depend  on  the  pre- 
vious arrangement  of  its  objects,  it  may  here 
be  obferved,  for  the  fake  of  order,  that  the  ani- 
mal fy  (terns,  for  which  we  principally  intend  this 
nomenclature,  are  compofed  of  a  great  variety  of 
organs,  differing  in  appearance,  flructare,  and

rent  kinds  of  fecreting  organs,  which  are  call-

which  envelope  them ;  and  a  common  cover- 
ing of  different  layers,  called  the  Integuments, 
which  furrounds  the  whole. 

As  in  a  fyftem  fo  complex  and  varied,  an  accu- 
rate knowledge  of  fituation  and  pofkion  mull 
ever  be  a  matter  of  the  firft  importance,  anato- 
mifts  have  long  been  in  the  practice  of  confider- 
ing  every  organ  as  poffeffing  eight  different  af- 
rjecls,  which  point  in  as  many  different  direc- 
tions ;  upwards,  downwards,  backwards,  for-

writer  borrowed  from  the  common  language 
of  the  country,  where  they  are  ufed  in  a  vague 
fenfe  both  in  their  literal  and  figurative  accep- 
tation. From  the  various  directions,  lituations, 
and  pofitions  to  which  they  are  applied,  not 
being  accurately  clafYed  and  defined,  they  are 
carelefsly  transferred,  on  the  flighted  analogy, 
from  one  to  another,  with  fcarcely  any  fort  of 
difcrimination.    They  may  indeed  be  occafion- 
ally  defined ;  but,  in  general,  what  iignifies  a 
definition?  No  definition  can  eafily  break  the 
ilrong  aifociation  between  them  and  their  ideas ; 
an  aifociation  which  has  been  gradually  forming 
for  years,  and  which  continues  to  be  fupported 
daily  by  the  public  fancftion.  Their  ambiguous 
meaning  will  be  conftantly  recurring  whenever 
they  are  uttered  ;  and  while  that  recurs,  or  is 
apt  to  recur,  we  may  venture  to  fay  that  they 
cannot  with  propriety  be  retained  in  anatomy. 
On  this  fingle  objection  alone  they  ought  to  be 
rejected ;  but  unfortunately  there  are  others 
which  are  lefs  furmoun table,  and  which  will 
appear  on  a  more  particular  inveftigation, 

SUPERIOR

Superior  and  Inferior. 

These  terms,  in  their  primary  fenfe,  con- 
tain an  allufion  to  the  fituation  of  different  ob- 
jects, as  they  ftand  with  refpect  to  the  heavens 
and  the  earth  ;  and  that  they  may  regularly 
carry  this  allufion  to  the  fame  parts  in  the  lan- 
guage of  anatomy,  the  body  is  fuppofed  always 
to  remain  in  the  fame  pofition.  The  parties 
lar  pofition  which  anatomifts  have  chofen  is

natural for  the  lower  animals,  we  call  in  the 
affiftance  of  fancy*  and  in  fpite  of  the  fenfes 
fet  them  bolt  upright  on  the  point  of  their 
tail,  or  their  hind  legs ;  or,  difregarding  the 
primary  fenfe  of  fuperior  and  inferior,  we  ap- 
ply them,  without  any  reference  to  afpect,  to 
parts  that  correfpond  in  form,  ufe,  or  fyflematic 
connection* 


H  2  Anterior 


Il6  TERMS  RELATING  T6 

Anterior  and  Posterior, 

Like  thelaft,  fuppofe  the  ereft  pofition,  and 
denote  the  parts  before  and  behind.  In  the 
lower  animals^  when  allowed  to  remain  in  their  - 
natural  attitude,  they  fignify  the  parts  below 
and  above  ;  and  thus  ufed  as  a  fort  of  arbitrary 
terms,  exprefs  correfponding  parts  of  the  fyf- 
tem. 

External  and  Internal 

Are  more  vague  than  the  preceding.  The 
parts  of  generation  are  external  or  internal  with 
refpecl:  to  the  general  furface  of  the  body. 

The  parts  of  an  organ  are  external  or  inter- 
nal with  refpecl:  to  the  furface  of  the  organ 
itfelf.      : 

The  angles  of  the  eye  are  external  and  in- 
ternal with  refpecl;  to  the  lateral  parts  of  the 
face  and  the  middle  fuperficial  line  that  divides 
them. 

The 


POSITION  AND  ASPECT.  II7 

The  parts  of  the  leg  are  external  and  inter- 
nal with  refpect  to  its  furface,  or  with  refpect. 
to  the  nearnefs  and  diftance  of  the  line  that 
paffes  through  the  axis  of  the  body.  Thus  all 
parts  of  the  leg  are  external  if  fuperficial;  and 
all  parts  likewife  external,  however  deep,  if 
they  happen  to  be  fituated  in  what  we  exprefs 
by  the  outer  fide. 

While  the  arm  is  in  a  (late  of  extenfion,  and 
parallel  to  the  trunk,  the  fide  next  the  trunk  is 
internal ;  but  as  the  radius  rolls  on  its  axis,  it 
becomes  a  queftion,  which  is  the  fide  next  to  the 
trunk?  The  thumb,  the  palm,  and  the  little  fin- 
ger, may  in  fucceffion  all  afiume  thatfituation. 
Accordingly  thofe  who  defcribe  the  hand  in  a 
(late  of  pronation,  make  the  thumb  internal ; 
thofe  who  defcribe  it  in  a  Rate  of  fupination,  make 
the  finger  external ;  while  Albinus,  preferring 
the  middle  pofition,  makes  the  palm  internal. 
Thus  each  of  thefe  words  in  the  upper  extre- 
mity, adding  the  fenfe  fuperficial  and  deep, 
have  no  lefs  than  four  different  meanings;  and 
three  of  thefe  extended  to  the  bones,  mufcles,

he  fpeaks  of  their  origin  ;  and  another,  where 
he  talks  of  their  infertion. 


Right  and  Left 

Can  never  be  applied  with  any  propriety  to 
parts  of  the  extremities.  As  the  right  fide  of 
the  one  leg  or  arm  correfponds  in  form,  ftruc- 
ture,  and  functions  to  what  is  the  left  fide  of 
the  other  ;  they  are  therefore  applied  to  the 
extremities  only  as  wholes,  and  to  parts  of  the 
vifcera  in  the  great  venters,  where  they  fome- 
times  attempt  to  denote  fituation  with  little 
fuccefs,  particularly  when  applied  to  the  car*

crum. In  fyrlematic  connection  thefe  occupy 
correfponding  regions  in  all  animals  in  which 
they  are  found.  Inftead  of  the  words  Superior 
and  Inferior,  I  would  therefore  propofe  At- 
lantal  and  Sacral. 

The  bread  and  the  back  exprefs  likewife 
correfponding  regions  in  all  animals ;  and  there- 
fore, inftead  of  Anterior  and  Pofierior,  we  might 
adopt  Sternal  and  Dorsal. 

When  External  and  Internal  fignify  what  is 
fuperficial  and  deep,  we  might,  in  their  place, 
employ  the  words  Dermal  and  Central,  de- 
noting what  points  to  the  fkin  and  what  to  the 
centre :  or  if  we  happen  to  be  fpeaking  of  an  or- 
gan, Peripheral  and  Gen  tral  ;  the  term  Peri- 
pheral 


POSITION  AND  ASPECT.  121 

pheral  being  derived  from   the  Greek   word 
that  fignifies  "  circumference." 

When  they  lignify  the  fide  and  middle  of  a 
furface,  fuppofe  a  plane,  to  pafs  along  the  mid- 
dle of  the  neck,  the  mediaftinum,  and  linea  alba, 
and  to  dividing  the  neck  and  the  trunk  into 
fimilar  halves  from  the  fternum  to  the  dorfum, 
and  let  this  plane  be  denominated  Mesion  ; 
Lateral  and  Mesial  will  in  fuch  a  cafe  con- 
vey the  meaning  of  external  and  internal;  and 
in  many  other  cafes,  as  we  mall  afterwards  fee 
by  examples,  be  extremely  ufeful  in  exprefiing 
both  fituation  and  direction. 

The  peculiar  meanings  of  External  and  In- 
ternal, as  they  are  applied  to  the  extremities, 
will  be  better  referred  to  their  proper  place. 

As  for  the  lateral  parts  of  the  trunk,  Right 
and  Left  might  (till  denote  thefe  ;  although, 
for  the  reafons  already  affigned  in  the  general, 
obfervations,  Dextral  and  Sinistral  might 
perhaps  be  preferable  ;  or  mould  there  be  no 
occafion  fcr  diftinction,  as  may  fometimes  hap- 
pen, the  word  Lateral  may  ferve  for  both. 

It 


122  NEW  TERMS  RELATING  TO 

It  has  already  been  noticed,  that  it  is  chief- 
ly in  defcribing  the  heart  they  are  apt  to  con- 
vey an  ambiguous  meaning,  and  occafion  trou- 
ble to  the  anatomifl ;  for  what  are  called  the 
right  and  left  ventricles  are  ftriclly  fpeaking 
neither  right  nor  left ;  and  thofe  who  have 
chofen  to  call  them  rather  anterior  and  pojle- 
rior  have  employed  terms  equally  vague;  and 
more  erroneous  if  they  be  extended  to  compa- 
rative anatomy.  To  avoid  the  inaccuracies 
which  muft  therefore  arife  from  the  ufe  of  fuch 
language,  it  mould  be  remarked,  that  the  vaf- 
cular  fyftem  in  all  the  nobler  fpecies  of  animals 
may  be  divided  into  two  parts,  each  confifting 
of  veins  and  arteries.  The  one  for  conveying 
blood  from  the  lungs  to  the  fyftem  at  large, 
and  the  other  for  conveying  it  again  from  the 
fyftem  back  to  the  lungs.  Let  the  veifels  which 
convey  it  from  the  lungs  to  the  fyftem  be  call- 
ed the  Systemic,  and  thofe  which  convey  it 
from  the  fyftem  to  the  lungs  be  named  the 
Pulmonic,  and  all  ambiguity  will  be  avoided. 
Thus  the  pulmonary  veins,  the  left  finus,  au- 
ricle, 


POSITION  AND  ASPECT.  I23 

ricle,  and  ventricle,  with  the  aorta  and  all 
its  branches,  will  bejyjiemicj  while  the  bron- 
chial veins,  the  veins  of  the  head,  heart,  trunk, 
and  extremities,  the  right  finus,  auricle,  and 
ventricle,  with  the  pulmonary  artery  and  all 
its  branches,  will  be  diftinguifhed  by  the  epi^ 
thet  pulmonic ;  and  if  it  be  neceffary  to  mark 
their  fituation  with  refpect  to  the  trunk,  or  to 
one  another  in  this  or  that  fpecies  of  animal, 
the  terms  already  ufed  for  the  trunk,  as  atten- 
tat, facral,  Jlernal,  dorfal,  dermal,  central,  dex- 
iral^Jlnijlral,  lateral,  and  mefial,  may  conveni- 
ently be  ufed  for  that  purpofe. 

Befides  removing  much  ambiguity,  another 
advantage  that  naturally  arifes  from  this  change 
in  the  nomenclature  is,  that  inftead  of  being 
obliged  to  enumerate  the  vefTels  in  which  the 
purpk  and  in  which  the  vermilion  blood  is 
contained,  we  may  fay  at  once  that  the  purple 
is  contained  in  all  the  pulmonic  vefTels,  and  the 
vermilion  in  all  the  fyflemic,  whether  veins  or 
arteries  \  that  thofe  animals  which  have  but 
pne  auricle  and  ventricle  have  no  vena  pulmo- 
nic 


124  NEW  TERMS  RELATING  TO 

nic  fyftem,  or  veins  which  carry  blood  to  their 
lungs  5  that  their  pulmonary  veffels,  in  fome 
meafure,  correfpond  in  function  to  our  bron- 
chials ;  and  that  their  blood,  undergoing  a 
change  from  the  action  of  the  air,  is  entirely 
confined  to  fyftemic  yeins. 


Terms  for  the  Aspects  of  the 
Extremities. 

In  defcribing  the  two  kinds  of  extremities, 
we  may  naturally  diftinguifh  them  by  epithets 
borrowed  from  the  regions  of  the  trunk  with 
which  they  are  connected,  calling  the  Superior, 
Atlantal,  and  the  Inferior^  Sacral  extre- 
mities. 

In  mentioning  the  ends  of  thefe  extremi- 
ties, or  the  ends  of  the  bones  of  which  they 
are  compofed,  we  may,  with  a  reference  to  the 
courfe  or  direction  of  the  extremity,  denomi- 
nate the  end  which  is  neareft  to  the  trunk  the 
Proximal  end,  and  that  which  is  farthefl 
from  it  the  Distal.     Thefe  lad  terms  may  be 

ufed 


POSITION  AND  ASPECT.  |2j 

ufed  as  common  in  defcribing  both  kinds  of  ex- 
tremities, and  in  diftinguifhing  the  ends  of  the 
coccyx  and  its  different  vertebrae.  The  other 
terms  mull  be  appropriate  if  they  are  to  be 
borrowed  from  the  names  of  the  parts  which 
conftitute  the  two  fpecies,  of  organs. 


Terms  for  the  Atlantal  Extremities. 

In  thefe  extremities  we  may  ufe  the  terms 
Radial  and  Ulnar  to  fignify  the  two  lateral 
parts,  and  with  little  hefitation ;  as  thefe  terms 
have  already  been  adopted  by  the  accurate  Win- 
flow  and  other  anatomifts  of  great  eminence. 

To  the  other  two  fides  we  may  give  the  epi- 
thets Anconal  and  Thenal  :  The  word  anconal 
containing  an  allufion  to  that  projecting  point 
of  the  elbow  which  the  ancient  Athenians 
and  modern  anatomifls  have  called  olecranon; 
but  which  other  Greeks  denominated  an- 
con,  the  name  from  which  we  derive  the  epi- 
thet belonging  to  the  mufcles  called  anconei. 

The 


126  '   NEW  TERMS  RELATING  TO 

The  word  thenal  is  taken  from  thenar,  the 
Greek  name  for  the  palm  of  the  hand  :  but 
here  we  transfer  the  word  thenar  to  fig- 
nify  the  flexure  or  fide  of  the  elbow  oppofed 
to  the  ancon ;  allowing  the  word  void  to  remain, 
and  ft  ill  to  fignify  that  part  on  the  thenal  fide 
which  is  called  the  palm. 

The  afpects  therefore  of  each  atlantal  extre- 
mity, and  of  all  its  parts  from  the  fcapuia 
downwards,  will  be  Proximal  and  Distal, 
Dermal,  Central,  Ulnar,  and  Radial, 
Anconal  and  Thenal  ;  while  the  fcapuia,  - 
from  its  clofe  and  intimate  connection,  will 
have  its  afpe6ts  better  exprelfed  by  the  terms 
for  the  trunk. 


Terms  for  the  Sacral  Extremities, 

Those  parts  in  the  facral  extremities  which 
correfpond  in  their  general  form,  iituation,  and 
function,  with  the  ulna,  radius^  thenar,  and 
ancon  of  the  other  extremities,  are  the  tibia, 

fibula, 


POSITION  AND  ASPECT.  tVf 

fibula,  poples,  and  rotula  ;  and  therefore,  if  we 
here  preferve  the  analogy,  the  eight  afpects  of 
the  facral  extremities  will  be  Proximal  and 
Distal,  Dermal,  Central,  Tibial,  Fi- 
bular, Popliteal  and  Rotular  ;  allow- 
ing the  word  planta  to  remain,  as  we  did  vola, 
to  exprefs  the  fole  on  the  popliteal  fide  of  the 
foot ;  and  the  large  lateral  bones  of  the  pelvis 
to  borrow  their  terms,  as  does  the  fcapula,  from 
the  afpe&s  of  the  trunk. 

That  the  whole  of  thefe  terms  may  be  as 
generally  ufeful  as  poffible,  they  are  meant  to 
extend  in  their  application  as  far  as  thofe  for 
which  they  are  fubftituted.  Thus,  forinitance, 
in  the  Atlantal  extremity,  the  humerus,  and 
every  bone  to  the  points  of  the  fingers,  is  fup- 
pofed  to  have  a  proximal  and  di/lal,  a  peri- 
pheral and  central,  an  ulnar  and  radial,  a  the- 
nal  and  anconal  afpect ;  while  the  relative  fitu- 
ation  of  every  nerve,  mufcle,  and  artery,  is  to 
be  exprefTed  by  fome  one  or  other  of  thefe  epi- 
thets. To  illuilrate  my  meaning  by  an  exam- 
ple, I  {hall  take  the  interoffei  mufcles,   which 

are 


128  NEW  TERMS  RELATING  TO 

are  nothing  more  than  the  adductors  and  ab- 
ductors of  the  fingers.  Albinus  calls  thofe 
which  appear  on  both  fides  of  the  hand  the 
external,  and  thofe  which  appear  on  the  palms 
only,  the  internal.  Innes  retains  the  diftinction 
of  Albinus  with  refpect  to  the  origin  of  thefe 
mufcles ;  but  when  he  fpeaks  of  their  infertion, 
ufes  the  words  external  and  internal  in  a  diffe- 
rent fenfe  to  denote  the  lateral  parts  of  the  fin- 
gers. If  the  terms  here  propofed  were  adopt- 
ed, thefe  mufcles,  with  refpect  to  their  origins, 
would  be  all  either  anconal  or  thenal,  and  with 
refpecl  to  their  infertion  radial  or  ulnar.  Thus 
I  would  fay,  in  fpeaking  of  their  origins,  that 
the  two  belonging  to  the  forefinger  are  thenal; 
the  two  belonging  to  the  middle  finger,  anco- 
nal; thofe  belonging  to  the  ring  finger  and 
little  finger,  alternately,  thenal  and  anconal ; 
the  fewo  thenal  inferted  into  the  radial,  and  the 
two  anconal  into  the  ulnar  fides  of  thefe  fin- 
gers. I  have  only  to  add,  that  the  happy  ef- 
fects refulting  from  the  parrial  ufe  of  fuch  de- 
finite terms  in  Murray's  Defcription  of  the  Ar- 
teries, 


POSITION  AND  ASPECT.  I2<> 

teries,  muft  make  every  one  who  is  truly  and 
ferioufly  interefled  in  anatomy  extremely  anxi- 
ous to  fee  them  more  generally  employed. 

The  objections  ftarted  againft  thefe  terms,  if 
there  be  any,  will,  I  conceive,  be  probably 
fomewhat  of  the  following  nature. 

The  words  atlantal,  facral,  and  Jlernal,  al* 
lude  to  parts  that  are  not  to  be  found  in  thofe 
animals  which  have  no  vertebrae;  and,  befides* 
the  allufion  is  not  confined  to  the  part  itfelf, 
but  extended  to  a  fort  of  imaginary  plane  that 
is  fuppofed  to  be  in  their  vicinity.  The  an- 
fwer  is,  that  the  parts  occupy  correfponding 
regions  in  all  animals  in  which  they  are 
found ;  ihow  where  the  planes  are  to  be  drawn  \ 
and  that,  infiead  of  multiplying  terms,  and 
forming  new  and  diftincl:  nomenclatures  for  all 
the  diftincl  clafles  of  animals,  it  was  thought 
better,  where  no  ambiguity  was  to  be  dreaded, 
to  give  to  the  epithets  borrowed  from  thefe 
parts  a  fort  of  general  and  arbitrary  fenfe,  and 
transfer  them,  by  analogy,  to  all  the  corre- 
I  fponding 


I3O  NEW  TERMS  RELATING  TO 

fponding  regions  of  the  fyftem  in  every  fpecies. 

The  objection  ariling  to  the  anfwer  itfelf,  that 
thefe  terms,  taken  in  a  general  and  arbitrary 
fenfe,  can  no  longer  allude  to  the  parts  from 
which  they  are  borrowed,  is  eafily  removed  by 
caufing  a  change  in  the  termination,  to  fhow 
when  they  allude  to  the  part,  and  when  to  the 
afpecl. 

Similar  objections  may  likewife  be  made  to 
the  words  ulnar,  radial,  tibial,  fibular,  rotular, 
and  popliteal;  and  a  fimilar  anfwer  may  alfo 
be  given  :  though  this  may  be  further  faid  in 
their  favour,  that  they  have  been  adopted  by 
other  anatomifts,  particularly  Chauflier  ;  and 
if  their  ufe  here  be  extended,  it  was  to  avoid 
the  unneceffary  multiplication  of  terms,  and  to 
preferve,  as  much  as  poffible,  fimplicity,  unity, 
and  concifenefs  of  arrangement,  by  limiting 
the  number  of  general  afpedts  to  which  the 
fubordinate  ones  are  referred. 

The  meaning  of  the  words  anconal  and  the~ 
nal  is  likewife  different  from  their  primary 
meaning  \  but  the  language  from  which  they 

are 


POSITION  AND  ASPECT.  I3I 

ar*i  borrowed  is  dead,  and  the  primary  mean- 
ing will  have  little  chance  of  being  fuggeiled, 
along  with  that  in  which  they  are  employed, 
to  denote  two  afpe&s  of  the  arm. 

From  the  rotatory  motions  of  the  radius,  and 
its  varying  pofitions  with  regard  to  the  ulna  in 
various  cafes,  it  may  be  difficult,  in  certain 
places,  to  diftinguifh  the  afpecls  when  they 
happen  to  run  in  a  fpiral  courfe  ;  but  though 
this  difficulty  may  often  occur,  it  may  always 
be  removed  by  afcertaining  the  different  af- 
pe&s  at  the  joint  of  the  elbow,  when  the  ra- 
dius is  placed,  or  fuppofed  to  be  placed,  in  a 
Hate  of  fupination.  From  that  point  their  fpi- 
ral courfe  may  ealily  be  followed  in  oppofite  di- 
rections both  along  the  humerus  and  fore  arm. 

Proximal  and  dijlal  are  chofen  in  preference 
to  proximate  and  diftant,  as  being  no  parts  of 
colloquial  language ;  and  likewife  for  the  fake 
of  their  termination,  as  all  the  other  words  de- 
noting pojition  terminate  either  in  a  I  or  ar. 

Central  is  a  word  borrowed  indeed  from  col- 
loquial language;  but  here  can  occafion  no  am- 
I  2  biguity, 


132  NEW  TERMS  RELATING  TO 

biguity,  it  being  underftood  in  the  fame  lati^ 
tude  with  the  other  terms. 

As  for  the  terms  peripheral,  mejial,  and  der- 
mal, thefe,  or  words  of  a  fimilar  import,  were 
abfolutely  neceffary :  but  whether  or  not  more 
agreeable  founds  might  have  been  gotten  to  ex- 
prefs  their  fenfes,  was  a  fubject  on  which  I 
have  not  bellowed  very  much  inquiry. 

Having  now  £ttn  the  defects  of  the  terms 
denoting  pofition  in  the  trunk  and  extremities, 
and  tried  to  remedy  them,  let  us  next  fee  whe- 
ther or  not  there  be  any  defects  in  their  ex- 
preffion  when  applied  to  the  head.  In  the  hu- 
man fpecies  the  word  fuperior,  in  its  primary 
fenfe,  will  allude  to  a  part  of  the  frontal  bone, 
and  that  part  of  the  parietals  which  lies  near 
the  fagittal  future.  It  will  likewife  allude  to 
iimilar  parts  in  the  meep  and  ox,  and  fome 
other  quadrupeds  ;  but  were  thefe  quadrupeds 
to  alfume  the  erect  pofture,  the  parts  that  are 
fuperior  would  be  pofterior  :  and  were  man  to 
affume  the  pofture  of  the  quadruped,  the  parts 

that 


POSITION  AND  ASPECT.  133 

that  arefuperior  would  become  anterior.     Su- 
perior therefore,  in  thefe  cafes,  denotes  always, 
to  a  certain  extent,  fimilar  parts,  when  the  at- 
titudes of  the  two  fpecies  are  different;  and 
diffimilar  parts,  when  they  are  the  fame.     In- 
ferior, on  the  contrary,  fimilar  parts,  when  the 
attitudes   are  the  fame;  and  diffimilar  parts, 
when  they  are  different :  For,  in  the  natural 
and  ordinary  pofture  of  flanding  or  walking, 
Inferior  alludes  to  the  bafis  of  the  cranium 
in  the  human  fpecies,  but  to  the  mouth  and 
lips  of  thefe  quadrupeds;  yet  both  terms  would 
fignify  a  ftill  greater  variety  were  they  farther 
extended  to  birds,  fifhes,  reptiles,  and  infeds. 
Anterior  and  po/Ierior,  at  the  fame  time,  if  thus 
extended,  would  be  equally  vague ;  while  ex- 
ternal and  internal  would  be  almoft  an  endlefs 
fource  of  ambiguity.   But  the  force  of  this  rea- 
foning  will  appear  more  evident  from  the  fol- 
lowing Statement,  where   the  terms  are  ufed 
in  their  primary  fenfe,  and  applied  to  each

Are  as  faulty  when  applied  in  fome  of  their 
fenfes  to  the  regions  of  the  head  as  they  are 
in  other  parts  of  the  fyftem.  What  mean- 
ing, for  inftance,  can  we  affix  to  the  exter- 
nal and  internal  angle  of  the  eye  where  the 
eye  is  round,  where  it  is  lateral,  where  it  is 
vertical,  or  where  the  line  palling  from  one 
angle  to  the  other  runs  not  tranfverfely,  but 
longitudinally  with  refpect  to  the  head  ? 

^From  this  ftatement  it  mud  be  evident  that 
the  prefent  terms  for  denoting  Jituati  on  will  be 
attended  with  as  much  confufion  in  defcribing 
the  head  as  any  other  part  of  the  fyftem  ;  and 
that  other  terms  ought  to  be  employed,  if  we 
either  wifh  to  avoid  ambiguity,  or  make  ufe 
of  general  and  precife  language.  At  the  fame 
time,  it  will  readily  be  granted,  that  if  the

to

to  the  head,  new  terms  would  not  only  be  un- 
necessary, but  abfurdly  fuperfluous.  But  while 
anxious  to  avoid  an  improper  multiplication  of 
terms,  we  mud  recollect  that  two  or  three 
words,  having  each  a  definite  and  precife  mean- 
ing* are  not  fo  troublefome  and  dangerous  in 
fcience  as  one  word  with  two  or  three  meanings 
that  are  different ;  for  every  word  employed 
to  exprefs  two  or  three  objects  fpecifically  dif- 
ferent, muft  neceflarily  introduce  a  fort  of  con- 
fulion  into  our  ideas ;  tend  to  miflead  us  in 
the  paths  of  inquiry ;  and  unlefs  we  are  guard-

doing  this,  it  is  needlefs  to  obferve  that  thofe

mals,  we  muft  inftantly  perceive  that  Jiernal, 
dorfal,  atlantal,  and  facral,  can  do  no  more 
than  mark  the  relative  lituation  of  parts,  or  the 
different  politions  of  the  head  and  trunk  with 
reipect  to  one  another.  But  as  even  this  may 
be  an  object  of  fome  importance ;  as  it  may 
introduce  into  our  defcriptions  a  greater  degree 
of  clearnefs  and  precifion  ;  and  lead  to  con- 
clulions  in  phyfiology  that  may  be  both  inte- 
refting  and  ufeful — I  fhall  here  mow  the  man- 
ner in  which  the  application  of  fuch  terms  may 
be  extended  ;  and  fliall  take  firft,  in  the  way 
of  -illuftration, 


Atlantal  and  Sacral. 

In  applying  thefe  terms  to  the  head,  let  us 
call  the  line  which  follows  the  direction  of  the 
vertebral  column  from  the  facrum  to  the  atlas 
the  Vertebral  Line  ;  and  fuppofe  it  conti- 
nued perpendicular  to  the  plane  of  the  foramen 
magnum  till  it  fall  on  fome  bone  of  tire  cranium 

or

or  face.  Let  this  bone,  whatever  it  be,  in  that 
cafe  be  called  the  atlantal ;  we  fhall  find,  on 
inquiry,  that  the  parietal  bones  will  be  atlan* 
tal  in  one  fpecies,  the  frontal  in  another,  and 
fome  different  bone  in  a  third  \  that  the  angle 
formed  between  this  bone  and  the  vertebral 
line  will  vary  confiderably  in  different  animals  \ 
and  that  when  the  line  happens  to  fall  on  the 
fame  bone,  it  will  often  fall  on  a  different  part 
in  a  different  fpecies.  In  man,  for  inflance,  it 
will  fall  on  the  fagittal,  a  little  behind  the  co- 
ronal future ;  in  all  other  animals  it  will  fall 
more  towards  the  face.  In  the  ape,  it  will  fall 
on  the  frontal  bone,  a  little  before  the  coronal 
future  ;  in  the  dog  and  horfe,  as  far  down  as 
the  orbitary  ridge  \  in  the  mole,  the  rat,  and 
fome  other  quadrupeds,  it  will  flrike  on  fome 
part  of  the  nofe ;  in  frogs  and  ferpents,  will 
defcend  as  low  as  the  maxillary  curves ;  and 
in  fome  animals  may  pafs  obliquely  from  above 
downwards  through  the  bafis  of  the  head. 

If  the  term  facral  be  applied  to  the  head,  it 
mufl  always  denote  that  fide  which  is  oppofed 

to

to  the  atlantal,  and  may  eafily  be  found  from 
obferving  the  place  of  the  foramen  magnum, 
which  in  all  cafes  muft  be  necefiarily  facral. 
The  fituation  of  the  facral  fide  will  therefore 
vary  with  the  foramen,  which  in  human  fculls 
is  found  in  the  bafe  \  but  as  we  defcend  thro' 
quadrupeds  and  birds,  proceeds  backwards,  till 
in  ferpents  and  flfhes  we  find  it  at  that  part  of 
tHe  head  which  is  oppofite  to  the  mouth  or 
middle  part  of  the  maxillary  curves.  In  fhort, 
it  recedes  more  and  more  backwards,  towards 
the  one  extremity  of  the  head,  as  the  vertebral 
line  comes  more  and  more  forwards  towards 
the  other.  From  this  fixed  and  mutual  rela- 
tion we  may,  from  knowing  the  atlantal  point, 
afcertain  in  fome  meafure  the  fituation  of  the 
foramen  ;  obtain  fome  idea  of  the  form  of  the 
head,  of  its  relative  pofition  with  regard  to  the 
trunk,  of  the  moil:  ufual  pofture  of  the  animal 
in  motion;  and  a  variety  of  other  circum- 
fiances  that  neceifarily  depend  upon  thefe 
diflinclions,

Sternal  and  Dorsal. 

These  terms,  when  applied  to  the  head,  will 
fignify  parts  in  the  fame  plane,  in  planes  paral- 
lel, or  nearly  parallel  to  the  fternum  and  dor- 
fum  ;  and  mould  the  fternum  and  dorfum  be 
parallel,  thefe  planes  will  always  be  fternal  which 
are  on  the  fternal  fide,  and  thofe  dorfal  which 
are  on  the  dorfal  fide  of  the  vertebral  line. 

In  the  human  fpecies  the  whole  face  bound- 
ed by  the  chin,  the  hairy  fcalp,  and  the 
two  lateral  parts  of  the  head,  will  be  fternal. 
1 — In  fheep  and  oxen,  when  the  head  is  in  the 
ufual  pofition,  with  the  bafe  feemingly  at  right 
angles  to  the  vertebral  line,  the  maxillary 
curves  only  will  be  fternal. — But  in  ferpents 
and  frogs,  the  bails  of  the  cranium  will  be  found 
fternal,  while  the  maxillary  curves  will  become 
atlantal. 

In  the  human  fpecies,  the  word  dorfal  will 
denote  the  rifing  part  of  the  occipital  bone 
and  pofterior  part  of  the  two  parietals. — In 

fheep 


142  NEW  TERMS  RELATING  TO 

flieep  and  oxen,  not  only  a  part  of  the  occipi- 
tal bone,  but  the  upper  part  of  the  parietal 
arch,  thro'  its  whole  extent,  from  behind  for- 
wards, including  a  part  of  the  frontal  bone. — 
In  ferpents  and  frogs,  not  only  the  upper  part 
of  the  cranium,  but  likewife  moft  of  the  bones 
of  the  face,  which  are  not  on  the  fides  or  ba- 
lls of  the  head. 

It  feems  to  be  therefore  a  general  law,  that 
the  parts  of  the  head  which  are  atlantal  and 
flernal  in  man  mould,  in  defcending  through 
the  lower  animals,  gradually  approach  more 
and  more  to  the  dorfal  fituation,  and  the  parts 
which  are  facral  more  and  more  to  that  which 
is  fternal.  From  knowing  therefore  the  parts 
of  the  head  which  are  fternal  and  dorfal,  we 
will  be  led  to  nearly  the  fame  general  conclu- 
fionsthat  we  drew  from  the  points  atlantal  and 
facral;  w7e  will  learn  the  relative  polition  of 
the  head  with  regard  to  the  trunk,  the  fitua- 
tion of  the  foramen,  the  uiual  attitude  of  the 
animal  in  motion,  the  form  of  the  cranium,  and 
how  far  it  deviates  from  die  human  fTiape.  We 

may

may  alfo  acquire,  in  this  way,  fome  general 
idea  of  the  nervous  fyftem,  The  proportion 
between  the  diameters  of  the  cranium  and  fo- 
ramen magnum  is  ufually  connected  with  the 
fhape  of  the  head  and  the  fituation  of  the  fo- 
ramen :  from  knowing  therefore  the  fhape 
and  fituation,  we  may  form  fome  idea  of  the 
relative  proportion  of  the  two  diameters ;  and 
from  knowing  the  proportion  of  the  two  dia- 
meters, we  may  know  the  proportion  between 
the  brain  and  the  fpinai  marrow;  and  as  the  fa- 
gacity  and  vital  energy  feems  to  be  regulated 
by  this  proportion,  we  hence  may  form  pretty- 
accurate  conjectures  with  refpecl  to  the  de- 
gree of  the  intellectual  functions,  the  tena- 
cioufnefs  of  life,  and  power  of  reproduction 
poffefied  by  the  animal. 

But  altho'  the  extenfion  of  thefe  terms  may 
be  highly  ufeful  in  many  phyfiological  deduc- 
tions, they  are  not  adapted  to  the  feparate  ana- 
tomical defcription  of  the  head.  In  the  cafe 
of  a  defcription,  the  bead,  which  eoniifts  of 
two  parts,  the  cranium  and  face,  neceliarily  re- 
quires 


144  N£w  TERMS  RELATING  TO 

quires  terms  of  its  own,  as  well  as  the  trunk 
and  the  extremities ;  and  thefe  terms  might 
be  borrowed  from  the  bones,  if  it  were  pof~ 
fible  in  that  way  to  make  them  precife.  But, 
unfortunately,  in  the  cranium  there  are  no 
bones,  not  even  the  ethmoidal,  entirely  confi- 
ned to  one  of  its  afpe&s ;  and  the  bones  of  the 
face  vary  fo  much  in  their  form,  proportion, 
and  general  appearance  in  different  animals, 
that  they  are  equally  unfit  for  our  purpofe. 
We  mud  therefore  endeavour  to  contrive  names 
for  defcribing  the  afpects  of  the  cranium  and 
face,  that  contain  no  allufion  to  the  fituation  of 
particular  parts. 

Taking  the  head  as  a  whole,  thefe  afpecls 
mould  be  eight  in  number  ;  but  fuppofing  the 
falx  a  mejial  plane,  dividing  it  into  two  fi- 
milar  halves,  they  will  amount  to  nine  ;  and 
by  dividing  it  into  cranium  and  face,  a  tenth 
may  be  necefiary.  But  as  dermal \  central,  dex- 
tral,  Jiniftral,  and  mejial,  are  equally  applica- 
ble to  the  head  and  trunk,  we  only  require  five 
that  are  new :  two  for  the  bafe  and  crown  of 

the 


POSITION  AND  ASPECT.  1 45 

the  head,  two  for  the  hind  and  fore  part  of  the 
cranium,  and  one  for  the  face. 

The  bafe  and  crown  of  the  head,  which  are 
oppoiite,  may  be  called  the  Basilar  and  Co- 
ronal afpects. 

Between  thefe  tw7o  and  the  lateral  afpects 
there  is  a  projecting  part  of  the  cranium  be- 
hind, which  the  Romans  called  occiput,  and 
the  Greeks  inion.  The  Greek  word  is  prefer- 
able to  the  Latin,  as  it  does  not  convey  any  al- 
lufion  to  the  occipital  bone,  which  is  found 
in  two  different  afpects,  the  bajilar,  and  that 
which  may  now  be  called  Inial. 

In  the  oppoiite  extremity  of  the  cranium* 
where  the  nafal  bones  are  found  connected 
with  the  os  frontis,  there  is  a  part  w,hich  fome 
anatomifls  who  have  written  in  Latin  have 
called  glabella.  This  particular  afpect  of  the 
cranium,  the  afpect  which  is  always  oppofed 
to  the  inion,  may  be  named  Glabellar. 

The  part  of  the  face  which  is  placed  at  the 

greateit  diftance  from  the  inion,  following  the 

courfe  of  a  ftraight  line,   is  in  fome  animals  a 

part  of  the  inferior,  in  others  a  part  of  the  fu- 

K.  perior 


I46  NEW  TERMS  RELATING  TO 

perior  maxillary  bone,  or  in  birds,  of  the 
mandibles  which  correfpond  to  them,  this 
diftant  part  of  the  face,  whatever  that  happens 
to  be,  may  be  called  the  Antinion. 

So  that  the  ten  afpecls  of  the  head  will  be 
the  Dermal,  Central,  and  Mesial,  the  Dex- 
tral  and  Sinistral,  the  Coronal  and  Ba- 
silar, the  Inial,  Antinial,  and  the  Glabel- 
lar. 

Of  the  laft  feven,  if  lines  be  drawn  between 
every  two  of  the  oppofite  afpects,  they  will 
conftitute  the  four  following  diameters :  The 
Dextro-sinistral,  theCoRONO-BASiLAR,  the 
Inio-glabellar,  and  the  Inantinial*.  The 
two  former  may  be  taken  at  different  places  of 
the  cranium,  towards  the  glabella,  where  it  has 
in  general  the  lead  depth  and  the  lean:  breadth, 
and  towards  the  inion,  where  the  depth  and 
breadth  are  ufually  greateft ;  the  firft  behind 
the  temporal  procefTes  of  the  os  frontis ;  and  the 
other  oppofite  to  the  prominent  parts  of  the  pa- 
rietals,  or  of  the  parietal,  as  in  fheep,  oxen,

&c.  where  the  fagittal  future  is  found  only  in 
the  os  frontis,  and  where  one  bone  fupplies  the 
place  of  the  two  parietals.  In  this  way  we 
mall  have  two  dext'ro-jinijlral  and  two  corono- 
hajilar  diameters. 

The  meafurement  of  thefe  feveral  diameters 
will  mew  the  limits  of  varying  proportion  in 
the  heads  and  craniums*  of  the  fame  fpecies; 
and  when  applied  to  comparative  anatomy,  will 
difcovera  number  of  fpecific  differences  as  we 
defcend  in  the  fcale  of  being.    The  inio- glabel- 
lar, the  two  corono-bajilar,  and  the  two  dextro- 
finijlral,  or  tranfverfe  diameters,  will,  in  general^ 
be  found  to  have  a  lefs  proportion  to  the  inanti- 
nial  than  they  have  in  man.    The  inantinial  ap- 
pears therefore  to  have  fome  connection  with  the 
facial  angle,  which  gradually  diminifhes  as  the 
inantinial  diameter  increafes.     Should  any  of 
my  readers  require  an  explanation  of  this  an- 
gle, it  is  formed  by  two  lines,  one  drawn  from 
the  middle  of  the  meatus  audit orius  externus

to  the  inferior  part  of  the  noitril,  and  another 
called  the  facial  line,  drawn  from  the  fame 
part  of  the  noftril  to  the  fuperciliary  ridge 
of  the  os  frontis.  In  fome  of  the  Grecian  an- 
tiques, this  is  an  angle  of  100  degrees,  and  in 
fome  negroes  an  angle  of  70.  When  beyond 
100,  the  face  is  monftrous;  when  below  70,  it 
is  that  of  a  brute.  Even  when  100,  the  face 
is  unnatural ;  and  it  is  very  feldom  indeed  that 
we  ever  find  it  fo  high  as  90. 

In  the  Grecian  antiques,  the  maxillary  bones, 
with  the  depth  and  firmnefs  of  maturer  years,  re- 
tain the  fhortnefs  peculiar  to  youth ;  and  are  ne- 
ver lengthened  fo  as  to  hold  a  quantity  of  teeth 
of  the  number  and  dimenfions  that  are  ufually 
found  in  the  jaws  of  an  adult.  The  brow  there- 
fore projects  beyond  the  face,  and  the  nofe  de- 
fcends  in  a  ftraight  line.  In  reafoning  coolly,  the 
form  would  ftrike  us  at  once  as  abfurd,  and  as 
an  unjuftifiable  deviation  from  nature;  but  the 
fenfes  and  paffions  get  interefted,  and  we  feel 
pleafed  with  the  genius  of  the  artift  who,  thus 
combining  with  tafte  and  judgment  whatever 
is  comely  and  beautiful  in  youth,  with  what  is 

noble 


POSITION  AND  ASPECT,  I49 

noble  and  dignified  in  age,  infenfibly  produces 
an  agreeable  impreflion.     Although  the  fea- 
tures be  rather  extraordinary,  we  feel  pleafed 
with  the  general  appearance,  in  the  fame  man- 
ner, as  we  like  to  fee  what  is  not  very  common ; 
a  fteady  and  prudent  manlinefs  in  a  child,  and 
a  certain  degree  of  fprightly  vivacity  in  an  old 
man.     But  ihould  it  be  aiked,  Why  a  fimilar 
projection  of  the  face  mould  be  lefs  agreeable 
than  that  of  the  forehead  ?  the  anfwer  is  ob- 
vious :  The  projection  of  the  forehead,  to  the 
extent  in  which  it  is  carried  in  the  Grecian  an- 
tiques, only  furpafles  our  flandard  of  excel- 
lence ;  and  fo  always  imprefTes  us  with  an  idea 
of  a  more  than  ufual  dignity  in  the  counte- 
nance.    The  projection  of  the  face,  on  the 
other  hand,  is  rather  below  our  ideal  flandard ; 
neceffarily  lengthens  the  inantinial  diameter  ; 
and  produces  an  appearance  that  is  very  near- 
ly approximate  to  the  brutes.    The  aflbciation 
of  our  ideas,  it  mufl  be  allowed,  has  alfo  its  in- 
fluence.    Many  of  the  Simiae,  though  beau- 
tiful in  themfelves,  become  exceedingly  ug- 
ly and  difgufting  when  viewed  as  men,  or  as

intended  imitations  of  our  fpecies ;  while  the 
longer  face  and  the  more  receding  forehead 
of  the  greyhound  are  deemed  elegant,  becaufe 
he  is  tried  by  a  ftandard  of  his  own,  and  no 
comparifon  fecretly  instituted  between  him  and 
man. 

The  facial  line  does  not  therefore  fhow  what 
is  beautiful  and  deformed  in  nature ;  but  mere- 
ly  afcertains  the  inclination  of  the  face  to  that 
line  which  is  drawn  from  the  ear  to  the  infe- 
rior part  of  the  noftril.     In  Camper's  figures, 
this  line  is  always  fuppofed  to  be  horizontal, 
and  drawn  from  the  middle  part  of  the  orifice 
of  the  meatus  auditorius  externus.  Did  Camper 
forefee  that  this  line  might  change  its  pofition 
while  the  form  of  the  head  continued  the  fame? 
In  the  young  fkeleton,  where  the  bony  meatus 
is  entirely  wanting,  and  where  the  line  muft 
confequently  be  drawn  from  the  middle  of  the 
ring  to  which  the  membrana  tympani  is  attach- 
ed, will  its  direction  be  found  the  fame,  with 
regard  to  the  face,  as  in  the  adult  ?  Certainly 
not.     The  membrana  tympani,  or  bottom  of 
the  external  meatus,  is  more  forward,  inward, 

and 


POSITION  AND  ASPECT.  151 

and  downward,  than  the  orifice  where  it  is 
joined  to  the  concha  ;  and  therefore  the  di- 
rection of  this  line,  with  regard  to  the  head, 
muft  vary  with  the  changes  and  relative  fitua- 
tion  of  the  meatus;  a  fituation  which  is  known 
to  be  different  in  different  animals.  In  the  cat, 
for  inflance,  it  enters  horizontally;  is  more  ba- 
filar  than  the  zygomatic  arch  ;  and  its  bajilar 
margin,  if  we  now  may  venture  to  ufe  that  lan- 
guage, is  more  bafilar  than  the  bafe  itfelf,  or 
advances  farther  in  the  bafilar  direction. 

In  the  babyrouffa,  the  meatus  is  long ;  runs 
from  the  tympanum  in  the  coronal,  lateral,  and 
inial directions;  or  rifes upwards, outwards,  and 
backwards,  fuppofing  the  erect  poflure  of  the 
animal,  and  the  bafe  of  the  head  at  right  angles 
to  the  vertebral  column.  In  this  animal  the 
external  orifice  of  the  meatus  is  more  coronal 
than  the  zygoma,  or  more  towards  the  crown 
of  the  head.  If  in  thefe  two  inflances,  there- 
fore, we  were,  in  the  manner  of  Camper,  to 
draw  the  horizontal  line  from  the  middle  of 
the  orifice  of  the  meatus,  we  mould  draw  it 
from  different  points  of  the  head,  or  from 
K  4  points 


152  ®EW  TERMS  RELATING  TO 

points  that  do  not  correfpond  in  relative  fitua- 
tion. 

The  other  point  to  which  it  is  drawn  is 
likewife  variable  with  refped  to  polition.  In 
man  and  quadrupeds  it  is  found  near  the  max- 
illary curve.  In  birds  it  is  fometimes  at  one 
extremity  of  the  maxilla,  fometimes  at  the 
other,  and  fometimes  in  the  middle.  In  ceta- 
ceous animals,  the  fpirucula,  or  breathing  holes, 
run  in  a  direction  obliquely  from  the  bafe  to- 
wards the  corona,  and  terminate  in  the  face 
near  the  glabellar  part  of  the  cranium.  The 
angle  formed  by  the  facial  line  and  the  hori- 
zontal, in  fuch  cafes,  would,  in  fome  inftan- 
ces,  be  larger  than  the  human  t  For  thefe 
reafons,  if  we  wifh  to  afcertain  the  fhape  of 
the  head  in  any  refpect,  it  would  be  more 
accurate,  inftead  of  this  auri-nafal  line,  to 
draw  a  bajilar,  or  even  two  bajilar  lines ;  one 
running  along  the  bafllar  fide  of  the  palatine 
plate  of  the  upper  maxilla,  and  another  along 
the  bafe  of  the  lower  maxilla,  and  both  produ- 
ced, till  they  meet  the  facial  line.  With  this 
line?   which  is  likewife  produced,  they  will 

form 


POSITION  AND  ASPECT,  153 

form  two  angles ;  one,  the  baji-facial  of  the  fu- 
perior  or  coronal;  and  the  other,  the  baji-fa- 
cial  of  the  inferior  or  bqfilar  maxilla. 

Where  the  line  drawn  on  the  palatine  plate 
is  interrupted  by  the  alveolar  procefs,  a  line 
may  be  drawn  from  the  dermal fide  on  the  fup- 
pofed  continuation  of  the  palatine  plane. 

Where  the  palatine  plate  is  convex  or  con- 
cave, the  line  is  fuppofed  to  be  drawn  on  a  plane 
that  pafTes  through  its  inial  and  antinial  extre- 
mities; and  in  the  other  maxilla,  if  thebafilar 
lide  be  convex  or  concave,  it  is  fuppofed  to  be 
drawn  on  a  plane  that  proceeds  from  the  angles 
to  the  bajilar  or  lower  fide  of  the  curvature. 

As  the  palatine  plate  is  either  parallel,  or 
nearly  parallel  to  the  plane  of  the  mouth,  the 
angle  formed  by  that  plane  and  the  facial 
line  may  alfo  be  taken,  and  diftinguifhed 
from  the  others  by  the  name  of  the  ori-facial 
angle  ;  nay,  as  this  angle  may  always  be  eafi- 
ly  and  accurately  taken  in  the  living  body,  it 
may  oftener  be  ufeful  in  afcertaining,  analogi- 
cally, the  inclination  of  the  face  and  the  form 
of  the  head  than  the  other  two.

dy attention  to  thefe  lines,  diameters,  and 
angles,  muft  lead  to  more  clear  and  precife 
ideas  than  we  hitherto  have  had  upon  the 
comparative  anatomy  of  the  head ;  and  if 
ever  a  language  peculiarly  fitted  to  exprefs 
thefe  ideas  were  generally  adopted,  no  anato- 
mift,  no  phyfiologift,  or  phyfiognomift,  would 
prefume  to  indulge  in  vague  declamation ; 
or  venture,  with  any  reafon,  to  complain, 
from  affectation  of  myftery,  or  of  fomething 
new,  that  he  wanted  terms  to  exprefs  his 
thoughts  and  his  lingular  obfervations. 

It  is  true  that  every  object  in  nature  will  ex- 
hibit a  number  of  difcriminating  characters  if 
accurately  examined,  and  every  one  may  have 
marks  of  his  own  by  which  he  diftinguifhes 
them ;  but  if  every  one  mould  defcribe  an  object 
only  by  marks  peculiar  to  himfelf,  we  fhould  ne- 
ver difcover  that  the  object,  was  the  fame ;  but 
rather  conclude,  that  the  objects  were  as  diffe- 
rent 


POSITION  AND  ASPECT.  I  55 

rent  as  the  defcriptions.     In  this  way,  no  one 
could  poflibly  underfland  the  defcriptions  of 
another ;  and  one  might  defcribe  an  object  as 
new  which  had  been   defcribed  an  hundred 
times  before.     It  is  therefore  neceffary  to  at- 
tend to  marks  of  a  certain  kind,   particularly 
thofe  by  which  an   object  is  claflified  and  ar- 
ranged.    After  acquainting  us  with  thefe  cha- 
racters, we  come  to  know  the  genus  and  fpe- 
cies  to  which  it  belongs ;  and  then  an  author 
may  enumerate  as  many  characters  as  he  choo- 
fes,   for  now  we  begin  to  underfland  the  fub- 
ject  of  which  he  is  treating.     It  was  thus  by 
directing  the  attention  of  mankind  to  certain 
characters,  that  Linnaeus  taught  naturalifts  all 
to  fpeak  in  the  fame  language,  and  to  be  intel- 
ligible to  one  another  ;  and  it  is  by  adopting  a 
limilar  method  that  we  ever  can  expect,  on 
rational  principles,  to  improve  our  knowledge 
in  general  anatomy.     It  is  therefore  to  be  ho- 
ped that  were  anatomifts,   in  defcribing  the 
heads  of  different  animals,  always  to  give  us 
the  proportions  and  magnitudes  of  certain  lines, 

diameters. 


I5#  NEW  TERMS  RELATING  TO 

diameters,  and  angles,  we  fhould  very  foon  ac- 
quire more  general,  and  precife  information 
upon  that  fubjecl:  than  we  now  poffefs. 

As  an  accurate  knowledge  of  relative  por- 
tion is  likewife  of  the  greateft  importance  in 
anatomy,  we  mould  never  negledt,  where  it  is 
poffible,  to  mention  the  fituation  and  afped:  of 
every  part  that  is  worthy  of  notice.    A  careful 
attention  to  thefe  circumflances  will  gradually 
fecure  to  us  more  accuracy,  with  regard  to  de- 
fcriptions  in  furgery,  phyiic,  zoology,  and  an- 
atomy ;  will  render  our  knowledge  of  the  ufes 
and  functions  more  perfect ;  and  will  therefore 
give  more  than  an  ordinary  degree  of  clearnefs 
and  precilion  to  our  phyiiological  reafonings 
and  conclufions. 

The  terms  here  fuggefted  for  the  head  con- 
taining no  allufion  to  the  bones,  and  being  fome- 
what  different  in  principle  from  feveral  of  thofe 
which  have  been  fuggefted  for  the  trunk  and  ex- 
tremities, I  fhall  illuftrate  the  mode  of  applying 
them  by  a  few  examples.     Let  us  take,  for  in-

It  has  two  fides,  one  convex  and  the  other  con- 
cave ;  which,  in  point  of  afpecl,  are  dermal  and 
central.  In  point  of  fituation,  coronal  and  late- 
ral. It  has  four  margins,  which,  in  point  of  fi- 
tuation, are  likewife  found  coronal  and  lateral; 
but,  in  point  of  afpecl:,  glabellar,  mejial,  inial, 
and  bajilar.  It  has  alfo  four  angles,  each  an- 
gle lying  between  two  of  the  different  mar- 
gins ;  and  which  therefore  may  be  named  the 
glabello-mejial,  glabello- bajilar,  the  inio-mejial, 
and  the  inio-bajilar. 

Examining  this  bone  in  the  deer  and  fheep, 
where  we  fee  no  divifion  by  fagittal  future,  its 
two  furfaces  are  convex  and  concave  ;  and  in

what  different,  being  inial  and  lateral ;  and 
with  refpect  to  the  different  afpecls  of  its  four 
margins,  two  are  antinial,  one  coronal,  and  a 
fourth  bajilar.

it  joins  the  malar  bone,  lateral ;  and  where  it

it  is  inial,  or,  more  ftrictly  fpeaking,  inio-mejial. 
The  other  afpects  are  coronal,  bajilar,  lateral, 
and  mejial. 

In  thofe  animals  where  the  eyes  are  in  the 
lateral  parts  of  the  head,  the  pupil  is  dermal, 
the  entrance  of  the  nerve  mejial ;  the  other 
afpects  coronal,  bajilar,  inial,  antiniaL

Such

Such  language,  it  will  eafily  be  feen,  is  chiefly 
neceffary  in  comparative  anatomy,  where  we  foon 
learn  that  the  lingular  variety  which  we  difco- 
ver  in  the  actions,  habits,  and  functions  of  ani- 
mals is  principally  owing  to  certain  changes  or 
modifications  in  the  intimate  ftru&ure,  in  the 
relative  magnitude,  fituation,  and  afpects  of  the 
different  organs ;  and  where  we  perceive,  that 
the  Author  of  Nature  has  by  thefe  changes 
varied  the  fame  general  fabric  innumerable 
ways ;  given  it  a  thoufand  different  inftindts, 
appetites,  and  paffions ;  adapted  it  to  every 
element  and  climate,  and  to  endlefs  diverfities 
with  refpect.  to  food  and  the  modes  pf  life. 

As  the  means  by  which  He  has  produced  thefe 
effects  cannot  be  thought  unworthy  of  inquiry, 
a  language  calculated  to  exprefs  the  circum-

wifdom,  and  forefight,  by  which  the  great 
Sovereign  of  the  Univerfe  has  peopled  the  air, 
the  water,  and  the  earth,  with  innumerable 
myriads  of  animated  beings ;  varied  the  fame

In  expreffing  pofition,  direction,  or  attach-

compounded  by  fubftituting  o  for  the  al  or  ar 
of  the  firft  column,  and  by  adding  it  to  the  en 
of  the  fecond.  Thus  the  pofition  of  the  heart

or  jiniftro-facrad.  In  defcribing  the  direction 
of  the  fuperficial  femoral  artery,  we  may  fay 
that  at  firft  it  is  rotulo-tibial,  then  tibio-popli- 
teal.  In  mentioning  the  direction  of  the  farto- 
rius,  we  may  fay  that,  like  the  artery,  it  is  at 
firft  rotulo-tibial,  then  tibio  popliteal,  and  at  laft,

Thus  in  expreffing  its  origin  and  infertion,  I 
would  not  think  of  uling  the  word  Mo- tibial, 
but  ilieno  tibien.  In  many  defcriptions,  though 
this  minutenefs  may  not  be  necefTary,  it  is  al-

which  are  eafily  underftood  without  any  afr 
liftance  from  a  figure. 

The  four  lines  in  which  the  trunk  and  part 

of  the  neck  are  inclofed,  exhibit  the  attentat, 

facrat,  dextraly   and  Jiniftral  afpe&s,    marked 

at.fac.  d.lf.i  (d.L  for  dextral  or  lateral,  and 

././.  for  Jiniftral  or  lateral). 

The  line  drawn  in  the  middle,  marked  mef. 

is  the  flernal  edge  of  the  mejial  plane,  palling 

through  the  body  from  the  Jternal  to  the  dor-

teral halves. 

In  the  atlantal  extremities,  the  four  dotted 
lines  marked  r.  u.  th.  and  an.  {how  the  radial, 
ulnar,  thenql,  and  anconal  afpecls.  Where  the 
radius  is  in  a  (late  of  pronation,  the  afpecls 
appear  to  crofs  one  another  towards  the  car* 
pus. 

In  the  Jacral  extremities,  other  four  lines 
of  the  fame  kind,  marked  tib.fib.  rot.  and  pop. 
fhow  the  tibial,  fibular,  rotular,  and  popliteal 
afpe&s.  From  the  relative  position,  however, 
of  the  leg  and  foot  towards  the  ancle,  thefe 
£ines  convey  only  a  general  idea  of  thofe  af- 
pecls, which  are  very  eafily  diftinguifhed  in 
the  ikeleton  and  living  body. 

In  both  kinds  of  extremities,  the  lines  mark- 
ed prox.  and  dijl.  fhow  the  proximal  and  dijlal 
afpects.

Plate  V.  fhows  farther  how  the  afpecls  of 
the  head  vary  with  refpecl  to  the  trunk  in  dif- 
ferent animals ;  and  how  the  parts  that  are  at- 
lantal  in  man,  become  dorfal ;  the  parts  that 
are  inial,  facral ;  the  parts  that  are  bafilar, 
flernal;  and  the  parts  that  are  flernal,  atlcpn- 
tal  as  we  defcend  in  the  fcale  of  being.    Thefe 
afpe&s  of  the  head,  however,  will  have  other 
pofitions  with  regard  to  the  trunk,  according 
to  the  motions  of  the  living  animal;  and  diffe- 
rent parts  may  in  fuccefiion  be  flernal,  dorfal \ 
atlantal,  and  facral.    To  guefs  therefore  at  the

is  definite.  The  poiition  here  fuppofed  is  that 
where  the  vertebral  line  is  continued  through 
the  cranium  at  right  angles,  or  perpendicular 
to  the  plane  of  the  foramen  magnum.
