alcohol,  nitric  acid,  all  precipitated  albumen.  The  boiled  and 
filtered  juice  gave  reactions  indicating  the  presence  of  sugar  (in 
considerable  quantity),  soda,  magnesia,  lime,  phosphoric  acid  (in 
considerable  quantity),  sulphuric  acid  (a  minute  proportion), 
chlorine.  Bichloride  of  platium  gave  a  muddy  molecular  yellow 
deposit ;  tannic  acid,  a  fine  fiocculent  precipitate  ;  perchloride  of 
iron  caused  a  precipitate,  but  neither  the  per-  nor  proto-salts  pro- 
duced any  discoloration. 
Dec.  10. — At  11.30  A.  M.  I  took  feii  with  a  litte  water.  I 
remained  quiet,  and  was  engaged  in  close  study  all  the  rest  of 
the  day.    No  effect  followed. 
Dec.  11. — At  8.30  A.  M.  took  ^i  of  bicarbonate  of  potash  in 
a  large  draught  of  water.  At  10.30  A.  M.  took  f^iii  of  the  suc- 
cus,  and  went  by  railway  into  the  City.  On  walking  back  again, 
about  three-quarters  of  an  hour  after  taking  the  conium,  I  sud- 
denly felt  a  heavy  clogging  sensation  in  my  heels,  and  as  I  went 
along  I  was  satisfied  that  this  was  due  to  impairment  of  muscular 
power.  After  walking  about  a  mile  up-hill  this  sensation  was 
very  decided,  and  on  putting  a  foot  upon  the  scraper  at  the  door  of 
the  hospital  the  other  leg  felt  hardly  sufficient  to  support  me.  It 
was  a  dark  foggy  day,  and  I  could  not  test  my  vision  for  distant 
objects  with  any  certainty,  but  on  looking  at  a  blazing  fire  at 
the  distant  end  of  the  ward  I  felt  giddy,  and  I  seemed  to  want 
power  in  my  eyes  in  order  to  fix  my  gaze  firmly  enough  to  get  a 
good  definition.  I  could  not  follow  the  rapidly  shifting  flames 
so  as  to  clearly  define  one  from  another.  I  felt  clumsy  in  my 
movements.  I,  was  quite  sure  of  them,  but  I  felt  that  I  needed 
to  make  an  effort  to  control  my  legs.  By  the  time  I  had  finished 
my  visit  (1  P.  M.)  these  effects  had  completely  passed  off,  and  I 
walked  away  briskly  a  distance  of  two  miles.  The  maximum 
effect  was  manifest  about  an  hour  and  a  quarter  after  taking  the 
hemlock. 
Dec.  13,  At  11  A.  M. — Took  f^iii  of  succus,  and  experienced 
the  above-mentioned  effects  in  only  a  very  slight  degree.  The 
pulse  and  pupils  remained  natural.  I  was  pretty  actively  en- 
gaged the  hour  following  the  dose. 
Dec.  15,  At  10.15  A.  M. — Took  %iv  and  immediately  walked 
a  distance  of  three  miles.  Felt  a  repetition  of  the  symptoms  which
