ON  THE  VARIOUS  ANTIDOTES  FOR  COPPER. 
effect  is  produced  by  the  sulphuretted  mineral  waters  ;  and  con- 
sidering that  sulphur,  in  the  channels  of  digestion,  forms  sul- 
phurets  (?),  which  act  as  diaphoretics  and  alteratives,  developing 
their  action  on  the  albuminous  substances  ;  that  the  sulphurets, 
by  the  influence  of  carbonic  acid  in  the  mesenteric  blood,  form 
a  little  sulphuretted  hydrogen  ;  that  they  pass  through  the  liver, 
oxydizing  and  forming  sulphites,  hyposulphites  and  sulphates  ; 
from  all  this  he  inferred  that  these  last  products,  and  not  the 
sulphurets,  must  be  used,  because  they  are  found  in  the  animal 
excretions,  when  a  somewhat  considerable  quantity  of  sulphur 
has  been  taken. 
If  a  solution  of  corrosive  sublimate  is  poured  into  the  white  of 
eggs,  until  a  thick  precipitate  is  formed,  a  few  drops  of  a  solu- 
tion of  sulphite  or  hyposulphite  of  soda  suffice  to  restore  the 
transparency  of  the  liquid.  The  same  will  be  observed,  if  blood- 
serum,  containing  some  cruor,  is  substituted  for  albumen.  The 
sulphite  of  soda,  however,  effects  a  solution  quicker  and  more 
perfect. 
Mialhe  asserts,  that  all  preparations  of  mercury  by  a  reaction 
with  the  chlorides  form  corrosive  sublimate  ;  then  the  immense 
importance  of  the  fact  of  the  solution  of  the  albuminate  of  mer- 
cury by  sulphite  of  soda,  is  at  once  obvious.  The  albuminate  of 
mercury  which  retains  the  mercury  in  the  body,  according  to  the 
above,  can  be  dissolved  and  excreted  by  the  preparations  of 
sulphur. 
Sulphite  of  soda  excels  all  others  for  its  dissolving  effect.  It 
may  be  commenced  with  eight  grs.,  the  dose  seldom  exceeding 
a  drachm  in  twenty-four  hours.  It  is  very  refreshing,  with  an 
after-taste  somewhat  like  roasted  hazel  nuts,  and  has  not  the 
local  irritating  properties  of  the  sulphurets.  It  is  soluble  in  four 
parts  of  cold  water,  and  may  be  given  in  sweetened  water  or 
lemon  syrup.  It  agrees  well  with  the  stomach  and  acts  diuretic.

Lac  Magnesiw  as  an  antidote  to  Phosphorus,  by  X.  Landerer. 
A  girl  ate  about  a  tablespoonful  of  the  well-known  phosphorus 
paste,  mistaking  it  for  rice-pap ;  the  white  vapors  arising  from 
the  mouth  soon  made  the  calamity  known,  and  I  was  applied  to 
for  help.   I  gave  her  freely  lac  magnesiae,  (magnesia  usta  stirred
