OXALATE  OF  IRON  A  NEW  TONIC. 
6th.  In  many  experiments  where  we  have  observed  very  grave 
symptoms  and  apparent  death,  we  have  seen  the  animals  slowly 
return  to  life.  If,  as  is  reasonable  to  think,  the  action  on  man 
is  identical,  we  can  understand  why  the  Boundou  has  been  chosen 
by  the  Gabonese  for  a  proof  poison.  In  the  judgment  of  God. 
the  champions  recover  slowly  from  the  worst  symptoms,  but  are 
restored  gradually  to  health,  seemingly  recalled  to  life  by  the 
divinity,  jealous  of  demonstrating  their  innocence. — Comptes

ON  A  METHOD   OF   DISTINGUISHING  ARSENIURETTED 
HYDROGEN  FROM  ANTIMONIURETTED  HYDROGEN. 
By  M.  Dragendorff. 
This  process  is  founded  on  the  action  exercised  by  solid 
caustic^potassa,  in  fragments,  on  antimoniuretted  hydrogen,  pre- 
cipitating the  metal  from  it,  whilst  no  such  effect  is  produced  on 
arseniuretted  hydrogen.  If,  therefore,  a  mixture  of  the  two 
gases  is  passed  through  a  tube  filled  with  fragments  of  the 
alkali  a  complete  separation  is  effected,  and  the  arsenical  gas 
may  be  burned  separately.  The  fragments  are  coated  with  a 
brilliant  layer  of  antimony.  A  ley  of  potassa  sp.  gr.  1.25.  has 
but  little  effect.  When  the  mixture  of  antimony  and  potassa  is 
exposed  to  the  air  the  former  is  oxidized,  and  assumes  the  form 
of  antimoniate  of  potassa  when  the  mixture  is  placed  in  contact 
with  water.- — Jour,  de  Pharm.  Janv.  1867. 
OXALATE  OF  IRON  A  NEW  TONIC, 
The  following  communication  from  Mr.  J.  Emerson  Reynolds 
has  been  addressed  to  1  The  Medical  Press  and  Circular'  of  Nov, 
28. — "  Allow  me  to  draw  your  attention  to  a  preparation  of  iron, 
which  lias  been  much  neglected,  if  not  altogether  overlooked. 
I  refer  to  the  oxalate  of  the  protoxide  of  iron.  Having  lately 
used  it  in  cases  requiring  the  exhibition  of  a  compound  of  the 
metal,  I  observed  that  it  was  borne  with  remarkable  ease  by  the 
stomach,  possessed  little  if  any  astringency,  and  produced  the 
usual  constitutional  effect  with  sufficient  rapidity.    The  salt  is
