Poisonous  properties  of  Bichromate  of  Potassa. 
Pirogoff  and  Zablotzky  have  made  experiments  which  confirm 
those  of  Ducatel  and  Schindler,  made  with  men,  and  of  Jaillard 
undertaken  with  animals.    The  results  are  : 
1.  Bichromate  of  potasssa  belongs  to  the  acrid  metallic 
poisons,  in  the  same  class  with  arsenious  acid  and  corrosive  sub- 
limate. 
2.  From  1  to  6  grains  given  only  once,  cause  disorders  of  the 
digestive  organs,  and  sometimes  death. 
3.  The  anatomico-pathological  changes  are  analogous  to  those 
caused  by  arsenious  acid  and  sublimate. 
4.  The  best  antidotes,  as  long  as  vomiting  has  followed,  are 
bicarbonate  of  soda  and  magnesia  ;  the  treatment  afterwards  is 
analogous  to  that  of  poisoning  with  acrid  substances. — Ann,

Sulphuret  of  Iron  for  Chemico- Legal  Examinations. 
By  Dr.  Rud  Kemper  and  Fr.  Meyer. 
The  authors  have  tried  to  solve  the  question  whether  a  pure 
sulphuret  of  iron,  free  of  arsenic,  is  necessary  for  the  genera- 
tion of  sulphuretted  hydrogen  in  chemico-legal  analysis  ?  The 
gas  of  2  oz.  of  sulphuret  of  iron  was  washed  and  conducted  into 
a  solution  of  8  grs.  chloride  of  mercury  in  1  oz.  hydrochloric 
acid  ;  from  thence,  after  having  been  washed  again,  into  3  oz. 
nitric  acid  of  1.20  specific  gravity.  The  sulphuret  of  mercury 
was  free  of  arsenic ;  not  a  trace  of  it  could  be  detected  in 
Marsh's  apparatus. 
The  nitric  acid,  after  evaporation,  was  treated  in  the  same 
apparatus  and  not  a  trace  of  arsenic  was  found.  The  sulphuret 
of  iron,  however,  the  authors  have  shown  to  contain  arsenic. 
They  accordingly  come  to  the  conclusion  that  the  sulphuret  of 
iron,  obtained  by  melting  together  iron  filings  and  sulphur,  and 
which  contains  arsenic,  yields  a  sulphuretted  hydrogen  free  of 
arsenic,  which  may  be  used  in  chemico-legal  examinations.—

Poisoning  by  Oil  of  Turpentine. 
Mr.  Marchal,  in  the  Academy  of  Paris,  on  Dec.  10,  1855, 
described  a  case  of  poisoning  occurring  to  a  woman  who  had
