wake,  and  then  clear  consciousness  ;  eyes  deeply  sunk ;  face 
dark  red,  which  turned  pale  as  soon  as  the  vomiting  of  green 
masses  mixed  with  blood  commenced  ;  belly  inflated,  and  very 
tender  and  painful  ;  pulse  quick,  hard  and  short,  changeable ; 
skin  hot,  extremities  cool ;  tongue  dry,  but  no  drink  was  asked 
for ;  stools  slimy,  with  bloody  stripes,  but  painless. 
Dr.  H.  commenced  the  antiphlogistic  treatment,  internally 
purgatives  with  ether  and  ammonia,  on  account  of  the  loss  of 
strength,  and  with  opium  and  valerian  to  the  girls,  on  account 
of  their  convulsions.  The  next  day  all  the  symptoms  were  milder  ; 
prescribed  an  emulsion  of  oil ;  the  youngest  girl  still  suffered  from 
drowsiness  and  vomiting ;  treatment  with  cold  fomentations,  oil 
clysters  and  sinapisms  was  continued.  On  the  18th  day  all  had 
recovered.  Exanthemata,  as  described  by  Niemann,  swelling  of 
the  tongue  or  head,  was  not  observed. 
These  fungi,  according  to  all  botanists  and  pharmacologists, 
are  classed  with  the  innocent  and  eatable  ones,  and  have  always 
been  eaten  without  any  bad  consequences.  The  present  case, 
however,  seems  to  indicate  that  all  fungi,  under  certain  condi- 
tions, even  the  most  innocent  ones,  are  capable  of  furnishing  the 
characteristic  fungus-poison  ;  but  these  conditions  are  yet  un- 
known.— Deutsche  Klinik,  1865  ;  Dr.  WachteVs  Zeitsehr.,  1855. 
Poisoning  of  Chickens.     JDy  X.  Landerer. 
The  author  was  judicially  invested  with  the  chemical  examina- 
tion of  poisoned  chickens,  which  he  found  were  killed  by  orpi- 
ment,  the  yellow  sulphuret  of  arsenic.  Not  a  trace  of  the  poi- 
son was  found  in  the  stomach  and  entrails ;  it  had  all  remained 
in  the  crop,  from  which  place,  consequently,  it  had  developed 
its  deadly  power. — -Wittsteins  Viertelj.  v.,  352. 
NEW  PROCESS  FOR  THE  PREPARATION  OF  FERROCYANIDE 
OF  POTASSIUM. 
By  Richard  Brunnquell. 
This  process  depends  on  the  conversion  of  ammonia  into 
cyanide  of  ammonium  by  ignition  with  charcoal  or  carbonaceous 
matters ;  and  its  principal  peculiarity  consists  in  the  conversion
