ing  anilin  by  means  of  arsenic  acid.  The  bare  suspicion  of  extraneous 
arsenic  finding  its  way  into  medicine  must  be  sufficient  to  insure  its 
instant  abandonment  by  those  who  have  not  already  suspected  that  the 
paper  contains  arsenic. — Phar.  Jour,  and  Trans.,  Oct.  27. 
Syrupus  Ferri  Phosphatis  cum  Quinia  et  Strychnia. —  After  re- 
viewing the  literature  on  this  preparation,  and  noticing  the  defects  of 
the  different  formulas  proposed  for  its  preparation,  Geo.  Masson  pro- 
poses the  following,  by  which  a  colorless  syrup  may  be  readily  obtained, 
of  full  strength  and  good  keeping  qualities.1 
The  syrup  should  be  preserved  from  the  air  in  bottles,  well-filled 
and  securely  stoppered  : 
R    Strychnia,  .  .  .24  grs. 
Quinias  sulph.,  .  .  860  grs. 
Ferri  sulph.,         .  .       4  ozs.    40  grs.  ) 
Sodas  phosph.,              .  12  ozs  >  Avoirdupois. 
Sacchari  purif.  contus.,  .      60  ozs.  J 
Acid,  phosph.  dil.,       .  48  ozs. 
Dissolve  the  quiniae  sulph.  in  aq.  dest.,  with  a  sufficiency  of  acid,  sulph. 
dil.,  precipitate  with  liq.  ammon.  q.  s.,  collect  on  a  filter,  wash  care- 
fullv,  avoiding  the  use  of  too  much  water,  and  add  to  the  acid,  phosph. 
dil.  in  which  the  strychnia  has  been  previously  dissolved.  Dissolve 
the  ferri  sulph.  in  Oii,  and  the  sodae  phosph.  in  Ov  of  recently-boiled 
distilled  water,  filter  the  iron  solution  if  necessary  to  remove  any  oxi- 
dation, allow  the  solutions  to  cool  to  I30°F.,  and  then  add  very  grad- 
ually, with  constant  stirring,  the  solution  of  soda  to  the  iron  ;  allow 
the  precipitate  to  subside,  remove  the  supernatant  fluid  and  wash  the 
ferrous  phosphate  by  decantation  with  recently-boiled  distilled  water, 
then  transfer  to  a  calico  filter,  express  quickly  the  remaining  liquid,  and 
dissolve  in  the  dilute  phosphoric  acid.  Finally,  add  the  sugar,  dissolve 
without  heat,  and  subsequently  add  a  sufficiency  of  distilled  water  to 
make  the  product  measure  96  fluidounces,  each  fluidrachm  of  which 
wiil  contain  1  grain  phosphate  of  iron,  1  grain  phosphate  of  quinia,  and 
one  thirty-secondth  grain  of  strychnia. — Phar.  Jour,  and  Trans.,  Dec.  22.
