clean,  yellowish-white  color,  free  from  smell,  and  soon  becomes  hard 
and  pulverulent.  To  this  I  may  add,  it  is  quite  soluble  in  cold  alco- 
hol, its  spirituous  solution  remaining  unchanged  even  at  a  very  low 
temperature. 
To  test  its  merits,  a  preparation  of  soap  liniment  was  made  by  sub- 
stituting the  Castile  by  it,  and  when  subjected  to  low  temperature 
(32°  F.),  it  remained  perfectly  transparent,  while  the  officinal  prepa- 
ration became  quite  thick. 
Evidently  a  soap  richest  in  oleic^acid  and  containing  the  least  percent- 
age of  stearic  and  palmitic  acids  is  the  best  for  making  liquid  sapona- 
ceous preparations.  Castor-oil,  it  seems  to  me,  furnishes  us  one  com- 
ing nearest  to  this  qualification  of  any  we  possess. 
Note. — -In  his  thesis,  "  Saponification  of  Castor-oil,"  Mr.  Charles 
H.  Clark  advocated  the  substitution  of  a  soda  soap  of  this  oil  for  Cas- 
tile soap  in  soap  liniment.  Samples  of  the  soap,  and  of  soap  liniment 
and  soap  plaster  made  with  it,  have  been  in  the  possession  of  the 
Philadelphia  College  of  Pharmacy  for  the  last  ten  months. — Editor

Dissolve  the  sulphate  of  iron  in  three  ounces  of  boiling  water,  and 
the  phosph.  soda  in  five  ounces  of  boiling  water.  Mix  the  solutions 
in  a  porcelain  bottle  with  a  tight-fitting  stopper,  and  instantly  insert 
the  stopper  so  as  to  exclude  both  light  and  air.  Set  aside,  that  dou- 
ble decomposition  may  ensue  and  the  phosph.  of  iron  be  precipitated.
