lute  acid  and  water,  the  fatty  acids  were  cold  pressed  and  hot  pressed 
in  the  usual  way,  and  the  result  was  a  stearic  acid  higher  in  melting- 
point  and  greater  in  quantity  than  could  be  produced  in  any  other 
way,  and  an  oleic  acid  excellently  fitted  for  the  manufacture  of  soap 
and  other  purposes.  One  of  the  greatest  advantages  of  the  process 
was,  that  all  operations  were  conducted  in  open  tanks,  boiled  with 
steam  not  exceeding  35  lbs.  pressure. 
Mr.  Carpenter  stated  that  he  was  at  present  engaged  in  applying 
this  process  to  palm  oil  and  other  vegetable  fats,  and  he  illustrated 
his  paper  with  specimens  of  the  various  stages  of  manufacture. —

CARBOLIC  ACID  AND  CREASOTE. 
By  Pkofessor  Fluckiger,  Bern. 
A  good  plan  for  distinguishing  these  two  substances  is  as  follows  : — - 
Parts. 
Take  a.  Solution  of  Perchloride  of  Iron  about  1*34  spec.  gr.    .  1 
b.  Creasote,  that  is  to  say,  the  liquid  to  be  tested  for  Cre- 
asote, .  .  .  .9 
e.  Alcohol,  containing  about  85  per  cent,  of  absolute  Al- 
cohol,        .  .  .  .  .  .5 
d.  Water,       ......  60 
Now  a-\-b  mixed  assume  no  peculiar  color. 
a-^b^c  furnish  a  green  solution. 
a-^b-^c+d  form  a  turbid  mixture  of  a  dingy  brownish  co- 
lor, drops  of  creasote  being  separated. 
On  the  other  hand,  in  the  case  of  carbolic  acid,  suppose  like- 
wise— 
a.  The  above  ferric  solution,  weighing  equally       .  .  1 
/?.  Carbolic  Acid  (phenol),       .  .  .  .  9 
y.  Spirit  of  Wine,  as  above,  .  .  .  .5 
d.  Water,         ......  60 
Now  «-f-/3  will  show  a  yellowish  hue. 
a-\-^-\-y  yield  a  clear  brown  liquid. 
a-\-fi-\-y-{-d  display  a  beautiful  permanently  blue  solution,  with- 
out separation  of  carbolic  acid,  or  the  few  drops  sinking  down  may  be 
redissolved  by  shaking.
