Artificial  Meersechaum.  By  L.  Wagenmann. — If  carbonate  of  magne- 
sia be  mixed  with  an  eighth  of  its  weight  of  calcined  magnesia,  and  a  little 
paste  of  lime  obtained  from  calcined  marble  and  solution  of  soluble  glass 
added  to  it,  the  mass,  after  complete  drying,  is  not  unlike  meerschaum, 
and  may  find  employment  in  the  arts.  The  alkaline  salt  produced  is  ex- 
tracted by  water  from  the  dry  meerschaum,  which  is  then  boiled  with  wax.

Purification  of  Commercial  Oleic  Acid.  By  G.  W.  F. — Oleic  Acid,  which 
is  procured  in  the  manufacture  of  Spermaceti,  &c,  has  lately  come  into  use 
as  a  medicinal  agent,  on  account  of  its  power  of  dissolving  other  sub- 
stances, used  for  external  purposes  ;  but  as  we  find  it  in  commerce  it  is  not 
pure  enough,  containing  in  particular  a  surplus  of  sulphuric  acid.  To 
purify  this  commercial  Oleic  Acid,  we  dissolve  it  in  as  large  a  quantity 
of  cold  rectified  alcohol,  as  it  will  absorb,  and  allow  the  solution  to  stand 
quietly  for  several  days,  during  which  a  tallow-like  substance  is  deposited. 
This  is  immersed  in  a  large  quantity  of  clean  water  ;  the  particles  of  oil, 
which  float  on  the  diluted  alcohol,  are  removed,  and  the  whole  again  well 
shaken  after  a  little  more  water  has  been  added.  Now  filter  the  whole 
through  white  paper.  * 
The  alcohol  may  be  purified  again  by  agitating  with  charcoal  or  by  dis- 
tillation.— Druggists'  Circular.
