Preparation  of  a  Drying  Oil  for  Zinc  Paint. — In  order  to  avoid  the 
use  of  oxide  of  lead  in  making  drying  oil  for  zinc  paint,  oxide  of  manga- 
nese has  been  proposed  a3  a  substitute.  The  process  to  be  adopted  is  as 
follows : — 
The  manganese  is  broken  into  pieces  about  the  size  of  peas,  dried,  and 
the  powder  separated  by  means  of  a  sieve.  The  fragments  are  then  to  be 
introduced  into  a  bag  made  of  iron  wire  gauze.  This  is  hung  in  the  oil 
contained  in  an  iron  or  copper  vessel,  and  the  whole  heated  gently  for 
twenty-four  or  thirty-six  hours.  The  oil  must  not  be  allowed  to  boil,  in 
which  case  there  is  great  danger  of  its  running  over.  When  the  oil  has 
acquired  a  reddish  color,  it  is  to  be  poured  into  an  appropriate  vessel  to 
clear. 
For  100  parts  of  oil  ten  of  oxide  of  manganese  may  be  employed,  which 
will  serve  for  several  operations  when  freshly  broken  and  the  dust  separated. 
Experience  has  shown,  that  when  fresh  oxide  of  manganese  is  used,  it  is 
better  to  introduce  it  into  the  oil  upon  the  second  day.  The  process  like- 
wise occupies  a  longer  time  with  the  fresh  oxide.  Very  great  care  is 
requisite  in  this  operation  to  prevent  accident,  and  one  of  the  principal 
points  to  be  observed  is,  that  the  oil  is  not  overheated.  If  the  boiling 
should  render  the  oil  too  thick,  this  may  be  remedied  by  an  addition  of 
turpentine  after  it  has  thoroughly  cooled. — Pharm.  Journal,  Dec.  1,  1853?

Means  of  Detecting  and  Separating  Copper  from  Brandy. — Bottiger 
states,  that  when  a  few  drops  of  olive  oil  are  added  to  brandy  containing 
copper,  the  whole  well  shaken  and  allowed  to  stand  until  the  oil  has  per
