lead,  which  differs  from  lead  plaster  only  in  containing  a  smaller 
proportion  of  oxide  of  lead,  is  to  be  agitated  with  at  least  ten  or 
fifteen  times  its  weight  of  ether,  in  a  bottle,  until  it  is  com- 
pletely disintegrated.  The  resulting  liquid  is  transferred  to  a 
filter  and  closely  covered ;  an  ethereal  solution  of  acid  oleate  of 
lead  passes  through,  and  a  residue  of  acid  stearate  or  margarate 
of  lead  is  left  on  the  filter.  To  the  ethereal  solution,  add 
aqueous  muriatic  acid  as  long  as  chloride  of  lead  is  precipitated, 
shake  thoroughly,  and  pour  oif  the  resulting  ethereal  solution 
of  oleic  acid,  recover  the  ether  by  distillation,  and  the  residue 
in  the  retort  will  be  nearly  pure  oleic  acid. 
To  make  the  oleate  of  soda,  add  two  fluidrachms  of  oleic  acid 
to  one  pint  of  boiling  water,  and  then  solution  of  pure  caustic 
soda  very  gradually,  until  a  clear  solution  is  effected,  very  care- 
fully avoiding  an  excess  of  soda,  and,  when  cold,  add  sufficient 
water  to  make  the  solution  measure  a  pint,  if  necessary.  To 
this  standard  solution  of  oleate  of  soda,  add  one-half  its  bulk  of 
glycerin,  and  the  "  suds"  are  ready  for  use  in  blowing  bubbles. 
With  a  funnel  about  two  inches  in  diameter,  our  friend  has 
blown  bubbles  fully  sixteen  inches  in  diameter  and  of  remark- 
able permanency,  and  so  exceedingly  beautiful  and  interesting, 
that  he  felt  repaid  for  the  time  and  trouble  expended. — Ed.

PHARMACY  IN  BUENOS  AYRES — " THE  REVISTA  FARM- 
ACEUTICA." 
This  enterprising  representative  of  South  American  Pharmacy, 
in  the  form  of  a  monthly  periodical  of  24  octavo  pages,  is  published 
under  the  auspices  of  the  Society  of  Pharmacy  of  the  Argentine 
Nation  at  Buenos  Ayres. 
This  journal,  originally  published  as  a  quarterly,  has  been 
issued  in  its  present  form  for  the  past  year  or  two,  and  is  under 
the  management  of  a  commission  appointed  in  the  Society,  who 
are  aided  by  contributions  from  other  active  members  of  the  So- 
ciety, which  now  numbers  forty-four.  In  addition  to  its  list  of 
original  papers  we  observe  a  well  selected  review  of  the  foreign 
periodicals,  chiefly  European.
