As  an  objection  to  this  plan  of  treating  and  reviving  corks,  it  may 
be  urged  that  there  may  be  a  minute  portion  of  muriatic  acid  left 
remaining  in  the  corks,  w^hich  might  render  them  unfit  for  use  for 
many  purposes,  but  this  is  not  the  case.  The  acid  contamination  is  so 
slight  as  to  be  of  little  consequence,  not  sufficient  to  be  objectionable 
for  all  the  purposes  for  which  such  corks  would  be  likely  to  be  used. 
Of  course,  no  pharmacist  would  think  of  using  any  but  new  and  per- 
fectly pure  and  clean  corks  for  all  delicate  solutions,  such  as  nitrate  of 
silver,  he. 
Muriatic  acid,  properly  diluted,  forms  an  excellent  bleaching  sub- 
stance, and  the  pharmacist  may  avail  himself  of  its  use  with  advantage 
for  many  purposes.  There  is  no  better  or  more  convenient  article  for 
removing  stains  from  the  hands  and  from  mortars  than  this  acid. 
The  store  towels,  which  so  often  become  stained,  and  present  a  very 
untidy  and  unsightly  appearance  even  after  they  have  been  washed,  may 
be  greatly  improved,  if  not  entirely  restored  to  their  original  color,  by 
immersing  them  for  a  few  minutes,  after  they  have  been  thoroughly 
washed,  in  a  mixture  of  one  part  of  muriatic  acid  to  nineteen  parts  of 
boiling  water,  and  then  thoroughly  rinsing  them  in  clean  water.

The  Pharmaceutical  Exhibition  in  Boston.  By  A.  W.  Miller,  M.  D. — 
The  twenty-third  meeting  of  the  American  Pharmaceutical  Association,  in  Boston, 
was  graced  by  a  superb  exhibition  of  drugs,  chemicals,  pharmaceutical  products  and 
druggists'  sundries,  which  was  quite  worthy  of  being  regarded  as  an  appropriate 
prelude  to  that  which  we  have  a  right  to  expect  at  the  approaching  Centennial.  By 
universal  consent  this  was  the  most  brilliant  and  instructive  display  that  we  have  so 
far  had  of  these  articles.  Our  Boston  friends  had  planned  everything  so  carefully^ 
and  had  provided  all  the  requisites  and  adjuncts  necessary  or  even  desirable  to 
enrich  the  splendors  of  the  display  in  so  liberal  and  pains-taking  a  manner, 
that  the  whole  affair  passed  off  as  smoothly  and  harmoniously  as  if  it  had  been 
devised  by  eminent  military  talent.  The  committee  in  charge  of  the  exhibition 
richly  deserve  the  warmest  thanks  for  their  most  admirable  arrangements,  and  the 
thorough  and  systematic  manner  in  which  they  executed  the  arduous  labors  imposed 
upon  them. 
The  exhibition  was  held  in  Encampment  Hall,  located  in  one  of  the  upper  stories 
of  the  new  and  beautiful  Odd  Fellows'  Building.  Although  the  dimensions  of  this 
hall  aie  quite  respectable,  it  was  found  to  be  insufficient,  so  that  a  large  proportion 
of  the  goods  had  to  be  arranged  in  the  corridor  leading  to  it.    Encampment  Hall
