of  sulphuric  acid  and  nitrate  of  potash  (or  their  equivalents).  This  immediately 
attacks  the  shadows,  or  exposed  portious  of  the  silver  surface,  while  the  copper 
parts  from  the  electrotype  bath  are  not  affected.  After  etching  to  the  required 
depth,  the  copper  deposit  may  be  removed  by  aqua  regia,  leaving  a  finely 
etched  image  on  the  silver  plate.  To  engrave  on  steel,  copper,  etc.,  it  is  first 
necessary  to  coat  the  surface  with  pure  silver,  after  which  the  process  is  sub- 
stantially the  same  as  that  above  described,  with  some  modifications  of  the 
acids  or  combinations  used,  according  to  the  nature  of  the  metal  employed. —

Pharmaceutical  Association  convened  at  the  Library  Room  of  the  Portland 
Army  and  Navy  Union,  Tuesday,  July  16,  1872,  at  3.45  P.M.  The  Secretary, 
Mr.  C.  Way,  being  absent,  on  account  of  indisposition,  Herschell  Boynton  was 
chosen  Secretary  pro  tern.  The  minutes  of  the  last  meeting  were  read  and 
approved.  After  the  election  of  new  members,  the  election  of  officers  was 
postponed  until  the  next  meeting.  The  report  of  the  Treasurer  was  then  read 
and  accepted,  after  which  the  President  read  his  annual  address,  which,  on 
motion,  was  ordered  to  be  published  in  full  in  the  forthcoming  book  of  Proceed- 
ings of  the  Association.  Mr.  Schlotterbeck  then  read  a  paper  upon  purified 
extract  of  liquorice,  which  was  accompanied  with  specimens,  and  was  referred 
to  the  Committee  of  Publication.  The  Treasurer  was  authorized  to  deposit 
funds  lying  unused  in  his  hands,  in  the  savings  bank,  according  to  the  exercise 
of  his  best  discretion.  Portions  of  letters  from  the  gentlemen  appointed  dele- 
gates to  the  Maine  Pharmaceutical  Association  from  the  Vermont  Pharma- 
ceutical Association,  were  then  read,  in  which  the  writers  expressed  their 
regret  at  their  inability  to  be  present  at  the  meeting,  their  sympathy  and 
cordial  co-operation  in  the  object  aimed  at,  and  the  salutations  of  the  Green 
Mountains  to  the  Pine  Trees.  The  President  was  empowered  to  accredit 
delegates  to  attend  the  meeting  at  Montpelier. 
The  subject  of  change  of  time  for  the  annual  meeting  came  up,  and  it  was 
voted  to  test  the  matter  experimentally,  and  to  adjourn  to  the  third  Tuesday 
of  October  next  ensuing.  With  a  vote  of  thanks  to  the  P.  A.  and  N.  U.  for 
the  use  of  their  beautiful  and  quiet  room,  the  Association  adjourned.
