Mr.  J.  U.  Lloyd  presented  a  paper  on  spirit  of  nitrous  ether  (see  page  503)  5  also 
one  on  citrate  of  iron  and  ammonium.  To  prepare  the  latter  it  is  proposed  to  pre- 
pare 16  fluidounces  of  solution  of  neutral  citrate  of  ammonium  from  8  ounces  of 
citric  acid  and  sufficient  ammonia  water;  also  a  solution  of  citrate  of  iron  from  4 
ounces  of  citric  acid  saturated  with  freshly-precipitated  oxide  of  iron,  and  to  mix  this 
with  5  fluidounces  of  solution  of  ammonium  citrate,  after  which  it  is  to  be  evapor- 
ated and  scaled  in  the  usual  manner. 
A  paper  by  the  same  author  on  citrate  of  iron  and  quinia  was  read,  advocating  a 
change  in  the  officinal  directions  so  as  to  precipitate  the  quinia  at  a  temperature  of 
5o°F.  (see  "Amer.  Jour.  Phar."  1876,  p.  107),  and  for  the  purpose  of  rendering  the 
salt  soluble  but  not  deliquescent,  to  add  to  the  ice-cold  solution  of  citrate  of  iron 
and  quinia,  very  slowly  and  with  constant  stirring,  a  sufficient  amount  of  ammonia 
without  permanently  precipitating  the  alkaloid. 
A  change  in  the  formula  for  tartrate  of  iron  and  potassium  was  proposed  by  the 
same  author,  as  follows  :  The  hydrated  oxide  of  iron  obtained  from  9  parts  of  solu- 
tion of  tersulphate  of  iron  is  mixed  with  32  parts  of  water  and  4  parts  of  cream  of 
tartar,  heated  and  stirred  until  the  ferric  oxide  is  dissolved,  and  filtered  from  the 
undissolved  cream  of  tartar.  On  setting  the  filtrate  aside  in  a  cool  place  for  about 
a  day,  a  heavy  brickdust-colored  precipitate  will  be  observed,  which  is  dissolved  by 
the  cautious  addition  of  ammonia,  after  which  the  solution  is  evaporated  and  scaled. 
The  salt  contains  a  small  amount  of  citrate  of  ammonium,  has  a  slight  sweetish  taste 
and  is  readily  soluble  in  half  its  weight  of  cold  water. 
Mr.  Lloyd  also  read  a  paper  on  hydrated  oxide  of  iron,  advocating  the  addition 
of  the  word  "cold"  wherever  water  is  mentioned  in  the  formula  ;  he  also  suggests 
to  increase  the  cold  water  for  diluting  the  iron  solution  from  two  to  four  pints,  to 
mix  the  drained  precipitate  with  16  pints  of  cold  water,  strain  again  and  to  repeat 
this  operation.    The  resulting  preparation  should  be  perfectly  soluble  in  citric  acid. 
A  lengthy  report  on  fluid  extracts  was  read  by  Professor  Diehl ;  it  is  a  continua- 
tion of  the  one  presented  last  year,  and  discusses,  among  other  points,  the  strength 
of  fluid  extracts  obtainable  by  simple  and  by  fractional  percolation.  The  paper  is 
not  adapted  for  making  a  brief  abstract. 
On  motion  of  Dr.  Ross,  amended  by  Prof.  Diehl,  it  was  resolved  that  the  report 
on  the  Pharmacopoeia,  presented  at  this  meeting,  be  published  in  cheap  pamphlet 
form,  provided  the  expenses  of  the  same  be  defrayed  by  the  various  Colleges  of 
Pharmacy  and  Pharmaceutical  Associations  of  the  United  States. 
The  Executive  Committee  gave  notice  that  24  candidates  had  applied  for  mem- 
bership. 
Mr.  Wellcome  read  a  paper  on  the  cinchonas  of  South  America,  and  exhibited  a 
large  number  of  specimens  of  bark  collected  by  him  during  a  recent  trip  to  Peru. 
The  Association  adjourned  until  3J  o'clock. 
Fifth  Session,  Thursday  Afternoon,  September  nth.— After  the  approval  of  the 
minutes,  22  of  the  candidates,  proposed  at  the  fourth  session,  were  balloted  for  and 
elected,  Messrs.  Wells  and  Good  acting  as  tellers. 
A  paper  by  Mr.  C.  S.  Hallberg  was  read,  on  the  galenical  preparations  of  the 
Pharmacopoeia  and  a  new  form  of  medication  termed  saccharated  extracts.  This
