properties.  Any  other  incidental  virtues  which  it  may  be  imagined  to 
contain  must  be  simply  negative. 
Like  all  similar  preparations  of  tar,  the  wine  of  tar,  as  above  pre- 
pared, deposits  on  standing  more  or  less  inert  oxidized  resinous  matter, 
and  requires  to  be  filtered  occasionally,  which  restores  it  to  the  appear- 
ance presented  by  the  samples.

LIQUOR  POTASSII  CITRATIS. 
BY  AUG,   HOHL,   PH.  G. 
[Read  at  the  Pharmaceutical  Meeting,  April  loth.) 
The  great  trouble  with  this  preparation,  so  much  used  in  medicine,  is 
to  keep  it  fresh  and  clear.  Having  tried  various  formulas,  old  and 
new,  and  finding  that  the  solution  will  always  turn  turbid  and  flocculent 
in  a  short  time,  I  offer  the  following,  which  is  not  liable  to  this  objec- 
tion : 
I.  R.  Citric  acid,        .        .       .       5i    2.  R.  Bicarbonate  of  potassium,    .  ^xi 
Distilled  water       .  f^viii  Distilled  water,         .        .  f^viii 
Dissolve  and  filter.  Dissolve  and  filter. 
Two  solutions  are  thus  obtained  ready  for  use  ;  and  when  liq. 
potass,  citr.  is  ordered,  all  that  is  necessary  is  to  mix  equal  parts  of  the 
two,  allow  it  to  effervesce,  and  the  preparation,  fresh  and  clear  as  crys- 
tal, is  ready  for  use. 
The  above  quantities  are  double  those  of  the  "U.  S.  Pharmacopceia." 
SUPPOSITORIES. 
BY   A,   M.   KNOWLSON,  TROY,   N.  Y. 
I  have  read  with  interest  the  articles  of  Messrs.  Kennedy  and  Kem- 
ble  on  suppositories,  in  the  "Amer.  Journ.  Pharm."  for  the  months  of 
February  and  March,  respectively,  and  would  crave  a  small  space  in 
your  valuable  Journal  to  say  a  word  on  the  same  subject ;  audi  alteram 
partem.  Each  of  the  articles  referred  to  strongly  objects  to  the  mould- 
ing of  suppositories  by  a  machine  ;  and  one  rather  pointedly  intimates 
that  the  great  end  in  view  of  the  pharmacist  who  prepares  them,  is  sim- 
ply to  turn  off  a  great  quantity  of  elegant  preparations,  and  at  a  large 
profit  to  the  manufacturer,  without  any  regard  to  the  poor  sufferer  who 
is  to  use  them.
