Moisten  the  cantharides  with  a  small  portion  of  the  ether,  and  pack 
in  a  conical  percolator.  Then  pour  on  the  balance  of  the  ether,  mixed 
with  4  fluidounces  alcohol,  and  follow  with  enough  alcohol  to  recover 
16  fluidounces,  in  which  dissolve  the  gun  cotton. 
These  collodions  can  be  used  as  substitutes  for  many  of  the  officinal 
plasters,  having  the  advantage  of  occupying  a  small  bulk,  ready  adapt- 
ability to  any  surface,  and  powerful  therapeutic  action. 
I  have  endeavored,  as  far  as  possible,  to  give  some  practical  infor- 
mation on  a  branch  of  pharmacy  of  which  comparatively  little  is 
known.  The  subject  is,  I  think,  an  important  one,  since  gun  cotton 
and  collodion  occupy  a  high  position  in  both  medicine  and  the  useful 
arts,  and  to  its  elaboration  and  useful  application  too  much  study  can- 
not be  devoted. 
CITRATE  OF  IRON  AND  BISMUTH. 
A  New  Remedy  for  Dyspepsia,  &c. 
By  Charles  Rice. 
Although  I  call  this  preparation  new,  it  has  been  in  use  for  several 
years  in  the  public  hospitals  and  dispensaries  of  this  city,  and  also  in 
private  practice,  and  has  acquired  the  reputation  of  being  one  of  the 
most  prompt  and  valuable  remedies  at  present  known  for  gastric  dis- 
turbances, depending  upon  an  abnormal  or  defective  digestion  gene- 
rally, and  particularly  so  for  the  gastric  intolerance  of  consumptive 
patients.  Its  action  is  often  so  prompt  that  one  full  dose  has  in  many 
instances  afforded  immediate  relief. 
Being  requested  some  years  ago  to  devise  a  liquid  preparation  con- 
taining bismuth  and  iron  (at  that  time  intended  for  use  in  some  other 
complaints),  I  finally,  after  various  trials,  adopted  the  following  for- 
mula, which  I  have  followed  ever  since :
