THE  FOLLOWING  ARE  ABSTRACTS  OF  SOME  OF  THE 
PAPERS  : 
The  Formation  of  Precipitates  by  Solutions  of  Iodides  in 
Enzyme  Elixirs. 
By  H.  C.  Blair. 
The  author  calls  attention  to  the  fact  that  solutions  of  the  iodides 
and  also  of  the  bromides  produced  precipitates  in  compound  diges- 
tive elixir  and  essence  of  pepsin,  and  on  standing  for  some  time, 
such  solutions  become  darker  in  color  and  lose  their  agreeable  odor 
and  taste.  He  advises  that  as  these  elixirs  are  very  often  given 
merely  as  vehicles,  a  line  of  palatable,  non-medicinal  elixirs  be  offered 
to  the  physician  for  this  purpose. 
Beef  Extracts. 
By  H.  A.  Bradshaw. 
Comparative  analyses  are  given  of  a  number  of  brands  of  beef 
preparations,  showing  the  presence  of  potassium  nitrate  resulting 
from  the  use  of  cured  meat  instead  of  fresh  meat  in  making  the 
preparations. 
The  Estimation    of  Acetanilid,  Phenacetin,   Heroin,  and 
Heroin  Hydrochloride. 
By  Edward  S.  Rose  and  Maxwell  M.  Becker. 
A  simple  and  satisfactory  process  for  the  estimation  of  any  one 
of  these  four  substances  is  given  by  the  use  of  sulphuric  acid  and 
distillation,  the  liberated  acetic  acid  being  titrated.  Comparative 
figures  are  given,  showing  the  accuracy  of  the  process  when  used 
with  mixtures  of  known  composition. 
Improved  Elixir  of  Terpin  Hydrate. 
By  P.  Henry  Utech. 
The  author  states  that  the  objections  to  the  U.S. P.  and  to  the 
N.F.  elixirs  are,  first,  their  exceptionally  high  alcoholic  content,  and 
second,  the  minimum  amount  of  medicament.  He  suggests  the 
following  formula:  Terpin  hydrate,  powdered,  256  grains;  acetic 
acid,  80  minims ;  Tr.  sweet  orange  peel,  2  fluiddrachms ;  alcohol, 
8  fluidounces ;  glycerin,  4  fluidounces ;  aromatic  elixir,  q.  s.,  16 
fiuidounces.  He  states  that  this  preparation  will  not  precipitate, 
even  when  exposed  to  freezing  temperature,  and  that  it  can  be 
administered  with  resinous  tinctures  without  precipitation.
