Nos.  4,  5  and  12  agree  neither  with  the  old  strength  nor  with  the 
new,  but  come  within  the  limits  (2*3  to  3*3  grains  to  ti'ie  fluidounce) 
assigned  by  Mr.  Parsons  to  laudanums  probably  made  from  moist 
opium. 
Thus,  of  the  16  samples  of  tincture  of  opium  we  have  7  answering 
nearly  or  quite  the  requirements  of  the  U.  S.  P.,  1880,  4  meeting 
those  of  the  U.  S.  P.,  1870,  2  somewhat  below  this  standard,  and  3 
containing  such  a  small  percentage  of  morphia  that  they  are  open  to 
the  suspicion  of  having  been  intentionally  made  of  low  morphia 
strength. 
In  every  case,  however,  where  the  label  contained  the  letters 
U.  S.  P.,  or  the  statement  that  the  laudanum  was  made  according  to 
the  U.  S.  P.,  1880,  it  was  found  to  contain  between  5  and  6  grains  of 
morphia  to  the  fluidounce. 
The  number  of  samples  is  not  large,  and  they  were  obtained  only 
from  New  York  and  Boston,  therefore  it  is  hardly  safe  to  draw  general 
conclusions  from  the  assays ;  but  as  these  samples  were  received  in 
June,  1883,  at  least  seven  months  later  than  those  assa^^ed  by  Mr. 
Parsons,  and  after  sufficient  time  had  elapsed  for  the  new  standard  to 
be  adopted,  it  may,  perhaps,  not  be  quite  useless  to  give  the  results.

EXTRACT  OF  MALT. 
By  J.  U.  Lloyd. 
Head  at  the  Sixth  Session  of  the  Thirty-first  Annual  Meeting  of  the  Amer- 
ican Pharmaceutical  Association. 
When  substances  of  this  kind  were  introduced  some  five  years  ago, 
we  were  induced  by  the  demand  created  to  make  a  preparation  of  malt. 
In  looking  at  the  matter  it  then  seemed  to  us  that  the  desideratum 
was  a  pharmaceutical  one  which  should  embody  the  soluble  con- 
stituents of  well  malted  barley.  We  therefore  arrived  at  the  conclu- 
sion that  there  was  little  if  any  necessity  for  a  deviation  from  the 
regular  line  of  fluid  extracts,  although  the  process  for  making  malt 
extract  in  Germany  resulted  in  a  substance  of  the  consistence  of  thick 
honey.  Our  view  of  the  subject  has  not  been  changed.  The  most 
practical  and  feasible  process  for  extracting  the  desirable  principles 
from  malt  in  our  opinion  is  that  of  percolation.    The  product  repre-
