which  sometimes  amounted  to  one-third  of  what  the  concentrated  solution 
should  represent.  Attention  was  directed  to  the  occurrence  of  water  in  high- 
grade  carbolic  acid  which  was  sold  as  official.  lowered  fusing  and  boiling 
points  were  mentioned  as  indications  of  its  presence. 
Examination  of  ten  samples  of  reduced  iron,  including  both  gray  and  black, 
showed  considerable  variation.  None  contained  sufficient  metallic  iron  to  be 
official,  although  several  were  so  labelled. 
Additional  experiments  with  Datura  Stramonium  were  contributed  by- 
Alfred  R.  L.  Dohme,  who  drew  the  following  conclusions  : 
(1)  That  the  stems  of  Datura  stramonium  contain  more  alkaloid  than  the 
leaves. 
(2)  That  the  plant  Datura  stramonium  gathered  in  June  contains  less  alka- 
loid than  that  gathered  in  July  and  August. 
(3)  That  Keller's  method  extracts  more  alkaloid  from  the  drug  than  Dragen- 
dorff  s  method  does. 
This  gentleman  also  submitted  a  discourse  on  the  relative  alkaloidal  value 
of  two  kinds  of  ipecac  root,  known  as  "  fancy  "  and  "  wiry."  The  former  is 
the  annulated  variety  and  is  the  root  proper,  while  the  latter  is  that  part  of  the 
root  which  merges  into  the  stem.  In  a  given  weight,  the  "  wiry  "  shows  more 
cortex,  which,  being  the  seat  of  the  alkaloid,  makes  this  variety  richer  in  eme- 
tine than  the  "  fancy." 
In  another  paper  the  same  author  answered  the  query  :  What  is  the  quality 
of  the  reduced  iro?i  dispensed  by  pharmacists  ? 
After  examining  numerous  samples  of  both  black  and  gray,  the  latter  of 
which  usually  contains  the  larger  amount  of  metallic  iron,  he  reported  that  the 
article  usually  sold  is  not  of  standard  quality  on  account  of  the  presence  of  con- 
siderable oxide  and  sulphide.

Improved  working  formula,  number  27,  National  Formulary,  was  the  sub- 
ject of  a  paper  by  Samuel  C.  Davis,  who  has  found  the  following  method  satis- 
factory for  the  preparation  of  Elixir  of  Valerianate  of  Ammonium.
