The  mode  of  operation  is  essentially  the  same  as  with  the  ferric 
solution.  It  should  be  allowed  to  stand  about  12  hours  before 
filtration.  It  is  of  a  deep  reddish  brown  color,  miscible  with  water, 
of  a  sweetish,  ferruginous  taste  and  acid  reaction  ;  sp.  gr.  I- 160.  It 
contains  2  5  grs.  of  the  salt  in  one  dram. 
It  is  not  the  place  of  the  pharmacist  to  dwell  upon  any  possible 
therapeutical  value  of  the  salt  or  its  solution,  yet  like  all  other  iron 
compounds  it  may  be  worthy  of  a  trial,  which  it  apparently  never 
received. 
To  the  query:  What  is  thedest  formula  for  making  the  solution? 
no  positive  answer  can  be  given.  The  three  methods  described  all 
yielded  solutions,  which  so  far  have  remained  stable.  If  the  solu- 
tion is  required  to  be  ferrous,  naturally  the  formula  for  the  same 
should  be  used.  For  the  ferric  it  must  be  said,  that  the  solution 
prepared  directly  from  the  salt  presents  a  more  attractive  appear- 
ance, but  succinate  of  iron  is  seldom  found  in  a  retail  pharmacy.  If 
not  obtainable,  the  other  method  may  be  satisfactorily  employed. 
Perhaps  a  more  positive  answer  can  be  given,  on  examining  the 
solutions  after  allowing  them  to  stand  for  some  time,  when  any  pos- 
sible change  may  be  noted.  Which  is  the  best  formula,  we  are  at 
present  not  able  to  say.

III.  THE  BERRIES. 
Professor  Dragendorff's  scheme  of  plant  analysis  was  used  in  the 
following  investigation  on  the  berries  of  Solanum  carolinense,  which 
had  almost  been  completed,  when  a  paper  on  the  same  subject 
appeared  in  the  Amer.  Jour.  Pharm.,  1 891 ,  p.  126. 
In  the  first  place,  an  analysis  of  the  fresh  and  bruised  berries  was 
made.  Petroleum  ether  and  ether  extracted  small  quantities  of  an 
ethereal  and  of  fatty  oil,  the  former  having  a  rather  suffocating 
odor. 
Alcohol  extracted  the  moisture,  became  hydrated,  and  so  dis-
