'^'"iviay'iss!?""  }    Fluid  Extvacts  of  the  New  Pharmacopoeia.  239 
the  Committee  of  Revision  acted  wisely  in  dismissing  this  evidently 
superfluous  preparation. 
ExTRACTUM  HeliajsTHEMi  Fluidum. — Fluid  Extract  of  Frost- 
■wort. — For  tliis  preparation  a  menstruum  composed  of  one  part  of 
al(!ohol  and  two  parts  of  water,  was  recommended ;  a  sample  thus  pre- 
pared in  December,  1879,  now  contains  a  rather  large  precipitate,  but 
is  otherwise  in  good  condition ;  but  frostwort  having  been  dismissed 
from  the  Pharuiacopoeia,  no  preparations  of  it  were  adopted. 
ExTRACTUM  JuNiPERi  FiJJiDUM. — Fluid  Extract  of  Juniper. — For 
this  preparation  the  juniper  was  recommended  to  be  in  number  eight 
powder,  and  diluted  alcohol  the  menstruum  to  be  used ;  a  sample  thus 
prepsrred  in  January,  1880,  now  contains  only  a  moderate  precipitate, 
but  there  is  also  a  considerable  quantity  of  soft,  brown,  resinous  matter 
on  the  sides  of  the  bottle  above  the  fluid  extract;  in  other  respects  the 
preparation  has  not  deteriorated,  the  odor  and  taste  remaining  as  aro- 
matic, and  sweet  as  when  first  prepared.  The  specific  gravity  of  this 
imple  of  fluid  extract  is  1*1 15,  and  the  weight  of  dry  residue  from 
he  juniper  was  fifty-eight  per  cent. 
Juniper,  if  fresh  and  of  good  quality,  is  very  difficult  to  percolate 
f  finer  than  number  eight  powder,  and  to  prove  that  so  coarse  a 
powder  may  be  exhausted,  another  sample  of  the  fluid  extract  was 
prepared  at  the  same  time,  using  the  entire  fruit,  carefully  selecting 
only  such  as  were  unbroken  ;  this  sample  now  contains  about  the  same 
uantity  of  precipitate  as  the  other,  but  instead  of  the  brown  matter 
in  the  upper  part  of  the  bottle,  there  is  a  very  thin  coating  of  a  bright 
green  color;  the  odor  and  taste  are  as  well  preserved  as  in  the  other 
Sample,  the  specific  gravity  is  1'066,  and  the  weight  of  dry  residue 
"was  sixty-one  per  cent. 
Although  juniper  may  not  be  a  very  important  remedial  agent,  it  is 
■considerably  used  by  physicians,  and  so  elegant  and  permanent  a  pre])a- 
'ation  as  this  fluid  extract  might  well  have  been  made  oflicinal. 
ExTRACTUM  Lapp^  Fluidum. — Fluid  Extract  of  Burdock. — For 
this  preparation  a  menstruum  composed  of  one  part  of  alcohol  and 
two  parts  of  water,  was  recommended ;  a  sample  thus  prepared  in 
December,  1879,  now  contains  only  a  slight  precipitate,  and  is  other- 
wise entirely  without  change.  Burdock  does  not,  how^ever,  appear  to 
of  sufficient  medicinal  value  or  employment  to  require  any  officinal 
preparations  thereof.
