pharmacist  would  do  well,  when  he  does  find  a  good  article,  to  make 
up  a  considerable  quantity  of  the  fluid  extract. 
ExTRACTUM  Erythroxyli  Fi.uiDUiM. — Fluid  Extract  of  Ery- 
throxylon. — This  is  a  newly  introduced  preparation,  it  is  not  probable 
that  the  officinal  English  title  will  supercede  the  name  of  fluid  extract 
of  coca,  by  which  this  preparation  is  commonly  known.  The  Phar- 
macopoeia directs  diluted  alcohol  as  the  menstruum,  and  the  Philadel- 
pliia  College  of  Pharmacy  recommended  the  same.  A  sample  of  the 
fluid  extract  prepared  in  December,  1879,  remains  in  good  condition,, 
with  only  a  slight  precipitate,  and  a  very  small  quantity  of  waxy 
matter  on  the  upper  part  of  the  bottle. 
ExTRACTUM  Eucalypti  Fluidum. — Fluid  Extract  of  Euca- 
lyptus.— This  is  also  one  of  the  new  fluid  extracts.  The  Pharma- 
copoeia directs  alcohol  to  be  used  in  its  preparation,  and  the  Philadel- 
phia College  of  Pharmacy  recommended  the  same  menstruum.  A 
sample  thus  made  in  December,  1879,  remained  without  change  for 
some  time,  but  it  now  contains  a  moderate  quantity  of  sediment,  and 
above  this  appears  a  large  quantity,  about  one-fourth  of  the  bulk  of 
the  fluid  extract,  of  greenish,  somewhat  gelatinous,  separated  matter,, 
thus  affording  sufficient  evidence  that  alcohol  is  not  the  proper  men- 
struum for  this  preparation.  Another  sample  was  made  at  the  same 
time  as  the  first  one,  with  a  menstruum  composed  of  three  parts  of 
alcohol  and  one  part  of  Avater,  this  soon  deposited  a  moderate  precipi- 
tate, but  no  further  change  has  occurred,  and  this  sample  now,  after 
three  years  have  elapsed,  possesses  all  the  characteristics  of  a  good  fluid 
extract ;  this  menstruum  is  therefore  recommended  as  being  decidedly 
better  for  eucalyptus,  than  alcohol  alone. 
ExTRACTUM  EuPATORii  Fluidum. — Fluid  Extract  of  Ewpatorium,. 
— This  is  one  of  the  new  fluid  extracts.  The  Pharmacopoeia  directs 
diluted  alcohol  as  the  menstruum,  the  Philadelphia  College  of  Phar- 
macy recommended  one  part  of  alcohol  and  two  parts  of  water ;  a 
sample  thus  prepared  in  December,  1879,  now  contains  only  a  mod- 
erate deposit,  and  the  liquid  portion  is  perfectly  transparent,  and  of  a 
deep  red  color  in  thin  layers  ;  it  has  acquired  a  very  peculiar  odor,, 
and  has  apparently  undergone  some  change.  The  officinal  menstrunm 
is  no  doubt  the  best  for  this  not  very  important  preparation. 
ExTRACTUM  FRANGULiE  Fluidum. — Fluid  Extract  of  Frangula. 
— This  is  also  a  newly  introduced  preparation.  The  Pharmacopoeia 
directs  a  menstruurn  composed  of  one  part  of  alcohol  and  two  parts  of
