The  Fluid  Extracts  of  Tilden  &  Co. — In  our  last  number  we 
acknowledged  the  reception  of  twenty-one  specimens  of  Tilden  &  Co/s 
fluid  extracts,  then  too  late  for  notice.  Since  that  time,  two  months,  they 
have  been  kept  in  a  closet  at  the  temperature  of  the  store  with  the  mercury 
varying  from  70°  to  94°,  with  no  means  taken  to  prevent  its  influence. 
These  preparations  are  said  to  be  made  according  to  the  Pharmacopoeia, 
when  officinal,  and  in  several  instances  according  to  formulae  published  in 
this  journal  when  not  recognized  by  authority,  whilst  some  are  made  by 
the  judgment  of  the  manufacturers,  always,  in  such  cases,  being  of  the 
strength  of  1  oz.  to  f^i.  They  are  put  up  in  panelled  bottles,  holding  about 
four  fluid  ounces  labelled  and  wrapped. 
Belladonna,  Hyoscyamus  and  Lobelia.  These  fluid  extracts  may  be 
noticed  together.  They  are,  when  shaken,  dark  green  fluids,  owing  to  the 
chlorophylle  they  contain,  the  two  first  appearing  evidently  to  be  made 
from  the  recent  plant.  The  Belladonna  and  Hyoscyamus  smell  strongly  of 
the  recent  plants  when  bruised,  and  have  their  peculiar  taste  well  developed. 
Although  made  from  the  green  plants,  the  proportion  is  a  fluid  ounce  to  an 
ounce  of  the  dried  plant,  which  is  ascertained  by  drying  a  small  quantity 
of  the  herb  and  ascertaining  its  loss,  and  then  using  a  corresponding  quan- 
tity of  the  recent  plants.  Being  concentrated  in  vacuo  and  preserved  with 
a  little  alcohol,  these  fluid  extracts  appear  to  be  fully  charged  with  the  sen- 
sible and  medicinal  properties  of  these  drugs. 
Rhubarb,  Senna,  Rhubarb  and  Senna,  Senna  and  Taraxacum,  Senna 
and  Spigelia,  and  Buckthorn. — These  appear  to  be  well  made.  The  Rhu- 
barb, while  it  has  the  proper  odor  and  taste,  is  rather  more  fluid  than  it 
usually  appears.  So  much  depends  on  the  choice  of  the  root  that  it  is  a 
difficult  matter,  obscured  as  the  taste  is  with  aromatics,  to  judge  with  ,cer-
