OLEORESINA.  ZINGIBERIS. 
From  Jamaica  ginger,  in  powder.    No.  60. 
Remarks. — Of  these  Oleoresins,  those  of  capsicum,  cubebs, 
pepper,  cloves,  lupulin,  savin  and  ginger,  possess  decided  merit. 
That  of  cardamom  is  a  liquid,  consisting  of  one-third  volatile  oil 
and  two-thirds  fixed  oil,  with  but  little  resinous  matter.  The  male 
fern  is  used  in  Europe  and  occasionally  here.  The  Xanthoxylum 
as  used  by  the  Eclectics  is  prepared  by  another  formula.  The  list 
might  be  much  extended  but  even  that  submitted  is  longer  than 
will  be  accepted.  The  oleoresin  of  savin  incorporates  easily 
with  resin  cerate,  and  affords  the  most  elegant  form  of  savin 
cerate  yet  suggested. 
In  conclusion  it  may  be  again  remarked,  that  the  formulae  are 
all  such  as  the  Pharmaceutist  may  practice  in  the  shop ;  they  do 
not  involve  much  expenditure  of  apparatus,  and  when  attention 
is  given  to  the  division  of  the  powders  and  the  manipulation  of 
the  percolation  as  directed,  the  result  will,  it  is  believed,  gen- 
erally give  satisfaction.  It  is  quite  possible  that  some  of  them 
by  keeping  a  length  of  time  will  deposit  sediment,  the  result  of 
a  disturbance  in  the  balance  of  the  solubilities.  This  may  be 
expected,  but,  except  in  very  few  instances,  it  has  no  influence 
on  the  medicinal  power  of  the  extract. 
It  is  proper  before  leaving  the  subject  to  extend  a  caution  in 
reference  to  such  of  the  above  formulae  as  are  suggested  as  sub- 
stitutes for  the  present  officinal  fluid  extracts  that  differ  in 
strength  or  composition  from  them — that  they  should  not  be 
used  until  sanctioned  by  authority,  yet  the  improved  manipula- 
tion may  be  applied  where  it  does  not  alter  the  character  of  the 
preparations.

ON  A  NEW  MODE  OF  PREPARING  SOME  SYRUPS. 
By  Jno.  M.  Maisch. 
The  directions  of  the  Pharmacopoeia  for  a  number  of  syrups, 
require  an  exhaustion  of  the  crude  material  by  diluted  alcohol ; 
the  tincture  is  then  evaporated  to  drive  off  the  alcohol,  the 
residue  diluted  by  water,  sugar  is  added,  and  heat  applied  to
