leaves,  etc.,  for  distilled  waters,  I  have  myself  practically  car- 
ried it  out  with  great  success,  having  kept  flowers  for  two  years, 
and  on  opening  them,  found  not  only  the  perfume  natural, 
but  the  structure  of  the  flowers  without  the  least  disorganization. 
The  process  proposed  as  a  substitute  for  the  ordinary  one  of 
enfleurage  by  fats,  of  course  I  merely  throw  out  as  a  suggestion, 
as  it  could  only  be  practically  put  to  the  proof  at  some  place 
where  the  flowers  are  cultivated  extensively.  The  great  num- 
ber of  men  and  women  employed  in  the  present  process  at 
Grasse  and  Cannes  would  point  out  that  a  great  saving  would 
be  made  both  in  time  and  money  by  a  method  similar  to  the 
above.  Another  object  is  that  although  there  are  large  growers 
at  the  above-named  localities,  the  mass  of  the  flowers  are  grown 
by  cottagers,  and  collected  from  them  by  commissionnaires.  In 
the  glycerine  plan  the  flowers  could  be  placed  in  perfect  safety 
as  brought  in,  and  by  this  means  all  danger  from  heating  by 
fermentation  is  thrown  out  of  consideration.  I  have  extracted 
on  the  small  scale,  and  by  the  above  means,  the  aromata  from 
Heliotr opium  grandiflorum,  Cheiranthus  Cheiri,  and  others.

ON  PREPARATIONS  OF  CINCHONA. 
By  Alfred  B.  Taylor. 
"  Is  there  an  eligible  means  by  which  the  medicinal  matter  of  cinchona 
maybe  held  in  a  permanent  solution  without  deposition  of  cinchotannates 
or  cinchonic  red  ?" 
In  attempting  to  answer  this  query,  I  supposed  the  intent 
of  it  to  be  the  finding  a  solvent  which  shall  retain  all  the  reme- 
dial properties  of  cinchona  in  their  natural  condition  or  com- 
bination, and  without  decomposition. 
From  the  peculiar  solvent  properties  of  glycerin,  it  was 
thought  that  some  combination  of  this  substance  with  alcohol 
or  sugar  might  answer  the  purpose,  and  accordingly  the  follow- 
ing experiments  were  instituted : 
A  tincture  of  cinchona  was  prepared,  of  the  ordinary  strength, 
using  a  menstruum  composed  of  two  parts  of  alcohol,  one  part 
of  glycerin  and  one  part  of  water.    After  standing  for  two  or
