with  fresh  boiling  alcohol.  The  caryophylline  thus  purified, 
and  perfectly  white,  weighed,  when  added  to  that  previously 
obtained,  1  ounce  and  5  drachms. 
A  portion  of  the  cloves  which  had  been  submitted  for  the 
fourteenth  time  to  the  process  of  distillation,  and  had  then  been 
dried  in  the  air,  were  treated  in  the  tin  vessel  with  boiling  alco- 
hol, and  rapidly  placed  on  a  filter.  The  brown  solution,  upon 
cooling,  deposited  some  caryophylline  in  cloudy  flocks,  but  its 
quantity  was  inconsiderable ;  and  when  it  is  requisite  to  prepare 
the  substance  in  larger  quantity,  the  process,  just  described,  of 
driving  it  over  with  water  is  certainly  the  most  to  be  recom- 
mended, and  the  cheapest. 
If  one  had  to  operate  upon  a  considerable  quantity  of  cloves, 
as  50  pounds  or  more,  it  would  probably  be  the  simplest  way  of 
all,  after  obtaining  the  oil,  to  transfer  the  contents  of  the  still 
while  yet  hot  to  a  coarse  strainer,  and  when  drained  again,  to 
boil  them.  The  mixed  decoctions  might  be  allowed  to  subside 
for  some  days  in  large  glass  bottles,  the  clear  supernatant  liquor 
poured  off  from  the  sediment,  and  this  latter  then  washed  with 
cold  water  several  times.  Having  been  thrown  upon  a  filter 
and  dried,  it  might  then  be  treated  with  alcohol  and  animal 
charcoal  as  already  described. — Lon.  Pharm.  Journ,  Sep.  1859,

MANUFACTURE  OF  OTTO  OF  ROSES. 
At  a  meeting  of  the  London  Pharmaceutical  Society,  Oct.  5, 
1859,  the  Chairman  read  the  following  extracts  from  a  paper  he 
had  received,  originating  from  a  respectable  mercantile  house  at 
Constantinople,  and  relating  to  the  manufacture  of  otto  of  roses : 
The  distilling  of  otto  of  roses  being  completed,  including 
those  places  lying  in  the  centre  of  the  Balkan  mountains,  we 
beg  to  submit  the  result  in  the  following  report : — 
In  order  the  better  to  arrive  at  the  quantity  of  otto  produced, 
we  herewith  give  a  list  of  all  the  places  from  which  it  is  procured  ; 
the  number  of  stills  noted  below  we  have  with  much  trouble  as- 
certained personally,  and  we  can  say  with  certainty  that  on  the 
whole  not  more  than  2  per  cent,  of  the  manufacturers  have  been 
left  out.
