Wine  of  Coca. — Bruised  coca  leaves  30  grms.,  60  per  cent,  alco- 
cohol  60  grms.,  macerate  for  24  hours  ;  then  add  wine  (vin  de  Lunel) 
1,000  grms.,  macerate  for  10  days  with  frequent  agitation,  and  filter.

Extract  of  coca  is  made  by  displacement  with  60  per  cent,  alco-

Syrup  of  Coca. — Coca  leaves  100  grms.,  boiling  water  1,000  grms., 
infuse  for  24  hours,  express,  filter  and  dissolve  175  grms.  sugar  in

Iodinized  Cotton. — 2  grms.  of  finely-powdered  iodine  is  sprinkled 
over  25  grms.  of  cotton  as  uniformly  as  possible,  which  is  then  intro- 
duced into  a  wide- mouthed  glass  stoppered  bottle  that  had  been  kept 
for  a  few  minutes  in  nearly  boiling  water  to  expel  some  air.-  The 
stopper  is  then  securely  fastened  and  the  bottle  heated  for  at  least  two 
hours  to  a  temperature  of  ioo°C,  until  the  cotton  has  become  uni- 
formly impregnated  with  the  iodine.  The  bottle  must  be  allowed  to 
cool  before  it  is  opened,  and  the  cotton,  which  contains  8  per  cent,  of 
iodine,  must  be  kept  in  glass- stoppered  vials  (see  also  "Amer.  Journ. 
Pharm.,"  1876,  p.  131). 
Diastase. — Malt,  of  which  the  germ  has  attained  two-thirds  the 
length  of  the  barley  grain,  and  dried  at  50°C,  is  ground,  macerated  at 
the  ordinary  temperature  for  5  or  6  hours  with  twice  its  weight  of 
water,  then  expressed,  filtered  and  the  liquid  mixed  with  twice  its 
bulk  of  95  per  cent,  of  alcohol.  The  precipitate  is  collected,  spread 
in  thin  layers  upon  plates  of  glass,  and  rapidly  dried  in  a  current  of  air 
at  a  temperature  of  45°C. 
8*5  grm.  of  diastase  added  to  200  grm.  of  paste  containing  10  grm. 
of  starch  yield  a  liquid  which  filters  very  readily  and  decolorizes  five 
limes  its  volume  of  Fehling's  solution.
