is  unduly  dilute,  the  volume  of  "crude  ether  "  separated  is  increased  0*5  per 
cent,  for  each  12*5  per  cent,  of  water  present  in  excess. 
3.  The  method  of  the  "British  Pharmacopoeia"  can  be  applied  to  the 
product  of  the  U.  S.  P.,  and  will  secure  uniform  results.  To  this  end  the 
distillate  is  brought  to  measure  not  over  one- half  the  expected  quantity  of 
spirit  (32  fluidounces  is  a  convenient  quantity) ;  this  is  tested  according  to  the 
directions  of  "British  Pharmacopoeia and  is  then  further  diluted  with  19 
volumes  of  stronger  alcohol  for  each  1  volume  indicated  in  excess  of  five  per 
cent. 
At  a  future  distillation  it  will  be  my  aim  to  repeat  some  of  the  fore- 
going experiments,  and  especially  to  determine  whether  rapid  heating 
to  170°  F.  will  insure  the  full  quantity  of  distillate  required  by  the 
"  Pharmacopoeia  "  without  inconveniently  prolonged  heating.

Elixir  of  Monobromated  Camphor.— J.  Munday  has  modified  his 
previous  formula  (see  p.  176),  because  the  glycerin  has  not  sufficient 
sweetening  properties  to  overcome  the  nauseous  taste.  He  now  pro- 
poses to  mix  spirit  of  cinnamon  (1  in  50)  ^xv,  red  elixir  (Amer.  Phar. 
Assoc.)  3xx  and  syrup  q.  s.,  to  make  §v,  and  dissolve,  by  the  aid  of  a 
water-bath,  monobromated  camphor  9i.  Each  half-ounce  contains  2 
grains. 
Elixir  Camphorae  Monobromatae  Comp.,  which  is  often  prescribed 
in  Paris,  is  made  by  dissolving  butylchloral  gr.  iii  in  spir.  cinnamon 
giss,  mixing  the  solution  with  tinct.  gelsemium  n^x,  red  elixir  giss  and 
sufficient  svrup  to  make  §ss,  and  dissolving  therein  2  grains  of  mono- 
bromated camphor. — Phar.  Jour,  and  Trans.,  April  7. 
Chrysophanic  acid  ointment  has  been  recommended  by  Mr.  Balm. 
Squire,  in  place  of  Goa  powder,  in  the  treatment  of  ringworm,  psori- 
asis and  other  skin  diseases.  To  prepare  it,  he  recommends  to  dissolve 
2  drachms  of  the  acid  and  1  oz.  of  lard  in  the  smallest  necessary  quan- 
tity of  benzol,  using  a  small  beaker,  placed  in  a  water-bath,  and  when 
the  solution  has  been  effected,  to  promptly  transfer  it  to  an  evaporating 
dish  placed  in  cold  water,  stirring  briskly  until  the  solution  has  become 
fully  and  firmly  "  set "  ;  the  benzol  evaporates  readily,  and  a  uniform
