chrysarobin  and  pyrogallic  acid  cannot  well  be  made  with  a  basis  of 
lead.  He  obtains  good  preparations  with  oleate  of  alumina  for  such 
plasters  as  are  not  intended  to  irritate,  as,  for  instance,  those  of  oxide 
of  zinc,  boracic  acid,  etc.  For  salicylic  acid,  creasote,  pyrogallic 
acid,  chrysarobin,  anthrarobin,  etc.,  a  solution  of  caoutchouc  in 
benzol  is  used.  For  example  :  Lanolin,  60  gm. ;  benzinic  solution  of 
caoutchouc,  30  gm. ;  anthrarobin,  10  gm.  Pulverize  the  anthrarobin 
well  and  incorporate  it  with  the  lanolin ;  melt  with  gentle  heat,  add 
the  benzinic  solution  and  agitate  until  complete  evaporation  of  the 
benzol.    The  formula  is  suitable  for  other  plasters. 
To  Dissolve  Naphthol. — For  concentrated  solutions,  or  topical 
mixtures,  alcohol  is  used.  For  washes  or  gargles  the  above  may  be 
mixed  with  honey  fully  liquified  by  heat.  These,  if  the  honey  is  free 
from  water,  remain  limpid  for  two  or  three  days.  Diluted  solutions 
are  not  so  easily  made,  for,  apart  from  alcohol,  only  alkalies  or  alka- 
line salts  can  be  used,  and  these,  combining  with  the  naphthol, 
produce  comparatively  weak  antiseptic  solutions.  The  benzoate  of 
soda  is  useless  here.  The  alcoholic  solution  may,  for  some  purposes, 
be  diluted  with  soap  and  water ;  but  the  best  method  seems  to  be  to 
first  dissolve  the  naphthol  in  camphorated  alcohol.  Camphor  liqui- 
fies dry  naphthol,  and  it  retains  the  property  to  some  degree  in  mix- 
tures of  water  with  camphorated  alcohol.  But,  although  naphthol 
in  camphorated  alcohol  mixes  more  easily  with  water  than  does 
the  pure  alcoholic  preparation,  it  does  not  form,  strictly  speaking,  a  • 
solution. — Repert.  de  Phar.,  June  10. 
Enemata  of  Hypnone,  Chloral  and  Sulphonal. — M.  P. 
Vigier  recommends  a  formula  as  follows  :  Hypnone,  10  to  20  drops ; 
powdered  gum,  3  gm. ;  oil  of  sweet  almonds,  5  gm. ;  water,  150  gm. ; 
for  one  enema.  Mix  the  oil  and  gum  in  a  mortar,  add  the  water, 
and  introduce  the  hypnone  a  little  at  a  time  while  beating.  Emul- 
sion is  perfectly  effected  in  five  minutes.  The  hypnone  may  be 
replaced  by  1  or  2  gm.  of  chloral  or  of  sulphonal. — L'  Union  Phar.,

Ural — This  new  hypnotic  is  obtained  by  dissolving  urethan  in 
chloral.  It  appears  in  the  form  of  crystals,  soluble  in  alcohol,  spar- 
ingly* so  in  water  and  fusing  at  106°  C.  [222'8°  F.]  It  has  a  bitter 
taste  and  volatilizes  without  decomposing.  According  to  Puppi,  ural 
is  the  most  rapid  and  certain  of  all  known  hypnotics.  It  gives  rise 
to  no  modification  of  blood  pressure.    No  accidents  have  resulted
