Glycerin  Suppositories. — Ten  parts  dry,  dialyzed  stearin  soap  are 
dissolved  in  boiling  water,  mixed  with  90  parts  pure  glycerin,  filtered 
by  means  of  a  hot-water  funnel,  the  filtrate  evaporated  to  100  parts 
and  poured  into  moulds.  Two  sizes  are  made,  weighing  respec- 
tively 1*7  and  2*5  gm.,  corresponding  possibly  to  our  15  and  30  gm. 
suppositories.  They  are  wrapped  in  tin -foil,  to  prevent  absorption 
of  moisture. — E.  Dieterich,  Pharm.  Centralh.,  1888,  445. 
Oleum  cinereum  benzoatum;  improved  formula. — 20  parts  mercury 
are  triturated  with  5  parts  of  an  ethereal  benzoin  solution  (ether  40, 
benzoin  20,  oil  of  sweet  almond  5 ;  after  solution,  filter)  until  the 
ether  has  evaporated,  when  40  parts  fluid  paraffin  are  added  and  the 
trituration  continued. — Dr.  Harting,  Pharm.  Post,  1888,  600. 
Test  for  free  sulphuric  acid. — Egger  proposes  the  furfurol  color 
reaction  (see  Amer.  Jour.  Phar.,  1888,  p.  506)  as  a  test  for  free 
sulphuric  acid,  and  his  experiments  show  that  1  cc.  of  ruho  normal 
sulphuric  acid  (containing  0*000049  gm.)  warmed  on  a  water-bath 
with  a  small  particle  of  cholic  acid  and  two  drops  of  a  furfurol  solu- 
tion, will  give  a  decided  red  coloration. — Chemiker  Ztg.,  1888,  1245. 
Permanent  starch  "paste  for  volumetric  analysis,  also  for  technical  pur- 
poses, is  made  by  mixing  50  parts  potato  starch  and  O'l  partbiniodide 
of  mercury  with  a  little  water  and  adding  this  mixture  free  from  lumps 
to  10*000  parts  boiling  water  (for  technical  use  less  water  is  taken  and 
the  paste  boiled) ;  after  standing  the  liquid  is  decanted.  This  solu- 
tion will  not  lose  its  sensitiveness  if  kept  for  a  year. — Gastine  {Bull. 
Soc.  Chim.)  Rdsch.,  1888,  783. 
Creolin  according  to  B.  Fischer  contains  hydrocarbons  66,  phenols 
27'4,  organic  bases  2*2,  ash  4*4,  composed  of  Na2S04,  NaCl  and  ]Sra2 
CO3.  It  is  made  by  freeing  that  portion  of  coal-tar  boiling  between 
180  and  220°  from  carbolic  acid.  Its  property  of  emulsifying  with 
water  is  probably  due  to  the  presence  of  small  quantities  of  phenol 
sulphonates  and  pyridine  sulphonates. — R.  Otto,  Phar.  Cntrlhalle, 
1888,  467. 
Creolin-iodoform,  sl  mixture  of  iodoform  with  one  or  two  per  cent, 
creolin,  is  considered  by  Dr.  Jaksch  to  be  the  best  antiseptic  and  deo- 
dorized preparation  of  iodoform  yet  offered.  It  is  of  a  faint  aromatic 
odor,  soluble  in  alcohol  and  ether ;  water  removes  the  creolin,  leaving 
the  iodoform.— PWm.  Post.,  1888,  630. 
Liquor  antisepticus. — Menthol  0*2,  thymol  0*5,  boric  acid  2*0, 
sodium  salicylate  1*0,  sodium  benzoate  1*0,  oil  of  gaultheria  gtt.  vi,
