in  colorless  cross-like  crystals  fluorescent  at  the  edges  and  deliques- 
cent. The  hydrochlorate  crystallizes  best  in  octahedral  form,  and 
can  be  obtained  in  quantity  from  0*3  to  0*5  per  cent.  The  nitrate 
does  not  crystallize  even  when  attempted  over  H2S04,  resembling  ni- 
trate of  emetine.  PtCl4HgI22KI,  Nessler's  reagent,  and  iodine  solu- 
tion yield  precipitates ;  Na  OH  on  boiling,  evolves  the  odor  of  trimethy- 
lamine.  The  yield  of  emetine  by  the  ferric  chloride  and  potassium 
carbonate  method  of  estimation  is  greater  •  than  by  other  methods, 
hence  this  precludes  the  decomposition  of  emetine. — Apoth  Ztg.,  1888,

Oxygen  can  be  prepared  handily  by  the  action  of  hydrogen  dioxide 
upon  potassium  permanganate ;  100  cc.  of  the  commercial  hydrogen 
dioxide,  3  per  cent,  will  yield  about  one  liter  oxygen.  A  generating 
flask  is  half  filled  with  the  H202,  made  alkaline  by  a  few  drops  of 
NH4OH,  and  K2Mn208,  is  slowly  added  through  the  funnel-tube  (5cc. 
of  a  0.3  per  cent,  solution),  when  the  reaction  ceases  more  of  the 
K2Mn208  is  added.  All  of  the  available  oxygen  has  been  obtained  if 
the  liquid  in  the  flask  retains  a  red  color  on  acidifying  with  sulphuric 
acid.—  C.  F.  Gbhring,  Chem.  Ztg.,  1888. 
W.  Lindner  recommends  the  use  of  an  acid  solution  of  H202. —

Inalterable  Iodide  of  Potassium  Ointment. — A  writer  in 
the  Gior.  Farm.  Trent,  gives  the  following  :  Iodide  of  potassium,  white 
Venice  soap,  distilled  water,  of  each,  100 ;  glycerin,  600 ;  fresh,  or 
benzoinated  lard,  300.  Dissolve  the  iodine  in  the  water  (using  a  water- 
bath),  and  then  the  soap;  add  the  glycerin,  and  afterward  the  lard. 
As  soon  as  the  lard  has  melted  stir  rapidly  and  continually,  and  stand 
the  dish  in  cold  water. — Repert.  de  Phar.,  Nov.  1888. 
Incompatibility  of  Chlorate  of  Potassium  and  Iodide  of 
Iron. — Sesquioxide  of  iron  is  formed,  and  the  iodine  set  free:  2  Fe 
I2  +  KCIO3  ==  Fe2  O3  +  KC1  +  4  1.  The  administration  of  this 
mixture  caused  death. — Boll.  Farm.;  U  Union  Phar.,  Dec.  1888. 
Glycerin  Suppositories. — The  following  formulae,  presented  by 
Nouv.  Rem.,  Dec.  24,  are  brought  together  from  German  sources;  1.
