GLEANINGS  FROM  GERMAN  JOURNALS. 
Pure  MetJiylic  Alcohol  does  not  yield  iodoform  witli  potassa 
and  iodine  ;  its  formation  points  out  impurities,  like  aceton, 
ethjlic  alcohol,  &c. — A.  Ziehen,  in  Annal.  d.  Qhem.  und  Pharm.^

Ferricyanide  of  Potassium.  Prof.  E.  Reicbardt  recommends, 
even  on  the  large  scale,  the  substitution  of  chlorine  by  bromine 
for  oxidizing  the  ferro-  to  the  ferricyanide  of  potassium.  If 
bromine  be  added  in  small  quantities  the  reaction  will  be  com- 
pleted after  some  agitation  in  a  few  minutes  ;  the  crystallizing 
salt  will  be  much  purer  than  if  made  by  chlorine,  and  from  the 
mother  liquor  the  bromine  may  be  recovered.  Archiv  d.  Ph., 
April,  1870,  48-50. 
Extract  of  3Ieat.  Prof.  Reichardt  has  analyzed  an  extract 
of  meat,  which  has  made  its  appearance  in  German  commerce 
and  is  prepared  by  Buschenthal  &  Co.,  in  Montevideo.  After 
comparing  his  results  with  Liebig's,  Vogel's  and  his  own  analysis 
of  the  extract  furnished  by  the  Liebig  Company  of  FrayBentos, 
he  comes  to  the  conclusion  that  the  absolute  purity  of  Buschen- 
thal's  preparation  cannot  be  doubted. — Ibid.  55-57. 
Bellis  perennis,  Lin.  J.  B.  Enz  has  analyzed  the  flowers  of 
this  plant  with  the  following  result:  Loss  on  drying,  8*14; 
etherial  extract,  1-8,  containing  tannin  (green  precipitate  with 
iron  salts),  volatile  oil,  malic  acid,  potassa  and  lime  salts,  wax, 
fat,  chlorophyll,  fermentable  sugar,  acrid  and  bitter  principle; 
alcoholic  extract  3-2,  containing  sugar,  tannin,  tartaric  and 
malic  acids,  potassa  and  lime  salts,  resin,  anthoxanthin,  acrid 
and  bitter  principle;  aqueous  extract  7*0,  containing  mucilage, 
anthoxanthin,  potassa,  lime  and  magnesia  in  combination  with 
tartaric,  malic,  muriatic,  sulphuric  and  phosphoric  acids  ;  1*1 
extracted  by  very  dilute  muriatic  acid,  consisting  of  pectin,  gum, 
oxalate  of  lime  and  phosphates  of  lime  and  magnesia;  3  per 
cent,  albuminous  matter  was  extracted  by  dilute  potassa  solu- 
tion ;  a  minute  quantity  of  volatile  oil  and  2*5  per  cent,  lignin. 
The  author's  process  for  obtaining  a  solution  of  the  odorous 
principle  appears  to  be  applicable  for  other  vegetable  substances  ; 
it  is  as  follows :  the  flowers  are  macerated  for  a  week  with  gly- 
cerin, expressed,  the  liquid  diluted  with  water,  agitated  with 
chloroform,  the  chloroformic  solution  evaporated  spontaneously,
