GLEANINGS  FROM  GERMAN  JOURNALS. 
is  colored  deep  violet  by  a  drop  of  solution  of  sesquichloride  of 
iron. — Zeitschr.  des  oesterr.  Apoth.  Ver.  1869,  11. 
Eucalyptus  globulus^  Lahill.  has,  according  to  Schiitzenberger, 
been  introduced  from  Australia  into  Spain,  near  Santiago,  which 
has  a  very  moist  climate,  and  in  July  and  August  is  usually  vis- 
ited by  cold  northern  winds.  The  leaves  are  extolled  as  a  feb- 
rifuge and  anodyne. — Ibid.^  17. 
Resina  Wangelim  pedra  is  a  resin  found  in  the  cavities  of  old 
Brazilian  trees,  the  Ferreira  spectabilis,  Fr.,  Allem.  Leguminosae, 
viii,  Dalbergiese.  Dr.  Peckolt  stated  that  it  consists  almost 
wholly  of  a  volatile  alkaloid,  which  he  named  angelina,  and  which 
yields  with  acids  crystallizable  salts.  Dr.  W.  F.  Gintl,  of 
Prague,  finds  (Sitzungsber.  d.  kais.  Akad.  d.  Wissensch.)  that 
this  substance  is  almost  insoluble  in  cold  water,  in  alcohol 
and  ether,  has  a  neutral  reaction,  dissolves  readily  in  acids 
without  neutralizing  them,  and  crystallizes  from  these  solutions 
in  combination  with  the  acids ;  the  compounds,  however,  are 
completely  decomposed  by  much  water.  Diffused  in  water  and 
boiled  with  little  nitric  acid,  a  rose  red  color  is  produced,  chang- 
ing to  ruby,  and  finally  through  violet  into  blue ;  more  nitric 
acid  produces  a  green  and  finally  a  brown  color.  These  colored 
solutions,  except  the  last,  show  a  beautiful  red  fluorescence. 
The  liquid  obtained  by  treating  angelina  with  concentrated  sul- 
phuric acid,  and  then  neutralizing  with  carbonate  of  baryta,  is 
colored  violet  by  ferric  chloride.  It  fuses  and  volatilizes.  The 
sublimate,  however,  has  different  properties.  Its  composition  is 
NOg.  All  these  reactions  prove  the  substance  to  be 
identical  with  the  so-called  rhatanin  of  Dr.  Emil  Ruge,  which  he 
found  in  the  South  American  extract  of  rhatany,  and  which  can 
not  be  obtained  from  rhatany  root.  Dr.  G.  suggests  that  some 
varieties  of  kino  obtained  from  the  order  Dalbergiese  are  used  as 
substitutes  or  adulterations  of  extract  of  rhatany,  which  may 
account  for  its  containing  the  so-called  rhatanin,  unless  some 
portion  of  Krameria  triandra  should  contain  it. — Ibid.,  p.  32 — 37. 
Sgrupus  Diacodii,  prepared  according  to  the  Austrian  Phar- 
macopoeia, by  digesting  poppy  heads  for  two  hours  with  hot 
water,  contains,  according  to  Alfred  Siersch,  less  than  half  the
