Hesse  from  opium,  it  also  resembles  macleyine  found  by  Eyckman  in 
Macleya  cordata,  and  the  alkaloid  present  in  Stylophoron  root.  The 
alkaloids  can  be  obtained  in  the  following  manner  :  The  powdered 
material  is  extracted  with  alcohol  containing  acetic  acid,  water  is 
added  and  the  alcohol  distilled  off,  the  aqueous  solution  is  filtered, 
made  alkaline  with  ammonia  and  extracted  with  chloroform,  the  lat- 
ter is  distilled  off  and  the  residue  treated  with  alcohol  containing 
HC1,  in  which  the  hydrochlorates  of  protopine  and  chelidonine  are 
insoluble.  The  alcoholic  solution,  after  addition  of  water,  is  distilled, 
the  aqueous  solution  diluted  with  water  containing  HC1  filtered  and 
ammonia  added  in  excess  ;  /9-homochelidonine  remains  in  solution 
and  is  obtained  by  extraction  with  chloroform,  the  precipitated 
chelerythrine  and  a-homochelidonine .  is  treated  with  ether  which 
removes  the  chelerythrine. — Dr.  F.  Selle,  Arch,  der  Pharm.y  1890,

Veratrum  Album. — An  alkaloidal  examination  of  this  rhizome 
by  George  Salzberger  revealed  the  presence  of  the  following  alka- 
loids having  the  formulas : — Protoveratrine  C32H51NOn,  Protovera- 
tridine  C26H45N08,  Pseudojervine  C29H43N07,  Jervine  C26H37N03  and

Daturic  Acid,  a  new  fat  acid,  has  been  prepared  by  M.  Gerard, 
{Comptes  rendus,  Acad,  des  Sci,  Aug.  11)  from  the  seeds  of  Datura 
Stramonium,  which  yield  25  per  cent,  of  oil  when  extracted  by 
ether.  Purified  with  petroleum,  this  oil  was  of  a  greenish- 
yellow  color.  It  was  saponified  with  litharge  ;  then  the  lead  oleates 
were  removed  by  ether,  leaving  a  soap,  from  which  the  author 
isolated  an  acid  fusing  at  55°  C.  M.  Gerard  places  daturic  acid 
between  palmitic  and  stearic  acids,  and  it  presents  analogous  prop- 
erties to  these.  It  crystallizes  by  cold  from  85  per  cent,  alcohol, 
giving  groups  of  fine  needles.  It  is  fairly  soluble  in  cold  alcohol, 
and  very  soluble  in  ether  and  benzin.  It  has  the  formula  C34H3404 
(old  notation). — R'epert.  de  Phar.t  Sept.  10. 
Antiseptol,  or  Iodo-Sulphate  of  Cinchonine. — M.  Yvon  (Nouv. 
Rem.)  makes  this  preparation,  for  therapeutic  use,  as  follows:  The 
sulphate  of  cinchonine  is  dissolved  in  water,  using  25  gm.  of  the 
salt  to  2,000  gm.  of  water,  and  the  precipitate  formed  by  the  use  of
