GLEANINGS  IN  MATERIA  MEDICA. 
By  the  Editor. 
Venezuela  Sandalwood,  Tree. — Win.  Kirby  gives  a  minute  descrip- 
tion of  the  anatomy  of  the  leaf  and  leaflets  of  this  tree  {Phar.  Jour, 
and  Trans.,  June  15,  1886),  which  does  not  differ  to  any  great  extent 
from  that  of  most  bifacial  leaves.  The  leaf  has  two  rows  of  palisade 
cells,  and  7  or  8  rows  of  rather  close  parenchyma  cells ;  the  lower 
epidermis  is  papillose.  The  chief  characteristic  is,  however,  the 
numerous  oil  receptacles  distributed  over  the  lamina,  and  located 
usually  below  the  uppermost  row  of  palisade  cells,  but  also  found  at 
the  lower  surface,  especially  near  the  mid  rib,  and  small  ones  occa- 
sionally in  the  mid  rib  itself  near  its  dorsal  surface  ;  these  oil  cavities 
are  without  epithelium.  From  the  microscopical  structure  of  the 
leaves  and  of  the  stem  (see  June  number,  p.  296),  the  author  con- 
cludes that  the  tree  belongs  to  the  Rutacese. 
Chelidonium  majus,  Linne. — Ernst  Schmidt  has  shown  (Archiv  d. 
Phar.,  June,  1886,  p.  531),  that  Zwenger's  chelidoninic  acid  is  identical 
with  succinic  acid,  as  was  stated  by  Walz  in  1860;  also  (ibid.,  p.  513) 
that  chelidonic  acid  is  identical  with  Weppen's  veratric  acid. 
Bowdichia  major,  Martius. — Peckolt  isolated  from  the  bark  of  this 
Brazilian  tree  (see  Am.  Jour.  Phar.,  1876,  p.  510)  the  crystallizable 
glucoside  sieopirin  which  was  not  examined  physiologically.  A. 
Petit  claims  to  have  isolated  from  the  bark  an  alkaloid,  which  in 
guinea  pigs  caused  convulsions  and  had  narcotic  and  mydriatic 
properties. 
The  nearly  allied  alcornoco  bark,  from  B.  virgiloides,  Kunth,  contains 
a  neutral  crystalline  principle,  which  was  observed  by  Biltz,  Frenzel, 
(1843)  and  Spirgatis  (1871),  and  which  seems  to  be  of  a  waxy  nature. 
An  alkaloid  was  also  not  found  by  Geiger. 
Guilandina  JBonduc,  Linne.— From  the  cotyledons  of  the  yellow 
seeds  of  this  tree,  Heckel  and  Schlagdenhauffen  (Comptes  rend,  ciii, 
p.  89)  have  isolated  the  bitter  principle  in  the  form  of  a  white  powder
