it  may  earn  more  from  the  many  importers,  who  may  avail  of  its  facili- 
ties, than  it  would  if  located  at  Washington,  but  in  any  event  I  fear  it 
cannot  be  successfully  carried  out  by  the  A. Ph. A.  The  erection  of  the 
Hoffmann  Haus  in  Berlin  required  great  and  long-continued  efforts 
on  the  part  of  the  chemists  and  chemical  industries  of  the  world, 
and  we  cannot  hope  to  enlist  the  interest  of  nearly  so  many  people, 
nor  nearly  so  many  large  and  wealthy  industries.  While  hence  I 
would  prefer  to  see  a  research  laboratory  be  the  memorial  for 
Professor  Procter,  I  think  the  most  that  the  A.Ph.A.  can  hope  to 
successfully  carry  out  is  a  gold  memorial  medal  to  be  awarded 
annually  to  the  pharmaceutical  chemist  or  botanist  that  has  in  the 
judgment  of  a  suitable  committee  advanced  the  science  the  most 
during  the  year.

THE  DISTILLATION  PRODUCTS  OF  CASTOR  OIL. 
It  has  been  often  noticed  that  toward  the  end  of  the  distillation 
of  castor  oil,  the  residue  in  the  retort  very  suddenly  and  with  de- 
velopment of  considerable  gas  is  converted  into  a  sticky  rubber-like 
mass.  H.  Thorns  and  G.  Fendler  [Arch,  Ph.,  1901,  1)  report  exam- 
ination of  the  residue,  which  they  find  consists  largely  of  the  glycer- 
ide  of  a  dibasic  fatty  acid,  triundecylenic  acid  (CnH20O2)3. 
From  this  glycerine  the  anhydride  of  the  acid  was  isolated  in  the 
form  of  a  bright  yellow,  somewhat  elastic  mass,  having  the  formula 
C33H5805  which  corresponds  to  the  composition  (CuH20O2)  3-H20). 
The  residue  on  heating  with  potassa  yielded  a  new  acid  of  the  oleic 
acid  series,  a  body  melting  at  360  and  of  formula  C16H30O2.

CONCERNING  OIL  GLANDS. 
An  important  contribution  to  the  study  of  plant  processes  is  an 
article  with  above  title  by  A.  Tschirch  and  O.  Tunman  (Arch.  Ph., 
1901,  7.) 
The  special  subject  investigated  was  the  method  of  secretion  of 
resins,  or  of  oils,  or  of  gums  in  the  various  glands  or  secretion  cells, 
the  work  being  performed  by  aid  of  microscope  and  appropriate 
stains.    Among  the  latter  the  Unverdorben-Franchimont  reagent,
