with  sulphuric  acid,  and  neither  reduces  Fehling's  solution  nor  forms

FABIANA  1MBRICATA. 
To  the  knowledge  of  Pichi  Dr.  H.  Kunz-Krause  {Arch,  der  Pharm.t 
1899,  0  nas  made  a  valuable  contribution,  taking  up  the  subject 
where  left  by  Trimble,  Schroeder  and  Deitz  (Journal,  1889,  p.  405, 
et  seq.),  confirming  their  work  and  entering  into  minutiae. 
An  infusion  of  the  leaves  showed  a  considerable  quantity  of  mag- 
nesium phosphate,  a  tannin  which  he  calls  Fabiana-tannoid,  a  fluor- 
escent substance  proven  to  be  chrysatropic  acid  (oxy-methyl  cuma- 
rol,  /5  methyl  aesculetin),  while  no  alkaloids  are  present,  the  sole 
basic  principle  being  choline.  The  leaves  also  contain  a  soft  resin, 
which  yields,  on  heating  to  ico°  C.  with  diluted  acid,  a  volatile  oil, 
Fabiana  tannoid,  chrysatropic  acid  and  an  inactive  sugar. 
The  ethereal  extract  from  the  infused  leaves  contained  chloro- 
phyl,  chrysatropic  acid,  the  volatile  oil  "  Fabianol"  (which ana- 
lyzed to  C50H90O4,  boiled  at  275  0  C,  and  had  refractive  value  1-5076) 
and  Fabiana-resin,  which  appeared  in  microscopical  crystals,  melting 
at  2800  C.    The  wood  yielded  chrysatropic  acid    and  choline. 
These  preliminary  observations  were  followed  by  a  careful  study 
of  the  several  characteristic  bodies. 
The  resin  yielded  two  bromine  derivatives,  one  colorless,  of  for- 
mula C18H28Br202,  and  one  that  was  yellow  and  of  variable  compo- 
sition. It  also  yields  a  mono-acetyl  and  a  mono-benzoyl  derivative 
and  gives  negative  results  to  the  methoxyl  group  test.  Hydriodic 
acid  and  red  phosphorus  reduces  it  to  a  wax-like  substance  having 
the  formula  C54H9802.  This  fact,  together  with  the  similarity  of  the 
resin  to  Fabianol,  C54H90O2,  brings  the  author  to  the  conclusion  that 
the  combustion  formula  of  the  resin,  C18H30O2,  should  be  trebled. 
Lastly,  the  resin,  when  melted  with  soda  and  potassa,  oxidizes  to  a 
body  behaving  like  vinyl-para  methoxyl-pyro-catechin,  a  point  of 
value  in  the  study  of  resins. 
•The  tannin  proved  a  glycotannoid,  behaving  like  caffetannic 
acid,  which  the  author  previously  showed  to  be  glycosyl  dioxy  cin- 
namic  acid.    It  yields  a  bromin  product,  whose  halogen  percentage
