Delta. — The  supernatant  liquid  of  the  precipitate  (b)  was  made 
acid  with  hydrochloric  acid,  which  precipitated  a  reddish  brown 
substance  in  flocks,  which  after  solution  in  alcohol  and  evaporation 
formed  into  a  soft  mass. 
The  different  physical  characters,  together  with  the  following 
reactions  with  reagents,  have  led  me  to  believe  the  four  above- 
named  substances  to  be  different.

The  original  resin  is  bronze  colored,  but  if  left  in  contact  with 
air  becomes  dark  green. 
In  the  analysis  of  the  drug  the  scheme  of  Dragendorff  was 
followed. 
I.  The  drug  was  ground  in  an  iron  mortar  until  all  passed 
through  a  No.  80  sieve.  After  the  iron,  which  had  been  mechani- 
cally obtained  from  the  mortar,  was  removed  by  a  magnet,  one 
gram  was  heated  in  an  air  bath  at  no°  C.  to  constant  weight, 
which  was  -9124  Gm.,  making  a  loss  of  -0876  Gm.,  of  which  -0665 
Gm.  was  volatile  oil,  the  remainder,  -02 11  Gm.,  being  moisture. 
II.  One  gram  was  ignited  at  a  low  red  heat  in  a  platinum 
crucible.  The  resulting  ash  weighed  -1269  Gm.,  of  which  -0171  Gm. 
was  soluble  in  water,  -0605  Gm.  soluble  in  hydrochloric  acid  '0493 
Gm.  insoluble  in  these  solvents.  The  ash  consisted  of  the  usual 
constituents. 
III.  Ten  grams  of  the  drug  were  macerated  for  eight  days  in 
100  cc.  of  petroleum  spirit,  boiling  between  400  and  8o°  C.  with 
occasional  shaking.
