tion  to  note  that  just  as  hyenanchin  occurs  along  with  the  non-toxic 
isomeride,  picrotoxinin  is  associated  in  cocculus  indiciis  with  the 
inactive  substance  picrotin.  All  four  substances  are  dilactones  and 
whilst  picrotoxinin  and  its  associate  yield  acetone  on  distillation 
with  alkalis,  hyenchanin  and  its  isomeride  yield  hydroxyacetone. 
The  subsidiary  components  of  Hyenanche  include  a  new  wax 
alcohol  C24H49OH,  a  new  phytosterol  C2sH460  and  a  new  yellow 
colouring  matter  C15H1206  belonging  to  the  flavone  series  and 
showing  some  characteristics  in  common  with  morin. 
THE  TRADE-MARK  ACT  OF  1920.

Help  in  holding  business  already  won  and  in  gaining  new 
patronage  is  given  manufacturers  and  exporters  by  the  trade-mark 
law  of  1920. 
Before  the  passage  of  this  law,  there  were  trade-marks  in  use 
which  could  not  be  registered  under  the  Trade-Mark  Act  of  Feb- 
ruary 20,  1905. 
That  is  to  say,  although  the  validity  of  such  trade-marks  was 
acknowledged  in  common  law,  they  did  not  meet  the  requirements 
of  the  United  States  Patent  Office. 
In  many  instances,  such  trade-marks  earned  their  popularity 
at  first  in  local  circles  of  trade.  They  served  to  identify  a  product 
in  the  community  where  it  was  made  and  sold. 
When  devising  these  emblems,  manufacturers  had  in  mind  some 
symbol  which  would  not  be  hard  to  remember.  Moreover,  they 
sought  to  compose  a  token  which  would  be  different  enough  from 
other  trade-marks  to  enable  people  easily  to  recognize  the  goods 
to  which  it  was  applied. 
Not  much  thought  was  spent  upon  whether  or  not  the  trade- 
mark could  obtain  registration  in  the  Patent  Office  at  Washington, 
D.  C. 
There  were  numer  ous  cases  in  which  a  time  came  when  the
