of  human  beings.  The  following  is  an  example  of  the  method  of 
labeling  these  preparations:  "tincture  cinchona  meth." 
He  then  spoke  of  the  importance  of  the  interstate  commerce 
regulations,  and  said  that  a  manufacturer  in  Pennsylvania  who 
uses  wood  alcohol  in  the  manufacture  of  preparations  to  be  sold 
in  his  own  State  does  not  use  it  in  the  products  sent  to  other 
States.  Attention  was  also  directed  to  the  fact  that  sweepings  are 
imported  into  this  country  and  admixed  with  the  genuine  drugs,  or 
they  are  sometimes  powdered  and  sent  out  to  the  trade. 
Prof.  John  Uri  Lloyd  said  that  the  valley  of  the  Menander  River 
furnishes  the  licorice  used  in  the  manufacture  of  tobacco.  He  said 
that  wherever  there  is  a  wheat  field  or  vineyard,  there  the  licorice 
plant  is  found.  It  is  so  abundant  as  to  be  regarded  as  a  weed  and 
cannot  be  eradicated,  The  extract  of  licorice  made  in  that  region 
supplies  the  European  market,  but  none  of  it  is  sent  to  this  country 
on  account  of  the  import  duty.  He  said  that  the  method  of  manu- 
facture of  the  extract  is  rather  primitive,  but  that  the  product  is  pure, 
as  there  is  nothing  cheaper  than  licorice  itself.

Chemical  Examination  of  Grindelia.    Part  II. 
By  Frederick  B.  Power  and  Frank  Tutin. 
(Read  by  Virgil  Coblentz.) 
This  is  a  continuation  of  the  work  reported  by  the  authors  at  the 
meeting  of  the  association  in  1905.  The  drug  used  was  probably 
Grindelia  camporum,  Greene.  In  the  previous  paper  the  authors 
reported  the  isolation  of  the  hydrocarbon  hentriacontane,  C31H64,  a 
new  phytosterol  (m.  p.  1660  C.),  1-glucose,  tannin,  amorphous  color- 
ing matter,  formic  acid  and  an  essential  oil.  The  chief  constituents 
are  amorphous  resins,  which  have  now  been  further  examined. 
These  resins,  which  are  soluble  in  petroleum,  consist  to  a  large 
extent  of  a  complex  mixture  of  liquid  acids.  These  acids  are  for 
the  most  part  optically  active,  unsaturated  cyclic  compounds.  Some 
of  them  are  oxy-acids  and  appear  to  contain  benzene  nuclei.  A 
very  small  amount  of  cerotic  acid  and  apparently  a  trace  of  palmitic 
acid  are  also  present.  Another  hydrocarbon  has  also  been  isolated, 
which  consists  for  the  most  part  of  a  complex  mixture  of  esters, 
presumably  glycerides.
