cheap  substitute  for  true  ginseng  and  prescribed  in  cases  of  sperma-

A  CONTRIBUTION  ON  SCOPOLA  CARNIOLICA. 
By  J.  B.  Nagelvoort. 
It  seems  to  me  that  there  is  no  necessity  for  the  reasoning  of  the 
Pharm.  Centralhalle  in  its  No.  7,  1890,  p.  88,  on  this  subject.  In 
case  the  rhizoma  Scopolce  carniolicez  contains  a  valuable  amount 
of  liyoscy amine  and  not  in  very  variable  quantities,  the  drug  will  be 
used,  if  not  in  medicine,  then  in  chemical  factories. 
Prof.  Fliickiger  wrote  in  his  Pharm.  Chemie,  1888,  about  Scopola 
japonica  and  sanctioned  with  his  authority  the  presence  of  mydriatic 
alkaloid  in  the  plant.  No  English  or  American  journal  had  any- 
thing to  do  with  it. 
I  refer  to  the  February  number  of  this  Journal  and  to  the  Arch, 
d.  Pharm.,  3,  1890,  for  the  leading  points.  Desire  only  to  offer  for 
record  a  corroborative  experience. 
A  quantity  of  scopola  rhizome,  derived  from  Germany  through 
the  common  channels  of  commerce,  yielded  05  per  cent,  liyos- 
cy amine.

TURPENTINE. 
By  R.  Gaillard  Dunwody,  Ph.G. 
Contribution  from  the  Chemical  Laboratory  of  the  Philadelphia  College  of  Pharmacy. — 
No.  74. 
Turpentine  is  an  oleoresin  of  a  white  semi-solid  consistency  which 
exudes  from  Pinus  palustris  and  other  species  of  the  pine  family 
when  incisions  are  made.  The  trees  are  indigenous  to  the  Southern 
States  from  Virginia  to  the  Gulf  of  Mexico.  Their  usual  height  is 
from  seventy-five  to  eighty  feet,  two-thirds  of  which  are  from 
eighteen  to  twenty  inches  in  diameter  and  destitute  of  branches ; 
the  other  third  is  branched  having  leaves  of  a  dark  green  color 
about  ten  to  fifteen  inches  in  length  situated  at  the  ends  in  clusters 
of  three,  surrounded  by  long  ragged  sheaths.  The  bark  is  dark 
brown  and  has  a  revolute  and  longitudinally-fissured  cork.  Pines 
growing  near  swampy  localities  produce  more  oleoresin,  and  have
