should  be  preferred  before  those  which  are  imported,  especially 
in  times  like  the  present,  when  the  whole  nation  should  hus- 
band every  resource,  however  trifling,  for  martial  purposes. 
Some  recommend  that  the  remedy  be  given  in  large  quanti- 
ties, and  during  a  number  of  days,  and  without  the  adjuvant  of 
a  cathartic,  for  the  emulsion  itself  when  thus  administered  acts 
as  a  laxative ;  but  we  think  an  active  cathartic  should  never 
be  omitted,  for  its  operation  is  capable  of  expelling  a  worm  en- 
feebled by  the  effects  of  the  medicine,  but  not  to  a  degree  to 
insure  its  death  if  left  in  the  alimentary  canal.  It  may  be 
proper  to  say,  that  among  the  people  who  have  experience  with 
domestic  remedies,  there  is  an  opinion  somewhat  prevalent,  that 
the  pumpkin  seed  is  an  efficient  remedy  for  the  destruction  of 
the  ascarides  lumbricoide3,  but  I  am  not  aware  that  this  has 
been  confirmed  by  the  observation  of  the  profession. —  Chicago

ON  THE  ROOT-BARK  OF  THE  CINCHONJE. 
By  J.  E.  Howard,  F.L.S. 
A  letter  from  a  gentleman  owning  a  district  in  New  Grenada, 
containing  trees  of  Cinchona,  has  been  put  into  my  hands  by 
Mr.  Markham.  It  shows  very  satisfactorily  that  the  reproba- 
tion of  the  practice  of  extirpating  these  trees,  which  has  found 
utterance  in  England,  is  beginning  to  produce  a  salutary  effect 
in  South  America. 
The  letter  is  from  Don  Narciso  Lorenzano,  and  is  dated 
Bogota,  March  4th,  1864.  He  writes  to  his  correspondent 
( —  Griffiths,  Esq.)  as  follows  : — 
« I  have  to  thank  you  for  having  sent  me  a  copy  of  the 
«  Edinburgh  Review '  of  last  year,  in  which  I  have  had  the 
satisfaction  of  reading  the  article  on  the  cultivation  of  the 
quina  trees  in  the  East  Indies.  Permit  me  to  congratulate 
you  on  the  successful  result  of  this  undertaking,  which  partly 
ensures  the  supply  of  so  precious  a  drug  for  the  future.  It 
appears  to  me  that  the  principal  motive  which  induced  the 
government  of  India  to  commence  this  cultivation,  after  over- 
coming so  many  difficulties,  was  the  fear  that  the  quina  trees 
would  be  extirpated,  in  consequence  of  the  disorder  and  waste
