ciliolate.  Petals  coriaceous,  lanceolate,  acute,  furnished  with  prominent  midrib,  in- 
flexed  at  the  upper  margin  and  at  the  apiculus.  Stamens  shorter  than  the  petals. 
Onjary  depressed,  globose,  very  smooth,  half  included  in  the  disk,  and  crowned  with 
a  short,  rather  thick  style." 
The  figure  represents  the  leaves  being  slightly  emarginate.  In  the 
greyish-green  leaves,  slender  peduncle  and  pedicels,  and  smooth  fruit, 
P.  Selloanus  agrees  with  the  Jaborandi  plant  ;  but  the  pedicels  of  P. 
Selloanus  are  longer  and  hairy  \  this,  however,  future  specimens  of 
Jaborandi  may  perhaps  prove  to  be  of  no  importance. 
P.  pennatifolius^  L^m.,is  described  as  having  hright  green  leaves,  hairy 
on  the  veins  beneath,  and  a  thick  peduncle  with  short  thick  pedicels. 
So  far,  therefore,  as  the  most  recent  researches  on  this  genus  have 
made  known  the  species,  Jaborandi  must  be  said  to  approximate  more 
nearly  to  P.  Selloanus  than  to  P.  pennatifolius^  Lem. — Pharm,  your,  and

MINUTES  OF  THE  PHARMACEUTICAL  MEETING. 
The  sixth  meeting  of  the  session  was  held  March  i6th,  1875,  Dr.  Pile  being  in 
the  chair,  welcomed  the  many  strangers  present. 
The  following  donations  were  made  to  the  cabinet: 
By  Mr.  Betanelly,  a  handsome  specimen  of  the  flowers  of  Pyrethrum  roseum,  imported 
this  season  5  by  Dr.  Miller,  glucose,  made  from  wheat,  very  white,  with  sweet  taste, 
without  any  nauseous  bitterness  whatever,-  it  had  been  used  by  R.  V.  Mattison  as  an 
excipient  in  pill  masses,  and  by  A.  P.  Brown  in  the  preparation  of  syrup  of  the  lacto- 
phosphates.  He  presented  also  cosmolin  ointment,  which  closely  resembles  cosmolin, 
and  is  prepared  from  one  part  of  paraffin  and  sixteen  parts  lubricating  oil — the  oil  Is 
repeatedly  filtered  through  animal  charcoal  and  by  aid  of  a  water-bath  formed  into 
an  ointment  with  the  paraffin,  Joseph  L.  Lemberger  remarked  that  it  was  a  near 
aproach  to  cosmolin,  and  if  it  will  answer,  we  need  nothing  better.  Dr.  Miller  also 
presented  pure  oil  of  origanum,  the  price  of  which  is  far  in  excess  of  the  quotations 
for  the  commercial  article,  and  oil  of  red  thyme,  which  is  sold  for  origanum,  the  so- 
called  oil  of  white  thyme  being  produced  by  redistillation  of  the  red. 
Prof.  Maisch  exhibited  the  following  specimens  of  American  volatile  oils  made  by 
George  G.  Percival  of  Waterville,  Maine,  Abies  Canadensis,  Abies  nigra,  Tanacetum, 
Hedeoma  and  Solidgo.  Mr.  Percival  has  a  patent  for  their  preparation  by  means  of 
hot  water,  they  being  more  soluble  in  hot  than  in  cold  water,  but  he  states  that  ab- 
solutely pure  oils  cannot  be  manufactured  for  the  prices  at  which  the  usual  commercial 
qualities  are  offered.  Dr.  Pile  and  Prof.  Maisch  bore  testimony  to  this  fact  from 
personal  experience  in  the  production  of  a  few  volatile  oils  5  under  the  most  favorable 
circumstances  the  cost  was  from  three  to  sixteen  times  the  market  quotations. 
C.  L.  Eberle  thought  that  other  products,  such  as  some  chemicals,  were  subject  to 
the  same  drawback,  more  especially  if  the  cost  of  the  pharmacist's  labor  be  added,
