92  Revision  of  the  U.  S.  Pharmacopoeia.  {Am,SiSarm' 
should  be  made  (similar  to  the  Committee  of  the  U.  S.  P.)  We 
are  aware  of  many  objections  that  may  be  raised,  but  these  in  time, 
after  reflection,  might,  too,  vanish  like  the  stagnant  pools  and 
marshes  in  the  suburbs  of  Chicago  upon  which  the  White  City  was 
built. 
By  v/ay  of  further  suggestion  let  us  see  what  a  World's  Botanical 
Exposition  might  contain.  One  building  might  be  devoted  to  the 
interests  of  morphological  and  systematic  botany.  Here  could  be 
displayed  the  models,  charts  and  methods  illustrating  the  study  of 
morphology.  Also  the  different  methods  of  collecting,  drying,  pre- 
serving and  classifying  plants.  Laboratories  might  be  equipped  and 
work  shown  with  information  thereupon  given.  A  similar  exhibit 
might  be  made  in  the  building  devoted  to  anatomical  and  physio- 
logical botany.  In  the  building  devoted  to  medical  botany,  an 
exhibition  (as  interesting  as  that  in  the  Manufactures  and  Liberal 
Arts  Building  might  be^made),  consisting  of  panoramas  and  illus- 
trations of  the  cultivation,  collection,  preparation,  with  specimens, 
etc.,  of  our  important  and  interesting  vegetable  drugs.  There  would 
be  other  buildings  illustrating  horticulture,  arborculture,  viticulture, 
viniculture,  agriculture,  geographical  and  fossil  botany,  as  well 
as  the  other  industrial,  ornamental  and  economical  sides  of  botany. 
It  must  be  apparent  that  an  exposition  of  this  kind,  botanically, 
would  be,  if  properly  managed,  of  a  highly  instructive  and  most 
interesting  character  to  the  world.  The  name  of  some  one  or  of 
some  event  of  world-wide  importance  would  be  necessary  to  arouse 
the  interest  in  such  an  Exposition.  Might  not  the  name  of  Linnaeus 
do  this?  Is  it  too  much  to  hope  that  the  next  World's  Exposition 
might  be  a  botanical  exhibition  and  called  the  World's  Linnaean 
Exposition,  to  be  held  beginning  May  23,  2007,  in  honor  of  the 
third  centennial  anniversary  of  the  birth  of  Linnaeus  ?

The  formula  for  Trituration  of  Elaterin  should  have  been  omitted 
as  the  general  formula  for  triturations  is  sufficient  and  more  exact 
in  the  directions. 
The  official  troches  as  a  class  are  sadly  neglected  by  the  medical 
profession,  and  from  a  pharmaceutical  standpoint  they  are  badly  in
