ture  of  the  Exhibition,  including  a  number  of  collections  from  abroad, 
among  which  that  of  Messrs.  Gehe  ^  Co.,  of  Dresden,  Saxony,  was  the 
most  interesting,  both  for  the  rarity  of  the  specimens  and  their  variety. 
Their  collection  included  vegetable  and  chemical  drugs,  essential  oils, 
fixed  oils,  powders,  extracts  and  "  concised  drugs,",  a  class  of  prepara- 
tions unknown  here,  in  which  aromatic  woods  and  roots  are  mechanically 
cut  into  square  and  globular  pieces  of  small  size,  each  being  about  a 
dose — such  as  rhubarb,  sassafras,  liquorice,  orris,  marshmallow,  calamus, 
etc.  Among  the  essential  oils  were  those  of  sandal  wood,  calamus, 
patchouli,  matico,  ginger  root,  coriander,  mustard  and  others.  Croton 
oil  extracted  by  benzine  oil  was  a  speciality  among  the  fixed  oils. 
Among  the  organic  principles  we  noticed  several  alkaloids,  koussin, 
digitalin,  jalapin,  caifein,  cantharidin,  etc. 
McKesson  Sf  Robbins,  of  New  York,  had  a  very  excellent  collection  of 
crude  drugs,  well  selected,  comprehensive,  valuable,  and  thoroughly  well 
exhibited,  which  has  much  to  do  with  the  effect  of  such  specimens  on  the 
visitors. 
Other  exhibitors  were  Messrs.  Neergaard,  of  New  York,  Henshaiv 
Bvigham,  of  Boston,  Hurlhutt  Sr  Edsell,  of  Chicago,  P.  W.  Bedford,  W.

Chemicals  were  well  represented.  As  usual,  the  most  brilliant  display 
was  made  by  Powers  Weightmayi,  of  Philadelphia,  whose  collection  in- 
cluded 220  specimens,  some  of  which  were  of  great  value  and  size  ;  the 
opium  and  cinchona  alkaloids  were  splendidly  illustrated,  and  general 
chemicals,  liquid  and  solid  very  thoroughly  represented. 
G.  Mallinckrodt  Sf  Co.,  of  St.  Louis,  came  next  in  the  variety  and 
beauty  of  their  display,  especially  in  liquid  chemicals.  Rosengarten  ^
