the  large  display  of  fine  chemicals  exhibited.  The  most  unique  is 
the  group  of  cocaine  crystals,  many  of  which  are  over  3  inches  in 
length.    The  firm's  initials  are  done  in  crystals  of  terpinhydrate. 
In  the  Electricity  Building,  as  stated,  will  be  found  the  German 
chemical  exhibit.  The  Germans  have  intended  to  make  this  an 
educational  exhibit,  and  commercialism  had  to  take  a  back  seat. 
The  individual  firm  is  not  in  evidence  as  in  the  British  section.  All 
firms  have  pooled  their  interests,  and  make  a  great  display  where 
duplication  of  same  subjects  is  unknown.  They  have  succeeded 
remarkably  well. 
The  time  when  chemists  worked  in  the  dark  cellars  and  were 
more  or  less  associated  with  the  Evil  One  by  the  ignorant  populace, 
is  shown  by  actual  utensils  of  an  alchemist's  laboratory  as  borrowed 
from  the  great  Niirnberg  collection  of  things  alchemistic.  In  a  dark 
cellar-like  grotto,  we  see  the  walls  and  ceiling  hung  with  crocodiles, 
salamanders,  snakes,  turtles  and  the  like.  Old-fashioned  furnaces, 
with  retorts  of  a  peculiar  green  glass  and  with  helms  of  the  same 
material,  and  also  adapters  and  receivers  of  various  forms,  show  with 
what  these  active  workers  performed  the  operations  of  distilling. 
On  the  floor  are  spread  ores  and  gangues  as  found  in  Freiberg.  Old 
works  of  the  period  are  found  in  the  general  library  of  the  exhibit. 
Opposite  the  alchemist's  laboratory  is  that  of  Liebig's  at  Giessen. 
Here  are  the  long-armed  balances  he  used,  the  furnace  and  bulbs 
used  in  combustion  analysis  that  bear  his  name.  The  many  com- 
pounds prepared  in  the  Giessen  laboratory  during  his  stay,  are 
arranged  along  the  walls.  In  looking  at  the  little  Liebig  had  to 
work  with,  and  contrasting  that  with  what  is  found  in  many  of  the 
State  institutions,  it  is  forcibly  brought  home  that  some  men  may  do 
much  with  very  little,  and  they  that  have  very  much  seem  to  do  little. 
Synthetic  perfumes  in  pint  bottles,  such  as  ionone,  rose,  etc.,  an 
entire  case  of  so-called  synthetics,  many  fine  inorganic  compounds, 
thousands  of  dyes  and  the  various  organic  compounds  of  technical 
or  theoretical  importance,  make  up  a  large  part  of  the  exhibit. 
Historical  work  is  illustrated  by  samples  of  that  extremely  rare 
element,  Germanium,  as  separated  by  the  celebrated  Freiberg 
chemist,  Clemens  Winckler.1    Also  the  first  contact  appliance  for 
1  We  have  almost  as  fine  a  sample  in  our  owu  collection — a  present  from 
Winckler.
