Apparatus  Stand. 
73 
the  stand  was  loaded  with  apparatus,  as  shown  in  the  engraving,  very 
little  inconvenience  was  felt  in  using  the  bottles  on  the  shelves.. 
The  stand  was  placed  on  a  semi-circular  table  65  inches  long,  28 
inches  wide  in  the  centre,  and  33  inches  high;  the  lower  part  of  this 
table  is  divided  into  three  very  convenient  closets,  and,  as  shown  in  the 
•cut,  the  top  is  left  entirely  free,  and  may  be  used  as  a  writing  table. 
The  table  and  closets  are  neatly  made  of  black  walnut,  and,  with 
the  stand  and  percolating  apparatus  it  contains,  are  rather  an  ornament 
to  the  prescription  department,  besides  furnishing  ocular  evidence  of 
the  home  manufacture  of  fluid  extracts,  etc. 
The  various  parts  are  all  extremely  simple,  and  I  have  endeavored 
to  make  the  following  description  of  them  plain  enough  to  enable  any 
machinist  to  make  the  stand. 
The  clamp  is  the  most  important  part;  it  is  made 
of  brass,  and  is  2  inches  long,  ij  inch  wide  and  i| 
inch  high,  with  a  \  inch  elevation  opposite  the  slot. 
The  slot  is  just  large  enough  to  allow  the  clamp  to 
be  slipped  on  the  iron  rods;  the  clamp  also  contains 
two  smaller  holes,  bored  all  the  way  through,  for  the 
stems  of  the  rings  and  the  small  ends  of  the  rods. 
Cratus  Stan^P"     ^  ls  firmly  m  place  by  means  of  thumb-screws 
— a  separate  cut  is  given  showing  it  more  in  detail 
than  could  be  done  on  the  large  illustration. 
The  remaining  parts  are  two  iron  rods,  nine-sixteenths  of  an  inch  in 
diameter  and  48  inches  long  ;  a  i-inch  screw  is  cut  on  one  end  of  each 
of  these  rods. 
Four  iron  rods  of  the  same  diameter  and  42  inches  long ;  two  inches 
of  each  end  of  these  four  rods  is  turned  down  on  a  lathe  to  five-six- 
teenths of  an  inch  diameter. 
Two  2J  inch  circular  brass  feet,  to  screw  on  the  lower  ends  of  the 
48-inch  rods. 
Two  pieces  of  brass  J  inch  thick,  ij  inch  wide  and  7|*inches  long, 
with  a  round  hole  in  one  end  to  slip  over  the  top  of  the  48-inch  rod, 
and  a  square  hole  in  the  other  end,  through  which  a  screw  bolt  is 
passed  to  secure  it  to  the  shelf.  Should  there  be  no  shelving  where 
the  stand  is  set  up,  an  L-shaped  bracket  must  be  used  instead  of  this 
straight  piece. 
The  rings  are  made  of  five-sixteenth  inch  iron,  and  are  from  1  to  10
