plate  a  square-shouldered  screw  passes  and  is  screwed  in  until  it 
presses  the  plate  close  to  the  side  of  the  board,  but  still  permits  it  to 
move  easily ;  through  the  other  slot  in  each  plate  a  set  screw  passes 
and  enters  the  screw  plate  before  mentioned  ;  when  the  plates  have 
been  adjusted  to  a  given  height,  the  set  screws  are  turned  until  they 
prevent  any  motion  of  the  plate.  After  the  lozenge  mass  has  been 
prepared  it  is  weighed  and  the  weight  is  then  divided  by  the  num- 
ber of  lozenges  ordered ;  the  mass  is  made  of  the  thickness  thought 
D 
to  be  right  by  the  operator,  the  cutter  applied,  and,  if  the  weight 
agrees  with  that  ascertained  by  dividing  the  entire  quantity,  the 
work  proceeds  at  once,  but  if  too  heavy  the  guides  are  lowered,  or 
if  too  light  they  are  raised  until  the  proper  weight  is  attained. 
The  cut  illustrates  the  apparatus  very  fully.  A  is  the  board, 
seen  from  above.  B  is  a  side  view.  C  C  slides  in  place.  C  a 
slide  detached  to  show  the  slots,  the  front  one  should  be  ruled  to 
divisions  of  the  3  2d  of  an  inch.  D  the  set  screws,  one  in  place 
and  the  other  detached.
