possible,  and  yet  strong  enough  in  all  its  parts  to  be  durable  and 
powerful  enough  to  resist  a  pressure  equal  to  five  times  that 
required. 
The  arrangement  of  the  machine  is  readily  understood  from  the 
cut ;  it  weighs  sixty  pounds,  occupies  a  counter  space  of  six  by 
twelve  inches  and  stands  twelve  inches  high  ;  the  movements  are 
positive  and  automatic,  having  an  adjustment  whereby  the  feed  can 
be  regulated  to  the  part  of  a  grain,  and  the  pressure  so  as  to- 
make  the  tablets  of  any  degree  of  hardness.  The  feed-can  being 
nicely  adjusted  on  the  bed-plate  prevents  any  waste  of  material, 
and  is  so  shaped  with  an  inside  agitator  that  makes  the  feed  so  posi- 
tive and  regular  that  when  the  machine  is  set  for  a  given  number 
of  tablets,  the  last  one  will  be  as  accurate  and  perfect  as  the  first 
one.  The  bed-plate  moves  but  a  short  distance  and  carries  the 
bottom  die  under  the  feed-can  for  supplies,  and  to  the  plunger, 
where  the  material  is  compressed  and  the  tablet  ejected.  There 
are  four  sets  of  dies,  made  of  the  best  steel,  highly  polished,  pro- 
ducing tablets  well  shaped,  and  with  edges  perfect  as  possible  to 
make  them.  The  fly-wheel  is  of  sufficient  diameter  to  make  its 
running  easy  to  the  operator.  The  machine  is  neat  in  appearance 
being  ornamented  with  nickel  trimmings,  and  nicely  painted  in 
brown  and  gold. 
In  conclusion,  the  writer  ventures  to  express  the  hope  that  he  has
