DICTIONAEY  OF  MANUFACTUEES,  MINING,  MACHIN-EEY,
  AND  THE  INDÜSTEIAL  AETS.  By  George  Dödd.
This  work,  a  small  book  on  a  great  subject,  treats,  in  alphabetical  arrangement,
  of  those  numerous  matters  which  come  generally  within  the  ränge
of  manufactures  and  the  productive  arts.  The  raw  materials—animal,  vegetable,
  and  mineral—whence  the  manufactured  products  are  derived,  are  succinctly
  noticed  in  connection  with  the  processes  which  they  undergo,  but  not
as  subjects  of  natural  history.  The  operations  of  the  Mine  and  the  Mill,  the
Foundry  and  the  Forge,  the  Factory  and  the  Workshop,  are  passed  under  review.
  The  principal  machines  and  engines,  tools  and  apparatus,  concemed  in
manufacturing  processes,  are  briefly  described.  The  scale  on  which  our  chief
branches  of  national  industry  are  conducted,  in  regard  to  values  and  quantities,
is  indicated  in  various  ways.
