"This  series,  besides  affording  popular  but  sound  instruction  on  scientific  subjects,  with  which
the  humblest  man  in  the  country  ought  to  be  acquainted,  also  undertakes  that  teaching  of  'Com-
mon Things  '  which  every  well-wisher  of  his  kind  is  anxious  to  promote.  Many  tliousand  copies  of
this  serviceable  publication  have  been  printed,  in  the  belief  and  hope  that  the  desire  for  instruction
and  improvement  widely  prevails  ;  and  we  have  no  fear  that  such  enlightened  faith  will  meet  with
disappointment." — Times.
"  A  cheap  and  interesting  publication,  alike  informing  and  attractive.  The  papers  combine
subjects  of  miportance  and  great  scientific  knowledge,  considerable  inductive  powers,  and  a
popular  style  of  treatment." — Spectator.
"  The  '  Museum  of  Science  and  Art '  is  the  most  valuable  contribution  that  has  ever  been
matle  to  the  Scientific  Instruction  of  every  class  of  society." — Sir  DAVID  BREWSTER,  in  the
North  British  Review.
"  Whether  we  consider  the  liberality  and  beauty  of  the  illustrations,  the  charm  ot  the  writing,
or  the  durable  interest  of  the  matter,  we  nu;st  exiiress  our  belief  that  there  is  hardly  to  be  found
among  the  new  books  one  that  would  be  welcomed  by  people  of  so  many  ages  and  classes  as  a
valuable  present," — Examiner.
