INTRODUCTION.
received    many    applications   for  Catalogues

~s    and  Cuts  of  our  Instruments,  we  have  issued  this  pam-
phlet,  pending  the  preparation  of  a  more  complete
Catalogue.
We  must  say,  however,  that  with  our  superior  facilities,
consisting  of  the  latest  and  most  improved  machinery  and
tools,  with  the  advantages  of  steam  power,  large  practical
and  technical  experience,  we  are  enabled  to  compete  with
the  best  makers  in  quality  of  work  as  well  as  in  prices.
To  our  patrons  who  have  favored  us  with  their  orders
we  give  our  sincerest  thanks  ;  and  to  our  patrons,  present  and
future,  we  give  our  word  never  to  cease  to  have  every  pos-
sible care  taken  in  order  not  to  allow  any  instrument  to  leave
our  Factory  unless  we  can  guarantee  its  perfection  in  every
particular  ;  and  we  say  with  some  complacence  that  our
Factory  has  the  means  to  compete  with  makers  of  world-
wide fame.
We  are  very  confident  that  hereafter  Western  Engineers,
Colleges,  and  other  Educational  Institutions  need  not  go
further  for  their  instruments  ;  for  in  prices,  as  well  as  in
quality,  we  are  enabled  to  compete  with  the  oldest  and  best-
known  factories  in  the  eastern  market.
