His  predominating  opinions  were  that  a
better  scientific  training  was  necessary  for
the  practitioner  of  dentistry.  His  ideals,
to  which  may  be  added  a  ripe  experience
and  mature  judgment  plus  the  enthusiasm
and  vigor  of  his  younger  colleague,  Doctor
Chapin  A.  Harris,  were  without  doubt  the
most  potent  factors  in  creating  that  trinity
which  stands  now  as  the  distinguishing  in-
fluence in  American  dentistry.
Doctor  Harris  ( ISOCi-lSllO),  after  reach-
ing maturity,  pursued  the  practice  of  medi-
cine, surgery  and  dentistry  in  various  locali-
ties in  Ohio  and  part  of  the  time  as  an
itinerant  dentist,  making  favorable  impres-
sions wherever  he  traveled,  finally  locating
in  Baltimore.  Not  the  least  important
event  in  his  professional  career  is  the  work
he  accomplished  in  assisting  Doctor  Hay-
den,  aided  by  others,  in  establishing  the
first  dental  school  in  this  country,  the
Baltimore  College  of  Dental  Surgery.  This
institution,  incorporated  February  1,  1840.
with  five  students  in  attendance  during  the
first  session  is  the  prototype  of  American
schools  which  have  done  so  much  toward
building  character  into  American  dentistry.
Second  in  the  trinity  is  the  dental  jour-
nal. Transportation  and  the  modern  means
of  communication,  aided  by  utilizing  elec-
trical energy,  have  enabled  us  as  individu-
als to  learn  of  conditions  in  other  parts  of
the  world  in  the  briefest  spaces  of  time,
but  the  art  of  printing  has  been  the  great-
est single  factor  in  the  dissemination  of
knowledge  that  ever  existed.
