  From  Webster's  Revised  Unabridged  Dictionary  (1913)  [web1913]: 
  Induction  \In*duc"tion\,  n.  [L.  inductio:  cf  F.  induction.  See 
  1.  The  act  or  process  of  inducting  or  bringing  in 
  introduction;  entrance;  beginning;  commencement. 
  I  know  not  you  nor  am  I  well  pleased  to  make  this 
  time,  as  the  affair  now  stands,  the  induction  of 
  your  acquaintance.  --Beau.  &  Fl 
  These  promises  are  fair,  the  parties  sure  And  our 
  induction  dull  of  prosperous  hope.  --Shak. 
  2.  An  introduction  or  introductory  scene,  as  to  a  play;  a 
  preface;  a  prologue.  [Obs.] 
  This  is  but  an  induction:  I  will  d?aw  The  curtains 
  of  the  tragedy  hereafter.  --Massinger. 
  3.  (Philos.)  The  act  or  process  of  reasoning  from  a  part  to  a 
  whole,  from  particulars  to  generals,  or  from  the 
  individual  to  the  universal;  also  the  result  or  inference 
  so  reached. 
  Induction  is  an  inference  drawn  from  all  the 
  particulars.  --Sir  W. 
  Induction  is  the  process  by  which  we  conclude  that 
  what  is  true  of  certain  individuals  of  a  class,  is 
  true  of  the  whole  class,  or  that  what  is  true  at 
  certain  times  will  be  true  in  similar  circumstances 
  at  all  times.  --J.  S.  Mill. 
  4.  The  introduction  of  a  clergyman  into  a  benefice,  or  of  an 
  official  into  a  office,  with  appropriate  acts  or 
  ceremonies;  the  giving  actual  possession  of  an 
  ecclesiastical  living  or  its  temporalities. 
  5.  (Math.)  A  process  of  demonstration  in  which  a  general 
  truth  is  gathered  from  an  examination  of  particular  cases, 
  one  of  which  is  known  to  be  true,  the  examination  being  so 
  conducted  that  each  case  is  made  to  depend  on  the 
  preceding  one  --  called  also  {successive  induction}. 
  6.  (Physics)  The  property  by  which  one  body,  having 
  electrical  or  magnetic  polarity,  causes  or  induces  it  in 
  another  body  without  direct  contact  an  impress  of 
  electrical  or  magnetic  force  or  condition  from  one  body  on 
  another  without  actual  contact 
  {Electro-dynamic  induction},  the  action  by  which  a  variable 
  or  interrupted  current  of  electricity  excites  another 
  current  in  a  neighboring  conductor  forming  a  closed 
  {Electro-magnetic  induction},  the  influence  by  which  an 
  electric  current  produces  magnetic  polarity  in  certain 
  bodies  near  or  around  which  it  passes. 
  {Electro-static  induction},  the  action  by  which  a  body 
  possessing  a  charge  of  statical  electricity  develops  a 
  charge  of  statical  electricity  of  the  opposite  character 
  in  a  neighboring  body. 
  {Induction  coil},  an  apparatus  producing  induced  currents  of 
  great  intensity.  It  consists  of  a  coil  or  helix  of  stout 
  insulated  copper  wire,  surrounded  by  another  coil  of  very 
  fine  insulated  wire,  in  which  a  momentary  current  is 
  induced,  when  a  current  (as  from  a  voltaic  battery), 
  passing  through  the  inner  coil,  is  made  broken,  or 
  varied.  The  inner  coil  has  within  it  a  core  of  soft  iron, 
  and  is  connected  at  its  terminals  with  a  condenser;  -- 
  called  also  {inductorium},  and  {Ruhmkorff's  coil}. 
  {Induction  pipe},  {port},  or  {valve},  a  pipe,  passageway,  or 
  valve,  for  leading  or  admitting  a  fluid  to  a  receiver,  as 
  steam  to  an  engine  cylinder,  or  water  to  a  pump. 
  {Magnetic  induction},  the  action  by  which  magnetic  polarity 
  is  developed  in  a  body  susceptible  to  magnetic  effects 
  when  brought  under  the  influence  of  a  magnet. 
  {Magneto-electric  induction},  the  influence  by  which  a  magnet 
  excites  electric  currents  in  closed  circuits. 
  {Logical  induction},  (Philos.),  an  act  or  method  of  reasoning 
  from  all  the  parts  separately  to  the  whole  which  they 
  constitute,  or  into  which  they  may  be  united  collectively; 
  the  operation  of  discovering  and  proving  general 
  propositions;  the  scientific  method. 
  {Philosophical  induction},  the  inference,  or  the  act  of 
  inferring,  that  what  has  been  observed  or  established  in 
  respect  to  a  part  individual,  or  species,  may  on  the 
  ground  of  analogy,  be  affirmed  or  received  of  the  whole  to 
  which  it  belongs.  This  last  is  the  inductive  method  of 
  Bacon.  It  ascends  from  the  parts  to  the  whole,  and  forms, 
  from  the  general  analogy  of  nature,  or  special 
  presumptions  in  the  case,  conclusions  which  have  greater 
  or  less  degrees  of  force,  and  which  may  be  strengthened  or 
  weakened  by  subsequent  experience  and  experiment.  It 
  relates  to  actual  existences,  as  in  physical  science  or 
  the  concerns  of  life.  Logical  induction  is  founded  on  the 
  necessary  laws  of  thought;  philosophical  induction,  on  the 
  interpretation  of  the  indications  or  analogy  of  nature.
