  Mr. 
  Taudin 
  Chabot: 
  Gyrodynamical 
  Solution 
  of 
  the 
  

  

  forms 
  tried, 
  it 
  is 
  gyrodynamic 
  ; 
  I 
  might 
  therefore 
  call 
  the 
  

   instrument, 
  in 
  distinction 
  from 
  the 
  (jyrostatiG 
  compass, 
  a 
  

   gyrodynamiG 
  compass. 
  

  

  The 
  development 
  of 
  the 
  idea 
  obviously 
  transforms 
  the 
  

   ill-fated 
  vertical 
  axis 
  into 
  a 
  horizontal 
  axis, 
  which 
  expe- 
  

   riences 
  no 
  complete 
  rotation 
  as 
  before, 
  but 
  only 
  periodic 
  

   oscillations 
  of 
  extremely 
  small 
  amplitude. 
  Further 
  details 
  

   are 
  afforded 
  by 
  the 
  following 
  explanation, 
  with 
  the 
  help 
  of 
  

   the 
  description 
  of 
  a 
  model.

  The 
  principal 
  axis 
  F 
  of 
  the 
  model 
  (see 
  fig. 
  1) 
  cuts 
  at 
  an 
  

   angle 
  (90 
  —
