From an Eight Chain Thru (or Parallel R-H Waves).
Right Pull By; 
Outsides Courtesy Turn and Veer Left as the Centers
  Step To A L-H Wave, Very Centers Left-face U-Turn Back (placing
  R-H on adjacent End's back), Courtesy Turn and As Couples Extend.
Ends in Parallel R-H Two-Faced Lines.
Notes:
- 
The Courtesy Turn movement for the new Centers (after the R-H Pull
    By) is sometimes described as 1/4 Out; Courtesy Turn & 1/4 more.
    We dislike this definition for 2 reasons:
- 
The original Outside Belle's part is somewhat awkward because
      there is first a 1/4 Out (to the Right) and then Courtesy
      Turn (to the Left) 3/4, instead of just a smooth 180° Courtesy Turn.
- 
If you advance into C3, the caller may call a Left Chain The
      Square in which case we believe it is easier to remember to have
      the new Centers Step To A R-H Wave & then the Very
      Centers always turn the Ends.  If, instead, you were to 1/4
      Out, you can easily become confused as to who turns who.
Hints:
- 
After the new Centers Step To A Wave, it is always the Centers of
    the Wave that take the Ends back to where the Ends came from.
