The instructions for bars 9-16 have changed more than once over the years *(details courtesy of the MiniCrib team)*.
The original publication and some revised editions of Book 9 say the three couples cross "passing right shoulder".
The publication "101 Scottish Country Dances" and a number of subsequent editions of Book 9 changed that to cross "giving right hands".
In the latest RSCDS edition of Book 9 (published in 2009) they just cross "passing by the right".
The 2013 edition of the RSCDS manual is more explicit, saying that while the original specified no hands, these days usually hands are given.
