Polymath 997
Having an unusually bad day with this one.
4d Pertaining to a type of surgery on bones (12) osteo?l?s?ic
16d A Shakesperean word for a woman selling a particular type of fruit (6-4) ?r?n?e-?i?e
I have a problem with 29 across - an archaic word meaning libidinousness.
I thought it was lustiness ( from last letters of - ethnical, Olympus, solidi, Navaronne ) but it can't be if 23d (for the last letter) is corsned (brread and cheese swallowed or stuck in the throat to determine innocencse or guilt)?
