I shot myself in the foot early on by thinking 33d was sexton...so went off looking at the totally wrong text!
Got it now and the other three characters.
Stuck on the top left hand corner now. Is 10 ac Honorific? (I'm praised for moving to retain university committee.) It doesn't feel right but I cant make anything out of it. I have only these letters. ?????I?I?
2dn. Person's amazingly cute rear. (8) ???????E.
Is it an anagram of cute rear = creature?
