Apologies for my rant yesterday. I am used to finishing these unaided, so maybe there were some sour grapes after all :)
I'm enormously grateful to an extremely clever and helpful friend for putting me out of my misery on the two missing phrases, and they serve only to endorse dr b's point, that unless you have the linguistic expertise or book edition in question, (or a boiler room chock-full of googling monkeys), don't necessarily expect to complete the puzzle, even if you�ve solved all the clues.
In my irritation yesterday I went for a more apposite anagrammatic title:
Idiotic sham by Doc
Or, more generously,
Didacticism? Oh boy!
But I�ve mellowed overnight. Congratulations to all those who have completed it
