I am confused by an apparent non-word in the start of the instruction "shade -hume and initials....". The h is from (h)in(g)es = Ines u is from fe(u)d ; m is excess from germ = erg ; and the e from (e)metic. I cannot work out the missing first letter. I have then found six other places to match with the lower highlighted OC (is that the seventh ?). So what about the highlighted AG above (Arnos Grove) ? Any hints/clues greatly appreciated.
