Of all the puzzles I do, I don't often get problems with this one, but need to confirm these:-
7 Down - "One line of mathematicians with popular appeal". (6)
I have I-O-I- (can only think of IRONIC or ICONIC)
8 Down - "Character in middle of manic state?" (6) N-T-E-
(Maybe NUTTER or NETHER?)
24 Across - "State of excitement that's less half-hearted! (5) -E-E-
(Surely FEVER?)
