27 A. Malignant spirit- everything's ending in insensibilty (4) ?i??
(I see 'ginn' - but can't see how it fits the second half of the clue)
33 A. Moon of Neptune with sulphur and carbon would wreck spacesuit (7) ?a?????
(I think 'larissa' might be a moon, but again I've no real idea how the clue works)
