Some of these last few are probably obvious - but I just can't see them!
184a) Chafe [G _ A _ E]. Think it is either GRATE or GRAZE, not sure which.
232d) Gentle movement [_ R _F T]. Guessing it's DRIFT, but want to be certain.
299d) Conferring [E _ _ _ _ I N G]
311a) Slowest to arrive [T A _ _ _ _ S T]. Tardiest?
325a) Milksop [_ _ _ _ L _ N _]
357a) Tense (5, 2) [_ _ E _ _, _P]
Going down is Proficiently [A B _ _]. Think that is ABLE, which puts the E in the wrong place for SEIZE. Also going down is Forceful [H A _ _]. Not sure what that is. Could be HARD? If if is then it makes Tense (5, 2) [_ _ E _ _, _ P],(assuming the E is correct, which it might not be).
