The third NINE, undivided, shows that action taken by its subject will be evil. Though he be firm and correct, his position is perilous. If the change (he contemplates) have been three times fully discussed, he will be believed in.
'The change (contemplated) has been three times fully discussed:' - to what else should attention (now) be directed?
