O
Objects of general censure
Obscured beneath the rubbish of the age
Obsessed with an overweening pride
Obstacles that are difficult but not insuperable
Obviously at variance with facts
Occasioned by direct moral turpitude [turpitude = depravity; baseness]
Oddly amenable to the proposed innovations
Often employed promiscuously
Ominous and swift days
Omitting all compliments and commonplaces
On a noble and commanding scale
On sure ground of fact
On the edge of great irritability
On the horns of a dilemma
One of life's ironical adjustments
One of the foreseen and inevitable results
One tissue of rashness, folly, ingratitude, and injustice
Openly flouted and disavowed
Oppressed by some vague dread
Organs of party rage and popular frenzy
Our opinions were diametrically opposed
Our vaunted civilization
Outward mark of obeisance and humiliation [obeisance = attitude of deference]
Overcome by an access of misery
Overshadowed by a fretful anxiety
Overwhelmed with reproach and popular indignation
