An incursion of the loud, the vulgar and meretricious [meretricious = plausible but false]
An inexplicable and uselessly cruel caprice of fate
An inexpressible fervor of serenity
An ingratiating, awkward and, wistful grace
An inspired ray was in his eyes
An instant she stared unbelievingly
An intense and insatiable hunger for light and truth
An intense travail of mind
An obscure thrill of alarm
An odd little air of penitent self-depreciation
