The hungry curiosity of the mind
The idiosyncratic peculiarities of thought
The idle chatter of the crowd
The immediate tyranny of a present emotion
The inaccessible solitude of the sky
The incarnation of all loveliness
The incoherent loquacity of a nervous patient [loquacity = very talkative]
The indefinable air of good-breeding
The indefinable yearning for days that were dead
The indefinite atmosphere of an opulent nature
