Famous quotes containing the words air and/or hot:

    The air split into nine levels,
    Some gift of tongues of the whistler
    James Dickey (b. 1923)

    For do but note a wild and wanton herd
    Or race of youthful and unhandled colts
    Fetching mad bounds, bellowing and neighing loud,
    Which is the hot condition of their blood;
    If they but hear perchance a trumpet sound,
    Or any air of music touch their ears,
    You shall perceive them make a mutual stand,
    Their savage eyes turned to a modest gaze
    By the sweet power of music.
    William Shake{peare (1564–1616)
