Famous quotes containing the word case:

    “I am absurdly fearful about this voyage. Various little omens have combined to give me a dark feeling.... Perhaps we shall live to laugh at these. But in case of mishap I should perish with my husband and child, perhaps to be transferred to some happier state.”
    —Margaret Fuller (1810–1850)
