Famous quotes containing the words composition of, composition and/or flora:

    The proposed Constitution ... is, in strictness, neither a national nor a federal constitution; but a composition of both.
    James Madison (1751–1836)

    Boswell, when he speaks of his Life of Johnson, calls it my magnum opus, but it may more properly be called his opera, for it is truly a composition founded on a true story, in which there is a hero with a number of subordinate characters, and an alternate succession of recitative and airs of various tone and effect, all however in delightful animation.
    James Boswell (1740–1795)

    A man’s interest in a single bluebird is worth more than a complete but dry list of the fauna and flora of a town.
    Henry David Thoreau (1817–1862)
