Famous quotes containing the word observed:

    To study the stars upon the wide, boundless sea, is divine as it was to the Chaldean Magi, who observed their revolutions from the plains.
    Herman Melville (1819–1891)

    Often on bare rocky carries the trail was so indistinct that I repeatedly lost it, but when I walked behind him I observed that he could keep it almost like a hound, and rarely hesitated, or, if he paused a moment on a bare rock, his eye immediately detected some sign which would have escaped me. Frequently we found no path at all at these places, and were to him unaccountably delayed. He would only say it was “ver strange.”
    Henry David Thoreau (1817–1862)

    Some facts should be suppressed, or, at least, a just sense of proportion should be observed in treating them.
    Sir Arthur Conan Doyle (1859–1930)
