    Notes:
    This unusual artificial horizon attachment is a very early development of a gravity type instrument, preceding the bubble sextant. The artificial horizon is indicated by a pointer floating in pure water. It is designed to permit the use of the sextant when the true horizon cannot be seen due to fog, darkness or intervention of land. Since this instrument was developed before the use of electrical illumination, an oil lamp is provided for use at night.
