    Re: Latitude by two altitudes and the elapsed time

    Yes  dear Geoffrey, time is gold.

    nowadays,  

    Latitude by two altitudes and the elapsed time, or double altitudes method for latitude, is useless.

    I have pointed it out in terms of historical interest.
    Lax was the author of other publications like the Appendix to "Nautical Almanac & Astronomical Ephemeris" by Lax
