    Mecca - thanks
    From: R.H. van Gent
    Date: 2000 Aug 26, 3:20 AM

    Dear all,
    
    I am most grateful for the trouble that some of you have done for
    responding to my query.
    
    >From the jpg map of Mecca kindly sent to me by Roger Derby I measured
    the following position of the Kabah, the sacred temple of Mecca:
    
      Lat. = 21� 25' 30" N., long. = 39� 49' 22" E.
    
    Kamil Abdali's position, kindly provided by prof. Richard Langley, was:
    
      Lat. = 21� 25' 24" N., long. = 39� 49' 24" E.
    
    The longitude agrees nicely, though the latitude differs a bit more than
    one would expect.
    
    My interest in this matter stems from my research in a determination
    secretly carried out by N. Scheltema, the Dutch consul of Djedda, and
    his Muslim assistant A. Salim in the winter of 1910/11 that resulted in:
    
      Lat. = 21� 25' 18" N., long. = 39� 50' 59" E.
    
    The large difference in longitude stems from the fact that only the
    longitude difference between Mecca and Djedda was actually measured,
    while the longitude of the latter was adopted from the British Admiralty
    charts of that period.
