    Re: How Worsley Navigated
    From: Brad Morris
    Date: 2009 Feb 26, 11:07 -0500

    I surrender George.  With the dispute in maps, I wanted to see the
    navigational log to attempt to resolve the dispute.  I retract my
    speculation.  Yes, I have read the books, I just haven't referenced them
    recently.
    
    I wish I knew the location of the Caird, so I could obtain better images
    of the sextant.  If we accept the image of the sextant used, then I can
    tell you that there almost no doubt in my mind that the sextant I have
    is the twin of the one used.  Further, there are two components missing,
    for which we can see spaces in the box, now vacant.  The first component
    missing is a shade that attaches to the back of the telescope tubes.  It
    goes into a slot on the right hand wall.  The greatest angle clamp and
    one of the two eye shades are there.  The gap is visible right beyond it
    for that second eye shade.  The other component missing from the sextant
    used is an inverting scope.  It is held in the block of wood with the
    large round hole, just over the index mirror.  I can see the other
    components are present.  I can see nothing else missing.  Note that the
    binoculars are standing in the case at the mounting location, but not
    held in the case as designed.  
    
    Now that I am done "contemplating the angle of my knob" (hehehe), I can
    easily give you one of the reductions, attached herein.
    
    Best Regards
    Brad
