    From Kelly's Spherics, 1796:
    "other ingenious [graphical] methods have been since contrived, but the most
    approved performance of th graphic kind is that lately executed by Mr.
    Margetts; a work of great labour, ingenuity, and correctness."

    He doesn't say, 'run out and buy it'. Maybe he should have! Instead, he
    offers a simple graphical solution of his own.

    Ken, you wrote:
    "Did Nathaniel Bowditch become famous because he had made a simpler method
    for clearing lunars?"

    Not so much, I would say. In the 20th century, the importance of his "new
    method" has been significantly exaggerated in various accounts of his life. But
    his streamlined method, the one I have called "Bowditch's Principal Method"
    was definitely less tedious and probably saved a minute of work on each
    clearing. Every little bit helps.
