    Greg, Gary,

    I rummaged in my mind where I had last seen my graphical
    log() table. It was by an Austrian engineer, Anton Tich, I thought.

    Well, I found it and another one amongst my books.
    I had  forgotten about the second. It is by far the better one:

    "A Graphic Table Combining Logarithms and Anti-Logarithms"
    by LaCroix and Ragot

    It has actually 2 tables, one with 5 digits, the other one with 4 digits.
    The last one covers just 6 pages. I have attached a copy of the latter
    plus 2 pages of intro.

    Tell me what you think.

    Hanno

    PS:  3 more Vedics, 2 correct, done at 11pm.
