    I found a facsimile of the original article where Planck gives a value for h
    (except that in May 1899 he was calling it b, instead of h.)

    Here is the exact page where he gives his estimate of the value of h, or rather "b" as he calls it.

    6.885 x 10-27 cm2gr/sec

    pretty close. lovely. slightly mysterious. May 18 1899
    no time to comment, have to go out.
