Kelvin and the Age of the Earth

[Brian Blais <bblais@BRYANT.EDU>]

Hello,

    I was wondering if anyone could point me to Kelvin's derivation of the age
    of the Earth?  I see references to it many places, but no actual
    derivations.  He has a similar calculation of the age of the Sun.  I have
    combed the web, with no success, and thought that someone on the list
    might have a ready reference.


               thanks,

                    Brian Blais
