There is an extraordinary variability of web-accessible materials, even
from academic sources on the topic of Kelvin's Earth age estimate.
 If you will persevere with this URL to fig 1.10, you will find a
respectable treatment of Kelvin's method, which begins with the observation
of increase of temperature with depth in mines in graphical form, of which
there were plenty in Victorian Britain.
