Tyndall (1872, p.154) "So natural was the
association of ice and cold that even celebrated
men assumed that all that is needed to produce a
great extension of our glaciers is a diminution
of sun's temperature. Had they gone through the
foregoing reflections and calculations, they
would probably have demanded more heat instead of
less for the production of "glacial epoch"."
