{147} Mr. R. Mallet remarks ( Quarterly Journal of Geolog. Soc. vol.
xxxiii., 1877, p. 745) that the extent to which the ground beneath the
foundations of ponderous architectural structures, such as cathedral
towers, has been known to become compressed, is as remarkable as it is
instructive and curious. The amount of depression in some cases may be
measured by feet. He instances the Tower of Pisa, but adds that it was
founded on dense clay.
