"Percolation" Quotes from Famous Books
 ... the framework of the stupendous rose-window over the grand entrance, and this, with other unsatisfactory symptoms observable here and there in the building, lend colour to the theory that the great chalk bed upon which the Cathedral stands may have been affected by the percolation of water from some deep trenches which, it seems, were dug near the northern and southern towers at the entrance of the Cathedral, during the year 1879, and unfortunately left open during the very inclement winter ...

Such metamorphic rocks occur in formations of all ages; ...
