ResumoTHE question whether the Permian Shell Limestone Bryozoa Reef of the Middle Magnesian Limestone exists below the Upper Magnesian Limestones in the Hartlepool district was answered in the affirmative about two years ago, when a boring was sunk to a depth of 225 feet at West Hartlepool Waterworks (W on the sketch-map).
