“ Young and Bird (1822) were first in the field, and applied the provincial name of Dogger to the bed immediately above the Lias. They observe (p. 123) that "one of the most remarkable beds in the series of Sandstone, Shale, and Coal is the lowest member of it, viz. the bed called the dogger, which lies immediately over the alum schist. This is a singular species of conglomerate, assuming a variety of forms." From the measurements given at p. 125 it is evident that they were unacquainted with the fine development occurring at Blea Wyke (Blue Wyke) to which Phillips drew attention in 1829. ”
