Abstract
The first of this series of papers, that on the “Fossil Plants collected during the sinking of the shaft of the Hamstead Colliery, Great Barr, near Birmingham,” was published in 1888, and the second, dealing with the “Fossil Flora of the Coal Field of the Potteries,” in 1891.Since that date the North Staffordshire Coal Field has been re-surveyed by members of the Geological Survey, and the result of this re-examination of the geology of the Potteries Coal Field was the classification of the strata into several well-defined groups.
