In the Midland Counties the rocks mapped as Permian are considered on all sides, if Permian at all, to belong to the Lower or Rothliegende series; we need not therefore stop to discuss them at any great length here. The chief authorities are Mr. Howell and the late Prof. Jukes. In Warwickshire the case is a simple one: there is, according to Mr. Howell, a general unconformity of the rocks called Permian with the Triassic strata which lie above them. In the Staffordshire area the case is somewhat different. After a careful perusal of Mr. Jukes's Memoir, I fail to find that his survey of the district enabled him to furnish any direct evidence of the unconformity between the Permians and the Trias, in the existence of which he expresses his belief in the text.
