I n a paper by myself “On the Waterstone Beds of the Keuper in Somerset and Devon”* a sketch was given of the chief geological features of the coast from Culverhole Point to Littleham Bay, to the west of the Budleigh-Salterton pebble-beds. Since writing that paper I have found pseudomorphous crystals of salt a short distance to the west of Sidmouth, at Windygate, but have not found them to the west of Littleham Bay. The following pages contain an outline of the geology between that Bay and Maidencombe, or Minnicombe, near Torquay. The chief characteristic features are the beds in which Murchisonite occurs in the higher part, and the conglomerate beds with limestone in the lower part of the series. The last-named beds are specially noticed in Conybeare and Phillips's ‘Outlines of the Geology of England and Wales’ (page 293). It is there stated that the fragments in the breccia between Dawlish and Teignmouth consist of granitic and porphyritic rocks in many varieties, greywacke, or compact sandstone, and Lydian stone, and calcareous rocks with and without organic remains. These fragments, it is stated, may be regarded as being derived from the adjacent rocks at Babbicombe, Chudleigh, Ashburton, and Dartmoor. In the list of granitic and porphyritic fragments those of felspar are mentioned, and these both in the rocks of which felspar is a component part, and in detached crystals; these for the most part are the opalescent crystals known as Murchisonite. Murchisonite possesses a third cleavage in addition to the two
