Extract

The Rocks included under this head are those already described by Professor Phillips, in his paper “On Group of Slate Rocks in Yorkshire, between the rivers Lune and Wharfe, etc.” (Trans. Geol. Soc., 2nd Series, III. 1). Also by Professor Sedgwick, in his paper “On the Lower Palæozoic Rocks at the base of the Carboniferous Chain, between Ravenstonedale and Ribblesdale” (Quart. Journ. Geol. Soc. VIII. p. 35).

page 349 note 1 “Keld” is the term applied to the large springs socommon in limestone districts, where the water collected in the pot-holes and crevices of the rock runs out a full stream from a cave below. Prof. Sedgwick informs me that a similar word (“Kelda,” I think) is used to denote a similar phenomenon in Iceland.

page 355 note 1 The word “greywacké” as defined by MrForbes, (p. 229, sup. foot-note) would be a very useful term in this country. We want a name for the tough Silurian rocks which seem to be something between a grit, or sandstone and quartzite.—See Geol. Mag., Vol. III. p. 206, foot-note.Google Scholar
