logical resemblance to the Carboniferous Limestone of the Mendips. 

 Observes that the mass is part of a dome or fold, and considers that it 

 is Carboniferous — a fact which strengthens our hopes of finding coal 

 beneath the Somersetshire marshes. H. V>. W.

Eresh excavations have been made in the Glacial deposits ; the 

 striated limestone boulders are chiefly blue or black, like the top beds 

 of the Carboniferous Limestone near Penyghent, not like the white 

 limestone in which the cave is excavated. Deposits of sand and 

 laminated clay occur at the back of the boulders. Eresh evidence is 

 given to prove that the striated boulders overlie the cave-earth ; that 

 the boulders were deposited by the ice-sheet; consequently that the 

 cave-earth is older than the ice-sheet. Eemains of the Pleisto- 

 cene fauna are found in many caves in the N. of England, but not in 

 the gravels of the open country, where probably glaciation has 

 destroyed them. Details of the w^ork, and a summary of the physical 

 changes of which the cave affords evidence, are given. W. T.
