Some Geological Notes on Central France
Miss M. S. Johnston—Geological Notes on Central France. 59' about 6 X 6 X 2 feet. The surfaces of these two large slabs have been deeply scored by running water, and pierced in all directions by rootlet and other holes.—C. D. S. 1896. In the Proc. Geol. Assoc., vol. xiv, p. 158, Mr. Allen Brown states that " a large tabular water-worn Sarsen, and a portion of it broken off in Quaternary times," were found in the gravel at Hanwell; and that another Sarseu occurred at the base of the gravel at the back of Hanwell Station. 1900. In " The Pits," old gravel workings, an allotment, now- wooded, belonging to William Sherborn, Esq., and formerly part of Bedford Common, Middlesex, there is a large Sarsen, measuring about 5x5x2 feet, from one end of which a block about a foot thick was removed.—C. D. S. 1900. In front of the roadside inn (the "Griffin") at Totteridga or Whetstone, near Highgate, stands a short thick Sarsen, about 25 inches high above ground, and 20 inches broad at top and 18 inches below. It is locally said to be as large again below the surface ; and to have been used as a ' whetstone ' for their weapons by the soldiers going to the Battle of Barnet (1471).—A. O. Brown. 1900. Horace B. Woodward describes a Greywether from the Gravel of South Kensington, in the GKOL. MAG., December, 1900, p. 543 (with figure). It measures 3 ft. 10ins. X 3 ft. Sins. X 2 ft., and is in many respects analogous to the specimen from Bayswater described above.
