The Oolites of the Cave District [a comprehensive account of the Jurassic 

 strata which strike N.N. W. from the Humber in the neighbourhood of Brough 

 to near Market Weighton ; section of the ' Town Quarry ' at North Newbald 

 given, with fossils obtained ; section of the Kellaways Rock with overlying 

 Oxford Clay in cutting of Hull and Barnsley Railway described ; the clay 

 exposed in the railway near Weedley, by its aspect and the Belemnites it 

 yielded, thought to be Neocomian ; the lacustrine deposit at Rielbecks noted].

Joints cutting through Pebbles [The conglomerate at the base of the Mountain 

 Limestone in North-West Yorkshire is intersected by joints, which cut quite 

 cleanly through the included pebbles, even those of quartz. Localities for 

 observation : mouth of Crummock Dale, just below Norber Brow, and higher 

 up the dale at Crummock Beck Head]. Nat., April 1886, p. 102.

Bursting Rock Surfaces [the author describes some curious phenomena at 

 Dent Head quarries and Ribble Head tunnel ; in cutting the tunnel a thin 

 layer of hard rock was left as a floor over the underlying shale ; the shale, 

 yielding to the superincumbent weight at the sides, exerted a powerful force 

 on the overlying thin bed, so that pieces of the latter burst off with a loud 

 noise]. Geol. Mag., Nov. 1887, dec. iii. vol. iv. pp. 511-512.
