For the Geological Section, its president and leader, the 

 Rev. E. Maule Cole, M.A., F.G.S., conducted a party of ladies and 

 gentlemen, in the first instance, to the quarries at Westow, where the 

 Millepore, or Whitwell Limestone of the Lower Oolites has been 

 largely quarried on both sides of the road to Pocklington. The 

 limestone was found to be intensely oolitic in structure, most of the 

 grains being globular or oval, but a few curiously elongated. The 

 blocks, as usual, were blue-hearted inside, very similar to the beds at 

 North Cave, the outer drab-coloured coating, several inches thick, 

 being due to oxydation. Several fossils were obtained, amongst them 

 a Gervillia, Lima, Pecten lens and fibrosus^) small Phasianetla, 

 Isocardia, and Cardium, the so-called 'Millepore' not being found. 

 Crossing the Abbey Lands of Lower Lias, the party next proceeded 

 to a spur of the Oolites, running from Gaily Gap to Leavening. 

 The latter village stands on a terrace of Lower Calcareous Grit, resting 

 on Oxford Clay, and supported by Kellaways Rock, which is visible 

 just below the village on the left. Above the village a beautiful 

 limpid stream of water was seen, issuing from the base of the Chalk, 

 and it was pointed out by the leader that similar streams are frequent 

 all round the outer margin of the Wolds, whilst on the inner or 

 Eastern side, only two are to be found, viz., at Duggleby, and at 



Nov. 1S89.
