Discussion. 



Mr, H. B. W^ooDWARD remarked that the Author had added 

 largely to the information obtained by "Mr. Fox-Strangways and 

 himself. The recognition of the zone of Ammonites ibex was 

 interesting, as it had so rarely been identified elsewhere in 

 England ; bnt it may be admitted that the non-discovery of 

 particular fossils is no proof of the absence of any zone, or 

 of the non-representation of any hemera. 



Referring to the occurrence of certain limestoce -nodules of 

 fantastic shapes in the an7^«^lt^-beds, he suggested that they 

 had been formed in sediment which had been slowly deposited 

 and wherein segregation was comparatively free, whereas the 

 smooth lenticular nodules found in a succeeding mass of clays 

 might have been formed under shghtly greater pressure in sediment 

 which had been more rapidly accumulated. 



The Boulder Clay which he had seen in the cuttings south of 

 Willoughby belonged in every case to the main Chalky Boulder Clay. 



The Kev. J. F. Blake remarked on the interest of this paper, as
