This classification is not without value, and a part of his table is As already mentioned the " creamy chalk with nodular flints" belongs to the Middle Chalk, but the position of the " slaty chalk," No. 4, is less certain, for we have not been able to identify it in the Buckton cliffs, and the only other section of it which is clearly located by Mr. Blake (that at Swanland Mill) appears from the fossils to belong to the zone of Hoi. planus. His chalk with many tabular flints is undoubtedly the chalk which both Professor Barrois and ourselves refer to the zone of Hoi. planus, and it is not so barren as Mr. Blake represents, though often so hard that fossils cannot be extracted in good condition. It is clearly the continuation of the similar chalk in Lincolnshire, and a...
