Mr. James W. Davis has contributed eighteen papers on a variety 
of subjects during the period covered by this chapter. Six have 
reference to. fossil fish remains, and one to fossil trees. The erratic 
boulders in the Calder Valley and at Norber are described. Reports of 
the excavation of Raygill fissure, three or four stratigraphical papers; 
two referring to pre-historic man in Yorkshire, and a biographical 
notice of John Phillips. 
At the meeting held at Barnsley in 1879 Mr. Davis read a paper 
on the source of the erratic boulders in the valley of the River Calder, 
entering at greater detail into the question which formed the subject 
of a communication at a previous meeting. At the same meeting 
Dr. H. Franklin Parsons, then of Goole, explained some researches 
he had made on the Trias of the southern part of the Vale of York. 
Two years previously he had read a paper on the alluvial strata of 
this district which envelops the Trias with the exception of a few 
isolated patches. The Triassic rocks are divided into two parts, the 
Keuper consisting of variegated marls, and the Bunter or new Red 
Sandstone. The Keuper rises to the surface in the Isle of Axholme
