deposit at the base of the Rhetic here. The thickness 
of the Bone-bed is noteworthy: it weathers into seven 
main layers, the fourth from the base being an extremely 
hard, light grey, calcareous and slightly pyritic sandstone, 
containing fish remains, and, occasionally, small quartz 
pebbles. Beds 9-13 are compressed and disturbed, and 
considerably more arenaceous than at Wainlode; their 
correlation must be considered approximate. The nodular 
limestone above 7, and intimately connected with that bed, 
was not observed at Wainlode. The outer layer of this 
nodular limestone contains Wodtola minima and Avicula 
contorta. Bed 5 b is closer to 7 here than at Wainlode : 
both beds contain Pecten valontensis. The upper of the 
two (5 b) has deposits of fibrous calcite immediately 
above and below: the lower (7) has a similar, but 
thicker deposit, only below it. A portion of the latter 
I forwarded to Mr Parsons, who furnished me with the 
following note.* “The white amorphous substance is 
earthy gypsum, evidently derived by the action of per- 
colating water on selenite crystals, which occur as harder 
masses in the white substance, though manifestly passing
