or tens of thousands of years, raised the same area, or part of it, 
above the sea, and gave to the British Isles their present surface 
contour. 
Some geologists have attributed . the disturbances exhibited in 
East Anglia in beds, whether of chalk or other deposits, lying on 
or near the surface, to the action of ice. 
See as to this — II. B. Woodward — ‘ Memoirs of the Geological 
Survey of the Country around Norwich,’ p. 134, — in the dis- 
turbances in the chalk at drowse. 
See also a paper — by S. Wood and F. W. Harmer — in the ‘Journal 
of the Geological Society,’ vol. xxxiii. p. S4, on “Glaciated Chalk 
in the Valley of the Yare, near Norwich.” 
He did not question the existence in former times of glaciers in 
the mountains of Scotland and Wales, with the evidence of which 
still remaining in the Vale of Llanberis lie was himself well 
acquainted, but he was altogether opposed to the notion that 
glaciers or ice-sheets ever travelled over East Anglia after it was 
raised from sea. That icebergs melted over this area, when it 
was beneath the sea, is evidenced by the numbers of erratics 
scattered about the present surface. Such phenomena would not 
necessarily imply a colder climate in this part than that of the 
present day. 
Insects erom Narborough and Walton Common on August 5, 
1901. — They included — Pamphila comma , a butterfly previously 
recorded from Norfolk on the streugth of one specimen only, and 
Pamphila tliaumas , a local but much more common species. 
Several moths were shown, the best species being AcidaJia 
rubncata, which occurred Hying in the dryest possible situations, 
and Nonagria typ/uv, bred from pupae found in the stems of 
Bulrushes. The exhibit also included several scarce species of 
Beetles and Bugs, such as Anthocomim sanguinolenfus, which is 
ordinarily found in fens only ; Calyptonotus lynceiut, Coranns 
subapterus, and Nab id boops, which last has a special interest as 
the first British specimens were captured on Mousehold Heath. 
Some specimens of the Colorado Beetle (Chrysomela deccmlineata) 
Mere also shoum. This species has attracted considerable attention 
of late, on account of the discovery of a flourishing colony at 
Tilbury during the present summer. An allied species ( Lema
