Sir, Secondary polygons in Iceland

In his letter, R. W. Reference GrovesGroves (1968) mentions secondary polygons within primary ones, discovered by him on a summit plateau of a 998 m high peak in north-west Iceland. As Mr Groves thinks that this species of patterned ground is “possibly hitherto undescribed”, I wish to point out that I have already described this type of polygon (Thorarinsson, 1953). I observed these polygons in Berufjördur, east Iceland, about 20 m above sea-level, and I later observed the same type of polygon in several other places in Iceland, both in lowland and highland areas.
